what is happening is that a file gets announced through eio_model
listing code, at this point of time, the monitor does not yet know about
the file. If the file now gets deleted between the annoncing and the
learning of the file from the monitor, then the file got an ADD event,
but no DEL event. Which is a bug.
With this commit there is a new API which asks the monitor if the file
already has the knowledge about the files existance, or not. A few
monitors like win32 inotify or cocoa do not have context about the file
directly, if the OS is now having the same bug, then we are again in
trouble, however, we canot do anything about that. In the case of kevent
or poll, this asks the context of the monitor if the file is already
there.

do it once and remember the result from the first one. drops overhead
for sure by a chunk i actually could see in perf reports like about 1-2%
of cpu...
This fixes cycles of init/shutdown/init where ecore event types would
become invalid, since they are now stored in a dynamic array rather than
a statically stored array.
The risk here is that if a module of EFL tends to init/shutdown in a
"normal" scenario then the event type array will grow in a leaking
manner. This could be fixed by resetting those event ID's only when the
loop actually exits (EFL_EVENT_DEL on the main loop). I'm not using
EFL_EVENT_DEL in this patch as this would add too many event callbacks
to the main loop object, which may result in slightly slower event calls
to it, affecting the overall performance.
Fix race condition when touching/changing a (theme) file often.
An Eio_Monitor was marked as "delete_me" but the rename callback
was still called, leading to memory access to already freed
objects.
Test protocol was:
ELM_THEME=~/default.edj elementary_test &
watch touch ~/default.edj
this MIGHT fix T45 but i can't reproduce to confirm, but reading a
backtrace indicates this could have been the issue. it looks like
there is room for a dangling pointer anyway, so fix.
stable release - cherry-pick me!
