Server move

  • Web server now up, Confluence/JIRA moved, running latest versions with embedded Tomcats
  • Postgres and data directories are backed up in cron scripts, saving a few days worth and mirrored via sftp
  • Mail coming from for the moment
  • Next steps...


  • IDP-594 Some progress on localStorage
    • Picked up localStorage again. I don't think sub flows are a good idea because the conversation scope is stored in the HTTP session. Don’t really want to deal with input/output attribute mapping. Instead, we'll likely have two view-states, one for reading and optionally one for writing if localStorage is supported, falling back to cookies and the servlet filter for writes if not.

      To transfer the serialized storage service context map between the client (browser) and the server (the IdP storage service) in a view-state, we can use (a) Web Flow/MVC model binding, or we can (b) evaluate an expression in the transition-state of the view-state. The advantage to model binding (a) is less XML, whereas the advantage to evaluating an expression (b) is explicit XML configuration and control.

      It looks like the existing ServletRequestScopedStorageService can be retrofitted to support localStorage. I started that work and have a mock-up. My main concern at this point, as I’ve mentioned previously on the last two dev calls, is changing the scope of the ServletRequestScopedStorageService to session from singleton, and the aop-proxy I think we’ll need, at least to avoid deployers making mistakes when injecting a session scoped bean into a singleton (bean with a longer life).

      My plan is to get the mock-up working, including detection for localStorage support and cookie fallback, then committing that for further work and review.
