Georg Brandl4fbc0d82010-11-13 13:25:40 +0000282 incorrectly validated some non-compliant applications as WSGI compliant; if
283 your app validates with Python <3.2b1+, but not on this version, it is likely
284 the case that your app was not compliant.)

Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000540- Issue #9930: Remove bogus subtype check that was causing (e.g.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000545- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
546 threads are still running. Instead, reinitialize the GIL on a second call to
547 Py_Initialize().
548
Georg Brandl27a28582010-10-10 09:49:21 +0000549- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +0000558- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
559 with a non-empty format string. This is an effort to future-proof user
560 code. If a derived class does not currently implement __format__ but later
561 adds its own __format__, it would most likely break user code that had
562 supplied a format string. This will be changed to a DeprecationWaring in
563 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +0000565- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
566 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
567 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000569- Issue #9210: Configure option --with-wctype-functions was removed. Using the
570 functions from the libc caused the methods .upper() and lower() to become
571 locale aware and created subtly wrong results.
572
Georg Brandl27a28582010-10-10 09:49:21 +0000573- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000576- Issue #4617: Previously it was illegal to delete a name from the local
577 namespace if it occurs as a free variable in a nested block. This limitation
578 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
579
Georg Brandl27a28582010-10-10 09:49:21 +0000580- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
581 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
582 Also, the "backslashreplace" error handler now joins surrogate pairs into a
583 single character on UCS-2 builds.

587 memoryview), and gain support for the context management protocol.
588
Antoine Pitrou079ce542010-09-08 12:37:10 +0000589- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +0000618- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000619 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000620 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000621 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +0000646 retry the select() loop instead of bailing out. This is because select() can

975 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000976
977 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Victor Stinner8182b712010-07-28 00:40:58 +00001304- Issue #8991: convertbuffer() rejects discontigious buffers.
1305

1310
Ezio Melotti57221d02010-07-01 07:32:02 +00001311- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001312 start byte and the continuation byte(s) are now considered invalid, instead of
1313 the number of bytes specified by the start byte. E.g.:
1314 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1315 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1316 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1317 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00001318
Georg Brandl62069d32010-07-31 08:56:11 +00001319- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
1320 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00001321
Benjamin Peterson88968ad2010-06-25 19:30:21 +00001322- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00001331- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
1332 dealing with unary minus applied to a constant. The removed code was mutating
1333 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00001334
Victor Stinner554f3f02010-06-16 23:33:54 +00001335- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00001336 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00001337 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001338 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00001339
Victor Stinner25e8ec42010-06-25 00:02:38 +00001340- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
1341 "w*" format instead. Add tests for "w*" format.
1342
Victor Stinner06e49dd2010-06-13 18:21:50 +00001343- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00001344 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00001345 string formats.
1346
Georg Brandl62069d32010-07-31 08:56:11 +00001347- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001348 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1349 location of the raised exception.
1350
Victor Stinner313a1202010-06-11 23:56:51 +00001351- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1352 filenames and enable os.fsencode().
1353
Benjamin Peterson285a6892010-06-22 19:21:52 +00001354- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
1355
Georg Brandl62069d32010-07-31 08:56:11 +00001356- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
1357 interpreter with characters outside the Basic Multilingual Plane (higher than
1358 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00001359
Georg Brandl62069d32010-07-31 08:56:11 +00001360- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1361 TypeError instead of giving a DeprecationWarning when a float is parsed using
1362 the 'L' code (for long long). (All other integer codes already raise
1363 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001364
Victor Stinner600d3be2010-06-10 12:00:55 +00001365- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1366 enable shortcuts for upper case encoding name. Add also a shortcut for
1367 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1368
Georg Brandl62069d32010-07-31 08:56:11 +00001369- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1370 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001371
1372- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001373 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001374 like bytearray.
1375
Georg Brandl62069d32010-07-31 08:56:11 +00001376- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001377 used anymore and it was never documented.
1378
Georg Brandl62069d32010-07-31 08:56:11 +00001379- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00001380
Georg Brandl62069d32010-07-31 08:56:11 +00001381- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
1382 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001383
Georg Brandl62069d32010-07-31 08:56:11 +00001384- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1385 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1386 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1387 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001388
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001389- Issue #8748: Fix two issues with comparisons between complex and integer
1390 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001391 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1392 (2) The comparison raised an OverflowError for large integers, leading to
1393 unpredictable exceptions when combining integers and complex objects in sets
1394 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001395
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001396- Issue #8766: Initialize _warnings module before importing the first module.
1397 Fix a crash if an empty directory called "encodings" exists in sys.path.
1398
Victor Stinner9ca9c252010-05-19 16:53:30 +00001399- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001400 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001401 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001402
Georg Brandl62069d32010-07-31 08:56:11 +00001403- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1404 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001405
Victor Stinnerae6265f2010-05-15 16:27:27 +00001406- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1407 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001408 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001409 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001410
Victor Stinner59e62db2010-05-15 13:14:32 +00001411- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001412 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001413
Victor Stinnerb744ba12010-05-15 12:27:16 +00001414- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001415 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001416 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1417
Victor Stinner0964ee12010-04-30 16:48:45 +00001418- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001419 PyUnicode_FromString() to support surrogates in the filename and use the right
1420 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00001421
Georg Brandl8569e582010-05-19 20:57:08 +00001422- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
1423
Georg Brandl62069d32010-07-31 08:56:11 +00001424- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00001425
Benjamin Petersonfb886362010-04-24 18:21:17 +00001426- Issue #8419: Prevent the dict constructor from accepting non-string keyword
1427 arguments.
1428
Victor Stinner14284c22010-04-23 12:02:30 +00001429- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00001430 indirectly Python signal handlers anymore because mywrite() ignores exceptions
1431 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00001435
Georg Brandl62069d32010-07-31 08:56:11 +00001436- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
1437 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00001438
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00001439- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00001440 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
1441 compared to the dynamic memory allocation fallback. Patch by Charles-François

Antoine Pitrou3060c452010-08-13 16:27:38 +00001831 simply clearing the entire cache on overflow to forgetting the least recently
1832 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001833 applications that use a lot of regular expressions and limits the impact of
1834 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002243- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2244 InvalidOperation instead of returning False. (Comparisons involving a quiet
2245 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2246 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00002248- Issue #2531: Comparison operations between floats and Decimal instances now
2249 return a result based on the numeric values of the operands; previously they
2250 returned an arbitrary result based on the relative ordering of id(float) and
2251 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2252 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002253
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002254- Added a subtract() method to collections.Counter().
2255
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002256- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002257 argument `-` which tells it to read files to compile from stdin. Each line is
2258 read on demand and the named file is compiled immediately. (Original patch by
2259 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00002261- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00002265- Comparisons using one of <, <=, >, >= between a complex instance and a
2266 Fractions instance now raise TypeError instead of returning True/False. This
2267 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2268 <=> complex, and complex <=> complex comparisons.

2276
Antoine Pitrou910bd512010-03-22 20:11:09 +00002277- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002278 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00002311- The internals of the subprocess module on POSIX systems have been replaced by
2312 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2313 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00002314
Georg Brandl62069d32010-07-31 08:56:11 +00002315- subprocess.Popen now has restore_signals and start_new_session features. The
2316 default of restore_signals=True is a new behavior compared to earlier Python
2317 versions. This means that signals such as SIGPIPE are not ignored by default
2318 in subprocesses launched by Python (Issue #1652).

Antoine Pitroua32f9a22010-01-27 21:18:57 +00002409- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00002410 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
2411 archive. The new implementation is significantly faster and can be wrapped in
2412 a :class:`io.BufferedReader` object for more speedups. It also solves an
2413 issue where interleaved calls to `read()` and `readline()` give wrong results.
2414 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002811- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002812 compared to other unix systems. In particular, os.getgroups() does not reflect
2813 any changes made using os.setgroups() but basicly always returns the same
2814 information as the id command. os.getgroups() can now return more than 16
2815 groups on MacOSX.

3171 threads could return successfully while some Thread objects were still
3172 referenced. This also introduces a new private function:

3406
Antoine Pitroue4501852009-05-14 18:55:55 +00003407- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
3408 library. This means, for example, that opening an UTF-16 text file in
3409 append mode doesn't add a BOM at the end of the file if the file isn't
3410 empty.
3411
R. David Murray74b89242009-05-13 17:33:03 +00003412- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
3413 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
3414 corrects a pydoc regression.
3415
Georg Brandl5f90d792010-08-01 22:31:05 +00003416- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00003417 now it does. This also means getfp method now returns the real fp.

3460Core and Builtins
3461-----------------
3462
Mark Dickinson865e01a2009-05-07 16:37:01 +00003463- Issue #5914: Add new C API function PyOS_string_to_double, and
3464 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3465
Eric Smith741191f2009-05-06 13:08:15 +00003466- Issue #3382: float.__format__, complex.__format__, and %-formatting
3467 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
3468 affects nan -> NAN and inf -> INF.
3469
Mark Hammond5a607a32009-05-06 08:04:54 +00003470- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
3471 in all operations, including splitdrive, split, etc. splitunc() now issues
3472 a PendingDeprecation warning.
3473
Eric Smith63376222009-05-05 14:04:18 +00003474- Issue #5920: For float.__format__, change the behavior with the
3475 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3476 to be like 'g' but with at least one decimal point and with a
3477 default precision of 12. Previously, the behavior the same but with
3478 a default precision of 6. This more closely matches str(), and
3479 reduces surprises when adding alignment flags to the empty
3480 presentation type. This also affects the new complex.__format__ in
3481 the same way.
3482
Martin v. Löwis011e8422009-05-05 04:43:17 +00003483- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
3484
R. David Murrayb18500d2009-05-04 22:59:07 +00003485- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3486 shadowed by classtype's, even if it was None. property now
3487 inserts the __doc__ into the subclass instance __dict__.
3488
Antoine Pitrou244651a2009-05-04 18:56:13 +00003489- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3490 sequences. Patch by Nick Barnes and Victor Stinner.
3491
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003492- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003493
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003494- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3495 received a new method, detach(). detach() disconnects the underlying stream
3496 from the buffer or text IO and returns it.
3497
Mark Dickinson33841c32009-05-01 15:37:04 +00003498- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3499 floats with absolute value over 1e50. Also remove length
3500 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3501 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003502
Eric Smith741191f2009-05-06 13:08:15 +00003503- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003504 format(complex(1, 2./3), '.5') now produces a sensible result.
3505
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003506- Issue #5864: Fix empty format code formatting for floats so that it
3507 never gives more than the requested number of significant digits.
3508
Eric Smith6dc46f52009-04-27 20:39:49 +00003509- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3510 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3511
Eric Smithcc32a112009-04-26 21:35:14 +00003512- Issue #5835: Deprecate PyOS_ascii_formatd.
3513
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003514- Issue #4971: Fix titlecase for characters that are their own
3515 titlecase, but not their own uppercase.
3516
Benjamin Peterson193152c2009-04-25 01:08:45 +00003517- Issue #5283: Setting __class__ in __del__ caused a segfault.
3518
Mark Dickinsonad476da2009-04-23 19:14:16 +00003519- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3520 z involves nans, infs or negative zeros.
3521
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003522- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003523
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003524- Issue #1869 (and many duplicates): make round(x, n) correctly
3525 rounded for a float x, by using the decimal <-> binary conversions
3526 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3527 consistently agrees with format(x, '.2f').
3528
Benjamin Petersonae937c02009-04-18 20:54:08 +00003529- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3530 some builtin types.
3531
Eric Smith0923d1d2009-04-16 20:16:10 +00003532- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3533
Eric Smith35e84722009-04-16 20:21:28 +00003534- Issue #5515: str.format() type 'n' combined with commas and leading
3535 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003536
3537- Implement PEP 378, Format Specifier for Thousands Separator, for
3538 floats.
3539
Mark Dickinson3370cce2009-04-17 22:40:53 +00003540- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003541 1e11, not 1e12. This avoids printing 13 significant digits in
3542 situations where only 12 of them are correct. Example problem
3543 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3544 long time.)
3545
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003546- Issue #1580: On most platforms, use a 'short' float repr: for a
3547 finite float x, repr(x) now outputs a string based on the shortest
3548 sequence of decimal digits that rounds to x. Previous behaviour was
3549 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003550 Another minor difference is that the new repr switches to
3551 exponential notation at 1e16 instead of the previous 1e17; this
3552 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003553
3554 There's a new sys attribute sys.float_repr_style, which takes
3555 the value 'short' to indicate that we're using short float repr,
3556 and 'legacy' if the short float repr isn't available for one
3557 reason or another.
3558
3559 The float repr change involves incorporating David Gay's 'perfect
3560 rounding' code into the Python core (it's in Python/dtoa.c). As a
3561 secondary consequence, all string-to-float and float-to-string
3562 conversions (including all float formatting operations) will be
3563 correctly rounded on these platforms.
3564
Georg Brandl5f90d792010-08-01 22:31:05 +00003565 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003566 this change does not apply.
3567
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003568- Issue #5759: float() didn't call __float__ on str subclasses.
3569
Georg Brandlabc38772009-04-12 15:51:51 +00003570- The string.maketrans() function is deprecated; there is a new static method
3571 maketrans() on the bytes and bytearray classes. This removes confusion about
3572 the types string.maketrans() is supposed to work with, and mirrors the
3573 methods available on the str class.
3574
R. David Murraydc6da8a2009-04-09 22:16:43 +00003575- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3576 its clarity and its speed.
3577
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003578- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003579 to avoid compiler warnings.
3580
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003581- Issue #3739: The unicode-internal encoder now reports the number of characters
3582 consumed like any other encoder (instead of the number of bytes).

3720
Benjamin Peterson7fe98532009-04-02 00:33:55 +00003721- Issue #5499: The 'c' code for argument parsing functions now only accepts a
3722 byte, and the 'C' code only accepts a unicode character.
3723
Georg Brandl406b3d82009-04-11 21:24:37 +00003724- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
3725 when hitting the recursion limit under certain circumstances.
3726
Brett Cannon0759dd62009-04-01 18:13:07 +00003727- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
3728
Georg Brandlab6f2f62009-03-31 04:16:10 +00003729- Fix a segfault when running test_exceptions with coverage, caused by
3730 insufficient checks in accessors of Exception.__context__.
3731
Guido van Rossum0ad59d42009-03-30 22:01:35 +00003732- Issue #5604: non-ASCII characters in module name passed to
3733 imp.find_module() were converted to UTF-8 while the path is
3734 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00003736- Issue #5126: str.isprintable() returned False for space characters.
3737
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00003738- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
3739 the end sys.path, for compatibility with the system install of Python.
3740
Antoine Pitrou3a652b12009-03-23 18:52:06 +00003741- Issue #4688: Add a heuristic so that tuples and dicts containing only
3742 untrackable objects are not tracked by the garbage collector. This can
3743 reduce the size of collections and therefore the garbage collection overhead
3744 on long-running programs, depending on their particular use of datatypes.
3745
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00003746- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

3758 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
3759 and sizeof(Py_UNICODE) == 2.
3760
Eric Smith8ec90442009-03-14 12:29:34 +00003761- Issue #5237: Allow auto-numbered fields in str.format(). For

3763
Antoine Pitrou652e7072009-03-13 19:25:20 +00003764- Issue #5392: when a very low recursion limit was set, the interpreter would
3765 abort with a fatal error after the recursion limit was hit twice.
3766
Matthias Klose042f1332009-04-04 14:32:42 +00003767- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

3813
Lars Gustäbel42e00912009-03-22 20:34:29 +00003814- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
3815 forever on incomplete input. That caused tarfile.open() to hang when used
3816 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
3817 partial bzip2 compressed data.
3818
Mark Dickinson79f52032009-03-17 23:12:51 +00003819- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +00003836- Issue #5463: In struct module, remove deprecated overflow wrapping
3837 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00003838 struct.error instead of returning b'\xff\xff\xff\xff'. The
3839 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
3840 have been removed from the struct module.

3887 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3888 evaluation loop is compiled with a new dispatch mechanism which gives
3889 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00003902 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00003903
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003904- Issue #4935: The overflow checking code in the expandtabs() method common
3905 to str, bytes and bytearray could be optimized away by the compiler, letting
3906 the interpreter segfault instead of raising an error.
3907
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003908- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00003930 having been closed (for instance, a read() call could return some
3931 previously buffered data). Patch by Dmitry Vasiliev.
3932
Antoine Pitrou05608432009-01-09 18:53:14 +00003933- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3934 flag to work properly. Furthermore, when specifying -u, the text stdout
3935 and stderr streams have line-by-line buffering enabled (the default being
3936 to buffer arbitrary chunks of data).
3937
Raymond Hettinger35631532009-01-09 03:58:09 +00003938- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3939 instead of ints (reducing its size from 4 to 8 times thereby reducing
3940 Python's overall memory).
3941
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003942- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3943 an existing .py counterpart, override the co_filename attributes of all
3944 code objects if the original filename is obsolete (which can happen if the
3945 file has been renamed, moved, or if it is accessed through different paths).
3946 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3947
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003948- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3949 one byte. Also fixes the meaning of len() so that it returns the number of
3950 items, rather than the size in bytes.
3951
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003952- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3953
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003954- Issue #4747: When the terminal does not use utf-8, executing a script with

3961 did not get collected.
3962
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003963- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types

4339
Antoine Pitrou08838b62009-01-21 00:55:13 +00004340- Issue #5008: When a file is opened in append mode with the new IO library,
4341 do an explicit seek to the end of file (so that e.g. tell() returns the
4342 file size rather than 0). This is consistent with the behaviour of the

4373 appropriately when it is being used via socket.makefile() objects
4374 rather than delaying the close by waiting for garbage collection to do it.
4375
Raymond Hettingerb8baf632009-01-14 02:20:07 +00004376- Issue #1696199: Add collections.Counter() for rapid and convenient
