Thomas Heller 354e3d90d3 Change the zipimport implementation to accept files containing
arbitrary bytes before the actual zip compatible archive.  Zipfiles
containing comments at the end of the file are still not supported.

Add a testcase to test_zipimport, and update NEWS.

This closes sf #775637 and sf #669036.

Jeremy Hylton fb509a36c8 Get socketmodule compiling on IRIX 6.5.10.
I don't think the fix here is very good, but I'm not sure what would
be better.  In particular, we should not be defining _SGIAPI, but lots
of things break if we remove it.

Gregory P. Smith 455d46f0d9 bsddb 4.1.6:
* Extended DB & DBEnv set_get_returns_none functionality to take a
   "level" instead of a boolean flag.  The boolean 0 and 1 values still
   have the same effect.  A value of 2 extends the "return None instead
   of raising an exception" behaviour to the DBCursor set methods.
   This will become the default behaviour in pybsddb 4.2.
 * Fixed a typo in DBCursor.join_item method that made it crash instead
   of returning a value.  Obviously nobody uses it.  Wrote a test case
   for join and join_item.

Martin v. Löwis afec8e3bde Patch #751916: Check for signals, fix some refcounting errors. 2003-06-28 07:40:23 +00:00
Jeremy Hylton 9263f5797c Fix several bugs in handling of exceptions with trace function enabled.
If the callback raised an exception but did not set curexc_traceback,
the trace function was called with PyTrace_RETURN.  That is, the trace
function was called with an exception set.  The main loop detected the
exception when the trace function returned; it complained and disabled
tracing.

Fix the logic error so that PyTrace_RETURN only occurs if the callback
returned normally.

The trace function must be called for exceptions, too.  So we had
to add new functionality to call with PyTrace_EXCEPTION.  (Leads to a
rather ugly ifdef / else block that contains only a '}'.)

Reverse the logic and name of NOFIX_TRACE to FIX_TRACE.

Joint work with Fred.

Raymond Hettinger f69d9f6818 SF bug #761337: datetime.strftime fails on trivial format string
The interning of short strings violates the refcnt==1 assumption for
_PyString_Resize().

A simple fix is to boost the initial value of "totalnew" by 1.
Combined with an NULL argument to PyString_FromStringAndSize(),
this assures that resulting format string is not interned.
This will remain true even if the implementation of
PyString_FromStringAndSize() changes because only the uninitialized
strings that can be interned are those of zero length.

Added a test case.

SF bug [ 751276 ] cPickle doesn't raise error, pickle does (recursiondepth)

Most of the calls to PyErr_Clear() were intended to catch & clear an
attribute error and try something different.  Guard all those cases
with a PyErr_ExceptionMatches() and fail if some other error
occurred.  The other error is likely a bug in the user code.

This is basically the C equivalent of changing "except:" to
"except AttributeError:"

Andrew MacIntyre 1a44448b24 Changes to sre.c after the application of patch #726869 have increased
stack usage on FreeBSD, requiring the recursion limit to be lowered
further.  Building with gcc 2.95 (the standard compiler on FreeBSD 4.x)
is now also affected.

The underlying issue is that FreeBSD's pthreads implementation has a
hard-coded 1MB stack size for the initial (or "primary") thread, which
can not be changed without rebuilding libc_r.  Exhausting this stack
results in a bus error.

Building without pthreads (configure --without-threads), or linking
with the port of the Linux pthreads library (aka Linuxthreads) instead
of libc_r, avoids this limitation.

On OS/2, only gcc 3.2 is affected and the stack size is controllable,
so the special handling has been removed.

Greg Ward d676906ab7 Completely change the interface to setparameters():
* it no longer takes ssize, which served no purpose apart from
    scolding you if you got it wrong
  * changed the order of the three remaining required arguments
    to (format, channels, rate) to match the order in which they
    must be set
  * replaced the optional argument 'emulate' with 'strict': if strict
    true, and the audio device does not accept the requested sampling
    parameters, raise OSSAudioError
  * return a tuple (format, channels, rate) reflecting the sampling
    parameters that were actually set

Change the canonical name of ossaudiodev.error to
ossaudiodev.OSSAudioError (keep an alias for backwards compatibility).

Remove 'audio_types' list and 'n_audio_types' (no longer needed now that
setparameters() no longer has an 'ssize' argument to police).

Tim Peters 3cfe75470d PyType_Ready(): Complain if the type is a base type, and gc'able, and
tp_free is NULL or PyObject_Del at the end.  Because it's a base type
it must call tp_free in its dealloc function, and because it's gc'able
it must not call PyObject_Del.

inherit_slots():  Don't inherit tp_free unless the type and its base
agree about whether they're gc'able.  If the type is gc'able and the
base is not, and the base uses the default PyObject_Del for its
tp_free, give the type PyObject_GC_Del for its tp_free (the appropriate
default for a gc'able type).

cPickle.c:  The Pickler and Unpickler types claim to be base classes
and gc'able, but their dealloc functions didn't call tp_free.
Repaired that.  Also call PyType_Ready() on these typeobjects, so
that the correct (PyObject_GC_Del) default memory-freeing function
gets plugged into these types' tp_free slots.

Tim Peters b0c854d6a7 datetime.timedelta is now subclassable in Python. The new test shows
one good use:  a subclass adding a method to express the duration as
a number of hours (or minutes, or whatever else you want to add).  The
native breakdown into days+seconds+us is often clumsy.  Incidentally
moved a large chunk of object-initialization code closer to the top of
the file, to avoid worse forward-reference trickery.

Gustavo Niemeyer caf1c9dfe7 - Included detailed documentation in _sre.c explaining how, when, and why
to use LASTMARK_SAVE()/LASTMARK_RESTORE(), based on the discussion
  in patch #712900.

- Cleaned up LASTMARK_SAVE()/LASTMARK_RESTORE() usage, based on the
  established rules.

- Moved the upper part of the just commited patch (relative to bug #725106)
  to outside the for() loop of BRANCH OP. There's no need to mark_save()
  in every loop iteration.
2003-04-27 14:42:54 +00:00
Gustavo Niemeyer 3646ab98af Fix for part of the problem mentioned in #725149 by Greg Chapman.
This problem is related to a wrong behavior from mark_save/restore(),
which don't restore the mark_stack_base before restoring the marks.
Greg's suggestion was to change the asserts, which happen to be
the only recursive ops that can continue the loop, but the problem would
happen to any operation with the same behavior. So, rather than
hardcoding this into asserts, I have changed mark_save/restore() to
always restore the stackbase before restoring the marks.

Both solutions should fix these two cases, presented by Greg:

>>> re.match('(a)(?:(?=(b)*)c)*', 'abb').groups()
('b', None)
>>> re.match('(a)((?!(b)*))*', 'abb').groups()
('b', None, None)

The rest of the bug and patch in #725149 must be discussed further.

Gustavo Niemeyer c34f2555bd Applied patch #725106, by Greg Chapman, fixing capturing groups
within repeats of alternatives. The only change to the original
patch was to convert the tests to the new test_re.py file.

This patch fixes cases like:

>>> re.match('((a)|b)*', 'abc').groups()
('b', '')

Which is wrong (it's impossible to match the empty string),
and incompatible with other regex systems, like the following
examples show:

% perl -e '"abc" =~ /^((a)|b)*/; print "$1 $2\n";'
b a

% echo "abc" | sed -r -e "s/^((a)|b)*/\1 \2|/"
b a|c

2003-04-24 10:41:55 +00:00
Raymond Hettinger 88ba1e39ec SF Patch 685051: fix for 680789: reprs in arraymodule
(contributed by logistix; substantially reworked by rhettinger).

To create a representation of non-string arrays, array_repr() was
starting with a base Python string object and repeatedly using +=
to concatenate the representation of individual objects.

Logistix had the idea to convert to an intermediate tuple form and
then join it all at once.  I took advantage of existing tools and
formed a list with array_tolist() and got its representation through
PyObject_Repr(v) which already has a fast implementation for lists.

Tim Peters 11b2306960 Enable os.fsync() for Windows, mapping it to MS's _commit() there. The
docs here are best-guess:  the MS docs I could find weren't clear, and
some even claimed _commit() has no effect on Win32 systems (which is
easily shown to be false just by trying it).

Gustavo Niemeyer be733ee7fb More work on bug #672491 and patch #712900.
I've applied a modified version of Greg Chapman's patch. I've included
the fixes without introducing the reorganization mentioned, for the sake
of stability. Also, the second fix mentioned in the patch don't fix the
mentioned problem anymore, because of the change introduced by patch
#720991 (by Greg as well). The new fix wasn't complicated though, and is
included as well.

As a note. It seems that there are other places that require the
"protection" of LASTMARK_SAVE()/LASTMARK_RESTORE(), and are just waiting
for someone to find how to break them. Particularly, I belive that every
recursion of SRE_MATCH() should be protected by these macros. I won't
do that right now since I'm not completely sure about this, and we don't
have much time for testing until the next release.

Gustavo Niemeyer 1aca359e89 - Fixed bug #672491. This change restores the behavior of lastindex/lastgroup

Tim Peters f6b8045ca5 Reworked has_finalizer() to use the new _PyObject_Lookup() instead
of PyObject_HasAttr(); the former promises never to execute
arbitrary Python code.  Undid many of the changes recently made to
worm around the worst consequences of that PyObject_HasAttr() could
execute arbitrary Python code.

Compatibility is hard to discuss, because the dangerous cases are
so perverse, and much of this appears to rely on implementation
accidents.

To start with, using hasattr() to check for __del__ wasn't only
dangerous, in some cases it was wrong:  if an instance of an old-
style class didn't have "__del__" in its instance dict or in any
base class dict, but a getattr hook said __del__ existed, then
hasattr() said "yes, this object has a __del__".  But
instance_dealloc() ignores the possibility of getattr hooks when
looking for a __del__, so while object.__del__ succeeds, no
__del__ method is called when the object is deleted.  gc was
therefore incorrect in believing that the object had a finalizer.

The new method doesn't suffer that problem (like instance_dealloc(),
_PyObject_Lookup() doesn't believe __del__ exists in that case), but
does suffer a somewhat opposite-- and even more obscure --oddity:
if an instance of an old-style class doesn't have "__del__" in its
instance dict, and a base class does have "__del__" in its dict,
and the first base class with a "__del__" associates it with a
descriptor (an object with a __get__ method), *and* if that
descriptor raises an exception when __get__ is called, then
(a) the current method believes the instance does have a __del__,
but (b) hasattr() does not believe the instance has a __del__.

While these disagree, I believe the new method is "more correct":
because the descriptor *will* be called when the object is
destructed, it can execute arbitrary Python code at the time the
object is destructed, and that's really what gc means by "has a
finalizer":  not specifically a __del__ method, but more generally
the possibility of executing arbitrary Python code at object
destruction time.  Code in a descriptor's __get__() executed at
destruction time can be just as problematic as code in a
__del__() executed then.

So I believe the new method is better on all counts.

Bugfix candidate, but it's unclear to me how all this differs in
the 2.2 branch (e.g., new-style and old-style classes already
took different gc paths in 2.3 before this last round of patches,
but don't in the 2.2 branch).

Tim Peters 259272b7a0 handle_finalizers(): Rewrote to call append_objects() and gc_list_merge()

of the lists' sizes.

append_objects():  Moved up to live with the other list manipulation
utilities.

Tim Peters bf384c256e Reworked move_finalizer_reachable() to create two distinct lists:
externally unreachable objects with finalizers, and externally unreachable
objects without finalizers reachable from such objects.  This allows us
to call has_finalizer() at most once per object, and so limit the pain of
nasty getattr hooks.  This fixes the failing "boom 2" example Jeremy
posted (a non-printing variant of which is now part of test_gc), via never
triggering the nasty part of its __getattr__ method.
2003-04-06 00:11:39 +00:00
Tim Peters f6ae7a43eb move_finalizers(): Rewrote. It's not necessary for this routine
to special-case classic classes, or to worry about refcounts;
has_finalizer() deleted the current object iff the first entry in
the unreachable list has changed.  I don't believe it was correct
to check for ob_refcnt == 1, either:  the dealloc routine would get
called by Py_DECREF then, but there's nothing to stop the dealloc
routine from ressurecting the object, and then gc would remain at
the head of the unreachable list despite that its refcount temporarily
fell to 0 (and that would lead to an infinite loop in move_finalizers()).

I'm still worried about has_finalizer() resurrecting other objects
in the unreachable list:  what's to stop them from getting collected?
2003-04-05 18:40:50 +00:00
Tim Peters 86b993b6cf New comments. Rewrote has_finalizer() as a sequence of ifs instead of
squashed-together conditional operators; makes it much easier to step
thru in the debugger, and to set a breakpoint on the only dangerous
path.
2003-04-05 17:35:54 +00:00
Tim Peters 93ad66dea9 Fixed new seemingly random segfaults, by moving the initialization of
delstr from initgc() into collect().  initgc() isn't called unless the
user explicitly imports gc, so can be used only for initialization of
user-visible module features; delstr needs to be initialized for proper
internal operation, whether or not gc is explicitly imported.

Bugfix candidate?  I don't know whether the new bug was backported to
2.2 already.

pack_float, pack_double, save_float:  All the routines for creating
IEEE-format packed representations of floats and doubles simply ignored
that rounding can (in rare cases) propagate out of a long string of
1 bits.  At worst, the end-off carry can (by mistake) interfere with
the exponent value, and then unpacking yields a result wrong by a factor
of 2.  In less severe cases, it can end up losing more low-order bits
than intended, or fail to catch overflow *caused* by rounding.

Bugfix candidate, but I already backported this to 2.2.

In 2.3, this code remains in severe need of refactoring.

always open mixers with O_RDWR.

Just van Rossum 96b1c903f5 Patch #683592 revisited, after discussions with MvL:
- Implement the behavior as specified in PEP 277, meaning os.listdir()
  will only return unicode strings if it is _called_ with a unicode
  argument.
- And then return only unicode, don't attempt to convert to ASCII.
- Don't switch on Py_FileSystemDefaultEncoding, but simply use the
  default encoding if Py_FileSystemDefaultEncoding is NULL. This means
  os.listdir() can now raise UnicodeDecodeError if the default encoding
  can't represent the directory entry. (This seems better than silcencing
  the error and fall back to a byte string.)
- Attempted to decribe the above in Doc/lib/libos.tex.
- Reworded the Misc/NEWS items to reflect the current situation.

This checkin also fixes bug #696261, which was due to os.listdir() not
using Py_FileSystemDefaultEncoding, like all file system calls are
supposed to.

Michael W. Hudson f008998668 Fix bug
[ 555817 ] Flawed fcntl.ioctl implementation.

with my patch that allows for an array to be mutated when passed
as the buffer argument to ioctl() (details complicated by
backwards compatibility considerations -- read the docs!).
2003-03-03 12:29:42 +00:00
Martin v. Löwis 7f13489bdf Don't crash on _tkinter.createfilehandler in non-threaded Tcl;
disable this function in threaded Tcl. Likewise for creaetetimerhandler.
Fixes #692416.

Neal Norwitz d9efdc5b5a get_completer() takes no args 2003-03-01 15:19:41 +00:00
Raymond Hettinger d1a283be26 Several of the tools can make direct calls the inner iterators. 2003-03-01 01:48:24 +00:00
Neal Norwitz 3f5fcc8acc Fix SF bug #690012 (among others), iconv_codec stops build
Change setup.py to catch all exceptions.
  - Rename module if the exception was an ImportError
  - Only warn if the exception was any other error

Revert _iconv_codec to raising a RuntimeError.
2003-02-28 17:21:39 +00:00
Just van Rossum f4ecc751b1 use proper constant instead of comment (noted by nnorwitz) 2003-02-28 08:54:01 +00:00
Neal Norwitz e9c571f968 Fix SF bug #694816, remove comparison of unsigned value < 0 2003-02-28 03:14:37 +00:00
Just van Rossum 46c9784f68 Patch #683592: unicode support for os.listdir()
os.listdir() may now return unicode strings on platforms that set
Py_FileSystemDefaultEncoding.
2003-02-25 21:42:15 +00:00
Walter Dörwald dd8766a65b Change the test encoding from "ISO8859-1" to "ISO-8859-1"
(see SF bug #690309) and raise ImportErrors instead of
RuntimeErrors, so building Python continues even
if importing iconv_codecs fails.

This is a temporary fix until we get proper configure
support for "broken" iconv implementations.
2003-02-24 20:17:32 +00:00
Neal Norwitz 937ca98e34 SF patch #687598, array.append is sloooow
This improves speed by about 5.6% for me.
2003-02-24 02:08:42 +00:00
Raymond Hettinger 61fe64d5de User requested changes to the itertools module.
Subsumed times() into repeat().
Added cycle() and chain().
2003-02-23 04:40:07 +00:00
Walter Dörwald e9b851a5e9 Use 'ISO8859-1' instead of 'ASCII' when testing whether byteswapping
is required for the chosen internal encoding in the init function,
as this seems to have a better chance of working under Irix and
Solaris.

Also change the test character from '\x01' to '0'.

This might fix SF bug #690309.
2003-02-21 18:18:49 +00:00
Neal Norwitz c355f0cae9 flex_complete looks like a private (but callback) function, so make it static 2003-02-21 00:30:18 +00:00
Guido van Rossum b76bdf8ef7 The connect timeout code wasn't working on Windows.
Rather than trying to second-guess the various error returns
of a second connect(), use select() to determine whether the
socket becomes writable (which means connected).
2003-02-19 17:50:16 +00:00
Guido van Rossum 6297a7a9fb - PyEval_GetFrame() is now declared to return a PyFrameObject *
instead of a plain PyObject *.  (SF patch #686601 by Ben Laurie.)
2003-02-19 15:53:17 +00:00
Mark Hammond 05107b6af7 os.mkdir() would crash with a Unicode filename and mode param. 2003-02-19 04:08:27 +00:00
Guido van Rossum b289b87a37 Use __reduce_ex__. 2003-02-19 01:45:13 +00:00
Tim Peters b9ce7cd8b8 save_global(): Trying to resolve module.name can fail for two
reasons:  importing module can fail, or the attribute lookup
module.name can fail.  We were giving the same error msg for
both cases, making it needlessly hard to guess what went wrong.
These cases give different error msgs now.
2003-02-18 20:50:45 +00:00
Guido van Rossum 55dc26cbc7 Fold some long lines.
Change fatal errors during module initialization into RuntimeErrors.
2003-02-18 16:11:11 +00:00
Neal Norwitz 0c0aad948a Fix 64-bit problem, ParseTuple("i") needs C ints; ("l") needs C longs.
Use "l" as that *probably* makes more sense (at least to me it does :-)
And the test passes on the alpha.
2003-02-18 03:37:49 +00:00
Neal Norwitz e241ce830a Added test_posix (hopefully it works on Windows).
Remove PyArg_ParseTuple() for methods which take no args,
use METH_NOARGS instead
2003-02-17 18:17:05 +00:00
Neal Norwitz 5c1ba53f8c Use correct function name to PyArg_ParseTuple("is_package").
Fix off-by-1 error in normalize_line_endings():
  when *p == '\0' the NUL was copied into q and q was auto-incremented,
  the loop was broken out of,
  then a newline was appended followed by a NUL.
  So the function, in effect, was strcpy() but added two extra chars
  which was caught by obmalloc in debug mode, since there was only
  room for 1 additional newline.

Get test working under regrtest (added test_main).
2003-02-17 18:05:20 +00:00
Neal Norwitz 0ae4c4a823 Make 2 module variables static. Assuming this is correct. 2003-02-15 15:07:17 +00:00
Tim Peters 080c88b912 cPickle.c, load_build(): Taught cPickle how to pick apart
the optional proto 2 slot state.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

pickletester.py, test_pickle.py:  Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

dictobject.c, PyDict_Next():  documented intended use.
2003-02-15 03:01:11 +00:00
Tim Peters 71fcda5ba7 cPickle produces NEWOBJ appropriately now. It still doesn't know
how to unpickle the new slot-full state tuples.
2003-02-14 23:05:28 +00:00
Tim Peters 92c8bb3abf Minor assorted cleanups; no semantic changes. 2003-02-13 23:00:26 +00:00
Tim Peters aae53d47d6 The version of PyImport_Import() in cPickle is no longer needed (an edited
version was moved into import.c long ago), so squashed the duplication.
2003-02-13 22:17:05 +00:00
Tim Peters 5aa3da6495 save(): Reformat tail end just for clarity. 2003-02-13 21:03:57 +00:00
Guido van Rossum 729765079e Another dummy type.
Curious: Str didn't need me to put something in tp_new, but Null did.
Why the difference?
2003-02-13 18:44:57 +00:00
Tim Peters eab7db3cee Taught cPickle how to read pickles containing NEWOBJ. This won't get
exercised by the test suite before cPickle knows how to create NEWOBJ
too.  For now, it was just tried once by hand (via loading a NEWOBJ
pickle created by pickle.py).
2003-02-13 18:24:14 +00:00
Tim Peters 8587b3c073 Added a HIGHEST_PROTOCOL module attribute to pickle and cPickle. 2003-02-13 15:44:41 +00:00
Andrew M. Kuchling fe62bc917d Conditionalize another constant 2003-02-13 13:27:07 +00:00
Tim Peters 1df9fdd4d5 socket_inet_aton(): ip_addr was left undefined before use in the
!HAVE_INET_ATON case.  Repaired that, and tried to repair what looked
like out-of-date comments.
2003-02-13 03:13:40 +00:00
Neal Norwitz 88f115b0d4 Ummm, try to get it right this time 2003-02-13 02:15:42 +00:00
Neal Norwitz 10b214c2fd Use configure to check for inet_aton. 2003-02-13 02:11:10 +00:00
Guido van Rossum ad05cdfa1f Addressing SF bug #643005, implement socket.inet_aton() using
inet_aton() rather than inet_addr() -- the latter is obsolete because
it has a problem: "255.255.255.255" is a valid address but
indistinguishable from an error.

(I'm not sure if inet_aton() exists everywhere -- in case it doesn't,
I've left the old code in with an #ifdef.)
2003-02-12 23:08:22 +00:00
Tim Peters 90975f1ff9 Minor cleanup of new batch-list/dict code. 2003-02-12 05:28:58 +00:00
Neal Norwitz ec74f2fda7 Add more missing PyErr_NoMemory() after failled memory allocs 2003-02-11 23:05:40 +00:00
Tim Peters 42f08ac1e3 Implemented batching for dicts in cPickle. This is after two failed
attempts to merge the C list-batch and dict-batch code -- they worked, but
it was a godawful mess to read.
2003-02-11 22:43:24 +00:00
Guido van Rossum 9eb67ea2af Add Str, a subclass of str. 2003-02-11 21:19:11 +00:00
Tim Peters 1092d64002 Implemented list batching in cPickle. 2003-02-11 21:06:20 +00:00
Gustavo Niemeyer a33d0aa693 Unparenting BZ2File, as discussed in SF patch #661796.
* Modules/bz2module.c
  (BZ2FileObject): Now the structure includes a pointer to a file object,
   instead of "inheriting" one. Also, some members were copied from the
   PyFileObject structure to avoid dealing with the internals of that
   structure from outside fileobject.c.

  (Util_GetLine,Util_DropReadAhead,Util_ReadAhead,Util_ReadAheadGetLineSkip,
   BZ2File_write,BZ2File_writelines,BZ2File_init,BZ2File_dealloc,
   BZ2Comp_dealloc,BZ2Decomp_dealloc):
   	These functions were adapted to the change above.

  (BZ2File_seek,BZ2File_close): Use PyObject_CallMethod instead of
   getting the function attribute locally.

  (BZ2File_notsup): Removed, since it's not necessary anymore to overload
   truncate(), and readinto() with dummy functions.

  (BZ2File_methods): Added xreadlines() as an alias to BZ2File_getiter,
   and removed truncate() and readinto().

  (BZ2File_get_newlines,BZ2File_get_closed,BZ2File_get_mode,BZ2File_get_name,
   BZ2File_getset):
   	Implemented getters for "newlines", "mode", and "name".

  (BZ2File_members): Implemented "softspace" member.

  (BZ2File_init): Reworked to create a file instance instead of initializing
   itself as a file subclass. Also, pass "name" object untouched to the
   file constructor, and use PyObject_CallFunction instead of building the
   argument tuple locally.

  (BZ2File_Type): Set tp_new to PyType_GenericNew, tp_members to
   BZ2File_members, and tp_getset to BZ2File_getset.

  (initbz2): Do not set BZ2File_Type.tp_base nor BZ2File_Type.tp_new.


* Doc/lib/libbz2.tex
  Do not mention that BZ2File inherits from the file type.

Tim Peters 5f322d3dfd SF bug 684667: Modules/selectmodule.c returns NULL without exception set.
select_select() didn't set an exception in the SELECT_USES_HEAP case when
malloc() returned NULL.

Raymond Hettinger 60eca9331a C Code:
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.

Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().

Sets.py:
* Replace old ifilter() usage with new.

2003-02-08 18:05:10 +00:00
Tim Peters aa7d849c7a timedelta comparison and datetime addition: as the Python implementation
of datetime does, accept instances of subclasses too.
2003-02-08 03:28:59 +00:00
Tim Peters 07534a607b Comparison for timedelta, time, date and datetime objects: __eq__ and
__ne__ no longer complain if they don't know how to compare to the other
thing.  If no meaningful way to compare is known, saying "not equal" is
sensible.  This allows things like

    if adatetime in some_sequence:
and
    somedict[adatetime] = whatever

to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.

It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().

Neal Norwitz 4d933fe392 SF patch #682514, mmapmodule.c write fix for LP64 executables

Will backport.
2003-02-07 19:44:56 +00:00
Raymond Hettinger f0c00241ae * Eliminated tuple re-use in imap(). Doing it correctly made the code
too hard to read.
* Simplified previous changes to izip() to make it easier to read.
2003-02-07 07:26:25 +00:00
Raymond Hettinger 2012f174ea SF bug #681003: itertools issues
* Fixed typo in exception message for times()
* Filled in missing times_traverse()
* Document reasons that imap() did not adopt a None fill-in feature
* Document that count(sys.maxint) will wrap-around on overflow
* Add overflow test to islice()
* Check that starmap()'s argument returns a tuple
* Verify that imap()'s tuple re-use is safe
* Make a similar tuple re-use (with safety check) for izip()

Tim Peters 3e667d5452 cPickle: exempt two_tuple from GC -- it's a speed hack, and doesn't
guarantee to keep valid pointers in its slots.

tests:  Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places.  Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.

Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.
2003-02-04 21:47:44 +00:00
Tim Peters 731098b3ff cPickle now generates proto 2 EXT[124] when appropriate.
Moved such EXT tests as currently exist from TempAbstractPickleTests to
AbstractPickleTests, so that test_cpickle runs them too.

generate these opcodes.
2003-02-04 05:06:17 +00:00
Guido van Rossum d4b920c8bd Rename the extension registry variables to have leading underscores --
this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.

Tim Peters 0c7c48e02c load_counted_long(): Changed a ValueError to an UnpicklingError, just
because it seems more consistent with the rest of the code.

cPickle_PyMapping_HasKey():  This extern function isn't used anywhere in
Python or Zope, so got rid of it.
2003-02-03 22:07:24 +00:00
Guido van Rossum 7d9ea5013f - Thanks to Scott David Daniels, a subtle bug in how the zlib
extension implemented flush() was fixed.  Scott also rewrite the

  patch #678531.)

Backport candidate I think.
