Georg Brandlabc38772009-04-12 15:51:51 +000015- The string.maketrans() function is deprecated; there is a new static method
16 maketrans() on the bytes and bytearray classes. This removes confusion about
17 the types string.maketrans() is supposed to work with, and mirrors the
18 methods available on the str class.

48 integers.
Benjamin Petersond1735892009-03-07 18:46:21 +000049
Benjamin Peterson8f76b492009-04-03 22:22:42 +000050- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
51
Benjamin Peterson7fe98532009-04-02 00:33:55 +000052- Issue #5499: The 'c' code for argument parsing functions now only accepts a
53 byte, and the 'C' code only accepts a unicode character.
54
Georg Brandl406b3d82009-04-11 21:24:37 +000055- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
56 when hitting the recursion limit under certain circumstances.
57
Brett Cannon0759dd62009-04-01 18:13:07 +000058- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
59
Georg Brandlab6f2f62009-03-31 04:16:10 +000060- Fix a segfault when running test_exceptions with coverage, caused by
61 insufficient checks in accessors of Exception.__context__.
62
Guido van Rossum0ad59d42009-03-30 22:01:35 +000063- Issue #5604: non-ASCII characters in module name passed to
64 imp.find_module() were converted to UTF-8 while the path is
65 converted to the default filesystem encoding, causing nonsense.
66
Benjamin Peterson09832742009-03-26 17:15:46 +000067- Issue #5126: str.isprintable() returned False for space characters.
68
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +000069- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
70 the end sys.path, for compatibility with the system install of Python.
71
Antoine Pitrou3a652b12009-03-23 18:52:06 +000072- Issue #4688: Add a heuristic so that tuples and dicts containing only
73 untrackable objects are not tracked by the garbage collector. This can
74 reduce the size of collections and therefore the garbage collection overhead
75 on long-running programs, depending on their particular use of datatypes.
76
Mark Dickinson17e4fdd2009-03-23 18:44:57 +000077- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

82 2**15 for the internal representation of integers, for performance
83 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
84 --enable-big-digits option to configure, which overrides the
85 default. Add sys.int_info structseq to provide information about
86 the internal format.
87
Mark Dickinson081dfee2009-03-18 14:47:41 +000088- Issue #4474: PyUnicode_FromWideChar now converts characters outside
89 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
90 and sizeof(Py_UNICODE) == 2.
91
Eric Smith8ec90442009-03-14 12:29:34 +000092- Issue #5237: Allow auto-numbered fields in str.format(). For
93 example: '{} {}'.format(1, 2) == '1 2'.
94
Antoine Pitrou652e7072009-03-13 19:25:20 +000095- Issue #5392: when a very low recursion limit was set, the interpreter would
96 abort with a fatal error after the recursion limit was hit twice.
97
Matthias Klose042f1332009-04-04 14:32:42 +000098- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
99 short file names.

109 incrementalencoder and StreamWriter.
110
Georg Brandl33c28812009-04-01 23:07:29 +0000111- Issue #5656: Fix the coverage reporting when running the test suite with

129
Brett Cannon7f6b4f82009-03-30 21:30:26 +0000130- Issue #5236: Change time.strptime() to only take strings. Didn't work with
131 bytes already but the failure was non-obvious.
132
Jesse Noller7af4ef82009-03-30 16:47:15 +0000133- Issue #5177: Multiprocessing's SocketListener class now uses

136
Benjamin Peterson48e24782009-03-29 13:02:52 +0000137- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().

144
Lars Gustäbel42e00912009-03-22 20:34:29 +0000145- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
146 forever on incomplete input. That caused tarfile.open() to hang when used
147 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
148 partial bzip2 compressed data.
149
Mark Dickinson79f52032009-03-17 23:12:51 +0000150- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +0000156- The error detection code in FileIO.close() could fail to reflect the `errno`
157 value, and report it as -1 instead.
158
Antoine Pitroua28fcfd2009-03-13 23:42:55 +0000159- Issue #5016: FileIO.seekable() could return False if the file position

168 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000169 struct.error instead of returning b'\xff\xff\xff\xff'. The
170 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
171 have been removed from the struct module.

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

233 type to (void *).
234
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000235- Issue #4935: The overflow checking code in the expandtabs() method common
236 to str, bytes and bytearray could be optimized away by the compiler, letting
237 the interpreter segfault instead of raising an error.
238
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000239- Issue #3720: Fix a crash when an iterator modifies its class and removes its

251 common cases are optimized thanks to a dedicated fast path and a moderate
252 amount of loop unrolling.
253
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000254- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
255 collecting the oldest generation) so that allocating lots of objects without

258 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
259
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000260- Issue #4604: Some objects of the I/O library could still be used after

265 flag to work properly. Furthermore, when specifying -u, the text stdout
266 and stderr streams have line-by-line buffering enabled (the default being
267 to buffer arbitrary chunks of data).
268
Raymond Hettinger35631532009-01-09 03:58:09 +0000269- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
270 instead of ints (reducing its size from 4 to 8 times thereby reducing
271 Python's overall memory).
272
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000273- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
274 an existing .py counterpart, override the co_filename attributes of all
275 code objects if the original filename is obsolete (which can happen if the
276 file has been renamed, moved, or if it is accessed through different paths).
277 Patch by Ziga Seilnacht and Jean-Paul Calderone.
278
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000279- Issue #4580: Fix slicing of memoryviews when the item size is greater than
280 one byte. Also fixes the meaning of len() so that it returns the number of
281 items, rather than the size in bytes.
282
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000283- Issue #4075: Use OutputDebugStringW in Py_FatalError.

293
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000294- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
295 where the tp_hash and tp_dict slots are both NULL.
296
Georg Brandlccc47b62008-12-28 11:44:14 +0000297- Issue #4759: None is now allowed as the first argument of
298 bytearray.translate(). It was always allowed for bytes.translate().
299
Skip Montanaro80072cb2008-12-23 03:51:14 +0000300- Added test case to ensure attempts to read from a file opened for writing
301 fail.
302
