Subject [jira] [Commented] (HADOOP-11745) Incorporate ShellCheck static analysis into Jenkins pre-commit builds.
Date Wed, 25 Mar 2015 00:12:52 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14378985#comment-14378985

Chris Nauroth commented on HADOOP-11745:

bq. I've been meaning to look at how exceptions are handled for some of the Java-bits but
I hadn't gotten that far yet.

I think the closest analogy in the Java world is our Findbugs exclude files.  These are XML
files that describe points in the code that trigger Findbugs warnings that we have agreed
are spurious.  I think the {{shellcheck disable}} comments are similar.  I think if we keep
using that, then it would work out fine.

bq. At this point, I think/hope the only things left to really look at is dev-support itself.

Yes, that's a good point.  I do see a lot of warnings in the dev-support scripts.  If this
gets intractable, then I suppose as a first step we could chicken out and filter dev-support
from the ShellCheck results.  :-)

>          Components: build, scripts
>            Reporter: Chris Nauroth
>            Priority: Minor
> During the shell script rewrite on trunk, we've been using ShellCheck as a static analysis
tool to catch common errors.  We can incorporate this directly into Jenkins pre-commit builds.
 Jenkins can reply with a -1 on shell script patches that introduce new ShellCheck warnings.
