======================================================================
|
||||
|
||||
|
||||
From 1.5b1 to 1.5b2
|
||||
===================
|
||||
|
||||
- Fixed a bug in cPickle.c that caused it to crash right away because
|
||||
the version string had a different format.
|
||||
|
||||
- Changes in pickle.py and cPickle.c: when unpickling an instance of a
|
||||
class that doesn't define the __getinitargs__() method, the __init__()
|
||||
constructor is no longer called. This makes a much larger group of
|
||||
classes picklable by default, but may occasionally change semantics.
|
||||
To force calling __init__() on unpickling, define a __getinitargs__()
|
||||
method. Other changes too, in particular cPickle now handles classes
|
||||
defined in packages correctly. The same change applies to copying
|
||||
instances with copy.py. The cPickle.c changes and some pickle.py
|
||||
changes are courtesy Jim Fulton.
|
||||
|
||||
- Locale support in he "re" (Perl regular expressions) module. Use
|
||||
the flag re.L (or re.LOCALE) to enable locale-specific matching
|
||||
rules for \w and \b. The in-line syntax for this flag is (?L).
|
||||
|
||||
- The built-in function isinstance(x, y) now also succeeds when y is
|
||||
a type object and type(x) is y.
|
||||
|
||||
- repr() and str() of class and instance objects now reflect the
|
||||
package/module in which the class is defined.
|
||||
|
||||
- Module "ni" has been removed. (If you really need it, it's been
|
||||
renamed to "ni1". Let me know if this causes any problems for you.
|
||||
Package authors are encouraged to write __init__.py files that
|
||||
support both ni and 1.5 package support, so the same version can be
|
||||
used with Python 1.4 as well as 1.5.)
|
||||
|
||||
- The thread module is now automatically included when threads are
|
||||
configured. (You must remove it from your existing Setup file,
|
||||
since it is now in its own Setup.thread file.)
|
||||
|
||||
- New command line option "-x" to skip the first line of the script;
|
||||
handy to make executable scripts on non-Unix platforms.
|
||||
|
||||
- In importdl.c, add the RTLD_GLOBAL to the dlopen() flags. I
|
||||
haven't checked how this affects things, but it should make symbols
|
||||
in one shared library available to the next one.
|
||||
|
||||
- The Windows installer now installs in the "Program Files" folder on
|
||||
the proper volume by default.
|
||||
|
||||
- The Windows configuration adds a new main program, "pythonw", and
|
||||
registers a new extension, ".pyw" that invokes this. This is a
|
||||
pstandard Python interpreter that does not pop up a console window;
|
||||
handy for pure Tkinter applications. All output to the original
|
||||
stdout and stderr is lost; reading from the original stdin yields
|
||||
EOF. Also, both python.exe and pythonw.exe now have a pretty icon
|
||||
(a green snake in a box, courtesy Mark Hammond).
|
||||
|
||||
- Lots of improvements to emacs-mode.el again. See Barry's web page:
|
||||
http://www.python.org/ftp/emacs/pmdetails.html.
|
||||
|
||||
- Lots of improvements and additions to the library reference manual;
|
||||
many by Fred Drake.
|
||||
|
||||
- Doc strings for the following modules: rfc822.py, posixpath.py,
|
||||
ntpath.py, httplib.py. Thanks to Mitch Chapman and Charles Waldman.
|
||||
|
||||
- Some more regression testing.
|
||||
|
||||
- An optional 4th (maxsplit) argument to strop.replace().
|
||||
|
||||
- Fixed handling of maxsplit in string.splitfields().
|
||||
|
||||
- Tweaked os.environ so it can be pickled and copied.
|
||||
|
||||
- The portability problems caused by indented preprocessor commands
|
||||
and C++ style comments should be gone now.
|
||||
|
||||
- In random.py, added Pareto and Weibull distributions.
|
||||
|
||||
- The crypt module is now disabled in Modules/Setup.in by default; it
|
||||
is rarely needed and causes errors on some systems where users often
|
||||
don't know how to deal with those.
|
||||
|
||||
- Some improvements to the _tkinter build line suggested by Case Roole.
|
||||
|
||||
- A full suite of platform specific files for NetBSD 1.x, submitted by
|
||||
Anders Andersen.
|
||||
|
||||
- New Solaris specific header STROPTS.py.
|
||||
|
||||
- Moved a confusing occurrence of *shared* from the comments in
|
||||
Modules/Setup.in (people would enable this one instead of the real
|
||||
one, and get disappointing results).
|
||||
|
||||
- Changed the default mode for directories to be group-writable when
|
||||
the installation process creates them.
|
||||
|
||||
- Check for pthread support in "-l_r" for FreeBSD/NetBSD, and support
|
||||
shared libraries for both.
|
||||
|
||||
- Support FreeBSD and NetBSD in posixfile.py.
|
||||
|
||||
- Support for the "event" command, new in Tk 4.2. By Case Roole.
|
||||
|
||||
- Add Tix_SafeInit() support to tkappinit.c.
|
||||
|
||||
- Various bugs fixed in "re.py" and "pcre.c".
|
||||
|
||||
- Fixed a bug (broken use of the syntax table) in the old "regexpr.c".
|
||||
|
||||
- In frozenmain.c, stdin is made unbuffered too when PYTHONUNBUFFERED
|
||||
is set.
|
||||
|
||||
- Provide default blocksize for retrbinary in ftplib.py (Skip
|
||||
Montanaro).
|
||||
|
||||
- In NT, pick the username up from different places in user.py (Jeff
|
||||
Bauer).
|
||||
|
||||
- Patch to urlparse.urljoin() for ".." and "..#1", Marc Lemburg.
|
||||
|
||||
- Many small improvements to Jeff Rush' OS/2 support.
|
||||
|
||||
- ospath.py is gone; it's been obsolete for so many years now...
|
||||
|
||||
- The reference manual is now set up to prepare better HTML (still
|
||||
using webmaker, alas).
|
||||
|
||||
- Add special handling to /Tools/freeze for Python modules that are
|
||||
imported implicitly by the Python runtime: 'site' and 'exceptions'.
|
||||
|
||||
- Tools/faqwiz 0.8.3 -- add an option to suppress URL processing
|
||||
inside <PRE>, by "Scott".
|
||||
|
||||
- Added ConfigParser.py, a generic parser for sectioned configuration
|
||||
files.
|
||||
|
||||
- In _localemodule.c, LC_MESSAGES is not always defined; put it
|
||||
between #ifdefs.
|
||||
|
||||
- Typo in resource.c: RUSAGE_CHILDERN -> RUSAGE_CHILDREN.
|
||||
|
||||
- Demo/scripts/newslist.py: Fix the way the version number is gotten
|
||||
out of the RCS revision.
|
||||
|
||||
- PyArg_Parse[Tuple] now explicitly check for bad characters at the
|
||||
end of the format string.
|
||||
|
||||
- Revamped PC/example_nt to support VC++ 5.x.
|
||||
|
||||
- <listobject>.sort() now uses a modified quicksort by Raymund Galvin,
|
||||
after studying the GNU libg++ quicksort. This should be much faster
|
||||
if there are lots of duplicates, and otherwise at least as good.
|
||||
|
||||
- Added "uue" as an alias for "uuencode" to mimetools.py. (Hm, the
|
||||
uudecode bug where it complaints about trailing garbage is still there
|
||||
:-( ).
|
||||
|
||||
- pickle.py requires integers in text mode to be in decimal notation
|
||||
(it used to accept octal and hex, even though it would only generate
|
||||
decimal numbers).
|
||||
|
||||
- In string.atof(), don't fail when the "re" module is unavailable.
|
||||
Plug the ensueing security leak by supplying an empty __builtins__
|
||||
directory to eval().
|
||||
|
||||
- A bunch of small fixes and improvements to Tkinter.py.
|
||||
|
||||
- Fixed a buffer overrun in PC/getpathp.c.
