Subject [jira] Created: (MINDEXER-13) *.gz index not loadable using default LightweightHttpWagon
Date Thu, 24 Mar 2011 13:47:22 GMT
*.gz index not loadable using default LightweightHttpWagon
----------------------------------------------------------

                 Key: MINDEXER-13
                 URL: http://jira.codehaus.org/browse/MINDEXER-13
             Project: Maven Indexer
          Issue Type: Bug
    Affects Versions: 4.0.0
         Environment: Ubuntu, JDK 6u24
            Reporter: Jesse Glick
         Attachments: MINDEXER.diff

If you create a new-style index (without {{--legacy}}), publish on an HTTP server (Apache
2.2.9 in my case), and try to download the remote index from a client using the default {{LightweightHttpWagon}},
the download fails.

The wagon upon seeing {{Content-Encoding: gzip}} automatically decompresses the index and
serves the raw data. {{IndexDataReader}} then passes this to {{GZIPInputStream}} which chokes.
(MINDEXER-12 then conceals the actual problem and makes it look like the indexer only accepts
the legacy format.)

Have a patch which seems to work. Probably {{DownloadRemoteIndexerManagerTest}} needs to be
enhanced to check this case; I am not very familiar with Jetty so I have not tried this yet.

(Nexus sends {{Content-Type: application/x-compressed}} but no content encoding so the problem
is not visible when using a Nexus mirror.)
