208 of HTTP 1.1.
209
Armin Ronacher59531282011-01-22 13:44:22 +0000210- To match the behaviour of HTTP server, the HTTP client library now also

Georg Brandl255abdd2011-01-16 14:17:26 +0000304 continuation line in the formatted value has no leading white space and looks

306 is made for all headers in any serialized message at serialization time. This
307 provides protection against header injection attacks.

329 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +0000953- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of

Victor Stinnerf933e1a2010-10-20 22:58:25 +0000955 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +0000956 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +0000957 encoding and to encode command line arguments on this OS.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001070 incorrectly validated some non-compliant applications as WSGI compliant; if
1071 your app validates with Python <3.2b1+, but not on this version, it is likely
1072 the case that your app was not compliant.)

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001331- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001332 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001336- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1337 threads are still running. Instead, reinitialize the GIL on a second call to
1338 Py_Initialize().
1339
Georg Brandl27a28582010-10-10 09:49:21 +00001340- All SyntaxErrors now have a column offset and therefore a caret when the error
1341 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00001343- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

Nick Coghlan37ee8502010-12-03 14:26:13 +00001346- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00001349- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1350 with a non-empty format string. This is an effort to future-proof user
1351 code. If a derived class does not currently implement __format__ but later
1352 adds its own __format__, it would most likely break user code that had
1353 supplied a format string. This will be changed to a DeprecationWaring in
1354 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00001356- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1357 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1358 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 +00001360- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1361 functions from the libc caused the methods .upper() and lower() to become
1362 locale aware and created subtly wrong results.
1363
Georg Brandl27a28582010-10-10 09:49:21 +00001364- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001367- Issue #4617: Previously it was illegal to delete a name from the local
1368 namespace if it occurs as a free variable in a nested block. This limitation
1369 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1370
Georg Brandl27a28582010-10-10 09:49:21 +00001371- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1372 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1373 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1374 single character on UCS-2 builds.

1378 memoryview), and gain support for the context management protocol.
1379
Antoine Pitrou079ce542010-09-08 12:37:10 +00001380- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001409- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001410 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001411 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001412 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00001437 retry the select() loop instead of bailing out. This is because select() can
1438 incorrectly report a socket as ready for reading (for example, if it received
1439 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001519- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001520 it possible for the user to create self-referencing ordered dictionaries which
1521 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001522 approach of using weakref proxies so that reference cycles never get created
1523 in the first place.

1531 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1532 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00001538- The pprint module now supports printing OrderedDicts in their given order

Georg Brandl27a28582010-10-10 09:49:21 +00001544- Issue #9707: Rewritten reference implementation of threading.local which is
1545 friendlier towards reference cycles. This change is not normally visible
1546 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001547
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001548- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1549 still return the id of the parent process after it has exited. This process
1550 id may even have been reused by another unrelated process.
1551
Georg Brandl27a28582010-10-10 09:49:21 +00001552- Issue #9792: In case of connection failure, socket.create_connection() would
1553 swallow the exception and raise a new one, making it impossible to fetch the
1554 original errno, or to filter timeout errors. Now the original error is
1555 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001561- Updates to the random module:
1562
Georg Brandl27a28582010-10-10 09:49:21 +00001563 * Document which parts of the module are guaranteed to stay the same across
1564 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001565
Georg Brandl27a28582010-10-10 09:49:21 +00001566 * Update the seed() method to use all of the bits in a string instead of just
1567 the hash value. This makes better use of the seed value and assures the
1568 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001569
Georg Brandl27a28582010-10-10 09:49:21 +00001570 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1571 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1572 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001573

1725 return characters from the full Unicode range, even on narrow unicode builds
1726 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
1727 in Python is that unicodedata.numeric() now returns the correct value for
1728 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00001765- Issue #9416: Fix some issues with complex formatting where the output with no
1766 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001767
1768 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Victor Stinner8182b712010-07-28 00:40:58 +00002101- Issue #8991: convertbuffer() rejects discontigious buffers.
2102

2107
Ezio Melotti57221d02010-07-01 07:32:02 +00002108- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002109 start byte and the continuation byte(s) are now considered invalid, instead of
2110 the number of bytes specified by the start byte. E.g.:
2111 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2112 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2113 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2114 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002116- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2117 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00002128- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2129 dealing with unary minus applied to a constant. The removed code was mutating
2130 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002131
Victor Stinner554f3f02010-06-16 23:33:54 +00002132- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002133 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002134 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002135 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002136
Victor Stinner25e8ec42010-06-25 00:02:38 +00002137- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2138 "w*" format instead. Add tests for "w*" format.
2139
Victor Stinner06e49dd2010-06-13 18:21:50 +00002140- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002141 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002142 string formats.
2143
Georg Brandl62069d32010-07-31 08:56:11 +00002144- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002145 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2146 location of the raised exception.
2147
Victor Stinner313a1202010-06-11 23:56:51 +00002148- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2149 filenames and enable os.fsencode().
2150
Benjamin Peterson285a6892010-06-22 19:21:52 +00002151- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2152
Georg Brandl62069d32010-07-31 08:56:11 +00002153- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2154 interpreter with characters outside the Basic Multilingual Plane (higher than
2155 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002156
Georg Brandl62069d32010-07-31 08:56:11 +00002157- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2158 TypeError instead of giving a DeprecationWarning when a float is parsed using
2159 the 'L' code (for long long). (All other integer codes already raise
2160 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002161
Victor Stinner600d3be2010-06-10 12:00:55 +00002162- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2163 enable shortcuts for upper case encoding name. Add also a shortcut for
2164 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2165
Georg Brandl62069d32010-07-31 08:56:11 +00002166- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2167 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002168
2169- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002170 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002171 like bytearray.
2172
Georg Brandl62069d32010-07-31 08:56:11 +00002173- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002174 used anymore and it was never documented.
2175
Georg Brandl62069d32010-07-31 08:56:11 +00002176- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002177
Georg Brandl62069d32010-07-31 08:56:11 +00002178- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2179 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002180
Georg Brandl62069d32010-07-31 08:56:11 +00002181- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2182 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2183 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2184 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002185
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002186- Issue #8748: Fix two issues with comparisons between complex and integer
2187 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002188 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2189 (2) The comparison raised an OverflowError for large integers, leading to
2190 unpredictable exceptions when combining integers and complex objects in sets
2191 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002192
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002193- Issue #8766: Initialize _warnings module before importing the first module.
2194 Fix a crash if an empty directory called "encodings" exists in sys.path.
2195
Victor Stinner9ca9c252010-05-19 16:53:30 +00002196- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002197 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002198 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002199
Georg Brandl62069d32010-07-31 08:56:11 +00002200- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2201 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002202
Victor Stinnerae6265f2010-05-15 16:27:27 +00002203- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2204 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002205 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002206 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002207
Victor Stinner59e62db2010-05-15 13:14:32 +00002208- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002209 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002210
Victor Stinnerb744ba12010-05-15 12:27:16 +00002211- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002212 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002213 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2214
Victor Stinner0964ee12010-04-30 16:48:45 +00002215- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002216 PyUnicode_FromString() to support surrogates in the filename and use the right
2217 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002218
Georg Brandl8569e582010-05-19 20:57:08 +00002219- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2220
Georg Brandl62069d32010-07-31 08:56:11 +00002221- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002222
Benjamin Petersonfb886362010-04-24 18:21:17 +00002223- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2224 arguments.
2225
Victor Stinner14284c22010-04-23 12:02:30 +00002226- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002227 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00002233- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
2234 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00002235
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00002236- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00002237 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002320- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002321 where the right hand operand is a set of constants, by turning the set into a
2322 frozenset and pre-building it as a constant. The comparison operation is made
2323 against the constant instead of building a new set each time it is executed (a
2324 similar optimization already existed which turned a list of constants into a
2325 pre-built tuple). Patch and additional tests by Dave Malcolm.

Georg Brandl62069d32010-07-31 08:56:11 +00002626- The default size of the re module's compiled regular expression cache has been

Antoine Pitrou3060c452010-08-13 16:27:38 +00002628 simply clearing the entire cache on overflow to forgetting the least recently
2629 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002630 applications that use a lot of regular expressions and limits the impact of
2631 the performance hit anytime the cache is exceeded.

2644 module is renamed to `_datetime` and if available, overrides all classes
2645 defined in datetime with fast C impementation. Python implementation is based
2646 on the original python prototype for the datetime module by Tim Peters with
2647 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00003040- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3041 InvalidOperation instead of returning False. (Comparisons involving a quiet
3042 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3043 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003045- Issue #2531: Comparison operations between floats and Decimal instances now
3046 return a result based on the numeric values of the operands; previously they
3047 returned an arbitrary result based on the relative ordering of id(float) and
3048 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3049 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003053- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003054 argument `-` which tells it to read files to compile from stdin. Each line is
3055 read on demand and the named file is compiled immediately. (Original patch by
3056 Piotr Ożarowski).

3063 Fractions instance now raise TypeError instead of returning True/False. This
3064 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3065 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003108- The internals of the subprocess module on POSIX systems have been replaced by
3109 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3110 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003112- subprocess.Popen now has restore_signals and start_new_session features. The
3113 default of restore_signals=True is a new behavior compared to earlier Python
3114 versions. This means that signals such as SIGPIPE are not ignored by default
3115 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003201- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3202 position when calling `truncate()`. It would previously change the file
3203 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003204 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00003206- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00003207 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
3208 archive. The new implementation is significantly faster and can be wrapped in
3209 a :class:`io.BufferedReader` object for more speedups. It also solves an
3210 issue where interleaved calls to `read()` and `readline()` give wrong results.
3211 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00003546- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00003547 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and

Brett Cannon64ef00f2009-07-20 03:19:18 +00003551- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
3552 the documentation said it did even though the code in PyLoader relied on the
3553 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003608- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003609 compared to other unix systems. In particular, os.getgroups() does not reflect
3610 any changes made using os.setgroups() but basicly always returns the same
3611 information as the id command. os.getgroups() can now return more than 16
3612 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003613

3638 Prior to this change, timezone adjustment in utctimetuple() could produce
3639 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

3643 directive. When the ``%z`` directive is present in the format string, an
3644 aware ``datetime`` object is returned with ``tzinfo`` bound to a
3645 ``datetime.timezone`` instance constructed from the parsed offset. If both
3646 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
3647 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00003650 implementing ``datetime.tzinfo`` interface. Instances of the new class,
3651 ``datetime.timezone``, return fixed name and UTC offset from their
3652 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
3653 returns ``None``. A class attribute, ``utc`` contains an instance
3654 representing the UTC timezone. Original patch by Rafe Kaplan.

Antoine Pitrou61f77b52009-05-24 15:46:13 +00004178- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4179 than an int, which makes some operations possible under 64-bit Linux (e.g.
4180 DN_MULTISHOT with F_NOTIFY).
4181
Antoine Pitrou716c4442009-05-23 19:04:03 +00004182- Issue #5761: Add the name of the underlying file to the repr() of various

4187
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004188- Issue #1983: Fix functions taking or returning a process identifier to use
4189 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4190 a process identifier type wider than the standard C integer type.
4191

4203
Antoine Pitroue4501852009-05-14 18:55:55 +00004204- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4205 library. This means, for example, that opening an UTF-16 text file in
4206 append mode doesn't add a BOM at the end of the file if the file isn't
4207 empty.
4208
R. David Murray74b89242009-05-13 17:33:03 +00004209- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4210 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4211 corrects a pydoc regression.
4212
Georg Brandl5f90d792010-08-01 22:31:05 +00004213- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004214 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004256
4257Core and Builtins
4258-----------------
4259
Mark Dickinson865e01a2009-05-07 16:37:01 +00004260- Issue #5914: Add new C API function PyOS_string_to_double, and
4261 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4262
Eric Smith741191f2009-05-06 13:08:15 +00004263- Issue #3382: float.__format__, complex.__format__, and %-formatting
4264 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4265 affects nan -> NAN and inf -> INF.
4266
Mark Hammond5a607a32009-05-06 08:04:54 +00004267- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4268 in all operations, including splitdrive, split, etc. splitunc() now issues
4269 a PendingDeprecation warning.
4270
Eric Smith63376222009-05-05 14:04:18 +00004271- Issue #5920: For float.__format__, change the behavior with the
4272 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4273 to be like 'g' but with at least one decimal point and with a
4274 default precision of 12. Previously, the behavior the same but with
4275 a default precision of 6. This more closely matches str(), and
4276 reduces surprises when adding alignment flags to the empty
4277 presentation type. This also affects the new complex.__format__ in
4278 the same way.
4279
Martin v. Löwis011e8422009-05-05 04:43:17 +00004280- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4281
R. David Murrayb18500d2009-05-04 22:59:07 +00004282- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4283 shadowed by classtype's, even if it was None. property now
4284 inserts the __doc__ into the subclass instance __dict__.
4285
Antoine Pitrou244651a2009-05-04 18:56:13 +00004286- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4287 sequences. Patch by Nick Barnes and Victor Stinner.
4288
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004289- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004290
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004291- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4292 received a new method, detach(). detach() disconnects the underlying stream
4293 from the buffer or text IO and returns it.
4294
Mark Dickinson33841c32009-05-01 15:37:04 +00004295- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4296 floats with absolute value over 1e50. Also remove length
4297 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4298 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004299
Eric Smith741191f2009-05-06 13:08:15 +00004300- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004301 format(complex(1, 2./3), '.5') now produces a sensible result.
4302
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004303- Issue #5864: Fix empty format code formatting for floats so that it
4304 never gives more than the requested number of significant digits.
4305
Eric Smith6dc46f52009-04-27 20:39:49 +00004306- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4307 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4308
Eric Smithcc32a112009-04-26 21:35:14 +00004309- Issue #5835: Deprecate PyOS_ascii_formatd.
4310
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004311- Issue #4971: Fix titlecase for characters that are their own
4312 titlecase, but not their own uppercase.
4313
Benjamin Peterson193152c2009-04-25 01:08:45 +00004314- Issue #5283: Setting __class__ in __del__ caused a segfault.
4315
Mark Dickinsonad476da2009-04-23 19:14:16 +00004316- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4317 z involves nans, infs or negative zeros.
4318
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004319- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004320
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004321- Issue #1869 (and many duplicates): make round(x, n) correctly
4322 rounded for a float x, by using the decimal <-> binary conversions
4323 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4324 consistently agrees with format(x, '.2f').
4325
Benjamin Petersonae937c02009-04-18 20:54:08 +00004326- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4327 some builtin types.
4328
Eric Smith0923d1d2009-04-16 20:16:10 +00004329- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4330
Eric Smith35e84722009-04-16 20:21:28 +00004331- Issue #5515: str.format() type 'n' combined with commas and leading
4332 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004333
4334- Implement PEP 378, Format Specifier for Thousands Separator, for
4335 floats.
4336
Mark Dickinson3370cce2009-04-17 22:40:53 +00004337- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004338 1e11, not 1e12. This avoids printing 13 significant digits in
4339 situations where only 12 of them are correct. Example problem
4340 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4341 long time.)
4342
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004343- Issue #1580: On most platforms, use a 'short' float repr: for a
4344 finite float x, repr(x) now outputs a string based on the shortest
4345 sequence of decimal digits that rounds to x. Previous behaviour was
4346 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004347 Another minor difference is that the new repr switches to
4348 exponential notation at 1e16 instead of the previous 1e17; this
4349 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004350
4351 There's a new sys attribute sys.float_repr_style, which takes
4352 the value 'short' to indicate that we're using short float repr,
4353 and 'legacy' if the short float repr isn't available for one
4354 reason or another.
4355
4356 The float repr change involves incorporating David Gay's 'perfect
4357 rounding' code into the Python core (it's in Python/dtoa.c). As a
4358 secondary consequence, all string-to-float and float-to-string
4359 conversions (including all float formatting operations) will be
4360 correctly rounded on these platforms.
4361
Georg Brandl5f90d792010-08-01 22:31:05 +00004362 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004363 this change does not apply.
4364
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004365- Issue #5759: float() didn't call __float__ on str subclasses.
4366
Georg Brandlabc38772009-04-12 15:51:51 +00004367- The string.maketrans() function is deprecated; there is a new static method
4368 maketrans() on the bytes and bytearray classes. This removes confusion about
4369 the types string.maketrans() is supposed to work with, and mirrors the
4370 methods available on the str class.
4371
R. David Murraydc6da8a2009-04-09 22:16:43 +00004372- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4373 its clarity and its speed.
4374
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004375- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004376 to avoid compiler warnings.
4377
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004378- Issue #3739: The unicode-internal encoder now reports the number of characters
4379 consumed like any other encoder (instead of the number of bytes).

4536 the end sys.path, for compatibility with the system install of Python.
4537
Antoine Pitrou3a652b12009-03-23 18:52:06 +00004538- Issue #4688: Add a heuristic so that tuples and dicts containing only
4539 untrackable objects are not tracked by the garbage collector. This can
4540 reduce the size of collections and therefore the garbage collection overhead
4541 on long-running programs, depending on their particular use of datatypes.
4542

4610
Lars Gustäbel42e00912009-03-22 20:34:29 +00004611- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
4612 forever on incomplete input. That caused tarfile.open() to hang when used
4613 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
4614 partial bzip2 compressed data.
4615
Mark Dickinson79f52032009-03-17 23:12:51 +00004616- Issue #2110: Add support for thousands separator and 'n' type

4684 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
4685 evaluation loop is compiled with a new dispatch mechanism which gives
4686 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8043cf82009-01-09 19:54:29 +00004727 having been closed (for instance, a read() call could return some
4728 previously buffered data). Patch by Dmitry Vasiliev.
4729
Antoine Pitrou05608432009-01-09 18:53:14 +00004730- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4731 flag to work properly. Furthermore, when specifying -u, the text stdout
4732 and stderr streams have line-by-line buffering enabled (the default being
4733 to buffer arbitrary chunks of data).
4734
Raymond Hettinger35631532009-01-09 03:58:09 +00004735- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4736 instead of ints (reducing its size from 4 to 8 times thereby reducing
4737 Python's overall memory).
4738
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004739- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4740 an existing .py counterpart, override the co_filename attributes of all
4741 code objects if the original filename is obsolete (which can happen if the
4742 file has been renamed, moved, or if it is accessed through different paths).
4743 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4744
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004745- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4746 one byte. Also fixes the meaning of len() so that it returns the number of
4747 items, rather than the size in bytes.
4748
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004749- Issue #4075: Use OutputDebugStringW in Py_FatalError.

5136
Antoine Pitrou08838b62009-01-21 00:55:13 +00005137- Issue #5008: When a file is opened in append mode with the new IO library,
5138 do an explicit seek to the end of file (so that e.g. tell() returns the
5139 file size rather than 0). This is consistent with the behaviour of the

5170 appropriately when it is being used via socket.makefile() objects
5171 rather than delaying the close by waiting for garbage collection to do it.
5172
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005173- Issue #1696199: Add collections.Counter() for rapid and convenient
