test_logging hangs on Solaris 8 (and 9)
by Mark Favas 26 Apr '03

26 Apr '03

Just confirming Skip's observation - 2.3b1 test_logging (with Neal's patch) passed once on Solaris 9 (gcc 3.2.2) but failed thereafter. No other test failures. Mark Favas

PyRun_* functions
by wesley henwood 26 Apr '03

26 Apr '03

Quote from py docs: "Note also that several of these functions take FILE* parameters. On particular issue which needs to be handled carefully is that the FILE structure for different C libraries can be different and incompatible. Under Windows (at least), it is possible for dynamically linked extensions to actually use different libraries, so care should be taken that FILE* parameters are only passed to these functions if it is certain that they were created by the same library that the Python runtime is using." How does one do this - make sure that they were created with the same lib? Its seems that it would be a good enhancement to remove the FILE pointer parameter from these functions, and just use the file name. For example, change PyRun_SimpleFile( FILE *fp, char *filename) to PyRun_SimpleFile(char *filename). Then no one would have to worry about the incompatibility. _________________________________________________________________

Failin tests on Windows
by Guido van Rossum 26 Apr '03

26 Apr '03

> test_urllib.py is crashing on my fresh WinMe build: > > test_fileno (__main__.urlopen_FileTests) ... FAIL > test_iter (__main__.urlopen_FileTests) ... FAIL > test_read (__main__.urlopen_FileTests) ... FAIL > test_readline (__main__.urlopen_FileTests) ... FAIL > test_readlines (__main__.urlopen_FileTests) ... FAIL Should be fixed now -- I'm writing the file with test data in binary mode. I think that it would be preferably if the socket._fileobject class would actually interpret the mode argument, but it's never done that, so I'm not in a hurry to add this feature to this already hairy class. (Better wait until the new "sio" class -- see sandbox.) > Two of the test cases are failing in test_socket.py > on a fresh build for WinMe: > > testIPv4toString (__main__.GeneralModuleTests) ... ERROR > testStringToIPv4 (__main__.GeneralModuleTests) ... ERROR Fixed too, by skipping the tests of inet_ntop() and inet_pton() when they don't exist. All tests now pass for me, both on Linux (Red Hat 7.8) and Windows (Win 98 second edition). --Guido van Rossum (home page: http://www.python.org/~guido/)

RELEASED: Python 2.3b1
by Guido van Rossum 26 Apr '03

26 Apr '03

Python 2.3b1 is the first beta release of Python 2.3. Much improved since the last alpha, chockfull of things you'd like to check out: http://www.python.org/2.3/ Some highlights of what's new since 2.3a2: - sum() builtin, adds a sequence of numbers, beats reduce(). - csv module, reads comma-separated-value files (and more). - timeit module, times code snippets. - os.walk(), a generator slated to replace os.path.walk(). - platform module, by Marc-Andre Lemburg, returns detailed platform information. For more highlights, see http://www.python.org/2.3/highlights.html New since Python 2.2: - Many new and improved library modules, e.g. sets, heapq, datetime, textwrap, optparse, logging, bsddb, bz2, tarfile, ossaudiodev, and a new random number generator based on the highly acclaimed Mersenne Twister algorithm (with a period of 2**19937-1!). - New builtin enumerate(): an iterator yielding (index, item) pairs. - Extended slices, e.g. "hello"[::-1] returns "olleh". - Universal newlines mode for reading files (converts \r, \n and \r\n all into \n). - Source code encoding declarations. (PEP 263) - Import from zip files. (PEP 273 and PEP 302) - FutureWarning issued for "unsigned" operations on ints. (PEP 237) - Faster list.sort() is now stable. - Unicode filenames on Windows. - Karatsuba long multiplication (running time O(N**1.58) instead of O(N**2)). See also http://www.python.org/doc/2.3b1/whatsnew/ - Andrew Kuchling's description of all important changes since 2.2. We request widespread testing of this release but don't recommend using it for production situations yet. Beta releases contain bugs. New APIs are expected to be stable, and may be changed only if serious deficiencies are found. No new APIs or modules will be added after the first beta release. If you have an important Python application, we strongly recommend that you try it out with a beta release and report any incompatibilities or other problems you may encounter, so that they can be fixed before the final release. To report problems, use the SourceForge bug tracker: http://sourceforge.net/tracker/?group_id=5470&atid=105470 Enjoy! --Guido van Rossum (home page: http://www.python.org/~guido/)

LynxOS4 port: need pre-ncurses curses!
by Duane Voth 25 Apr '03

25 Apr '03

First, Martin, muchas garcias! --export-dynamic was exactly the ticket. Next hurdle: Lynx is clearly hoping curses will go the way of the condor, their implementation is pre ncurses! Comments at the top of Python-2.2.2/Modules/_cursesmodule.c suggest that there was a prior version of Python curses that should be much closer to what LynxOS4 supports. Does anyone have an archived copy of the old _cursesmodule.c? Modules/_cursesmodule.c comments: * Based on prior work by Lance Ellinghaus and Oliver Andrich * Version 1.2 of this module: Copyright 1994 by Lance Ellinghouse, * Cathedral City, California Republic, United States of America. * * Version 1.5b1, heavily extended for ncurses by Oliver Andrich: * Copyright 1996,1997 by Oliver Andrich, Koblenz, Germany. so I guess I'm looking for version 1.2 of _cursesmodule.c. -- Duane Voth duanev(a)io.com -- duanev(a)atlantis.io.com

should sre.Scanner be exposed through re and documented?

25 Apr '03

While moving tests from test_sre to test_re I stumbled upon a simple test for sre.Scanner. This looks fairly cool. Should it be exposed through re and documented? Skip

bz2 module fails to compile on Solaris 8
