briancurtin94eceeb2011-03-14 15:35:35 -0400154- Issue #11491: dbm.error is no longer raised when dbm.open is called with
155 the "n" as the flag argument and the file exists. The behavior matches
156 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +0100157
Mark Dickinson37a79fb2011-03-12 11:12:52 +0000158- Issue #11131: Fix sign of zero in decimal.Decimal plus and minus

176 32-bit Windows.
177
R. David Murray43b2f452011-02-11 03:13:19 +0000178- email.header.Header was incorrectly encoding folding white space when
179 rfc2047-encoding header values with embedded newlines, leaving them
180 without folding whitespace. It now uses the continuation_ws, as it
181 does for continuation lines that it creates itself.

214 length. Initial patch by Ross Lagerwall.
215
Antoine Pitrou710e9662011-01-19 15:26:37 +0000216- Issue #10898: Allow compiling the posix module when the C library defines
217 a symbol named FSTAT.
218
Antoine Pitroufb7bc3d2011-01-15 16:18:37 +0000219- Issue #10916: mmap should not segfault when a file is mapped using 0 as
220 length and a non-zero offset, and an attempt to read past the end of file
221 is made (IndexError is raised instead). Patch by Ross Lagerwall.

230
R. David Murray389af002011-01-09 02:48:04 +0000231- Issue #5871: email.header.Header.encode now raises an error if any
232 continuation line in the formatted value has no leading white space
233 and looks like a header. Since Generator uses Header to format all
234 headers, this check is made for all headers in any serialized message
235 at serialization time. This provides protection against header
236 injection attacks.
237
Antoine Pitrouff173852011-01-06 18:29:05 +0000238- Issue #7858: Raise an error properly when os.utime() fails under Windows

Senthil Kumarane5f8e842010-12-29 06:29:58 +0000256 request_uri method. According to RFC 3986, these characters can be a part of

263
R. David Murray6cb252f2010-12-26 22:24:54 +0000264- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
265 it now prints the filename, line number, and traceback to stderr and skips
266 the rest of that individual file, instead of stopping processing entirely.
267
R. David Murray30f9c8c2010-12-21 21:57:54 +0000268- Issue #4871: The zipfile module now gives a more useful error message if

2027 that would raise SystemError.
2028
Raymond Hettinger2bcde142009-05-29 04:52:27 +00002029- Issue #5982: staticmethod and classmethod now expose the wrapped
2030 function with __func__.
2031
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00002032- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00002035- Issue #5829: complex("1e500") no longer raises OverflowError. This
2036 makes it consistent with float("1e500") and interpretation of real
2037 and imaginary literals.
2038
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00002039- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00002043- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
2044 (1) inf and nan strings with trailing whitespace were incorrectly
2045 rejected; (2) parsing of strings representing infinities and nans
2046 was locale aware; and (3) the interpretation of fromhex('-nan')
2047 didn't match that of float('-nan').

2064
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002065- In unittest, using a skipping decorator on a class is now equivalent to
2066 skipping every test on the class. The ClassTestSuite class has been removed.
2067
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002068- Issue #6050: Don't fail extracting a directory from a zipfile if

2070
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002071- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2072 than an int, which makes some operations possible under 64-bit Linux (e.g.
2073 DN_MULTISHOT with F_NOTIFY).
2074
Antoine Pitrou716c4442009-05-23 19:04:03 +00002075- Issue #5761: Add the name of the underlying file to the repr() of various

2082 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2083 a process identifier type wider than the standard C integer type.
2084

2096
Antoine Pitroue4501852009-05-14 18:55:55 +00002097- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2098 library. This means, for example, that opening an UTF-16 text file in
2099 append mode doesn't add a BOM at the end of the file if the file isn't
2100 empty.
2101
R. David Murray74b89242009-05-13 17:33:03 +00002102- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

2104 corrects a pydoc regression.
2105
Georg Brandl442d3b32010-08-01 22:33:12 +00002106- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00002107 now it does. This also means getfp method now returns the real fp.

2150Core and Builtins
2151-----------------
2152
Mark Dickinson865e01a2009-05-07 16:37:01 +00002153- Issue #5914: Add new C API function PyOS_string_to_double, and
2154 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2155
Eric Smith741191f2009-05-06 13:08:15 +00002156- Issue #3382: float.__format__, complex.__format__, and %-formatting
2157 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2158 affects nan -> NAN and inf -> INF.
2159
Mark Hammond5a607a32009-05-06 08:04:54 +00002160- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2161 in all operations, including splitdrive, split, etc. splitunc() now issues
2162 a PendingDeprecation warning.
2163
Eric Smith63376222009-05-05 14:04:18 +00002164- Issue #5920: For float.__format__, change the behavior with the
2165 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2166 to be like 'g' but with at least one decimal point and with a
2167 default precision of 12. Previously, the behavior the same but with
2168 a default precision of 6. This more closely matches str(), and
2169 reduces surprises when adding alignment flags to the empty
2170 presentation type. This also affects the new complex.__format__ in
2171 the same way.
2172
Martin v. Löwis011e8422009-05-05 04:43:17 +00002173- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2174
R. David Murrayb18500d2009-05-04 22:59:07 +00002175- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2176 shadowed by classtype's, even if it was None. property now
2177 inserts the __doc__ into the subclass instance __dict__.
2178
Antoine Pitrou244651a2009-05-04 18:56:13 +00002179- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2180 sequences. Patch by Nick Barnes and Victor Stinner.
2181
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002182- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002183
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002184- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2185 received a new method, detach(). detach() disconnects the underlying stream
2186 from the buffer or text IO and returns it.
2187
Mark Dickinson33841c32009-05-01 15:37:04 +00002188- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2189 floats with absolute value over 1e50. Also remove length
2190 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2191 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002192
Eric Smith741191f2009-05-06 13:08:15 +00002193- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002194 format(complex(1, 2./3), '.5') now produces a sensible result.
2195
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002196- Issue #5864: Fix empty format code formatting for floats so that it
2197 never gives more than the requested number of significant digits.
2198
Eric Smith6dc46f52009-04-27 20:39:49 +00002199- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2200 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2201
Eric Smithcc32a112009-04-26 21:35:14 +00002202- Issue #5835: Deprecate PyOS_ascii_formatd.
2203
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002204- Issue #4971: Fix titlecase for characters that are their own
2205 titlecase, but not their own uppercase.
2206
Benjamin Peterson193152c2009-04-25 01:08:45 +00002207- Issue #5283: Setting __class__ in __del__ caused a segfault.
2208
Mark Dickinsonad476da2009-04-23 19:14:16 +00002209- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2210 z involves nans, infs or negative zeros.
2211
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002212- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002213
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002214- Issue #1869 (and many duplicates): make round(x, n) correctly
2215 rounded for a float x, by using the decimal <-> binary conversions
2216 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2217 consistently agrees with format(x, '.2f').
2218
Benjamin Petersonae937c02009-04-18 20:54:08 +00002219- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2220 some builtin types.
2221
Eric Smith0923d1d2009-04-16 20:16:10 +00002222- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2223
Eric Smith35e84722009-04-16 20:21:28 +00002224- Issue #5515: str.format() type 'n' combined with commas and leading
2225 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002226
2227- Implement PEP 378, Format Specifier for Thousands Separator, for
2228 floats.
2229
Mark Dickinson3370cce2009-04-17 22:40:53 +00002230- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002231 1e11, not 1e12. This avoids printing 13 significant digits in
2232 situations where only 12 of them are correct. Example problem
2233 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2234 long time.)
2235
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002236- Issue #1580: On most platforms, use a 'short' float repr: for a
2237 finite float x, repr(x) now outputs a string based on the shortest
2238 sequence of decimal digits that rounds to x. Previous behaviour was
2239 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002240 Another minor difference is that the new repr switches to
2241 exponential notation at 1e16 instead of the previous 1e17; this
2242 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002243
2244 There's a new sys attribute sys.float_repr_style, which takes
2245 the value 'short' to indicate that we're using short float repr,
2246 and 'legacy' if the short float repr isn't available for one
2247 reason or another.
2248
2249 The float repr change involves incorporating David Gay's 'perfect
2250 rounding' code into the Python core (it's in Python/dtoa.c). As a
2251 secondary consequence, all string-to-float and float-to-string
2252 conversions (including all float formatting operations) will be
2253 correctly rounded on these platforms.
2254
Georg Brandl442d3b32010-08-01 22:33:12 +00002255 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002256 this change does not apply.
2257
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002258- Issue #5759: float() didn't call __float__ on str subclasses.
2259
Georg Brandlabc38772009-04-12 15:51:51 +00002260- The string.maketrans() function is deprecated; there is a new static method
2261 maketrans() on the bytes and bytearray classes. This removes confusion about
2262 the types string.maketrans() is supposed to work with, and mirrors the
2263 methods available on the str class.
2264
R. David Murraydc6da8a2009-04-09 22:16:43 +00002265- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2266 its clarity and its speed.
2267
Matthias Klose091c7b12009-04-07 13:24:27 +00002268- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2269 to avoid compiler warnings.
2270
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002271- Issue #3739: The unicode-internal encoder now reports the number of characters
2272 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwisec59d042009-01-12 07:59:10 +00002605- Issue #4915: Port sysmodule to Windows CE.
2606
Antoine Pitrouab868312009-01-10 15:40:25 +00002607- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2608 common cases are optimized thanks to a dedicated fast path and a moderate
2609 amount of loop unrolling.
2610
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002611- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2612 collecting the oldest generation) so that allocating lots of objects without
2613 destroying them does not show quadratic performance. Based on a proposal by
2614 Martin von Löwis at
2615 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2616
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002617- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002618 having been closed (for instance, a read() call could return some
2619 previously buffered data). Patch by Dmitry Vasiliev.
2620
Antoine Pitrou05608432009-01-09 18:53:14 +00002621- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2622 flag to work properly. Furthermore, when specifying -u, the text stdout
2623 and stderr streams have line-by-line buffering enabled (the default being
2624 to buffer arbitrary chunks of data).
2625
Raymond Hettinger35631532009-01-09 03:58:09 +00002626- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2627 instead of ints (reducing its size from 4 to 8 times thereby reducing
2628 Python's overall memory).
2629
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002630- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2631 an existing .py counterpart, override the co_filename attributes of all
2632 code objects if the original filename is obsolete (which can happen if the
2633 file has been renamed, moved, or if it is accessed through different paths).
2634 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2635
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002636- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2637 one byte. Also fixes the meaning of len() so that it returns the number of
2638 items, rather than the size in bytes.
2639
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002640- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2641
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002642- Issue #4747: When the terminal does not use utf-8, executing a script with
2643 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2644
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002645- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002646 file with `bytes' filename on Windows.

2649 did not get collected.
2650
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002651- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2652 where the tp_hash and tp_dict slots are both NULL.
2653
Georg Brandlccc47b62008-12-28 11:44:14 +00002654- Issue #4759: None is now allowed as the first argument of
2655 bytearray.translate(). It was always allowed for bytes.translate().
2656
Skip Montanaro80072cb2008-12-23 03:51:14 +00002657- Added test case to ensure attempts to read from a file opened for writing
2658 fail.
2659

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002662- Issue #2183: Simplify and optimize bytecode for list, dict and set
2663 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2664
Antoine Pitrou621601a2008-12-17 23:18:19 +00002665- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2666 print elapsed times, not only when some objects are uncollectable /
2667 unreachable. Original patch by Neil Schemenauer.
2668
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002669- Issue #3439: Add a bit_length method to int.
2670
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002671- Issue #2173: When getting device encoding, check that return value of
2672 nl_langinfo is not the empty string. This was causing silent build
2673 failures on OS X.
2674
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002675- Issue #4597: Fixed several opcodes that weren't always propagating
2676 exceptions.
2677
2678- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002679 context manager returns a value that cannot be converted to a bool.
2680
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002681- Issue #4445: Replace "sizeof(PyBytesObject)" with
2682 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2683 bytes instances. On a typical machine this saves 3 bytes of memory
2684 (on average) per allocation of a bytes instance.
2685
Christian Heimesa872de52008-12-05 08:26:55 +00002686- Issue #4533: File read operation was dreadfully slow due to a slowly
2687 growing read buffer. Fixed by using the same growth rate algorithm as
2688 Python 2.x.
2689
Antoine Pitrou5504e892008-12-06 21:27:53 +00002690- Issue #4509: Various issues surrounding resize of bytearray objects to
2691 which there are buffer exports (e.g. memoryview instances).
2692
Georg Brandlf9734072008-12-07 15:30:06 +00002693- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2694 method on file objects with closefd=False. The file descriptor is still
2695 kept open but the file object behaves like a closed file. The ``FileIO``
2696 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002697
Antoine Pitroubc420402008-12-07 20:14:49 +00002698- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2699 larger than 1.

2704
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002705- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2706 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2707 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2708 of using the replace error handler in PyUnicode_DecodeUTF8().

2985
Antoine Pitrou08838b62009-01-21 00:55:13 +00002986- Issue #5008: When a file is opened in append mode with the new IO library,
2987 do an explicit seek to the end of file (so that e.g. tell() returns the
2988 file size rather than 0). This is consistent with the behaviour of the
