* Comparison for timedelta, time, date and datetime objects: __eq__ andTim Peters2003-02-071-38/+52
| | | | | | | | | | | | | | | | | __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().
* SF patch #682514, mmapmodule.c write fix for LP64 executablesNeal Norwitz2003-02-071-1/+1
| | | | | | | Make length an int so we get the right value from PyArg_ParseTuple(args, "s#", &str, &length) Will backport.
* * Eliminated tuple re-use in imap(). Doing it correctly made the codeRaymond Hettinger2003-02-071-62/+30
| | | | | too hard to read. * Simplified previous changes to izip() to make it easier to read.
* SF bug #681003: itertools issuesRaymond Hettinger2003-02-071-6/+84
| | | | | | | | | | | * 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()

| | | | | | | | | | | | 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.
* cPickle now generates proto 2 EXT[124] when appropriate.Tim Peters2003-02-041-2/+67
| | | | | Moved such EXT tests as currently exist from TempAbstractPickleTests to AbstractPickleTests, so that test_cpickle runs them too.

* Rename the extension registry variables to have leading underscores --Guido van Rossum2003-02-041-6/+6
| | | | | | | | | 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.

* Brought some module variables into synch with pickle.py's current values.Tim Peters2003-02-041-16/+47
| | | | | Imported the extension-registry dicts from copy_reg.py, in preparation for tackling EXT[124].
* load_counted_long(): Changed a ValueError to an UnpicklingError, justTim Peters2003-02-031-15/+1
| | | | | | | 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.
* - Thanks to Scott David Daniels, a subtle bug in how the zlibGuido van Rossum2003-02-031-12/+45
| | | | | | | | extension implemented flush() was fixed. Scott also rewrite the zlib test suite using the unittest module. (SF bug #640230 and patch #678531.) Backport candidate I think.
* PDATA_PUSH and PDATA_APPEND. documented, and reformatted for betterTim Peters2003-02-031-30/+38
| | | | | | | | | readability. load_bool(): Now that I know the intended difference between _PUSH and _APPEND, used the right one. Pdata_grow(): Squashed out a redundant overflow test.

| | | | | | | | | | | | | | a function, then p->f(arg1, arg2, ...) is semantically the same as (*p->f)(arg1, arg2, ...) Changed all instances of the latter into the former. Given how often the code embeds this kind of expression in an if test, the unnecessary parens and dereferening operator were a real drag on readability.

| | | | | | | loops. Renamed DATA and BINDATA to DATA0 and DATA1. Included disassemblies, but noted why we can't test them. Added XXX comment to cPickle about a mysterious comment, where pickle and cPickle diverge in how they number PUT indices.

* dump(): Fixed a stupid bug in new code. It wasn't possible for the bugTim Peters2003-02-021-1/+1
| | | | | to have an effect before protocol 3 is invented, so no test can be written for this (yet).

* cPickle.c: Full support for the new LONG1 and LONG4. Added comments.Tim Peters2003-02-021-21/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's no need to do things like multiply by sizeof(char) in hairy malloc arguments. Fixed an undetected-overflow bug in readline_file(). longobject.c: Fixed a really stupid bug in the new _PyLong_NumBits. pickle.py: Fixed stupid bug in save_long(): When proto is 2, it wrote LONG1 or LONG4, but forgot to return then -- it went on to append the proto 1 LONG opcode too. Fixed equally stupid cancelling bugs in load_long1() and load_long4(): they *returned* the unpickled long instead of pushing it on the stack. The return values were ignored. Tests passed before only because save_long() pickled the long twice. Fixed bugs in encode_long(). Noted that decode_long() is quadratic-time despite our hopes, because long(string, 16) is still quadratic-time in len(string). It's hex() that's linear-time. I don't know a way to make decode_long() linear-time in Python, short of maybe transforming the 256's-complement bytes into marshal's funky internal format, and letting marshal decode that. It would be more valuable to make long(string, 16) linear time. pickletester.py: Added a global "protocols" vector so tests can try all the protocols in a sane way. Changed test_ints() and test_unicode() to do so. Added a new test_long(), but the tail end of it is disabled because it "takes forever" under pickle.py (but runs very quickly under cPickle: cPickle proto 2 for longs is linear-time).

| | | | | removed woefully inadequate opcode docs and pointed to pickletools.py instead.
* New functions alloc_{time,datetime}. Got rid of all setstate-likeTim Peters2003-02-011-168/+123
| | | | | | | | | | functions. Reworked {time,datetime}_new() to do what their corresponding setstates used to do in their state-tuple-input paths, but directly, without constructing an object with throwaway state first. Tightened the "is this a state tuple input?" paths to check the presumed state string-length too, and to raise an exception if the optional second state element isn't a tzinfo instance (IOW, check these paths for type errors as carefully as the normal paths).
* There's no good reason for datetime objects to expose __getstate__()Tim Peters2003-02-011-52/+4
| | | | | | anymore either, so don't. This also allows to get rid of obscure code making __getnewargs__ identical to __getstate__ (hmm ... hope there wasn't more to this than I realize!).

* The various datetime object __setstate__() methods are no longer publicTim Peters2003-01-311-116/+105
| | | | | | | | (pickling no longer needs them, and immutable objects shouldn't have visible __setstate__() methods regardless). Rearranged the code to put the internal setstate functions in the constructor sections. Repaired the timedelta reduce() method, which was still producing stuff that required a public timedelta.__setstate__() when unpickling.
* Ignore the state returned by __reduce__ if it is Py_None.Guido van Rossum2003-01-311-0/+2

* SF patch #678257 by Geoff Talvola.Guido van Rossum2003-01-311-1/+1

* SF patch 676472 by Geoff Talvola, reviewed by Ben Laurie.Guido van Rossum2003-01-311-13/+65
| | | | | | | | | | | | Geoff writes: This is yet another patch to _ssl.c that sets the underlying BIO to non-blocking if the socket being wrapped is non-blocking. It also correctly loops when SSL_connect, SSL_write, or SSL_read indicates that it needs to read or write more bytes. This seems to fix bug #673797 which was not fixed by my previous patch.
* Change the treatment of positions returned by PEP293Walter Dörwald2003-01-311-4/+14
| | | | | | | | | | | | | | | | error handers in the Unicode codecs: Negative positions are treated as being relative to the end of the input and out of bounds positions result in an IndexError. Also update the PEP and include an explanation of this in the documentation for codecs.register_error. Fixes a small bug in iconv_codecs: if the position from the callback is negative *add* it to the size instead of substracting it. From SF patch #677429.
