| | | | | | | | | | | | | | This makes uses of StringPrintf and friends use the base namespace and include stringprintf.h explicitly. This also removes a bunch of unnecessary string_util includes (which exposed a few other errors like people forgetting to include <vector>.

* Extend Histogram class to support custom range definitionsjar@chromium.org2010-04-291-5/+90
| | | | | | | | | | | | | | | | | | Some users have a small sparsely separated enumerated list of plausible samples which don't fit well into a default (log space) histogarm, or a consistently spaced (LinearHistogram). This implementation does not yet support renderer histograms of this sort, but it at least unblocks the dependent bug that needs support for these sparse histograms in the browser. The bulk of this patch was written by Raman Tenetti, in CL 1706012.

* Cleanup histogram classes mixing SetFlags into FactoryGet argumentsjar@chromium.org2009-12-281-136/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Use factory to create histograms, and refcounts to track lifetimesjar@chromium.org2009-12-061-54/+75
| | | | | | | | | | | | | | | 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
