900 context still remains available as the __context__ attribute.
901
Stefan Krah9a2d99e2012-02-25 12:24:21 +0100902- Issue #10181: New memoryview implementation fixes multiple ownership
903 and lifetime issues of dynamically allocated Py_buffer members (#9990)
904 as well as crashes (#8305, #7433). Many new features have been added
905 (See whatsnew/3.3), and the documentation has been updated extensively.
906 The ndarray test object from _testbuffer.c implements all aspects of
907 PEP-3118, so further development towards the complete implementation
908 of the PEP can proceed in a test-driven manner.
909
910 Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
911 and many ideas.

1478
Ned Deily99377482012-02-10 13:01:08 +01001479- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1480 Distutils-based packages with C extension modules may fail because
1481 Apple has removed gcc-4.2, the version used to build python.org
1482 64-bit/32-bit Pythons. If the user does not explicitly override
1483 the default C compiler by setting the CC environment variable,
1484 Distutils will now attempt to compile extension modules with clang
1485 if gcc-4.2 is required but not found. Also as a convenience, if
1486 the user does explicitly set CC, substitute its value as the default
1487 compiler in the Distutils LDSHARED configuration variable for OS X.
1488 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1489 SDK, neither of which are available in Xcode 4. This change does not
1490 attempt to override settings to support their use with Xcode 4.)

1497 backwards compatibility.
1498
Brett Cannonb4e63b32012-02-08 18:52:56 -05001499- When '' is a path (e.g. in sys.path), make sure __file__ uses the current
Brett Cannon32b66be2012-02-08 18:53:46 -05001500 working directory instead of '' in importlib.

2069 Condition, etc.) used to be factory functions returning instances of hidden
2070 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

2216
Ned Deily657b2de2011-06-28 19:51:30 -07002217- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2218 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2219 interpreter process. This could cause failures in non-Distutils subprocesses
2220 and was unreliable since tests or user programs could modify the interpreter
2221 environment after Distutils set it. Instead, have Distutils set the the
2222 deployment target only in the environment of each build subprocess. It is
2223 still possible to globally override the default by setting
2224 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2225 greater or equal to the default value, the value with which the interpreter

Nadeem Vawda3c01d162011-08-01 23:48:26 +02003043- Issue #11651: Improve the Makefile test targets to run more of the test suite
3044 more quickly. The --multiprocess option is now enabled by default, reducing
3045 the amount of time needed to run the tests. "make test" and "make quicktest"
3046 now include some resource-intensive tests, but no longer run the test suite
3047 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02003048 an easy platform-independent way to run test suite with sensible defaults.

3357 files in binary mode, using the email package's binary support to parse
3358 arbitrary email messages. StringIO and text file input is deprecated,

3418 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00003419
3420- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00003421 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00003422 that for incoming headers which makes this behaviour now consistent in
3423 both incoming and outgoing direction.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00004179- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
4180 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00004181 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00004182 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00004183 encoding and to encode command line arguments on this OS.

4186 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson230b2062010-10-16 03:45:45 +00004189- Issue #9997: Don't let the name "top" have special significance in scope
4190 resolution.

4578 with a non-empty format string. This is an effort to future-proof user
4579 code. If a derived class does not currently implement __format__ but later
4580 adds its own __format__, it would most likely break user code that had

Antoine Pitrou1df15362010-09-13 14:16:46 +00004584- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
4585 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
4586 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004640 replacement for old handle_accept() and avoids the user to call accept()

Raymond Hettingerfa11db02010-09-12 04:12:42 +00004747- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00004748 it possible for the user to create self-referencing ordered dictionaries which
4749 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00004750 approach of using weakref proxies so that reference cycles never get created
4751 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00004757- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING

4759 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00004776- Issue #6394: os.getppid() is now supported on Windows. Note that it will
4777 still return the id of the parent process after it has exited. This process
4778 id may even have been reused by another unrelated process.
4779
Georg Brandl27a28582010-10-10 09:49:21 +00004780- Issue #9792: In case of connection failure, socket.create_connection() would

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00004789- Updates to the random module:
4790
Georg Brandl27a28582010-10-10 09:49:21 +00004791 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00004794 * Update the seed() method to use all of the bits in a string instead of just
4795 the hash value. This makes better use of the seed value and assures the
4796 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00004797
Georg Brandl27a28582010-10-10 09:49:21 +00004798 * Improved the random()-->integer algorithm used in choice(), shuffle(),
4799 sample(), randrange(), and randint(). Formerly, it used int(n*random())
4800 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00004801
4802 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00004821- hashlib has two new constant attributes: algorithms_guaranteed and
4822 algorithms_avaiable that respectively list the names of hash algorithms
4823 guaranteed to exist in all Python implementations and the names of hash
4824 algorithms available in the current process.
4825
Brian Quinlanaf38dc52010-09-21 12:28:43 +00004826- A new package ``concurrent.futures`` as defined by PEP 3148.

4953 return characters from the full Unicode range, even on narrow unicode builds
4954 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
4955 in Python is that unicodedata.numeric() now returns the correct value for
4956 large code points, and repr() may consider more characters as printable.
4957
Victor Stinner6c00c142010-08-17 23:37:11 +00004958- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00004975 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
4976 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00004982- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
4983 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00004984

4991 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00004992
Georg Brandl649971e2010-09-05 17:06:50 +00004993- Issue #9416: Fix some issues with complex formatting where the output with no
4994 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00004995
4996 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
4997 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +00005329- Issue #8991: convertbuffer() rejects discontigious buffers.
5330
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00005331- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
5332 compiler.
5333
Benjamin Petersonccabcd42010-07-07 20:54:01 +00005334- Issue #8413: structsequence now subclasses tuple.
5335
Ezio Melotti57221d02010-07-01 07:32:02 +00005336- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00005337 start byte and the continuation byte(s) are now considered invalid, instead of
5338 the number of bytes specified by the start byte. E.g.:
5339 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
5340 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5341 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
5342 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00005343
Georg Brandl62069d32010-07-31 08:56:11 +00005344- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
5345 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00005346
Benjamin Peterson88968ad2010-06-25 19:30:21 +00005347- Be more specific in error messages about positional arguments.
5348
Victor Stinner4aae1eb2010-06-24 22:08:25 +00005349- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
5350 objects, as described in the documentation.

Georg Brandl62069d32010-07-31 08:56:11 +00005356- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
5357 dealing with unary minus applied to a constant. The removed code was mutating
5358 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00005359
Victor Stinner554f3f02010-06-16 23:33:54 +00005360- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00005361 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00005362 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00005363 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00005364
Victor Stinner25e8ec42010-06-25 00:02:38 +00005365- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
5366 "w*" format instead. Add tests for "w*" format.
5367
Victor Stinner06e49dd2010-06-13 18:21:50 +00005368- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00005369 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00005370 string formats.
5371
Georg Brandl62069d32010-07-31 08:56:11 +00005372- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00005373 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
5374 location of the raised exception.
5375
Victor Stinner313a1202010-06-11 23:56:51 +00005376- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
5377 filenames and enable os.fsencode().
5378
Benjamin Peterson285a6892010-06-22 19:21:52 +00005379- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
5380
Georg Brandl62069d32010-07-31 08:56:11 +00005381- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
5382 interpreter with characters outside the Basic Multilingual Plane (higher than
5383 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00005384
Georg Brandl62069d32010-07-31 08:56:11 +00005385- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
5386 TypeError instead of giving a DeprecationWarning when a float is parsed using
5387 the 'L' code (for long long). (All other integer codes already raise
5388 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00005389
Victor Stinner600d3be2010-06-10 12:00:55 +00005390- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
5391 enable shortcuts for upper case encoding name. Add also a shortcut for
5392 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
5393
Georg Brandl62069d32010-07-31 08:56:11 +00005394- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
5395 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005396
5397- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00005398 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005399 like bytearray.
5400
Georg Brandl62069d32010-07-31 08:56:11 +00005401- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00005402 used anymore and it was never documented.
5403
Georg Brandl62069d32010-07-31 08:56:11 +00005404- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00005405
Georg Brandl62069d32010-07-31 08:56:11 +00005406- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
5407 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00005408
Georg Brandl62069d32010-07-31 08:56:11 +00005409- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
5410 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
5411 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
5412 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00005413
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005414- Issue #8748: Fix two issues with comparisons between complex and integer
5415 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00005416 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
5417 (2) The comparison raised an OverflowError for large integers, leading to
5418 unpredictable exceptions when combining integers and complex objects in sets
5419 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005420
Victor Stinner7d79b8b2010-05-19 20:40:50 +00005421- Issue #8766: Initialize _warnings module before importing the first module.
5422 Fix a crash if an empty directory called "encodings" exists in sys.path.
5423
Victor Stinner9ca9c252010-05-19 16:53:30 +00005424- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00005425 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00005426 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00005427
Georg Brandl62069d32010-07-31 08:56:11 +00005428- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
5429 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00005430
Victor Stinnerae6265f2010-05-15 16:27:27 +00005431- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
5432 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00005433 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00005434 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00005435
Victor Stinner59e62db2010-05-15 13:14:32 +00005436- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00005437 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00005438
Victor Stinnerb744ba12010-05-15 12:27:16 +00005439- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00005440 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00005441 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
5442
Victor Stinner0964ee12010-04-30 16:48:45 +00005443- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00005444 PyUnicode_FromString() to support surrogates in the filename and use the right
5445 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00005446
Georg Brandl8569e582010-05-19 20:57:08 +00005447- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
5448
Georg Brandl62069d32010-07-31 08:56:11 +00005449- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00005450
Benjamin Petersonfb886362010-04-24 18:21:17 +00005451- Issue #8419: Prevent the dict constructor from accepting non-string keyword
5452 arguments.
5453
Victor Stinner14284c22010-04-23 12:02:30 +00005454- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00005455 indirectly Python signal handlers anymore because mywrite() ignores exceptions
5456 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00005457
Victor Stinner31be90b2010-04-22 19:38:16 +00005458- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00005459 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00005460
Georg Brandl62069d32010-07-31 08:56:11 +00005461- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
5462 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00005463
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00005464- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00005465 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
5466 compared to the dynamic memory allocation fallback. Patch by Charles-François
5467 Natali.

5545 crash in many places because of the PyByteArray_AS_STRING() macro returning
5546 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00005548- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00005549 where the right hand operand is a set of constants, by turning the set into a
5550 frozenset and pre-building it as a constant. The comparison operation is made
5551 against the constant instead of building a new set each time it is executed (a
5552 similar optimization already existed which turned a list of constants into a
5553 pre-built tuple). Patch and additional tests by Dave Malcolm.

5580 least on IEEE 754 platforms), and in particular does not depend on the
5581 internal representation of an int.

5857 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00005858 applications that use a lot of regular expressions and limits the impact of
5859 the performance hit anytime the cache is exceeded.

Georg Brandl88b95f92012-05-06 11:24:06 +02006231- Issue #7316: The acquire() method of lock objects in the ``threading``
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00006232 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00006233 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00006259- Issue #8257: The Decimal construct now accepts a float instance directly,
6260 converting that float to a Decimal of equal value:

Georg Brandl62069d32010-07-31 08:56:11 +00006268- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6269 InvalidOperation instead of returning False. (Comparisons involving a quiet
6270 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6271 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00006273- Issue #2531: Comparison operations between floats and Decimal instances now
6274 return a result based on the numeric values of the operands; previously they
6275 returned an arbitrary result based on the relative ordering of id(float) and
6276 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
6277 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006278
Raymond Hettinger9c01e442010-04-03 10:32:58 +00006279- Added a subtract() method to collections.Counter().
6280
Barry Warsawd5f9bf52010-03-31 21:36:22 +00006281- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00006282 argument `-` which tells it to read files to compile from stdin. Each line is
6283 read on demand and the named file is compiled immediately. (Original patch by
6284 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00006286- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00006290- Comparisons using one of <, <=, >, >= between a complex instance and a
6291 Fractions instance now raise TypeError instead of returning True/False. This
6292 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6293 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00006336- The internals of the subprocess module on POSIX systems have been replaced by
6337 an extension module (_posixsubprocess) so that the fork()+exec() can be done
6338 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00006339
Georg Brandl62069d32010-07-31 08:56:11 +00006340- subprocess.Popen now has restore_signals and start_new_session features. The
6341 default of restore_signals=True is a new behavior compared to earlier Python
6342 versions. This means that signals such as SIGPIPE are not ignored by default
6343 in subprocesses launched by Python (Issue #1652).

6430 position when calling `truncate()`. It would previously change the file
6431 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00006432 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
6433
Antoine Pitroua32f9a22010-01-27 21:18:57 +00006434- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02006435 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00006436 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006437 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00006438 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00006836- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00006837 compared to other unix systems. In particular, os.getgroups() does not reflect
6838 any changes made using os.setgroups() but basicly always returns the same
6839 information as the id command. os.getgroups() can now return more than 16
6840 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00007432- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
7433 library. This means, for example, that opening an UTF-16 text file in
7434 append mode doesn't add a BOM at the end of the file if the file isn't
7435 empty.
7436
R. David Murray74b89242009-05-13 17:33:03 +00007437- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
7438 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
7439 corrects a pydoc regression.
7440
Georg Brandl5f90d792010-08-01 22:31:05 +00007441- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00007442 now it does. This also means getfp method now returns the real fp.

7485Core and Builtins
7486-----------------
7487
Mark Dickinson865e01a2009-05-07 16:37:01 +00007488- Issue #5914: Add new C API function PyOS_string_to_double, and
7489 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
7490
Eric Smith741191f2009-05-06 13:08:15 +00007491- Issue #3382: float.__format__, complex.__format__, and %-formatting
7492 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
7493 affects nan -> NAN and inf -> INF.
7494
Mark Hammond5a607a32009-05-06 08:04:54 +00007495- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
7496 in all operations, including splitdrive, split, etc. splitunc() now issues
7497 a PendingDeprecation warning.
7498
Eric Smith63376222009-05-05 14:04:18 +00007499- Issue #5920: For float.__format__, change the behavior with the
7500 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
7501 to be like 'g' but with at least one decimal point and with a
7502 default precision of 12. Previously, the behavior the same but with
7503 a default precision of 6. This more closely matches str(), and
7504 reduces surprises when adding alignment flags to the empty
7505 presentation type. This also affects the new complex.__format__ in
7506 the same way.
7507
Martin v. Löwis011e8422009-05-05 04:43:17 +00007508- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
7509
R. David Murrayb18500d2009-05-04 22:59:07 +00007510- Issue #5890: in subclasses of 'property' the __doc__ attribute was
7511 shadowed by classtype's, even if it was None. property now
7512 inserts the __doc__ into the subclass instance __dict__.
7513
Antoine Pitrou244651a2009-05-04 18:56:13 +00007514- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
7515 sequences. Patch by Nick Barnes and Victor Stinner.
7516
Martin v. Löwise0a2b722009-05-10 08:08:56 +00007517- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00007518
Benjamin Petersond2e0c792009-05-01 20:40:59 +00007519- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
7520 received a new method, detach(). detach() disconnects the underlying stream
7521 from the buffer or text IO and returns it.
7522
Mark Dickinson33841c32009-05-01 15:37:04 +00007523- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
7524 floats with absolute value over 1e50. Also remove length
7525 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
7526 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00007527
Eric Smith741191f2009-05-06 13:08:15 +00007528- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00007529 format(complex(1, 2./3), '.5') now produces a sensible result.
7530
Mark Dickinsond3ca5572009-04-29 18:47:07 +00007531- Issue #5864: Fix empty format code formatting for floats so that it
7532 never gives more than the requested number of significant digits.
7533
Eric Smith6dc46f52009-04-27 20:39:49 +00007534- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
7535 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
7536
Eric Smithcc32a112009-04-26 21:35:14 +00007537- Issue #5835: Deprecate PyOS_ascii_formatd.
7538
Martin v. Löwis71efeb72009-04-26 01:02:07 +00007539- Issue #4971: Fix titlecase for characters that are their own
7540 titlecase, but not their own uppercase.
7541
Benjamin Peterson193152c2009-04-25 01:08:45 +00007542- Issue #5283: Setting __class__ in __del__ caused a segfault.
7543
Mark Dickinsonad476da2009-04-23 19:14:16 +00007544- Issue #5816: complex(repr(z)) now recovers z exactly, even when
7545 z involves nans, infs or negative zeros.
7546
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00007547- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00007548
Mark Dickinsone6a076d2009-04-18 11:48:33 +00007549- Issue #1869 (and many duplicates): make round(x, n) correctly
7550 rounded for a float x, by using the decimal <-> binary conversions
7551 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
7552 consistently agrees with format(x, '.2f').
7553
Benjamin Petersonae937c02009-04-18 20:54:08 +00007554- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
7555 some builtin types.
7556
Eric Smith0923d1d2009-04-16 20:16:10 +00007557- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
7558
Eric Smith35e84722009-04-16 20:21:28 +00007559- Issue #5515: str.format() type 'n' combined with commas and leading
7560 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00007561
7562- Implement PEP 378, Format Specifier for Thousands Separator, for
7563 floats.
7564
Mark Dickinson3370cce2009-04-17 22:40:53 +00007565- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007566 1e11, not 1e12. This avoids printing 13 significant digits in
7567 situations where only 12 of them are correct. Example problem
7568 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
7569 long time.)
7570
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007571- Issue #1580: On most platforms, use a 'short' float repr: for a
7572 finite float x, repr(x) now outputs a string based on the shortest
7573 sequence of decimal digits that rounds to x. Previous behaviour was
7574 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00007575 Another minor difference is that the new repr switches to
7576 exponential notation at 1e16 instead of the previous 1e17; this
7577 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007578
7579 There's a new sys attribute sys.float_repr_style, which takes
7580 the value 'short' to indicate that we're using short float repr,
7581 and 'legacy' if the short float repr isn't available for one
7582 reason or another.
7583
7584 The float repr change involves incorporating David Gay's 'perfect
7585 rounding' code into the Python core (it's in Python/dtoa.c). As a
7586 secondary consequence, all string-to-float and float-to-string
7587 conversions (including all float formatting operations) will be
7588 correctly rounded on these platforms.
7589
Georg Brandl5f90d792010-08-01 22:31:05 +00007590 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007591 this change does not apply.
7592
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00007593- Issue #5759: float() didn't call __float__ on str subclasses.
7594
Georg Brandlabc38772009-04-12 15:51:51 +00007595- The string.maketrans() function is deprecated; there is a new static method
7596 maketrans() on the bytes and bytearray classes. This removes confusion about
7597 the types string.maketrans() is supposed to work with, and mirrors the
7598 methods available on the str class.
7599
R. David Murraydc6da8a2009-04-09 22:16:43 +00007600- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
7601 its clarity and its speed.
7602
Georg Brandl65ce6ad2010-09-05 17:32:31 +00007603- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00007604 to avoid compiler warnings.
7605
Walter Dörwald8dc33d52009-05-06 14:41:26 +00007606- Issue #3739: The unicode-internal encoder now reports the number of characters
7607 consumed like any other encoder (instead of the number of bytes).

7745
Benjamin Peterson7fe98532009-04-02 00:33:55 +00007746- Issue #5499: The 'c' code for argument parsing functions now only accepts a
7747 byte, and the 'C' code only accepts a unicode character.
7748
Georg Brandl406b3d82009-04-11 21:24:37 +00007749- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
7750 when hitting the recursion limit under certain circumstances.
7751
Brett Cannon0759dd62009-04-01 18:13:07 +00007752- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
7753
Georg Brandlab6f2f62009-03-31 04:16:10 +00007754- Fix a segfault when running test_exceptions with coverage, caused by
7755 insufficient checks in accessors of Exception.__context__.
7756
Guido van Rossum0ad59d42009-03-30 22:01:35 +00007757- Issue #5604: non-ASCII characters in module name passed to
7758 imp.find_module() were converted to UTF-8 while the path is
7759 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00007761- Issue #5126: str.isprintable() returned False for space characters.
7762
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00007763- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
7764 the end sys.path, for compatibility with the system install of Python.
7765
Antoine Pitrou3a652b12009-03-23 18:52:06 +00007766- Issue #4688: Add a heuristic so that tuples and dicts containing only
7767 untrackable objects are not tracked by the garbage collector. This can
7768 reduce the size of collections and therefore the garbage collection overhead
7769 on long-running programs, depending on their particular use of datatypes.
7770
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00007771- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

7783 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
7784 and sizeof(Py_UNICODE) == 2.
7785
Eric Smith8ec90442009-03-14 12:29:34 +00007786- Issue #5237: Allow auto-numbered fields in str.format(). For

7788
Antoine Pitrou652e7072009-03-13 19:25:20 +00007789- Issue #5392: when a very low recursion limit was set, the interpreter would
7790 abort with a fatal error after the recursion limit was hit twice.
7791
Matthias Klose042f1332009-04-04 14:32:42 +00007792- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

7802 error substitutions from non-strict codec error callbacks in
7803 incrementalencoder and StreamWriter.
7804
Georg Brandl33c28812009-04-01 23:07:29 +00007805- Issue #5656: Fix the coverage reporting when running the test suite with

7835
Benjamin Peterson59406a92009-03-26 17:10:29 +00007836- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
7837 io.BufferedRandom have been deprecated for removal in Python 3.2.
7838
Lars Gustäbel42e00912009-03-22 20:34:29 +00007839- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
7840 forever on incomplete input. That caused tarfile.open() to hang when used
7841 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
7842 partial bzip2 compressed data.
7843
Mark Dickinson79f52032009-03-17 23:12:51 +00007844- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +00007861- Issue #5463: In struct module, remove deprecated overflow wrapping
7862 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00007863 struct.error instead of returning b'\xff\xff\xff\xff'. The
7864 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
7865 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00007892- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
7893 it now forces its argument to double before testing for infinity.
7894
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00007895- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
7896 returns a non-number type.
7897
Benjamin Peterson87618552009-02-08 15:00:52 +00007898- Issue #5182: Removed memoryview.__str__.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00007905- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00007906 were suppressing all exceptions. These include list() and bytearray().
7907
Mark Dickinson1124e712009-01-28 21:25:58 +00007908- Issue #4707: round(x, n) now returns an integer if x is an integer.
7909 Previously it returned a float.
7910
Antoine Pitroub52ec782009-01-25 16:34:23 +00007911- Issue #4753: By enabling a configure option named '--with-computed-gotos'
7912 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
7913 evaluation loop is compiled with a new dispatch mechanism which gives
7914 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00007929- Issue #4935: The overflow checking code in the expandtabs() method common
7930 to str, bytes and bytearray could be optimized away by the compiler, letting
7931 the interpreter segfault instead of raising an error.
7932
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00007933- Issue #3720: Fix a crash when an iterator modifies its class and removes its

7945 common cases are optimized thanks to a dedicated fast path and a moderate
7946 amount of loop unrolling.
7947
Antoine Pitrou14b78f52009-01-09 22:27:08 +00007948- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
7949 collecting the oldest generation) so that allocating lots of objects without
7950 destroying them does not show quadratic performance. Based on a proposal by

Antoine Pitrou8043cf82009-01-09 19:54:29 +00007955 having been closed (for instance, a read() call could return some
7956 previously buffered data). Patch by Dmitry Vasiliev.
7957
Antoine Pitrou05608432009-01-09 18:53:14 +00007958- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
7959 flag to work properly. Furthermore, when specifying -u, the text stdout
7960 and stderr streams have line-by-line buffering enabled (the default being
7961 to buffer arbitrary chunks of data).
7962
Raymond Hettinger35631532009-01-09 03:58:09 +00007963- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
7964 instead of ints (reducing its size from 4 to 8 times thereby reducing
7965 Python's overall memory).
7966
Antoine Pitroud35cbf62009-01-06 19:02:24 +00007967- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
7968 an existing .py counterpart, override the co_filename attributes of all
7969 code objects if the original filename is obsolete (which can happen if the
7970 file has been renamed, moved, or if it is accessed through different paths).
7971 Patch by Ziga Seilnacht and Jean-Paul Calderone.
7972
Antoine Pitrouc3b39242009-01-03 16:59:18 +00007973- Issue #4580: Fix slicing of memoryviews when the item size is greater than
7974 one byte. Also fixes the meaning of len() so that it returns the number of
7975 items, rather than the size in bytes.
7976
Martin v. Löwis5c88d812009-01-02 20:47:48 +00007977- Issue #4075: Use OutputDebugStringW in Py_FatalError.
7978
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00007979- Issue #4747: When the terminal does not use utf-8, executing a script with

7987
Nick Coghlanf1f2f682008-12-30 07:29:12 +00007988- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
7989 where the tp_hash and tp_dict slots are both NULL.
7990
Georg Brandlccc47b62008-12-28 11:44:14 +00007991- Issue #4759: None is now allowed as the first argument of
7992 bytearray.translate(). It was always allowed for bytes.translate().
7993
Skip Montanaro80072cb2008-12-23 03:51:14 +00007994- Added test case to ensure attempts to read from a file opened for writing

8364
Antoine Pitrou08838b62009-01-21 00:55:13 +00008365- Issue #5008: When a file is opened in append mode with the new IO library,
8366 do an explicit seek to the end of file (so that e.g. tell() returns the

8398 appropriately when it is being used via socket.makefile() objects
8399 rather than delaying the close by waiting for garbage collection to do it.
8400
Raymond Hettingerb8baf632009-01-14 02:20:07 +00008401- Issue #1696199: Add collections.Counter() for rapid and convenient
