a small amount of unused stuff (by the bmakefiles to follow), but it isn't much and seems harmless enough.

|
||

|
||
|
||
Tue May 23 12:11:28 1995 Per Bothner <bothner@kalessin.cygnus.com>
|
||
|
||
* rx.c (regcomp and other POSX.2 functions): Leave them out for
|
||
now, because they conflict with Motif on HPUX.
|
||
|
||
* rx.c (re_syntax_table): Only declare #ifndef RX_WANT_RX_DEFS;
|
||
otherwise we duplicate the declaration in rx.h.
|
||
* rx.c (re_search_2_fetch_char): Add missing cast.
|
||
|
||
Sun Apr 2 23:24:52 1995 Tom Lord <lord@x1.cygnus.com>
|
||
|
||
* rx.h (rx_search): check for and propogate internal
|
||
errors correctly (bogus check sometimes mistook ok returns
|
||
for internal errors).
|
||
|
||
Sun Feb 12 19:28:22 1995 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.h (rx_search):
|
||
From: hankedr@duc.auburn.edu (Darrel Hankerson)
|
||
2. I have some problems understanding the code which sets
|
||
search_state.free_chunks=0. It appears to me that since this is used
|
||
to track alloca'd mem, that it should be done once at the top of
|
||
rx_search(). Indeed, this also fixes the problem in the tests I'm
|
||
running, but I don't have confidence in this "solution".
|
||
[looks right to me. -tl]
|
||
|
||
|
||
* rx.c: Two reported by kwzh.
|
||
|
||
(re_search_2_get_burst): in the two string case,
|
||
when computing `inset', add in pos->offset.
|
||
|
||
(re_search_2_fetch_char): watch for the case when
|
||
pos is just to the left of the second string, pos refers
|
||
to the second string, but the first string is provided.
|
||
This can happen at the very beginning of a match when the
|
||
first thing after matching the priming character is a side
|
||
effect like re_se_wordend.
|
||
|
||
* rx.h (rx_search): patches (marked by /*|*/)
|
||
from From: hjl@nynexst.com (H.J. Lu). One fixes a clear
|
||
bug in a loop termination test. The other i'm not sure about
|
||
yet, but it doesn't break the sed tests.
|
||
|
||
* rx.c (re_compile_pattern):
|
||
Initialize buf.rx.cset_size.
|
||
(Fixes problem report from Kayvan Sylvan <kayvan@satyr.Sylvan.COM>)
|
||
|
||
* rx.c (#define RX_DECL): cleaned up handling of this macro.
|
||
|
||
* rx.c (re_comp):
|
||
From hjl@nynexst.com
|
||
Define _GNU_SOURCE.
|
||
Test for USE_BSD_REGEX around teh BSD entry points.
|
||
Under BSD, treat the empty-string pattern like the NULL pattern.
|
||
Also under BSD, rx_syntax_options --> re_syntax_options.
|
||
Also, rx_exec --> re_exec and rx_registers --> re_registers.
|
||
|
||
|
||
* rx.c (rx_compile):
|
||
From: kwzh@gnu.ai.mit.edu (Karl Heuer)
|
||
The `\sX' handler ends with `goto append_node' but without setting
|
||
the `append' variable first. This patch should fix it.
|
||
|
||
|
||
* rx.c (regcomp): explicitly zero the field syntax_parens.
|
||
Reported/fix suggested by Morten Holmqvist <netrom@find2.denet.dk>.
|
||
|
||
* rx.h (changes under and around ifdef emacs):
|
||
From: kwzh@gnu.ai.mit.edu (Karl Heuer)
|
||
Here's a patch (for 0.06) to fix most of the other problems I
|
||
mentioned. Some of the cpp conditionals in rx.h were ending at
|
||
the wrong place and/or were incorrectly commented; fixing these
|
||
took care of some of the missing declarations.
|
||
|
||
(fastmap_search): unnecessary defaults to switch statements
|
||
to shut-up "gcc -Wall".
|
||
|
||
Thu Nov 24 18:39:42 1994 Tom Lord (lord@x1.cygnus.com)
|
||
These fixes let's rx pass the spencer.tests from grep.
|
||
|
||
* rx.h (rx_search): moved slightly out of date debugging
|
||
code from RX_DEBUG to RX_DEBUG_0.
|
||
|
||
* rx.h (rx_search): in the outer loop, if get_burst returns
|
||
that there are no more characters, consider the possibility
|
||
of an empty match before failing.
|
||
|
||
* rx.h (rx_search): when computing search_end, don't waste
|
||
time computing MIN and MAX of values already forced into range.
|
||
|
||
* rx.h (rx_search): when making RANGE fit within TOTAL_SIZE,
|
||
don't forget to allow the possible empty match at the end of
|
||
string.
|
||
|
||
* rx.c (is_anchored): the equations solving side-effect
|
||
anchoring were wrong for the r_alternate case. The interesting
|
||
thing about this bug is that it disguises itself as a precedent
|
||
bug between | and ^ because of an optimization in the search
|
||
function that checks rxb->begbuf_only (a return value of is_anchored).
|
||
|
||
* rx.c: Fix the print-name rx_se_win (missing comma).
|
||
Fix the function print_cset to print non-printable characters
|
||
as octal.
|
||
|
||
Sat Nov 5 20:01:46 1994 Jason Merrill (jason@phydeaux.cygnus.com)
|
||
|
||
* Makefile.in (LIBCFLAGS): New variable.
|
||
(.c.o): Use it.
|
||
|
||
Thu Sep 1 16:23:21 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.c: applied patches from H J Lu to unrot BSD compatibility
|
||
code.
|
||
|
||
Mon Aug 29 16:48:57 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
|
||
|
||
* Makefile.in (AR_FLAGS): Define.
|
||
(librx.a): Use $(AR) and $(AR_FLAGS).
|
||
|
||
Fri Aug 26 11:37:36 1994 Ian Lance Taylor (ian@cygnus.com)
|
||
|
||
* configure.in: Call AC_PROG_CPP explicitly.
|
||
* configure: Rebuilt.
|
||
|
||
Thu Aug 25 18:19:47 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.[ch], configure.in: use __const__ instead of
|
||
AC_CONST. Only include stdio once. Don't check
|
||
for memory.h.
|
||
|
||
Tue Aug 16 12:12:01 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.[ch]: LGPL instead of GPL
|
||
|
||
Mon Aug 15 16:24:16 1994 Per Bothner (bothner@kalessin.cygnus.com)
|
||
|
||
* rx.h (rx_search): When checking if we've gotten to the end,
|
||
handle the case that we're searching backwards.
|
||
|
||
Tue Jun 21 12:40:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
|
||
|
||
* rx.c (re_rx_search): New function, exports rx_search.
|
||
|
||
* Makefile.in (clean): Also remove librx.a.
|
||
|
||
Fri Jun 3 12:16:45 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.c(re_search_2_fetch_char): fixed a bug that caused it to
|
||
ignore OFFSET.
|
||
|
||
Thu May 26 14:05:17 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.[ch]: From: Michael Rendell <michael@maple.cs.mun.ca>
|
||
|
||
``The problem seems to lie in the casting between pointers and
|
||
integers (pointers on the alpha are 64 bits, ints 32 bits, longs
|
||
64 bits). The core dump happens in rx_compactify_nfa(), in the
|
||
first for loop in the while(eclose) loop -- rx_hash_find() returns
|
||
0, which is dereferenced.''
|
||
|
||
The patch changed the type of rx_hash_masks to long and
|
||
also a use of `int' to hold a side effect in rx_search.
|
||
|
||
Sat May 14 00:45:14 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.c, rx.h: rearranged all the code
|
||
so that all the rx functions can be exported
|
||
or hidden (define RX_WANT_RX_DEFS when compiling
|
||
and when including rx.h).
|
||
|
||
Wed May 11 01:15:56 1994 Tom Lord (lord@rtl.cygnus.com)
|
||
|
||
* rx.c, rx.h: added rx_search -- searching in
|
||
arbitrarily fragmented strings, continuation support.
|
||
|
||
Wed May 4 13:56:55 1994 Tom Lord (lord@rtl.cygnus.com)
|
||
|
||
* rx.c, rx.h: Started independent maintainence
|
||
of these.

|

|

Fri May 13 02:31:13 1994 Tom Lord (lord@x1.cygnus.com)
|
||
|
||
* rx.c: eliminated the weirdo custom allocators.
|
||
Fixed some bugs (but lost the ChangeLog entries).
|
||
|
||
Wed May 11 06:09:31 1994 Chip Salzenberg (chip@fin.uucp)
|
||
|
||
* rx.c (rx_superstate_eclosure_union): Always return a value.
|
||
|
||
------ version 0.03 ------
|
||
Fri Aug 6 01:57:28 1993 Tom Lord (lord@unix1.andrew.cmu.edu)
|
||
|
||
* rx.c (re_search_2): sped up the fastmap search a little
|
||
to as to not be slower than regex.c on simple patterns.
|
||
Rx will still lose by a couple instructions in some degenerate
|
||
cases but mostly will win.
|
||
|
||
Thu Aug 5 11:39:57 1993 Tom Lord (lord@thisbe.weh.andrew.cmu.edu)
|
||
|
||
* rx.c (re_search_2 & compilation front-ends): cache the starting
|
||
superset of super-nfa's so that it isn't necessary to do an
|
||
eclosure union for every call to re_search_2.
|
||
|
||
* rx.c (re_search_2): (from Eric Backus) arrange to call
|
||
alloca(0) from a shallower stack frame than re_search_2
|
||
if callling it at all.
|
||
|
||
This could use a better cpp test. Right now, an extra function
|
||
call is added to re_search_2 unles __GNUC__ is defined. If
|
||
there were something like _HAVE_LOSER_ALLOCA_....
|
||
|
||
* rx.c (rx_compile, re_search_2, several new fns):
|
||
changed the order of side effect lists so that possible
|
||
futures that begin with complex effects more to the right
|
||
are explored after futures more to the left. Added
|
||
a noop complex effect to alts and stars to guarantee
|
||
they are explored in the right order. An optimization
|
||
after the parse removes some from the alts (and not all
|
||
stars get them in the first place). Changed the `best
|
||
match' criterea -- now that possible futures are ordered
|
||
posixly, we only want to check the length of the match.
|
||
For a given length, the best subexpression partitioning
|
||
is the first one found.
|
||
|
||
A side effect of this is that Rx will always return the
|
||
same register assignements for a given regexp/input text.

||

|
||
ed Jul 21 13:10:56 1993 Tom Lord (lord@unix8.andrew.cmu.edu)
|
||
|
||
* rx.c (re_search_2): elaborated on the rule for picking the
|
||
best match so that the lengths of subexpressions are taken
|
||
into account. This is for Posix compatability.
|
||
|
||
|
||
------ version 0.01 ------
|
||
|
||
Sun Jun 13 17:20:35 1993 Tom Lord (lord@tsunami.ucc.andrew.cmu.edu)
|
||
|
||
* This is the first release of rx.c. Although some of the code
|
||
is derived from regex.c, there is not much continuity between
|
||
the two implementations.
