What's new in this release?
|
|
===========================
|
|
|
|
Below is a list of all relevant changes since release 1.5.1. Older
|
|
changes are in the file HISTORY. The most recent changes are listed
|
|
first.
|
|
|
|
A note on attributions: while I have sprinkled some names throughout
|
|
here, I'm grateful to many more people who remain unnamed. You may
|
|
find your name in the ACKS file. If you believe you deserve more
|
|
credit, let me know and I'll add you to the list!
|
|
|
|
|
|
======================================================================
|
|
|
|
|
|
From 1.5.2a2 to 1.5.2b1
|
|
=======================
|
|
|
|
Changes to intrinsics
|
|
---------------------
|
|
|
|
- New extension NotImplementedError, derived from RuntimeError. Not
|
|
used, but recommended use is for "abstract" methods to raise this.
|
|
|
|
- The parser will now spit out a warning or error when -t or -tt is
|
|
used for parser input coming from a string, too.
|
|
|
|
- The code generator now inserts extra SET_LINENO opcodes when
|
|
compiling multi-line argument lists.
|
|
|
|
- When comparing bound methods, use identity test on the objects, not
|
|
equality test.
|
|
|
|
New or improved ports
|
|
---------------------
|
|
|
|
- Chris Herborth has redone his BeOS port; it now works on PowerPC
|
|
(R3/R4) and x86 (R4 only). Threads work too in this port.
|
|
|
|
Renaming
|
|
--------
|
|
|
|
- Thanks to Chris Herborth, the thread primitives now have proper Py*
|
|
names in the source code (they already had those for the linker,
|
|
through some smart macros; but the source still had the old, un-Py
|
|
names).
|
|
|
|
Configuration/build changes
|
|
---------------------------
|
|
|
|
- Improved support for FreeBSD/3.
|
|
|
|
- Check for pthread_detach instead of pthread_create in libc.
|
|
|
|
- The makesetup script now searches EXECINCLUDEPY before INCLUDEPY.
|
|
|
|
- Misc/Makefile.pre.in now also looks at Setup.thread and Setup.local.
|
|
Otherwise modules such as thread didn't get incorporated in extensions.
|
|
|
|
New library modules
|
|
-------------------
|
|
|
|
- codeop.py is a new module that contains the compile_command()
|
|
function that was previously in code.py. This is so that JPython can
|
|
provide its own version of this function, while still sharing the
|
|
higher-level classes in code.py.
|
|
|
|
- turtle.py is a new module for simple turtle graphics. I'm still
|
|
working on it; let me know if you use this to teach Python to children
|
|
or other novices without prior programming experience.
|
|
|
|
Obsoleted library modules
|
|
-------------------------
|
|
|
|
- poly.py and zmod.py have been moved to Lib/lib-old to emphasize
|
|
their status of obsoleteness. They don't do a particularly good job
|
|
and don't seem particularly relevant to the Python core.
|
|
|
|
New tools
|
|
---------
|
|
|
|
- I've added IDLE: my Integrated DeveLopment Environment for Python.
|
|
Requires Tcl/Tk (and Tkinter). Works on Windows and Unix (and should
|
|
work on Macintosh, but I haven't been able to test it there; it does
|
|
depend on new features in 1.5.2 and perhaps even new features in
|
|
1.5.2b1, especially the new code module). This is very much a work in
|
|
progress. I'd like to hear how people like it compared to PTUI (or
|
|
any other IDE they are familiar with).
|
|
|
|
- New tools by Barry Warsaw:
|
|
|
|
= audiopy: controls the Solaris Audio device
|
|
= pynche: The PYthonically Natural Color and Hue Editor
|
|
= world: Print mappings between country names and DNS country codes
|
|
|
|
New demos
|
|
---------
|
|
|
|
- Demo/scripts/beer.py prints the lyrics to an arithmetic drinking
|
|
song.
|
|
|
|
- Demo/tkinter/guido/optionmenu.py shows how to do an option menu in
|
|
Tkinter. (By Fredrik Lundh -- not by me!)
|
|
|
|
Changes to the library
|
|
----------------------
|
|
|
|
- compileall.py now avoids recompiling .py files that haven't changed;
|
|
it adds a -f option to force recompilation.
|
|
|
|
- New version of xmllib.py by Sjoerd Mullender (0.2 with latest
|
|
patches).
|
|
|
|
- nntplib.py: statparse() no longer lowercases the message-id.
|
|
|
|
- types.py: use type(__stdin__) for FileType.
|
|
|
|
- urllib.py: fix translations for filenames with "funny" characters.
|
|
|
|
- cgi.py: In read_multi, allow a subclass to override the class we
|
|
instantiate when we create a recursive instance, by setting the class
|
|
variable 'FieldStorageClass' to the desired class. By default, this
|
|
is set to None, in which case we use self.__class__ (as before).
|
|
Also, a patch by Jim Fulton to pass additional arguments to recursive
|
|
calls to the FieldStorage constructor from its read_multi method.
|
|
|
|
- UserList.py: In __getslice__, use self.__class__ instead of
|
|
UserList.
|
|
|
|
- In SimpleHTTPServer.py, the server specified in test() should be
|
|
BaseHTTPServer.HTTPServer, in case the request handler should want to
|
|
reference the two attributes added by BaseHTTPServer.server_bind. (By
|
|
Jeff Rush, for Bobo). Also open the file in binary mode, so serving
|
|
images from a Windows box might actually work.
|
|
|
|
- In CGIHTTPServer.py, the list of acceptable formats is -split-
|
|
on spaces but -joined- on commas, resulting in double commas
|
|
in the joined text. (By Jeff Rush.)
|
|
|
|
- SocketServer.py, patch by Jeff Bauer: a minor change to declare two
|
|
new threaded versions of Unix Server classes, using the ThreadingMixIn
|
|
class: ThreadingUnixStreamServer, ThreadingUnixDatagramServer.
|
|
|
|
- bdb.py: fix bomb on deleting a temporary breakpoint: there's no
|
|
method do_delete(); do_clear() was meant. By Greg Ward.
|
|
|
|
- getopt.py: accept a non-list sequence for the long options (request
|
|
by Jack Jansen). Because it might be a common mistake to pass a
|
|
single string, this situation is treated separately. Also added
|
|
docstrings (copied from the library manual) and removed the (now
|
|
redundant) module comments.
|
|
|
|
- tempfile.py: improvements to avoid security leaks.
|
|
|
|
- code.py: moved compile_command() to new module codeop.py.
|
|
|
|
- pickle.py: support pickle format 1.3 (binary float added). By Jim
|
|
Fulton. Also get rid of the undocumented obsolete Pickler dump_special
|
|
method.
|
|
|
|
- uu.py: Move 'import sys' to top of module, as noted by Tim Peters.
|
|
|
|
- imaplib.py: fix problem with some versions of IMAP4 servers that
|
|
choose to mix the case in their CAPABILITIES response.
|
|
|
|
- cmp.py: use (f1, f2) as cache key instead of f1 + ' ' + f2. Noted
|
|
by Fredrik Lundh.
|
|
|
|
Changes to extension modules
|
|
----------------------------
|
|
|
|
- More doc strings for several modules were contributed by Chris
|
|
Petrilli: math, cmath, fcntl.
|
|
|
|
- Fixed a bug in zlibmodule.c that could cause core dumps on
|
|
decompression of rarely occurring input.
|
|
|
|
- cPickle.c: new version from Jim Fulton, with Open Source copyright
|
|
notice. Also, initialize self->safe_constructors early on to prevent
|
|
crash in early dealloc.
|
|
|
|
- cStringIO.c: new version from Jim Fulton, with Open Source copyright
|
|
notice. Also fixed a core dump in cStringIO.c when doing seeks.
|
|
|
|
- mpzmodule.c: fix signed character usage in mpz.mpz(stringobjecty).
|
|
|
|
- readline.c: Bernard Herzog pointed out that rl_parse_and_bind
|
|
modifies its argument string (bad function!), so we make a temporary
|
|
copy.
|
|
|
|
- sunaudiodev.c: Barry Warsaw added more smarts to get the device and
|
|
control pseudo-device, per audio(7I).
|
|
|
|
Changes to tools
|
|
----------------
|
|
|
|
- New, improved version of Barry Warsaw's Misc/python-mode.el (editing
|
|
support for Emacs).
|
|
|
|
- tabnanny.py: added a -q ('quiet') option to tabnanny, which causes
|
|
only the names of offending files to be printed.
|
|
|
|
- freeze: when printing missing modules, also print the module they
|
|
were imported from.
|
|
|
|
- untabify.py: patch by Detlef Lannert to implement -t option
|
|
(set tab size).
|
|
|
|
Changes to Tkinter
|
|
------------------
|
|
|
|
- grid_bbox(): support new Tk API: grid bbox ?column row? ?column2
|
|
row2?
|
|
|
|
- _tkinter.c: RajGopal Srinivasan noted that the latest code (1.5.2a2)
|
|
doesn't work when running in a non-threaded environment. He added
|
|
some #ifdefs that fix this.
|
|
|
|
Changes to the Python/C API
|
|
---------------------------
|
|
|
|
- Bumped API version number to 1008 -- enough things have changed!
|
|
|
|
- There's a new macro, PyThreadState_GET(), which does the same work
|
|
as PyThreadState_Get() without the overhead of a function call (it
|
|
also avoids the error check). The two top calling locations of
|
|
PyThreadState_Get() have been changed to use this macro.
|
|
|
|
- All symbols intended for export from a DLL or shared library are now
|
|
marked as such (with the DL_IMPORT() macro) in the header file that
|
|
declares them. This was needed for the BeOS port, and should also
|
|
make some other ports easier. The PC port no longer needs the file
|
|
with exported symbols (PC/python_nt.def). There's also a DL_EXPORT
|
|
macro which is only used for init methods in extension modules, and
|
|
for Py_Main().
|
|
|
|
Invisible changes to internals
|
|
------------------------------
|
|
|
|
- Fixed a bug in new_buffersize() in fileobject.c which could
|
|
return a buffer size that was way too large.
|
|
|
|
- Use PySys_WriteStderr instead of fprintf in most places.
|
|
|
|
- dictobject.c: remove dead code discovered by Vladimir Marangozov.
|
|
|
|
- tupleobject.c: make tuples less hungry -- an extra item was
|
|
allocated but never used. Tip by Vladimir Marangozov.
|
|
|
|
- mymath.h: Metrowerks PRO4 finally fixes the hypot snafu. (Jack
|
|
Jansen)
|
|
|
|
- import.c: Jim Fulton fixes a reference count bug in
|
|
PyEval_GetGlobals.
|
|
|
|
- glmodule.c: check in the changed version after running the stubber
|
|
again -- this solves the conflict with curses over the 'clear' entry
|
|
point much nicer. (Jack Jansen had checked in the changes to cstubs
|
|
eons ago, but I never regenrated glmodule.c :-( )
|
|
|
|
- frameobject.c: fix reference count bug in PyFrame_New. Vladimir
|
|
Marangozov.
|
|
|
|
- stropmodule.c: add a missing DECREF in an error exit. Submitted by
|
|
Jonathan Giddy.
|
|
|
|
|
|
======================================================================
|
|
|
|
|
|
From 1.5.2a1 to 1.5.2a2
|
|
=======================
|
|
|
|
General
|
|
-------
|
|
|
|
- It is now a syntax error to have a function argument without a
|
|
default following one with a default.
|
|
|
|
- __file__ is now set to the .py file if it was parsed (it used to
|
|
always be the .pyc/.pyo file).
|
|
|
|
- Don't exit with a fatal error during initialization when there's a
|
|
problem with the exceptions.py module.
|
|
|
|
- New environment variable PYTHONOPTIMIZE can be used to set -O.
|
|
|
|
- New version of python-mode.el for Emacs.
|
|
|
|
Miscellaneous fixed bugs
|
|
------------------------
|
|
|
|
- No longer print the (confusing) error message about stack underflow
|
|
while compiling.
|
|
|
|
- Some threading and locking bugs fixed.
|
|
|
|
- When errno is zero, report "Error", not "Success".
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
- Documentation will be released separately.
|
|
|
|
- Doc strings added to array and md5 modules by Chris Petrilli.
|
|
|
|
Ports and build procedure
|
|
-------------------------
|
|
|
|
- Stop installing when a move or copy fails.
|
|
|
|
- New version of the OS/2 port code by Jeff Rush.
|
|
|
|
- The makesetup script handles absolute filenames better.
|
|
|
|
- The 'new' module is now enabled by default in the Setup file.
|
|
|
|
- I *think* I've solved the problem with the Linux build blowing up
|
|
sometimes due to a conflict between sigcheck/intrcheck and
|
|
signalmodule.
|
|
|
|
Built-in functions
|
|
------------------
|
|
|
|
- The second argument to apply() can now be any sequence, not just a
|
|
tuple.
|
|
|
|
Built-in types
|
|
--------------
|
|
|
|
- Lists have a new method: L1.extend(L2) is equivalent to the common
|
|
idiom L1[len(L1):] = L2.
|
|
|
|
- Better error messages when a sequence is indexed with a non-integer.
|
|
|
|
- Bettter error message when calling a non-callable object (include
|
|
the type in the message).
|
|
|
|
Python services
|
|
---------------
|
|
|
|
- New version of cPickle.c fixes some bugs.
|
|
|
|
- pickle.py: improved instantiation error handling.
|
|
|
|
- code.py: reworked quite a bit. New base class
|
|
InteractiveInterpreter and derived class InteractiveConsole. Fixed
|
|
several problems in compile_command().
|
|
|
|
- py_compile.py: print error message and continue on syntax errors.
|
|
Also fixed an old bug with the fstat code (it was never used).
|
|
|
|
- pyclbr.py: support submodules of packages.
|
|
|
|
String Services
|
|
---------------
|
|
|
|
- StringIO.py: raise the right exception (ValueError) for attempted
|
|
I/O on closed StringIO objects.
|
|
|
|
- re.py: fixed a bug in subn(), which caused .groups() to fail inside
|
|
the replacement function called by sub().
|
|
|
|
- The struct module has a new format 'P': void * in native mode.
|
|
|
|
Generic OS Services
|
|
-------------------
|
|
|
|
- Module time: Y2K robustness. 2-digit year acceptance depends on
|
|
value of time.accept2dyear, initialized from env var PYTHONY2K,
|
|
default 0. Years 00-68 mean 2000-2068, while 69-99 mean 1969-1999
|
|
(POSIX or X/Open recommendation).
|
|
|
|
- os.path: normpath(".//x") should return "x", not "/x".
|
|
|
|
- getpass.py: fall back on default_getpass() when sys.stdin.fileno()
|
|
doesn't work.
|
|
|
|
- tempfile.py: regenerate the template after a fork() call.
|
|
|
|
Optional OS Services
|
|
--------------------
|
|
|
|
- In the signal module, disable restarting interrupted system calls
|
|
when we have siginterrupt().
|
|
|
|
Debugger
|
|
--------
|
|
|
|
- No longer set __args__; this feature is no longer supported and can
|
|
affect the debugged code.
|
|
|
|
- cmd.py, pdb.py and bdb.py have been overhauled by Richard Wolff, who
|
|
added aliases and some other useful new features, e.g. much better
|
|
breakpoint support: temporary breakpoint, disabled breakpoints,
|
|
breakpoints with ignore counts, and conditions; breakpoints can be set
|
|
on a file before it is loaded.
|
|
|
|
Profiler
|
|
--------
|
|
|
|
- Changes so that JPython can use it. Also fix the calibration code
|
|
so it actually works again
|
|
.
|
|
Internet Protocols and Support
|
|
------------------------------
|
|
|
|
- imaplib.py: new version from Piers Lauder.
|
|
|
|
- smtplib.py: change sendmail() method to accept a single string or a
|
|
list or strings as the destination (commom newbie mistake).
|
|
|
|
- poplib.py: LIST with a msg argument fixed.
|
|
|
|
- urlparse.py: some optimizations for common case (http).
|
|
|
|
- urllib.py: support content-length in info() for ftp protocol;
|
|
support for a progress meter through a third argument to
|
|
urlretrieve(); commented out gopher test (the test site is dead).
|
|
|
|
Internet Data handling
|
|
----------------------
|
|
|
|
- sgmllib.py: support tags with - or . in their name.
|
|
|
|
- mimetypes.py: guess_type() understands 'data' URLs.
|
|
|
|
Restricted Execution
|
|
--------------------
|
|
|
|
- The classes rexec.RModuleLoader and rexec.RModuleImporter no
|
|
longer exist.
|
|
|
|
Tkinter
|
|
-------
|
|
|
|
- When reporting an exception, store its info in sys.last_*. Also,
|
|
write all of it to stderr.
|
|
|
|
- Added NS, EW, and NSEW constants, for grid's sticky option.
|
|
|
|
- Fixed last-minute bug in 1.5.2a1 release: need to include "mytime.h".
|
|
|
|
- Make bind variants without a sequence return a tuple of sequences
|
|
(formerly it returned a string, which wasn't very convenient).
|
|
|
|
- Add image commands to the Text widget (these are new in Tk 8.0).
|
|
|
|
- Added new listbox and canvas methods: {xview,yview}_{scroll,moveto}.)
|
|
|
|
- Improved the thread code (but you still can't call update() from
|
|
another thread on Windows).
|
|
|
|
- Fixed unnecessary references to _default_root in the new dialog
|
|
modules.
|
|
|
|
- Miscellaneous problems fixed.
|
|
|
|
|
|
Windows General
|
|
---------------
|
|
|
|
- Call LoadLibraryEx(..., ..., LOAD_WITH_ALTERED_SEARCH_PATH) to
|
|
search for dependent dlls in the directory containing the .pyd.
|
|
|
|
- In debugging mode, call DebugBreak() in Py_FatalError().
|
|
|
|
Windows Installer
|
|
-----------------
|
|
|
|
- Install zlib.dll in the DLLs directory instead of in the win32
|
|
system directory, to avoid conflicts with other applications that have
|
|
their own zlib.dll.
|
|
|
|
Test Suite
|
|
----------
|
|
|
|
- test_long.py: new test for long integers, by Tim Peters.
|
|
|
|
- regrtest.py: improved so it can be used for other test suites as
|
|
well.
|
|
|
|
- test_strftime.py: use re to compare test results, to support legal
|
|
variants (e.g. on Linux).
|
|
|
|
Tools and Demos
|
|
---------------
|
|
|
|
- Four new scripts in Tools/scripts: crlf.py and lfcr.py (to
|
|
remove/add Windows style '\r\n' line endings), untabify.py (to remove
|
|
tabs), and rgrep.yp (reverse grep).
|
|
|
|
- Improvements to Tools/freeze/. Each Python module is now written to
|
|
its own C file. This prevents some compilers or assemblers from
|
|
blowing up on large frozen programs, and saves recompilation time if
|
|
only a few modules are changed. Other changes too, e.g. new command
|
|
line options -x and -i.
|
|
|
|
- Much improved (and smaller!) version of Tools/scripts/mailerdaemon.py.
|
|
|
|
Python/C API
|
|
------------
|
|
|
|
- New mechanism to support extensions of the type object while
|
|
remaining backward compatible with extensions compiled for previous
|
|
versions of Python 1.5. A flags field indicates presence of certain
|
|
fields.
|
|
|
|
- Addition to the buffer API to differentiate access to bytes and
|
|
8-bit characters (in anticipation of Unicode characters).
|
|
|
|
- New argument parsing format t# ("text") to indicate 8-bit
|
|
characters; s# simply means 8-bit bytes, for backwards compatibility.
|
|
|
|
- New object type, bufferobject.c is an example and can be used to
|
|
create buffers from memory.
|
|
|
|
- Some support for 64-bit longs, including some MS platforms.
|
|
|
|
- Many calls to fprintf(stderr, ...) have been replaced with calls to
|
|
PySys_WriteStderr(...).
|
|
|
|
- The calling context for PyOS_Readline() has changed: it must now be
|
|
called with the interpreter lock held! It releases the lock around
|
|
the call to the function pointed to by PyOS_ReadlineFunctionPointer
|
|
(default PyOS_StdioReadline()).
|
|
|
|
- New APIs PyLong_FromVoidPtr() and PyLong_AsVoidPtr().
|
|
|
|
- Renamed header file "thread.h" to "pythread.h".
|
|
|
|
- The code string of code objects may now be anything that supports the
|
|
buffer API.
|
|
|
|
|
|
======================================================================
|
|
|
|
|
|
From 1.5.1 to 1.5.2a1
|
|
=====================
|
|
|
|
General
|
|
-------
|
|
|
|
- When searching for the library, a landmark that is a compiled module
|
|
(string.pyc or string.pyo) is also accepted.
|
|
|
|
- When following symbolic links to the python executable, use a loop
|
|
so that a symlink to a symlink can work.
|
|
|
|
- Added a hack so that when you type 'quit' or 'exit' at the
|
|
interpreter, you get a friendly explanation of how to press Ctrl-D (or
|
|
Ctrl-Z) to exit.
|
|
|
|
- New and improved Misc/python-mode.el (Python mode for Emacs).
|
|
|
|
- Revert a new feature in Unix dynamic loading: for one or two
|
|
revisions, modules were loaded using the RTLD_GLOBAL flag. It turned
|
|
out to be a bad idea.
|
|
|
|
Miscellaneous fixed bugs
|
|
------------------------
|
|
|
|
- All patches on the patch page have been integrated. (But much more
|
|
has been done!)
|
|
|
|
- Several memory leaks plugged (e.g. the one for classes with a
|
|
__getattr__ method).
|
|
|
|
- Removed the only use of calloc(). This triggered an obscure bug on
|
|
multiprocessor Sparc Solaris 2.6.
|
|
|
|
- Fix a peculiar bug that would allow "import sys.time" to succeed
|
|
(believing the built-in time module to be a part of the sys package).
|
|
|
|
- Fix a bug in the overflow checking when converting a Python long to
|
|
a C long (failed to convert -2147483648L, and some other cases).
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
- Doc strings have been added to many extension modules: __builtin__,
|
|
errno, select, signal, socket, sys, thread, time. Also to methods of
|
|
list objects (try [].append.__doc__). A doc string on a type will now
|
|
automatically be propagated to an instance if the instance has methods
|
|
that are accessed in the usual way.
|
|
|
|
- The documentation has been expanded and the formatting improved.
|
|
(Remember that the documentation is now unbundled and has its own
|
|
release cycle though; see http://www.python.org/doc/.)
|
|
|
|
- Added Misc/Porting -- a mini-FAQ on porting to a new platform.
|
|
|
|
Ports and build procedure
|
|
-------------------------
|
|
|
|
- The BeOS port is now integrated. Courtesy Chris Herborth.
|
|
|
|
- Symbol files for FreeBSD 2.x and 3.x have been contributed
|
|
(Lib/plat-freebsd[23]/*).
|
|
|
|
- Support HPUX 10.20 DCE threads.
|
|
|
|
- Finally fixed the configure script so that (on SGI) if -OPT:Olimit=0
|
|
works, it won't also use -Olimit 1500 (which gives a warning for every
|
|
file). Also support the SGI_ABI environment variable better.
|
|
|
|
- The makesetup script now understands absolute pathnames ending in .o
|
|
in the module -- it assumes it's a file for which we have no source.
|
|
|
|
- Other miscellaneous improvements to the configure script and
|
|
Makefiles.
|
|
|
|
- The test suite now uses a different sound sample.
|
|
|
|
Built-in functions
|
|
------------------
|
|
|
|
- Better checks for invalid input to int(), long(), string.atoi(),
|
|
string.atol(). (Formerly, a sign without digits would be accepted as
|
|
a legal ways to spell zero.)
|
|
|
|
- Changes to map() and filter() to use the length of a sequence only
|
|
as a hint -- if an IndexError happens earlier, take that. (Formerly,
|
|
this was considered an error.)
|
|
|
|
- Experimental feature in getattr(): a third argument can specify a
|
|
default (instead of raising AttributeError).
|
|
|
|
- Implement round() slightly different, so that for negative ndigits
|
|
no additional errors happen in the last step.
|
|
|
|
- The open() function now adds the filename to the exception when it
|
|
fails.
|
|
|
|
Built-in exceptions
|
|
-------------------
|
|
|
|
- New standard exceptions EnvironmentError and PosixError.
|
|
EnvironmentError is the base class for IOError and PosixError;
|
|
PosixError is the same as os.error. All this so that either exception
|
|
class can be instantiated with a third argument indicating a filename.
|
|
The built-in function open() and most os/posix functions that take a
|
|
filename argument now use this.
|
|
|
|
Built-in types
|
|
--------------
|
|
|
|
- List objects now have an experimental pop() method; l.pop() returns
|
|
and removes the last item; l.pop(i) returns and removes the item at
|
|
i. Also, the sort() method is faster again. Sorting is now also
|
|
safer: it is impossible for the sorting function to modify the list
|
|
while the sort is going on (which could cause core dumps).
|
|
|
|
- Changes to comparisons: numbers are now smaller than any other type.
|
|
This is done to prevent the circularity where [] < 0L < 1 < [] is
|
|
true. As a side effect, cmp(None, 0) is now positive instead of
|
|
negative. This *shouldn't* affect any working code, but I've found
|
|
that the change caused several "sleeping" bugs to become active, so
|
|
beware!
|
|
|
|
- Instance methods may now have other callable objects than just
|
|
Python functions as their im_func. Use new.instancemethod() or write
|
|
your own C code to create them; new.instancemethod() may be called
|
|
with None for the instance to create an unbound method.
|
|
|
|
- Assignment to __name__, __dict__ or __bases__ of a class object is
|
|
now allowed (with stringent type checks); also allow assignment to
|
|
__getattr__ etc. The cached values for __getattr__ etc. are
|
|
recomputed after such assignments (but not for derived classes :-( ).
|
|
|
|
- Allow assignment to some attributes of function objects: func_code,
|
|
func_defaults and func_doc / __doc__. (With type checks except for
|
|
__doc__ / func_doc .)
|
|
|
|
Python services
|
|
---------------
|
|
|
|
- New tests (in Lib/test): reperf.py (regular expression benchmark),
|
|
sortperf.py (list sorting benchmark), test_MimeWriter.py (test case
|
|
for the MimeWriter module).
|
|
|
|
- Generalized test/regrtest.py so that it is useful for testing other
|
|
packages.
|
|
|
|
- The ihooks.py module now understands package imports.
|
|
|
|
- In code.py, add a class that subsumes Fredrik Lundh's
|
|
PythonInterpreter class. The interact() function now uses this.
|
|
|
|
- In rlcompleter.py, in completer(), return None instead of raising an
|
|
IndexError when there are no more completions left.
|
|
|
|
- Fixed the marshal module to test for certain common kinds of invalid
|
|
input. (It's still not foolproof!)
|
|
|
|
- In the operator module, add an alias (now the preferred name)
|
|
"contains" for "sequenceincludes".
|
|
|
|
String Services
|
|
---------------
|
|
|
|
- In the string and strop modules, in the replace() function, treat an
|
|
empty pattern as an error (since it's not clear what was meant!).
|
|
|
|
- Some speedups to re.py, especially the string substitution and split
|
|
functions. Also added new function/method findall(), to find all
|
|
occurrences of a given substring.
|
|
|
|
- In cStringIO, add better argument type checking and support the
|
|
readonly 'closed' attribute (like regular files).
|
|
|
|
- In the struct module, unsigned 1-2 byte sized formats no longer
|
|
result in long integer values.
|
|
|
|
Miscellaneous services
|
|
----------------------
|
|
|
|
- In whrandom.py, added new method and function randrange(), same as
|
|
choice(range(start, stop, step)) but faster. This addresses the
|
|
problem that randint() was accidentally defined as taking an inclusive
|
|
range. Also, randint(a, b) is now redefined as randrange(a, b+1),
|
|
adding extra range and type checking to its arguments!
|
|
|
|
- Add some semi-thread-safety to random.gauss() (it used to be able to
|
|
crash when invoked from separate threads; now the worst it can do is
|
|
give a duplicate result occasionally).
|
|
|
|
- Some restructuring and generalization done to cmd.py.
|
|
|
|
- Major upgrade to ConfigParser.py; converted to using 're', added new
|
|
exceptions, support underscore in section header and option name. No
|
|
longer add 'name' option to every section; instead, add '__name__'.
|
|
|
|
- In getpass.py, don't use raw_input() to ask for the password -- we
|
|
don't want it to show up in the readline history! Also don't catch
|
|
interrupts (the try-finally already does all necessary cleanup).
|
|
|
|
Generic OS Services
|
|
-------------------
|
|
|
|
- New functions in os.py: makedirs(), removedirs(), renames(). New
|
|
variable: linesep (the line separator as found in binary files,
|
|
i.e. '\n' on Unix, '\r\n' on DOS/Windows, '\r' on Mac. Do *not* use
|
|
this with files opened in (default) text mode; the line separator used
|
|
will always be '\n'!
|
|
|
|
- Changes to the 'os.path' submodule of os.py: added getsize(),
|
|
getmtime(), getatime() -- these fetch the most popular items from the
|
|
stat return tuple.
|
|
|
|
- In the time module, add strptime(), if it exists. (This parses a
|
|
time according to a format -- the inverse of strftime().) Also,
|
|
remove the call to mktime() from strftime() -- it messed up the
|
|
formatting of some non-local times.
|
|
|
|
- In the socket module, added a new function gethostbyname_ex().
|
|
Also, don't use #ifdef to test for some symbols that are enums on some
|
|
platforms (and should exist everywhere).
|
|
|
|
Optional OS Services
|
|
--------------------
|
|
|
|
- Some fixes to gzip.py. In particular, the readlines() method now
|
|
returns the lines *with* trailing newline characters, like readlines()
|
|
of regular file objects. Also, it didn't work together with cPickle;
|
|
fixed that.
|
|
|
|
- In whichdb.py, support byte-swapped dbhash (bsddb) files.
|
|
|
|
- In anydbm.py, look at the type of an existing database to determine
|
|
which module to use to open it. (The anydbm.error exception is now a
|
|
tuple.)
|
|
|
|
Unix Services
|
|
-------------
|
|
|
|
- In the termios module, in tcsetattr(), initialize the structure vy
|
|
calling tcgetattr().
|
|
|
|
- Added some of the "wait status inspection" macros as functions to
|
|
the posix module (and thus to the os module): WEXITSTATUS(),
|
|
WIFEXITED(), WIFSIGNALED(), WIFSTOPPED(), WSTOPSIG(), WTERMSIG().
|
|
|
|
- In the syslog module, make the default facility more intuitive
|
|
(matching the docs).
|
|
|
|
Debugger
|
|
--------
|
|
|
|
- In pdb.py, support for setting breaks on files/modules that haven't
|
|
been loaded yet.
|
|
|
|
Internet Protocols and Support
|
|
------------------------------
|
|
|
|
- Changes in urllib.py; sped up unquote() and quote(). Fixed an
|
|
obscure bug in quote_plus(). Added urlencode(dict) -- convenience
|
|
function for sending a POST request with urlopen(). Use the getpass
|
|
module to ask for a password. Rewrote the (test) main program so that
|
|
when used as a script, it can retrieve one or more URLs to stdout.
|
|
Use -t to run the self-test. Made the proxy code work again.
|
|
|
|
- In cgi.py, treat "HEAD" the same as "GET", so that CGI scripts don't
|
|
fail when someone asks for their HEAD. Also, for POST, set the
|
|
default content-type to application/x-www-form-urlencoded. Also, in
|
|
FieldStorage.__init__(), when method='GET', always get the query
|
|
string from environ['QUERY_STRING'] or sys.argv[1] -- ignore an
|
|
explicitly passed in fp.
|
|
|
|
- The smtplib.py module now supports ESMTP and has improved standard
|
|
compliance, for picky servers.
|
|
|
|
- Improved imaplib.py.
|
|
|
|
- Fixed UDP support in SocketServer.py (it never worked).
|
|
|
|
- Fixed a small bug in CGIHTTPServer.py.
|
|
|
|
Internet Data handling
|
|
----------------------
|
|
|
|
- In rfc822.py, add a new class AddressList. Also support a new
|
|
overridable method, isheader(). Also add a get() method similar to
|
|
dictionaries (and make getheader() an alias for it). Also, be smarter
|
|
about seekable (test whether fp.tell() works) and test for presence of
|
|
unread() method before trying seeks.
|
|
|
|
- In sgmllib.py, restore the call to report_unbalanced() that was lost
|
|
long ago. Also some other improvements: handle <? processing
|
|
instructions >, allow . and - in entity names, and allow \r\n as line
|
|
separator.
|
|
|
|
- Some restructuring and generalization done to multifile.py; support
|
|
a 'seekable' flag.
|
|
|
|
Restricted Execution
|
|
--------------------
|
|
|
|
- Improvements to rexec.py: package support; support a (minimal)
|
|
sys.exc_info(). Also made the (test) main program a bit fancier (you
|
|
can now use it to run arbitrary Python scripts in restricted mode).
|
|
|
|
Tkinter
|
|
-------
|
|
|
|
- On Unix, Tkinter can now safely be used from a multi-threaded
|
|
application. (Formerly, no threads would make progress while
|
|
Tkinter's mainloop() was active, because it didn't release the Python
|
|
interpreter lock.) Unfortunately, on Windows, threads other than the
|
|
main thread should not call update() or update_idletasks() because
|
|
this will deadlock the application.
|
|
|
|
- An interactive interpreter that uses readline and Tkinter no longer
|
|
uses up all available CPU time.
|
|
|
|
- Even if readline is not used, Tk windows created in an interactive
|
|
interpreter now get continuously updated. (This even works in Windows
|
|
as long as you don't hit a key.)
|
|
|
|
- New demos in Demo/tkinter/guido/: brownian.py, redemo.py, switch.py.
|
|
|
|
- No longer register Tcl_finalize() as a low-level exit handler. It
|
|
may call back into Python, and that's a bad idea.
|
|
|
|
- Allow binding of Tcl commands (given as a string).
|
|
|
|
- Some minor speedups; replace explicitly coded getint() with int() in
|
|
most places.
|
|
|
|
- In FileDialog.py, remember the directory of the selected file, if
|
|
given.
|
|
|
|
- Change the names of all methods in the Wm class: they are now
|
|
wm_title(), etc. The old names (title() etc.) are still defined as
|
|
aliases.
|
|
|
|
- Add a new method of interpreter objects, interpaddr(). This returns
|
|
the address of the Tcl interpreter object, as an integer. Not very
|
|
useful for the Python programmer, but this can be called by another C
|
|
extension that needs to make calls into the Tcl/Tk C API and needs to
|
|
get the address of the Tcl interpreter object. A simple cast of the
|
|
return value to (Tcl_Interp *) will do the trick.
|
|
|
|
Windows General
|
|
---------------
|
|
|
|
- Don't insist on proper case for module source files if the filename
|
|
is all uppercase (e.g. FOO.PY now matches foo; but FOO.py still
|
|
doesn't). This should address problems with this feature on
|
|
oldfashioned filesystems (Novell servers?).
|
|
|
|
Windows Library
|
|
---------------
|
|
|
|
- os.environ is now all uppercase, but accesses are case insensitive,
|
|
and the putenv() calls made as a side effect of changing os.environ
|
|
are case preserving.
|
|
|
|
- Removed samefile(), sameopenfile(), samestat() from os.path (aka
|
|
ntpath.py) -- these cannot be made to work reliably (at least I
|
|
wouldn't know how).
|
|
|
|
- Fixed os.pipe() so that it returns file descriptors acceptable to
|
|
os.read() and os.write() (like it does on Unix), rather than Windows
|
|
file handles.
|
|
|
|
- Added a table of WSA error codes to socket.py.
|
|
|
|
- In the select module, put the (huge) file descriptor arrays on the
|
|
heap.
|
|
|
|
- The getpass module now raises KeyboardInterrupt when it sees ^C.
|
|
|
|
- In mailbox.py, fix tell/seek when using files opened in text mode.
|
|
|
|
- In rfc822.py, fix tell/seek when using files opened in text mode.
|
|
|
|
- In the msvcrt extension module, release the interpreter lock for
|
|
calls that may block: _locking(), _getch(), _getche(). Also fix a
|
|
bogus error return when open_osfhandle() doesn't have the right
|
|
argument list.
|
|
|
|
Windows Installer
|
|
-----------------
|
|
|
|
- The registry key used is now "1.5" instead of "1.5.x" -- so future
|
|
versions of 1.5 and Mark Hammond's win32all installer don't need to be
|
|
resynchronized.
|
|
|
|
Windows Tools
|
|
-------------
|
|
|
|
- Several improvements to freeze specifically for Windows.
|
|
|
|
Windows Build Procedure
|
|
-----------------------
|
|
|
|
- The VC++ project files and the WISE installer have been moved to the
|
|
PCbuild subdirectory, so they are distributed in the same subdirectory
|
|
where they must be used. This avoids confusion.
|
|
|
|
- New project files for Windows 3.1 port by Jim Ahlstrom.
|
|
|
|
- Got rid of the obsolete subdirectory PC/setup_nt/.
|
|
|
|
- The projects now use distinct filenames for the .exe, .dll, .lib and
|
|
.pyd files built in debug mode (by appending "_d" to the base name,
|
|
before the extension). This makes it easier to switch between the two
|
|
and get the right versions. There's a pragma in config.h that directs
|
|
the linker to include the appropriate .lib file (so python15.lib no
|
|
longer needs to be explicit in your project).
|
|
|
|
- The installer now installs more files (e.g. config.h). The idea is
|
|
that you shouldn't need the source distribution if you want build your
|
|
own extensions in C or C++.
|
|
|
|
Tools and Demos
|
|
---------------
|
|
|
|
- New script nm2def.py by Marc-Andre Lemburg, to construct
|
|
PC/python_nt.def automatically (some hand editing still required).
|
|
|
|
- New tool ndiff.py: Tim Peters' text diffing tool.
|
|
|
|
- Various and sundry improvements to the freeze script.
|
|
|
|
- The script texi2html.py (which was part of the Doc tree but is no
|
|
longer used there) has been moved to the Tools/scripts subdirectory.
|
|
|
|
- Some generalizations in the webchecker code. There's now a
|
|
primnitive gui for websucker.py: wsgui.py. (In Tools/webchecker/.)
|
|
|
|
- The ftpmirror.py script now handles symbolic links properly, and
|
|
also files with multiple spaces in their names.
|
|
|
|
- The 1.5.1 tabnanny.py suffers an assert error if fed a script whose
|
|
last line is both indented and lacks a newline. This is now fixed.
|
|
|
|
Python/C API
|
|
------------
|
|
|
|
- Added missing prototypes for PyEval_CallFunction() and
|
|
PyEval_CallMethod().
|
|
|
|
- New macro PyList_SET_ITEM().
|
|
|
|
- New macros to access object members for PyFunction, PyCFunction
|
|
objects.
|
|
|
|
- New APIs PyImport_AppendInittab() an PyImport_ExtendInittab() to
|
|
dynamically add one or many entries to the table of built-in modules.
|
|
|
|
- New macro Py_InitModule3(name, methods, doc) which calls
|
|
Py_InitModule4() with appropriate arguments. (The -4 variant requires
|
|
you to pass an obscure version number constant which is always the same.)
|
|
|
|
- New APIs PySys_WriteStdout() and PySys_WriteStderr() to write to
|
|
sys.stdout or sys.stderr using a printf-like interface. (Used in
|
|
_tkinter.c, for example.)
|
|
|
|
- New APIs for conversion between Python longs and C 'long long' if
|
|
your compiler supports it.
|
|
|
|
- PySequence_In() is now called PySequence_Contains().
|
|
(PySequence_In() is still supported for b/w compatibility; it is
|
|
declared obsolete because its argument order is confusing.)
|
|
|
|
- PyDict_GetItem() and PyDict_GetItemString() are changed so that they
|
|
*never* raise an exception -- (even if the hash() fails, simply clear
|
|
the error). This was necessary because there is lots of code out
|
|
there that already assumes this.
|
|
|
|
- Changes to PySequence_Tuple() and PySequence_List() to use the
|
|
length of a sequence only as a hint -- if an IndexError happens
|
|
earlier, take that. (Formerly, this was considered an error.)
|
|
|
|
- Reformatted abstract.c to give it a more familiar "look" and fixed
|
|
many error checking bugs.
|
|
|
|
- Add NULL pointer checks to all calls of a C function through a type
|
|
object and extensions (e.g. nb_add).
|
|
|
|
- The code that initializes sys.path now calls Py_GetPythonHome()
|
|
instead of getenv("PYTHONHOME"). This, together with the new API
|
|
Py_SetPythonHome(), makes it easier for embedding applications to
|
|
change the notion of Python's "home" directory (where the libraries
|
|
etc. are sought).
|
|
|
|
- Fixed a very old bug in the parsing of "O?" format specifiers.
|
|
