* Use C99 standard format macros for 64-bit values.agl@chromium.org2009-06-291-1/+2
| | | | | | | | | | | | | | | | | | | Currently we have several uses of %I64d in format strings to indicate a 64-bit value. This does not work on Mac or Linux, where 'I' indicates the use of locale specific digits. Instead, we introduce base/format_macros.h which mimic the C99 standard macros for 64-bit values in a cross-platform manner. Dean pointed out that V8 is handling this themselves rather than use inttypes.h. Maybe we'll end up going down the same path but, for the moment, we'll try and do it the 'correct' way and see how it works out. http://codereview.chromium.org/147154 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@19500 0039d316-1c4b-4281-b951-d872f2087c98
* Disk Cache: Second pass (and final) to allow multiple instancesrvargas@google.com2009-03-271-6/+15
| | | | | | | | | | | | | | | | | | | of BackendImpl. This cl takes care of all the histograms on the disk cache. Most of them have to be splitted in three so that we get separate data from different cache types. There are a few places where the complexity of splitting the histogram is not worth it so we just keep either all data together (if it makes sense), or just ignore data for some types of caches. note: Having multiple versions of a histogram but only one "active" for a given client is not the same as having multiple histograms working at the same time for different objects.

* Disk cache: More instrumentation for the cache.rvargas@google.com2009-03-201-0/+36
| | | | | | | | | | | | | | 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.com2009-03-181-11/+15
| | | | | | | | | | | | 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.com2008-09-241-0/+33
| | | | | | | | | | | 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.
