Mac DE 2nd run of start-object-server.command kills all running apps

[AndyDentFree]

If you run the start command whilst a server is already running it can kill all your (GUI) apps.

(Changelog says this is Object Server 1.0.0-beta-4.2)

• Double-clicked on the start-object-server.command
• later, after laptop sleep, didn't realise was still running first copy
• Double-clicked on the start-object-server.command
• in the Terminal window was prompted Another instance...already running
• typed yes to terminate the other instance
• all running Mac apps died leaving only the Terminal going

This is 100% repeatable.

(full log available from Terminal window but may want to just forward privately - unsure if things like the Admin token should be public here)

@AndyDentFree What's the behaviour you would expect?

[AndyDentFree]

Expected behaviour - It should not affect any other apps. It should just replace the server instance.

When I say all running Mac apps died, I am not talking about any other apps related to Realm or Mac DE. Every single app on my machine died.

I just repeated the test on a different Mac.

As soon as I typed in yes to terminate the server instance, it killed off:

• Chrome (each process for each tab)
• Evernote
• Preview
• SourceTree

[AndyDentFree]

Just to clarify, the only things left running after the crash described above were:

• Finder
• Terminal
• Chrome, with a series of crashed windows, because every process backing them had been killed.

@AndyDentFree What is the absolute path for the start-object-server.command file?

[teotwaki]

@AndyDentFree I can't reproduce this, and neither can @radu-tutueanu. Any chance you could give more details about your setup (paths and stuff). I think that might have a fairly important impact here (especially spaces in usernames and stuff like that).

Thanks.

First run of server, after moving the folder to the user root.

Ran 2nd run with it at root and no problems

[AndyDentFree]

Run server after moving back to path that, yes, had spaces in it:

[AndyDentFree]

Yes - good call. When I moved it back to that location with spaces in the path, it killed everything.

[teotwaki]

Can you test with @radu-tutueanu's fix in https://github.com/realm/realm-sync-services/issues/540? It just adds quotes, so should be able to handle spaces in the path.

[AndyDentFree]

👍 yep, that fixed it
