Subject [jira] Commented: (LUCENENET-357) Lucene.Net in Medium Trust (Mostly won't work on shared hosts / Mosso cloud etc due to 'Trust' levels)
Date Sat, 08 May 2010 12:57:51 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865456#action_12865456
] 

Robert Jordan commented on LUCENENET-357:
-----------------------------------------

Digy, there is a problem with your patch:

> if (variable == "OS_VERSION") return System.Environment.OSVersion.ToString();

Environment.OSVersion.ToString()  is returning something like  "Microsoft Windows NT 6.1.7600.0"
which is causing that neither WINDOWS not LINUX are correctly set.

This is a non-issue *at present* because neither WINDOWS nor LINUX actually affect something.

The only condition based on WINDOWS is used by

public static FSDirectory Open(System.IO.DirectoryInfo path, LockFactory lockFactory)

where both branches lead to the same code.

May I rewrite parts of Constants such that these values are set consistently?

> Initially I had to remove a few references to the Sys Environment to get it to work.
However now it fails use of the 'Weak Hashtable' - any reference to a 'weak[something]' will
fail with a security exception. The issue only happens when returning sorted results.
> As an example here's the web.config modified trust file I'm being forced to use on Mosso
(Rackspace cloud)
