-------------------------------------
Summary: Concurrency bug with MMapDirectory
Key: LUCENENET-521
URL: https://issues.apache.org/jira/browse/LUCENENET-521
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Core
Affects Versions: Lucene.Net 3.0.3
Environment: Visual Studio 2012, Lucene.Net 3.0.3 via Nudget, Windows
8 64bit, 4GB DDR3
Reporter: Tamas Varga
Priority: Blocker
It seems like mmapdirectory doesnt handle concurrency
this works fine: http://pastebin.com/2kHjN1ES
This:http://pastebin.com/ay6B2Krp (note that the only diff is, that i changed
the FsDirectory.Open(newDirInfo) to new MMapDirectory(newDirinfo) )
fails with exception:
{System.ArgumentOutOfRangeException: Index was out of range. Must be
non-negative and less than the size of the collection.
Full exception here: http://pastebin.com/erZTxH3d
If in the second code example I set the concurrentTaskCount to 1, everything is
just fine.
Looks like a concurrency bug for me. I am missing something?
