+
+ * regex.c: Do not include <sys/types.h>, as POSIX no longer
+ requires this. (The code never needed it.)
+
+ * regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
+ All uses of recently-renamed identifiers changed to use the new,
+ POSIX-compliant names. The code will build and run just fine
+ without these changes, but it's better to eat our own dog food
+ and use the standard-conforming names.
+
+ * regex.h: Fix a multitude of POSIX name space violations.
+ These changes have an effect only for programs that define
+ _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
+ do not change anything for programs compiled in the normal way.
+ Also, there is no effect on the ABI.
+
+ (_REGEX_SOURCE): New macro.
+ Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
+ defined and _GNU_SOURCE is not; this fixes a name space violation.
+
+ Rename the following macros to obey POSIX requirements.
+ The old names are still visible as macros if _REGEX_SOURCE is defined.
+ (REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
+ RE_BACKSLASH_ESCAPE_IN_LISTS.
+ (REG_BK_PLUS_QM): renamed from RE_BK_PLUS_QM.
+ (REG_CHAR_CLASSES): renamed from RE_CHAR_CLASSES.
+ (REG_CONTEXT_INDEP_ANCHORS): renamed from RE_CONTEXT_INDEP_ANCHORS.
+ (REG_CONTEXT_INDEP_OPS): renamed from RE_CONTEXT_INDEP_OPS.
+ (REG_CONTEXT_INVALID_OPS): renamed from RE_CONTEXT_INVALID_OPS.
+ (REG_DOT_NEWLINE): renamed from RE_DOT_NEWLINE.
+ (REG_DOT_NOT_NULL): renamed from RE_DOT_NOT_NULL.
+ (REG_HAT_LISTS_NOT_NEWLINE): renamed from RE_HAT_LISTS_NOT_NEWLINE.
+ (REG_INTERVALS): renamed from RE_INTERVALS.
+ (REG_LIMITED_OPS): renamed from RE_LIMITED_OPS.
+ (REG_NEWLINE_ALT): renamed from RE_NEWLINE_ALT.
+ (REG_NO_BK_BRACES): renamed from RE_NO_BK_BRACES.
+ (REG_NO_BK_PARENS): renamed from RE_NO_BK_PARENS.
+ (REG_NO_BK_REFS): renamed from RE_NO_BK_REFS.
+ (REG_NO_BK_VBAR): renamed from RE_NO_BK_VBAR.
+ (REG_NO_EMPTY_RANGES): renamed from RE_NO_EMPTY_RANGES.
+ (REG_UNMATCHED_RIGHT_PAREN_ORD): renamed from
+ RE_UNMATCHED_RIGHT_PAREN_ORD.
+ (REG_NO_POSIX_BACKTRACKING): renamed from RE_NO_POSIX_BACKTRACKING.
+ (REG_NO_GNU_OPS): renamed from RE_NO_GNU_OPS.
+ (REG_DEBUG): renamed from RE_DEBUG.
+ (REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
+ (REG_IGNORE_CASE): renamed from RE_ICASE. This renaming is a bit
+ unusual, since we can't clash with the POSIX REG_ICASE.
+ (REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
+ (REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
+ (REG_NO_SUB): renamed from RE_NO_SUB.
+ (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.
+ (REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.
+ (REG_SYNTAX_GNU_AWK): renamed from RE_SYNTAX_GNU_AWK.
+ (REG_SYNTAX_POSIX_AWK): renamed from RE_SYNTAX_POSIX_AWK.
+ (REG_SYNTAX_GREP): renamed from RE_SYNTAX_GREP.
+ (REG_SYNTAX_EGREP): renamed from RE_SYNTAX_EGREP.
+ (REG_SYNTAX_POSIX_EGREP): renamed from RE_SYNTAX_POSIX_EGREP.
+ (REG_SYNTAX_ED): renamed from RE_SYNTAX_ED.
+ (REG_SYNTAX_SED): renamed from RE_SYNTAX_SED.
+ (_REG_SYNTAX_POSIX_COMMON): renamed from _RE_SYNTAX_POSIX_COMMON.
+ (REG_SYNTAX_POSIX_BASIC): renamed from RE_SYNTAX_POSIX_BASIC.
+ (REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from
+ RE_SYNTAX_POSIX_MINIMAL_BASIC.
+ (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
+ (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
+ RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
+ (REG_DUP_MAX): renamed from RE_DUP_MAX. No need to undef it.
+ (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
+ (REG_REALLOCATE): Renamed from REGS_REALLOCATE.
+ (REG_FIXED): Renamed from REGS_FIXED.
+ (REG_NREGS): Renamed from RE_NREGS.
+
+ (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
+ of other REG_* macros, since POSIX says the user is allowed to
+ #undef these macros selectively.
+
+ (reg_errcode_t): Update comment stating what other tables need
+ to be consistent.
+
+ Rename the following enum values to obey POSIX requirements.
+ The old names are still visible as macros.
+ (_REG_ENOSYS): Renamed from REG_ENOSYS. Define even if _XOPEN_SOURCE
+ is not defined, since GNU is supposed to be a superset of POSIX as
+ much as possible, and since we want reg_errcode_t to be a signed
+ type for implementation consistency.
+ (_REG_NOERROR): Renamed from REG_NOERROR.
+ (_REG_NOMATCH): Renamed from REG_NOMATCH.
+ (_REG_BADPAT): Renamed from REG_BADPAT.
+ (_REG_ECOLLATE): Renamed from REG_ECOLLATE.
+ (_REG_ECTYPE): Renamed from REG_ECTYPE.
+ (_REG_EESCAPE): Renamed from REG_EESCAPE.
+ (_REG_ESUBREG): Renamed from REG_ESUBREG.
+ (_REG_EBRACK): Renamed from REG_EBRACK.
+ (_REG_EPAREN): Renamed from REG_EPAREN.
+ (_REG_EBRACE): Renamed from REG_EBRACE.
+ (_REG_BADBR): Renamed from REG_BADBR.
+ (_REG_ERANGE): Renamed from REG_ERANGE.
+ (_REG_ESPACE): Renamed from REG_ESPACE.
+ (_REG_BADRPT): Renamed from REG_BADRPT.
+ (_REG_EEND): Renamed from REG_EEND.
+ (_REG_ESIZE): Renamed from REG_ESIZE.
+ (_REG_ERPAREN): Renamed from REG_ERPAREN.
+ (REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE):
+ (REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
+ (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
+ (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.
+
+ (_REG_RE_NAME, _REG_RM_NAME): New macros.
+ (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE. All uses
+ changed. But support the old name if the new one is not defined
+ and if _REGEX_SOURCE.
+
+ Change the following member names in struct re_pattern_buffer.
+ The old names are still supported if !_REGEX_SOURCE.
+ The new names are always supported, regardless of _REGEX_SOURCE.
+ (re_buffer): Renamed from buffer.
+ (re_allocated): Renamed from allocated.
+ (re_used): Renamed from used.
+ (re_syntax): Renamed from syntax.
+ (re_fastmap): Renamed from fastmap.
+ (re_translate): Renamed from translate.
+ (re_can_be_null): Renamed from can_be_null.
+ (re_regs_allocated): Renamed from regs_allocated.
+ (re_fastmap_accurate): Renamed from fastmap_accurate.
+ (re_no_sub): Renamed from no_sub.
+ (re_not_bol): Renamed from not_bol.
+ (re_not_eol): Renamed from not_eol.
+ (re_newline_anchor): Renamed from newline_anchor.
+
+ Change the following member names in struct re_registers.
+ The old names are still supported if !_REGEX_SOURCE.
+ The new names are always supported, regardless of _REGEX_SOURCE.
+ (rm_num_regs): Renamed from num_regs.
+ (rm_start): Renamed from start.
+ (rm_end): Renamed from end.
+
+ (re_set_syntax, re_compile_pattern, re_compile_fastmap):
+ (re_search, re_search_2, re_match, re_match_2, re_set_registers):
+ Prepend __ to parameter names.
+
+ Undo yesterday's changes.
