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 + (\\host\path\to\file) are not translated correctly to URLs and back. + The URL should be something like file:////host/path/to/file. + Note that a combination of drive letter and remote host is not + possible. + +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 + +Tue Mar 16 21:54:50 1999 Guido van Rossum <guido@eric.cnri.reston.va.us> + + * 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.

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. + + +====================================================================== + + +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 + = pynche: The PYthonically Natural Color and Hue Editor + = world: Print mappings between country names and DNS country codes + +New demos +--------- + +- Demo/scripts/beer.py prints the lyrics to an arithmetic drinking +song. + +- Demo/tkinter/guido/optionmenu.py shows how to do an option menu in +Tkinter. (By Fredrik Lundh -- not by me!) + +Changes to the library +---------------------- + +- compileall.py now avoids recompiling .py files that haven't changed; +it adds a -f option to force recompilation. + +- New version of xmllib.py by Sjoerd Mullender (0.2 with latest +patches). + +- nntplib.py: statparse() no longer lowercases the message-id. + +- types.py: use type(__stdin__) for FileType. + +- urllib.py: fix translations for filenames with "funny" characters. +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. + + +====================================================================== + + From 1.5 to 1.5.1 ================= |
