I have an issue yet, and it's that I made a `make run` just for IDEs like GNOME Builder where for some reason xdg-open won't open the PDF reader (Evince here), instead opening... w3m??? I dunno I have to figure that out

checking GNOME Builder's source code just to get what's going on inside :shrug_yui: https://gitlab.gnome.org/GNOME/gnome-builder/blob/d866396eaa2f192a1c42856d0a102ceec454deb0/src/plugins/make/make_plugin.py

I think I get itI think GNOME Builder's GIO task for Make is killed before "gio run" can open the program it wants to launchlol

@espectalll I don't think there is.For me, anything I start via `xdg-open` _already_ seems to be detached from the terminal, but it seems to be my xdg-open "backend" (the DE-specific script it calls into, for me it's kde-open5) doing it (`dolphin .` blocks, `xdg-open .` doesn't).And that has drawbacks itself! Often you _want_ to wait for an application, e.g. in the case of $EDITOR.

@espectalll But that blocks, still, right?Because as I understood it the problem is that gnome-builder times out.But maybe it's not even that? Maybe it's reaping leftover processes once the first child exits or something, and for some reason with gio, it exits before starting the thing (in another process)?

@hirnbrot (the child keeps just working on its own after make is closed)

@espectalll Okay, imagine `gio run` for some reason does:- fork()- in the parent, exit immediately- in the child, do some stuff and eventually exec()Outside of the terminal, builder notices that the parent has exited and goes "Oh, this must be done, no child must be left behind" and kills all its children, so it doesn't leak ressources.Inside of the terminal, normal terminal semantics apply, so that doesn't happen.

@hirnbrot I get that's probably the issue, what I don't get is why it behaves like that?

@hirnbrot (...it could be that for some reason it's trying to kill the PDF reader on its own, using the logic you've explained?)

@espectalll So it doesn't leak ressources (leaving a nonsensical running process is basically a memleak)? To simplify the plugin's job?This is basically what systemd does when told to exit a service, and this bug is akin to what happens when the Type= setting doesn't match (see https://jdebp.eu/FGA/unix-daemon-readiness-protocol-problems.html).

@espectalll I should probably make clear that all of that is pure conjecture. That makes some form of sense to me, and would basically explain what is happening.It's also possible there's something entirely different here - maybe `gio run` needs a terminal, or it needs some env var that builder removes or sets differently?So you're probably better off waiting for an answer to your bug.
