Changes asserts on the reference count of objects to assert the value
after KVZ_ATOMIC_INC instead of directly checking the value. Fixes some
data races detected by TSan.
Changes thread queue so that only the jobs that are ready to run are
stored in the queue. Other jobs are kept track of by pointers in the
reverse dependency lists of other jobs. When a job is ready to run it is
appended to the queue. The job queue is stored as a linked list.
The definitions of threadqueue_queue_t and threadqueue_job_t are moved
to the .c file, turning them into opaque structs.
Makes thread queue code simpler. Fixes some TSan errors.
Drop pthread_cond_broadcast on threadqueue->cond in function
kvz_threadqueue_waitfor. The broadcast caused threads to be woken up
more often than necessary.
Changes kvazaar_close to stop all threads before freeing encoder states.
Fixes a crash when the encoder is closed before all pictures have been
encoded.
Fixes the order of acquiring locks for the job and its dependency in
kvz_threadqueue_job_dep_add. The dependency is locked before the job
that depends on it. This is the same order as in threadqueue_worker.
Acquiring the locks in different order in kvz_threadqueue_job_dep_add
and threadqueue_worker would sometimes result in a deadlock.
Both the thread queue and the encoder states hold pointers to the thread
queue jobs. It is possible that a job is removed from the thread queue
and freed while the encoder state is still using it. This commit adds
reference counting to threadqueue_job_t in order to fix the problem.
Fixes#161.
The includes should make more sense now and not just happen to compile
due to headers included from other headers.
Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.
include-what-you-use 0.7 (git:b70df35)
based on clang version 3.9.0 (trunk 264728)
The main thread has to wait for the worker threads to finish. The
pthread_cond_timedwait call used to accomplish this was given
a relative instead of absolute time, which resulted in the call
returning immediately, because the time had already passed.
This removes the now unnecessary sleeps and fixes the time given to
the pthread_cond_timedwait such that it now waits until a job finishes
or 100ms have passed.
- Everyone who has contributed code to the project has been asked to license
their contributions under LPGL and they have agreed.
- COPYING file changed to say LGPLv2.1 instead of GPLv2.
- GPL changed to LGPL in the header of every single file that a header and
header added to the few that were missing one.
- Also.. Happy new year!
