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 41: The 37000ft overview of staging with Máté Thurzó
Another first: This week's guest Máté Thurzó presents a brief 37000ft overview over Staging. Yes, this is literally 37000ft - we both were lucky to be invited to the North America Symposium 2014 and had the same flight back. Yes, this episode has been recorded 11277m over the atlantic ocean on the flight from Boston to Frankfurt, and it's also a first time that you see me use imperial units voluntarily.
- The problem that staging solves
- "Workflow" for a whole site
- What's new in staging in Liferay 6.2?
- Staging in custom portlets
- sample LAR portlet on github
- Service Builder builds a lot of code required for staging
- my Ridiculously Simple Portlets and Máté's Staging appearance on dev.life, extending those simple portlets
- How LAR import/export relates to staging
- Local vs. Remote Staging
- The new staging UI: Visible Progress, Background processing
- Performance rule of thumbs: "it depends" - I don't give the numbers here. Listen to the conversation to find out what it depends on.
- Staging through multiple stages
- The future of staging (in 7.0, available in the current milestone)
- The effect of customer feedback on the future of staging. Hopefully you gave your feedback at Devcon, where Máté was attending to get more feedback. This episode should have been out by then; sorry, postprocessing took a while longer than anticipated.

Again, shoutout and big thank you to Auphonic for postproduction help. This time I really made them work. If you want to compare the result to the actual recording - let me know and you'll get a snippet of the raw file which they de-noised!
