be way too big to ever allocate. probably code can do with other fixes too.
also make jpeg loader rudametarily understand load regions. very brute-force.
but enough for just this moment to do testing.

none (ie default) and the engines actually understand it and use it.
2. fixes to scalecache and cserver too. more toto's done and its now been
stress tested by me - and i think cserve is ready to go gold. just enable it
with export EVAS_CSERVE=1 in your env for any eflapps - and run evas_cserve
(cmd-line options avalable plus cmd-line tol to query settings change on the
fly and query statsitics and state)
SVN revision: 40536
is it ok?
1. it can be --disabled in evas's configure, but i think it works WITHOUT
disabling it (runtime) as it falls back to the old way of loading
2. it may cause build problems on some platforms - without it being enabled
we won't find out, so enable.
3. it needs enabling runtime to make use of it so it should be safe for now
until you enable it.
what is it?
it is a SHARED cache server - that means images loaded are loaded BY the
cache server (not by the actual process using evas). images are shared via
shared memory segments (shm_open + mmap). this means only 1 copy is in all
ram at any time - no matter how many processes need it , and its only loaded
once. also if another app has already loaded the same data - and its in the
cache or active hash, then another process needing the same stuff will avoid
the loads as it will just get instant replies from the cache of "image already
there". as it runs in its own process it can also time-out images from the
cache too.
right now you enable it by doing 2 things
1. run evas_cserve (it has cmd-line options to configure cache etc.
2. export EVAS_CSERVE=1 (im the environment of apps that should use the cache
server).
it works (for me) without crashes or problems. except for the following:
1. preloading doesnt work so its disabled if cserve is enabled. thisis
because the load threads interfere withthe unix comms socket causing
problems. this need to really change and have the cserve know about/do
preload and let the select() on the evas async events fd listen for the
unsolicited reply "load done". but it's not broken - simple preloads are
syncronous and forced if cserve is enabled (at build time).
2. if cserve is killed/crashes every app using it will have a bad day. baaad
day. so dont do it. also cserve may be vulnerable to apps crashing on it - it
may also exit with sigpipe. this needs fixing.
3. if the apps load using relative paths - this will break as it doesnt
account for the CWD of the client currently. will be fixed.
4. no way to change cache config runtime (yet)
5. no way to get internal cache state (yet).
6. if cache server exist - it wont clean up the shmem file nodes in /dev/shm
- it will clean on restart (remove the old junk). this needs fixing.
if you fine other issues - let me know.
things for the future:
1. now its a separate server.. the server could do async http etc. loads too
2. as a server it could monitor history of usage of files and images and
auto-pre-load files it knows historically are loaded then whose data is
immediately accessed.
3. the same infra could be used to share font loads (freetype and/or
fontconfig data).
4. ultimately being able to share rendered font glyphs will help a lot too.
5. it could, on its own, monitor "free memory" and when free memory runs
load, reduce cache size dynamically. (improving low memory situations).
6. it should get a gui to query cache state/contents and display visually.
this would be awesome to have a list of thumbnails that show whats in the
cache, how many referencesa they have, last active timestamps etc.
blah blah.
please let me know if the build is broken asap though as i will vanish
offline for a bit in about 24hrs...

enabled. the blending is not working/complete. the neon for fills and copies
isnt actually faster though currently :(
2. scalecache infra - disabled for now. working on it.

* evas/src/lib/engines/common/evas_font.h,
* evas/src/lib/engines/common/evas_font_draw.c,
* evas/src/lib/engines/common/evas_font_load.c,
* evas/src/lib/engines/common/evas_font_query.c: Add cache for font kerning.
This patch give something around 2% for all tests around text in expedite,
except for Textblock Intl where it give a 3 times boost.
Regarding text rendering speed, something is strange when used by evas_pipe.
All tests using Styles are around 40% faster without evas_pipe. 30% faster
for Text Change. But Text Basic 7% slower. So it should be possible to have
faster rendering when using evas_pipe for font rendering.

1 - use inlist as regular list uses non-thread safe mempool;
2 - lock around image loading, so if main thread requests pixels right
before worker thread is loading them, you don't get ie->info.module
to NULL while it would be used (triggered from engines/common).
Maybe this should be handled by a global mutex elsewhere instead of
per-image mutex, but it has more granularity now.
3 - emit "preloaded" callback if it was canceled to be loaded from main
thread.
Please someone review these changes.

tyo fix up some of these breaks first and there isn't a lot of time devoted
to this. so revert this. it's in svn history so we can dig it out any time we
like.

1. nearest scaling is now broken - it's always linear interpolation. this
will lead to slowdowns. i need to fix this - a must.
2. i think it's time i put in a transformed image cache that can cache an
image object at a transform (and share it) automatically.
3. transforms in non-software-engines will not work - broken. need to at
least do xrender and gl engines.
any volunteers to help?

- some enignes break as they dont have the stubbed out functions, and
xrender/gl engines dont even implement the drawing and need to (but are
stubbed out).

Image_Entry flag structure. This fix a bug with 16 bpp software engine.
* Change image loader module API to take any Image_Entry. Same goes
for evas_common_image_premul and evas_common_image_set_alpha_sparse.
* Use new eet API: eet_data_image_read_to_surface.

This patch fixes the problem with bitfield of signed types (ie: char),
where the bit would be used for the signal, so 1 is considered -0 and
thus 0.
Move all the single bit fields to Evas_Bool, making it clear and also
avoiding these problems since Evas_Bool is unsigned char.

tuned for best performance on my core2 duo desktop - for now. will check
more. also make the yuv colorspace code be a bit more robust and fix leak in
gl engine with shaders.
SVN revision: 30192
in evas_gl_texture.c i have a frag shader, and it tries to use a set of 3
textures that act as the yuv planes, BUT the u and v textures (Utex and Vtex)
are simply getting values from the Ytex - regardless of what i try. grrr.
what's up with that?
SVN revision: 27495
sometimes slower)
2. --enable-pthreads will enable multi-threaded rendering (current support is
for up to 4 threads so if you have a new fanled quad core or dual cpu dual
core box or whatever you will in theory be able to max moe of its cpu grunt
with the software rendering engine. this can only be done because i added the
pipelines which means almsot entirely lock-free multithreading internally in
evas. the only locks are for fonts but with a little work i might be able to
remove some/most of those too)
for now pthreaded rendering likely will be linux only (it relies on sched.h
for setting scheduler params to force the slave threads to run on separate
cpu's as linux likes to keep them on the same cpu otherwise and thus we get
no speedups at all - only slowdowns).
aso note that it is a bit of a mixed bag. complex ops (like smooth scaling
with alpha blending) get speedups, but simple ops (like blits/fills) slow down.
this all neds examination and tweaking still - but it's a start.

renderer gets threaded). if i thread at the simplest levels (low down in for
example the image scaler code - one of the most expensvie gfx routnes) on an
actual dual core system - performance drops by 40%. this just doesn't work
well at that level. thread creates and joins per render op are just a bad
thing (tm) :) so this really needs to go in much higher up and that presents
problems. :( i will need to clearly define entry and exit points to and from
threaded space (and thus all the locks) - remove all nested calls (where
internal code goes thru the same entry/exit points traditionally so it
deadlocks itself).. anyway - this here has all that code stripepd out i
played with - it is just the autofoo and build stuff so we can turn on/off
thread support at will in the build.
