--------------
-
-Merged Jeff's changes, 20 Dec 2001:
-
- . Changed all occurrences of "ttnproto == NP_TELNET" to "IS_TELNET()" to
- account for the difference between SSH and Telnet. ckuscr.c,
- ckuus[3457].c, ckcnet.h, ckcfns.c, ckudia.c, ckutio.c, ckucon.c, ckucns.c.
-
- . Moved SSH pty failure warnings. ckuusr.c.
-
- . Security adjustments to FTP module, plus fix an error message. ckcftp.c.
-
- . Adjustment of some security-related #ifdefs. ckcdeb.h, ckuus2.c, ckctel.c.
-
- . Guard against calling getpwnam() with a NULL arg in tilde_expand() ckufio.c.
-
- . Moved getexedir() call to later, where it's safe. ckcmai.c.
-
-Added SSH ADD and many SSH SET commands from Jeff's spec. Fixed SHOW SSH
-to not dump core if variables weren't set. ckcker.h, ckuus[r3].c, 20 Dec 2001.
-
-C-Kermit in server mode, client says "get foo" where foo is a symlink.
-Server says "no files meet selection criteria" instead of sending the file.
-It should only refuse to follow symlinks if it's a recursive get. Fixed
-in sgetinit(): ckcpro.w, 21 Dec 2001.
-
-More work on SSH and SET/SHOW SSH commands. ckuus[r3].c, 21 Dec 2001.
-
-Undid Jeff's replacement of the SSH pseudoterminal allocation failure
-message, because now it comes out any time an SSH command has to be
-reparsed (in the non-SSHBUILTIN case). ckuusr.c, 21 Dec 2001.
-
-More SSH and SET SSH command work back & forth with Jeff, plus Jeff added
-SET HOST /NET:SSH. ckcmai.c, ckuus[r37].c, ckcdeb.h, ckuusr.h, 22 Dec 2001.
-
-Added SSH OPEN switches. ckuusr.c, 22 Dec 2001.
-
-Added SSH CLEAR, HELP SSH, and HELP SET SSH. ckuus[r2].c, 23 Dec 2001.
-
-From Jeff:
- . SET TCP commands now apply to SSH
- . SSH V2 REKEY and FORWRD-{LOCAL,REMOTE}-PORT commands now implemented
- . Missing DLLs automatically disable appropriate authentication mechanisms.
-ckuusr.c ckcnet.c ckuus3.c ckcmai.c ckcnet.h ckuus4.c, 26 Dec 2001.
-
-From Jeff:
- . Remove SET SSH KEEPALIVES.
- . Add help text for SSH AGENT { ADD, DELETE, LIST }.
-ckuus[23].c, 28 Dec 2001.
-
-Added parsing for SSH AGENT { ADD, DELETE, LIST }. ckuusr.c, 28 Dec 2001.
-
-From Jeff:
- . Fixed a crash that can happen when making an SSH connection.
- . Filled in SSH AGENT actions.
- . Changed default for strict host key check (to ASK) and help text.
- . uploaded new binaries include ~kermit/os2test/beta/ssh-agent.exe
- . Read man ssh-agent on ftp.kermit.columbia.edu for details on what it does.
-ckuus[r23].c, 28 Dec 2001.
-
-"ftp get path/filename" didn't work; the FTP client did not strip the path
-from the local copy of the filename when doing a GET, even though it did
-for MGET. Diagnosis: in doftpget(), the "if (!getone && !skipthis)" statement
-lacked an "else" part for the getone case. ckcftp.c, 28 Dec 2001.
-
-A while back Jeff reported that in FTP MGET, if you cancel a file with 'x',
-all the rest of the files arrive truncated to 0 bytes. I tried this on both
-Unix and Windows and couldn't reproduce it.
-
-In the last-minute flurry to release C-Kermit 8.0, I thought I noticed the FTP
-client failing to update the fullscreen file-transfer display. But it seems
-to work right, at least in Unix. When downloading a big file with FTP, all
-the display fields are updated as expected. But smaller files might go by too
-fast for the display to do anything. HOWEVER, in K95 the file transfer
-display does not update itself until the end of the file, even if the file
-takes a long time to transfer. This happens in both the Console and GUI
-versions. A thread thing? (Jeff says no.) Yet the same display works fine
-on Telnet connections.
-
-In IRIX 5.3, the select()-based CONNECT module had to include <sys/time.h>
-or else it blew up with "struct timeval" unknown. Since there already was
-a SYSTIMEH CFLAG, I added the #include within #ifdef SYSTIMEH..#endif and
-rebuilt with KFLAGS=-DSYSTIMEH, only to discover that the irix5* targets
-didn't bother to propogate KFLAGS. Fixed in ckucns.c, makefile, 30 Dec 2001.
-
-Increased IRIX5x Olimit from 2400 to 3000 because of ckuus[34].c. Added
--ansi, since (Marcus Herbert reported) we were not actually getting ANSI-C
-compilation even though CK_ANSIC was defined. But now that we are, we get
-warnings in <netinet/tcp.h>, which is included by ckcnet.h:
-
- bit-field 'th_off' type required to be int, unsigned int, or signed int.
- (3.5.2.1(30))
- u_char th_off:4,
- ------ ^
-Tough. makefile, 30 Dec 2001.
-
-But adding -ansi to the IRIX 5x targets also make compilation bomb whenever we
-referenced fdopen() or popen(), which evidently don't have prototypes in any
-of the header files. Luckily we already have CFLAGS for this occasion too:
-DCLFDOPEN and DCLPOPEN. Added these to the irix51 target. Also had to copy
-the fdopen()-popen() prototype section to ckuusx.c, which has a new reference
-to fdopen() in a workaround for the curses console buffering bug. makefile,
-ckuusx.c, 30 Dec 2001.
-
-The QNX6 version did not receive a proper herald (it announced itself as
-"unknown version". Reshuffled #ifdefs in ckuver.h, added display of QNX6
-and NEUTRINO symbols to ckuus5.c, 30 Dec 2001.
-
-Lucas Hart sent in a patch for the VMS problem. Apparently it was even worse
-than Dave Sneddon had reported: 8.0 couldn't run at all under Batch. ckvtio.c,
-31 Dec 2001.
-
-A major obstacle to the usability of the FTP client is that certain commands
-don't behave as FTP users expect: CD, DIR, DELETE, MKDIR, etc, which are local
-rather remote, and there are no LCD (etc), USER, or ACCOUNT commands. We
-could fix this by adding an FTP command-language personality, but file
-management commands can also be remote or local on connections to Kermit
-servers too. So:
-
-SET LOCUS { LOCAL, REMOTE, AUTO }
- Sets the locus for unprefixed file management commands.
- When LOCAL, a REMOTE (or R) prefix is required for
- to send file management commands to a remote server (e.g. RCD, RDIR).
- When REMOTE, an L prefix is required to issue local file management
- commands (e.g. LCD, LDIR). The word LOCAL can't be used as a prefix
- since it is used for declaring local variables.
-
-This applies to all types of connections, and thus is orthogonal to SET
-GET-PUT-REMOTE, which selects between Kermit and FTP for remote file-transfer
-and management commands.
-
-The default LOCUS is AUTO, which means we switch to REMOTE whenever an FTP
-connection is made, and to LOCAL whenever a non-FTP connection is made,
-and switch back accordingly whenever a connnection is closed.
-
-Implementation (31 Dec 2001):
- . None of this is compiled if LOCUS is not defined.
- . Added XYLOCUS (SET LOCUS) and LOCUS definitions: ckuusr.h.
- . Override by defining NOLOCUS (which inhibits definition of LOCUS).
- . Added LOCUS to SET keyword table: ckuusr.c.
- . Added locus & autolocus variables: ckuusr.c.
- . Added SET LOCUS parsing and variable setting: ckuus3.c.
- . Added display of LOCUS setting to SHOW COMMAND: ckuus5.c.
- . Added automatic locus setting to setlin(): ckuus7.c.
- . Added automatic locus setting to ftpopen() and ftpclose(): ckcftp.c.
-
-How to catch all the places where a Kermit connection is closed? Turns out
-we've done this before, when we added the connection log. So I made
-dologend() take care of locus switching. But dologend() was not compiled in
-if certain symbols were defined, such as NOLOCAL, or not defined, such as
-CKLOGDIAL. So I (a) rearranged the #ifdefs so that even if these would
-otherwise have obliviated dologend(), now they leave a piece of it for
-locus-setting; (b) moved the prototype out of #ifdefs; and (c) took all calls
-to it out of #ifdefs. ckcker.h, ckcfn2.c, ckcmai.c, ckucns.c, ckucon.c,
-ckuus[r347x].c, 31 Dec 2001.
-
-Added locus checking to the following commands: DIRECTORY, CD/CWD, CDUP,
-DELETE, PWD, MKDIR, RMDIR, RENAME. ckuusr.c, 31 Dec 2001.
-
-Added LDIRECTORY, LCD/LCWD, LCDUP, LDELETE, LPWD, LMKDIR, LRMDIR,
-LRENAME. ckuusr.[ch], 31 Dec 2001.
-
-Added USER and ACCOUNT commands, which are the same as FTP USER and FTP
-ACCOUNT. ckuusr.[ch], ckcftp.c, 31 Dec 2001.
-
-Since automatic locus switching could be a big surprise for most people, I
-printed message any time it changed. ckcftp.c, ckuus[37].c, 31 Dec 2001.
-
-Added help text for the new L commands and filled in missing HELP text for
-SET GET-PUT-REMOTE, CDUP, MKDIR, and RMDIR. ckuus2.c, 31 Dec 2001.
-
-Changed help text of CD, DIR, etc, for LOCUS. Changed the help text for
-RCD, RPWD, RDEL, RDIR, etc, to mention that they also work with FTP servers.
-Updated HELP REMOTE for this too. ckuus2.c, 31 Dec 2001.
-
-Made sure code builds with NOLOCAL, NOLOGDIAL, and NOLOCUS (it does).
-
-The IKSD command, when given with a /USER: switch, sends the user ID to the
-IKSD. But the SET HOST /USER: command does not, when making a connection to a
-Kermit service. This makes it impossible to script IKSD interactions using
-only client commands. Furthermore, even if you include a /PASSWORD switch
-with the IKSD command, it does not send the password. I added code near the
-bottom of setlin() to do this. If we have a connection to a Kermit service
-and a /USER: switch was given, then we attempt a REMOTE LOGIN. If a
-/PASSWORD: switch was not given then if the username is "ftp" or "anonymous",
-we automatically supply a password of user@host; otherwise we prompt for a
-password. If a /USER: switch was not given, it acts like before. It all
-works, but it might not be the best way (or place) to do it. setlin():
-ckuus7.c, 31 Dec 2001.
-
- NOTE: The above change doesn't help with IKSD /USER:anonymous,
- the server prompts for password anyway, not sure why.
-
- NOTE 2: What about secure authentication? We have to test to see
- if user was already authenticated before sending the login packet.
-
-Added /opt/kermit and /opt/kermit/doc to info_dir[] list (for Solaris).
-ckuus5.c, 31 Dec 2001.
-
-From Jeff: new Help text for SET TERM FONT (K95 GUI). ckuus2.c, 1 Jan 2002.
-
-More work on help text for file management commands -- e.g. we can't lump
-the L-commands together with the unprefixed ones; they need separate entries.
-Also: added missing HELP REMOTE PWD, improved the default case (in which
-help text had been omitted for a valid command). ckuus2.c, 1 Jan 2002.
-
-It seems VMS C-Kermit was pretty much ignoring the -B (force background) and
--z (force foreground) command-line options. Fixed in congm(): ckvtio.c,
-1 Jan 2002.
-
-Tested the SET LOCUS business with VMS C-Kermit, which does not have a
-built-in FTP client. Of course in this case there is no automatic locus
-switching, but SET LOCUS REMOTE works nicely on IKSD connections.
-
-From Jeff:
- . #ifdef adjustments for LOCUS changes.
- . SSH KEY CREATE /TYPE:SRP.
- . Fix \v(serial) to not be 8N2 by default if speed is 0.
- . Don't let doexit() run if sysinit() hasn't been called first.
-ckuus[r247x].c, 2 Jan 2002.
-
-Made SET BACKGROUND { ON, OFF } do exactly the same as -B and -z options.
-ckuus3.c, 2 Jan 2002.
-
-Updated user-visible copyright dates to 2002 (but still need to do all the
-source-module comments). ckcmai.c, ckuus[25].c, 2 Jan 2002.
-
-Rearranged #include <sys/time.h> in ckucns.c that was done for IRIX 5.3,
-to avoid conflicts in SV/68 R3v6. 3 Jan 2002.
-
-From Dave Sneddon: Code changes in VMS sysinit() and congm() to work around
-problems in batch, SPAWN'd, etc, and change CTTNAM from TT: to SYS$INPUT:.
-ckcdeb.h, ckvtio.c, 3 Jan 2002.
-
-From Jeff:
- . Fixed typo in definition of CTTNAM for VMS. ckcdeb.h
- . Moved macro definitions for SSHBUILTIN from ckuus3.c to ckuusr.h
- so they can be referenced in ckuus7.c
- . Added SSH functionality to SET HOST:
- SET HOST /NET:SSH /CONNECT hostname [port] /switches
- . Fixed SET NET TYPE so it won't reject SSH if SSH is installed.
- . Changes to allow IKSD to continue functioning. Somehow this minor change
- to ckcmai.c got lost in one of the back and forth exchanges.
- . HELP TEXT for UCS2 kverb
- . Fix a problem in K95 where multiple threads could be attempting to
- send a telnet negotiation simultaneously.
-ckcmai.c ckcdeb.h ckuus2.c ckuus3.c ckuusr.c ckuusr.h ckuus7.c ckctel.c
-ck_crp.c ckuat2.h ckuath.c, 4 Jan 2002.
-
-From Jeff:
-
- Peter Runestig complaining that the Telnet Forward X code was corrupting
- data. This resulted in a very thorough examination of the telnet module
- code and a discovery of some rather significant problems. The root of the
- problems is the lack of thread safety. To correct this problem the
- following was done.
-
- All code (regardless of module) which outputs telnet commands is placed
- into a mutex region to ensure that competing output threads do not result
- in interleaving their output. This could happen for instance when the
- forward-x thread is forwarding data and the user changes the window size
- or sends an AYT or BREAK. Next the buffer used for input and output
- processing were identical. This means that output data could be treated
- as input or vice versa. Ugh....
-
- I also spent some more time cleaning up setlin(). Mostly reorganizing the
- code into single if (...) blocks so that breaking it up will be easier.
-
-ckctel.c ckuus7.c, 4 Jan 2002.
-
-Updated internal copyright notices. All modules, 5 Jan 2002.
-
-From Jeff:
- More of same, plus new makefile target and changes from Spike Gronim
- for freebsd44+srp+openssl.
-ckcdeb.h ckcnet.c ckctel.c ckuus7.c ck_ssl.c makefile, 5 Jan 2002.
-
-Some minor updates and fixes to SSH and SET SSH help text.
-ckuus2.c, 6 Jan 2002.
-
-Added SET RGB-COLORS for GUI. ckuusr.[ch], ckuus3.c, 6 Jan 2002.
-
-From Jeff: More Telnet changes, Debug semaphores for K95, etc: ckcdeb.h,
-ckuusr.h, ckuus[r35x].c, ckctel.[ch], ckuath.c, 7 Jan 2002.
-
-Added --xpos:n --ypos:n, SET GUI WINDOW POSITION x y, and changed SET
-RGB-COLORS to SET GUI RGBCOLOR. Action needs to be filled in (in setguiwin()
-in ckuus3.c), and gui_xpos and gui_ypos need to be defined in cko???.c.
-ckuusr.h, ckuus[r3y].c, 7 Jan 2002.
-
-Added --fontname:name --fontsize:name (and facename as synonym for fontname).
-ckuusr.h, ckuus[7y].c, 7 Jan 2002.
-
-Moved GUI (not OS/2) SET TERM FONT code in ckuus7.c to its own routine,
-setguifont(), in ckuus3.c, and made GUI SET TERM FONT call this routine,
-and also made SET GUI FONT call the same routine. ckuus[37].c, 7 Jan 2002.
-
-Added --termtype:, --height:, --width:, --user:. Also added symbols for
---telnet:, --ssh:, --ftp:, --[remote-]charset, and --password:, but didn't
-fill them in. --password: is probably not a good idea (but we allow it for
-FTP); the others involve a lot of code-shuffling and reconciliation, which
-I'll try to do when I get a chance (especially the connection ones, which
-can be done as part of the setlin() restructuring). ckuusr.h, ckuusy.c,
-8 Jan 2002.
-
-Also I tried commenting out the #ifndef KUI..#endif's around SET TERMINAL
-CHARACTER-SET (easier said than done because a crucial #endif was mislabeled).
-Let's see if it compiles & works... ckuus7.c, 8 Jan 2002
-
-Added FTP [ OPEN ] /NOINIT, meaning don't send REST, STRU, and MODE commands
-upon making an FTP connection. This allows connection to servers that close
-the connection (or worse) when given these commands (e.g. Linux 2.4 TUX 2.0
-FTP server). ckcftp.c, 8 Jan 2002.
-
-Looked at adding caller ID support for the ANSWER command:
-
- . SET ANSWER CALLER-ID { ON, OFF }
- . SET ANSWER RINGS <number>
- . \v(callid_xxx) xxx = { date, time, name, nmbr, mesg }
- . CKD_CID modem capability
- . Set CKD_CID for modems that have it.
- . A quick survey shows:
- - USR V.90: No (but Jeff says some USRs have it).
- - V.250: No
- - Lucent Venus: No
- - USR: #CID=1 (the ones that have it -- X2?)
- - Diamond Supra: #CID=1
- - Rockwell 56K: #CID=1
- - PCTEL: #CID=1
- - Zoltrix: +VCID=1
- - Conexant: +VCID=1
- . Since there are different commands to enable caller ID reporting,
- we need a new field in struct MDMINF.
- . SHOW MODEM and SHOW DIAL would need updating.
- . etc etc...
-
-This is all way too much for now so I just did the setting of the \v(callid_*)
-variables. These are reset at the beginning of an ANSWER command, and then
-set by the ANSWER command if they come in; thus they persist from the time
-they are collected until another ANSWER command is given. To take advantage
-of autoanswer, the user has to enable it in the modem (all the modems I found
-that support it have it disabled by default), and also has to set the number
-of rings to at least 2. This can be done with (depending on the modem):
-
- set modem command autoanswer on ATS0=2#CID=1\{13}
- set modem command autoanswer on ATS0=2+VCID=1\{13}
-
-and undone with:
-
- set modem command autoanswer on ATS0=1#CID=0\{13}
- set modem command autoanswer on ATS0=1+VCID=0\{13}
-
-The variables can be accessed only after the call is answered. Therefore the
-only way to refuse a call is to answer it, inspect the variables, and then
-hang it up if desired. Future Kermit releases can do this more nicely (as
-sketched out above.) Also while I was in the dialing code, I added result
-code VCON (= VOICE), used by several of the newer modems. These changes are
-untested. The SET ANSWER command is written but commented out. ckuusr.h,
-ckcker.h, ckuus[r3].c, ckudia.c, 8 Jan 2002.
-
-From Jeff: fixes to --termtype:, --height:, --width:, --user:, and filling in
-of --rcharset:, which required extracting code from settrm() into a separate
-parse-method-independent remote character-set setting routine. ckuus[7y].c,
-8 Jan 2002.
-
-From Jeff: More work on TERMINAL CHARACTER-SET code reorganization, and
-reinstatement of SET TERMINAL CHARACTER-SET in K95G. Also, fix char/CHAR
-warnings in Telnet module. ckuus7.c, ckctel.c, 9 Jan 2002.
-
-Made SET TERM CHARACTER-SET visible for all builds, including K95G, and filled
-in HELP text for it. ckuus[27].c, 9 Jan 2002.
-
-Added help text for new extended options. ckuusy.c, 9 Jan 2002.
-
-Commented out the return(-2) statement at the end of xgnbyte() to make the
-"Statement not reached" errors go away, after checking to make sure that there
-was no path that could fall through to the end. I'm 99.99% sure there isn't,
-but that doesn't mean that some compilers might not still complain. ckcfns.c,
-9 Jan 2002.
-
-From Jeff: fix typo in the K95 extended-option help text; add more
-semaphores to network i/o. ckuusy.c, ckcnet.c, 10 Jan 2002.
-
-Undid ansiisms in set{lcl,rem}charset() declarations. ckuus7.c, 10 Jan 2002.
-
-Removed a duplicated clause from the install target. makefile, 10 Jan 2002.
-
-From Jeff: more semaphores. ckcnet.c, 11 Jan 2002.
-
-Moved references to tmpusrid and tmpstring out of NOSPL #ifdefs -- they can
-be used with NOSPL. setlin(): ckuus7.c, 13 Jan 2002.
-
-Made a dummy dologend() routine outside of #ifndef NOICP, so we don't have
-to enclose every reference to dologend in #ifdefs. (I had added a bunch of
-calls to dologend() throughout the code to handle automatic LOCUS switching.)
-ckuus3.c, 13 Jan 2002.
-
-Moved "extern int nettype" outside of NOICP #ifdefs in ckuus4.c for NOICP
-builds. 13 Jan 2002.
-
-Moved a misplaced #ifdef in the VERSION command. ckuusr.c, 13 Jan 2002.
-
-Did 81 different feature-selection builds on Linux (RH 7.0), all OK after the
-changes listed above for today. 13 Jan 2002.
-
-Added prototypes for set{rem,lcl}charset(). ckcxla.h, 13 Jan 2002.
-
-Added ckcxla.h to dependencies for ckuusy.c. ckvker.com, 13 Jan 2002.
-
-Made a correction to the HELP SET LOCUS text and supplied a missing comma
-for HELP REMOTE. ckuus2.c, 13 Jan 2002.
-
-Built OK on HP-UX 11.11 (K&R and ANSI), Solaris 8 (cc), Solaris 2.5.1 (gcc),
-SunOS 4.1.3 (cc and gcc), VMS 7.1 (DEC C, net and nonet), Unixware 7.1.1,
-Tru64 4.0G, HP-UX 10.20 (K&R), AIX 4.3.3, FreeBSD 2.2.8, Slackware 8.0, IRIX
-6.5.13f, IRIX 5.3 (??? Can't tell -- the computer ran out of swap space -- but
-it was OK a few days ago), VMS 5.5-2 (VAX C, UCX + nonet)... HP-UX 9.05, ...
-
-Some corrections to comments in HP targets from PeterE. makefile, 14 Jan 2002.
-
-Corrections to prototypes for set{rem,lcl}charset() (VOID, not void) from Jeff.
-ckcxla.h, 14 Jan 2002.
-
-Builds, cont'd... SINIX 5.42, Red Hat Linux 5.2 on i386, SuSE 7.0 on S/390,
-Red Hat 7.1 on IA64, QNX 4.25, HP-UX 5.21/WinTCP, ...,
-
-Dell Coleman <dell@aleph.tum.com> noticed that in AIX, the COPY command always
-says "Source and destination are the same file" when the destination file
-doesn't exist. This is because in AIX, realpath() fails with ENOENT (errno
-2). The zfnqfp() code already accounts for this, but evidently not well
-enough. So I did what I should have done long ago. zfnqfp() was originally
-accomplished with do-it-yourself code. Later I added support for realpath(),
-and partitioned the routine into mutually exclusive compile-time sections:
-#ifdef CKREALPATH realpath()... #else do-it-yourself... #endif. But if
-realpath() failed, there was no recourse to the do-it-yourself code. Today I
-replaced the #else with the #endif, so the do-it-yourself part is always
-included and is executed if the realpath() call fails. Built and tested on
-AIX 4.3.3 and Solaris 2.5.1, as well as on Linux with and without the
-realpath() code included. zfnqfp(): ckufio.c, 16 Jan 2002.
-
-Separated K95 and C-Kermit test version numbers, so C-Kermit can be RC.02
-while K95 is Beta.01. ckcmai.c, 16 Jan 2002.
-
-Inhibited 0-length writes by conol() and conoll(), since they cause big
-trouble with the AIX 4.3.3 pty driver, e.g. when you have an SSH connection
-into AIX and run C-Kermit there. ckutio.c, 16 Jan 2002.
-
-Suppressed "Switching LOCUS..." messages from FTP client when it was invoked
-from the command line. ckcfns.c, 17 Jan 2002.
-
-Dave Sneddon noticed that FOPEN /APPEND gets "?Write access denied" in VMS
-if the file exists. This is apparently because VMS zchko() does the wrong
-thing. Commenting out the call zchko() in the VMS case gets past this but
-then the appended part of the file has different attributes than the orignal
-part, e.g.:
-
- abc <- original line (horizontal, normal)
- d <- appended line (vertical)
- e

-VMS fopen() takes an optional 4th argument: a series of RMS keyword=value
-pairs. Kermit doesn't give any. Experimentation shows that appending to
-a Stream_LF works fine. That'll be a restriction for now, until somebody
-sends in code to get the RMS attributes of the original file and feed them
-to fopen(). Also need code to fix VMS zhcko() to say whether it's OK to
-append to a file. ckuus7.c, 17 Jan 2002.
-
-Somebody suggested I could get a working Kermit for Neutrino 2+ by doing the
-QNX6 build on Neutrino itself. I verified that this can't be done -- at least
-not by me -- since Netutrino 2+ doesn't have a compiler, and we already know
-the version cross-built for it on QNX4 doesn't work. 17 Jan 2002.
-
-From Jeff: SET SSH GSSAPI KEY-EXCHANGE { ON, OFF } parsing, SHOW SSH.
-ckuus3.c, 18 Jan 2002.
-
-PeterE suggested that SET ESCAPE allow 8-bit escape characters because of the
-difficulty in entering Ctrl-\ on European keyboards and the hardship (e.g. to
-EMACS and VI users) of sacrificing another C0 control character. Like
-everything these days, this turns out to be rather a bigger deal than it would
-seem. The SET ESCAPE parser calls setcc(), which accepts control characters
-in various formats (literal, ^X notation, or numbers), and gives an error
-return if the value is not 0-31 or 127. This is changed easily enough to also
-allow numbers between 128 and 255. But who else calls setcc()? The commands
-for setting Kermit packet start and end characters. No big deal, this gives
-people a bit more flexibility in case they need it, but it won't be
-documented. setcc(): ckuus7.c, 18 Jan 2002.
-
-Since code to display the escape character is scattered all over the place,
-and some of it indexes into an array based on the character value (which would
-now dump core if the escape character was > 128), I put the code in one place,
-a new shoesc() routine in ckuusx.c (which needs to be outside #ifndef NOICP,
-since the CONNECT modules use it even in command-line only builds). Also
-discovered that this code was indexing into the nm[] array with tt_escape to
-get "enabled" or "disabled", which is no longer appropriate, so fixed this
-too. ckuusr.h, ckuus[5x].c, 18 Jan 2002.
-
-Made SHOW ESCAPE, SHOW TERM, and the various CONNECT modules call shoesc(),
-and updated HELP SET ESC. ckuus[25].c, ckucns.c, ck[cuvd9]con.c, 18 Jan 2002.
-
-After all that, it occurred to me that this is a really bad idea for K95,
-with all the confusion about Console code pages, OEM code pages, Windows
-code pages, and Unicode. But I tried "echo \161" at the K95 prompt and got
-the expected 8-bit character in both the Console version and the GUI, so
-maybe it's OK after all.
-
-Removed the automatic IKSD login code from setlin() since it complicates
-interactive anonymous login. ckuus7.c, 20 Jan 2002.
-
-An #ifdef clause from Matthew Clarke to avoid "redeclaration of free" error
-when building a curses version of C-Kermit for AIX 2.2.1 on RT PC. ckuusx.c,
-22 Jan 2002.
-
-Took care of one detail I omitted when adding the 8-bit escape character:
-not stripping the 8th bit before comparing the keyboard char with the escape
-char. ck[uv]con.c, ckucns.c, 24 Jan 2002.
-
-Started to go through Jeff's changes of the last week but he had run trim -t
-on them, which untabifies, so the diffs were huge. Retabifying Jeff's files
-only makes matters worse. So instead of comparing each old and new source
-file in EMACS windows with M-X Compare-Windows like I usually do (which can't
-be told to ignore whitespace), I had to work from the diff -c -b listings.
-In ascending order of size of diffs:
-
-ckcker.h: Add I_AM_SSHSUB definition.
-ckuusr.h: XXLINK and VN_PERSONAL, etc, definitions.
-ckuusy.c: Support for "I Am SSHSUB" invocation.
-ckuus5.c: Support for new K95 directory structure.
-ckcmai.c: Init endianness earlier (K95 TYPE was broken), "I Am SSHSUB" support.
-ckuus7.c: Security #ifdefs, SSH OPEN /PASSWORD, SSHSUB support
-ckcftp.c: <-- SAVE TIL LAST
-ckuus6.c: Add LINK command for K95 on NT.
-ckuus4.c: Support for new K95 directory structure; SSHSUB support
-ckuus3.c: Support for new K95 directory structure; some SSH changes
-ckuus2.c: Changes to SSH related help text, add HELP LINK text
-ckuusr.c: LINK command, SSH OPEN /PASSWORD: /SUBSYSTEM: switches,
- Pattern-management fixes.
-ckctel.c, ck_ssl.c, ckuath.c, ckcnet.c:
- Took Jeff's without looking.
-ckuusx.c, ckucns.c, ckucon.c, ckwart.c:
- My changes from weeks ago that were never picked up.
-
-Built OK on Solaris with gcc and on SunOS with (K&R non-ANSI) cc.
-31 Jan 2002.
-
-Meanwhile, Jeff had made various changes in response to Jaya Natarajan at IBM,
-whose basic complaint was that numerous failure conditions were not being
-detected if the fullscreen file-transfer display was active. Jeff found that
-this was because big blocks of code were skipped in that case and changed the
-code not to do that, which fixed the reported problems. But later Jaya said
-that "ftp mget file1 file2" acted like "ftp mget *", so it seemed that Jeff's
-fixes broke file selection. After taking Jeff's fixes for ckcftp.c, however,
-I still could not reproduce the problem. ckcftp.c, 31 Jan 2002. <-- Later,
-it turned out the problem was with IBM's custom FTP server.
-
-Fixed updates that I missed yesterday in ckcftp.c, ckuusr.c. Moved misplaced
-#ifdef in ckuusy.c breaking nonet builds. Added #ifdefs to sysinit() for
-nonet builds in ckutio.c. Ran through build-in-many-configurations script
-in Linux, all builds OK. 1 Feb 2002.
-
-Moved shoesc() definition outside of NOXFER to fix NOXFER builds.
-ckuusx.c, 1 Feb 2002.
-
-Added MYCUSTOM definition alongside KERMRC and changed KERMCL to be the
-same as CKMAXPATH, instead of some random hardwired number. ckuusr.h,
-1 Feb 2002.
-
-Changed ckcdeb.h to define DIRSEP and ISDIRSEP(), and put #ifndef
-[IS]DIRSEP..#endif around all [IS]DIRSEP definitions in ck[udso]fio.c, so we
-can finally put away the many repeated #ifdef chains when we get around to it.
-1 Feb 2002.
-
-Make VMS zkermini() return 1 on success, 0 on failure, rather than 0 always.
-ckvfio.c, 1 Feb 2002.
-
-Added code to doinit(), just before it goes to execute the init file. If the
-init file name we are about to open is empty or fails zchki(), substitute the
-customization filename. For now this code is in #ifdef USE_CUSTOM..#endif,
-which is not defined by default. It does the trick in Unix and VMS. Also
-included code from Jeff for K95, but this needs verification and testing.
-Also used DIRSEP and ISDIRSEP() throughout doinit() instead of the long #ifdef
-chains. ckuus5.c, 1 Feb 2002.
-
-Moved shoesc() prototype from ckuusr.h to ckcker.h so modules that need it
-don't have to include ckuusr.h just for this one thing (example: ckvcon.c).
-1 Feb 2002.
-
-Defined USE_CUSTOM by default, except if NOCUSTOM is defined. ckuusr.h,
-1 Feb 2002.
-
-Fixed kermit-sshsub code to really enter server mode, and to print
-"KERMIT READY TO SERVE..." so scripts can wait for it. Also bumped the
-C-Kermit test ID to RC.03 and the K95 one to Beta.02. ckcpro.w, ckcmai.c,
-2 Feb 2002.
-
-I was thinking about adding SET COMMAND BUFFER-SIZE to let people allocate
-as big a buffer as they wanted at runtime, mainly for defining huge macros.
-Moved the SCMD_blah definitions from ckuusr.h to ckuus3.c, since they aren't
-used anywhere else. But stopped there since the rest turns out to be a rather
-big deal. ckuusr.h, ckuus3.c, 2 Feb 2002.
-
-From Jeff, 3 Feb 2002:
- . Fix an out-of-order modem name in the SET MODEM TYPE table: ckudia.c.
- . Use SET LOGIN USER and PASSWORD if present. ckcftp.c.
-
-Cody Gould noticed that array declarations had become case sensitive, and
-upper case didn't work. Diagnosis: misplaced case conversion in xarray().
-Fixed in ckuus5.c, 4 Feb 2002.
-
-SHOW VAR dumps core on \v(sexpression) or \v(svalue) -- failure to check for
-NULL pointer. I wonder why this didn't happen before (answer: because I was
-doing it on SunOS; now I'm doing it on Solaris). ckuus4.c, 6 Feb 2002.
-
-I've had several requests for "show var name name name...". I added this to
-doshow(), such that SHOW VAR works exactly as it did before (if you don't give
-it an arg, it lists all variables; if you give it an arg, it appends "*" to it
-and lists all matching variables) but now you can also give more than one arg
-and it works the same way with each one as it did before if you gave it a
-single item (i.e., "*" is appended, so "show var os cmd" shows all variables
-whose names begin with "os" or "cmd". You can also freely use pattern
-notation, including anchors. Hmmm, no, actually it's different in that now
-each includes an implied * before AND after, so "show var version" shows all
-variables whose name contain "version" rather than all variables whose names
-start with it. ckuus5.c, 6 Feb 2002.
-
-Cody Gould reported that WRITE FILE blah blah \fexec(anything) ... got a
-spurious "File or Log not open" error. This turns out to be a rather
-pervasive problem -- whenever you use \fexec() it calls the parser recursively
-and this can run roughshod over global variables, such as our innocent little
-x, y, and s. The fix in this case was to put x and y on the stack. The same
-thing probably needs doing in about 10,000 other places. Too bad C isn't
-Algol. ckuusr.c, 6 Feb 2002.
-
-Minor fix to SHO VAR -- the "^" anchor wasn't working (e.g. "show var ^os").
-ckuus5.c, 6 Feb 2002.
-
-Fixes from Jeff for FTP file-transfer character-set translation in K95 and
-in WIKSD, plus updated K95 SSH help text. ckcftp.c, ckcfns.c, ckuus2.c,
-7 Feb 2002.
-
-Server has its date set in the past. Client says "remote dir". Server sends
-A packet containing old date. If client has FILE COLLISION UPDATE, it
-rejects the directory listing. Changed gattr() to only reject real files
-(introduced by F packet), not X-packet material like directory listings.
-ckcfn3.c, 7 Feb 2002.
-
-Up-down arrow keys for command recall. People have been asking for it for
-years but now it's actually important because of PDAs that don't have Ctrl
-keys. Would have been trivial except that we use getchar() rather than
-coninc() for reading from the keyboard in Unix so conchk() doesn't help. In
-fact there are lots of other places where conchk() is used this way and works
-only by accident. The only reason we never noticed a problem before is that
-characters don't usually arrive from the keyboard that fast. But when an
-arrow key sends "ESC [ A" all once, the stdin buffer gets some extra stuff in
-it, which getchar() will return next time, but which coninc()/conchk() will
-never see. So I added a new cmdconchk() routine which, if the keyboard is
-being read with getchar() rather than coninc(), looks at the stdin buffer.
-Unfortunately, however, there is no API for this, nor is there any standard
-way to access the stdin buffer directly. So first I did it for Solaris. Then
-to make it portable requires a survey of the headers for every platform. I
-found four major variations:
-
- stdin->_r:
- {Free,Open,Net}BSD, BSDI
- stdin->_cnt:
- SunOS, Solaris, HP-UX 5-6, AIX, VMS, SINIX, IRIX 5.3-6.5, DGUX
- 4.2BSD, 4.3BSD, OSF/1..Tru64, QNX4, Unixware 1.0-2.1.0
- stdin->__cnt:
- HP-UX 7-11, SCO: OSR5.0.6a, Unixware 2.1.3-7.x, OU8, UNIX 3.2v4.x
- Subtract read from end pointer (_IO_file_flags defined):
- Linux (tested on RH 5.2 thru 7.1)
-
-The Linux method is new and different to account for multibyte characters.
-All the others assume character == byte.
-
-For docs: ANSI only, 7-bit only; both application and cursor modes are
-accepted. Only up and down arrow are handled; left and right arrows cause
-a beep. ckucmd.c, 8 Feb 2002.
-
-Build-all: Discovered that changing CTTNAM from TT: to SYS$INPUT: in VMS
-(which was done on 3 Jan 2002 to work around problems starting Kermit in
-batch, spawn'd, etc) breaks Kermit on VMS 5.5/VAX (concb() fails with "lacks
-sufficient privilege"; if you enable all privs Kermit starts but then spews
-out a constant stream of BEL characters). If you put dftty back to "TT:",
-everything is fine -- I have no idea why, so I used #ifdef VMSV70 to decide,
-which is totally crude. Next I had to find where the boundary really is: VAX
-vs Alpha? VAX C vs DEC C? Or between VMS releases? Built on:
- . VMS 6.2 Alpha (DEC C) - OK with TT:
- . VMS 6.2 Alpha (DEC C) - OK with SYS$INPUT: <-- keep this one
- . VMS 7.1 VAX (DEC C)
-So the final condition is #ifdef VMSV60. ckvker.com, ckvtio.c, ckuus5.c.
-
-QNX 6 needed some attention too:
- . Whoever did the makefile target made the default port "/dev/ser1".
- . Arrow keys...
-But I gave up on getting arrow keys to work -- it should be just like *BSD,
-but for some reason gcc complains that struct FILE has no _r member, even
-though it does (getchar uses it).
-
-Checked stdio.h on Mac OS X and it looks like the *BSDs.
-
---- C-Kermit 8.0.201 ---
-
-Removed -g from solaris2xg+krb5+krb4+openssl+shadow makefile target -- it
-was producing a 15MB binary! makefile, 14 Feb 2002.
-

-(tarball refreshed 16 Feb 2002)
-
---- C-Kermit 8.0.201 ---
-
-From Jeff: Better seeding of \frandom(): ckcmai.c, ckuus4.c, 18 Feb 2002.
-
-From Jeff: Make arrow keys work in WIKSD, but now also unconditionally
-compile arrow-key code in all versions. ckucmd.c, 18 Feb 2002.
-
-From Jeff: ckuath.c, ck_ssl.c, ckcnet.c (didn't look). 18 Feb 2002.
-
-Added ORIENTATION command, that lists the various important directories, and
-\flongpathname() and \fshortpathname(), which do path format conversions in
-Windows, and are just synonynyms for \fpathname() elsewhere. The new functions
-need building and testing in Windows. ckuusr.h, ckuus[r24].c, 18 Feb 2002.
-
-Changed PWD for Windows only to show both short and long paths (but only if
-they are different; otherwise it behaves as before). ckuusr.c, 18 Feb 2002.
-
-Changed default Windows prompt to show long pathname. ckuus5.c, 18 Feb 2002.
-
-Updated INTRO command to mention FTP, HTTP, and SSH. ckuus2.c, 18 Feb 2002.
-
-From Jeff: fixes for typos in GetLongPathName() code: ckuus[r4].c, 22 Feb 2002.
-
-From Jeff: net/auth updates: ckcnet.c, ckuath.c, 22 Feb 2002.
-
-Added -DUSE_FILE__CNT to NCR MPRAS targets, George Gilmer: makefile,
-24 Feb 2002.
-
-From Jeff: Add support for GetLongPathName() in Win95 and NT: ckcdeb.h,
-ckuus[r4].c, 24 Feb 2002.
-
-From Jeff: More fixes for FTP SIGINT, plus fix [M]PUT /MOVE. ckcftp.c,
-24 Feb 2002.
-
-Fixed an unguarded reference to inserver, gtword(): ckucmd.c, 24 Feb 2002.
-
-Adapted RETRIEVE for use with FTP connections; this one was missed when
-adapting GET, REGET, MOVE, etc. ckuus6.c, ckcftp.c, 24 Feb 2002.
-
-Added special COPYRIGHT command text for the free version of WIKSD.
-ckcmai.c, ckuusr.c, 24 Feb 2002.
-
-C-Kermit, when in CONNECT mode and given the <Esc-Char>U sequence, would
-unconditionally close the connection if it was a network connection. This
-is bad when Telnetting to a modem server. I added to code to prevent this
-in the RFC2117 TELNET COMPORT case but I'm not sure how to exend this to the
-general case (or whether it would be a good idea). ckucns.c, 24 Feb 2002.
-
-During file transfer, chktimo() calls ttgspd() for every packet, which clearly
-doesn't make sense on network connections, especially since on Telnet COMPORT
-connections it results in a network speed query for every packet. Rearranged
-the code so this happens only on true serial-port connections. ckcfn2.c,
-24 Feb 2002.
-
-From Jeff: Fix reversed ANSI/non-ANSI function declarations clauses in
-ckcftp.c, 26 Feb 2002.
-
-Changed Unix CONNECT module to call kstart() only when it has a chance of
-doing anything (i.e. a Kermit packet has been partially detected, or the
-packet start character just came in), rather than unconditionally on every
-incoming character. ckucns.c, 8 Mar 2002.
-
-FTP PUT /SERVER-RENAME:, /RENAME-TO:, /MOVE-TO: were sticky. Patch: In
-ckcftp.c, near the top of doftpput(), add the lines marked with "+":
-
- makestr(&filefile,NULL); /* No filename list file yet. */
-+ makestr(&srv_renam,NULL); /* Clear /SERVER-RENAME: */
-+ makestr(&snd_rename,NULL); /* PUT /RENAME */

-From Jeff, 4 Apr 2002:
- . More fixes for Telnet Com Port: ckuus4.c, ckudia.c, ckutio.c, ckcnet.c:
- . network connections will check for carrier detect if SET

-
-Chiaki Ishikawa reported that in Linux (two different kinds), if you choose
-hardware parity, CONNECT, then escape back, the speed can change. I tracked
-this down to the following statement in ttvt():
-
- tttvt.c_cflag &= ~(IGNPAR); /* Don't discard incoming bytes */
-
-Somehow execution of this statement corrupted the speed words of the termios
-struct, which are entirely separate words that are nowhere near the c_cflag
-member. Anyway, the statement is wrong; it should be:
-
- tttvt.c_cflag |= IGNPAR; /* Don't discard incoming bytes */
-
-Fixing it cured the problem; don't ask me why. ckutio.c, 9 Apr 2002.
-
-From Jeff:
- fixes the problem reported by robi@hastdeer.com.au. The request to
- enter server mode was received while we were entering server mode.
- But the server was waiting for the response to REQ_STOP sent to the
- client. Therefore, we weren't quite in server mode yet and the
- request to enter server mode was rejected. A check for the sstate
- value solves the problem. ckctel.c, 10 Apr 2002.
-
-Chiaki Ishikawa (CI) discovered the real cause for the speed changing problem.
-I was setting the IGNPAR bit in the wrong flag word: it should have been
-c_iflag instead of c_oflag, silly me. Fixed in ttvt() and ttpkt(): ckutio.c.
-I also did a thorough census of all the termio[s] flags to ensure each was
-applied to the right flag word -- they were, IGNPAR in the HWPARITY case was
-the only mistake. CI also discovered that the speed words in the Linux
-termios struct are not used at all -- the speeds are encoded in an
-undocumented field of c_cflag, which explains the problem. 10 Apr 2002.
-
-Any use of \{nnn} character notation in a macro definition, loop, or other
-braced block caused an "unbalanced braces" parse error. The backslash in this
-case is not quoting the open brace; it's introducing a balanced braced
-quantity. Special-cased in getncm(): ckuus5.c, 12 Apr 2002.
-
-The semantics of "if defined \v(xxx)" were changed in 8.0 to avoid obnoxious
-error messages when xxx was not a built-in variable (see notes of 19 Nov
-2000), such that "if defined \v(xxx)" would always succeed if there were such
-a variable, even if it had no value. The behavior that is documented in the
-book (and also in ckermit70.html) and that we had in versions 6 and 7, was
-that IF DEFINED \v(xxx) would fail if \v(xxx) was defined but had an empty
-value OR if it was not defined, and would succeed only if it was defined and
-had a value. Fixed in boolexp(): ckuus6.c, 12 Apr 2002.
-
-What about \function()s? IF DEF \fblah() presently succeeds if the function
-exists; you don't even have to give arguments. I think this behavior is more
-useful than if I required valid arguments and then evaluated the function --
-you can do that anyway with 'if not eq "\fxxx(a,b)" "" ...' Of course this
-argument applies to "if def \v(xxx)" too, except that the current behavior is
-consistent with the 7.0 behavior, so there is no need for a change.
-
-Kent Martin discovered that if a macro contains a LOCAL statement for a
-variable whose name is the same as, or a unique left substring of, the macro's
-name, then undefining the local variable makes the macro disappear:
-
- define DateDiff {
- echo {DateDiff(\%1) executing...}
- }
- define Kent {
- do DateDiff {2}
- local date
- assign date {}
- do DateDiff {3} <-- This fails (A)
- }
- do DateDiff {1}
- do Kent
- do DateDiff {4} <-- So does this (B)
-
-The first part of the problem is that "assign date {}" called delmac with
-exact=0, so delmac evidently deleted first macro whose name started with
-"date" -- and since the only one was DateDiff, that's the one that was
-deleted. Fixing this (change "delmac(vnp,0)" to "delmac(vnp,1)" in dodef())
-got us past A. The second part was making the same fix to the delmac()
-call in popclvl(). ckuus[56].c, 13 Apr 2002.
-
-The INPUT command ignored the parity setting, thus SET PARITY EVEN,
-INPUT 10 "login:" didn't work. Fixed in doinput(): ckuus4.c. Also fixed a
-bogus #ifdef COMMENT section that messed up the block structure of the module
-and therefore EMACS's indenting. 18 Apr 2002.

- . Add casts to args in tn_wait() calls: ckctel.c.
-
-SINIX-P 5.42 (Pyramid architecture) makefile target from Igor Sobrado.
-makefile (no source-code changes), 1 May 2002.
-
-From Jeff, 5 May 2002,
- . Fix some "unknown host" messages: ckcftp.c.
- . Add more casts to tnc_wait() calls: ckudia.c.
- . Improvements to SHOW SSH, SHOW GUI: ckuus3.c.
- . Fixes to SET COMMAND { WIDTH, HEIGHT }: ckuus3.c.
- . Updates to ck_ssl.[ch], ckctel.c, ckcnet.c.
-
-Fixed the erroneous setting of ssh_cas during switch parsing rather than
-after cmcfm() in setlin(): ckuus7.c, 5 May 2002.
-
-setlin() decomposition (2300 lines), Part One:
-
- . Copied a big chunk from the end of setlin(), beginning with net directory
- lookup, but only the network-specific and common parts, to a new routine,
- cx_net(), 900 lines.
-
- . Extracted many repetitious lines of error-message code from cx_net()
- to a new routine, cx_fail(). Error messages are stored in slmsg, and
- also printed but only if we were not called from a GUI dialog (and
- QUIET wasn't set, etc etc). Any adjutments in this policy can now be
- made in one place.
-
- . I put a call to cx_net() in setlin() just before all the code it replaced.
- It works for TELNET and SET HOST /TELNET.
-
- . Built with mkwatsol-k5k4ssl; after a couple fixes it builds OK and makes
- Kerberized connections OK.
-
- . Copied the serial-port and common parts of the setlin() post-cmcfm()
- code to another new routine, cx_serial(), about 275 lines. Fixed
- messages not to come out when called from GUI dialog, etc. Inserted
- a call to cx_serial() at the appropriate spot in setlin(). Tested
- serial connections on watsun with "set line /dev/ttyh6", works OK.
-
- . Removed all the code from setlin() that was copied to cx_*(). This slims
- setlin() down to 1120 lines. Tested regular Telnet, Kerberized Telnet, and
- serial connections again, all OK. The Unix version of the SSH command is
- OK too.
-
-setlin() deconstruction, Part Two:
-
-Now that we have the common network and serial connection pieces moved out of
-setlin(), we still need to move out the little code snippets for each network
-type that take place between command confirmation and the common code we just
-replaced. As far as I can tell, this needs doing only for SSH. The code
-labeled "Stash everything" copied to cx_ssh() but I didn't remove the original
-code since I can't test this. I think I'm done -- maybe I'm overlooking
-something but I don't know what... First we need to test the heck out of it
-in all command-line versions (K95 and C-Kermit). Then to use this from
-the GUI, see the calling sequences for cx_serial(), cx_net(), and cx_ssh():
-
- . For serial or TAPI connections, the GUI should call cx_serial().
- . For SSH connections, it should call cx_ssh() and then cx_net().
- . For all other network connections, just calls cx_net().
-
-ckuus7.c, Cinco de Mayo de 2002.
-
-New ckuus7.c from Jeff, 8 May 2002. Merge cx_ssh() into cx_net(). Also: I
-had made line[] an automatic variable, since the global line[] buffer is used
-by almost every parsing routine in C-Kermit to hold string fields between
-parsing and execution but Jeff says he found that some code somewhere depended
-on line[] containing the hostname after setlin() was finished.
-
-From Jeff, 10 May 2002:
- . Fix SET SSH STRICT-HOST-CHECKING parse: ckuus3.c.
- . Add prototypes for cx_net() and cx_serial(): ckuusr.h.
- . Add ANSI versions of cx_net() and cx_serial() declarations and supply a
- missing parameter in the cx_serial() invocation, change SSHCMD cx_net()
- invocation to new form.
-
-From Jeff, 16 May 2002:
- . ANSI strictness changes: ck_ssl.[ch]
- . New DIALER command: ckuusr.[ch]
- . Correction to how -0 turns off autodownload: ckuusy.c
- . Prototypes for GUI menu action functions: ckuusr.h.
- . Replace setting of GUI-action variables by function calls: ckuus[3457x].c
- . Fix FTP -z switch parsing: ckcftp.c.
- . Fix SET HOST testing of setlin() return code: ckuus3.c
-
-From Jeff, 18 May 2002:
- . Allow half-size GUI fonts: ckuus[35y].c.
-
-Fixed setguifont() to parse fractional font sizes and round to nearest half
-point. ckuus3.c, 18 May 2002.
-
-For GUI, wrote front ends for getyesno(), readtext(), and readpass():
-
- . uq_ok() prints text and gets Yes/No, OK/Cancel, or just OK response.
- This replaces getyesno() and can also be used for alert or help boxes.
-
- . uq_txt() prints text and gets a single text response. Replaces
- readtext() and readpass().
-
- . uq_mtxt() is like uq_txt() but allows multiple text fields. Replaces
- any combination of readtext() and readpass().
-
-Obviously the #ifdef KUI portions of the uq_blah() routines need filling in.
-ckuusr.h, ckuus3.c, 18 May 2002.
-
-Converted selected getyesno() calls to uq_ok(): ckcftp.c, ckuus3.c, ckuus6.c.
-Some were not converted because it was inappropriate, e.g. DELETE /ASK; others
-because they're in Jeff's code. The most interesting conversions are in the
-DIAL command when DIAL CONFIRMATION is ON. Here there is a dialog for each
-phone number asking if it's OK (ug_ok()) and if not, asking for a replacement
-(uq_txt()); seems to work fine in C-Kermit. All the candidates for uq_mtxt()
-are in Jeff's code. 18 May 2002.
-
-From Jeff: Convert remaining getyesno/readtext/readpass calls to uq_blah()
-so they can be GUI dialogs. ckuus[37].c, ckcftp.c, ckuath.c, ck_ssl.c,
-21 May 2002.
-
-Added KCD command = CD to symbolic directory name (EXEDIR, COMMON, APPDATA,
-TMPDIR, etc etc). ckuusr.h, ckuus[r25].c, 21 May 2002.
-
-From Jeff, 28 May 2002:
- . --title: commandline option: ckuusr.h, ckuusy.c
- . Fix some #includes, move some declarations: ckcfns.c
- . Change K95 version from Dev.00 to Beta.01
- . ASK[Q] /GUI: ckuus6.c.
- . Various GUI screen updates and #ifdefs: ckuus7.c
- . Add missing cx_net() calls to new setlin() for file SuperLAT..: ckuus7.c
- . Updated uq_*() routines for GUI dialogs: ckuus3.c.
-
-Added GETOK switches (/TIMEOUT for all; /POPUP and /GUI for K95G):
-ckuus6.c, 29 May 2002.
-
-Added HELP SET GUI text. ckuus2.c, 29 May 2002.
-
-From Jeff:
- . Another K95-specific #include for ckcfns.c.
- . More items for K95G Actions menu.
- . Change K95G Locus switching to call setlocus() rather than set variable.
- . Ditto for several other variables now settable from Actions menu.
- . Fix SET HOST /NET:SSH status code so IF SUCCESS works.
- . Fix SHOW SSH port-forwarding.
-ckcfns.c, ckuus[r367].c, ckcftp.c, ckcmai.c, 30 May 2002.
-
-Changed SET LOCUS to have a new value, ASK, corresponding to new autolocus
-value of 2, K95G only. Changed setlocus() to not do anything if the new and
-old loci are the same, otherwise to invoke a GUI dialog in K95G if autolocus
-is 2, and also to handle any text messages. Changed SHOW COMMAND to show ASK
-value for SET LOCUS. Rewrote HELP SET LOCUS. ckuusr.[ch], ckuus[23].c,
-ckcftp.c, 30 May 2002.
-
-Add a missing space to Locus popup, and fix Jeff's version of the code to
-compile in C-Kermit. ckuusr.c, 31 May 2002.
-
-From Jeff, for K95 GUI, 6 June 2002:
- . Force some GUI popups to be in foreground: ckuus3.c.
- . Fix SHOW TERM font display: ckuus5.c.
- . Update K95 version numbers and date (4 June 2002): ckcmai.c.
- . Add note about encrypted private keys vs scripts to HELP SET AUTH: ckuus2.c.
- . Fix SET HOST for DECnet: ckuus7.c.
-
---- K95 2.0 ---
-
-From Jeff, 7 June 2002:
- . Fix some #ifdefs for Unix builds (locus, dial, etc): ckuus7.c
- . Add gui_resize_scale_font() prototype: ckuus3.c
- . Add some missing SET GUI commands: ckuus3.c
- . Update version numbers: ckcmai.c
-
---- K95 2.0.1 ---
-
-From Jeff, 11 June 2002:
- . Conditionalize Locus-switching popup text for GUI/Console: ckuusr.c.
- . Fix the SRP_installed_as_server() function. The new API returns TRUE even
- if the SRP config and password files cannot be found. Went back to the old
- API. This bug affects C-Kermit 8 when built with SRP as well as 1.1.21
- through 2.0.1. Since iksdnt.exe has not been shipped yet I fixed it and
- uploaded a new non-beta build of it. ckuath.c.
-
-From Jeff, 12 June 2002:
- . Fix SSH AGENT ADD: ckuusr.c.
- . Fix --facename: option to not fail if name unknown: ckuusy.c.
- . Fixes for OpenSSL 0.9.7 and OpenBSD 3.1: ck_ssl.c.
- . Fix SET AUTH TLS VERIFY NO to prevent a dialog but still a warning if
- SET AUTH TLS VERBOSE ON is set: ck_ssl.c.
- . Fix FTP code to verify the hostname as specified by the user and not
- the hostname discovered by the reverse DNS lookup. For example,
- FTP OPEN kermit.columbia.edu
- should produce a dialog because that name is not in the certificate
- even though ftp.kermit.columbia.edu (the reverse DNS name) is: ckcftp.c.
-
-Add support for Solaris 9 and NetBSD 1.6. makefile, ckuver.h, ckcdeb.h,
-13 Jun 2002.
-
-Discovered that Solaris 9 wants to hide the members of struct FILE, and
-enforces this for 64-bit builds. They offer some functions like __fbufsize()
-to get the info, but not the info we need for reading escape sequences (the
-_cnt member). Let's hear it for political correctness. Created new solaris9g
-(32-bit) and solaris9g64 (64-bit) targets. Sorry, no arrow keys in 64-bit
-mode. Also no more direct access to sys_errlist[]; must use strerror().
-makefile, ckucmd.c, 13 Jun 2002.
-
-Added solaris9g+openssl+zlib+pam+shadow, which in turn required adding
-solaris2xg32+openssl+zlib+pam+shadow, needed for gcc 3.1 in which you have
-to specify 32-bit. Fails for some mysterious reason in link step
-(can't find libssl.so.0.9.6 even though it's there). makefile, 13 Jun 2002.
-
-Solaris 8 empty socket problems again -- tthang() times out, subsequent
-tcsetattr() calls do horrible things. Added a bandaid to ttclos(): don't
-call tcsetattr() any more if hangup timed out. ckutio.c, 14 June 2002.
-
-Gerry B reported the bandaid got us bit farther but Kermit still disappears.
-Added code to reassert the alarm signal handler, since it is likely that
-Solaris has become stricter about this since last time I looked. (Later
-Gerry reported back that this did the trick -- C-Kermit now exits normally
-and releases the lockfile). ttclos(): ckutio.c, 17 Jun 2002.
-
-If you use Kermit to copy a file to a destination file that already exists and
-is longer than the source file, the destination file is not truncated. I had
-mistakenly assumed that setting O_CREAT in the open() call in zcopy() would
-create a new copy of the file. Fixed by also setting O_TRUNC. ckufio.c,
-17 Jun 2002.
-
-Updated HELP INPUT and MINPUT text to explain 0 and -1 timeout values, and
-HELP DIAL to explain about entering CONNECT mode automatically. ckuus2.c,
-17 Jun 2002.
-
-Got rid of client-side "Press the X or E key to cancel" message when giving
-a REMOTE command if QUIET is set or if XFER DISPLAY is NONE. ckuus7.c,
-17 Jun 2002.
-
-From Jeff 25 Jun 2002:
- . Add SUN terminal type: ckuusr.h, ckuus[57].c.
- . Add GUI file transfer display: ckcker.h, ckuus[47x].c.
- . Changes to allow C-Kermit to build with OpenSSL 0.9.7. Current
- C-Kermit code is designed to compile with 0.9.6 and earlier. To
- compile with 0.9.7 you must specify -DOPENSSL_097. This avoids
- missing symbols in the DES library. The functions in OpenSSL were
- renamed in 0.9.7 to avoid link time conflicts with Kerberos 4.
- ckufio.c ck_crp.c ckuath.c ck_ssl.h ck_ssl.c, makefile.
-
-From Jeff 26 Jun 2002:
- . apparently the SSL Passphrase Callback function was not converted
- from readpass() to uq_txt()
- . FTP Authentication failure errors were not being reported to the
- user. So a failure would appear to be a successful completion
- unless FTP DEBUG was ON. Now the message is reported unless
- the QUIET flag is set.
-ck_ssl.c, ckcftp.c.
-
-SET TRANSFER MODE MANUAL didn't work for FTP; fixed in putfile() and getfile():
-ckcftp.c, 1 Jul 2002.
-
-Changed debug log for FTP to log "FTP SENT" and "FTP RECD" for protocol
-messages, just like we do for Telnet, to make it easy to grep them out of
-the log. ckcftp.c, 1 Jul 2002.
-
-In FTP MGET /UPDATE, equal times spuriously caused download. doftpget() was
-misinterpreting chkmodtime()'s return code. ckcftp.c, 3 Jul 2002.
-
-In FTP MGET /RECOVER, recovery is skipped if the local file is newer than
-the remote. This would seem to make sense, but when a download is
-interrupted, the partial file never gets the date of the remote file, so
-the partial file is always newer, and recovery never works. Fixed in
-recvrequest() by commenting out the date check. ckcftp.c, 3 Jul 2002.
-
-A better way to fix the previous problem is to always set the file date from
-the server and then only allow /RECOVER to work when the dates are equal.
-But that's not possible because MDTM is not implemented universally, and it
-conflicts with how Kermit currently works, namely that FTP DATES are OFF by
-default. Also, checking dates prevents [M]GET /RECOVER from working with
-files that were incompletely downloaded by some other FTP client.
-
-In FTP MGET /RECOVER <wildcard> <wildcard> ..., the first file in each group
-is always downloaded. Diagnosis: Kermit sends "TYPE A" prior to NLST (as it
-must). Then when it sends its first SIZE command, it's still in ASCII mode,
-so the server sends the "ASCII size" rather than the binary size, which does
-not agree with the size of the local file (which was downloaded in binary
-mode), so recovery is always attempted even when the files are identical. The
-TYPE A command is sent by initconn(). After the remote_files() call, we have
-to change the type back to the prevailing type before sending the first SIZE
-command. Fixed in cmdlinget() and doftpget(): ckcftp.c, 3 Jul 2002.
-
-In FTP MGET /EXCEPT:<pattern> used with SET XFER DISPLAY brief, files that
-are skipped just say ERROR instead of saying why they were skipped. Fixed
-in doftpget(): ckcftp.c, 3 Jul 2002.
-
-Added EXIT to top-level HELP text. ckuus2.c, 13 Jul 2002.
-
-Strip braces in REINPUT n {string}. ckuusr.c, 13 Jul 2002.
-
-Added /QUIET switch to ASK-class commands. This means not to print any error
-messages when an ASK-class command times out waiting for a response. Made
-sure that when a timeout occurs, the command fails. Also made sure the
-c-Kermit prompt doesn't write over the ASK prompt if ASK times out. Also
-fixed ASK, when it times out, not to return -9, which it did in one case,
-which causes a command-stack dump. ckuus[267].c, ckucmd.c, 13 Jul 2002.
-
-Fixed SET FILE INCOMPLETE help text, which said that both KEEP and AUTO were
-the default. ckuus2.c, 13 Jul 2002.
-
-If you SET FTP DEB ON and then turn it OFF, the MGET temp file is still kept.
-Fixed by getting rid of ftp_knf variable and using ftp_deb to control whether
-temp file is deleted (ftp_knf was being set from ftp_deb anyway, but then
-wasn't being reset by SET FTP DEB OFF). ckcftp.c, 13 Jul 2002.
-
-If an FTP transfer was in progress but the FTP connection drops and automatic
-locus switching is enabled, the locus does not change; thus (for example) a
-subsequent DELETE command makes Kermit send a REMOTE DELETE packet on stdout.
-Fixed in lostpeer(): ckcftp.c, 13 Jul 2002.
-
-For docs: FTP CD with no arg might not be accepted by the server; e.g. the
-Kermit FTP server says "501 Invalid number of arguments".
-
-The FTP module never handled SET INCOMPLETE. Fixed in doftprecv2(). ckcftp.c,
-13 Jul 2002.
-
-When FTP DATES is ON, we set an incoming file's date only if the file was
-received successfully. Changed the code to set the file's date even if it was
-received only partially (assuming we can get the date from server). ckcftp.c,
-13 Jul 2002.
-
-Suppose we were doing FTP MGET /UPDATE from a server directory of 100,000
-files. Kermit would send a SIZE command for every file unconditionally. On
-some connections, e.g. to the Red Hat Rawhide server, each one could take up
-to 30 seconds. That would be 3 million seconds = 34 days. Don't send a SIZE
-command during the selection phase unless a /SMALLER or /LARGER selector was
-given. Once the file is selected, send a SIZE command only if one hadn't been
-sent for that file already. ckcftp.c, 13 Jul 2002.
-
-Made [M]GET and [M]PUT /UPDATE switch imply FTP DATES ON, since they didn't
-work unless it was. ckcftp.c, 13 Jul 2002.
-
-Added FTP [M]GET /DATES-DIFFER, which is like /UPDATE except it selects files
-that are newer or older, rather than only newer. This allows updates from
-sources where files might be rolled back to earlier versions. It's a bit
-dangerous if you use it without knowing what it's for, since it allows older
-files to overwrite newer ones. (Code is also in place for [M]PUT
-/DATES-DIFFER, and it works, but I commented it out because it's either
-useless or dangerous since when uploading, you can't set the the file dates
-when they are arrive on the server.) ckcftp.c, 13 Jul 2002.
-
-Changed chkmodtime() to remember if MDTM fails on a particular connection
-because it's an unknown command (500, 502, or 202), and if so, not to ask
-again. ckcftp.c, 13 Jul 2002.
-
-With this last change, I think it's safe to change the default for FTP DATES
-from OFF to ON. ckcftp.c, 13 Jul 2002.
-
-Increased max number of /EXCEPT: patterns from 8 to 64 for file transfer (not
-necessarily for other things). This is now a compile-time symbol NSNDEXCEPT.
-ckcker.h, ckcmai.c, ckclib.c, ckcfns.c, ckcftp.c, ckuus[rx].c. 13 Jul 2002.
-
-Fixed FTP MGET to not send SIZE command when there is a name collision and
-FILE COLLISION is DISCARD, even if /SMALLER or /LARGER were also specified.
-ckcftp.c, 15 Jul 2002.
-
-MGET fails if no files were transferred, even if the reason is that no files
-met the selection critieria: /COLLISION:DISCARD, /UPDATE, /SMALLER, etc.
-Changed MGET to succeed in that case. domget(): ckcftp.c, 16 Jul 2002.
-
-Big problems with canceling MGET; Ctrl-C cancels the current file, but we
-don't break out of the file loop, we just go on to the next file. Worse, if
-we're executing a command file that has a series of MGETs, Ctrl-C doesn't
-break us out of the command file. Fixed by making failftprecv() and
-failftprecv2() "chain" to the main SIGINT handler, trap(). This is fine in
-Unix, but I'd be really surprised if it works in K95 so I put it in #ifndef
-OS2. Ditto for MPUT: Added the same treatment to failftpsend() and
-failftpsend2(). Ditto for cmdcancel(). To adapt to K95, search for "TEST ME
-IN K95" (5 places). ckcftp.c, 16 Jul 2002.
-
-Fixed previous fix to account for the fact that failftpblah() can be called
-not only upon Ctrl-C, but also if transfer interrupted with X or Z.
-ckcftp.c, 16 Jul 2002.
-
-Yesterday's fixes revealed another problem: Interrupt MGET with Ctrl-C, start
-another MGET, and the file list is total garbage. Diagnosis: secure_getc()
-and secure_getbyte() use internal static buffer pointers. The only way they
-ever get reset is when the data connection is closed by the server, so if you
-interrupt a GET, the pointers are not reset and the next network read (e.g. of
-an NLST response) returns whatever junk was lying around in the old buffer.
-ckcftp.c, 17 Jul 2002.
-
-FTP MGET temp file is kept only if FTP DEBUG is ON. Changed FTP module to
-also keep it if the regular debug log is active. ckcftp.c, 17 Jul 2002.
-
-Fixed version test in ckermit.ini: should be 6 digits, not 5. 17 Jul 2002.
-
-Changed C-Kermit version number to 8.0.205 so scripts can test for the
-recent changes. ckcmai.c, 18 Jul 2002.
-
----8.0.205---
-
-SET FILE COLLISION UPDATE would unset FTP DATES due to a typo in the recent
-changes. ckcftp.c, 21 Jul 2002.
-
-FTP [M]GET /DATES-DIFFER really should have been a collision option. Added
-this option (implemented for FTP only) to both SET FTP COLLISION and the
-FTP [M]GET /COLLISION: table, so this way if you have lots of [M]GETs, you
-don't have to put /DATES-DIFFER on each one. ckcker.h, ckcftp.c, 21 Jul 2002.
-
-"FTP MGET a* b* c*" would fail to get any c*'s if no b*'s existed.
-ckcftp.c, 21 Jul 2002.
-
-From Jeff, 22 Jul 2002:
- . Beginnings of Ann Arbor Ambassador terminal emulation for K95;
- ckuus[57].c, ckuusr.h.
- . Bump K95 version number to 2.0.2: ckcmai.c
-
-Added -DCK_PAM -DCK_SHADOW to all Solaris targets, 2.6 and above. makefile,
-23 Jul 2002.
-
-Discovered that CK_SCRIPTS path search for TAKE files was #ifdef'd out
-except for K95. Fixed in ckuusr.c, 25 Jul 2002.
-
-From Jeff: changes to support K95 italics: ckuus[57].c, 25 Jul 2002.
-
-Fixed path search for TAKE to not search the CK_SCRIPTS path if the filespec
-contains any directory or path parts. Added a new function to check for
-this: int hasnopath(filespec) in ckucmd.c: 26 Jul 2002.
-
-Update HP-UX build instructions from PeterE: makefile, 26 Jul 2002.
-
-Commented out "const" from struct pam_message declarations because it
-causes "initialization type mismatch" warnings. ckufio.c, 26 Jul 2002.
-
-Suppose you have a network directory containing a listing for host "foo":
-
- foo tcp/ip foo.bar.com
-
-Then in K95 you give a command "set host /network-type:ssh foo". This
-results in the directory lookup replacing the "ssh" network type with TCP/IP,
-and making a Telnet connection. Fix attempted at about line 8625 of ckuus7.c
-in cx_net(); needs testing in K95. 26 Jul 2002.
-
-FTP Password: prompt in Unix was not allowing editing. The code looked right;
-I put in some debugging and suddenly it worked. Took out the debugging and
-it still worked. Maybe I dreamed it. Anyway, I fixed the "FTP SENT" debug
-log entry to not record the password, and removed a redundant section above
-to log the same thing, but prior to any charset conversion. ckcftp.c,
-27 Jul 2002.
-
-From Jeff, 28 Jul 2002:
- . Fix typo in initxlist(): ckcmai.c.
- . Fix typo in Friday's set-host fix: ckuus7.c.
- . Move parsing of --height/width command-line args after prescan(): ckuusy.c.
-
-Added invisible top-level SITE and PASSIVE commands for FTP as a convenience
-for habituated FTP client users. ckuusr.[ch], ckcftp.c, 28 Jul 2002.
-
-A while back a user asked if it was possible to MGET a bunch of files from
-an FTP server and have them all appended to each other upon arrival. The
-obvious way to do this would have been:
-
- mget /collision:append /as-name:bigfile *.*
-
-But to make this work, I had to get rid of the "as-name must contain
-variables" check in the MGET parser. doftpget(): ckcftp.c, 28 Jul 2002.
-
-Verified that it was possible to do the same thing (GET a bunch of files
-and append them all into one result file) with Kermit protocol. It works
-fine but in this case there is no /COLLISION switch; you have to SET FILE
-COLLISION APPEND first. 30 Jul 2002.
-
-Changed COPY /APPEND to allow wild source to single destination file, e.g.
-"copy /append *.* bigfile". ckuus6.c, 30 Jul 2002.
-
-From Mark Berryman: a replacement for zchkpath(), the VMS routine that checks
-whether a file is in the current directory; the old one (that I wrote) was
-a hack that only worked sometimes. Martin Vorlaender verified Mark's code in
-the situation where mine was breaking (server running in captive account).
-ckvfio.c, 30 Jul 2002.
-
-PeterE reported a problem with SWITCH case labels that start with '#':
-The problem is that the SWITCH variable contents in this case happens to be
-a comment, e.g.:
-
- CMD(M)[_forward # Stand: 24.07.2002<CR>]
-
-so the GOTO target is null. The solution would be for SWITCH to put the GOTO
-(_FORWARD) target in quotes. But GOTO does not strip quotes or braces from
-around its target. Fixed in ckuusr.c, 30 Jul 2002.
-
-Fixed the SWITCH macro definition to put the _FORWARD target in quotes.
-ckuus5.c, 30 Jul 2002.
-
-PeterE also reported that an empty SWITCH case label did not work. There's no
-particular reason why it should, but after a brief look, it wasn't that hard
-so I did it. It required commenting out the check for empty labels and fixing
-the comparison in dogoto(). Now it's possible to read lines from a file and
-use each line as a SWITCH variable, with patterns as case labels, including an
-empty label to match empty lines, #* labels to match comment lines, etc.
-ckuus[r6].c, 30 Jul 2002.
-
-PeterE also reported the value of \%* acquiring a trailing blank when
-referenced inside a SWITCH statment. This happens because \%* is formed using
-\fjoin() on the \&_[] array based on its dimension, and at some point the
-dimension is spuriously increased by one. As a workaround, I made \fjoin()
-ignore trailing empty \&_[] array elements and oddly enough this also fixed
-the growing dimensions problem. The many script torture tests reveal no ill
-effects, so it seems like a keeper. ckuus4.c, 30 Jul 2002.
-
-Some of Peter's sample scripts made C-Kermit 8.0.201 dump core, but no more.
-
-Fixed "delete xxx" to print an error message and fail if if xxx does not exist.
-Ditto for when xxx is a directory. ckuus6.c, 30 Jul 2002.
-
-Patches to SSL modules from Jeff based on yesterday's advisory. ck_ssl.[ch],
-31 Jul 2002.
-
-Fixed some typos affecting the filename collision action during command-line
-FTP [M]GET. ckcftp.c, 31 Jul 2002.
-
-Fixed SHOW FTP to handle FTP COLLISION DATES-DIFFER. ckcftp.c, 31 Jul 2002.
-
-A while back someone pointed out that SET CONTROL UNPREFIX ALL and SET
-PREFIXING NONE gave different results. Fixed them to use the same code.
-Also made "set prefixing none" visible. ckuus3.c, 4 Aug 2002.
-
-Added SET CD HOME <path>, to let the user specify which directory is intended
-when "CD" or "KCD" is given by itself. This is because in Windows, some
-applications set up their own HOME environment variable that isn't necessarily
-where the user wants "cd" to go, but redefining HOME can interfere with the
-application (example: Windows EMACS). SET CD HOME was done by adding a myhome
-variable, initially a NULL pointer, and then changing homepath() to use it if
-it is set. zhome() is not affected. Also the homepath() prototype had been
-missing from header files. ckcmai.c, ckuusr.h, ckuus[2345].c, 4 Aug 2002.
-
-PeterE got another core dump with his SWITCH statement. Found a place where
-an out-of-bounds array reference could occur if the switch variable was
-empty. ckuus6.c, 5 Aug 2002.
-
-PeterE noticed that if the switch variable contained a comma, spurious matches
-could occur with the label pattern. The real problem turns out to be what
-happens when the SWITCH variable doesn't match any of the case labels and
-there is no DEFAULT label. Fixed by having dogoto() in the SWITCH (_FORWARD)
-case pop the command stack before returning failure, i.e. by moving the
-"if (stopflg) return(0);" statement down a few lines. ckuus6.c, 5 Aug 2002.
-
-PeterE noticed that a SWITCH case label of :* did not match an empty SWITCH
-variable. Fixed in doswitch(): ckuus6.c, 6 Aug 2002.
-
-In testing the previous fix, I found it only worked sometimes. Inspection
-of the debug log showed that a statement like:
-
- if (y == -3) s = "{}";
-
-was assigning "{" rather than "{}" to s. Replacing the string constant by a
-buffer containing the same string fixed it. The reason (guessed correctly by
-PeterE) was the following sequence:
-
- y = cmfld("Variable name","",&s,xxstring);
- if (y == -3) s = "{}";
- len = ckstrncpy(tmpbuf,brstrip(s),TMPBUFSIZ);
-
-brstrip() (by design and as documented) affects the string in place. But in
-this case the string is a constant, not data in a buffer, so all further uses
-of "{}" get the wrong string (at least in optimized builds). The only real
-cure is to change brstrip() to make a copy of its argument if it has to do
-anything to it. This will slow down some scripts, but it's too risky to
-leave it as it was. ckclib.c, 6 Aug 2002.
-
-The previous change required an audit of the C-Kermit code to make sure that
-no references to brstrip() depended the result buffer being persistent, or the
-result pointer indicating a position in the source buffer. Oops, it turns out
-that thousands of places rely on brstrip() working in place. Therefore the
-change had to be undone. There's no good way to write a dummy-proof brstrip();
-programmers either have be sure they're not calling it with a pointer to a
-string constant, or else they have to copy the result back to the right place
-each time. Better to leave it as it was and audit the code to fix any calls
-that refer to string constants (turns out there were only two). Restored the
-original fix to doswitch() (replacing the string constant by a buffer holding
-the same string), plus minor fixes to ckcftp.c, ckuus[r36].c, 6 Aug 2002.
-
-We need file dialogs in several situations in the K95 GUI. I added a "user
-query" routine for this, uq_file(), in ckuus3.c, filling it in only for Unix.
-Then I added code to call it from rcvfil() when (a) it's an autodownload, and
-(b) SET TERM AUTODOWNLOAD is ASK (I just added this option; it needs to be set
-to see it in action -- maybe it should be the default for KUI, in which case
-initialize "int autodl = ?" to TAD_ASK in ckcmai.c). Works fine, except of
-course it interferes with the file-transfer display, but that won't be a
-problem in K95G. ckuusr.h, ckuus[37].c, ckcfns.c, ckucns.c, 6 Aug 2002.
-
-Another place we need a file dialog is when Kermit is a URL interpreter. The
-problem is: how can we let the user decide whether Kermit should ask? There
-really isn't any way. Either it always asks or it never does. In this case I
-think it makes sense to always ask if it's KUI, otherwise never. I added the
-code for ftp: URLs to to doftprecv2(), which I tested successfully in Unix
-before putting it into #ifdef KUI..#endif. Also added code for http[s] to
-ckuusy.c in #ifdef KUI..#endif, not tested.
-
-Still need this added for K95G Actions->Capture. The clearest example is the
-FTP one. Just search for KUI in the FTP module.
-
-Some minor adjustments to yesterday's work, mainly just comments, plus
-generate the full pathname for the default file. ckuus3.c, ckcftp.c,
-7 Aug 2002.
-
-Note: for some reason cmofi() is not supplying the default value if user
-enters an empty name... (but that won't affect the Windows version).
-
-Added /USER: and /PASSWORD: switches to SET TCP { HTTP-PROXY, SOCKS-SERVER }.
-ckuus3.c, 7 Aug 2002.
-
-New 'uninstall' target from PeterE, works by having the 'install' target
-write an UNINSTALL shell script. makefile, 8 Aug 2002.
-
-Added some debugging statements to the VMS communications i/o module to try
-to track down a problem that occurs when the controlling terminal is a LAT
-device. ckvtio.c, 10 Aug 2002.
-
-Fixed the non-K95 uq_file() to respect the given default name, but still show
-the fully qualified absolute pathname for the default in the dialog. The
-reason to not use the fully qualifed name as the default in the cmxxx() calls
-is that this can easily result in a whole directory tree being created due to
-directory aliases, symlinks, etc. So when you get a file by referring to its
-URL (e.g. ftp://kermit.columbia.edu/kermit/READ.ME), uq_file() converts the
-READ.ME part to (e.g.) /home/fdc/tmp/READ.ME but gives just "READ.ME" as the
-default when parsing the name. This way the user knows where it will go and
-gets an opportunity to change it, and if the default is accepted, it goes into
-the current directory. uq_file(): ckuus3.c, 10 Aug 2002.
-
-Found the spot for calling uq_file() for kermit:// URL downloads. Added
-prefatory text to filename prompts for Kermit and FTP downloads. ckcfns.c,
-ckcftp.c, 10 Aug 2002.
-
-Now with kermit:// or ftp:// URL downloads there's no way to disable the
-prompting. I could easily make SET TERMINAL AUTODOWNLOAD ASK cover these
-cases too (even though "terminal" has nothing to do with FTP or URL
-downloads). OK, I did this, but now prompting is disabled by default.
-ckcftp.c, ckcfns.c. 10 Aug 2002.
-
-Enabled file prompting (adl_ask) by default in K95G, disabled it by default
-everywhere else. So now FTP and Kermit URL downloads as well as terminal-mode
-Kermit (but not Zmodem) downloads are prompted for if TERMINAL AUTODOWNLOAD is
-ASK, which is it by default only in K95G. But this will happen only if
-uq_file() is filled in for K95G; otherwise everything should work as before.
-ckcmai.c, 10 Aug 2002.
-
-Notes:
- . Need a better command to control this.
- . FTP URL downloads are almost instantaneous, whereas Kermit URL downloads
- take a really long time to set up (logging in takes at least 10 seconds).
-
-From Jeff, 13 Aug 2002:
- . Increase K95 version to 2.1.0: ckcmai.c.
- . SET TCP { HTTP-PROXY, SOCKS-SERVER } /USER: /PASSWORD: actions: ckuus3.c.
-
-From PeterE: a new install target that's only about half as a big as the
-previous one, yet still generates an UNINSTALL script. makefile, 13 Aug 2002.
-
-Vace wanted to be able to give the FTP client an offset for the server time,
-in case the server's time (or timezone) is set incorrectly. I added this by
-building on all the date/time parsing/arithmetic code -- notably delta times
--- that was done for C-Kermit 8.0. The new command is SET FTP
-SERVER-TIME-OFFSET delta-time; shows up in SHOW FTP and HELP SET FTP.
-ckcftp.c, 13 Aug 2002.
-
-Fixed HELP ASK and HELP GETOK text. ckuus2.c, 14 Aug 2002.
-
-Fixed GETOK to accept /GUI switch even in K95.EXE and C-Kermit, just like ASK
-does (in which case, it just ignores it). ckuus6.c, 14 Aug 2002.
-
-SET XFER CHAR TRANSPARENT no longer disables character-set translation because
-file-scanning turns it back on. The "new way" to disable character-set
-translation is SET XFER TRANSLATION OFF. This needlessly confuses users who
-expect the old way to still work. So I fixed SET XFER CHAR TRANSPARENT to set
-XFER TRANSLATION OFF, and SET XFER CHAR anything-else to set it back ON.
-ckuus3.c, 15 Aug 2002.
-
-Fixed SET TERM AUTODOWNLOAD { ON, OFF } to turn off the ASK flag (adl_ask).
-ckuus7.c, 16 Aug 2002.
-
-Added FEAT query to FTP client from draft-ietf-ftpext-mlst-13.txt. FEAT is
-sent along with REST 0, MODE S, and STRU F if /NOINIT is not included in the
-FTP OPEN command. Parsing the FEAT result is handled by turning the "auth"
-argument to getreply() into a function code: GRF_AUTH to parse AUTH reply;
-GRF_FEAT to parse FEAT reply. For GRF_FEAT, getreply() fills in a flag array,
-sfttab[] (server feature table); sfttab[0] > 0 means server responded to the
-FEAT query, in which case individual elements are set > 0 for each supported
-feature. ckcftp.c, 18 Aug 2002.
-
-If server sends a feature list, display it if FTP DEBUG is on, then set mdtmok
-and sizeok (the flags that say whether it's OK to send MDTM and SIZE commands)
-accordingly. If user gives an [M]PUT /RECOVER command and server has
-announced it doesn't support REST, print a warning but try anyway (maybe
-change this later). Responses about other features that we use such as AUTH
-and PBSZ are ignored for now -- i.e. we try them anyway. And of course
-responses for features we don't care about (LANG, TVFS, PROT) are ignored.
-ckcftp.c, 18 Aug 2002.
-
-If the server says it supports MLST, use MLSD instead of NLST to get the file
-list. This is done in remote_files() with some simple string-twiddling. Then
-replace the relevant (but not all) SIZE commands with code to first check if
-we already got the size from the MLSD response and use that instead rather
-than asking again. Same deal for MDTM. ckcftp.c, 18 Aug 2002.
-
-Checked that this works when giving pathnames in the MGET filespec. Checked
-to make sure everything works as before with servers that don't support FEAT
-or MLSD. Checked to make sure FTP OPEN blah /NOINIT worked with servers that
-do support FEAT and MLSD. Checked that FTP CHECK works. It's all OK.
-
-Tested only with Ipswitch server; need to find and test with others.
-
-The stack of temp files needed for MGET /RECURSIVE is annoying because what
-if we run out of file descriptors... But the spec doesn't provide a way to
-request a recursive listing.
-
-Supplied a missing comma in HELP SET CD text. ckuus2.c, 19 Aug 2002.
-
-Generalized parsing of MLST/MLSD file facts and values. Got file type from
-server and had MGET skip non-regular files. ckcftp.c, 19 Aug 2002.
-
-Kirk Turner-Rustin <ktrustin@owu.edu> reported that if Unix C-Kermit has a SET
-HOST PTY connection (e.g. SSH) open, local window size changes are not
-propogated through the connection to the host. I imagine that must be because
-the SIGWINCH signal is caught by Kermit and its children don't see it; maybe
-if I pass it along to the child fork, all will be OK. Began by exporting
-"slavepid" from the pty module and changing its name to pty_fork_pid. Moved
-the SIGWINCH handler, winchh(), from ckctel.c to ckutio.c. Armed it from Unix
-sysinit() so it's always armed. This way window changes affect Unix C-Kermit
-no matter what mode it's in: tt_rows, tt_cols, cmd_rows, and cmd_cols are all
-kept in sync. Then if we're not in remote mode (i.e. we have a ttyfd), we
-call tn_snaws() and rlog_snaws() (which should be ok since they return right
-away if the appropriate kind of connection is not open) and then if
-(pty_fork_pid > -1), a SIGWINCH signal is sent to it. ckupty.c, ckctel.c,
-ckutio.c, 20 Aug 2002.
-
-All this works fine except the PTY part; in other words, the original problem
-is not fixed. The "kill(pty_fork_pid,SIGWINCH)" call executes without error
-but has no effect because the size of the PTY never changed. To make this
-work I had to add an ioctl() to change the size of the PTY before sending it
-the SIGWINCH. Compiles and works ok on Linux and Solaris; Kirk also confirmed
-it for AIX 4.3.3. ckutio.c, 20 Aug 2002.
-
-Fixed xlookup() to work for uppercase keywords. ckucmd.c, 20 Aug 2002.
-
-Fixed FTP parsefeat() and parsefacts() to use xlookup() instead of lookup(),
-since abbreviated keywords are not allowed. ckcftp.c, 20 Aug 2002.
-
-Adjusted some lines from yesterday's window-size code for platforms I hadn't
-tried yet. ckutio.c, 21 Aug 2002.
-
-EXIT from K95 when it has an FTP connection open and it pops up the
-Locus dialog. Made it not do this if it knows it's in the act of EXITing.
-ckuus[rx].c, 22 Aug 2002.
-
-In K95, FTP GET in ASCII mode results in a file with Unix line terminators
-even though the protocol is correct:
-
- RETR smjulie.txt
- 150 Opening ASCII mode data connection for smjulie.txt (1878 bytes).
-
-The source file is a regular Unix text file with LF at the end of each line.
-It's incredible that nobody noticed this before. It only came to light when
-somebody tried to open a downloaded text file with Notepad, which doesn't
-handle Unix-format files (Wordpad and Emacs have no problems with them). The
-problem was in doftprecv2() in the FTT_ASC section. There was no conditional
-code for Unix vs Windows. In all cases, the code discarded incoming CR's in
-ASCII mode. I put the CR-discarding code in #ifdef UNIX..#endif. ckcftp.c,
-22 Aug 2002.
-
-Removed super-verbose debugging from gtword(): ckucmd.c, 23 Aug 2002.
-
-Gregory Bond reported a problem with "if defined \$(BLAH) ..." inside of a
-SWITCH statement. It wasn't really the SWITCH that was doing it, it was the
-fact that he had enclosed the SWITCH case in braces, which made it an
-"immediate macro" (XXMACRO). The XXMACRO code parsed the macro definition
-(the part inside the braces) with cmtxt(...,xxstring), which should have been
-cmtxt(...,NULL) to defer the evaluation of the interior of the macro until it
-was executed. This is better illustrated with the following example:
-
- { echo START, for \%i 1 3 1 { echo \%i }, echo STOP }
-
-which totally fell on its face prior to the fix. Also fixed ?-help for
-immediate macros, which was broken too. ckuusr.c, 23 Aug 2002.
-
-RFC959 says STOU does not take an argument. But every FTP server I've
-encountered but one accepts the arg and constructs the unique name from it,
-which is better than making up a totally random name for the file, which is
-what RFC959 calls for. Especially because there is no way for the client to
-find out the name chosen by the server (because RFC 959 and 1123 are
-contradictory, plus no servers follow either one of them for this anyway). So
-we try STOU with the argument first, which works with most servers, and if it
-fails, we retry it without the arg, for the benefit of the one picky server
-that is not "liberal in what it accepts" UNLESS the first STOU got a 502 code
-("not implemented") which means STOU is not accepted, period (which happens
-with ProFTPD). ckcftp.c, 25 Aug 2002.
-
-Added SET FTP ANONYMOUS-PASSWORD (plus help text and show value). ckcftp.c,
-25 Aug 2002.
-
-Made FTP command "not available" if NOFTP is defined. ckuusr.c, 25 Aug 2002.
-
-Forced client to send a TYPE command upon initial connection, since given
-the variable quality of FTP servers, it's not safe to assume the server is
-in ASCII or any other particular mode. ckcftp.c, 25 Aug 2002.
-
-SET FTP CHARACTER-SET-TRANSLATION ON is completely broken in K95, although it
-works fine in C-Kermit. Furthermore it is broken in both the GUI and Console
-versions, so it's not a Unicode vs OEM console-character-set issue.
-
-Added Concurrent PowerMAX OS target from Tom Horsley. makefile, ckuver.h,
-27 Aug 2002.
-
-Minor fixes to FTP module from Jeff. ckcftp.c, 27 Aug 2002.
-
-New Makefile target for Mac OS X 10.2, needs -DNDSYSERRLIST added, from
-William Bader. 2 Sep 2002.
-
-SET OPT DIR /DOTFILES didn't work for server listings. A few years ago when
-I front-ended zxpand() with nzxpand(), I missed a couple places where
-traverse() needed to refer to xmatchdot (nzxpand's argument flag) rather than
-global matchdot. Fixed in traverse(): ckufio.c, 2 Sep 2002.
-
-From Jeff, 4 Sep 2002:
- . setautodl(x) -> setautodl(x,y): ckuusr.h, ckuus[7y].c
- . Add another parameter to popup_readblah(): ckuus6.c
- . Sort out some confusion in scanfile() where a parameter was also used as a
- local flag. ckuusx.c.
- . Protect restoring of saved terminal idle parameters with a flag that says
- they were actually saved. ckuusr.c.
- . Rework uq_text() and uq_mtxt(). ckuus3.c.
- . Fix FTP charset translation for little-endian hardware: ckcftp.c.
-
-The latter still doesn't work in Linux:
-
- (/home/fdc/kermit/) C-Kermit>set ftp server-character-set latin1-iso
- (/home/fdc/kermit/) C-Kermit>set file character-set utf8
- (/home/fdc/kermit/) C-Kermit>get latin1.txt
-
-Results in "????????: file not found". But it works fine on the Sun.
-
-Jeff's patch removed a little-endian byte-swap (LEBS) from doftpsend2(). But
-the real problem was that LEBS was not being done consistently throughout the
-module. There were similar xgnbyte()/xpnbyte() loops elsewhere in the code,
-and all of them needed to work the same way. Undoing Jeff's fix and then
-adding the LEBS to the loop in getreply() makes downloads work right, but the
-messages are still messed up (they come out in Chinese :-) Begin by moving all
-byte-swapping operations that occur in ckcftp.c itself into a new function,
-bytswap(). It's either right to do it all the time, or to do it never; this
-way we can turn it on and off in one place.
-
-xp/gnbyte() include behavior that depends on what Kermit is doing: W_SEND,
-etc. xpnbyte() tests W_KERMIT, which is a combination of W_SEND, W_RECV, etc.
-Defined a new symbol W_XFER, which is like W_KERMIT but includes W_FTP. These
-are all the "whats" in which character sets might need to be converted.
-Changed the W_KERMIT reference in xpnbyte() to W_XFER. Fixed the inderminate
-"what" state after an FTP command by moving "what = W_COMMAND;" from before
-the main parse loop to inside it (this didn't matter before the addition of
-FTP but now it does). ckcker.h, ckcftp.c, ckuus5.c, 6 Sep 2002.
-
-Finally I changed xlatec() to be consistent with all the other xgnbyte() /
-xpnbyte() usage throughout the FTP module and, poof, everything worked in
-Linux (and still works on the Sun). We still need some work in Windows (where
-the file character-set is not necessarily the console character set for
-messages) but we can tackle that next. ckcftp.c, 6 Sep 2002.
-
-Checking yesterday's work:
-
-Kermit file transfers with charset translation work fine in both directions.
-
-FTP GET with charset translation works fine on both BE and LE
-
-Fixed a typo in yesterday's changes that made FTP PUT with charset translation
-always upload 0-length files. ckcftp.c, 7 Sep 2002.
-
-FTP PUT (after the typo was fixed) with charset translation works fine on BE,
-but on LE the message comes out in Chinese and the resulting file gets ? or
-nothing for all for the accented letters:
-
- FTP... Kermit
- Up Dn Up Dn Term
- BE OK OK OK OK xx
- LE no OK OK OK xx
-
-xx = C-Kermit CONNECT mode with translation doesn't seem to do anything, not
-only in today's code, but also in the 8.0 release version: "set term char
-latin1 utf8" -- SHOW CHAR shows the right stuff, but no translation is done.
-Ditto for the 7.0 release. That can't be right...
-
-But one problem at a time -- what's wrong with LE FTP uploads? Note that
-XLATE works on the same machine, so it's obviously confusion in xgnbyte()
-about "what". Suppose we make xgnbyte() ALWAYS return bytes in BE order.
-This makes sense because xgnbyte() is almost always used to feed xpnbyte(),
-and xpnbyte() requires its bytes to come in BE order. This means that all
-code that uses xgnbyte()/xpnbyte() loops can be simplifed, which I did for
-the FTP module. ckcfns.c, ckcftp.c, 7 Sep 2002.
-
-Of course Kermit protocol uses xgnbyte() too, but only for filling
-packets, and packets never contain UCS2 and even if they did, it would have
-to be big-endian, so no changes needed for getpkt(). Now we have:
-
- FTP... Kermit
- Up Dn Up Dn
- BE OK OK OK OK
- LE OK OK OK OK
-
-Now let's look at the remaining xgnbyte() calls in the rest of the code:
-
-ckuus4.c:
- xlate() uses it of course. I simplified the general-case loop.
- Works OK on both Sun and Linux.
-
-ckuus6.c:
- typegetline() uses it. I commented out the byte swap. Seems OK.
-
-Built and tested on Linux, Solaris, and SunOS. I'm sure I must have broken
-something, but the main things are better than they were. Kermit and FTP
-transfers need testing in K95, as well as the TYPE command (there's a bunch of
-special K95 code in there). C-Kermit charset translation during CONNECT is
-still broken, or else I forgot how to use it, but that's a separate issue
-since xgnbyte()/xpnbyte() are not involved. And we still need to do something
-in FTP getreply() for K95 to convert messages to the console character set for
-display, rather than the file character set (should be trivial). Also there's
-still a lot of extra debugging and commented-out junk in ckcftp.c to be
-cleaned up after more testing.
-
-During yesterday's testing, I noticed that REMOTE SET { FILE, XFER }
-CHARACTER-SET didn't work. The server accepted these commands but they didn't
-seem to do anything. In fact, they did work, but they were undone later by
-code in sfile() that restored the global settings in case they had been
-temporarily overridden by autoswitching or whatever. The solution is to
-"unsave" the saved values whenever a global setting is performed explicitly.
-Tested successfully against Sun and Linux servers. Also the server end of
-REMOTE SET needed updating for Unicode. ckcfn[s3].c, ckuus3.c, 8 Sep 2002.
-
-Cleaned commented-out cruft and extra debugging from ckcftp.c. 8 Sep 2002.
-
-Kermit autodownload with ASK file dialog: if user supplied an absolute
-pathname, it was treated like a relative one. Fixed the invocation of
-uq_file() in rcvfil() to temporarily override the RECEIVE PATHNAMES setting.
-ckcfns.c, 10 Sep 2002.
-
-Added SET TERMINAL ROLL KEYSTROKES { SEND, RESTORE-AND-SEND, IGNORE }, parse
-only. Needs implementation (search for tt_rkeys and rollkeytab in ckuus7.c).
-ckuusr.h, ckuus[27].c, 10 Sep 2002.
-
-If FILE INCOMPLETE is DISCARD and a file is being received by IKSD but IKSD
-gets a Telnet LOGOUT command, the partial file is not deleted. In fact this
-happens any time doexit() is called for any reason during file reception,
-e.g. because of SIGHUP. Added code to doclean() to check if a download
-output file was open, and if so, to delete it after closing it if keep==0.
-ckuusx.c, 10 Sep 2002.
-
-Added a brief one-line message after remote-mode file transfer saying
-what (or how many) file(s) were transferred, where they went, and whether
-the transfer was successful -- kind of an automatic WHERE command, useful
-with autodownloads so you know what happened. ckcpro.w, 11 Sep 2002.
-
-The Unix and VMS C-Kermit CONNECT modules have botched remote-charset to
-local-UTF8 translation ever since the Unicode was first added in v7.0. Fixed
-in ckucns.c, ckucon.c, ckvcon.c, 11 Sep 2002.
-
-On to pattern-matching... The matchdot business should apply only for (Unix)
-filename matching, not for general string matching. Fixed in ckmatch():
-ckclib.c, 11 Sep 2002.
-
-A bigger problem occurs in filename matching. Somehow the dirsep == fence
-business interferes with matching {foo,bar,baz} segments. For example, I have
-a filename "foo" and I want to match it with the pattern "{foo,bar}". Somehow
-the segment pattern becomes "*/foo" and doesn't match the string. Where does
-the '/' get tacked on? I don't even know how to explain this, but the short
-story was that ckmatch(), under certain circumstances, would back up to before
-the beginning of the filename string, which just happened to contain a "/"
-(and before that a ".") because of who was calling it. Obviously this is not
-how to write a pattern matching function... Ensuring that it never backs up
-beyond the beginning of a string fixed the immediate problem and does not seem
-to have broken any other matching scenarios (I have 150 of them in my test
-script). ckclib.c, 11 Sep 2002.
-
-There's still a problem though. Suppose the a client sends "dir {{.*,*}}" to
-a server. This asks for a directory listing of all files that begin with
-dot as well as all files. Still doesn't work because we don't normally show
-dot-files, but in this case it SHOULD work because ".*" was explicitly
-requested. Staring at the ckmatch() code revealed how to fix this, and I did,
-but that was only half the problem. The other half was that the list of
-files being fed to ckmatch() did not include the dotfiles in the first place.
-The cure here is to change nzxpand() to prescan the pattern to see if it
-includes a leading dot, and if so to set the "xmatchdot" flag itself, even
-if it wasn't set by the caller. ckclib.c, ckufio.c, 11 Sep 2002.
-
-Now that {foo,bar,...} patterns work better, I added a quick hack to the
-DIRECTORY command to allow multiple filespecs to be given, in which case we
-combine them into a {file1,file2,...} pattern before calling nzxpand(). Works
-fine but it's a hack because you don't get file lists upon "?" in the second
-and subsequent filespec fields, but I doubt anyone will notice. So now,
-finally, people can do "dir .* *" like they do in Unix (except with ls) to get
-a listing of all files in a directory without having to know about or use the
-/DOTFILES switch. This was NOT done for the server end of RDIR because of
-ambiguity of spaces as separators versus filename characters.) domydir():
-ckuus6.c, ckuus[r2].c, 11 Sep 2002.
-
-Added a CONTINUE command. In a script, this does whatever CONTINUE did before
-(e.g. in a FOR or WHILE loop). At the prompt, it calls popclvl(), which gives
-a more natural way to continue a script that has "shelled out" to the prompt.
-ckuusr.[ch], 11 Sep 2002.
-
-Added help text for CONTINUE. ckuus2.c, 12 Sep 2002.
-
-From Jeff, 16 Sep 2002:
- . SET TERM ROLL KEYSTROKES for K95: ckuusr.h, ckuus7.c
- . Remove the doexit() call from the Telnet TELOPT_LOGOUT handler: ckctel.c
-
-Fixed an FTP debug message to be consistent with Kermit ones.
-ckcftp.c, 16 Sep 2002.
-
-Added SET/SHOW TRANSFER REPORT to turn the post-transfer report off and on.
-ckuusr.h, ckuus[234].c, 16 Sep 2002.
-
-Fixed Solaris (and maybe some other SVORPOSIX builds) to find out their full
-hostname rather than just short form (e.g. watsol.cc.columbia.edu rather than
-just watsol). ckhost(): ckuusx.c, 16 Sep 2002.
-
-"cat somefile | kermit -Ts -" is supposed to send stdin in text mode, but
-K95's file transfer display reports BINARY. Looked at C-Kermit code; it seems
-fine. Looked at packet and debug logs; C-Kermit was indeed sending in text
-mode and announcing it correctly. K95 gattr() is doing the right thing:
-
- gattr file type[AMJ]=3
- gattr attribute A=text=0
- gattr sets tcharset TC_TRANSP[A]
-
-Same thing happens when C-Kermit is receiving. Yet when I send an actual
-file, rather than stdin, it's received in text mode. The only difference is
-that stdin does not have a Length attribute in its A-packet, so in this case
-the receiver skips any calls to screen() that show the length or percent done.
-Aha, so maybe it's just a display problem -- scrft() is not being called to
-repaint the file type if the size was not known. Fixed in opena() by
-removing the IF clause from "if (fsize > -1L) xxscreen(SCR_FS,0,fsize,"");".
-ckcfn3.c, 18 Sep 2002.
-
-K95 user has a listfile containing some regular filenames and then some
-filenames that include paths and has all kinds of problems with MGET /LISTFILE
-(pieces of different names concatenated to each other, etc). Setting up the
-same scenario here, I don't see the same problems but I do see "Refused: Name"
-when we go to get a path/name file. This happens because (a) we had already
-got a top-level file with a certain name, (b) a file in a subdirectory has the
-same name, (c) we are stripping the path before calling zchki(), and (d)
-FTP COLLISION is set to DISCARD. How do we make FTP not strip the path?
-
-This is an interesting question... The answer depends on where the user
-wants the file to go. Normally if you tell an FTP client to "get foo/bar",
-you want the file "bar" to be downloaded to the current directory.
-
-Anyway, it turns out the FTP module uses paths locally during MGET only if
-/RECURSIVE was specified. So:
-
- mget /listfile:blah /recursive
-
-should have made this work, but it didn't because in the /LISTFILE case,
-we have effectively turned an MGET into a series of GETs, where the code to
-check whether to strip the path didn't check the recursive flag because how
-could a GET (as opposed to an MGET) be recursive? Adding this exception to
-the if-condition got us a bit farther but now when we try to open the output
-file in doftprecv2(), zopeno() fails because the name contains a dirsep.
-We have to call zmkdir() first but that wasn't happening because some other
-flag wasn't set right in this case. Finally zmkdir was called, but with
-the wrong string. After fixing that, it works. Now we should be able
-to use /RECURSIVE to force the pathname to be used on the local end.
-ckcftp.c, 19 Sep 2002.
-
-Checked FTP filename conversion issues. FTP FILENAMES AUTO is supposed to
-mean LITERAL if "wearealike" OR server is UNIX or Windows, otherwise
-CONVERTED, but there were places where this rule was not applied consistently,
-fixed now. ckcftp.c, 21 Sep 2002.
-
-Added SET FTP DISPLAY, which is like SET TRANSFER DISPLAY but applies only to
-FTP, mainly because I tended to type it all the time. Now if you have dual
-sessions, each session can have its own transfer display style. ckcftp.c,
-ckuusr.h, ckuus[347].c, 21 Sep 2002.
-
-Back to FTP MLSD. We're supposed to match the pattern locally, not rely on
-the server to filter its list according to the client's pattern. Thus we must
-also allow an empty argument to MGET and must not send a filespec with MLSD.
-Actually this is tricky -- how is the client supposed to know whether to send
-a filespec. For example, if the user's command is "mget foo*bar", and the
-server supports MLSD, then what should the client do? The client does not
-know the wildcard syntax on the server, so for all the client knows, this
-might be a valid directory name, in which case it should be sent. On the
-other hand, the user might intend it as a wildcard, in which case it should
-NOT be sent. But the FTP client can't read the user's mind. This is another
-serious flaw in the Elz/Hethmon draft. Anyway, I got the local matching
-business working for MLSD as long as the user's MGET arg is really a pattern
-and not a directory name. To be continued... ckcftp.c, 21 Sep 2002.
-
-Added FTP { ENABLE, DISABLE } { FEAT, MLST }. If we always send FEAT, we
-usually get a complaint. If we send FEAT and MLST is negotiated, there is a
-good chance it is misimplemented or will have undesirable side effects, such
-as sending huge file lists. NOTE: /NOINIT on the FTP OPEN command also
-disables both of these. ckcftp.c, 22 Sep 2002.
-
-Fixed mkstemp() code in FTP remote_files(). mktemp() does not open the file,
-mkstemp() does open it; previously we had been opening it again and never
-closing the first instance so every MGET would create another open file
-descriptor. ckcftp.c, 22 Sep 2002.
-
-Added debug messages for temp-file creation and lines read from the temp file.
-ckcftp.c, 22 Sep 2002.
-
-Eliminated sending of some extraneous TYPE commands, but there's still room
-for improvement. ckcftp.c, 22 Sep 2002.
-
-Moved definition of build date to top of ckcmai.c. 22 Sep 2002.
-
-Added recursion to MGET with MLSD... It's all done in remote_files().
-Temp-file pointers are on a stack (max size 128). When parsing MLSD lines
-from the temp file and we see "type=dir", we create the local directory by
-calling zmkdir(), change to the remote by sending CWD, increment the depth,
-and call ourselves. When reading from a temp file, upon EOF we close and
-dispose of the temp file, return -3 if currently at top level, otherwise we
-free the tmpfile name, decrement the depth, send CDUP to the server, "cd .."
-locally, and go back and read the next line from the previous but now current
-temp file. Conceptually simple but needed hours of debugging -- what must
-be static, what must be on the stack... Seems OK now but still needs some
-heavy testing. ckcftp.c, 22 Sep 2002.
-
-Added FTP { ENABLE, DISABLE } { SIZE, MDTM } and add help text for FTP
-ENABLE and DISABLE. ckcftp.c, 23 Sep 2002.
-
-Don't allow restart if SIZE disabled. ckcftp.c, 23 Sep 2002.
-
-Make sure all implicit SIZE commands are surpressed if SIZE disabled.
-ckcftp.c, 23 Sep 2002.
-
-If an explicit FTP MODTIME command is sent when MDTM is DISABLED, and it
-succeeds, re-ENABLE MDTM. Ditto for SIZE. ckcftp.c, 23 Sep 2002.
-
-If an explicit FTP FEATURES command is sent during an FTP session, redo the
-features database from it. ckcftp.c, 23 Sep 2002.
-
-After further discussion with Robert Elz, I realized I had to expose the
-underlying MGET mechanisms to the user; the draft isn't going to change, and
-the new spec will result in undesirable effects if the client tries to "do the
-right thing" by magic in all situations; thus the user must have some new
-controls:
-
- MGET [ /MLST, /NLST, /MATCH:xxx ] [ filespec [ filespec [ ... ] ] ]
-
-These switches let the user force the use of MLSD or NLST when there's a
-choice, and to force local use of a pattern rather than sending it to the
-server, and even to send a directory name to the server at the same time as
-specifying a pattern for local matching, and of course by default we try to do
-the right thing in all scenarios. Symbols only; not coded yet. ckuusr.h,
-23 Sep 2002.
-
-Added the three new switches to MGET, plus /MLST is an invisible synonym for
-/MLSD. If /NLST or /MLSD is given it, it forces the corresponding FTP protocol
-directive. ckcftp.c, 25 Sep 2002.
-
-Now for the tricky part: now we have two separate concepts for what to send to
-the server: a filename or wildcard to be interpreted by the server (NLST only)
-or a directory from which to get a list of all the files (NLST or MLSD),
-possibly together with a pattern to be used by the client to match filenames
-returned by the server. This required giving remote_files() an additional
-argument. Now it uses "pattern" (if any) strictly for local pattern matching
-(because now it is the /MATCH: switch argument, not the MGET filespec), and
-"arg" (the MGET filespec) is what it sends to the server, maybe (see the
-comments in the code for the actual details); either or both these can be
-null. ckcftp.c, 25 Sep 2002.
-
-Discovered that "mget foo", where foo is a directory name, never worked.
-Fixed in remote_files(): ckcftp.c, 25 Sep 2002.
-
-Going through every combination of NLST, MLSD, /MATCH:, and MGET arg and
-debugging each case until OK... Then also with the panix.com NetBSD server
-(lukemftpd 1.0) which also supports MLSD.... 11 test cases all debugged and
-tested OK. ckcftp.c, 26 Sep 2002.
-
-Added /NODOTFILES switch to FTP MGET, to control what happens with dot-files
-if the server includes their names in the list (as lukemftpd does). There's
-no point in adding a /DOTFILES switch because what could it possibly do?
-ckcftp.c, 26 Sep 2002.
-
-Changed a bunch of "skipthis++" to "continue" in doftpget(), to avoid
-error messages when skipping files that user said she wanted to skip.
-ckcftp.c, 26 Sep 2002.
-
-Added help text for the new MGET switches. ckcftp.c, 26 Sep 2002.
-
-Don't switch LOCUS when making an FTP connection until logged in.
-ckcftp.c, 26 Sep 2002.
-
-Fixed LDIR to run Kermit's built-in DIRECTORY code rather than the external
-directory program. ckuusr.c, 26 Sep 2002.
-
-Protect iswild() against NULL args. ckufio.c, 26 Sep 2002.
-
-From Jeff: SET GUI WINDOW RUN-MODE { MAXIMIZE, MINIMIZE, RESTORE },
-plus variables for GUI Window X position, GUI Window Y position, GUI
-Window X resolution, GUI Window Y resolution, GUI Window Run mode.
-ckuusr.h, ckuus[24].c, 27 Sep 2002.
-
-From Ronan Flood: updated FreeBSD 1.0 makefile entry, plus an #ifdef to protect
-sysconf() calls. makefile, ckutio.c, 28 Sep 2002.
-
-Change ftp_auth() to return(0) if an AUTH command gets a 500 response, so it
-doesn't keep sending other kinds of AUTH commands. ckcftp.c, 29 Sep 2002.
-
-Changes from Jeff to yesterday's changes. ckcftp.c, 30 Sep 2002.
-
-From Jeff: SSH command-line personality. Uses same command line as the Telnet
-personality. ckcker.h, ckcmai.c, ckuus[4y].c, 3 Oct 2002.
-
-From Jeff, 7 Oct 2002:
- . SET PRINTER CHARACTER-SET. ckuxla.c, ckuusr.h, ckuus[25].c
- . Promotion of K95 to Beta.01. ckcmai.c
- . Promotion of SET GUI { MENUBAR, TOOLBAR } to visible. ckuus3.c
-
-Changed the URL parser as follows: if the username and/or password fields are
-present but empty, as in:
-
- ftp://@ftp.xyzcorp.com/somepath
- or: ftp://:@ftp.xyzcorp.com/somepath
- but not: ftp://:ftp.xyzcorp.com/somepath
-
-the pointer for these items becomes a pointer to an empty string, rather than
-a NULL pointer. Then when we go to open the connection, if the username
-string pointer points to an empty string, we prompt for the username (and/or
-password). ckuusy.c 9 Oct 2002.
-
-Jason Heskett reported an interesting bug involving a core dump when an
-ON_EXIT macro is defined that executes another macro. Sometimes. He was able
-to send a short command file that always crashed. Diagnosis: ON_EXIT, when it
-is called, pokes itself out of the macro table by setting its own entry in the
-macro name list to an empty string. But this interferes with any macro
-lookups that are done while executing ON_EXIT's body and also evidently some
-code is not happy with empty macro names... To fix: replace "on_exit" with
-"on_exxx", so the replacement keyword is (a) nonempty, and (b) doesn't wreck
-the alphabetical sorting of the table. ckuusx.c, 9 Oct 2002.
-
-Added makefile targets for FreeBSD 4.6 and 5.0. Built and tested on 4.6;
-don't know about 5.0. ckuver.h, makefile, 9 Oct 2002.
-
-Added targets for AIX 5.2 and 5.3; totally untested. ckuver.h, makefile,
-9 Oct 2002.
-
-Built current source on Unixware 7.1.3 (make uw7); it's fine. 9 Oct 2002.
-
-Promoted C-Kermit to 8.0.206 Beta.01 in hopes of a simultaneous release
-with K95 2.1. ckcmai.c, 9 Oct 2002.
-
-From Jeff: Change KERMITFONT definitions to use the new (Unicode 3.1) code
-points for the terminal graphics characters (such as VT100 horizontal scan
-lines), rather than private-use codes. ckcuni.c, 10 Oct 2002.
-
-Jason Heskett also complained that REMOTE CD would print the name of the new
-directory returned by the server even if he SET QUIET ON. This is a tricky
-one. Which server replies should the QUIET settings apply to? If I give a
-REMOTE DIRECTORY command, it means I want to see the directory listing,
-period. But if I give a REMOTE CD command, I get an "unsolicited" response
-message that SET QUIET ON should suppress. Adding message suppression to
-rcv_shortreply() is close, but not totally right; for example, it also
-suppresses the response to REMOTE PWD, which is not helpful. The only right
-way to do this is to suppress for REMOTE CD only, which can be done only by
-setting a (new) global flag, rcdactive. ckuus[r57].c, ckcpro.w, 10 Oct 2002.
-
-Ditto for REMOTE LOGIN response message ("Logged in"). ckuus7.c, 11 Oct 2002.
-
-From Jeff: SET GUI WINDOW FONT { NAME, SIZE }. ckuusr.h, ckuus4.c, 11 Oct 2002.
-
-Quick preliminary 8.0.206 build-all:
-
- OK SunOS 4.1.3
- OK Solaris 2.5.1
- OK Solaris 9
- OK AIX 4.3.3
- OK HP-UX 10.20
- OK VMS 7.1 Alpha + TCP/IP
- OK VMS 7.1 Alpha nonet
- OK VMS 5.5 VAX + TCP/IP
- OK VMS 5.5 VAX nonet
- OK Unixware 7.1.3
- OK FreeBSD 3.1
- OK FreeBSD 4.6
- OK NetBSD 1.5.2 MVME (Gerry B)
- OK Sinix 5.42
-
-Sinix build got stuck on ckuusr.c even though we're not optimizing on Sinix
-any more. Rebooting the machine fixed it.
-
-Fixed some #ifdefs for VMS in new incomplete-file deletion code in doclean().
-ckuusx.c, 11 Oct 2002.
-
-Moved uq_blah() prototypes from ckuusr.h to ckcker.h because these routines
-are called in modules that don't (and shouldn't have to) include ckuusr.h.
-11 Oct 2002.
-
-Jeff verified secure builds on Linux and Solaris.
-
-Custom-build workout: 80 different feature-selection combinations:
- . Fixed yesterday's change for NOSPL: ckcfns.c.
- . Fixed conflict between NORECALL and USE_ARROWKEYS: ckucmd.c.
- . Moved setseslog() from ckuus5.c to ckuusx.c to avoid link-time foulups.
- . Fixed an unguarded reference to zmkdir() in ckcftp.c.
- . Protected rmsg() by #ifndef NOXFER: ckuus7.c.
- . Protected initxlist() by #ifndef NOXFER: ckcmai.c.
- . Fixed unguarded references to g_url struct in xx_ftp(): ckuusy.c.
- . Fixed unguarded references to tt_snaws() in winchh(): ckutio.c.
-
---- 8.0.206 Beta.01 11 Oct 2002 ---
-
-From Jeff, 16 Oct 2002:
- . Fix K95 RMDIR: ckcfn3.c.
- . Makefile targets for Red Hat 7.2, 7.3, 8.0: ckuver.h, makefile.
- . Added \v(log_xxx) for each kind of log for PeterE: ckuusr.h, ckuus4.c.
- . Added SET TERM ATTRIBUTE DIM { ON, OFF }: ckuus[27].c.
- . Change "const" to "CONST" in some PAM declarations. ckufio.c.
-
-Added SET MATCH { DOTFILE, FIFO } { ON, OFF }. A FIFO special file is a named
-pipe, used for interprocess communication. It must be opened at both ends, so
-it's silly to match them by default; opening a FIFO and attempting to read
-will block forever unless somebody is writing into the other end. Made the
-MATCH FIFO default OFF in all cases. The dotfile default is the same as
-always (OFF for UNIX, ON elsewhere); SET MATCH DOTFILE is simply a more
-untuitive and findable command than SET WILD KERMIT /MATCH-DOT-FILES. Note
-that SET MATCH DOTFILE undoes SET OPTIONS DIRECTORY /[NO]DOTFILES, and vice
-versa. ckcmai.c, ckuusr.h, ckuus[23].c, ckufio.c. 17 Oct 2002.
-
-Added client and server end of REMOTE SET MATCH { DOTFILE, FIFO } { ON, OFF }.
-The new protocol codes are 330 and 331, respectively. ckuus[367].c, ckcfns.c,
-17 Oct 2002.
-
-Adjusted the "match dot if pattern starts with dot" heuristic in nzxpand()
-to not kick in if the filespec is "./foo". This probably needs more work.
-ckufio.c, 17 Oct 2002.
-
-Fixed typo in transcribing Jeff's ckcfn3.c code from yesterday. 18 Oct 2002.
-
-Moved some help text out of #ifdef ANYSSH that had nothing to do with SSH.
-(Idea for a new EMACS feature: M-X list-ifdef-environment.)
-ckuus2.c, 18 Oct 2002.
-
-Removed "set file { permission, protection }" keywords, which led nowhere.
-ckuus7.c, 18 Oct 2002.
-
-Added -DSV68 to all SV/68 targets. Make ckgetfqhostname() just return its
-argument in SV/68; it dumps core otherwise. In case this happens anywhere
-else, add -DNOCKGETFQHOST to CFLAGS. makefile, ckcnet.c, 18 Oct 2002.
-
-For PeterE, added SET { SEND, RECEIVE } PERMISSIONS { ON, OFF } so incoming and
-outbound permission attributes can be set separately. ckuus[27].c, 18 Oct 2002.
-
-Changed SHOW ATTRIBUTES to show In and Out permissions separately.
-ckuus5.c, 18 Oct 2002.
-
-Fixed REDO to display the command it's redoing and to add it to the bottom
-of the recall buffer. ckuusr.c, 18 Oct 2002.
-
-Discovered that DATE SATURDAY dumps core... Apparently it always did; this
-case was not included in the date-time torture test script. The crash happens
-because the DATE parsing code doesn't check for a NULL date-converion
-error-message pointer. Fixed in ckuusr.c, 18 Oct 2002.
-
-The reason DATE SATURDAY got a date-conversion error was that this path thru
-the code left a result pointer unset. Fixed in cmcvtdate(): ckucmd.c,
-19 Oct 2002.
-
-DATE SUNDAY +1DAY returned incorrect results (for any day-of-week name, any
-delta time), even though DATE TODAY +1DAY worked fine. Fixed in cmcvtdate():
-ckucmd.c, 19 Oct 2002.
-
-SET TAKE ECHO ON counted each line twice when GOTO was active. Fixed in
-dogoto(): ckuus6.c, 19 Oct 2002.
-
-Jeff noticed:
-"KERMIT READY TO GET...
- RCVD: (2 files) Last: [/amd/prost/p/kd/jaltman/.src/ckonet.c] (OK)
-the last file attempted may have been ckonet.c but it certainly was
-not the last file received" (similarly for sending). Fixed by having two
-pointers for each name; a preliminary pointer, which is set for each file at
-the beginning of the transfer (when we have all the needed info), and a final
-one that is set from the preliminary one only after the file was transferred
-successfully. This corrects not only the automatic "wheremessage" at the end
-of a remote-mode transfer, but also the WHERE and SHOW FILE command results.
-ckuusx.c, ckcfn[s3].c, ckcpro.w, 19 Oct 2002.
-
-From Jeff: Improve ORIENTATION message for K95 to say which directories are
-for which INI files. ckuusr.c, 23 Oct 2002.
-
-Removed Beta designation from herald. ckcmai.c, 23 Oct 2002.
-
-Put final dates and ID strings in Unix and VMS build procedures.
-Makefile, ckvker.com, 23 Oct 2002.
-
-Build-all... #ifdef adjustments: ckcfns.c... 83 different feature-set
-combinations build OK on Linux. 23 Oct 2002.
-
-From Jeff: SET WIN95 HORIZONTAL-SCAN-LINE-SUBSTITUTIONS. ckuusr.h, ckuus7.c,
-24 Oct 2002.
-
-Fixed Heath-19 graphic character-set table to use new Unicode 3.1 values
-if WIN95 HORIZ OFF. ckcuni.c, 24 Oct 2002.
-
-Changed tx_usub() to return Unicode 3.1 values if WIN95 HORIZ OFF.
-ckcuni.c, 24 Oct 2002. <-- No backed off on this.
-
-Some problems during build-all:
-
- . VMS 7.1 TGV 4.2: If I make a Telnet connection with it, then try to send
- a file (itself. wermit.exe) over the connection, the connection drops
- after about 20%, the thermometer zooms out to 100% and SUCCESS is reported.
- This doesn't happen with UCX.
-
- . VMS 7.3 TGV 4.3: ckcmai.c won't compile because of a complaint about the
- declaration of select() (which ckcmai.c doesn't use) in
- SYS$COMMON:[SYSLIB]DECC$RTLDEF.TLB. Ditto in VMS 7.2 TGV 4.3.
- Adding NOSELECT to CFLAGS doesn't help. I don't think the VMS version
- even uses select(). But the TGV 4.3 builds were OK in 8.0.201, so what
- changed? I don't see anything in ckcnet.h that would have done it.
-
-It builds OK with VMS 7.1 / TGV 4.2 but sending files on Telnet connections
-fails in a strange way: the connection drops, but the thermomoter goes to 100%
-and success is reported. I don't know why the connection is dropping (s_errno
-is 32 == "broken pipe"), but the spurious success indication is because of
-a double failure in sdata(): (1) The packet-sending loop index could go
-negative without breaking the loop when streaming; (2) if spack() fails,
-sdata() should return -2, not -1 (which means EOF). Also if any ttchk() in
-sdata() returns < 0, sdata should return -2. I fixed this code (which has
-been this way for YEARS) and now VMS C-Kermit properly fails when it gets
-the spack() error, but ttchk() in this case still doesn't think the connection
-is lost, but that must be our new problem with MultiNet. ckcfns.c,
-27 Oct 2002.
-
-The compilation failure in ckcmai.c is a clue... The problem was that I added
-#ifdef VMS / #include <time.h> / #endif to shut up complaints about the time()
-call. Evidently something in VMS <time.h> gives MultiNet a bad case of
-indigestion; removing it fixes the compilation and the result works fine. The
-transmission failures in the other case seem to be a coincidence -- something
-to do with the U of Arizona (probably some obscure VMS quota on my IDs there,
-or some kind of network connection throttling), since it doesn't happen
-anywhere else. ckcmai.c, 27 Oct 2002.
-
-Changed four occurrences of "void" to "VOID" in ckcftp.c, 27 Oct 2002.
-
-Defined NOCKFQHOSTNAME for HPUXPRE65. Might also need this for HP-UX 7
-and maybe 8. ckcnet.c, 27 Oct 2002.
-
-From Jeff: PAM_CONST definition to clear up warnings caused by different
-vendors' definitions of PAM structs. ckufio.c, 28 Oct 2002.
-
-Unixware 2.1.0 build bombs immediately with "UX:make: ERROR: line too long"
-(which line?) Not worth chopping up the makefile to fix but in a pinch it
-could be done. 2.1.3 builds OK.
-
-Did another 20-some platform builds, bringing the total to 83, plus a final
-runthrough of the build-with-84-different-feature-set-combinations script on
-Linux. Should be good to go!
-
---- 8.0.206 24 Oct 2002 ---
-
-Finally got access to Linux on IA64 again. Builds OK but dumps core
-immediately on startup. Adding -DNOCKGETFQHOST was necessary but not
-sufficient. In this case, the very call to ckgetfqhostname() from ckhost()
-(which is in ckuusx.c) was dumping core; thus I had to move the definition of
-NOCKGETFQHOST from ckcnet.c to ckcdeb.h, add an #ifdef __ia64__ clause to it,
-and protect the call to ckgetfqhostname() with it. Obviously there has to be
-a better fix but this will have to for now. ckcnet.c, ckuusx.c, ckcdeb.h,
-31 Oct 2002.
-
-Link step fails in Mandrake 9.0 with undefined references to res_search,
-dn_expand, and crypt. Turns out the linux makefile target tests for the
-existence of libcrypt.a and libresolv.a, but in Mandrake 9.0 they exist
-only as *.so. Changed linux target to look for both. makefile, 1 Nov 2002.
-
-Vace reported that "ftp mget a b c" would get ALL files from the server's
-directory if c did not exist. Diagnosis: off-by-one error in counting MGET
-args processed. Naturally fixing this bug revealed another (this time
-cosmetic) one, which resulted in spurious error messages when hitting MGET
-args that have no match on the server. Fixed in ckcftp.c, 1 Nov 2002.
-
-Rebuilt about 60 of the most important Unix binaries to pick up the fixes
-31 Oct - 1 Nov 2002, and refreshed the FTP site with new sources, tarballs,
-ZIP files, etc. Sat Nov 2 19:11:30 2002
-
-From Martin Vorlaender and Jeff, SSL/TLS support for VMS:
-ckuusr.h, ckuath.h, ckcnet.c, ckctel.c, ckuath.c, 10 Nov 2002.
-
-Added PASV as invisible synonym for PASSIVE. ckcftp.c, 10 Nov 2002.
-
---- 8.0.206 24 Oct 2002 #2 ---
-
-More work on SSL in VMS: Jeff + Martin Vorlaender: ck_ssl.c ckcmai.c ckcnet.c
-ckctel.c ckuath.h ckvcon.c ckvtio.c ckvker.com 10-15 Nov 2002.
-
-Discovered that ckvfio.c would not compile on VMS 6.1 with UCX 4.1 because
-<conv$routines.h> was missing, which is explicitly included. Enclosed the
-#include in #ifdef NOCONVROUTINES..#endif and rebuilt with
-@[users.fdc.src]ckvker.com "" "" "NOCONVROUTINES". 16 Nov 2002.
-
-Fixed the "ftp mget */data/*" problem with two small changes to doftpget():
-ckcftp.c, 16 Nov 2002. Placed a copy of ckcftp.patch in ~kermit/f.
-
-From Lucas Hart: Fixes for VAX C 2.x and CMU TCP/IP. "Can't guarantee that
-the revised CKVOLD will work for all combinations of more recent
-VMS/compiler/TCPIP releases, but I've tested it for compatibility on our AXP
-VMS 6.2, UCX 4.0, DECC 5.6, your AXP VMS 7.1, DEC TCPIP 5.1, DECC 6.0 as well
-as with VAX VMS 5.4, VAX C 3.2, CMU12 and VAX VMS 4.7, VAX C 2.4." ckvfio.c,
-ckvtio.c, ckuus5.c, ckvker.com, ckvold.com, 17 Nov 2002.
-
-From Jeff: More work on VMS SSL. Now it actually works, even in CONNECT mode,
-except it hangs when it gets an error alert or the remote closes the
-connection. ckcnet.c. ckvtio.c, 17 Nov 2002.
-
-NOTE: Lucas's changes should go into the 8.0.206 source code but it's too
-late since ckvtio.c (upon which he based his changes) is already full of
-SSL code.
-
-MGET in K95 in totally broken FOR SOME PEOPLE (mainly me) if the TMP (or TEMP)
-value is too long. It works fine if you set these to C:\TMP. Diagnosis: (1)
-we were malloc'ing only 16 bytes for the temp file name (I think this was my
-fault -- I was only looking at the "ckXXXXXX" part and forgetting that this
-was appended to the TMP path); (2) the Windows version of mktemp() wants you
-to use the value pointed to by the pointer it returns, rather than assuming
-the mktemp() arg will be modified in place. The code was changed to malloc a
-longer string and to use the return value from mktemp() (if any) rather than
-assuming that mktemp() modified its argument string (in K95 only -- not sure
-about Unix platforms; the man pages differ on this, but at least this way if
-some mktemp() version does NOT alter its argument, we still have a usable
-filename (like /tmp/ckXXXXXX)). Of course this won't be good for recursive
-MLSD downloads, but we can always issue patches for the Unix version later if
-needed. The Linux and BSD versions use mkstemp() anyway. There is, however,
-a danger of a memory leak in the Unix version if the user has defined a TMPDIR
-or CK_TMP environment variable whose value is longer than 9 bytes. All this
-is highly unlikely so we should be OK. ckcftp.c, 17 Nov 2002.

---- K95 2.1.1 and updated ck[uv]206.{tar,zip} but not C-Kermit binaries ---

---- K95 2.1.2 and C-Kermit 8.0 CDROM ---
-
-From Jeff, 28 Nov 2002:
- . Updated SSL modules: ck_ssl.[ch].
- . Fixed cipher-list display in SHOW AUTH & FTP ssl_auth(): ckuus7.c. ckcftp.c
- . Some minor tn_wait() fixes: ckctel.c.
- . Preliminary SSL support for VMS CONNECT: ckvcon.c.
-
-Bumped C-Kermit edit number to 207.
-
-From Jeff, 29 Nov 2002: "[C-Kermit was dumping core on SCO OSR5 Telnet Com Port
-connections because] the SCO compiler treats all characters as signed. This
-was causing 'sprintf(buf,"02x ",ch);' to produce strings such as "ffffffc2"
-instead of "c2" for values between 128 and 255. This wrote beyond the end of
-a buffer and blew away the stack. Having fixed this I also noticed that
-conect() did not properly check for carrier when TN CPC was negotiated. This
-has now been fixed as well." ckucns.c, ckucon.c, ckctel.c, 29 Nov 2002.
-
-From Jeff, 30 Nov 2002: Fix SSL for VMS and also carry forward the CPC fixes
-to VMS. ckcnet.c, ckvtio.c, ckvcon.c, 30 Nov 2002.
-
-Changed copyright dates that are displayed (but not yet all the internal
-ones) from 2002 to 2003. ckcmai.c, 3 Jan 2003.
-
-Fixed the FTP module's brief-format transaction log, which had the status
-inverted: OK for FAILED and v.v. ckcftp.c 3 Jan 2003.
-
-From Jeff, 4 Jan 2003:
- . Make /MOVE-TO:xxx convert xxx to full pathname: ckuus[r67].c,
- . Make SHOW OPTIONS ALL show both kinds of options: ckuus2.c.
- . More command-line personalities: ckcmai.c, ckuusy.c.
- . New NOSCROLL command for K95: ckuusr.[ch], ckuus2.c.
- . New lockdown and other command-line options: ckuusr.h, ckuusy.c.
- . SSL interface updated to OpenSSL 0.9.7: ck_ssl.c.
- . SET TERM LINE-SPACING and CURSOR xxx NOBLINK: ckuus[27]c.
- . Expanded SHOW GUI command: ckuus3.c
- . New SHOW TABS code: ckuus5.c.
-
-Updated SUPPORT (BUG), NEWS, and INTRO texts. ckuus[26].c. 5 Jan 2003.
-
-Fixed FTP module to suppress "'FEAT': Command not understood" message
-unless FTP DEBUG is ON. ckcftp.c, 6 Jan 2003.
-
-Got a report that C-Kermit dumps core on Solaris when executing a certain
-script. Seems to be related to changing vnambuf[] in zzstring() from an
-automatic array to a malloc'd buffer (see notes from 29 Jun 2000). Changed
-it to an automatic buffer except for K95. ckuus4.c, 6 Jan 2003.
-
-Nope, that's not it. It evidently happens only after FTP PUT has been used.
-Fixed solaris9g makefile target to include -funsigned-char and built a new
-binary. Determined that building with gcc and -funsigned-char makes no
-difference. makefile, 7 Jan 2003.
-
-I did a preliminary audit, looking at the items in the left column: if used in
-a given routine, are there any obvious mistakes:
-
- 1 2 3 4 5
- doftpput->putfile->sendrequest->doftpsend2->secure_write
-malloc OK OK OK OK OK
-makestr OK OK OK OK OK
-automatic arrays OK OK OK OK OK
-[ck]str[n]cpy OK OK OK OK OK
-[ck]str[n]cat OK OK OK OK OK
-sprintf OK OK OK OK OK
-nzltor OK OK OK OK OK
-zfnqfp OK OK OK OK OK
-memcpy OK OK OK OK OK
-bcopy OK OK OK OK OK
-
-secure_write sends the data directly on clear-text connections. On secure
-connections, it calls secure_putbuf(), which calls secure_putbyte(), but we
-aren't using those, so secure_write() is the end of the call chain for FTP
-PUT. doftpsend2 has buf[] as an automatic array, which it reads file data
-into using zxin (binary mode only), but this looks OK. Still, I changed it
-read 1 less than the buffer size (fread) just in case. Also there was one
-debug() statement that referred to an automatic array (fullname[]) before it
-was initialized (but not used in this case), which I fixed. ckcftp.c,
-7 Jan 2003.
-
-FTP GET /RECURSIVE somepath/somefile still didn't work, despite what the
-notes of 19 Sep 2001 say. There are so many paths through the code,
-depending on switch values, GET vs MGET, etc, that a crucial spot was missed.
-Fixed in doftpget(): ckcftp.c, 7 Jan 2003.
-
-Back to the core dump... after two days of full-time debugging, I found the
-culprit: the buffer-full test in the zzout() macro should have been ">="
-rather than just ">", thus Kermit wrote 1 byte past the end of the malloc'd
-FTP PUT output buffer, ucbuf. Why did it never happen in K95? Because, since
-it's a secure build, FUDGE_FACTOR is defined there. But it's not defined in
-Solaris or other clear-text builds. Although the crash wouldn't happen in
-secure builds, the 1-byte leak might have caused errors in the data transfer.
-In non-Solaris clear-text builds, like Linux, I suspect that malloc() tends
-add something for safety (especially given the man page statement that it
-allocates "at least" what you asked for). Another reason the problem escaped
-notice is that zzout() is used only for text-mode PUTs (and then only when
-there is no character-set translation), but most transfers these days are
-binary and/or downloads. Anyway, in the course of debugging, a lot of small
-cleanups were done: sizeof(blah) for all arrays was replaced by the same
-symbolic size that was used to allocate the array, numeric array sizes were
-replaced with symbolic ones, etc. The real fix is one character long.
-ckcftp.c, 9 Jan 2003.
-
-Got a report that "mget /recursive */somedir/*" downloaded the files into
-the current directory, rather than re-creating the remote directory structure.
-Fixed in doftpget(): ckcftp.c, 10 Jan 2003.
-
-Unix C-Kermit did not allow file transfer if started under inetd and accessed
-via Internet raw socket (or whatever). Diagnosis: isatty() and friends would
-fail causing ttopen() to fail. Fixed by adding escape clauses for "-l 0"
-situations (i.e. Kermit invoked with an already-open file descriptor) at the
-appropriate places. ckcmai.c, ckutio.c, 14 Jan 2003.
-
-From Jeff for K95 2.1.3
- . Add test for startflags & 128 to trap() for ignoring BREAK.
- . Fix for SHOW TRANSMIT.
-
---- K95 2.1.3 ---
-
-FTP USER, FTP ACCOUNT, plus the various prompts and switches for FTP username,
-password, and account all neglected to strip quotes, and in most cases quotes
-are necessary to specify a username that contains spaces. ckcftp.c,
-15 Jan 2003.
-
-FTP MPUT f1 f2 f3... gets a parse error if any of the fn's do not match an
-existing file. This is bad for scripts. In doftpput(), cmfdb() looks for
-keywords (switches) or CMIFI. When it hits CMIFI, it exits from the initial
-parse loop and then does additional cmifi()s in a loop until done. The most
-obvious fix is to parse each field with cmfdb(CMIFI,CMFLD), i.e. fall back to
-CMFLD if CMIFI doesn't match anything. Then if CMFLD was used, we don't add
-the filespec to the list. This is a rather big change but it seems to work.
-No error messages or failures happen for non-matching fields, but an error
-message is printed (and the MPUT command fails) if none of the fields match
-any files. This fix got in too late for 2.1.3; workaround: use C-Shell
-like wildcard list (ftp mput "{*.abc,foo.*}"). ckcftp.c, 16 Jan 2003.
-
-GREP did not pass its pattern through the expander, thus variables could
-not be used for patterns. This must have been an oversight -- I can't find
-anything in my notes about it. Fixed in dogrep(): ckuus6.c, 24 Jan 2003.
-
-New makefile target for HP-UX 11.xx with OpenSSL from Tapani Tarvainen.
-makefile, 31 Jan 2003.
-
-From Jeff:
- . Avoid core dump when dereferencing tnc_get_signature(): ckuus4.c.
- . Bump version numbers to 8.0.208, 2.1.4: ckcmai.c.
-
-Added /NOLOGIN to FTP [OPEN]. ckcftp.c, 10 Feb 2003.
-
-Don't dump core if FTP DEBUG is ON and FTP OPEN does not include a service.
-openftp(): ckcftp.c, 10 Feb 2003.
-
-HELP PATTERN text incorrectly identified commands and functions with
-floating and anchored patterns. The corrected lists are:
-Floating: GREP, TYPE /MATCH:, /EXCEPT: patterns, \farraylook(),
-Anchored: IF MATCH, file-matching wildcards, \fsearch(), \frsearch()
-ckuus2.c, 10 Feb 2003.
-
-INPUT n \fpattern(xxx) did not work for case-independent comparisons.
-Fixed in doinput(): ckuus4.c, 10 Feb 2003.
-
-It seems \fpattern() didn't work with MINPUT at all. There was no code to
-handle \fpattern() in the MINPUT parse loop, so it never worked. The code
-had to be totally rewritten to use cmfld() in a loop, rather than cmtxt()
-and then cksplit(). Furthermore, whenever any of the fields was an
-\fjoin(), this had to be split. ckuusr.c, 10 Feb 2003.
-
-Macro replacement via \m() and \fdefinition() does not work as advertised
-(i.e. case sensitively) for associative array elements; e.g. \m(xxx<abc>) is
-treated the same as \m(xxx<ABC>), contrary to section 7.10.10 of the C-Kermit
-7.0 update notes, and to the fact that the two really do exist separately.
-Fixed by adding a static function isaarray(s) which succeeds if s is an
-associative array reference and fails otherwise, and then having \m()
-and \fdef() call mxxlook() (case-sensitive lookup) if isaarray(), otherwise
-(as before) mxlook()). ckuus4.c, 11 Feb 2003.
-
-Fixed FTP OPEN to allow the /USER switch to override SET FTP AUTOLOGIN OFF,
-just as /NOLOGIN overrides SET FTP AUTOLOGIN ON. ckcftp.c, 11 Feb 2003.
-
-In K95, "set key \1234 \27H" (any SET KEY command in which the first char of
-the definition was backslash, and the ONLY character after the backslash
-quantity was an uppercase letter, that letter would be lowercased). Diagnosis:
-xlookup() poking its argument (see notes from July 2000). Jeff sent a fix.
-ckucmd.c, 15 Feb 2003.
-
-Ran my S-Expression torture test to make sure Sexps still worked. They do,
-except the bitwise & and | operators were broken, e.g. (& 7 2) and (| 1 2 4)
-get "Invalid operand" errors. Jeff's code had added an early failure return
-from the lookup loop when when a single-byte keyword matched a keyword that
-started with the same byte but was more than one byte long. So "&" would hit
-"&&" and fail instead of continuing its search (xlookup tables aren't sorted
-so there can be no early return). Fixed in xlookup(): ckucmd.c, 16 Feb 2003.
-
-Got rid of "krbmit" target from makefile. It's still there, but we don't
-use it any more. All secure targets now use "xermit", and produce a binary
-called wermit, just like the regular ones do (except the old ckucon.c ones).
-Non-secure targets, since they don't define any of the security symbols,
-wind up compiling and linking to (mostly) empty security modules. makefile,
-15 Feb 2003.
-
-Added \fcvtdate(xxx,3) to format its result in MDTM format (yyyymmddhhmmss,
-all numeric, no spaces or punctuation). Of course these numeric strings
-are too big to be 32-bit numbers and are useless for arithmetic, but they're
-useful for lexical comparison, etc. ckuus[24].c, 16 Feb 2003.
-
-The following FTP commands did not set FAILURE when they failed: RMDIR,
-CD, CDUP, Fixed in the corresponding doftpblah() routines. ckcftp.c,
-16 Feb 2003.
-
-RENAME would sometimes not print an error message when it failed, e.g. in K95
-when the destination file already existed. ckuus6.c, 17 Feb 2003.
-
-Fixed COPY error messages, which did not come out in standard format when
-/LIST was not included. ckuus6.c, 17 Feb 2003.
-
-Fixed #ifdefs in ck_crp.c to allow nonsecure builds on old platforms like
-System V/68 R3. 19 Feb 2003.
-
-Similar treatment for ck_ssl.c. 20 Feb 2003.
-
-From Jeff, 21 Feb 2003:
- . AIX53 and AIX52 symbols for ckcdeb.h, makefile.
- . New gcc targets for various AIX 4.x/5.x versions: makefile.
- . Copyright date updates: ck_crp.c, ck_ssl.c.
- . ENABLE/DISABLE QUERY broken because keyword table out of order: ckuusr.c.
- . Fixed the use of HTTP proxies for HTTP [RE]OPEN for Unix: ckcnet.c.
-
-Also for K95 only: Allow file transfer when K95 is invoked on the remote end
-of a connection to a Pragma Systems Terminal Server connection; automatically
-SET EXIT HANGUP OFF when invoked with open port handle ("k95 -l nnnn").
-
-"cd a*" failed even when "a*" matched only one directory. Fixed in cmifi():
-ckucmd.c, 21 Feb 2003.
-
-In the Unix version, replace "extern int errno;" with "#include <errno.h>"
-if __GLIBC__ is defined, since glibc now defines a thread-specific errno.
-ckcdeb.h, 26 Feb 2003.
-
-Added #ifdefs to skip compilation of ckuath.c in nonsecure builds. Tested
-by building both secure and regular versions in Linux. ckuath.c, 26 Feb 2003.
-
-Ran the build-in-84-different-configurations script on Linux to make sure it
-still builds with all different combinations of feature selection options.
-All OK. 26 Feb 2003.
-
-Built on VMS. Needed to add a prototype for mxxlook*() to ckuusr.h; built
-OK otherwise. 26 Feb 2003.
-
-From Jeff: More #ifdef shuffling for nonsecure builds: ckuath.c, ck_ssl.c,
-27 Feb 2003.
-
-Added code to ensure \v(download) ends in a directory separator in Unix,
-Windows, and OS/2. ckuus7.c, 27 Feb 2003.
-
-Added code to K95 zfnqfp() to tack on directory separator when returning
-a directory name. ckofio.c, 27 Feb 2003.
-
-Somehow an old copy of ckuath.c popped to replace the new one. Put the new
-one back. 28 Feb 2003.
-
-From Jeff: Fix typo in my K95 zfnqfp() code from yesterday; fixes for handling
-UNCs uniformly, no matter which way their slashes are leaning. ckofio.c,
-28 Feb 2003.
-
-At Jeff Mezei's suggestion, separate text and binary mode open sequences
-for VMS session log. ckvfio.c, 28 Feb 2003.
-
-Added freebsd48 target for FreeBSD 4.8. makefile, 1 Mar 2003.
-
-Changed Mac OS X entries to include -DUSE_STRERROR. makefile, 2 Mar 2003.
-
-Fixed GETOK /GUI to evaluate its text argument. ckuus6.c, 3 Mar 2003.
-
-Jeff fixed the K95 Dialer QUICK dialog to (a) allow templates, and (b) have
-a Save-As option. 3 Mar 2003.
-
-Jeff fixed a problem with the Xmodem-CRC checksum being crunched whenever
-there was a retransmission. 7 Mar 2003.
-
-Added target/banner for Tru64 5.1B. makefile, ckuver.h, 5 Mar 2003.
-
-In Unix, the zcopy() routine (used by the COPY command) reset the user's umask
-to 0 for the remainder of the Kermit process lifetime. The bug was in
-ckufio.c 8.0.194, 24 Oct 2002, and is fixed in ckufio.c 8.0.195, 6 Mar 2003.
-Of course this happened after building 155 C-Kermit 8.0.208 binaries. (But
-before officially releasing 8.0.208.)
-
-In the VMS version, changed:
-
- while ((n--) && xx_inc(2) > -1) ;
-to:
- while ((n--) && xx_inc(2) >= 0) ;
-
-to suppress the "...is being compared with a relational operator to a constant
-whose value is not greater than zero" warning. ckvtio.c, 7 Mar 2002.
-
-Added a debug call to dologend in hopes of catching overzealous Locus
-switching, which seems to happen only in K95. ckuus3.c, 7 Mar 2002.
-
-Rebuilt binaries for some of the more current Unix releases: AIX 4.3.3-5.1,
-Solaris 7-9 , Red Hat 7.0-8.0, Slackware 8.1, Freebsd 4.7-4.8, NetBSD 1.6,
-OpenBSD 3.2, Unixware 7.1.3, Open Unix 8, OSR5.0.6a, etc. A Unix binary with
-COPY umask fix shows a 6 Mar 2003 date for "UNIX File support" in SHOW
-VERSIONS; a binary without the fix shows 24 Oct 2002.
-
-C-Kermit 8.0.208 dated 14 March 2003 released on 10 March 2003.
-
----8.0.208---
-
-From Jeff 13 Mar 2003:
- . Updated SSL module allows importation of tickets from host.
- . freebsd50+openssl target: makefile.
- . FTP PUT /PERMISSIONS error message for K95: ckcftp.c.
-
-Fixed MINPUT to strip quotes or braces from around targets (this was broken
-on Feb 10th). Thanks to Jason Heskett for discovering and reporting this
-(killer) bug. ckuusr.c, 14 Mar 2003.
-
-Changed version number to 209 Dev.00. ckcmai.c, 14 Mar 2003.
-
-While debugging the alphapage script, I found that the command "minput 8 \6\13
-\21\13 \13\27\4\13 \30\13" gets "?Not confirmed" in 8.0.208 and 8.0.209, but
-not in 206 and earlier. This problem too was introduced on Feb 10th by
-changing MINPUT parsing from cmtxt() followed by cksplit() to cmfld() in a
-loop. cmfld() uses setatm() to return its result and of course setatm()
-breaks on \13. Changing setatm() not to do this would break everything else.
-But cmfld() has no arguments that let us tell it to do anything different in
-this case. Changing the API would be a disaster. The only solution is to add
-an "MINPUT ACTIVE" (minputactive) global variable that tells cmfld() to tell
-setatm() not to break on CR. Now MINPUT with braced targets containing CR
-and/or LF works in 209, 206, and 201 (but not 208). ckucmd.c, ckuusr.c,
-ckuus5.c, 15 Mar 2003.
-
-MINPUT n \fjoin(&a) works OK if all the members of \&a[] are text strings, but
-if they are strings of control chars (as above), they don't get separated by
-the spaces. For example in:
-
- dcl \&a[] = "\4\5" "\6\7" xxx
- minput 10 \fjoin(&a)
-
-MINPUT gets two targets: "aaa" and "\4\5 \6\7 xxx". The bug was in the
-cksplit() call in the \fjoin() case of MINPUT: it needed to specify an
-include set consisting of all the control characters except NUL. ckuusr.c,
-16 Mar 2003.
-
-But there's still a problem:
-
- dcl \&a[] = "\4\5\13\10" "\6\7" "xxx"
-
-creates an array whose first member is "^D^E (one doublequote included). But
-if braces are used instead, there's no problem. Same deal as MINPUT: cmfld()
-breaks on CR or LF, thus the end quote is lost. If I set minputactive for
-DECLARE initializers too, that fixes it. Is there any reason not to do this?
-Can't think of any (famous last words)... ckuusr.c, 16 Mar 2003.
-
-Since it has multiple applications, changed the flag's name from minputactive
-to keepallchars. ckucmd.c, ckuus[r5].c, 16 Mar 2003.
-
-\v(exedir) wasn't being set correctly (it included the program name as well
-as the directory). Fixed in getexedir(): ckuus4.c, 16 Mar 2003.
-
-SET CARRIER-WATCH <Esc> "auto matic" (spurious space in supplied keyword).
-Cosmetic only; it still worked. Fixed in setdcd(): ckuus3.c, 16 Mar 2003.
-
-"directory a b c" listed too many files -- all files whose names END WITH a,
-b, or c, rather than the files whose names WERE a, b, or c. Diagnosis: The
-filespec is changed into a pattern: {a,b,c}, which is the correct form. It is
-passed to nzxpand(), which goes through the directory getting filenames and
-sending each one to ckmatch() with the given pattern. ckmatch() receives the
-correct pattern but then prepends a "*" -- that's not right. It's not just
-in filename matching either. The following succeeds when it shouldn't:
-
- if match xxxxc {{a,b,c}} <command>
-
-Changing ckmatch() to not prepend the "*" to each segment fixes the command
-above but breaks lots of others. Running through the "match" torture-test
-script shows the problem occurs only when the {a,b,c} list is the entire
-pattern, and not embedded within a larger pattern. Testing for this case
-fixed the problem. ckmatch(): ckclib.c, 16 Mar 2003.
-
-Fixed FTP MODTIME to not print anything if QUIET ON. ckcftp.c, 16 Mar 2003.
-
-Picked up a new ckuath.c from Jeff, not sure what the changes are. 16 Mar 2003.
-
-Did a few regular and secure builds to make sure I didn't wreck anything.
-
-Changed version number to 209 (final). ckcmai.c, 16 Mar 2003.
-
-Jason Heskett found another bug: if you define a macro FOO inside the
-definition of another macro BAR, and FOO's definition includes an odd number
-of doublequotes (such as 1), FOO's definition absorbs the rest of BAR's
-definition. Example:
-
- def TEST {
- .foo = {X"}
- sho mac foo
- }
- do test
- sho mac foo
-
-Results in:
-
- foo = {X"}, sho mac foo
-
-Diagnosis: the TEST definition becomes:
-
- def TEST .foo = {X"}, sho mac foo
-
-and the macro reader is erroneously treating the doublequote as an open
-quote, and then automatically closes the quote at the end of the definition.
-The error is that a doublequote should be significant only at the beginning of
-a field. But the macro reader isn't a command parser; it doesn't know what
-a field is -- it's just looking for commas and skipping over quoted ones.
-First we have to fix an oversight: SET COMMAND DOUBLEQUOTING OFF should have
-worked here, but it wasn't tested in this case. Fixed in getncm(): ckuus5.c,
-17 Mar 2003.
-
-There are only certain cases where it makes sense to treat doublequotes as
-signicant:
-
- . An open quote must be at the beginning or preceded by a space.
- . A close quote is only at the end or else followed by a space.
-
-This too was fixed in getncm(): ckuus5.c, 17 Mar 2003.
-
-A fix from Jeff SSL/TLS FTP data decoding. ckcftp.c, 18 Mar 2003.
-
-Tried building C-Kermit on a Cray Y-MP with UNICOS 9.0. "int suspend",
-declared in ckcmai.c and used in many modules, conflicts with:
-
- unistd.h:extern int suspend __((int _Category, int _Id));
-
-The "=Dsuspend=xsuspend" trick doesn't work for this; there is no way around
-the conflict other than to rename the variable: ckcmai.c, ckutio.c,
-ckuus[35xy].c. 26 Mar 2003. VMS and K95 not affected.
-
-OK that gets us past ckcmai.c... Then in ckutio.c I had to add a new #ifdef
-around the LFDEVNO setting, because the Cray didn't have mkdev.h. Could not
-find a Cray-specific manifest symbol, so I made a new makefile target (cray9)
-that sets this symbol. Having done this I have no idea what kind of lockfile
-would be created, but I also doubt if anybody dials out from a Cray. The
-binary should run a C90, J90, or Y-MP. makefile, 26 Mar 2003.
-
-Added a target for SCO OSR5.0.7. makefile, ckuver.h, 30 Mar 2003.
-
-Changed since 208:
-makefile ckuver.h ckcmai.c ckclib.c ckcftp.c ckucmd.c ckuus*.c ckutio.c.
-
----8.0.209---
-
-From Mark Sapiro, a fix for the March 17th doubleqote fix, getncm(): ckuus5.c,
-4 Apr 2003.
-
-From Jeff, 29 Apr 2003:
- . Corrected target for HP-UX 11.00 + OpenSSL: makefile,
- . Do not allow WILL AUTH before WONT START_TLS: ckctel.h ckctel.c
- . Add hooks for SFTP and SET/SHOW SFTP: ckcdeb.h ckuusr.h ckuusr.c ckuus3.c
- . Add SKERMIT ckuusr.h ckuusr.c
- . Add ADM-5 terminal emulation: ckuus7.c, ckuus5.c
- . Uncomment and update HELP SET SSH V2 AUTO-REKEY: ckuus2.c
- . Enable IF TERMINAL-MACRO and IF STARTED-FROM-DIALER for C-Kermit: ckuus6.c
- . Fix conflicting NOSCROLL keyword definition: ckuusr.h
- . Set ttname when I_AM_SSH: ckuusy.c
- . Add extended arg parsing for SSH, Rlogin, Telnet: ckuusy.c, ckuus4.c
- . Security updates: ckuath.c, ck_ssl.c
- . Change K95 version number to 2.2.0: ckcmai.c
- . Save K95 term i/o state before executing keyboard macro: ckuus4.c
- . Add tests for SSH Subsystem active during INPUT/OUTPUT/CONNECT: ckuus[45].c
- . Enable K95 SET SSH V2 AUTO-REKEY: ckuus3.c
-
-SFTP and SET SFTP subcommands are implemented up to the case statements.
-
-Files of mine that Jeff hadn't picked up:
- ckuver.h ckcftp.c ckutio.c ckuusx.c (just minor changes for last build-all)
-
-On 4 Jan 2003, SET RECEIVE MOVE-TO was changed to convert is argument to an
-absolute path, which made it impossible to specify a relative path, then
-move to different directories and have it apply relatively to each directory.
-Changed this as follows:
-
- . Parser uses cmtxt() rather than cmdir() so it won't fail at parse time.
- . If path is absolute, we fail at parse time if directory doesn't exist.
- . In reof() we run the the path through xxstring (again, in case deferred
- evaluation of variables is desired) and then, if not null, use it.
- . If the directory doesn't exist, rename() fails and reof() returns -4,
- resulting in a protocol error (this is not a change). We do NOT create
- the directory on the fly.
-
-I also fixed SET SEND/RECEIVE RENAME-TO to parse with cmtxt() rather than
-cmdir(), since it's parsing a text template, not a directory name, e.g.
-"set receive rename-to file-\v(time)-v(date)-\v(pid)". This was totally
-broken, since when I don't know. We don't call xxstring() in this parse, so
-evaluation is always deferred -- I'd better not change this. ckuus7.c,
-ckcfns.c, 1 May 2003.
-
-From Jeff, Sat May 3 14:15:23 2003:
- . Pick up the right isascii definition for K95: ckctel.c
- . malloc... ckuath.c (new safe malloc routines for K95)
- . Add author listing: ckuus5.c
- . SSH Heartbeat support (K95 only): ckuus[23].c
- . Prescan --height and --width to avoid window resizing at startup: ckuusy.c
- . Add checks for fatal() or doexit() called from sysinit(): ckuusx.c
- . Move some K95-specific definitions to ckoker.h: ckcdeb.h
- . Add support for ON_CD macro in zchdir(): ckufio.c
- . Add a command to let FTP client authenticate with SSLv2: ckcftp.c
- . Fix parsing of FTP file facts like "UNIX.mode": ckcftp.c
-
-ON_CD will need some explaining (to be done). It's implemented for Unix,
-VMS, WIndows, and OS/2.
-
-The FTP file facts fix came from first exposure to the new OpenBSD FTP
-server: ftp://ftp7.usa.openbsd.org/pub/os/OpenBSD/3.3/i386/
-The period in "UNIX.mode" caused an erroneous word break, adding junk to
-the filename.
-
-About the malloc changes, Jeff says "K95 is not behaving well in low memory
-environments. I'm not sure that C-Kermit does much better. The program does
-not crash but it certainly does not behave the way the user expects it to.
-I'm beginning to think that any malloc() error should be treated as fatal."
-
-Not visible in these changes because it's in K95-specific modules: Jeff made
-SET ATTRIBUTES OFF and SET ATTRIBUTES DATE OFF apply to XYZMODEM transfers.
-
-From Jeff, 11 May 2003:
- . Add support for SSH Keepalive to relevant SET command (K95): ckuus3.c
- . Reduce max overlapped i/o requests from 30 to 7 (K95): ckuus7.c
- . Don't call sysinit() in fatal(): ckuusx.c.
- . Some new conditionalizations for SSL module: ck_ssl.c
-
-The doublequote-parsing fixes from March and April broke the SWITCH statement,
-which is implemented by internally defining, then executing, a macro. If I
-drop back to the old dumb handling of doublequotes, everything is fixed except
-the problem of March 17th. But can we really expect getncm() to pre-guess
-what the parser is going to do? getncm()'s only job is to find command
-boundaries, which are represented by commas. Commas, however, is needed IN
-commands too. We take a comma literally if it is quoted with \, or is inside
-a matched pair of braces, parens, or doublequotes. It is not unreasonable to
-require a doublequote in a macro definition to be prefixed by \ when it is to
-be taken literally. The proper response to Jason Heskett's complaint of March
-17th should have been to leave the code alone and recommand an appropriate
-form of quoting:
-
- def TEST {
- .foo = {X\"}
- sho mac foo
- }
-
-And this is what I have done. Another reason for sticking with the old method
-is that it's explainable. The "improved" method, even if it worked, would be
-be impossible to explain. Btw, in testing this I noticed that the switch-test
-script made 8.0.201 dump core. Today's version is fine. The problem with
-quoted strings inside of IF {...} clauses and FOR and WHILE loops is fixed
-too. Perhaps "unbroken" would be a better word. ckuus5.c, 11 May 2003.
-
-Vace discovered that FTP MGET /EXCEPT:{... (with an unterminated /EXCEPT list)
-could crash Kermit. Fixed in ckcftp.c, 11 May 2003.
-
-CONTINUE should not affect SUCCESS/FAILURE status. ckuusr.c, 11 May 2003.
-
-Fixed an oversight that goes back 15 years. While \{123} is allowed for
-decimal codes, \x{12} and \o{123} were never handled. ckucmd.c, 11 May 2003.
-
-Added support for Red Hat <baudboy.h> and /usr/sbin/lockdev. Supposedly this
-allows Kermit to be installed without setuid or setgid bits and still be able
-to lock and use the serial device. Compiles and starts, but not tested.
-ckcdeb.h, makefile, ckutio.c, ckuus5.c, 16 May 2003.
-
-From Jeff: FTP ASCII send data to host when FTP /SSL was in use was broken.
-ftp_dpl is set to Clear when FTP /SSL is in use. This was causing the data to
-be written to the socket with send() instead of the OpenSSL routines.
-ckcftp.c, ckuath.c, 21 May 2003.
-
-From Jeff: Stuff for Kerberos 524: ckcdeb.h. Fixes for FTP; "FTP ASCII send
-data did not properly compute the end of line translations. On Unix (and
-similar platforms) the end of line was correct for no character sets but
-incorrect when character sets were specified. On Windows/OS2, the end of line
-was correct when character sets were specified and incorrect when they were
-not. On MAC, both were broken. Also, FTP Send Byte counts were incorrect
-when character sets were specified." ckcftp.c. 17 Jun 2003.
-
-From Jeff: fixes to HTTP /AGENT: and /USER: switch action: ckcnet.c ckuus3.c
-ck_crp.c ckcftp.c ckuus2.c ckuusy.c ckuusr.c ckcnet.h, 21 Jun 2003.
-
-From Jeff: Fix SET DIALER BACKSPACE so it can override a previous SET KEY
-(e.g. from INI file): ckuus7.c. Some SSL/TLS updates: ck_ssl.c. HTTP support
-for VMS and other VMS improvements (e.g. a way to not have to hardwire the
-C-Kerit version number into the build script) from Martin Vorlaender:
-ckcnet.h, ckuus[r3].c, ckcdeb.h, ckvtio.c, ckcnet.c, ckvker.com. Built on
-Solaris (gcc/ansi) and SunOS (cc/k&r). The new VMS script tests the VMS
-version and includes HTTP support only for VMS 6.2 or later. 2 Jul 2003.
-
-Tried to build on our last VMS system but it seems to be dead. Looks like a
-head crash (makes really loud noises, boot says DKA0 not recognized) (fooey, I
-just paid good money to renew the VMS license). Tried building at another
-site with:
-
- Process Software MultiNet V4.3 Rev A-X,
- Compaq AlphaServer ES40, OpenVMS AXP V7.3
- Compaq C V6.4-008 on OpenVMS Alpha V7.3
-
-Had to make a few corrections to ckvker.com. But still, compilation of
-ckcnet.c bombs, indicating that the SELECT definition somehow got lost
-somewhere since the 209 release (i.e. no SELECT type is defined so it falls
-thru to "SELECT is required for this code"). But I don't see anything in
-ckcdeb.h or ckcnet.[ch] that would explain this. Not ckvker.com either
-(putting the old one back gives the same result). OK, I give up, maybe it's
-just that I haven't tried building it on MultiNet recently. What about UCX?
-Aha, builds fine there except for warnings about mlook, dodo, and parser in
-ckvfio.c (because of ON_CD) -- I suppose I have #include <ckucmd.h>... (done)
-Anyhow it builds OK and the HTTP code is active and almost works (HTTP OPEN
-works; HTTP GET seems to succeed but creates an empty file every time). Tried
-building under MultiNet at another installation; same bad result.
-
-OK so why won't it build for MultiNet? Comparing ckcnet.c with the 209
-version, not a single #ifdef or #include is changed. Tried building with
-p3="NOHTTP" -- builds OK, aha. Where's the problem? Not ckcnet.h...
-Not ckcdeb.h... OK I give up, will revisit this next time I get time to
-do anything with the code.
-
-Later Jeff said "Martin did not implement VMS networking for the HTTP code.
-All he did was activate the #define HTTP which happens to work because his
-connections are using SSL/TLS connections. http_inc(), http_tol(), etc have
-no support for VMS networking regardless of whether it is UCX or MULTINET.
-The vast majority of HTTP connections are not secured by SSL/TLS. It makes no
-sense to support HTTP on VMS until someone is willing to either do the work or
-pay have the work done to implement VMS networking in that code base." So the
-fix is to not enable HTTP for VMS after all. Removed the CKHTTP definition
-for VMS from ckcdeb.h, 6 Jul 2003.
-
-Fixed ckvfio.c to #include <ckuusr.h> (instead of <ckucmd.h>) to pick up
-missing prototypes. 6 Jul 2003.
-
-From Arthur Marsh: solaris2xg+openssl+zlib+srp+pam+shadow and the corresponding
-Solaris 7 target. makefile, 6 Jul 2003.
-
-Remove duplicate #includes for <sys/stat.h>, <errno.h>, and <ctype.h> from
-ckcftp.c. 6 Jul 2003.
-
-Add -DUSE_MEMCPY to Motorola SV/68 targets because of shuffled #includes in
-ckcftp.c. 8 Jul 2003.
-
-From Jeff: Fix problems mixing SSL and SRP without Kerberos. Plus a few minor
-#define comment changes and a reshuffling of #defines in ckcdeb.h to allow me
-to build on X86 Windows without Kerberos. ckcdeb.h, ck_crp.c, ckuath.c,
-10 Jul 2003.
-
-From Jeff: updated ckuat2.h and ckuath.c, 29 Jul 2003.
-
-Mats Peterson noticed that a very small Latin-1 file would be incorrectly
-identified as UCS-2 by scanfile(). Fixed in ckuusx.c, 29 Jul 2003.
-
-Fixed ACCESS macro definition to account for the fact that FIND is now a
-built-in command. ckermit.ini, 30 Jul 2003.
-
-From Jeff: Fix for typo in urlparse() (svc/hos): ckuusy.c, 18 Aug 2003.
-
-From Jeff: Redhat9 makefile targets (needed for for OpenSSL 0.9.7):
-makefile, 19 Aug 2003.
-
-GREP /NOLIST and /COUNT did too much magic, with some undesirable fallout:
-"GREP /NOLIST /COUNT:x args" printed "file:count" for each file. "GREP
-/COUNT:x /NOLIST args" did not print "file:count", but neither did it set the
-count variable. Removed the magic. Also one of the GREP switches,
-/LINENUMBERS, was out of order. Fixed in ckuus6.c, 20 Aug 2003.
-
-From Jeff: "Reorganizing code to enable building with different subsets of
-options; a few typos corrected as well." ckcdeb.h, ckuver.h (for RH9),
-ckcnet.c, ckuus7.c, ckuus3.c: 24 Aug 2003.
-
-Scanfile misidentified a big PDF file as text because the first 800K of it
-*was* text (most other PDF files were correctly tagged as binary). Fixed
-by adding a check for the PDF signature at the beginning of the file.
-scanfile(): ckuusx.c, 25 Aug 2003.
-
-Ditto for PostScript files, but conservatively. Signature at beginning of
-file must begin with "%!PS-Ado". If it's just "%!" (or something nonstandard
-like "%%Creator: Windows PSCRIPT") we do a regular scan. Also added "*.ps"
-to all binary filename patterns. ckuusx.c, 4 Sep 2003.
-
-Ditto (but within #ifndef NOPCLSCAN) for PCL (<ESC>E) and PJL (<ESC>%) files,
-but no binpatterns (note: ".PCL" is the extension for TOPS-20 EXEC scripts).
-ckuusx.c, 4 Sep 2003.
-
-Added comments about OpenSSL 0.9.7 to all linux+openssl targets.
-makefile, 4 Sep 2003.
-
-From Jeff: Added - #define ALLOW_KRB_3DES_ENCRYPT. When this symbol is defined
-at compilation Kermit will allow non-DES session keys to be used during Telnet
-Auth. These session keys can then be used for Telnet Encrypt. The reason
-this is not compiled on by default is that the MIT Kerberos Telnet does not
-follow the RFC for constructing keys for ENCRYPT DES when the keys are longer
-than 8 bytes in length. ckuath.c, ckuus5.c, 4 Sep 2003.
-
-"ftp mget a b c" succeeded if one or more of the files did not exist, even
-with "set ftp error-action proceed". This is because the server's NLST file
-list does not include any files that don't exist, so the client never even
-tries to get them. Fortunately, the way the code is structured, this one was
-easy to fix. ckcftp.c, 14 Sep 2003.
-
-From Jeff: Corrected code in ckcnet.c to ensure that Reverse DNS Lookups are
-not performed if tcp_rdns is OFF. Fixed ck_krb5_getrealm() to actually return
-the realm of the credentials cache and not the default realm specified in the
-krb5.conf file. Previously krb5_cc_get_principal() was not being called.
-Fixed ck_krb5_is_tgt_valid() to test the TGT in the current ccache and not the
-TGT constructed from the default realm. ckcnet.c, ckuath.c, 14 Sep 2003.
-
-Marco Bernardi noticed that IF DIRECTORY could produce a false positive if
-the argument directory had previously been referenced but then removed. This
-is because of the clever isdir() cache that was added to speed up recursion
-through big directory trees. Changed IF DIRECTORY to make a second check
-(definitive but more expensive) if isdir() succeeds, and changed the
-directory-deleting routine, ckmkdir(), to flush the directory cache (UNIX
-only -- this also should be done in K95 but it's not critical). This was
-done by adding a routine, clrdircache() to ckufio.c, which sets prevstat
-to -1 and prevpath[0] to NUL. ckcfn3.c, ckuus6.c, ckufio.c, 18 Sep 2003.
-
-Marco reported the second fix still didn't work for him (even though it did
-for me). Rather than try to figure out why, I concluded that the directory
-cache is just not safe: a directory found a second ago might have been deleted
-or renamed not only by Kermit but by some other process. Why did I add this
-in the first place? The log says:
-
- Some debug logs showed that isdir() is often called twice in a row on the
- same file. Rather than try to sort out clients, I added a 1-element cache
- to Unix isdir(). ckufio.c, 24 Apr 2000.
-
-Experimentation with DIR and DIR /RECURSIVE does not show this happening at
-all. So I #ifdef'd out the directory cache (see #ifdef ISDIRCACHE in ckufio.c;
-ISDIRCACHE is not defined) and backed off the previous changes: ckufio.c,
-ckcfn3.c, ckuus6.c, 28 Sep 2003.
-
-From Jeff: Replace the compile time ALLOW_KRB_3DES_ENCRYPT with a run-time
-command SET TELNET BUG AUTH-KRB5-DES which defaults to ON: ckctel.[ch],
-ckuus[234].c, ck_crp.c, ckuath.c. 4 Oct 2003.
-
-Allow DIAL RETRIES to be any positive number, and catch negative ones.
-Also added code to check for atoi() errors (e.g. truncation). At least on
-some platforms (e.g. Solaris) atoi() is supposed to set errno, but it
-doesn't. ckuus3.c, ckucmd.c, 4 Oct 2003.
-
-Added /DEFAULT: to ASK-class commands (ASK, ASKQ, GETOK):
-
- . For popups: no way to send defaults to popup_readtext() or popup_readpass().
- . For GUI ASK[Q], pass default to gui_txt_dialog().
- . For GUI GETOK, convert "yes" "ok" or "no" default to number for uq_ok().
- . For Text GETOK, add default to cmkey().
- . For Text ASK[Q], add default to cmtxt().
- . For GETC, GETKEY, and READ: no changes.
-
-GETOK, ASK, and ASKQ with /TIMEOUT: no longer fail when the timer goes off
-if a /DEFAULT was supplied. The GUI functions (uq_blah) don't seem to
-support timeouts. Only the text version has been tested. ckuus[26].c,
-4 Oct 2003.
-
-From Jeff: add /DEFAULT: for popups. ckuus6.c. 6 Oct 2003.
-
-Change SET DIAL INTERVAL to be like SET DIAL RETRIES. ckuus[34].c, 6 Oct 2003.
-
-Added target for HP-UX 10/11 + OpenSSL built with gcc, from Chris Cheney.
-Makefile, 12 Oct 2003.
-
-From Jeff, 6 Nov 2003:
- . #ifdef adjustments: ckcftp.c, ckcdeb.h
- . Fix spurious consumption of first byte(s) on Telnet connection: ckctel.c
- . Another HP PJL test for scanfile: ckuusx.c.
- . K95: Recognize DG4xx protected fields in DG2xx emulation: ckuus7.c.
- . Add SSLeay version display to SHOW AUTH command: ckuus7.c
- . Improved SET MOUSE CLEAR help text: ckuus2.c.
- . Improved Kverbs help text: ckuus2.c (+ new IBM-3151 Kverbs).
- . Some changes to ck_ssl.c, ckuath.c.
-
-From PeterE, 10 Nov 2003:
- . Improved HP-UX 10/11 makefile targets for OpenSSL.
- . #ifdef fix for OpenSSL on HP-UX: ck_ssl.c.
-
-Another new makefile from PeterE with improved and integrated HP-UX targets.
-12 Nov 2003.
-
-A couple fixes to the solaris9g+krb5+krb4+openssl+shadow+pam+zlib target
-from Jeff. Added a solaris9g+openssl+shadow+pam+zlib target. makefile,
-21 Nov 2003.
-
-From Jeff, 30 Nov 2003:
- . Fix SEND /MOVE-TO: ckuusr.c.
- . Fix K95 SET TITLE to allow quotes/braces around text: ckuus7.c.
- . Improved "set term autodownload ?" response: ckuus5.c.
- . Fix SHOW FEATURES to specify the protocol for encryption: ckuus5.c
- . Make {SEND, RECEIVE} {MOVE-TO, RENAME-TO} work for XYZMODEM (K95 only).
-
-From Jeff: 7 Jan 2004:
- . At one point Frank started to add a timer parameter to the
- uq_txt() function but he only did it for the non-ANSI
- compilers. I added it for the ANSI compilers, fixed the
- prototypes and provided a default value easily changed
- DEFAULT_UQ_TIMEOUT: ckcker.h, ckuus[36].c, ck_ssl.c, ckcftp.c, ckuath.c.
- . Fixed SET TERMINAL DEBUG ON (typo in variable name): ckuus7.c.
- . Fixed BEEP INFORMATION; previously it made no sound, now uses
- MB_ICONQUESTION. ckuusx.c.
-
-From Ian Beckwith <ian@nessie.mcc.ac.uk> (Debianization), 7 Jan 2004:
- . Search dir/ckermit for docs, as well as dir/kermit in cmdini(): ckuus5.c.
- . New linux+krb5+krb4+openssl+shadow+pam target (kitchen sink minus SRP,
- which Debian does not distribute): makefile.
- ? Mangles the DESTDIR support in makefile to install into a staging area:
- makefile (I didn't take this one yet).
-
-Updated copyright notices for 2004, all modules. 7 Jan 2004.
-
-Added INPUT /NOMATCH, allowing INPUT to be used for a fixed amount of time
-without attempting to match any text or patterns, so it's no longer
-necessary to "input 600 STRING_THAT_WILL_NEVER_COME". If /NOMATCH is
-included, INPUT succeeds if the timeout expires, with \v(instatus) = 1
-(meaning "timed out"); fails upon interruption or i/o error. ckuusr.h,
-ckuus[r24].c, 7 Jan 2004.
-
-Added SET INPUT SCALE-FACTOR <float>. This scales all INPUT timeouts by the
-given factor, allowing time-sensitive scripts to be adjusted to changing
-conditions such as congested networks or different-speed modems without
-having to change each INPUT-class command. This affects only those timeouts
-that are given in seconds, not as wall-clock times. Although the scale
-factor can have a fractional part, the INPUT timeout is still an integer.
-Added this to SHOW INPUT, and added a \v(inscale) variable for it.
-ckuusr.h, ckuus[r257].c, 7 Jan 2004.
-
-undef \%a, \fverify(abc,\%a) returns 0, which makes it look as if \%a is a
-string composed of a's, b's, and/or c's, when in fact it contains nothing.
-Changed \fverify() to return -1 in this case. ckuus4.c, 12 Jan 2004.
-
-\fcode(xxx) returned an empty string if its argument string was empty. This
-makes it unsafe to use in arithmetic or boolean expressions. Changed it to
-return 0 if its argument was missing, null, or empty. ckuus4.c, 12 Jan 2004.
-
-Updated \verify() and \fcode() help text. ckuus2.c, 12 Jan 2004.
-
-While setting up IKSD, Ian Beckwith noticed that including the --initfile:
-option caused Kermit to start parsing its own Copyright string as if it were
-the command line, and eventually crash. I couldn't reproduce on Solaris /
-Sparc but I could in Linux / i386 (what Ian is using) -- a change from Jeff
-on 28 Apr 2003 set the command-line arg pointer to a literal empty string in
-prescan() about line 1740 of of ckuus4.c; the pointer is incremented next
-time thru the loop, resulting in random memory being referenced. Fixed by
-setting the pointer to NULL instead of "". ckuus4.c, 12 Jan 2004.
-
-declare \&a[999999999999999] would dump core on some platforms. atoi()
-or whatever would truncate the dimension to maxint. When we add 1 to the
-result, we get a negative number, which is used as an index, loop test, etc.
-Fixed both dodcl() and dclarray() to check for (n+1 < 0). ckuus[r5].c,
-12 Jan 2004.
-
-Unix zchki() would fail on /dev/tty, which is unreasonable. This prevented
-FOPEN /READ from reading from the terminal. zchki() already allowed for
-/dev/null, so I added /dev/tty to the list of specials. Ditto for FOPEN
-/WRITE and zchko(). ckufio.c 13 Jan 2004.
-
-Added untabify() routine to ckclib.[ch], 13 Jan 2004.
-Added FREAD /TRIM and /UNTABIFY. ckuus[27].c, 13 Jan 2004.
-Added \funtabify(). ckuusr.h, ckuus[24].c, 13 Jan 2004.
-
-Dat Nguyen noticed that (setq u 'p') followed by (u) dumped core. This was
-caused by an over-clever optimization that skipped mallocs for short
-literals, but then went on later to try to free one that hadn't been
-malloc'd. Fixed in dosexp(): ckuus3.c, 14 Jan 2004.
-
-Catch another copyright date. ckuus5.c, 14 Jan 2004.
-
-Fixed SWITCH to work even when SET COMMAND DOUBLEQUOTE OFF (from Mark
-Sapiro). ckuus5.c, 15 Jan 2004.
-
-Changed version to 8.0.211 so scripts can test for recently added features.
-ckcmai.c, 15 Jan 2004.
-
-Fixed a glitch in K95 "help set port". ckuus2.c, 20 Jan 2004.
-
-Fix from Jeff: Connections to a TLS-aware protocol which require a reconnect
-upon certificate verification failure could not reconnect if the connection
-was initiated from the command line or via a URL. ckctel.c ckcmai.c
-ckuusr.c ckuus7.c ckuusy.c, 20 Jan 2004.
-
-From Alex Lewin: makefile target and #ifdef for Mac OS X 10.3 (Panther):
-makefile, ckcnet.c, 7 Feb 2004.
-
-Added KFLAGS to sco32v507 targets to make PTY and SSH commands work. The
-same flags could probably also be added to earlier OSR5 targets but they
-have not been tested there. makefile, 7 Feb 2004.
-
-Checked a complaint that "LOCAL &a" did not make array \&a[] local. Indeed
-it did not, and can not. You have to use the full syntax in the LOCAL
-command, "LOCAL \&a[]", or else it doesn't know it's not a macro named &a.
-7 Feb 2004.
-
-Fixed some confusion in creating IKSD database file and temp-file names.
-I was calling zfnqfp() without remembering that the path member of the
-returned struct included the filename, so to get just the directory name,
-I needed to strip the filename from the right. ckuusy.c, 2 Mar 2004.
-
-New ckuath.c, ck_ssl.c from Jeff. 2 Mar 2004.
-
-Updated Jeff's affiliation in VERSION command text. ckuusr.c, 2 Mar 2004.
-
-Designation changed from Dev.00 to Beta.01. ckcmai.c, 2 Mar 2004.
-
-Fixed zrename() syslogging -- it had success and failure reversed.
-Beta.02: ckufio.c, 4 Mar 2004.
-
-Problem: when accessing IKSD via a kermit:// or iksd:// URL, and a user ID
-is given but no password, doxarg() set the password to "" instead of leaving
-it NULL, but all the tests in dourl() are for NULL. Fixed in doxarg():
-ckuusy.c, 5 Mar 2004.
-
-The logic in dourl() about which macro to construct (login and connect,
-login and get directory listing, or login and fetch a file) was a bit off,
-so all three cases were not handled. ckcmai.c, 5 Mar 2004.
-
-Trial Beta builds:
- . HP-UX B.11.11 PA-RISC
- . HP-UX B.11.23 IA64
- . Tru64 4.0G Alpha
- . Tru64 5.1B Alpha
- . Debian 3.0 i386
- . Red Hat ES 2.1 i386
- . Slackware 9.1 i386
- . VMS 7.3-1 Alpha + UCX 5.3
- . VMS 7.3-1 Alpha no TCP/IP
- . VMS 7.3 Alpha MultiNet 4.3 A-X
- . SCO UnixWare 7.1.4 i386
- . SCO OSR5.0.7 i386
- . Solaris 9 Sparc
-
-Fixed compiler warning in doxarg() caused by typo (NULL instead of NUL) in
-the 5 March doxarg() edit. ckuusy.c, 9 Mar 2004.
-
-IKSD (kermit://) command-line URLs did not work right if the client had
-already preauthenticated with Kerberos or somesuch because they tried to log
-in again with REMOTE LOGIN. The macros constructed in doxarg() needed to
-check \v(authstate) before attempting REMOTE LOGIN. ckcmai.c, 10 Mar 2004.
-
-Added ckuker.nr to x.sh (ckdaily upload) and updated ckuker.nr with current
-version number and dates. 10 Mar 2004.
-
-Replaced hardwired references to /usr/local in makefile with $(prefix)
-(which defaults to /usr/local, but can be overridden on the command line),
-suggested by Nelson Beebe for use with Configure. 10 Mar 2004.
-
-From Nelson Beebe: In the Kermit makefile in the install target commands,
-line 981 reads:
-
- cp $(BINARY) $(DESTDIR)$(BINDIR)/kermit || exit 1;\
-
-Could you please add this line before it:
-
- rm -f $(DESTDIR)$(BINDIR)/kermit;\
-
-Some sites (mine included) keep multiple versions of software around,
-with hard links between $(prefix)/progname and $(prefix)/progname-x.y.z.
-Failure to remove the $(prefix)/progname at "make install" time then
-replaces the old $(prefix)/progname-x.y.z with the new one, destroying
-an old version that the site wanted to be preserved. makefile, 10 Mar 2004.
-
-Minor syntax and typo fixes (mostly prototypes): ckcdeb.h, ckcfns.c,
-ckclib.c, ckufio.c, ckuusr.h, ckuusx.c, 10 Mar 2004. (I still have a few
-more to do.)
-
-Added CC=$(CC) CC2=$(CC2) to many (but not all) makefile targets that
-reference other makefile targets. On some platforms (notably AIX, Solaris,
-SunOS) there are specific targets for different compilers, so I skipped
-those. makefile, 10 Mar 2004.
-
-Added error checking to kermit:// URL macros, so they don't plow ahead
-after the connection is closed. ckcmai.c, 11 Mar 2004.
-
-Added FreeBSD 4.9 and 5.1 targets (only the herald is affected).
-makefile, ckuver.h, 11 Mar 2004.
-
-Added "LIBS=-lcrypt" to bsd44 targets since nowadays crypt is almost always
-unbundled from libc. Also added explanatory notes. makefile, 11 Mar 2004.
-
-Changed MANDIR to default to $(manroot)/man/man1, and manroot to default
-to $(prefix). More adding of CC=$(CC) clauses: {Free,Net,Open}BSD, 4.4BSD.
-makefile, 11 Mar 2004.
-
-Miscellaneous cleanups: ckuusx.c, ckcnet.c, ckufio.c, 11 Mar 2004.
-
-Corrected the check in the linux target to see if /usr/include/crypt.h
-exists, and if so to define HAVE_CRYPT_H, which is used in ckcdeb.h to
-#include <crypt.h> to get the prototype for crypt() and prevent bogus
-conversions on its return type on 64-bit platforms (the previous test wasn't
-quite right and the resulting symbol wasn't spelled right). makefile,
-12 Mar 2004.
-
-From Jeff, 14 Mar 2004:
- . Initialize localuidbuf[] in tn_snenv(): ckctel.c.
- . Remove remote-mode checks in hupok() for K95G only (why?): ckuus3.c.
- . Add help text for new K95-only TYPE /GUI switches: ckuus2.c.
- . TYPE /GUI parsing, ...: ckuusr.c.
- . TYPE /GUI action, dotype(): ckuus6.c
- . Change Jeff's affiliation: most modules.
-
-20 Mar 2004: Looked into adding long file support, i.e. handling files more
-than 2GB (or 4GB) long. Discovered very quickly this would be a major
-project. Each platform has a different API, or environment, or transition
-plan, or whatever -- a nightmare to handle in portable code. At the very
-least we'll need to convert a lot of Kermit variables from long or unsigned
-long to some new Kermit type, which in turn is #defined or typedef'd
-appropriately for each platform (to off_t or size_t or whatever). Then we
-have to worry about the details of open() vs fopen(); printf() formats (%lld
-vs %Ld vs %"PRId64"...), platforms like HP-UX where you might have to use
-different APIs for different file systems on the same computer, etc. We'll
-need to confront this soon, but let's get a good stable 8.0.211 release out
-first! Meanwhile, for future reference, here are a few articles:
-
-General: http://freshmeat.net/articles/view/709/
-Linux: http://www.ece.utexas.edu/~luo/linux_lfs.html
-HP-UX: http://devrsrc1.external.hp.com/STK/partner/lg_files.pdf
-Solaris: http://wwws.sun.com/software/whitepapers/wp-largefiles/largefiles.pdf
-
-Looked into FTP timeouts. It appears I can just call empty() (which is
-nothing more than a front end for select()) with the desired timeout before
-any kind of network read. If it returns <= 0, we have a timeout. This is
-not quite the same as using alarm() / signal() around a recv() (which could
-get stuck) but alarm() / signal() are not not used in the FTP module and are
-not naturally portable to Windows, but select() is already in use in the FTP
-module for both Unix and Windows. This form of timeout could be used
-portably for both command response and data reads. What about writes to the
-command or data socket? They can get stuck for hours and hours without
-returning too, but the select() approach won't help here -- we need the
-actual send() or recv() to time out, or be wrapped in an alarm()/signal()
-kind of mechanism. But if we can do that for sends, we can also do it for
-receives. Better check with Jeff before I start programming anything.
-20 Mar 2004.
-
-Later: Decided to postpone the above two projects (ditto IPv6) until after
-8.0.211 is released because both will have major impacts on portability.
-Grumble: all i/o APIs should have been designed from the beginning with a
-timeout parameter. To this day, hardly any have this feature.
-
-3-4 Apr 2004: More 8.0.211 Beta.02+ test builds:
-
- . FreeBSD 3.3
- . FreeBSD 4.4
- . Linux Debian 2.1
- . Linux RH 6.1
- . Linux RH 7.1
- . Linux RH 7.2
- . Linux RH 9 (with 84 different combinations of feature selection)
- . Linux SuSE 6.4
- . Linux SuSE 7.0
- . NetBSD 1.4.1
- . NetBSD 1.5.2
- . OpenBSD 2.5
- . OpenBSD 3.0
- . QNX 4.25
- . SCO UnixWare 2.1.3
- . SCO UnixWare 7.1.4
- . SCO OpenServer 5.0.7
- . SCO XENIX 2.3.4 (no TCP)
-
-Changes needed: None.
-
-Problem: SCO XENIX 2.3.4 network build failed in the FTP module with
-header-file syntax and conflicting-definitions trouble. I'm not going to
-try to fix it; 8.0.209 built OK with FTP, so we'll just keep that one
-available.
-
-Got access to VMS 8.1 on IA64. Building the nonet version of C-Kermit
-required minor modifications to ckvvms.h, ckv[ft]io.c, and ckvcon.c, to
-account for a third architecture. Also to SHOW FEATURES in ckuus5.c. Once
-that was done, the UCX 5.5 version built OK too. Starts OK, makes Telnet
-connection OK, sends files. Has some obvious glitches though -- "stat"
-after a file transfer reports 0 elapsed time (in fact it was 00:09:48) and
-1219174400 cps (when in fact it was 10364). This doesn't happen on the
-Alpha. Btw, the IA64 binary is twice as big as the Alpha one. Changed
-to Beta.03. 5 Apr 2004.
-
-Fixed the ckdaily script to include the makefile and man page in the Zip
-file (they were not included because the Zip file was intended mainly for
-VMS users, but some Unix users prefer Zip to tar.gz). 6 Apr 2004.
-
-Traced problems in VMS/IA64 statistics report to rftimer()/gftimer() in
-ckvtio.c, which use sys$ and lib$ calls to figure elapsed time. These work
-on VAX and Alpha but not IA64. Sent a report to the chief engineer of the
-IA64 VMS port; he says it's probably a bug in VMS 8.1 (which is not a real
-release); he'll make sure it's fixed in 8.2. As an experiment, tried
-swapping in the Unix versions of these routines (which call gettimeofday()
-etc). They seem work just fine (it hung a couple times but I think that's
-because the underlying system hung too; trying it later on a new connection,
-it was fine; however I noticed a BIG discrepancy in throughput between
-sending and receiving). Moved definitions for VMS64BIT and VMSI64 to
-ckcdeb.h so all modules can use them and added them to the SHOW FEATURES
-display. Added VMSV80 definition to build procedure. Beta.03+. ckcdeb.h,
-ckcuus5.c, ckcvvms.h, ckvtio.c, ckvker.com, 6 Apr 2004.
-
-While doing the build-all, I noticed the VMS version did not build with
-Multinet or older UCX versions, always with the same errors -- undeclared
-variables, undefined symbols, all TCP/IP related. This didn't happen a
-couple weeks ago... Somehow the order of #includes was messed up --
-ckuusr.h depended on symbols that are defined in ckcnet.h, but ckcnet.h
-was being included after ckuusr.h... this was compounded by two missing
-commas in ckvker.com. 11 Apr 2004.
-
-Removed Beta designation, released as 8.0.211, 10 Apr 2004.
-
----8.0.211---
-
-I had somehow lost the edit to ckutio.c that changed the UUCP lockfile for
-Mac OS X from /var/spool/uucp to /var/spool/lock. So I slipped it in and
-re-uploaded version 8.0.211. You can tell the difference because SHOW
-VERSIONS has a 17 Apr 2004 for the Communications I/O module. Also the 10.3
-executable now has a designer banner: "Mac OS X 10.3". makefile, ckuver.h,
-ckutio.c, ckuus[45].c, 17 Apr 2004.
