Pages should watch themselves

[ghost]

Original Title: Too many files open

When there are many files opening because of the rendering of a webpage it throws up this error :

if (err) throw err;
^
Error: EMFILE, Too many open files

When you get a chance can you add what your current kern.maxfiles setting is by running:

sysctl -a | grep files 

Or something similar, also add how many files are in the project you are working on:

ls -1R | grep .*. | wc -l

I have a feeling this is related:

Or I have a really serious bug...

we found the problem in nratan's project and solved it, it will be a problem for others and should be fixed within haiku to prevent head scratching and frustration.

He was looping over about 100 posts that all had exerts with image tags with a src attribute that didn't exist yet, when the browser tried to load these each request went to the haiku server which attempted to reload itself for each image at about the same time causing the "Error: EMFILE, Too many open files" error to occur.

Two things should happen:

1. the main haiku object shouldn't reload itself on every request, each piece of content should be aware of changes to it's file and update itself accordingly using fs.watchFile http://nodejs.org/docs/v0.4.12/api/all.html#fs.watchFile this will greatly reduce the amount of file reads and work that needs to be done to provide the updated content
2. we should keep an eye on the amount of open files and queue file reads in a way that we never hit the kern.maxfiles limit as suggested here: http://groups.google.com/group/nodejs/browse_thread/thread/e4c8ca9430dafc53
