so library somewhere is causing an exit(1) sometimes... this means i
lose my entire desktop. this is not e doing it... so it's some
dependency bug and this shouldn't happen - but it does and it causes
the entire login session to be losst, so treat an exit code ofr 0 as a
clean exit, and anything else as a bug to be handled like segfaults
etc. and restart e.
This fixes a build break on FreeBSD. Guarding as per other
blocks. These guards can be removed at a later stage as OpenBSD
has removed malloc.h and FreeBSD is in the process of
reintroducing it after a failed attempt to deprecate the header.
For consistency's sake keep these blocks identical within the
tree. We can nuke these later when FreeBSD make their minds up.
it used ot be a separate process to run to hide e starting in the bg
on a slow hdd loading modules etc. but due to compisitng and other
changes its all internal now, so keep it on always as it guarantees a
better smoother experience with less complexity to maintain.
use less stack with smaller "just big enough" alloca'd string buffers.
as e_start hangs around looking after e all day, using a bit less mem
is a good thing.
@opt
this means no leaked fd's between restarts too. cleaner. it also
encorces "die with parent" for enlightenment_start too as another
bonus in addition to its own fifo handling for singleton access per uid.
WARNING: you need to log out and log back in since the "protocol
expectations" (what exit codes do what and what parent and child
process are responsible for) changed so to get them both back in sync
you need to log out and in.
we'd have corrupted env vars with the alloca code we had to store the
env var, so always malloc it at all times. as we won't (likely) be
calling env_set() multiple times for the same environment we won't be
leaking, and at worst - not very much at all.
@fix
so often enough i find e_alert is hung and you have to kill it to get
e back. this ends upo exiting and logging you out. this is not good.
the defaul should be to restart not to dump you out and lose
everything. so switch these around to be more user-friendly.
on the cards is to redo e_alert to be simpler (use full efl stack) and
thus hopefulyl be reliable in wl mode etc.
is e crashes, catches it and restarts while locked you end up
unlocked. this lets enlightenment_start know this lock down state and
it sets an env var to ensure locking happens on restart after recovery.
"
I have a directory at the head of my PATH that contains alternate
versions of command line utils like grep, ls, etc., but E puts
/usr/bin ahead of it, overriding my tools of choice with the system
defaults.
If my understanding is correct, the only way currently to have
directories that E prepends to your PATH appended instead is to use
-i-really-know-what-i-am-doing-and-accept-full-responsibility-for-it.
I'd like to see a more sane option if there isn't one already.
Alternatively, I wonder if it wouldn't be a better idea to only
prepend directories to PATH if they aren't already contained within
it--thereby preserving the user's desired search order.

this should fix T5953
@fix
e_start isnt really using evas atm - cserve2 env vars arent being set
so remove it - e_start can start a little faster with less linking...
good for startup time perhaps and mem footprint of e_start while it
babysits
if a file called ~/.e-mtrack existed then during startup the launcher would
read the first line of this file and set LD_PRELOAD to that value
CID 1039785
Summary: Building without ptrace (on OSes which do not support it, like OpenBSD) did not work, because the fallback code had small typos.

;) _e_ptrace_attach function should return an integer value...

huge fustercluck commit because there wasn't really a way to separate out the changes. better to just rip it all out at once.
* compositor and window management completely rewritten. this was the goal for E19, but it pretty much required everything existing to be scrapped since it wasn't optimized, streamlined, or sensible. now instead of having the compositor strapped to the window manager like an outboard motor, it's housed more like an automobile engine.
** various comp structs have been merged into other places (eg. E_Comp_Zone is now just part of E_Zone where applicable), leading to a large deduplication of attributes
** awful E_Comp_Win is totally dead, having been replaced with e_comp_object smart objects which work just like normal canvas objects
** protocol-specific window management and compositor functionality is now kept exclusively in backend files
** e_pixmap api provides generic client finding and rendering api
** screen/xinerama screens are now provided directly by compositor on startup and re-set on change
** e_comp_render_update finally replaced with eina_tiler
** wayland compositor no longer creates X windows
** compositor e_layout removed entirely
* e_container is gone. this was made unnecessary in E18, but I kept it to avoid having too much code churn in one release. its sole purpose was to catch some events and handle window stacking, both of which are now just done by the compositor infra
* e_manager is just for screensaver and keybind stuff now, possibly remove later?
* e_border is gone along with a lot of its api. e_client has replaced it, and e_client has been rewritten completely; some parts may be similar, but the design now relies upon having a functional compositor
** window configuration/focus functions are all removed. all windows are now managed solely with evas_object_X functions on the "frame" member of a client, just as any other canvas object can be managed.
*** do NOT set interceptors on a client's comp_object. seriously.
* startup order rewritten: compositor now starts much earlier, other things just use attrs and members of the compositor
* ecore_x_pointer_xy_get usage replaced with ecore_evas_pointer_xy_get
* e_popup is totally gone, existing usage replaced by e_comp_object_util_add where applicable, otherwise just placed normally on the canvas
* deskmirror is (more) broken for now
* illume is totally fucked
* Ecore_X_Window replaced with Ecore_Window in most cases
* edge binding XWindows replaced with regular canvas objects
* some E_Win functionality has changed such that delete callbacks are now correctly called in ALL cases. various dialogs have been updated to not crash as a result
comp files and descriptions:
e_comp.c - overall compositor functions, rendering/update loop, shape cutting
e_comp_x.c - X window management and compositor functionality
e_comp_wl.c - Wayland surface management and compositor functionality
e_comp_canvas.c - general compositor canvas functions and utilities
e_comp_object.c - E_Client->frame member for managing clients as Evas_Objects, utility functions for adding objects to the compositor rendering systems

feature: new compositor
removal: e_border, e_container, e_popup
1. clear out environment as best is possible before executing
anything. especially PATH and IFS are set to minimal base defaults.
also use clearenv() if available and unsetenv()
2. remove gdb method as it's just too dangerous. run it as normal as
the user and if the kernel / distro dny that - then sorry. too bad.
Summary: If cserve2 crashes, enlightenment_start will respawn it again.
Test Plan:
Start E18 (in Xephyr maybe) with E_CSERVE set.
Randomly kill evas_cserve2 and enlightenment, and log out from E.
I need review for this patch as I'm not sure about all the ptrace stuff
lying around.
