Revert "pack: packfile_free -> git_packfile_free and use it in the indexers" 2013-01-11T19:17:21+00:00 Carlos Martín Nieto cmn@dwim.me 2013-01-11T19:15:06+00:00 80d647adc31e3c8721dc578140494f916463f623 This reverts commit f289f886cb81bb570bed747053d5ebf8aba6bef7, which makes the tests fail on Windows.

Currently limited to 16MB (like git) and to objects up to 1MB in
size.

Many delta bases are re-used. Cache them to avoid inflating the same
data repeatedly.

This version doesn't limit the amount of entries to store, so it can
end up using a considerable amound of memory.

To paraphrase @peff:

You can get both size and type from a packed object reasonably cheaply.
If you have:

* An object that is not a delta; both type and size are available in the
  packfile header.
* An object that is a delta. The packfile type will be OBJ_*_DELTA, and
  you have to resolve back to the base to find the real type. That means
  potentially a lot of packfile index lookups, but each one is
  relatively cheap. For the size, you inflate the first few bytes of the
  delta, whose header will tell you the resulting size of applying the
  delta to the base.

For simplicity, we just decompress the whole delta for now.
