Neal Norwitza1f10902006-07-12 07:28:29 +00007What's New in Python 2.5 release candidate 1?
8=============================================

11
12Core and builtins
13-----------------
14
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000015- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
16
Martin v. Löwisd22968a2006-07-24 11:54:53 +000017- Patch #1232023: Stop including current directory in search
18 path on Windows.
19
Neal Norwitze1fdb322006-07-21 05:32:28 +000020- Fix some potential crashes found with failmalloc.
21
Neal Norwitze7563102006-07-17 01:00:16 +000022- Fix warnings reported by Klocwork's static analysis tool.
23
Neal Norwitz84be93b2006-07-16 01:50:38 +000024- Bug #1512814, Fix incorrect lineno's when code within a function
25 had more than 255 blank lines.
26
Georg Brandl9dceedb2006-07-12 15:31:17 +000027- Patch #1521179: Python now accepts the standard options ``--help`` and
28 ``--version`` as well as ``/?`` on Windows.
29
Neal Norwitza1f10902006-07-12 07:28:29 +000030- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
31 again. Fixing this problem required changing the .pyc magic number.
32 This means that .pyc files generated before 2.5c1 will be regenerated.
33
Tim Peters112aad32006-07-19 00:03:19 +000034- Bug #1524317: Compiling Python ``--without-threads`` failed.
35 The Python core compiles again then, and, in a build without threads, the
36 new ``sys._current_frames()`` returns a dictionary with one entry,
37 mapping the faux "thread id" 0 to the current frame.

40-------
41
Georg Brandlc13c34c2006-07-24 14:09:56 +000042- Patch #1515343: Fix printing of deprecated string exceptions with a
43 value in the traceback module.
44
Greg Ward48fae7a2006-07-23 16:05:51 +000045- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
46
Martin v. Löwis426f4a12006-07-18 17:46:31 +000047- Patch #1524429: Use repr() instead of backticks in Tkinter again.
48
Brett Cannoncaebe222006-07-18 04:41:36 +000049- Bug #1520914: Change time.strftime() to accept a zero for any position in its
50 argument tuple. For arguments where zero is illegal, the value is forced to
51 the minimum value that is correct. This is to support an undocumented but
52 common way people used to fill in inconsequential information in the time
53 tuple pre-2.4.
54
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000055- Patch #1220874: Update the binhex module for Mach-O.
56
Barry Warsawb110bad2006-07-21 14:51:07 +000057- The email package has improved RFC 2231 support, specifically for
58 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
59 (name*0=<blah>) parameter continuations. This may change the types of
60 values returned from email.message.Message.get_param() and friends.
61 Specifically in some cases where non-encoded continuations were used,
62 get_param() used to return a 3-tuple of (None, None, string) whereas now it
63 will just return the string (since non-encoded continuations don't have
64 charset and language parts).
65
66 Also, whereas % values were decoded in all parameter continuations, they are
67 now only decoded in encoded parameter parts.

70-----------------
71
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000072- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
73
Thomas Hellerce049a02006-07-14 17:51:14 +000074- Patch #1521817: Index range checking on ctypes arrays containing
75 exactly one element enabled again. This allows iterating over these
76 arrays, without the need to check the array size before.
77
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000078- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000079 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000080 /dev/null in certain cases; this is now fixed.
81
Thomas Heller47d7a062006-07-12 08:43:47 +000082- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
83 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000084
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000085- Because of a misspelled preprocessor symbol, ctypes was always
86 compiled without thread support; this is now fixed.

93Core and builtins
94-----------------
95
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000096- Bug #1441486: The literal representation of -(sys.maxint - 1)
97 again evaluates to a int object, not a long.
98
Neil Schemenauer0e07b602006-07-09 16:16:34 +000099- Bug #1501934: The scope of global variables that are locally assigned
100 using augmented assignment is now correctly determined.
101
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000102- Bug #927248: Recursive method-wrapper objects can now safely
103 be released.
104
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000105- Bug #1417699: Reject locale-specific decimal point in float()
106 and atof().
107
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000108- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
109 omit a default "error" argument for NULL pointer. This allows
110 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000111
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000112- Bug #1519018: 'as' is now validated properly in import statements.
113
Neal Norwitz28746ab2006-07-09 22:14:42 +0000114- On 64 bit systems, int literals that use less than 64 bits are
115 now ints rather than longs.
116
Neal Norwitzed657552006-07-10 00:04:44 +0000117- Bug #1512814, Fix incorrect lineno's when code at module scope
118 started after line 256.
119
Tim Peters32a83612006-07-10 21:08:24 +0000120- New function ``sys._current_frames()`` returns a dict mapping thread
121 id to topmost thread stack frame. This is for expert use, and is
122 especially useful for debugging application deadlocks. The functionality
123 was previously available in Fazal Majid's ``threadframe`` extension
124 module, but it wasn't possible to do this in a wholly threadsafe way from
125 an extension.

131
Tim Peters32a83612006-07-10 21:08:24 +0000132- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000133 environment variable to be set in order to the SDK environment
134 for finding the compiler, include files, etc.
135
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000136- Bug #1515998: Properly generate logical ids for files in bdist_msi.
137
Nick Coghlan2d792252006-07-06 13:47:18 +0000138- warnings.py now ignores ImportWarning by default
139
Thomas Woutersadd19112006-07-05 11:03:49 +0000140- string.Template() now correctly handles tuple-values. Previously,
141 multi-value tuples would raise an exception and single-value tuples would
142 be treated as the value they contain, instead.
143
Martin v. Löwisede77f52006-07-03 13:01:35 +0000144- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
145 even if some data are received.
146
Martin v. Löwis45482392006-07-03 12:28:58 +0000147- Bug #1267547: Put proper recursive setup.py call into the
148 spec file generated by bdist_rpm.
149
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000150- Bug #1514693: Update turtle's heading when switching between
151 degrees and radians.
152
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000153- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000154 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000155
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000156- Bug #1514703: Only setup canvas window in turtle when the canvas
157 is created.
158
Martin v. Löwis7596e832006-07-01 15:33:37 +0000159- Bug #1513223: .close() of a _socketobj now releases the underlying
160 socket again, which then gets closed as it becomes unreferenced.
161
Fred Drake10497c82006-06-29 02:57:48 +0000162- Bug #1504333: Make sgmllib support angle brackets in quoted
163 attribute values.
164
165- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
166 sgmllib ('[' and ']' were not accepted).
167
Georg Brandl1be63af2006-06-28 20:23:25 +0000168- Fix a bug in the turtle module's end_fill function.
169
Brett Cannon53ab5b72006-06-22 16:49:14 +0000170- Bug #1510580: The 'warnings' module improperly required that a Warning
171 category be either a types.ClassType and a subclass of Warning. The proper
172 check is just that it is a subclass with Warning as the documentation states.
173
Georg Brandlad29e632006-06-21 17:45:17 +0000174- The compiler module now correctly compiles the new try-except-finally
175 statement (bug #1509132).
176
Neal Norwitz60373cd2006-06-22 06:30:50 +0000177- The wsgiref package is now installed properly on Unix.
178
Vinay Sajip28e57612006-07-01 10:45:20 +0000179- A bug was fixed in logging.config.fileConfig() which caused a crash on
180 shutdown when fileConfig() was called multiple times.
181
Gerhard Häring762fbd32006-07-02 17:48:30 +0000182- The sqlite3 module did cut off data from the SQLite database at the first
183 null character before sending it to a custom converter. This has been fixed
184 now.
185
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000186Extension Modules
187-----------------
188
Tim Peters112aad32006-07-19 00:03:19 +0000189- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
190 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
191 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000192
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000193- Assigning None to pointer type fields in ctypes structures possible
194 overwrote the wrong fields, this is fixed now.
195
196- Fixed a segfault in _ctypes when ctypes.wintypes were imported
197 on non-Windows platforms.
198
199- Bug #1518190: The ctypes.c_void_p constructor now accepts any
200 integer or long, without range checking.
201
202- Patch #1517790: It is now possible to use custom objects in the ctypes
203 foreign function argtypes sequence as long as they provide a from_param
204 method, no longer is it required that the object is a ctypes type.
205
206- The '_ctypes' extension module now works when Python is configured
207 with the --without-threads option.
208
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000209- Bug #1513646: os.access on Windows now correctly determines write
210 access, again.
211
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000212- Bug #1512695: cPickle.loads could crash if it was interrupted with
213 a KeyboardInterrupt.
214
Neal Norwitza12aa882006-07-06 06:45:08 +0000215- Bug #1296433: parsing XML with a non-default encoding and
216 a CharacterDataHandler could crash the interpreter in pyexpat.
217
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000218- Patch #1516912: improve Modules support for OpenVMS.
219
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000220Build
221-----
222
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000223- Automate Windows build process for the Win64 SSL module.
224
Tim Peters32a83612006-07-10 21:08:24 +0000225- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000226 Previously, the slight difference could cause compilation errors of the
227 'zlib' module on systems with more than one version of zlib.
228
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000229- The MSI compileall step was fixed to also support a TARGETDIR
230 with spaces in it.
231
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000232- Bug #1517388: sqlite3.dll is now installed on Windows independent
233 of Tcl/Tk.
234
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000235- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000236 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000238Tests
239-----
240
241- Call os.waitpid() at the end of tests that spawn child processes in order
242 to minimize resources (zombies).

245-------------
246
Nick Coghlan2d792252006-07-06 13:47:18 +0000247- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
248 documentation for the warnings module.
249

259Core and builtins
260-----------------
261
Georg Brandla56b9152006-06-19 06:35:54 +0000262- Patch #1507676: Error messages returned by invalid abstract object operations
263 (such as iterating over an integer) have been improved and now include the
264 type of the offending object to help with debugging.
265
Brett Cannonea3912b2006-06-13 21:46:41 +0000266- Bug #992017: A classic class that defined a __coerce__() method that returned
267 its arguments swapped would infinitely recurse and segfault the interpreter.
268
Neal Norwitz909eb122006-06-12 02:13:21 +0000269- Fix the socket tests so they can be run concurrently.
270
Neal Norwitzb9845e72006-06-12 02:11:18 +0000271- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000272 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000273
Brett Cannon22565aa2006-06-09 22:31:23 +0000274- Bug #532646: object.__call__() will continue looking for the __call__
275 attribute on objects until one without one is found. This leads to recursion
276 when you take a class and set its __call__ attribute to an instance of the
277 class. Originally fixed for classic classes, but this fix is for new-style.
278 Removes the infinite_rec_3 crasher.
279
Georg Brandl24250812006-06-09 18:45:48 +0000280- The string and unicode methods startswith() and endswith() now accept
281 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
282
Brett Cannonde3b0522006-06-08 17:00:45 +0000283- Buffer objects, at the C level, never used the char buffer
284 implementation even when the char buffer for the wrapped object was
285 explicitly requested (originally returned the read or write buffer).
286 Now a TypeError is raised if the char buffer is not present but is
287 requested.
288
Georg Brandlddbaa662006-06-04 21:56:52 +0000289- Patch #1346214: Statements like "if 0: suite" are now again optimized
290 away like they were in Python 2.4.
291
Georg Brandlb7c8f542006-05-27 12:30:25 +0000292- Builtin exceptions are now full-blown new-style classes instead of
293 instances pretending to be classes, which speeds up exception handling
294 by about 80% in comparison to 2.5a2.
295
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000296- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
297 Unicode 4.1.
298
Georg Brandlf4ef1162006-05-26 18:03:31 +0000299- Patch #921466: sys.path_importer_cache is now used to cache valid and
300 invalid file paths for the built-in import machinery which leads to
301 fewer open calls on startup.
302
Tim Peters696cf432006-05-24 21:10:40 +0000303- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
304 of-2 bases. The largest speedup is for inputs with about 1000 decimal
305 digits. Conversion from non-power-of-2 bases remains quadratic-time in
306 the number of input digits (it was and remains linear-time for bases
307 2, 4, 8, 16 and 32).
308
Tim Petersb713ec22006-05-23 18:45:30 +0000309- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
310 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
311 an integer close to ``sys.maxint``. This was repaired by patch
312 #1335972, which also gives a nice speedup.
313
Richard Jonescebbefc2006-05-23 18:28:17 +0000314- Patch #1337051: reduced size of frame objects.
315
316- PyErr_NewException now accepts a tuple of base classes as its
317 "base" parameter.
318
Richard Jones7c88dcc2006-05-23 10:37:38 +0000319- Patch #876206: function call speedup by retaining allocated frame
320 objects.
321
Georg Brandl7b90e162006-05-18 07:01:27 +0000322- Bug #1462152: file() now checks more thoroughly for invalid mode
323 strings and removes a possible "U" before passing the mode to the
324 C library function.
325
Neal Norwitz1004a532006-05-15 07:17:23 +0000326- Patch #1488312, Fix memory alignment problem on SPARC in unicode
327
Neal Norwitz373f0a72006-05-15 07:04:36 +0000328- Bug #1487966: Fix SystemError with conditional expression in assignment
329
Martin v. Löwis879768d2006-05-11 13:28:43 +0000330- WindowsError now has two error code attributes: errno, which carries
331 the error values from errno.h, and winerror, which carries the error
332 values from winerror.h. Previous versions put the winerror.h values
333 (from GetLastError()) into the errno attribute.
334
Martin v. Löwis77736712006-05-04 05:51:03 +0000335- Patch #1475845: Raise IndentationError for unexpected indent.
336
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000337- Patch #1479181: split open() and file() from being aliases for each other.
338
Tim Peters44bd9862006-06-01 13:49:23 +0000339- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
340 methods were always silently ignored by dictionaries when comparing keys.
341 They are now passed through (except when using the C API function
342 ``PyDict_GetItem()``, whose semantics did not change).
343
344- Bug #1456209: In some obscure cases it was possible for a class with a
345 custom ``__eq__()`` method to confuse dict internals when class instances
346 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
347 No, you don't have any code that did this ;-)

353
354- Patch #1462338: Upgrade pyexpat to expat 2.0.0
355
Brett Cannon6ee7d012006-06-08 16:23:04 +0000356- Change binascii.hexlify to accept a read-only buffer instead of only a char
357 buffer and actually follow its documentation.
358
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000359- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
360
Nick Coghlanc649ec52006-05-29 12:43:05 +0000361- Patch #1478788 (modified version): The functional extension module has
362 been renamed to _functools and a functools Python wrapper module added.
363 This provides a home for additional function related utilities that are
364 not specifically about functional programming. See PEP 309.
365
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000366- Patch #1493701: performance enhancements for struct module.
367
Georg Brandl378d5922006-05-17 14:26:50 +0000368- Patch #1490224: time.altzone is now set correctly on Cygwin.
369
Georg Brandl8d3342b2006-05-16 07:38:27 +0000370- Patch #1435422: zlib's compress and decompress objects now have a
371 copy() method.
372
Andrew MacIntyre92913322006-06-13 15:04:24 +0000373- Patch #1454481: thread stack size is now tunable at runtime for thread
374 enabled builds on Windows and systems with Posix threads support.
375
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000376- On Win32, os.listdir now supports arbitrarily-long Unicode path names
377 (up to the system limit of 32K characters).
378
379- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
380 As a result, these functions now raise WindowsError instead of OSError.
381
Tim Peters7a822da2006-05-25 21:50:17 +0000382- ``time.clock()`` on Win64 should use the high-performance Windows
383 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
384 Windows platforms).
385
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000386- Calling Tk_Init twice is refused if the first call failed as that
387 may deadlock.
388
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000389- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
390 accept it without potentially using an uninitialized pointer.
391
392- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
393 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
394 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000395
Gregory P. Smith372b5832006-06-05 18:48:21 +0000396- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000397 [pybsddb project SF patch number 1466734]
398
Gregory P. Smith372b5832006-06-05 18:48:21 +0000399- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
400 parameter is supplied. [SF pybsddb bug #1477863]
401
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000402- bsddb: the __len__ method of a DB object has been fixed to return correct
403 results. It could previously incorrectly return 0 in some cases.
404 Fixes SF bug 1493322 (pybsddb bug 1184012).
405
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000406- bsddb: the bsddb.dbtables Modify method now raises the proper error and
407 aborts the db transaction safely when a modifier callback fails.
408 Fixes SF python patch/bug #1408584.
409
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000410- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000411 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000412 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
413 database calls that would previously deadlock. [SF python bug #775414]
414
Vinay Sajip28e57612006-07-01 10:45:20 +0000415- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000416
Walter Dörwald4994d952006-06-19 08:07:50 +0000417- Patch #1506645: add Python wrappers for the curses functions
418 is_term_resized, resize_term and resizeterm.

424 functions.
425
Martin v. Löwis3798da02006-06-17 18:44:27 +0000426- Patch #812986: Update turtle output even if not tracing.
427
Vinay Sajip28e57612006-07-01 10:45:20 +0000428- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000429 Tkinter.BaseWidget.
430
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000431- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
432
Martin v. Löwis337487e2006-06-17 09:15:14 +0000433- Patch #763580: Add name and value arguments to Tkinter variable
434 classes.
435
Georg Brandl83cc0d02006-06-14 08:50:03 +0000436- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
437 mime.types file for determining MIME types.
438
Georg Brandl2605ca82006-06-14 06:08:31 +0000439- Bug #1339007: Shelf objects now don't raise an exception in their
440 __del__ method when initialization failed.
441
Martin v. Löwisd8251432006-06-14 05:21:04 +0000442- Patch #1455898: The MBCS codec now supports the incremental mode for
443 double-byte encodings.
444
Tim Peters43898b42006-06-14 04:09:25 +0000445- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
446 guarantee that adjacent triples in the return list always describe
447 non-adjacent blocks. Previously, a pair of matching blocks could end
448 up being described by multiple adjacent triples that formed a partition
449 of the matching pair.
450
Greg Ward0e0c9f42006-06-11 16:24:11 +0000451- Bug #1498146: fix optparse to handle Unicode strings in option help,
452 description, and epilog.
453
Greg Wardd1c797e2006-06-11 14:42:41 +0000454- Bug #1366250: minor optparse documentation error.
455
Greg Ward7f547402006-06-11 00:40:49 +0000456- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
457 clarify docs.
458
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000459- The wsgiref package has been added to the standard library.
460
Nick Coghlan676725d2006-06-08 13:54:49 +0000461- The functions update_wrapper() and wraps() have been added to the functools
462 module. These make it easier to copy relevant metadata from the original
463 function when writing wrapper functions.
464
Tim Petersd6a9eef2006-06-05 01:48:21 +0000465- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
466 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000467
Martin v. Löwis3f767792006-06-04 19:36:28 +0000468- Patch #1359618: Speed up charmap encoder by using a trie structure
469 for lookup.
470
Tim Petersd609b1a2006-06-02 23:22:51 +0000471- The functions in the ``pprint`` module now sort dictionaries by key
472 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
473 if and only if its display required more than one line, although that
474 wasn't documented. The new behavior increases predictability; e.g.,
475 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
476
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000477- Patch #1497027: try HTTP digest auth before basic auth in urllib2
478 (thanks for J. J. Lee).
479
Georg Brandl2b330372006-05-28 20:23:12 +0000480- Patch #1496206: improve urllib2 handling of passwords with respect to
481 default HTTP and HTTPS ports.
482
George Yoshidaf3c65de2006-05-28 16:39:09 +0000483- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
484
Bob Ippolito7298f272006-05-23 18:43:47 +0000485- Patch #1281707: speed up gzip.readline.
486
Georg Brandlb89316f2006-05-17 15:51:16 +0000487- Patch #1180296: Two new functions were added to the locale module:
488 format_string() to get the effect of "format % items" but locale-aware,
489 and currency() to format a monetary number with currency sign.
490
Georg Brandle3a25832006-05-17 14:56:04 +0000491- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
492 and several features added, such as speed and geometry control.
493
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000494- Patch #1488881: add support for external file objects in bz2 compressed
495 tarfiles.
496
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000497- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
498 stdout arguments, making it possible to redirect input and output
499 for remote debugging.
500
501- Patch #1484695: Update the tarfile module to version 0.8. This fixes
502 a couple of issues, notably handling of long file names using the
503 GNU LONGNAME extension.
504
505- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
506 new flag when ``name`` is already the name of an option flag.
507
508- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
509 package.
510
511- Patch #1472854: make the rlcompleter.Completer class usable on non-
512 UNIX platforms.
513
514- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
515
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000516- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000547What's New in Python 2.5 alpha 2?
548=================================
549
550*Release date: 27-APR-2006*
551
552Core and builtins
553-----------------
554
Thomas Heller1b046642006-04-18 18:51:06 +0000555- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
556 by converting these apis from macros into exported functions again:
557
558 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
559 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
560 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
561 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
562 PyRun_String Py_CompileString
563
Martin v. Löwis45294a92006-04-18 06:24:08 +0000564- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
565
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000566- All uses of PyStructSequence_InitType have been changed to initialize
567 the type objects only once, even if the interpreter is initialized
568 multiple times.
569
Neal Norwitz61546162006-04-14 05:20:28 +0000570- Bug #1454485, array.array('u') could crash the interpreter. This was
571 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
572 to unicode when it didn't make sense. 'u#' now requires a unicode string.
573
574- Py_UNICODE is unsigned. It was always documented as unsigned, but
575 due to a bug had a signed value in previous versions.
576
Tim Peters3a5e8b12006-04-11 01:44:07 +0000577- Patch #837242: ``id()`` of any Python object always gives a positive
578 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
579 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000580 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000581 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000582
Tim Peters3a5e8b12006-04-11 01:44:07 +0000583 def __hash__(self):
584 return id(self) # WRONG
585
586 because a hash result must be a (short) Python int but it was always
587 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000588 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000589 was always usable as a hash value before this patch. That's no longer
590 necessarily so.
591
592- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000593 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000594 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000595 #1454844)
596
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000597- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
598 involving generators that have paused outside of any ``try`` or ``with``
599 blocks. (In 2.5a1, a paused generator that was part of a reference
600 cycle could not be garbage collected, regardless of whether it was
601 paused in a ``try`` or ``with`` block.)

610 fails with an error condition.
611
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000612- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
613
614- Bug #1117761: bsddb.*open() no longer raises an exception when using
615 the cachesize parameter.
616
617- Bug #1149413: bsddb.*open() no longer raises an exception when using
618 a temporary db (file=None) with the 'n' flag to truncate on open.
619
620- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
621 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000622
Armin Rigoa9017c32006-04-19 11:50:27 +0000623- Patch #1062014: AF_UNIX sockets under Linux have a special
624 abstract namespace that is now fully supported.

627-------
628
Peter Astrand7d1d4362006-07-14 14:04:45 +0000629- Bug #1223937: subprocess.CalledProcessError reports the exit status
630 of the process using the returncode attribute, instead of
631 abusing errno.
632
Tim Peters711bf302006-04-25 03:31:36 +0000633- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
634 a doctest to be skipped (the code is not run, and the expected output
635 or exception is ignored).
636
Nick Coghlanda2268f2006-04-24 04:37:15 +0000637- Fixed contextlib.nested to cope with exceptions being raised and
638 caught inside exit handlers.
639
Greg Wardab05edc2006-04-23 03:47:58 +0000640- Updated optparse module to Optik 1.5.1 (allow numeric constants in
641 hex, octal, or binary; add ``append_const`` action; keep going if
642 gettext cannot be imported; added ``OptionParser.destroy()`` method;
643 added ``epilog`` for better help generation).
644
Tim Peters21fbd572006-04-21 21:18:10 +0000645- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
646 called from a thread spawned as a side effect of importing a module.
647
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000648- The pydoc module now supports documenting packages contained in
649 .zip or .egg files.
650
651- The pkgutil module now has several new utility functions, such
652 as ``walk_packages()`` to support working with packages that are either
653 in the filesystem or zip files.
654
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000655- The mailbox module can now modify and delete messages from
656 mailboxes, in addition to simply reading them. Thanks to Gregory
657 K. Johnson for writing the code, and to the 2005 Google Summer of
658 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000659
Tim Petersc7605f22006-04-17 21:12:33 +0000660- The ``__del__`` method of class ``local`` in module ``_threading_local``
661 returned before accomplishing any of its intended cleanup.
662

668
Anthony Baxtere29002c2006-04-12 12:07:31 +0000669- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
670 Windows. Bug #1469163.
671
Phillip J. Eby47032112006-04-11 01:07:43 +0000672- The warnings, linecache, inspect, traceback, site, and doctest modules
673 were updated to work correctly with modules imported from zipfiles or
674 via other PEP 302 __loader__ objects.
675
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000676- Patch #1467770: Reduce usage of subprocess._active to processes which
677 the application hasn't waited on.
678
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000679- Patch #1462222: Fix Tix.Grid.
680
Neal Norwitza31bf182006-04-09 03:35:43 +0000681- Fix exception when doing glob.glob('anything*/')
682
Skip Montanaro262fb922006-04-21 02:31:07 +0000683- The pstats.Stats class accepts an optional stream keyword argument to
684 direct output to an alternate file-like object.
685
Anthony Baxter51bcb682006-04-05 14:51:42 +0000686Build
687-----
688
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000689- The Makefile now has a reindent target, which runs reindent.py on
690 the library.
691
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000692- Patch #1470875: Building Python with MS Free Compiler
693
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000694- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000695
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000696- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
697 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000698 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000699 CXX from --with-cxx-main, see description in README.
700
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000701- Patch #1429775: Link extension modules with the shared libpython.
702
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000703- Fixed a libffi build problem on MIPS systems.
704
Tim Peters8931ff12006-05-13 23:28:20 +0000705- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
706 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
707 and "%zu" for unsigned integers of type ``size_t``.
708
Anthony Baxter51bcb682006-04-05 14:51:42 +0000709Tests
710-----
711
Nick Coghlanda2268f2006-04-24 04:37:15 +0000712- test_contextlib now checks contextlib.nested can cope with exceptions
713 being raised and caught inside exit handlers.
714
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000715- test_cmd_line now checks operation of the -m and -c command switches
716
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000717- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
718 it separately and by hand. It also wasn't cleaning up its changes to
719 the current Decimal context.
720
Thomas Woutersabd08882006-04-26 15:53:30 +0000721- regrtest.py now has a -M option to run tests that test the new limits of
722 containers, on 64-bit architectures. Running these tests is only sensible
723 on 64-bit machines with more than two gigabytes of memory. The argument
724 passed is the maximum amount of memory for the tests to use.
725
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000726Tools
727-----
728
729- Added the Python benchmark suite pybench to the Tools/ directory;
730 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000732Documentation
733-------------
734
Tim Petersb06d28c2006-05-12 01:57:59 +0000735- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
736
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000737- PEP 343: Added Context Types section to the library reference
738 and attempted to bring other PEP 343 related documentation into
739 line with the implementation and/or python-dev discussions.
740
Tim Peters8dc73d22006-04-24 02:03:16 +0000741- Bug #1337990: clarified that ``doctest`` does not support examples
742 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000745What's New in Python 2.5 alpha 1?
746=================================
747
Anthony Baxterebed3f62006-04-03 15:03:44 +0000748*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000749
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000750Core and builtins
751-----------------
752
Nick Coghlan43832302006-04-23 17:04:07 +0000753- PEP 338: -m command line switch now delegates to runpy.run_module
754 allowing it to support modules in packages and zipfiles
755
Martin v. Löwisc661b882006-04-20 04:54:23 +0000756- On Windows, .DLL is not an accepted file name extension for
757 extension modules anymore; extensions are only found if they
758 end in .PYD.
759
Martin v. Löwisea62d252006-04-03 10:56:49 +0000760- Bug #1421664: sys.stderr.encoding is now set to the same value as
761 sys.stdout.encoding.
762
Neal Norwitz92e212f2006-04-03 04:48:37 +0000763- __import__ accepts keyword arguments.
764
Georg Brandlccadf842006-03-31 18:54:53 +0000765- Patch #1460496: round() now accepts keyword arguments.
766
Anthony Baxter262c00a2006-03-30 10:53:17 +0000767- Fixed bug #1459029 - unicode reprs were double-escaped.
768
Hye-Shik Changd478f342006-03-23 12:32:36 +0000769- Patch #1396919: The system scope threads are reenabled on FreeBSD
770 5.4 and later versions.
771
Neal Norwitze98ccf62006-03-23 05:39:47 +0000772- Bug #1115379: Compiling a Unicode string with an encoding declaration
773 now gives a SyntaxError.
774
Georg Brandlabd1ff82006-03-18 07:59:59 +0000775- Previously, Python code had no easy way to access the contents of a
776 cell object. Now, a ``cell_contents`` attribute has been added
777 (closes patch #1170323).
778
Tim Peterscf79aac2006-03-16 01:14:46 +0000779- Patch #1123430: Python's small-object allocator now returns an arena to
780 the system ``free()`` when all memory within an arena becomes unused
781 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
782 freed. Some applications will see a drop in virtual memory size now,
783 especially long-running applications that, from time to time, temporarily
784 use a large number of small objects. Note that when Python returns an
785 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000786 platform C library will in turn return that memory to the operating system.
787 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000788 appears to be effective at least on Microsoft C and gcc-based systems.
789 Thanks to Evan Jones for hard work and patience.
790
Georg Brandl533ff6f2006-03-08 18:09:27 +0000791- Patch #1434038: property() now uses the getter's docstring if there is
792 no "doc" argument given. This makes it possible to legitimately use
793 property() as a decorator to produce a read-only property.
794
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000795- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
796 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
797 of requiring an int or long in slicing and a few other contexts, enabling
798 other objects (e.g. Numeric Python's integers) to be used as slice indices.
799
Neal Norwitz995acdf2006-03-07 05:01:00 +0000800- Fixed various bugs reported by Coverity's Prevent tool.
801
Brett Cannonbf364092006-03-01 04:25:17 +0000802- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
803 new exception base class, BaseException, which has a new message attribute.
804 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
805 Raising a string exception now raises a DeprecationWarning.
806
Thomas Woutersfb609f42006-02-28 16:37:25 +0000807- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
808 explicitly relative, using 'from .module import name' to mean 'from the same
809 package as this module is in. Imports without dots still default to the
810 old relative-then-absolute, unless 'from __future__ import
811 absolute_import' is used.
812
Brett Cannona7446e32006-02-27 23:39:10 +0000813- Properly check if 'warnings' raises an exception (usually when a filter set
814 to "error" is triggered) when raising a warning for raising string
815 exceptions.
816
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000817- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000818 The name was removed from Include/code.h.
819
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000820- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000821
Guido van Rossum1968ad32006-02-25 22:38:04 +0000822- Patch 1433928:
823 - The copy module now "copies" function objects (as atomic objects).
824 - dict.__getitem__ now looks for a __missing__ hook before raising
825 KeyError.
826
Tim Peters84ef21c2006-02-28 20:39:06 +0000827- PEP 343: with statement implemented. Needs ``from __future__ import
828 with_statement``. Use of 'with' as a variable will generate a warning.
829 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000830 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000831 The following objects have __context__ methods:
832 - The built-in file type.
833 - The thread.LockType type.
834 - The following types defined by the threading module:
835 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
836 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000837
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000838- Fix the encodings package codec search function to only search
839 inside its own package. Fixes problem reported in patch #1433198.
840
841 Note: Codec packages should implement and register their own
842 codec search function. PEP 100 has the details.
843
Tim Peters9ea89d22006-06-04 03:26:02 +0000844- PEP 353: Using ``Py_ssize_t`` as the index type.
845
846- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
847 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
848 now allow Python to make use of memory blocks exceeding 2**32 bytes for
849 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
850 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000851
Neal Norwitzfc76d632006-01-10 06:03:13 +0000852- Patch #1400181, fix unicode string formatting to not use the locale.
853 This is how string objects work. u'%f' could use , instead of .
854 for the decimal point. Now both strings and unicode always use periods.
855
Neal Norwitz671b9e32006-01-09 07:07:12 +0000856- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
857 configure would break checking curses.h.
858
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000859- Bug #959576: The pwd module is now builtin. This allows Python to be
860 built on UNIX platforms without $HOME set.
861
Neal Norwitzc10978f2005-12-19 06:07:16 +0000862- Bug #1072182, fix some potential problems if characters are signed.
863
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000864- Bug #889500, fix line number on SyntaxWarning for global declarations.
865
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000866- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
867
Neal Norwitze7214a12005-12-18 05:03:17 +0000868- Support for converting hex strings to floats no longer works.
869 This was not portable. float('0x3') now raises a ValueError.
870
Barry Warsaw2a38a862005-12-18 01:27:35 +0000871- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000872 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000873 is now displayed in interactive prompt banner.
874
Georg Brandlfa166682005-12-17 21:45:17 +0000875- Implementation of PEP 341 - Unification of try/except and try/finally.
876 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000877 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000878
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000879- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
880 now encodes backslash correctly.
881
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000882- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
883
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000884- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000885 and long longs.
886
Neal Norwitz67715f02005-11-09 06:59:35 +0000887- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000888 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000889 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000890
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000891- Replaced most Unicode charmap codecs with new ones using the
892 new Unicode translate string feature in the builtin charmap
893 codec; the codecs were created from the mapping tables available
894 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
895 encodings now include a mapping for the Apple logo)
896
Tim Peterse3547fd2005-12-16 23:13:57 +0000897- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000898
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000899- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000900
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000901- A new AST parser implementation was completed. The abstract
902 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000903 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000904
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000905- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000906 The following code now raises a SyntaxError: foo(a = i for i in range(10))
907
Neal Norwitz708e51a2005-10-03 04:48:15 +0000908- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
909
Neal Norwitz11bd1192005-10-03 00:54:56 +0000910- SF Bug #887946: fix segfault when redirecting stdin from a directory.
911 Provide a warning when a directory is passed on the command line.
912
Neal Norwitz40d37812005-10-02 01:48:49 +0000913- Fix segfault with invalid coding.
914
915- SF bug #772896: unknown encoding results in MemoryError.
916
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000917- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000918 supported a __len__() method which evaluated to False when the iterator
919 was empty.
920
Guido van Rossum630db602005-09-20 18:49:54 +0000921- On 64-bit platforms, when __len__() returns a value that cannot be
922 represented as a C int, raise OverflowError.
923
Skip Montanarof8948ca2005-09-19 03:54:46 +0000924- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000925 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000926
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000927- SF bug #893549: parsing keyword arguments was broken with a few format
928 codes.
929
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000930- Changes donated by Elemental Security to make it work on AIX 5.3
931 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
932 bug #105470: test_pwd fails on 64bit system (Opteron).
933
Guido van Rossum539c6622005-09-14 17:49:54 +0000934- Changes donated by Elemental Security to make it work on HP-UX 11 on
935 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
936
Georg Brandl4550b8d2005-08-26 06:43:52 +0000937- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000938 (fixes bug #1119418).
939
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000940- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
941
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000942- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
943 exceptions that cause a function to exit.
944
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000945- The implementation of set() and frozenset() was revised to use its
946 own internal data structure. Memory consumption is reduced by 1/3
947 and there are modest speed-ups as well. The API is unchanged.
948
Tim Petersde7990b2005-07-17 23:45:23 +0000949- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
950
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000951- SF bug #1229429: PyObject_CallMethod failed to decrement some
952 reference counts in some error exit cases.
953
Tim Petersecc6e6a2005-07-10 22:30:55 +0000954- SF bug #1185883: Python's small-object memory allocator took over
955 a block managed by the platform C library whenever a realloc specified
956 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000957 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000958 portable way to copy data from the C-managed block into Python's
959 small-object space without risking a memory fault. Python's small-object
960 realloc now leaves such blocks under the control of the platform C
961 realloc.
962
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000963- SF bug #1232517: An overflow error was not detected properly when
964 attempting to convert a large float to an int in os.utime().
965
Raymond Hettinger3296e692005-06-29 23:29:56 +0000966- SF bug #1224347: hex longs now print with lowercase letters just
967 like their int counterparts.
968
Michael W. Hudson188d4362005-06-20 16:52:57 +0000969- SF bug #1163563: the original fix for bug #1010677 ("thread Module
970 Breaks PyGILState_Ensure()") broke badly in the case of multiple
971 interpreter states; back out that fix and do a better job (see
972 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
973 for a longer write-up of the problem).
974
Michael W. Hudsondf888462005-06-03 14:41:55 +0000975- SF patch #1180995: marshal now uses a binary format by default when
976 serializing floats.
977
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000978- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
979 the routines that promise to produce IEEE 754 binary representations
980 of floats now simply copy bytes around.
981
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000982- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
983 278.
984
Brett Cannonc3647ac2005-04-26 03:45:26 +0000985- patch #1109424: int, long, float, complex, and unicode now check for the
986 proper magic slot for type conversions when subclassed. Previously the
987 magic slot was ignored during conversion. Semantics now match the way
988 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000989 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000990 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000991 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000992
Barry Warsawc8d907c2005-04-19 23:43:40 +0000993- Descriptors defined in C with a PyGetSetDef structure, where the setter is
994 NULL, now raise an AttributeError when attempting to set or delete the
995 attribute. Previously a TypeError was raised, but this was inconsistent
996 with the equivalent pure-Python implementation.
997
Michael W. Hudson774479c2005-04-18 08:46:17 +0000998- It is now safe to call PyGILState_Release() before
999 PyEval_InitThreads() (note that if there is reason to believe there
1000 are multiple threads around you still must call PyEval_InitThreads()
1001 before using the Python API; this fix is for extension modules that
1002 have no way of knowing if Python is multi-threaded yet).
1003
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001004- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1005 disabled caused a crash.
1006
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001007- Bug #1165306: instancemethod_new allowed the creation of a method
1008 with im_class == im_self == NULL, which caused a crash when called.
1009
Tim Petersecc6e6a2005-07-10 22:30:55 +00001010- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001011 fixes the crash seen in bug #1165761
1012
Raymond Hettinger96229b12005-03-11 06:49:40 +00001013- Added two new builtins, any() and all().
1014
Brett Cannon409d8f22005-03-05 06:47:57 +00001015- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001016 (e.g., ``class C(): pass`` is no longer a syntax error).
1017 Patch #1176012 added support to the 'parser' module and 'compiler' package
1018 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001019
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001020- Patch #1115086: Support PY_LONGLONG in structmember.
1021
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001022- Bug #1155938: new style classes did not check that __init__() was
1023 returning None.
1024
Tim Petersecc6e6a2005-07-10 22:30:55 +00001025- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001026 ('\') with a specific error message.
1027
Martin v. Löwisff232d72005-03-03 09:24:38 +00001028- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1029
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001030- Bug #1124295: the __name__ attribute of file objects was
1031 inadvertently made inaccessible in restricted mode.
1032
Tim Petersecc6e6a2005-07-10 22:30:55 +00001033- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001034 an ferror() call.
1035
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001036- min() and max() now support key= arguments with the same meaning as in
1037 list.sort().
1038
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001039- The peephole optimizer now performs simple constant folding in expressions:
1040 (2+3) --> (5).
1041
Raymond Hettingera422c342005-01-11 03:03:27 +00001042- set and frozenset objects can now be marshalled. SF #1098985.
1043
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001044- Bug #1077106: Poor argument checking could cause memory corruption
1045 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001046
Jeremy Hyltonab630502005-02-04 18:44:06 +00001047- The parser did not complain about future statements in illegal
1048 positions. It once again reports a syntax error if a future
1049 statement occurs after anything other than a doc string.
1050
Neil Schemenauercf52c072005-08-12 17:34:58 +00001051- Change the %s format specifier for str objects so that it returns a
1052 unicode instance if the argument is not an instance of basestring and
1053 calling __str__ on the argument returns a unicode instance.
1054
Tim Petersf4e69282006-02-27 17:15:31 +00001055- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1056 current thread state when the auto-GIL-state machinery knows about
1057 it (since the thread state is being deleted, continuing to remember it
1058 can't help, but can hurt if another thread happens to get created with
1059 the same thread id).
1060
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001061Extension Modules

1078
1079- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1080
1081- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001082 is deprecated. The undocumented re.engine variable no longer exists.
1083

1085 SS2 (single-shift 2) escape sequences correctly.
1086
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001087- The unicodedata module was updated to the 4.1 version of the Unicode
1088 database. The 3.2 version is still available as unicodedata.db_3_2_0
1089 for applications that require this specific version (such as IDNA).
1090
Neal Norwitzb62c4332006-03-04 18:35:47 +00001091- The timing module is no longer built by default. It was deprecated
1092 in PEP 4 in Python 2.0 or earlier.
1093
Guido van Rossum1968ad32006-02-25 22:38:04 +00001094- Patch 1433928: Added a new type, defaultdict, to the collections module.
1095 This uses the new __missing__ hook behavior added to dict (see above).
1096
Georg Brandldbd83392006-02-20 09:42:33 +00001097- Bug #854823: socketmodule now builds on Sun platforms even when
1098 INET_ADDRSTRLEN is not defined.
1099
Georg Brandlf4f44152006-02-18 22:29:33 +00001100- Patch #1393157: os.startfile() now has an optional argument to specify
1101 a "command verb" to invoke on the file.
1102
Neal Norwitz082b2df2006-02-07 07:04:46 +00001103- Bug #876637, prevent stack corruption when socket descriptor
1104 is larger than FD_SETSIZE.
1105
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001106- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1107 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1108 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1109
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001110- Patch #1422385: The nis module now supports access to domains other
1111 than the system default domain.
1112
Martin v. Löwis14694662006-02-03 12:54:16 +00001113- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1114 are reported, the limit on path name lengths is removed, and stat reports
1115 WindowsError now (instead of OSError).
1116
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001117- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001191- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1192 the request code argument, which results in more C-like behaviour
1193 for large or negative values.
1194
Tim Petersecc6e6a2005-07-10 22:30:55 +00001195- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1204 available on the platform.
1205
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001206- Bug #1166660: The readline module could segfault if hook functions
1207 were set in a different thread than that which called readline.
1208
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00001209- collections.deque objects now support a remove() method.
1210
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001211- operator.itemgetter() and operator.attrgetter() now support retrieving
1212 multiple fields. This provides direct support for sorting on multiple
1213 keys (primary, secondary, etc).
1214
Martin v. Löwisb60ae992005-03-08 09:10:29 +00001215- os.access now supports Unicode path names on non-Win32 systems.

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001235- the cPickle module no longer accepts the deprecated None option in the
1236 args tuple returned by __reduce__().
1237
Raymond Hettingerb2594052004-12-05 09:25:51 +00001238- itertools.islice() now accepts None for the start and step arguments.
1239 This allows islice() to work more readily with slices:
1240 islice(s.start, s.stop, s.step)
1241
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001242- datetime.datetime() now has a strptime class method which can be used to

Tim Peters112aad32006-07-19 00:03:19 +00001250
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001251- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1252 been renamed to have only a single underscore prefix. This was done to
1253 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001254
Nick Coghlan43832302006-04-23 17:04:07 +00001255- PEP 338: new module runpy defines a run_module function to support
1256 executing modules which provide access to source code or a code object
1257 via the PEP 302 import mechanisms.
1258
Anthony Baxter93f5b932006-04-03 08:05:07 +00001259- The email module's parsedate_tz function now sets the daylight savings
1260 flag to -1 (unknown) since it can't tell from the date whether it should

1267 in attribute values.
1268
Anthony Baxterc51ee692006-04-01 00:57:31 +00001269- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001270 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001271 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001272 module will not be built.
1273
Tim Petersc17976e2006-04-01 00:26:53 +00001274- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1275 aren't officially supported here, and trying to use them will probably
1276 raise an exception some day. But dicts have been allowed, and "mostly
1277 worked", so support for them won't go away without warning.
1278
Georg Brandl338ef7d2006-03-31 18:42:16 +00001279- Bug #1445068: getpass.getpass() can now be given an explicit stream
1280 argument to specify where to write the prompt.
1281
Georg Brandl22ec80b2006-03-31 18:25:44 +00001282- Patch #1462313, bug #1443328: the pickle modules now can handle classes
1283 that have __private names in their __slots__.
1284

1288 key to be used for signing the uploaded code.
1289
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001290- Queue.Queue objects now support .task_done() and .join() methods
1291 to make it easier to monitor when daemon threads have completed
1292 processing all enqueued tasks. Patch #1455676.
1293
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001294- popen2.Popen objects now preserve the command in a .cmd attribute.
1295

1297
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001298- email 4.0 package now integrated. This is largely the same as the email 3.0
1299 package that was included in Python 2.3, except that PEP 8 module names are
1300 now used (e.g. mail.message instead of email.Message). The MIME classes
1301 have been moved to a subpackage (e.g. email.mime.text instead of
1302 email.MIMEText). The old names are still supported for now. Several
1303 deprecated Message methods have been removed and lots of bugs have been
1304 fixed. More details can be found in the email package documentation.
1305
Walter Dörwald40108c92006-03-27 08:15:44 +00001306- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1307 (a subclass of tuple) that provides incremental decoders and encoders
1308 (a way to use stateful codecs without the stream API). Python functions
1309 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1310 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1311 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001312
Walter Dörwald067db482006-03-15 22:17:27 +00001313- Patch #1359365: Calling next() on a closed StringIO.String object raises
1314 a ValueError instead of a StopIteration now (like file and cString.String do).
1315 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1316 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001317
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001318- A regrtest option -w was added to re-run failed tests in verbose mode.

1324 grew an optional 'generation' argument.
1325
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001326- A library msilib to generate Windows Installer files, and a distutils
1327 command bdist_msi have been added.
1328
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001329- PEP 343: new module contextlib.py defines decorator @contextmanager
1330 and helpful context managers nested() and closing().
1331
Martin v. Löwis415ed932006-02-27 19:56:30 +00001332- The compiler package now supports future imports after the module docstring.
1333
Georg Brandl8f7c54e2006-02-20 08:40:38 +00001334- Bug #1413790: zipfile now sanitizes absolute archive names that are
1335 not allowed by the specs.
1336
Georg Brandlc98eeed2006-02-19 14:57:47 +00001337- Patch #1215184: FileInput now can be given an opening hook which can

Tim Peterse3547fd2005-12-16 23:13:57 +00001390 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1391 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1392 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1393 Ronald L. Rivest offered this advice for Python:
1394
1395 "The consensus of researchers in this area (at least as
1396 expressed at the NIST Hash Function Workshop 10/31/05),
1397 is that SHA-256 is a good choice for the time being, but
1398 that research should continue, and other alternatives may
1399 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001400
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001401- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00001446
Georg Brandlb9256022005-08-24 18:46:39 +00001447- Patch #1062060: urllib.urlretrieve() now raises a new exception, named

1452
Martin v. Löwis56066d22005-08-24 07:38:12 +00001453- Bug #1178484: Return complete lines from codec stream readers
1454 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001455 correct line numbers for decoding errors in source code.

1470
Georg Brandla4a8b822005-07-15 09:13:21 +00001471- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1472 parameter, but uses the usual "kwargs=None".
1473
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001474- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001475 Patch #1209527 (Contributed by Connelly).
1476
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001477- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1478 to W3C name (404 -> 'Not Found'). RFE #1216944.
1479
Georg Brandl9e43acf2005-07-04 17:16:07 +00001480- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1481 as this can cause problems with apps closing all file descriptors.
1482
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001483- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001484 it can be missing in embedded interpreters

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001493- The tokenize module now detects and reports indentation errors.
1494 Bug #1224621.
1495
Raymond Hettinger68c04532005-06-10 11:05:19 +00001496- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001497 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001498 the generate_tokens() function now accepts a callable argument that
1499 terminates by raising StopIteration.
1500
Georg Brandl9166e1a2005-06-04 09:20:03 +00001501- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1504 component of the path.
1505
Skip Montanaro174dd222005-05-14 20:54:16 +00001506- Patch #1120353: The xmlrpclib module provides better, more transparent,
1507 support for datetime.{datetime,date,time} objects. With use_datetime set
1508 to True, applications shouldn't have to fiddle with the DateTime wrapper
1509 class at all.
1510
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001511- distutils.commands.upload was added to support uploading distribution

1515 them to PyPI.
1516
Raymond Hettinger267b8682005-03-27 10:47:39 +00001517- decimal operator and comparison methods now return NotImplemented
1518 instead of raising a TypeError when interacting with other types. This
1519 allows other classes to implement __radd__ style methods and have them
1520 work as expected.
1521
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001522- Bug #1163325: Decimal infinities failed to hash. Attempting to
1523 hash a NaN raised an InvalidOperation instead of a TypeError.
1524
Tim Petersecc6e6a2005-07-10 22:30:55 +00001525- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1559
Guido van Rossumd0641422005-02-03 15:01:24 +00001560- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1561 disables recursive traversal through instance attributes, which can
1562 be exploited in various ways.
1563
Tim Peterse3547fd2005-12-16 23:13:57 +00001564- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001565 flags on the HTTP listening socket.
1566
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001567- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1568 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1569
Tim Peterse3547fd2005-12-16 23:13:57 +00001570- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001571 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1572
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001573- Bug #1110478: Revert os.environ.update to do putenv again.
1574
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001575- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1576
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001577- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1578
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001579- Enhancements to the csv module:
1580
1581 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001582 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001583 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001584 + Dialect parameter parsing has been re-implemented to improve error
1585 reporting.
1586 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1587 dictates.
1588 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001589 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001590 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001591 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1592 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001593 + reader now allows \r characters to be quoted (previously it only allowed
1594 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001595 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001596 + Dialect classes passed to the module are no longer instantiated by
1597 the module before being parsed (the former validation scheme required
1598 this, but the mechanism was unreliable).
1599 + The dialect registry now contains instances of the internal
1600 C-coded dialect type, rather than references to python objects.
1601 + the internal c-coded dialect type is now immutable.
1602 + register_dialect now accepts the same keyword dialect specifications
1603 as the reader and writer, allowing the user to register dialects
1604 without first creating a dialect class.
1605 + a configurable limit to the size of parsed fields has been added -
1606 previously, an unmatched quote character could result in the entire
1607 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001608 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001609 the parser field size limit (returning the former limit). The initial
1610 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001611 + A line_num attribute has been added to the reader object, which tracks
1612 the number of lines read from the source iterator. This is not
1613 the same as the number of records returned, as records can span
1614 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001615 + reader and writer objects were not being registered with the cyclic-GC.
1616 This has been fixed.
1617
Brett Cannone6539c42005-01-08 02:43:53 +00001618- _DummyThread objects in the threading module now delete self.__block that is
1619 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1620 lock primitives tend to be limited in number and thus should not be wasted on
1621 a _DummyThread object. Fixes bug #1089632.
1622
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001623- The imghdr module now detects Exif files.
1624
Raymond Hettinger6065d322004-12-20 23:51:53 +00001625- StringIO.truncate() now correctly adjusts the size attribute.
1626 (Bug #951915).
1627
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001628- locale.py now uses an updated locale alias table (built using
1629 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1630 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001631 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001632
Raymond Hettinger3557f422004-12-07 12:02:02 +00001633- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1634
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001635- the pickle module no longer accepts the deprecated None option in the
1636 args tuple returned by __reduce__().
1637
Brett Cannon84667c02004-12-07 03:25:18 +00001638- optparse now optionally imports gettext. This allows its use in setup.py.
1639
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001640- the pickle module no longer uses the deprecated bin parameter.
1641
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001642- the shelve module no longer uses the deprecated binary parameter.
1643
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001644- the pstats module no longer uses the deprecated ignore() method.
1645
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001646- the filecmp module no longer uses the deprecated use_statcache argument.
1647
Raymond Hettinger664347b2004-12-04 21:21:53 +00001648- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1649 extended or overridden by subclasses. Formerly, the subclassed method would
1650 be ignored by the rest of the module. (Bug #1078905).
1651
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001652- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001653 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001654
Walter Dörwald36733692004-12-22 12:50:50 +00001655- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1656 once when a size argument is given. This prevents a buffer overflow in the
1657 tokenizer with very long source lines.
1658
Barry Warsaw538561e2006-01-01 21:48:54 +00001659- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1660 immediately after creating the object, without any intervening
1661 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001662
Skip Montanaro05885812005-01-16 20:48:27 +00001663- The reconvert.quote function can now emit triple-quoted strings. The
1664 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001665
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001666- ``UserString.MutableString`` now supports negative indices in
1667 ``__setitem__`` and ``__delitem__``
1668
Greg Ward40407942005-03-05 02:53:17 +00001669- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1670 correctly.
1671
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001672- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1673 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1674 character even if the user has passed a size parameter to get a proper
1675 line ending. Remove the special handling of a "\r\n" that has been split
1676 between two lines.
1677
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001678- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1679 about illegal code points. The codec now supports PEP 293 style error
1680 handlers.
1681
Walter Dörwald78a78b02005-09-01 12:04:29 +00001682- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001683 from the input stream, so that the output is a byte string in the correct
1684 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001685
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001686- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1687 considering it exactly like a '*'.
1688
Walter Dörwald007f8df2005-10-09 19:42:27 +00001689- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1690 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001691
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001692- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1693
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001694- Patch #1413711: Certain patterns of differences were making difflib
1695 touch the recursion limit.
1696
Walter Dörwald58917a62006-03-31 15:26:22 +00001697- Bug #947906: An object oriented interface has been added to the calendar
1698 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001699 called as a script (e.g. via ``python -mcalendar``). Localized month and
1700 weekday names can be ouput (even if an exotic encoding is used) using
1701 special classes that use unicode.

1710
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001711- Build support for Win64-AMD64 was added.
1712
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001713- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1714
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001715- Patch #881820: look for openpty and forkpty also in libbsd.
1716
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001717- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1718 The zlib module is now builtin on Windows.
1719
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001720- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1721
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001722- Bug #1189330: configure did not correctly determine the necessary
1723 value of LINKCC if python was built with GCC 4.0.
1724
Trent Mick8321b422005-07-26 02:29:21 +00001725- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1726 vulnerability in zlib 1.2.1 and 1.2.2.
1727
Brett Cannon08cd5982005-04-24 22:26:38 +00001728- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1729 flags that change binary compatibility. Changes were also made to
1730 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001731 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001732
Bob Ippolitoed233462005-03-29 13:47:59 +00001733- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1734 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1735 no longer exists). This configure patch makes things right.
1736
Martin v. Löwise2713be2005-03-08 15:03:08 +00001737- Bug #1158607: Build with --disable-unicode again.
1738
Brett Cannon46d96232005-02-16 00:07:19 +00001739- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1740 defined. Discovered as a result of not being able to build on OS X.
1741
Brett Cannon516592f2004-12-07 00:42:59 +00001742- setup.py now uses the directories specified in LDFLAGS using the -L option
1743 and in CPPFLAGS using the -I option for adding library and include
1744 directories, respectively, for compiling extension modules against. This has
1745 led to the core being compiled using the values in CPPFLAGS. It also removes
1746 the need for the special-casing of both DarwinPorts and Fink for darwin since
1747 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1748 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1749 Fink, ``-I/opt/local/include`` for DarwinPorts).
1750
Brett Cannon43802422005-02-10 20:48:03 +00001751- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1752 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1753 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1754 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001756C API
1757-----
1758
Tim Petersc9d78aa2006-03-26 23:27:58 +00001759- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1760 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1761 is obtained via the ``PyObject_`` family, it must be released via the
1762 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1763 always been officially true, but when Python's small-object allocator was
1764 introduced, an attempt was made to cater to a few extension modules
1765 discovered at the time that obtained memory via ``PyObject_New`` but
1766 released it via ``PyMem_DEL``. It's years later, and if such code still
1767 exists it will fail now (probably with segfaults, but calling wrong
1768 low-level memory management functions can yield many symptoms).
1769
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001770- Added a C API for set and frozenset objects.
1771
Raymond Hettinger66517482004-12-03 11:45:13 +00001772- Removed PyRange_New().
1773
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001774- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1775 mapping argument now. This string is used as a mapping table. Byte values
1776 greater than the length of the string and 0xFFFE are treated as undefined
1777 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001783- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001784
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001785- Patch #1276356: New resource "urlfetch" is implemented. This enables
1786 even impatient people to run tests that require remote files.
