* Cleanup histogram classes mixing SetFlags into FactoryGet argumentsjar@chromium.org2009-12-281-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Add some diagnostic test to diagnostic modecpu@chromium.org2009-12-205-48/+266
| | | | | | | | | | | | | | | - Move the one existing test to final location - Test more critical paths to be accessilbe and writable - Test the OS version - Test user or systemwide install type BUG=27885 TEST=unit test updated Review URL: http://codereview.chromium.org/504028 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@35057 0039d316-1c4b-4281-b951-d872f2087c98
* Use factory to create histograms, and refcounts to track lifetimesjar@chromium.org2009-12-061-3/+5
| | | | | | | | | | | | | | | 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
