  1. Spitfire Overview Gavin McCance

  2. Outline • Review of 1.something • What’s different in 2.1? • Spitfire Components • Status

  3. What is it? • Lets you use remote relational database (RDBMS) • Over WAN • Uses Grid certificates for authentication • Cool authorization (configurable roles)

  4. What was there before? • Release 1.something • Based on the XSQL servlet from Oracle • Defined a server-side template SQL instruction whose blanks were filled in by the parameter’s from the client’s HTTP request. • SELECT LFN FROM REPCAT WHERE PFN={@pfn}

  5. What was there before? • This filled-in template was executed on the back-end database (e.g. MySQL) and the resultset returned to the client in some suitable format. • Either plain XML • Or piped through a XSL transform to turn it into a nice webpage first.

  6. What happened in-between? • All the cool security bits factored out • Authentication  Trustmanager • Authorization  AuthorizationManager • Jwget  HTTPClient • Repackaging. Immense Spitfire ‘bundle’ unravelled; we don’t ship Java with it now…

  7. New in version 2.something • Current release is 2.1.0 • Went down web-services road • Client API defined for a Remote Procedure Call web service • Based on the major SQL operations that you’d like to run against a relational database plus some others for accessing the database meta-data

  8. Three APIs defined • SpitfireBase (~DML stuff) • Insert, Update, Delete, Select • SpitfireAdmin (~DDL stuff) • Create, Drop, Modify(alter) • SpitfireInfo (basic meta-data) • ShowTables, Show ColumnTypes

  9. Web Service Implementation • Same as replica web services • Apache Axis • Running inside Tomcat • Exposing the API in a standard WSDL format • Client API libraries auto-generated from the WSDL • Java JAR and gSOAP C++ static library

  10. Components (available as RPMs) • The previous version (XSQL) retained as edg-spitfire-browser • Web services version packaged as edg-spitfire-server • Common configuration of browser + server for EDG environment edg-spitfire-config • Clients packaged as edg-spitfire-client-java and edg-spitfire-client-c++

  11. edg-spitfire-server + client RDBMS Axis RPCHandler Spitfire Server Trustmanager WAN SOAPHandler Authorization Manager Spitfire Axis Client App Servlet engine

  12. edg-spitfire-browser RDBMS XSQL Servlet Trustmanager WAN AuthzServlet Authorization Manager Web Browser Servlet engine

  13. Status • v2.1.0 of server + java client made available end of January • v2.1.0 of browser available very soon • v2.1.0 of C++ client available very soon • Documentation is still a bit rough…

  14. In CVS • ‘edg-spitfire-server’ • ‘ant release’ will build • ‘edg-spitfire-server’ RPM + tarball • ‘edg-spitfire-config’ RPM + tarball • ‘edg-spitfire-java-client’ RPM + tarball • ‘edg-spitfire-client’ • ‘ant release’ will build • ‘edg-spitfire-client-c++’ RPM + tarball • Any others we might like

  15. In CVS • ‘edg-spitfire-browser’ • ‘ant release’ will build • ‘edg-spitfire-browser’ RPM + tarball • ‘spitfire’ and ‘edg-spitfire-interface’ are dead modules
