These need to be merged into their respective categories for the next release. -- regrtest.py is slightly more verbose, printing the name of each test -as it runs them. +- faqwiz.py: version 0.8; Recognize https:// as URL; <html>...</html> +feature; better install instructions; removed faqmain.py (which was an +older version). + +- nntplib.py: Fixed some bugs reported by Lars Wirzenius (to Debian) +about the treatment of lines starting with '.'. Added a minimal test +function. + +- struct module: ignore most whitespace in format strings. + +- urllib.py: close the socket and temp file in URLopener.retrieve() so +that multiple retrievals using the same connection work. + +- Three new C API functions: + + - int PyErr_GivenExceptionMatches(obj1, obj2) + + Returns 1 if obj1 and obj2 are the same object, or if obj1 is an + instance of type obj2, or of a class derived from obj2 + + - int PyErr_ExceptionMatches(obj) + + Higher level wrapper around PyErr_GivenExceptionMatches() which uses + PyErr_Occurred() as obj1.

If value is None, it uses an empty arg tuple, and if + the value is a tuple, it uses just that. + +- Demo/metaclasses: new demo subdir explains metaclasses (read +index.html in a browser). + +- core interpreter: remove the distinction between tuple and list +unpacking; allow an arbitrary sequence on the right hand side of any +unpack instruction. (UNPACK_LIST and UNPACK_TUPLE now do the same +thing, which should really be called UNPACK_SEQUENCE.) + +- classes: Allow assignments to an instance's __dict__ or __class__, +so you can change ivars (including shared ivars -- shock horror) and +change classes dynamically. Also make the check on read-only +attributes of classes less draconic -- only the specials names +__dict__, __bases__, __name__ and __{get,set,del}attr__ can't be +assigned. + +- Two new built-in functions: issubclass() and isinstance(). Both +take classes as their second arguments. The former takes a class as +the first argument and returns true iff first is second, or is a +subclass of second. The latter takes any object as the first argument +and returns true iff first is an instance of the second, or any +subclass of second. + +- configure: Added configuration tests for presence of alarm(), +pause(), and getpwent(). + +- Doc/Makefile: changed latex2html targets. + +- classes: Reverse the search order for the Don Beaudry hook so that +the first class with an applicable hook wins. Makes more sense. + +- Changed the checks made in Py_Initialize() and Py_Finalize(). It is +now legal to call these more than once. The first call to +Py_Initialize() initializes, the first call to Py_Finalize() +finalizes. There's also a new API, Py_IsInitalized() which checks +whether we are already initialized (in case you want to leave things +as they were). + +- Completely disable the declarations for malloc(), realloc() and +free(). Any 90's C compiler has these in header files, and the tests +to decide whether to suppress the declarations kept failing on some +platforms. + +- *Before* (instead of after) signalmodule.o is added, remove both +intrcheck.o and sigcheck.o. This should get rid of warnings in ar or +ld on various systems. + +- Added reop to PC/config.c + +- configure: Decided to use -Aa -D_HPUX_SOURCE on HP-UX platforms. +Removed outdated HP-UX comments from README. Added Cray T3E comments. + +- Various renames of statically defined functions that had name +conflicts on some systems, e.g. strndup (GNU libc), join (Cray), +roundup (sys/types.h). + +- urllib.py: Interpret three slashes in file: URL as local file (for +Netscape on Windows/Mac). + +- copy.py: Make sure the objects returned by __getinitargs__() are +kept alive (in the memo) to avoid a certain kind of nasty crash. (Not +easily reproducable because it requires a later call to +__getinitargs__() to return a tuple that happens to be allocated at +the same address.) + +- Added definition of AR to toplevel Makefile. Renamed @buildno temp +file to buildno1. + +- Moved Include/assert.h to Parser/assert.h, which seems to be the +only place where it's needed. + +- Alas, the thread support for _tkinter didn't work. Withdrew it. + +- Tweaked the dictionary lookup code again for some more speed +(Vladimir Marangozov). + +- NT build: Changed the way python15.lib is included in the other +projects. Per Mark Hammond's suggestion, add it to the extra libs in +Settings instead of to the project's source files. + +- regrtest.py: Change default verbosity so that there are only three +levels left: -q, default and -v. In default mode, the name of each +test is now printed. -v is the same as the old -vv. -q is more quiet +than the old default mode. + +- Removed the old FAQ from the distribution. You now have to get it +from the web! + +- Removed the PC/make_nt.in file from the distribution; it is no +longer needed. + +- Changed the build sequence so that shared modules are built last. +This fixes things for AIX and doesn't hurt elsewhere. + +- Improved test for GNU MP v1 in mpzmodule.c - fileobject.c: ftell() on Linux discards all buffered data; changed -read() code to use lseek() instead +read() code to use lseek() instead to get the same effect - configure.in, configure, importdl.c: NeXT sharedlib fixes - tupleobject.c: PyTuple_SetItem asserts refcnt==1 -- resource.c: Change how and when to declare getpagesize() and -getrlimit() - -- mpzmodule.c: CPP hack to support GMP 1.x for real +- resource.c: Different strategy regarding whether to declare +getrusage() and getpagesize() -- #ifdef doesn't work, Linux has +conflicting decls in its headers.
