* cPickle.c: Full support for the new LONG1 and LONG4. Added comments.Tim Peters2003-02-024-41/+227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* 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 Peters2003-02-013-66/+6
| | | | | | 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 Peters2003-01-312-117/+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.

* 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

* 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 Dörwald2003-01-315-41/+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

| | | | | | | | | 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.

* 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.

* 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)
