Python 2.1b1 released
by Guido van Rossum 03 Mar '01

03 Mar '01

With great pleasure I announce the release of Python 2.1b1. This is a big step towards the release of Python 2.1; the final release is expected to take place in mid April. Find out all about 2.1b1, including docs and downloads (Windows installer and source tarball), at the 2.1 release page: http://www.python.org/2.1/ WHAT'S NEW? ----------- For the big picture, see Andrew Kuchling's What New in Python 2.1: http://www.amk.ca/python/2.1/ For more detailed release notes, see SourceForge: http://sourceforge.net/project/shownotes.php?release_id=25924 The big news since 2.1a2 was released a month ago: - Nested Scopes (PEP 227)[*] are now optional. They must be enabled by including the statement "from __future__ import nested_scopes" at the beginning of a module (PEP 236). Nested scopes will be a standard feature in Python 2.2. - Compile-time warnings are now generated for a number of conditions that will break or change in meaning when nested scopes are enabled. - The new tool *pydoc* displays module documentation, extracted from doc strings. It works in a text environment as well as in a GUI environment (where it cooperates with a web browser). On Windows, this is in the Start menu as "Module Docs". - Case-sensitive import. On systems with case-insensitive but case-preserving file systems, such as Windows (including Cygwin) and MacOS, import now continues to search the next directory on sys.path when a case mismatch is detected. See PEP 235 for the full scoop. - New platforms. Python 2.1 now fully supports MacOS X, Cygwin, and RISCOS. [*] For PEPs (Python Enhancement Proposals), see the PEP index: http://python.sourceforge.net/peps/ I hope to see you all next week at the Python9 conference in Long Beach, CA: http://www.python9.org --Guido van Rossum (home page: http://www.python.org/~guido/)

python-dev summary, 2001-02-15 - 2001-03-01
by Michael Hudson 02 Mar '01

02 Mar '01

Thanks for all the positive feedback for the last summary! This is a summary of traffic on the python-dev mailing list between Feb 15 and Feb 28 (inclusive) 2001. It is intended to inform the wider Python community of ongoing developments. To comment, just post to python-list(a)python.org or comp.lang.python in the usual way. Give your posting a meaningful subject line, and if it's about a PEP, include the PEP number (e.g. Subject: PEP 201 - Lockstep iteration) All python-dev members are interested in seeing ideas discussed by the community, so don't hesitate to take a stance on a PEP if you have an opinion. This is the second python-dev summary written by Michael Hudson. Previous summaries were written by Andrew Kuchling and can be found at: <http://www.amk.ca/python/dev/> New summaries will appear at: <http://starship.python.net/crew/mwh/summaries/> and will continue to be archived at Andrew's site. Posting distribution (with apologies to mbm) Number of articles in summary: 400 | ]|[ | ]|[ 60 | ]|[ | ]|[ | ]|[ | ]|[ ]|[ | ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ 40 | ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ 20 | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ | ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ ]|[ 0 +-033-037-002-008-006-021-071-037-051-012-002-021-054-045 Thu 15| Sat 17| Mon 19| Wed 21| Fri 23| Sun 25| Tue 27| Fri 16 Sun 18 Tue 20 Thu 22 Sat 24 Mon 26 Wed 28 A slightly quieter week on python-dev. As you can see, most Python developers are too well-adjusted to post much on weekends. Or Mondays. There was a lot of traffic on the bugs, patches and checkins lists in preparation for the upcoming 2.1b1 release. * backwards incompatibility * Most of the posts in the large spike in the middle of the posting distribution were on the subject of backward compatibility. On of the unexpected (by those of us that hadn't thought too hard about it) consequences of nested scopes was that some code using the dreaded "from-module-import-*" code inside functions became ambiguous, and the plan was to ban such code in Python 2.1. This provoked a storm of protest from many quarters, including python-dev and comp.lang.python. If you really want to read all of this, start here: <http://mail.python.org/pipermail/python-dev/2001-February/013003.html> However, as you will know if you read comp.lang.python, PythonLabs took note, and in: <http://mail.python.org/pipermail/python-dev/2001-February/013125.html> Guido announced that the new nested scopes behaviour would be opt-in in 2.1, but code that will break in python 2.2 when nested scopes become the default will produce a warning in 2.1. To get the new behaviour in a module, one will need to put from __future__ import nested_scopes at the top of the module. It is possible this gimmick will be used to introduce further backwards compatible features in the future. * obmalloc * After some more discussion, including Neil Schemenauer pointing out that obmalloc might enable him to make the cycle GC faster, obmalloc was finally checked in. There's a second patch from Vladimir Marangoz implementing a memory profiler. (sorry for the long line) <http://sourceforge.net/tracker/index.php?func=detail&aid=401229&group_id=54…> Opinion was muted about this; as Neil summed up in: <http://mail.python.org/pipermail/python-dev/2001-February/013205.html> noone cares enough to put the time into it and review this patch. Sufficiently violently wielded opnions may swing the day... * pydoc * Ka-Ping Yee checked in his amazing pydoc. pydoc was described in <http://mail.python.org/pipermail/python-dev/2001-January/011538.html> It gives command line and web browser access to Python's documentation, and will be installed as a separate script in 2.1. * other stuff * It is believed that the case-sensitive import issues mentioned in the last summary have been sorted out, although it will be hard to be sure until the beta. The unit-test discussion petered out. Nothing has been checked in yet. The iteraators discussion seems to have disappeared. At least, your author can't find it! Cheers, M.

[Module] pysync 1.2
by Donovan Baarda 02 Mar '01

02 Mar '01

pysync 1.2 ---------- A Python implementation of the rsync algorithm. This is a demonstration implementation of the rsync algorithm in Python. It is not fast and is not optimised. The primary aim is to provide a simple example implementation of the algorithm for reference, so code clarity is more important than performance. Ideas have been liberaly taken from libhsync, xdelta and rsync. Release 1.2 introduced the new zlib-like API, allowing for incremental calculation of deltas and applying patches. The comments at the top of pysync.py explains it all; # Low level API signature calculation sig=calcsig(oldfile) # Low level API rsync style incremental delta calc from sig and newdata delta=rdeltaobj(sig) # or for xdelta style incremental delta calc from oldfile and newdata # delta=xdeltaobj(oldfile) incdelta=delta.calcdelta(newdata) : incdelta=delta.flush() # Low level API applying incremental delta to oldfile to get newdata patch=patchobj(oldfile) newdata=patch.calcpatch(incdelta) : The rdeltaobj.flush() method supports R_SYNC_FLUSH and R_FINISH flush modes that behave the same as their zlib equivalents. Next on the TODO list is incremental signature calculation, and further cleanups. Eventualy I plan to create a md4sum module and move the rolling checksum stuff into C code. The performance has been marginaly hurt by this new API. Interestingly, the python profiler shows that most of the time is wasted performing string-copies when taking slices from input buffers, not actualy doing the rsync. This suggests that significant performance increases might be achievable by re- arranging things a bit, rather than moving python code into C. I have also added a pysync-test.py script for thorough formal testing of pysync. It generates/reuses random test files that make pysync really work hard, verifying that it behaves as it should. Incidentaly, release 1.2 also fixed a rather embarassing bug introduced in release 0.9's adler32.py that corrupted the rolling checksums, resulting in heaps of missed matches. This bug caused seriously bad performance and very large deltas.
