briancurtin94eceeb2011-03-14 15:35:35 -0400205- Issue #11491: dbm.error is no longer raised when dbm.open is called with
206 the "n" as the flag argument and the file exists. The behavior matches
207 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +0100208

R. David Murray43b2f452011-02-11 03:13:19 +0000229- email.header.Header was incorrectly encoding folding white space when
230 rfc2047-encoding header values with embedded newlines, leaving them
231 without folding whitespace. It now uses the continuation_ws, as it
232 does for continuation lines that it creates itself.

283 continuation line in the formatted value has no leading white space
284 and looks like a header. Since Generator uses Header to format all
285 headers, this check is made for all headers in any serialized message

287 injection attacks.

1035 Decimal operation raises multiple signals and more than one of those

1038 being followed, leading to the wrong Python exception being raised.

1067 where the method could block indefinitely if called just before the
1068 event loop started running. This also fixes the occasional freezes
1069 witnessed in test_httpservers.
1070
Antoine Pitrouc2203f92010-04-24 22:07:51 +00001071- Issue #8524: When creating an SSL socket, the timeout value of the
1072 original socket wasn't retained (instead, a socket with a positive timeout
1073 would be turned into a non-blocking SSL socket).
1074
Antoine Pitrouec146182010-04-24 21:30:20 +00001075- Issue #5103: SSL handshake would ignore the socket timeout and block
1076 indefinitely if the other end didn't respond.
1077
1078- The do_handshake() method of SSL objects now adjusts the blocking mode of
1079 the SSL structure if necessary (as other methods already do).

1082 a non-infinite timeout. Also make that method friendlier with applications
1083 wanting to continue using the socket in clear-text mode, by disabling
1084 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1127 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1128 reads and writes are always retried by OpenSSL itself.

2105 (1) inf and nan strings with trailing whitespace were incorrectly
2106 rejected; (2) parsing of strings representing infinities and nans
2107 was locale aware; and (3) the interpretation of fromhex('-nan')

2125
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002126- In unittest, using a skipping decorator on a class is now equivalent to

2128
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002129- Issue #6050: Don't fail extracting a directory from a zipfile if

2135
Antoine Pitrou716c4442009-05-23 19:04:03 +00002136- Issue #5761: Add the name of the underlying file to the repr() of various

2157
Antoine Pitroue4501852009-05-14 18:55:55 +00002158- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2159 library. This means, for example, that opening an UTF-16 text file in
2160 append mode doesn't add a BOM at the end of the file if the file isn't
2161 empty.

2211Core and Builtins
2212-----------------
2213
Mark Dickinson865e01a2009-05-07 16:37:01 +00002214- Issue #5914: Add new C API function PyOS_string_to_double, and
2215 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2216
Eric Smith741191f2009-05-06 13:08:15 +00002217- Issue #3382: float.__format__, complex.__format__, and %-formatting
2218 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2219 affects nan -> NAN and inf -> INF.
2220
Mark Hammond5a607a32009-05-06 08:04:54 +00002221- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2222 in all operations, including splitdrive, split, etc. splitunc() now issues
2223 a PendingDeprecation warning.
2224
Eric Smith63376222009-05-05 14:04:18 +00002225- Issue #5920: For float.__format__, change the behavior with the
2226 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2227 to be like 'g' but with at least one decimal point and with a
2228 default precision of 12. Previously, the behavior the same but with
2229 a default precision of 6. This more closely matches str(), and
2230 reduces surprises when adding alignment flags to the empty
2231 presentation type. This also affects the new complex.__format__ in
2232 the same way.
2233
Martin v. Löwis011e8422009-05-05 04:43:17 +00002234- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2235
R. David Murrayb18500d2009-05-04 22:59:07 +00002236- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2237 shadowed by classtype's, even if it was None. property now
2238 inserts the __doc__ into the subclass instance __dict__.
2239
Antoine Pitrou244651a2009-05-04 18:56:13 +00002240- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2241 sequences. Patch by Nick Barnes and Victor Stinner.
2242
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002243- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002244
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002245- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2246 received a new method, detach(). detach() disconnects the underlying stream
2247 from the buffer or text IO and returns it.
2248
Mark Dickinson33841c32009-05-01 15:37:04 +00002249- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2250 floats with absolute value over 1e50. Also remove length
2251 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2252 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002253
Eric Smith741191f2009-05-06 13:08:15 +00002254- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002255 format(complex(1, 2./3), '.5') now produces a sensible result.
2256
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002257- Issue #5864: Fix empty format code formatting for floats so that it
2258 never gives more than the requested number of significant digits.
2259
Eric Smith6dc46f52009-04-27 20:39:49 +00002260- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2261 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2262
Eric Smithcc32a112009-04-26 21:35:14 +00002263- Issue #5835: Deprecate PyOS_ascii_formatd.
2264
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002265- Issue #4971: Fix titlecase for characters that are their own
2266 titlecase, but not their own uppercase.
2267
Benjamin Peterson193152c2009-04-25 01:08:45 +00002268- Issue #5283: Setting __class__ in __del__ caused a segfault.
2269
Mark Dickinsonad476da2009-04-23 19:14:16 +00002270- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2271 z involves nans, infs or negative zeros.
2272
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002273- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002274
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002275- Issue #1869 (and many duplicates): make round(x, n) correctly
2276 rounded for a float x, by using the decimal <-> binary conversions
2277 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2278 consistently agrees with format(x, '.2f').
2279
Benjamin Petersonae937c02009-04-18 20:54:08 +00002280- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2281 some builtin types.
2282
Eric Smith0923d1d2009-04-16 20:16:10 +00002283- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2284
Eric Smith35e84722009-04-16 20:21:28 +00002285- Issue #5515: str.format() type 'n' combined with commas and leading
2286 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002287
2288- Implement PEP 378, Format Specifier for Thousands Separator, for
2289 floats.
2290
Mark Dickinson3370cce2009-04-17 22:40:53 +00002291- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002292 1e11, not 1e12. This avoids printing 13 significant digits in
2293 situations where only 12 of them are correct. Example problem
2294 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2295 long time.)
2296
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002297- Issue #1580: On most platforms, use a 'short' float repr: for a
2298 finite float x, repr(x) now outputs a string based on the shortest
2299 sequence of decimal digits that rounds to x. Previous behaviour was
2300 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002301 Another minor difference is that the new repr switches to
2302 exponential notation at 1e16 instead of the previous 1e17; this
2303 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002304
2305 There's a new sys attribute sys.float_repr_style, which takes
2306 the value 'short' to indicate that we're using short float repr,
2307 and 'legacy' if the short float repr isn't available for one
2308 reason or another.
2309
2310 The float repr change involves incorporating David Gay's 'perfect
2311 rounding' code into the Python core (it's in Python/dtoa.c). As a
2312 secondary consequence, all string-to-float and float-to-string
2313 conversions (including all float formatting operations) will be
2314 correctly rounded on these platforms.
2315
Georg Brandl442d3b32010-08-01 22:33:12 +00002316 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002317 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002319- Issue #5759: float() didn't call __float__ on str subclasses.
2320
Georg Brandlabc38772009-04-12 15:51:51 +00002321- The string.maketrans() function is deprecated; there is a new static method
2322 maketrans() on the bytes and bytearray classes. This removes confusion about
2323 the types string.maketrans() is supposed to work with, and mirrors the
2324 methods available on the str class.

2598-----------------
2599
Benjamin Peterson4fa88fa2009-03-04 00:14:51 +00002600- The io module has been reimplemented in C for speed.
2601
Raymond Hettingerb0d56af2009-03-03 10:52:49 +00002602- Give dict views an informative __repr__.
2603
Eric Smith5e5c0db2009-02-20 14:25:03 +00002604- Issue #5247: Improve error message when unknown format codes are
2605 used when using str.format() with str, int, and float arguments.
2606
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00002607- Issue #5249: time.strftime returned malformed string when format string
2608 contained non ascii character on windows.
2609
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002610- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2611 source has already been decoded into str.
2612
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002613- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2614 rotating the object pointer by 4 bits to the right.
2615
Mark Dickinson87ec0852009-02-09 17:15:59 +00002616- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2617 it now forces its argument to double before testing for infinity.
2618
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002619- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2620 returns a non-number type.
2621
Benjamin Peterson87618552009-02-08 15:00:52 +00002622- Issue #5182: Removed memoryview.__str__.

Mark Dickinsone94c6792009-02-02 20:36:42 +00002626 the type definition cmpfunc. The tp_compare slot has been renamed
2627 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002628
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002629- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002630 were suppressing all exceptions. These include list() and bytearray().
2631
Mark Dickinson1124e712009-01-28 21:25:58 +00002632- Issue #4707: round(x, n) now returns an integer if x is an integer.
2633 Previously it returned a float.
2634
Antoine Pitroub52ec782009-01-25 16:34:23 +00002635- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2636 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2637 evaluation loop is compiled with a new dispatch mechanism which gives
2638 speedups of up to 20%, depending on the system, on various benchmarks.
2639
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002640- Issue #4874: Most builtin decoders now reject unicode input.

2643 from a string.
2644
Benjamin Peterson05e782f2009-01-19 15:15:02 +00002645- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
2646
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002647- Issue #4838: When a module is deallocated, free the memory backing the
2648 optional module state data.
2649
Mark Dickinson8055afd2009-01-17 10:04:45 +00002650- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2651 type to (void *).
2652
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002653- Issue #4935: The overflow checking code in the expandtabs() method common
2654 to str, bytes and bytearray could be optimized away by the compiler, letting
2655 the interpreter segfault instead of raising an error.
2656
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002657- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2658 __next__ method.
2659
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002660- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2661 function no longer attempt to call the __long__ slot to convert an object
2662 to an integer. Only the __int__ and __trunc__ slots are examined.
2663
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002664- Issue #4893: Use NT threading on CE.
2665
Martin v. Löwisec59d042009-01-12 07:59:10 +00002666- Issue #4915: Port sysmodule to Windows CE.
2667
Antoine Pitrouab868312009-01-10 15:40:25 +00002668- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2669 common cases are optimized thanks to a dedicated fast path and a moderate
2670 amount of loop unrolling.
2671
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002672- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2673 collecting the oldest generation) so that allocating lots of objects without
2674 destroying them does not show quadratic performance. Based on a proposal by
2675 Martin von Löwis at
2676 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2677
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002678- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002679 having been closed (for instance, a read() call could return some
2680 previously buffered data). Patch by Dmitry Vasiliev.
2681
Antoine Pitrou05608432009-01-09 18:53:14 +00002682- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2683 flag to work properly. Furthermore, when specifying -u, the text stdout
2684 and stderr streams have line-by-line buffering enabled (the default being
2685 to buffer arbitrary chunks of data).
2686
Raymond Hettinger35631532009-01-09 03:58:09 +00002687- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2688 instead of ints (reducing its size from 4 to 8 times thereby reducing
2689 Python's overall memory).
2690
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002691- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2692 an existing .py counterpart, override the co_filename attributes of all
2693 code objects if the original filename is obsolete (which can happen if the
2694 file has been renamed, moved, or if it is accessed through different paths).
2695 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2696
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002697- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2698 one byte. Also fixes the meaning of len() so that it returns the number of
2699 items, rather than the size in bytes.
2700
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002701- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2702
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002703- Issue #4747: When the terminal does not use utf-8, executing a script with
2704 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2705
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002706- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002707 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002708
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002709- Issue #3680: Reference cycles created through a dict, set or deque iterator
2710 did not get collected.
2711
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002712- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2713 where the tp_hash and tp_dict slots are both NULL.
2714
Georg Brandlccc47b62008-12-28 11:44:14 +00002715- Issue #4759: None is now allowed as the first argument of
2716 bytearray.translate(). It was always allowed for bytes.translate().
2717
Skip Montanaro80072cb2008-12-23 03:51:14 +00002718- Added test case to ensure attempts to read from a file opened for writing
2719 fail.
2720
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002721- Issue #3106: Speedup some comparisons (str/str and int/int).
2722
Antoine Pitrouf289ae62008-12-18 11:06:25 +00002723- Issue #2183: Simplify and optimize bytecode for list, dict and set
2724 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2725
Antoine Pitrou621601a2008-12-17 23:18:19 +00002726- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2727 print elapsed times, not only when some objects are uncollectable /
2728 unreachable. Original patch by Neil Schemenauer.
2729
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002730- Issue #3439: Add a bit_length method to int.
2731
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002732- Issue #2173: When getting device encoding, check that return value of
2733 nl_langinfo is not the empty string. This was causing silent build
2734 failures on OS X.
2735
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002736- Issue #4597: Fixed several opcodes that weren't always propagating
2737 exceptions.
2738
2739- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002740 context manager returns a value that cannot be converted to a bool.
2741
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002742- Issue #4445: Replace "sizeof(PyBytesObject)" with
2743 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2744 bytes instances. On a typical machine this saves 3 bytes of memory
2745 (on average) per allocation of a bytes instance.
2746
Christian Heimesa872de52008-12-05 08:26:55 +00002747- Issue #4533: File read operation was dreadfully slow due to a slowly
2748 growing read buffer. Fixed by using the same growth rate algorithm as
2749 Python 2.x.
2750
Antoine Pitrou5504e892008-12-06 21:27:53 +00002751- Issue #4509: Various issues surrounding resize of bytearray objects to
2752 which there are buffer exports (e.g. memoryview instances).
2753
Georg Brandlf9734072008-12-07 15:30:06 +00002754- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2755 method on file objects with closefd=False. The file descriptor is still
2756 kept open but the file object behaves like a closed file. The ``FileIO``
2757 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002758
Antoine Pitroubc420402008-12-07 20:14:49 +00002759- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2760 larger than 1.
2761
Benjamin Peterson371ccfb2008-12-27 19:03:36 +00002762- Issue #4748: Lambda generators no longer return a value.
2763
Gregory P. Smithccc5ae72009-03-02 05:21:55 +00002764- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2765
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002766- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2767 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2768 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2769 of using the replace error handler in PyUnicode_DecodeUTF8().
