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 - - * rx.h (rx_search): moved slightly out of date debugging - code from RX_DEBUG to RX_DEBUG_0.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. - ------- version 0.04 ------ - -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. - Bummer :-) / 2. - - ------- version 0.02 ------ - -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. - - - |
