- cache_num
and also swiched to wrong type for error status (tested with proper one, than ... "oh wait, we have empty 'i' variable!", later ... "oh sh size_t is uint!")
- protected and unprotected __tostring (protected outside, unprotected internal, avoid double pcall)
- also check userdata for metafields (non simple type)
- mywid and mysid are functions now
- minor api bump
dunno why so many additions and deletions
basic queues, remove cache_set_tables (cache_set will do it now)
extend wsapi with 4th argument without breaking it
don't spawn lua_states on workers, if nothing to run
cache multi_set,update,del also returns number of bad keys
remove atexit, does not work as expected
using prehashed lua_createtable when we can instead of lua_newtable
plugin specific regsiter signal
add_file_monitor, add_timer, add_rb_timer, add_cron, alarm
- lua gc default is now LUA_GCSTEP instead of LUA_GCCOLLECT, the default value of gc-freq 0 with full collection after each request is really overkill. LUA_GCSTEP with default gc-freq works better. But you can always change gc to full collect via 'lua-gc-full = 1' opt;
- if our coroutine yields unexpected nil while in async mode, we retry the coroutine's call again in order to detect dead coroutine without async switch
- and some cleanup
trying to avoid seg_fault on very heavy load; (our workers now alloc memory for states and create it)
also our app can now work without wsapi app, it will just send 500 error code
only ONE lua_State per 1 worker, and one lua thread per one worker's core.
so, 4 workers with 8000 async cores will not create 8000 lua_States, only 4, for each worker.
uwsgi table now also has lua_thread collection, and mywid variable.
Know bugs: too many simultaneously running cores (like async = 8000) without proper gc will cause segmentation fault (out of memory)
I noticed that all cool kids are using uwsgi_malloc instead of malloc;
Also I noticed, that I forgot to free memory last time (while playing on high level languages)
- rpc calls from my lua app ('local str = uwsgi.rpc(node, func_name, arg1, arg2, ...);')
- global "uwsgi.req_input_read" alias of local "env.input.read" function
- can yield numbers as well
- can return nil instead of header's table (same as {})
- can return nil or string (or number) instead of coroutine
