errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"
(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))
As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.
These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.
get_starttag_text(): New method.
Return the text of the most recently parsed start tag, from
the '<' to the '>' or '/'. Not really useful for structure
processing, but requested for Web-related use. May also be
useful for being able to re-generate the input from the parse
events, but there's no equivalent for end tags.
attrfind: Be a little more forgiving of unquoted attribute values.
(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.
(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
threads use --without-threads. No extra tests of thread/compiler
combinations have been added.
--with(out)-thread and --with(out)-threads are completely
interchangeable.
--with-threads still supports the =DIRECTORY option for specifying
where to find thread libraries.
accidentally wiped out by Ping's patch (which shouldn't have affected
this file at all, had Ping done a cvs update).
This checkin restores Gordon's version, with Fredrik's change merged
back in.
tests in sre_patch back to previous version
- fixed return value from findall
- renamed a bunch of functions inside _sre (way too
many leading underscores...)
</F>
Changed 'prune_file_list()' so it also prunes out RCS and CVS directories.
Added 'is_regex' parameter to 'select_pattern()', 'exclude_pattern()',
and 'translate_pattern()', so that you don't have to be constrained
by the simple shell-glob-like pattern language, and can escape into
full-blown regexes when needed. Currently this is only available
in code -- it's not exposed in the manifest template mini-language.
Added 'prune' option (controlled by --prune and --no-prune) to determine
whether we call 'prune_file_list()' or not -- it's true by default.
Fixed 'negative_opt' -- it was misnamed and not being seen by dist.py.
Added --no-defaults to the option table, so it's seen by FancyGetopt.
This patch fixes a problem on AIX with the signed int case code in
getargs.c, after Trent Mick's intervention about MIN/MAX overflow
checks. The AIX compiler/optimizer generates bogus code with the
default flags "-g -O" causing test_builtin to fail: int("10", 16) <>
16L. Swapping the two checks in the signed int code makes the problem
go away.
Also, make the error messages fit in 80 char lines in the
source.
Avoid calling the dealloc function, previously triggered with
DECREF(inst). This caused a segfault in PyDict_GetItem, called with a
NULL dict, whenever inst->in_dict fails under low-memory conditions.
The depth field was never decremented inside w_object(), and it was
never initialized in PyMarshal_WriteObjectToFile().
This caused imports from .pyc files to fil mysteriously when the .pyc
file was written by the broken code -- w_object() would bail out
early, but PyMarshal_WriteObjectToFile() doesn't check the error or
return an error code, and apparently the marshalling code doesn't call
PyErr_Check() either. (That's a separate patch if I feel like it.)
mislabeled.
(Using -c and then -e rearranges some comments, so I won't check that
in -- but it's a good test anyway.
Note that pindent is not perfect -- e.g. it doesn't know about
triple-quoted strings!)
Problem:
A Python program can be completed and reformatted using
Tools/scripts/pindent.py. Unfortunately there is no option for removal
of the generated "# end"-tags. Although a few Python commands or a
"grep -v '# end '" can do wonders here, there are two drawbacks:
- not everyone has grep/time to write a Python script
- it is not checked whether the "# end"-tags were used validly
Solution:
add extra option "-e" (eliminate) to pindent.py
Fix warnings on 64-bit build build of signalmodule.c
- Though I know that SIG_DFL and SIG_IGN are just small constants,
there are cast to function pointers so the appropriate Python call is
PyLong_FromVoidPtr so that the pointer value cannot overflow on Win64
where sizeof(long) < sizeof(void*).
This patch fixes cPickle.c for 64-bit platforms.
- The false assumption sizeof(long) == size(void*) exists where
PyInt_FromLong is used to represent a pointer. The safe Python call
for this is PyLong_FromVoidPtr. (On platforms where the above
assumption *is* true a PyInt is returned as before so there is no
effective change.)
- use size_t instead of int for some variables
