* Move itertools module from the sandbox and into production.Raymond Hettinger2003-02-018-0/+2027

* The various datetime object __setstate__() methods are no longer publicTim Peters2003-01-312-117/+111
| | | | | | | | (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.
* Changed the tests to stop using __setstate__(). __setstate__() noTim Peters2003-01-311-65/+31
| | | | | | longer needs to be public, and shoudn't be public because all datetime objects are immutable. The Python implementation has changed accordingly, but still need to change the C implementation.

* Pass the preprocessor options also to the resource compilerThomas Heller2003-01-311-1/+1

* Add extension management to __all__.Guido van Rossum2003-01-311-1/+2
|
* Change the default protocol back to 0.Guido van Rossum2003-01-311-8/+12
| | | | | Add a feature suggested by Tim: a negative protocol value means to use the largest protocol value supported.
* Another extension to reduce(). It can return a 4- or 5-tuple now.Guido van Rossum2003-01-311-67/+92
| | | | | | | | | | | | | | The 4th item can be None or an iterator yielding list items, which are used to append() or extend() the object. The 5th item can be None or an iterator yielding a dict's (key, value) pairs, which are stuffed into the object using __setitem__. Also (as a separate, though related, feature) add "batching" for list and dict items. If you pickled a dict or list with a million items in the past, it would push a million items onto the stack. It now pushes only 1000 items at a time on the stack, using repeated APPENDS or SETITEMS opcodes. (For lists, I hope that using many short extend() calls doesn't exhibit quadratic behavior.)
* Document __module__.Jeremy Hylton2003-01-311-3/+11

* Provide __module__ attributes for functions defined in C and Python.Jeremy Hylton2003-01-318-18/+114
| | | | | | | | | | | | | | __module__ is the string name of the module the function was defined in, just like __module__ of classes. In some cases, particularly for C functions, the __module__ may be None. Change PyCFunction_New() from a function to a macro, but keep an unused copy of the function around so that we don't change the binary API. Change pickle's save_global() to use whichmodule() if __module__ is None, but add the __module__ logic to whichmodule() since it might be used outside of pickle.
* SF patch #678257 by Geoff Talvola.Guido van Rossum2003-01-311-1/+1
| | | | | In sendall(), do an internal select before each send() call, instead of only for the first one.
* 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.
* I believe this fixesMichael W. Hudson2003-01-311-2/+3
| | | | | | [ 669692 ] pdb user_call breakage What an odd interface! I guess I should have read the docstring, though.
* Change the treatment of positions returned by PEP293Walter Dörwald2003-01-315-41/+122
| | | | | | | | | | | | | | | | 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.
* Pass the object to save_reduce(), so the memoize() call can go intoGuido van Rossum2003-01-311-3/+8

* Make StringIO its own iterator, similar to real files.Guido van Rossum2003-01-311-1/+9

* _PyLong_NumBits(): The definition of this was too specific to the quirkyTim Peters2003-01-313-34/+55
| | | | | | | | | needs of pickling longs. Backed off to a definition that's much easier to understand. The pickler will have to work a little harder, but other uses are more likely to be correct <0.5 wink>. _PyLong_Sign(): New teensy function to characterize a long, as to <0, ==0, or >0.

Move exception formatting to the subprocess; allows subclassing of exceptions, including subclasses created in the shell without introducing excessive complexity in the RPC mechanism. 2. Provide access to linecache from subprocess to support this.

* Change the approach to pickling to use __reduce__ everywhere. MostGuido van Rossum2003-01-302-295/+270
| | | | | | | classes have a __reduce__ that returns (self.__class__, self.__getstate__()). tzinfo.__reduce__() is a bit smarter, calling __getinitargs__ and __getstate__ if they exist, and falling back to __dict__ if it exists and isn't empty.
* pickle.py has a few doctest'ed internal functions, so run their tests.Tim Peters2003-01-301-0/+1

* Check whether the choosen encoding requires byte swappingWalter Dörwald2003-01-302-11/+93
| | | | | | | | | | | | | | | for this iconv() implementation in the init function. For encoding: use a byteswapped version of the input if neccessary. For decoding: byteswap every piece returned by iconv() if neccessary (but not those pieces returned from the callback) Comment out test_sane() in the test script, because whether this works depends on whether byte swapping is neccessary or not (an on Py_UNICODE_SIZE)

* I was in this module anyway, so I did some janitorial things.Michael W. Hudson2003-01-301-17/+14
| | | | | | | | METH_NOARGS functions are still called with two arguments, one NULL, so put that back into the function definitions (I didn't know this until recently). Make get_history_length() METH_NOARGS.
* Add the get_completer() function based on Michael Stone's patch inMichael W. Hudson2003-01-301-0/+17
| | | | | | [ 676342 ] after using pdb readline does not work correctly which is required to fix that bug. So maaybe a bugfix candidate.
* There was a subtle big in save_newobj(): it used self.save_global(t)Guido van Rossum2003-01-301-1/+2
| | | | | | | | | | | | | | | on the type instead of self.save(t). This defeated the purpose of NEWOBJ, because it didn't generate a BINGET opcode when t was already memoized; but moreover, it would generate multiple BINPUT opcodes for the same type! pickletools.dis() doesn't like this. How I found this? I was playing with picklesize.py in the datetime sandbox, and noticed that protocol 2 pickles for multiple objects were in fact larger than protocol 1 pickles! That was suspicious, so I decided to disassemble one of the pickles. This really needs a unit test, but I'm exhausted. I'll be late for work as it is. :-(
* Slight code rearrangement to avoid testing getstate twice.Guido van Rossum2003-01-301-22/+23

* In save_newobj(), if an object's __getnewargs__ and __getstate__ areGuido van Rossum2003-01-301-0/+23
| | | | | | | | | the same function, don't save the state or write a BUILD opcode. This is so that a type (e.g. datetime :-) can support protocol 2 using __getnewargs__ while also supporting protocol 0 and 1 using __getstate__. (Without this, the state would be pickled twice with protocol 2, unless __getstate__ is defined to return None, which breaks protocol 0 and 1.)

* dis(): This had a problem with proto 0 pickles, in that POP sometimesTim Peters2003-01-291-17/+113
| | | | | | | | | | popped a MARK, but without stack emulation the disassembler couldn't know that, and subsequent indentation got hosed. Now the disassembler does do enough stack emulation to catch this. While I was at it, also added lots of sanity checks for other stack operations, and correct use of the memo. This goes (I think) a long way toward being a "pickle verifier" now too.
* Implement appropriate __getnewargs__ for all immutable subclassable builtinGuido van Rossum2003-01-2910-19/+133
| | | | | | | | types. The special handling for these can now be removed from save_newobj(). Add some testing for this. Also add support for setting the 'fast' flag on the Python Pickler class, which suppresses use of the memo.
