Fredrik Lundh 59b68656f8 fixed #449964: sre.sub raises an exception if the template contains a
\g<x> group reference followed by a character escape

(also restructured a few things on the way to fixing #449000)

Fredrik Lundh 21009b9c6f an SRE bugfix a day keeps Guido away...
#462270: sub-tle difference between pre.sub and sre.sub.  PRE ignored
an empty match at the previous location, SRE didn't.

also synced with Secret Labs "sreopen" codebase.

Guido van Rossum e056e4d15c Check in a testcase for SF bug #449000: re.sub(r'\n', ...) broke. 2001-08-10 14:52:48 +00:00
Fredrik Lundh df781e6a3f reapplied darryl gallion's minimizing repeat fix. I'm still not 100%
sure about this one, but test #133283 now works even with the fix in
place, and so does the test suite.  we'll see what comes up...

Fredrik Lundh 015415ed14 SRE 2.1b2: increase the chances that the sre test works on other
machines...
2001-03-22 23:48:28 +00:00
Fredrik Lundh b25e1ad253 sre 2.1b2 update:
- take locale into account for word boundary anchors (#410271)
- restored 2.0's *? behaviour (#233283, #408936 and others)
- speed up re.sub/re.subn

Fredrik Lundh f2989b22ff - restored 1.5.2 compatibility (sorry, eric)
- removed __all__ cruft from internal modules (sorry, skip)
- don't assume ASCII for string escapes (sorry, per)

Eric S. Raymond 2846b0ab41 String method conversion.
(This one was trivial -- no actual string. references in it!)

Fredrik Lundh f785042433 a bold attempt to fix things broken by MAL's verify patch: import
'verify' iff it's used by a test module...

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

compatibility patches.

Fredrik Lundh fa25a7d51f -- don't use recursion for unbounded non-greedy repeat
(bugs #115903, #115696)

This is based on a patch by Darrel Gallion.  I'm not 100%
sure about this fix, but I haven't managed to come up with
any test case it cannot handle...

Fredrik Lundh 538f05c94d reapplied Fred's "recommended style" patch... 2001-01-14 15:15:37 +00:00
Fredrik Lundh 770617b23e SRE fixes for 2.1 alpha:
-- added some more docstrings
-- fixed typo in scanner class (#125531)
-- the multiline flag (?m) should't affect the \Z operator (#127259)
-- fixed non-greedy backtracking bug (#123769, #127259)
-- added sre.DEBUG flag (currently dumps the parsed pattern structure)
-- fixed a couple of glitches in groupdict (the #126587 memory leak
   had already been fixed by AMK)
2001-01-14 15:06:11 +00:00
Fred Drake 132dce2246 Update the code to better reflect recommended style:
Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.
2000-12-12 23:11:42 +00:00
Fredrik Lundh ebc37b28fa -- properly reset groups in findall (bug #117612)
-- fixed negative lookbehind to work correctly at the beginning
of the target string (bug #117242)

-- improved syntax check; you can no longer refer to a group
inside itself (bug #110866)
2000-10-28 19:30:41 +00:00
Fredrik Lundh 19f977ba40 - don't hang if group id is followed by whitespace (closes bug #114660) 2000-09-24 14:46:23 +00:00
Fredrik Lundh 03dd010b4f updated SRE test suite (fixes PEP223 problem, shows syntax errors) 2000-09-03 10:43:16 +00:00
Tim Peters acee48628d Repair failing test_sre.py.
This was a funny one!  The test very subtly relied on 1.5.2's
behavior of treating "\x%" as "\x%", i.e. ignoring that was an
\x escape that didn't make sense.  But /F implemented PEP 223,
which causes 2.0 to raise an exception on the bad escape.
Fixed by merely making the 3 such strings of this kind into
raw strings.

Fredrik Lundh 510c97ba2f return -1 for undefined groups (as implemented in 1.5.2) instead of
None (as documented) from start/end/span.  closes bug #113254
2000-09-02 16:36:57 +00:00
Fredrik Lundh 143328ba63 -- tightened up parsing of octal numbers
-- improved the SRE test harness: don't use asserts, test a few more
   things (including more boundary conditions)
2000-09-02 11:03:34 +00:00
Fredrik Lundh 5810064476 -- changed findall to return empty strings instead of None
for undefined groups
2000-08-09 09:14:35 +00:00
Fredrik Lundh 96ab46529b -- added recursion limit (currently ~10,000 levels)
-- improved error messages
-- factored out SRE_COUNT; the same code is used by
   SRE_OP_REPEAT_ONE_TEMPLATE
-- minor cleanups

Fredrik Lundh 067bebfe2d -- SRE 0.9.8: now that the bug is fixed, I might as well enable
the test again...

Fredrik Lundh c2ed621d75 -- SRE 0.9.8: updated test scripts 2000-08-01 13:01:43 +00:00
Fredrik Lundh 6f01398236 - added lookbehind support (?<=pattern), (?<!pattern).
the pattern must have a fixed width.

- got rid of array-module dependencies; the match pro-
  gram is now stored inside the pattern object, rather
  than in an extra string buffer.

- cleaned up a various of potential leaks, api abuses,
  and other minors in the engine module.

- use mal's new isalnum macro, rather than my own work-
  around.

- untabified test_sre.py.  seems like I removed a couple
  of trailing spaces in the process...

Fredrik Lundh 90a0791322 - pedantic: make sure "python -t" doesn't complain... 2000-06-30 07:50:59 +00:00
Fredrik Lundh df02d0b3f0 - fixed default value handling in group/groupdict
- added test suite
