210 encoding. This is the preferred encoding of PEP 3333 and the base encoding
211 of HTTP 1.1.
212
Armin Ronacher59531282011-01-22 13:44:22 +0000213- To match the behaviour of HTTP server, the HTTP client library now also
214 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Georg Brandl255abdd2011-01-16 14:17:26 +0000307 continuation line in the formatted value has no leading white space and looks
308 like a header. Since Generator uses Header to format all headers, this check
309 is made for all headers in any serialized message at serialization time. This
310 provides protection against header injection attacks.

R. David Murray6f0022d2011-01-07 21:57:25 +0000322- email.header.Header was incorrectly encoding folding white space when

324 folding whitespace. It now uses the continuation_ws, as it does for
325 continuation lines that it creates itself.

328 time.asctime(), time.ctime() and time.strftime() functions will now format
329 any year when ``time.accept2dyear`` is False and will accept years >= 1000
330 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
331 supported by the OS. With Visual Studio or on Solaris, the year is limited to
332 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +0000956- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
957 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +0000958 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +0000959 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +0000960 encoding and to encode command line arguments on this OS.

965
Benjamin Peterson230b2062010-10-16 03:45:45 +0000966- Issue #9997: Don't let the name "top" have special significance in scope
967 resolution.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001073 incorrectly validated some non-compliant applications as WSGI compliant; if
1074 your app validates with Python <3.2b1+, but not on this version, it is likely
1075 the case that your app was not compliant.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001339- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

1341 Py_Initialize().
1342
Georg Brandl27a28582010-10-10 09:49:21 +00001343- All SyntaxErrors now have a column offset and therefore a caret when the error

Brett Cannonbc2eff32010-09-19 21:39:02 +00001346- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

Nick Coghlan37ee8502010-12-03 14:26:13 +00001349- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00001352- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1353 with a non-empty format string. This is an effort to future-proof user
1354 code. If a derived class does not currently implement __format__ but later
1355 adds its own __format__, it would most likely break user code that had
1356 supplied a format string. This will be changed to a DeprecationWaring in
1357 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00001359- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1360 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1361 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 +00001363- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1364 functions from the libc caused the methods .upper() and lower() to become
1365 locale aware and created subtly wrong results.
1366
Georg Brandl27a28582010-10-10 09:49:21 +00001367- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001370- Issue #4617: Previously it was illegal to delete a name from the local
1371 namespace if it occurs as a free variable in a nested block. This limitation
1372 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1373
Georg Brandl27a28582010-10-10 09:49:21 +00001374- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1375 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1376 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1377 single character on UCS-2 builds.

Antoine Pitrou079ce542010-09-08 12:37:10 +00001383- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001412- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001413 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001414 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001415 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00001440 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001522- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001523 it possible for the user to create self-referencing ordered dictionaries which
1524 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001525 approach of using weakref proxies so that reference cycles never get created
1526 in the first place.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001551- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1552 still return the id of the parent process after it has exited. This process
1553 id may even have been reused by another unrelated process.

Georg Brandl27a28582010-10-10 09:49:21 +00001569 * Update the seed() method to use all of the bits in a string instead of just
1570 the hash value. This makes better use of the seed value and assures the
1571 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00001573 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1574 sample(), randrange(), and randint(). Formerly, it used int(n*random())

1728 return characters from the full Unicode range, even on narrow unicode builds
1729 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

1731 large code points, and repr() may consider more characters as printable.

1769 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001770
1771 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

2103
Victor Stinner8182b712010-07-28 00:40:58 +00002104- Issue #8991: convertbuffer() rejects discontigious buffers.
2105
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00002106- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
2107 compiler.

2110
Ezio Melotti57221d02010-07-01 07:32:02 +00002111- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002112 start byte and the continuation byte(s) are now considered invalid, instead of
2113 the number of bytes specified by the start byte. E.g.:
2114 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2115 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2116 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2117 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00002118
Georg Brandl62069d32010-07-31 08:56:11 +00002119- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2120 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002121
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002122- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00002131- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2132 dealing with unary minus applied to a constant. The removed code was mutating
2133 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002134
Victor Stinner554f3f02010-06-16 23:33:54 +00002135- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002136 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002137 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002138 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002139
Victor Stinner25e8ec42010-06-25 00:02:38 +00002140- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2141 "w*" format instead. Add tests for "w*" format.
2142
Victor Stinner06e49dd2010-06-13 18:21:50 +00002143- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002144 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002145 string formats.
2146
Georg Brandl62069d32010-07-31 08:56:11 +00002147- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002148 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2149 location of the raised exception.
2150
Victor Stinner313a1202010-06-11 23:56:51 +00002151- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2152 filenames and enable os.fsencode().
2153
Benjamin Peterson285a6892010-06-22 19:21:52 +00002154- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2155
Georg Brandl62069d32010-07-31 08:56:11 +00002156- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2157 interpreter with characters outside the Basic Multilingual Plane (higher than
2158 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002159
Georg Brandl62069d32010-07-31 08:56:11 +00002160- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2161 TypeError instead of giving a DeprecationWarning when a float is parsed using
2162 the 'L' code (for long long). (All other integer codes already raise
2163 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002164
Victor Stinner600d3be2010-06-10 12:00:55 +00002165- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2166 enable shortcuts for upper case encoding name. Add also a shortcut for
2167 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2168
Georg Brandl62069d32010-07-31 08:56:11 +00002169- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2170 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002171
2172- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002173 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002174 like bytearray.
2175
Georg Brandl62069d32010-07-31 08:56:11 +00002176- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002177 used anymore and it was never documented.
2178
Georg Brandl62069d32010-07-31 08:56:11 +00002179- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002180
Georg Brandl62069d32010-07-31 08:56:11 +00002181- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2182 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002183
Georg Brandl62069d32010-07-31 08:56:11 +00002184- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2185 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2186 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2187 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002188
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002189- Issue #8748: Fix two issues with comparisons between complex and integer
2190 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002191 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2192 (2) The comparison raised an OverflowError for large integers, leading to
2193 unpredictable exceptions when combining integers and complex objects in sets
2194 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002195
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002196- Issue #8766: Initialize _warnings module before importing the first module.
2197 Fix a crash if an empty directory called "encodings" exists in sys.path.
2198
Victor Stinner9ca9c252010-05-19 16:53:30 +00002199- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002200 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002201 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002202
Georg Brandl62069d32010-07-31 08:56:11 +00002203- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2204 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002205
Victor Stinnerae6265f2010-05-15 16:27:27 +00002206- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2207 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002208 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002209 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002210
Victor Stinner59e62db2010-05-15 13:14:32 +00002211- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002212 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002213
Victor Stinnerb744ba12010-05-15 12:27:16 +00002214- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002215 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002216 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2217
Victor Stinner0964ee12010-04-30 16:48:45 +00002218- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002219 PyUnicode_FromString() to support surrogates in the filename and use the right
2220 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002221
Georg Brandl8569e582010-05-19 20:57:08 +00002222- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2223
Georg Brandl62069d32010-07-31 08:56:11 +00002224- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002225
Benjamin Petersonfb886362010-04-24 18:21:17 +00002226- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2227 arguments.
2228
Victor Stinner14284c22010-04-23 12:02:30 +00002229- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002230 indirectly Python signal handlers anymore because mywrite() ignores exceptions
2231 (KeyboardInterrupt).

Victor Stinnerdcb24032010-04-22 12:08:36 +00002238
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00002239- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00002240 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002323- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002324 where the right hand operand is a set of constants, by turning the set into a

2326 against the constant instead of building a new set each time it is executed (a
2327 similar optimization already existed which turned a list of constants into a
2328 pre-built tuple). Patch and additional tests by Dave Malcolm.

2524 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2525 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002526 to match the behaviour of the other integer format codes.
2527

Georg Brandl62069d32010-07-31 08:56:11 +00002553- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2554 allocator will be automatically disabled when running under Valgrind. This
2555 gives improved memory leak detection when running under Valgrind, while taking
2556 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00002629- The default size of the re module's compiled regular expression cache has been
2630 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00002631 simply clearing the entire cache on overflow to forgetting the least recently
2632 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002633 applications that use a lot of regular expressions and limits the impact of
2634 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002646- Issue #7989: Added pure python implementation of the `datetime` module. The C
2647 module is renamed to `_datetime` and if available, overrides all classes
2648 defined in datetime with fast C impementation. Python implementation is based
2649 on the original python prototype for the datetime module by Tim Peters with
2650 minor modifications by the PyPy project. The test suite now tests `datetime`
2651 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00003048- Issue #2531: Comparison operations between floats and Decimal instances now
3049 return a result based on the numeric values of the operands; previously they
3050 returned an arbitrary result based on the relative ordering of id(float) and
3051 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3052 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003056- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003057 argument `-` which tells it to read files to compile from stdin. Each line is

3066 Fractions instance now raise TypeError instead of returning True/False. This
3067 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3068 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003111- The internals of the subprocess module on POSIX systems have been replaced by
3112 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3113 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003115- subprocess.Popen now has restore_signals and start_new_session features. The
3116 default of restore_signals=True is a new behavior compared to earlier Python
3117 versions. This means that signals such as SIGPIPE are not ignored by default
3118 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003204- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3205 position when calling `truncate()`. It would previously change the file
3206 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003207 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00003209- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00003210 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
3211 archive. The new implementation is significantly faster and can be wrapped in
3212 a :class:`io.BufferedReader` object for more speedups. It also solves an
3213 issue where interleaved calls to `read()` and `readline()` give wrong results.
3214 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00003549- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00003550 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
3551 PyPycLoader inherit from this class and provide implementations in relation to
3552 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00003553
Brett Cannon64ef00f2009-07-20 03:19:18 +00003554- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
3555 the documentation said it did even though the code in PyLoader relied on the
3556 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003611- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003612 compared to other unix systems. In particular, os.getgroups() does not reflect
3613 any changes made using os.setgroups() but basicly always returns the same
3614 information as the id command. os.getgroups() can now return more than 16
3615 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003616

Georg Brandl62069d32010-07-31 08:56:11 +00003640- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
3641 Prior to this change, timezone adjustment in utctimetuple() could produce
3642 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

3646 directive. When the ``%z`` directive is present in the format string, an
3647 aware ``datetime`` object is returned with ``tzinfo`` bound to a
3648 ``datetime.timezone`` instance constructed from the parsed offset. If both
3649 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
3650 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00003653 implementing ``datetime.tzinfo`` interface. Instances of the new class,
3654 ``datetime.timezone``, return fixed name and UTC offset from their
3655 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
3656 returns ``None``. A class attribute, ``utc`` contains an instance
3657 representing the UTC timezone. Original patch by Rafe Kaplan.

3971 threads could return successfully while some Thread objects were still

Antoine Pitrou61f77b52009-05-24 15:46:13 +00004181- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4182 than an int, which makes some operations possible under 64-bit Linux (e.g.
4183 DN_MULTISHOT with F_NOTIFY).
4184
Antoine Pitrou716c4442009-05-23 19:04:03 +00004185- Issue #5761: Add the name of the underlying file to the repr() of various

4190
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004191- Issue #1983: Fix functions taking or returning a process identifier to use
4192 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4193 a process identifier type wider than the standard C integer type.
4194

4206
Antoine Pitroue4501852009-05-14 18:55:55 +00004207- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4208 library. This means, for example, that opening an UTF-16 text file in
4209 append mode doesn't add a BOM at the end of the file if the file isn't
4210 empty.
4211
R. David Murray74b89242009-05-13 17:33:03 +00004212- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4213 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4214 corrects a pydoc regression.
4215
Georg Brandl5f90d792010-08-01 22:31:05 +00004216- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004217 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004258*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004259
4260Core and Builtins
4261-----------------
4262
Mark Dickinson865e01a2009-05-07 16:37:01 +00004263- Issue #5914: Add new C API function PyOS_string_to_double, and
4264 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4265
Eric Smith741191f2009-05-06 13:08:15 +00004266- Issue #3382: float.__format__, complex.__format__, and %-formatting
4267 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4268 affects nan -> NAN and inf -> INF.
4269
Mark Hammond5a607a32009-05-06 08:04:54 +00004270- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4271 in all operations, including splitdrive, split, etc. splitunc() now issues
4272 a PendingDeprecation warning.
4273
Eric Smith63376222009-05-05 14:04:18 +00004274- Issue #5920: For float.__format__, change the behavior with the
4275 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4276 to be like 'g' but with at least one decimal point and with a
4277 default precision of 12. Previously, the behavior the same but with
4278 a default precision of 6. This more closely matches str(), and
4279 reduces surprises when adding alignment flags to the empty
4280 presentation type. This also affects the new complex.__format__ in
4281 the same way.
4282
Martin v. Löwis011e8422009-05-05 04:43:17 +00004283- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4284
R. David Murrayb18500d2009-05-04 22:59:07 +00004285- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4286 shadowed by classtype's, even if it was None. property now
4287 inserts the __doc__ into the subclass instance __dict__.
4288
Antoine Pitrou244651a2009-05-04 18:56:13 +00004289- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4290 sequences. Patch by Nick Barnes and Victor Stinner.
4291
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004292- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004293
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004294- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4295 received a new method, detach(). detach() disconnects the underlying stream
4296 from the buffer or text IO and returns it.
4297
Mark Dickinson33841c32009-05-01 15:37:04 +00004298- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4299 floats with absolute value over 1e50. Also remove length
4300 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4301 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004302
Eric Smith741191f2009-05-06 13:08:15 +00004303- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004304 format(complex(1, 2./3), '.5') now produces a sensible result.
4305
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004306- Issue #5864: Fix empty format code formatting for floats so that it
4307 never gives more than the requested number of significant digits.
4308
Eric Smith6dc46f52009-04-27 20:39:49 +00004309- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4310 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4311
Eric Smithcc32a112009-04-26 21:35:14 +00004312- Issue #5835: Deprecate PyOS_ascii_formatd.
4313
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004314- Issue #4971: Fix titlecase for characters that are their own
4315 titlecase, but not their own uppercase.
4316
Benjamin Peterson193152c2009-04-25 01:08:45 +00004317- Issue #5283: Setting __class__ in __del__ caused a segfault.
4318
Mark Dickinsonad476da2009-04-23 19:14:16 +00004319- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4320 z involves nans, infs or negative zeros.
4321
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004322- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004323
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004324- Issue #1869 (and many duplicates): make round(x, n) correctly
4325 rounded for a float x, by using the decimal <-> binary conversions
4326 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4327 consistently agrees with format(x, '.2f').
4328
Benjamin Petersonae937c02009-04-18 20:54:08 +00004329- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4330 some builtin types.
4331
Eric Smith0923d1d2009-04-16 20:16:10 +00004332- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4333
Eric Smith35e84722009-04-16 20:21:28 +00004334- Issue #5515: str.format() type 'n' combined with commas and leading
4335 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004336
4337- Implement PEP 378, Format Specifier for Thousands Separator, for
4338 floats.
4339
Mark Dickinson3370cce2009-04-17 22:40:53 +00004340- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004341 1e11, not 1e12. This avoids printing 13 significant digits in
4342 situations where only 12 of them are correct. Example problem
4343 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4344 long time.)
4345
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004346- Issue #1580: On most platforms, use a 'short' float repr: for a
4347 finite float x, repr(x) now outputs a string based on the shortest
4348 sequence of decimal digits that rounds to x. Previous behaviour was
4349 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004350 Another minor difference is that the new repr switches to
4351 exponential notation at 1e16 instead of the previous 1e17; this
4352 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004353
4354 There's a new sys attribute sys.float_repr_style, which takes
4355 the value 'short' to indicate that we're using short float repr,
4356 and 'legacy' if the short float repr isn't available for one
4357 reason or another.
4358
4359 The float repr change involves incorporating David Gay's 'perfect
4360 rounding' code into the Python core (it's in Python/dtoa.c). As a
4361 secondary consequence, all string-to-float and float-to-string
4362 conversions (including all float formatting operations) will be
4363 correctly rounded on these platforms.
4364
Georg Brandl5f90d792010-08-01 22:31:05 +00004365 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004366 this change does not apply.
4367
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004368- Issue #5759: float() didn't call __float__ on str subclasses.
4369
Georg Brandlabc38772009-04-12 15:51:51 +00004370- The string.maketrans() function is deprecated; there is a new static method
4371 maketrans() on the bytes and bytearray classes. This removes confusion about
4372 the types string.maketrans() is supposed to work with, and mirrors the
4373 methods available on the str class.
4374
R. David Murraydc6da8a2009-04-09 22:16:43 +00004375- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4376 its clarity and its speed.
4377
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004378- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004379 to avoid compiler warnings.
4380
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004381- Issue #3739: The unicode-internal encoder now reports the number of characters
4382 consumed like any other encoder (instead of the number of bytes).

4540
Antoine Pitrou3a652b12009-03-23 18:52:06 +00004541- Issue #4688: Add a heuristic so that tuples and dicts containing only
4542 untrackable objects are not tracked by the garbage collector. This can
4543 reduce the size of collections and therefore the garbage collection overhead
4544 on long-running programs, depending on their particular use of datatypes.
4545

Lars Gustäbel42e00912009-03-22 20:34:29 +00004614- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
4615 forever on incomplete input. That caused tarfile.open() to hang when used
4616 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
4617 partial bzip2 compressed data.
4618
Mark Dickinson79f52032009-03-17 23:12:51 +00004619- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00004730 having been closed (for instance, a read() call could return some
4731 previously buffered data). Patch by Dmitry Vasiliev.
4732
Antoine Pitrou05608432009-01-09 18:53:14 +00004733- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4734 flag to work properly. Furthermore, when specifying -u, the text stdout
4735 and stderr streams have line-by-line buffering enabled (the default being
4736 to buffer arbitrary chunks of data).
4737
Raymond Hettinger35631532009-01-09 03:58:09 +00004738- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4739 instead of ints (reducing its size from 4 to 8 times thereby reducing
4740 Python's overall memory).
4741
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004742- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4743 an existing .py counterpart, override the co_filename attributes of all
4744 code objects if the original filename is obsolete (which can happen if the
4745 file has been renamed, moved, or if it is accessed through different paths).

4749 one byte. Also fixes the meaning of len() so that it returns the number of
4750 items, rather than the size in bytes.
4751
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004752- Issue #4075: Use OutputDebugStringW in Py_FatalError.

5139
Antoine Pitrou08838b62009-01-21 00:55:13 +00005140- Issue #5008: When a file is opened in append mode with the new IO library,
5141 do an explicit seek to the end of file (so that e.g. tell() returns the
5142 file size rather than 0). This is consistent with the behaviour of the

5173 appropriately when it is being used via socket.makefile() objects
5174 rather than delaying the close by waiting for garbage collection to do it.
5175
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005176- Issue #1696199: Add collections.Counter() for rapid and convenient
