* Undo needless INCREF chicanery introduced by SF patch #450702.Jeremy Hylton2001-10-161-47/+15
| | | | | | | | | | | | | | Apparently this patch (rev 2.41) replaced all the good old "s#" formats in PyArg_ParseTuple() with "S". Then it did PyString_FromStringAndSize() to get back the values setup by the "s#" format. It also incref'd and decref'd the string obtained by "S" even though the argument tuple had a reference to it. Replace PyString_AsString() calls with PyString_AS_STRING(). A good rule of thumb -- if you never check the return value of PyString_AsString() to see if it's NULL, you ought to be using the macro <wink>.
* Simplify and fix error handling for most cases.Jeremy Hylton2001-10-161-167/+113
| | | | | | | | | | | | | | | | | | Many functions used a local variable called return_error, which was initialized to zero. If an error occurred, it was set to true. Most of the code paths checked were only executed if return_error was false. goto is clearer. The code also seemed to be written under the curious assumption that calling Py_DECREF() on a local variable would assign the variable to NULL. As a result, more of the error-exit code paths returned an object that had a reference count of zero instead of just returning NULL. Fixed the code to explicitly assign NULL after the DECREF. A bit more reformatting, but not much. XXX Need a much better test suite for zlib, since it the current tests don't exercise any of this broken code.

* [ #403753 ] zlib decompress; uncontrollable memory usageJeremy Hylton2001-10-164-12/+113
| | | | | | | | | | | | | Mostly by Toby Dickenson and Titus Brown. Add an optional argument to a decompression object's decompress() method. The argument specifies the maximum length of the return value. If the uncompressed data exceeds this length, the excess data is stored as the unconsumed_tail attribute. (Not to be confused with unused_data, which is a separate issue.) Difference from SF patch: Default value for unconsumed_tail is "" rather than None. It's simpler if the attribute is always a string.

| | | | | | | | | | | | | | | | | object.c, PyObject_Str: Don't try to optimize anything except exact string objects here; in particular, let str subclasses go thru tp_str, same as non-str objects. This allows overrides of tp_str to take effect. stringobject.c: + string_print (str's tp_print): If the argument isn't an exact string object, get one from PyObject_Str. + string_str (str's tp_str): Make a genuine-string copy of the object if it's of a proper str subclass type. str() applied to a str subclass that doesn't override __str__ ends up here. test_descr.py: New str_of_str_subclass() test.

* SF patch #471839: Bug when extensions import extensions (Shane Hathaway)Guido van Rossum2001-10-161-2/+3
| | | | | | | | | | | | | | | | | When an extension imports another extension in its initXXX() function, the variable _Py_PackageContext is prematurely reset to NULL. If the outer extension then calls Py_InitModule(), the extension is installed in sys.modules without its package name. The manifestation of this bug is a "SystemError: _PyImport_FixupExtension: module <package>.<extension> not loaded". To fix this, importdl.c just needs to retain the old value of _Py_PackageContext and restore it after the initXXX() method is called. The attached patch does this. This patch applies to Python 2.1.1 and the current CVS.

* Removed useless code to count the number of calls into the profiler.Fred Drake2001-10-151-51/+177
| | | | | | | | | | | Added support for saving the names of the functions observed into the profile log. Added support for using the profiler to measure coverage without collecting timing information (which is the slow part). Coverage logs can also be substantially smaller than profiling logs where per-line information is being collected. Updated comments on the log format; corrected record type values in some of the record descriptions.
* Avoid deep recursion when reading the header of the log file.Fred Drake2001-10-151-28/+39

* Covert pickle tests to use unittest.Jeremy Hylton2001-10-155-193/+294
| | | | | Extend tests to cover a few more cases. For cPickle, test several of the undocumented features.
* Better fix for core dumps on recursive objects in fast mode.Jeremy Hylton2001-10-151-32/+64
| | | | | | | | | | | | | | | | | | | Raise ValueError when an object contains an arbitrarily nested reference to itself. (The previous fix just produced invalid pickles.) Solution is very much like Py_ReprEnter() and Py_ReprLeave(): fast_save_enter() and fast_save_leave() that tracks the fast_container limit and keeps a fast_memo of objects currently being pickled. The cost of the solution is moderately expensive for deeply nested structures, but it still seems to be faster than normal pickling, based on tests with deeply nested lists. Once FAST_LIMIT is exceeded, the new code is about twice as slow as fast-mode code that doesn't check for recursion. It's still twice as fast as the normal pickling code. In the absence of deeply nested structures, I couldn't measure a difference.
