Occasionnal hdiutil: create failed - Resource busy

[gaetschwartz]

When creating a DMG in my CI (Bitrise), the tool occasionally fails with hdiutil: create failed - Resource busy.

I'm using the latest version (1.10).

Here is my usage of the tool:

+ create-dmg --volname 'Media Library' --window-pos 200 120 --window-size 800 529 --icon-size 130 --text-size 14 --icon 'Media Library.app' 260 250 --hide-extension 'Media Library.app' --app-drop-link 540 250 --skip-jenkins 'Media Library (7c0935e).dmg' 'Media Library.app'
Creating disk image...
hdiutil: create failed - Resource busy

This looks like some kind of race condition or a timing issue, as the tool only fails occasionally.

Hmm, our old friend - "Resource busy (16)". Maybe we need to put all "hdiutil" calls into retry loops, like "hdiutil detach" in #139 .

[gaetschwartz]

That would make sense indeed. If you have an idea of where this takes place, can try to open a PR :)

Any news on this problem? We are having the same issue on the newest macOS13 runners on GitHub and it's consistent - happening 100% of the time.

Yes, indeed, I can't find a way to bypass this now. (even with --skip-jenkins)

[VitoVan]

No, it seems there is more than 50% chance to success with --skip-jenkins on github actions macos-13.

[grzegorzkrukowski]

It's still a case, especially on macOS13-xl machines on GitHub. Here is related ticket on runners - they suspect it maybe related to XProtectBehaviorService that was introduced in macOS13

The walkaround seems to be killing the process and retrying - but it still doesn't help 100% of the time.

Hi,
we are hitting on this as well, with more frequency in the last weeks. It doesn't happen 100% of the time, but it is not helping...
Is there any workaround? Are you considering applying the workaround shared by @grzegorzkrukowski mentioned above?

Thanks

@afvieira it seems neither the workaround fixes this for sure

Since I'm unable to replicate this issue I really can't help. But any of those that replicate and can try/test, feel free to send a pull request.

I can also confirm this happens sometimes

I fixed my workflow with the following two modifications:

1. kill XProtect before calling create-dmg
2. use sudo to run create-dmg

Edit 2 days later:

It didn't fix it, just gave me more luck.

The resource is still busy sometimes.

Can confirm this happens consistantly on GitHub Actions Mac M1 Runners. The duild doesnt fail locally on M1 macs thought.

Details of the GitHub Actions run can be found here: https://github.com/phcode-dev/phoenix-desktop/actions/runs/7626006956/job/20771494599.

Is there any fix planned for this? Not being able to build mac M1 DMGs sounds like a pretty big issue.

I'm now seeing this on my M1 Mac every build. more info on discord: https://discord.com/channels/616186924390023171/1200314563690770515/1200314563690770515

I am not using this action but by running hdiutil create I still get this error sometimes in macos-12
