2018-07-24pthreadpool: add pthreadpool_restart_check[_monitor_{fd,drain}]()Stefan Metzmacher1-0/+64
This makes it possible to monitor the pthreadpool for exited worker threads and may restart new threads from the main thread again. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Ralph Boehme <slow@samba.org>
2018-07-24pthreadpool: call unshare(CLONE_FS) if availableRalph Boehme1-0/+17
This paves the way for pthreadpool jobs that are path based. Callers can use pthreadpool_per_thread_cwd() to check if the current pool supports it.

2018-07-12pthreadpool: split out a pthreadpool_stop() from pthreadpool_destroy()Stefan Metzmacher1-0/+26
This can be used in combination with pthreadpool_cancel_job() to implement a multi step shutdown of the pool. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Ralph Boehme <slow@samba.org>

2018-07-12pthreadpool: add pthreadpool_max_threads() and pthreadpool_queued_jobs() helpersStefan Metzmacher1-0/+21
These can be used to implement some kind of flow control in the caller. E.g. unless pthreadpool_queued_jobs() is lower than pthreadpool_max_threads() is good to prepare new jobs. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Ralph Boehme <slow@samba.org>
