+From 1.5.2b2 to 1.5.2c1
+=======================
+
+Thu Apr 8 17:23:11 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * 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.
+
+ Per writes:
+
+ """
+ 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().
+
+ [Text about removing SMTPRecipientsRefused deleted --GvR]
+ """
+
+ 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()).
+
+ * configure.in, configure, config.h.in, acconfig.h:
+ For BeOS PowerPC. Chris Herborth.
+
+Mon Apr 5 21:54:14 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Modules/timemodule.c:
+ Jonathan Giddy notes, and Chris Lawrence agrees, that some comments on
+ #else/#endif are wrong, and that #if HAVE_TM_ZONE should be #ifdef.
+
+ * Misc/ACKS:
+ Bunch of new contributors, including 9 who contributed to the Docs,
+ reported by Fred.
+
+Mon Apr 5 18:37:59 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
+
+ * Lib/gzip.py:
+ Oops, missed mode parameter to open().
+
+ * Lib/gzip.py:
+ Made the default mode 'rb' instead of 'r', for better cross-platform
+ support. (Based on comment on the documentation by Bernhard Reiter
+ <bernhard@csd.uwm.edu>).
+
+Fri Apr 2 22:18:25 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Tools/scripts/dutree.py:
+ For reasons I dare not explain, this script should always execute
+ main() when imported (in other words, it is not usable as a module).
+
+Thu Apr 1 15:32:30 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/test_cpickle.py: Jonathan Giddy write:
+
+ In test_cpickle.py, the module os got imported, but the line to remove
+ the temp file has gone missing.
+
+Tue Mar 30 20:17:31 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/BaseHTTPServer.py: Per Cederqvist writes:
+
+ If you send something like "PUT / HTTP/1.0" to something derived from
+ BaseHTTPServer that doesn't define do_PUT, you will get a response
+ that begins like this:
+
+ HTTP/1.0 501 Unsupported method ('do_PUT')
+ Server: SimpleHTTP/0.3 Python/1.5
+ Date: Tue, 30 Mar 1999 18:53:53 GMT
+
+ The server should complain about 'PUT' instead of 'do_PUT'. This
+ patch should fix the problem.
+
+Mon Mar 29 20:33:21 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/smtplib.py: Patch by Per Cederqvist, who writes:
+
+ """
+ - It needlessly used the makefile() method for each response that is
+ read from the SMTP server.
+
+ - If the remote SMTP server closes the connection unexpectedly the

+
+ - The code now checks that all lines in a multiline response actually

+
+ The Dragon approves.
+
+Mon Mar 29 20:25:40 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
+
+ * Lib/compileall.py:
+ When run as a script, report failures in the exit code as well.
+ Patch largely based on changes by Andrew Dalke, as discussed in the
+ distutils-sig.
+
+Mon Mar 29 20:23:41 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/urllib.py:
+ Hack so that if a 302 or 301 redirect contains a relative URL, the

+
+ * Modules/cPickle.c:
+ Protection against picling to/from closed (real) file.
+ The problem was reported by Moshe Zadka.

+ Test protection against picling to/from closed (real) file.
+
+ * Modules/timemodule.c: Chris Lawrence writes:

+ 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

+
+ * Lib/test/output/test_gzip:
+ Jonathan Giddy discovered this file was missing.

+ * Modules/shamodule.c:
+ Avoid warnings from AIX compiler. Reported by Vladimir (AIX is my

+ * Tools/scripts/dutree.py:
+ During display, if EPIPE is raised, it's probably because a pager was

+
+Fri Mar 26 16:20:45 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/output/test_userlist, Lib/test/test_userlist.py:
+ Test suite for UserList.

+ Reformatted with 4-space indent.
+
+Fri Mar 26 16:11:40 1999 Barry Warsaw <bwarsaw@eric.cnri.reston.va.us>
+
+ * Tools/pynche/PyncheWidget.py:
+ Helpwin.__init__(): The text widget should get focus.
+
+ * Tools/pynche/pyColorChooser.py:

+Fri Mar 26 15:32:05 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/output/test_userdict, Lib/test/test_userdict.py:
+ Test suite for UserDict
+
+ * Lib/UserDict.py: Improved a bunch of things.
+ The constructor now takes an optional dictionary.
+ Use isinstance() where appropriate.
+
+Thu Mar 25 22:38:49 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/output/test_pickle, Lib/test/output/test_cpickle, Lib/test/test_pickle.py, Lib/test/test_cpickle.py:
+ Basic regr tests for pickle/cPickle
+
+ * Lib/pickle.py:
+ Don't use "exec" in find_class(). It's slow, unnecessary, and (as AMK
+ points out) it doesn't work in JPython Applets.
+
+Thu Mar 25 21:50:27 1999 Andrew Kuchling <akuchlin@eric.cnri.reston.va.us>
+
+ * 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'
+
+Thu Mar 25 21:25:01 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/test_b1.py:
+ Add tests for float() and complex() with string args (Nick/Stephanie
+ Lockwood).
+
+Thu Mar 25 21:21:08 1999 Andrew Kuchling <akuchlin@eric.cnri.reston.va.us>
+
+ * Modules/zlibmodule.c:
+ Add an .unused_data attribute to decompressor objects. If .unused_data
+ is not an empty string, this means that you have arrived at the
+ end of the stream of compressed data, and the contents of .unused_data are
+ whatever follows the compressed stream.
+
+Thu Mar 25 21:16:07 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Python/bltinmodule.c:
+ Patch by Nick and Stephanie Lockwood to implement complex() with a string
+ argument. This closes TODO item 2.19.
+
+Wed Mar 24 19:09:00 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Tools/webchecker/wcnew.py: Added Samuel Bayer's new webchecker.
+ 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
+ option, and explicit checking for #foo style fragment ids.)
+
+ * Objects/dictobject.c:
+ Vladimir Marangozov contributed updated comments.
+
+ * Objects/bufferobject.c: Folded long lines.
+
+ * Lib/test/output/test_sha, Lib/test/test_sha.py:
+ Added Jeremy's test code for the sha module.
+
+ * Modules/shamodule.c, Modules/Setup.in:
+ Added Greg Stein and Andrew Kuchling's sha module.
+ Fix comments about zlib version and URL.
+
+ * Lib/test/test_bsddb.py: Remove the temp file when we're done.
+
+ * Include/pythread.h: Conform to standard boilerplate.
+
+ * configure.in, configure, BeOS/linkmodule, BeOS/ar-fake:
+ Chris Herborth: the new compiler in R4.1 needs some new options to work...
+
+ * 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.
+
+Tue Mar 23 23:05:34 1999 Jeremy Hylton <jhylton@eric.cnri.reston.va.us>
+
+ * Lib/gzip.py: use struct instead of bit-manipulate in Python
+
+Tue Mar 23 19:00:55 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Modules/Makefile.pre.in:
+ Add $(EXE) to various occurrences of python so it will work on Cygwin
+ with egcs (after setting EXE=.exe). Patch by Norman Vine.
+
+ * configure, configure.in:
+ Ack! It never defined HAVE_GETHOSTBYNAME_R so that code was never tested!
+
+Mon Mar 22 22:25:39 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Include/thread.h:
+ Adding thread.h -- unused but for b/w compatibility.
+ As requested by Bill Janssen.
+
+ * configure.in, configure:
+ Add code to test for all sorts of gethostbyname_r variants,
+ donated by David Arnold.
+
+ * config.h.in, acconfig.h:
+ 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.
+
+Mon Mar 22 19:25:30 1999 Andrew Kuchling <akuchlin@eric.cnri.reston.va.us>
+
+ * 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.
+
+Mon Mar 22 15:28:08 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/shlex.py:
+ Bug reported by Tobias Thelen: missing "self." in assignment target.
+
+Fri Mar 19 21:50:11 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Modules/arraymodule.c:
+ Use an unsigned cast to avoid a warning in VC++.
+
+ * Lib/dospath.py, Lib/ntpath.py:
+ New code for split() by Tim Peters, behaves more like posixpath.split().
+
+ * Objects/floatobject.c:
+ 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:
+
+ Pathnames of files on other hosts in the same domain

+Wed Mar 17 22:30:10 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * 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.
+
+ * Include/ceval.h, Include/abstract.h:
+ Add DLL level b/w compat for PySequence_In and PyEval_CallObject

+ * Lib/lib-tk/Tkinter.py: Bug reported by Jim Robinson:
+
+ 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.
+
+Tue Mar 16 14:17:48 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
+
+ * Modules/cmathmodule.c:
+ Docstring fix: acosh() returns the hyperbolic arccosine, not the
+ hyperbolic cosine. Problem report via David Ascher by one of his
+ students.
+
+Mon Mar 15 21:40:59 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * configure.in:
+ Should test for gethost*by*name_r, not for gethostname_r (which
+ doesn't exist and doesn't make sense).
+
+ * Modules/socketmodule.c:
+ Patch by Rob Riggs for Linux -- glibc2 has a different argument
+ converntion for gethostbyname_r() etc. than Solaris!
+
+ * Python/thread_pthread.h: Rob Riggs wrote:
+
+ """
+ Spec says that on success pthread_create returns 0. It does not say
+ that an error code will be < 0. Linux glibc2 pthread_create() returns
+ ENOMEM (12) when one exceed process limits. (It looks like it should
+ return EAGAIN, but that's another story.)
+
+ For reference, see:
+ http://www.opengroup.org/onlinepubs/7908799/xsh/pthread_create.html
+ """
+
+ [I have a feeling that similar bugs were fixed before; perhaps someone
+ could check that all error checks no check for != 0?]
+
+ * Tools/bgen/bgen/bgenObjectDefinition.py:
+ New mixin class that defines cmp and hash that use
+ the ob_itself pointer. This allows (when using the mixin)
+ different Python objects pointing to the same C object and
+ behaving well as dictionary keys.
+
+ Or so sez Jack Jansen...
+
+ * Lib/urllib.py: Yet another patch by Sjoerd Mullender:
+
+ Don't convert URLs to URLs using pathname2url.
+
+Fri Mar 12 22:15:43 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/cmd.py: Patch by Michael Scharf. He writes:
+
+ The module cmd requires for each do_xxx command a help_xxx
+ function. I think this is a little old fashioned.
+
+ Here is a patch: use the docstring as help if no help_xxx
+ function can be found.
+
+ [I'm tempted to rip out all the help_* functions from pdb, but I'll
+ resist it. Any takers? --Guido]
+
+ * Tools/freeze/freeze.py: Bug submitted by Wayne Knowles, who writes:
+
+ Under Windows, python freeze.py -o hello hello.py
+ creates all the correct files in the hello subdirectory, but the
+ Makefile has the directory prefix in it for frozen_extensions.c
+ nmake fails because it tries to locate hello/frozen_extensions.c
+
+ (His fix adds a call to os.path.basename() in the appropriate place.)
+
+ * Objects/floatobject.c, Objects/intobject.c:
+ Vladimir has restructured his code somewhat so that the blocks are now
+ represented by an explicit structure. (There are still too many casts
+ in the code, but that may be unavoidable.)
+
+ Also added code so that with -vv it is very chatty about what it does.
+
+ * Demo/zlib/zlibdemo.py, Demo/zlib/minigzip.py:
+ Change #! line to modern usage; also chmod +x
+
+ * Demo/pdist/rrcs, Demo/pdist/rcvs, Demo/pdist/rcsbump:
+ Change #! line to modern usage
+
+ * Lib/nturl2path.py, Lib/urllib.py: From: Sjoerd Mullender
+
+ The filename to URL conversion didn't properly quote special
+ characters.
+ The URL to filename didn't properly unquote special chatacters.
+
+ * Objects/floatobject.c:
+ OK, try again. Vladimir gave me a fix for the alignment bus error,
+ so here's his patch again. This time it works (at least on Solaris,
+ Linux and Irix).
+
+Thu Mar 11 23:21:23 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Tools/idle/PathBrowser.py:
+ Don't crash when sys.path contains an empty string.
+
+ * Tools/idle/PathBrowser.py:
+ - Don't crash in the case where a superclass is a string instead of a
+ pyclbr.Class object; this can happen when the superclass is
+ unrecognizable (to pyclbr), e.g. when module renaming is used.
+
+ - Show a watch cursor when calling pyclbr (since it may take a while
+ recursively parsing imported modules!).
+
+Thu Mar 11 16:04:04 1999 Fred Drake <fdrake@eric.cnri.reston.va.us>
+
+ * Lib/mimetypes.py:
+ Added .rdf and .xsl as application/xml types. (.rdf is for the
+ Resource Description Framework, a metadata encoding, and .xsl is for
+ the Extensible Stylesheet Language.)
+
+Thu Mar 11 13:26:23 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/test/output/test_popen2, Lib/test/test_popen2.py:
+ Test for popen2 module, by Chris Tismer.
+
+ * Objects/floatobject.c:
+ Alas, Vladimir's patch caused a bus error (probably double
+ alignment?), and I didn't test it. Withdrawing it for now.
+
+Wed Mar 10 22:55:47 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Objects/floatobject.c:
+ Patch by Vladimir Marangoz to allow freeing of the allocated blocks of
+ floats on finalization.
+
+ * Objects/intobject.c:
+ Patch by Vladimir Marangoz to allow freeing of the allocated blocks of
+ integers on finalization.
+
+ * Tools/idle/EditorWindow.py, Tools/idle/Bindings.py:
+ Add PathBrowser to File module
+
+ * Tools/idle/PathBrowser.py:
+ "Path browser" - 4 scrolled lists displaying:
+ directories on sys.path
+ modules in selected directory
+ classes in selected module
+ methods of selected class
+
+ Sinlge clicking in a directory, module or class item updates the next
+ column with info about the selected item. Double clicking in a
+ module, class or method item opens the file (and selects the clicked
+ item if it is a class or method).
+
+ I guess eventually I should be using a tree widget for this, but the
+ ones I've seen don't work well enough, so for now I use the old
+ Smalltalk or NeXT style multi-column hierarchical browser.
+
+ * Tools/idle/MultiScrolledLists.py:
+ New utility: multiple scrolled lists in parallel
+
+ * Tools/idle/ScrolledList.py: - White background.
+ - Display "(None)" (or text of your choosing) when empty.
+ - Don't set the focus.
+
+Tue Mar 9 19:31:21 1999 Guido van Rossum <guido@eric.cnri.reston.va.us>
+
+ * Lib/urllib.py:
+ open_http also had the 'data is None' test backwards. don't call with the
+ 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.
+
