dt_pthread_cond_wait()

static int dt_pthread_cond_wait ( pthread_cond_t *  cond, dt_pthread_mutex_t *  mutex  )

inlinestatic

Wait on cond, releasing mutex for the duration.

Warning

mutex must be held EXACTLY ONCE by the calling thread. Mutexes from dt_pthread_mutex_init(..., NULL) are recursive, and pthread_cond_wait() releases a mutex once regardless of how deep the caller holds it: waiting at depth > 1 leaves it held, so no other thread can take it to signal, and the wait never returns. POSIX calls this undefined; in practice it is a silent hang.

Every wait in this tree takes its mutex at the top of a loop and waits at depth 1, which is the shape this is safe in. If you ever need to wait from inside a nested critical section, unwind to depth 1 first – do not add a "recursive wait".

dt_pthread_mutex_init()

static int dt_pthread_mutex_init ( dt_pthread_mutex_t *  mutex, const pthread_mutexattr_t *  mutexattr  )

inlinestatic

Initialise a mutex. With mutexattr NULL – which is how 54 of the 56 call sites in this tree spell it – the mutex is RECURSIVE.

A thread re-entering a lock it already holds cannot race itself: while it holds the lock no other thread is inside the critical section, so the data it protects is as safe at depth 2 as at depth 1. What a non-recursive mutex does in that situation is deadlock – turning a harmless nesting into a frozen application, which is a worse outcome than the thing it is meant to prevent.

The codebase had already reached that conclusion one lock at a time: darktable.c makes the exiv2 mutex recursive so "a public exif function can hold it across its whole critical section while inner helpers or re-entrant calls re-lock it without deadlocking." This makes it the default instead of a per-lock rediscovery.

Parameters

mutex	the mutex to initialise.
mutexattr	NULL for the recursive default, or an explicit attribute to override it.

Warning

Recursion is NOT free of consequence, and there is exactly one place it bites: pthread_cond_wait() releases the mutex ONCE. A thread that waits while holding a recursive mutex at depth > 1 therefore never releases it and the wait cannot be signalled – POSIX calls the combination undefined. At depth 1 it behaves exactly as before. The eight cond-wait sites in this tree all take their mutex once at the top of a wait loop; see dt_pthread_cond_wait() below, which repeats this where it would be noticed.

Note

Recursion also hides a real class of bug that a deadlock would have exposed: a function that breaks an invariant, then calls something that re-enters and reads the half-updated state. That trade is deliberate – a rare, quiet correctness risk in place of a frequent, total hang.
