36

Antoine Pitrou877766d2011-03-19 17:00:37 +010050- Issue #11459: A ``bufsize`` value of 0 in subprocess.Popen() really creates
51 unbuffered pipes, such that select() works properly on them.
52
Antoine Pitrou5e981412011-03-17 22:38:37 +010053- Issue #5421: Fix misleading error message when one of socket.sendto()'s

55
R David Murrayde912762011-03-16 18:26:23 -040056- Issue #11401: fix handling of headers with no value; this fixes a regression

68 not installed. Instead, the zipfile.ZIP_STORED compression is used to create
69 the ZipFile. Patch by Natalia B. Bidart.
70
briancurtin94eceeb2011-03-14 15:35:35 -040071- Issue #11491: dbm.error is no longer raised when dbm.open is called with
72 the "n" as the flag argument and the file exists. The behavior matches
73 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +010074
Mark Dickinson37a79fb2011-03-12 11:12:52 +000075- Issue #11131: Fix sign of zero in decimal.Decimal plus and minus

93 32-bit Windows.
94
R. David Murray43b2f452011-02-11 03:13:19 +000095- email.header.Header was incorrectly encoding folding white space when
96 rfc2047-encoding header values with embedded newlines, leaving them
97 without folding whitespace. It now uses the continuation_ws, as it
98 does for continuation lines that it creates itself.
99
Georg Brandlf6c8fd62011-02-25 09:48:21 +0000100- Issue #10360: In WeakSet, do not raise TypeErrors when testing for

111 Patch by Stan Mihai.
112
Ned Deily7a8e21a2011-01-29 23:34:19 +0000113- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
114 preventing a confusing hung appearance on OS X with the windows
115 obscured.
116
Ned Deily26d55ed2011-01-29 19:22:26 +0000117- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save

119
Raymond Hettingerd62522a2011-01-27 00:12:08 +0000120- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3

Antoine Pitrou6107a4e2011-01-20 21:11:13 +0000130- Issue #10955: Fix a potential crash when trying to mmap() a file past its
131 length. Initial patch by Ross Lagerwall.
132
Antoine Pitrou710e9662011-01-19 15:26:37 +0000133- Issue #10898: Allow compiling the posix module when the C library defines
134 a symbol named FSTAT.
135
Antoine Pitroufb7bc3d2011-01-15 16:18:37 +0000136- Issue #10916: mmap should not segfault when a file is mapped using 0 as
137 length and a non-zero offset, and an attempt to read past the end of file
138 is made (IndexError is raised instead). Patch by Ross Lagerwall.
139
Raymond Hettingerd2b03e12011-01-12 23:52:40 +0000140- Issue #10899: No function type annotations in the standard library.

146 node twice.
147
R. David Murray389af002011-01-09 02:48:04 +0000148- Issue #5871: email.header.Header.encode now raises an error if any
149 continuation line in the formatted value has no leading white space
150 and looks like a header. Since Generator uses Header to format all
151 headers, this check is made for all headers in any serialized message
152 at serialization time. This provides protection against header
153 injection attacks.
154
Antoine Pitrouff173852011-01-06 18:29:05 +0000155- Issue #7858: Raise an error properly when os.utime() fails under Windows

165 to avoid a potential rare deadlock or crash on some platforms.
166

168 file descriptors (0, 1, 2) are closed in the parent process. Initial
169 patch by Ross Lagerwall.
170
Éric Araujoe788ace2011-03-21 00:01:23 +0100171- Issue #10753 - Characters ';', '=' and ',' in the PATH_INFO environment
172 variable won't be quoted when the URI is constructed by the wsgiref.util's
Senthil Kumarane5f8e842010-12-29 06:29:58 +0000173 request_uri method. According to RFC 3986, these characters can be a part of
174 params in PATH component of URI and need not be quoted.
175

Éric Araujoe788ace2011-03-21 00:01:23 +0100178- Issue #9824: SimpleCookie now encodes , and ; in values to cater to how
R. David Murraydaa7ba02010-12-28 18:56:33 +0000179 browsers actually parse cookies.
180
R. David Murray6cb252f2010-12-26 22:24:54 +0000181- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
182 it now prints the filename, line number, and traceback to stderr and skips
183 the rest of that individual file, instead of stopping processing entirely.
184
R. David Murray30f9c8c2010-12-21 21:57:54 +0000185- Issue #4871: The zipfile module now gives a more useful error message if

187

197
Senthil Kumaran3396e862010-12-17 04:54:43 +0000198- Issue #9721: Fix the behavior of urljoin when the relative url starts with a

215 RFC3986. Anything before :// is considered a scheme and is followed by an
216 authority (or netloc) and by '/' led path, which is optional.
217
Antoine Pitrou976157f2010-12-03 19:21:49 +0000218- Issue #10478: Reentrant calls inside buffered IO objects (for example by

Victor Stinner15244f72010-10-19 01:22:07 +0000378- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
379 filenames encoded to the filesystem encoding with surrogateescape error
380 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
381
Benjamin Peterson0ad44fa2010-10-02 18:04:55 +0000382- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a

393 a single ``\UXXXXXXXX``, regardless of whether the character is printable

396
Antoine Pitrou3c6261a2010-09-08 12:48:12 +0000397- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

425 output with no type specifier failed to match the str output:
426
427 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
428 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
429
Antoine Pitroudedbbe62010-07-11 12:15:03 +0000430- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
431 compiler.
432
Ezio Melotti25bc0192010-07-03 05:18:50 +0000433- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
434 start byte and the continuation byte(s) are now considered invalid, instead
435 of the number of bytes specified by the start byte.
436 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
437 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
438 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
439 Previous versions returned a single u'\ufffd'.

Antoine Pitroue3123912010-04-25 22:26:08 +0000911- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
912 where the method could block indefinitely if called just before the
913 event loop started running. This also fixes the occasional freezes
914 witnessed in test_httpservers.
915
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000916- Issue #8524: When creating an SSL socket, the timeout value of the
917 original socket wasn't retained (instead, a socket with a positive timeout
918 would be turned into a non-blocking SSL socket).
919
Antoine Pitrouec146182010-04-24 21:30:20 +0000920- Issue #5103: SSL handshake would ignore the socket timeout and block
921 indefinitely if the other end didn't respond.
922
923- The do_handshake() method of SSL objects now adjusts the blocking mode of
924 the SSL structure if necessary (as other methods already do).
925
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000926- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
927 a non-infinite timeout. Also make that method friendlier with applications
928 wanting to continue using the socket in clear-text mode, by disabling
929 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002055
2056Core and Builtins
2057-----------------
2058
Mark Dickinson865e01a2009-05-07 16:37:01 +00002059- Issue #5914: Add new C API function PyOS_string_to_double, and
2060 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2061
Eric Smith741191f2009-05-06 13:08:15 +00002062- Issue #3382: float.__format__, complex.__format__, and %-formatting
2063 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2064 affects nan -> NAN and inf -> INF.
2065
Mark Hammond5a607a32009-05-06 08:04:54 +00002066- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2067 in all operations, including splitdrive, split, etc. splitunc() now issues
2068 a PendingDeprecation warning.
2069
Eric Smith63376222009-05-05 14:04:18 +00002070- Issue #5920: For float.__format__, change the behavior with the
2071 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2072 to be like 'g' but with at least one decimal point and with a
2073 default precision of 12. Previously, the behavior the same but with
2074 a default precision of 6. This more closely matches str(), and
2075 reduces surprises when adding alignment flags to the empty
2076 presentation type. This also affects the new complex.__format__ in
2077 the same way.
2078
Martin v. Löwis011e8422009-05-05 04:43:17 +00002079- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2080
R. David Murrayb18500d2009-05-04 22:59:07 +00002081- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2082 shadowed by classtype's, even if it was None. property now
2083 inserts the __doc__ into the subclass instance __dict__.
2084
Antoine Pitrou244651a2009-05-04 18:56:13 +00002085- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2086 sequences. Patch by Nick Barnes and Victor Stinner.
2087
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002088- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002089
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002090- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2091 received a new method, detach(). detach() disconnects the underlying stream
2092 from the buffer or text IO and returns it.
2093
Mark Dickinson33841c32009-05-01 15:37:04 +00002094- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2095 floats with absolute value over 1e50. Also remove length
2096 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2097 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002098
Eric Smith741191f2009-05-06 13:08:15 +00002099- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002100 format(complex(1, 2./3), '.5') now produces a sensible result.
2101
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002102- Issue #5864: Fix empty format code formatting for floats so that it
2103 never gives more than the requested number of significant digits.
2104
Eric Smith6dc46f52009-04-27 20:39:49 +00002105- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2106 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2107
Eric Smithcc32a112009-04-26 21:35:14 +00002108- Issue #5835: Deprecate PyOS_ascii_formatd.
2109
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002110- Issue #4971: Fix titlecase for characters that are their own
2111 titlecase, but not their own uppercase.
2112
Benjamin Peterson193152c2009-04-25 01:08:45 +00002113- Issue #5283: Setting __class__ in __del__ caused a segfault.
2114
Mark Dickinsonad476da2009-04-23 19:14:16 +00002115- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2116 z involves nans, infs or negative zeros.
2117
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002118- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002119
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002120- Issue #1869 (and many duplicates): make round(x, n) correctly
2121 rounded for a float x, by using the decimal <-> binary conversions
2122 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2123 consistently agrees with format(x, '.2f').
2124
Benjamin Petersonae937c02009-04-18 20:54:08 +00002125- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2126 some builtin types.
2127
Eric Smith0923d1d2009-04-16 20:16:10 +00002128- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2129
Eric Smith35e84722009-04-16 20:21:28 +00002130- Issue #5515: str.format() type 'n' combined with commas and leading
2131 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002132
2133- Implement PEP 378, Format Specifier for Thousands Separator, for
2134 floats.
2135
Mark Dickinson3370cce2009-04-17 22:40:53 +00002136- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002137 1e11, not 1e12. This avoids printing 13 significant digits in
2138 situations where only 12 of them are correct. Example problem
2139 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2140 long time.)
2141
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002142- Issue #1580: On most platforms, use a 'short' float repr: for a
2143 finite float x, repr(x) now outputs a string based on the shortest
2144 sequence of decimal digits that rounds to x. Previous behaviour was
2145 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002146 Another minor difference is that the new repr switches to
2147 exponential notation at 1e16 instead of the previous 1e17; this
2148 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002149
2150 There's a new sys attribute sys.float_repr_style, which takes
2151 the value 'short' to indicate that we're using short float repr,
2152 and 'legacy' if the short float repr isn't available for one
2153 reason or another.
2154
2155 The float repr change involves incorporating David Gay's 'perfect
2156 rounding' code into the Python core (it's in Python/dtoa.c). As a
2157 secondary consequence, all string-to-float and float-to-string
2158 conversions (including all float formatting operations) will be
2159 correctly rounded on these platforms.
2160
Georg Brandl442d3b32010-08-01 22:33:12 +00002161 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002162 this change does not apply.
2163
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002164- Issue #5759: float() didn't call __float__ on str subclasses.
2165
Georg Brandlabc38772009-04-12 15:51:51 +00002166- The string.maketrans() function is deprecated; there is a new static method
2167 maketrans() on the bytes and bytearray classes. This removes confusion about
2168 the types string.maketrans() is supposed to work with, and mirrors the
2169 methods available on the str class.
2170
R. David Murraydc6da8a2009-04-09 22:16:43 +00002171- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2172 its clarity and its speed.
2173
Matthias Klose091c7b12009-04-07 13:24:27 +00002174- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2175 to avoid compiler warnings.
2176
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002177- Issue #3739: The unicode-internal encoder now reports the number of characters
2178 consumed like any other encoder (instead of the number of bytes).

Georg Brandlab6f2f62009-03-31 04:16:10 +00002323- Fix a segfault when running test_exceptions with coverage, caused by
2324 insufficient checks in accessors of Exception.__context__.
2325
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002326- Issue #5604: non-ASCII characters in module name passed to
2327 imp.find_module() were converted to UTF-8 while the path is
2328 converted to the default filesystem encoding, causing nonsense.
2329
Benjamin Peterson09832742009-03-26 17:15:46 +00002330- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002332- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2333 the end sys.path, for compatibility with the system install of Python.
2334
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002335- Issue #4688: Add a heuristic so that tuples and dicts containing only
2336 untrackable objects are not tracked by the garbage collector. This can
2337 reduce the size of collections and therefore the garbage collection overhead
2338 on long-running programs, depending on their particular use of datatypes.
2339
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002340- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2341 improve its performance. Long divisions and remainder operations
2342 are now between 50% and 150% faster.
2343
Mark Dickinsonbd792642009-03-18 20:06:12 +00002344- Issue #4258: Make it possible to use base 2**30 instead of base
2345 2**15 for the internal representation of integers, for performance
2346 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2347 --enable-big-digits option to configure, which overrides the
2348 default. Add sys.int_info structseq to provide information about
2349 the internal format.
2350
Mark Dickinson081dfee2009-03-18 14:47:41 +00002351- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2352 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2353 and sizeof(Py_UNICODE) == 2.
2354
Eric Smith8ec90442009-03-14 12:29:34 +00002355- Issue #5237: Allow auto-numbered fields in str.format(). For

2357
Antoine Pitrou652e7072009-03-13 19:25:20 +00002358- Issue #5392: when a very low recursion limit was set, the interpreter would
2359 abort with a fatal error after the recursion limit was hit twice.
2360
Matthias Klose042f1332009-04-04 14:32:42 +00002361- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2407
Lars Gustäbel42e00912009-03-22 20:34:29 +00002408- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2409 forever on incomplete input. That caused tarfile.open() to hang when used
2410 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinson87ec0852009-02-09 17:15:59 +00002461- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2462 it now forces its argument to double before testing for infinity.
2463
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002464- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2465 returns a non-number type.
2466
Benjamin Peterson87618552009-02-08 15:00:52 +00002467- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002473
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002474- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002475 were suppressing all exceptions. These include list() and bytearray().
2476
Mark Dickinson1124e712009-01-28 21:25:58 +00002477- Issue #4707: round(x, n) now returns an integer if x is an integer.
2478 Previously it returned a float.
2479
Antoine Pitroub52ec782009-01-25 16:34:23 +00002480- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2481 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2482 evaluation loop is compiled with a new dispatch mechanism which gives
2483 speedups of up to 20%, depending on the system, on various benchmarks.
2484
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002485- Issue #4874: Most builtin decoders now reject unicode input.

2491
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002492- Issue #4838: When a module is deallocated, free the memory backing the
2493 optional module state data.
2494
Mark Dickinson8055afd2009-01-17 10:04:45 +00002495- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2496 type to (void *).
2497
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002498- Issue #4935: The overflow checking code in the expandtabs() method common
2499 to str, bytes and bytearray could be optimized away by the compiler, letting
2500 the interpreter segfault instead of raising an error.
2501
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002502- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2503 __next__ method.
2504
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002505- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2512
Antoine Pitrouab868312009-01-10 15:40:25 +00002513- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2514 common cases are optimized thanks to a dedicated fast path and a moderate
2515 amount of loop unrolling.
2516
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002517- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2518 collecting the oldest generation) so that allocating lots of objects without
2519 destroying them does not show quadratic performance. Based on a proposal by
2520 Martin von Löwis at
2521 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2522
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002523- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002524 having been closed (for instance, a read() call could return some
2525 previously buffered data). Patch by Dmitry Vasiliev.
2526
Antoine Pitrou05608432009-01-09 18:53:14 +00002527- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2528 flag to work properly. Furthermore, when specifying -u, the text stdout
2529 and stderr streams have line-by-line buffering enabled (the default being
2530 to buffer arbitrary chunks of data).
2531
Raymond Hettinger35631532009-01-09 03:58:09 +00002532- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2533 instead of ints (reducing its size from 4 to 8 times thereby reducing
2534 Python's overall memory).
2535
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002536- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2537 an existing .py counterpart, override the co_filename attributes of all
2538 code objects if the original filename is obsolete (which can happen if the
2539 file has been renamed, moved, or if it is accessed through different paths).
2540 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2541
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002542- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2543 one byte. Also fixes the meaning of len() so that it returns the number of
2544 items, rather than the size in bytes.
2545
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002546- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2547
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002548- Issue #4747: When the terminal does not use utf-8, executing a script with
2549 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2550
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002551- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002552 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002553
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002554- Issue #3680: Reference cycles created through a dict, set or deque iterator
2555 did not get collected.
2556
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002557- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2558 where the tp_hash and tp_dict slots are both NULL.
2559
Georg Brandlccc47b62008-12-28 11:44:14 +00002560- Issue #4759: None is now allowed as the first argument of
2561 bytearray.translate(). It was always allowed for bytes.translate().
2562
Skip Montanaro80072cb2008-12-23 03:51:14 +00002563- Added test case to ensure attempts to read from a file opened for writing
2564 fail.
2565
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002566- Issue #3106: Speedup some comparisons (str/str and int/int).

2570
Antoine Pitrou621601a2008-12-17 23:18:19 +00002571- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2572 print elapsed times, not only when some objects are uncollectable /
2573 unreachable. Original patch by Neil Schemenauer.
2574
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002575- Issue #3439: Add a bit_length method to int.
2576
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002577- Issue #2173: When getting device encoding, check that return value of
2578 nl_langinfo is not the empty string. This was causing silent build
2579 failures on OS X.
2580
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002581- Issue #4597: Fixed several opcodes that weren't always propagating
2582 exceptions.
2583
2584- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002585 context manager returns a value that cannot be converted to a bool.
2586
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002587- Issue #4445: Replace "sizeof(PyBytesObject)" with
2588 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2589 bytes instances. On a typical machine this saves 3 bytes of memory
2590 (on average) per allocation of a bytes instance.
2591
Christian Heimesa872de52008-12-05 08:26:55 +00002592- Issue #4533: File read operation was dreadfully slow due to a slowly
2593 growing read buffer. Fixed by using the same growth rate algorithm as
2594 Python 2.x.
2595
Antoine Pitrou5504e892008-12-06 21:27:53 +00002596- Issue #4509: Various issues surrounding resize of bytearray objects to
2597 which there are buffer exports (e.g. memoryview instances).
2598
Georg Brandlf9734072008-12-07 15:30:06 +00002599- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2600 method on file objects with closefd=False. The file descriptor is still
2601 kept open but the file object behaves like a closed file. The ``FileIO``
2602 object also got a new readonly attribute ``closefd``.
