| | | | | | | | | | | | | | | | | | | | | from the block files. Stress testing the cache reveals a problem with the deletion of some data from an entry: it is possible to crash in a way that the block file thinks a block is free and an entry thinks the block is in use. This CL corrects that issue. There is also some new tests and a bunch of DCHECKS added while looking for the problem, as well as adding tests to make sure that a block file is accessed only from one thread (there is no problem with the current code in that regard) BUG=55605 TEST=netunittests Review URL: http://codereview.chromium.org/3430004 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@59711 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | | | | | | | This is CL patch 377028 by Raman Tenneti, with minor changes to make the try-bots happier.

* 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. Review URL: http://codereview.chromium.org/42682 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@12692 0039d316-1c4b-4281-b951-d872f2087c98
* 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.

* 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.
