Gustavo Niemeyer 4e7be06a65 Fixed bug #470582, using a modified version of patch #527371,
from Greg Chapman.

* Modules/_sre.c
  (lastmark_restore): New function, implementing algorithm to restore
  a state to a given lastmark. In addition to the similar algorithm used
  in a few places of SRE_MATCH, restore lastindex when restoring lastmark.
  (SRE_MATCH): Replace lastmark inline restoring by lastmark_restore(),
  function. Also include it where missing. In SRE_OP_MARK, set lastindex
  only if i > lastmark.

* Lib/test/re_tests.py
* Lib/test/test_sre.py
  Included regression tests for the fixed bugs.

* Misc/NEWS
  Mention fixes.

Barry Warsaw 408b6d34de Complete the absolute import patch for the test suite. All relative
imports of test modules now import from the test package.  Other
related oddities are also fixed (like DeprecationWarning filters that
weren't specifying the full import part, etc.).  Also did a general
code cleanup to remove all "from test.test_support import *"'s.  Other
from...import *'s weren't changed.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Fredrik Lundh 82b230732f bug #133283, #477728, #483789, #490573
backed out of broken minimal repeat patch from July

also fixed a couple of minor potential resource leaks in pattern_subx
(Guido had already fixed the big one)

Guido van Rossum baefcebb55 Remove erroneous and confusing comment -- sre patterns *can* be
pickled and we do *not* expect exceptions from either pickle or
cPickle.

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...

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.

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.

Fredrik Lundh 1c5aa6901f bumped SRE version number to 2.1. cleaned up and added 1.5.2
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.
2000-09-03 08:15:19 +00:00
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
2000-08-03 16:29:50 +00:00
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

- added test suite
