SQLite installation on medium trust

Hi all.
I recently discovered Mojo and immediately started building my own site. Everything works perfectly on local machine, but big trouble came when yesterday I tried to publish it on my ARUBA server (Aruba is one of the major low cost hosting here in Italy. Thus, it runs on medium trust).

This is the error message when I try to setup the site:


[SecurityException:Could not load file or assembly on Medium Trust Level]

mojoPortal.Data.DBBannedIP.IsBanned(String ipAddress) +0

mojoPortal.Business.BannedIPAddress.IsBanned(String ipAddress) +37

mojoPortal.Web.BannedIPBlockingHttpModule.BeginRequest(Object sender, EventArgs e) +81

System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68

System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

 

I tried to recompile the SQLite mojoPortal.Data.dll with

[assembly: System.Security.AllowPartiallyTrustedCallers()]

but it doesn't work. I can't really say with kind of server I'm using as it's completely out of my reach.
(except for :Versione di Microsoft .NET Framework:2.0.50727.3603; Versione di ASP.NET:2.0.50727.3082).

Any idea or should I give up my hosting provider?

thank you in advace,

 

Marino

Re: SQLite installation on medium trust

Hi,

Unfortunately, it is not possible to use SQLite under medium trust. It does PInvokes against a native dll and this is not allowed under medium trust.

Some hosts if you inquire will move your site to a server running in Full Trust, I know DiscountASP and Crystal Tech have both done that for me in the past, so you might ask your host about it.

I have heard rumors that maybe in .NET 4.0 SQLite will be installed in the GAC so that it could run under medium trust, but it is not a confirmed rumor.

I also have my eye on csharp-sqlite, which is a port of SQLite from C to C# and thus fully managed code so it "should" be possible to use it under medium trust, but I don't think it can be dropped in as a replacement for SQLite and not sure it will perform as well as the C version.

Hope it helps,

Joe

Re: SQLite installation on medium trust

Hi Joe.
This helped a lot, indeed. I will buy some SqlServer space for my site... :)
I will give csharp-sqlite an eye if I have time.
Will tell you if I will find something.

Have a nice day (and go on with this wonderful work).

this method works ?

I modified mojoPortal.Data.SQLite package :

add  reference : Community.CsharpSqlite.SQLiteClient.dll and Community.CsharpSqlite.dll

And for each class in  mojoPortal.Data.SQLite I have replaced

using Mono.Data.Sqlite; with using Community.CsharpSqlite.SQLiteClient;

 

Now i download mojoportal-2-3-5-4-sqlite-net35-deploymentfiles.zip and  replaced the new mojoPortal.Data.SQLite .

Well now there are no more Security errors but during installation
 have this problem

Verifica del sistema...
Privilegi del File system ok.
SQLite connessione al database ok.
i privilegi per il database sono sufficienti per modificare lo schema.

An Error Occurred:More restrictions were provided than needed.
Source:Community.CsharpSqlite.SQLiteClient
Stack Trace in Community.CsharpSqlite.SQLiteClient.SqliteConnection.GetSchema(String collectionName, String[] restrictionValues) in mojoPortal.Data.DBPortal.DatabaseHelperTableExists(String tableName) in mojoPortal.Data.DBPortal.DatabaseHelperSitesTableExists() in mojoPortal.Business.DatabaseHelper.SchemaHasBeenCreated() in mojoPortal.Web.UI.Pages.SetupHome.ProbeSystem() in mojoPortal.Web.UI.Pages.SetupHome.Page_Load(Object sender, EventArgs e) in System.Web.UI.Control.OnLoad(EventArgs e) in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

:((

there is a solution to run this good cms with SQLite?
 

Bye

Re: SQLite installation on medium trust

sorry but trying to find a solution to use SQlite in medium trust is not currently a project goal, I am not planning on using or supporting CsharpSqlite.

You can use SQL CE in medium trust and get the same benefit of a file based database for easy deployment, and it performs better than SQLite.

Re: SQLite installation on medium trust

Hi Joe, thanks for your answers.

but I have read this
 

MS-SQL CE 4:
(only available in .NET4) mojoportal-x-x-x-x-sqlce-net40-deploymentfiles.zip

SQL CE also works with the Framework3.5 ?

 

Thanks again.

Re: SQLite installation on medium trust

Hi,

The version of SQL CE that mojoPortal is compatible with is CE 4 which requires .NET Framework 4.0 so you can't use .NET 3.5 mojoPortal releases with SQL CE.

HTH,
Joe D.
