Subject: [E-devel] [evas] Add RGBA -> grayscale 64 entries palette conversion
This is needed for E-Ink devices outta there. Names of new files,
configure.ac variables and macros are awful, suggestions are welcome.

- Forgot to reset clip before drawing cleanup rect.
- Always draw a rect to reset the background, just
choose a correct color.
Note: This will slow down software_x11 engine, as this engine
always do memset, so it does it twice. Before only the alpha
case was impacted, now both case are. Need time to fix it. If
someone has, don't hesitate :-) You can use elementary windows
state test, to see if thing is going correctly or not.
For the record, SDL engine has a score around 500 under X11 on
my computer, where the X11 engine does only have a score around
450.

evas_common_font_utf8_get_prev currently works correctly only on an
ASCII symbols. For non-ASCII it just returns random garbage somehow
constructed from a string.
Attached patch makes it work according to the comment at the start.
SVN revision: 41292
Improvements: Now evas rendering loop is the one responsible to
initialize the surface to 0 correctly (taking into account surface
alpha and object opacity). This will reduce the number of memset
we do.
Note: Current software_x11 (xlib and xcb) are buggy. They are
copying too much data when the surface use a mask. That's why
two memset are left in their code. They could be removed, but
we should fix the surface we copy on change (look at mxob user
and evas_software_xlib_x_output_buffer_paste).

automake was "smart enough" to include in DIST_SUBDIRS even when 'if'
clause didn't add it to SUBDIRS, that was causing modules like XPM be
added twice, resulting maintainer-clean to double-clean the directory

second time.

the parent.
When we insert object inside a smart object, they could be attached to
another layer. As long as ref counting work, nothing wrong will happen.
But during destruction of an Evas, we were just looping over all layers,
destroying each of them, without checking for refcounting. This could
cause SEGV.
This patch introduce a third loop for wiping out all layers after
destroying all Evas_Object. So no more SEGV, and no performance
regression.
Note: Do not rely on evas_object_layer_get on smart object's child, it
could give you the wrong answer.

2. fixes to scalecache and cserver too. more toto's done and its now been

(cmd-line options avalable plus cmd-line tol to query settings change on the
fly and query statsitics and state)

- don't package directfb, it's for specific systems like embedded
where it is required to build manually, maybe define some tweaks.
- don't build with no-dither-mask as it will completely disable
dithering on 16 and 8bpps, that's wrong! This is supposed to be
enabled on embedded devices only, like maemo.
SVN revision: 40518
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...

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.
SVN revision: 38993
For some unknown reason evas was informing EVAS_CALLBACK_* even if the
original call did not changed the internal object state, that is, new
value is already equal to current value.
This is specially costly since Edje, Box, Table and possible other
layout engines will call evas_object_resize(), move(), show(), hide()
even if the state has not changed, assuming evas will ignore the call
(as it does). The real overhead might come if there are listeners
attached to these events, that in turn might do lots of other stuff,
leading to a torrent of useless calls.
I marked it for removal, please test it and uncomment '#define
CALLBACK_NOOPS' to get the old behavior back. It does seems to work
with e17 and edje_editor. If problems appear, let's try to fix the
real problem instead of getting this code back, it's a performance
penalty.

If one want to load image at a given height or width and the other

we should just remove entries pending preload from the cache being
shutdown, not all of them.
this is untested as it is hard to force this situation, but should be
more correct than the previous.
SVN revision: 38747
before, when no more images were to be preloaded asynchronously, the
thread exited, but were not collected. This leads to a huge leak if
the process is doing aggressive use of image preloading (ie: photo
wall).
collecting dead threads in a proper way (read: without race
conditions) is a bit harder than keeping just one thread alive,
forever. As we do that for evas_pipe (the renderer), let's do the same
with preload and save code.
SVN revision: 38746
users of buffer engine (ie: e_thumb_main.c) were broken since when
they resize the canvas they would implicitly call engine->setup()
again, which would destroy output and create it again. However the
cache could be destroyed and images using it would be bogus.
This does not happen if the process have other cache users, but
e_thumb is just one canvas live at time.
By reordering, we have the cache reference to go to 2 and then back to
1, not destroying it.

1. get rid of grammar mistake
2. refer to COPYING-PLAIn correctly as the filename
3. be more explicit on "shipping source" due to ambiguity (this makes it what

original COPYING from e. author and dates at the top remain the same.
SVN revision: 38569
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.

Wow, this was tricky to find since it is hard to trigger, thanks to
Canola complex edje files we could spot it!
In some cases we end with object being marked as dirty while
calculating its state (ie: edje), then we need to run smart calculate
again.
This has a drawback however: we cannot check for need_recalculate()
inside smart calculate anymore, we must assume it is only called if
the flag is set. To avoid that we could mark a shadow member and use
that or use a counter, that has the problem of using more data.
SVN revision: 38108
Eina hash api must get non NULL pointer allocated with
eina_hash_new(), but Evas hash started with NULL and would allocate
and destroy the hash as required by operations.
To do a proper wrapper we must ensure we don't call Eina hash API with
NULL, we must handle that outside Eina.
PLEASE do not remove this code again (it's the second time I add it),
this is the correct approach. Other than that is going after evas_hash
usage and converting directly to eina_hash.

Unset value is now 0x0 and this is handled as invalid, with an error message.

using that for unset values. With unset value at 0x0 it will not
happen and we'll know when we forgot to do so!.

giving an extra void *user_data to layout function is now easy to

args = PyTyple_New(1);
PyTuple_SET_ITEM(args, 0, Evas_object_from_instance(o));

Draw back: When we are destroying an Evas canvas, we loose all cached font

Box is a smart object to help with the common task of laying out lots
of objects. It's very flexibile and one can customize the layout
function on a per-object basis dynamically, just set a new layout
function (the most common are provided). By default layouts use size
hints from children to do their work, but one can also add new
properties, just subclass with evas_object_smart_smart_set() and then
define your own option_* callbacks.
This code was ported from Guarana (widgets/sequence_box.c) with
permission of ProFUSION embedded systems so it can be relicensed from
LGPL to Evas license.

almost "good". it gives a horizontal-blinds like look to dithering. it's

This class covers the most common cases, usually its sub-classes will
have to implement resize and override one or two methods at most,
making the smart object usage less error prone and easier.
Default behavior is:
- add: creates a hidden clipper with "infinite" size;
- del: delete all children objects;
- move: move all objects relative relatively;
- resize: not defined;
- show: if there are children objects, show clipper;
- hide: hides clipper;
- color_set: set the color of clipper;
- clip_set: set clipper of clipper;
- clip_unset: unset the clipper of clipper;
Documentation explains an easy way to inherit from this class and
still be able to use overridden methods.

Some people is using it for some time now without problems, so I'm
adding it to SVN to get some broader use. Remember to recompile ALL
libraries that depend on Evas as it will change the
EVAS_SMART_CLASS_VERSION and old classes will fail to load.
This will also change Edje so it will postpone _edje_recalc() to
render time, calculate() callback, however some methods will force
early recalculation.
