Some names have not been changed, hopefully making a distinction
between legacy APIs and internal code (elm_layout_blah) and valid EO
usages.
This means many internal functions are still elm_layout_ as their
sole purpose is to support the legacy API.

1. The word "class" is a pain point with many languages where
it's a keyword. Type is a little better. Also, the property
was already named "device_type" and not "device_class".
2. Remove Efl.Input.Device.Sub_Class
It's not used inside EFL upstream codebase, and unlikely to
be used anywhere else (even in Tizen).
Hopefully no one used the Efl_ enum types. So far only the Evas_
types should be in used.
Ref T5540
Those are now merged with Efl.Object parent, name and comment.
The reasoning is that only seats can be parent devices; And name
and description are not only name clashes but also not extremely
useful anyway.

This implements an entirely new API model for Evas Map by relying
on high-level transformations on the object rather than an external
Evas_Map structure that needs to be constantly updated manually.
The implementation relies on Evas_Map.
To rotate an object all you need to do now is
efl_gfx_map_rotate(obj, 45.0, NULL, 0.5, 0.5);
Or with a C++ syntax:
obj.rotate(45.0, NULL, 0.5, 0.5);
Or even simply (with default arguments):
obj.rotate(45.0);
The map transformation functions are:
- rotate
- rotate_3d
- rotate_quat
- zoom
- translate (new!)
- perspective_3d
- lightning_3d
@feature
In the map examples, the map image UV size was based on the image
source geometry, rather than the image geometry itself.
In the example, this affects how the glass is mirrored. Before this
patch, the reflection is a single line stretched. EFL 1.18 and 1.19
seem to have the same issue, while 1.17 simply fails to show any
reflection. 1.16 fails miserably and the entire window is black.
If the original code was correct, then I believe that map and/or
proxy rendering have been modified in a way that affects the meaning
of those image UV parameters. But this seems like the regression (if
it is one) is in fact quite old.

This is the local socket for windows, analogous to AF_UNIX.
`Efl_Net_Socket_Windows` is the base class doing `ReadFile()` and
`WriteFile()` using overlapped I/O, as well as the close procedure
(`FlushFileBuffers()`, `DisconnectNamedPipe()` and
`CloseHandle()`). These are done on top of an existing HANDLE that is
set by `Efl_Net_Dialer_Windows` (from `CreateFile()`) or
`Efl_Net_Server_Windows` (from `CreateNamedPipe()`).
The overlapped I/O will return immediately, either with operation
completed or `ERROR_IO_PENDING`, which means the kernel will execute
that asynchronously and will later `SetEvent(overlapped.hEvent)` which
is an event we wait on our main loop. That `overlapped` handle must
exist during the call lifetime, thus cannot be bound to `pd`, as we
may call `CancelIo()` but there is no guarantee the memory won't be
touched, in that case we keep the overlapped around, but without an
associated object.
Windows provides no notification "can read without blocking" or
non-blocking calls that returns partial data. The way to go is to use
these overlapped I/O, with an initial `ReadFile()` to an internal
buffer, once that operation finishes, we callback the user to says
there is something to read (`efl_io_reader_can_read_set()`) and wait
until `efl_io_reader_read()` is called to consume the available data,
then `ReadFile()` is called again to read more data to the same
internal buffer.
Likewise, there is no "can write without blocking" or non-blocking
calls that sends only partial data. The way to go is to get user bytes
in `efl_io_writer_write()` and copy them in an internal buffer, then
call `WriteFile()` on that and inform the user nothing else can be
written until that operation completes
(`efl_io_writer_can_write_set()`).
This is cumbersome since we say we "sent" stuff when we actually
didn't, it's still in our internal buffer (`pd->send.bytes`), but
nonetheless the kernel and the other peer may be adding even more
buffers, in this case we need to do a best effort to get it
delivery. A particular case is troublesome: `write() -> close()`, this
may result in `WriteFile()` pending, in this case we wait using
`GetOverlappedResult()`, *this is nasty and may block*, but it's the
only way I see to cope with such common use case.
Other operations, like ongoing `ReadFile()` or `ConnectNamedPipe()`
will be canceled using `CancelIo()`.
Q: Why no I/O Completion Port (IOCP) was used? Why no
CreateThreadpoolIo()? These perform much better!
A: These will call back from secondary threads, but in EFL we must
report back to the user in order to process incoming data or get
more data to send. That is, we serialize everything to the main
thread, making it impossible to use the benefits of IOCP and
similar such as CreateThreadpoolIo(). Since we'd need to wakeup the
main thread anyways, using `OVERLAPPED.hEvent` with
`ecore_main_win32_handler_add()` does the job as we expect.
Thanks to Vincent Torri (vtorri) for his help getting this code done
with an example on how to do the NamedPipe handling on Windows.
While in UNIX we use 'select()/poll()' to query for read fds and this
will eventually callback with "can_read" event, use the loop to match
other implementations where can_read keeps true if not all data was
read.

Use seat names as prefix, not as suffix, following
a top-down approach and avoiding issues
with applications that may be receiving
doubled signals (legacy + suffixed).
So instead of "mouse,in,seat1" signal will be
"seat,seat1,mouse,in".
Working directly with Eina_Slice is easier than a pointer to it,
requires no validation of the pointers and is cheap since it's just
putting together size_t + void*.
However we can't hint the user of 'const(Eina.Slice)' properties as
Eolian is incorrectly generating getters as:
const Eina_Slice class_property_get(...)
which is makes compilers complain about ignored qualifiers:
../src/lib/ecore/efl_io_copier.eo.h:329:7: warning: 'const' type qualifier on return type has no effect [-Wignored-qualifiers]
Leave some TODO so @q66 can fix those.
Previously we couldn't return a slice, instead required the user to
pass a slice and we'd fill it since Eolian couldn't generate fallbacks
for structures.
Since @q66 fixed eolian, we can now return the structure itself as
initially wanted, ditching some TODO from the code.
Since seat names defined on evas will depend on evas backends,
maybe udev rules, etc, we aren't able to demonstrate it
without manually setting another name for such seats
with efl_input_devices_name_set(). Otherwise
we wouldn't have guarantees it would match
names on EDC.
If not provided, FOCUS_OBJECT action will keep acting
over default seat.
Also include a usage on edje-multiseat test
(actually no example was exercising this action).
This is a string parser, serializer and asynchronous resolver.
It's purpose is to convert to and from the strings we use in our
dialers and servers, such as "127.0.0.1:1234" or "[::1]:1234",
properties allow to check the family, port, address bytes (slice) and
even get a struct sockaddr pointer to use with bind()/connect() in
outside code.
It will also offer some utilities present in netinet/in.h in an easy
to use way, after all IN6_IS_ADDR_LOOPBACK() works one way, while
there is no IN_LOOPBACK and comparing with INADDR_LOOPBACK will lead
to errors since it's in network order.
Last but not least, it will do asynchronous resolve of host and port
names using an internal thread and getaddrinfo(). The results are
delivered using a Future with an array of objects.
add a new -t/--type=tcp+ssl, there you can send "Upgrade: SSL\n" to
request the server to start the handshake.
This can be paired with the ecore_con_client_example, there you can
type:
Upgrade: SSL\n
STARTTLS\n
The second is a dialer local command to upgrade it to SSL, matching
what the server expects.
The example now offers --type=tcp+ssl, in this case it won't send a
"hello!" message to avoid messing with the handshake. Once the client
(dialer) receives the user command STARTTLS
(--starttls-local-command), then it will upgrade the connection.
Usually in real life you need to send some command to server, such as
upgrade, STARTTLS and then upgrade... unless you connect to a SSL-only
server (ie: ecore_con_server_example --type=ssl).
allow to not verify server certificate or hostname, so we can test
with local, self-signed certificates.
Also print errors, so we can say that the server handshake failed.
Instead of a single SSL connection, allow for local, tcp and udp,
optional flush and delete-after-write (--single-message) and echo
mode.

The low level I/O primitives are powerful but adds some complexity to
use, for bi-directional streaming communication one ends creating two
Efl.Io.Queue and two Efl.Io.Copier to pipe data to socket when it can
operate.
Then encapsulate the socket using the new Efl.Io.Buffered_Stream, this
will allow the socket, be a dialer or a server client, to be operated
as a single handle that internally carries about the buffering for
you.
As one can see in the examples, compared to their "manual"
alternatives they are very easy to use, ressembling
Ecore_Con_Server/Ecore_Con_Client, but also offers line-based
delimiters and the possibility to let the socket to handle queueing
for you in case you received partial messages (just do not
read/clear/discard the received data).
Since all other efl.io objects are low-level, the recommended approach
is to use an efl.io.copier. However when dealing with in-memory,
bi-directional comms like talking to a socket, we always end with 2
queues, 2 copiers and the annoying setup that is being replicated in
ecore_ipc, efl_debug and so on.
This class is the base to make it simpler. Other classes such as
Efl.Net.Socket.Simple, Efl.Net.Dialer.Simple and Efl.Net.Server.Simple
will use it to provide simpler code to users.
I guess we can call EFL+EO Java now?
If the server is gone, immediately delete it, this exercises deleting
the server from inside its event.
Then, if the server was already deleted, do not do it again.
Also remove the shadow variable, keep only the global scope.
ecore_file_download() will refuse to download if file already exists,
then we must unlink DST_MIME as done with DST before we try to
download, otherwise it won't work on the second time.
In commit 5929f0311d this was removed. While
the commits intend was to remove the cxx variant of this example only.
Bring this back so examples are building again.

These are objects to allow control of networking devices
(efl_net_control) as well as an application to request for
connectivity (efl_net_session).
They are loosely based on ConnMan.org, which we already use in
Enlightenment Window Manager via DBus access with Eldbus. However they
do not map 1:1 as the goal was to expose a viable subset of controls
but in a simple and general way, thus nome strings were converted to
enums, some arrays of strings were converted to bitwise flags, some
names were made more general, such as "service" was turned into
"access point" so it doesn't generate confusion with other "network
services" (ie: http server), or "favorite" that was renamed to
"remembered". Some behavior are slightly different (yet able to be
implemented on top), such as "Service.MoveBefore" and "MoveAfter" were
converted to a numeric "priority", calculated from service's list
index, changing the priority will reoder the list and thus generate
the MoveBefore and MoveAfter DBus commands.
ConnMan was chosen not only because we already use it, but because its
DBus API is sane and simple, with the server doing almost all that we
need. This is visible in the efl_net_session, which is completely done
in the server and do not require any extra work on our side -- aside
from talking DBus and converting to Eo, which is a major work :-D
NOTE: ConnMan doesn't use FreeDesktop.Org DBus interfaces such as
Properties and ObjectManager, thus we cannot use
eldbus_model_object.
There are two examples added:
- efl_net_session_example: monitors the connection available for an
application and try to connect. You need a connman compiled with
session_policy_local and a configuration file explained in
https://github.com/aldebaran/connman/blob/master/doc/session-policy-format.txt
to get a connection if nothing is connected. Otherwise it will just
monitor the connectivity state.
- efl_net_control_example: monitors, plays the agent and configure
the network details. It can enable/disable technologies, connect to
access points (services) and configure them. It's quite extensive
as allows testing all of ConnMan's DBus API except P2P (Peers).

it was using old API, updated, but still doesn't work as expected,
lots of warnings from children being left alive, all proxies are
reporting no properties...
when model dies, all children proxies should die as well, otherwise we
get on console:
```
CRI:eldbus lib/eldbus/eldbus_core.c:215 eldbus_shutdown() Alive TYPE_SYSTEM connection

...
```
Also, all proxies are reporting no properties "(no properties yet)",
likely they are missing to fetch such... even if "--wait" to let it
run, no asynchronous properties are delivered, at least not triggering
EFL_MODEL_EVENT_PROPERTIES_CHANGED.
in the previous commit we're manually upgrading an existing TCP socket
to SSL. It is desired since some protocols need to negotiate, like
STARTTLS and the likes
Now we offer 2 classes that does autostart SSL once the socket is
ready.
This introduces AF_UNIX server and dialer, these are not available on
Windows as in that platform we'll create a custom class for native
'local' communication.
In the future we can add a wrapper class Efl.Net.Local that will use
the class for each platform, but won't expose its details.
For instance, if we ever expose 'credentials' (which I didn't because
they are not portable), then it doesn't make sense to try to match
that on Windows. The 'Efl.Net.Local' would just stick to the basics:
Reader, Writer and Closer APIs.
now that we have a 'bind', let's use the given address as bind and
dial to `0.0.0.0` or `::`. This allows the dialer to receive data at
the given address and make the example useful.
This was a huge work, but now UDP is usable as seen in the examples.
Instead of relying on 'connect()', just do 'sendto()' and 'recvfrom()'
as they are universal. Multicast address can only be connected in
IPv4, IPv6 wasn't working and I'm not sure the IPv4 is portable to
other platforms.
Dialer will auto-join multicast groups is the dialed address is
one. Multicast properties such as time to live (hops) and loopback can
be configured. When joining multicast groups, the local
address/interface can be configured by 'IP@IFACE' format, with
'@IFACE' being optional.
Dialers will now auto-bind, so it can receive data as dialers are
expected to be bi-directional. One can manually specify the binding
address if there is such need.
Since datagrams must be read in their full size, otherwise the
remaining bits are dropped, expose next_datagram_size_query() in both
Efl.Net.Socket.Udp and Efl.Net.Server.Udp.Client.
To finalize UDP for real we need to introduce an 'Efl_Net_Ip_Address'
structure to serve as both IPv4 and IPv6 and expose 'sendto()' and
'recvfrom()'. These will come later as this commit is already too big.
Instead of using 'bool', which requires a parameter to be useful, make
them toggle of the default value.
Adapt names to make more sense in that context.
This is handful to error the copier with ETIMEDOUT if there are no
reads or writes in the given amount of time.
Since copiers are usable to download data or handle network clients,
it's easy to set a timeout and disconnect, let's say UDP clients that
are gone.
This is the initial UDP server that works similarly to the TCP one,
however under the hood it's widely different since the socket is
reused for all "clients", thus needs a new Efl.Net.Server.Udp.Client
(Efl.Net.Socket) as Efl.Net.Socket.Udp exposes the fd and options such
as 'cork', which would interfere in other clients.
The main socket will read the packets and find an existing client to
feed it. If no client exists, then it will create one if not overr
limit. Since there is no kernel-queuing as done by listen()/accept(),
the 'no reject' case will just accept the client anyway.
Next commits will improve UDP server handling with some advanced
features:
- join multicast groups
- bind to a specific interface (SO_BINDTODEVICE)
- block packets going out of local network (SO_DONTROUTE)
- specify priorities (SO_PRIORITY)
instead of blindly reading and writing, which can lead to hangs due no
server, let's use can_read and can_write to do the operations, this
won't let us believe we can read when we can't.
it's also the recommended approach, so let's show that in the examples
so users don't copy&paste incorrect stuff :-)
Sometimes we want to handle both IPv4 and IPv6 in the same socket,
instead of spawning 2 servers, one for each protocol. That is achieved
by means of disabling IPV6_V6ONLY socket option, present in most
recent platforms.
Like existing ecore_con code, this does not use SOCKSv5 UDP
proxy. It's kinda cumbersome to add since requires a keep alive TCP
connection to the server, a second UDP channel and framing around the
original UDP frame.
Added UDP_CORK (if present) to match TCP_UDP present in TCP sockets,
this allows one to execute multiple write() calls that will result in
a single datagram, generated when CORK becomes FALSE again.
The efl_io_copier_example.c now accepts this as output. There is no
input UDP as there is no way to notify the server of a connection
(since such thing doesn't exit), usually servers react after a
datagram is received, replying to the source.
Similarly to group_color_set, group_clip_[un]set should not
exist and should be a result of efl_super and inheritance.
This patch also removes clip_unset from the EO API and keeps
only clip_set(NULL). The reason is that it will avoid bad overrides
of clip_unset() vs. clip_unset(NULL). This also simplifies the code
a bit. Ideally we should be able to reintroduce clip_unset in EO
if we can have a "@final" tag (like java's final keyword), to
prevent overrides.
Remove codegen_example_generated.h from codegen_example_SOURCES
and let it only on nodist_codegen_example_SOURCES and

Even if WebSocket is a message-based protocol (like "packets" from
UDP), you can use efl_net_dialer_websocket_streaming_mode_set() to
tell it to handle text or binary messages as a stream. Then all the
Efl.Io.Reader and Efl.Io.Writer APIs work as expected, see
efl_io_copier_example.c updates.
This adds support for distance, pressure, tilt and twist.
Not entirely sure if normalized & raw (x,y) should be exposed
in the eo interface. Also not sure what to do with tilt_x/y
(as used by libinput) or touch/tool width "major/minor" vs.
radius x/y.
Add debug logs in the example, including the distance.
I can't test most of these values due to a lack of compatible
hardware, but the most basic features seem to work :)
The use of low-level interfaces such as Efl.Io.Reader and
Efl.Io.Writer are not that user-friendly as they can handle partial
data.
Classes such as Efl.Io.Copier makes them easy to use, but they need a
reader (source) or writer (destination) and in our examples we used
fixed buffers or some existing streams (stdin/stdout/stderr,
networking...).
However, if interactively we need to produce some data to be sent,
such as implementing some networking protocols, we'd have to write our
own Efl.Io.Reader and Efl.Io.Writer classes to handle the buffering.
Not anymore! With Efl.Io.Queue you can write stuff to it and it will
buffer to memory. Once stuff is read, it will automatically remove
those bytes from buffer.
so efreet mime was loading a bunch of mime type info files, parsing
them on startup and allocating memory to store all this mime info -
globs, mimetype strings and more. all a big waste of memory as its
allocated on the heap per process where its the SAME data files loaded
every time.
so make an efreet mime cache file and a tool to create it from mime
files. mmap this file with all the hashes/strings in it so all that
data is mmaped once in memory and shared between all processes and it
is only paged in on demand - as actually read/needed so if your
process doesnt need to know about mime stuff.. it wont touch it anyway.
this saves about 240-300k or so of memory in my tests. this has not
covered the mime MAGIC files which still consume memory and are on the
heap. this is more complex so it will take more time to come up with a
nice file format for the data that is nicely mmaped etc.

This class implements the Efl.Net.Dialer interface using libcurl to
perform HTTP requests. That means it's an Efl.Net.Dialer,
Efl.Net.Socket, Efl.Io.Reader, Efl.Io.Writer and Efl.Io.Closer, thus
being usable with Efl.Io.Copier as demonstrated in the
efl_io_copier_example.c
Efl.Net.Server defines how to accept new connections, doing the
bind(), listen() and accept() for protocols such as TCP.
Efl.Net.Dialer defines to to reach a server.
Both are based on Efl.Net.Socket as communication interface that is
based on Efl.Io.Reader, Efl.Io.Writer and Efl.Io.Closer, thus being
usable with code such as Efl.Io.Copier.
The Server will emit an event "client,add" with the established
Socket, which is a child and can be closed by both the server or the
user.
The Dialer extends the Socket and allows for creating one given an
address, that will be resolved and connected.
TCP is the initial implementation so we an validate the
interfaces. UDP, Unix-Local and SSL will come later as derivate
classes.
The examples are documented and should cover the basic principles:
- efl_io_copier_example can accept "tcp://IP:PORT" and will work as a
"netcat", can send data from socket, file or stdin to a socket,
file, stdout or stderr.
- efl_net_server_example listens for connections and can either reply
"Hello World!" and take some data or work as an echo-server,
looping back all received data to the user.
More complex interactions that require a "chat" between client and
server will be covered with new classes later, such as a queue that
empties itself once data is read.
These interfaces allows generic operations on objects that can store
or provide data, such as a file or a buffer.
With well defined interfaces and events we can create code such as
Efl.Io.Copier, that will link a source with a destination and
progressively copy data as they appear.
Only perform the single value/return type substitution on properties if the
void return type is implicit (i.e. NULL return from function_return_type_get),
following the eolian-C implementation as we use the generated headers.
Also update example after Eo-Efl changes.
At some point we lost the \ after track_example_01 and in combination with the
commented out line right afterwards we lost all examples coming after this line.
This just surfaced with JPs latest commit when I did a distcheck build but was
there for a longer time. We now make sure all disabled examples are moved out of
the multi-line list.

The edje text example covers the translation functionality which need the mo
and po files during edje_cc compilation. Further more the folder need to be
writable to create the new mo/po files.
We need to ensure that this is the case during a distcheck which is read only
on the source tree.
This is to show that proxies can proxy more than just other
images, and also this was done to test D4159 (alternatively
changed into the previous commit).
In commit 3340745c65 the callback array got
removed letting all callback functions around as unused. Somehow the setup
of all these callbacks have gone missing over various refactors.
Missing parenthesis have been leading to an out of bound access here.

evas-images5.c:19:0: warning: "EFL_BETA_API_SUPPORT" redefined
#define EFL_BETA_API_SUPPORT
^
In file included from evas-images5.c:14:0:
../../../config.h:360:0: note: this is the location of the previous definition
#define EFL_BETA_API_SUPPORT 1
We should only define it when we are not using config.h
My recent removal of the EFL_EO_API_SUPPORT define brought some trouble to the
evas 3d examples. The problem was that there was no uniform usage of including
config.h and thus it worked fine in some constellations abut not in others. This
patch should fix the known problems and brings back EFL_EO_API_SUPPORT until we
are removing it from the whole code base.
Reported by Simotek when testing the latest snapshot:
Were getting closer, "/usr/bin/mkdir -p /usr/share/elua/examples" should
be "/usr/bin/mkdir -p
/home/abuild/rpmbuild/BUILDROOT/efl-1.17.99.48545-1.x86_64/usr/share/elua/examples"
We are using cos() and sin() in the efl_thread examples here but never linked
to the math lib. Ubuntu 14.04 on Travis CI errored out with this:
/usr/bin/ld: efl_thread_1.o: undefined reference to symbol 'cos@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line
This allows apps to set the objects min size with hint_min,
while letting the rest of EFL define the minimum size with
rstricted_min.
I don't like the property names much...
The ecore_audio examples have been disabled and now do not compile right now.
But as they are disabled they never land in the tarball and thus we error out
with files not aviavle for install. Found by the OpenSUSE build service. Thanks
Simotek for reporting.
