Freeze when adding repository

[slopez31]

Hi everybody,
I have à little issue when i'm a trying to add a collaboration workspace (actually it's not on every computer 2/3). (with last beta version 3.2).

Archi freezes during "Fetching..." message

Killing "Windows Host" Subprocess unblock and download the map.
After this and until now everything seems to be fine.

My git server is a gitlab on premise server.

Thanks and good work to all.

I won't be able to diagnose this without more information. Can you try and narrow things down?

Hello Phillipus, I think i can reproduce the issue, what can i do to help you to debug ? Maybe there is a log file ?

[slopez31]

Hi again,
Maybe this will help you

the bash command is called with : bash --login -c "which git"
And if the linux sub-system is not deployed it wait for a key to be pressed.

Need to know:

• Archi version
• Model Repo version
• Steps to reproduce - what exactly leads to the freeze?

[slopez31]

Archi version 4.2.0
Model Repo Gitlab : GitLab Enterprise Edition 10.5.4-ee
Windows 10 enterprise Version 10.0.16299 Numéro 16299

The steps are simple, with fresh install I just used the green button "Import remote model to workspace" , and fill the form with server, user password. and finaly fhe "Progress" windows stop on fetching and archi is completely freezed.

[Phillipus]

Which version of the the Model Repo Plugin?

[Phillipus]

Why is "Windows Host" Subprocess running under Archi? I dont's understand what all the Bash and other stuff has to do with this. Is this problem only on this machine with all this stuff? You have to narrow down the problem, because I can't diagnose it.

I think the probem is after this

Maybe the subprocess is invoke in the jgit lib . Unfortunately, I'm not skilled enough to debug deeper or to propose a patch.
I'm going to continue to kill manually the subprocess, it's a good way to avoid the issue.

Bye and thanx a lot for the plugin

OK, I found out that JGit sometimes invokes bash to find global git settings:

Perhaps it is getting stuck here. Need to investigate why.

[Phillipus]

Looking at that JGit code...

If JGit can't find a native git executable in system PATH it then looks for "bash" in the system PATH. If it finds "bash" it will try to invoke it with "bash --login -c which git" command in order to find git. This seems a dumb thing to do.

Workaround would be to install git somewhere and make sure it's on the PATH, or remove "Bash" from PATH.

But we need to figure out why invoking bash is freezing. - I know

What bash have you got installed? OK, I know now.

I've filed a bug report for JGit:

@slopez31 You could workaround this by:

1. Open Control Panel, "Programs and Features", "Turn Windows features on or off"
2. In the dialog untick "Windows Subsystem for Linux"
3. Reboot.

@Phillipus Thanks for the tip.

Or install git and ensure it's on the PATH.

The ideal solution is the JGit guys remove the dumb "search for bash" thing.
