* Cleanup histogram classes mixing SetFlags into FactoryGet argumentsjar@chromium.org2009-12-281-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Generic cleanup of histogram class, renaming *FactoryGet to FactoryGet, along with reformatting. The macros were cleaned up to use common sub-macros rather than repeating code as much. Removed ThreadSafeHistogram (and associated ASSET_HISTOGRAM macros) since this class was not getting used. I introduced UMA_HISTOGRAM_ENUMERATION to support the common use of LinearHistograms to count various enumerated values. I added a Flags argument to all the FactoryGet routines to help avoid needing to call SetFlags each time a new sample is Add()ed. This also simplifies the code. This will all help prepare for a "don't histogram at all" macro setting so that I can test the impact of the histogram macro calls on performance (since there are now so many active histograms).

* Fixing bugs in sparse cache when dealing with GetAvailableRange queries not ↵hclam@chromium.org2009-09-022-5/+24
| | | | | | | | | | | | | | | | | aligned TEST=net_unittests --gtest_filter=DiskCacheEntryTest.PartialSparseEntry In handling GetAvailableRange() queries, if the start offset is not aligned to 1KB, there was some strange behaviors: 1. The start offset found is smaller than the input offset 2. Number of continus bytes doesn't take into account offset in a block. This patch will fix the above problems.

| | | | | | | | | | | | | | | TEST=net_unittests --gtest_filter=DiskCacheEntryTest::PArtialSparseEntry If we do a partial write with the following criteria, disk_cache::SparseControl will crash: 1. first_byte and last_byte in the same 1KB block 2. first_byte % 1024 != 0 3. (first_byte >> 10) % 32 == 31 Review URL: http://codereview.chromium.org/176067 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@25134 0039d316-1c4b-4281-b951-d872f2087c98
