Ned Deily657b2de2011-06-28 19:51:30 -0700329- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
330 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
331 interpreter process. This could cause failures in non-Distutils subprocesses
332 and was unreliable since tests or user programs could modify the interpreter
333 environment after Distutils set it. Instead, have Distutils set the the
334 deployment target only in the environment of each build subprocess. It is
335 still possible to globally override the default by setting
336 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
337 greater or equal to the default value, the value with which the interpreter
338 was built.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001835 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001836 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001837 encoding and to encode command line arguments on this OS.

2179-----------------
2180
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002181- Issue #10068: Global objects which have reference cycles with their module's
2182 dict are now cleared again. This causes issue #7140 to appear again.
2183
Victor Stinner257d38f2010-10-09 10:12:11 +00002184- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002185 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002186
Georg Brandl27a28582010-10-10 09:49:21 +00002187- ast.literal_eval() can now handle negative numbers. It is also a little more
2188 liberal in what it accepts without compromising the safety of the evaluation.
2189 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002190
Benjamin Peterson970d1882010-10-02 17:55:47 +00002191- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2192 result metaclasses can now be ABCs (see #9533).
2193
Victor Stinneraef57e32010-10-02 11:50:49 +00002194- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2195
Victor Stinner5593d8a2010-10-02 11:11:27 +00002196- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002197 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2198 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002199
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002200- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002201 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002202
Victor Stinner137c34c2010-09-29 10:25:54 +00002203- Issue #9979: Create function PyUnicode_AsWideCharString().
2204
Brett Cannon5305a992010-09-27 21:08:38 +00002205- Issue #7397: Mention that importlib.import_module() is probably what someone
2206 really wants to be using in __import__'s docstring.
2207
Georg Brandl27a28582010-10-10 09:49:21 +00002208- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2209 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002210
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002211- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002212 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002213
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002214- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2215
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002216- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2217 threads are still running. Instead, reinitialize the GIL on a second call to
2218 Py_Initialize().
2219
Georg Brandl27a28582010-10-10 09:49:21 +00002220- All SyntaxErrors now have a column offset and therefore a caret when the error
2221 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002222
Brett Cannonbc2eff32010-09-19 21:39:02 +00002223- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2224 module that was imported, but instead gets the module from sys.modules.
2225
Nick Coghlan37ee8502010-12-03 14:26:13 +00002226- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002227 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002228
Georg Brandl27a28582010-10-10 09:49:21 +00002229- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2230 with a non-empty format string. This is an effort to future-proof user
2231 code. If a derived class does not currently implement __format__ but later
2232 adds its own __format__, it would most likely break user code that had
2233 supplied a format string. This will be changed to a DeprecationWaring in
2234 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002235
Antoine Pitrou1df15362010-09-13 14:16:46 +00002236- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2237 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2238 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2239
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002240- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2241 functions from the libc caused the methods .upper() and lower() to become
2242 locale aware and created subtly wrong results.
2243
Georg Brandl27a28582010-10-10 09:49:21 +00002244- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2245 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002246
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002247- Issue #4617: Previously it was illegal to delete a name from the local
2248 namespace if it occurs as a free variable in a nested block. This limitation
2249 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2250
Georg Brandl27a28582010-10-10 09:49:21 +00002251- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2252 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2253 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2254 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002255
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002256- Issue #9757: memoryview objects get a release() method to release the
2257 underlying buffer (previously this was only done when deallocating the
2258 memoryview), and gain support for the context management protocol.
2259
Antoine Pitrou079ce542010-09-08 12:37:10 +00002260- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2261 thread-local storage key.
2262

2264-------
2265
Éric Araujo0cfba092010-11-08 21:48:23 +00002266- Issue #2236: distutils' mkpath ignored the mode parameter.
2267
Éric Araujoe7cf9542010-11-06 15:01:07 +00002268- Fix typo in one sdist option (medata-check).
2269
2270- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
2271
2272- Issue #1718574: Fix options that were supposed to accept arguments but did
2273 not in build_clib.
2274
Antoine Pitroudbec7802010-10-10 09:37:12 +00002275- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2276
R. David Murray96fd54e2010-10-08 15:55:28 +00002277- Issue #4661: email can now parse bytes input and generate either converted
2278 7bit output or bytes output. Email version bumped to 5.1.0.
2279
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002280- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2281 verification for higher-level protocols.
2282
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002283- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2284 after the file is closed. Patch by Jeffrey Finkelstein.
2285
Éric Araujo6108bf52010-10-04 23:52:37 +00002286- Issue #9042: Fix interaction of custom translation classes and caching in
2287 gettext.
2288
Éric Araujoef777bd2010-10-05 00:04:20 +00002289- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002290 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002291 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002292 replacement for old handle_accept() and avoids the user to call accept()
2293 directly.
2294
Lars Gustäbel331b8002010-10-04 15:18:47 +00002295- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2296 gname field.
2297
Georg Brandl27a28582010-10-10 09:49:21 +00002298- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2299 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002300
R. David Murray5397e862010-10-02 15:58:26 +00002301- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2302 characters that appear inside quoted strings in email addresses.
2303
Georg Brandl27a28582010-10-10 09:49:21 +00002304- Issue #10004: quoprimime no longer generates a traceback when confronted with
2305 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002306
Georg Brandl27a28582010-10-10 09:49:21 +00002307- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2308 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002309
Georg Brandl27a28582010-10-10 09:49:21 +00002310- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2311 conforms to the philosophy of bytes and unicode separation in Python 3. A
2312 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002313
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002314- Issue #9962: GzipFile now has the peek() method.
2315
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002316- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002317 retry the select() loop instead of bailing out. This is because select() can
2318 incorrectly report a socket as ready for reading (for example, if it received
2319 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002320
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002321- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2322
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002323- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002324 received. Now sendall() properly calls signal handlers if necessary, and
2325 retries sending if these returned successfully, including on sockets with a
2326 timeout.

2355
Georg Brandl27a28582010-10-10 09:49:21 +00002356- logging: Changed LoggerAdapter implementation internally, to make it easier to
2357 subclass in a useful way.

Georg Brandl27a28582010-10-10 09:49:21 +00002366 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002400 it possible for the user to create self-referencing ordered dictionaries which
2401 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002402 approach of using weakref proxies so that reference cycles never get created

Georg Brandl27a28582010-10-10 09:49:21 +00002409- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2410 environment variable to set the filesystem encoding at Python startup.
2411 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2412 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002414- Issue #9410: Various optimizations to the pickle module, leading to speedups
2415 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2416 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002417
Georg Brandl27a28582010-10-10 09:49:21 +00002418- The pprint module now supports printing OrderedDicts in their given order
2419 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002421- Logging: Added QueueHandler class to facilitate logging usage with
2422 multiprocessing.
2423
Georg Brandl27a28582010-10-10 09:49:21 +00002424- Issue #9707: Rewritten reference implementation of threading.local which is
2425 friendlier towards reference cycles. This change is not normally visible
2426 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002427
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002428- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2429 still return the id of the parent process after it has exited. This process
2430 id may even have been reused by another unrelated process.
2431
Georg Brandl27a28582010-10-10 09:49:21 +00002432- Issue #9792: In case of connection failure, socket.create_connection() would
2433 swallow the exception and raise a new one, making it impossible to fetch the
2434 original errno, or to filter timeout errors. Now the original error is
2435 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002437- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2438 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2439 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002441- Updates to the random module:
2442
Georg Brandl27a28582010-10-10 09:49:21 +00002443 * Document which parts of the module are guaranteed to stay the same across
2444 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002446 * Update the seed() method to use all of the bits in a string instead of just
2447 the hash value. This makes better use of the seed value and assures the
2448 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002449
Georg Brandl27a28582010-10-10 09:49:21 +00002450 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2451 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2452 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002453
2454 * Improved documentation of arguments to randrange(). Issue #9379.

2460 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2461 given warning type was triggered by the code under test.

2465 writable.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002469- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002470 unsupported operation is attempted (for example, writing to a file open only
2471 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002473- hashlib has two new constant attributes: algorithms_guaranteed and
2474 algorithms_avaiable that respectively list the names of hash algorithms
2475 guaranteed to exist in all Python implementations and the names of hash
2476 algorithms available in the current process.
2477
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002478- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002581- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2582 now removed, since their effect was inexistent in 3.x (the default encoding is

2605 return characters from the full Unicode range, even on narrow unicode builds
2606 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2607 in Python is that unicodedata.numeric() now returns the correct value for
2608 large code points, and repr() may consider more characters as printable.
2609
Victor Stinner6c00c142010-08-17 23:37:11 +00002610- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002627 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2628 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002645- Issue #9416: Fix some issues with complex formatting where the output with no
2646 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002647
2648 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00002988- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002989 start byte and the continuation byte(s) are now considered invalid, instead of
2990 the number of bytes specified by the start byte. E.g.:
2991 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2992 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2993 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2994 returned a single u'\ufffd'.

3009 dealing with unary minus applied to a constant. The removed code was mutating
3010 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003014 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003015 handlers. Patch written by Mark Hammond.

Victor Stinner25e8ec42010-06-25 00:02:38 +00003017- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3018 "w*" format instead. Add tests for "w*" format.
3019
Victor Stinner06e49dd2010-06-13 18:21:50 +00003020- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003021 formats if the string contains a null byte/character. Write unit tests for

3023
Georg Brandl62069d32010-07-31 08:56:11 +00003024- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003025 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3026 location of the raised exception.
3027
Victor Stinner313a1202010-06-11 23:56:51 +00003028- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3029 filenames and enable os.fsencode().
3030
Benjamin Peterson285a6892010-06-22 19:21:52 +00003031- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3032
Georg Brandl62069d32010-07-31 08:56:11 +00003033- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3034 interpreter with characters outside the Basic Multilingual Plane (higher than
3035 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003036
Georg Brandl62069d32010-07-31 08:56:11 +00003037- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3038 TypeError instead of giving a DeprecationWarning when a float is parsed using
3039 the 'L' code (for long long). (All other integer codes already raise
3040 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003041
Victor Stinner600d3be2010-06-10 12:00:55 +00003042- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3043 enable shortcuts for upper case encoding name. Add also a shortcut for
3044 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3045
Georg Brandl62069d32010-07-31 08:56:11 +00003046- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3047 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003048
3049- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003050 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003051 like bytearray.
3052
Georg Brandl62069d32010-07-31 08:56:11 +00003053- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003054 used anymore and it was never documented.
3055
Georg Brandl62069d32010-07-31 08:56:11 +00003056- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003060
Georg Brandl62069d32010-07-31 08:56:11 +00003061- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3062 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3063 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3064 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003065
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003066- Issue #8748: Fix two issues with comparisons between complex and integer
3067 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003068 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3069 (2) The comparison raised an OverflowError for large integers, leading to
3070 unpredictable exceptions when combining integers and complex objects in sets
3071 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003072
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003073- Issue #8766: Initialize _warnings module before importing the first module.
3074 Fix a crash if an empty directory called "encodings" exists in sys.path.
3075
Victor Stinner9ca9c252010-05-19 16:53:30 +00003076- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003077 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003078 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003079
Georg Brandl62069d32010-07-31 08:56:11 +00003080- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3081 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003082
Victor Stinnerae6265f2010-05-15 16:27:27 +00003083- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3084 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003085 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003086 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003087
Victor Stinner59e62db2010-05-15 13:14:32 +00003088- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003089 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003090
Victor Stinnerb744ba12010-05-15 12:27:16 +00003091- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003092 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003093 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3094
Victor Stinner0964ee12010-04-30 16:48:45 +00003095- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003096 PyUnicode_FromString() to support surrogates in the filename and use the right
3097 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003099- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3100
Georg Brandl62069d32010-07-31 08:56:11 +00003101- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003102
Benjamin Petersonfb886362010-04-24 18:21:17 +00003103- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3104 arguments.

3375 `va_copy`, but available on all python platforms.
3376
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003377- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3378 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3401 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3402 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003403 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003413- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3414 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3415 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00003430- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3431 allocator will be automatically disabled when running under Valgrind. This
3432 gives improved memory leak detection when running under Valgrind, while taking
3433 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003508 simply clearing the entire cache on overflow to forgetting the least recently
3509 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003510 applications that use a lot of regular expressions and limits the impact of
3511 the performance hit anytime the cache is exceeded.

3525 defined in datetime with fast C impementation. Python implementation is based
3526 on the original python prototype for the datetime module by Tim Peters with
3527 minor modifications by the PyPy project. The test suite now tests `datetime`

R. David Murrayad78d152010-04-27 02:45:53 +00003800- Issue #6656: fix locale.format_string to handle escaped percents
3801 and mappings.
3802
Georg Brandl62069d32010-07-31 08:56:11 +00003803- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3804 the method could block indefinitely if called just before the event loop
3805 started running. This also fixes the occasional freezes witnessed in
3806 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00003808- Issue #8524: When creating an SSL socket, the timeout value of the original
3809 socket wasn't retained (instead, a socket with a positive timeout would be
3810 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003811
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003812- Issue #5103: SSL handshake would ignore the socket timeout and block
3813 indefinitely if the other end didn't respond.
3814
Georg Brandl62069d32010-07-31 08:56:11 +00003815- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3816 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003817
Georg Brandl62069d32010-07-31 08:56:11 +00003818- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
3819 bytes strings for environment keys and values.

Georg Brandl62069d32010-07-31 08:56:11 +00003827- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3828 string "python" as the *ident*. openlog() arguments are all optional and
3829 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003830
Georg Brandl62069d32010-07-31 08:56:11 +00003831- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3832 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003833 wanting to continue using the socket in clear-text mode, by disabling
3834 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
3835
Antoine Pitrou7062db82010-04-22 13:30:10 +00003836- Issue #8496: make mailcap.lookup() always return a list, rather than an
3837 iterator. Patch by Gregory Nofi.

3841
Georg Brandl62069d32010-07-31 08:56:11 +00003842- Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl
3843 extension, such that verification of some SSL certificates doesn't fail
3844 because of an "unknown algorithm".
Antoine Pitroufec12ff2010-04-21 19:46:23 +00003845
Tarek Ziadéfb437512010-04-20 08:57:33 +00003846- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +00003867- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
3868 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
3869
Victor Stinner0e59cc32010-04-16 23:49:32 +00003870- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
3871 the current working directory.
3872
Victor Stinner5bfe1462010-04-16 13:28:05 +00003873- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
Georg Brandl62069d32010-07-31 08:56:11 +00003874 using backslashreplace error handler.
Victor Stinner5bfe1462010-04-16 13:28:05 +00003875
Georg Brandl62069d32010-07-31 08:56:11 +00003876- Issue #8412: os.system() now accepts bytes, bytearray and str with surrogates.
Victor Stinnercfa72782010-04-16 11:45:13 +00003877
Senthil Kumaranad02d232010-04-16 03:02:13 +00003878- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
3879 Locke and Hans Ulrich Niedermann.
3880
R. David Murrayd48739f2010-04-14 18:59:18 +00003881- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
3882
Georg Brandl62069d32010-07-31 08:56:11 +00003883- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003884 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003885 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003886
Victor Stinner485fb562010-04-13 11:07:24 +00003887- Issue #8383: pickle and pickletools use surrogatepass error handler when
3888 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00003889 Python 2.x and 3.x.
Victor Stinner485fb562010-04-13 11:07:24 +00003890
R. David Murrayb2416e52010-04-12 16:58:02 +00003891- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003892 filename and date, conforming to the 'standards' they were originally designed
3893 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00003894
R. David Murrayef3d6bd2010-04-12 14:48:58 +00003895- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
Georg Brandl62069d32010-07-31 08:56:11 +00003896 character sets will now consistently use a Content-Transfer-Encoding of 7bit
3897 rather than sometimes being marked as 8bit.

3903 cover recent locale changes and additions.
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +00003904
Antoine Pitrou04f6a322010-04-05 21:40:07 +00003905- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00003906 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3907 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00003908
Raymond Hettingerc50846a2010-04-05 18:56:31 +00003909- Add functools.total_ordering() and functools.cmp_to_key().
3910
Georg Brandl62069d32010-07-31 08:56:11 +00003911- Issue #8257: The Decimal construct now accepts a float instance directly,
3912 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003913
3914 >>> Decimal(1.1)
3915 Decimal('1.100000000000000088817841970012523233890533447265625')
3916
Georg Brandl62069d32010-07-31 08:56:11 +00003917- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3918 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00003919
Georg Brandl62069d32010-07-31 08:56:11 +00003920- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3921 InvalidOperation instead of returning False. (Comparisons involving a quiet
3922 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3923 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003924
Georg Brandl62069d32010-07-31 08:56:11 +00003925- Issue #2531: Comparison operations between floats and Decimal instances now
3926 return a result based on the numeric values of the operands; previously they
3927 returned an arbitrary result based on the relative ordering of id(float) and
3928 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3929 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003930
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003931- Added a subtract() method to collections.Counter().
3932
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003933- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003934 argument `-` which tells it to read files to compile from stdin. Each line is
3935 read on demand and the named file is compiled immediately. (Original patch by
3936 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003937
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003938- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3939 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003940 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003941
Georg Brandl62069d32010-07-31 08:56:11 +00003942- Comparisons using one of <, <=, >, >= between a complex instance and a
3943 Fractions instance now raise TypeError instead of returning True/False. This
3944 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3945 <=> complex, and complex <=> complex comparisons.
Mark Dickinsonab4d63b2010-03-27 11:16:00 +00003946
Georg Brandl62069d32010-07-31 08:56:11 +00003947- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some
3948 methods (such as oss_mixer_device.fileno()) were not available. Initial patch
3949 by Bertrand Janin.

Florent Xiclunafd1b0932010-03-28 00:25:02 +00003951- Issue #8205: Remove the "Modules" directory from sys.path when Python is
3952 running from the build directory (POSIX only).
3953
Antoine Pitrou910bd512010-03-22 20:11:09 +00003954- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003955 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3956 silenced.
Antoine Pitrou910bd512010-03-22 20:11:09 +00003957
Georg Brandl62069d32010-07-31 08:56:11 +00003958- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3959 is running in WOW64 mode on 64 bit Windows.

Antoine Pitrou3c0fac22010-03-26 19:36:14 +00003961- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3962 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3963 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +00003964
Victor Stinnere3a1f6d2010-03-22 01:58:35 +00003965- Issue #4282: Fix the main function of the profile module for a non-ASCII

3972
Benjamin Peterson00888932010-03-18 22:37:38 +00003973- Issue #8168: py_compile now handles files with utf-8 BOMS.
3974
Benjamin Peterson689a5582010-03-18 22:29:52 +00003975- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
3976 detected.

Georg Brandl62069d32010-07-31 08:56:11 +00003988- The internals of the subprocess module on POSIX systems have been replaced by
3989 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3990 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003991
Georg Brandl62069d32010-07-31 08:56:11 +00003992- subprocess.Popen now has restore_signals and start_new_session features. The
3993 default of restore_signals=True is a new behavior compared to earlier Python
3994 versions. This means that signals such as SIGPIPE are not ignored by default
3995 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00003996

Gerhard Häringf9cee222010-03-05 15:20:03 +00004009- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
4010 bugs and allows loading SQLite extensions from shared libraries.
4011

Michael Foord34c94622010-02-10 15:51:42 +00004264- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
4265 argument added to the TextTestRunner constructor allowing a different result
4266 class to be used without having to subclass.

Antoine Pitrou434736a2009-11-10 18:46:01 +00004271- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004272 default when instantiating a `threading.RLock` object. This makes recursive
4273 locks as fast as regular non-recursive locks (previously, they were slower by
4274 10x to 15x).

4294 from stdin so that existing input does not confuse it and lead to incorrect
4295 entry or an IOError. It also properly flushes it afterwards to avoid the
4296 terminal echoing the input afterwards on OSes such as Solaris.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004488- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004489 compared to other unix systems. In particular, os.getgroups() does not reflect
4490 any changes made using os.setgroups() but basicly always returns the same

4523 directive. When the ``%z`` directive is present in the format string, an
4524 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4525 ``datetime.timezone`` instance constructed from the parsed offset. If both
4526 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4527 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004529- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004530 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4531 ``datetime.timezone``, return fixed name and UTC offset from their
4532 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4533 returns ``None``. A class attribute, ``utc`` contains an instance
4534 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004859 runtest_inner in regrtest, with warnings if the called test modifies them, and

5005Core and Builtins
5006-----------------
5007
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00005008- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
5009 of the command line.
5010
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00005011- Issue #6012: Add cleanup support to O& argument parsing.
5012
Eric Smith41669ca2009-05-23 14:23:22 +00005013- Issue #6089: Fixed str.format with certain invalid field specifiers
5014 that would raise SystemError.
5015
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005016- Issue #5982: staticmethod and classmethod now expose the wrapped
5017 function with __func__.
5018
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005019- Added support for multiple context managers in the same with-statement.
5020 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00005021
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005022- Issue #5829: complex("1e500") no longer raises OverflowError. This
5023 makes it consistent with float("1e500") and interpretation of real
5024 and imaginary literals.
5025
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005026- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

R. David Murraydd226ea2009-05-13 12:27:21 +00005028- Issue #5994: the marshal module now has docstrings.
5029
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005030- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5031 (1) inf and nan strings with trailing whitespace were incorrectly
5032 rejected; (2) parsing of strings representing infinities and nans
5033 was locale aware; and (3) the interpretation of fromhex('-nan')
5034 didn't match that of float('-nan').
5035

5037-------
5038
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00005039- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
5040
R. David Murrayfb123912009-05-28 18:19:00 +00005041- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5042
R. David Murray1f1b9d32009-05-27 20:56:59 +00005043- Issue #6121: pydoc now ignores leading and trailing spaces in the
5044 argument to the 'help' function.
5045
Georg Brandlfaf41492009-05-26 18:31:11 +00005046- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
5047 arguments for strings with a space in them.
5048
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00005049- collections.namedtuple() was not working with the following field
5050 names: cls, self, tuple, itemgetter, and property.
5051
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005052- In unittest, using a skipping decorator on a class is now equivalent to
5053 skipping every test on the class. The ClassTestSuite class has been removed.
5054
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005055- Issue #6050: Don't fail extracting a directory from a zipfile if
5056 the directory already exists.
5057
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005058- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5059 than an int, which makes some operations possible under 64-bit Linux (e.g.
5060 DN_MULTISHOT with F_NOTIFY).
5061
Antoine Pitrou716c4442009-05-23 19:04:03 +00005062- Issue #5761: Add the name of the underlying file to the repr() of various
5063 IO objects.
5064
R. David Murraycaa27b72009-05-23 18:49:56 +00005065- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5066 by Musashi Tamura, tests by Marcin Bachry.
5067
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005068- Issue #1983: Fix functions taking or returning a process identifier to use
5069 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5070 a process identifier type wider than the standard C integer type.
5071
R. David Murray87e20742009-05-23 01:30:26 +00005072- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
5073 Patch by Farhan Ahmad, test by Marcin Bachry.
5074
Antoine Pitrou6e610062009-05-15 17:04:50 +00005075- Issue #2116: Weak references and weak dictionaries now support copy()ing and
5076 deepcopy()ing.
5077

5081
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00005082- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
5083
Antoine Pitroue4501852009-05-14 18:55:55 +00005084- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5085 library. This means, for example, that opening an UTF-16 text file in
5086 append mode doesn't add a BOM at the end of the file if the file isn't
5087 empty.
5088
R. David Murray74b89242009-05-13 17:33:03 +00005089- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5090 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5091 corrects a pydoc regression.
5092
Georg Brandl5f90d792010-08-01 22:31:05 +00005093- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005094 now it does. This also means getfp method now returns the real fp.
5095
Benjamin Peterson932073a2009-05-23 16:14:33 +00005096Installation
5097------------
5098
5099- Issue #6047: fullinstall has been removed because Python 3's executable will
5100 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00005101
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00005102- Lib/smtpd.py is no longer installed as a script.

5112
Benjamin Peterson744af442009-05-23 18:51:49 +00005113- The _functools and _locale modules are now built into the libpython shared
5114 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +00005115
Antoine Pitrou20327222009-05-24 20:39:11 +00005116Build
5117-----
5118
5119- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file

5124-----
5125
Georg Brandl5f90d792010-08-01 22:31:05 +00005126- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005127 tests on darwin even when the OS was installed on a case-sensitive
5128 filesystem. Also fixed tests that should not be run when
5129 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005132What's New in Python 3.1 beta 1?
5133================================
5134
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005135*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005136
5137Core and Builtins
5138-----------------
5139
Mark Dickinson865e01a2009-05-07 16:37:01 +00005140- Issue #5914: Add new C API function PyOS_string_to_double, and
5141 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5142
Eric Smith741191f2009-05-06 13:08:15 +00005143- Issue #3382: float.__format__, complex.__format__, and %-formatting
5144 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5145 affects nan -> NAN and inf -> INF.
5146
Mark Hammond5a607a32009-05-06 08:04:54 +00005147- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5148 in all operations, including splitdrive, split, etc. splitunc() now issues
5149 a PendingDeprecation warning.
5150
Eric Smith63376222009-05-05 14:04:18 +00005151- Issue #5920: For float.__format__, change the behavior with the
5152 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5153 to be like 'g' but with at least one decimal point and with a
5154 default precision of 12. Previously, the behavior the same but with
5155 a default precision of 6. This more closely matches str(), and
5156 reduces surprises when adding alignment flags to the empty
5157 presentation type. This also affects the new complex.__format__ in
5158 the same way.
5159
Martin v. Löwis011e8422009-05-05 04:43:17 +00005160- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5161
R. David Murrayb18500d2009-05-04 22:59:07 +00005162- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5163 shadowed by classtype's, even if it was None. property now
5164 inserts the __doc__ into the subclass instance __dict__.
5165
Antoine Pitrou244651a2009-05-04 18:56:13 +00005166- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5167 sequences. Patch by Nick Barnes and Victor Stinner.
5168
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005169- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005170
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005171- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5172 received a new method, detach(). detach() disconnects the underlying stream
5173 from the buffer or text IO and returns it.
5174
Mark Dickinson33841c32009-05-01 15:37:04 +00005175- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5176 floats with absolute value over 1e50. Also remove length
5177 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5178 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005179
Eric Smith741191f2009-05-06 13:08:15 +00005180- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005181 format(complex(1, 2./3), '.5') now produces a sensible result.
5182
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005183- Issue #5864: Fix empty format code formatting for floats so that it
5184 never gives more than the requested number of significant digits.
5185
Eric Smith6dc46f52009-04-27 20:39:49 +00005186- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5187 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5188
Eric Smithcc32a112009-04-26 21:35:14 +00005189- Issue #5835: Deprecate PyOS_ascii_formatd.
5190
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005191- Issue #4971: Fix titlecase for characters that are their own
5192 titlecase, but not their own uppercase.
5193
Benjamin Peterson193152c2009-04-25 01:08:45 +00005194- Issue #5283: Setting __class__ in __del__ caused a segfault.
5195
Mark Dickinsonad476da2009-04-23 19:14:16 +00005196- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5197 z involves nans, infs or negative zeros.
5198
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005199- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005200
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005201- Issue #1869 (and many duplicates): make round(x, n) correctly
5202 rounded for a float x, by using the decimal <-> binary conversions
5203 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5204 consistently agrees with format(x, '.2f').
5205
Benjamin Petersonae937c02009-04-18 20:54:08 +00005206- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5207 some builtin types.
5208
Eric Smith0923d1d2009-04-16 20:16:10 +00005209- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5210
Eric Smith35e84722009-04-16 20:21:28 +00005211- Issue #5515: str.format() type 'n' combined with commas and leading
5212 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005213
5214- Implement PEP 378, Format Specifier for Thousands Separator, for
5215 floats.
5216
Mark Dickinson3370cce2009-04-17 22:40:53 +00005217- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005218 1e11, not 1e12. This avoids printing 13 significant digits in
5219 situations where only 12 of them are correct. Example problem
5220 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5221 long time.)
5222
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005223- Issue #1580: On most platforms, use a 'short' float repr: for a
5224 finite float x, repr(x) now outputs a string based on the shortest
5225 sequence of decimal digits that rounds to x. Previous behaviour was
5226 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005227 Another minor difference is that the new repr switches to
5228 exponential notation at 1e16 instead of the previous 1e17; this
5229 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005230
5231 There's a new sys attribute sys.float_repr_style, which takes
5232 the value 'short' to indicate that we're using short float repr,
5233 and 'legacy' if the short float repr isn't available for one
5234 reason or another.
5235
5236 The float repr change involves incorporating David Gay's 'perfect
5237 rounding' code into the Python core (it's in Python/dtoa.c). As a
5238 secondary consequence, all string-to-float and float-to-string
5239 conversions (including all float formatting operations) will be
5240 correctly rounded on these platforms.
5241
Georg Brandl5f90d792010-08-01 22:31:05 +00005242 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005243 this change does not apply.
5244
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005245- Issue #5759: float() didn't call __float__ on str subclasses.
5246
Georg Brandlabc38772009-04-12 15:51:51 +00005247- The string.maketrans() function is deprecated; there is a new static method
5248 maketrans() on the bytes and bytearray classes. This removes confusion about
5249 the types string.maketrans() is supposed to work with, and mirrors the
5250 methods available on the str class.
5251
R. David Murraydc6da8a2009-04-09 22:16:43 +00005252- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5253 its clarity and its speed.
5254
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005255- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005256 to avoid compiler warnings.
5257
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005258- Issue #3739: The unicode-internal encoder now reports the number of characters
5259 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +00005271- Issue #5311: bdist_msi can now build packages that do not depend on a
5272 specific Python version.
5273
Raymond Hettingereb816952009-05-29 01:22:18 +00005274- Issue #5150: IDLE's format menu now has an option to strip trailing

5276
Vinay Sajipaffbd872009-06-11 10:11:47 +00005277- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Mark Dickinson8055afd2009-01-17 10:04:45 +00005580
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005581- Issue #4935: The overflow checking code in the expandtabs() method common
5582 to str, bytes and bytearray could be optimized away by the compiler, letting
5583 the interpreter segfault instead of raising an error.
5584
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005585- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5586 __next__ method.
5587
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005588- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5589 function no longer attempt to call the __long__ slot to convert an object
5590 to an integer. Only the __int__ and __trunc__ slots are examined.

5595
Antoine Pitrouab868312009-01-10 15:40:25 +00005596- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5597 common cases are optimized thanks to a dedicated fast path and a moderate
5598 amount of loop unrolling.
5599
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005600- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5601 collecting the oldest generation) so that allocating lots of objects without
5602 destroying them does not show quadratic performance. Based on a proposal by
5603 Martin von Löwis at
5604 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5605
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005606- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005607 having been closed (for instance, a read() call could return some
5608 previously buffered data). Patch by Dmitry Vasiliev.
5609
Antoine Pitrou05608432009-01-09 18:53:14 +00005610- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5611 flag to work properly. Furthermore, when specifying -u, the text stdout
5612 and stderr streams have line-by-line buffering enabled (the default being
5613 to buffer arbitrary chunks of data).
5614
Raymond Hettinger35631532009-01-09 03:58:09 +00005615- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5616 instead of ints (reducing its size from 4 to 8 times thereby reducing
5617 Python's overall memory).
5618
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005619- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5620 an existing .py counterpart, override the co_filename attributes of all
5621 code objects if the original filename is obsolete (which can happen if the
5622 file has been renamed, moved, or if it is accessed through different paths).
5623 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5624
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005625- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5626 one byte. Also fixes the meaning of len() so that it returns the number of
5627 items, rather than the size in bytes.
5628
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005629- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005631- Issue #4747: When the terminal does not use utf-8, executing a script with
5632 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5633
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005634- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5638 did not get collected.
5639
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005640- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5641 where the tp_hash and tp_dict slots are both NULL.
5642
Georg Brandlccc47b62008-12-28 11:44:14 +00005643- Issue #4759: None is now allowed as the first argument of
5644 bytearray.translate(). It was always allowed for bytes.translate().
5645
Skip Montanaro80072cb2008-12-23 03:51:14 +00005646- Added test case to ensure attempts to read from a file opened for writing
5647 fail.
5648
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005649- Issue #3106: Speedup some comparisons (str/str and int/int).

5653
Antoine Pitrou621601a2008-12-17 23:18:19 +00005654- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5656 unreachable. Original patch by Neil Schemenauer.
5657

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005660- Issue #2173: When getting device encoding, check that return value of
5661 nl_langinfo is not the empty string. This was causing silent build
5662 failures on OS X.
5663
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005664- Issue #4597: Fixed several opcodes that weren't always propagating
5665 exceptions.
5666
5667- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005668 context manager returns a value that cannot be converted to a bool.
5669
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005670- Issue #4445: Replace "sizeof(PyBytesObject)" with
5671 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5672 bytes instances. On a typical machine this saves 3 bytes of memory
5673 (on average) per allocation of a bytes instance.
5674
Christian Heimesa872de52008-12-05 08:26:55 +00005675- Issue #4533: File read operation was dreadfully slow due to a slowly
5676 growing read buffer. Fixed by using the same growth rate algorithm as
5677 Python 2.x.
5678
Antoine Pitrou5504e892008-12-06 21:27:53 +00005679- Issue #4509: Various issues surrounding resize of bytearray objects to
5680 which there are buffer exports (e.g. memoryview instances).
5681
Georg Brandlf9734072008-12-07 15:30:06 +00005682- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5683 method on file objects with closefd=False. The file descriptor is still
5684 kept open but the file object behaves like a closed file. The ``FileIO``
5685 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005687- Issue #4569: Interpreter crash when mutating a memoryview with an item size

5693
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005694- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5695 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5696 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5697 of using the replace error handler in PyUnicode_DecodeUTF8().
