These just clutter the generated documentation, particularly the list of
global variables.

Every .c file includes it anyway.
Consolidate EOF error codes.2023-03-11T18:16:46ZAndre Nollmaan@tuebingen.mpg.de2022-12-30T14:08:59Zurn:sha1:b087c1356e3eebf656aa1c783ff7e50c9de5a229
Currently we have ~15 error codes which indicate an EOF condition. One
should suffice, so drop all codes except the generic E_EOF and use
that everywhere.
Merge topic branch t/overflow into master2022-10-03T16:01:20ZAndre Nollmaan@tuebingen.mpg.de2022-10-03T15:59:56Zurn:sha1:563b56a493d6a2bdcdebafadd907954dbe1de8a8
This series implements a new memory allocation API which checks
for overflows. The first part of the series just renames the main
allocation functions. Later patches in the series implement allocators
which take two size_t arguments (like calloc(3)) and check whether the
multiplication overflows by employing the __builtin_mul_overflow()
primitive supported by gcc and clang. This requires us to bump the
lowest supported gcc and clang version.
* refs/heads/t/overflow:
build: Compile with -ftrapv.
string: Introduce arr_zalloc().
string: Introduce arr_alloc().
string: Introduce arr_realloc() and check for integer overflow.
string: Rename para_calloc() -> zalloc().
string: Rename para_malloc() -> alloc().
string: Overhaul para_strdup().
Rename ->{pre,post}_select methods to ->{pre,post}_monitor.2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-10-10T16:10:09Zurn:sha1:e3a7e12639c34fd86d48a072beb48add8c498d09
The word "monitor" is neutral and continues to be correct after the
switch from select(2) to poll(2).
Pure rename, nothing to see here.
Hide implementation of para_fd_set().2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-10-03T19:52:02Zurn:sha1:bb899fb1a0c279a2890ff30d11bf7aec50fb92ed
This preparatory patch for replacing select() renames para_fd_set()
to sched_fd_set(), moves it to sched.c and makes it static. All
users are modified to call either of the two new public functions
sched_monitor_{read,write}fd() which take a pointer to struct sched
rather than an fd set pointer.
sched: Introduce sched_{read,write}_ok().2022-08-25T13:37:26ZAndre Nollmaan@tuebingen.mpg.de2021-09-30T20:35:10Zurn:sha1:181beb316afad036ac01a778544c5dec0a8d51c7
Two trivial wrappers for FD_ISSET() which hide the fact that we're
still using the select(2) API.
string: Rename para_calloc() -> zalloc().2022-07-29T17:22:09ZAndre Nollmaan@tuebingen.mpg.de2021-11-09T17:41:17Zurn:sha1:26a032fffa6c6e6f092ed3d14c2b5f08e5c736d6
Reword the documentation a bit since the function has never been a
wrapper for calloc(3). No code changes.
Teach writers to abort gracefully on early EOF.2021-10-21T17:53:06ZAndre Nollmaan@tuebingen.mpg.de2021-09-05T18:16:59Zurn:sha1:53bbd5127f8bb9132aa9e252928d748f103d7e4e
For very short streams it may happen that the receiver and decoder
unregister themselves from the buffer tree before the writer had a
chance to query the information from the decoder which it needs to
open the audio device. This leads to errors such as
Aug 25 14:24:51 schubert (5) get_btr_value: cmd sample_rate: Operation not supported
Aug 25 14:24:51 schubert (5) get_btr_value: cmd channels: Operation not supported
Aug 25 14:24:51 schubert (5) get_btr_value: cmd sample_format: Operation not supported
Aug 25 14:24:51 schubert (4) alsa_init: channels count not available: Invalid argument
This may happen with all receivers, audio formats and writers,
although it is most common with ogg streams.
This commit changes get_btr_sample_rate() and friends to return a
standard error code rather than assuming success. The alsa, ao and
oss writers are patched to check the return value and fail gracefully
if one of these functions fails.
