> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: scripts and tools
> Reporter: Hoss Man
> Priority: Major
>
> one of our users (matt__) spent all day on freenode#solr trying to figure out
> why a simple script he had that called {{bin/post}} would work fine when he
> ran it, but didn't seem to do anything when run as a cronjob.
> After helping him setup better logging from cron, it ultimiately came down to
> the fact that a command like this (which was the very first thing in his
> script)...
> {code}
> bin/post -c yyy -host xxx -d '<delete><query>zzz</query></delete>'
> {code}
> ...was failing with an error like this...
> {noformat}
> Unrecognized argument: <delete><query>zzz</query></delete>
> If this was intended to be a data file, it does not exist relative to
> /opt/blah/blah
> {noformat}
> Ultimately we determined that the problem was how {{bin/post}} tests for
> "stdin" -- by checking to see if it's _not_ being run in a terminal (with '
> {{! -t 0}} ') -- in which case it doesn't treat the argument after {{-d}} as
> data, and instead lets it fall through to the next iteration of the arg
> parsing loop (as either another switch, or a filename)
> the problem here being that running (in a script) as a cronjob is another
> case where {{bin/post}} is "not being run in a terminal" so the {{-d}}
> parsing would up completely ignoring the {{<delete>...}} string, evne though
> there was nothing being redirected on stdin.
> the workaround is to use {{echo}} to give {{bin/post}} some stdin, since it
> was going to expect it for any usage of {{-d}}...
> {code}
> echo '<delete><query>zzz</query></delete>' | bin/post -c yyy -host xxx -d
> {code}
