- Send paths to all connected clients
- Send paths upon connection from a new client
- Client side:
- Fast find opened images
- Fast find loaded images
- Optimize load by skipping socket wait
Also, remap indexes when needed (file size changed)
When index file grows, the clients are not notified, so they
must constantly check that their mapping matches the current array
size.
- Move required struct definitions to common evas_cs2.h
- Open/close shm and map arrays to memory
Pretty stupid for now as it will close & reopen the shm files
even when unchanged.
- Check shm size and array header consistency
- Implement message send
- Send messages from server when calling repack()
Only import the C file for now.
Implement the following features:
- Shared Arrays
Store arrays of elements of fixed size in shm.
- Shared Mempool
Store random sized buffers in shm.
These buffers are indexed in a Shared Array and are
referred to using their index only.
- Shared Strings
Store strings in a shm in a way similar to Eina_Stringshare
(except strings are referred to using an int index).
- Include evas_cserve2_index.c to the compilation.
- Declare shared index functions in header file.
- Call init() and shutdown() on the shared index subsystem.
- Add find and foreach functions
- cserve2_shm_segment_request()
Creates a new shm segment (Shm_Handle) from an existing file,
without changing the current mmap.
- cserve2_shm_resize()
Grows the file and remaps in memory (new virtual address).
- cserve2_shm_id_get()
Returns the shm creation ID.
In its current model, cserve2 will reopen, reload and scale an
image whenever a new scaled version is requested by the client.
Instead, we can load the original image when too many scaled
versions are requested, and place the original in the LRU.
Remove Image_Load_Opts and use Evas_Image_Load_Opts for cs2 master to
slave communication.
2 things to note:
- The struct size is bigger (but at the same time we removed a memcpy)
- The scale_load field is not passed to the slave
When opening an image, OPEN and SETOPTS were always sent
consecutively. Merging these two messages may improve the
performance a bit (not measured), but also simplify the
whole thing.
Note: cserve2 debug tools have not been fixed yet.
Some hashtable lookups failed because the keys were added
either with eina_stringshare_add() or e_s_add_lenth() but
looked for with e_s_add_length() only.

Evas_Common.h should be used for the public header, and rather rename
evas_common.h internal header to another name.
Sa:
Evas_Common_Header.h -> Evas_Common.h
evas_common.h -> evas_common_private.h
Shouldn't have both Evas_Common.h and evas_common.h because of case
insensitive filesystems.
I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
