* Fix a couple of crashing-on-malformed data marshal bugs.Michael W. Hudson2005-06-031-6/+8
|
* This is my patch:Michael W. Hudson2005-06-032-66/+177
| | | | | | | | | [ 1180995 ] binary formats for marshalling floats Adds 2 new type codes for marshal (binary floats and binary complexes), a new marshal version (2), updates MAGIC and fiddles the de-serializing of code objects to be less likely to clobber the real reason for failing if it fails.
* This is my patch:Michael W. Hudson2005-05-271-0/+2
| | | | | | | | | | | | | | [ 1181301 ] make float packing copy bytes when they can which hasn't been reviewed, despite numerous threats to check it in anyway if noone reviews it. Please read the diff on the checkin list, at least! The basic idea is to examine the bytes of some 'probe values' to see if the current platform is a IEEE 754-ish platform, and if so _PyFloat_{Pack,Unpack}{4,8} just copy bytes around. The rest is hair for testing, and tests.
* Patch #1197318: Cygwin case-sensitive import patchJason Tishler2005-05-201-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | A problem regarding importing symlinked modules was recently reported on the Cygwin mailing list: http://cygwin.com/ml/cygwin/2005-04/msg00257.html The following test case demonstrates the problem: $ ls -l total 1 lrwxrwxrwx 1 jt None 6 Apr 23 13:32 bar.py -> foo.py -rw-r--r-- 1 jt None 24 Apr 18 20:13 foo.py $ python -c 'import bar' Traceback (most recent call last): File "<string>", line 1, in ? ImportError: No module named bar Since Cygwin's case_ok() uses a modified version of the Windows's version, the symlinked bar module actually resolves to file foo.py instead of bar.py. This obviously causes the matching code to fail (regardless of case). The patch fixes this problem by making Cygwin use the Mac OS X case_ok() instead of a modified Window's version.

| | | | | | Add a test in case the underlying assumptions ever change (i.e. the compiler starts generating code blocks that are not punctuated by RETURN_VALUE).

* Transform "x in (1,2,3)" to "x in frozenset([1,2,3])".Raymond Hettinger2005-02-061-1/+48
| | | | | Inspired by Skip's idea to recognize the throw-away nature of sequences in this context and to transform their type to one with better performance.
* Fix bug that allowed future statements virtually anywhere in a module.Jeremy Hylton2005-02-041-2/+1
| | | | | | | If we exit via the break here, we need to set ff_last_lineno or FUTURE_POSSIBLE() will remain true. The bug affected statements containing a variety of expressions, but not all expressions. It has been present since Python 2.2.

* SF bug 1061968: threads: segfault or Py_FatalError at exitTim Peters2004-11-081-13/+12
| | | | | | | | | | | | | | | | | PyGILState_Ensure(): The fix in 2.4a3 for bug 1010677 reintroduced thread shutdown race bug 225673. Repaired by (once again) ensuring the GIL is held whenever deleting a thread state. Alas, there's no useful test case for this shy bug. Four years ago, only Guido could provoke it, on his box, and today only Armin can provoke it on his box. I've never been able to provoke it (but not for lack of trying!). This is a critical fix for 2.3.5 too, since the fix for 1010677 got backported there already and so also reintroduced 225673. I don't intend to backport this fix. For whoever (if anyone) does, there are other thread fixes in 2.4 that need backporting too, and I bet they need to happen first for this patch to apply cleanly.
* SF patch 1025636: Check for NULL returns in compile.c:com_import_stmtJeremy Hylton2004-11-071-4/+14
| | | | There is no test for this change, because there is no way to provoke memory errors on demand. Test suite passes, though.
* SF patch #1035255: Remove CoreServices / CoreFoundation dependencies in coreRaymond Hettinger2004-11-051-158/+67
| | | | | | | | | | | | | (Contributed by Bob Ippolito.) This patch trims down the Python core on Darwin by making it independent of CoreFoundation and CoreServices. It does this by: Changed linker flags in configure/configure.in Removed the unused PyMac_GetAppletScriptFile Moved the implementation of PyMac_StrError to the MacOS module Moved the implementation of PyMac_GetFullPathname to the Carbon.File module
* Maintain peepholer's cumlc invariant by updating the running totalRaymond Hettinger2004-11-021-0/+4
| | | | | | everytime a LOAD_CONSTANT is encountered, created, or overwritten. Added two tests to cover cases affected by the patch.
* Simplify and future proof NOP counting in the peepholer.Raymond Hettinger2004-11-011-13/+6

* Adopt some peepholer suggestions from Armin Rigo:Raymond Hettinger2004-10-301-15/+20
| | | | | | | | * Use simpler, faster two pass algorithm for markblocks(). * Free the blocks variable if not NULL and exiting without change. * Verify that the rest of the compiler has not set an exception. * Make the test for tuple of constants less restrictive. * Embellish the comment for chained conditional jumps.
* SF bug #1053819: Segfault in tuple_of_constantsRaymond Hettinger2004-10-261-1/+9
| | | | | | | Peepholer could be fooled into misidentifying a tuple_of_constants. Added code to count consecutive occurrences of LOAD_CONST. Use the count to weed out the misidentified cases. Added a unittest.
