Unrecognised File Extensions Crash Indexer #15

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If there is a document with an unrecognised file extension in a collection
directory Galago crashes with a NullPointerException, after printing a
message about skipping it.

Running the command:
> bin/galago build /tmp/ap1.index collections/adhoc_colls/ap1/

This occurs in the binary release of Galago 1.01 on Ubuntu 8.10.

The bug appears to be caused in the method processFile of DocumentSource ,
where it prints a message about skipping a file but attempts to index it
anyway.

Thanks for the excellent bug report.  This is now fixed and I've added a unit 
test.
