14
Victor Stinner94908bb2010-08-18 21:23:25 +000015- Issue #8622: Add PYTHONFSENCODING environment variable to override the
16 filesystem encoding.
17
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +000018- Issue #5127: The C functions that access the Unicode Database now accept and
19 return characters from the full Unicode range, even on narrow unicode builds
20 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
21 in Python is that unicodedata.numeric() now returns the correct value for
22 large code points, and repr() may consider more characters as printable.
23
Victor Stinner6c00c142010-08-17 23:37:11 +000024- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
25 as a unicode object, instead of a byte string. Function needed to support
26 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
27 function.
28
Victor Stinner6961bd62010-08-17 22:26:51 +000029- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

34 for the module file to be executed with the -m command line option.
35
Victor Stinner79766632010-08-16 17:36:42 +000036- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions

38 sys.stderr.
39
Victor Stinner47fcb5b2010-08-13 23:59:58 +000040- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
41 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize();
42 str objects are output as-is.
43
Antoine Pitrou042b1282010-08-13 21:15:58 +000044- Issue #9203: Computed gotos are now enabled by default on supported
45 compilers (which are detected by the configure script). They can still
46 be disable selectively by specifying --without-computed-gotos.
47
Victor Stinner4a2b7a12010-08-13 14:03:48 +000048- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx()
49 but use PyUnicode_FromFormatV() to format the warning message.
50
Florent Xiclunaeb6f3ea2010-08-08 22:07:16 +000051- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
52 of an array.
53
Antoine Pitroubddc9fe2010-08-08 20:46:42 +000054- Issue #5319: Print an error if flushing stdout fails at interpreter
55 shutdown.
56
Mark Dickinson388122d2010-08-04 20:56:28 +000057- Issue #9337: The str() of a float or complex number is now identical
58 to its repr().
59
Mark Dickinson5b65df72010-08-01 10:41:49 +000060- Issue #9416: Fix some issues with complex formatting where the
61 output with no type specifier failed to match the str output:
62
63 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
64 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

307-----------------
308
Victor Stinner8182b712010-07-28 00:40:58 +0000309- Issue #8991: convertbuffer() rejects discontigious buffers.
310
Antoine Pitrou1ac745b2010-07-11 12:12:00 +0000311- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
312 compiler.
313
Benjamin Petersonccabcd42010-07-07 20:54:01 +0000314- Issue #8413: structsequence now subclasses tuple.
315
Ezio Melotti57221d02010-07-01 07:32:02 +0000316- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000317 start byte and the continuation byte(s) are now considered invalid, instead of
318 the number of bytes specified by the start byte. E.g.:
319 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
320 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
321 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
322 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +0000323
Georg Brandl62069d32010-07-31 08:56:11 +0000324- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
325 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +0000326
Benjamin Peterson88968ad2010-06-25 19:30:21 +0000327- Be more specific in error messages about positional arguments.
328
Victor Stinner4aae1eb2010-06-24 22:08:25 +0000329- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
330 objects, as described in the documentation.
331
Victor Stinner0fe25a42010-06-17 23:08:50 +0000332- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +0000333 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
Victor Stinner2cd12522010-06-17 23:17:37 +0000334 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +0000335
Georg Brandl62069d32010-07-31 08:56:11 +0000336- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
337 dealing with unary minus applied to a constant. The removed code was mutating
338 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +0000339
Victor Stinner554f3f02010-06-16 23:33:54 +0000340- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000341 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000342 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000343 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000344
Victor Stinner25e8ec42010-06-25 00:02:38 +0000345- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
346 "w*" format instead. Add tests for "w*" format.
347
Victor Stinner06e49dd2010-06-13 18:21:50 +0000348- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000349 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +0000350 string formats.
351
Georg Brandl62069d32010-07-31 08:56:11 +0000352- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000353 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
354 location of the raised exception.
355
Victor Stinner313a1202010-06-11 23:56:51 +0000356- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
357 filenames and enable os.fsencode().
358
Benjamin Peterson285a6892010-06-22 19:21:52 +0000359- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
360
Georg Brandl62069d32010-07-31 08:56:11 +0000361- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
362 interpreter with characters outside the Basic Multilingual Plane (higher than
363 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000364
Georg Brandl62069d32010-07-31 08:56:11 +0000365- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
366 TypeError instead of giving a DeprecationWarning when a float is parsed using
367 the 'L' code (for long long). (All other integer codes already raise
368 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000369
Victor Stinner600d3be2010-06-10 12:00:55 +0000370- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
371 enable shortcuts for upper case encoding name. Add also a shortcut for
372 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
373
Georg Brandl62069d32010-07-31 08:56:11 +0000374- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
375 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000376
377- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000378 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000379 like bytearray.
380
Georg Brandl62069d32010-07-31 08:56:11 +0000381- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000382 used anymore and it was never documented.
383
Georg Brandl62069d32010-07-31 08:56:11 +0000384- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +0000385
Georg Brandl62069d32010-07-31 08:56:11 +0000386- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
387 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000388
Georg Brandl62069d32010-07-31 08:56:11 +0000389- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
390 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
391 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
392 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000393
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000394- Issue #8748: Fix two issues with comparisons between complex and integer
395 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000396 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
397 (2) The comparison raised an OverflowError for large integers, leading to
398 unpredictable exceptions when combining integers and complex objects in sets
399 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000400
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000401- Issue #8766: Initialize _warnings module before importing the first module.
402 Fix a crash if an empty directory called "encodings" exists in sys.path.
403
Victor Stinner9ca9c252010-05-19 16:53:30 +0000404- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +0000405 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000406 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000407
Georg Brandl62069d32010-07-31 08:56:11 +0000408- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
409 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000410
Victor Stinnerae6265f2010-05-15 16:27:27 +0000411- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
412 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000413 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000414 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000415
Victor Stinner59e62db2010-05-15 13:14:32 +0000416- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000417 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000418
Victor Stinnerb744ba12010-05-15 12:27:16 +0000419- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000420 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000421 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
422
Victor Stinner0964ee12010-04-30 16:48:45 +0000423- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000424 PyUnicode_FromString() to support surrogates in the filename and use the right
425 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000426
Georg Brandl8569e582010-05-19 20:57:08 +0000427- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
428
Georg Brandl62069d32010-07-31 08:56:11 +0000429- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000430
Benjamin Petersonfb886362010-04-24 18:21:17 +0000431- Issue #8419: Prevent the dict constructor from accepting non-string keyword
432 arguments.
433
Victor Stinner14284c22010-04-23 12:02:30 +0000434- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +0000435 indirectly Python signal handlers anymore because mywrite() ignores exceptions
436 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +0000437
Victor Stinner31be90b2010-04-22 19:38:16 +0000438- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +0000439 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +0000440
Georg Brandl62069d32010-07-31 08:56:11 +0000441- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
442 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +0000443
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000444- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +0000445 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
446 compared to the dynamic memory allocation fallback. Patch by Charles-François
447 Natali.
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000448
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000449- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000528- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +0000529 where the right hand operand is a set of constants, by turning the set into a
530 frozenset and pre-building it as a constant. The comparison operation is made
531 against the constant instead of building a new set each time it is executed (a
532 similar optimization already existed which turned a list of constants into a
533 pre-built tuple). Patch and additional tests by Dave Malcolm.

540 including: (1) a serious 'wrong output' bug that could occur for long (> 40
541 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
542 parsing certain long numeric strings corresponding to subnormal values, (3) a
543 memory leak for some values large enough to cause overflow, and (4) a number
544 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +0000558- Issue #1811: improve accuracy and cross-platform consistency for true division
559 of integers: the result of a/b is now correctly rounded for ints a and b (at
560 least on IEEE 754 platforms), and in particular does not depend on the
561 internal representation of an int.

588 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
589 long but the length of the range did not. Also fix several cases where
590 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
591 reversed(range(a, b, c)) with large arguments.

704
Mark Dickinsone6fc7402010-08-06 18:55:26 +0000705- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
706 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

Georg Brandl62069d32010-07-31 08:56:11 +00001234 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1235 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00001236
Raymond Hettingerc50846a2010-04-05 18:56:31 +00001237- Add functools.total_ordering() and functools.cmp_to_key().
1238
Georg Brandl62069d32010-07-31 08:56:11 +00001239- Issue #8257: The Decimal construct now accepts a float instance directly,
1240 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00001241
1242 >>> Decimal(1.1)
1243 Decimal('1.100000000000000088817841970012523233890533447265625')
1244
Georg Brandl62069d32010-07-31 08:56:11 +00001245- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1246 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00001247
Georg Brandl62069d32010-07-31 08:56:11 +00001248- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1249 InvalidOperation instead of returning False. (Comparisons involving a quiet
1250 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1251 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00001252
Georg Brandl62069d32010-07-31 08:56:11 +00001253- Issue #2531: Comparison operations between floats and Decimal instances now
1254 return a result based on the numeric values of the operands; previously they
1255 returned an arbitrary result based on the relative ordering of id(float) and
1256 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1257 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00001258
Raymond Hettinger9c01e442010-04-03 10:32:58 +00001259- Added a subtract() method to collections.Counter().
1260
Barry Warsawd5f9bf52010-03-31 21:36:22 +00001261- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001262 argument `-` which tells it to read files to compile from stdin. Each line is
1263 read on demand and the named file is compiled immediately. (Original patch by
1264 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00001265
Florent Xicluna806d8cf2010-03-30 19:34:18 +00001266- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1267 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00001268 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna806d8cf2010-03-30 19:34:18 +00001269
Georg Brandl62069d32010-07-31 08:56:11 +00001270- Comparisons using one of <, <=, >, >= between a complex instance and a
1271 Fractions instance now raise TypeError instead of returning True/False. This
1272 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1273 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001275- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Florent Xiclunafd1b0932010-03-28 00:25:02 +00001279- Issue #8205: Remove the "Modules" directory from sys.path when Python is
1280 running from the build directory (POSIX only).
1281
Antoine Pitrou910bd512010-03-22 20:11:09 +00001282- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00001283 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1284 silenced.

Georg Brandl62069d32010-07-31 08:56:11 +00001286- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1287 is running in WOW64 mode on 64 bit Windows.
R. David Murrayca2edce2010-03-22 17:48:48 +00001288
Antoine Pitrou3c0fac22010-03-26 19:36:14 +00001289- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1290 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1291 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +00001292
Victor Stinnere3a1f6d2010-03-22 01:58:35 +00001293- Issue #4282: Fix the main function of the profile module for a non-ASCII

1300
Benjamin Peterson00888932010-03-18 22:37:38 +00001301- Issue #8168: py_compile now handles files with utf-8 BOMS.
1302
Benjamin Peterson689a5582010-03-18 22:29:52 +00001303- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
1304 detected.
1305
Martin v. Löwis4b003072010-03-16 13:19:21 +00001306- Issue #6716/2: Backslash-replace error output in compilall.

1309 with Tcl/Tk-8.5.
1310
Georg Brandl62069d32010-07-31 08:56:11 +00001311- Issue #8140: extend compileall to compile single files. Add -i option.

Georg Brandl62069d32010-07-31 08:56:11 +00001313- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
1314 locale.
Matthias Klose82f60912010-03-15 13:46:04 +00001315
Georg Brandl62069d32010-07-31 08:56:11 +00001316- The internals of the subprocess module on POSIX systems have been replaced by
1317 an extension module (_posixsubprocess) so that the fork()+exec() can be done
1318 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00001319
Georg Brandl62069d32010-07-31 08:56:11 +00001320- subprocess.Popen now has restore_signals and start_new_session features. The
1321 default of restore_signals=True is a new behavior compared to earlier Python
1322 versions. This means that signals such as SIGPIPE are not ignored by default
1323 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00001324
Florent Xiclunaf15351d2010-03-13 23:24:31 +00001325- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

Gerhard Häringf9cee222010-03-05 15:20:03 +00001337- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
1338 bugs and allows loading SQLite extensions from shared libraries.
1339
Ezio Melottida227042010-03-14 11:51:00 +00001340- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Georg Brandl62069d32010-07-31 08:56:11 +00001384- Issue #7633: In the decimal module, Context class methods (with the exception
1385 of canonical and is_canonical) now accept instances of int and long wherever a
1386 Decimal instance is accepted, and implicitly convert that argument to Decimal.
1387 Previously only some arguments were converted.

1405 specified, rather than fall through to AF_PACKET (in the `socket` module).
Georg Brandl62069d32010-07-31 08:56:11 +00001406 Also, raise ValueError rather than TypeError when an unknown TIPC address type
1407 is specified. Patch by Brian Curtin.

Georg Brandl62069d32010-07-31 08:56:11 +00001409- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
1410 position when calling `truncate()`. It would previously change the file
1411 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001412 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1413
Antoine Pitroua32f9a22010-01-27 21:18:57 +00001414- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00001415 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
1416 archive. The new implementation is significantly faster and can be wrapped in
1417 a :class:`io.BufferedReader` object for more speedups. It also solves an
1418 issue where interleaved calls to `read()` and `readline()` give wrong results.
1419 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00001754- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00001755 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
1756 PyPycLoader inherit from this class and provide implementations in relation to
1757 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00001758
Brett Cannon64ef00f2009-07-20 03:19:18 +00001759- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

1809
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001810- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00001811 compared to other unix systems. In particular, os.getgroups() does not reflect
1812 any changes made using os.setgroups() but basicly always returns the same
1813 information as the id command. os.getgroups() can now return more than 16
1814 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001815

Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00001838
Georg Brandl62069d32010-07-31 08:56:11 +00001839- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
1840 Prior to this change, timezone adjustment in utctimetuple() could produce
1841 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
1842 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00001844- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
1845 directive. When the ``%z`` directive is present in the format string, an
1846 aware ``datetime`` object is returned with ``tzinfo`` bound to a
1847 ``datetime.timezone`` instance constructed from the parsed offset. If both
1848 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
1849 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001851- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00001852 implementing ``datetime.tzinfo`` interface. Instances of the new class,
1853 ``datetime.timezone``, return fixed name and UTC offset from their
1854 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
1855 returns ``None``. A class attribute, ``utc`` contains an instance
1856 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00001883 the result is now always correctly rounded, and is equivalent to ``td /

1893 integer format code, struct.pack first attempts to convert the non-integer

2468 a PendingDeprecation warning.
2469
Eric Smith63376222009-05-05 14:04:18 +00002470- Issue #5920: For float.__format__, change the behavior with the
2471 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2472 to be like 'g' but with at least one decimal point and with a
2473 default precision of 12. Previously, the behavior the same but with
2474 a default precision of 6. This more closely matches str(), and
2475 reduces surprises when adding alignment flags to the empty
2476 presentation type. This also affects the new complex.__format__ in
2477 the same way.
2478
Martin v. Löwis011e8422009-05-05 04:43:17 +00002479- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2480
R. David Murrayb18500d2009-05-04 22:59:07 +00002481- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2482 shadowed by classtype's, even if it was None. property now
2483 inserts the __doc__ into the subclass instance __dict__.
2484
Antoine Pitrou244651a2009-05-04 18:56:13 +00002485- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00002490- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2491 received a new method, detach(). detach() disconnects the underlying stream
2492 from the buffer or text IO and returns it.
2493
Mark Dickinson33841c32009-05-01 15:37:04 +00002494- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2495 floats with absolute value over 1e50. Also remove length
2496 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2497 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002498
Eric Smith741191f2009-05-06 13:08:15 +00002499- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002500 format(complex(1, 2./3), '.5') now produces a sensible result.
2501
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002502- Issue #5864: Fix empty format code formatting for floats so that it
2503 never gives more than the requested number of significant digits.
2504
Eric Smith6dc46f52009-04-27 20:39:49 +00002505- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

2512
Benjamin Peterson193152c2009-04-25 01:08:45 +00002513- Issue #5283: Setting __class__ in __del__ caused a segfault.
2514
Mark Dickinsonad476da2009-04-23 19:14:16 +00002515- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2516 z involves nans, infs or negative zeros.
2517
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002518- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002519
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002520- Issue #1869 (and many duplicates): make round(x, n) correctly
2521 rounded for a float x, by using the decimal <-> binary conversions
2522 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2523 consistently agrees with format(x, '.2f').
2524
Benjamin Petersonae937c02009-04-18 20:54:08 +00002525- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2526 some builtin types.
2527
Eric Smith0923d1d2009-04-16 20:16:10 +00002528- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2529
Eric Smith35e84722009-04-16 20:21:28 +00002530- Issue #5515: str.format() type 'n' combined with commas and leading
2531 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002532
2533- Implement PEP 378, Format Specifier for Thousands Separator, for
2534 floats.
2535
Mark Dickinson3370cce2009-04-17 22:40:53 +00002536- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002537 1e11, not 1e12. This avoids printing 13 significant digits in
2538 situations where only 12 of them are correct. Example problem
2539 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2540 long time.)
2541
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002542- Issue #1580: On most platforms, use a 'short' float repr: for a
2543 finite float x, repr(x) now outputs a string based on the shortest
2544 sequence of decimal digits that rounds to x. Previous behaviour was
2545 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002546 Another minor difference is that the new repr switches to
2547 exponential notation at 1e16 instead of the previous 1e17; this
2548 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002549
2550 There's a new sys attribute sys.float_repr_style, which takes
2551 the value 'short' to indicate that we're using short float repr,
2552 and 'legacy' if the short float repr isn't available for one
2553 reason or another.
2554
2555 The float repr change involves incorporating David Gay's 'perfect
2556 rounding' code into the Python core (it's in Python/dtoa.c). As a
2557 secondary consequence, all string-to-float and float-to-string
2558 conversions (including all float formatting operations) will be
2559 correctly rounded on these platforms.
2560
Georg Brandl5f90d792010-08-01 22:31:05 +00002561 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002562 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002564- Issue #5759: float() didn't call __float__ on str subclasses.
2565
Georg Brandlabc38772009-04-12 15:51:51 +00002566- The string.maketrans() function is deprecated; there is a new static method
2567 maketrans() on the bytes and bytearray classes. This removes confusion about
2568 the types string.maketrans() is supposed to work with, and mirrors the
2569 methods available on the str class.
2570
R. David Murraydc6da8a2009-04-09 22:16:43 +00002571- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Benjamin Peterson8f76b492009-04-03 22:22:42 +00002715- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
2716
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002717- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2718 byte, and the 'C' code only accepts a unicode character.
2719
Georg Brandl406b3d82009-04-11 21:24:37 +00002720- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2721 when hitting the recursion limit under certain circumstances.
2722
Brett Cannon0759dd62009-04-01 18:13:07 +00002723- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.

Georg Brandlab6f2f62009-03-31 04:16:10 +00002725- Fix a segfault when running test_exceptions with coverage, caused by
2726 insufficient checks in accessors of Exception.__context__.
2727
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002728- Issue #5604: non-ASCII characters in module name passed to

2736
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002737- Issue #4688: Add a heuristic so that tuples and dicts containing only
2738 untrackable objects are not tracked by the garbage collector. This can
2739 reduce the size of collections and therefore the garbage collection overhead
2740 on long-running programs, depending on their particular use of datatypes.

2745
Mark Dickinsonbd792642009-03-18 20:06:12 +00002746- Issue #4258: Make it possible to use base 2**30 instead of base
2747 2**15 for the internal representation of integers, for performance
2748 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2749 --enable-big-digits option to configure, which overrides the
2750 default. Add sys.int_info structseq to provide information about
2751 the internal format.
2752
Mark Dickinson081dfee2009-03-18 14:47:41 +00002753- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2754 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2755 and sizeof(Py_UNICODE) == 2.
2756
Eric Smith8ec90442009-03-14 12:29:34 +00002757- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00002863- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2864 it now forces its argument to double before testing for infinity.
2865
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002866- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002875
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002876- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002877 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002879- Issue #4707: round(x, n) now returns an integer if x is an integer.
2880 Previously it returned a float.
2881
Antoine Pitroub52ec782009-01-25 16:34:23 +00002882- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2883 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2884 evaluation loop is compiled with a new dispatch mechanism which gives
2885 speedups of up to 20%, depending on the system, on various benchmarks.
2886
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002887- Issue #4874: Most builtin decoders now reject unicode input.

2895 optional module state data.
2896
Mark Dickinson8055afd2009-01-17 10:04:45 +00002897- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2898 type to (void *).
2899
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002900- Issue #4935: The overflow checking code in the expandtabs() method common
2901 to str, bytes and bytearray could be optimized away by the compiler, letting
2902 the interpreter segfault instead of raising an error.
2903
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002904- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2905 __next__ method.
2906
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002907- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2908 function no longer attempt to call the __long__ slot to convert an object
2909 to an integer. Only the __int__ and __trunc__ slots are examined.
2910
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002911- Issue #4893: Use NT threading on CE.
2912

2914
Antoine Pitrouab868312009-01-10 15:40:25 +00002915- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2916 common cases are optimized thanks to a dedicated fast path and a moderate
2917 amount of loop unrolling.
2918
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002919- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2920 collecting the oldest generation) so that allocating lots of objects without
2921 destroying them does not show quadratic performance. Based on a proposal by
2922 Martin von Löwis at
2923 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2924
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002925- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002926 having been closed (for instance, a read() call could return some
2927 previously buffered data). Patch by Dmitry Vasiliev.
2928
Antoine Pitrou05608432009-01-09 18:53:14 +00002929- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2930 flag to work properly. Furthermore, when specifying -u, the text stdout
2931 and stderr streams have line-by-line buffering enabled (the default being
2932 to buffer arbitrary chunks of data).
2933
Raymond Hettinger35631532009-01-09 03:58:09 +00002934- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2935 instead of ints (reducing its size from 4 to 8 times thereby reducing
2936 Python's overall memory).
2937
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002938- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2939 an existing .py counterpart, override the co_filename attributes of all
2940 code objects if the original filename is obsolete (which can happen if the
2941 file has been renamed, moved, or if it is accessed through different paths).
2942 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2943
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002944- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2945 one byte. Also fixes the meaning of len() so that it returns the number of
2946 items, rather than the size in bytes.
2947
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002948- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2949
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002950- Issue #4747: When the terminal does not use utf-8, executing a script with
2951 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2952
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002953- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002954 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002955
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002956- Issue #3680: Reference cycles created through a dict, set or deque iterator
2957 did not get collected.
2958
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002959- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2960 where the tp_hash and tp_dict slots are both NULL.
2961
Georg Brandlccc47b62008-12-28 11:44:14 +00002962- Issue #4759: None is now allowed as the first argument of
2963 bytearray.translate(). It was always allowed for bytes.translate().
2964
Skip Montanaro80072cb2008-12-23 03:51:14 +00002965- Added test case to ensure attempts to read from a file opened for writing
2966 fail.
2967
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002968- Issue #3106: Speedup some comparisons (str/str and int/int).

2972
Antoine Pitrou621601a2008-12-17 23:18:19 +00002973- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2974 print elapsed times, not only when some objects are uncollectable /
2975 unreachable. Original patch by Neil Schemenauer.
2976
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002977- Issue #3439: Add a bit_length method to int.
2978
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002979- Issue #2173: When getting device encoding, check that return value of
2980 nl_langinfo is not the empty string. This was causing silent build
2981 failures on OS X.
2982
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002983- Issue #4597: Fixed several opcodes that weren't always propagating
2984 exceptions.
2985
2986- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002987 context manager returns a value that cannot be converted to a bool.
2988
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002989- Issue #4445: Replace "sizeof(PyBytesObject)" with
2990 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2991 bytes instances. On a typical machine this saves 3 bytes of memory
2992 (on average) per allocation of a bytes instance.
2993
Christian Heimesa872de52008-12-05 08:26:55 +00002994- Issue #4533: File read operation was dreadfully slow due to a slowly
2995 growing read buffer. Fixed by using the same growth rate algorithm as
2996 Python 2.x.
2997
Antoine Pitrou5504e892008-12-06 21:27:53 +00002998- Issue #4509: Various issues surrounding resize of bytearray objects to
2999 which there are buffer exports (e.g. memoryview instances).
3000
Georg Brandlf9734072008-12-07 15:30:06 +00003001- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3002 method on file objects with closefd=False. The file descriptor is still
3003 kept open but the file object behaves like a closed file. The ``FileIO``
3004 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00003006- Issue #4569: Interpreter crash when mutating a memoryview with an item size

3014 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3015 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3016 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00003618- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3619 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00003621- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3622 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3623 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3624 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00003626- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003627 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003628 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00003630- Issue #5083: New 'gui' resource for regrtest.
