it seems that on windows read() and write() won't work with sockets,
so use recv() and send().
Note that this code is still untested on windows, at least the errors
must be fetched using WSAGetLastError() instead of errno directly, but
I don't have a Windows machine I can test.
It has been discussed on the ML (thread: "[RFC] rename efl_self") and
IRC, and has been decided we should rename it to this in order to avoid
confusion with the already established meaning of self which is very
similar to what we were using it for, but didn't have complete overlap.
Kudos to Marcel Hollerbach for initiating the discussion and
fighting for it until he convinced a significant mass. :)
This commit breaks API, and depending on compiler potentially ABI.

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.
When CURLOPT_WRITEFUNCTION returns less then the requested amount,
CURL will fail, not call us back with the remaining data.
Then in such cases we must pause CURL and read nothing.
When unpausing we need to kick curl with timeout action so FD handlers
will be re-arranged.
Last but not least, sync our buffer limit with CURL, otherwise it may
always fail if we're smaller than CURL.
CURL doesn't play nice if handles are deleted or modified while it's
dispatching the callbacks, then we must not touch the CURL* easy
handle in those cases, just dissociate the handle from object and
schedule a job to do the deletion later.
Also, since from CURL callbacks we do not have the reference to the
object, if they are deleted from inside the callback, users of 'pd'
will crash. Thus keep an extra reference while the object and its
private data are in use.
The curl_multi_info_read() is used to notify of errors and
end-of-stream, if we do callback directly from there, the user may
efl_del(dialer), which will result in the "pd->easy" being destroyed
with curl_easy_cleanup() then "cm" and "cm->multi" being destroyed.
Thus postpone that action and keep a list of finished objects, calling
their event handlers which can delete the object (or siblings), thus
ref before dispatching and unref afterwards, taking care to monitor
EFL_EVENT_DEL so we do not use stale objects.

provide curl with CURLOPT_OPENSOCKETFUNCTION and keep the fd in our
private data.
This is required because on _efl_net_dialer_http_efl_io_writer_write()
we may have no fdhandler.
It happened to me while implementing the WebSocket that uses a
bi-directional communication on top of HTTP and the server sent the
whole message, CURL reads:
recvfrom(7, "...", 16384, 0, NULL, NULL) = 86
recvfrom(7, "", 16384, 0, NULL, NULL) = 0
After the empty (second) recvfrom(), CURL will remove the fdhandler:
DBG:ecore_con lib/ecore_con/efl_net_dialer_http.c:482 _efl_net_dialer_http_curlm_socket_manage() dialer=0x4000000040000005 fdhandler=(nil), fd=7, curl_easy=0x5561846ca8d0, flags=0x4
However I should be able to write to this socket, in my case I need to
reply to a PING request with a PONG.
CURL is smart and when you ask for CURLOPT_HTTPGET, it will
automatically configure UPLOAD=false. Likewise, if you ask for
UPLOAD=1 it will configure CURLOPT_PUT...
However, to do things like WebSocket we need to do a GET request where
we need to send data, then UPLOAD=true must be used.
Then use both information in order to setup the request method and
upload, using CURLOPT_CUSTOMREQUEST to force a given HTTP method.
If we delete the curl multi handle, then we should stop any timer that
was scheduled, otherwise it will use a dead or null pointer.
also add some debug to help track down when the multi handle is
deleted.
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
TCP_CORK is Linux only. TCP_NOPUSH is supposed to
do the same thing than TCP_CORK, but on BSD (including
Mac OS X).
We now check for the existance of TCP_CORK or TCP_NOPUSH,
and use the right option. If none exist, cork_{set,get}
will just fail.
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.

This removes some useless code in various places, where the
switch from eo_do() to standard function call was not properly
refactored.
This changes:
type ret = 0;
ret = my_eo_function();
return ret;
To:
return my_eo_function();
so drop trying to appease the openbsd packages and stick to "upstream
so major versions" and let users fix their systems with symlinks. also
report what we are looking for so they have a chance to symlink to
make efl happy.
at some point we should make a single simple runtime lib linker
subsystem in efl so all these errors are reported in the same way,
input libray names are listed in a simple consistent way etc. etc.
for now we have 3 locations in efl that do this and they are roughly
similar. we can unify it later.
This lets me narrow down the remaining cases of pointers across the EFL.
The void pointers will later need to be reevaluated on per-case basis and
replaced appropriately where possible/feasible.
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
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.

Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).
@feature
We used to have eo_del() as the mirrored action to eo_add(). No longer,
now you just always eo_unref() to delete an object. This change makes it
so the reference of the parent is shared with the reference the
programmer has. So eo_parent_set(obj, NULL) can free an object, and so
does eo_unref() (even if there is a parent).
This means Eo no longer complains if you have a parent during deletion.
Mostly unused vars following the removal of eo_do_ret().
However, there are some cases where the migration script got some things
wrong, and I had to manually fix them.
I just ran my script (email to follow) to migrate all of the EFL

This wasn't done correctly in the previous commit. First of all, the
order of cleanup was wrong, the cleanup area should only be called if
failures occurred after the fd allocation, not before. Also, fd should
be reinitialised to -1 once we close the socket.

Socket fd must be closed to avoid file discripter leak.

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.

This looks like an obvious case of missing break. If it wasn't a missing

Tests are not failing either way.
CID1039379
The client structure holds a file descriptor, which is not initialized (which means 0) in case of UDP as there is no client-specific socket.
However, we check for the file descriptor being positive before closing it in the client destructor, which means that we actually end up closing the 0 file descriptor.
That means that things were going crazy with real strange things happening afterwards…

Since the move to Eo, in case of error we do not need to cleanup anything when
finalize finish. The kill function was arranged to do so, but it was still emiting
an event exposing the invalid Eo object. Looking closely at the code, that should
have not happened, as there was no symetrical ADD event and the function would do
nothing else. So removing it. This prevent any potential SEGV from a function that
would catch the DEL event.

This is another cleanup in perparation for the Eo stable release.
This is no longer needed thanks to the proper error reporting with
eo_constructor()'s new return value.
The finalizer change cleans it up a bit so it catches more cases/issues.
This also means that the finalizer cleans up the object in all cases,
and not only some.
@feature.
Because we defer the deletion of this object until we get all the
responses from the network, we must manually free it. A better solution
would possibly be to just free the requests upon object deletion instead
of deferring the deletion.
@fix
From now on, constructors should return a value, usually the object
being worked on, or NULL (if the constructor failed). This can also
be used for implementing singletons, by just always returning the same
object from the constructor.
This is one of the final steps towards stabilizing Eo.
@feature
Instead of "@in type name;" we now use "@in name: type;". This change
is done because of consistency with the rest of Eolian; pretty much
every other part of Eolian syntax uses the latter form.
This is a big breaking change in the .eo format, so please update your
.eo files accordingly and compile Elementary together with the EFL.

because of missing '@{' and '@}' tags. This commit adds the missing tags
in Ecore_Getopt.h, Ecore_Con_Eet.h, and Ecore_IMF.h headers.
If connect() returns 0, we must send the ECORE_CON_EVENT_SERVER_ADD event
because it wont be given by select(). select() will ONLY notice it if connect
returns -1 with errno set to EINPROGRESS.
This bug is reproductible with 100% chance using ecore_con_telnet_client example
from https://github.com/gfriloux/examples if you connect to 127.0.0.1 instead of
of an external network ip, under FreeBSD (and likely any BSD).
Seems very rare to trigger it under GNU/Linux as it seems that connect()
doesnt want to return 0 when having non blocking sockets (or is too slow),
but it seems i was having this bug too on production servers, without being
ever able to reproduce it.

If the function jumpes to the error, the scope data is freed, this is
wrong, just the object should be destroyed, so not free, just eo_unref
the object. Cause the object is just added above the object ref count
should get 0 and obj will get removed
Test Plan: Use the ecore_con_server_client_limit_set function and set the max count to 1, at the connect of a second client the server will fail at this free.

From now on, there are 5 builtin complex types, particularly accessor, array,
iterator, hash and list. All other types are simple - they can't have a complex
part. Also, the <> now binds to the type itself, not the pointer. More builtin
complex types will be added as needed.
Summary:
The pass of the wrong pointer caused a wrong scope get call cause the the
passed pointer was not a valid eo pointer.

this fixes potential leak due to
ff652084e0 fixing a valgrind access
issue. make sure the server is in the list before handling error
conditions in case a callback sets delete_me (should never though).
this should fix T1508 - my testing seems to indicate so. test suite
succeeds, some manual tests of mine work. so is ay this is a good fix
that could fix critical segvs in apps using ecore-con - eg like
weather module in e
this fixes T1341. also it removes the pointless return value from
these two functions as the return is never used. also the ifdef in
ecore_main.c seemed wrong as it wasd using fcntl not execvp but the
ifdef was for execvp. this just never was discovered, so it's slid
under the hood for a long time.
num was changed to size_t which makes it unsigned while count is a normal
(signed) int. Comparing them does not always work as expected but in this
case we already checked if count is < 0 before and would have returned if
that would be true. Thus we can safely cast count to unsigned here as it
will be greater 0 anyway.
this makes efl ignore certain env vars for thnigs and entirely removes
user modules (that no one ever used) etc. etc. to ensure that *IF* an
app is setuid, there isn't a priv escalation path that is easy.
ERR<7807>: lib/eina/eina_binbuf_template_c.x:95 eina_binbuf_append_length() *** Eina Magic Check Failed !!!
This fix a problem where eina_binbuf was used without
calling eina_binbuf_new when ECORE_CON_REMOTE_UDP is used.
Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
inexistant DNS, or having a DNS resolution error, there isnt any event
generated for the application to know.
This is not a complete fix has you need to fix a timeout value for it to
happen, but still, it makes it possible to work around it.
More work is needed on this.
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).
NB: dns_so_submit calls dns_so_reset twice (once at start, once at end
on error). As so_reset will free so->answer the first time through,
add validity check of so->answer for the second iteration.

ecore_con_event_server_add() is never called (at least not in the
standard TCP connection case, so initialize svr->start_time in
ecore_con_server_add(). This shouldn't regress any other behaviour as
this is done at the very beginning and any later change to start_time
will still happen.

Be careful, systemd socket activation require you to always order
server socket creation in the same order as defined in the unit file.
This means ecore_con_server_add should always been in the same order
for those of them using systemd socket activation.
* rename USE_GNUTLS and USE_OPENSSL to HAVE_GNUTLS and HAVE_OPENSSL
in ecore_con, to match other modules such as Eet.
* define requirements_pc_crypto, requirements_pc_deps_crypto and
requirements_libs_crypto so modules can use that.
* move to a common check section.
