dt_exiv2_threadsafe_mutex()

dt_pthread_mutex_t * dt_exiv2_threadsafe_mutex

(

void

)

Exiv2 readMetadata() was not thread-safe prior to 0.27.

dt_pipeline_threadsafe_mutex()

dt_pthread_mutex_t * dt_pipeline_threadsafe_mutex

(

void

)

Prevents concurrent export/thumbnail pipelines from running at the same time. This buys no throughput – the CPU is the bottleneck and the pixel code is already multi-threaded internally through OpenMP – it bounds peak memory instead.

dt_plugin_threadsafe_mutex()

dt_pthread_mutex_t * dt_plugin_threadsafe_mutex

(

void

)

Serializes plugin calls that are not thread-safe, notably at export time when several pipelines would otherwise enter the same library concurrently.

dt_readfile_mutex()

dt_pthread_mutex_t * dt_readfile_mutex

(

void

RawSpeed readFile() is apparently not thread-safe.
