This patch includes test cases and documentation updates, as well as NEWS file
updates.
This patch also updates the sre modules so that they don't import the string
module, breaking direct circular imports.
A small fix for bug #545855 and Greg Chapman's
addition of op code SRE_OP_MIN_REPEAT_ONE for
eliminating recursion on simple uses of pattern '*?' on a
long string.
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)
-- 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)
-- 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
+ 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
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
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.
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.
-- 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.
(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.
