a8daa2d683 Signal before unlocking in pool.c 2018-11-08 10:45:53 -08:00

fbd5dfc1b1 changed POOL_resize() return type to int 
return is now just en error code.
This guarantee that `ctx` remains valid after POOL_resize().
Gets rid of internal POOL_free() operation.

243cd9d8bb add a cond_broadcast after resize 
to make sure all threads (notably newly available threads)
get awaken to immediately process potential items in the queue.

818e72b4d5 added extended POOL test 
abrupt end + downsizing with running jobs remaining in queue.

also : POOL_resize() requires numThreads >= 1

6de249c1c6 fixed: bug when counting nb of active threads 
when queueSize > 1

also : added a test in testpool.c
       verifying resizing is effective.

6b48eb12c0 change control of threadLimit

166901dc72 reduced POOL_resize() restriction 
It's not necessary to ensure that no job is ongoing.
The pool is only expanded, existing threads are preserved.
In case of error, the only option is to return NULL and terminate the thread pool anyway.

4567c57199 finalized POOL_resize() 
POOL_ctx* POOL_resize(POOL_ctx* ctx, size_t numThreads)

The function may fail, and returns a NULL pointer in this case.

86b4fe5b45 adjustCParams : restored previous behavior 
unknowns srcSize presumed small if there is a dictionary (dictSize>0)
and presumed large otherwise.
