Subject [jira] [Commented] (SOLR-2586) example work & logs directories needed?
Date Wed, 22 Jun 2011 20:56:48 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053468#comment-13053468
] 

David Smiley commented on SOLR-2586:
------------------------------------

So if "work" is needed (to avoid rare error conditions if a temp directory is used), that
still leaves the question of "logs".  The only thing approaching use of this directory is
some commented-out configuration in jetty.xml. So as it stands, it really isn't used. I think
if if someone uncomments that part of jetty.xml, then they can very well make the logs directory.
 What I'm after here is a little bit of simplification for new users. I certainly don't get
any heartburn over these directories, but if someone new sees "logs" and never sees anything
go there, they might think something is wrong. And removing it is one less directory.  I say
this after updating my Solr book, walking the users through the directory layout in the 1st
chapter.  No big deal, but simplification/clarity is good.

> Firstly, what prompted this issue was me wanting to use a git solr mirror but finding
that git's lack of empty-directory support made the "example" ant task fail. This task requires
examples/work to be in place so that it can delete its contents. Fixing this was a simple
matter of adding:
> {code:xml}
> <mkdir dir="${example}/work" /><!-- in case not there -->
> {code}
> Right before the delete task.
> But then it occurred to me, why even have a "work" directory since Jetty will apparently
use a temp directory instead. -- try for yourself (stdout snippet):
> bq. 2011-06-11 00:51:26.177:INFO::Extract file:/SmileyDev/Search/lucene-solr/solr/example/webapps/solr.war
to /var/folders/zo/zoQJvqc9E0076p0THiri+k+++TI/-Tmp-/Jetty_0_0_0_0_8983_solr.war__solr__k1kf17/webapp
> On my Mac, this same directory was used for multiple runs, so somehow Jetty or the VM
figures out how to reuse it.
> Since this "example" setup isn't a *real* installation -- it's just for demonstration,
arguably it should not contain what it doesn't need.  Likewise, perhaps the empty example/logs
directory should be deleted. It's not used by default any way.
