10Core and Builtins
11-----------------
12
Antoine Pitrouaeb6cee2010-11-04 20:30:33 +000013- Issue #10293: Remove obsolete field in the PyMemoryView structure,
14 unused undocumented value PyBUF_SHADOW, and strangely-looking code in
15 PyMemoryView_GetContiguous.
16
Eric Smith27bbca62010-11-04 17:06:58 +000017- Issue #6081: Add str.format_map, similar to str.format(**mapping).
18
Benjamin Petersonbbb04122010-10-30 23:16:28 +000019- If FileIO.__init__ fails, close the file descriptor.
20
Raymond Hettingerdd421542010-10-30 08:10:29 +000021- Issue #10221: dict.pop(k) now has a key error message that includes the
22 missing key (same message d[k] returns for missing keys).
23
Antoine Pitrou07e20ef2010-10-28 22:56:58 +000024- Issue #5437: A preallocated MemoryError instance should not hold traceback
25 data (including local variables caught in the stack trace) alive infinitely.

28 of the offending line.
29
Antoine Pitrou9583cac2010-10-21 13:42:28 +000030- Issue #10089: Add support for arbitrary -X options on the command-line.
31 They can be retrieved through a new attribute ``sys._xoptions``.
32
Victor Stinnerf933e1a2010-10-20 22:58:25 +000033- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead
34 of the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
35 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
36 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
37 encoding and to encode command line arguments on this OS.
38
Victor Stinner4c7c8c32010-10-16 13:14:10 +000039- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects

47 its value as the default 512 when compiling on AIX.
48
Victor Stinnerf3170cc2010-10-15 12:04:23 +000049- Use locale encoding instead of UTF-8 to encode and decode filenames if
50 Py_FileSystemDefaultEncoding is not set.
51
Victor Stinner22a351a2010-10-14 12:04:34 +000052- Issue #10095: fp_setreadl() doesn't reopen the file, reuse instead the file
53 descriptor.
54
Georg Brandl66c221e2010-10-14 07:04:07 +000055- Issue #9418: Moved private string methods ``_formatter_parser`` and
56 ``_formatter_field_name_split`` into a new ``_string`` module.

70 and a new method send_message to send an email.message.Message object.
71
Éric Araujoa5633922010-11-08 17:13:03 +000072- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
73 handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
74 code directory name contains a non-ASCII character and the locale encoding is
75 ASCII.
76
Victor Stinner64bc3b22010-11-07 15:47:36 +000077- Issue #10329: The trace module writes reports using the input Python script

Éric Araujo89c04782010-11-05 23:58:34 +000089- Issue #10252: Close file objects in a timely manner in distutils code and
90 tests. Patch by Brian Brazil, completed by Éric Araujo.
91
Antoine Pitrou243757e2010-11-05 21:15:39 +000092- Issue #10180: Pickling file objects is now explicitly forbidden, since
93 unpickling them produced nonsensical results.
94
Antoine Pitrou39a65912010-11-05 19:47:27 +000095- Issue #10311: The signal module now restores errno before returning from

108
Phillip J. Ebya01799f2010-11-03 00:46:45 +0000109- wsgiref now implements and validates PEP 3333, rather than an experimental
110 extension of PEP 333. (Note: earlier versions of Python 3.x may have
111 incorrectly validated some non-compliant applications as WSGI compliant;
112 if your app validates with Python <3.2b1+, but not on this version, it is
113 likely the case that your app was not compliant.)
114

340Core and Builtins
341-----------------
342
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +0000343- Issue #10068: Global objects which have reference cycles with their module's
344 dict are now cleared again. This causes issue #7140 to appear again.
345
Victor Stinner257d38f2010-10-09 10:12:11 +0000346- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +0000347 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +0000348
Georg Brandl27a28582010-10-10 09:49:21 +0000349- ast.literal_eval() can now handle negative numbers. It is also a little more
350 liberal in what it accepts without compromising the safety of the evaluation.
351 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +0000352
Benjamin Peterson970d1882010-10-02 17:55:47 +0000353- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
354 result metaclasses can now be ABCs (see #9533).
355
Victor Stinneraef57e32010-10-02 11:50:49 +0000356- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
357
Victor Stinner5593d8a2010-10-02 11:11:27 +0000358- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +0000359 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
360 32 bits wchar_t (eg. Linux in narrow build).

371 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +0000372
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000373- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +0000374 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +0000376- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
377
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000378- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
379 threads are still running. Instead, reinitialize the GIL on a second call to
380 Py_Initialize().
381
Georg Brandl27a28582010-10-10 09:49:21 +0000382- All SyntaxErrors now have a column offset and therefore a caret when the error
383 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +0000384
Brett Cannonbc2eff32010-09-19 21:39:02 +0000385- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
386 module that was imported, but instead gets the module from sys.modules.
387
Georg Brandl27a28582010-10-10 09:49:21 +0000388- Issue #9212: The range type_items now provides index() and count() methods, to
389 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +0000390
Georg Brandl27a28582010-10-10 09:49:21 +0000391- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
392 with a non-empty format string. This is an effort to future-proof user
393 code. If a derived class does not currently implement __format__ but later
394 adds its own __format__, it would most likely break user code that had
395 supplied a format string. This will be changed to a DeprecationWaring in
396 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +0000397
Antoine Pitrou1df15362010-09-13 14:16:46 +0000398- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
399 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
400 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
401
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000402- Issue #9210: Configure option --with-wctype-functions was removed. Using the
403 functions from the libc caused the methods .upper() and lower() to become
404 locale aware and created subtly wrong results.
405
Georg Brandl27a28582010-10-10 09:49:21 +0000406- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
407 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000408
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000409- Issue #4617: Previously it was illegal to delete a name from the local
410 namespace if it occurs as a free variable in a nested block. This limitation
411 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
412
Georg Brandl27a28582010-10-10 09:49:21 +0000413- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
414 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
415 Also, the "backslashreplace" error handler now joins surrogate pairs into a
416 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +0000417
Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000418- Issue #9757: memoryview objects get a release() method to release the
419 underlying buffer (previously this was only done when deallocating the
420 memoryview), and gain support for the context management protocol.
421
Antoine Pitrou079ce542010-09-08 12:37:10 +0000422- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
423 thread-local storage key.

447
Éric Araujo6108bf52010-10-04 23:52:37 +0000448- Issue #9042: Fix interaction of custom translation classes and caching in
449 gettext.
450
Éric Araujoef777bd2010-10-05 00:04:20 +0000451- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000452 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000453 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000454 replacement for old handle_accept() and avoids the user to call accept()
455 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000478- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +0000479 retry the select() loop instead of bailing out. This is because select() can
480 incorrectly report a socket as ready for reading (for example, if it received
481 some data with an invalid checksum).

Raymond Hettingerdc08a142010-09-12 05:15:22 +0000560
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000561- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000562 it possible for the user to create self-referencing ordered dictionaries which
563 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000564 approach of using weakref proxies so that reference cycles never get created
565 in the first place.
566
Victor Stinnercb043522010-09-10 23:49:04 +0000567- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
568 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +0000569 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +0000570
Georg Brandl27a28582010-10-10 09:49:21 +0000571- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
572 environment variable to set the filesystem encoding at Python startup.
573 sys.setfilesystemencoding() creates inconsistencies because it is unable to
574 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +0000575
Georg Brandl27a28582010-10-10 09:49:21 +0000576- Issue #9410: Various optimizations to the pickle module, leading to speedups
577 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
578 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000579
Georg Brandl27a28582010-10-10 09:49:21 +0000580- The pprint module now supports printing OrderedDicts in their given order
581 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +0000583- Logging: Added QueueHandler class to facilitate logging usage with
584 multiprocessing.
585
Georg Brandl27a28582010-10-10 09:49:21 +0000586- Issue #9707: Rewritten reference implementation of threading.local which is
587 friendlier towards reference cycles. This change is not normally visible
588 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +0000589
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000590- Issue #6394: os.getppid() is now supported on Windows. Note that it will
591 still return the id of the parent process after it has exited. This process
592 id may even have been reused by another unrelated process.
593
Georg Brandl27a28582010-10-10 09:49:21 +0000594- Issue #9792: In case of connection failure, socket.create_connection() would
595 swallow the exception and raise a new one, making it impossible to fetch the
596 original errno, or to filter timeout errors. Now the original error is
597 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +0000608 * Update the seed() method to use all of the bits in a string instead of just
609 the hash value. This makes better use of the seed value and assures the
610 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000611
Georg Brandl27a28582010-10-10 09:49:21 +0000612 * Improved the random()-->integer algorithm used in choice(), shuffle(),
613 sample(), randrange(), and randint(). Formerly, it used int(n*random())
614 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000615
616 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +0000621- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
622 cases now also have assertWarns and assertWarnsRegexp methods to check that a
623 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +0000624
Georg Brandl27a28582010-10-10 09:49:21 +0000625- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of

Gregory P. Smith13b55292010-09-06 08:30:23 +0000635- hashlib has two new constant attributes: algorithms_guaranteed and
636 algorithms_avaiable that respectively list the names of hash algorithms
637 guaranteed to exist in all Python implementations and the names of hash
638 algorithms available in the current process.
639

767 return characters from the full Unicode range, even on narrow unicode builds
768 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
769 in Python is that unicodedata.numeric() now returns the correct value for
770 large code points, and repr() may consider more characters as printable.
771
Victor Stinner6c00c142010-08-17 23:37:11 +0000772- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Ezio Melotti57221d02010-07-01 07:32:02 +00001144- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001145 start byte and the continuation byte(s) are now considered invalid, instead of
1146 the number of bytes specified by the start byte. E.g.:
1147 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1148 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1149 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1150 returned a single u'\ufffd'.

1153 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00001164- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
1165 dealing with unary minus applied to a constant. The removed code was mutating
1166 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00001167
Victor Stinner554f3f02010-06-16 23:33:54 +00001168- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00001169 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00001170 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001171 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00001172
Victor Stinner25e8ec42010-06-25 00:02:38 +00001173- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
1174 "w*" format instead. Add tests for "w*" format.
1175
Victor Stinner06e49dd2010-06-13 18:21:50 +00001176- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00001177 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00001178 string formats.
1179
Georg Brandl62069d32010-07-31 08:56:11 +00001180- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001181 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1182 location of the raised exception.
1183
Victor Stinner313a1202010-06-11 23:56:51 +00001184- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1185 filenames and enable os.fsencode().
1186
Benjamin Peterson285a6892010-06-22 19:21:52 +00001187- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
1188
Georg Brandl62069d32010-07-31 08:56:11 +00001189- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
1190 interpreter with characters outside the Basic Multilingual Plane (higher than
1191 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00001192
Georg Brandl62069d32010-07-31 08:56:11 +00001193- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1194 TypeError instead of giving a DeprecationWarning when a float is parsed using
1195 the 'L' code (for long long). (All other integer codes already raise
1196 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001197
Victor Stinner600d3be2010-06-10 12:00:55 +00001198- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1199 enable shortcuts for upper case encoding name. Add also a shortcut for
1200 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1201
Georg Brandl62069d32010-07-31 08:56:11 +00001202- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1203 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001204
1205- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001206 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001207 like bytearray.
1208
Georg Brandl62069d32010-07-31 08:56:11 +00001209- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001210 used anymore and it was never documented.
1211
Georg Brandl62069d32010-07-31 08:56:11 +00001212- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00001213
Georg Brandl62069d32010-07-31 08:56:11 +00001214- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
1215 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001216
Georg Brandl62069d32010-07-31 08:56:11 +00001217- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1218 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1219 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1220 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001221
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001222- Issue #8748: Fix two issues with comparisons between complex and integer
1223 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001224 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1225 (2) The comparison raised an OverflowError for large integers, leading to
1226 unpredictable exceptions when combining integers and complex objects in sets
1227 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001228
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001229- Issue #8766: Initialize _warnings module before importing the first module.
1230 Fix a crash if an empty directory called "encodings" exists in sys.path.
1231
Victor Stinner9ca9c252010-05-19 16:53:30 +00001232- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001233 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001234 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001235
Georg Brandl62069d32010-07-31 08:56:11 +00001236- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1237 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001238
Victor Stinnerae6265f2010-05-15 16:27:27 +00001239- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1240 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001241 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001242 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001243
Victor Stinner59e62db2010-05-15 13:14:32 +00001244- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001245 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001246
Victor Stinnerb744ba12010-05-15 12:27:16 +00001247- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001248 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001249 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1250
Victor Stinner0964ee12010-04-30 16:48:45 +00001251- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001252 PyUnicode_FromString() to support surrogates in the filename and use the right
1253 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00001255- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
1256
Georg Brandl62069d32010-07-31 08:56:11 +00001257- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00001258
Benjamin Petersonfb886362010-04-24 18:21:17 +00001259- Issue #8419: Prevent the dict constructor from accepting non-string keyword
1260 arguments.
1261
Victor Stinner14284c22010-04-23 12:02:30 +00001262- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00001263 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00001357 where the right hand operand is a set of constants, by turning the set into a
1358 frozenset and pre-building it as a constant. The comparison operation is made
1359 against the constant instead of building a new set each time it is executed (a
1360 similar optimization already existed which turned a list of constants into a
1361 pre-built tuple). Patch and additional tests by Dave Malcolm.

1557 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1558 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001559 to match the behaviour of the other integer format codes.

1588 gives improved memory leak detection when running under Valgrind, while taking
1589 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00001666 applications that use a lot of regular expressions and limits the impact of
1667 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00001964- Issue #8524: When creating an SSL socket, the timeout value of the original
1965 socket wasn't retained (instead, a socket with a positive timeout would be
1966 turned into a non-blocking SSL socket).

Antoine Pitroud3f8ab82010-04-24 21:26:44 +00001968- Issue #5103: SSL handshake would ignore the socket timeout and block
1969 indefinitely if the other end didn't respond.
1970
Georg Brandl62069d32010-07-31 08:56:11 +00001971- The do_handshake() method of SSL objects now adjusts the blocking mode of the
1972 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00001983- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
1984 string "python" as the *ident*. openlog() arguments are all optional and
1985 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00001986
Georg Brandl62069d32010-07-31 08:56:11 +00001987- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
1988 non-infinite timeout. Also make that method friendlier with applications

2025
Victor Stinner0e59cc32010-04-16 23:49:32 +00002026- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

2038
Georg Brandl62069d32010-07-31 08:56:11 +00002039- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002040 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00002041 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002042
Victor Stinner485fb562010-04-13 11:07:24 +00002043- Issue #8383: pickle and pickletools use surrogatepass error handler when

Georg Brandl62069d32010-07-31 08:56:11 +00002062 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2063 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00002064
Raymond Hettingerc50846a2010-04-05 18:56:31 +00002065- Add functools.total_ordering() and functools.cmp_to_key().
2066
Georg Brandl62069d32010-07-31 08:56:11 +00002067- Issue #8257: The Decimal construct now accepts a float instance directly,
2068 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00002069
2070 >>> Decimal(1.1)
2071 Decimal('1.100000000000000088817841970012523233890533447265625')
2072
Georg Brandl62069d32010-07-31 08:56:11 +00002073- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2074 directly.

Georg Brandl62069d32010-07-31 08:56:11 +00002076- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2077 InvalidOperation instead of returning False. (Comparisons involving a quiet
2078 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2079 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002080
Georg Brandl62069d32010-07-31 08:56:11 +00002081- Issue #2531: Comparison operations between floats and Decimal instances now
2082 return a result based on the numeric values of the operands; previously they
2083 returned an arbitrary result based on the relative ordering of id(float) and
2084 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2085 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002086
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002087- Added a subtract() method to collections.Counter().
2088
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002089- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002090 argument `-` which tells it to read files to compile from stdin. Each line is
2091 read on demand and the named file is compiled immediately. (Original patch by
2092 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002093
Florent Xicluna806d8cf2010-03-30 19:34:18 +00002094- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2095 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00002096 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00002098- Comparisons using one of <, <=, >, >= between a complex instance and a
2099 Fractions instance now raise TypeError instead of returning True/False. This
2100 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2101 <=> complex, and complex <=> complex comparisons.

2109
Antoine Pitrou910bd512010-03-22 20:11:09 +00002110- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002111 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00002144- The internals of the subprocess module on POSIX systems have been replaced by
2145 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2146 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00002147
Georg Brandl62069d32010-07-31 08:56:11 +00002148- subprocess.Popen now has restore_signals and start_new_session features. The
2149 default of restore_signals=True is a new behavior compared to earlier Python
2150 versions. This means that signals such as SIGPIPE are not ignored by default
2151 in subprocesses launched by Python (Issue #1652).

Antoine Pitrou434736a2009-11-10 18:46:01 +00002427- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00002428 default when instantiating a `threading.RLock` object. This makes recursive
2429 locks as fast as regular non-recursive locks (previously, they were slower by
2430 10x to 15x).

2450 from stdin so that existing input does not confuse it and lead to incorrect
2451 entry or an IOError. It also properly flushes it afterwards to avoid the
2452 terminal echoing the input afterwards on OSes such as Solaris.

Georg Brandl62069d32010-07-31 08:56:11 +00002645 compared to other unix systems. In particular, os.getgroups() does not reflect

2674 Prior to this change, timezone adjustment in utctimetuple() could produce
2675 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00002678- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
2679 directive. When the ``%z`` directive is present in the format string, an
2680 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2681 ``datetime.timezone`` instance constructed from the parsed offset. If both
2682 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2683 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002685- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002686 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2687 ``datetime.timezone``, return fixed name and UTC offset from their
2688 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2689 returns ``None``. A class attribute, ``utc`` contains an instance
2690 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00003015 runtest_inner in regrtest, with warnings if the called test modifies them, and

3161Core and Builtins
3162-----------------
3163
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00003164- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
3165 of the command line.
3166
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00003167- Issue #6012: Add cleanup support to O& argument parsing.
3168
Eric Smith41669ca2009-05-23 14:23:22 +00003169- Issue #6089: Fixed str.format with certain invalid field specifiers
3170 that would raise SystemError.
3171
Raymond Hettinger2bcde142009-05-29 04:52:27 +00003172- Issue #5982: staticmethod and classmethod now expose the wrapped
3173 function with __func__.
3174
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00003175- Added support for multiple context managers in the same with-statement.
3176 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00003177
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00003178- Issue #5829: complex("1e500") no longer raises OverflowError. This
3179 makes it consistent with float("1e500") and interpretation of real
3180 and imaginary literals.
3181
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00003182- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
3183
R. David Murraydd226ea2009-05-13 12:27:21 +00003184- Issue #5994: the marshal module now has docstrings.
3185
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00003186- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
3187 (1) inf and nan strings with trailing whitespace were incorrectly
3188 rejected; (2) parsing of strings representing infinities and nans
3189 was locale aware; and (3) the interpretation of fromhex('-nan')
3190 didn't match that of float('-nan').

3193-------
3194
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00003195- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
3196
R. David Murrayfb123912009-05-28 18:19:00 +00003197- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
3198
R. David Murray1f1b9d32009-05-27 20:56:59 +00003199- Issue #6121: pydoc now ignores leading and trailing spaces in the
3200 argument to the 'help' function.
3201
Georg Brandlfaf41492009-05-26 18:31:11 +00003202- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
3203 arguments for strings with a space in them.
3204
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00003205- collections.namedtuple() was not working with the following field
3206 names: cls, self, tuple, itemgetter, and property.
3207
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00003208- In unittest, using a skipping decorator on a class is now equivalent to
3209 skipping every test on the class. The ClassTestSuite class has been removed.
3210
Martin v. Löwis70ccd162009-05-24 19:47:22 +00003211- Issue #6050: Don't fail extracting a directory from a zipfile if
3212 the directory already exists.
3213
Antoine Pitrou61f77b52009-05-24 15:46:13 +00003214- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
3215 than an int, which makes some operations possible under 64-bit Linux (e.g.
3216 DN_MULTISHOT with F_NOTIFY).
3217
Antoine Pitrou716c4442009-05-23 19:04:03 +00003218- Issue #5761: Add the name of the underlying file to the repr() of various
3219 IO objects.
3220
R. David Murraycaa27b72009-05-23 18:49:56 +00003221- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
3222 by Musashi Tamura, tests by Marcin Bachry.
3223
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00003224- Issue #1983: Fix functions taking or returning a process identifier to use
3225 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
3226 a process identifier type wider than the standard C integer type.
3227
R. David Murray87e20742009-05-23 01:30:26 +00003228- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
3229 Patch by Farhan Ahmad, test by Marcin Bachry.
3230
Antoine Pitrou6e610062009-05-15 17:04:50 +00003231- Issue #2116: Weak references and weak dictionaries now support copy()ing and
3232 deepcopy()ing.
3233
Antoine Pitrouc1d09362009-05-15 12:15:51 +00003234- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

Antoine Pitrou37d1c182009-05-14 21:54:00 +00003236- Issue #5918: Fix a crash in the parser module.
3237
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00003238- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
3239
Antoine Pitroue4501852009-05-14 18:55:55 +00003240- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
3241 library. This means, for example, that opening an UTF-16 text file in
3242 append mode doesn't add a BOM at the end of the file if the file isn't
3243 empty.
3244
R. David Murray74b89242009-05-13 17:33:03 +00003245- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
3246 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
3247 corrects a pydoc regression.
3248
Georg Brandl5f90d792010-08-01 22:31:05 +00003249- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00003250 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson932073a2009-05-23 16:14:33 +00003252Installation
3253------------
3254
3255- Issue #6047: fullinstall has been removed because Python 3's executable will
3256 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00003257
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00003258- Lib/smtpd.py is no longer installed as a script.

3268
Benjamin Peterson744af442009-05-23 18:51:49 +00003269- The _functools and _locale modules are now built into the libpython shared
3270 library instead of as extension modules.

3281
Georg Brandl5f90d792010-08-01 22:31:05 +00003282- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00003283 tests on darwin even when the OS was installed on a case-sensitive
3284 filesystem. Also fixed tests that should not be run when
3285 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00003288What's New in Python 3.1 beta 1?
3289================================
3290
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00003291*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00003292
3293Core and Builtins
3294-----------------
3295
Mark Dickinson865e01a2009-05-07 16:37:01 +00003296- Issue #5914: Add new C API function PyOS_string_to_double, and
3297 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3298
Eric Smith741191f2009-05-06 13:08:15 +00003299- Issue #3382: float.__format__, complex.__format__, and %-formatting
3300 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
3301 affects nan -> NAN and inf -> INF.
3302
Mark Hammond5a607a32009-05-06 08:04:54 +00003303- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
3304 in all operations, including splitdrive, split, etc. splitunc() now issues
3305 a PendingDeprecation warning.
3306
Eric Smith63376222009-05-05 14:04:18 +00003307- Issue #5920: For float.__format__, change the behavior with the
3308 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3309 to be like 'g' but with at least one decimal point and with a
3310 default precision of 12. Previously, the behavior the same but with
3311 a default precision of 6. This more closely matches str(), and
3312 reduces surprises when adding alignment flags to the empty
3313 presentation type. This also affects the new complex.__format__ in
3314 the same way.
3315
Martin v. Löwis011e8422009-05-05 04:43:17 +00003316- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
3317
R. David Murrayb18500d2009-05-04 22:59:07 +00003318- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3319 shadowed by classtype's, even if it was None. property now
3320 inserts the __doc__ into the subclass instance __dict__.
3321
Antoine Pitrou244651a2009-05-04 18:56:13 +00003322- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3323 sequences. Patch by Nick Barnes and Victor Stinner.
3324
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003325- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003326
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003327- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3328 received a new method, detach(). detach() disconnects the underlying stream
3329 from the buffer or text IO and returns it.
3330
Mark Dickinson33841c32009-05-01 15:37:04 +00003331- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3332 floats with absolute value over 1e50. Also remove length
3333 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3334 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003335
Eric Smith741191f2009-05-06 13:08:15 +00003336- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003337 format(complex(1, 2./3), '.5') now produces a sensible result.
3338
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003339- Issue #5864: Fix empty format code formatting for floats so that it
3340 never gives more than the requested number of significant digits.
3341
Eric Smith6dc46f52009-04-27 20:39:49 +00003342- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3343 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3344
Eric Smithcc32a112009-04-26 21:35:14 +00003345- Issue #5835: Deprecate PyOS_ascii_formatd.
3346
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003347- Issue #4971: Fix titlecase for characters that are their own
3348 titlecase, but not their own uppercase.
3349
Benjamin Peterson193152c2009-04-25 01:08:45 +00003350- Issue #5283: Setting __class__ in __del__ caused a segfault.
3351
Mark Dickinsonad476da2009-04-23 19:14:16 +00003352- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3353 z involves nans, infs or negative zeros.
3354
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003355- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003356
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003357- Issue #1869 (and many duplicates): make round(x, n) correctly
3358 rounded for a float x, by using the decimal <-> binary conversions
3359 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3360 consistently agrees with format(x, '.2f').
3361
Benjamin Petersonae937c02009-04-18 20:54:08 +00003362- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3363 some builtin types.
3364
Eric Smith0923d1d2009-04-16 20:16:10 +00003365- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3366
Eric Smith35e84722009-04-16 20:21:28 +00003367- Issue #5515: str.format() type 'n' combined with commas and leading
3368 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003369
3370- Implement PEP 378, Format Specifier for Thousands Separator, for
3371 floats.
3372
Mark Dickinson3370cce2009-04-17 22:40:53 +00003373- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003374 1e11, not 1e12. This avoids printing 13 significant digits in
3375 situations where only 12 of them are correct. Example problem
3376 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3377 long time.)
3378
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003379- Issue #1580: On most platforms, use a 'short' float repr: for a
3380 finite float x, repr(x) now outputs a string based on the shortest
3381 sequence of decimal digits that rounds to x. Previous behaviour was
3382 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003383 Another minor difference is that the new repr switches to
3384 exponential notation at 1e16 instead of the previous 1e17; this
3385 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003386
3387 There's a new sys attribute sys.float_repr_style, which takes
3388 the value 'short' to indicate that we're using short float repr,
3389 and 'legacy' if the short float repr isn't available for one
3390 reason or another.
3391
3392 The float repr change involves incorporating David Gay's 'perfect
3393 rounding' code into the Python core (it's in Python/dtoa.c). As a
3394 secondary consequence, all string-to-float and float-to-string
3395 conversions (including all float formatting operations) will be
3396 correctly rounded on these platforms.
3397
Georg Brandl5f90d792010-08-01 22:31:05 +00003398 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003399 this change does not apply.
3400
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003401- Issue #5759: float() didn't call __float__ on str subclasses.
3402
Georg Brandlabc38772009-04-12 15:51:51 +00003403- The string.maketrans() function is deprecated; there is a new static method
3404 maketrans() on the bytes and bytearray classes. This removes confusion about
3405 the types string.maketrans() is supposed to work with, and mirrors the
3406 methods available on the str class.
3407
R. David Murraydc6da8a2009-04-09 22:16:43 +00003408- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3409 its clarity and its speed.
3410
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003411- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003412 to avoid compiler warnings.
3413
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003414- Issue #3739: The unicode-internal encoder now reports the number of characters
3415 consumed like any other encoder (instead of the number of bytes).

3429
Raymond Hettingereb816952009-05-29 01:22:18 +00003430- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003737- Issue #4935: The overflow checking code in the expandtabs() method common
3738 to str, bytes and bytearray could be optimized away by the compiler, letting
3739 the interpreter segfault instead of raising an error.
3740
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003741- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3742 __next__ method.
3743
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003744- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3745 function no longer attempt to call the __long__ slot to convert an object
3746 to an integer. Only the __int__ and __trunc__ slots are examined.

3751
Antoine Pitrouab868312009-01-10 15:40:25 +00003752- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3753 common cases are optimized thanks to a dedicated fast path and a moderate
3754 amount of loop unrolling.
3755
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003756- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3757 collecting the oldest generation) so that allocating lots of objects without
3758 destroying them does not show quadratic performance. Based on a proposal by
3759 Martin von Löwis at
3760 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3761
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003762- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003763 having been closed (for instance, a read() call could return some
3764 previously buffered data). Patch by Dmitry Vasiliev.
3765
Antoine Pitrou05608432009-01-09 18:53:14 +00003766- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3767 flag to work properly. Furthermore, when specifying -u, the text stdout
3768 and stderr streams have line-by-line buffering enabled (the default being
3769 to buffer arbitrary chunks of data).
3770
Raymond Hettinger35631532009-01-09 03:58:09 +00003771- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3772 instead of ints (reducing its size from 4 to 8 times thereby reducing
3773 Python's overall memory).
3774
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003775- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3776 an existing .py counterpart, override the co_filename attributes of all
3777 code objects if the original filename is obsolete (which can happen if the
3778 file has been renamed, moved, or if it is accessed through different paths).
3779 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3780
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003781- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3782 one byte. Also fixes the meaning of len() so that it returns the number of
3783 items, rather than the size in bytes.
3784
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003785- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003787- Issue #4747: When the terminal does not use utf-8, executing a script with
3788 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3789
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003790- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

3794 did not get collected.
3795
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003796- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3797 where the tp_hash and tp_dict slots are both NULL.
3798
Georg Brandlccc47b62008-12-28 11:44:14 +00003799- Issue #4759: None is now allowed as the first argument of
3800 bytearray.translate(). It was always allowed for bytes.translate().
3801
Skip Montanaro80072cb2008-12-23 03:51:14 +00003802- Added test case to ensure attempts to read from a file opened for writing
3803 fail.
3804
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00003805- Issue #3106: Speedup some comparisons (str/str and int/int).

3809
Antoine Pitrou621601a2008-12-17 23:18:19 +00003810- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

3812 unreachable. Original patch by Neil Schemenauer.
3813

3815
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003816- Issue #2173: When getting device encoding, check that return value of
3817 nl_langinfo is not the empty string. This was causing silent build
3818 failures on OS X.
3819
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003820- Issue #4597: Fixed several opcodes that weren't always propagating
3821 exceptions.
3822
3823- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003824 context manager returns a value that cannot be converted to a bool.
3825
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003826- Issue #4445: Replace "sizeof(PyBytesObject)" with
3827 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3828 bytes instances. On a typical machine this saves 3 bytes of memory
3829 (on average) per allocation of a bytes instance.
3830
Christian Heimesa872de52008-12-05 08:26:55 +00003831- Issue #4533: File read operation was dreadfully slow due to a slowly
3832 growing read buffer. Fixed by using the same growth rate algorithm as
3833 Python 2.x.
3834
Antoine Pitrou5504e892008-12-06 21:27:53 +00003835- Issue #4509: Various issues surrounding resize of bytearray objects to
3836 which there are buffer exports (e.g. memoryview instances).
3837
Georg Brandlf9734072008-12-07 15:30:06 +00003838- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3839 method on file objects with closefd=False. The file descriptor is still
3840 kept open but the file object behaves like a closed file. The ``FileIO``
3841 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003842
Antoine Pitroubc420402008-12-07 20:14:49 +00003843- Issue #4569: Interpreter crash when mutating a memoryview with an item size
3844 larger than 1.

3849
Walter Dörwaldc1651a02009-05-03 22:55:55 +00003850- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3851 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3852 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3853 of using the replace error handler in PyUnicode_DecodeUTF8().

4174 do an explicit seek to the end of file (so that e.g. tell() returns the

4206 appropriately when it is being used via socket.makefile() objects
4207 rather than delaying the close by waiting for garbage collection to do it.
