briancurtin94eceeb2011-03-14 15:35:35 -0400170- Issue #11491: dbm.error is no longer raised when dbm.open is called with
171 the "n" as the flag argument and the file exists. The behavior matches
172 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +0100173
Mark Dickinson37a79fb2011-03-12 11:12:52 +0000174- Issue #11131: Fix sign of zero in decimal.Decimal plus and minus

R. David Murray43b2f452011-02-11 03:13:19 +0000194- email.header.Header was incorrectly encoding folding white space when
195 rfc2047-encoding header values with embedded newlines, leaving them

197 does for continuation lines that it creates itself.

230 length. Initial patch by Ross Lagerwall.
231
Antoine Pitrou710e9662011-01-19 15:26:37 +0000232- Issue #10898: Allow compiling the posix module when the C library defines
233 a symbol named FSTAT.
234
Antoine Pitroufb7bc3d2011-01-15 16:18:37 +0000235- Issue #10916: mmap should not segfault when a file is mapped using 0 as
236 length and a non-zero offset, and an attempt to read past the end of file
237 is made (IndexError is raised instead). Patch by Ross Lagerwall.

245 node twice.
246
R. David Murray389af002011-01-09 02:48:04 +0000247- Issue #5871: email.header.Header.encode now raises an error if any
248 continuation line in the formatted value has no leading white space
249 and looks like a header. Since Generator uses Header to format all
250 headers, this check is made for all headers in any serialized message
251 at serialization time. This provides protection against header
252 injection attacks.
253
Antoine Pitrouff173852011-01-06 18:29:05 +0000254- Issue #7858: Raise an error properly when os.utime() fails under Windows

Senthil Kumarane5f8e842010-12-29 06:29:58 +0000272 request_uri method. According to RFC 3986, these characters can be a part of

281 it now prints the filename, line number, and traceback to stderr and skips
282 the rest of that individual file, instead of stopping processing entirely.
283
R. David Murray30f9c8c2010-12-21 21:57:54 +0000284- Issue #4871: The zipfile module now gives a more useful error message if

1029 witnessed in test_httpservers.
1030
Antoine Pitrouc2203f92010-04-24 22:07:51 +00001031- Issue #8524: When creating an SSL socket, the timeout value of the
1032 original socket wasn't retained (instead, a socket with a positive timeout
1033 would be turned into a non-blocking SSL socket).
1034
Antoine Pitrouec146182010-04-24 21:30:20 +00001035- Issue #5103: SSL handshake would ignore the socket timeout and block
1036 indefinitely if the other end didn't respond.

2058 and imaginary literals.
2059
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00002060- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

2065 (1) inf and nan strings with trailing whitespace were incorrectly
2066 rejected; (2) parsing of strings representing infinities and nans
2067 was locale aware; and (3) the interpretation of fromhex('-nan')
2068 didn't match that of float('-nan').

2085
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002086- In unittest, using a skipping decorator on a class is now equivalent to
2087 skipping every test on the class. The ClassTestSuite class has been removed.
2088
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002089- Issue #6050: Don't fail extracting a directory from a zipfile if

2117
Antoine Pitroue4501852009-05-14 18:55:55 +00002118- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2119 library. This means, for example, that opening an UTF-16 text file in
2120 append mode doesn't add a BOM at the end of the file if the file isn't
2121 empty.
2122
R. David Murray74b89242009-05-13 17:33:03 +00002123- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

2125 corrects a pydoc regression.
2126
Georg Brandl442d3b32010-08-01 22:33:12 +00002127- Issue #5955: aifc's close method did not close the file it wrapped,

2171Core and Builtins
2172-----------------
2173
Mark Dickinson865e01a2009-05-07 16:37:01 +00002174- Issue #5914: Add new C API function PyOS_string_to_double, and
2175 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2176
Eric Smith741191f2009-05-06 13:08:15 +00002177- Issue #3382: float.__format__, complex.__format__, and %-formatting
2178 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2179 affects nan -> NAN and inf -> INF.
2180
Mark Hammond5a607a32009-05-06 08:04:54 +00002181- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2182 in all operations, including splitdrive, split, etc. splitunc() now issues
2183 a PendingDeprecation warning.
2184
Eric Smith63376222009-05-05 14:04:18 +00002185- Issue #5920: For float.__format__, change the behavior with the
2186 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2187 to be like 'g' but with at least one decimal point and with a
2188 default precision of 12. Previously, the behavior the same but with
2189 a default precision of 6. This more closely matches str(), and
2190 reduces surprises when adding alignment flags to the empty
2191 presentation type. This also affects the new complex.__format__ in
2192 the same way.
2193
Martin v. Löwis011e8422009-05-05 04:43:17 +00002194- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2195
R. David Murrayb18500d2009-05-04 22:59:07 +00002196- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2197 shadowed by classtype's, even if it was None. property now
2198 inserts the __doc__ into the subclass instance __dict__.
2199
Antoine Pitrou244651a2009-05-04 18:56:13 +00002200- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2201 sequences. Patch by Nick Barnes and Victor Stinner.
2202
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002203- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002204
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002205- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2206 received a new method, detach(). detach() disconnects the underlying stream
2207 from the buffer or text IO and returns it.
2208
Mark Dickinson33841c32009-05-01 15:37:04 +00002209- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2210 floats with absolute value over 1e50. Also remove length
2211 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2212 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002213
Eric Smith741191f2009-05-06 13:08:15 +00002214- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002215 format(complex(1, 2./3), '.5') now produces a sensible result.
2216
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002217- Issue #5864: Fix empty format code formatting for floats so that it
2218 never gives more than the requested number of significant digits.
2219
Eric Smith6dc46f52009-04-27 20:39:49 +00002220- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2221 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2222
Eric Smithcc32a112009-04-26 21:35:14 +00002223- Issue #5835: Deprecate PyOS_ascii_formatd.
2224
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002225- Issue #4971: Fix titlecase for characters that are their own
2226 titlecase, but not their own uppercase.
2227
Benjamin Peterson193152c2009-04-25 01:08:45 +00002228- Issue #5283: Setting __class__ in __del__ caused a segfault.
2229
Mark Dickinsonad476da2009-04-23 19:14:16 +00002230- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2231 z involves nans, infs or negative zeros.
2232
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002233- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002234
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002235- Issue #1869 (and many duplicates): make round(x, n) correctly
2236 rounded for a float x, by using the decimal <-> binary conversions
2237 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2238 consistently agrees with format(x, '.2f').
2239
Benjamin Petersonae937c02009-04-18 20:54:08 +00002240- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2241 some builtin types.
2242
Eric Smith0923d1d2009-04-16 20:16:10 +00002243- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2244
Eric Smith35e84722009-04-16 20:21:28 +00002245- Issue #5515: str.format() type 'n' combined with commas and leading
2246 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002247
2248- Implement PEP 378, Format Specifier for Thousands Separator, for
2249 floats.
2250
Mark Dickinson3370cce2009-04-17 22:40:53 +00002251- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002252 1e11, not 1e12. This avoids printing 13 significant digits in
2253 situations where only 12 of them are correct. Example problem
2254 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2255 long time.)
2256
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002257- Issue #1580: On most platforms, use a 'short' float repr: for a
2258 finite float x, repr(x) now outputs a string based on the shortest
2259 sequence of decimal digits that rounds to x. Previous behaviour was
2260 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002261 Another minor difference is that the new repr switches to
2262 exponential notation at 1e16 instead of the previous 1e17; this
2263 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002264
2265 There's a new sys attribute sys.float_repr_style, which takes
2266 the value 'short' to indicate that we're using short float repr,
2267 and 'legacy' if the short float repr isn't available for one
2268 reason or another.
2269
2270 The float repr change involves incorporating David Gay's 'perfect
2271 rounding' code into the Python core (it's in Python/dtoa.c). As a
2272 secondary consequence, all string-to-float and float-to-string
2273 conversions (including all float formatting operations) will be
2274 correctly rounded on these platforms.
2275
Georg Brandl442d3b32010-08-01 22:33:12 +00002276 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002277 this change does not apply.
2278
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002279- Issue #5759: float() didn't call __float__ on str subclasses.
2280
Georg Brandlabc38772009-04-12 15:51:51 +00002281- The string.maketrans() function is deprecated; there is a new static method
2282 maketrans() on the bytes and bytearray classes. This removes confusion about
2283 the types string.maketrans() is supposed to work with, and mirrors the
2284 methods available on the str class.
2285
R. David Murraydc6da8a2009-04-09 22:16:43 +00002286- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2287 its clarity and its speed.
2288
Matthias Klose091c7b12009-04-07 13:24:27 +00002289- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2290 to avoid compiler warnings.
2291
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002292- Issue #3739: The unicode-internal encoder now reports the number of characters
2293 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroub52ec782009-01-25 16:34:23 +00002595- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2596 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2597 evaluation loop is compiled with a new dispatch mechanism which gives
2598 speedups of up to 20%, depending on the system, on various benchmarks.
2599
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002600- Issue #4874: Most builtin decoders now reject unicode input.

2606
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002607- Issue #4838: When a module is deallocated, free the memory backing the
2608 optional module state data.
2609
Mark Dickinson8055afd2009-01-17 10:04:45 +00002610- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2611 type to (void *).
2612
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002613- Issue #4935: The overflow checking code in the expandtabs() method common
2614 to str, bytes and bytearray could be optimized away by the compiler, letting
2615 the interpreter segfault instead of raising an error.
2616
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002617- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2618 __next__ method.
2619
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002620- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2621 function no longer attempt to call the __long__ slot to convert an object
2622 to an integer. Only the __int__ and __trunc__ slots are examined.
2623
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002624- Issue #4893: Use NT threading on CE.

2627
Antoine Pitrouab868312009-01-10 15:40:25 +00002628- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2629 common cases are optimized thanks to a dedicated fast path and a moderate
2630 amount of loop unrolling.
2631
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002632- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2633 collecting the oldest generation) so that allocating lots of objects without
2634 destroying them does not show quadratic performance. Based on a proposal by
2635 Martin von Löwis at
2636 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2637
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002638- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002639 having been closed (for instance, a read() call could return some
2640 previously buffered data). Patch by Dmitry Vasiliev.
2641
Antoine Pitrou05608432009-01-09 18:53:14 +00002642- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2643 flag to work properly. Furthermore, when specifying -u, the text stdout
2644 and stderr streams have line-by-line buffering enabled (the default being
2645 to buffer arbitrary chunks of data).
2646
Raymond Hettinger35631532009-01-09 03:58:09 +00002647- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2648 instead of ints (reducing its size from 4 to 8 times thereby reducing
2649 Python's overall memory).
2650
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002651- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2652 an existing .py counterpart, override the co_filename attributes of all
2653 code objects if the original filename is obsolete (which can happen if the
2654 file has been renamed, moved, or if it is accessed through different paths).
2655 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2656
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002657- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2658 one byte. Also fixes the meaning of len() so that it returns the number of
2659 items, rather than the size in bytes.
2660
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002661- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2662
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002663- Issue #4747: When the terminal does not use utf-8, executing a script with
2664 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2665
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002666- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002667 file with `bytes' filename on Windows.

2670 did not get collected.
2671
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002672- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2673 where the tp_hash and tp_dict slots are both NULL.
2674
Georg Brandlccc47b62008-12-28 11:44:14 +00002675- Issue #4759: None is now allowed as the first argument of
2676 bytearray.translate(). It was always allowed for bytes.translate().
2677
Skip Montanaro80072cb2008-12-23 03:51:14 +00002678- Added test case to ensure attempts to read from a file opened for writing
2679 fail.
2680

2685
Antoine Pitrou621601a2008-12-17 23:18:19 +00002686- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2688 unreachable. Original patch by Neil Schemenauer.
2689

2691
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002692- Issue #2173: When getting device encoding, check that return value of
2693 nl_langinfo is not the empty string. This was causing silent build
2694 failures on OS X.
2695
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002696- Issue #4597: Fixed several opcodes that weren't always propagating
2697 exceptions.
2698
2699- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002700 context manager returns a value that cannot be converted to a bool.
2701
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002702- Issue #4445: Replace "sizeof(PyBytesObject)" with
2703 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2704 bytes instances. On a typical machine this saves 3 bytes of memory
2705 (on average) per allocation of a bytes instance.
2706
Christian Heimesa872de52008-12-05 08:26:55 +00002707- Issue #4533: File read operation was dreadfully slow due to a slowly
2708 growing read buffer. Fixed by using the same growth rate algorithm as
2709 Python 2.x.
2710
Antoine Pitrou5504e892008-12-06 21:27:53 +00002711- Issue #4509: Various issues surrounding resize of bytearray objects to
2712 which there are buffer exports (e.g. memoryview instances).
2713
Georg Brandlf9734072008-12-07 15:30:06 +00002714- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2715 method on file objects with closefd=False. The file descriptor is still
2716 kept open but the file object behaves like a closed file. The ``FileIO``
2717 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002718
Antoine Pitroubc420402008-12-07 20:14:49 +00002719- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2725
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002726- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2727 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2728 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2729 of using the replace error handler in PyUnicode_DecodeUTF8().

3008 do an explicit seek to the end of file (so that e.g. tell() returns the
