exec-process fails with: error 13 permission denied since 2.5.5-M2

[Mailaender]

To reproduce, run the following ECL script

exec-process "date" | show-alert

which will work inside the IDE but fail in the runner:

 Cause: Cannot run program "date": error=13, permission denied

This does not happen when starting the test within the IDE. It also works fine with rcptt.runner-2.5.5-M0 and rcptt.runner-2.5.5-M1.

[Mailaender]

Diff of the runner logs. Changes since M1.

[basilevs]

What is the error? Steps to reproduce? Stacktrace? Attach AUT's log, if error happens in AUT. Have you tried on 2.5.5-M3? Try recreating AUT anew in IDE.

[Mailaender]

New workspace does not help. It also happens in M3 and it only happens using the runner. I believe it is some configuration flag that gives Java more permissions, but I haven't found it yet.

[basilevs]

Runner works fine on Linux and Windows in my projects (which start a lot of external processes), so this is not reproducible. I'm closing this until we have more information to work on.

[basilevs]

BTW, in the attached runner log I see a failure to discover AUT's JRE. This should be fixed in M3. Also, the log is terminated before the AUT has started. Are you sure you've attached the appropriate log?

I used your runner.sh as a template:

What is the Java version? Could you try to reproduce on Eclipse Platform as AUT?

[Mailaender]

I use /usr/lib/jvm/java-17-temurin both as system and bundled with the application.

[Mailaender]

It runs fine using https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2024-03/R/eclipse-java-2024-03-R-linux-gtk-x86_64.tar.gz&mirror_id=1285 as AUT.

[Mailaender]

Skimming through the code I noticed this

https://github.com/eclipse/org.eclipse.rcptt/blob/b51d48801138eb299516faa49bc7faf4f0e3d495/launching/org.eclipse.rcptt.launching.ext/src/org/eclipse/rcptt/launching/ext/Q7ExternalLaunchDelegate.java#L606-L616

[basilevs]

As in runner.log I see a symptom that was supposed to be fixed in M3, could you please attach M3 runner log, which reproduces the problem?

[Mailaender]

Updated https://gist.github.com/Mailaender/a607110ec92674bb204b5ad9e2b03533#file-rcptt-log

progress: Resolving null

looks fishy

[basilevs]

I've downloaded OpenChrom and failed to reproduce the problem as described. I get permission denied errors in Runner (and not in AUT) due to invalid permissions of OpenChrom's embedded JRE:

vasiligulevich@Vasilis-MacBook-Pro exec-process %  /private/tmp/Eclipse.app/Contents/Eclipse/features/net.openchrom.jre.macosx.cocoa.aarch64.feature_17.0.11/jre/jdk-17.0.11+9-jre/Contents/Home/bin/java 
zsh: permission denied: /private/tmp/Eclipse.app/Contents/Eclipse/features/net.openchrom.jre.macosx.cocoa.aarch64.feature_17.0.11/jre/jdk-17.0.11+9-jre/Contents/Home/bin/java

exec-process works fine if a proper JRE is forced via Runner's arguments.

@Mailaender please fix your AUT and retry.

[basilevs]

I've struggled on MacOS due to spurious errors caused by invalid detection of AUT's JVM, so fixed that in #75.

[basilevs]

@Mailaender have you managed to fix the problem?

[Mailaender]

Not yet :(

[basilevs]

Please update me once AUT has correct permissions for embedded JRE.

[Mailaender]

Seems to be a problem with the .dmg repackaging.

[Mailaender]

On Linux I see another long-standing RCPTT bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=515501

Unknown file system layout of Java VM from ini file

Not sure if that is related.

[basilevs]

On Linux I see another long-standing RCPTT bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=515501

Try #75

[Mailaender]

Please update me once AUT has correct permissions for embedded JRE.

Yep, still can't reproduce. Attaching a sample project and a runner startup script. The runner was downloaded from PR.

exec-process.zip

The archive also includes runner's console output. At least auto-detection of JRE via shared library on MacOS is fixed.

[Mailaender]

Using https://www.eclipse.org/downloads/download.php?file=/rcptt/nightly/2.5.5/202405081020/runner/rcptt.runner-2.5.5-N202405081020.zip I can confirm that this issue is gone. The error message

Unknown file system layout of Java VM from ini file

is no longer displayed. I think you fixed it and I guess it was https://github.com/eclipse/org.eclipse.rcptt/pull/75.

[basilevs]

I have no further ideas how to diagnose exec-process problem. Have you tried scripts from my archive above?

[Mailaender]

You already fixed it in the latest nightly.
