Validation Command stderr output missing

[ghost]

Place in Dashboard: Validation > Standard error (stderr) Place in Code: lib/clientScripts/validate_file.py (around 145)

Expected behaviour ... failed with exit status 1; stderr: here are details to this error ...

Current behaviour ... failed with exit status 1;

Steps to reproduce Step Validation fails -> Details-Symbol -> See Text in "Standard error (stderr)"

Additional Infos I cross-checked the previous commit with the latest changes since in am-1.7 i did not have this problem and it appears that the last line of the previous Codepart:

print('Command {description} failed with exit status {status};'
                  ' stderr:'.format(
                      description=rule.command.description,
                      status=exitstatus),
                  stderr, file=sys.stderr)

has been removed completly, compared to the latest Codepart:

self.job.print_error(
                'Command {description} failed with exit status {status};'
                ' stderr:'.format(description=rule.command.description,
                                  status=exitstatus))

, which always results in stderr: nothing

HI @VinzenzBauer , thanks for filing. Just a few follow up questions:

• which job is this happening in? In the validate micro-service or other (validation also happens in Normalization, for example)
• are you experiencing the same behaviour in other microservices/jobs or just this one?
• have you disabled task output (see: https://www.archivematica.org/en/docs/archivematica-1.8/admin-manual/installation-setup/customization/task-config/#task-output-capturing-admin). Even if you had, you should still see output for non-zero exit codes but just thought I'd check.

• The job we run is Validate formates in Transfer: Validation
• Just this one yet, as we wanted to check wheter our custom Validation Command: Tool was still doing its job from 1.7 or not. We used stderr for output which seems to not work atm. The only output we see in the microservice-details is this:

Standard streams Standard output (stdout)

Running Validate using CheckitTiff Running Validate using CheckitTiff_upcoming

Standard error (stderr)

Command Validate using CheckitTiff failed with exit status 1; stderr: Command Validate using CheckitTiff_upcoming failed with exit status 1; stderr:

• We have not disabled the task output, we rather rely on it
• I noticed that JHOVE for example still produces readable output on failing, i will check that now. Still, when usingprint >> sys.stderr, "..." the output will not be shown on exit status 1 which is, i belive due to the missing code i mentioned before. Please let me know if there will be a fix for this in the future.

Took me a while, i put the error-out to eventOutcomeDetailNote which works almost like the print >> sys.stderr, in AM 1.7.

This issue does not have priority to me anymore but i'd still like to see that the sys.stderr will be shown again. Thank you.
