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 32: Jack Rider

 This week's guest is Jack Rider, from the mediterrean shore in Benidorm. He is a real Liferay veteran, having started with version 3.6, and has initiated quite a few very nice and well-usable projects.

Here are our topics:

  • Jack started in 2005 with Liferay 3.6, got first trained on Liferay 4.2 in 2007
  • He's working as a freelancer, specializing in Liferay, BPM and their integration
  • xmlportletfactory. This project generates simple CRUD portlets that make use of servicebuilder and many other aspects of the Liferay infrastructure. With many contributions from its community (e.g. Juan) more and more of the infrastructure is used: ServiceBuilder, Asset Framework, Workflow, IPC, Entity Relationships, Export to Excel, Activities,
  • xmlportletfactory is a one-time codegenerator: You generate once, then you can modify the resulting code.
  • The code is generated from templates - as it's open source (GPL3), of course you can change it.
  • Jack is also currently integrating BonitaBPM into Liferay. This replaces the Bonita Portal, you can interact with the Workflow engine from Liferay as well as from an  Android smartphone. This integration is expected to show up on the marketplace soon. It now has been published on marketplace.
  • As we speak about publication on the marketplace, let me insert a short&shameless pointer to my own fabulous podcasting app. It was not out when we recorded the podcast, but now it is.
  • bonitalife.org
  • Bonita being recognized by Gartner as the only open-source product that meets Gartner's definition of a BPMS.
  • Jack has another site, portlet.es - providing some sample portlets: A Sudoku generator (maybe it appears on marketplace soon), a Lexicon filter (e.g. for forums, blocking keywords), GroupNotification (find marketplace link) - (sends emails to all usergroups or site members)
