| New in alpha3.8: Bug fix for signed/unsigned mixup, found and fixed |
| by the FreeBSD folks. |
| |
| New in alpha3.7: A bit of cleanup aimed at maximizing portability, |
| possibly at slight cost in efficiency. "ul" suffixes and "unsigned long" |
| no longer appear, in particular. |
| |
| New in alpha3.6: A couple more portability glitches fixed. |
| |
| New in alpha3.5: Active development of this code has been stopped -- |
| I'm working on a complete reimplementation -- but folks have found some |
| minor portability glitches and the like, hence this release to fix them. |
| One penalty: slightly reduced compatibility with old compilers, because |
| the ANSI C `unsigned long' type and `ul' constant suffix are used in a |
| few places (I could avoid this but it would be considerably more work). |
| |
| New in alpha3.4: The complex bug alluded to below has been fixed (in a |
| slightly kludgey temporary way that may hurt efficiency a bit; this is |
| another "get it out the door for 4.4" release). The tests at the end of |
| the tests file have accordingly been uncommented. The primary sign of |
| the bug was that something like a?b matching ab matched b rather than ab. |
| (The bug was essentially specific to this exact situation, else it would |
| have shown up earlier.) |
| |
| New in alpha3.3: The definition of word boundaries has been altered |
| slightly, to more closely match the usual programming notion that "_" |
| is an alphabetic. Stuff used for pre-ANSI systems is now in a subdir, |
| and the makefile no longer alludes to it in mysterious ways. The |
| makefile has generally been cleaned up some. Fixes have been made |
| (again!) so that the regression test will run without -DREDEBUG, at |
| the cost of weaker checking. A workaround for a bug in some folks' |
| <assert.h> has been added. And some more things have been added to |
| tests, including a couple right at the end which are commented out |
| because the code currently flunks them (complex bug; fix coming). |
| Plus the usual minor cleanup. |
| |
| New in alpha3.2: Assorted bits of cleanup and portability improvement |
| (the development base is now a BSDI system using GCC instead of an ancient |
| Sun system, and the newer compiler exposed some glitches). Fix for a |
| serious bug that affected REs using many [] (including REG_ICASE REs |
| because of the way they are implemented), *sometimes*, depending on |
| memory-allocation patterns. The header-file prototypes no longer name |
| the parameters, avoiding possible name conflicts. The possibility that |
| some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is |
| now handled gracefully. "uchar" is no longer used as an internal type |
| name (too many people have the same idea). Still the same old lousy |
| performance, alas. |
| |
| New in alpha3.1: Basically nothing, this release is just a bookkeeping |
| convenience. Stay tuned. |
| |
| New in alpha3.0: Performance is no better, alas, but some fixes have been |
| made and some functionality has been added. (This is basically the "get |
| it out the door in time for 4.4" release.) One bug fix: regfree() didn't |
| free the main internal structure (how embarrassing). It is now possible |
| to put NULs in either the RE or the target string, using (resp.) a new |
| REG_PEND flag and the old REG_STARTEND flag. The REG_NOSPEC flag to |
| regcomp() makes all characters ordinary, so you can match a literal |
| string easily (this will become more useful when performance improves!). |
| There are now primitives to match beginnings and ends of words, although |
| the syntax is disgusting and so is the implementation. The REG_ATOI |
| debugging interface has changed a bit. And there has been considerable |
| internal cleanup of various kinds. |
| |
| New in alpha2.3: Split change list out of README, and moved flags notes |
| into Makefile. Macro-ized the name of regex(7) in regex(3), since it has |
| to change for 4.4BSD. Cleanup work in engine.c, and some new regression |
| tests to catch tricky cases thereof. |
| |
| New in alpha2.2: Out-of-date manpages updated. Regerror() acquires two |
| small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges |
| in my own test program and might be useful to others for similar purposes. |
| The regression test will now compile (and run) without REDEBUG. The |
| BRE \$ bug is fixed. Most uses of "uchar" are gone; it's all chars now. |
| Char/uchar parameters are now written int/unsigned, to avoid possible |
| portability problems with unpromoted parameters. Some unsigned casts have |
| been introduced to minimize portability problems with shifting into sign |
| bits. |
| |
| New in alpha2.1: Lots of little stuff, cleanup and fixes. The one big |
| thing is that regex.h is now generated, using mkh, rather than being |
| supplied in the distribution; due to circularities in dependencies, |
| you have to build regex.h explicitly by "make h". The two known bugs |
| have been fixed (and the regression test now checks for them), as has a |
| problem with assertions not being suppressed in the absence of REDEBUG. |
| No performance work yet. |
| |
| New in alpha2: Backslash-anything is an ordinary character, not an |
| error (except, of course, for the handful of backslashed metacharacters |
| in BREs), which should reduce script breakage. The regression test |
| checks *where* null strings are supposed to match, and has generally |
| been tightened up somewhat. Small bug fixes in parameter passing (not |
| harmful, but technically errors) and some other areas. Debugging |
| invoked by defining REDEBUG rather than not defining NDEBUG. |
| |
| New in alpha+3: full prototyping for internal routines, using a little |
| helper program, mkh, which extracts prototypes given in stylized comments. |
| More minor cleanup. Buglet fix: it's CHAR_BIT, not CHAR_BITS. Simple |
| pre-screening of input when a literal string is known to be part of the |
| RE; this does wonders for performance. |
| |
| New in alpha+2: minor bits of cleanup. Notably, the number "32" for the |
| word width isn't hardwired into regexec.c any more, the public header |
| file prototypes the functions if __STDC__ is defined, and some small typos |
| in the manpages have been fixed. |
| |
| New in alpha+1: improvements to the manual pages, and an important |
| extension, the REG_STARTEND option to regexec(). |
