Subject [jira] Commented: (LUCENENET-383) System.IO.IOException: read past EOF while deleting the file from upload folder of filemanager.
Date Mon, 06 Dec 2010 06:46:11 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-383?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12967101#action_12967101
] 

chaitanya commented on LUCENENET-383:
-------------------------------------

The error is throwing from  Lucene.Net.Store.BufferedIndexInput.Refill() method.
please check below for the code
if(this.bufferlength<=0)
{
throw new IOexception("read past EOF");
}

But we don't know when this bufferlength becoming Zero.

Neal mentioned that .....It is possible that the document "id" that they are attempting to
delete from the Lucene index does not exist.May be the above error comes in this case.

But the file exists in upload folder.And what we found is when deleting the file..we are getting
above eroor,but  anyhow the file is deleted..only annoying thing here is if the file deletion
happens successfully also..we are getting this error.

What i felt is once after deleting the file...lucene again searching for the "ID" for second
time..that time "id" is not available..hence the error coming.

if this is the situation , why Lucene is searching for this "Id"..two times..for only one
request?
