* Disk Cache: Delete chained block files when they become empty.rvargas@google.com2009-07-281-16/+62
| | | | | | | | | | | | | | | We were leaving empty block files in the chain, and worst of all, not reusing them because we were thinking that these files were "almost full". Now we also check for empty files when the cache starts. BUG=16740 TEST=unittest.

* Disk cache: Add explicit support for eviction / deletionrvargas@google.com2009-07-091-1/+4
| | | | | | | | | | | | | | | | | | | | | | | of sparse entries. I started to add code to modify the children_map of the parent entry when a child is evicted but that ended up being too much trouble for too little gain. We have to be prepared to handle the case of not finding a child entry because there is no way to make sure that the process doesn't go away at any time, so adding a lot of complexity just to avoid an extra entry lookup is just not worth it. On the other hand, potentially freeing up a lot of space when a sparse entry is deleted (insetad of just waiting for the eviction code to do the cleanup) seems like a good thing.

* Fix Linux buildbot breakage on BlockFiles_Grow due to lingering cache files.mmoss@google.com2008-09-091-4/+5
| | | | | | | | | | | | | | The buildbot was breaking because temporary cache files were being created under /tmp, like "/tmp/cache_test\data_*", rather than under /tmp/cache_test, like "/tmp/cache_test/data_*". This prevented the files from being cleaned up when /tmp/cache_test was deleted, and after a few runs, the max of 256 cache files was reached, and the tests failed when they couldn't create more. The following changes were made: - Replace '\' with platform-dependent path separator in various places. - Define constant (same as Windows) for invalid Linux file handle to fix error where wrong value was tested. - Force cache initialization in block_files tests, otherwise it fails to create cache files after calling DeleteCache().
