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.
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)
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.
The Efl.Net.Dialer.Websocket is just like other Efl.Net.Dialers: you
can dial, you can close, monitor connected/address resolved and so
on. And you can use WebSocket primitives and events such as
text_send(), binary_send(), ping() and close_request() (since
WebSockets use a close process where you should state a close
reason). See efl_net_dialer_websocket_example.c
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 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.
We hit another argument too long error with CLEANFILES. Moving the generated
files for js and lua into separated variables and cleaning them manually fixes
the issue.
This is again to avoid the "Argument list too long" error we are hitting more and
more now. Given we just merged elementary, emotion generic players, evas generic
loaders and elm_code it is not surprising we are hitting it again.
This time the number of files being hold in DISTFILES has just grown to big so a
make dist was no longer possible. If one looks at what the DISTFILES variable
from automake holds you can image it grows a lot with all the source files plus
generated files we have in tree now.
DISTFILES = $(DIST_COMMON) $(DIST_SOURCES) $(TEXINFOS) $(EXTRA_DIST)
To cut off a big chunk but still keep all the other automagic in place for
SOURCE files I went and renamed the EXTRA_DIST in src/ to EXTRA_DIST2 and handle
the files in a dist-hook now.
Another thing to note here is that this also only happens as we have the one big
Makefile with includes. If we go back to per directory Makefiles this problem
should vanish as well. In any case we need a solution for 1.18 now and this is
what I have to offer. If you have a cleaner solution in mind feel welcome to
test it out and if everything we need keeps working (make, make examples,
make check, make benchmark, make dist and make distcheck) go ahead.
Summary:
this removes the cares/ares based resolver and the compiled-in dns.c
resolver, modified the getaddrinfo based resolver to use threads not
forking (almost halving its size) and now makes that the only resolver
we have. getaddrinfo handles ipv6 and ipv4 (according to docs). this
simplifies code paths, drops code size of the efl tree by about 11k
lines of code, makes it easier to test and more robust to future
changes with ip resolving as it now just relies on libc. we won't have
coverity complaints on dns.c imported code anymore to fix and don't
have tokeep up with bugfixes/security from the upstream imported code.
this means we use a single resolver on all platforms (windows, mac,
linux) as opposed to before where cares was used for windows, and
dns.c on linux/mac. oh and the forking original was broken since our
move to eo too. so it couldnt even compile if enabled, letalone work.
so fix bug with missing /etc/resolv.conf that dns.c couldn't cope
with, fix testability, fix maintainability and reduce efl codebase size.
this fixes T3668

We have been putting the generated eo files and BUILT_SOURCES into CLEANFILES
several times. So far this have not been a real problem but with the elm merge
and more and more eo files showing up this did explode recently.
During make distcheck a lot of files kept being around and make complained about
them. It took some digging to find the arguments list to long error. If you want
details on this great limitation have a look here:
http://www.linuxjournal.com/article/6060
In our case we have been lucky enough that we just appened many files over and
over again. Not doing that solves the issue for now. My testing showed no
problems but if I missed something let me know.
Fixes T3386
Summary:
Changed ecore_con_connector.eo to efl_network_connector.eo as part of
migrating to efl_network.

To configure efl sources with bindings to use in nodejs add ––with-js=nodejs in configure flags to generate node files
$ configure --with-js=nodejs
and compile normally with:
$ make
$ make install
To use, you have to require efl:
efl = require('efl')
The bindings is divided in two parts: generated and manually
written. The generation uses the Eolian library for parsing Eo files
and generate C++ code that is compiled against V8 interpreter library
to create a efl.node file that can be required in a node.js instance.
@feature
This time the move of dns to static_libs in
4f24deac44 broke distcheck as the header file was
never shipped with the tarball. I would really appreciate if author and reviewer
would pay more attention.
Summary:
This lib would be used in efl_network_websocket.

this splits out out "manual" dlopen (eina_module_load) of curl into
its own .c file and special header out of ecore_con_url.c to tidy up
that code a bit and isolate our curl magic loading/handling
Summary:
This is still work in progress. I've added new file for temporary
purpose. Idea is to first eoify everything then change its namespace properly.

Summary: This is just the beginning. I tried for one class to check.
Tell me if this is fine, I'll change in other classes also. The goal
is to simplify and make our API clearer to understand to new comers.

This reverts commit 35119e7bfd.
Reverted to bring make check back in a working state. Also the way we
want to handle a more modular testing needs discussion.
Currently make check runs tests of whole EFL.Enabled running
of tests of individual modules by make check-<modulename>

This cleans up a lot of the build system. This makes everything
consistent, clean, less redundant and also fixes the issue of make clean
not cleaning up generated files.
Instead of -I$(top_srcdir)... -I$(top_builddir)... and then do it for
the .la, use the EFL_ macros to generate the contents to be used in
automake files.
There is a nasty bit that libtool will parse Makefile*.am and will not
get _DEPENDENCIES from _LIBADD and _LDADD if these are in
@REPLACEMENT@. To solve this we must explicitly set _DEPENDENCIES. The
contents of this is almost the same as _LIBADD or _LDADD with the
"_INTERNAL_" replacement name.
I hope the code will be result will be shorter and consistent as there
is less places to change when we add/remove dependencies.
Statistics are quite impressive (diffstat):

- remove EFL_LIBS and EFL_CFLAGS, use per-lib values that inherit
from EFL (general)
- add NAME_LDFLAGS and EFL_LDFLAGS for linker flags.
- LDADD (binaries) now use NAME_LDFLAGS instead of NAME_LIBS, as they
link to libname.la and that will pull in the libtool dependencies
