Fix some doxygen comments related to stdin and stdout.

Fix two stdin/stdout related memory leaks.

2025-11-17T16:49:38Z

The moderately recent commit which revamped the stdin/stdout API missed to patch the client code to call the cleanup functions {stdin,stdout}_free() introduced by that commit. Also, both {stdin,stdout}.c missed to remove the buffer tree node in certain cases. The additional btr_remove_node() calls fix this, and they don't hurt since this function is idempotent.

Revamp the stdin/stdout API.

2025-08-27T17:16:54Z

With the current API it is impossible to free the memory that was allocated by stdin_task_register() after schedule() returns. This commit replaces the APIs defined in stdin.h and stdout.h to remove the memory leaks which are inevitable with the old API. We also make struct stdin_task and stdout_task opaque because the API users (client.c, filter.c, recv.c and write.c) should not be able to manipulate the fields of these structures directly. The new stdout API differs from the new stdin API only in that stdout_new() needs an additional argument to let the caller pass in a pointer to the parent buffer tree node. Other than that, the APIs are symmetric. Use the opportunity to do the non-blocking dance in std{in,out}_new() and std{in,out}_free() rather than in the post-monitor functions. This way we may get rid of the silly ->must_set_nonblock_flag boolean of struct std{in,out}_task.

Rename ->{pre,post}_select methods to ->{pre,post}_monitor.

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.

stdin/stdout: Streamline documentation of {pre,post}_select().

Don't state the obvious and avoid talking about fd sets.

Hide implementation of para_fd_set().

2022-08-25T13:37:26Z

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().

2022-08-25T13:37:26Z

Two trivial wrappers for FD_ISSET() which hide the fact that we're still using the select(2) API.

Shorten copyright notice.

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 }'
