Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +000013- Issue #3088: Corrected a race condition in classes derived from
14 threading.local: the first member set by a thread could be saved in
15 another thread's dictionary.
16
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +000017- Issue #3004: Minor change to slice.indices(): the start and stop
18 arguments are now treated identically, making the behaviour easier
19 to describe and understand. For example, slice(None, -10,
20 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
21 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
22 10, -1).

367
Ronald Oussoren5640ce22008-06-05 12:58:24 +0000368- On MacOS X it is now possible to install the framework in 64-bit
369 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +0000370 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +0000371
372 This is controlled by the configure argument ``--with-universal-archs``:
373
374 - ``--with-universal-archs=all``: install 4-way universal
375
376 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
377
378 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
379
380 This option should be used in combination with ``--enable-universalsdk=``.
381
382 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +0000432- Issue #1631171: Re-implement the 'warnings' module in C (the
433 original Python code has been kept as backup). This will allow for
434 using the 'warning's machinery in such places as the parser where
435 use of pure Python code is not possible. Both the ``showarning()``
436 and ``formatwarning()`` gain an optional 'line' argument which is
437 not called by default for backwards-compatibility reasons. Setting
438 ``warnings.showwarning()`` to an implementation that lacks support
439 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +0000502- Issue #2550: The approach used by client/server code for obtaining
503 ports to listen on in network-oriented tests has been refined in an
504 effort to facilitate running multiple instances of the entire
505 regression test suite in parallel without issue.
506 test_support.bind_port() has been fixed such that it will always
507 return a unique port -- which wasn't always the case with the
508 previous implementation, especially if socket options had been set
509 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
510 new implementation of bind_port() will actually raise an exception
511 if it is passed an AF_INET/SOCK_STREAM socket with either the
512 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
513 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
514 the socket it's been passed. This currently only applies to
515 Windows. This option prevents any other sockets from binding to the
516 host/port we've bound to, thus removing the possibility of the
517 'non-deterministic' behaviour, as Microsoft puts it, that occurs
518 when a second SOCK_STREAM socket binds and accepts to a host/port
519 that's already been bound by another socket. The optional preferred
520 port parameter to bind_port() has been removed. Under no
521 circumstances should tests be hard coding ports!
522
523 test_support.find_unused_port() has also been introduced, which will
524 pass a temporary socket object to bind_port() in order to obtain an
525 unused port. The temporary socket object is then closed and
526 deleted, and the port is returned. This method should only be used
527 for obtaining an unused port in order to pass to an external program
528 (i.e. the -accept [port] argument to openssl's s_server mode) or as
529 a parameter to a server-oriented class that doesn't give you direct
530 access to the underlying socket used.
531
532 Finally, test_support.HOST has been introduced, which should be used
533 for the host argument of any relevant socket calls (i.e. bind and
534 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +0000535
536 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +0000537 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +0000538 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
539 test_asynchat and test_socket_ssl.
540
Georg Brandl3ee81df2008-05-17 18:14:43 +0000541 It is now possible for multiple instances of the regression test
542 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +0000596- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +0000597 \Uxxxxxxxx did not accept values outside the Basic Multilingual
598 Plane. This affected raw unicode literals and the
599 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
600 this case, like normal unicode literals and the 'unicode-escape'
601 codec.

810
Fred Drakea8ee94b2008-03-01 02:45:07 +0000811- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000812 644. The mode is now inherited from the py file.

815
816- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +0000817
Vinay Sajipb7edfc42008-04-02 21:10:23 +0000818- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +0000819 issue 215555 for a discussion.
820
Eric Smitha73fbe72008-02-23 03:09:44 +0000821- Added the future_builtins module, which contains hex() and oct().
822 These are the PEP 3127 version of these functions, designed to be
823 compatible with the hex() and oct() builtins from Python 3.0. They
824 differ slightly in their output formats from the existing, unchanged
825 Python 2.6 builtins. The expected usage of the future_builtins
826 module is:
827 from future_builtins import hex, oct
828
Eric Smith7ef40bf2008-02-20 23:34:22 +0000829- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
830 exponents for exponents with absolute value < 100. Follows C99
831 standard. This is a change on Windows, which would use 3 digits.
832 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
833 so that any alterations it does to the resulting string will be
834 available in stringlib/formatter.h (for float.__format__).
835
Eric Smith5a3c1352008-02-19 13:21:56 +0000836- Implemented PEP 3101, Advanced String Formatting. This adds a new
837 builtin format(); a format() method for str and unicode; a
838 __format__() method to object, str, unicode, int, long, float, and
839 datetime; the class string.Formatter; and the C API
840 PyObject_Format().
841
Georg Brandl3ee81df2008-05-17 18:14:43 +0000842- Fixed several potential crashes, all caused by specially crafted

Vinay Sajipb7edfc42008-04-02 21:10:23 +0000846- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +0000847 prevent a possible crash: an Abstract Base Class would try to access
848 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000849

851 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +0000852
Georg Brandl3ee81df2008-05-17 18:14:43 +0000853- Clear all free lists during a gc.collect() of the highest generation
854 in order to allow pymalloc to free more arenas. Python may give back
855 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +0000856
Georg Brandl3ee81df2008-05-17 18:14:43 +0000857- Issue #2045: Fix an infinite recursion triggered when printing a
858 subclass of collections.defaultdict, if its default_factory is set
859 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +0000867- Patch #1953: Added ``sys._compact_freelists()`` and the C API
868 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000869 to compact the internal free lists of pre-allocted ints and floats.
870
Georg Brandl3ee81df2008-05-17 18:14:43 +0000871- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
872 calls. Python expected the return type int but the fork familie
873 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +0000874
Georg Brandl3ee81df2008-05-17 18:14:43 +0000875- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +0000887- Patch #1473257: generator objects gain a gi_code attribute. This is
888 the same object as the func_code attribute of the function that
889 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000890
Georg Brandl3ee81df2008-05-17 18:14:43 +0000891- Issue #1920: "while 0" statements were completely removed by the
892 compiler, even in the presence of an "else" clause, which is
893 supposed to be run when the condition is false. Now the compiler
894 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000895
Guido van Rossumeead05f2008-01-24 18:21:02 +0000896- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000900- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000901 suppressed while an extension is loaded by calling SetErrorMode in
902 dynload_win.c. The error is still reported properly.
903
Georg Brandl3ee81df2008-05-17 18:14:43 +0000904- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +0000905 several extension methods and modules do not work without unicode
906 support.
907
Georg Brandl26543b12008-01-21 18:36:51 +0000908- Issue #1882: when compiling code from a string, encoding cookies in the
909 second line of code were not always recognized correctly.
910
Georg Brandl14404b62008-01-19 19:27:05 +0000911- Issue #1679: "0x" was taken as a valid integer literal.
912
Georg Brandl6caad7d2008-01-26 14:19:22 +0000913- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000914 added.
915
Christian Heimesc94e2b52008-01-14 04:13:37 +0000916- sys.float_info / PyFloat_GetInfo: The floating point information
917 object was converted from a dict to a specialized structseq object.
918
Georg Brandl3ee81df2008-05-17 18:14:43 +0000919- Patch #1816: Added sys.flags structseq. It exposes the status of
920 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000921
Georg Brandl3ee81df2008-05-17 18:14:43 +0000922- Objects/structseq.c: Implemented new structseq representation. The
923 patch makes structseqs (e.g. the return value of os.stat) more
924 readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000925
Georg Brandl3ee81df2008-05-17 18:14:43 +0000926- Patch #1700288: added a type attribute cache that caches method
927 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000928
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000929- Bug #1776: __import__() no longer accepts filenames on any platform.
930 The first parameter to __import__() must be a valid module name.

933
Georg Brandl3ee81df2008-05-17 18:14:43 +0000934- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
935 envvar and sys.dont_write_bytecode attribute. All these can be set
936 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +0000937
Georg Brandl3ee81df2008-05-17 18:14:43 +0000938- Improve some exception messages when Windows fails to load an
939 extension module. Now we get for example '%1 is not a valid Win32
940 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000941

Georg Brandl3ee81df2008-05-17 18:14:43 +0000948 and INF. float("nan"), float("inf") and float("-inf") now work on
949 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +0000950
Georg Brandl3ee81df2008-05-17 18:14:43 +0000951- Compiler now generates simpler and faster code for dictionary
952 literals. The oparg for BUILD_MAP now indicates an estimated
953 dictionary size. There is a new opcode, STORE_MAP, for adding
954 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +0000983- Patch #1739468: Directories and zipfiles containing a __main__.py
984 file can now be directly executed by passing their name to the
985 interpreter. The directory/zipfile is automatically inserted as the
986 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +0000988- Issue #1265: Fix a problem with sys.settrace, if the tracing
989 function uses a generator expression when at the same time the
990 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000991
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000992- sets and frozensets now have an isdisjoint() method.

995
Neal Norwitz44f326e2007-10-05 05:29:17 +0000996- Fix warnings found by the new version of the Coverity checker.
997
Georg Brandl3ee81df2008-05-17 18:14:43 +0000998- The enumerate() builtin function is no longer bounded to sequences
999 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1000 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001001
Georg Brandl3ee81df2008-05-17 18:14:43 +00001002- Issue #1686386: Tuple's tp_repr did not take into account the
1003 possibility of having a self-referential tuple, which is possible
1004 from C code. Nor did object's tp_str consider that a type's tp_str
1005 could do something that could lead to an inifinite recursion.
1006 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1007 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001008
Georg Brandl3ee81df2008-05-17 18:14:43 +00001009- Issue #1164: It was possible to trigger deadlock when using the
1010 'print' statement to write to a file since the GIL was not released
1011 as needed. Now PyObject_Print() does the right thing along with
1012 various tp_print implementations of the built-in types and those in
1013 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001014
Georg Brandl3ee81df2008-05-17 18:14:43 +00001015- Issue #1147: Exceptions were directly allowing string exceptions in

1017 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001018
Georg Brandl3ee81df2008-05-17 18:14:43 +00001019- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00001021
Brett Cannon1e534b52007-09-07 04:18:30 +00001022- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001023 PyObject_Call() never calling back out to Python code to trigger
1024 recursion depth updates/checks. Required the creation of a static
1025 RuntimeError instance in case normalizing an exception put the
1026 recursion check value past its limit. Fixes crashers
1027 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00001028

Neal Norwitz0ac60192007-05-27 04:08:54 +00001042- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00001043 __*__ attributes. (Some already existed, e.g., __doc__ and
1044 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00001045
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00001046- Add -3 option to the interpreter to warn about features that are
1047 deprecated and will be changed/removed in Python 3.0.
1048
Georg Brandl2134e752007-05-21 20:34:16 +00001049- Patch #1686487: you can now pass any mapping after '**' in function
1050 calls.
1051
Collin Winter62903052007-05-18 23:11:24 +00001052- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00001053 "except E as target:". This is to provide forwards compatibility
1054 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00001056- Deprecate BaseException.message as per PEP 352.
1057
Georg Brandl3ee81df2008-05-17 18:14:43 +00001058- Issue #1303614: don't expose object's __dict__ when the dict is

1060
Vinay Sajip8549ce32007-05-06 17:53:37 +00001061- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00001062 setting a plain string, ie don't expand to single letter identifiers.
1063
Raymond Hettinger13936692007-04-11 18:40:58 +00001064- Request #1191699: Slices can now be pickled.
1065
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00001066- Request #1193128: str.translate() now allows a None argument for

1068 remaining characters.
1069
Georg Brandl5cb76c12007-03-21 09:00:39 +00001070- Patch #1682205: a TypeError while unpacking an iterable is no longer
1071 masked by a generic one with the message "unpack non-sequence".
1072
Neal Norwitzaa754b72007-03-21 06:39:48 +00001073- Remove unused file Python/fmod.c.
1074
Guido van Rossum143b5642007-03-23 04:58:42 +00001075- Bug #1683368: The object.__init__() and object.__new__() methods are
1076 now stricter in rejecting excess arguments. The only time when
1077 either allows excess arguments is when it is not overridden and the
1078 other one is. For backwards compatibility, when both are
1079 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00001080 warning later). Also, type.__init__() insists on the same signature
1081 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00001082
Georg Brandl3ee81df2008-05-17 18:14:43 +00001083- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
1084 object to complex using its __complex__() method before falling back
1085 to the __float__() method. Therefore, the functions in the cmath
1086 module now can operate on objects that define a __complex__()
1087 method.
Georg Brandl2b869942007-03-17 16:08:45 +00001088
Georg Brandl3ee81df2008-05-17 18:14:43 +00001089- Patch #1623563: allow __class__ assignment for classes with

Georg Brandl3ee81df2008-05-17 18:14:43 +00002161 time so that opening a database previously created with the DB_DUP
2162 or DB_DUPSORT flag set will keep the proper behavior on subsequent
2163 opens. Specifically: dictionary assignment to a DB object will
2164 replace all values for a given key when the database allows
2165 duplicate values. DB users should use DB.put(k, v) when they want
2166 to store duplicates; not DB[k] = v.

2173 characters with ASCII value less than 32. Also, it correctly quotes
2174 dots only if they occur on a single line, as opposed to the previous
2175 behavior of quoting dots if they are the second character of any
2176 line.
