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.
