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 57: Jim Hinkey and Cody Hoag on documentation

  Today I'm welcoming a repeat guest and a new one: Jim Hinkey (of episode 21 fame) and Cody Hoag - both from Liferay's documentation and knowledge management team. This episode has unfortunately suffered from various disturbances in the space-time-continuum: I had it sitting on my disk for quite a while. The Javadoc Contest that we've "started" in this episode was actually published/announced in the meantime and unfortunately ended recently. Congratulations to Sébastien and Marcellus. However, not to render the call for action in this episode useless, let's start another one soon - there can't be enough Javadoc, and I admit that we have still plenty of opportunities to write new documentation left for you. Please subscribe to the comments on Cody's winner's announcements to see the update - I'll also mention it on a Radio Liferay episode once it's been restarted. But I'll also put a word in for you if you already write the javadoc now.

In this episode we're talking about these (and more) topics

  • glimpse of history - remembering episode 21 with Jim
  • Javadoc coverage went up from then on
  • Javadoc metrics tool by Cody
  • Javadoc contribution process: Send to liferay user repo, tag Cody @codyhoag
  • Javadoc guidelines on dev.liferay.com (two flavors - basic and advanced guidelines)
  • Submitting Unit Tests together with Javadoc
  • The new home for documentation, dev.liferay.com
  • "Edit on github" available for documentation. Use it - it's easy.
  • Documentation: Javadoc, Taglibraries and other duties of the team.
    (mention Mike Williams on taglib pullrequests)
  • docs.liferay.com and its content
    blade repository (in the meantime moved from Ray's to Liferay's repository)
  • BREAKING_CHANGES.markdown
  • Migration Tutorials (WAR->7.0->modules) on dev.liferay.com
  • "blade migrate" is (at least temporarily) out??? (summoning Greg)
  • the current Javadoc Contest and a cheesy mentioning of 2015's internal javadoc contest) (#2 Igor Beslic, #1 Moi)
    • (and some hints on how to dominate a javadoc contest)
