71 not installed. Instead, the zipfile.ZIP_STORED compression is used to create
72 the ZipFile. Patch by Natalia B. Bidart.
73
briancurtin94eceeb2011-03-14 15:35:35 -040074- Issue #11491: dbm.error is no longer raised when dbm.open is called with
75 the "n" as the flag argument and the file exists. The behavior matches
76 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +010077
Mark Dickinson37a79fb2011-03-12 11:12:52 +000078- Issue #11131: Fix sign of zero in decimal.Decimal plus and minus

96 32-bit Windows.
97
R. David Murray43b2f452011-02-11 03:13:19 +000098- email.header.Header was incorrectly encoding folding white space when
99 rfc2047-encoding header values with embedded newlines, leaving them
100 without folding whitespace. It now uses the continuation_ws, as it
101 does for continuation lines that it creates itself.
102
Georg Brandlf6c8fd62011-02-25 09:48:21 +0000103- Issue #10360: In WeakSet, do not raise TypeErrors when testing for

114 Patch by Stan Mihai.
115
Ned Deily7a8e21a2011-01-29 23:34:19 +0000116- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
117 preventing a confusing hung appearance on OS X with the windows
118 obscured.
119
Ned Deily26d55ed2011-01-29 19:22:26 +0000120- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save

122
Raymond Hettingerd62522a2011-01-27 00:12:08 +0000123- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3

134 length. Initial patch by Ross Lagerwall.
135
Antoine Pitrou710e9662011-01-19 15:26:37 +0000136- Issue #10898: Allow compiling the posix module when the C library defines
137 a symbol named FSTAT.
138
Antoine Pitroufb7bc3d2011-01-15 16:18:37 +0000139- Issue #10916: mmap should not segfault when a file is mapped using 0 as
140 length and a non-zero offset, and an attempt to read past the end of file
141 is made (IndexError is raised instead). Patch by Ross Lagerwall.
142
Raymond Hettingerd2b03e12011-01-12 23:52:40 +0000143- Issue #10899: No function type annotations in the standard library.

149 node twice.
150
R. David Murray389af002011-01-09 02:48:04 +0000151- Issue #5871: email.header.Header.encode now raises an error if any
152 continuation line in the formatted value has no leading white space
153 and looks like a header. Since Generator uses Header to format all
154 headers, this check is made for all headers in any serialized message
155 at serialization time. This provides protection against header
156 injection attacks.
157
Antoine Pitrouff173852011-01-06 18:29:05 +0000158- Issue #7858: Raise an error properly when os.utime() fails under Windows

171 file descriptors (0, 1, 2) are closed in the parent process. Initial
172 patch by Ross Lagerwall.
173
Éric Araujoe788ace2011-03-21 00:01:23 +0100174- Issue #10753 - Characters ';', '=' and ',' in the PATH_INFO environment
175 variable won't be quoted when the URI is constructed by the wsgiref.util's
Senthil Kumarane5f8e842010-12-29 06:29:58 +0000176 request_uri method. According to RFC 3986, these characters can be a part of
177 params in PATH component of URI and need not be quoted.
178

183
R. David Murray6cb252f2010-12-26 22:24:54 +0000184- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
185 it now prints the filename, line number, and traceback to stderr and skips
186 the rest of that individual file, instead of stopping processing entirely.
187
R. David Murray30f9c8c2010-12-21 21:57:54 +0000188- Issue #4871: The zipfile module now gives a more useful error message if

190

218 RFC3986. Anything before :// is considered a scheme and is followed by an
219 authority (or netloc) and by '/' led path, which is optional.
220
Antoine Pitrou976157f2010-12-03 19:21:49 +0000221- Issue #10478: Reentrant calls inside buffered IO objects (for example by

Victor Stinner15244f72010-10-19 01:22:07 +0000381- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
382 filenames encoded to the filesystem encoding with surrogateescape error
383 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
384
Benjamin Peterson0ad44fa2010-10-02 18:04:55 +0000385- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a

428 output with no type specifier failed to match the str output:
429
430 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
431 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
432
Antoine Pitroudedbbe62010-07-11 12:15:03 +0000433- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
434 compiler.
435
Ezio Melotti25bc0192010-07-03 05:18:50 +0000436- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
437 start byte and the continuation byte(s) are now considered invalid, instead
438 of the number of bytes specified by the start byte.
439 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
440 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
441 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
442 Previous versions returned a single u'\ufffd'.

Victor Stinnera27dcb72010-04-25 22:39:07 +0000910- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
911 and bytes strings for environment keys and values, and use
912 sys.getfilesystemencoding() instead of sys.getdefautltencoding()

Antoine Pitroue3123912010-04-25 22:26:08 +0000914- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
915 where the method could block indefinitely if called just before the

Antoine Pitrouc2203f92010-04-24 22:07:51 +0000919- Issue #8524: When creating an SSL socket, the timeout value of the
920 original socket wasn't retained (instead, a socket with a positive timeout
921 would be turned into a non-blocking SSL socket).
922
Antoine Pitrouec146182010-04-24 21:30:20 +0000923- Issue #5103: SSL handshake would ignore the socket timeout and block
924 indefinitely if the other end didn't respond.
925
926- The do_handshake() method of SSL objects now adjusts the blocking mode of
927 the SSL structure if necessary (as other methods already do).
928

930 a non-infinite timeout. Also make that method friendlier with applications
931 wanting to continue using the socket in clear-text mode, by disabling
932 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

2059Core and Builtins
2060-----------------
2061
Mark Dickinson865e01a2009-05-07 16:37:01 +00002062- Issue #5914: Add new C API function PyOS_string_to_double, and
2063 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2064
Eric Smith741191f2009-05-06 13:08:15 +00002065- Issue #3382: float.__format__, complex.__format__, and %-formatting
2066 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2067 affects nan -> NAN and inf -> INF.
2068
Mark Hammond5a607a32009-05-06 08:04:54 +00002069- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2070 in all operations, including splitdrive, split, etc. splitunc() now issues
2071 a PendingDeprecation warning.
2072
Eric Smith63376222009-05-05 14:04:18 +00002073- Issue #5920: For float.__format__, change the behavior with the
2074 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2075 to be like 'g' but with at least one decimal point and with a
2076 default precision of 12. Previously, the behavior the same but with
2077 a default precision of 6. This more closely matches str(), and
2078 reduces surprises when adding alignment flags to the empty
2079 presentation type. This also affects the new complex.__format__ in
2080 the same way.
2081
Martin v. Löwis011e8422009-05-05 04:43:17 +00002082- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2083
R. David Murrayb18500d2009-05-04 22:59:07 +00002084- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2085 shadowed by classtype's, even if it was None. property now
2086 inserts the __doc__ into the subclass instance __dict__.
2087
Antoine Pitrou244651a2009-05-04 18:56:13 +00002088- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2089 sequences. Patch by Nick Barnes and Victor Stinner.
2090
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002091- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002092
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002093- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2094 received a new method, detach(). detach() disconnects the underlying stream
2095 from the buffer or text IO and returns it.
2096
Mark Dickinson33841c32009-05-01 15:37:04 +00002097- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2098 floats with absolute value over 1e50. Also remove length
2099 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2100 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002101
Eric Smith741191f2009-05-06 13:08:15 +00002102- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002103 format(complex(1, 2./3), '.5') now produces a sensible result.
2104
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002105- Issue #5864: Fix empty format code formatting for floats so that it
2106 never gives more than the requested number of significant digits.
2107
Eric Smith6dc46f52009-04-27 20:39:49 +00002108- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2109 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2110
Eric Smithcc32a112009-04-26 21:35:14 +00002111- Issue #5835: Deprecate PyOS_ascii_formatd.
2112
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002113- Issue #4971: Fix titlecase for characters that are their own
2114 titlecase, but not their own uppercase.
2115
Benjamin Peterson193152c2009-04-25 01:08:45 +00002116- Issue #5283: Setting __class__ in __del__ caused a segfault.
2117
Mark Dickinsonad476da2009-04-23 19:14:16 +00002118- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2119 z involves nans, infs or negative zeros.
2120
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002121- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002122
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002123- Issue #1869 (and many duplicates): make round(x, n) correctly
2124 rounded for a float x, by using the decimal <-> binary conversions
2125 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2126 consistently agrees with format(x, '.2f').
2127
Benjamin Petersonae937c02009-04-18 20:54:08 +00002128- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2129 some builtin types.
2130
Eric Smith0923d1d2009-04-16 20:16:10 +00002131- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2132
Eric Smith35e84722009-04-16 20:21:28 +00002133- Issue #5515: str.format() type 'n' combined with commas and leading
2134 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002135
2136- Implement PEP 378, Format Specifier for Thousands Separator, for
2137 floats.
2138
Mark Dickinson3370cce2009-04-17 22:40:53 +00002139- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002140 1e11, not 1e12. This avoids printing 13 significant digits in
2141 situations where only 12 of them are correct. Example problem
2142 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2143 long time.)
2144
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002145- Issue #1580: On most platforms, use a 'short' float repr: for a
2146 finite float x, repr(x) now outputs a string based on the shortest
2147 sequence of decimal digits that rounds to x. Previous behaviour was
2148 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002149 Another minor difference is that the new repr switches to
2150 exponential notation at 1e16 instead of the previous 1e17; this
2151 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002152
2153 There's a new sys attribute sys.float_repr_style, which takes
2154 the value 'short' to indicate that we're using short float repr,
2155 and 'legacy' if the short float repr isn't available for one
2156 reason or another.
2157
2158 The float repr change involves incorporating David Gay's 'perfect
2159 rounding' code into the Python core (it's in Python/dtoa.c). As a
2160 secondary consequence, all string-to-float and float-to-string
2161 conversions (including all float formatting operations) will be
2162 correctly rounded on these platforms.
2163
Georg Brandl442d3b32010-08-01 22:33:12 +00002164 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002165 this change does not apply.
2166
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002167- Issue #5759: float() didn't call __float__ on str subclasses.
2168
Georg Brandlabc38772009-04-12 15:51:51 +00002169- The string.maketrans() function is deprecated; there is a new static method
2170 maketrans() on the bytes and bytearray classes. This removes confusion about
2171 the types string.maketrans() is supposed to work with, and mirrors the
2172 methods available on the str class.
2173
R. David Murraydc6da8a2009-04-09 22:16:43 +00002174- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2175 its clarity and its speed.
2176
Matthias Klose091c7b12009-04-07 13:24:27 +00002177- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2178 to avoid compiler warnings.
2179
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002180- Issue #3739: The unicode-internal encoder now reports the number of characters
2181 consumed like any other encoder (instead of the number of bytes).

Georg Brandl406b3d82009-04-11 21:24:37 +00002321- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2322 when hitting the recursion limit under certain circumstances.
2323
Brett Cannon0759dd62009-04-01 18:13:07 +00002324- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2325
Georg Brandlab6f2f62009-03-31 04:16:10 +00002326- Fix a segfault when running test_exceptions with coverage, caused by
2327 insufficient checks in accessors of Exception.__context__.
2328
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002329- Issue #5604: non-ASCII characters in module name passed to
2330 imp.find_module() were converted to UTF-8 while the path is
2331 converted to the default filesystem encoding, causing nonsense.
2332
Benjamin Peterson09832742009-03-26 17:15:46 +00002333- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002335- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2336 the end sys.path, for compatibility with the system install of Python.
2337
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002338- Issue #4688: Add a heuristic so that tuples and dicts containing only
2339 untrackable objects are not tracked by the garbage collector. This can
2340 reduce the size of collections and therefore the garbage collection overhead
2341 on long-running programs, depending on their particular use of datatypes.
2342
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002343- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2344 improve its performance. Long divisions and remainder operations
2345 are now between 50% and 150% faster.
2346
Mark Dickinsonbd792642009-03-18 20:06:12 +00002347- Issue #4258: Make it possible to use base 2**30 instead of base
2348 2**15 for the internal representation of integers, for performance
2349 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2350 --enable-big-digits option to configure, which overrides the
2351 default. Add sys.int_info structseq to provide information about
2352 the internal format.
2353
Mark Dickinson081dfee2009-03-18 14:47:41 +00002354- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2355 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2356 and sizeof(Py_UNICODE) == 2.
2357
Eric Smith8ec90442009-03-14 12:29:34 +00002358- Issue #5237: Allow auto-numbered fields in str.format(). For
2359 example: '{} {}'.format(1, 2) == '1 2'.
2360
Antoine Pitrou652e7072009-03-13 19:25:20 +00002361- Issue #5392: when a very low recursion limit was set, the interpreter would
2362 abort with a fatal error after the recursion limit was hit twice.
2363
Matthias Klose042f1332009-04-04 14:32:42 +00002364- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2410
Lars Gustäbel42e00912009-03-22 20:34:29 +00002411- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2412 forever on incomplete input. That caused tarfile.open() to hang when used
2413 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002435 struct.error instead of returning b'\xff\xff\xff\xff'. The
2436 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002461- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2462 rotating the object pointer by 4 bits to the right.
2463
Mark Dickinson87ec0852009-02-09 17:15:59 +00002464- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2465 it now forces its argument to double before testing for infinity.
2466
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002467- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2468 returns a non-number type.
2469
Benjamin Peterson87618552009-02-08 15:00:52 +00002470- Issue #5182: Removed memoryview.__str__.

2475 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002476
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002477- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002478 were suppressing all exceptions. These include list() and bytearray().
2479
Mark Dickinson1124e712009-01-28 21:25:58 +00002480- Issue #4707: round(x, n) now returns an integer if x is an integer.
2481 Previously it returned a float.
2482
Antoine Pitroub52ec782009-01-25 16:34:23 +00002483- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2484 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2485 evaluation loop is compiled with a new dispatch mechanism which gives
2486 speedups of up to 20%, depending on the system, on various benchmarks.
2487
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002488- Issue #4874: Most builtin decoders now reject unicode input.

2494
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002495- Issue #4838: When a module is deallocated, free the memory backing the
2496 optional module state data.
2497
Mark Dickinson8055afd2009-01-17 10:04:45 +00002498- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2499 type to (void *).
2500
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002501- Issue #4935: The overflow checking code in the expandtabs() method common
2502 to str, bytes and bytearray could be optimized away by the compiler, letting
2503 the interpreter segfault instead of raising an error.
2504
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002505- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2506 __next__ method.
2507
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002508- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2515
Antoine Pitrouab868312009-01-10 15:40:25 +00002516- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2517 common cases are optimized thanks to a dedicated fast path and a moderate
2518 amount of loop unrolling.
2519
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002520- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2521 collecting the oldest generation) so that allocating lots of objects without
2522 destroying them does not show quadratic performance. Based on a proposal by
2523 Martin von Löwis at
2524 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2525
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002526- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002527 having been closed (for instance, a read() call could return some
2528 previously buffered data). Patch by Dmitry Vasiliev.
2529
Antoine Pitrou05608432009-01-09 18:53:14 +00002530- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2531 flag to work properly. Furthermore, when specifying -u, the text stdout
2532 and stderr streams have line-by-line buffering enabled (the default being
2533 to buffer arbitrary chunks of data).
2534
Raymond Hettinger35631532009-01-09 03:58:09 +00002535- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2536 instead of ints (reducing its size from 4 to 8 times thereby reducing
2537 Python's overall memory).
2538
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002539- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2540 an existing .py counterpart, override the co_filename attributes of all
2541 code objects if the original filename is obsolete (which can happen if the
2542 file has been renamed, moved, or if it is accessed through different paths).
2543 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2544
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002545- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2546 one byte. Also fixes the meaning of len() so that it returns the number of
2547 items, rather than the size in bytes.
2548
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002549- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2550
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002551- Issue #4747: When the terminal does not use utf-8, executing a script with
2552 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2553
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002554- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002555 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002556
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002557- Issue #3680: Reference cycles created through a dict, set or deque iterator
2558 did not get collected.
2559
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002560- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2561 where the tp_hash and tp_dict slots are both NULL.
2562
Georg Brandlccc47b62008-12-28 11:44:14 +00002563- Issue #4759: None is now allowed as the first argument of
2564 bytearray.translate(). It was always allowed for bytes.translate().
2565
Skip Montanaro80072cb2008-12-23 03:51:14 +00002566- Added test case to ensure attempts to read from a file opened for writing
2567 fail.
2568
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002569- Issue #3106: Speedup some comparisons (str/str and int/int).

2572 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2573
Antoine Pitrou621601a2008-12-17 23:18:19 +00002574- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2575 print elapsed times, not only when some objects are uncollectable /
2576 unreachable. Original patch by Neil Schemenauer.
2577
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002578- Issue #3439: Add a bit_length method to int.
2579
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002580- Issue #2173: When getting device encoding, check that return value of
2581 nl_langinfo is not the empty string. This was causing silent build
2582 failures on OS X.
2583
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002584- Issue #4597: Fixed several opcodes that weren't always propagating
2585 exceptions.
2586
2587- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002588 context manager returns a value that cannot be converted to a bool.
2589
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002590- Issue #4445: Replace "sizeof(PyBytesObject)" with
2591 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2592 bytes instances. On a typical machine this saves 3 bytes of memory
2593 (on average) per allocation of a bytes instance.
2594
Christian Heimesa872de52008-12-05 08:26:55 +00002595- Issue #4533: File read operation was dreadfully slow due to a slowly
2596 growing read buffer. Fixed by using the same growth rate algorithm as
2597 Python 2.x.
2598
Antoine Pitrou5504e892008-12-06 21:27:53 +00002599- Issue #4509: Various issues surrounding resize of bytearray objects to
2600 which there are buffer exports (e.g. memoryview instances).
2601
Georg Brandlf9734072008-12-07 15:30:06 +00002602- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
