Welcome to Radio Liferay, a peek into what is going on in Liferay from the people doing it themselves.
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
- an example upgrade path for bookmarks
- 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)
- And an example: The implementation of this API in Journal
- more documentation on registering and checking permissions
- 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 42: Zsigmond Rab on Enterprise Support
At Devcon, I took the opportunity to meet several people - stay tuned for several more episodes during the rest of this year. For this episode, I spoke with Zsigmond Rab. Zsigmond is Lead Engineer, Technical Support & Trainer at Liferay Hungary. This is a short and informal tongue-in-cheek talk about support-related issues.
- The structure of the Hungarian Support teams
- How
bugsunexpected features are handled - How to make sure that these don't show up again in the next version
- Fixpacks, Hotfixes, Servicepacks
- Other worldwide support teams
You might or might not know that Liferay's business is built on Enterprise Edition - and specifically on the support services that we offer here. This is what keeps the new versions coming. This episode is meant to give you some information about the procedures that happen when you (as a customer) file an issue for Liferay support. Compared to the actual internal workflow, this is simplified, but gives sufficient insight. If you want more details, please comment.
