Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Thomas Wouters 3ffa59b137 Rework channelnumber/samplesize detetion code's output variables a bit to
convince gcc (4.0.x) the variables are never used uninitialized (and raising
a proper exception if they ever are.)

Greg Ward a34b1a0749 Allow the device name to be passed to linuxaudiodev.open(), for
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.

Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

Bugfix candidate.

Martin v. Löwis cdc4451222 Include <unistd.h> in Python.h. Fixes #500924. 2002-01-12 11:05:12 +00:00
Guido van Rossum 146483964e Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this).  Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right.  Apologies if they're
not.  This also touches the weakref docs, which contains a sample type
object initializer.  It also touches the mmap test output, because the
mmap type's repr is included in that output.  It touches object.h to
put the correct description in a comment.

Guido van Rossum 7745218c05 SF patch #489989 (Charles G Waldman) linuxaudiodev.c - fix initialization
The OSS Programmer's Reference (www.4front-tech.com)
states:

*Setting Sampling Parameters

There are three parameters which affect the sound
quality (and therefore memory and bandwidth
requirements) of sampled audio data. These are:

** sample format (sometimes called number of bits)
** number of channels (mono or stereo), and
** sampling rate (speed)

NOTE:

It is important to always set these parameters in the
above order. Setting sampling rate before the number
of channels doesn't work with all devices.

Guido van Rossum f5bd684337 Applying SF patch #412553 by Christopher Lee: fix linuxaudiodev
handling of EAGAIN.

This may or may not fix the problem for me (Mandrake 7.2 on a Dell
Optiplex GX110 desktop): I can't hear the output, but it does pass the
test now.  It doesn't fix the problem for Fred (Mandrake 7.2 on a Dell
Inspiron 7500 which has the Maestro sound drivers).  Fred suspects
that it's the kernel version in combination with the driver.

Guido van Rossum 59316671e3 Be consistent in the description of audio formats: <format> <width>
"audio".

Also add AFMT_S16_NE ("native-endian").  (Somehow there's no AFMT_U16_NE.)

Jeremy Hylton e2b7c4dea3 test_linuxaudio:
read the header from the .au file and do a sanity check
    pass only the data to the audio device
    call flush() so that program does not exit until playback is complete
    call all the other methods to verify that they work minimally
    call setparameters with a bunch of bugs arguments

linuxaudiodev.c:
    use explicit O_WRONLY and O_RDONLY instead of 1 and 0
    add a string name to each of the entries in audio_types[]
    add AFMT_A_LAW to the list of known formats
    add x_mode attribute to lad object, stores imode from open call
    test ioctl return value as == -1, not < 0
    in read() method, resize string before return
    add getptr() method, that calls does ioctl on GETIPTR or GETOPTR
        depending on x_mode
    in setparameters() method, do better error checking and raise
        ValueErrors; also use ioctl calls recommended by Open Sound
        System Programmer's Guido (www.opensound.com)
    use PyModule_AddXXX to define names in module

Barry Warsaw 9bfd2bf5ed Do the absolute minimal amount of modifications to eradicate
Py_FatalError() from module initialization functions.  The importing
mechanism already checks for PyErr_Occurred() after module importation
and it Does The Right Thing.

Unfortunately, the following either were not compiled or tested by the
regression suite, due to issues with my development platform:

	almodule.c
	cdmodule.c
	mpzmodule.c
	puremodule.c
	timingmodule.c

Jeremy Hylton a3895c0d29 This module has a poor name, since it can be used under FreeBSD and
Linux.  Perhaps winaudio would be better, as it would offend both
parties equally.

tg@freebsd.org: allow this module to compile under FreeBSD
(he suggests voxwareaudio)

Barry Warsaw 4ddd8202bc lad_dealloc(): if xp->x_fd == -1, it means the descriptor's already
been closed.  Don't try to reclose it.  Found by Insure.

Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)
