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!
|
|
|
|
(In the sake of steramlining the release process, I'm now using output
|
|
from rcs2log. This gives complete disclosure but is more verbose and
|
|
requires more effort to read. Let me know if this is acceptable.

From 1.5.2c1 to 1.5.2 (final)
|
|
=============================
|
|
|
|
Tue Apr 13 15:44:49 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* PCbuild/python15.wse: Bump version to 1.5.2 (final)
|
|
|
|
* PCbuild/python15.dsp: Added shamodule.c
|
|
|
|
* PC/config.c: Added sha module!
|
|
|
|
* README, Include/patchlevel.h: Prepare for final release.
|
|
|
|
* Misc/ACKS:
|
|
More (Cameron Laird is honorary; the others are 1.5.2c1 testers).
|
|
|
|
* Python/thread_solaris.h:
|
|
While I can't really test this thoroughly, Pat Knight and the Solaris
|
|
man pages suggest that the proper thing to do is to add THR_NEW_LWP to
|
|
the flags on thr_create(), and that there really isn't a downside, so
|
|
I'll do that.
|
|
|
|
* Misc/ACKS:
|
|
Bunch of new names who helped iron out the last wrinkles of 1.5.2.
|
|
|
|
* PC/python_nt.rc:
|
|
Bump the myusterious M$ version number from 1,5,2,1 to 1,5,2,3.
|
|
(I can't even display this on NT, maybe Win/98 can?)
|
|
|
|
* Lib/pstats.py:
|
|
Fix mysterious references to jprofile that were in the source since
|
|
its creation. I'm assuming these were once valid references to "Jim
|
|
Roskind's profile"...
|
|
|
|
* Lib/Attic/threading_api.py:
|
|
Removed; since long subsumed in Doc/lib/libthreading.tex
|
|
|
|
* Modules/socketmodule.c:
|
|
Put back __osf__ support for gethostbyname_r(); the real bug was that
|
|
it was being used even without threads. This of course might be an
|
|
all-platform problem so now we only use the _r variant when we are
|
|
using threads.
|
|
|
|
Mon Apr 12 22:51:20 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Modules/cPickle.c:
|
|
Fix accidentally reversed NULL test in load_mark(). Suggested by
|
|
Tamito Kajiyama. (This caused a bug only on platforms where malloc(0)
|
|
returns NULL.)
|
|
|
|
* README:
|
|
Add note about popen2 problem on Linux noticed by Pablo Bleyer.
|
|
|
|
* README: Add note about -D_REENTRANT for HP-UX 10.20.
|
|
|
|
* Modules/Makefile.pre.in: 'clean' target should remove hassignal.
|
|
|
|
* PC/Attic/vc40.mak, PC/readme.txt:
|
|
Remove all VC++ info (except VC 1.5) from readme.txt;
|
|
remove the VC++ 4.0 project file; remove the unused _tkinter extern defs.
|
|
|
|
* README: Clarify PC build instructions (point to PCbuild).
|
|
|
|
* Modules/zlibmodule.c: Cast added by Jack Jansen (for Mac port).
|
|
|
|
* Lib/plat-sunos5/CDIO.py, Lib/plat-linux2/CDROM.py:
|
|
Forgot to add this file. CDROM device parameters.
|
|
|
|
* Lib/gzip.py: Two different changes.
|
|
|
|
1. Jack Jansen reports that on the Mac, the time may be negative, and
|
|
solves this by adding a write32u() function that writes an unsigned
|
|
long.
|
|
|
|
2. On 64-bit platforms the CRC comparison fails; I've fixed this by
|
|
casting both values to be compared to "unsigned long" i.e. modulo
|
|
0x100000000L.

|
|
|
Sat Apr 10 18:42:02 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* PC/Attic/_tkinter.def: No longer needed.
|
|
|
|
* Misc/ACKS: Correct missed character in Andrew Dalke's name.
|
|
|
|
* README: Add DEC Ultrix notes (from Donn Cave's email).
|
|
|
|
* configure: The usual
|
|
|
|
* configure.in:
|
|
Quote a bunch of shell variables used in test, related to long-long.
|
|
|
|
* Objects/fileobject.c, Modules/shamodule.c, Modules/regexpr.c:
|
|
casts for picky compilers.
|
|
|
|
* Modules/socketmodule.c:
|
|
3-arg gethostbyname_r doesn't really work on OSF/1.
|
|
|
|
* PC/vc15_w31/_.c, PC/vc15_lib/_.c, Tools/pynche/__init__.py:
|
|
Avoid totally empty files.
|
|
|
|
Fri Apr 9 14:56:35 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Tools/scripts/fixps.py: Use re instead of regex.
|
|
Don't rewrite the file in place.
|
|
(Reported by Andy Dustman.)
|
|
|
|
* Lib/netrc.py, Lib/shlex.py: Get rid of #! line
|
|
|
|
Thu Apr 8 23:13:37 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* PCbuild/python15.wse: Use the Tcl 8.0.5 installer.
|
|
Add a variable %_TCL_% that makes it easier to switch to a different version.
|
|
|
|
|
|
======================================================================
|
|
|
|
|
|
From 1.5.2b2 to 1.5.2c1
|
|
=======================
|
|
|
|
Thu Apr 8 23:13:37 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* PCbuild/python15.wse:
|
|
Release 1.5.2c1. Add IDLE and Uninstall to program group.
|
|
Don't distribute zlib.dll. Tweak some comments.
|
|
|
|
* PCbuild/zlib.dsp: Now using static zlib 1.1.3
|
|
|
|
* Lib/dos-8x3/userdict.py, Lib/dos-8x3/userlist.py, Lib/dos-8x3/test_zli.py, Lib/dos-8x3/test_use.py, Lib/dos-8x3/test_pop.py, Lib/dos-8x3/test_pic.py, Lib/dos-8x3/test_ntp.py, Lib/dos-8x3/test_gzi.py, Lib/dos-8x3/test_fcn.py, Lib/dos-8x3/test_cpi.py, Lib/dos-8x3/test_bsd.py, Lib/dos-8x3/posixfil.py, Lib/dos-8x3/mimetype.py, Lib/dos-8x3/nturl2pa.py, Lib/dos-8x3/compilea.py, Lib/dos-8x3/exceptio.py, Lib/dos-8x3/basehttp.py:
|
|
The usual
|
|
|
|
* Include/patchlevel.h: Release 1.5.2c1
|
|
|
|
* README: Release 1.5.2c1.
|
|
|
|
* Misc/NEWS: News for the 1.5.2c1 release.
|
|
|
|
* Lib/test/test_strftime.py:
|
|
On Windows, we suddenly find, strftime() may return "" for an
|
|
unsupported format string. (I guess this is because the logic for
|
|
deciding whether to reallocate the buffer or not has been improved.)
|
|
This caused the test code to crash on result[0]. Fix this by assuming
|
|
an empty result also means the format is not supported.
|
|
|
|
* Demo/tkinter/matt/window-creation-w-location.py:
|
|
This demo imported some private code from Matt. Make it cripple along.
|
|
|
|
* Lib/lib-tk/Tkinter.py:
|
|
Delete an accidentally checked-in feature that actually broke more
|
|
than was worth it: when deleting a canvas item, it would try to
|
|
automatically delete the bindings for that item. Since there's
|
|
nothing that says you can't reuse the tag and still have the bindings,
|
|
this is not correct. Also, it broke at least one demo
|
|
(Demo/tkinter/matt/rubber-band-box-demo-1.py).
|
|
|
|
* Python/thread_wince.h: Win/CE thread support by Mark Hammond.
|
|
|
|
Wed Apr 7 20:23:17 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Modules/zlibmodule.c:
|
|
Patch by Andrew Kuchling to unflush() (flush() for deflating).
|
|
Without this, if inflate() returned Z_BUF_ERROR asking for more output
|
|
space, we would report the error; now, we increase the buffer size and
|
|
try again, just as for Z_OK.
|
|
|
|
* Lib/test/test_gzip.py: Use binary mode for all gzip files we open.
|
|
|
|
* Tools/idle/ChangeLog: New change log.
|
|
|
|
* Tools/idle/README.txt, Tools/idle/NEWS.txt: New version.
|
|
|
|
* Python/pythonrun.c:
|
|
Alas, get rid of the Win specific hack to ask the user to press Return
|
|
before exiting when an error happened. This didn't work right when
|
|
Python is invoked from a daemon.
|
|
|
|
* Tools/idle/idlever.py: Version bump awaiting impending new release.
|
|
(Not much has changed :-( )
|
|
|
|
* Lib/lib-tk/Tkinter.py:
|
|
lower, tkraise/lift hide Misc.lower, Misc.tkraise/lift,
|
|
so the preferred name for them is tag_lower, tag_raise
|
|
(similar to tag_bind, and similar to the Text widget);
|
|
unfortunately can't delete the old ones yet (maybe in 1.6)
|
|
|
|
* Python/thread.c, Python/strtod.c, Python/mystrtoul.c, Python/import.c, Python/ceval.c:
|
|
Changes by Mark Hammond for Windows CE. Mostly of the form
|
|
#ifdef DONT_HAVE_header_H ... #endif around #include <header.h>.
|
|
|
|
* Python/bltinmodule.c:
|
|
Remove unused variable from complex_from_string() code.
|
|
|
|
* Include/patchlevel.h:
|
|
Add the possibility of a gamma release (release candidate).
|
|
Add '+' to string version number to indicate we're beyond b2 now.
|
|
|
|
* Modules/posixmodule.c: Add extern decl for fsync() for SunOS 4.x.
|
|
|
|
* Lib/smtplib.py: Changes by Per Cederquist and The Dragon.

"""
|
|
The application where Signum Support uses smtplib needs to be able to
|
|
report good error messages to the user when sending email fails. To
|
|
help in diagnosing problems it is useful to be able to report the
|
|
entire message sent by the server, not only the SMTP error code of the
|
|
offending command.
|
|
|
|
A lot of the functions in sendmail.py unfortunately discards the
|
|
message, leaving only the code. The enclosed patch fixes that
|
|
problem.
|
|
|
|
The enclosed patch also introduces a base class for exceptions that
|
|
include an SMTP error code and error message, and make the code and
|
|
message available on separate attributes, so that surrounding code can
|
|
deal with them in whatever way it sees fit. I've also added some
|
|
documentation to the exception classes.
|
|
|
|
The constructor will now raise an exception if it cannot connect to
|
|
the SMTP server.
|
|
|
|
The data() method will raise an SMTPDataError if it doesn't receive
|
|
the expected 354 code in the middle of the exchange.
|
|
|
|
According to section 5.2.10 of RFC 1123 a smtp client must accept "any
|
|
text, including no text at all" after the error code. If the response
|
|
of a HELO command contains no text self.helo_resp will be set to the
|
|
empty string (""). The patch fixes the test in the sendmail() method
|
|
so that helo_resp is tested against None; if it has the empty string
|
|
as value the sendmail() method would invoke the helo() method again.
|
|
|
|
The code no longer accepts a -1 reply from the ehlo() method in
|
|
sendmail().
|
|
|
|

and also:

"""
|
|
smtplib.py appends an extra blank line to the outgoing mail if the
|
|
`msg' argument to the sendmail method already contains a trailing
|
|
newline. This patch should fix the problem.
|
|
"""
|
|
|
|
The Dragon writes:
|
|
|
|
"""
|
|
Mostly I just re-added the SMTPRecipientsRefused exception
|
|
(the exeption object now has the appropriate info in it ) [Per had
|
|
removed this in his patch --GvR] and tweaked the behavior of the
|
|
sendmail method whence it throws the newly added SMTPHeloException (it
|
|
was closing the connection, which it shouldn't. whatever catches the
|
|
exception should do that. )
|
|
|
|
I pondered the change of the return values to tuples all around,
|
|
and after some thinking I decided that regularizing the return values was
|
|
too much of the Right Thing (tm) to not do.
|
|
|
|
My one concern is that code expecting an integer & getting a tuple
|
|
may fail silently.
|
|
|
|
(i.e. if it's doing :
|
|
|
|
x.somemethod() >= 400:
|
|
expecting an integer, the expression will always be true if it gets a
|
|
tuple instead. )
|
|
|
|
However, most smtplib code I've seen only really uses the
|
|
sendmail() method, so this wouldn't bother it. Usually code I've seen
|
|
that calls the other methods usually only calls helo() and ehlo() for
|
|
doing ESMTP, a feature which was not in the smtplib included with 1.5.1,
|
|
and thus I would think not much code uses it yet.

|
* Lib/test/test_ntpath.py:
|
|
Fix the tests now that splitdrive() no longer treats UNC paths special.
|
|
(Some tests converted to splitunc() tests.)
|
|
|
|
* Lib/ntpath.py:
|
|
Withdraw the UNC support from splitdrive(). Instead, a new function
|
|
splitunc() parses UNC paths. The contributor of the UNC parsing in
|
|
splitdrive() doesn't like it, but I haven't heard a good reason to
|
|
keep it, and it causes some problems. (I think there's a
|
|
philosophical problem -- to me, the split*() functions are purely
|
|
syntactical, and the fact that \\foo is not a valid path doesn't mean
|
|
that it shouldn't be considered an absolute path.)
|
|
|
|
Also (quite separately, but strangely related to the philosophical
|
|
issue above) fix abspath() so that if win32api exists, it doesn't fail
|
|
when the path doesn't actually exist -- if GetFullPathName() fails,
|
|
fall back on the old strategy (join with getcwd() if neccessary, and
|
|
then use normpath()).

"""
|

The GNU folks, in their infinite wisdom, have decided not to implement

altzone in libc6; this would not be horrible, except that timezone

(which is implemented) includes the current DST setting (i.e. timezone

|
for Central is 18000 in summer and 21600 in winter). So Python's

timezone and altzone variables aren't set correctly during DST.

Here's a patch relative to 1.5.2b2 that (a) makes timezone and altzone

show the "right" thing on Linux (by using the tm_gmtoff stuff

available in BSD, which is how the GLIBC manual claims things should

be done) and (b) should cope with the southern hemisphere. In pursuit

of (b), I also took the liberty of renaming the "summer" and "winter"

|
|
* Lib/test/test_gzip.py:
|
|
Added a simple test suite for gzip. It simply opens a temp file,
|
|
writes a chunk of compressed data, closes it, writes another chunk, and
|
|
reads the contents back to verify that they are the same.
|
|
|
|
* Lib/gzip.py:
|
|
Based on a suggestion from bruce@hams.com, make a trivial change to
|
|
allow using the 'a' flag as a mode for opening a GzipFile. gzip
|
|
files, surprisingly enough, can be concatenated and then decompressed;
|
|
the effect is to concatenate the two chunks of data.
|
|
|
|
If we support it on writing, it should also be supported on reading.
|
|
This *wasn't* trivial, and required rearranging the code in the
|
|
reading path, particularly the _read() method.
|
|
|
|
Raise IOError instead of RuntimeError in two cases, 'Not a gzipped file'
|
|
and 'Unknown compression method'

|
Add an .unused_data attribute to decompressor objects. If .unused_data

whatever follows the compressed stream.

Unfortunately his code breaks wcgui.py in a way that's not easy
|
|
to fix. I expect that this is a temporary situation --
|
|
eventually Sam's changes will be merged back in.
|

(The changes add a -t option to specify exceptions to the -x

|
* Modules/socketmodule.c:
|
|
Implement two suggestions by Jonathan Giddy: (1) in AIX, clear the
|
|
data struct before calling gethostby{name,addr}_r(); (2) ignore the
|
|
3/5/6 args determinations made by the configure script and switch on
|
|
platform identifiers instead:
|
|
|
|
AIX, OSF have 3 args
|
|
Sun, SGI have 5 args
|
|
Linux has 6 args
|
|
|
|
On all other platforms, undef HAVE_GETHOSTBYNAME_R altogether.
|
|
|
|
* Modules/socketmodule.c:
|
|
Vladimir Marangozov implements the AIX 3-arg gethostbyname_r code.
|
|
|
|
* Lib/mailbox.py:
|
|
Add readlines() to _Subfile class. Not clear who would need it, but

|
Chris Lawrence sent me a broken version; this one is a tad simpler and

more conforming to the standard.

|

Add code to test for all sorts of gethostbyname_r variants,

donated by David Arnold.
|
|
|

|
|
Add symbols for gethostbyname_r variants (sigh).
|
|
|
|
* Modules/socketmodule.c: Clean up pass for the previous patches.
|
|
|
|
- Use HAVE_GETHOSTBYNAME_R_6_ARG instead of testing for Linux and
|
|
glibc2.
|
|
|
|
- If gethostbyname takes 3 args, undefine HAVE_GETHOSTBYNAME_R --
|
|
don't know what code should be used.
|
|
|
|
- New symbol USE_GETHOSTBYNAME_LOCK defined iff the lock should be used.
|
|
|
|
- Modify the gethostbyaddr() code to also hold on to the lock until
|
|
after it is safe to release, overlapping with the Python lock.
|
|
|
|
(Note: I think that it could in theory be possible that Python code
|
|
executed while gethostbyname_lock is held could attempt to reacquire
|
|
the lock -- e.g. in a signal handler or destructor. I will simply say
|
|
"don't do that then.")

|
|
|
* Modules/socketmodule.c: Jonathan Giddy writes:
|
|
|
|
Here's a patch to fix the race condition, which wasn't fixed by Rob's
|
|
patch. It holds the gethostbyname lock until the results are copied out,
|
|
which means that this lock and the Python global lock are held at the same
|
|
time. This shouldn't be a problem as long as the gethostbyname lock is
|
|
always acquired when the global lock is not held.

* Modules/zlibmodule.c:
|
|
Fixed the flush() method of compression objects; the test for
|
|
the end of loop was incorrect, and failed when the flushmode != Z_FINISH.
|
|
Logic cleaned up and commented.
|
|
|
|
* Lib/test/test_zlib.py:

Added simple test for the flush() method of compression objects, trying the

different flush values Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH.

|
|
Fix a problem with Vladimir's PyFloat_Fini code: clear the free list; if

a block cannot be freed, add its free items back to the free list.
|
|
This is necessary to avoid leaking when Python is reinitialized later.
|

* Objects/intobject.c:
|
|
Fix a problem with Vladimir's PyInt_Fini code: clear the free list; if
|
|
a block cannot be freed, add its free items back to the free list, and
|
|
add its valid ints back to the small_ints array if they are in range.
|
|
This is necessary to avoid leaking when Python is reinitialized later.
|
|
|
|
* Lib/types.py:
|
|
Added BufferType, the type returned by the new builtin buffer(). Greg Stein.
|
|
|
|
* Python/bltinmodule.c:
|
|
New builtin buffer() creates a derived read-only buffer from any
|
|
object that supports the buffer interface (e.g. strings, arrays).
|
|
|
|
* Objects/bufferobject.c:
|
|
Added check for negative offset for PyBuffer_FromObject and check for
|
|
negative size for PyBuffer_FromMemory. Greg Stein.

* Lib/urlparse.py: Sjoerd Mullender writes:
|
|
|
|
If a filename on Windows starts with \\, it is converted to a URL
|
|
which starts with ////. If this URL is passed to urlparse.urlparse
|
|
you get a path that starts with // (and an empty netloc). If you pass
|
|
the result back to urlparse.urlunparse, you get a URL that starts with
|
|
//, which is parsed differently by urlparse.urlparse. The fix is to
|
|
add the (empty) netloc with accompanying slashes if the path in

urlunparse starts with //. Do this for all schemes that use a netloc.

* Lib/nturl2path.py: Sjoerd Mullender writes:

|
|
|
|
* Lib/urlparse.py:
|
|
Delete non-standard-conforming code in urljoin() that would use the
|
|
netloc from the base url as the default netloc for the resulting url
|
|
even if the schemes differ.
|
|
|
|
Once upon a time, when the web was wild, this was a valuable hack
|
|
because some people had a URL referencing an ftp server colocated with
|
|
an http server without having the host in the ftp URL (so they could
|
|
replicate it or change the hostname easily).
|
|
|
|
More recently, after the file: scheme got added back to the list of
|
|
schemes that accept a netloc, it turns out that this caused weirdness
|
|
when joining an http: URL with a file: URL -- the resulting file: URL
|
|
would always inherit the host from the http: URL because the file:
|
|
scheme supports a netloc but in practice never has one.
|
|
|
|
There are two reasons to get rid of the old, once-valuable hack,
|
|
instead of removing the file: scheme from the uses_netloc list. One,
|
|
the RFC says that file: uses the netloc syntax, and does not endorse
|
|
the old hack. Two, neither netscape 4.5 nor IE 4.0 support the old
|
|
hack.

|
An attempt to execute grid_slaves with arguments (0,0) results in

|
*all* of the slaves being returned, not just the slave associated with
|
|
row 0, column 0. This is because the test for arguments in the method
|
|
does not test to see if row (and column) does not equal None, but
|
|
rather just whether is evaluates to non-false. A value of 0 fails
|
|
this test.

|
|
extra argument if data is None.
|
|
|
|
* Demo/embed/demo.c:
|
|
Call Py_SetProgramName() instead of redefining getprogramname(),
|
|
reflecting changes in the runtime around 1.5 or earlier.
|
|
|
|
* Python/ceval.c:
|
|
Always test for an error return (usually NULL or -1) without setting
|
|
an exception.
|
|
|
|
* Modules/timemodule.c: Patch by Chris Herborth for BeOS code.
|
|
He writes:
|
|
|
|
I had an off-by-1000 error in floatsleep(),
|
|
and the problem with time.clock() is that it's not implemented properly
|
|
on QNX... ANSI says it's supposed to return _CPU_ time used by the
|
|
process, but on QNX it returns the amount of real time used... so I was
|
|
confused.
|
|
|
|
* Tools/bgen/bgen/macsupport.py: Small change by Jack Jansen.
|
|
Test for self.returntype behaving like OSErr rather than being it.

|
Thu Feb 25 16:14:58 1999 Jeremy Hylton <jhylton@eric.cnri.reston.va.us>
|
|
|
|
* Lib/urllib.py:
|
|
http_error had the 'data is None' test backwards. don't call with the
|
|
extra argument if data is None.
|
|
|
|
* Lib/urllib.py: change indentation from 8 spaces to 4 spaces
|
|
|
|
* Lib/urllib.py: pleasing the tabnanny

Thu Feb 25 14:26:02 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
|
|
|
|
* Lib/colorsys.py:
|
|
Oops, one more "x, y, z" to convert...
|
|
|
|
* Lib/colorsys.py:
|
|
Adjusted comment at the top to be less confusing, following Fredrik
|
|
Lundh's example.
|
|
|
|
Converted comment to docstring.
|
|
|
|
Wed Feb 24 18:49:15 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
|
|
|
|
* Lib/toaiff.py:
|
|
Use sndhdr instead of the obsolete whatsound module.
|
|
|
|
Wed Feb 24 18:42:38 1999 Jeremy Hylton <jhylton@eric.cnri.reston.va.us>
|
|
|
|
* Lib/urllib.py:
|
|
When performing a POST request, i.e. when the second argument to
|
|
urlopen is used to specify form data, make sure the second argument is
|
|
threaded through all of the http_error_NNN calls. This allows error
|
|
handlers like the redirect and authorization handlers to properly
|
|
re-start the connection.
|
|
|
|
Wed Feb 24 16:25:17 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Lib/mhlib.py: Patch by Lars Wirzenius:
|
|
|
|
o the initial comment is wrong: creating messages is already
|
|
implemented
|
|
|
|
o Message.getbodytext: if the mail or it's part contains an
|
|
empty content-transfer-encoding header, the code used to
|
|
break; the change below treats an empty encoding value the same
|
|
as the other types that do not need decoding
|
|
|
|
o SubMessage.getbodytext was missing the decode argument; the
|
|
change below adds it; I also made it unconditionally return
|
|
the raw text if decoding was not desired, because my own
|
|
routines needed that (and it was easier than rewriting my
|
|
own routines ;-)
|
|
|
|
Wed Feb 24 00:35:43 1999 Barry Warsaw <bwarsaw@eric.cnri.reston.va.us>
|
|
|
|
* Python/bltinmodule.c (initerrors):
|
|
Make sure that the exception tuples ("base-classes" when
|
|
string-based exceptions are used) reflect the real class hierarchy,
|
|
i.e. that SystemExit derives from Exception not StandardError.
|
|
|
|
* Lib/exceptions.py:
|
|
Document the correct class hierarchy for SystemExit. It is not an
|
|
error and so it derives from Exception and not SystemError. The
|
|
docstring was incorrect but the implementation was fine.
|
|
|
|
Tue Feb 23 23:07:51 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Lib/shutil.py:
|
|
Add import sys, needed by reference to sys.exc_info() in rmtree().
|
|
Discovered by Mitch Chapman.
|
|
|
|
* config.h.in:
|
|
Now that we don't have AC_CHECK_LIB(m, pow), the HAVE_LIBM symbol
|
|
disappears. It wasn't used anywhere anyway...
|
|
|
|
* Modules/arraymodule.c:
|
|
Carefully check for overflow when allocating the memory for fromfile
|
|
-- someone tried to pass in sys.maxint and got bitten by the bogus
|
|
calculations.
|
|
|
|
* configure.in:
|
|
Get rid of AC_CHECK_LIB(m, pow) since this is taken care of later with
|
|
LIBM (from --with-libm=...); this actually broke the customizability
|
|
offered by the latter option. Thanks go to Clay Spence for reporting
|
|
this.
|
|
|
|
* Lib/test/test_dl.py:
|
|
1. Print the error message (carefully) when a dl.open() fails in verbose mode.
|
|
2. When no test case worked, raise ImportError instead of failing.
|
|
|
|
* Python/bltinmodule.c:
|
|
Patch by Tim Peters to improve the range checks for range() and
|
|
xrange(), especially for platforms where int and long are different
|
|
sizes (so sys.maxint isn't actually the theoretical limit for the
|
|
length of a list, but the largest C int is -- sys.maxint is the
|
|
largest Python int, which is actually a C long).
|
|
|
|
* Makefile.in:
|
|
1. Augment the DG/UX rule so it doesn't break the BeOS build.
|
|
2. Add $(EXE) to various occurrences of python so it will work on
|
|
Cygwin with egcs (after setting EXE=.exe). These patches by
|
|
Norman Vine.
|
|
|
|
* Lib/posixfile.py:
|
|
According to Jeffrey Honig, bsd/os 2.0 - 4.0 should be added to the
|
|
list (of bsd variants that have a different lock structure).
|
|
|
|
* Lib/test/test_fcntl.py:
|
|
According to Jeffrey Honig, bsd/os 4.0 should be added to the list.
|
|
|
|
* Modules/timemodule.c:
|
|
Patch by Tadayoshi Funaba (with some changes) to be smarter about
|
|
guessing what happened when strftime() returns 0. Is it buffer
|
|
overflow or was the result simply 0 bytes long? (This happens for an
|
|
empty format string, or when the format string is a single %Z and the
|
|
timezone is unknown.) if the buffer is at least 256 times as long as
|
|
the format, assume the latter.
|
|
|
|
Mon Feb 22 19:01:42 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Lib/urllib.py:
|
|
As Des Barry points out, we need to call pathname2url(file) in two
|
|
calls to addinfourl() in open_file().
|
|
|
|
* Modules/Setup.in: Document *static* -- in two places!
|
|
|
|
* Modules/timemodule.c:
|
|
We don't support leap seconds, so the seconds field of a time 9-tuple
|
|
should be in the range [0-59]. Noted by Tadayoshi Funaba.
|
|
|
|
* Modules/stropmodule.c:
|
|
In atoi(), don't use isxdigit() to test whether the last character
|
|
converted was a "digit" -- use isalnum(). This test is there only to
|
|
guard against "+" or "-" being interpreted as a valid int literal.
|
|
Reported by Takahiro Nakayama.
|
|
|
|
* Lib/os.py:
|
|
As Finn Bock points out, _P_WAIT etc. don't have a leading underscore
|
|
so they don't need to be treated specially here.
|
|
|
|
Mon Feb 22 15:38:58 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
|
|
|
|
* Misc/NEWS:
|
|
Typo: "apparentlt" --> "apparently"
|
|
|
|
Mon Feb 22 15:38:46 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
|
|
|
|
* Lib/urlparse.py: Steve Clift pointed out that 'file' allows a netloc.
|
|
|
|
* Modules/posixmodule.c:
|
|
The docstring for ttyname(..) claims a second "mode" argument. The
|
|
actual code does not allow such an argument. (Finn Bock.)
|
|
|
|
* Lib/lib-old/poly.py:
|
|
Dang. Even though this is obsolete code, somebody found a bug, and I
|
|
fix it. Oh well.
|
|
|
|
Thu Feb 18 20:51:50 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
|
|
|
|
* Lib/pyclbr.py:
|
|
Bow to font-lock at the end of the docstring, since it throws stuff
|
|
off.
|
|
|
|
Make sure the path paramter to readmodule() is a list before adding it
|
|
with sys.path, or the addition could fail.

|
|
|
======================================================================
|
|
|
|
|
|
From 1.5.2b1 to 1.5.2b2
|
|
=======================
|
|
|
|
General
|
|
-------
|
|
|
|
- Many memory leaks fixed.
|
|
|
|
- Many small bugs fixed.
|
|
|
|
- Command line option -OO (or -O -O) suppresses inclusion of doc
|
|
strings in resulting bytecode.
|
|
|
|
Windows-specific changes
|
|
------------------------
|
|
|
|
- New built-in module winsound provides an interface to the Win32
|
|
PlaySound() call.
|
|
|
|
- Re-enable the audioop module in the config.c file.
|
|
|
|
- On Windows, support spawnv() and associated P_* symbols.
|
|
|
|
- Fixed the conversion of times() return values on Windows.
|
|
|
|
- Removed freeze from the installer -- it doesn't work without the
|
|
source tree. (See FAQ 8.11.)
|
|
|
|
- On Windows 95/98, the Tkinter module now is smart enough to find
|
|
Tcl/Tk even when the PATH environment variable hasn't been set -- when
|
|
the import of _tkinter fails, it searches in a standard locations,
|
|
patches os.environ["PATH"], and tries again. When it still fails, a
|
|
clearer error message is produced. This should avoid most
|
|
installation problems with Tkinter use (e.g. in IDLE).
|
|
|
|
- The -i option doesn't make any calls to set[v]buf() for stdin --
|
|
this apparently screwed up _kbhit() and the _tkinter main loop.
|
|
|
|
- The ntpath module (and hence, os.path on Windows) now parses out UNC
|
|
paths (e.g. \\host\mountpoint\dir\file) as "drive letters", so that
|
|
splitdrive() will \\host\mountpoint as the drive and \dir\file as the
|
|
path. ** EXPERIMENTAL **
|
|
|
|
- Added a hack to the exit code so that if (1) the exit status is
|
|
nonzero and (2) we think we have our own DOS box (i.e. we're not
|
|
started from a command line shell), we print a message and wait for
|
|
the user to hit a key before the DOS box is closed.
|
|
|
|
- Updated the installer to WISE 5.0g. Added a dialog warning about
|
|
the imminent Tcl installation. Added a dialog to specify the program
|
|
group name in the start menu. Upgraded the Tcl installer to Tcl
|
|
8.0.4.
|
|
|
|
Changes to intrinsics
|
|
---------------------
|
|
|
|
- The repr() or str() of a module object now shows the __file__
|
|
attribute (i.e., the file which it was loaded), or the string
|
|
"(built-in)" if there is no __file__ attribute.
|
|
|
|
- The range() function now avoids overflow during its calculations (if
|
|
at all possible).
|
|
|
|
- New info string sys.hexversion, which is an integer encoding the
|
|
version in hexadecimal. In other words, hex(sys.hexversion) ==
|
|
0x010502b2 for Python 1.5.2b2.
|
|
|
|
New or improved ports
|
|
---------------------
|
|
|
|
- Support for Nextstep descendants (future Mac systems).
|
|
|
|
- Improved BeOS support.
|
|
|
|
- Support dynamic loading of shared libraries on NetBSD platforms that
|
|
use ELF (i.e., MIPS and Alpha systems).
|
|
|
|
Configuration/build changes
|
|
---------------------------
|
|
|
|
- The Lib/test directory is no longer included in the default module
|
|
search path (sys.path) -- "test" has been a package ever since 1.5.
|
|
|
|
- Now using autoconf 2.13.
|
|
|
|
New library modules
|
|
-------------------
|
|
|
|
- New library modules asyncore and asynchat: these form Sam Rushing's
|
|
famous asynchronous socket library. Sam has gracefully allowed me to
|
|
incorporate these in the standard Python library.
|
|
|
|
- New module statvfs contains indexing constants for [f]statvfs()
|
|
return tuple.
|
|
|
|
Changes to the library
|
|
----------------------
|
|
|
|
- The wave module (platform-independent support for Windows sound
|
|
files) has been fixed to actually make it work.
|
|
|
|
- The sunau module (platform-independent support for Sun/NeXT sound
|
|
files) has been fixed to work across platforms. Also, a weird
|
|
encoding bug in the header of the audio test data file has been
|
|
corrected.
|
|
|
|
- Fix a bug in the urllib module that occasionally tripped up
|
|
webchecker and other ftp retrieves.
|
|
|
|
- ConfigParser's get() method now accepts an optional keyword argument
|
|
(vars) that is substituted on top of the defaults that were setup in
|
|
__init__. You can now also have recusive references in your
|
|
configuration file.
|
|
|
|
- Some improvements to the Queue module, including a put_nowait()
|
|
module and an optional "block" second argument, to get() and put(),
|
|
defaulting to 1.
|
|
|
|
- The updated xmllib module is once again compatible with the version
|
|
present in Python 1.5.1 (this was accidentally broken in 1.5.2b1).
|
|
|
|
- The bdb module (base class for the debugger) now supports
|
|
canonicalizing pathnames used in breakpoints. The derived class must
|
|
override the new canonical() method for this to work. Also changed
|
|
clear_break() to the backwards compatible old signature, and added
|
|
clear_bpbynumber() for the new functionality.
|
|
|
|
- In sgmllib (and hence htmllib), recognize attributes even if they
|
|
don't have space in front of them. I.e. '<a
|
|
name="foo"href="bar.html">' will now have two attributes recognized.
|
|
|
|
- In the debugger (pdb), change clear syntax to support three
|
|
alternatives: clear; clear file:line; clear bpno bpno ...
|
|
|
|
- The os.path module now pretends to be a submodule within the os
|
|
"package", so you can do things like "from os.path import exists".
|
|
|
|
- The standard exceptions now have doc strings.
|
|
|
|
- In the smtplib module, exceptions are now classes. Also avoid
|
|
inserting a non-standard space after "TO" in rcpt() command.
|
|
|
|
- The rfc822 module's getaddrlist() method now uses all occurrences of
|
|
the specified header instead of just the first. Some other bugfixes
|
|
too (to handle more weird addresses found in a very large test set,
|
|
and to avoid crashes on certain invalid dates), and a small test
|
|
module has been added.
|
|
|
|
- Fixed bug in urlparse in the common-case code for HTTP URLs; it
|
|
would lose the query, fragment, and/or parameter information.
|
|
|
|
- The sndhdr module no longer supports whatraw() -- it depended on a
|
|
rare extenral program.
|
|
|
|
- The UserList module/class now supports the extend() method, like
|
|
real list objects.
|
|
|
|
- The uu module now deals better with trailing garbage generated by
|
|
some broke uuencoders.
|
|
|
|
- The telnet module now has an my_interact() method which uses threads
|
|
instead of select. The interact() method uses this by default on
|
|
Windows (where the single-threaded version doesn't work).
|
|
|
|
- Add a class to mailbox.py for dealing with qmail directory
|
|
mailboxes. The test code was extended to notice these being used as
|
|
well.
|
|
|
|
Changes to extension modules
|
|
----------------------------
|
|
|
|
- Support for the [f]statvfs() system call, where it exists.
|
|
|
|
- Fixed some bugs in cPickle where bad input could cause it to dump
|
|
core.
|
|
|
|
- Fixed cStringIO to make the writelines() function actually work.
|
|
|
|
- Added strop.expandtabs() so string.expandtabs() is now much faster.
|
|
|
|
- Added fsync() and fdatasync(), if they appear to exist.
|
|
|
|
- Support for "long files" (64-bit seek pointers).
|
|
|
|
- Fixed a bug in the zlib module's flush() function.
|
|
|
|
- Added access() system call. It returns 1 if access granted, 0 if
|
|
not.
|
|
|
|
- The curses module implements an optional nlines argument to
|
|
w.scroll(). (It then calls wscrl(win, nlines) instead of scoll(win).)
|
|
|
|
Changes to tools
|
|
----------------
|
|
|
|
- Some changes to IDLE; see Tools/idle/NEWS.txt.
|
|
|
|
- Latest version of Misc/python-mode.el included.
|
|
|
|
Changes to Tkinter
|
|
------------------
|
|
|
|
- Avoid tracebacks when an image is deleted after its root has been
|
|
destroyed.
|
|
|
|
Changes to the Python/C API
|
|
---------------------------
|
|
|
|
- When parentheses are used in a PyArg_Parse[Tuple]() call, any
|
|
sequence is now accepted, instead of requiring a tuple. This is in
|
|
line with the general trend towards accepting arbitrary sequences.
|
|
|
|
- Added PyModule_GetFilename().
|
|
|
|
- In PyNumber_Power(), remove unneeded and even harmful test for float
|
|
to the negative power (which is already and better done in
|
|
floatobject.c).
|
|
|
|
- New version identification symbols; read patchlevel.h for info. The
|
|
version numbers are now exported by Python.h.
|
|
|
|
- Rolled back the API version change -- it's back to 1007!
|
|
|
|
- The frozenmain.c function calls PyInitFrozenExtensions().
|
|
|
|
- Added 'N' format character to Py_BuildValue -- like 'O' but doesn't
|
|
INCREF.
|
|
|
|
|
|
======================================================================
|
|
|
|
|
|
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
|
|
-------------------
|
|
|
|
- shlex.py by Eric Raymond provides a lexical analyzer class for
|
|
simple shell-like syntaxes.
|
|
|
|
- netrc.py by Eric Raymond provides a parser for .netrc files. (The
|
|
undocumented Netrc class in ftplib.py is now obsolete.)
|
|
|
|
- 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

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.
|
|
Patch by Sjoerd Mullender. Note that if you subclass one of the
|
|
URLopener classes, and you have copied code from the old urllib.py,
|
|
your subclass may stop working. A long-term solution is to provide
|
|
more methods so that you don't have to copy code.
|
|
|
|
- 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.
|
|
