Hash :dcfb19a2 Message :Debug mode option to error on evthread init AFTER other event calls.
- A handy event_enable_debug_mode() feature which will error and abort the
application if any thread-aware libevent functions are called BEFORE the
evthread API has been initialized (manually, or through
evthread_use_windows_threads() / evthread_use_pthreads()
- This is done by setting the global debug variable
'event_debug_created_threadable_ctx_' whenever the following functions
are called:
evthreadimpl_lock_alloc_()
evthreadimpl_cond_alloc_()
event_base_new_with_config() <- this checks to see if the thread
callbacks are enabled first, so we
have to manually set the variable.
- Example:
int main(int argc, char ** argv) {
struct event_base * base;
event_enable_debug_mode();
base = event_base_new();
evthread_use_pthreads();
return 0;
}
When executed, the program will throw an error and exit:
[err] evthread initialization must be called BEFORE anything else!
