Meld doesn't quit properly on Mojave 10.14.2

[michalgutowski]

I've noticed that after closing Meld (cmd+q), its processes are still running - as a result it's not possible to open Meld app again. I can only open it again if I first kill two Meld related processes in the terminal.

This only happens when you actually compared some files or created a blank comparison. When you simply open Meld and quit it right away there is no issue. I'm running Meld 3.19.2 (r3).

Same here, exactly same OS version and Meld version, exactly same issue.

I'll look into it this weekend. Thanks for the report.

Please check on this build https://github.com/yousseb/meld/releases/tag/osx-13

Looks better. With 3.19.2 (r4) I can re-launch Meld without problems. However I can still see Meld process running even after quitting:

$ ps -ef | grep -i [m]eld 501 32935 1 0 10:38AM ?? 0:00.02 /Applications/Meld.app/Contents/MacOS/Meld

To keep things nice and clean I should still kill that process manually.

Humm.. Not sure what is happening at your end. I'm not getting this (I used to in the previous version). Going to be harder to debug..

@yousseb This issue is gone on my machine, macOS Mojave 10.14.2 (18C54). Thanks for the quick fix!

@yousseb - try with these steps:

1. open Meld
2. check ps -ef - you will have one Meld process running
3. crate blank file comparision
4. check ps -ef - you will have two Meld processes running
5. quit Meld
6. check ps -ef - you will have one Meld process running

Are you guys still getting this issue? If you are, give this build a shot. I'm unable to fully reproduce (sometimes it happens, but it hasn't occurred to me in a long while.) This build is hopefully better. https://github.com/yousseb/meld/releases/tag/osx-15

Still happens to me. Opening Meld will spawn two meld processes and quitting just kills only one of them (the one that was created first, observation based on the pid)

+1. This is still happening with 3.19.2 (r6) on macOS 10.14.5

This is still happening for me using Meld v3.19.2 on macOS 10.15.3.

I'm invoking Meld using git diff-tool and this config:

[difftool "meld"]
  cmd = open -W  -n -a Meld --args $(cd $(dirname \"$LOCAL\") && pwd)/$(basename \"$LOCAL\") $(cd $(dirname \"$REMOTE\") && pwd)/$(basename \"$REMOTE\")
  trustExitCode = true

I noticed that I can bypass the issue if I first close all Meld diffing instances with Command-W, and only then quit the Meld app with Command-Q. If I use Command-Q without closing all diffing instances (even after saving any changes), I find zombie Meld processes.
