Summary: ArrayIndexOutOfBoundsException when using n=50 as URL
query parameter
Classification: Development
Product: opengrok
Version: unspecified
Platform: ANY/Generic
OS/Version: All
Status: NEW
Severity: minor
Priority: P3
Component: webapp
AssignedTo: [email protected]

When using n=50 as a query parameter the third page of results will throw an
ArrayIndexOutOfBoundsException. For a live example, go to
http://src.opensolaris.org/source/s?n=50&start=0&q=String&sort=relevancy&project=opengrok,
and click on page 3. This can also happen with other values of n, for instance
http://src.opensolaris.org/source/s?n=10&start=0&q=String&sort=relevancy&project=opengrok,
page 13.
I believe this happens because the code caches (cachePages * hitsPerPage) hits
which by default is (5 * 25) = 125. When using n=50 (or n=10) the results run
out right in the middle of the page.
The above testcases used to produce more information indicating the that the
index was 125 and a stack trace blaming Results.java:70. I believe the line in
question is
http://www.norbye.org/hg/opengrok/trunk/index.cgi/file/9b89f82c1910/src/org/opensolaris/opengrok/search/Results.java#l70
.
Right now this information is missing and only "null" is printed. This may be
a separate bug.
