Guido van Rossumc69ac252006-08-10 18:09:25 +0000905What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000909
910Core and builtins
911-----------------
912
Neal Norwitz24b6f202006-09-05 04:43:56 +0000913- Fix infinite recursion when subclassing long and overriding __hash__.
914
915- Fix concatenation (+=) of long strings.
916
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000917- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000918 compared equal or unequal to a string and a UnicodeDecodeError
919 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000920
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000921 Instead, the equal (==) and unequal (!=) comparison operators will
922 now issue a UnicodeWarning and interpret the two objects as
923 unequal. The UnicodeWarning can be filtered as desired using
924 the warning framework, e.g. silenced completely, turned into an
925 exception, logged, etc.
926
927 Note that compare operators other than equal and unequal will still
928 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000929
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000930- Fix segfault when doing string formatting on subclasses of long.
931
932- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
933 with new-style classes.
934
935- Fix bug related to __len__ functions returning negative values with
936 classic classes.
937
938- Patch #1538606, Fix __index__() clipping. There were some problems
939 discovered with the API and how integers that didn't fit into Py_ssize_t
940 were handled. This patch attempts to provide enough alternatives
941 to effectively use __index__.
942
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000943- Bug #1536021: __hash__ may now return long int; the final hash
944 value is obtained by invoking hash on the long int.
945
Thomas Hellerab1049c2006-08-08 17:37:00 +0000946- Bug #1536786: buffer comparison could emit a RuntimeWarning.
947
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000948- Bug #1535165: fixed a segfault in input() and raw_input() when
949 sys.stdin is closed.
950
Thomas Heller74d36f02006-08-04 18:17:40 +0000951- On Windows, the PyErr_Warn function is now exported from
952 the Python dll again.
953
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000954- Bug #1191458: tracing over for loops now produces a line event
955 on each iteration. Fixing this problem required changing the .pyc
956 magic number. This means that .pyc files generated before 2.5c1
957 will be regenerated.
958
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000959- Bug #1333982: string/number constants were inappropriately stored
960 in the byte code and co_consts even if they were not used, ie
961 immediately popped off the stack.
962
Georg Brandle9462c72006-08-04 18:03:37 +0000963- Fixed a reference-counting problem in property().
964
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000965
966Library
967-------
968
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000969- Fix a bug in the ``compiler`` package that caused invalid code to be
970 generated for generator expressions.
971
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000972- The distutils version has been changed to 2.5.0. The change to
973 keep it programmatically in sync with the Python version running
974 the code (introduced in 2.5b3) has been reverted. It will continue
975 to be maintained manually as static string literal.
976
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000977- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000978 and this cannot be converted to the required C type, an exception is
979 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000980 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000981
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000982- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000983 an exception.
984
Tim Peterscbdd3502006-09-05 01:47:53 +0000985- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000986 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000987 workarounds for clocks with low resolution, to stop the code yielding
988 duplicate UUIDs.
989
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000990- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
991 before raising SystemExit, allowing IDLE to honor quit() and exit().
992
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000993- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
994
Georg Brandl7a1af772006-08-14 21:55:28 +0000995- Patch #1536071: trace.py should now find the full module name of a
996 file correctly even on Windows.
997
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000998- logging's atexit hook now runs even if the rest of the module has
999 already been cleaned up.
1000
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001001- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001002
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001003- Bug #1531405, format_exception no longer raises an exception if
1004 str(exception) raised an exception.
1005
Neil Schemenauer06ded092006-08-04 16:20:30 +00001006- Fix a bug in the ``compiler`` package that caused invalid code to be
1007 generated for nested functions.
1008
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001009
1010Extension Modules

1016
Georg Brandl3335a7a2006-08-14 21:42:55 +00001017- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1018 raises the correct exceptions.
1019
Thomas Heller1ce433e2006-08-14 16:20:04 +00001020- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1021 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1022
Thomas Heller86720042006-08-14 11:17:48 +00001023- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1024 uses the _as_parameter_ attribute when objects are passed to foreign
1025 function calls. The ctypes version number was changed to 1.0.1.
1026
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001027- Bug #1530559, struct.pack raises TypeError where it used to convert.
1028 Passing float arguments to struct.pack when integers are expected
1029 now triggers a DeprecationWarning.
1030
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001031

1054
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001055- Bug #1535502, build _hashlib on Windows, and use masm assembler
1056 code in OpenSSL.
1057
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001058- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001060- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001061
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001062
Tim Peters4643c2f2006-08-10 22:45:34 +00001063C API
1064-----
1065
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001066- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1067
Tim Peters4643c2f2006-08-10 22:45:34 +00001068- Bug #1069160. Internal correctness changes were made to
1069 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1070 the documentation was changed to state that the return value
1071 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001074What's New in Python 2.5 beta 3?
1075================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001076
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001077*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001078
1079Core and builtins
1080-----------------
1081
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001082- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001083 returned a long (see PEP 353).
1084
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001085- Bug #1515471: string.replace() accepts character buffers again.
1086
Neal Norwitz07aadb12006-07-30 06:55:48 +00001087- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1088 This provides the proper warning for struct.pack().
1089 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1090
Neal Norwitz0d62a062006-07-30 06:53:31 +00001091- Patch #1531113: Fix augmented assignment with yield expressions.
1092 Also fix a SystemError when trying to assign to yield expressions.
1093
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001094- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1095 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1096 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1097 excessive filesystem operations during imports.
1098
Tim Petersbc24eee2006-07-27 01:14:53 +00001099- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1100 operations on signed longs that are formally undefined by C.
1101 Unfortunately, at least one compiler now cares about that, so complicated
1102 the code to make that compiler happy again.
1103
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001104- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1105
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001106- Patch #1232023: Stop including current directory in search
1107 path on Windows.
1108
Neal Norwitze1fdb322006-07-21 05:32:28 +00001109- Fix some potential crashes found with failmalloc.
1110
Neal Norwitze7563102006-07-17 01:00:16 +00001111- Fix warnings reported by Klocwork's static analysis tool.
1112
Neal Norwitz84be93b2006-07-16 01:50:38 +00001113- Bug #1512814, Fix incorrect lineno's when code within a function
1114 had more than 255 blank lines.
1115
Georg Brandl9dceedb2006-07-12 15:31:17 +00001116- Patch #1521179: Python now accepts the standard options ``--help`` and
1117 ``--version`` as well as ``/?`` on Windows.
1118
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001119- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001120 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001121 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001122
Tim Peters112aad32006-07-19 00:03:19 +00001123- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001124 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001125 new ``sys._current_frames()`` returns a dictionary with one entry,
1126 mapping the faux "thread id" 0 to the current frame.
1127
Ronald Oussoren3075e162006-07-25 20:28:55 +00001128- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001129
Ronald Oussoren3075e162006-07-25 20:28:55 +00001130
Neal Norwitza1f10902006-07-12 07:28:29 +00001131Library
1132-------
1133
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001134- Correction of patch #1455898: In the mbcs decoder, set final=False
1135 for stream decoder, but final=True for the decode function.
1136
Georg Brandl07fec3a2006-08-01 18:49:24 +00001137- os.urandom no longer masks unrelated exceptions like SystemExit or
1138 KeyboardInterrupt.
1139
Tim Peters4643c2f2006-08-10 22:45:34 +00001140- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001141 shutil.copytree on Windows
1142
Georg Brandle34ac7c2006-07-30 11:07:23 +00001143- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1144 refers to file descriptors, not file objects.
1145
Tim Peterscbdd3502006-09-05 01:47:53 +00001146- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001147 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001148 #1513611, and probably others.
1149
Georg Brandledd9b0d2006-07-29 09:33:26 +00001150- Bug #1441397: The compiler module now recognizes module and function
1151 docstrings correctly as it did in Python 2.4.
1152
Tim Peters6f681472006-07-27 23:44:37 +00001153- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1154 lost that tests are sorted by name before being run. This rarely
1155 matters for well-written tests, but can create baffling symptoms if
1156 side effects from one test to the next affect outcomes. ``DocTestFinder``
1157 has been changed to sort the list of tests it returns.
1158
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001159- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001160 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001161
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001162- Bug #978833: Really close underlying socket in _socketobject.close.
1163
Georg Brandldb232dc2006-08-20 13:15:43 +00001164- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1165 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001166
Georg Brandlcf0c1722006-07-26 07:23:32 +00001167- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1168 to recursive calls and call it with the failing package name.

Martin v. Löwis0b483032006-07-25 09:53:12 +00001170- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1171
Georg Brandlc13c34c2006-07-24 14:09:56 +00001172- Patch #1515343: Fix printing of deprecated string exceptions with a
1173 value in the traceback module.
1174
Greg Ward48fae7a2006-07-23 16:05:51 +00001175- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1176
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001177- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1178
Brett Cannoncaebe222006-07-18 04:41:36 +00001179- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1180 argument tuple. For arguments where zero is illegal, the value is forced to
1181 the minimum value that is correct. This is to support an undocumented but
1182 common way people used to fill in inconsequential information in the time
1183 tuple pre-2.4.
1184
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001185- Patch #1220874: Update the binhex module for Mach-O.
1186
Barry Warsawb110bad2006-07-21 14:51:07 +00001187- The email package has improved RFC 2231 support, specifically for
1188 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1189 (name*0=<blah>) parameter continuations. This may change the types of
1190 values returned from email.message.Message.get_param() and friends.
1191 Specifically in some cases where non-encoded continuations were used,
1192 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1193 will just return the string (since non-encoded continuations don't have
1194 charset and language parts).
1195
1196 Also, whereas % values were decoded in all parameter continuations, they are
1197 now only decoded in encoded parameter parts.
1198
Ronald Oussoren3075e162006-07-25 20:28:55 +00001199- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1200
1201- Bug #1517996: IDLE now longer shows the default Tk menu when a
1202 path browser, class browser or debugger is the frontmost window on MacOS X
1203
Barry Warsaw00decd72006-07-27 23:43:15 +00001204- Patch #1520294: Support for getset and member descriptors in types.py,
1205 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1206 of an object against these built-in types and more importantly, for getting
1207 their docstrings printed in the interactive interpreter's help() function.

1211-----------------
1212
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001213- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1214 a socket operation on a socket with a timeout, the exception will be
1215 caught correctly. Previously, the exception was not caught.
1216
Thomas Heller1393d6a2006-07-28 21:43:20 +00001217- Patch #1529514: The _ctypes extension is now compiled on more
1218 openbsd target platforms.
1219
Tim Peters9cab5932006-07-28 00:30:00 +00001220- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1221 a memory leak, affecting pickles and deep copies.
1222
Tim Petersbc24eee2006-07-27 01:14:53 +00001223- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1227
Thomas Hellerce049a02006-07-14 17:51:14 +00001228- Patch #1521817: Index range checking on ctypes arrays containing
1229 exactly one element enabled again. This allows iterating over these
1230 arrays, without the need to check the array size before.
1231
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001232- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001233 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001234 /dev/null in certain cases; this is now fixed.
1235
Thomas Heller47d7a062006-07-12 08:43:47 +00001236- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1237 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001238
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001239- Because of a misspelled preprocessor symbol, ctypes was always
1240 compiled without thread support; this is now fixed.
1241
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001242- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1243 methods now allow their database parameter to be None as the
1244 sleepycat API allows.
1245
Matt Flemingec926502006-07-28 11:27:27 +00001246- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1247 bluetooth API compared with Linux and FreeBSD.
1248
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001249Tests
1250-----
1251
1252- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1253 how long the test file should take to play. Now accepts taking 2.93 secs
1254 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1255
Georg Brandl4793aa32006-07-28 18:31:39 +00001256- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1257 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1258 run via ``regrtest.py``. Now they do.

1263- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1264
Ronald Oussoren26cad082006-08-01 21:00:57 +00001265Mac
1266---
1267
1268- PythonLauncher now works correctly when the path to the script contains
1269 characters that are treated specially by the shell (such as quotes).
1270
1271- Bug #1527397: PythonLauncher now launches scripts with the working directory
1272 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001273 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001274 expect.

1283-----------------
1284
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001285- Bug #1441486: The literal representation of -(sys.maxint - 1)
1286 again evaluates to a int object, not a long.
1287
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001288- Bug #1501934: The scope of global variables that are locally assigned
1289 using augmented assignment is now correctly determined.
1290
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001291- Bug #927248: Recursive method-wrapper objects can now safely
1292 be released.
1293
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001294- Bug #1417699: Reject locale-specific decimal point in float()
1295 and atof().
1296
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001297- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1298 omit a default "error" argument for NULL pointer. This allows
1299 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001300
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001301- Bug #1519018: 'as' is now validated properly in import statements.
1302
Neal Norwitz28746ab2006-07-09 22:14:42 +00001303- On 64 bit systems, int literals that use less than 64 bits are
1304 now ints rather than longs.
1305
Neal Norwitzed657552006-07-10 00:04:44 +00001306- Bug #1512814, Fix incorrect lineno's when code at module scope
1307 started after line 256.
1308
Tim Peters32a83612006-07-10 21:08:24 +00001309- New function ``sys._current_frames()`` returns a dict mapping thread
1310 id to topmost thread stack frame. This is for expert use, and is
1311 especially useful for debugging application deadlocks. The functionality
1312 was previously available in Fazal Majid's ``threadframe`` extension
1313 module, but it wasn't possible to do this in a wholly threadsafe way from
1314 an extension.
1315

1331
Thomas Woutersadd19112006-07-05 11:03:49 +00001332- string.Template() now correctly handles tuple-values. Previously,
1333 multi-value tuples would raise an exception and single-value tuples would
1334 be treated as the value they contain, instead.
1335
Martin v. Löwisede77f52006-07-03 13:01:35 +00001336- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1343 degrees and radians.
1344
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001345- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001346 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001347

1349 is created.
1350
Martin v. Löwis7596e832006-07-01 15:33:37 +00001351- Bug #1513223: .close() of a _socketobj now releases the underlying
1352 socket again, which then gets closed as it becomes unreferenced.

1357- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1358 sgmllib ('[' and ']' were not accepted).
1359
Georg Brandl1be63af2006-06-28 20:23:25 +00001360- Fix a bug in the turtle module's end_fill function.
1361
Brett Cannon53ab5b72006-06-22 16:49:14 +00001362- Bug #1510580: The 'warnings' module improperly required that a Warning
1363 category be either a types.ClassType and a subclass of Warning. The proper
1364 check is just that it is a subclass with Warning as the documentation states.
1365
Georg Brandlad29e632006-06-21 17:45:17 +00001366- The compiler module now correctly compiles the new try-except-finally
1367 statement (bug #1509132).
1368
Neal Norwitz60373cd2006-06-22 06:30:50 +00001369- The wsgiref package is now installed properly on Unix.
1370

1372 shutdown when fileConfig() was called multiple times.
1373
Gerhard Häring762fbd32006-07-02 17:48:30 +00001374- The sqlite3 module did cut off data from the SQLite database at the first
1375 null character before sending it to a custom converter. This has been fixed
1376 now.

1379-----------------
1380
Tim Peters112aad32006-07-19 00:03:19 +00001381- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1382 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1383 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001384
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001385- Assigning None to pointer type fields in ctypes structures possible
1386 overwrote the wrong fields, this is fixed now.
1387
1388- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1389 on non-Windows platforms.
1390
1391- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1392 integer or long, without range checking.
1393
1394- Patch #1517790: It is now possible to use custom objects in the ctypes
1395 foreign function argtypes sequence as long as they provide a from_param
1396 method, no longer is it required that the object is a ctypes type.
1397
1398- The '_ctypes' extension module now works when Python is configured
1399 with the --without-threads option.
1400
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001401- Bug #1513646: os.access on Windows now correctly determines write

1416
Tim Peters32a83612006-07-10 21:08:24 +00001417- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001418 Previously, the slight difference could cause compilation errors of the
1419 'zlib' module on systems with more than one version of zlib.
1420
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001421- The MSI compileall step was fixed to also support a TARGETDIR

1458
Brett Cannonea3912b2006-06-13 21:46:41 +00001459- Bug #992017: A classic class that defined a __coerce__() method that returned
1460 its arguments swapped would infinitely recurse and segfault the interpreter.
1461
Neal Norwitz909eb122006-06-12 02:13:21 +00001462- Fix the socket tests so they can be run concurrently.

Brett Cannon22565aa2006-06-09 22:31:23 +00001467- Bug #532646: object.__call__() will continue looking for the __call__
1468 attribute on objects until one without one is found. This leads to recursion
1469 when you take a class and set its __call__ attribute to an instance of the
1470 class. Originally fixed for classic classes, but this fix is for new-style.
1471 Removes the infinite_rec_3 crasher.
1472
Georg Brandl24250812006-06-09 18:45:48 +00001473- The string and unicode methods startswith() and endswith() now accept
1474 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1475
Brett Cannonde3b0522006-06-08 17:00:45 +00001476- Buffer objects, at the C level, never used the char buffer
1477 implementation even when the char buffer for the wrapped object was
1478 explicitly requested (originally returned the read or write buffer).
1479 Now a TypeError is raised if the char buffer is not present but is
1480 requested.
1481
Georg Brandlddbaa662006-06-04 21:56:52 +00001482- Patch #1346214: Statements like "if 0: suite" are now again optimized
1483 away like they were in Python 2.4.
1484
Georg Brandlb7c8f542006-05-27 12:30:25 +00001485- Builtin exceptions are now full-blown new-style classes instead of
1486 instances pretending to be classes, which speeds up exception handling
1487 by about 80% in comparison to 2.5a2.
1488
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001489- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1490 Unicode 4.1.
1491
Georg Brandlf4ef1162006-05-26 18:03:31 +00001492- Patch #921466: sys.path_importer_cache is now used to cache valid and
1493 invalid file paths for the built-in import machinery which leads to
1494 fewer open calls on startup.
1495
Tim Peters696cf432006-05-24 21:10:40 +00001496- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1497 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1498 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1499 the number of input digits (it was and remains linear-time for bases
1500 2, 4, 8, 16 and 32).
1501
Tim Petersb713ec22006-05-23 18:45:30 +00001502- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1503 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1504 an integer close to ``sys.maxint``. This was repaired by patch
1505 #1335972, which also gives a nice speedup.
1506
Richard Jonescebbefc2006-05-23 18:28:17 +00001507- Patch #1337051: reduced size of frame objects.
1508
1509- PyErr_NewException now accepts a tuple of base classes as its
1510 "base" parameter.
1511
Richard Jones7c88dcc2006-05-23 10:37:38 +00001512- Patch #876206: function call speedup by retaining allocated frame
1513 objects.
1514
Georg Brandl7b90e162006-05-18 07:01:27 +00001515- Bug #1462152: file() now checks more thoroughly for invalid mode
1516 strings and removes a possible "U" before passing the mode to the
1517 C library function.
1518
Neal Norwitz1004a532006-05-15 07:17:23 +00001519- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1520
Neal Norwitz373f0a72006-05-15 07:04:36 +00001521- Bug #1487966: Fix SystemError with conditional expression in assignment
1522
Martin v. Löwis879768d2006-05-11 13:28:43 +00001523- WindowsError now has two error code attributes: errno, which carries
1524 the error values from errno.h, and winerror, which carries the error
1525 values from winerror.h. Previous versions put the winerror.h values
1526 (from GetLastError()) into the errno attribute.
1527
Martin v. Löwis77736712006-05-04 05:51:03 +00001528- Patch #1475845: Raise IndentationError for unexpected indent.
1529
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001530- Patch #1479181: split open() and file() from being aliases for each other.
1531
Tim Peters44bd9862006-06-01 13:49:23 +00001532- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1533 methods were always silently ignored by dictionaries when comparing keys.
1534 They are now passed through (except when using the C API function
1535 ``PyDict_GetItem()``, whose semantics did not change).
1536
1537- Bug #1456209: In some obscure cases it was possible for a class with a
1538 custom ``__eq__()`` method to confuse dict internals when class instances
1539 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1540 No, you don't have any code that did this ;-)

1543-----------------
1544
Trent Mick960a3f82006-06-28 20:30:41 +00001545- Bug #1295808: expat symbols should be namespaced in pyexpat
1546
1547- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1548
Brett Cannon6ee7d012006-06-08 16:23:04 +00001549- Change binascii.hexlify to accept a read-only buffer instead of only a char
1550 buffer and actually follow its documentation.
1551
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001552- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1553
Nick Coghlanc649ec52006-05-29 12:43:05 +00001554- Patch #1478788 (modified version): The functional extension module has
1555 been renamed to _functools and a functools Python wrapper module added.
1556 This provides a home for additional function related utilities that are
1557 not specifically about functional programming. See PEP 309.
1558
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001559- Patch #1493701: performance enhancements for struct module.
1560
Georg Brandl378d5922006-05-17 14:26:50 +00001561- Patch #1490224: time.altzone is now set correctly on Cygwin.
1562
Georg Brandl8d3342b2006-05-16 07:38:27 +00001563- Patch #1435422: zlib's compress and decompress objects now have a
1564 copy() method.
1565
Andrew MacIntyre92913322006-06-13 15:04:24 +00001566- Patch #1454481: thread stack size is now tunable at runtime for thread
1567 enabled builds on Windows and systems with Posix threads support.
1568
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001569- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1570 (up to the system limit of 32K characters).
1571
1572- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1573 As a result, these functions now raise WindowsError instead of OSError.
1574
Tim Peters7a822da2006-05-25 21:50:17 +00001575- ``time.clock()`` on Win64 should use the high-performance Windows
1576 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1577 Windows platforms).
1578
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001579- Calling Tk_Init twice is refused if the first call failed as that
1580 may deadlock.
1581
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001582- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1583 accept it without potentially using an uninitialized pointer.
1584
1585- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1586 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1587 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001588
Gregory P. Smith372b5832006-06-05 18:48:21 +00001589- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001590 [pybsddb project SF patch number 1466734]
1591
Gregory P. Smith372b5832006-06-05 18:48:21 +00001592- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1593 parameter is supplied. [SF pybsddb bug #1477863]
1594
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001595- bsddb: the __len__ method of a DB object has been fixed to return correct
1596 results. It could previously incorrectly return 0 in some cases.
1597 Fixes SF bug 1493322 (pybsddb bug 1184012).
1598
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001599- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1600 aborts the db transaction safely when a modifier callback fails.
1601 Fixes SF python patch/bug #1408584.
1602
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001603- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001604 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001605 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1606 database calls that would previously deadlock. [SF python bug #775414]
1607
Vinay Sajip28e57612006-07-01 10:45:20 +00001608- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001616- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1617 functions.
1618
Martin v. Löwis3798da02006-06-17 18:44:27 +00001619- Patch #812986: Update turtle output even if not tracing.
1620
Vinay Sajip28e57612006-07-01 10:45:20 +00001621- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001622 Tkinter.BaseWidget.
1623
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001624- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1625
Martin v. Löwis337487e2006-06-17 09:15:14 +00001626- Patch #763580: Add name and value arguments to Tkinter variable
1627 classes.
1628
Georg Brandl83cc0d02006-06-14 08:50:03 +00001629- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1630 mime.types file for determining MIME types.
1631
Georg Brandl2605ca82006-06-14 06:08:31 +00001632- Bug #1339007: Shelf objects now don't raise an exception in their
1633 __del__ method when initialization failed.
1634
Martin v. Löwisd8251432006-06-14 05:21:04 +00001635- Patch #1455898: The MBCS codec now supports the incremental mode for
1636 double-byte encodings.
1637
Tim Peters43898b42006-06-14 04:09:25 +00001638- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1639 guarantee that adjacent triples in the return list always describe
1640 non-adjacent blocks. Previously, a pair of matching blocks could end
1641 up being described by multiple adjacent triples that formed a partition
1642 of the matching pair.
1643
Greg Ward0e0c9f42006-06-11 16:24:11 +00001644- Bug #1498146: fix optparse to handle Unicode strings in option help,
1645 description, and epilog.
1646
Greg Wardd1c797e2006-06-11 14:42:41 +00001647- Bug #1366250: minor optparse documentation error.
1648
Greg Ward7f547402006-06-11 00:40:49 +00001649- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1650 clarify docs.
1651
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001652- The wsgiref package has been added to the standard library.
1653
Nick Coghlan676725d2006-06-08 13:54:49 +00001654- The functions update_wrapper() and wraps() have been added to the functools
1655 module. These make it easier to copy relevant metadata from the original
1656 function when writing wrapper functions.
1657
Tim Petersd6a9eef2006-06-05 01:48:21 +00001658- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1659 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001660
Martin v. Löwis3f767792006-06-04 19:36:28 +00001661- Patch #1359618: Speed up charmap encoder by using a trie structure
1662 for lookup.
1663
Tim Petersd609b1a2006-06-02 23:22:51 +00001664- The functions in the ``pprint`` module now sort dictionaries by key
1665 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1666 if and only if its display required more than one line, although that
1667 wasn't documented. The new behavior increases predictability; e.g.,
1668 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1669
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001670- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1671 (thanks for J. J. Lee).
1672
Georg Brandl2b330372006-05-28 20:23:12 +00001673- Patch #1496206: improve urllib2 handling of passwords with respect to
1674 default HTTP and HTTPS ports.
1675
George Yoshidaf3c65de2006-05-28 16:39:09 +00001676- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1677
Bob Ippolito7298f272006-05-23 18:43:47 +00001678- Patch #1281707: speed up gzip.readline.
1679
Georg Brandlb89316f2006-05-17 15:51:16 +00001680- Patch #1180296: Two new functions were added to the locale module:
1681 format_string() to get the effect of "format % items" but locale-aware,
1682 and currency() to format a monetary number with currency sign.
1683
Georg Brandle3a25832006-05-17 14:56:04 +00001684- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1685 and several features added, such as speed and geometry control.
1686
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001687- Patch #1488881: add support for external file objects in bz2 compressed
1688 tarfiles.
1689
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001690- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1691 stdout arguments, making it possible to redirect input and output
1692 for remote debugging.
1693
1694- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1695 a couple of issues, notably handling of long file names using the
1696 GNU LONGNAME extension.
1697
1698- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1699 new flag when ``name`` is already the name of an option flag.
1700
1701- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1702 package.
1703
1704- Patch #1472854: make the rlcompleter.Completer class usable on non-
1705 UNIX platforms.
1706
1707- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1708
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001709- Bug #1472827: correctly escape newlines and tabs in attribute values in

1745Core and builtins
1746-----------------
1747
Thomas Heller1b046642006-04-18 18:51:06 +00001748- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1749 by converting these apis from macros into exported functions again:
1750
1751 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1752 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1753 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1755 PyRun_String Py_CompileString
1756
Martin v. Löwis45294a92006-04-18 06:24:08 +00001757- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1758
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001759- All uses of PyStructSequence_InitType have been changed to initialize
1760 the type objects only once, even if the interpreter is initialized
1761 multiple times.
1762
Neal Norwitz61546162006-04-14 05:20:28 +00001763- Bug #1454485, array.array('u') could crash the interpreter. This was
1764 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1765 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1766
1767- Py_UNICODE is unsigned. It was always documented as unsigned, but
1768 due to a bug had a signed value in previous versions.
1769
Tim Peters3a5e8b12006-04-11 01:44:07 +00001770- Patch #837242: ``id()`` of any Python object always gives a positive
1771 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1772 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001773 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001774 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001775
Tim Peters3a5e8b12006-04-11 01:44:07 +00001776 def __hash__(self):
1777 return id(self) # WRONG
1778
1779 because a hash result must be a (short) Python int but it was always
1780 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001781 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001782 was always usable as a hash value before this patch. That's no longer
1783 necessarily so.
1784
1785- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001786 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001787 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001788 #1454844)
1789
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001790- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1791 involving generators that have paused outside of any ``try`` or ``with``
1792 blocks. (In 2.5a1, a paused generator that was part of a reference
1793 cycle could not be garbage collected, regardless of whether it was
1794 paused in a ``try`` or ``with`` block.)

1803 fails with an error condition.
1804
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001805- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1806
1807- Bug #1117761: bsddb.*open() no longer raises an exception when using
1808 the cachesize parameter.
1809
1810- Bug #1149413: bsddb.*open() no longer raises an exception when using
1811 a temporary db (file=None) with the 'n' flag to truncate on open.
1812
1813- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1814 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001815
Armin Rigoa9017c32006-04-19 11:50:27 +00001816- Patch #1062014: AF_UNIX sockets under Linux have a special

1820-------
1821
Peter Astrand7d1d4362006-07-14 14:04:45 +00001822- Bug #1223937: subprocess.CalledProcessError reports the exit status
1823 of the process using the returncode attribute, instead of
1824 abusing errno.
1825
Tim Peters711bf302006-04-25 03:31:36 +00001826- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1827 a doctest to be skipped (the code is not run, and the expected output
1828 or exception is ignored).
1829
Nick Coghlanda2268f2006-04-24 04:37:15 +00001830- Fixed contextlib.nested to cope with exceptions being raised and
1831 caught inside exit handlers.
1832
Greg Wardab05edc2006-04-23 03:47:58 +00001833- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1834 hex, octal, or binary; add ``append_const`` action; keep going if
1835 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1836 added ``epilog`` for better help generation).
1837
Tim Peters21fbd572006-04-21 21:18:10 +00001838- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1839 called from a thread spawned as a side effect of importing a module.
1840
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001841- The pydoc module now supports documenting packages contained in
1842 .zip or .egg files.
1843
1844- The pkgutil module now has several new utility functions, such
1845 as ``walk_packages()`` to support working with packages that are either
1846 in the filesystem or zip files.
1847
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001848- The mailbox module can now modify and delete messages from
1849 mailboxes, in addition to simply reading them. Thanks to Gregory
1850 K. Johnson for writing the code, and to the 2005 Google Summer of
1851 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001852
Tim Petersc7605f22006-04-17 21:12:33 +00001853- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001862- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1863 Windows. Bug #1469163.
1864
Phillip J. Eby47032112006-04-11 01:07:43 +00001865- The warnings, linecache, inspect, traceback, site, and doctest modules

1875
Skip Montanaro262fb922006-04-21 02:31:07 +00001876- The pstats.Stats class accepts an optional stream keyword argument to
1877 direct output to an alternate file-like object.
1878
Anthony Baxter51bcb682006-04-05 14:51:42 +00001879Build
1880-----
1881
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001882- The Makefile now has a reindent target, which runs reindent.py on
1883 the library.
1884
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001885- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001888
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001889- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1890 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001891 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001892 CXX from --with-cxx-main, see description in README.
1893
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001894- Patch #1429775: Link extension modules with the shared libpython.
1895
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001896- Fixed a libffi build problem on MIPS systems.
1897
Tim Peters8931ff12006-05-13 23:28:20 +00001898- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1899 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1900 and "%zu" for unsigned integers of type ``size_t``.
1901
Anthony Baxter51bcb682006-04-05 14:51:42 +00001902Tests
1903-----
1904
Nick Coghlanda2268f2006-04-24 04:37:15 +00001905- test_contextlib now checks contextlib.nested can cope with exceptions
1906 being raised and caught inside exit handlers.
1907
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001908- test_cmd_line now checks operation of the -m and -c command switches
1909
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001910- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1911 it separately and by hand. It also wasn't cleaning up its changes to
1912 the current Decimal context.
1913
Thomas Woutersabd08882006-04-26 15:53:30 +00001914- regrtest.py now has a -M option to run tests that test the new limits of
1915 containers, on 64-bit architectures. Running these tests is only sensible
1916 on 64-bit machines with more than two gigabytes of memory. The argument
1917 passed is the maximum amount of memory for the tests to use.

1926-------------
1927
Tim Petersb06d28c2006-05-12 01:57:59 +00001928- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1929
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001930- PEP 343: Added Context Types section to the library reference
1931 and attempted to bring other PEP 343 related documentation into
1932 line with the implementation and/or python-dev discussions.
1933
Tim Peters8dc73d22006-04-24 02:03:16 +00001934- Bug #1337990: clarified that ``doctest`` does not support examples
1935 requiring both expected output and an exception.

1939=================================
1940
Anthony Baxterebed3f62006-04-03 15:03:44 +00001941*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001942
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001943Core and builtins
1944-----------------
1945
Nick Coghlan43832302006-04-23 17:04:07 +00001946- PEP 338: -m command line switch now delegates to runpy.run_module
1947 allowing it to support modules in packages and zipfiles
1948
Martin v. Löwisc661b882006-04-20 04:54:23 +00001949- On Windows, .DLL is not an accepted file name extension for
1950 extension modules anymore; extensions are only found if they
1951 end in .PYD.
1952
Martin v. Löwisea62d252006-04-03 10:56:49 +00001953- Bug #1421664: sys.stderr.encoding is now set to the same value as
1954 sys.stdout.encoding.
1955
Neal Norwitz92e212f2006-04-03 04:48:37 +00001956- __import__ accepts keyword arguments.
1957
Georg Brandlccadf842006-03-31 18:54:53 +00001958- Patch #1460496: round() now accepts keyword arguments.
1959
Anthony Baxter262c00a2006-03-30 10:53:17 +00001960- Fixed bug #1459029 - unicode reprs were double-escaped.
1961
Hye-Shik Changd478f342006-03-23 12:32:36 +00001962- Patch #1396919: The system scope threads are reenabled on FreeBSD
1963 5.4 and later versions.
1964
Neal Norwitze98ccf62006-03-23 05:39:47 +00001965- Bug #1115379: Compiling a Unicode string with an encoding declaration
1966 now gives a SyntaxError.
1967
Georg Brandlabd1ff82006-03-18 07:59:59 +00001968- Previously, Python code had no easy way to access the contents of a
1969 cell object. Now, a ``cell_contents`` attribute has been added
1970 (closes patch #1170323).
1971
Tim Peterscf79aac2006-03-16 01:14:46 +00001972- Patch #1123430: Python's small-object allocator now returns an arena to
1973 the system ``free()`` when all memory within an arena becomes unused
1974 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1975 freed. Some applications will see a drop in virtual memory size now,
1976 especially long-running applications that, from time to time, temporarily
1977 use a large number of small objects. Note that when Python returns an
1978 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001979 platform C library will in turn return that memory to the operating system.
1980 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001981 appears to be effective at least on Microsoft C and gcc-based systems.
1982 Thanks to Evan Jones for hard work and patience.
1983
Georg Brandl533ff6f2006-03-08 18:09:27 +00001984- Patch #1434038: property() now uses the getter's docstring if there is
1985 no "doc" argument given. This makes it possible to legitimately use
1986 property() as a decorator to produce a read-only property.
1987
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001988- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1989 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1990 of requiring an int or long in slicing and a few other contexts, enabling
1991 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1992
Neal Norwitz995acdf2006-03-07 05:01:00 +00001993- Fixed various bugs reported by Coverity's Prevent tool.
1994
Brett Cannonbf364092006-03-01 04:25:17 +00001995- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1996 new exception base class, BaseException, which has a new message attribute.
1997 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1998 Raising a string exception now raises a DeprecationWarning.
1999
Thomas Woutersfb609f42006-02-28 16:37:25 +00002000- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2001 explicitly relative, using 'from .module import name' to mean 'from the same
2002 package as this module is in. Imports without dots still default to the
2003 old relative-then-absolute, unless 'from __future__ import
2004 absolute_import' is used.
2005
Brett Cannona7446e32006-02-27 23:39:10 +00002006- Properly check if 'warnings' raises an exception (usually when a filter set
2007 to "error" is triggered) when raising a warning for raising string
2008 exceptions.
2009
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002010- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002011 The name was removed from Include/code.h.
2012
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002013- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002014
Guido van Rossum1968ad32006-02-25 22:38:04 +00002015- Patch 1433928:
2016 - The copy module now "copies" function objects (as atomic objects).
2017 - dict.__getitem__ now looks for a __missing__ hook before raising
2018 KeyError.
2019
Tim Peters84ef21c2006-02-28 20:39:06 +00002020- PEP 343: with statement implemented. Needs ``from __future__ import
2021 with_statement``. Use of 'with' as a variable will generate a warning.
2022 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002023 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002024 The following objects have __context__ methods:
2025 - The built-in file type.
2026 - The thread.LockType type.
2027 - The following types defined by the threading module:
2028 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2029 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002030
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002031- Fix the encodings package codec search function to only search
2032 inside its own package. Fixes problem reported in patch #1433198.
2033
2034 Note: Codec packages should implement and register their own
2035 codec search function. PEP 100 has the details.
2036
Tim Peters9ea89d22006-06-04 03:26:02 +00002037- PEP 353: Using ``Py_ssize_t`` as the index type.
2038
2039- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2040 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2041 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2042 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2043 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002044
Neal Norwitzfc76d632006-01-10 06:03:13 +00002045- Patch #1400181, fix unicode string formatting to not use the locale.
2046 This is how string objects work. u'%f' could use , instead of .
2047 for the decimal point. Now both strings and unicode always use periods.
2048
Neal Norwitz671b9e32006-01-09 07:07:12 +00002049- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2050 configure would break checking curses.h.
2051
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002052- Bug #959576: The pwd module is now builtin. This allows Python to be
2053 built on UNIX platforms without $HOME set.
2054
Neal Norwitzc10978f2005-12-19 06:07:16 +00002055- Bug #1072182, fix some potential problems if characters are signed.
2056
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002057- Bug #889500, fix line number on SyntaxWarning for global declarations.
2058
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002059- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.

Neal Norwitze7214a12005-12-18 05:03:17 +00002061- Support for converting hex strings to floats no longer works.
2062 This was not portable. float('0x3') now raises a ValueError.
2063
Barry Warsaw2a38a862005-12-18 01:27:35 +00002064- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002065 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002066 is now displayed in interactive prompt banner.
2067
Georg Brandlfa166682005-12-17 21:45:17 +00002068- Implementation of PEP 341 - Unification of try/except and try/finally.
2069 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002070 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002071
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002072- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2073 now encodes backslash correctly.
2074
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002075- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2076
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002077- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002078 and long longs.
2079
Neal Norwitz67715f02005-11-09 06:59:35 +00002080- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002081 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002082 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002083
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002084- Replaced most Unicode charmap codecs with new ones using the
2085 new Unicode translate string feature in the builtin charmap
2086 codec; the codecs were created from the mapping tables available
2087 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2088 encodings now include a mapping for the Apple logo)
2089
Tim Peterse3547fd2005-12-16 23:13:57 +00002090- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002091
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002092- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002093
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002094- A new AST parser implementation was completed. The abstract
2095 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002096 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002097
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002098- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002099 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2100
Neal Norwitz708e51a2005-10-03 04:48:15 +00002101- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2102
Neal Norwitz11bd1192005-10-03 00:54:56 +00002103- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2104 Provide a warning when a directory is passed on the command line.
2105
Neal Norwitz40d37812005-10-02 01:48:49 +00002106- Fix segfault with invalid coding.
2107
2108- SF bug #772896: unknown encoding results in MemoryError.
2109
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002110- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002111 supported a __len__() method which evaluated to False when the iterator
2112 was empty.
2113
Guido van Rossum630db602005-09-20 18:49:54 +00002114- On 64-bit platforms, when __len__() returns a value that cannot be
2115 represented as a C int, raise OverflowError.
2116
Skip Montanarof8948ca2005-09-19 03:54:46 +00002117- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002118 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002119
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002120- SF bug #893549: parsing keyword arguments was broken with a few format
2121 codes.
2122
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002123- Changes donated by Elemental Security to make it work on AIX 5.3
2124 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2125 bug #105470: test_pwd fails on 64bit system (Opteron).
2126
Guido van Rossum539c6622005-09-14 17:49:54 +00002127- Changes donated by Elemental Security to make it work on HP-UX 11 on
2128 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2129
Georg Brandl4550b8d2005-08-26 06:43:52 +00002130- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002131 (fixes bug #1119418).
2132
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002133- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2134
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002135- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2136 exceptions that cause a function to exit.
2137
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002138- The implementation of set() and frozenset() was revised to use its
2139 own internal data structure. Memory consumption is reduced by 1/3
2140 and there are modest speed-ups as well. The API is unchanged.
2141
Tim Petersde7990b2005-07-17 23:45:23 +00002142- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2143
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002144- SF bug #1229429: PyObject_CallMethod failed to decrement some
2145 reference counts in some error exit cases.
2146
Tim Petersecc6e6a2005-07-10 22:30:55 +00002147- SF bug #1185883: Python's small-object memory allocator took over
2148 a block managed by the platform C library whenever a realloc specified
2149 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002150 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002151 portable way to copy data from the C-managed block into Python's
2152 small-object space without risking a memory fault. Python's small-object
2153 realloc now leaves such blocks under the control of the platform C
2154 realloc.
2155
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002156- SF bug #1232517: An overflow error was not detected properly when
2157 attempting to convert a large float to an int in os.utime().
2158
Raymond Hettinger3296e692005-06-29 23:29:56 +00002159- SF bug #1224347: hex longs now print with lowercase letters just
2160 like their int counterparts.
2161
Michael W. Hudson188d4362005-06-20 16:52:57 +00002162- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2163 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2164 interpreter states; back out that fix and do a better job (see
2165 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2166 for a longer write-up of the problem).
2167
Michael W. Hudsondf888462005-06-03 14:41:55 +00002168- SF patch #1180995: marshal now uses a binary format by default when
2169 serializing floats.
2170
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002171- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2172 the routines that promise to produce IEEE 754 binary representations
2173 of floats now simply copy bytes around.
2174
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002175- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2176 278.
2177
Brett Cannonc3647ac2005-04-26 03:45:26 +00002178- patch #1109424: int, long, float, complex, and unicode now check for the
2179 proper magic slot for type conversions when subclassed. Previously the
2180 magic slot was ignored during conversion. Semantics now match the way
2181 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002182 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002183 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002184 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002185
Barry Warsawc8d907c2005-04-19 23:43:40 +00002186- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2187 NULL, now raise an AttributeError when attempting to set or delete the
2188 attribute. Previously a TypeError was raised, but this was inconsistent
2189 with the equivalent pure-Python implementation.
2190
Michael W. Hudson774479c2005-04-18 08:46:17 +00002191- It is now safe to call PyGILState_Release() before
2192 PyEval_InitThreads() (note that if there is reason to believe there
2193 are multiple threads around you still must call PyEval_InitThreads()
2194 before using the Python API; this fix is for extension modules that
2195 have no way of knowing if Python is multi-threaded yet).
2196
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002197- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2198 disabled caused a crash.
2199
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002200- Bug #1165306: instancemethod_new allowed the creation of a method
2201 with im_class == im_self == NULL, which caused a crash when called.
2202
Tim Petersecc6e6a2005-07-10 22:30:55 +00002203- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002204 fixes the crash seen in bug #1165761
2205
Raymond Hettinger96229b12005-03-11 06:49:40 +00002206- Added two new builtins, any() and all().
2207
Brett Cannon409d8f22005-03-05 06:47:57 +00002208- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002209 (e.g., ``class C(): pass`` is no longer a syntax error).
2210 Patch #1176012 added support to the 'parser' module and 'compiler' package
2211 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002212
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002213- Patch #1115086: Support PY_LONGLONG in structmember.
2214
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002215- Bug #1155938: new style classes did not check that __init__() was
2216 returning None.
2217
Tim Petersecc6e6a2005-07-10 22:30:55 +00002218- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002219 ('\') with a specific error message.
2220
Martin v. Löwisff232d72005-03-03 09:24:38 +00002221- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2222
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002223- Bug #1124295: the __name__ attribute of file objects was
2224 inadvertently made inaccessible in restricted mode.
2225
Tim Petersecc6e6a2005-07-10 22:30:55 +00002226- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002227 an ferror() call.
2228
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002229- min() and max() now support key= arguments with the same meaning as in
2230 list.sort().
2231
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002232- The peephole optimizer now performs simple constant folding in expressions:
2233 (2+3) --> (5).
2234
Raymond Hettingera422c342005-01-11 03:03:27 +00002235- set and frozenset objects can now be marshalled. SF #1098985.
2236
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002237- Bug #1077106: Poor argument checking could cause memory corruption
2238 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002239
Jeremy Hyltonab630502005-02-04 18:44:06 +00002240- The parser did not complain about future statements in illegal
2241 positions. It once again reports a syntax error if a future
2242 statement occurs after anything other than a doc string.
2243
Neil Schemenauercf52c072005-08-12 17:34:58 +00002244- Change the %s format specifier for str objects so that it returns a
2245 unicode instance if the argument is not an instance of basestring and
2246 calling __str__ on the argument returns a unicode instance.
2247
Tim Petersf4e69282006-02-27 17:15:31 +00002248- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2249 current thread state when the auto-GIL-state machinery knows about
2250 it (since the thread state is being deleted, continuing to remember it
2251 can't help, but can hurt if another thread happens to get created with
2252 the same thread id).
2253
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002254Extension Modules
2255-----------------
2256
Georg Brandl43f08a82006-03-31 18:01:16 +00002257- Patch #1380952: fix SSL objects timing out on consecutive read()s

2260
Anthony Baxterfa869072006-03-20 05:21:58 +00002261- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2262 In addition, the existing ulaw code was updated.
2263
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002264- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002265 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002266
Neal Norwitz10be10c2006-03-16 06:50:13 +00002267- Everything under lib-old was removed. This includes the following modules:
2268 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002269 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002270 util, whatsound, whrandom, zmod
2271
2272- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2273
2274- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002275 is deprecated. The undocumented re.engine variable no longer exists.
2276
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002277- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2278 SS2 (single-shift 2) escape sequences correctly.
2279
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002280- The unicodedata module was updated to the 4.1 version of the Unicode
2281 database. The 3.2 version is still available as unicodedata.db_3_2_0
2282 for applications that require this specific version (such as IDNA).
2283
Neal Norwitzb62c4332006-03-04 18:35:47 +00002284- The timing module is no longer built by default. It was deprecated
2285 in PEP 4 in Python 2.0 or earlier.
2286
Guido van Rossum1968ad32006-02-25 22:38:04 +00002287- Patch 1433928: Added a new type, defaultdict, to the collections module.
2288 This uses the new __missing__ hook behavior added to dict (see above).
2289
Georg Brandldbd83392006-02-20 09:42:33 +00002290- Bug #854823: socketmodule now builds on Sun platforms even when
2291 INET_ADDRSTRLEN is not defined.
2292
Georg Brandlf4f44152006-02-18 22:29:33 +00002293- Patch #1393157: os.startfile() now has an optional argument to specify
2294 a "command verb" to invoke on the file.
2295
Neal Norwitz082b2df2006-02-07 07:04:46 +00002296- Bug #876637, prevent stack corruption when socket descriptor
2297 is larger than FD_SETSIZE.
2298
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002299- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2300 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2301 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2302
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002303- Patch #1422385: The nis module now supports access to domains other
2304 than the system default domain.
2305
Martin v. Löwis14694662006-02-03 12:54:16 +00002306- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2307 are reported, the limit on path name lengths is removed, and stat reports
2308 WindowsError now (instead of OSError).
2309
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002310- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2311
Neal Norwitz62a21122006-01-25 05:21:55 +00002312- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2313 before the env.
2314
Martin v. Löwis11017b12006-01-14 18:12:57 +00002315- Patch #1103116: Basic AF_NETLINK support.
2316
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002317- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)

2445 been renamed to have only a single underscore prefix. This was done to
2446 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002447
Nick Coghlan43832302006-04-23 17:04:07 +00002448- PEP 338: new module runpy defines a run_module function to support
2449 executing modules which provide access to source code or a code object
2450 via the PEP 302 import mechanisms.
2451

2460 in attribute values.
2461
Anthony Baxterc51ee692006-04-01 00:57:31 +00002462- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002463 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002464 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002465 module will not be built.
2466
Tim Petersc17976e2006-04-01 00:26:53 +00002467- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2468 aren't officially supported here, and trying to use them will probably
2469 raise an exception some day. But dicts have been allowed, and "mostly
2470 worked", so support for them won't go away without warning.
2471
Georg Brandl338ef7d2006-03-31 18:42:16 +00002472- Bug #1445068: getpass.getpass() can now be given an explicit stream

2490
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002491- email 4.0 package now integrated. This is largely the same as the email 3.0
2492 package that was included in Python 2.3, except that PEP 8 module names are
2493 now used (e.g. mail.message instead of email.Message). The MIME classes
2494 have been moved to a subpackage (e.g. email.mime.text instead of
2495 email.MIMEText). The old names are still supported for now. Several
2496 deprecated Message methods have been removed and lots of bugs have been
2497 fixed. More details can be found in the email package documentation.
2498
Walter Dörwald40108c92006-03-27 08:15:44 +00002499- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2500 (a subclass of tuple) that provides incremental decoders and encoders
2501 (a way to use stateful codecs without the stream API). Python functions
2502 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2503 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2504 have been added.

2507 a ValueError instead of a StopIteration now (like file and cString.String do).
2508 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2509 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002583 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2584 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2585 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2586 Ronald L. Rivest offered this advice for Python:
2587
2588 "The consensus of researchers in this area (at least as
2589 expressed at the NIST Hash Function Workshop 10/31/05),
2590 is that SHA-256 is a good choice for the time being, but
2591 that research should continue, and other alternatives may
2592 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002593
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002594- Added a subset of Fredrik Lundh's ElementTree package. Available

2647 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002648 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002649

2671 to W3C name (404 -> 'Not Found'). RFE #1216944.
2672
Georg Brandl9e43acf2005-07-04 17:16:07 +00002673- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2674 as this can cause problems with apps closing all file descriptors.

2687 Bug #1224621.
2688
Raymond Hettinger68c04532005-06-10 11:05:19 +00002689- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002690 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002691 the generate_tokens() function now accepts a callable argument that
2692 terminates by raising StopIteration.
2693
Georg Brandl9166e1a2005-06-04 09:20:03 +00002694- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2702 class at all.
2703
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002704- distutils.commands.upload was added to support uploading distribution

2708 them to PyPI.
2709
Raymond Hettinger267b8682005-03-27 10:47:39 +00002710- decimal operator and comparison methods now return NotImplemented
2711 instead of raising a TypeError when interacting with other types. This
2712 allows other classes to implement __radd__ style methods and have them
2713 work as expected.
2714
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002715- Bug #1163325: Decimal infinities failed to hash. Attempting to
2716 hash a NaN raised an InvalidOperation instead of a TypeError.
2717
Tim Petersecc6e6a2005-07-10 22:30:55 +00002718- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002719 stream compression; add, for symmetry reasons, r:* as a synonym of r.

2752
Guido van Rossumd0641422005-02-03 15:01:24 +00002753- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2754 disables recursive traversal through instance attributes, which can
2755 be exploited in various ways.
2756
Tim Peterse3547fd2005-12-16 23:13:57 +00002757- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002758 flags on the HTTP listening socket.
2759
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002760- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2761 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2762
Fred Drakefbdeaad2006-07-29 16:56:15 +00002763- Patches #893642, #1039083: add allow_none, encoding arguments to
2764 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002765

2769
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002770- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2771
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002772- Enhancements to the csv module:
2773
2774 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002775 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002776 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002777 + Dialect parameter parsing has been re-implemented to improve error
2778 reporting.
2779 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2780 dictates.
2781 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002782 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002783 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002784 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2785 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002786 + reader now allows \r characters to be quoted (previously it only allowed
2787 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002788 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002789 + Dialect classes passed to the module are no longer instantiated by
2790 the module before being parsed (the former validation scheme required
2791 this, but the mechanism was unreliable).
2792 + The dialect registry now contains instances of the internal
2793 C-coded dialect type, rather than references to python objects.
2794 + the internal c-coded dialect type is now immutable.
2795 + register_dialect now accepts the same keyword dialect specifications
2796 as the reader and writer, allowing the user to register dialects
2797 without first creating a dialect class.
2798 + a configurable limit to the size of parsed fields has been added -
2799 previously, an unmatched quote character could result in the entire
2800 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002801 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002802 the parser field size limit (returning the former limit). The initial
2803 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002804 + A line_num attribute has been added to the reader object, which tracks
2805 the number of lines read from the source iterator. This is not
2806 the same as the number of records returned, as records can span
2807 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002808 + reader and writer objects were not being registered with the cyclic-GC.
2809 This has been fixed.
2810
Brett Cannone6539c42005-01-08 02:43:53 +00002811- _DummyThread objects in the threading module now delete self.__block that is
2812 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2813 lock primitives tend to be limited in number and thus should not be wasted on
2814 a _DummyThread object. Fixes bug #1089632.
2815
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002816- The imghdr module now detects Exif files.
2817
Raymond Hettinger6065d322004-12-20 23:51:53 +00002818- StringIO.truncate() now correctly adjusts the size attribute.
2819 (Bug #951915).
2820
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002821- locale.py now uses an updated locale alias table (built using
2822 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2823 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002824 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002825
Raymond Hettinger3557f422004-12-07 12:02:02 +00002826- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2827
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002828- the pickle module no longer accepts the deprecated None option in the
2829 args tuple returned by __reduce__().
2830
Brett Cannon84667c02004-12-07 03:25:18 +00002831- optparse now optionally imports gettext. This allows its use in setup.py.
2832
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002833- the pickle module no longer uses the deprecated bin parameter.
2834
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002835- the shelve module no longer uses the deprecated binary parameter.
2836
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002837- the pstats module no longer uses the deprecated ignore() method.
2838
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002839- the filecmp module no longer uses the deprecated use_statcache argument.
2840
Raymond Hettinger664347b2004-12-04 21:21:53 +00002841- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2842 extended or overridden by subclasses. Formerly, the subclassed method would
2843 be ignored by the rest of the module. (Bug #1078905).
2844
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002845- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002846 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002847
Walter Dörwald36733692004-12-22 12:50:50 +00002848- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2849 once when a size argument is given. This prevents a buffer overflow in the
2850 tokenizer with very long source lines.
2851
Barry Warsaw538561e2006-01-01 21:48:54 +00002852- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2853 immediately after creating the object, without any intervening
2854 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002855
Skip Montanaro05885812005-01-16 20:48:27 +00002856- The reconvert.quote function can now emit triple-quoted strings. The
2857 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002858
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002859- ``UserString.MutableString`` now supports negative indices in
2860 ``__setitem__`` and ``__delitem__``
2861
Greg Ward40407942005-03-05 02:53:17 +00002862- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2863 correctly.
2864
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002865- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2866 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2867 character even if the user has passed a size parameter to get a proper
2868 line ending. Remove the special handling of a "\r\n" that has been split
2869 between two lines.
2870
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002871- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2872 about illegal code points. The codec now supports PEP 293 style error
2873 handlers.
2874
Walter Dörwald78a78b02005-09-01 12:04:29 +00002875- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002876 from the input stream, so that the output is a byte string in the correct
2877 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002878
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002879- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2880 considering it exactly like a '*'.
2881
Walter Dörwald007f8df2005-10-09 19:42:27 +00002882- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2883 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002884
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002885- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2886
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002887- Patch #1413711: Certain patterns of differences were making difflib
2888 touch the recursion limit.
2889
Walter Dörwald58917a62006-03-31 15:26:22 +00002890- Bug #947906: An object oriented interface has been added to the calendar
2891 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002892 called as a script (e.g. via ``python -mcalendar``). Localized month and
2893 weekday names can be ouput (even if an exotic encoding is used) using
2894 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002895
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002896Build
2897-----
2898
Neal Norwitz602d3392006-03-31 08:21:40 +00002899- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2900 by using -mieee gcc option.
2901

2903
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002904- Build support for Win64-AMD64 was added.
2905
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002906- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2907
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002908- Patch #881820: look for openpty and forkpty also in libbsd.
2909
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002910- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2911 The zlib module is now builtin on Windows.
2912
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002913- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2914
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002915- Bug #1189330: configure did not correctly determine the necessary
2916 value of LINKCC if python was built with GCC 4.0.
2917
Trent Mick8321b422005-07-26 02:29:21 +00002918- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2919 vulnerability in zlib 1.2.1 and 1.2.2.
2920
Brett Cannon08cd5982005-04-24 22:26:38 +00002921- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2922 flags that change binary compatibility. Changes were also made to
2923 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002924 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002925
Bob Ippolitoed233462005-03-29 13:47:59 +00002926- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2927 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2928 no longer exists). This configure patch makes things right.
2929
Martin v. Löwise2713be2005-03-08 15:03:08 +00002930- Bug #1158607: Build with --disable-unicode again.
2931
Brett Cannon46d96232005-02-16 00:07:19 +00002932- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2933 defined. Discovered as a result of not being able to build on OS X.
2934
Brett Cannon516592f2004-12-07 00:42:59 +00002935- setup.py now uses the directories specified in LDFLAGS using the -L option
2936 and in CPPFLAGS using the -I option for adding library and include
2937 directories, respectively, for compiling extension modules against. This has
2938 led to the core being compiled using the values in CPPFLAGS. It also removes
2939 the need for the special-casing of both DarwinPorts and Fink for darwin since
2940 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2941 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2942 Fink, ``-I/opt/local/include`` for DarwinPorts).
2943
Brett Cannon43802422005-02-10 20:48:03 +00002944- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2945 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2946 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2947 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002949C API
2950-----
2951
Tim Petersc9d78aa2006-03-26 23:27:58 +00002952- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2953 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2954 is obtained via the ``PyObject_`` family, it must be released via the
2955 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2956 always been officially true, but when Python's small-object allocator was
2957 introduced, an attempt was made to cater to a few extension modules
2958 discovered at the time that obtained memory via ``PyObject_New`` but
2959 released it via ``PyMem_DEL``. It's years later, and if such code still
2960 exists it will fail now (probably with segfaults, but calling wrong
2961 low-level memory management functions can yield many symptoms).
2962
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002963- Added a C API for set and frozenset objects.
2964
Raymond Hettinger66517482004-12-03 11:45:13 +00002965- Removed PyRange_New().
2966
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002967- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2968 mapping argument now. This string is used as a mapping table. Byte values
2969 greater than the length of the string and 0xFFFE are treated as undefined
2970 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002976- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002977
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002978- Patch #1276356: New resource "urlfetch" is implemented. This enables
2979 even impatient people to run tests that require remote files.
