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 + + * rx.h (rx_search): moved slightly out of date debugging + code from RX_DEBUG to RX_DEBUG_0.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.

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. + + + |
