* Rework channelnumber/samplesize detetion code's output variables a bit toThomas Wouters2006-03-011-7/+6
| | | | | convince gcc (4.0.x) the variables are never used uninitialized (and raising a proper exception if they ever are.)

* Allow the device name to be passed to linuxaudiodev.open(), forGreg Ward2002-11-271-7/+19
| | | | | | | | | | | | 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.
* staticforward bites the dust.Jeremy Hylton2002-07-171-1/+1
| | | | | | | | | | | | | | | 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.
* Repair widespread misuse of _PyString_Resize. Since it's clear peopleTim Peters2002-04-271-2/+1
| | | | | | | | | | | | | | | | | | | | | | 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.
* Include <unistd.h> in Python.h. Fixes #500924.Martin v. Löwis2002-01-121-4/+0

* Patch supplied by Burton Radons for his own SF bug #487390: ModifyingGuido van Rossum2001-12-081-1/+1
| | | | | | | | | | | | | 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.
* SF patch #489989 (Charles G Waldman) linuxaudiodev.c - fix initializationGuido van Rossum2001-12-081-9/+8
| | | | | | | | | | | | | | | | | | | | | 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.
* Applying SF patch #412553 by Christopher Lee: fix linuxaudiodevGuido van Rossum2001-04-021-9/+29
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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

* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-1/+1
| | | | | | | | | | | | | | | | | | 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 ;)

* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-2/+2
| | | | | | | | | | 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.)
