1Python History 2-------------- 3 4This file contains the release messages for previous Python releases. 5As you read on you go back to the dark ages of Python's history. 6(Note: news about 2.5c2 and later 2.5 releases is in the Misc/NEWS 7file of the release25-maint branch.) 8 9 10====================================================================== 11 12 13What's New in Python 2.5 release candidate 1? 14============================================= 15 16*Release date: 17-AUG-2006* 17 18Core and builtins 19----------------- 20 21- Unicode objects will no longer raise an exception when being 22 compared equal or unequal to a string and a UnicodeDecodeError 23 exception occurs, e.g. as result of a decoding failure. 24 25 Instead, the equal (==) and unequal (!=) comparison operators will 26 now issue a UnicodeWarning and interpret the two objects as 27 unequal. The UnicodeWarning can be filtered as desired using 28 the warning framework, e.g. silenced completely, turned into an 29 exception, logged, etc. 30 31 Note that compare operators other than equal and unequal will still 32 raise UnicodeDecodeError exceptions as they've always done. 33 34- Fix segfault when doing string formatting on subclasses of long. 35 36- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines 37 with new-style classes. 38 39- Fix bug related to __len__ functions returning negative values with 40 classic classes. 41 42- Patch #1538606, Fix __index__() clipping. There were some problems 43 discovered with the API and how integers that didn't fit into Py_ssize_t 44 were handled. This patch attempts to provide enough alternatives 45 to effectively use __index__. 46 47- Bug #1536021: __hash__ may now return long int; the final hash 48 value is obtained by invoking hash on the long int. 49 50- Bug #1536786: buffer comparison could emit a RuntimeWarning. 51 52- Bug #1535165: fixed a segfault in input() and raw_input() when 53 sys.stdin is closed. 54 55- On Windows, the PyErr_Warn function is now exported from 56 the Python dll again. 57 58- Bug #1191458: tracing over for loops now produces a line event 59 on each iteration. Fixing this problem required changing the .pyc 60 magic number. This means that .pyc files generated before 2.5c1 61 will be regenerated. 62 63- Bug #1333982: string/number constants were inappropriately stored 64 in the byte code and co_consts even if they were not used, ie 65 immediately popped off the stack. 66 67- Fixed a reference-counting problem in property(). 68 69 70Library 71------- 72 73- Fix a bug in the ``compiler`` package that caused invalid code to be 74 generated for generator expressions. 75 76- The distutils version has been changed to 2.5.0. The change to 77 keep it programmatically in sync with the Python version running 78 the code (introduced in 2.5b3) has been reverted. It will continue 79 to be maintained manually as static string literal. 80 81- If the Python part of a ctypes callback function returns None, 82 and this cannot be converted to the required C type, an exception is 83 printed with PyErr_WriteUnraisable. Before this change, the C 84 callback returned arbitrary values to the calling code. 85 86- The __repr__ method of a NULL ctypes.py_object() no longer raises 87 an exception. 88 89- uuid.UUID now has a bytes_le attribute. This returns the UUID in 90 little-endian byte order for Windows. In addition, uuid.py gained some 91 workarounds for clocks with low resolution, to stop the code yielding 92 duplicate UUIDs. 93 94- Patch #1540892: site.py Quitter() class attempts to close sys.stdin 95 before raising SystemExit, allowing IDLE to honor quit() and exit(). 96 97- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize. 98 99- Patch #1536071: trace.py should now find the full module name of a 100 file correctly even on Windows. 101 102- logging's atexit hook now runs even if the rest of the module has 103 already been cleaned up. 104 105- Bug #1112549, fix DoS attack on cgi.FieldStorage. 106 107- Bug #1531405, format_exception no longer raises an exception if 108 str(exception) raised an exception. 109 110- Fix a bug in the ``compiler`` package that caused invalid code to be 111 generated for nested functions. 112 113 114Extension Modules 115----------------- 116 117- Patch #1511317: don't crash on invalid hostname (alias) info. 118 119- Patch #1535500: fix segfault in BZ2File.writelines and make sure it 120 raises the correct exceptions. 121 122- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The 123 '-no-stack-protector' compiler flag for OpenBSD has been removed. 124 125- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now 126 uses the _as_parameter_ attribute when objects are passed to foreign 127 function calls. The ctypes version number was changed to 1.0.1. 128 129- Bug #1530559, struct.pack raises TypeError where it used to convert. 130 Passing float arguments to struct.pack when integers are expected 131 now triggers a DeprecationWarning. 132 133 134Tests 135----- 136 137- test_socketserver should now work on cygwin and not fail sporadically 138 on other platforms. 139 140- test_mailbox should now work on cygwin versions 2006-08-10 and later. 141 142- Bug #1535182: really test the xreadlines() method of bz2 objects. 143 144- test_threading now skips testing alternate thread stack sizes on 145 platforms that don't support changing thread stack size. 146 147 148Documentation 149------------- 150 151- Patch #1534922: unittest docs were corrected and enhanced. 152 153 154Build 155----- 156 157- Bug #1535502, build _hashlib on Windows, and use masm assembler 158 code in OpenSSL. 159 160- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd. 161 162- Bug #1530448, ctypes build failure on Solaris 10 was fixed. 163 164 165C API 166----- 167 168- New API for Unicode rich comparisons: PyUnicode_RichCompare() 169 170- Bug #1069160. Internal correctness changes were made to 171 ``PyThreadState_SetAsyncExc()``. A test case was added, and 172 the documentation was changed to state that the return value 173 is always 1 (normal) or 0 (if the specified thread wasn't found). 174 175 176What's New in Python 2.5 beta 3? 177================================ 178 179*Release date: 03-AUG-2006* 180 181Core and builtins 182----------------- 183 184- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously 185 returned a long (see PEP 353). 186 187- Bug #1515471: string.replace() accepts character buffers again. 188 189- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn(). 190 This provides the proper warning for struct.pack(). 191 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx(). 192 193- Patch #1531113: Fix augmented assignment with yield expressions. 194 Also fix a SystemError when trying to assign to yield expressions. 195 196- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance 197 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is 198 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid 199 excessive filesystem operations during imports. 200 201- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some 202 operations on signed longs that are formally undefined by C. 203 Unfortunately, at least one compiler now cares about that, so complicated 204 the code to make that compiler happy again. 205 206- Bug #1524310: Properly report errors from FindNextFile in os.listdir. 207 208- Patch #1232023: Stop including current directory in search 209 path on Windows. 210 211- Fix some potential crashes found with failmalloc. 212 213- Fix warnings reported by Klocwork's static analysis tool. 214 215- Bug #1512814, Fix incorrect lineno's when code within a function 216 had more than 255 blank lines. 217 218- Patch #1521179: Python now accepts the standard options ``--help`` and 219 ``--version`` as well as ``/?`` on Windows. 220 221- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works 222 again. Fixing this problem required changing the .pyc magic number. 223 This means that .pyc files generated before 2.5b3 will be regenerated. 224 225- Bug #1524317: Compiling Python ``--without-threads`` failed. 226 The Python core compiles again, and, in a build without threads, the 227 new ``sys._current_frames()`` returns a dictionary with one entry, 228 mapping the faux "thread id" 0 to the current frame. 229 230- Bug #1525447: build on MacOS X on a case-sensitive filesystem. 231 232 233Library 234------- 235 236- Fix #1693149. Now you can pass several modules separated by 237 comma to trace.py in the same --ignore-module option. 238 239- Correction of patch #1455898: In the mbcs decoder, set final=False 240 for stream decoder, but final=True for the decode function. 241 242- os.urandom no longer masks unrelated exceptions like SystemExit or 243 KeyboardInterrupt. 244 245- Bug #1525866: Don't copy directory stat times in 246 shutil.copytree on Windows 247 248- Bug #1002398: The documentation for os.path.sameopenfile now correctly 249 refers to file descriptors, not file objects. 250 251- The renaming of the xml package to xmlcore, and the import hackery done 252 to make it appear at both names, has been removed. Bug #1511497, 253 #1513611, and probably others. 254 255- Bug #1441397: The compiler module now recognizes module and function 256 docstrings correctly as it did in Python 2.4. 257 258- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally 259 lost that tests are sorted by name before being run. This rarely 260 matters for well-written tests, but can create baffling symptoms if 261 side effects from one test to the next affect outcomes. ``DocTestFinder`` 262 has been changed to sort the list of tests it returns. 263 264- The distutils version has been changed to 2.5.0, and is now kept 265 in sync with sys.version_info[:3]. 266 267- Bug #978833: Really close underlying socket in _socketobject.close. 268 269- Bug #1459963: urllib and urllib2 now normalize HTTP header names with 270 title(). 271 272- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback 273 to recursive calls and call it with the failing package name. 274 275- Bug #1525817: Don't truncate short lines in IDLE's tool tips. 276 277- Patch #1515343: Fix printing of deprecated string exceptions with a 278 value in the traceback module. 279 280- Resync optparse with Optik 1.5.3: minor tweaks for/to tests. 281 282- Patch #1524429: Use repr() instead of backticks in Tkinter again. 283 284- Bug #1520914: Change time.strftime() to accept a zero for any position in its 285 argument tuple. For arguments where zero is illegal, the value is forced to 286 the minimum value that is correct. This is to support an undocumented but 287 common way people used to fill in inconsequential information in the time 288 tuple pre-2.4. 289 290- Patch #1220874: Update the binhex module for Mach-O. 291 292- The email package has improved RFC 2231 support, specifically for 293 recognizing the difference between encoded (name*0*=<blah>) and non-encoded 294 (name*0=<blah>) parameter continuations. This may change the types of 295 values returned from email.message.Message.get_param() and friends. 296 Specifically in some cases where non-encoded continuations were used, 297 get_param() used to return a 3-tuple of (None, None, string) whereas now it 298 will just return the string (since non-encoded continuations don't have 299 charset and language parts). 300 301 Also, whereas % values were decoded in all parameter continuations, they are 302 now only decoded in encoded parameter parts. 303 304- Bug #1517990: IDLE keybindings on MacOS X now work correctly 305 306- Bug #1517996: IDLE now longer shows the default Tk menu when a 307 path browser, class browser or debugger is the frontmost window on MacOS X 308 309- Patch #1520294: Support for getset and member descriptors in types.py, 310 inspect.py, and pydoc.py. Specifically, this allows for querying the type 311 of an object against these built-in types and more importantly, for getting 312 their docstrings printed in the interactive interpreter's help() function. 313 314 315Extension Modules 316----------------- 317 318- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during 319 a socket operation on a socket with a timeout, the exception will be 320 caught correctly. Previously, the exception was not caught. 321 322- Patch #1529514: The _ctypes extension is now compiled on more 323 openbsd target platforms. 324 325- The ``__reduce__()`` method of the new ``collections.defaultdict`` had 326 a memory leak, affecting pickles and deep copies. 327 328- Bug #1471938: Fix curses module build problem on Solaris 8; patch by 329 Paul Eggert. 330 331- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry. 332 333- Patch #1521817: Index range checking on ctypes arrays containing 334 exactly one element enabled again. This allows iterating over these 335 arrays, without the need to check the array size before. 336 337- Bug #1521375: When the code in ctypes.util.find_library was 338 run with root privileges, it could overwrite or delete 339 /dev/null in certain cases; this is now fixed. 340 341- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the 342 default mode for loading shared libraries in ctypes. 343 344- Because of a misspelled preprocessor symbol, ctypes was always 345 compiled without thread support; this is now fixed. 346 347- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename 348 methods now allow their database parameter to be None as the 349 sleepycat API allows. 350 351- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different 352 bluetooth API compared with Linux and FreeBSD. 353 354Tests 355----- 356 357- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of 358 how long the test file should take to play. Now accepts taking 2.93 secs 359 (exact time) +/- 10% instead of the hard-coded 3.1 sec. 360 361- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``, 362 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when 363 run via ``regrtest.py``. Now they do. 364 365Build 366----- 367 368- Bug #1439538: Drop usage of test -e in configure as it is not portable. 369 370Mac 371--- 372 373- PythonLauncher now works correctly when the path to the script contains 374 characters that are treated specially by the shell (such as quotes). 375 376- Bug #1527397: PythonLauncher now launches scripts with the working directory 377 set to the directory that contains the script instead of the user home 378 directory. That latter was an implementation accident and not what users 379 expect. 380 381 382What's New in Python 2.5 beta 2? 383================================ 384 385*Release date: 11-JUL-2006* 386 387Core and builtins 388----------------- 389 390- Bug #1441486: The literal representation of -(sys.maxint - 1) 391 again evaluates to a int object, not a long. 392 393- Bug #1501934: The scope of global variables that are locally assigned 394 using augmented assignment is now correctly determined. 395 396- Bug #927248: Recursive method-wrapper objects can now safely 397 be released. 398 399- Bug #1417699: Reject locale-specific decimal point in float() 400 and atof(). 401 402- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to 403 omit a default "error" argument for NULL pointer. This allows 404 the parser to take a codec from cjkcodecs again. 405 406- Bug #1519018: 'as' is now validated properly in import statements. 407 408- On 64 bit systems, int literals that use less than 64 bits are 409 now ints rather than longs. 410 411- Bug #1512814, Fix incorrect lineno's when code at module scope 412 started after line 256. 413 414- New function ``sys._current_frames()`` returns a dict mapping thread 415 id to topmost thread stack frame. This is for expert use, and is 416 especially useful for debugging application deadlocks. The functionality 417 was previously available in Fazal Majid's ``threadframe`` extension 418 module, but it wasn't possible to do this in a wholly threadsafe way from 419 an extension. 420 421Library 422------- 423 424- Bug #1257728: Mention Cygwin in distutils error message about a missing 425 VS 2003. 426 427- Patch #1519566: Update turtle demo, make begin_fill idempotent. 428 429- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK 430 environment variable to be set in order to the SDK environment 431 for finding the compiler, include files, etc. 432 433- Bug #1515998: Properly generate logical ids for files in bdist_msi. 434 435- warnings.py now ignores ImportWarning by default 436 437- string.Template() now correctly handles tuple-values. Previously, 438 multi-value tuples would raise an exception and single-value tuples would 439 be treated as the value they contain, instead. 440 441- Bug #822974: Honor timeout in telnetlib.{expect,read_until} 442 even if some data are received. 443 444- Bug #1267547: Put proper recursive setup.py call into the 445 spec file generated by bdist_rpm. 446 447- Bug #1514693: Update turtle's heading when switching between 448 degrees and radians. 449 450- Reimplement turtle.circle using a polyline, to allow correct 451 filling of arcs. 452 453- Bug #1514703: Only setup canvas window in turtle when the canvas 454 is created. 455 456- Bug #1513223: .close() of a _socketobj now releases the underlying 457 socket again, which then gets closed as it becomes unreferenced. 458 459- Bug #1504333: Make sgmllib support angle brackets in quoted 460 attribute values. 461 462- Bug #853506: Fix IPv6 address parsing in unquoted attributes in 463 sgmllib ('[' and ']' were not accepted). 464 465- Fix a bug in the turtle module's end_fill function. 466 467- Bug #1510580: The 'warnings' module improperly required that a Warning 468 category be either a types.ClassType and a subclass of Warning. The proper 469 check is just that it is a subclass with Warning as the documentation states. 470 471- The compiler module now correctly compiles the new try-except-finally 472 statement (bug #1509132). 473 474- The wsgiref package is now installed properly on Unix. 475 476- A bug was fixed in logging.config.fileConfig() which caused a crash on 477 shutdown when fileConfig() was called multiple times. 478 479- The sqlite3 module did cut off data from the SQLite database at the first 480 null character before sending it to a custom converter. This has been fixed 481 now. 482 483Extension Modules 484----------------- 485 486- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This 487 means that select() on sockets > FD_SETSIZE (typically 1024) work again. 488 The patch makes sockets use poll() internally where available. 489 490- Assigning None to pointer type fields in ctypes structures possible 491 overwrote the wrong fields, this is fixed now. 492 493- Fixed a segfault in _ctypes when ctypes.wintypes were imported 494 on non-Windows platforms. 495 496- Bug #1518190: The ctypes.c_void_p constructor now accepts any 497 integer or long, without range checking. 498 499- Patch #1517790: It is now possible to use custom objects in the ctypes 500 foreign function argtypes sequence as long as they provide a from_param 501 method, no longer is it required that the object is a ctypes type. 502 503- The '_ctypes' extension module now works when Python is configured 504 with the --without-threads option. 505 506- Bug #1513646: os.access on Windows now correctly determines write 507 access, again. 508 509- Bug #1512695: cPickle.loads could crash if it was interrupted with 510 a KeyboardInterrupt. 511 512- Bug #1296433: parsing XML with a non-default encoding and 513 a CharacterDataHandler could crash the interpreter in pyexpat. 514 515- Patch #1516912: improve Modules support for OpenVMS. 516 517Build 518----- 519 520- Automate Windows build process for the Win64 SSL module. 521 522- 'configure' now detects the zlib library the same way as distutils. 523 Previously, the slight difference could cause compilation errors of the 524 'zlib' module on systems with more than one version of zlib. 525 526- The MSI compileall step was fixed to also support a TARGETDIR 527 with spaces in it. 528 529- Bug #1517388: sqlite3.dll is now installed on Windows independent 530 of Tcl/Tk. 531 532- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old 533 trying to be installed even though it's empty. 534 535Tests 536----- 537 538- Call os.waitpid() at the end of tests that spawn child processes in order 539 to minimize resources (zombies). 540 541Documentation 542------------- 543 544- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the 545 documentation for the warnings module. 546 547- Patch #1509163: MS Toolkit Compiler no longer available. 548 549- Patch #1504046: Add documentation for xml.etree. 550 551 552What's New in Python 2.5 beta 1? 553================================ 554 555*Release date: 20-JUN-2006* 556 557Core and builtins 558----------------- 559 560- Patch #1507676: Error messages returned by invalid abstract object operations 561 (such as iterating over an integer) have been improved and now include the 562 type of the offending object to help with debugging. 563 564- Bug #992017: A classic class that defined a __coerce__() method that returned 565 its arguments swapped would infinitely recurse and segfault the interpreter. 566 567- Fix the socket tests so they can be run concurrently. 568 569- Removed 5 integers from C frame objects (PyFrameObject). 570 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted. 571 572- Bug #532646: object.__call__() will continue looking for the __call__ 573 attribute on objects until one without one is found. This leads to recursion 574 when you take a class and set its __call__ attribute to an instance of the 575 class. Originally fixed for classic classes, but this fix is for new-style. 576 Removes the infinite_rec_3 crasher. 577 578- The string and unicode methods startswith() and endswith() now accept 579 a tuple of prefixes/suffixes to look for. Implements RFE #1491485. 580 581- Buffer objects, at the C level, never used the char buffer 582 implementation even when the char buffer for the wrapped object was 583 explicitly requested (originally returned the read or write buffer). 584 Now a TypeError is raised if the char buffer is not present but is 585 requested. 586 587- Patch #1346214: Statements like "if 0: suite" are now again optimized 588 away like they were in Python 2.4. 589 590- Builtin exceptions are now full-blown new-style classes instead of 591 instances pretending to be classes, which speeds up exception handling 592 by about 80% in comparison to 2.5a2. 593 594- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to 595 Unicode 4.1. 596 597- Patch #921466: sys.path_importer_cache is now used to cache valid and 598 invalid file paths for the built-in import machinery which leads to 599 fewer open calls on startup. 600 601- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power- 602 of-2 bases. The largest speedup is for inputs with about 1000 decimal 603 digits. Conversion from non-power-of-2 bases remains quadratic-time in 604 the number of input digits (it was and remains linear-time for bases 605 2, 4, 8, 16 and 32). 606 607- Bug #1334662: ``int(string, base)`` could deliver a wrong answer 608 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented 609 an integer close to ``sys.maxint``. This was repaired by patch 610 #1335972, which also gives a nice speedup. 611 612- Patch #1337051: reduced size of frame objects. 613 614- PyErr_NewException now accepts a tuple of base classes as its 615 "base" parameter. 616 617- Patch #876206: function call speedup by retaining allocated frame 618 objects. 619 620- Bug #1462152: file() now checks more thoroughly for invalid mode 621 strings and removes a possible "U" before passing the mode to the 622 C library function. 623 624- Patch #1488312, Fix memory alignment problem on SPARC in unicode 625 626- Bug #1487966: Fix SystemError with conditional expression in assignment 627 628- WindowsError now has two error code attributes: errno, which carries 629 the error values from errno.h, and winerror, which carries the error 630 values from winerror.h. Previous versions put the winerror.h values 631 (from GetLastError()) into the errno attribute. 632 633- Patch #1475845: Raise IndentationError for unexpected indent. 634 635- Patch #1479181: split open() and file() from being aliases for each other. 636 637- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()`` 638 methods were always silently ignored by dictionaries when comparing keys. 639 They are now passed through (except when using the C API function 640 ``PyDict_GetItem()``, whose semantics did not change). 641 642- Bug #1456209: In some obscure cases it was possible for a class with a 643 custom ``__eq__()`` method to confuse dict internals when class instances 644 were used as a dict's keys and the ``__eq__()`` method mutated the dict. 645 No, you don't have any code that did this ;-) 646 647Extension Modules 648----------------- 649 650- Bug #1295808: expat symbols should be namespaced in pyexpat 651 652- Patch #1462338: Upgrade pyexpat to expat 2.0.0 653 654- Change binascii.hexlify to accept a read-only buffer instead of only a char 655 buffer and actually follow its documentation. 656 657- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder. 658 659- Patch #1478788 (modified version): The functional extension module has 660 been renamed to _functools and a functools Python wrapper module added. 661 This provides a home for additional function related utilities that are 662 not specifically about functional programming. See PEP 309. 663 664- Patch #1493701: performance enhancements for struct module. 665 666- Patch #1490224: time.altzone is now set correctly on Cygwin. 667 668- Patch #1435422: zlib's compress and decompress objects now have a 669 copy() method. 670 671- Patch #1454481: thread stack size is now tunable at runtime for thread 672 enabled builds on Windows and systems with Posix threads support. 673 674- On Win32, os.listdir now supports arbitrarily-long Unicode path names 675 (up to the system limit of 32K characters). 676 677- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}. 678 As a result, these functions now raise WindowsError instead of OSError. 679 680- ``time.clock()`` on Win64 should use the high-performance Windows 681 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit 682 Windows platforms). 683 684- Calling Tk_Init twice is refused if the first call failed as that 685 may deadlock. 686 687- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to 688 accept it without potentially using an uninitialized pointer. 689 690- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods 691 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF 692 patch numbers 1494885 and 1494902] 693 694- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class. 695 [pybsddb project SF patch number 1466734] 696 697- bsddb: fix DBCursor.pget() bug with keyword argument names when no data 698 parameter is supplied. [SF pybsddb bug #1477863] 699 700- bsddb: the __len__ method of a DB object has been fixed to return correct 701 results. It could previously incorrectly return 0 in some cases. 702 Fixes SF bug 1493322 (pybsddb bug 1184012). 703 704- bsddb: the bsddb.dbtables Modify method now raises the proper error and 705 aborts the db transaction safely when a modifier callback fails. 706 Fixes SF python patch/bug #1408584. 707 708- bsddb: multithreaded DB access using the simple bsddb module interface 709 now works reliably. It has been updated to use automatic BerkeleyDB 710 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry 711 database calls that would previously deadlock. [SF python bug #775414] 712 713- Patch #1446489: add support for the ZIP64 extensions to zipfile. 714 715- Patch #1506645: add Python wrappers for the curses functions 716 is_term_resized, resize_term and resizeterm. 717 718Library 719------- 720 721- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox 722 functions. 723 724- Patch #812986: Update turtle output even if not tracing. 725 726- Patch #1494750: Destroy master after deleting children in 727 Tkinter.BaseWidget. 728 729- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap. 730 731- Patch #763580: Add name and value arguments to Tkinter variable 732 classes. 733 734- Bug #1117556: SimpleHTTPServer now tries to find and use the system's 735 mime.types file for determining MIME types. 736 737- Bug #1339007: Shelf objects now don't raise an exception in their 738 __del__ method when initialization failed. 739 740- Patch #1455898: The MBCS codec now supports the incremental mode for 741 double-byte encodings. 742 743- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to 744 guarantee that adjacent triples in the return list always describe 745 non-adjacent blocks. Previously, a pair of matching blocks could end 746 up being described by multiple adjacent triples that formed a partition 747 of the matching pair. 748 749- Bug #1498146: fix optparse to handle Unicode strings in option help, 750 description, and epilog. 751 752- Bug #1366250: minor optparse documentation error. 753 754- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately; 755 clarify docs. 756 757- The wsgiref package has been added to the standard library. 758 759- The functions update_wrapper() and wraps() have been added to the functools 760 module. These make it easier to copy relevant metadata from the original 761 function when writing wrapper functions. 762 763- The optional ``isprivate`` argument to ``doctest.testmod()``, and the 764 ``doctest.is_private()`` function, both deprecated in 2.4, were removed. 765 766- Patch #1359618: Speed up charmap encoder by using a trie structure 767 for lookup. 768 769- The functions in the ``pprint`` module now sort dictionaries by key 770 before computing the display. Before 2.5, ``pprint`` sorted a dictionary 771 if and only if its display required more than one line, although that 772 wasn't documented. The new behavior increases predictability; e.g., 773 using ``pprint.pprint(a_dict)`` in a doctest is now reliable. 774 775- Patch #1497027: try HTTP digest auth before basic auth in urllib2 776 (thanks for J. J. Lee). 777 778- Patch #1496206: improve urllib2 handling of passwords with respect to 779 default HTTP and HTTPS ports. 780 781- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite. 782 783- Patch #1281707: speed up gzip.readline. 784 785- Patch #1180296: Two new functions were added to the locale module: 786 format_string() to get the effect of "format % items" but locale-aware, 787 and currency() to format a monetary number with currency sign. 788 789- Patch #1486962: Several bugs in the turtle Tk demo module were fixed 790 and several features added, such as speed and geometry control. 791 792- Patch #1488881: add support for external file objects in bz2 compressed 793 tarfiles. 794 795- Patch #721464: pdb.Pdb instances can now be given explicit stdin and 796 stdout arguments, making it possible to redirect input and output 797 for remote debugging. 798 799- Patch #1484695: Update the tarfile module to version 0.8. This fixes 800 a couple of issues, notably handling of long file names using the 801 GNU LONGNAME extension. 802 803- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a 804 new flag when ``name`` is already the name of an option flag. 805 806- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler 807 package. 808 809- Patch #1472854: make the rlcompleter.Completer class usable on non- 810 UNIX platforms. 811 812- Patch #1470846: fix urllib2 ProxyBasicAuthHandler. 813 814- Bug #1472827: correctly escape newlines and tabs in attribute values in 815 the saxutils.XMLGenerator class. 816 817 818Build 819----- 820 821- Bug #1502728: Correctly link against librt library on HP-UX. 822 823- OpenBSD 3.9 is supported now. 824 825- Patch #1492356: Port to Windows CE. 826 827- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64. 828 829- Patch #1471883: Add --enable-universalsdk. 830 831C API 832----- 833 834Tests 835----- 836 837Tools 838----- 839 840Documentation 841------------- 842 843 844 845What's New in Python 2.5 alpha 2? 846================================= 847 848*Release date: 27-APR-2006* 849 850Core and builtins 851----------------- 852 853- Bug #1465834: 'bdist_wininst preinstall script support' was fixed 854 by converting these apis from macros into exported functions again: 855 856 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile 857 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx 858 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne 859 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString 860 PyRun_String Py_CompileString 861 862- Under COUNT_ALLOCS, types are not necessarily immortal anymore. 863 864- All uses of PyStructSequence_InitType have been changed to initialize 865 the type objects only once, even if the interpreter is initialized 866 multiple times. 867 868- Bug #1454485, array.array('u') could crash the interpreter. This was 869 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings) 870 to unicode when it didn't make sense. 'u#' now requires a unicode string. 871 872- Py_UNICODE is unsigned. It was always documented as unsigned, but 873 due to a bug had a signed value in previous versions. 874 875- Patch #837242: ``id()`` of any Python object always gives a positive 876 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and 877 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has 878 never been correct to implement a ``__hash()__`` method that returns the 879 ``id()`` of an object: 880 881 def __hash__(self): 882 return id(self) # WRONG 883 884 because a hash result must be a (short) Python int but it was always 885 possible for ``id()`` to return a Python long. However, because ``id()`` 886 could return negative values before, on a 32-bit box an ``id()`` result 887 was always usable as a hash value before this patch. That's no longer 888 necessarily so. 889 890- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c) 891 to load extension modules and now provides the dl module. As a result, 892 sys.setdlopenflags() now works correctly on these systems. (SF patch 893 #1454844) 894 895- Patch #1463867: enhanced garbage collection to allow cleanup of cycles 896 involving generators that have paused outside of any ``try`` or ``with`` 897 blocks. (In 2.5a1, a paused generator that was part of a reference 898 cycle could not be garbage collected, regardless of whether it was 899 paused in a ``try`` or ``with`` block.) 900 901Extension Modules 902----------------- 903 904- Patch #1191065: Fix preprocessor problems on systems where recvfrom 905 is a macro. 906 907- Bug #1467952: os.listdir() now correctly raises an error if readdir() 908 fails with an error condition. 909 910- Fixed bsddb.db.DBError derived exceptions so they can be unpickled. 911 912- Bug #1117761: bsddb.*open() no longer raises an exception when using 913 the cachesize parameter. 914 915- Bug #1149413: bsddb.*open() no longer raises an exception when using 916 a temporary db (file=None) with the 'n' flag to truncate on open. 917 918- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3 919 as older versions cause excessive test failures. 920 921- Patch #1062014: AF_UNIX sockets under Linux have a special 922 abstract namespace that is now fully supported. 923 924Library 925------- 926 927- Bug #1223937: subprocess.CalledProcessError reports the exit status 928 of the process using the returncode attribute, instead of 929 abusing errno. 930 931- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes 932 a doctest to be skipped (the code is not run, and the expected output 933 or exception is ignored). 934 935- Fixed contextlib.nested to cope with exceptions being raised and 936 caught inside exit handlers. 937 938- Updated optparse module to Optik 1.5.1 (allow numeric constants in 939 hex, octal, or binary; add ``append_const`` action; keep going if 940 gettext cannot be imported; added ``OptionParser.destroy()`` method; 941 added ``epilog`` for better help generation). 942 943- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when 944 called from a thread spawned as a side effect of importing a module. 945 946- The pydoc module now supports documenting packages contained in 947 .zip or .egg files. 948 949- The pkgutil module now has several new utility functions, such 950 as ``walk_packages()`` to support working with packages that are either 951 in the filesystem or zip files. 952 953- The mailbox module can now modify and delete messages from 954 mailboxes, in addition to simply reading them. Thanks to Gregory 955 K. Johnson for writing the code, and to the 2005 Google Summer of 956 Code for funding his work. 957 958- The ``__del__`` method of class ``local`` in module ``_threading_local`` 959 returned before accomplishing any of its intended cleanup. 960 961- Patch #790710: Add breakpoint command lists in pdb. 962 963- Patch #1063914: Add Tkinter.Misc.clipboard_get(). 964 965- Patch #1191700: Adjust column alignment in bdb breakpoint lists. 966 967- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on 968 Windows. Bug #1469163. 969 970- The warnings, linecache, inspect, traceback, site, and doctest modules 971 were updated to work correctly with modules imported from zipfiles or 972 via other PEP 302 __loader__ objects. 973 974- Patch #1467770: Reduce usage of subprocess._active to processes which 975 the application hasn't waited on. 976 977- Patch #1462222: Fix Tix.Grid. 978 979- Fix exception when doing glob.glob('anything*/') 980 981- The pstats.Stats class accepts an optional stream keyword argument to 982 direct output to an alternate file-like object. 983 984Build 985----- 986 987- The Makefile now has a reindent target, which runs reindent.py on 988 the library. 989 990- Patch #1470875: Building Python with MS Free Compiler 991 992- Patch #1161914: Add a python-config script. 993 994- Patch #1324762:Remove ccpython.cc; replace --with-cxx with 995 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was 996 specified. (Can be overridden by explicitly setting LINKCC.) Decouple 997 CXX from --with-cxx-main, see description in README. 998 999- Patch #1429775: Link extension modules with the shared libpython. 1000 1001- Fixed a libffi build problem on MIPS systems. 1002 1003- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV`` 1004 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs, 1005 and "%zu" for unsigned integers of type ``size_t``. 1006 1007Tests 1008----- 1009 1010- test_contextlib now checks contextlib.nested can cope with exceptions 1011 being raised and caught inside exit handlers. 1012 1013- test_cmd_line now checks operation of the -m and -c command switches 1014 1015- The test_contextlib test in 2.5a1 wasn't actually run unless you ran 1016 it separately and by hand. It also wasn't cleaning up its changes to 1017 the current Decimal context. 1018 1019- regrtest.py now has a -M option to run tests that test the new limits of 1020 containers, on 64-bit architectures. Running these tests is only sensible 1021 on 64-bit machines with more than two gigabytes of memory. The argument 1022 passed is the maximum amount of memory for the tests to use. 1023 1024Tools 1025----- 1026 1027- Added the Python benchmark suite pybench to the Tools/ directory; 1028 contributed by Marc-Andre Lemburg. 1029 1030Documentation 1031------------- 1032 1033- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``. 1034 1035- PEP 343: Added Context Types section to the library reference 1036 and attempted to bring other PEP 343 related documentation into 1037 line with the implementation and/or python-dev discussions. 1038 1039- Bug #1337990: clarified that ``doctest`` does not support examples 1040 requiring both expected output and an exception. 1041 1042 1043What's New in Python 2.5 alpha 1? 1044================================= 1045 1046*Release date: 05-APR-2006* 1047 1048Core and builtins 1049----------------- 1050 1051- PEP 338: -m command line switch now delegates to runpy.run_module 1052 allowing it to support modules in packages and zipfiles 1053 1054- On Windows, .DLL is not an accepted file name extension for 1055 extension modules anymore; extensions are only found if they 1056 end in .PYD. 1057 1058- Bug #1421664: sys.stderr.encoding is now set to the same value as 1059 sys.stdout.encoding. 1060 1061- __import__ accepts keyword arguments. 1062 1063- Patch #1460496: round() now accepts keyword arguments. 1064 1065- Fixed bug #1459029 - unicode reprs were double-escaped. 1066 1067- Patch #1396919: The system scope threads are reenabled on FreeBSD 1068 5.4 and later versions. 1069 1070- Bug #1115379: Compiling a Unicode string with an encoding declaration 1071 now gives a SyntaxError. 1072 1073- Previously, Python code had no easy way to access the contents of a 1074 cell object. Now, a ``cell_contents`` attribute has been added 1075 (closes patch #1170323). 1076 1077- Patch #1123430: Python's small-object allocator now returns an arena to 1078 the system ``free()`` when all memory within an arena becomes unused 1079 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never 1080 freed. Some applications will see a drop in virtual memory size now, 1081 especially long-running applications that, from time to time, temporarily 1082 use a large number of small objects. Note that when Python returns an 1083 arena to the platform C's ``free()``, there's no guarantee that the 1084 platform C library will in turn return that memory to the operating system. 1085 The effect of the patch is to stop making that impossible, and in tests it 1086 appears to be effective at least on Microsoft C and gcc-based systems. 1087 Thanks to Evan Jones for hard work and patience. 1088 1089- Patch #1434038: property() now uses the getter's docstring if there is 1090 no "doc" argument given. This makes it possible to legitimately use 1091 property() as a decorator to produce a read-only property. 1092 1093- PEP 357, patch 1436368: add an __index__ method to int/long and a matching 1094 nb_index slot to the PyNumberMethods struct. The slot is consulted instead 1095 of requiring an int or long in slicing and a few other contexts, enabling 1096 other objects (e.g. Numeric Python's integers) to be used as slice indices. 1097 1098- Fixed various bugs reported by Coverity's Prevent tool. 1099 1100- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the 1101 new exception base class, BaseException, which has a new message attribute. 1102 KeyboardInterrupt and SystemExit to directly inherit from BaseException now. 1103 Raising a string exception now raises a DeprecationWarning. 1104 1105- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be 1106 explicitly relative, using 'from .module import name' to mean 'from the same 1107 package as this module is in. Imports without dots still default to the 1108 old relative-then-absolute, unless 'from __future__ import 1109 absolute_import' is used. 1110 1111- Properly check if 'warnings' raises an exception (usually when a filter set 1112 to "error" is triggered) when raising a warning for raising string 1113 exceptions. 1114 1115- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default. 1116 The name was removed from Include/code.h. 1117 1118- PEP 308: conditional expressions were added: (x if cond else y). 1119 1120- Patch 1433928: 1121 - The copy module now "copies" function objects (as atomic objects). 1122 - dict.__getitem__ now looks for a __missing__ hook before raising 1123 KeyError. 1124 1125- PEP 343: with statement implemented. Needs ``from __future__ import 1126 with_statement``. Use of 'with' as a variable will generate a warning. 1127 Use of 'as' as a variable will also generate a warning (unless it's 1128 part of an import statement). 1129 The following objects have __context__ methods: 1130 - The built-in file type. 1131 - The thread.LockType type. 1132 - The following types defined by the threading module: 1133 Lock, RLock, Condition, Semaphore, BoundedSemaphore. 1134 - The decimal.Context class. 1135 1136- Fix the encodings package codec search function to only search 1137 inside its own package. Fixes problem reported in patch #1433198. 1138 1139 Note: Codec packages should implement and register their own 1140 codec search function. PEP 100 has the details. 1141 1142- PEP 353: Using ``Py_ssize_t`` as the index type. 1143 1144- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging 1145 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353) 1146 now allow Python to make use of memory blocks exceeding 2**32 bytes for 1147 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited 1148 to 4-byte allocations before. 1149 1150- Patch #1400181, fix unicode string formatting to not use the locale. 1151 This is how string objects work. u'%f' could use , instead of . 1152 for the decimal point. Now both strings and unicode always use periods. 1153 1154- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8. 1155 configure would break checking curses.h. 1156 1157- Bug #959576: The pwd module is now builtin. This allows Python to be 1158 built on UNIX platforms without $HOME set. 1159 1160- Bug #1072182, fix some potential problems if characters are signed. 1161 1162- Bug #889500, fix line number on SyntaxWarning for global declarations. 1163 1164- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter. 1165 1166- Support for converting hex strings to floats no longer works. 1167 This was not portable. float('0x3') now raises a ValueError. 1168 1169- Patch #1382163: Expose Subversion revision number to Python. New C API 1170 function Py_GetBuildNumber(). New attribute sys.subversion. Build number 1171 is now displayed in interactive prompt banner. 1172 1173- Implementation of PEP 341 - Unification of try/except and try/finally. 1174 "except" clauses can now be written together with a "finally" clause in 1175 one try statement instead of two nested ones. Patch #1355913. 1176 1177- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec 1178 now encodes backslash correctly. 1179 1180- Patch #1350409: Work around signal handling bug in Visual Studio 2005. 1181 1182- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs 1183 and long longs. 1184 1185- SF Bug #1350188, "setdlopenflags" leads to crash upon "import" 1186 It was possible for dlerror() to return a NULL pointer, so 1187 it will now use a default error message in this case. 1188 1189- Replaced most Unicode charmap codecs with new ones using the 1190 new Unicode translate string feature in the builtin charmap 1191 codec; the codecs were created from the mapping tables available 1192 at ftp.unicode.org and contain a few updates (e.g. the Mac OS 1193 encodings now include a mapping for the Apple logo) 1194 1195- Added a few more codecs for Mac OS encodings 1196 1197- Sped up some Unicode operations. 1198 1199- A new AST parser implementation was completed. The abstract 1200 syntax tree is available for read-only (non-compile) access 1201 to Python code; an _ast module was added. 1202 1203- SF bug #1167751: fix incorrect code being produced for generator expressions. 1204 The following code now raises a SyntaxError: foo(a = i for i in range(10)) 1205 1206- SF Bug #976608: fix SystemError when mtime of an imported file is -1. 1207 1208- SF Bug #887946: fix segfault when redirecting stdin from a directory. 1209 Provide a warning when a directory is passed on the command line. 1210 1211- Fix segfault with invalid coding. 1212 1213- SF bug #772896: unknown encoding results in MemoryError. 1214 1215- All iterators now have a Boolean value of True. Formerly, some iterators 1216 supported a __len__() method which evaluated to False when the iterator 1217 was empty. 1218 1219- On 64-bit platforms, when __len__() returns a value that cannot be 1220 represented as a C int, raise OverflowError. 1221 1222- test__locale is skipped on OS X < 10.4 (only partial locale support is 1223 present). 1224 1225- SF bug #893549: parsing keyword arguments was broken with a few format 1226 codes. 1227 1228- Changes donated by Elemental Security to make it work on AIX 5.3 1229 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF 1230 bug #105470: test_pwd fails on 64bit system (Opteron). 1231 1232- Changes donated by Elemental Security to make it work on HP-UX 11 on 1233 Itanium2 with HP's 64-bit compiler (SF patch #1225212). 1234 1235- Disallow keyword arguments for type constructors that don't use them 1236 (fixes bug #1119418). 1237 1238- Forward UnicodeDecodeError into SyntaxError for source encoding errors. 1239 1240- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for 1241 exceptions that cause a function to exit. 1242 1243- The implementation of set() and frozenset() was revised to use its 1244 own internal data structure. Memory consumption is reduced by 1/3 1245 and there are modest speed-ups as well. The API is unchanged. 1246 1247- SF bug #1238681: freed pointer is used in longobject.c:long_pow(). 1248 1249- SF bug #1229429: PyObject_CallMethod failed to decrement some 1250 reference counts in some error exit cases. 1251 1252- SF bug #1185883: Python's small-object memory allocator took over 1253 a block managed by the platform C library whenever a realloc specified 1254 a small new size. However, there's no portable way to know then how 1255 much of the address space following the pointer is valid, so there's no 1256 portable way to copy data from the C-managed block into Python's 1257 small-object space without risking a memory fault. Python's small-object 1258 realloc now leaves such blocks under the control of the platform C 1259 realloc. 1260 1261- SF bug #1232517: An overflow error was not detected properly when 1262 attempting to convert a large float to an int in os.utime(). 1263 1264- SF bug #1224347: hex longs now print with lowercase letters just 1265 like their int counterparts. 1266 1267- SF bug #1163563: the original fix for bug #1010677 ("thread Module 1268 Breaks PyGILState_Ensure()") broke badly in the case of multiple 1269 interpreter states; back out that fix and do a better job (see 1270 http://mail.python.org/pipermail/python-dev/2005-June/054258.html 1271 for a longer write-up of the problem). 1272 1273- SF patch #1180995: marshal now uses a binary format by default when 1274 serializing floats. 1275 1276- SF patch #1181301: on platforms that appear to use IEEE 754 floats, 1277 the routines that promise to produce IEEE 754 binary representations 1278 of floats now simply copy bytes around. 1279 1280- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP 1281 278. 1282 1283- patch #1109424: int, long, float, complex, and unicode now check for the 1284 proper magic slot for type conversions when subclassed. Previously the 1285 magic slot was ignored during conversion. Semantics now match the way 1286 subclasses of str always behaved. int/long/float, conversion of an instance 1287 to the base class has been moved to the proper nb_* magic slot and out of 1288 PyNumber_*(). 1289 Thanks Walter D�rwald. 1290 1291- Descriptors defined in C with a PyGetSetDef structure, where the setter is 1292 NULL, now raise an AttributeError when attempting to set or delete the 1293 attribute. Previously a TypeError was raised, but this was inconsistent 1294 with the equivalent pure-Python implementation. 1295 1296- It is now safe to call PyGILState_Release() before 1297 PyEval_InitThreads() (note that if there is reason to believe there 1298 are multiple threads around you still must call PyEval_InitThreads() 1299 before using the Python API; this fix is for extension modules that 1300 have no way of knowing if Python is multi-threaded yet). 1301 1302- Typing Ctrl-C whilst raw_input() was waiting in a build with threads 1303 disabled caused a crash. 1304 1305- Bug #1165306: instancemethod_new allowed the creation of a method 1306 with im_class == im_self == NULL, which caused a crash when called. 1307 1308- Move exception finalisation later in the shutdown process - this 1309 fixes the crash seen in bug #1165761 1310 1311- Added two new builtins, any() and all(). 1312 1313- Defining a class with empty parentheses is now allowed 1314 (e.g., ``class C(): pass`` is no longer a syntax error). 1315 Patch #1176012 added support to the 'parser' module and 'compiler' package 1316 (thanks to logistix for that added support). 1317 1318- Patch #1115086: Support PY_LONGLONG in structmember. 1319 1320- Bug #115…
