500 The coupling between the two Python instances often caused confusion and, as
501 of macOS 10.12, changes to the site-packages layout can cause pip component
502 installations to fail. This change reverts the effects introduced in 2.7.0
503 by Issue #4865. If you are using a package with both the Apple system Python
504 2.7 and a user-installed Python 2.7, you will need to ensure that copies of
505 the package are installed with both Python instances.

942 compile() are passed buffer objects. These objects are not necessarily
943 terminated by a null byte, but the functions assumed they were.
944
Serhiy Storchaka5d7d26c2015-11-14 15:14:29 +0200945- Issue #25388: Fixed tokenizer hang when processing undecodable source code

Victor Stinnera87633e2015-10-01 09:57:26 +0200959- Issue #25003: os.urandom() doesn't use getentropy() on Solaris because
960 getentropy() is blocking, whereas os.urandom() should not block. getentropy()
961 is supported since Solaris 11.3.

975 PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains()
976 to check for and handle errors correctly.
977
Benjamin Peterson2c992a02015-05-28 12:45:31 -0500978- Issue #4753: On compilers where it is supported, use "computed gotos" for
979 bytecode dispatch in the interpreter. This improves interpretation

1052 called directly instead of calling the encode() method of the string.
1053

Martin Panter0d84ea72016-05-22 03:11:44 +00001161- Issue #15348: Stop the debugger engine (normally in a user process)
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -05001162 before closing the debugger window (running in the IDLE process).
1163 This prevents the RuntimeErrors that were being caught and ignored.
1164
1165- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
1166 debugger is active (15347); b) closing the debugger with the [X] button
1167 (15348); and c) activating the debugger when already active (24455).
1168 The patch by Mark Roseman does this by making two changes.
1169 1. Suspend and resume the gui.interaction method with the tcl vwait
1170 mechanism intended for this purpose (instead of root.mainloop & .quit).
1171 2. In gui.run, allow any existing interaction to terminate first.
1172
1173- Change 'The program' to 'Your program' in an IDLE 'kill program?' message

Terry Jan Reedy1b6333a2015-10-04 01:14:45 -04001191- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
1192 It is more or less IDLE Classic inverted, with a cobalt blue background.
1193 Strings, comments, keywords, ... are still green, red, orange, ... .
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -05001194 To use it with IDLEs released before November 2015, hit the
1195 'Save as New Custom Theme' button and enter a new name,
1196 such as 'Custom Dark'. The custom theme will work with any IDLE
1197 release, and can be modified.

2637
2638- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
2639 and later systems as is currently done for Python 3.x installers.
2640 For 2.7.7 only, we will provide three installers:
2641 the legacy deprecated 10.3+ 32-bit-only format;
2642 the newer 10.5+ 32-bit-only format;
2643 and the unchanged 10.6+ 64-/32-bit format.
2644 Although binary installers will no longer be available from
2645 python.org as of 2.7.8, it will still be possible to build from
2646 source on 10.3.9 and 10.4 systems if necessary.
2647 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08004027- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
4028 In particular, fix extension module build failures when trying to use
4029 32-bit-only installer Pythons on systems with Xcode 4 (currently
4030 OS X 10.8, 10.7, and optionally 10.6).
4031 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
4032 * Since Xcode 4 removes ppc support, extension module builds now
4033 check for ppc compiler support and by default remove ppc and
4034 ppc64 archs when they are not available.
4035 * Extension module builds now revert to using system installed
4036 headers and libs (/usr and /System/Library) if the SDK used
4037 to build the interpreter is not installed or has moved.
4038 * Try to avoid building extension modules with deprecated
4039 and problematic Apple llvm-gcc compiler. If original compiler
4040 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01004477- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01004478 has left two versions of customize_compiler, the original in
4479 distutils.sysconfig and another copy in distutils.ccompiler, with some
4480 parts of distutils calling one and others using the other.

Ned Deily0d0ea482012-02-10 12:59:06 +01004484- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
4485 Distutils-based packages with C extension modules may fail because
4486 Apple has removed gcc-4.2, the version used to build python.org
4487 64-bit/32-bit Pythons. If the user does not explicitly override
4488 the default C compiler by setting the CC environment variable,
4489 Distutils will now attempt to compile extension modules with clang
4490 if gcc-4.2 is required but not found. Also as a convenience, if
4491 the user does explicitly set CC, substitute its value as the default
4492 compiler in the Distutils LDSHARED configuration variable for OS X.
4493 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
4494 SDK, neither of which are available in Xcode 4. This change does not
4495 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07004745- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
4746 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
4747 interpreter process. This could cause failures in non-Distutils subprocesses
4748 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02004749 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07004750 deployment target only in the environment of each build subprocess. It is
4751 still possible to globally override the default by setting
4752 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
4753 greater or equal to the default value, the value with which the interpreter
4754 was built.

4784 the ticker doesn't have to wind down to zero from the old starting point
4785 before the new interval takes effect. And if the user increases the
4786 interval, it makes sure the new limit takes effect right away rather have an
4787 early task switch before recognizing the new interval.

5630 long for a class whose __long__ method returns a plain int. This
5631 fixes an interpreter crash when initializing an instance of a long

Raymond Hettinger20397532010-09-12 02:11:45 +00005784- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
5785 This prevents user-created self-referencing ordered dictionaries from
5786 becoming permanently uncollectable GC garbage. The downside is that
5787 removing __del__ means that the internal doubly-linked list has to wait for
5788 GC collection rather than freeing memory immediately when the refcnt drops
5789 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00006247- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
6248 start byte and the continuation byte(s) are now considered invalid, instead
6249 of the number of bytes specified by the start byte.
6250 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
6251 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
6252 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
6253 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00006261- Issue #8748: Fix two issues with comparisons between complex and integer
6262 objects. (1) The comparison could incorrectly return True in some cases
6263 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
6264 (2) The comparison raised an OverflowError for large integers, leading
6265 to unpredictable exceptions when combining integers and complex objects
6266 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00006268- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00006405- Issue #1533: Fix inconsistency in range function argument processing: any
6406 non-float non-integer argument is now converted to an integer (if possible)
6407 using its __int__ method. Previously, only small arguments were treated this
6408 way; larger arguments (those whose __int__ was outside the range of a C long)
6409 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00006417 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00006418 benefit compared to the dynamic memory allocation fallback. Patch by
6419 Charles-François Natali.

6444 messages when accessing undefined class attributes because of the cheap
6445 inheritance with the underlying socket object. The cheap inheritance has been
6446 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00006447

Georg Brandlfee0f442010-05-22 21:26:21 +00006459- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6460 operation raises multiple signals and more than one of those signals is
6461 trapped, the specification determines the order in which the signals should be
6462 handled. In many cases this order wasn't being followed, leading to the wrong
6463 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00006464

6631-----------------
6632
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00006633- Issue #7301: Add environment variable $PYTHONWARNINGS.
6634
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00006635- Issue #8329: Don't return the same lists from select.select when no fds are
6636 changed.
6637
Georg Brandlfee0f442010-05-22 21:26:21 +00006638- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00006639 on 64-bit machines. The shift count for either left or right shift is
6640 permitted to be up to sys.maxsize.
6641
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00006642- Ensure that tokenization of identifiers is not affected by locale.
6643
Georg Brandlfee0f442010-05-22 21:26:21 +00006644- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00006645
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00006646- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
6647
Georg Brandlfee0f442010-05-22 21:26:21 +00006648- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
6649 with a non-empty format string. This is an effort to future-proof user
6650 code. If a derived class does not currently implement __format__ but later
6651 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00006652 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00006653 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00006654
Antoine Pitroua57df2c2010-03-31 21:32:15 +00006655- Issue #8268: Old-style classes (not just instances) now support weak
6656 references.
6657
Georg Brandlfee0f442010-05-22 21:26:21 +00006658- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
6659 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00006660
Martin Panter6a8163a2016-04-15 02:14:19 +00006661- Issue #1583863: A unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00006662
Benjamin Peterson96545892010-03-21 20:21:00 +00006663- Issue #6474: Make error message from passing an inadequate number of keyword
6664 arguments to a function correct.
6665
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00006666- Issue #8164: Don't allow lambda functions to have a docstring.
6667
Victor Stinner66644262010-03-10 22:30:19 +00006668- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00006669 (SIGINT). If an error occurs while importing the site module, the error is
6670 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00006671 module.
6672
Collin Winter001a3952010-03-18 21:54:01 +00006673- Code objects now support weak references.

6676-------
6677
R. David Murray661303f2010-04-13 20:57:40 +00006678- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
6679
Antoine Pitrouf9de5342010-04-05 21:35:07 +00006680- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00006681 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
6682 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00006683
Benjamin Peterson76a23c12010-04-04 23:23:22 +00006684- Issue #8310: Allow dis to examine new style classes.
6685
Georg Brandlfee0f442010-05-22 21:26:21 +00006686- Issue #8257: The Decimal construct now accepts a float instance directly,
6687 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00006688
6689 >>> Decimal(1.1)
6690 Decimal('1.100000000000000088817841970012523233890533447265625')
6691
Raymond Hettinger34c35b22010-04-03 10:22:00 +00006692- collections.Counter() now supports a subtract() method.
6693
Georg Brandlfee0f442010-05-22 21:26:21 +00006694- The functools module now has a total_ordering() class decorator to simplify
6695 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00006696
Georg Brandlfee0f442010-05-22 21:26:21 +00006697- The functools module also adds cmp_to_key() as a tool to transition old-style
6698 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00006699
Georg Brandlfee0f442010-05-22 21:26:21 +00006700- Issue #8294: The Fraction constructor now accepts Decimal and float instances
6701 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00006702
Georg Brandlfee0f442010-05-22 21:26:21 +00006703- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6704 InvalidOperation instead of returning False. (Comparisons involving a quiet
6705 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6706 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00006707
Georg Brandlfee0f442010-05-22 21:26:21 +00006708- Issue #2531: Comparison operations between floats and Decimal instances now
6709 return a result based on the numeric values of the operands; previously they
6710 returned an arbitrary result based on the relative ordering of id(float) and
6711 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00006712
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00006713- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00006714 argument `-` which tells it to read files to compile from stdin. Each line is
6715 read on demand and the named file is compiled immediately. (Original patch by
6716 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00006717
Georg Brandlfee0f442010-05-22 21:26:21 +00006718- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
6719 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00006721- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
6722 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00006723 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00006724
Georg Brandlfee0f442010-05-22 21:26:21 +00006725- Comparisons using one of <, <=, >, >= between a complex instance and a
6726 Fractions instance now raise TypeError instead of returning True/False. This
6727 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6728 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00006729

6738
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00006739- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00006740 didn't support chflags() (for example ZFS under FreeBSD). The error is now
6741 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00006742
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00006743- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
6744 deprecated.
6745
Georg Brandlfee0f442010-05-22 21:26:21 +00006746- Issue #7860: platform.uname now reports the correct 'machine' type when Python
6747 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00006748

6753 existing at the same time, causing a Unicode error when configuration code
6754 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00006755

Antoine Pitroueee91cd2010-03-26 19:27:16 +00006759- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
6760 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
6761 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00006780- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00006781 for ``TimedRotatingFileHandler`` by using the modification time of an existing
6782 log file to compute the next rollover time. If the log file does not exist,
6783 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00006784
Georg Brandlba83f822010-03-14 09:50:54 +00006785- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00006793- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
6794 a base64 transfer-encoded payload *after* decoding it; it no longer does.
6795 This is a behavior change, so email's minor version number is now bumped, to
6796 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00006824- Issue #8300: When passing a non-integer argument to struct.pack with any
6825 integer format code, struct.pack first attempts to convert the non-integer
6826 using its __index__ method. If that method is non-existent or raises

Georg Brandlba83f822010-03-14 09:50:54 +00006829- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
6830 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
6831 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00006832 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
6833 inconsistent: __int__ was used for some integer codes but not for others, and
6834 the set of integer codes for which it was used differed between native packing
6835 and standard packing.)

7240-----------------
7241
Georg Brandlba83f822010-03-14 09:50:54 +00007242- The ``__complex__()`` method is now looked up on the class of instances to
7243 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00007245- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

7247
Mark Dickinson1b34d252010-01-01 17:27:30 +00007248- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00007249 DeprecationWarning when passed a float argument where an integer was expected.
7250 These functions and methods now raise TypeError instead. The majority of the
7251 effects of this change are in the extension modules, but some core functions
7252 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
7253 and many unicode/str methods.

7264 used to drop the time part of the result.
7265
Georg Brandlba83f822010-03-14 09:50:54 +00007266- Issue #1811: Improve accuracy and cross-platform consistency for true division
7267 of integers: the result of a/b is now correctly rounded for ints a and b (at
7268 least on IEEE 754 platforms), and in particular does not depend on the
7269 internal representation of a long.

7277
Georg Brandlba83f822010-03-14 09:50:54 +00007278 These executables now work properly with the arch(1) command: ``arch -ppc
7279 python`` will start a universal binary version of python in PPC mode (unlike
7280 previous releases).

7419 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00007420
Georg Brandlba83f822010-03-14 09:50:54 +00007421- Remove switch from "%f" formatting to "%g" formatting for floats larger than
7422 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00007423

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00007434
Georg Brandlba83f822010-03-14 09:50:54 +00007435- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
7436 decimal string that's guaranteed to round back to x under correct rounding
7437 (with round-half-to-even rounding mode). Previously it gave a string based on
7438 rounding x to 17 decimal digits. repr(x) for a complex number behaves
7439 similarly. On platforms where the correctly-rounded strtod and dtoa code is
7440 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007441
Georg Brandlba83f822010-03-14 09:50:54 +00007442- Issue #7117: On almost all platforms: float-to-string and string-to-float
7443 conversions within Python are now correctly rounded. Places these conversions
7444 occur include: str for floats and complex numbers; the float and complex
7445 constructors; old-style and new-style numeric formatting; serialization and
7446 deserialization of floats and complex numbers using marshal, pickle and json;
7447 parsing of float and imaginary literals in Python code; Decimal-to-float
7448 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007449
Georg Brandlba83f822010-03-14 09:50:54 +00007450 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
7451 providing correctly-rounded strtod and dtoa C functions. This code is
7452 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
7453 the C compiler. There may be a small number of platforms on which correct
7454 operation of this code cannot be guaranteed, so the code is not used: notably,
7455 this applies to platforms where the C double format is not IEEE 754 binary64,
7456 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
7457 and Python's configure script is unable to determine how to change the FPU
7458 precision. On these platforms conversions use the platform strtod and dtoa,
7459 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00007461- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
7462 uses the correctly-rounded string <-> float conversions described above (when
7463 available), and so produces correctly rounded results that will display nicely
7464 under the float repr. There are two related small changes: (1) round now
7465 accepts any class with an ``__index__()`` method for its second argument (but
7466 no longer accepts floats for the second argument), and (2) an excessively
7467 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
7468 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00007611 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
7612 (2) parsing of strings representing infinities and nans was locale aware; and
7613 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00007615- Issue #5920: For ``float.__format__()``, change the behavior with the empty
7616 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
7617 but with at least one decimal point and with a default precision
7618 of 12. Previously, the behavior the same but with a default precision of 6.
7619 This more closely matches ``str()``, and reduces surprises when adding
7620 alignment flags to the empty presentation type. This also affects the new
7621 complex.__format__ in the same way.
7622
7623- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
7624 classtype's, even if it was None. property now inserts the __doc__ into the

7695 internal representation of integers, for performance reasons. Base 2**30 is
7696 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00007804- Issue #4445: Replace ``sizeof(PyStringObject)`` with
7805 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
7806 instances. On a typical machine this saves 3 bytes of memory (on average) per
7807 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00007809- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Georg Brandlba83f822010-03-14 09:50:54 +00007813- Issue #3689: The list reversed iterator now supports __length_hint__ instead

7818
Georg Brandlba83f822010-03-14 09:50:54 +00007819- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
7820 file objects with closefd=False. The file descriptor is still kept open but
7821 the file object behaves like a closed file. The ``FileIO`` object also got a
7822 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00007842- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00007845- On windows, ``os.chdir()`` given unicode was not working if
7846 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
7847 this code path is really executed because I cannot move to such directory on
7848 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007850- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7851 element is temporarily replaced with an equivalent frozenset. But the
7852 eventual KeyError would always report the empty ``frozenset()`` as the missing
7853 key. Now it correctly refers to the initial element.

7872
Walter Dörwalded960ac2009-05-03 22:36:33 +00007873- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
7874 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7875 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7876 of using the replace error handler in PyUnicode_DecodeUTF8().
7877
Walter Dörwald726ba8e2009-05-06 14:32:35 +00007878- Issue #3739: The unicode-internal encoder now reports the number of characters

7880
Georg Brandlba83f822010-03-14 09:50:54 +00007881- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
7882 allocator will be automatically disabled when running under Valgrind. This
7883 gives improved memory leak detection when running under Valgrind, while taking
7884 advantage of pymalloc at other times.

9274
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00009275- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
9276 PyString_FromFormat or PyErr_Format to display size_t values. The macro
9277 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
9278 ``printf`` function, whereas PyString_FromFormat has an independent
9279 implementation and uses "%zd" on all platforms for size_t values.
9280 This makes a difference on win64, where ``printf`` needs "%Id" to display
9281 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00009283- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

9287 object; previously an int would be returned for small values. the __long__
9288 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00009298 was correctly parsed but parsing of subsequent arguments failed.
9299
Vinay Sajip35e3b032008-09-01 14:33:59 +00009300- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00009301 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
9302 mechanism. In the process, fix a bug where isinstance() and issubclass(),
9303 when given a tuple of classes as second argument, were looking up
9304 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
9305 type object.
9306

9449Core and Builtins
9450-----------------
9451
Guido van Rossumf8402962008-08-20 15:01:50 +00009452- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
9453 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
9454 extensions do not automatically benefit from the class attribute
9455 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
9456 to their tp_flags field if they care. This is a backwards
9457 compatibility feature; in 3.0, all types will use the cache by
9458 default.
9459
Benjamin Petersonf647dc12008-08-20 01:27:30 +00009460- Keyword arguments can now follow starred arguments. (``f(a, *args,
9461 keyword=23)`` is now valid syntax.)
9462
Thomas Heller0ad5ae02008-08-19 19:25:04 +00009463- ctypes function pointers that are COM methods have a boolean True
9464 value again.
9465
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00009466- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
9467 by denying s# to parse objects that have a releasebuffer procedure,
9468 and introducing s*.
9469
Georg Brandl1e13ea92008-08-11 09:07:59 +00009470- Issue #3537: Fix an assertion failure when an empty but presized dict
9471 object was stored in the freelist.
9472
Mark Dickinsonb6467572008-08-04 21:30:09 +00009473- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
9474 ValueError consistently across platforms.
9475
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00009476- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
9477 (64bit Unix, for example), unichr() would truncate its argument and return
9478 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
9479
Neal Norwitze7d8be82008-07-31 17:17:14 +00009480- Apply security patches from Apple.
9481
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00009482- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
9483 PyErr_ExceptionMatches returns 0 when an exception occurs there.
9484
Antoine Pitrou92f82162008-07-25 22:22:08 +00009485- Issue #1819: function calls with several named parameters are now on
9486 average 35% faster (as measured by pybench).
9487
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00009488- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
9489 the python debugger steps into a class statement: the free variables (local
9490 variables defined in an outer scope) would be deleted from the outer scope.
9491
Gregory P. Smith0470bab2008-07-22 04:46:32 +00009492- Issue #2620: Overflow checking when allocating or reallocating memory
9493 was not always being done properly in some python types and extension
9494 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
9495 all been updated to perform better checks and places in the code that
9496 would previously leak memory on the error path when such an allocation
9497 failed have been fixed.
9498

9500-------
9501
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00009502- Issue #3612: Added some missing basic types in ctypes.wintypes.
9503
Benjamin Petersone977ad42008-08-20 01:42:01 +00009504- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
9505 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
9506
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00009507- Issue #2234: distutils failed for some versions of the cygwin compiler. The
9508 version reported by these tools does not necessarily follow the python
9509 version numbering scheme, so the module is less strict when parsing it.
9510
Nick Coghlanf70385a2008-08-18 12:42:46 +00009511- Issue #2235: Added Py3k warnings for types which will become unhashable
9512 under the stricter __hash__ inheritance rules in 3.0. Several types
9513 which did not meet the rules for hash invariants and were already
9514 unhashable in 3.0 have now been explicitly flagged as unhashable in
9515 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
9516 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
9517
Brett Cannon88f801d2008-08-18 00:46:22 +00009518- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
9519 imported into the module but exposed as part of the module's API.
9520
Brett Cannon7b96f072008-08-18 00:41:11 +00009521- Remove an unneeded import of abc.ABCMeta from 'inspect'.
9522
Brett Cannon46225e72008-08-18 00:36:52 +00009523- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
9524
Brett Cannon25c9d6a2008-08-17 22:10:11 +00009525- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
9526
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00009527- Issue #3575: Incremental decoder's decode function now takes bytearray
9528 by using 's*' instead of 't#'.
9529
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00009530- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00009531 fails unicode conversion on 2nd parameter. (windows only)
9532
Georg Brandl222e2082010-08-01 22:27:39 +00009533- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00009534 in a redirect.
9535
Brett Cannonabe423e2008-08-16 21:47:07 +00009536- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00009537 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00009538
Martin Panter6a8163a2016-04-15 02:14:19 +00009539- Issue #2776: fixed small issue when handling a URL with double slash
Facundo Batistaeb90b782008-08-16 14:44:07 +00009540 after a 302 response in the case of not going through a proxy.
9541
Antoine Pitroub90a8be2008-08-15 21:03:21 +00009542- Issue #2676: in the email package, content-type parsing was hanging on
9543 pathological input because of quadratic or exponential behaviour of a
9544 regular expression.
9545
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00009546- Issue #3476: binary buffered reading through the new "io" library is now
9547 thread-safe.
9548
Brett Cannonbf3157b2008-08-14 05:00:03 +00009549- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
9550 since mimetools itself is deprecated. Because modules are cached, all
9551 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
9552
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00009553- Issue #3134: shutil referenced undefined WindowsError symbol.
9554
Robert Schuppenies14646332008-08-10 11:01:53 +00009555- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
9556 menu entries were not deleted.
9557
Brett Cannon83e81842008-08-09 23:30:55 +00009558- Copied the implementation of reduce() to _functools.reduce() to have a
9559 version that did not raise a DeprecationWarning under -3.
9560
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00009561- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
9562 a MemoryError rather than silently stop the iteration.
9563
Guido van Rossum59ce9012008-08-09 14:55:34 +00009564- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
9565 to _sre.compile() will now be rejected. This should not affect anybody
9566 since the re.compile() function never generates invalid re-bytecode.
9567
Skip Montanaroa032bf42008-08-08 22:52:51 +00009568- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
9569 upon first access it can be automatically initialized from the csv file if
9570 it wasn't initialized during instantiation.
9571
Brett Cannon3aa2a492008-08-06 22:28:09 +00009572- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
9573 the reload() built-in has been removed.
9574
Brett Cannon7e30b672008-08-04 21:52:25 +00009575- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00009576 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

9578 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
9579 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
9580 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
9581 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00009582
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00009583- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
9584 raised an AttributeError.
9585
Benjamin Peterson01a24322008-07-28 23:35:27 +00009586- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00009587 asking for a specific length. This problem only affected files opened
9588 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00009589
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00009590- Issue #3449: Update decimal module to use most recent specification
9591 (v. 1.68) and tests (v. 2.58) from IBM.
9592
Georg Brandl222e2082010-08-01 22:27:39 +00009593- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00009594
Serhiy Storchaka16870742015-08-09 13:07:06 +03009595- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00009596 on a closed shelf.
9597
Georg Brandlf9efabb2008-07-23 15:16:45 +00009598- Deprecate the "ast" parser function aliases.
9599
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009600- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
9601
9602- Issue #3303: Fix a crash in locale.strcoll() when calling it with
9603 invalid arguments.
9604
9605- Issue #3302: Fix several crashes when calling locale's gettext functions
9606 with None arguments.
9607
9608- Issue #3389: Allow resolving dotted names for handlers in logging
9609 configuration files.
9610
9611- Deprecate the sunaudio module for removal in Python 3.0.
9612
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00009613- Issue #3394: zipfile.writestr sets external attributes when passed a
9614 file name rather than a ZipInfo instance, so files are extracted with
9615 mode 0600 rather than 000 under Unix.
9616
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00009617- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
9618 argument in python 2.5, this broke code that subclassed Popen to include its
9619 own poll method. Fixed my moving _deadstate to an _internal_poll method.

9628
Nick Coghlan6e8fef02008-08-18 13:14:22 +00009629- Issue #2235: the C API function PyObject_HashNotImplemented and its
9630 interaction with the tp_hash slot (added in 2.6b2) are now documented
9631
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00009632- Issue #643841: The language reference now provides more detailed
9633 coverage of the lookup process for special methods. The disclaimers
9634 regarding lack of coverage of new-style classes have also been
9635 removed, since the coverage is now fairly reasonable.

9640
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009641*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00009643Core and Builtins
9644-----------------
9645
Georg Brandl3e483f62008-07-16 22:57:41 +00009646- Issue #3156: Fix inconsistent behavior of the bytearray type: all
9647 its methods now allow for items objects that can be converted to
9648 an integer using operator.index().
9649
Mark Dickinson64b7e502008-07-16 09:40:03 +00009650- Issue #3360: Fix incorrect parsing of '020000000000.0', which
9651 produced a ValueError instead of giving the correct float.
9652
Eric Smitha5fa5a22008-07-16 00:11:49 +00009653- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
9654 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
9655
Mark Dickinson7103aa42008-07-15 19:08:33 +00009656- Issue #3008: the float type has a new instance method 'float.hex'
9657 and a new class method 'float.fromhex' to convert floating-point
9658 numbers to and from hexadecimal strings, respectively.
9659
Nick Coghlan6d6bd442008-07-15 15:40:22 +00009660- Issue #2235: __hash__ is once again inherited by default. To allow
9661 collections.Hashable to remain meaningful in the presence of the
9662 default hash implementation (object.__hash__), it is now possible
9663 to explicit block inheritance of hash by setting __hash__=None at
9664 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
9665 level.
9666
Nick Coghlanb028f502008-07-13 14:52:36 +00009667- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
9668 the parent module cannot be found while performing an absolute import.
9669 This means that an incorrectly defined __package__ attribute will
9670 now only prevent relative imports in that module rather than causing
9671 all imports from that module to fail.
9672
Nick Coghlan14ff9942008-07-08 14:21:42 +00009673- Issue #2517: Allow unicode messages in Exceptions again by correctly
9674 bypassing the instance dictionary when looking up __unicode__ on
9675 new-style classes.
9676
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00009677- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
9678 set to a custom object whose write() method happens to install
9679 another file in sys.stdout.
9680
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00009681- Issue #3088: Corrected a race condition in classes derived from
9682 threading.local: the first member set by a thread could be saved in
9683 another thread's dictionary.
9684
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00009685- Issue #3004: Minor change to slice.indices(): the start and stop
9686 arguments are now treated identically, making the behaviour easier
9687 to describe and understand. For example, slice(None, -10,
9688 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
9689 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
9690 10, -1).
9691
Georg Brandl278fc502008-07-19 12:46:12 +00009692- Issue #3219: Calling a function with repeated keyword arguments,
9693 f(a=2, a=23), would not cause a syntax error. This was a regression
9694 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00009695
Georg Brandl278fc502008-07-19 12:46:12 +00009696- Issue #2862: Make int and float freelist management consistent with
9697 other freelists. Changes their CompactFreeList apis into
9698 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00009703- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
9704 api functions without holding the GIL, which could lead to a fatal
9705 error when they failed.
9706
Martin v. Löwisaabf4042008-08-02 07:20:25 +00009707- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Thomas Heller880f5292008-07-15 19:39:38 +00009720- Issue #3313: Fixed a crash when a failed dlopen() call does not set
9721 a valid dlerror() message.

Thomas Heller2bad6572008-07-15 17:19:50 +00009723- Issue #3258: Fixed a crash when a ctypes POINTER type to an
9724 incomplete structure was created.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00009728- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
9729
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00009730- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00009731

Georg Brandl5cc774e2008-06-11 20:28:06 +000010141 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +000010142
10143 This is controlled by the configure argument ``--with-universal-archs``:
10144
10145 - ``--with-universal-archs=all``: install 4-way universal
10146
10147 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
10148
10149 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
10150
10151 This option should be used in combination with ``--enable-universalsdk=``.
10152
10153 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 +000010202- Issue #1631171: Re-implement the 'warnings' module in C (the
10203 original Python code has been kept as backup). This will allow for
10204 using the 'warning's machinery in such places as the parser where
10205 use of pure Python code is not possible. Both the ``showarning()``
10206 and ``formatwarning()`` gain an optional 'line' argument which is
10207 not called by default for backwards-compatibility reasons. Setting
10208 ``warnings.showwarning()`` to an implementation that lacks support
10209 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +000010232 reference to themselves.
10233
Gregory P. Smithd59fefb2008-04-22 08:11:33 +000010234- The getpass module has been improved on Unix. It now uses /dev/tty
10235 by default and uses stderr instead of stdout. A GetPassWarning is
10236 issued when input echo cannot be controlled.

10249 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +000010250
Georg Brandl3ee81df2008-05-17 18:14:43 +000010251- Issue #2513: distutils on Windows is now capable of cross-compiling

Georg Brandl3ee81df2008-05-17 18:14:43 +000010272- Issue #2550: The approach used by client/server code for obtaining
10273 ports to listen on in network-oriented tests has been refined in an
10274 effort to facilitate running multiple instances of the entire
10275 regression test suite in parallel without issue.
10276 test_support.bind_port() has been fixed such that it will always
10277 return a unique port -- which wasn't always the case with the
10278 previous implementation, especially if socket options had been set
10279 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
10280 new implementation of bind_port() will actually raise an exception
10281 if it is passed an AF_INET/SOCK_STREAM socket with either the
10282 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
10283 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
10284 the socket it's been passed. This currently only applies to
10285 Windows. This option prevents any other sockets from binding to the
10286 host/port we've bound to, thus removing the possibility of the
10287 'non-deterministic' behaviour, as Microsoft puts it, that occurs
10288 when a second SOCK_STREAM socket binds and accepts to a host/port
10289 that's already been bound by another socket. The optional preferred
10290 port parameter to bind_port() has been removed. Under no
10291 circumstances should tests be hard coding ports!
10292
10293 test_support.find_unused_port() has also been introduced, which will
10294 pass a temporary socket object to bind_port() in order to obtain an
10295 unused port. The temporary socket object is then closed and
10296 deleted, and the port is returned. This method should only be used
10297 for obtaining an unused port in order to pass to an external program
10298 (i.e. the -accept [port] argument to openssl's s_server mode) or as
10299 a parameter to a server-oriented class that doesn't give you direct
10300 access to the underlying socket used.
10301
10302 Finally, test_support.HOST has been introduced, which should be used
10303 for the host argument of any relevant socket calls (i.e. bind and
10304 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +000010305
10306 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +000010307 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +000010308 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
10309 test_asynchat and test_socket_ssl.
10310
Georg Brandl3ee81df2008-05-17 18:14:43 +000010311 It is now possible for multiple instances of the regression test
10312 suite to run in parallel without issue.

10580
Fred Drakea8ee94b2008-03-01 02:45:07 +000010581- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +000010582 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +000010590
Eric Smitha73fbe72008-02-23 03:09:44 +000010591- Added the future_builtins module, which contains hex() and oct().
10592 These are the PEP 3127 version of these functions, designed to be
10593 compatible with the hex() and oct() builtins from Python 3.0. They
10594 differ slightly in their output formats from the existing, unchanged
10595 Python 2.6 builtins. The expected usage of the future_builtins
10596 module is:
10597 from future_builtins import hex, oct
10598
Martin Pantera850ef62016-07-28 01:11:04 +000010599- Issue #1600: Modified PyOS_ascii_formatd to use at most 2 digit
Eric Smith7ef40bf2008-02-20 23:34:22 +000010600 exponents for exponents with absolute value < 100. Follows C99
10601 standard. This is a change on Windows, which would use 3 digits.
10602 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
10603 so that any alterations it does to the resulting string will be
10604 available in stringlib/formatter.h (for float.__format__).
10605
Eric Smith5a3c1352008-02-19 13:21:56 +000010606- Implemented PEP 3101, Advanced String Formatting. This adds a new
10607 builtin format(); a format() method for str and unicode; a
10608 __format__() method to object, str, unicode, int, long, float, and
10609 datetime; the class string.Formatter; and the C API
10610 PyObject_Format().
10611
Georg Brandl3ee81df2008-05-17 18:14:43 +000010612- Fixed several potential crashes, all caused by specially crafted
10613 __del__ methods exploiting objects in temporarily inconsistent
10614 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000010615
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010616- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +000010617 prevent a possible crash: an Abstract Base Class would try to access
10618 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000010619
Georg Brandl3ee81df2008-05-17 18:14:43 +000010620- Fixed repr() and str() of complex numbers with infinity or nan as
10621 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +000010622
Georg Brandl3ee81df2008-05-17 18:14:43 +000010623- Clear all free lists during a gc.collect() of the highest generation
10624 in order to allow pymalloc to free more arenas. Python may give back
10625 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +000010626
Georg Brandl3ee81df2008-05-17 18:14:43 +000010627- Issue #2045: Fix an infinite recursion triggered when printing a
10628 subclass of collections.defaultdict, if its default_factory is set
10629 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000010630
Christian Heimesf75dbef2008-02-08 00:11:31 +000010631- Fixed a minor memory leak in dictobject.c. The content of the free
10632 list was not freed on interpreter shutdown.
10633
Georg Brandl21e99f42010-03-07 15:23:59 +000010634- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +000010635 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +000010636
Georg Brandl3ee81df2008-05-17 18:14:43 +000010637- Patch #1953: Added ``sys._compact_freelists()`` and the C API
10638 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000010639 to compact the internal free lists of pre-allocted ints and floats.
10640
Georg Brandl3ee81df2008-05-17 18:14:43 +000010641- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
10642 calls. Python expected the return type int but the fork familie
10643 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +000010644
Georg Brandl3ee81df2008-05-17 18:14:43 +000010645- Issue #1678380: Fix a bug that identifies 0j and -0j when they
10646 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010654- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
10655 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +000010656
Georg Brandl3ee81df2008-05-17 18:14:43 +000010657- Patch #1473257: generator objects gain a gi_code attribute. This is
10658 the same object as the func_code attribute of the function that
10659 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +000010660
Georg Brandl3ee81df2008-05-17 18:14:43 +000010661- Issue #1920: "while 0" statements were completely removed by the
10662 compiler, even in the presence of an "else" clause, which is
10663 supposed to be run when the condition is false. Now the compiler
10664 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000010665
Guido van Rossumeead05f2008-01-24 18:21:02 +000010666- A few crashers fixed: weakref_in_del.py (issue #1377858);
10667 loosing_dict_ref.py (issue #1303614, test67.py);
10668 borrowed_ref_[34].py (not in tracker).
10669
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000010670- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000010671 suppressed while an extension is loaded by calling SetErrorMode in
10672 dynload_win.c. The error is still reported properly.
10673
Georg Brandl3ee81df2008-05-17 18:14:43 +000010674- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +000010675 several extension methods and modules do not work without unicode
10676 support.
10677
Georg Brandl26543b12008-01-21 18:36:51 +000010678- Issue #1882: when compiling code from a string, encoding cookies in the
10679 second line of code were not always recognized correctly.
10680
Georg Brandl14404b62008-01-19 19:27:05 +000010681- Issue #1679: "0x" was taken as a valid integer literal.
10682
Georg Brandl6caad7d2008-01-26 14:19:22 +000010683- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000010684 added.
10685
Christian Heimesc94e2b52008-01-14 04:13:37 +000010686- sys.float_info / PyFloat_GetInfo: The floating point information
10687 object was converted from a dict to a specialized structseq object.
10688
Georg Brandl3ee81df2008-05-17 18:14:43 +000010689- Patch #1816: Added sys.flags structseq. It exposes the status of
10690 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000010691
Georg Brandl3ee81df2008-05-17 18:14:43 +000010692- Objects/structseq.c: Implemented new structseq representation. The

10694 readable.
Christian Heimes9c201962008-01-14 03:33:52 +000010695
Georg Brandl3ee81df2008-05-17 18:14:43 +000010696- Patch #1700288: added a type attribute cache that caches method

10705 envvar and sys.dont_write_bytecode attribute. All these can be set
10706 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +000010707
Georg Brandl3ee81df2008-05-17 18:14:43 +000010708- Improve some exception messages when Windows fails to load an
10709 extension module. Now we get for example '%1 is not a valid Win32
10710 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000010711

Christian Heimes0a8143f2007-12-18 23:22:54 +000010717- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +000010718 and INF. float("nan"), float("inf") and float("-inf") now work on
10719 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +000010720
Georg Brandl3ee81df2008-05-17 18:14:43 +000010721- Compiler now generates simpler and faster code for dictionary
10722 literals. The oparg for BUILD_MAP now indicates an estimated
10723 dictionary size. There is a new opcode, STORE_MAP, for adding
10724 entries to the dictionary.

10767
Georg Brandl21e99f42010-03-07 15:23:59 +000010768- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +000010769 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
10770 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +000010771
Georg Brandl3ee81df2008-05-17 18:14:43 +000010772- Issue #1686386: Tuple's tp_repr did not take into account the
10773 possibility of having a self-referential tuple, which is possible
10774 from C code. Nor did object's tp_str consider that a type's tp_str
10775 could do something that could lead to an inifinite recursion.
10776 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
10777 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010779- Issue #1164: It was possible to trigger deadlock when using the
10780 'print' statement to write to a file since the GIL was not released
10781 as needed. Now PyObject_Print() does the right thing along with
10782 various tp_print implementations of the built-in types and those in
10783 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +000010784
Georg Brandl3ee81df2008-05-17 18:14:43 +000010785- Issue #1147: Exceptions were directly allowing string exceptions in
10786 their throw() method even though string exceptions no longer
10787 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +000010792- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +000010793 PyObject_Call() never calling back out to Python code to trigger
10794 recursion depth updates/checks. Required the creation of a static
10795 RuntimeError instance in case normalizing an exception put the
10796 recursion check value past its limit. Fixes crashers
10797 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010813 __*__ attributes. (Some already existed, e.g., __doc__ and
10814 __name__.)

10820 calls.
10821
Collin Winter62903052007-05-18 23:11:24 +000010822- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +000010823 "except E as target:". This is to provide forwards compatibility
10824 with Python 3.0.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010837 translations that only remove characters without re-mapping the
10838 remaining characters.
10839
Georg Brandl5cb76c12007-03-21 09:00:39 +000010840- Patch #1682205: a TypeError while unpacking an iterable is no longer

10844
Guido van Rossum143b5642007-03-23 04:58:42 +000010845- Bug #1683368: The object.__init__() and object.__new__() methods are
10846 now stricter in rejecting excess arguments. The only time when
10847 either allows excess arguments is when it is not overridden and the
10848 other one is. For backwards compatibility, when both are
10849 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010850 warning later). Also, type.__init__() insists on the same signature
10851 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000010852
Georg Brandl3ee81df2008-05-17 18:14:43 +000010853- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10854 object to complex using its __complex__() method before falling back
10855 to the __float__() method. Therefore, the functions in the cmath
10856 module now can operate on objects that define a __complex__()
10857 method.
Georg Brandl2b869942007-03-17 16:08:45 +000010858
Georg Brandl3ee81df2008-05-17 18:14:43 +000010859- Patch #1623563: allow __class__ assignment for classes with

10861 same slot names.

10868 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +000010875- Bug #1678647: write a newline after printing an exception in any
10876 case, even when converting the value to a string failed.
10877
Georg Brandl871f1bc2007-03-12 13:17:36 +000010878- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010879 its argument, if it exists. If not, it will work like before. This
10880 allows customizing the output of dir() in the presence of a
10881 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +000010889- Patch #1491866: change the complex() constructor to allow
10890 parthensized forms. This means complex(repr(x)) now works instead of
10891 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010892
Georg Brandlaa2321b2007-03-07 00:40:28 +000010893- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +000010894 makes the filenames the warning module prints much more sensible
10895 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +000010908- Patch #1674228: when assigning a slice (old-style), check for the

10910
Georg Brandl3ee81df2008-05-17 18:14:43 +000010911- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +000011463- Patch #1530482: add pydoc.render_doc() which returns the
11464 documentation for a thing instead of paging it to stdout, which

Georg Brandl3ee81df2008-05-17 18:14:43 +000011480 are set for invalid interpolation sequences that would lead to
11481 errors on reading back those values.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011536- unittest now verifies more of its assumptions. In particular,
11537 TestCase and TestSuite subclasses (not instances) are no longer
11538 accepted in TestSuite.addTest(). This should cause no

11540 -- the failure just occurred later, with a more cumbersome
11541 exception.

11810 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000011811
Georg Brandl3ee81df2008-05-17 18:14:43 +000011812- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000011821- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000011822 that the SMTP.starttls() caller no longer needs to call ehlo()
11823 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000011824 does not claim to support starttls. Adds the
11825 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000011868- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000011869 works as expected. ``mmap.find`` also takes an optional ``end``

11906 complex, tuple, list, dict, set, and frozenset. Formerly, it would
11907 silently miscode subclasses of those types. Now, it raises a
11908 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000011909

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000011923- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000011924 time so that opening a database previously created with the DB_DUP
11925 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11926 opens. Specifically: dictionary assignment to a DB object will
11927 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000012214- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +000012215 periodic threadstate and signal checking in tight loops. By
12216 default, this option is turned-off. It should only be enabled in
12217 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000012218

12272 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000012273
Georg Brandl3ee81df2008-05-17 18:14:43 +000012274- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
12275 to ``PyTuple_SetItem``, it can be used to populate a brand new

12290 of w# format code incorrectly truncated the length to an int, even
12291 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
12292 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000012293

12313 (relevant to strings and sequences of more than 2**31 items).
12314

12316 outside of pystate.c and should not be necessary.
12317
Georg Brandl3ee81df2008-05-17 18:14:43 +000012318- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
12319 absolute imports. In earlier versions they might have used relative
12320 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000012321
Georg Brandl3ee81df2008-05-17 18:14:43 +000012322- Added case insensitive comparison methods ``PyOS_stricmp(char*,
12323 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +000012348- Removed the macfs module. It had been deprecated since Python 2.5.
12349 This lead to the deprecation of macostools.touched() as it relied
12350 solely on macfs and was a no-op under OS X.
