* Expose setgroups. Fixes feature request #468116.Martin v. Löwis2001-10-186-4/+62

* Fix error checking done by abstract_issubclass and abstract_isinstance.Neil Schemenauer2001-10-181-44/+61
| | | | | | isinstance() now allows any object as the first argument and a class, a type or something with a __bases__ tuple attribute for the second argument. This closes SF patch #464992.
* Add trivial test cases for RAND_add() and RAND_status().Jeremy Hylton2001-10-181-1/+15
| | | | (The rest of the test cases are trivial, so I don't feel too bad.)
* Expose three OpenSSL API calls for dealing with the PRNG.Jeremy Hylton2001-10-181-0/+67
| | | | | | | | | | | | | | | | | Quoth the OpenSSL RAND_add man page: OpenSSL makes sure that the PRNG state is unique for each thread. On systems that provide /dev/urandom, the randomness device is used to seed the PRNG transparently. However, on all other systems, the application is responsible for seeding the PRNG by calling RAND_add(), RAND_egd(3) or RAND_load_file(3). I decided to expose RAND_add() because it's general and RAND_egd() because it's a useful special case. RAND_load_file() didn't seem to offer much over RAND_add(), so I skipped it. Also supplied RAND_status() which returns true if the PRNG is seeded and false if not.

* Vastly improved stacksize calculation.Jeremy Hylton2001-10-171-18/+51
| | | | | | | | | | | | | | | | | | | | | There are now no known cases where the compiler package computes a stack depth lower than the one computed by the builtin compiler. (To achieve this state, we had to fix bugs in both compilers :-). The chief change is to do the depth calculations with respect to basic blocks. The stack effect of block is calculated. Then the flow graph is traversed using breadth-first search to find the max weight path through the graph. Had to fix the StackDepthTracker to calculate the right info for several opcodes: LOAD_ATTR, CALL_FUNCTION (and friends), MAKE_CLOSURE, and DUP_TOPX. XXX Still need to handle free variables in MAKE_CLOSURE. XXX There are still a lot of places where the computed stack depth is larger than for the builtin compiler. These won't cause the interpreter to overflow the frame, but they waste space.

* Fix computation of stack depth for classdef and closures.Jeremy Hylton2001-10-171-44/+44
| | | | | | | | | | | | | | | | | | | | | | Also minor tweaks to internal routines. Use PyCF_MASK instead of explicit list of flags. For the MAKE_CLOSURE opcode, the number of items popped off the stack depends on both the oparg and the number of free variables for the code object. Fix the code so it accounts for the free variables. In com_classdef(), record an extra pop to account for the STORE call after the BUILD_CLASS. Get rid of some commented out debugging code in com_push() and com_pop(). Factor string resize logic into helper routine com_check_size(). In com_addbyte(), remove redudant if statement after assert. (They test the same condition.) In several routines, use string macros instead of string functions.

* 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.

* 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.
