paraslash/prebuffer_filter.c, branch master

Switch to SPDX identifiers.

2026-03-17T22:45:43Z

Generated with sed -i 's|Copyright.*Andre Noll.*|SPDX-License-Identifier: GPL-2.0 */|g' *.c *.h followed by manually tweaking the result a bit. No license change intended.

doxygen: Hide user_data variables.

2025-10-08T18:58:23Z

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

Include regex.h from para.h.

2025-05-19T17:35:58Z

Every .c file includes it anyway.

Merge topic branch t/overflow into master

2022-10-03T16:01:20Z

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.

2022-08-25T13:37:26Z

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.

string: Rename para_calloc() -> zalloc().

2022-07-29T17:22:09Z

Reword the documentation a bit since the function has never been a wrapper for calloc(3). No code changes.

prebuffer: Remove buffer tree node on errors.

2021-04-12T13:16:52Z

When the ->post_select method of a filter returns negative, it *must* remove its buffer tree node as well. The prebuffer missed to do that, which results in a stale reference to the buffer tree which keeps the audiod slot busy. When no more slots are free, audiod hangs or exits with a "no more free slots" message. This patch avoids this.

prebuffer: Bail out on bufffer tree errors.

2021-01-01T15:05:56Z

Without this, the prebuffer filter might stay active forever, occupying a slot of para_audiod until no more slots are available. This was observed with the udp receiver.

Avoid audiod hangs when prebuffer filter is active.

2020-06-17T16:36:17Z

This filter misses to honor task notifications. As a result of this omission, when CTRL+C is pressed while audiod is running in foreground mode and the prebuffer filter is active, the audiod process hangs. The fix is obvious.

Shorten copyright notice.

2017-09-22T14:35:22Z

The GPLv2 line does not add any additional information, so drop it. This leaves a single line of legalese text for most files, which is about the amount of screen real estate it deserves. This patch was created with the following script (plus some manual fixups): awk '{ if (NR <= 5) { gs = gensub(/.*Copyright.* ([0-9]+).*Andre Noll.*/, "\\1", "g") if (gs != $0) year = gs next } if (NR == 6 && year != "") printf("/* Copyright (C) %s Andre Noll , see file COPYING. */\n", year) print }'
