efl seemingly has been broken on freebsd for a while - environ the
symbol does not exist for SHARED LIBS on freebsd (discussin had been
had on this already, but i gave up). use dlsym as the escape mechanism
so we build on freebsd again.
This reverts commit a57c7f7510.
I pretty much hate to just revert your revert, but you failed to read my
replies, and failed to understand what i was talking about.
And YES we talked at fosdem about the platform issue, and do you
remember my answer, that back in time this might be the case, today is
different freebsd suppoerts setenv, and for windows we have a setenv
implementation in evil. And yes, vtorri also created a issue how bad and
evil this commit is, however, i still fail to see the issue since setenv
unsetenv and clearenv usages are taken as needed. (T7693)
The ownership question is answered in
https://phab.enlightenment.org/D7516#137367.
Can we please get into a state of technical discussions, and not *oh
shit, i am going to revert this* this has been in review for a long
time, a lots of people have tested it, we discussed things on it, and
there was 3 weeks of no reply from you.
The issues that exist will be dealed with. Feel free to create tasks if
you want :)
setenv and unsetenv are not portable. i explained to you at fosdem
there are issues and it's why i used putenv in the original
implementation and even though it's a pain (the string tou pass to
putenv is a pointer used literallt from there on in and you get it
from getenv, thus making ownership a pain -this is a libc issue we
can't readily solve). use putenv like the original code. then put it
back in. vtorri now has windows porting issues with the setenv use. i
knew there was a reason that still existed...
in addition your in_sync stuff is broken. psuedocode:
// assuming BLAGH env is not set to anything here
c = efl_core_env_get(global_env, "BLAH");
...
putenv("BLAH=10");
...
c = efl_core_env_Get(global_env, "BLAH");
i will get NULL in both cases for c ... but i should get "10" for the
2nd in reality. reality is lots of code across application code and
libraries will at times mess with the environment. it has to work with
this. the prior implementation did work with this.
Revert "ecore: here comes a env object"
This reverts commit 2373d5db5b.
Revert "efl_task: remove env from this object"
This reverts commit c3d69f66a6.
Revert "ecore: get rid of commands in efl_task."

Revert "ecore: here comes a command line object"
This reverts commit 48e5684b3c.
1. this is broken:
EOLIAN static const char*
_efl_core_command_line_command_get(const Eo *obj EINA_UNUSED, Efl_Core_Command_Line_Data *pd)
{
return eina_strdup(pd->string_command);
}
it returns a const char * BUT it duplicates it on return. no. a big
fat honking NO. return a char * or don't duplicate. pick.
2. _efl_core_command_line_command_array_set() is broken by design. it
accepts an array of strings, but the strings are owned by the caller
who creates the array (requiring they free them up themselves after
this call) but the array becomes owned by the callee. the code here frees the
incoming array but doesn't care about the string content of it. it's
leak heaven waiting to happen (or bugs when someone wants to access
the array they create to walk it to free the strings they put into it
after it is set).
i brought this up and it was dismissed. now exactly he issue i brought
up is there with mixed ownership and the added complexity as well as
transfer of some ownership but not others.
go back and think about this so it isn't broken by design.
Note that the usage in efl_thread.c should and could be removed.
the problem with its usage is that when the ARGUMENTS event is fired,
noone ever had the chance to subscribe to the loop of the thread yet. So
all in all this is unneccessary, since noone could ever touch that.

If you need data, use a efl_future_then as done in every case here to get the same feature.

This reverts commit 9b5155c9f1.
For now lets revert this, this breaks copy and paste, further more it
has the potential to break a lot more things, as eio_model tends to use
efl_loop_promise new, and then eina_promise_data_set, which is
explicitly forbidden.
This fixes crashing terminology instances.
This changes a lot of things all across the EFL. Previously,
methods tagged @const had both their external prototype and
internal impl generated with const on object, while property
getters only had const on the external API. This is now changed
and it all has const everywhere.
Ref T6859.
127 is the "command not found" shell exeit code, 126 is "the command
file is found but is not executable" which i think i'd interpret not
just for execute permissions but that something is preventing it from
executing in general.
both exe and thread objects must (currently) stay around until the
child thread or exe (task) is done. if you don't do this "bad things
can happen". so produce an error to let the programmer know.
so the MAIN loop is actually an efl.app object. which inherits from
efl.loop. the idea is that other loops in threads will not be efl.app
objects. thread on the creator side return an efl.thread object.
inside the thread, like the mainloop, there is now an efl.appthread
object that is for all non-main-loop threads.
every thread (main loop or child) when it spawns a thread is the
parent. there are i/o pipes from parnet to child and back. so parents
are generally expected to, if they want to talk to child thread, so
use the efl.io interfaces on efl.thread, and the main loop's elf.app
class allows you to talk to stdio back to the parent process like the
efl.appthread does the same using the efl.io interfaces to talk to its
parent app or appthread. it's symmetrical
no tests here - sure. i have been holding off on tests until things
settle. that's why i haven't done them yet. those will come back in a
subsequent commit

they are just my test code for this.
Please see this design document:
https://phab.enlightenment.org/w/efl-loops-threads/
Some glibc versions declare pipe(2) with a warn unused result attribute,
leading to compile-time warnings when pipe(2)'s return value is not
checked.
If pipe(2) fails, we now print an error and make the calling function
fail.
this is astart of the work for having a common task class/interface
between loops, threads ane exe's so the i/o is all symmetric and works
the same way between all of them as well as similarly for launching
and knowing when the exit etc. etc.
this is not final and not perfect, but it's a start. comments of
course welcome
