[RFC PATCH v7 0/9] gitweb: Output caching, with eval/die based error handling

From: Jakub Narebski <jnareb@gmail.com>

Message-ID: <20101222234843.7998.87068.stgit@localhost.localdomain>

This is preliminary (proof of concept) version of shortened series intended as replacement (rewrite) of "Gitweb caching v8" series from John 'Warthog9' Hawley (J.H.).

This series shows how one can manage exception handling using die_error like die, even in the presence of output caching. The output caching engine has an option that allows to turn off (default) or on caching of error pages.

This series is unfinished; it does not include adaptive cache lifetime, nor support for other caching engines than the one provided (like Cache::Cache or CHI), nor does it support background cache generation or progress info indicator.

This is just intended as proof of concept.

Jakub Narebski (9):
      gitweb: Add optional output caching
      gitweb/lib - Cache captured output (using compute_fh)
      gitweb/lib - Very simple file based cache
      gitweb/lib - Simple output capture by redirecting STDOUT to file
      t/test-lib.sh: Export also GIT_BUILD_DIR in test_external
      gitweb: Prepare for splitting gitweb
      gitweb: Introduce %actions_info, gathering information about actions
      gitweb: use eval + die for error (exception) handling
      gitweb: Go to DONE_REQUEST rather than DONE_GITWEB in die_error
