142Core and Builtins
143-----------------
144

151
Ezio Melotti57221d02010-07-01 07:32:02 +0000152- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000153 start byte and the continuation byte(s) are now considered invalid, instead of
154 the number of bytes specified by the start byte. E.g.:
155 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
156 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
157 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
158 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +0000159
Georg Brandl62069d32010-07-31 08:56:11 +0000160- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
161 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +0000162
Benjamin Peterson88968ad2010-06-25 19:30:21 +0000163- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +0000172- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
173 dealing with unary minus applied to a constant. The removed code was mutating
174 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +0000175
Victor Stinner554f3f02010-06-16 23:33:54 +0000176- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000177 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000178 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000179 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000180
Victor Stinner25e8ec42010-06-25 00:02:38 +0000181- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
182 "w*" format instead. Add tests for "w*" format.
183
Victor Stinner06e49dd2010-06-13 18:21:50 +0000184- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000185 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +0000186 string formats.
187
Georg Brandl62069d32010-07-31 08:56:11 +0000188- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000189 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
190 location of the raised exception.
191
Victor Stinner313a1202010-06-11 23:56:51 +0000192- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
193 filenames and enable os.fsencode().
194
Benjamin Peterson285a6892010-06-22 19:21:52 +0000195- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
196

198 interpreter with characters outside the Basic Multilingual Plane (higher than
199 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000200
Georg Brandl62069d32010-07-31 08:56:11 +0000201- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
202 TypeError instead of giving a DeprecationWarning when a float is parsed using
203 the 'L' code (for long long). (All other integer codes already raise
204 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000205
Victor Stinner600d3be2010-06-10 12:00:55 +0000206- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
207 enable shortcuts for upper case encoding name. Add also a shortcut for
208 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
209
Georg Brandl62069d32010-07-31 08:56:11 +0000210- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
211 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000212
213- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000214 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000215 like bytearray.
216
Georg Brandl62069d32010-07-31 08:56:11 +0000217- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000218 used anymore and it was never documented.
219
Georg Brandl62069d32010-07-31 08:56:11 +0000220- In str.format(), raise a ValueError when indexes to arguments are too large.

223 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000224
Georg Brandl62069d32010-07-31 08:56:11 +0000225- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
226 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
227 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
228 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000229
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000230- Issue #8748: Fix two issues with comparisons between complex and integer
231 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000232 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
233 (2) The comparison raised an OverflowError for large integers, leading to
234 unpredictable exceptions when combining integers and complex objects in sets
235 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000236
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000237- Issue #8766: Initialize _warnings module before importing the first module.

239
Victor Stinner9ca9c252010-05-19 16:53:30 +0000240- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
241 encoding and surrogateespace error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000242 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000243
Georg Brandl62069d32010-07-31 08:56:11 +0000244- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
245 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000246
Victor Stinnerae6265f2010-05-15 16:27:27 +0000247- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
248 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000249 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000250 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000251
Victor Stinner59e62db2010-05-15 13:14:32 +0000252- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000253 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000254
Victor Stinnerb744ba12010-05-15 12:27:16 +0000255- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000256 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000257 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
258
Victor Stinner0964ee12010-04-30 16:48:45 +0000259- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000260 PyUnicode_FromString() to support surrogates in the filename and use the right
261 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000262
Georg Brandl8569e582010-05-19 20:57:08 +0000263- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000266
Benjamin Petersonfb886362010-04-24 18:21:17 +0000267- Issue #8419: Prevent the dict constructor from accepting non-string keyword
268 arguments.
269
Victor Stinner14284c22010-04-23 12:02:30 +0000270- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute

670 applications that use a lot of regular expressions and limits the impact of
671 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00001085- Issue #2531: Comparison operations between floats and Decimal instances now
1086 return a result based on the numeric values of the operands; previously they
1087 returned an arbitrary result based on the relative ordering of id(float) and
1088 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1089 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00001090
Raymond Hettinger9c01e442010-04-03 10:32:58 +00001091- Added a subtract() method to collections.Counter().
1092
Barry Warsawd5f9bf52010-03-31 21:36:22 +00001093- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001094 argument `-` which tells it to read files to compile from stdin. Each line is
1095 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna806d8cf2010-03-30 19:34:18 +00001098- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

1103 Fractions instance now raise TypeError instead of returning True/False. This
1104 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1105 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001152- subprocess.Popen now has restore_signals and start_new_session features. The
1153 default of restore_signals=True is a new behavior compared to earlier Python
1154 versions. This means that signals such as SIGPIPE are not ignored by default
1155 in subprocesses launched by Python (Issue #1652).

1249 a :class:`io.BufferedReader` object for more speedups. It also solves an
1250 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001642- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00001643 compared to other unix systems. In particular, os.getgroups() does not reflect
1644 any changes made using os.setgroups() but basicly always returns the same
1645 information as the id command. os.getgroups() can now return more than 16
1646 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00002010 runtest_inner in regrtest, with warnings if the called test modifies them, and

2202
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002203- In unittest, using a skipping decorator on a class is now equivalent to
2204 skipping every test on the class. The ClassTestSuite class has been removed.
2205
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002206- Issue #6050: Don't fail extracting a directory from a zipfile if
2207 the directory already exists.
2208
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002209- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2210 than an int, which makes some operations possible under 64-bit Linux (e.g.
2211 DN_MULTISHOT with F_NOTIFY).
2212
Antoine Pitrou716c4442009-05-23 19:04:03 +00002213- Issue #5761: Add the name of the underlying file to the repr() of various

2220 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2221 a process identifier type wider than the standard C integer type.
2222

2234
Antoine Pitroue4501852009-05-14 18:55:55 +00002235- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2236 library. This means, for example, that opening an UTF-16 text file in
2237 append mode doesn't add a BOM at the end of the file if the file isn't
2238 empty.
2239
R. David Murray74b89242009-05-13 17:33:03 +00002240- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

2242 corrects a pydoc regression.
2243
Georg Brandl5f90d792010-08-01 22:31:05 +00002244- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00002245 now it does. This also means getfp method now returns the real fp.

2288Core and Builtins
2289-----------------
2290
Mark Dickinson865e01a2009-05-07 16:37:01 +00002291- Issue #5914: Add new C API function PyOS_string_to_double, and
2292 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2293
Eric Smith741191f2009-05-06 13:08:15 +00002294- Issue #3382: float.__format__, complex.__format__, and %-formatting
2295 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2296 affects nan -> NAN and inf -> INF.
2297
Mark Hammond5a607a32009-05-06 08:04:54 +00002298- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2299 in all operations, including splitdrive, split, etc. splitunc() now issues
2300 a PendingDeprecation warning.
2301
Eric Smith63376222009-05-05 14:04:18 +00002302- Issue #5920: For float.__format__, change the behavior with the
2303 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2304 to be like 'g' but with at least one decimal point and with a
2305 default precision of 12. Previously, the behavior the same but with
2306 a default precision of 6. This more closely matches str(), and
2307 reduces surprises when adding alignment flags to the empty
2308 presentation type. This also affects the new complex.__format__ in
2309 the same way.
2310
Martin v. Löwis011e8422009-05-05 04:43:17 +00002311- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2312
R. David Murrayb18500d2009-05-04 22:59:07 +00002313- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2314 shadowed by classtype's, even if it was None. property now
2315 inserts the __doc__ into the subclass instance __dict__.
2316
Antoine Pitrou244651a2009-05-04 18:56:13 +00002317- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2318 sequences. Patch by Nick Barnes and Victor Stinner.
2319
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002320- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002321
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002322- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2323 received a new method, detach(). detach() disconnects the underlying stream
2324 from the buffer or text IO and returns it.
2325
Mark Dickinson33841c32009-05-01 15:37:04 +00002326- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2327 floats with absolute value over 1e50. Also remove length
2328 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2329 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002330
Eric Smith741191f2009-05-06 13:08:15 +00002331- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002332 format(complex(1, 2./3), '.5') now produces a sensible result.
2333
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002334- Issue #5864: Fix empty format code formatting for floats so that it
2335 never gives more than the requested number of significant digits.
2336
Eric Smith6dc46f52009-04-27 20:39:49 +00002337- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2338 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2339
Eric Smithcc32a112009-04-26 21:35:14 +00002340- Issue #5835: Deprecate PyOS_ascii_formatd.
2341
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002342- Issue #4971: Fix titlecase for characters that are their own
2343 titlecase, but not their own uppercase.
2344
Benjamin Peterson193152c2009-04-25 01:08:45 +00002345- Issue #5283: Setting __class__ in __del__ caused a segfault.
2346
Mark Dickinsonad476da2009-04-23 19:14:16 +00002347- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2348 z involves nans, infs or negative zeros.
2349
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002350- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002351
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002352- Issue #1869 (and many duplicates): make round(x, n) correctly
2353 rounded for a float x, by using the decimal <-> binary conversions
2354 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2355 consistently agrees with format(x, '.2f').
2356
Benjamin Petersonae937c02009-04-18 20:54:08 +00002357- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2358 some builtin types.
2359
Eric Smith0923d1d2009-04-16 20:16:10 +00002360- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2361
Eric Smith35e84722009-04-16 20:21:28 +00002362- Issue #5515: str.format() type 'n' combined with commas and leading
2363 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002364
2365- Implement PEP 378, Format Specifier for Thousands Separator, for
2366 floats.
2367
Mark Dickinson3370cce2009-04-17 22:40:53 +00002368- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002369 1e11, not 1e12. This avoids printing 13 significant digits in
2370 situations where only 12 of them are correct. Example problem
2371 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2372 long time.)
2373
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002374- Issue #1580: On most platforms, use a 'short' float repr: for a
2375 finite float x, repr(x) now outputs a string based on the shortest
2376 sequence of decimal digits that rounds to x. Previous behaviour was
2377 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002378 Another minor difference is that the new repr switches to
2379 exponential notation at 1e16 instead of the previous 1e17; this
2380 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002381
2382 There's a new sys attribute sys.float_repr_style, which takes
2383 the value 'short' to indicate that we're using short float repr,
2384 and 'legacy' if the short float repr isn't available for one
2385 reason or another.
2386
2387 The float repr change involves incorporating David Gay's 'perfect
2388 rounding' code into the Python core (it's in Python/dtoa.c). As a
2389 secondary consequence, all string-to-float and float-to-string
2390 conversions (including all float formatting operations) will be
2391 correctly rounded on these platforms.
2392
Georg Brandl5f90d792010-08-01 22:31:05 +00002393 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002394 this change does not apply.
2395
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002396- Issue #5759: float() didn't call __float__ on str subclasses.
2397
Georg Brandlabc38772009-04-12 15:51:51 +00002398- The string.maketrans() function is deprecated; there is a new static method
2399 maketrans() on the bytes and bytearray classes. This removes confusion about
2400 the types string.maketrans() is supposed to work with, and mirrors the
2401 methods available on the str class.
2402
R. David Murraydc6da8a2009-04-09 22:16:43 +00002403- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2404 its clarity and its speed.
2405
Matthias Klose091c7b12009-04-07 13:24:27 +00002406- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2407 to avoid compiler warnings.
2408
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002409- Issue #3739: The unicode-internal encoder now reports the number of characters
2410 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00002490- Issue #1161031: fix readwrite select flag handling: POLLPRI now
2491 results in a handle_expt_event call, not handle_read_event, and POLLERR
2492 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2493 dispatcher now has an 'ignore_log_types' attribute for suppressing
2494 log messages, which is set to 'warning' by default.
2495
Matthias Klosea3d29e82009-04-07 13:13:10 +00002496- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

2570 untrackable objects are not tracked by the garbage collector. This can
2571 reduce the size of collections and therefore the garbage collection overhead
2572 on long-running programs, depending on their particular use of datatypes.

2588
Eric Smith8ec90442009-03-14 12:29:34 +00002589- Issue #5237: Allow auto-numbered fields in str.format(). For

Lars Gustäbel42e00912009-03-22 20:34:29 +00002642- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2643 forever on incomplete input. That caused tarfile.open() to hang when used
2644 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2645 partial bzip2 compressed data.

2835 kept open but the file object behaves like a closed file. The ``FileIO``
2836 object also got a new readonly attribute ``closefd``.

2846 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2847 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2848 of using the replace error handler in PyUnicode_DecodeUTF8().

3167
Antoine Pitrou08838b62009-01-21 00:55:13 +00003168- Issue #5008: When a file is opened in append mode with the new IO library,
3169 do an explicit seek to the end of file (so that e.g. tell() returns the
3170 file size rather than 0). This is consistent with the behaviour of the
