Subject [jira] [Commented] (SOLR-4470) Support for basic http auth in internal solr requests
Date Tue, 05 Mar 2013 21:20:14 GMT


Jan Høydahl commented on SOLR-4470:

Wow. That was some bulk of information :) Skimmed the code - very good that you have extensive
test coverage, some JavaDocs etc. It would in my eyes be wiser to split the elephant in order
to attract committer attention. Is there some major part you can leave out and start with
the simplest possible codebase to enable simple auth on internal requests only? Then once
that is reviewed and committed (to trunk), you could add the rest in a few more steps. I'm
afraid there is a risk this patch will rot and become stale and un-applyable very very quickly,
both because it is too much in one bite and that it touches so many lines that it will not
apply cleanly for many days in a row.

Another option is to do the finalization of auth in a new branch. Just a pity non-committers
can't work with branches in svn. I could create a branch off trunk for you and commit your
code to it if you're willing to make it apply. Then everyone can more easily checkout the
branch, test, create new JIRAs with diffs against the branch and get some Heavy Committing™.

PS: Please run ant precommit - You'll want Mark & Yonik on your side here :)

> We want to protect any HTTP-resource (url). We want to require credentials no matter
what kind of HTTP-request you make to a Solr-node.
> It can faily easy be acheived as described on
This problem is that Solr-nodes also make "internal" request to other Solr-nodes, and for
it to work credentials need to be provided here also.
> Ideally we would like to "forward" credentials from a particular request to all the "internal"
sub-requests it triggers. E.g. for search and update request.
> But there are also "internal" requests
> * that only indirectly/asynchronously triggered from "outside" requests (e.g. shard creation/deletion/etc
based on calls to the "Collection API")
> * that do not in any way have relation to an "outside" "super"-request (e.g. replica
synching stuff)
> We would like to aim at a solution where "original" credentials are "forwarded" when
a request directly/synchronously trigger a subrequest, and fallback to a configured "internal
credentials" for the asynchronous/non-rooted requests.
> In our solution we would aim at only supporting basic http auth, but we would like to
make a "framework" around it, so that not to much refactoring is needed if you later want
to make support for other kinds of auth (e.g. digest)
> We will work at a solution but create this JIRA issue early in order to get input/comments
from the community as early as possible.
