10Core and Builtins
11-----------------
12
Benjamin Petersonbbb04122010-10-30 23:16:28 +000013- If FileIO.__init__ fails, close the file descriptor.
14
Raymond Hettingerdd421542010-10-30 08:10:29 +000015- Issue #10221: dict.pop(k) now has a key error message that includes the
16 missing key (same message d[k] returns for missing keys).
17
Antoine Pitrou07e20ef2010-10-28 22:56:58 +000018- Issue #5437: A preallocated MemoryError instance should not hold traceback
19 data (including local variables caught in the stack trace) alive infinitely.
20

22 of the offending line.
23
Victor Stinner75d8c5c2010-10-23 17:02:31 +000024- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
25 handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
26 code directory name contains a non-ASCII character and the locale encoding is
27 ASCII.
28
Antoine Pitrou9583cac2010-10-21 13:42:28 +000029- Issue #10089: Add support for arbitrary -X options on the command-line.

33 of the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
34 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
35 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
36 encoding and to encode command line arguments on this OS.
37
Victor Stinner4c7c8c32010-10-16 13:14:10 +000038- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
39 filenames encoded to the filesystem encoding with surrogateescape error
40 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
41
Benjamin Peterson230b2062010-10-16 03:45:45 +000042- Issue #9997: Don't let the name "top" have special significance in scope
43 resolution.
44
R. David Murraye16cda92010-10-15 23:12:57 +000045- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding
46 its value as the default 512 when compiling on AIX.
47
Victor Stinnerf3170cc2010-10-15 12:04:23 +000048- Use locale encoding instead of UTF-8 to encode and decode filenames if
49 Py_FileSystemDefaultEncoding is not set.
50
Victor Stinner22a351a2010-10-14 12:04:34 +000051- Issue #10095: fp_setreadl() doesn't reopen the file, reuse instead the file
52 descriptor.
53

295
Brett Cannon5305a992010-09-27 21:08:38 +0000296- Issue #7397: Mention that importlib.import_module() is probably what someone
297 really wants to be using in __import__'s docstring.
298
Georg Brandl27a28582010-10-10 09:49:21 +0000299- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
300 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000302- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +0000303 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +0000305- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000307- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
308 threads are still running. Instead, reinitialize the GIL on a second call to
309 Py_Initialize().
310
Georg Brandl27a28582010-10-10 09:49:21 +0000311- All SyntaxErrors now have a column offset and therefore a caret when the error
312 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +0000313
Brett Cannonbc2eff32010-09-19 21:39:02 +0000314- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
315 module that was imported, but instead gets the module from sys.modules.
316
Georg Brandl27a28582010-10-10 09:49:21 +0000317- Issue #9212: The range type_items now provides index() and count() methods, to
318 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +0000319
Georg Brandl27a28582010-10-10 09:49:21 +0000320- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
321 with a non-empty format string. This is an effort to future-proof user
322 code. If a derived class does not currently implement __format__ but later
323 adds its own __format__, it would most likely break user code that had
324 supplied a format string. This will be changed to a DeprecationWaring in
325 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +0000326
Antoine Pitrou1df15362010-09-13 14:16:46 +0000327- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
328 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
329 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
330
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000331- Issue #9210: Configure option --with-wctype-functions was removed. Using the
332 functions from the libc caused the methods .upper() and lower() to become
333 locale aware and created subtly wrong results.
334
Georg Brandl27a28582010-10-10 09:49:21 +0000335- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
336 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000337
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000338- Issue #4617: Previously it was illegal to delete a name from the local
339 namespace if it occurs as a free variable in a nested block. This limitation
340 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
341
Georg Brandl27a28582010-10-10 09:49:21 +0000342- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
343 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
344 Also, the "backslashreplace" error handler now joins surrogate pairs into a
345 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000347- Issue #9757: memoryview objects get a release() method to release the
348 underlying buffer (previously this was only done when deallocating the
349 memoryview), and gain support for the context management protocol.
350
Antoine Pitrou079ce542010-09-08 12:37:10 +0000351- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
352 thread-local storage key.

369 gettext.
370
Éric Araujoef777bd2010-10-05 00:04:20 +0000371- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000372 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000373 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000374 replacement for old handle_accept() and avoids the user to call accept()
375 directly.
376
Lars Gustäbel331b8002010-10-04 15:18:47 +0000377- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Georg Brandl27a28582010-10-10 09:49:21 +0000392- Issue #9360: Cleanup and improvements to the nntplib module. The API now
393 conforms to the philosophy of bytes and unicode separation in Python 3. A
394 test suite has also been added.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000398- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +0000399 retry the select() loop instead of bailing out. This is because select() can
400 incorrectly report a socket as ready for reading (for example, if it received
401 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000402
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +0000403- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
404
Antoine Pitrou6d7df632010-09-27 17:52:25 +0000405- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +0000406 received. Now sendall() properly calls signal handlers if necessary, and

437
Georg Brandl27a28582010-10-10 09:49:21 +0000438- logging: Changed LoggerAdapter implementation internally, to make it easier to
439 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +0000440
Vinay Sajipc84f0162010-09-21 11:25:39 +0000441- logging: hasHandlers method was added to Logger, and isEnabledFor,
442 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
443 LoggerAdapter was introduced into the unit tests for logging.

446
Antoine Pitrou98b46702010-09-18 22:59:00 +0000447- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +0000448 non-blocking mode: they return None when an operation would block (instead of
449 raising an exception).

Georg Brandl27a28582010-10-10 09:49:21 +0000461- Issue #1552: socket.socketpair() now returns regular socket.socket objects
462 supporting the whole socket API (rather than the "raw" _socket.socket
463 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +0000464
Georg Brandl27a28582010-10-10 09:49:21 +0000465- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

477
Georg Brandl27a28582010-10-10 09:49:21 +0000478- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +0000480
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000481- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000482 it possible for the user to create self-referencing ordered dictionaries which
483 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000484 approach of using weakref proxies so that reference cycles never get created
485 in the first place.
486
Victor Stinnercb043522010-09-10 23:49:04 +0000487- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
488 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +0000489 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +0000490
Georg Brandl27a28582010-10-10 09:49:21 +0000491- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
492 environment variable to set the filesystem encoding at Python startup.
493 sys.setfilesystemencoding() creates inconsistencies because it is unable to
494 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +0000495
Georg Brandl27a28582010-10-10 09:49:21 +0000496- Issue #9410: Various optimizations to the pickle module, leading to speedups
497 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
498 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000499
Georg Brandl27a28582010-10-10 09:49:21 +0000500- The pprint module now supports printing OrderedDicts in their given order
501 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +0000502
Vinay Sajip121a1c42010-09-08 10:46:15 +0000503- Logging: Added QueueHandler class to facilitate logging usage with
504 multiprocessing.
505
Georg Brandl27a28582010-10-10 09:49:21 +0000506- Issue #9707: Rewritten reference implementation of threading.local which is
507 friendlier towards reference cycles. This change is not normally visible
508 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +0000509
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000510- Issue #6394: os.getppid() is now supported on Windows. Note that it will
511 still return the id of the parent process after it has exited. This process
512 id may even have been reused by another unrelated process.
513
Georg Brandl27a28582010-10-10 09:49:21 +0000514- Issue #9792: In case of connection failure, socket.create_connection() would
515 swallow the exception and raise a new one, making it impossible to fetch the
516 original errno, or to filter timeout errors. Now the original error is
517 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +0000519- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
520 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
521 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +0000522
Raymond Hettinger435cb0f2010-09-06 23:36:31 +0000523- Updates to the random module:
524
Georg Brandl27a28582010-10-10 09:49:21 +0000525 * Document which parts of the module are guaranteed to stay the same across
526 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +0000527
Georg Brandl27a28582010-10-10 09:49:21 +0000528 * Update the seed() method to use all of the bits in a string instead of just
529 the hash value. This makes better use of the seed value and assures the
530 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000531
Georg Brandl27a28582010-10-10 09:49:21 +0000532 * Improved the random()-->integer algorithm used in choice(), shuffle(),
533 sample(), randrange(), and randint(). Formerly, it used int(n*random())
534 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000535
536 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +0000538- collections.OrderedDict now supports a new method for repositioning keys to
539 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +0000540
Georg Brandl27a28582010-10-10 09:49:21 +0000541- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
542 cases now also have assertWarns and assertWarnsRegexp methods to check that a

Victor Stinner8182b712010-07-28 00:40:58 +00001057- Issue #8991: convertbuffer() rejects discontigious buffers.
1058
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00001059- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
1060 compiler.

1063
Ezio Melotti57221d02010-07-01 07:32:02 +00001064- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001065 start byte and the continuation byte(s) are now considered invalid, instead of
1066 the number of bytes specified by the start byte. E.g.:
1067 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1068 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1069 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1070 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00001072- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
1073 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00001084- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
1085 dealing with unary minus applied to a constant. The removed code was mutating
1086 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00001087
Victor Stinner554f3f02010-06-16 23:33:54 +00001088- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00001089 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00001090 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001091 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00001092
Victor Stinner25e8ec42010-06-25 00:02:38 +00001093- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
1094 "w*" format instead. Add tests for "w*" format.
1095
Victor Stinner06e49dd2010-06-13 18:21:50 +00001096- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00001097 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00001098 string formats.
1099
Georg Brandl62069d32010-07-31 08:56:11 +00001100- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001101 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1102 location of the raised exception.
1103
Victor Stinner313a1202010-06-11 23:56:51 +00001104- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1105 filenames and enable os.fsencode().
1106
Benjamin Peterson285a6892010-06-22 19:21:52 +00001107- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
1108
Georg Brandl62069d32010-07-31 08:56:11 +00001109- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
1110 interpreter with characters outside the Basic Multilingual Plane (higher than
1111 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00001112
Georg Brandl62069d32010-07-31 08:56:11 +00001113- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1114 TypeError instead of giving a DeprecationWarning when a float is parsed using
1115 the 'L' code (for long long). (All other integer codes already raise
1116 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001117
Victor Stinner600d3be2010-06-10 12:00:55 +00001118- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1119 enable shortcuts for upper case encoding name. Add also a shortcut for
1120 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1121
Georg Brandl62069d32010-07-31 08:56:11 +00001122- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1123 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001124
1125- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001126 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001127 like bytearray.
1128
Georg Brandl62069d32010-07-31 08:56:11 +00001129- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001130 used anymore and it was never documented.
1131
Georg Brandl62069d32010-07-31 08:56:11 +00001132- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00001133
Georg Brandl62069d32010-07-31 08:56:11 +00001134- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
1135 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001136
Georg Brandl62069d32010-07-31 08:56:11 +00001137- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1138 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1139 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1140 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001141
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001142- Issue #8748: Fix two issues with comparisons between complex and integer
1143 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001144 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1145 (2) The comparison raised an OverflowError for large integers, leading to
1146 unpredictable exceptions when combining integers and complex objects in sets
1147 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001148
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001149- Issue #8766: Initialize _warnings module before importing the first module.
1150 Fix a crash if an empty directory called "encodings" exists in sys.path.
1151
Victor Stinner9ca9c252010-05-19 16:53:30 +00001152- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001153 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001154 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001155
Georg Brandl62069d32010-07-31 08:56:11 +00001156- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1157 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001158
Victor Stinnerae6265f2010-05-15 16:27:27 +00001159- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1160 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001161 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001162 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001163
Victor Stinner59e62db2010-05-15 13:14:32 +00001164- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001165 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001166
Victor Stinnerb744ba12010-05-15 12:27:16 +00001167- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001168 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001169 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1170
Victor Stinner0964ee12010-04-30 16:48:45 +00001171- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001172 PyUnicode_FromString() to support surrogates in the filename and use the right
1173 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00001174
Georg Brandl8569e582010-05-19 20:57:08 +00001175- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
1176
Georg Brandl62069d32010-07-31 08:56:11 +00001177- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00001178
Benjamin Petersonfb886362010-04-24 18:21:17 +00001179- Issue #8419: Prevent the dict constructor from accepting non-string keyword
1180 arguments.
1181
Victor Stinner14284c22010-04-23 12:02:30 +00001182- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00001183 indirectly Python signal handlers anymore because mywrite() ignores exceptions
1184 (KeyboardInterrupt).

Georg Brandl62069d32010-07-31 08:56:11 +00001189- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
1190 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00001191
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00001192- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00001193 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00001276- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00001277 where the right hand operand is a set of constants, by turning the set into a
1278 frozenset and pre-building it as a constant. The comparison operation is made
1279 against the constant instead of building a new set each time it is executed (a
1280 similar optimization already existed which turned a list of constants into a
1281 pre-built tuple). Patch and additional tests by Dave Malcolm.

1308 least on IEEE 754 platforms), and in particular does not depend on the
1309 internal representation of an int.

Antoine Pitrou3060c452010-08-13 16:27:38 +00001584 simply clearing the entire cache on overflow to forgetting the least recently
1585 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001586 applications that use a lot of regular expressions and limits the impact of
1587 the performance hit anytime the cache is exceeded.

1600 module is renamed to `_datetime` and if available, overrides all classes
1601 defined in datetime with fast C impementation. Python implementation is based
1602 on the original python prototype for the datetime module by Tim Peters with
1603 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00001959- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00001960 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00001961 relies on the system threading library, so as to avoid a semi-busy wait loop.

Victor Stinner485fb562010-04-13 11:07:24 +00001963- Issue #8383: pickle and pickletools use surrogatepass error handler when
1964 encoding unicode as utf8 to support lone surrogates and stay compatible with

R. David Murrayb2416e52010-04-12 16:58:02 +00001967- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00001968 filename and date, conforming to the 'standards' they were originally designed
1969 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00001985- Add functools.total_ordering() and functools.cmp_to_key().
1986
Georg Brandl62069d32010-07-31 08:56:11 +00001987- Issue #8257: The Decimal construct now accepts a float instance directly,
1988 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00001989
1990 >>> Decimal(1.1)
1991 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00001996- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1997 InvalidOperation instead of returning False. (Comparisons involving a quiet
1998 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1999 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00002001- Issue #2531: Comparison operations between floats and Decimal instances now
2002 return a result based on the numeric values of the operands; previously they
2003 returned an arbitrary result based on the relative ordering of id(float) and
2004 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2005 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002006
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002007- Added a subtract() method to collections.Counter().
2008
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002009- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002010 argument `-` which tells it to read files to compile from stdin. Each line is
2011 read on demand and the named file is compiled immediately. (Original patch by
2012 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00002014- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00002018- Comparisons using one of <, <=, >, >= between a complex instance and a
2019 Fractions instance now raise TypeError instead of returning True/False. This
2020 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2021 <=> complex, and complex <=> complex comparisons.

2029
Antoine Pitrou910bd512010-03-22 20:11:09 +00002030- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002031 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00002064- The internals of the subprocess module on POSIX systems have been replaced by
2065 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2066 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00002067
Georg Brandl62069d32010-07-31 08:56:11 +00002068- subprocess.Popen now has restore_signals and start_new_session features. The
2069 default of restore_signals=True is a new behavior compared to earlier Python
2070 versions. This means that signals such as SIGPIPE are not ignored by default
2071 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00002157- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
2158 position when calling `truncate()`. It would previously change the file
2159 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00002160 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2161
Antoine Pitroua32f9a22010-01-27 21:18:57 +00002162- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00002163 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
2164 archive. The new implementation is significantly faster and can be wrapped in
2165 a :class:`io.BufferedReader` object for more speedups. It also solves an
2166 issue where interleaved calls to `read()` and `readline()` give wrong results.
2167 Patch by Nir Aides.

Georg Brandl62069d32010-07-31 08:56:11 +00002503 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002564- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002565 compared to other unix systems. In particular, os.getgroups() does not reflect
2566 any changes made using os.setgroups() but basicly always returns the same
2567 information as the id command. os.getgroups() can now return more than 16
2568 groups on MacOSX.

2924 threads could return successfully while some Thread objects were still

3162 append mode doesn't add a BOM at the end of the file if the file isn't
3163 empty.
3164
R. David Murray74b89242009-05-13 17:33:03 +00003165- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
3166 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
3167 corrects a pydoc regression.
3168
Georg Brandl5f90d792010-08-01 22:31:05 +00003169- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00003170 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00003212
3213Core and Builtins
3214-----------------
3215
Mark Dickinson865e01a2009-05-07 16:37:01 +00003216- Issue #5914: Add new C API function PyOS_string_to_double, and
3217 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3218
Eric Smith741191f2009-05-06 13:08:15 +00003219- Issue #3382: float.__format__, complex.__format__, and %-formatting
3220 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
3221 affects nan -> NAN and inf -> INF.
3222
Mark Hammond5a607a32009-05-06 08:04:54 +00003223- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
3224 in all operations, including splitdrive, split, etc. splitunc() now issues
3225 a PendingDeprecation warning.
3226
Eric Smith63376222009-05-05 14:04:18 +00003227- Issue #5920: For float.__format__, change the behavior with the
3228 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3229 to be like 'g' but with at least one decimal point and with a
3230 default precision of 12. Previously, the behavior the same but with
3231 a default precision of 6. This more closely matches str(), and
3232 reduces surprises when adding alignment flags to the empty
3233 presentation type. This also affects the new complex.__format__ in
3234 the same way.
3235
Martin v. Löwis011e8422009-05-05 04:43:17 +00003236- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
3237
R. David Murrayb18500d2009-05-04 22:59:07 +00003238- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3239 shadowed by classtype's, even if it was None. property now
3240 inserts the __doc__ into the subclass instance __dict__.
3241
Antoine Pitrou244651a2009-05-04 18:56:13 +00003242- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3243 sequences. Patch by Nick Barnes and Victor Stinner.
3244
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003245- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003246
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003247- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3248 received a new method, detach(). detach() disconnects the underlying stream
3249 from the buffer or text IO and returns it.
3250
Mark Dickinson33841c32009-05-01 15:37:04 +00003251- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3252 floats with absolute value over 1e50. Also remove length
3253 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3254 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003255
Eric Smith741191f2009-05-06 13:08:15 +00003256- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003257 format(complex(1, 2./3), '.5') now produces a sensible result.
3258
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003259- Issue #5864: Fix empty format code formatting for floats so that it
3260 never gives more than the requested number of significant digits.
3261
Eric Smith6dc46f52009-04-27 20:39:49 +00003262- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3263 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3264
Eric Smithcc32a112009-04-26 21:35:14 +00003265- Issue #5835: Deprecate PyOS_ascii_formatd.
3266
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003267- Issue #4971: Fix titlecase for characters that are their own
3268 titlecase, but not their own uppercase.
3269
Benjamin Peterson193152c2009-04-25 01:08:45 +00003270- Issue #5283: Setting __class__ in __del__ caused a segfault.
3271
Mark Dickinsonad476da2009-04-23 19:14:16 +00003272- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3273 z involves nans, infs or negative zeros.
3274
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003275- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003276
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003277- Issue #1869 (and many duplicates): make round(x, n) correctly
3278 rounded for a float x, by using the decimal <-> binary conversions
3279 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3280 consistently agrees with format(x, '.2f').
3281
Benjamin Petersonae937c02009-04-18 20:54:08 +00003282- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3283 some builtin types.
3284
Eric Smith0923d1d2009-04-16 20:16:10 +00003285- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3286
Eric Smith35e84722009-04-16 20:21:28 +00003287- Issue #5515: str.format() type 'n' combined with commas and leading
3288 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003289
3290- Implement PEP 378, Format Specifier for Thousands Separator, for
3291 floats.
3292
Mark Dickinson3370cce2009-04-17 22:40:53 +00003293- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003294 1e11, not 1e12. This avoids printing 13 significant digits in
3295 situations where only 12 of them are correct. Example problem
3296 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3297 long time.)
3298
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003299- Issue #1580: On most platforms, use a 'short' float repr: for a
3300 finite float x, repr(x) now outputs a string based on the shortest
3301 sequence of decimal digits that rounds to x. Previous behaviour was
3302 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003303 Another minor difference is that the new repr switches to
3304 exponential notation at 1e16 instead of the previous 1e17; this
3305 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003306
3307 There's a new sys attribute sys.float_repr_style, which takes
3308 the value 'short' to indicate that we're using short float repr,
3309 and 'legacy' if the short float repr isn't available for one
3310 reason or another.
3311
3312 The float repr change involves incorporating David Gay's 'perfect
3313 rounding' code into the Python core (it's in Python/dtoa.c). As a
3314 secondary consequence, all string-to-float and float-to-string
3315 conversions (including all float formatting operations) will be
3316 correctly rounded on these platforms.
3317
Georg Brandl5f90d792010-08-01 22:31:05 +00003318 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003319 this change does not apply.
3320
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003321- Issue #5759: float() didn't call __float__ on str subclasses.
3322
Georg Brandlabc38772009-04-12 15:51:51 +00003323- The string.maketrans() function is deprecated; there is a new static method
3324 maketrans() on the bytes and bytearray classes. This removes confusion about
3325 the types string.maketrans() is supposed to work with, and mirrors the
3326 methods available on the str class.
3327
R. David Murraydc6da8a2009-04-09 22:16:43 +00003328- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3329 its clarity and its speed.
3330
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003331- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003332 to avoid compiler warnings.
3333
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003334- Issue #3739: The unicode-internal encoder now reports the number of characters
3335 consumed like any other encoder (instead of the number of bytes).

3473
Benjamin Peterson7fe98532009-04-02 00:33:55 +00003474- Issue #5499: The 'c' code for argument parsing functions now only accepts a
3475 byte, and the 'C' code only accepts a unicode character.
3476
Georg Brandl406b3d82009-04-11 21:24:37 +00003477- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
3478 when hitting the recursion limit under certain circumstances.
3479
Brett Cannon0759dd62009-04-01 18:13:07 +00003480- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
3481
Georg Brandlab6f2f62009-03-31 04:16:10 +00003482- Fix a segfault when running test_exceptions with coverage, caused by
3483 insufficient checks in accessors of Exception.__context__.
3484
Guido van Rossum0ad59d42009-03-30 22:01:35 +00003485- Issue #5604: non-ASCII characters in module name passed to
3486 imp.find_module() were converted to UTF-8 while the path is
3487 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00003489- Issue #5126: str.isprintable() returned False for space characters.
3490
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00003491- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
3492 the end sys.path, for compatibility with the system install of Python.
3493
Antoine Pitrou3a652b12009-03-23 18:52:06 +00003494- Issue #4688: Add a heuristic so that tuples and dicts containing only
3495 untrackable objects are not tracked by the garbage collector. This can
3496 reduce the size of collections and therefore the garbage collection overhead
3497 on long-running programs, depending on their particular use of datatypes.
3498
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00003499- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

3504 2**15 for the internal representation of integers, for performance
3505 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
3506 --enable-big-digits option to configure, which overrides the
3507 default. Add sys.int_info structseq to provide information about
3508 the internal format.

3511 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
3512 and sizeof(Py_UNICODE) == 2.
3513
Eric Smith8ec90442009-03-14 12:29:34 +00003514- Issue #5237: Allow auto-numbered fields in str.format(). For

3516
Antoine Pitrou652e7072009-03-13 19:25:20 +00003517- Issue #5392: when a very low recursion limit was set, the interpreter would
3518 abort with a fatal error after the recursion limit was hit twice.
3519
Matthias Klose042f1332009-04-04 14:32:42 +00003520- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

3566
Lars Gustäbel42e00912009-03-22 20:34:29 +00003567- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
3568 forever on incomplete input. That caused tarfile.open() to hang when used
3569 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
3570 partial bzip2 compressed data.
3571
Mark Dickinson79f52032009-03-17 23:12:51 +00003572- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +00003589- Issue #5463: In struct module, remove deprecated overflow wrapping
3590 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00003591 struct.error instead of returning b'\xff\xff\xff\xff'. The
3592 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
3593 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00003620- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
3621 it now forces its argument to double before testing for infinity.
3622
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00003623- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
3624 returns a non-number type.
3625
Benjamin Peterson87618552009-02-08 15:00:52 +00003626- Issue #5182: Removed memoryview.__str__.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00003633- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00003634 were suppressing all exceptions. These include list() and bytearray().
3635
Mark Dickinson1124e712009-01-28 21:25:58 +00003636- Issue #4707: round(x, n) now returns an integer if x is an integer.
3637 Previously it returned a float.
3638

3640 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3641 evaluation loop is compiled with a new dispatch mechanism which gives
3642 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003657- Issue #4935: The overflow checking code in the expandtabs() method common
3658 to str, bytes and bytearray could be optimized away by the compiler, letting
3659 the interpreter segfault instead of raising an error.
3660
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003661- Issue #3720: Fix a crash when an iterator modifies its class and removes its

3673 common cases are optimized thanks to a dedicated fast path and a moderate
3674 amount of loop unrolling.
3675
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003676- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3677 collecting the oldest generation) so that allocating lots of objects without
3678 destroying them does not show quadratic performance. Based on a proposal by

Antoine Pitrou8043cf82009-01-09 19:54:29 +00003683 having been closed (for instance, a read() call could return some
3684 previously buffered data). Patch by Dmitry Vasiliev.
3685
Antoine Pitrou05608432009-01-09 18:53:14 +00003686- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3687 flag to work properly. Furthermore, when specifying -u, the text stdout
3688 and stderr streams have line-by-line buffering enabled (the default being
3689 to buffer arbitrary chunks of data).
3690
Raymond Hettinger35631532009-01-09 03:58:09 +00003691- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3692 instead of ints (reducing its size from 4 to 8 times thereby reducing
3693 Python's overall memory).
3694
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003695- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3696 an existing .py counterpart, override the co_filename attributes of all
3697 code objects if the original filename is obsolete (which can happen if the
3698 file has been renamed, moved, or if it is accessed through different paths).
3699 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3700
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003701- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3702 one byte. Also fixes the meaning of len() so that it returns the number of
3703 items, rather than the size in bytes.
3704
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003705- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3706
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003707- Issue #4747: When the terminal does not use utf-8, executing a script with

3715
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003716- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3717 where the tp_hash and tp_dict slots are both NULL.
3718
Georg Brandlccc47b62008-12-28 11:44:14 +00003719- Issue #4759: None is now allowed as the first argument of
3720 bytearray.translate(). It was always allowed for bytes.translate().
3721
Skip Montanaro80072cb2008-12-23 03:51:14 +00003722- Added test case to ensure attempts to read from a file opened for writing
3723 fail.

3773 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00004093- Issue #5008: When a file is opened in append mode with the new IO library,
4094 do an explicit seek to the end of file (so that e.g. tell() returns the

4126 appropriately when it is being used via socket.makefile() objects
4127 rather than delaying the close by waiting for garbage collection to do it.
