             Summary: bin/post command not working when run from crontab
                 Key: SOLR-13422
                 URL: https://issues.apache.org/jira/browse/SOLR-13422
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: scripts and tools
    Affects Versions: 7.7.1, 7.5
            Reporter: Carsten Agger


I'm working with a script where I want to send a command to delete all elements in an index; notably,

{{}}{{/opt/solr/bin/post -c <my collection> -d  "<delete><query>*:*</query></delete>" }}

 

When run interactively, this works fine.

However, when run automatically as a cron job, it gives this interesting output:

{{ }}{{Unrecognized argument:   "<delete><query>*:*</query></delete>" }}
 {{ If this was intended to be a data file, it does not exist relative to /root}}

The culprit seems to be these lines, 143-148:

{{         if [[ ! -t 0 ]]; then            MODE="stdin"          else            # when no stdin exists and -d specified, the rest of the arguments            # are assumed to be strings to post as-is            MODE="args"}}

This code seems to be doing the opposite of what the comment says - it sets MODE="stdin" if stdin is NOT a terminal, but if it IS (i.e., there IS an stdin) it assumes the rest of the args can be posted as-is.

On the other hand, if the condition is reversed, my command will fail interactively but not when run as a cron job. Both options are, of course, unsatisfactory.

It _will_ actually work in both cases, if instead the command to delete the contents of the index is written as:

{{echo "<delete><query>*:*</query></delete>" | /opt/solr/bin/post -c departments -d}}

I've confirmed this bug in SOLR v. 7.7.1 and 7.5 - it is presumably present in more versions.

I've raised the issue on the solr-user mailing list, where I was asked to file a Jira report.
