Declared ETags, together with Russian Doll caching, can be used to automatically mix your template and asset versions into the ETags set in your controllers. This avoids the need to blow all browser caches on each deploy and neatly contains the scope of "freshness fallout" when you tweak a view.

To include the template's version in the ETag:

  # Incorporate the cache version for this action into our ETag.
  # This allows template changes to bubble up into HTTP cache
  # freshness and bust browser caches when we make changes.
  etag do
    begin

Changes:

• this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

  ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

• this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

  This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.

Why is the server unhappy?

• Bundle API is 70%-80% of traffic and it has to resolve the dependency graph and Marshal
• x Processes are spinning in Ruby with 380% (of 400% total CPU [4 x 100%])
• x Bundle can only use vanilla gems, so that's why we have to use Marshal
• Redis Heapsize
• Diskspace

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)
