David Smiley created SOLR-8946:
----------------------------------
Summary: bin/post script stdin detection is faulty
Key: SOLR-8946
URL: https://issues.apache.org/jira/browse/SOLR-8946
Project: Solr
Issue Type: Bug
Components: SimplePostTool
Affects Versions: 6.0
Environment: Ubuntu
Reporter: David Smiley
Summary: I think the {{post}} bash script tries to detect stdin the wrong way.
If I run "post -h" I see some examples, to include this:
{code}
echo '{commit: {}}' | bin/post -c my_collection -type application/json -out yes
-d
{code}
However if I try it, Solr returns this error: {{Cannot parse provided JSON:
JSON Parse Error: char=<,position=0 BEFORE='<' AFTER='add/>'}}
I see that {{post}} is sending an {{<add />}} in certain cases, but it's not
supposed to when the mode is stdin. Looking closer, it appears to be because
of this line:
{{if [[ -s /dev/stdin ]]; then}}
If I change it to this (which I figured out after googling around; I'm no bash
expert!):
{{if [[ ! -t 0 ]]; then}}
Apparently '0' represents stdin. It works for me. [~thelabdude] might you
take a look? I'd be happy to add a formal patch & commit for this trivial
change but it really needs other eyes.
