Hi all,
we are starting to do the final testing with the new release of Subtext
which has a Lucene.net based search engine.
But we are finding a strange error, related to a SecurityPermission when
running in medium trust
there is the stack trace of the error:
[SecurityException: Request for the permission of type
'System.Security.Permissions.
SecurityPermission, mscorlib,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
failed.]
FileSupport.Sync(FileStream fileStream) +0
Lucene.Net.Store.FSDirectory.Sync(String name) +151
Lucene.Net.Index.SegmentInfos.FinishCommit(Directory dir) +171
Lucene.Net.Index.IndexWriter.Init(Directory d, Analyzer a, Boolean
create, Boolean closeDir, IndexDeletionPolicy deletionPolicy, Boolean
autoCommit, Int32 maxFieldLength, IndexingChain indexingChain,
IndexCommit commit) +257
Lucene.Net.Index.IndexWriter.Init(Directory d, Analyzer a, Boolean
closeDir, IndexDeletionPolicy deletionPolicy, Boolean autoCommit,
Int32 maxFieldLength, IndexingChain indexingChain, IndexCommit commit)
+110
Lucene.Net.Index.IndexWriter..ctor(Directory d, Analyzer a,
MaxFieldLength mfl) +369
Subtext.Framework.Services.SearchEngine.SearchEngineService.EnsureIndexWriter()
in SearchEngineService.cs:93
The line of code that causes the error is
_writer = new IndexWriter(_directory,
_analyzer,IndexWriter.MaxFieldLength.UNLIMITED);
where _directory is
FSDirectory.Open(new
DirectoryInfo(HttpContext.Server.MapPath("~/App_Data"))))
We are using one of the latest versions (retrieved from the trunk around the
beginning of January) .. 2.9.1 I guess
I read you should have fixed the problem in 2.3.2 (
http://issues.apache.org/jira/browse/LUCENENET-169) but this problem is
happening again here.
Any idea on what is happening here?
Thx
Simone
