Obtain cleaner coding and a system wide
performance boost by using the fast, pre-parsed
PyArg_Unpack function instead of PyArg_ParseTuple
function which is driven by a format string.
This can cause core dumps when Python runs. Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions. This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.
operands have identical tzinfo members (meaning object identity -- "is").
I misunderstood the intent here, reading wrong conclusion into
conflicting clues.
be trusted with years before 1900, so now we raise ValueError if a date or
datetime or datetimetz .strftime() method is called with a year before
1900.
such that the datetime tests failed if the envar PYTHON2K was set.
This is an utter mess, and the datetime module's strftime functions
inherit it. I suspect that, regardless of the PYTHON2K setting, and
regardless of platform limitations, the datetime strftime wrappers
will end up delivering nonsense results (or bogus exceptions) for
any year before 1900. I should probably just refuse to accept years
earlier than that -- else we'll have to implement strftime() by hand.
{timetz,datetimetz}.{utcoffset,dst}() now return a timedelta (or None)
instead of an int (or None).
tzinfo.{utcoffset,dst)() can now return a timedelta (or an int, or None).
Curiously, this was much easier to do in the C implementation than in the
Python implementation (which lives in the Zope3 code tree) -- the C code
already had lots of hair to extract C ints from offset objects, and used
C ints internally.
used that.
wrap_strftime(): Removed the most irritating uses of buf.
TestDate.test_ordinal_conversions(): The C implementation is fast enough
that we can afford to check the endpoints of every year. Also added
tm_yday tests at the endpoints.
PyMapping_Check() doesn't guarantee that PyMapping_Size() won't raise
an exception, nor that keys and values are lists.
Also folded some long lines and did a little whitespace normalization.
Probably a 2.2 backport candidate.
* rename oss_t to lad_t, Ladtype to OSSType,
* rename lad_*() methods to oss_*()
* rename lad_methods list to oss_methods
Patch and impetus supplied by Nicholas FitzRoy-Dale <wzdd@lardcave.net>.
Use OSSAudioError much less frequently -- all real I/O errors (ie. any
time open(), read(), write(), ioctl(), or select() return an error)
become IOError. OSSAudioError is only used now for bad open() mode.
Added _EXPORT_INT macro to export an integer constant to Python-space.
Use it for all the AFMT_* constants, and update the list of AFMT_*
constants to match what's in Linux 2.4: add AFMT_{QUERY,IMA_ADPCM,
MPEG,AC3}. This should probably be tested with older versions of OSS,
eg. with Linux 2.2 and 2.0.
Export all SNDCTL_* ioctl numbers (where "all" is the set found in
/usr/include/linux/soundcard.h on my Debian 3.0 system -- again
Linux 2.4). Again needs to be tested with older OSS versions.
it impossible to access blocking mode!
* Rename write() to writeall(), and add a write() method that just
does one write().
* Rearrange/simplify writeall(): in particular, don't supply a timeout
to select(). Let it block forever if it has to.
* Add a bunch of simple ioctl() wrappers: nonblock(), setfmt(),
getfmts(), channels(), speed(), sync(), reset(), post(). These
wrap, respectively, SNDCTL_DSP_NONBLOCK, SNDCTL_DSP_SETFMT,
SNDCTL_DSP_GETFMTS, etc.
* Reduce flush() (which was a wrapper for the SNDCTL_DSP_SYNC ioctl) to
an alias for sync().
* Rearrange the lad_methods list to reflect the order in which the
methods are defined, and add some grouping comments.
This module is a replacement for linuxaudiodev, which will eventually
be deprecated.
Initial revision is rev 2.20 of linuxaudiodev.c, with a rewritten
header comment.
consistency with the built-in open() (and every other sane open()
function, for that matter). The two valid ways to call this open() are
now open(mode) and open(device, mode).
For backwards compatibility, retain the old open(mode) calling syntax --
this makes the error message when you call open(device) a bit confusing,
but oh well.
This is the first half of SF patch #644977.
This bug happened because: 1) the scanner_search and scanner_match methods
were not checking the buffer limits before increasing the current pointer;
and 2) SRE_SEARCH was using "if (ptr == end)" as a loop break, instead of
"if (ptr >= end)".
* Modules/_sre.c
(SRE_SEARCH): Check for "ptr >= end" to break loops, so that we don't
hang forever if a pointer passing the buffer limit is used.
(scanner_search,scanner_match): Don't increment the current pointer
if we're going to pass the buffer limit.
* Misc/NEWS
Mention the fix.
Make keyname raise ValueError if passed -1, avoiding a segfault
Make getkey() match the docs and raise an exception in nodelay mode
The return type of getch() is int, not chtype
from Greg Chapman.
* Modules/_sre.c
(lastmark_restore): New function, implementing algorithm to restore
a state to a given lastmark. In addition to the similar algorithm used
in a few places of SRE_MATCH, restore lastindex when restoring lastmark.
(SRE_MATCH): Replace lastmark inline restoring by lastmark_restore(),
function. Also include it where missing. In SRE_OP_MARK, set lastindex
only if i > lastmark.
* Lib/test/re_tests.py
* Lib/test/test_sre.py
Included regression tests for the fixed bugs.

On HPUX, Solaris, Tru64 (Dec UNIX), and IRIX (I think),
O_NONBLOCK is the POSIX version of non-blocking I/O
which is what we want.
On Linux and FreeBSD (at least), O_NONBLOCK and O_NDELAY are the same.
So this change should have no negative effect on those platforms.
Tested on Linux, Solaris, HPUX.
Thanks to Anders Qvist for diagnosing this problem.
XML_Parser, which happens to be a pointer type, not an XML_Parser*.
This generated warnings when compiled with Expat 1.95.5, which no
longer defines XML_Parser to be void*.
64bit, big endian (issue 2 only).
This adds a bunch of memcpy calls via a temporary variable to avoid
alignment errors. That's needed for some platforms.
the "safety" parentheses since some older compilers refuse to compile
the module then, claiming that static initializers are non-constant.
This doesn't actually make any difference for Python, since these
definitions are not used when compiling with a version of Python that
already defines the PyDoc_* macros.
-- replace then with slightly faster PyObject_Call(o,a,NULL). (The
difference is that the latter requires a to be a tuple; the former
allows other values and wraps them in a tuple if necessary; it
involves two more levels of C function calls to accomplish all that.)
[ 587993 ] SET_LINENO killer
Remove SET_LINENO. Tracing is now supported by inspecting co_lnotab.
Many sundry changes to document and adapt to this change.
