* Use factory to create histograms, and refcounts to track lifetimesjar@chromium.org2009-12-061-1/+1
| | | | | | | | | | | | | | | This is CL patch 377028 by Raman Tenneti, with minor changes to make the try-bots happier. It is cleanup that better ensures lifetimes of histograms (making it harder for users to abuse them). bug=16495 (repairs leak induced by the first landing) bug=18840 (should make leaks less possible) tbr=raman.tenneti Review URL: http://codereview.chromium.org/462027 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@33933 0039d316-1c4b-4281-b951-d872f2087c98

* Disk cache: More instrumentation for the cache.rvargas@google.com2009-03-201-0/+9
| | | | | | | | | | | | | | Now we separate data between before and after the cache is full. Also, reduce the rate at which a particular client sends data to be only once a week. The effect is that the histogram data will only have one value per client, and the same client will not be "voting" on more than one version (release) at the same time.

* Disk cache: Instead of saving the cache stats only whenrvargas@google.com2009-03-181-0/+3
| | | | | | | | | | | | the destructor is called, store them each five minutes. From the dev channel, 15% of the runs the disk cache destructor is not called, so the stats are not that reliable without this change.

* New disk cache eviction algorithm (partial implementation).rvargas@google.com2009-03-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Disabled by a #def. When enabled, file format 2.1 is used, with a possible update from ver 2.0. If a version with this code disabled is run after the upgrade, it will just discard the file and go back to 2.0. We now put some of those extra list to use! Entries are separated into various lists depending on how often are used, and we keep track of previously evicted entries. If the new algorithm is not enabled, most of the code just goes through a different path (with the old code instead of the new one). One notable exception is OpenFollowingEntry, used to enumerate the entries on the cache; the code changed significantly to support the new version of the "cache iterator", but functionally should do the same as the current code.

* Use histograms to send interesting parts of the disk cache statistics.rvargas@google.com2008-09-241-4/+12
| | | | | | | | | | | Most of this CL deals with a derived implementation of histograms that just queries the size stats already generated by the disk cache. The exact number of buckets, and their distribution, is controlled directly by the new class and the disk cache stats code.
