Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitzc5e060d2006-08-02 06:14:22 +000015- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
16 returned a long (see PEP 353).
17
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000018- Bug #1515471: string.replace() accepts character buffers again.
19
Neal Norwitz07aadb12006-07-30 06:55:48 +000020- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
21 This provides the proper warning for struct.pack().
22 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
23
Neal Norwitz0d62a062006-07-30 06:53:31 +000024- Patch #1531113: Fix augmented assignment with yield expressions.
25 Also fix a SystemError when trying to assign to yield expressions.
26
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000027- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
28 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
29 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
30 excessive filesystem operations during imports.
31
Tim Petersbc24eee2006-07-27 01:14:53 +000032- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
33 operations on signed longs that are formally undefined by C.
34 Unfortunately, at least one compiler now cares about that, so complicated
35 the code to make that compiler happy again.
36
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000037- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
38
Martin v. Löwisd22968a2006-07-24 11:54:53 +000039- Patch #1232023: Stop including current directory in search
40 path on Windows.
41
Neal Norwitze1fdb322006-07-21 05:32:28 +000042- Fix some potential crashes found with failmalloc.
43
Neal Norwitze7563102006-07-17 01:00:16 +000044- Fix warnings reported by Klocwork's static analysis tool.
45
Neal Norwitz84be93b2006-07-16 01:50:38 +000046- Bug #1512814, Fix incorrect lineno's when code within a function
47 had more than 255 blank lines.
48
Georg Brandl9dceedb2006-07-12 15:31:17 +000049- Patch #1521179: Python now accepts the standard options ``--help`` and
50 ``--version`` as well as ``/?`` on Windows.
51
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000052- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000053 again. Fixing this problem required changing the .pyc magic number.
54 This means that .pyc files generated before 2.5c1 will be regenerated.
55
Tim Peters112aad32006-07-19 00:03:19 +000056- Bug #1524317: Compiling Python ``--without-threads`` failed.
57 The Python core compiles again then, and, in a build without threads, the
58 new ``sys._current_frames()`` returns a dictionary with one entry,
59 mapping the faux "thread id" 0 to the current frame.
60
Ronald Oussoren3075e162006-07-25 20:28:55 +000061- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000062
Ronald Oussoren3075e162006-07-25 20:28:55 +000063
Neal Norwitza1f10902006-07-12 07:28:29 +000064Library
65-------
66
Georg Brandl07fec3a2006-08-01 18:49:24 +000067- os.urandom no longer masks unrelated exceptions like SystemExit or
68 KeyboardInterrupt.
69
Martin v. Löwis4e678382006-07-30 13:00:31 +000070- Bug #1525866: Don't copy directory stat times in
71 shutil.copytree on Windows
72
Georg Brandle34ac7c2006-07-30 11:07:23 +000073- Bug #1002398: The documentation for os.path.sameopenfile now correctly
74 refers to file descriptors, not file objects.
75
Fred Drakefbdeaad2006-07-29 16:56:15 +000076- Rename of the xml package to xmlcore, and the import hackery done to
77 make it appear at both names, has been removed. Bug #1511497,
78 #1513611, and probably others.
79
Georg Brandledd9b0d2006-07-29 09:33:26 +000080- Bug #1441397: The compiler module now recognizes module and function
81 docstrings correctly as it did in Python 2.4.
82
Tim Peters6f681472006-07-27 23:44:37 +000083- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
84 lost that tests are sorted by name before being run. This rarely
85 matters for well-written tests, but can create baffling symptoms if
86 side effects from one test to the next affect outcomes. ``DocTestFinder``
87 has been changed to sort the list of tests it returns.
88
Martin v. Löwis1f30c372006-07-30 13:14:05 +000089- The distutils version has been changed to 2.5.0, and are now kept
90 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +000091
Martin v. Löwis9298eff2006-07-26 12:12:56 +000092- Bug #978833: Really close underlying socket in _socketobject.close.
93
Georg Brandl0619a322006-07-26 07:40:17 +000094- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
95 with title().
96
Georg Brandlcf0c1722006-07-26 07:23:32 +000097- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
98 to recursive calls and call it with the failing package name.
99
Martin v. Löwis0b483032006-07-25 09:53:12 +0000100- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
101
Georg Brandlc13c34c2006-07-24 14:09:56 +0000102- Patch #1515343: Fix printing of deprecated string exceptions with a
103 value in the traceback module.
104
Greg Ward48fae7a2006-07-23 16:05:51 +0000105- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
106
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000107- Patch #1524429: Use repr() instead of backticks in Tkinter again.
108
Brett Cannoncaebe222006-07-18 04:41:36 +0000109- Bug #1520914: Change time.strftime() to accept a zero for any position in its
110 argument tuple. For arguments where zero is illegal, the value is forced to
111 the minimum value that is correct. This is to support an undocumented but
112 common way people used to fill in inconsequential information in the time
113 tuple pre-2.4.
114
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000115- Patch #1220874: Update the binhex module for Mach-O.
116
Barry Warsawb110bad2006-07-21 14:51:07 +0000117- The email package has improved RFC 2231 support, specifically for
118 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
119 (name*0=<blah>) parameter continuations. This may change the types of
120 values returned from email.message.Message.get_param() and friends.
121 Specifically in some cases where non-encoded continuations were used,
122 get_param() used to return a 3-tuple of (None, None, string) whereas now it
123 will just return the string (since non-encoded continuations don't have
124 charset and language parts).
125
126 Also, whereas % values were decoded in all parameter continuations, they are
127 now only decoded in encoded parameter parts.
128
Ronald Oussoren3075e162006-07-25 20:28:55 +0000129- Bug #1517990: IDLE keybindings on MacOS X now work correctly
130
131- Bug #1517996: IDLE now longer shows the default Tk menu when a
132 path browser, class browser or debugger is the frontmost window on MacOS X
133
Barry Warsaw00decd72006-07-27 23:43:15 +0000134- Patch #1520294: Support for getset and member descriptors in types.py,
135 inspect.py, and pydoc.py. Specifically, this allows for querying the type
136 of an object against these built-in types and more importantly, for getting
137 their docstrings printed in the interactive interpreter's help() function.
138
Ronald Oussoren3075e162006-07-25 20:28:55 +0000139
Neal Norwitza1f10902006-07-12 07:28:29 +0000140Extension Modules
141-----------------
142
Thomas Heller1393d6a2006-07-28 21:43:20 +0000143- Patch #1529514: The _ctypes extension is now compiled on more
144 openbsd target platforms.
145
Tim Peters9cab5932006-07-28 00:30:00 +0000146- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
147 a memory leak, affecting pickles and deep copies.
148
Tim Petersbc24eee2006-07-27 01:14:53 +0000149- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

153
Thomas Hellerce049a02006-07-14 17:51:14 +0000154- Patch #1521817: Index range checking on ctypes arrays containing
155 exactly one element enabled again. This allows iterating over these
156 arrays, without the need to check the array size before.
157
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000158- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000159 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000160 /dev/null in certain cases; this is now fixed.
161
Thomas Heller47d7a062006-07-12 08:43:47 +0000162- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
163 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000164
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000165- Because of a misspelled preprocessor symbol, ctypes was always
166 compiled without thread support; this is now fixed.
167
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000168- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
169 methods now allow their database parameter to be None as the
170 sleepycat API allows.
171
Matt Flemingec926502006-07-28 11:27:27 +0000172- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
173 bluetooth API compared with Linux and FreeBSD.
174
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000175Tests
176-----
177
178- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
179 how long the test file should take to play. Now accepts taking 2.93 secs
180 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
181
Georg Brandl4793aa32006-07-28 18:31:39 +0000182- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
183 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
184 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000185
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000186Build
187-----
188
189- Bug #1439538: Drop usage of test -e in configure as it is not portable.
190
Ronald Oussoren26cad082006-08-01 21:00:57 +0000191Mac
192---
193
194- PythonLauncher now works correctly when the path to the script contains
195 characters that are treated specially by the shell (such as quotes).
196
197- Bug #1527397: PythonLauncher now launches scripts with the working directory
198 set to the directory that contains the script instead of the user home
199 directory. That latter was an implementation accident and not what users
200 expect.

Georg Brandlad29e632006-06-21 17:45:17 +0000203What's New in Python 2.5 beta 2?
204================================
205
Anthony Baxter70e8e872006-07-10 07:41:04 +0000206*Release date: 11-JUL-2006*
Georg Brandlad29e632006-06-21 17:45:17 +0000207
208Core and builtins
209-----------------
210
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000211- Bug #1441486: The literal representation of -(sys.maxint - 1)
212 again evaluates to a int object, not a long.
213
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000214- Bug #1501934: The scope of global variables that are locally assigned
215 using augmented assignment is now correctly determined.
216
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000217- Bug #927248: Recursive method-wrapper objects can now safely
218 be released.
219
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000220- Bug #1417699: Reject locale-specific decimal point in float()
221 and atof().
222
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000223- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
224 omit a default "error" argument for NULL pointer. This allows
225 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000226
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000227- Bug #1519018: 'as' is now validated properly in import statements.
228
Neal Norwitz28746ab2006-07-09 22:14:42 +0000229- On 64 bit systems, int literals that use less than 64 bits are
230 now ints rather than longs.
231
Neal Norwitzed657552006-07-10 00:04:44 +0000232- Bug #1512814, Fix incorrect lineno's when code at module scope
233 started after line 256.
234
Tim Peters32a83612006-07-10 21:08:24 +0000235- New function ``sys._current_frames()`` returns a dict mapping thread
236 id to topmost thread stack frame. This is for expert use, and is
237 especially useful for debugging application deadlocks. The functionality
238 was previously available in Fazal Majid's ``threadframe`` extension
239 module, but it wasn't possible to do this in a wholly threadsafe way from
240 an extension.
241
Georg Brandlad29e632006-06-21 17:45:17 +0000242Library

Martin v. Löwis8d656812006-07-10 07:23:48 +0000251 environment variable to be set in order to the SDK environment
252 for finding the compiler, include files, etc.
253

257
Thomas Woutersadd19112006-07-05 11:03:49 +0000258- string.Template() now correctly handles tuple-values. Previously,
259 multi-value tuples would raise an exception and single-value tuples would
260 be treated as the value they contain, instead.
261
Martin v. Löwisede77f52006-07-03 13:01:35 +0000262- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

269 degrees and radians.
270
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000271- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000272 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000273
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000274- Bug #1514703: Only setup canvas window in turtle when the canvas
275 is created.
276
Martin v. Löwis7596e832006-07-01 15:33:37 +0000277- Bug #1513223: .close() of a _socketobj now releases the underlying
278 socket again, which then gets closed as it becomes unreferenced.
279
Fred Drake10497c82006-06-29 02:57:48 +0000280- Bug #1504333: Make sgmllib support angle brackets in quoted

285
Georg Brandl1be63af2006-06-28 20:23:25 +0000286- Fix a bug in the turtle module's end_fill function.
287
Brett Cannon53ab5b72006-06-22 16:49:14 +0000288- Bug #1510580: The 'warnings' module improperly required that a Warning
289 category be either a types.ClassType and a subclass of Warning. The proper
290 check is just that it is a subclass with Warning as the documentation states.
291
Georg Brandlad29e632006-06-21 17:45:17 +0000292- The compiler module now correctly compiles the new try-except-finally
293 statement (bug #1509132).
294
Neal Norwitz60373cd2006-06-22 06:30:50 +0000295- The wsgiref package is now installed properly on Unix.
296
Vinay Sajip28e57612006-07-01 10:45:20 +0000297- A bug was fixed in logging.config.fileConfig() which caused a crash on
298 shutdown when fileConfig() was called multiple times.
299
Gerhard Häring762fbd32006-07-02 17:48:30 +0000300- The sqlite3 module did cut off data from the SQLite database at the first
301 null character before sending it to a custom converter. This has been fixed
302 now.
303
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000304Extension Modules
305-----------------
306
Tim Peters112aad32006-07-19 00:03:19 +0000307- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
308 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
309 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000310
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000311- Assigning None to pointer type fields in ctypes structures possible
312 overwrote the wrong fields, this is fixed now.
313
314- Fixed a segfault in _ctypes when ctypes.wintypes were imported
315 on non-Windows platforms.
316
317- Bug #1518190: The ctypes.c_void_p constructor now accepts any
318 integer or long, without range checking.
319
320- Patch #1517790: It is now possible to use custom objects in the ctypes
321 foreign function argtypes sequence as long as they provide a from_param
322 method, no longer is it required that the object is a ctypes type.
323
324- The '_ctypes' extension module now works when Python is configured
325 with the --without-threads option.
326
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000327- Bug #1513646: os.access on Windows now correctly determines write
328 access, again.
329
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000330- Bug #1512695: cPickle.loads could crash if it was interrupted with
331 a KeyboardInterrupt.
332
Neal Norwitza12aa882006-07-06 06:45:08 +0000333- Bug #1296433: parsing XML with a non-default encoding and
334 a CharacterDataHandler could crash the interpreter in pyexpat.
335
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000336- Patch #1516912: improve Modules support for OpenVMS.

339-----
340
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000341- Automate Windows build process for the Win64 SSL module.
342
Tim Peters32a83612006-07-10 21:08:24 +0000343- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000344 Previously, the slight difference could cause compilation errors of the
345 'zlib' module on systems with more than one version of zlib.
346
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000347- The MSI compileall step was fixed to also support a TARGETDIR
348 with spaces in it.
349
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000350- Bug #1517388: sqlite3.dll is now installed on Windows independent
351 of Tcl/Tk.
352
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000353- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000354 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000356Tests
357-----
358
359- Call os.waitpid() at the end of tests that spawn child processes in order
360 to minimize resources (zombies).
361
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000362Documentation
363-------------
364
Nick Coghlan2d792252006-07-06 13:47:18 +0000365- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
366 documentation for the warnings module.
367
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000368- Patch #1509163: MS Toolkit Compiler no longer available.
369
Neal Norwitz56640df2006-07-10 02:36:41 +0000370- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000372What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000373================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000374
Anthony Baxterd1136802006-06-19 12:04:15 +0000375*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000376
377Core and builtins
378-----------------
379
Georg Brandla56b9152006-06-19 06:35:54 +0000380- Patch #1507676: Error messages returned by invalid abstract object operations
381 (such as iterating over an integer) have been improved and now include the
382 type of the offending object to help with debugging.
383
Brett Cannonea3912b2006-06-13 21:46:41 +0000384- Bug #992017: A classic class that defined a __coerce__() method that returned
385 its arguments swapped would infinitely recurse and segfault the interpreter.
386
Neal Norwitz909eb122006-06-12 02:13:21 +0000387- Fix the socket tests so they can be run concurrently.
388
Neal Norwitzb9845e72006-06-12 02:11:18 +0000389- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000390 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000391
Brett Cannon22565aa2006-06-09 22:31:23 +0000392- Bug #532646: object.__call__() will continue looking for the __call__
393 attribute on objects until one without one is found. This leads to recursion
394 when you take a class and set its __call__ attribute to an instance of the
395 class. Originally fixed for classic classes, but this fix is for new-style.
396 Removes the infinite_rec_3 crasher.
397
Georg Brandl24250812006-06-09 18:45:48 +0000398- The string and unicode methods startswith() and endswith() now accept
399 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
400
Brett Cannonde3b0522006-06-08 17:00:45 +0000401- Buffer objects, at the C level, never used the char buffer
402 implementation even when the char buffer for the wrapped object was
403 explicitly requested (originally returned the read or write buffer).
404 Now a TypeError is raised if the char buffer is not present but is
405 requested.
406
Georg Brandlddbaa662006-06-04 21:56:52 +0000407- Patch #1346214: Statements like "if 0: suite" are now again optimized
408 away like they were in Python 2.4.
409
Georg Brandlb7c8f542006-05-27 12:30:25 +0000410- Builtin exceptions are now full-blown new-style classes instead of
411 instances pretending to be classes, which speeds up exception handling
412 by about 80% in comparison to 2.5a2.
413
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000414- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
415 Unicode 4.1.
416
Georg Brandlf4ef1162006-05-26 18:03:31 +0000417- Patch #921466: sys.path_importer_cache is now used to cache valid and
418 invalid file paths for the built-in import machinery which leads to
419 fewer open calls on startup.
420
Tim Peters696cf432006-05-24 21:10:40 +0000421- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
422 of-2 bases. The largest speedup is for inputs with about 1000 decimal
423 digits. Conversion from non-power-of-2 bases remains quadratic-time in
424 the number of input digits (it was and remains linear-time for bases
425 2, 4, 8, 16 and 32).
426
Tim Petersb713ec22006-05-23 18:45:30 +0000427- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
428 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
429 an integer close to ``sys.maxint``. This was repaired by patch
430 #1335972, which also gives a nice speedup.
431
Richard Jonescebbefc2006-05-23 18:28:17 +0000432- Patch #1337051: reduced size of frame objects.
433
434- PyErr_NewException now accepts a tuple of base classes as its
435 "base" parameter.
436
Richard Jones7c88dcc2006-05-23 10:37:38 +0000437- Patch #876206: function call speedup by retaining allocated frame
438 objects.
439
Georg Brandl7b90e162006-05-18 07:01:27 +0000440- Bug #1462152: file() now checks more thoroughly for invalid mode
441 strings and removes a possible "U" before passing the mode to the
442 C library function.
443
Neal Norwitz1004a532006-05-15 07:17:23 +0000444- Patch #1488312, Fix memory alignment problem on SPARC in unicode
445
Neal Norwitz373f0a72006-05-15 07:04:36 +0000446- Bug #1487966: Fix SystemError with conditional expression in assignment
447
Martin v. Löwis879768d2006-05-11 13:28:43 +0000448- WindowsError now has two error code attributes: errno, which carries
449 the error values from errno.h, and winerror, which carries the error
450 values from winerror.h. Previous versions put the winerror.h values
451 (from GetLastError()) into the errno attribute.
452
Martin v. Löwis77736712006-05-04 05:51:03 +0000453- Patch #1475845: Raise IndentationError for unexpected indent.
454
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000455- Patch #1479181: split open() and file() from being aliases for each other.
456
Tim Peters44bd9862006-06-01 13:49:23 +0000457- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
458 methods were always silently ignored by dictionaries when comparing keys.
459 They are now passed through (except when using the C API function
460 ``PyDict_GetItem()``, whose semantics did not change).
461
462- Bug #1456209: In some obscure cases it was possible for a class with a
463 custom ``__eq__()`` method to confuse dict internals when class instances
464 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
465 No, you don't have any code that did this ;-)

471
472- Patch #1462338: Upgrade pyexpat to expat 2.0.0
473
Brett Cannon6ee7d012006-06-08 16:23:04 +0000474- Change binascii.hexlify to accept a read-only buffer instead of only a char
475 buffer and actually follow its documentation.
476
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000477- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
478
Nick Coghlanc649ec52006-05-29 12:43:05 +0000479- Patch #1478788 (modified version): The functional extension module has
480 been renamed to _functools and a functools Python wrapper module added.
481 This provides a home for additional function related utilities that are
482 not specifically about functional programming. See PEP 309.
483
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000484- Patch #1493701: performance enhancements for struct module.
485
Georg Brandl378d5922006-05-17 14:26:50 +0000486- Patch #1490224: time.altzone is now set correctly on Cygwin.
487
Georg Brandl8d3342b2006-05-16 07:38:27 +0000488- Patch #1435422: zlib's compress and decompress objects now have a
489 copy() method.
490
Andrew MacIntyre92913322006-06-13 15:04:24 +0000491- Patch #1454481: thread stack size is now tunable at runtime for thread
492 enabled builds on Windows and systems with Posix threads support.
493
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000494- On Win32, os.listdir now supports arbitrarily-long Unicode path names
495 (up to the system limit of 32K characters).
496
497- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
498 As a result, these functions now raise WindowsError instead of OSError.
499
Tim Peters7a822da2006-05-25 21:50:17 +0000500- ``time.clock()`` on Win64 should use the high-performance Windows
501 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
502 Windows platforms).
503
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000504- Calling Tk_Init twice is refused if the first call failed as that
505 may deadlock.
506
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000507- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
508 accept it without potentially using an uninitialized pointer.
509
510- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
511 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
512 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000513
Gregory P. Smith372b5832006-06-05 18:48:21 +0000514- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000515 [pybsddb project SF patch number 1466734]
516
Gregory P. Smith372b5832006-06-05 18:48:21 +0000517- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
518 parameter is supplied. [SF pybsddb bug #1477863]
519
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000520- bsddb: the __len__ method of a DB object has been fixed to return correct
521 results. It could previously incorrectly return 0 in some cases.
522 Fixes SF bug 1493322 (pybsddb bug 1184012).
523
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000524- bsddb: the bsddb.dbtables Modify method now raises the proper error and
525 aborts the db transaction safely when a modifier callback fails.
526 Fixes SF python patch/bug #1408584.
527
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000528- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000529 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000530 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
531 database calls that would previously deadlock. [SF python bug #775414]
532
Vinay Sajip28e57612006-07-01 10:45:20 +0000533- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000534
Walter Dörwald4994d952006-06-19 08:07:50 +0000535- Patch #1506645: add Python wrappers for the curses functions
536 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000537
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000538Library
539-------
540
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000541- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
542 functions.
543
Martin v. Löwis3798da02006-06-17 18:44:27 +0000544- Patch #812986: Update turtle output even if not tracing.
545
Vinay Sajip28e57612006-07-01 10:45:20 +0000546- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000547 Tkinter.BaseWidget.
548
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000549- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
550
Martin v. Löwis337487e2006-06-17 09:15:14 +0000551- Patch #763580: Add name and value arguments to Tkinter variable
552 classes.
553
Georg Brandl83cc0d02006-06-14 08:50:03 +0000554- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
555 mime.types file for determining MIME types.
556
Georg Brandl2605ca82006-06-14 06:08:31 +0000557- Bug #1339007: Shelf objects now don't raise an exception in their
558 __del__ method when initialization failed.
559
Martin v. Löwisd8251432006-06-14 05:21:04 +0000560- Patch #1455898: The MBCS codec now supports the incremental mode for
561 double-byte encodings.
562
Tim Peters43898b42006-06-14 04:09:25 +0000563- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
564 guarantee that adjacent triples in the return list always describe
565 non-adjacent blocks. Previously, a pair of matching blocks could end
566 up being described by multiple adjacent triples that formed a partition
567 of the matching pair.
568
Greg Ward0e0c9f42006-06-11 16:24:11 +0000569- Bug #1498146: fix optparse to handle Unicode strings in option help,
570 description, and epilog.
571
Greg Wardd1c797e2006-06-11 14:42:41 +0000572- Bug #1366250: minor optparse documentation error.
573
Greg Ward7f547402006-06-11 00:40:49 +0000574- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
575 clarify docs.
576
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000577- The wsgiref package has been added to the standard library.
578
Nick Coghlan676725d2006-06-08 13:54:49 +0000579- The functions update_wrapper() and wraps() have been added to the functools
580 module. These make it easier to copy relevant metadata from the original
581 function when writing wrapper functions.
582
Tim Petersd6a9eef2006-06-05 01:48:21 +0000583- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
584 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000585
Martin v. Löwis3f767792006-06-04 19:36:28 +0000586- Patch #1359618: Speed up charmap encoder by using a trie structure
587 for lookup.
588
Tim Petersd609b1a2006-06-02 23:22:51 +0000589- The functions in the ``pprint`` module now sort dictionaries by key
590 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
591 if and only if its display required more than one line, although that
592 wasn't documented. The new behavior increases predictability; e.g.,
593 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
594
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000595- Patch #1497027: try HTTP digest auth before basic auth in urllib2
596 (thanks for J. J. Lee).
597
Georg Brandl2b330372006-05-28 20:23:12 +0000598- Patch #1496206: improve urllib2 handling of passwords with respect to
599 default HTTP and HTTPS ports.
600
George Yoshidaf3c65de2006-05-28 16:39:09 +0000601- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
602
Bob Ippolito7298f272006-05-23 18:43:47 +0000603- Patch #1281707: speed up gzip.readline.
604
Georg Brandlb89316f2006-05-17 15:51:16 +0000605- Patch #1180296: Two new functions were added to the locale module:
606 format_string() to get the effect of "format % items" but locale-aware,
607 and currency() to format a monetary number with currency sign.
608
Georg Brandle3a25832006-05-17 14:56:04 +0000609- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
610 and several features added, such as speed and geometry control.
611
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000612- Patch #1488881: add support for external file objects in bz2 compressed
613 tarfiles.
614
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000615- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
616 stdout arguments, making it possible to redirect input and output
617 for remote debugging.
618
619- Patch #1484695: Update the tarfile module to version 0.8. This fixes
620 a couple of issues, notably handling of long file names using the
621 GNU LONGNAME extension.
622
623- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
624 new flag when ``name`` is already the name of an option flag.
625
626- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
627 package.
628
629- Patch #1472854: make the rlcompleter.Completer class usable on non-
630 UNIX platforms.
631

664
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000665What's New in Python 2.5 alpha 2?
666=================================
667
668*Release date: 27-APR-2006*
669
670Core and builtins
671-----------------
672
Thomas Heller1b046642006-04-18 18:51:06 +0000673- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
674 by converting these apis from macros into exported functions again:
675
676 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
677 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
678 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
679 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
680 PyRun_String Py_CompileString
681
Martin v. Löwis45294a92006-04-18 06:24:08 +0000682- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
683
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000684- All uses of PyStructSequence_InitType have been changed to initialize
685 the type objects only once, even if the interpreter is initialized
686 multiple times.
687
Neal Norwitz61546162006-04-14 05:20:28 +0000688- Bug #1454485, array.array('u') could crash the interpreter. This was
689 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
690 to unicode when it didn't make sense. 'u#' now requires a unicode string.
691
692- Py_UNICODE is unsigned. It was always documented as unsigned, but
693 due to a bug had a signed value in previous versions.
694
Tim Peters3a5e8b12006-04-11 01:44:07 +0000695- Patch #837242: ``id()`` of any Python object always gives a positive
696 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
697 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000698 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000699 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000700
Tim Peters3a5e8b12006-04-11 01:44:07 +0000701 def __hash__(self):
702 return id(self) # WRONG
703
704 because a hash result must be a (short) Python int but it was always
705 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000706 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000707 was always usable as a hash value before this patch. That's no longer
708 necessarily so.
709
710- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000711 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000712 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000713 #1454844)
714
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000715- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
716 involving generators that have paused outside of any ``try`` or ``with``
717 blocks. (In 2.5a1, a paused generator that was part of a reference
718 cycle could not be garbage collected, regardless of whether it was
719 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000721Extension Modules

723
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000724- Patch #1191065: Fix preprocessor problems on systems where recvfrom
725 is a macro.
726
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000727- Bug #1467952: os.listdir() now correctly raises an error if readdir()
728 fails with an error condition.
729
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000730- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
731
732- Bug #1117761: bsddb.*open() no longer raises an exception when using
733 the cachesize parameter.
734
735- Bug #1149413: bsddb.*open() no longer raises an exception when using
736 a temporary db (file=None) with the 'n' flag to truncate on open.
737
738- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
739 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000740
Armin Rigoa9017c32006-04-19 11:50:27 +0000741- Patch #1062014: AF_UNIX sockets under Linux have a special
742 abstract namespace that is now fully supported.
743
Anthony Baxter51bcb682006-04-05 14:51:42 +0000744Library
745-------
746
Peter Astrand7d1d4362006-07-14 14:04:45 +0000747- Bug #1223937: subprocess.CalledProcessError reports the exit status
748 of the process using the returncode attribute, instead of
749 abusing errno.
750
Tim Peters711bf302006-04-25 03:31:36 +0000751- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
752 a doctest to be skipped (the code is not run, and the expected output
753 or exception is ignored).
754
Nick Coghlanda2268f2006-04-24 04:37:15 +0000755- Fixed contextlib.nested to cope with exceptions being raised and
756 caught inside exit handlers.
757
Greg Wardab05edc2006-04-23 03:47:58 +0000758- Updated optparse module to Optik 1.5.1 (allow numeric constants in
759 hex, octal, or binary; add ``append_const`` action; keep going if
760 gettext cannot be imported; added ``OptionParser.destroy()`` method;
761 added ``epilog`` for better help generation).
762
Tim Peters21fbd572006-04-21 21:18:10 +0000763- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
764 called from a thread spawned as a side effect of importing a module.
765
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000766- The pydoc module now supports documenting packages contained in
767 .zip or .egg files.
768
769- The pkgutil module now has several new utility functions, such
770 as ``walk_packages()`` to support working with packages that are either
771 in the filesystem or zip files.
772
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000773- The mailbox module can now modify and delete messages from
774 mailboxes, in addition to simply reading them. Thanks to Gregory
775 K. Johnson for writing the code, and to the 2005 Google Summer of
776 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000777
Tim Petersc7605f22006-04-17 21:12:33 +0000778- The ``__del__`` method of class ``local`` in module ``_threading_local``
779 returned before accomplishing any of its intended cleanup.
780
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000781- Patch #790710: Add breakpoint command lists in pdb.
782
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000783- Patch #1063914: Add Tkinter.Misc.clipboard_get().
784
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000785- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
786
Anthony Baxtere29002c2006-04-12 12:07:31 +0000787- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
788 Windows. Bug #1469163.
789
Phillip J. Eby47032112006-04-11 01:07:43 +0000790- The warnings, linecache, inspect, traceback, site, and doctest modules
791 were updated to work correctly with modules imported from zipfiles or
792 via other PEP 302 __loader__ objects.
793
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000794- Patch #1467770: Reduce usage of subprocess._active to processes which
795 the application hasn't waited on.
796
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000797- Patch #1462222: Fix Tix.Grid.
798
Neal Norwitza31bf182006-04-09 03:35:43 +0000799- Fix exception when doing glob.glob('anything*/')
800
Skip Montanaro262fb922006-04-21 02:31:07 +0000801- The pstats.Stats class accepts an optional stream keyword argument to
802 direct output to an alternate file-like object.
803
Anthony Baxter51bcb682006-04-05 14:51:42 +0000804Build
805-----
806
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000807- The Makefile now has a reindent target, which runs reindent.py on
808 the library.
809
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000810- Patch #1470875: Building Python with MS Free Compiler
811
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000812- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000813
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000814- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
815 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000816 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000817 CXX from --with-cxx-main, see description in README.
818
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000819- Patch #1429775: Link extension modules with the shared libpython.
820
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000821- Fixed a libffi build problem on MIPS systems.
822
Tim Peters8931ff12006-05-13 23:28:20 +0000823- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
824 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
825 and "%zu" for unsigned integers of type ``size_t``.
826
Anthony Baxter51bcb682006-04-05 14:51:42 +0000827Tests
828-----
829
Nick Coghlanda2268f2006-04-24 04:37:15 +0000830- test_contextlib now checks contextlib.nested can cope with exceptions
831 being raised and caught inside exit handlers.
832
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000833- test_cmd_line now checks operation of the -m and -c command switches
834
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000835- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
836 it separately and by hand. It also wasn't cleaning up its changes to
837 the current Decimal context.
838
Thomas Woutersabd08882006-04-26 15:53:30 +0000839- regrtest.py now has a -M option to run tests that test the new limits of
840 containers, on 64-bit architectures. Running these tests is only sensible
841 on 64-bit machines with more than two gigabytes of memory. The argument
842 passed is the maximum amount of memory for the tests to use.

851-------------
852
Tim Petersb06d28c2006-05-12 01:57:59 +0000853- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
854
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000855- PEP 343: Added Context Types section to the library reference
856 and attempted to bring other PEP 343 related documentation into
857 line with the implementation and/or python-dev discussions.
858
Tim Peters8dc73d22006-04-24 02:03:16 +0000859- Bug #1337990: clarified that ``doctest`` does not support examples
860 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000863What's New in Python 2.5 alpha 1?
864=================================
865
Anthony Baxterebed3f62006-04-03 15:03:44 +0000866*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000867
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000868Core and builtins
869-----------------
870
Nick Coghlan43832302006-04-23 17:04:07 +0000871- PEP 338: -m command line switch now delegates to runpy.run_module
872 allowing it to support modules in packages and zipfiles
873
Martin v. Löwisc661b882006-04-20 04:54:23 +0000874- On Windows, .DLL is not an accepted file name extension for
875 extension modules anymore; extensions are only found if they
876 end in .PYD.
877
Martin v. Löwisea62d252006-04-03 10:56:49 +0000878- Bug #1421664: sys.stderr.encoding is now set to the same value as
879 sys.stdout.encoding.
880
Neal Norwitz92e212f2006-04-03 04:48:37 +0000881- __import__ accepts keyword arguments.
882
Georg Brandlccadf842006-03-31 18:54:53 +0000883- Patch #1460496: round() now accepts keyword arguments.
884
Anthony Baxter262c00a2006-03-30 10:53:17 +0000885- Fixed bug #1459029 - unicode reprs were double-escaped.
886
Hye-Shik Changd478f342006-03-23 12:32:36 +0000887- Patch #1396919: The system scope threads are reenabled on FreeBSD
888 5.4 and later versions.
889
Neal Norwitze98ccf62006-03-23 05:39:47 +0000890- Bug #1115379: Compiling a Unicode string with an encoding declaration
891 now gives a SyntaxError.
892
Georg Brandlabd1ff82006-03-18 07:59:59 +0000893- Previously, Python code had no easy way to access the contents of a
894 cell object. Now, a ``cell_contents`` attribute has been added
895 (closes patch #1170323).
896
Tim Peterscf79aac2006-03-16 01:14:46 +0000897- Patch #1123430: Python's small-object allocator now returns an arena to
898 the system ``free()`` when all memory within an arena becomes unused
899 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
900 freed. Some applications will see a drop in virtual memory size now,
901 especially long-running applications that, from time to time, temporarily
902 use a large number of small objects. Note that when Python returns an
903 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000904 platform C library will in turn return that memory to the operating system.
905 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000906 appears to be effective at least on Microsoft C and gcc-based systems.
907 Thanks to Evan Jones for hard work and patience.
908
Georg Brandl533ff6f2006-03-08 18:09:27 +0000909- Patch #1434038: property() now uses the getter's docstring if there is
910 no "doc" argument given. This makes it possible to legitimately use
911 property() as a decorator to produce a read-only property.
912
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000913- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
914 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
915 of requiring an int or long in slicing and a few other contexts, enabling
916 other objects (e.g. Numeric Python's integers) to be used as slice indices.
917
Neal Norwitz995acdf2006-03-07 05:01:00 +0000918- Fixed various bugs reported by Coverity's Prevent tool.
919
Brett Cannonbf364092006-03-01 04:25:17 +0000920- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
921 new exception base class, BaseException, which has a new message attribute.
922 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
923 Raising a string exception now raises a DeprecationWarning.
924
Thomas Woutersfb609f42006-02-28 16:37:25 +0000925- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
926 explicitly relative, using 'from .module import name' to mean 'from the same
927 package as this module is in. Imports without dots still default to the
928 old relative-then-absolute, unless 'from __future__ import
929 absolute_import' is used.
930
Brett Cannona7446e32006-02-27 23:39:10 +0000931- Properly check if 'warnings' raises an exception (usually when a filter set
932 to "error" is triggered) when raising a warning for raising string
933 exceptions.
934
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000935- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000936 The name was removed from Include/code.h.
937
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000938- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000939
Guido van Rossum1968ad32006-02-25 22:38:04 +0000940- Patch 1433928:
941 - The copy module now "copies" function objects (as atomic objects).
942 - dict.__getitem__ now looks for a __missing__ hook before raising
943 KeyError.
944
Tim Peters84ef21c2006-02-28 20:39:06 +0000945- PEP 343: with statement implemented. Needs ``from __future__ import
946 with_statement``. Use of 'with' as a variable will generate a warning.
947 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000948 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000949 The following objects have __context__ methods:
950 - The built-in file type.
951 - The thread.LockType type.
952 - The following types defined by the threading module:
953 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
954 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000955
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000956- Fix the encodings package codec search function to only search
957 inside its own package. Fixes problem reported in patch #1433198.
958
959 Note: Codec packages should implement and register their own
960 codec search function. PEP 100 has the details.
961
Tim Peters9ea89d22006-06-04 03:26:02 +0000962- PEP 353: Using ``Py_ssize_t`` as the index type.
963
964- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
965 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
966 now allow Python to make use of memory blocks exceeding 2**32 bytes for
967 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
968 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000969
Neal Norwitzfc76d632006-01-10 06:03:13 +0000970- Patch #1400181, fix unicode string formatting to not use the locale.
971 This is how string objects work. u'%f' could use , instead of .
972 for the decimal point. Now both strings and unicode always use periods.
973
Neal Norwitz671b9e32006-01-09 07:07:12 +0000974- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
975 configure would break checking curses.h.
976
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000977- Bug #959576: The pwd module is now builtin. This allows Python to be
978 built on UNIX platforms without $HOME set.
979
Neal Norwitzc10978f2005-12-19 06:07:16 +0000980- Bug #1072182, fix some potential problems if characters are signed.
981
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000982- Bug #889500, fix line number on SyntaxWarning for global declarations.
983
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000984- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
985
Neal Norwitze7214a12005-12-18 05:03:17 +0000986- Support for converting hex strings to floats no longer works.
987 This was not portable. float('0x3') now raises a ValueError.
988
Barry Warsaw2a38a862005-12-18 01:27:35 +0000989- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000990 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000991 is now displayed in interactive prompt banner.
992
Georg Brandlfa166682005-12-17 21:45:17 +0000993- Implementation of PEP 341 - Unification of try/except and try/finally.
994 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000995 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000996
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000997- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
998 now encodes backslash correctly.
999
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001000- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1001
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001002- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001003 and long longs.
1004
Neal Norwitz67715f02005-11-09 06:59:35 +00001005- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001006 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001007 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001008
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001009- Replaced most Unicode charmap codecs with new ones using the
1010 new Unicode translate string feature in the builtin charmap
1011 codec; the codecs were created from the mapping tables available
1012 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1013 encodings now include a mapping for the Apple logo)
1014
Tim Peterse3547fd2005-12-16 23:13:57 +00001015- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001016
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001017- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001018
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001019- A new AST parser implementation was completed. The abstract
1020 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001021 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001022
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001023- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001024 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1025
Neal Norwitz708e51a2005-10-03 04:48:15 +00001026- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1027
Neal Norwitz11bd1192005-10-03 00:54:56 +00001028- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1029 Provide a warning when a directory is passed on the command line.
1030
Neal Norwitz40d37812005-10-02 01:48:49 +00001031- Fix segfault with invalid coding.
1032
1033- SF bug #772896: unknown encoding results in MemoryError.
1034
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001035- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001036 supported a __len__() method which evaluated to False when the iterator
1037 was empty.
1038
Guido van Rossum630db602005-09-20 18:49:54 +00001039- On 64-bit platforms, when __len__() returns a value that cannot be
1040 represented as a C int, raise OverflowError.
1041
Skip Montanarof8948ca2005-09-19 03:54:46 +00001042- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001043 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001044
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001045- SF bug #893549: parsing keyword arguments was broken with a few format
1046 codes.
1047
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001048- Changes donated by Elemental Security to make it work on AIX 5.3
1049 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1050 bug #105470: test_pwd fails on 64bit system (Opteron).
1051
Guido van Rossum539c6622005-09-14 17:49:54 +00001052- Changes donated by Elemental Security to make it work on HP-UX 11 on
1053 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1054
Georg Brandl4550b8d2005-08-26 06:43:52 +00001055- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001056 (fixes bug #1119418).
1057
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001058- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1059
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001060- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1061 exceptions that cause a function to exit.
1062
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001063- The implementation of set() and frozenset() was revised to use its
1064 own internal data structure. Memory consumption is reduced by 1/3
1065 and there are modest speed-ups as well. The API is unchanged.
1066
Tim Petersde7990b2005-07-17 23:45:23 +00001067- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1068
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001069- SF bug #1229429: PyObject_CallMethod failed to decrement some
1070 reference counts in some error exit cases.
1071
Tim Petersecc6e6a2005-07-10 22:30:55 +00001072- SF bug #1185883: Python's small-object memory allocator took over
1073 a block managed by the platform C library whenever a realloc specified
1074 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001075 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001076 portable way to copy data from the C-managed block into Python's
1077 small-object space without risking a memory fault. Python's small-object
1078 realloc now leaves such blocks under the control of the platform C
1079 realloc.
1080
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001081- SF bug #1232517: An overflow error was not detected properly when
1082 attempting to convert a large float to an int in os.utime().
1083
Raymond Hettinger3296e692005-06-29 23:29:56 +00001084- SF bug #1224347: hex longs now print with lowercase letters just
1085 like their int counterparts.
1086
Michael W. Hudson188d4362005-06-20 16:52:57 +00001087- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1088 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1089 interpreter states; back out that fix and do a better job (see
1090 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1091 for a longer write-up of the problem).
1092
Michael W. Hudsondf888462005-06-03 14:41:55 +00001093- SF patch #1180995: marshal now uses a binary format by default when
1094 serializing floats.
1095
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001096- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1097 the routines that promise to produce IEEE 754 binary representations
1098 of floats now simply copy bytes around.
1099
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001100- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1101 278.
1102
Brett Cannonc3647ac2005-04-26 03:45:26 +00001103- patch #1109424: int, long, float, complex, and unicode now check for the
1104 proper magic slot for type conversions when subclassed. Previously the
1105 magic slot was ignored during conversion. Semantics now match the way
1106 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001107 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001108 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001109 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001110
Barry Warsawc8d907c2005-04-19 23:43:40 +00001111- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1112 NULL, now raise an AttributeError when attempting to set or delete the
1113 attribute. Previously a TypeError was raised, but this was inconsistent
1114 with the equivalent pure-Python implementation.
1115
Michael W. Hudson774479c2005-04-18 08:46:17 +00001116- It is now safe to call PyGILState_Release() before
1117 PyEval_InitThreads() (note that if there is reason to believe there
1118 are multiple threads around you still must call PyEval_InitThreads()
1119 before using the Python API; this fix is for extension modules that
1120 have no way of knowing if Python is multi-threaded yet).
1121
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001122- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1123 disabled caused a crash.
1124
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001125- Bug #1165306: instancemethod_new allowed the creation of a method
1126 with im_class == im_self == NULL, which caused a crash when called.
1127
Tim Petersecc6e6a2005-07-10 22:30:55 +00001128- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001129 fixes the crash seen in bug #1165761
1130
Raymond Hettinger96229b12005-03-11 06:49:40 +00001131- Added two new builtins, any() and all().
1132
Brett Cannon409d8f22005-03-05 06:47:57 +00001133- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001134 (e.g., ``class C(): pass`` is no longer a syntax error).
1135 Patch #1176012 added support to the 'parser' module and 'compiler' package
1136 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001137
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001138- Patch #1115086: Support PY_LONGLONG in structmember.
1139
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001140- Bug #1155938: new style classes did not check that __init__() was
1141 returning None.
1142
Tim Petersecc6e6a2005-07-10 22:30:55 +00001143- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001144 ('\') with a specific error message.
1145
Martin v. Löwisff232d72005-03-03 09:24:38 +00001146- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1147
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001148- Bug #1124295: the __name__ attribute of file objects was
1149 inadvertently made inaccessible in restricted mode.
1150
Tim Petersecc6e6a2005-07-10 22:30:55 +00001151- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001152 an ferror() call.
1153
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001154- min() and max() now support key= arguments with the same meaning as in
1155 list.sort().
1156
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001157- The peephole optimizer now performs simple constant folding in expressions:
1158 (2+3) --> (5).
1159
Raymond Hettingera422c342005-01-11 03:03:27 +00001160- set and frozenset objects can now be marshalled. SF #1098985.
1161
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001162- Bug #1077106: Poor argument checking could cause memory corruption
1163 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001164
Jeremy Hyltonab630502005-02-04 18:44:06 +00001165- The parser did not complain about future statements in illegal
1166 positions. It once again reports a syntax error if a future
1167 statement occurs after anything other than a doc string.
1168
Neil Schemenauercf52c072005-08-12 17:34:58 +00001169- Change the %s format specifier for str objects so that it returns a
1170 unicode instance if the argument is not an instance of basestring and
1171 calling __str__ on the argument returns a unicode instance.
1172
Tim Petersf4e69282006-02-27 17:15:31 +00001173- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1174 current thread state when the auto-GIL-state machinery knows about
1175 it (since the thread state is being deleted, continuing to remember it
1176 can't help, but can hurt if another thread happens to get created with
1177 the same thread id).
1178
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001179Extension Modules
1180-----------------
1181
Georg Brandl43f08a82006-03-31 18:01:16 +00001182- Patch #1380952: fix SSL objects timing out on consecutive read()s
1183
Neal Norwitz05a45592006-03-20 06:30:08 +00001184- Patch #1309579: wait3 and wait4 were added to the posix module.
1185
Anthony Baxterfa869072006-03-20 05:21:58 +00001186- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1187 In addition, the existing ulaw code was updated.
1188
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001189- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001190 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001191
Neal Norwitz10be10c2006-03-16 06:50:13 +00001192- Everything under lib-old was removed. This includes the following modules:
1193 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001194 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001195 util, whatsound, whrandom, zmod
1196
1197- The following modules were removed: regsub, reconvert, regex, regex_syntax.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001369- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1370 been renamed to have only a single underscore prefix. This was done to
1371 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001372
Nick Coghlan43832302006-04-23 17:04:07 +00001373- PEP 338: new module runpy defines a run_module function to support
1374 executing modules which provide access to source code or a code object
1375 via the PEP 302 import mechanisms.
1376
Anthony Baxter93f5b932006-04-03 08:05:07 +00001377- The email module's parsedate_tz function now sets the daylight savings

1385 in attribute values.
1386
Anthony Baxterc51ee692006-04-01 00:57:31 +00001387- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001388 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001389 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001390 module will not be built.
1391
Tim Petersc17976e2006-04-01 00:26:53 +00001392- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1393 aren't officially supported here, and trying to use them will probably
1394 raise an exception some day. But dicts have been allowed, and "mostly
1395 worked", so support for them won't go away without warning.
1396
Georg Brandl338ef7d2006-03-31 18:42:16 +00001397- Bug #1445068: getpass.getpass() can now be given an explicit stream

1415
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001416- email 4.0 package now integrated. This is largely the same as the email 3.0
1417 package that was included in Python 2.3, except that PEP 8 module names are
1418 now used (e.g. mail.message instead of email.Message). The MIME classes
1419 have been moved to a subpackage (e.g. email.mime.text instead of
1420 email.MIMEText). The old names are still supported for now. Several
1421 deprecated Message methods have been removed and lots of bugs have been
1422 fixed. More details can be found in the email package documentation.
1423
Walter Dörwald40108c92006-03-27 08:15:44 +00001424- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1425 (a subclass of tuple) that provides incremental decoders and encoders
1426 (a way to use stateful codecs without the stream API). Python functions
1427 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1428 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1429 have been added.

1432 a ValueError instead of a StopIteration now (like file and cString.String do).

1502
Neal Norwitz338e7862005-12-23 21:27:46 +00001503- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1504 LoadError as documented, instead of IOError. For compatibility,
1505 LoadError subclasses IOError.
1506
Brett Cannon3cbd0382005-12-16 22:49:23 +00001507- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001508 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1509 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1510 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1511 Ronald L. Rivest offered this advice for Python:
1512
1513 "The consensus of researchers in this area (at least as
1514 expressed at the NIST Hash Function Workshop 10/31/05),
1515 is that SHA-256 is a good choice for the time being, but
1516 that research should continue, and other alternatives may
1517 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001518
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001519- Added a subset of Fredrik Lundh's ElementTree package. Available

1572 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001573 correct line numbers for decoding errors in source code.

1613
Raymond Hettinger68c04532005-06-10 11:05:19 +00001614- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001615 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001616 the generate_tokens() function now accepts a callable argument that
1617 terminates by raising StopIteration.
1618

1638 work as expected.
1639
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001640- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001678- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1679 disables recursive traversal through instance attributes, which can
1680 be exploited in various ways.
1681
Tim Peterse3547fd2005-12-16 23:13:57 +00001682- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

1696
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001697- Enhancements to the csv module:
1698
1699 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001700 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001701 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001702 + Dialect parameter parsing has been re-implemented to improve error
1703 reporting.
1704 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1705 dictates.
1706 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001707 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001708 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001709 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1710 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001711 + reader now allows \r characters to be quoted (previously it only allowed
1712 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001713 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001714 + Dialect classes passed to the module are no longer instantiated by
1715 the module before being parsed (the former validation scheme required
1716 this, but the mechanism was unreliable).
1717 + The dialect registry now contains instances of the internal
1718 C-coded dialect type, rather than references to python objects.
1719 + the internal c-coded dialect type is now immutable.
1720 + register_dialect now accepts the same keyword dialect specifications
1721 as the reader and writer, allowing the user to register dialects
1722 without first creating a dialect class.
1723 + a configurable limit to the size of parsed fields has been added -
1724 previously, an unmatched quote character could result in the entire
1725 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001726 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001727 the parser field size limit (returning the former limit). The initial
1728 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001729 + A line_num attribute has been added to the reader object, which tracks
1730 the number of lines read from the source iterator. This is not
1731 the same as the number of records returned, as records can span
1732 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001733 + reader and writer objects were not being registered with the cyclic-GC.
1734 This has been fixed.
1735
Brett Cannone6539c42005-01-08 02:43:53 +00001736- _DummyThread objects in the threading module now delete self.__block that is
1737 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1738 lock primitives tend to be limited in number and thus should not be wasted on
1739 a _DummyThread object. Fixes bug #1089632.
1740
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001741- The imghdr module now detects Exif files.
1742
Raymond Hettinger6065d322004-12-20 23:51:53 +00001743- StringIO.truncate() now correctly adjusts the size attribute.
1744 (Bug #951915).
1745
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001746- locale.py now uses an updated locale alias table (built using
1747 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1748 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001749 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001750
Raymond Hettinger3557f422004-12-07 12:02:02 +00001751- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1752
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001753- the pickle module no longer accepts the deprecated None option in the
1754 args tuple returned by __reduce__().
1755
Brett Cannon84667c02004-12-07 03:25:18 +00001756- optparse now optionally imports gettext. This allows its use in setup.py.
1757
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001758- the pickle module no longer uses the deprecated bin parameter.
1759
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001760- the shelve module no longer uses the deprecated binary parameter.
1761
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001762- the pstats module no longer uses the deprecated ignore() method.
1763
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001764- the filecmp module no longer uses the deprecated use_statcache argument.
1765
Raymond Hettinger664347b2004-12-04 21:21:53 +00001766- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1767 extended or overridden by subclasses. Formerly, the subclassed method would
1768 be ignored by the rest of the module. (Bug #1078905).
1769
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001770- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001771 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001772
Walter Dörwald36733692004-12-22 12:50:50 +00001773- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1774 once when a size argument is given. This prevents a buffer overflow in the
1775 tokenizer with very long source lines.
1776
Barry Warsaw538561e2006-01-01 21:48:54 +00001777- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1778 immediately after creating the object, without any intervening
1779 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001780
Skip Montanaro05885812005-01-16 20:48:27 +00001781- The reconvert.quote function can now emit triple-quoted strings. The
1782 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001783
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001784- ``UserString.MutableString`` now supports negative indices in
1785 ``__setitem__`` and ``__delitem__``
1786
Greg Ward40407942005-03-05 02:53:17 +00001787- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1788 correctly.
1789
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001790- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1791 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1792 character even if the user has passed a size parameter to get a proper
1793 line ending. Remove the special handling of a "\r\n" that has been split
1794 between two lines.
1795
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001796- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1797 about illegal code points. The codec now supports PEP 293 style error
1798 handlers.
1799
Walter Dörwald78a78b02005-09-01 12:04:29 +00001800- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001801 from the input stream, so that the output is a byte string in the correct
1802 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001803
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001804- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1805 considering it exactly like a '*'.
1806
Walter Dörwald007f8df2005-10-09 19:42:27 +00001807- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1808 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001809
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001810- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1811
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001812- Patch #1413711: Certain patterns of differences were making difflib
1813 touch the recursion limit.
1814
Walter Dörwald58917a62006-03-31 15:26:22 +00001815- Bug #947906: An object oriented interface has been added to the calendar
1816 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001817 called as a script (e.g. via ``python -mcalendar``). Localized month and
1818 weekday names can be ouput (even if an exotic encoding is used) using
1819 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001820
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001821Build
1822-----
1823
Neal Norwitz602d3392006-03-31 08:21:40 +00001824- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1825 by using -mieee gcc option.
1826
Martin v. Löwis86d66262006-02-17 08:40:11 +00001827- Patch #1432345: Make python compile on DragonFly.
1828
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001829- Build support for Win64-AMD64 was added.
1830
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001831- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1832
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001833- Patch #881820: look for openpty and forkpty also in libbsd.
1834
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001835- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1836 The zlib module is now builtin on Windows.
1837
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001838- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1839
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001840- Bug #1189330: configure did not correctly determine the necessary
1841 value of LINKCC if python was built with GCC 4.0.
1842
Trent Mick8321b422005-07-26 02:29:21 +00001843- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1844 vulnerability in zlib 1.2.1 and 1.2.2.
1845
Brett Cannon08cd5982005-04-24 22:26:38 +00001846- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1847 flags that change binary compatibility. Changes were also made to
1848 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001849 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001850
Bob Ippolitoed233462005-03-29 13:47:59 +00001851- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1852 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1853 no longer exists). This configure patch makes things right.
1854
Martin v. Löwise2713be2005-03-08 15:03:08 +00001855- Bug #1158607: Build with --disable-unicode again.
1856
Brett Cannon46d96232005-02-16 00:07:19 +00001857- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1858 defined. Discovered as a result of not being able to build on OS X.
1859
Brett Cannon516592f2004-12-07 00:42:59 +00001860- setup.py now uses the directories specified in LDFLAGS using the -L option
1861 and in CPPFLAGS using the -I option for adding library and include
1862 directories, respectively, for compiling extension modules against. This has
1863 led to the core being compiled using the values in CPPFLAGS. It also removes
1864 the need for the special-casing of both DarwinPorts and Fink for darwin since
1865 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1866 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1867 Fink, ``-I/opt/local/include`` for DarwinPorts).
1868
Brett Cannon43802422005-02-10 20:48:03 +00001869- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1870 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1871 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1872 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001874C API
1875-----
1876
Tim Petersc9d78aa2006-03-26 23:27:58 +00001877- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1878 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1879 is obtained via the ``PyObject_`` family, it must be released via the
1880 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1881 always been officially true, but when Python's small-object allocator was
1882 introduced, an attempt was made to cater to a few extension modules
1883 discovered at the time that obtained memory via ``PyObject_New`` but
1884 released it via ``PyMem_DEL``. It's years later, and if such code still
1885 exists it will fail now (probably with segfaults, but calling wrong
1886 low-level memory management functions can yield many symptoms).
1887
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001888- Added a C API for set and frozenset objects.
1889
Raymond Hettinger66517482004-12-03 11:45:13 +00001890- Removed PyRange_New().
1891
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001892- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1893 mapping argument now. This string is used as a mapping table. Byte values
1894 greater than the length of the string and 0xFFFE are treated as undefined
1895 mappings.
