      mod_cache: Add a discrete commit_entity() provider function within the · 4fff6fbd
      Graham Leggett authored 
      mod_cache provider interface which is called to indicate to the
provider that caching is complete, giving the provider the opportunity
to commit temporary files permanently to the cache in an atomic
fashion. Move all "rename" functionality of temporary files to permanent
files within mod_disk_cache from ad hoc locations in the code to the
commit_entity() function. Instead of reusing the same variables for
temporary file handling in mod_disk_cache, introduce separate discrete
structures for each of the three cache file types, the headers file,
vary file and data file, so that the atomic rename of all three file
types within commit_entity() becomes possible. Replace the inconsistent
use of error cleanups with a formal set of pool cleanups attached to
a subpool, which is destroyed on error.

      mod_cache: Change the signature of the store_body() provider function · 4470d41d
      Graham Leggett authored 
      within the mod_cache provider interface to support an "in" brigade
and an "out" brigade instead of just a single input brigade. This
gives a cache provider the option to consume only part of the brigade
passed to it, rather than the whole brigade as was required before.
This fixes an out of memory and a request timeout condition that would
occur when the original document was a large file. Update the
mod_disk_cache provider implementation to take into account the new API.
Introduce CacheReadSize and CacheReadTime directives to mod_disk_cache
to control the amount of data to attempt to cache before sending the
data on to the client in the "out" brigade.
