c – mq_open() – EACCES, Permission denied – Stack Overflow

While testing the GitHub integration (#295), I got some file permission errors when checking out a branch. After some investigation, it seems that this is caused because Windows considered the files to be currently open by a different application: https://community.atlassian.com/t5/Git-questions/Windows-permission-denied-on-switching-branches/qaq-p/407440

I ran a test, and I was able to trace the problem to the language server. Here is my test procedure. My test environment is Windows 10, version 1703, Java 1.8.0_161.

1. Open a project in Moonshine
2. Manually kill the language server
3. Checkout a different branch from the command line
4. Run “git status” – The output does not show any errors
5. Reopen the project in Moonshine – the language server starts again
6. Checkout a different branch from the command line
7. The language server reports errors
8. Run “git status”. The output shows file permission errors
9. Close Moonshine
10. Run “git status” – The errors are cleared

Here is the output from the language server. On futher review, it looks like just indicates that the language server is recompiling multiple times:

: Failed to get compile settings for  configname=flex.
: 
: Failed to get compile settings for  configname=flex.
: 
: Failed to get compile settings for  configname=flex.
: 
: Failed to get compile settings for  configname=flex.
: 
: Failed to get compile settings for  configname=flex.
: 
: Failed to get compile settings for  configname=flex.

Here is an example of the file errors that I am seeing with “git status”:

C:FlexworkspaceMoonshine-IDE>git status

On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

Expected output (this is displayed after Moonshine is closed):

C:FlexworkspaceMoonshine-IDE>git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

These errors prevent me from checking out another branch with Git.

@joshtynjala, have you seen a problem like this before? In theory this could affect the language server with VSCode as well.

@rat-moonshine, my proposed solution is:

1. User tries to checkout a branch (or a similar operation)
2. Moonshine stops the language server(s) associated with that project
3. Moonshine executes the checkout
4. Moonshine restarts the language server

Is this sufficient (see below)? It’s just the output from VS Code Dev-Tools.
Else: Could you give me a hint? I know PHP and XDebug in a Web-Environment, but failed to make a XDebug Trace for a CLI Process started through VS Code (NodeJS).

Besides that: While playing around, I also discovered, that this happens only with Projects that are stored in my OneDrive Folder. Looks like a OneDrive Client Update ~2 month ago introduced this. Pausing OneDrive Sync doesn’t help.
Don’t know, if that’s also the cause of @nmss ‘ problem.
