we really should have data inside the loop object, so begin moving it
one small thing at a time. this is the basics that will allow multiple
efl loops. make an eo efl object and class for fd handlers that is efl loop
bound make fd handlers really bound to their parent loop and not global as
well as have a nice class/obj. create an message queue per loop and
put legacy ecore events on top of it... and a lot more.
this is not 100% done, but it's a lot of the core and groundwork.
various ecore_timer_add(), ecore_diler_add() etc. need changes.
The following still need doing:
ecore_timer (internal usage for sure)
ecore_idler (internal usage for sure)
ecore_idle_enterer
ecore_idle_exiter
ecore_pollers? (is the new efl loop stuff ok?)
ecore_exe (fork/spawn from any thread and track exe from that thread?)
ecore_signal code
ecore_throttle (should we have a single global too? we have per loop)
ecore_app ? (should every loop be given its own argv/argc?)
Lots of internal ecore code uses/calls these legacy calls and we
should have efl loop replacements and/or use the ones we have
The following will bedifferently designed for loop to loop
control/messaging/ipc:
ecore_thread
ecore_pipe
During shutdown it is possible that some event are still in ecore events
queue and get processed after the shutdown of the module that did emit them.
This would lead to crash in some case. The answer to this problem is to
normally manually track all ecore event in the queue and destroy them
before shutdown... Of course that make the API difficult to use and
basically nobody got it right.
This new API do actually as it says remove all the ecore event of a
certain type from ecore events queue. It is to be called on shutdown.
@fix
This reverts commit 2c6808e4ee.
this breaks a number of expectations and guarantees in efl:
* causes unexpected event iteration during app startup before main loop begins
- leads to event loss
* causes unexpected event iteration during app shutdown after main loop quits
- leads to invalid memory access
* causes recursive event iteration during event handler callbacks
- leads to ?????????????????????????????????????????????????????????????????
all of these can be easily seen by running enlightenment, and all of these cause
unexpected behaviors in enlightenment including, but not limited to, a lot of crashes
fix T5232
If a component emit Ecore_Event and they aren't processed before the
call it call ecore_shutdown, there is no way to prevent this event
from being triggered after the component at shutdown itself. Which
may well lead to a use after free case. As we don't know which event
are pending and we also are not shuting down ecore completely as they
are still other component using it, we can only flush all pending event
right away.
