Georg Brandl88b95f92012-05-06 11:24:06 +0200118 fields: st_ctime_ns, st_mtime_ns, and st_atime_ns, providing those times as an

635 suppressing the display of the chained exception context. The chained
636 context still remains available as the __context__ attribute.
637
Stefan Krah9a2d99e2012-02-25 12:24:21 +0100638- Issue #10181: New memoryview implementation fixes multiple ownership
639 and lifetime issues of dynamically allocated Py_buffer members (#9990)
640 as well as crashes (#8305, #7433). Many new features have been added
641 (See whatsnew/3.3), and the documentation has been updated extensively.
642 The ndarray test object from _testbuffer.c implements all aspects of
643 PEP-3118, so further development towards the complete implementation
644 of the PEP can proceed in a test-driven manner.
645
646 Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
647 and many ideas.

1214
Ned Deily99377482012-02-10 13:01:08 +01001215- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1216 Distutils-based packages with C extension modules may fail because
1217 Apple has removed gcc-4.2, the version used to build python.org
1218 64-bit/32-bit Pythons. If the user does not explicitly override
1219 the default C compiler by setting the CC environment variable,
1220 Distutils will now attempt to compile extension modules with clang
1221 if gcc-4.2 is required but not found. Also as a convenience, if
1222 the user does explicitly set CC, substitute its value as the default
1223 compiler in the Distutils LDSHARED configuration variable for OS X.
1224 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1225 SDK, neither of which are available in Xcode 4. This change does not
1226 attempt to override settings to support their use with Xcode 4.)

Ned Deily657b2de2011-06-28 19:51:30 -07001953- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1954 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1955 interpreter process. This could cause failures in non-Distutils subprocesses
1956 and was unreliable since tests or user programs could modify the interpreter
1957 environment after Distutils set it. Instead, have Distutils set the the
1958 deployment target only in the environment of each build subprocess. It is
1959 still possible to globally override the default by setting
1960 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1961 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001962 was built. Also, implement the same handling in packaging.

Nadeem Vawda3c01d162011-08-01 23:48:26 +02002779- Issue #11651: Improve the Makefile test targets to run more of the test suite
2780 more quickly. The --multiprocess option is now enabled by default, reducing
2781 the amount of time needed to run the tests. "make test" and "make quicktest"
2782 now include some resource-intensive tests, but no longer run the test suite
2783 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02002784 an easy platform-independent way to run test suite with sensible defaults.

Antoine Pitrouf83e4ac2011-07-29 23:57:10 +02002792- Issue #12626: In regrtest, allow to filter tests using a glob filter
2793 with the ``-m`` (or ``--match``) option. This works with all test cases
2794 using the unittest module. This is useful with long test suites

3093 files in binary mode, using the email package's binary support to parse

Steven Bethardb0270112011-01-24 21:02:50 +00003155
3156- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00003157 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Victor Stinnerf933e1a2010-10-20 22:58:25 +00003917 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00003918 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

3922 filenames encoded to the filesystem encoding with the surrogateescape error

4035 your app validates with Python <3.2b1+, but not on this version, it is likely
4036 the case that your app was not compliant.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00004300- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
4301 threads are still running. Instead, reinitialize the GIL on a second call to
4302 Py_Initialize().
4303
Georg Brandl27a28582010-10-10 09:49:21 +00004304- All SyntaxErrors now have a column offset and therefore a caret when the error
4305 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00004306
Brett Cannonbc2eff32010-09-19 21:39:02 +00004307- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
4308 module that was imported, but instead gets the module from sys.modules.
4309
Nick Coghlan37ee8502010-12-03 14:26:13 +00004310- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00004311 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00004313- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4314 with a non-empty format string. This is an effort to future-proof user
4315 code. If a derived class does not currently implement __format__ but later
4316 adds its own __format__, it would most likely break user code that had
4317 supplied a format string. This will be changed to a DeprecationWaring in
4318 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00004319
Antoine Pitrou1df15362010-09-13 14:16:46 +00004320- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
4321 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
4322 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
4323
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00004324- Issue #9210: Configure option --with-wctype-functions was removed. Using the
4325 functions from the libc caused the methods .upper() and lower() to become
4326 locale aware and created subtly wrong results.
4327
Georg Brandl27a28582010-10-10 09:49:21 +00004328- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
4329 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00004330
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00004331- Issue #4617: Previously it was illegal to delete a name from the local
4332 namespace if it occurs as a free variable in a nested block. This limitation
4333 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
4334
Georg Brandl27a28582010-10-10 09:49:21 +00004335- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
4336 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
4337 Also, the "backslashreplace" error handler now joins surrogate pairs into a
4338 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00004340- Issue #9757: memoryview objects get a release() method to release the
4341 underlying buffer (previously this was only done when deallocating the
4342 memoryview), and gain support for the context management protocol.
4343
Antoine Pitrou079ce542010-09-08 12:37:10 +00004344- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
4345 thread-local storage key.

4372
Éric Araujoef777bd2010-10-05 00:04:20 +00004373- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004374 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00004375 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004376 replacement for old handle_accept() and avoids the user to call accept()
4377 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00004379- Issue #9065: tarfile no longer uses "root" as the default for the uname and

4395 conforms to the philosophy of bytes and unicode separation in Python 3. A
4396 test suite has also been added.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00004400- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00004401 retry the select() loop instead of bailing out. This is because select() can
4402 incorrectly report a socket as ready for reading (for example, if it received
4403 some data with an invalid checksum).

Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00004405- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

4438 object, only munmap().
4439
Georg Brandl27a28582010-10-10 09:49:21 +00004440- logging: Changed LoggerAdapter implementation internally, to make it easier to
4441 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00004442
Vinay Sajipc84f0162010-09-21 11:25:39 +00004443- logging: hasHandlers method was added to Logger, and isEnabledFor,
4444 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
4445 LoggerAdapter was introduced into the unit tests for logging.

Florent Xiclunaeb19dce2010-09-18 23:34:07 +00004447- Issue #1686: Fix string.Template when overriding the pattern attribute.
4448
Antoine Pitrou98b46702010-09-18 22:59:00 +00004449- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00004450 non-blocking mode: they return None when an operation would block (instead of
4451 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00004452
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00004453- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
4454 another kind.

Georg Brandl27a28582010-10-10 09:49:21 +00004460- Issue #9854: The default read() implementation in io.RawIOBase now handles
4461 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00004462
Georg Brandl27a28582010-10-10 09:49:21 +00004463- Issue #1552: socket.socketpair() now returns regular socket.socket objects
4464 supporting the whole socket API (rather than the "raw" _socket.socket
4465 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00004466
Georg Brandl27a28582010-10-10 09:49:21 +00004467- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Éric Araujod8c73c62011-03-21 03:15:22 +01004470- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00004471 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00004477- Issue #9837: The read() method of ZipExtFile objects (as returned by

4479
Georg Brandl27a28582010-10-10 09:49:21 +00004480- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +00004482
Raymond Hettingerfa11db02010-09-12 04:12:42 +00004483- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00004484 it possible for the user to create self-referencing ordered dictionaries which
4485 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00004486 approach of using weakref proxies so that reference cycles never get created
4487 in the first place.
4488
Victor Stinnercb043522010-09-10 23:49:04 +00004489- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
4490 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00004491 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00004492
Georg Brandl27a28582010-10-10 09:49:21 +00004493- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
4494 environment variable to set the filesystem encoding at Python startup.
4495 sys.setfilesystemencoding() creates inconsistencies because it is unable to
4496 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00004497
Georg Brandl27a28582010-10-10 09:49:21 +00004498- Issue #9410: Various optimizations to the pickle module, leading to speedups
4499 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
4500 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00004501
Georg Brandl27a28582010-10-10 09:49:21 +00004502- The pprint module now supports printing OrderedDicts in their given order
4503 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00004504
Vinay Sajip121a1c42010-09-08 10:46:15 +00004505- Logging: Added QueueHandler class to facilitate logging usage with
4506 multiprocessing.
4507
Georg Brandl27a28582010-10-10 09:49:21 +00004508- Issue #9707: Rewritten reference implementation of threading.local which is
4509 friendlier towards reference cycles. This change is not normally visible
4510 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00004511
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00004512- Issue #6394: os.getppid() is now supported on Windows. Note that it will
4513 still return the id of the parent process after it has exited. This process
4514 id may even have been reused by another unrelated process.
4515
Georg Brandl27a28582010-10-10 09:49:21 +00004516- Issue #9792: In case of connection failure, socket.create_connection() would
4517 swallow the exception and raise a new one, making it impossible to fetch the
4518 original errno, or to filter timeout errors. Now the original error is
4519 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00004520
Georg Brandl27a28582010-10-10 09:49:21 +00004521- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
4522 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
4523 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00004525- Updates to the random module:
4526
Georg Brandl27a28582010-10-10 09:49:21 +00004527 * Document which parts of the module are guaranteed to stay the same across
4528 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00004529
Georg Brandl27a28582010-10-10 09:49:21 +00004530 * Update the seed() method to use all of the bits in a string instead of just
4531 the hash value. This makes better use of the seed value and assures the
4532 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00004533
Georg Brandl27a28582010-10-10 09:49:21 +00004534 * Improved the random()-->integer algorithm used in choice(), shuffle(),
4535 sample(), randrange(), and randint(). Formerly, it used int(n*random())
4536 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00004537
4538 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00004540- collections.OrderedDict now supports a new method for repositioning keys to
4541 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00004542
Georg Brandl27a28582010-10-10 09:49:21 +00004543- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test

4689 return characters from the full Unicode range, even on narrow unicode builds
4690 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
4691 in Python is that unicodedata.numeric() now returns the correct value for
4692 large code points, and repr() may consider more characters as printable.

4730 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00004731
4732 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

5071
Ezio Melotti57221d02010-07-01 07:32:02 +00005072- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00005073 start byte and the continuation byte(s) are now considered invalid, instead of
5074 the number of bytes specified by the start byte. E.g.:
5075 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
5076 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5077 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
5078 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00005079
Georg Brandl62069d32010-07-31 08:56:11 +00005080- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
5081 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

5093 dealing with unary minus applied to a constant. The removed code was mutating
5094 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00005095
Victor Stinner554f3f02010-06-16 23:33:54 +00005096- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00005097 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00005098 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00005099 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00005100
Victor Stinner25e8ec42010-06-25 00:02:38 +00005101- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
5102 "w*" format instead. Add tests for "w*" format.
5103
Victor Stinner06e49dd2010-06-13 18:21:50 +00005104- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00005105 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00005106 string formats.
5107
Georg Brandl62069d32010-07-31 08:56:11 +00005108- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00005109 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
5110 location of the raised exception.
5111
Victor Stinner313a1202010-06-11 23:56:51 +00005112- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
5113 filenames and enable os.fsencode().
5114
Benjamin Peterson285a6892010-06-22 19:21:52 +00005115- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
5116
Georg Brandl62069d32010-07-31 08:56:11 +00005117- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
5118 interpreter with characters outside the Basic Multilingual Plane (higher than
5119 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00005120
Georg Brandl62069d32010-07-31 08:56:11 +00005121- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
5122 TypeError instead of giving a DeprecationWarning when a float is parsed using
5123 the 'L' code (for long long). (All other integer codes already raise
5124 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00005125
Victor Stinner600d3be2010-06-10 12:00:55 +00005126- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
5127 enable shortcuts for upper case encoding name. Add also a shortcut for
5128 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
5129
Georg Brandl62069d32010-07-31 08:56:11 +00005130- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
5131 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005132
5133- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00005134 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005135 like bytearray.
5136
Georg Brandl62069d32010-07-31 08:56:11 +00005137- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00005138 used anymore and it was never documented.
5139
Georg Brandl62069d32010-07-31 08:56:11 +00005140- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00005141
Georg Brandl62069d32010-07-31 08:56:11 +00005142- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
5143 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00005144
Georg Brandl62069d32010-07-31 08:56:11 +00005145- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
5146 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
5147 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
5148 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00005149
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005150- Issue #8748: Fix two issues with comparisons between complex and integer
5151 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00005152 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
5153 (2) The comparison raised an OverflowError for large integers, leading to
5154 unpredictable exceptions when combining integers and complex objects in sets
5155 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005156
Victor Stinner7d79b8b2010-05-19 20:40:50 +00005157- Issue #8766: Initialize _warnings module before importing the first module.
5158 Fix a crash if an empty directory called "encodings" exists in sys.path.
5159
Victor Stinner9ca9c252010-05-19 16:53:30 +00005160- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00005161 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00005162 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00005163
Georg Brandl62069d32010-07-31 08:56:11 +00005164- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
5165 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00005166
Victor Stinnerae6265f2010-05-15 16:27:27 +00005167- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
5168 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00005169 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00005170 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00005171
Victor Stinner59e62db2010-05-15 13:14:32 +00005172- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00005173 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00005174
Victor Stinnerb744ba12010-05-15 12:27:16 +00005175- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00005176 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00005177 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
5178
Victor Stinner0964ee12010-04-30 16:48:45 +00005179- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00005180 PyUnicode_FromString() to support surrogates in the filename and use the right
5181 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00005182
Georg Brandl8569e582010-05-19 20:57:08 +00005183- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
5184
Georg Brandl62069d32010-07-31 08:56:11 +00005185- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00005186
Benjamin Petersonfb886362010-04-24 18:21:17 +00005187- Issue #8419: Prevent the dict constructor from accepting non-string keyword
5188 arguments.
5189
Victor Stinner14284c22010-04-23 12:02:30 +00005190- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00005191 indirectly Python signal handlers anymore because mywrite() ignores exceptions
5192 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00005196
Georg Brandl62069d32010-07-31 08:56:11 +00005197- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects

Victor Stinnerdcb24032010-04-22 12:08:36 +00005199
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00005200- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00005201 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00005284- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00005285 where the right hand operand is a set of constants, by turning the set into a

5287 against the constant instead of building a new set each time it is executed (a
5288 similar optimization already existed which turned a list of constants into a
5289 pre-built tuple). Patch and additional tests by Dave Malcolm.

5593 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00005594 applications that use a lot of regular expressions and limits the impact of
5595 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00006009- Issue #2531: Comparison operations between floats and Decimal instances now
6010 return a result based on the numeric values of the operands; previously they
6011 returned an arbitrary result based on the relative ordering of id(float) and
6012 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
6013 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00006017- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00006018 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandl62069d32010-07-31 08:56:11 +00006026- Comparisons using one of <, <=, >, >= between a complex instance and a
6027 Fractions instance now raise TypeError instead of returning True/False. This
6028 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6029 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00006072- The internals of the subprocess module on POSIX systems have been replaced by
6073 an extension module (_posixsubprocess) so that the fork()+exec() can be done
6074 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00006076- subprocess.Popen now has restore_signals and start_new_session features. The
6077 default of restore_signals=True is a new behavior compared to earlier Python
6078 versions. This means that signals such as SIGPIPE are not ignored by default
6079 in subprocesses launched by Python (Issue #1652).

Antoine Pitroua32f9a22010-01-27 21:18:57 +00006170- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02006171 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00006172 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006173 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00006174 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00006572- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00006573 compared to other unix systems. In particular, os.getgroups() does not reflect

6576 groups on MacOSX.

Georg Brandl88b95f92012-05-06 11:24:06 +02006933 referenced. This also introduces a new private function:

Antoine Pitrou61f77b52009-05-24 15:46:13 +00007142- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
7143 than an int, which makes some operations possible under 64-bit Linux (e.g.
7144 DN_MULTISHOT with F_NOTIFY).
7145
Antoine Pitrou716c4442009-05-23 19:04:03 +00007146- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitrouc3ee1662009-05-23 16:02:33 +00007152- Issue #1983: Fix functions taking or returning a process identifier to use
7153 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
7154 a process identifier type wider than the standard C integer type.

7167
Antoine Pitroue4501852009-05-14 18:55:55 +00007168- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
7169 library. This means, for example, that opening an UTF-16 text file in
7170 append mode doesn't add a BOM at the end of the file if the file isn't
7171 empty.
7172
R. David Murray74b89242009-05-13 17:33:03 +00007173- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
7174 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
7175 corrects a pydoc regression.
7176
Georg Brandl5f90d792010-08-01 22:31:05 +00007177- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00007178 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00007220
7221Core and Builtins
7222-----------------
7223
Mark Dickinson865e01a2009-05-07 16:37:01 +00007224- Issue #5914: Add new C API function PyOS_string_to_double, and
7225 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
7226
Eric Smith741191f2009-05-06 13:08:15 +00007227- Issue #3382: float.__format__, complex.__format__, and %-formatting
7228 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
7229 affects nan -> NAN and inf -> INF.
7230
Mark Hammond5a607a32009-05-06 08:04:54 +00007231- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
7232 in all operations, including splitdrive, split, etc. splitunc() now issues
7233 a PendingDeprecation warning.
7234
Eric Smith63376222009-05-05 14:04:18 +00007235- Issue #5920: For float.__format__, change the behavior with the
7236 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
7237 to be like 'g' but with at least one decimal point and with a
7238 default precision of 12. Previously, the behavior the same but with
7239 a default precision of 6. This more closely matches str(), and
7240 reduces surprises when adding alignment flags to the empty
7241 presentation type. This also affects the new complex.__format__ in
7242 the same way.
7243
Martin v. Löwis011e8422009-05-05 04:43:17 +00007244- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
7245
R. David Murrayb18500d2009-05-04 22:59:07 +00007246- Issue #5890: in subclasses of 'property' the __doc__ attribute was
7247 shadowed by classtype's, even if it was None. property now
7248 inserts the __doc__ into the subclass instance __dict__.
7249
Antoine Pitrou244651a2009-05-04 18:56:13 +00007250- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
7251 sequences. Patch by Nick Barnes and Victor Stinner.
7252
Martin v. Löwise0a2b722009-05-10 08:08:56 +00007253- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00007254
Benjamin Petersond2e0c792009-05-01 20:40:59 +00007255- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
7256 received a new method, detach(). detach() disconnects the underlying stream
7257 from the buffer or text IO and returns it.
7258
Mark Dickinson33841c32009-05-01 15:37:04 +00007259- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
7260 floats with absolute value over 1e50. Also remove length
7261 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
7262 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00007263
Eric Smith741191f2009-05-06 13:08:15 +00007264- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00007265 format(complex(1, 2./3), '.5') now produces a sensible result.
7266
Mark Dickinsond3ca5572009-04-29 18:47:07 +00007267- Issue #5864: Fix empty format code formatting for floats so that it
7268 never gives more than the requested number of significant digits.
7269
Eric Smith6dc46f52009-04-27 20:39:49 +00007270- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
7271 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
7272
Eric Smithcc32a112009-04-26 21:35:14 +00007273- Issue #5835: Deprecate PyOS_ascii_formatd.
7274
Martin v. Löwis71efeb72009-04-26 01:02:07 +00007275- Issue #4971: Fix titlecase for characters that are their own
7276 titlecase, but not their own uppercase.
7277
Benjamin Peterson193152c2009-04-25 01:08:45 +00007278- Issue #5283: Setting __class__ in __del__ caused a segfault.
7279
Mark Dickinsonad476da2009-04-23 19:14:16 +00007280- Issue #5816: complex(repr(z)) now recovers z exactly, even when
7281 z involves nans, infs or negative zeros.
7282
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00007283- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00007284
Mark Dickinsone6a076d2009-04-18 11:48:33 +00007285- Issue #1869 (and many duplicates): make round(x, n) correctly
7286 rounded for a float x, by using the decimal <-> binary conversions
7287 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
7288 consistently agrees with format(x, '.2f').
7289
Benjamin Petersonae937c02009-04-18 20:54:08 +00007290- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
7291 some builtin types.
7292
Eric Smith0923d1d2009-04-16 20:16:10 +00007293- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
7294
Eric Smith35e84722009-04-16 20:21:28 +00007295- Issue #5515: str.format() type 'n' combined with commas and leading
7296 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00007297
7298- Implement PEP 378, Format Specifier for Thousands Separator, for
7299 floats.
7300
Mark Dickinson3370cce2009-04-17 22:40:53 +00007301- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007302 1e11, not 1e12. This avoids printing 13 significant digits in
7303 situations where only 12 of them are correct. Example problem
7304 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
7305 long time.)
7306
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007307- Issue #1580: On most platforms, use a 'short' float repr: for a
7308 finite float x, repr(x) now outputs a string based on the shortest
7309 sequence of decimal digits that rounds to x. Previous behaviour was
7310 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00007311 Another minor difference is that the new repr switches to
7312 exponential notation at 1e16 instead of the previous 1e17; this
7313 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007314
7315 There's a new sys attribute sys.float_repr_style, which takes
7316 the value 'short' to indicate that we're using short float repr,
7317 and 'legacy' if the short float repr isn't available for one
7318 reason or another.
7319
7320 The float repr change involves incorporating David Gay's 'perfect
7321 rounding' code into the Python core (it's in Python/dtoa.c). As a
7322 secondary consequence, all string-to-float and float-to-string
7323 conversions (including all float formatting operations) will be
7324 correctly rounded on these platforms.
7325
Georg Brandl5f90d792010-08-01 22:31:05 +00007326 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007327 this change does not apply.
7328
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00007329- Issue #5759: float() didn't call __float__ on str subclasses.
7330
Georg Brandlabc38772009-04-12 15:51:51 +00007331- The string.maketrans() function is deprecated; there is a new static method
7332 maketrans() on the bytes and bytearray classes. This removes confusion about
7333 the types string.maketrans() is supposed to work with, and mirrors the
7334 methods available on the str class.
7335
R. David Murraydc6da8a2009-04-09 22:16:43 +00007336- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
7337 its clarity and its speed.
7338
Georg Brandl65ce6ad2010-09-05 17:32:31 +00007339- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00007340 to avoid compiler warnings.
7341
Walter Dörwald8dc33d52009-05-06 14:41:26 +00007342- Issue #3739: The unicode-internal encoder now reports the number of characters
7343 consumed like any other encoder (instead of the number of bytes).

7501
Antoine Pitrou3a652b12009-03-23 18:52:06 +00007502- Issue #4688: Add a heuristic so that tuples and dicts containing only
7503 untrackable objects are not tracked by the garbage collector. This can
7504 reduce the size of collections and therefore the garbage collection overhead
7505 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00007575- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
7576 forever on incomplete input. That caused tarfile.open() to hang when used
7577 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
7578 partial bzip2 compressed data.
7579
Mark Dickinson79f52032009-03-17 23:12:51 +00007580- Issue #2110: Add support for thousands separator and 'n' type

7692 previously buffered data). Patch by Dmitry Vasiliev.
7693
Antoine Pitrou05608432009-01-09 18:53:14 +00007694- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
7695 flag to work properly. Furthermore, when specifying -u, the text stdout
7696 and stderr streams have line-by-line buffering enabled (the default being
7697 to buffer arbitrary chunks of data).
7698
Raymond Hettinger35631532009-01-09 03:58:09 +00007699- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
7700 instead of ints (reducing its size from 4 to 8 times thereby reducing
7701 Python's overall memory).
7702
Antoine Pitroud35cbf62009-01-06 19:02:24 +00007703- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
7704 an existing .py counterpart, override the co_filename attributes of all
7705 code objects if the original filename is obsolete (which can happen if the
7706 file has been renamed, moved, or if it is accessed through different paths).

7710 one byte. Also fixes the meaning of len() so that it returns the number of
7711 items, rather than the size in bytes.
7712
Martin v. Löwis5c88d812009-01-02 20:47:48 +00007713- Issue #4075: Use OutputDebugStringW in Py_FatalError.

8100
Antoine Pitrou08838b62009-01-21 00:55:13 +00008101- Issue #5008: When a file is opened in append mode with the new IO library,
8102 do an explicit seek to the end of file (so that e.g. tell() returns the
8103 file size rather than 0). This is consistent with the behaviour of the

8134 appropriately when it is being used via socket.makefile() objects
8135 rather than delaying the close by waiting for garbage collection to do it.
8136
Raymond Hettingerb8baf632009-01-14 02:20:07 +00008137- Issue #1696199: Add collections.Counter() for rapid and convenient
