now seriously...
Introducing Cache Serve 2.
This cache server will initially load images for clients connected to
it. It starts slave processes to load these images, and share the loaded
images through shm with the clients. All the connection done between
clients and the server goes through sockets.
The cserve2 build option is turned on by default, while the old cserve
was disabled, but in order to make clients use it, the environment
variable EVAS_CSERVE2 must be set, and a server must be running.
Clients will try to find the socket on a specified location using the
environment variable EVAS_CSERVE2_SOCKET. If it's not defined, then the
XDG_RUNTIME_DIR path should be used, and finally HOME, TMPDIR and /tmp.

Subject: [E-devel] [Patch] [Evas] Patch to provide information of
touched points
Hello,
I made a new patch to get information of current touched point instead
of Touch Event.
I added touch_points (Eina_List) to the Evas structure and it maintains touched points on the evas.
New touched point is added to the touch_points when we get Mouse_Down and Multi_Down,
touched point is updated when we get Mouse_Move and Mult_Move,
and touched point is removed when we get Mouse_Up and Multi_Up.
The each touch point has coordinate, id and state information as follows:
id - identifier. 0 for Mouse Event and device id for Multi Event. coordinate - (x, y) coordinate of point.
state - state of point. type is Evas_Touch_Point_State enum.
(EVAS_TOUCH_POINT_DOWN, EVAS_TOUCH_POINT_UP, EVAS_TOUCH_POINT_MOVE,
EVAS_TOUCH_POINT_STILL, EVAS_TOUCH_POINT_CANCEL)
There are 4 new APIs to get touch point's information as follows:
unsigned int evas_touch_point_list_count(Evas *e);
void evas_touch_point_list_nth_xy_get(Evas *e, unsigned int n, Evas_Coord *x, Evas_Coord *y);
int evas_touch_point_list_nth_id_get(Evas *e, unsigned int n);
Evas_Touch_Point_State evas_touch_point_list_nth_state_get(Evas *e, unsigned int n);
I added APIs to get each information instead of exposing whole
structure to make it easy to expand in the future as you mentioned in
the below e-mail :)

Subject: [E-devel] [Patch] Evas touch event patch.
Nice to meet you.
I'm Eunmi Lee, developing mobile web browser and working on WebKit EFL port.
I need new type of event for touch, so I've made patch to add
EVAS_CALLBACK_TOUCH event to the evas.
I will explain history of this patch.
Currently, many web applications and sites use TouchEvent and they can
do everything(scrolling, zooming and so on) like native application
using TouchEvent.
So, I'm also want to provide TouchEvent for web in the WebKit EFL port,
but I got a problem during making TouchEvent because EFL's touch
event's structure (Mouse, Multi Event) is different from Web
TouchEvent's one.
Let me explain about Web TouchEvent firstly.
Web TouchEvent is consist of type and touch points list simply.
There are 3 kinds of type.
TouchStart: Happens every time a finger is placed on the screen.
TouchEnd: Happens every time a finger is removed from the screen.
TouchMove: Happens as a finger already placed on the screen is moved
across the screen.
for example, we can make (1 finger starts to touch), (2 fingers are
moving), (1 finger is released duirng 3 fingers are moving) and so on.
You can see the detailed information in the following url:
http://www.sitepen.com/blog/2008/07/10/touching-and-gesturing-on-the-iphone
However, EFL's touch event is consist of six kinds of type :
MOUSE_DOWN, MOUSE_UP, MOUSE_MOVE, MULTI_DOWN, MULTI_UP, MULTI_MOVE.
So, I have to make a converter to make web touch event from EFL's
touch event.
You can reference attatched image file : evas_touch_event.png.
To tell the truth, converting code is not a big one.
But, I want to reduce this additional job and make code simple.
In the WebKit QT port, they don't have to make converting code for
TouchEvent,
because they have QTouchEvent, it has type and touchPoints list and
they can be mapped to Web TouchEvent one by one.
I think iPhone and Android also have such kind of event.
That's all why I want to add new touch event type to the evas.
about my patch:
- EVAS_CALLBACK_TOUCH event is added
- touch_points Eina_List is added to the Evas structure to maintain
current touch lists.
- process MOUSE/MULTI UP, DOWN, MOVE to make TOUCH event.
It is my first time to modify eves codes and actually I don't know too
much about evas.
So, I will be grateful if you send any feedback and comments.

More work, proudly supported by Samsung. Filters!
So now you can apply a whole host of cheesy visual effects to objects at
runtime. This is the first commit, there are a couple of more to come as I
tweak the filters, and fix blur with GL[1].
Please direct bugs to me nash@nash.id.au.
[1] You'd think shaders would be good at this.. but no, generic blur and GL
are like trying to get an apple product to work with Linux.

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...

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.
SVN revision: 37453
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?

Table code is still *incomplete*, it just do homogeneous layouts as
I'm still trying to figure out how to make it great.
I'm not expecting to make layout configurable, as we did for box, but
if you think it's required we can do that later.
Now that the public API of both BOX and TABLE are in, we can add these
as parts of Edje.
SVN revision: 37359
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.

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.

textblock2 (the old textblock code is still there in textblock_old and the
api is still there until we swtich over).
...
important right nwo is COMMENTs on the api. do u like it. i am tryng to
keepit simple. right nwo i am writing JUSt enought to implement the markup
set api and styles - not a lot for editing and detailed queries yet. i will
work on that once the basic markup parse, style stuff and layout is done.
SVN revision: 16017
a dozen key grabs at any time may impact key event handling a little...
oh yeah.. added to the api .. now theres a modifier mask and a not_mask. the
not mas means "grab the key only if NONE of these modifiers are active and
only if one or more of the mask modifiers are active). using this you can
easily select allmodifiers, none, or a certain set of modifiers. if you need
more than that put in multiple grabs then :) to just have that exact set of
modifiers grabbed have not_mask be the inverse of mask. :)
