cserve2 does not support animated Gifs, as the animated icon
logic doesn't match cserve2 logic.
Also, there is probably no need to cache these into shared
buffers anyways :)
Solution: fallback to normal cache (and delete current entry in
the client)
Let's reuse the logic from scalecache and call cserve2
functions when the scalecache should be used.
So, now, cserve2 server will not scale any image... This is
too computationally intensive for the server's main thread.
This is not optimal but makes a hell of a lot more sense for
the moment. (since cserve2 manages the SHM segments)
High-level problem:
cserve2 does not support load_opts properly when opening an image.
As a result, when (pre)loading a JPEG file with specific load
options (eg. w, h, region and orientation), the image buffer might
have the wrong dimensions.
So, we need to use load_opts when computing file hash key.
And, pass these load options to the loader slave,
and use them while OPENING the image. This will set
properly the geometry.
Fixes test "Preload and Prescale" in elementary_test.
Pass around "animated" flag for images that can be animated.
Fallback to local cache if the image is animated.
Implementing support for animated images in cserve2 does
not seem to make a lot of sense considering each frame must
be requested independently in real time,... and to be honest
there doesn't seem to be any valid use case anyway :)
cserve2 can't handle virtual files (mmap-only), by design.
Proper support can be added later on, but for now we might want
to just fallback to the normal cache functions.
Fixes photocam test
Images and Files can be discovered by the client scanner before they
are valid (aka. loaded or opened). We want clients to ignore all
shared objects that are not ready yet, as they are in an undefined
state (values and memory might be invalid).
Shared string indexes are not repacked, since they live in a
memory pool (where the indexes can be reused).
So, the index in the table is equal to their ID. Add initial
test to check if the item at index n has the ID n.
Use tags such as INDX, FONT, IMAG, FILE.
These can help debugging and for robustness, as they will
be visible in the memory dump.
Update generation_id after repack as well
Also, print shared arrays usage as it is sent as first message
upon connection to the server.
Add fonts to LRU and flush LRU as needed.
Seems to work okay. Could probably be finetuned a bit.
- Create one Glyph_Data array per Font_Entry
- Copy Font_Source descriptors in shared array
- Copy font entries in shared index
- Send font index path over socket
- Merge Font_Source and Font_Data in shared memory
- Send font index path on client connect
- Repack font index after free
- Pass font shm name to clients
Read Image descriptors from the shared arrays
But, accessing the shared index can be a bit expensive, so
try to read from the socket before scanning the index,
without blocking.
- 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()
this fixes https://phab.enlightenment.org/T182 as it is an issue with a
surface alloc overwriting an already allocated surface entirely inside
the general software image infra.
time 0
for ECORE_EVENT_SYSTEM_TIMEDATE_CHANGED we use a timerfd on linux (and
also support talking to systemd) to detet time/date changes. the
timerfd was set up to go off at the absolute time of 0. since that is
almost always... in the past.. lets set a REAL time in the future.
(almost end of time)
We need a function in DnD for the overlapping feature to retrieve all
the objects at a specific position.
A private function exists in Evas (evas_event_objects_event_list) for
that purpose.
We need an access to this function for Elementary but we don't
want the is_frozen flag to be checked.
Summary:
Some characters have different two value on glyph's width and horizontal advance width.
If the glyph's width is smaller than advance width, format can be drawn weird.
Test Plan:
Set underline:on to the entry style and just insert the following characters.

From glibc mkstemp man page:
In glibc versions 2.06 and earlier, the file is created with
permissions 0666, that is, read and write for all users. This old
behavior may be a security risk, especially since other UNIX flavors
use 0600, and somebody might overlook this detail when porting
programs. POSIX.1-2008 adds a requirement that the file be created
with mode 0600.
More generally, the POSIX specification of mkstemp() does not say
anything about file modes, so the application should make sure its
file mode creation mask (see umask(2)) is set appropriately before
calling mkstemp() (and mkostemp()).
And:
http://cwe.mitre.org/data/definitions/377.html
By tranversing the whole of the map target's tree,
it decides to update the map surface to be redrawn if one of the objects is changed except the clipper itself.
now that it's runtime dlopen'ed etc. ecore-con "always" has url
support via curl so ecore-file needs to assume that this can always
work and this just use ecore-con-url anyway.
Is there a title for the commiter with the longest revert of a revert list?
I screwed this one up. Had other local changes that sneaked in.
Resetting and doing it right now.
This reverts commit ee155b771d.
You can bet on reverting makes people speed up the process in fixing it.
Revert the revert here now that Cedric fixed it in eina.
This reverts commit 875e7cf74d.
This is really useful to track down a leak of a memory piece allocated by an
eet_data function. If you know the size of the leaked structure (valgrind
give you the total allocated size and the number of structure in it, so you
need to divide before having the right number), you just need to do :
EINA_LOG_LEVELS=eet:3 my_app 2>&1 | grep the_size
And there will be very few line matching reducing what you should be looking at.
this makes curl support a pure runtime-only thing. libcurl is loaded by
eina_module (dlopen/dlsym) when curl is actually first needed (when a
url connection/object is created). this means that ecore-con has no
link or compile dependencies on curl, only runtime, AND this saves
memory (due to curl inits using apparently a chunk of private pages).
so this saves memory and moves the dependency to runtime (though still
consider libcurl a dependency of efl - but like a binary executed,
it's at runtime).
