19 written by Charles-Francois Natali.
20
Victor Stinner451385d2011-03-21 03:22:50 +010021- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
22 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
23 (length bigger than 2^31-1 bytes).
24
Antoine Pitrou7983d332011-03-09 12:34:41 +010025- Issue #11450: Don't truncate hg version info in Py_GetBuildInfo() when

44
Mark Dickinson0169af12010-12-04 13:04:18 +000045- Issue #10596: Fix float.__mod__ to have the same behaviour as
46 float.__divmod__ with respect to signed zeros. -4.0 % 4.0 should be

Antoine Pitrou877766d2011-03-19 17:00:37 +0100106- Issue #11459: A ``bufsize`` value of 0 in subprocess.Popen() really creates
107 unbuffered pipes, such that select() works properly on them.
108
Antoine Pitrou5e981412011-03-17 22:38:37 +0100109- Issue #5421: Fix misleading error message when one of socket.sendto()'s

111
R David Murrayde912762011-03-16 18:26:23 -0400112- Issue #11401: fix handling of headers with no value; this fixes a regression

114
R David Murray6d94bd42011-03-16 15:52:22 -0400115- Issue #9298: base64 bodies weren't being folded to line lengths less than 78,
116 which was a regression relative to Python2. Unlike Python2, the last line

Antoine Pitrou2c50a092011-03-15 21:02:59 +0100123- Issue #11501: disutils.archive_utils.make_zipfile no longer fails if zlib is
124 not installed. Instead, the zipfile.ZIP_STORED compression is used to create
125 the ZipFile. Patch by Natalia B. Bidart.
126
briancurtin94eceeb2011-03-14 15:35:35 -0400127- Issue #11491: dbm.error is no longer raised when dbm.open is called with
128 the "n" as the flag argument and the file exists. The behavior matches
129 the documentation and general logic.
Victor Stinner628225c2011-03-21 02:38:51 +0100130
Mark Dickinson37a79fb2011-03-12 11:12:52 +0000131- Issue #11131: Fix sign of zero in decimal.Decimal plus and minus

149 32-bit Windows.
150
R. David Murray43b2f452011-02-11 03:13:19 +0000151- email.header.Header was incorrectly encoding folding white space when
152 rfc2047-encoding header values with embedded newlines, leaving them
153 without folding whitespace. It now uses the continuation_ws, as it
154 does for continuation lines that it creates itself.
155
Georg Brandlf6c8fd62011-02-25 09:48:21 +0000156- Issue #10360: In WeakSet, do not raise TypeErrors when testing for

167 Patch by Stan Mihai.
168
Ned Deily7a8e21a2011-01-29 23:34:19 +0000169- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
170 preventing a confusing hung appearance on OS X with the windows
171 obscured.
172
Ned Deily26d55ed2011-01-29 19:22:26 +0000173- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save
174 commands.
175
Raymond Hettingerd62522a2011-01-27 00:12:08 +0000176- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
177 conversion.
178
Ned Deilyab5dd002011-01-24 22:22:06 +0000179- Issue #10974: IDLE no longer crashes if its recent files list includes files
180 with non-ASCII characters in their path names.

Vinay Sajipeb9d5ad2011-01-21 23:35:57 +0000184- Issue #10949: Improved robustness of rotating file handlers.
185
Antoine Pitrou6107a4e2011-01-20 21:11:13 +0000186- Issue #10955: Fix a potential crash when trying to mmap() a file past its
187 length. Initial patch by Ross Lagerwall.
188
Antoine Pitrou710e9662011-01-19 15:26:37 +0000189- Issue #10898: Allow compiling the posix module when the C library defines
190 a symbol named FSTAT.
191
Antoine Pitroufb7bc3d2011-01-15 16:18:37 +0000192- Issue #10916: mmap should not segfault when a file is mapped using 0 as
193 length and a non-zero offset, and an attempt to read past the end of file
194 is made (IndexError is raised instead). Patch by Ross Lagerwall.
195
Raymond Hettingerd2b03e12011-01-12 23:52:40 +0000196- Issue #10899: No function type annotations in the standard library.

202 node twice.
203
R. David Murray389af002011-01-09 02:48:04 +0000204- Issue #5871: email.header.Header.encode now raises an error if any
205 continuation line in the formatted value has no leading white space
206 and looks like a header. Since Generator uses Header to format all
207 headers, this check is made for all headers in any serialized message
208 at serialization time. This provides protection against header
209 injection attacks.
210
Antoine Pitrouff173852011-01-06 18:29:05 +0000211- Issue #7858: Raise an error properly when os.utime() fails under Windows

224 file descriptors (0, 1, 2) are closed in the parent process. Initial
225 patch by Ross Lagerwall.
226
Éric Araujoe788ace2011-03-21 00:01:23 +0100227- Issue #10753 - Characters ';', '=' and ',' in the PATH_INFO environment
228 variable won't be quoted when the URI is constructed by the wsgiref.util's
Senthil Kumarane5f8e842010-12-29 06:29:58 +0000229 request_uri method. According to RFC 3986, these characters can be a part of
230 params in PATH component of URI and need not be quoted.
231

236
R. David Murray6cb252f2010-12-26 22:24:54 +0000237- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
238 it now prints the filename, line number, and traceback to stderr and skips
239 the rest of that individual file, instead of stopping processing entirely.
240
R. David Murray30f9c8c2010-12-21 21:57:54 +0000241- Issue #4871: The zipfile module now gives a more useful error message if

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

978 witnessed in test_httpservers.
979
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000980- Issue #8524: When creating an SSL socket, the timeout value of the
981 original socket wasn't retained (instead, a socket with a positive timeout
982 would be turned into a non-blocking SSL socket).
983
Antoine Pitrouec146182010-04-24 21:30:20 +0000984- Issue #5103: SSL handshake would ignore the socket timeout and block
985 indefinitely if the other end didn't respond.
986
987- The do_handshake() method of SSL objects now adjusts the blocking mode of
988 the SSL structure if necessary (as other methods already do).

2030 arguments for strings with a space in them.
2031
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00002032- collections.namedtuple() was not working with the following field
2033 names: cls, self, tuple, itemgetter, and property.
2034
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002035- In unittest, using a skipping decorator on a class is now equivalent to
2036 skipping every test on the class. The ClassTestSuite class has been removed.
2037
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002038- Issue #6050: Don't fail extracting a directory from a zipfile if
2039 the directory already exists.
2040
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002041- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2042 than an int, which makes some operations possible under 64-bit Linux (e.g.
2043 DN_MULTISHOT with F_NOTIFY).
2044
Antoine Pitrou716c4442009-05-23 19:04:03 +00002045- Issue #5761: Add the name of the underlying file to the repr() of various

2050
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00002051- Issue #1983: Fix functions taking or returning a process identifier to use
2052 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2053 a process identifier type wider than the standard C integer type.
2054
R. David Murray87e20742009-05-23 01:30:26 +00002055- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +00002065- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
2066
Antoine Pitroue4501852009-05-14 18:55:55 +00002067- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2068 library. This means, for example, that opening an UTF-16 text file in
2069 append mode doesn't add a BOM at the end of the file if the file isn't
2070 empty.
2071
R. David Murray74b89242009-05-13 17:33:03 +00002072- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

2074 corrects a pydoc regression.
2075
Georg Brandl442d3b32010-08-01 22:33:12 +00002076- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00002077 now it does. This also means getfp method now returns the real fp.
2078
Benjamin Peterson932073a2009-05-23 16:14:33 +00002079Installation
2080------------
2081
2082- Issue #6047: fullinstall has been removed because Python 3's executable will
2083 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00002084

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00002118*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00002119
2120Core and Builtins
2121-----------------
2122
Mark Dickinson865e01a2009-05-07 16:37:01 +00002123- Issue #5914: Add new C API function PyOS_string_to_double, and
2124 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2125
Eric Smith741191f2009-05-06 13:08:15 +00002126- Issue #3382: float.__format__, complex.__format__, and %-formatting
2127 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2128 affects nan -> NAN and inf -> INF.
2129
Mark Hammond5a607a32009-05-06 08:04:54 +00002130- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2131 in all operations, including splitdrive, split, etc. splitunc() now issues
2132 a PendingDeprecation warning.
2133
Eric Smith63376222009-05-05 14:04:18 +00002134- Issue #5920: For float.__format__, change the behavior with the
2135 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2136 to be like 'g' but with at least one decimal point and with a
2137 default precision of 12. Previously, the behavior the same but with
2138 a default precision of 6. This more closely matches str(), and
2139 reduces surprises when adding alignment flags to the empty
2140 presentation type. This also affects the new complex.__format__ in
2141 the same way.
2142
Martin v. Löwis011e8422009-05-05 04:43:17 +00002143- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2144
R. David Murrayb18500d2009-05-04 22:59:07 +00002145- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2146 shadowed by classtype's, even if it was None. property now
2147 inserts the __doc__ into the subclass instance __dict__.
2148
Antoine Pitrou244651a2009-05-04 18:56:13 +00002149- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2150 sequences. Patch by Nick Barnes and Victor Stinner.
2151
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002152- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002153
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002154- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2155 received a new method, detach(). detach() disconnects the underlying stream
2156 from the buffer or text IO and returns it.
2157
Mark Dickinson33841c32009-05-01 15:37:04 +00002158- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2159 floats with absolute value over 1e50. Also remove length
2160 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2161 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002162
Eric Smith741191f2009-05-06 13:08:15 +00002163- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002164 format(complex(1, 2./3), '.5') now produces a sensible result.
2165
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002166- Issue #5864: Fix empty format code formatting for floats so that it
2167 never gives more than the requested number of significant digits.
2168
Eric Smith6dc46f52009-04-27 20:39:49 +00002169- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2170 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2171
Eric Smithcc32a112009-04-26 21:35:14 +00002172- Issue #5835: Deprecate PyOS_ascii_formatd.
2173
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002174- Issue #4971: Fix titlecase for characters that are their own
2175 titlecase, but not their own uppercase.
2176
Benjamin Peterson193152c2009-04-25 01:08:45 +00002177- Issue #5283: Setting __class__ in __del__ caused a segfault.
2178
Mark Dickinsonad476da2009-04-23 19:14:16 +00002179- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2180 z involves nans, infs or negative zeros.
2181
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002182- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002183
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002184- Issue #1869 (and many duplicates): make round(x, n) correctly
2185 rounded for a float x, by using the decimal <-> binary conversions
2186 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2187 consistently agrees with format(x, '.2f').
2188
Benjamin Petersonae937c02009-04-18 20:54:08 +00002189- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2190 some builtin types.
2191
Eric Smith0923d1d2009-04-16 20:16:10 +00002192- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2193
Eric Smith35e84722009-04-16 20:21:28 +00002194- Issue #5515: str.format() type 'n' combined with commas and leading
2195 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002196
2197- Implement PEP 378, Format Specifier for Thousands Separator, for
2198 floats.
2199
Mark Dickinson3370cce2009-04-17 22:40:53 +00002200- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002201 1e11, not 1e12. This avoids printing 13 significant digits in
2202 situations where only 12 of them are correct. Example problem
2203 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2204 long time.)
2205
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002206- Issue #1580: On most platforms, use a 'short' float repr: for a
2207 finite float x, repr(x) now outputs a string based on the shortest
2208 sequence of decimal digits that rounds to x. Previous behaviour was
2209 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002210 Another minor difference is that the new repr switches to
2211 exponential notation at 1e16 instead of the previous 1e17; this
2212 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002213
2214 There's a new sys attribute sys.float_repr_style, which takes
2215 the value 'short' to indicate that we're using short float repr,
2216 and 'legacy' if the short float repr isn't available for one
2217 reason or another.
2218
2219 The float repr change involves incorporating David Gay's 'perfect
2220 rounding' code into the Python core (it's in Python/dtoa.c). As a
2221 secondary consequence, all string-to-float and float-to-string
2222 conversions (including all float formatting operations) will be
2223 correctly rounded on these platforms.
2224
Georg Brandl442d3b32010-08-01 22:33:12 +00002225 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002226 this change does not apply.
2227
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002228- Issue #5759: float() didn't call __float__ on str subclasses.
2229
Georg Brandlabc38772009-04-12 15:51:51 +00002230- The string.maketrans() function is deprecated; there is a new static method
2231 maketrans() on the bytes and bytearray classes. This removes confusion about
2232 the types string.maketrans() is supposed to work with, and mirrors the
2233 methods available on the str class.
2234
R. David Murraydc6da8a2009-04-09 22:16:43 +00002235- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2236 its clarity and its speed.
2237
Matthias Klose091c7b12009-04-07 13:24:27 +00002238- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2239 to avoid compiler warnings.
2240
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002241- Issue #3739: The unicode-internal encoder now reports the number of characters
2242 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00002320- Issue #1161031: fix readwrite select flag handling: POLLPRI now
2321 results in a handle_expt_event call, not handle_read_event, and POLLERR
2322 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2323 dispatcher now has an 'ignore_log_types' attribute for suppressing
2324 log messages, which is set to 'warning' by default.
2325
Matthias Klosea3d29e82009-04-07 13:13:10 +00002326- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

2398
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002399- Issue #4688: Add a heuristic so that tuples and dicts containing only
2400 untrackable objects are not tracked by the garbage collector. This can
2401 reduce the size of collections and therefore the garbage collection overhead
2402 on long-running programs, depending on their particular use of datatypes.

2418
Eric Smith8ec90442009-03-14 12:29:34 +00002419- Issue #5237: Allow auto-numbered fields in str.format(). For

2471
Lars Gustäbel42e00912009-03-22 20:34:29 +00002472- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2473 forever on incomplete input. That caused tarfile.open() to hang when used
2474 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2475 partial bzip2 compressed data.
2476
Mark Dickinson79f52032009-03-17 23:12:51 +00002477- Issue #2110: Add support for thousands separator and 'n' type

2592 flag to work properly. Furthermore, when specifying -u, the text stdout
2593 and stderr streams have line-by-line buffering enabled (the default being
2594 to buffer arbitrary chunks of data).
2595
Raymond Hettinger35631532009-01-09 03:58:09 +00002596- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2666 object also got a new readonly attribute ``closefd``.

2676 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2677 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2678 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00003235- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3236 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3237 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3238 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003241 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003242 from test support, which does the conversion.
