Re: Why does phpBB end documents with ?> ?

This codicil is really for other browsing readers rather than the posters above who will be familiar with this. This isn't a widely discussed feature or issue of PHP. The only reference that I can find in the php.net manual is in the section Language Reference->Basic Syntax-> Instruction separation ...

Re: Administration of Language Packs

Thanks, I've just upgraded all my forums to 3.0.5, with an average downtime of 2 secs each, so I didn't even bother to schedule it. I keep VMs shadows for the different that help run one for support issues, one for dev and one for upgrade reheasals. The cutover of the live forums was done by an inte...

Re: Administration of Language Packs

Humm, we could have quite an interesting discussion. I am well used to using control systems such as svn for controlling developments. However, this is one case where I actually don't think that it's a good fit. The main reason is that the language packs need to bind to a metadata model that is embe...

Re: Extending the scope of the phpBB cache

I know, but there were still hundreds of cache files. ;) We (Chris and i) analysed the usage at phpbb.com and then decided to drop it based on these results. If we think in terms of shared service = acm_files + low transaction rates versus virtual/dedicated service = acm_memory + high transaction r...

Re: Extending the scope of the phpBB cache

Nils, We don't want to falling into the same trap as the benchmarkers. Improving modularisation and autoload could enhance performance for the top 5% or so of installs -- the high volume boards running on dedicated/virtual host services, but it might do this whilst making things worse for the other ...

Re: Extending the scope of the phpBB cache

@Kevin. What TTL did you use? This would only have any advantage on the higher volume boards such as http://www.phpBB.com/community, where a 2 min TTL would save this, so this should only be cached if a memory cache is being implemented (I've posted separately on the simplification of the coherence ...

Re: Very long running query (600ms): could be security issue

to trigger this query, you should have a forum that uses approval Unfortunately not true as it is executed on any forum where a user views a topic using a post reference. Even though the query is a join it is functionally the same as SELECT COUNT(post_time) AS prev_posts FROM phpbb_en_posts WHERE p...

Re: Extending the scope of the phpBB cache

David, The problem is not with the caching of the data itself but with the cache invalidation... Agreed that the coherency issue is always there to bite you. However, we have three broad categories of information in the phpBB system and they have different sweet spots and therefore caching approache...

Re: Extending the scope of the phpBB cache

I've been sucking my teeth on this one. The problem with an "idea" is that it is very hard to "kick the tyres". What I was thinking of doing was a concept demonstrator based on 3.0.5 which wouldn't be a production quality refactoring but might have hacky fringes to minimize the a...
