    Many calls to tk.call involve an arglist containing a single tuple.
    Calls using METH_OLDARGS unpack this tuple; calls using METH_VARARG
    don't.  Tcl's concatenation of args was affected; IDLE doesn't start.

    Modify Tkapp_Call() to unpack single tuple arglists.

  Dict comprehensions. Still needs doc changes (like many python-3000 features
  ;-). It generates bytecode similar to:

  x = {}
  for k, v in (generator here):
    x[k] = v

  except there is no tuple-packing and -unpacking involved. Trivial
  measurement suggests it's significantly faster than dict(generator here) (in
  the order of 2 to 3 times as fast) but I have not done extensive
  measurements.

Guido van Rossum 6b826abc70 Creating an array with a bytes object as initializer
should treat the bytes as it treats a string.
Not doing this broke re.compile() of big charsets.

  So long xrange.  range() now supports values that are outside
  -sys.maxint to sys.maxint.  floats raise a TypeError.

  This has been sitting for a long time.  It probably has some problems and

  it is almost completely new.

Guido van Rossum 572dbf8f13 Checkpoint. Manipulated things so that string literals are always
unicode, and a few other compensating changes, e.g. str <- unicode,
chr <- unichr, and repr() of a unicode string no longer starts
with 'u'.  Lots of unit tests are broken, but some basic things
work, in particular distutils works so the extensions can be built,
and test_builtin.py works.

Raymond Hettinger 01c9f8c35f Simple optimizations:
* pre-build a single identity function for the fixup function
* pre-build membership tests in dictionaries instead of in-line tuples
* assign len() to a local variable
* assign append() methods to a local variable
* use xrange() instead of range()
* replace "x<<1" with "x+x"

Guido van Rossum 577fb5a1db Fix from SF patch #633359 by Greg Chapman for SF bug #610299:
The problem is in sre_compile.py: the call to
    _compile_charset near the end of _compile_info forgets to
    pass in the flags, so that the info charset is not compiled
    with re.U. (The info charset is used when searching to find
    the first character at which a match could start; it is not
    generated for patterns beginning with a repeat like '\w{1}'.)
2003-02-24 01:18:35 +00:00
Martin v. Löwis 67c4cb1f13 Disable big charsets in UCS-4 builds. Works around #599377.

2001-02-18 12:05:16 +00:00
Skip Montanaro 0de65807e6 bunch more __all__ lists
also modified check_all function to suppress all warnings since they aren't
relevant to what this test is doing (allows quiet checking of regsub, for
instance)
2001-02-15 22:15:14 +00:00
Fredrik Lundh 2e24044f9d from the really-stupid-bug department: uppercase literals should match
uppercase strings also when the IGNORECASE flag is set (bug #128899)

(also added test cases for recently fixed bugs to the regression suite
-- or in other words, check in re_tests.py too...)
2001-01-15 18:28:14 +00:00
Fredrik Lundh b35ffc0417 added "magic" number to the _sre module, to avoid weird errors caused

2001-01-15 12:46:09 +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
Fredrik Lundh 13ac9926ac Fixed too ambitious "nothing to repeat" check. Closes bug #114033. 2000-10-07 17:38:23 +00:00
Fredrik Lundh 7898c3e685 -- reset marks if repeat_one tail doesn't match
(this should fix Sjoerd's xmllib problem)
-- added skip field to INFO header
-- changed compiler to generate charset INFO header
-- changed trace messages to support post-mortem analysis
2000-08-07 20:59:04 +00:00
Fredrik Lundh e186983842 final 0.9.8 updates:
-- added REPEAT_ONE operator
-- added ANY_ALL operator (used to represent "(?s).")
2000-08-01 22:47:49 +00:00
Fredrik Lundh 2f2c67d7e5 -- fixed width calculations for alternations
-- fixed literal check in branch operator
   (this broke test_tokenize, as reported by Mark Favas)
-- added REPEAT_ONE operator (still not enabled, though)
-- added some debugging stuff (maxlevel)
2000-08-01 21:05:41 +00:00
Fredrik Lundh 29c4ba9ada SRE 0.9.8: passes the entire test suite
-- reverted REPEAT operator to use "repeat context" strategy
   (from 0.8.X), but done right this time.
-- got rid of backtracking stack; use nested SRE_MATCH calls
   instead (should probably put it back again in 0.9.9 ;-)
-- properly reset state in scanner mode
-- don't use aggressive inlining by default
2000-08-01 18:20:07 +00:00
Fredrik Lundh 8a3ebf8ca8 -- SRE 0.9.6 sync. this includes:
+ added "regs" attribute
 + fixed "pos" and "endpos" attributes
 + reset "lastindex" and "lastgroup" in scanner methods
 + removed (?P#id) syntax; the "lastindex" and "lastgroup"
   attributes are now always set
 + removed string module dependencies in sre_parse
 + better debugging support in sre_parse
 + various tweaks to build under 1.5.2
2000-07-23 21:46:17 +00:00
Fredrik Lundh 2855290b84 maintenance release:
- reorganized some code to get rid of -Wall and -W4
  warnings

- fixed default argument handling for sub/subn/split
  methods (reported by Peter Schneider-Kamp).
2000-07-05 21:14:16 +00:00
Fredrik Lundh 72b82ba16d - fixed grouping error bug
- changed "group" operator to "groupref"
2000-07-03 21:31:48 +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...
2000-07-03 18:44:21 +00:00
Fredrik Lundh c2301730b8 - experimental: added two new attributes to the match object:
"lastgroup" is the name of the last matched capturing group,
  "lastindex" is the index of the same group.  if no group was
  matched, both attributes are set to None.

  the (?P#) feature will be removed in the next relase.
2000-07-02 22:25:39 +00:00
Fredrik Lundh 7cafe4d7e4 - actually enabled charset anchors in the engine (still not
used by the code generator)

- changed max repeat value in engine (to match earlier array fix)

- added experimental "which part matched?" mechanism to sre; see
  http://hem.passagen.se/eff/2000_07_01_bot-archive.htm#416954
  or python-dev for details.
2000-07-02 17:33:27 +00:00
Fredrik Lundh 3562f11764 -- use charset bitmaps where appropriate. this gives a 5-10%
speedup for some tests, including the python tokenizer.

-- added support for an optional charset anchor to the engine
   (currently unused by the code generator).

-- removed workaround for array module bug.
2000-07-02 12:00:07 +00:00
Fredrik Lundh 22d2546520 today's SRE update:
-- changed 1.6 to 2.0 in the file headers

-- fixed ISALNUM macro for the unicode locale.  this
   solution isn't perfect, but the best I can do with
   Python's current unicode database.
2000-07-01 17:50:59 +00:00
Fredrik Lundh 55a4f4a528 - fixed code generation error in multiline mode
- fixed parser flag propagation (of all stupid bugs...)
2000-06-30 22:37:31 +00:00
Fredrik Lundh 4ccea94152 - reverted to "\x is binary byte"
- removed evil tabs from sre_parse and sre_compile
2000-06-30 18:39:20 +00:00
Fredrik Lundh 0640e1161f the mad patcher strikes again:
-- added pickling support (only works if sre is imported)

-- fixed wordsize problems in engine
   (instead of casting literals down to the character size,
   cast characters up to the literal size (same as the code
   word size).  this prevents false hits when you're matching
   a unicode pattern against an 8-bit string. (unfortunately,
   this broke another test, but I think the test should be
   changed in this case; more on that on python-dev)

-- added sre.purge function
   (unofficial, clears the cache)
2000-06-30 13:55:15 +00:00
Fredrik Lundh 43b3b49b5a - fixed lookahead assertions (#10, #11, #12)
- untabified sre_constants.py
2000-06-30 10:41:31 +00:00
Fredrik Lundh 90a0791322 - pedantic: make sure "python -t" doesn't complain... 2000-06-30 07:50:59 +00:00
Fredrik Lundh 01016fe972 - fixed split behaviour on empty matches
- fixed compiler problems when using locale/unicode flags

- fixed group/octal code parsing in sub/subn templates
2000-06-30 00:27:46 +00:00
Fredrik Lundh 29c08beab0 still trying to figure out how to fix the remaining
group reset problem.  in the meantime, I added some
optimizations:

- added "inline" directive to LOCAL

  (this assumes that AC_C_INLINE does what it's
  supposed to do).  to compile SRE on a non-unix
  platform that doesn't support inline, you have
  to add a "#define inline" somewhere...

- added code to generate a SRE_OP_INFO primitive

- added code to do fast prefix search

  (enabled by the USE_FAST_SEARCH define; default
  is on, in this release)
2000-06-29 23:33:12 +00:00
Fredrik Lundh 8094611eb8 - fixed another split problem
(those semantics are weird...)

- got rid of $Id$'s (for the moment, at least).  in other
  words, there should be no more "empty" checkins.

- internal: some minor cleanups.
2000-06-29 18:03:25 +00:00
Fredrik Lundh be2211e940 - fixed split
(test_sre still complains about split, but that's caused by
  the group reset bug, not split itself)

- added more mark slots
  (should be dynamically allocated, but 100 is better than 32.
  and checking for the upper limit is better than overwriting
  the memory ;-)

- internal: renamed the cursor helper class

- internal: removed some bloat from sre_compile
2000-06-29 16:57:40 +00:00
Fredrik Lundh 6c68dc7b1a - removed "alpha only" licensing restriction
- removed some hacks that worked around 1.6 alpha bugs
- removed bogus test code from sre_parse

Jeremy Hylton b1aa19515f Fredrik Lundh: here's the 96.6% version of SRE 2000-06-01 17:39:12 +00:00
Guido van Rossum b81e70ebdb Fredrik Lundh: new snapshot. Mostly reindented.
This one should work with unicode expressions, and compile
a bit more silently.
2000-04-10 17:10:48 +00:00
Andrew M. Kuchling e3ba931aa4 This patch looks large, but it just deletes the ^M characters and
untabifies the files.  No actual code changes were made.
2000-04-02 05:22:30 +00:00
Guido van Rossum 7627c0de69 Added Fredrik Lundh's sre module and its supporting cast.
NOTE: THIS IS VERY ROUGH ALPHA CODE!
