so efreet mime was loading a bunch of mime type info files, parsing
them on startup and allocating memory to store all this mime info -
globs, mimetype strings and more. all a big waste of memory as its
allocated on the heap per process where its the SAME data files loaded
every time.
so make an efreet mime cache file and a tool to create it from mime
files. mmap this file with all the hashes/strings in it so all that
data is mmaped once in memory and shared between all processes and it
is only paged in on demand - as actually read/needed so if your
process doesnt need to know about mime stuff.. it wont touch it anyway.
this saves about 240-300k or so of memory in my tests. this has not
covered the mime MAGIC files which still consume memory and are on the
heap. this is more complex so it will take more time to come up with a
nice file format for the data that is nicely mmaped etc.
@optimize
since the conversion from dbus -> ecore-ipc, efreetd has failed to
notify when a cache build has completed, instead only sending the current
state of the desktop cache: not built
fix T2733
@fix
this fixes warnings about no efreet dbus session bus in non session
environments as brought up on the mailing lists with:
Subject: Re: [E-devel] [EGIT] [core/efl] master 01/01: edje: unset
efreet cache update flag to prevent dbus connections
this moves all of efreetd client and server to ecore ipc, with client
auto-launching efreetd if not found as a service and trying for up to
500ms to connect. efreetd times out on last connection or no
connections after 10sec so it wont hang around forever if not in use.
it seems to work in my testing, so let me know if there is an issue.
@fix
