Can't relaunch Nuvola-app or launch second Nuvola-App

[laramy2020]

System: Arch Linux 4.12.14-1 x86_64
DE: Gnome 3.24.3
nuvola --version:

Web Apps - based on Nuvola Apps™ project
Version 4.7.0
Revision snapshot
Diorite 4.7.0
WebKitGTK 2.16.6
libsoup 2.58.2

Affects all nuvola-apps

How to reproduce.

• Launch nuvola via the Web App Desktop shortcut, The dedi nuvola-app shortcut, or running nuvola in the commandline
• Close the Web app.
• Launch any web app using any of the same 3 steps above

Error dialog pops up saying:

app can not start
Failed to connect to nuvola app runtime service
Error message: Failed to connect to socket 'N3'. Connection refused

This issue prevents 2 nuvola-apps from running at the same time as well.

To kill the service I run
pkill -f nuvola
Forgot to mention. These are compiled builds. Using update PKGBUILDS found in the aur
AUR
And
GitHub

Hello @laramy2020. Thank for reporting this issue. Does it still affect Nuvola 4.8? If so, could you provide me with debug logs (nuvola --debug)?

Using update PKGBUILDS found in the aur

Off topic but you pass --webkitgtk-supports-mse to Nuvola's build. Are you 100% sure that Arch Linux builds of WebKitGTK+ support MSE (-DENABLE_MEDIA_SOURCE=ON)?

The program still hangs
nuvolaout.txt
I don't have dbus launcher enabled yet. I am aiming for enabling that once i get all packages managed/maintained in the aur. If that might help i will give that a try as well.

I did not see that flag exactly. But I did a recursive grep of "ENABLE_MEDIA_SOURCE" in the source files (including the PKGBUILD) and i got returns of all ENABLE_MEDIA_SOURCE=ON

So that was everywhere, just not in the build script.
If there is a way I can confirm an installed package, that would be great.

If the source requires DENABLE_MEDIA_SOURCE=ON for the build to be enabled i can add that to my PKGBUILD libs.

Ok looks like things have changed from 2.16 to 2.18 i might have to make a modified webkitgtk build in the aur.

I cannot see any sign of an error in the log. It shows that Google Play Music started and exited successfully, nothing more.

If there is a way I can confirm an installed package, that would be great.

Check window.MediaSource in WebKit WebInspector. Nuvola 4.9 will do that for you though (since 1d8c398). If you need more info, start a new topic at nuvola-devel mailing list.

Looks like arch dose not enable MSE. Will be making that package now as well...

I plan on making a new debug build tomorrow in a clean arch install. I will grab logs and videos.

Attached are two more logs and the system it was tested on
systempackages.txt
system.txt

nuvola.log
nuvola2.log

And a video of the 3 machine I have with this issue (all 3 have this issue) Video

And the updated AUR PKGBUILD

There obviously is an issue with a socket connection from the youtube subprocess to the master process. A relevant code in Diorite might be:

grep -rn "Failed to connect to socket" src
src/glib/io.vala:57:		throw new IOError.CONN_FAILED("Failed to connect to socket '%s'. %s", path, e.message);
src/glib/SocketChannel.vala:64:			throw new IOError.CONN_FAILED("Failed to connect to socket '%s'. %s", name, e.message);
src/glib/SocketChannel.vala:78:			throw new IOError.CONN_FAILED("Failed to connect to socket '%s'. %s", name, e.message);

@laramy2020, Diorite master now produces three unique error messages instead of "Failed to connect to socket". Could you post new debugging output once this changeset reaches your builds (Diorite 4.9)?

Nuvola 4.9 is out ;-)

[laramy2020]

Awesome. will do soon. Been a busy month, but my scripts seem to be working on making new pkgbuilds.
