Re: [Wikitech-l] Update on single-revision deletion

[fl]

I would also be interested in the current status of the request.

As many may already be aware, policy has been in place for the 
function's use on en.wp since late November 2009. I for one am very 
eager to have this function deployed, if not on all WMF wikis, to en at 
least.

Speeding up parsing will reveal a new bottleneck for the devs to fight
the enwiki community over, don't worry about that.

So I saw from Domas's followup :-)

Nevertheless - a process isn't the same process when it's going at 10x
the speed. This'll be interesting.

(I'm sure the complexity of templates will go up to compensate, unless
Tim's parser functions reaper is set down to match, muwahaha.)

You're comparing apples with oranges. Domas was testing a simple API
page info query, which is much more lightweight than a full-blown
parse involving enwiki's crazy templates.

Lots. I'm trying to get basic functionality/prototypes work.
Some changes had to be done to HipHop itself, some had to be done to generated 
code, some had to be done to MediaWiki. 

MediaWiki's "run wherever I can" dynamic adaptation to any environment isn't 
too helpful sometimes...

The parser typically takes 2-10 seconds on an uncached en:wp page, so
speeding that process up 1000x is, um, HOLY CRAP!

(Hosting providers sell network bandwidth and disk space; I can see
them putting resources into Hiphopifying the common PHP crapware just
to use 1/1000 the CPU.)

Domas, how much hacking did you have to do to MediaWiki to get it to
compile in Hiphop?
