Radio Liferay Episode 60: Performance and Permissions with Preston Crary

  An episode on the "Per" things: Performance and Permissions. I spoke to Preston Crary, who amazingly was not mad at me for losing an earlier recording.

We're talking about these (and more) topics

  • We open with the attention to detail that's required for working on performance tuning and some short conversation about this topic.
  • Sadly, there's not often a single silver bullet, but many areas of dust.
  • Sometimes the fastest code is not the most optimal
  • Continuing with Preston's work on Permissions:
  • ResourceBlock is deprecated, and there's an easy migration path
  • The usecase for Resources, ResourcePermission, and ResourceBlocks (as they're not at all visible on the UI)
  • Preston's way through Liferay from Support to working on the topics that he's now working on
  • The new API for Permissions - and the documentation is also done already (as of me writing this article, not yet published, but available on github - should be a matter of days or hours)
  • Should you implement your own permission system? (and how the answer to this question might change in 7.1)
  • Upgrades are being performance tuned. I smell a future episode coming up. Paging the team that is working on this area
  • The remarkable memory savings that refactoring the UserBag introduced
  • What happend during login
  • Passwords are PBKDF2WithHmacSHA1/160/128000 hashed, a deliberately expensive password hashing algorithm.
  • LPS-75747 and an update to my hardball question: Document Library's default.xml is still in core, can't be updated through a module, just through an ext.

Radio Liferay Episode 44: Stian Sigvartsen on Social Apps Proxy

  This is my conversation with Stian Sigvartsen, winner of the Marketplace App contest with his Social Apps Proxy (Link) and well known member of the UK Liferay usergroup, working in Devon and quite a lot with Liferay. Our paths cross quite often, but we finally found some time to talk about Stian's award winning app which basically takes all the boring stuff out of OAuth integrations into Liferay

He did a great job of explaining the background and solution in audio. Here's what we talked about:

  • Social Apps Proxy enables you to integrate content from other social networks into your portal.
  • It's working through OAuth, basically taking over all of the dirty work of authentication, leaving the actual integration works for the implementor
  • Stian's sample app on github (Link): Getting twitter mentions with 10 lines of code
  • What problem does OAuth solve? Comparing OAuth with a Valet Key.
  • Linking Liferay's identity to twitter's (in this sample)
  • How the social apps proxy works: An application just uses it as HTTP proxy, does not care about identity and is happy to get the identity automagically taken care of
  • Social Apps Proxy on Marketplace
  • Supported Versions of Liferay 6.1 to 6.2 and OAuth 1.0a to 2 to be extended
  • Microservices
  • All Code is to be open sourced soon, contributors are welcome.
