Ondřej Surý	f23bdc29ef	Document the current default stack sizes on different systems ... The default stack sizes varies between operating systems and between different system libc libraries from 128kB (Alpine Linux with MUSL) to 8M (Linux with glibc). Document the different values used to justify the value of THREAD_MINSTACKSIZE (currently set to 1MB).	2025-08-05 10:46:09 +02:00
Ondřej Surý	96dad96ae5	Add support for setting thread stack size ... When running the isc_quota unit test with less than usual amount of RAM (e.g. in a CI for architectures with 32 bits of address space), the pthread_create() function fails with the "Resource temporarily unavailable (11):" error code. Add functions to get and set the thread stack size (if requested), and use these to set the thread stack size to smaller value in the isc_quota unit test.	2025-08-05 10:46:09 +02:00
Ondřej Surý	4917ffa61b	Explicitly create and shutdown the call_rcu_thread ... As the default_call_rcu_thread can't be forced to flush all the work during the executable shutdown, create one call_rcu_thread explicitly and assign it to the all created threads. This allows this explicit call_rcu_thread to be unassociated from the main thread and freed before the executable destructor exits.	2025-02-22 16:19:01 +01:00
