* Create a more fine grained histogram of SDCH payload sizesjar@chromium.org2009-06-291-0/+16

* Get correct request to finsh time for histogramjar@chromium.org2009-06-201-2/+18
| | | | | | | | | | | | | | | Corrected a typo in generating the stat, and evolved to a new histogram name to avoid confusion. Note that the time between start and finish still needs to be fixed, as that part of the regression is not handled. BUG=14678 r=davemoore Review URL: http://codereview.chromium.org/132072 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@18896 0039d316-1c4b-4281-b951-d872f2087c98
* Automatically adapt to faster/slower uploads of renderer histogramsjar@chromium.org2009-05-281-3/+1
| | | | | | | | | | | | | | | | | | | | | This replaces the current time based approach (chrome is given N seconds to upload all renederer histograms) with an asynch callback approach that waits until all renderers have responded (with their updates). It uses a fall-back timer to ensure that a hung renderer won't delay things forever as well. This causes faster (and complete) updates in about:histograms as well as generally assuring complete updates during UMA gatherings. This code was contributed by Raman Tenneti in CL 42496 http://codereview.chromium.org/42496 bug=12850 r=raman Review URL: http://codereview.chromium.org/113473 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@17123 0039d316-1c4b-4281-b951-d872f2087c98
* Remove histogram connection to base classes in stats_counterjar@chromium.org2009-04-101-6/+9
| | | | | | | | | | | | | | | | Now that histograms move data from renderer to browser, there is less reason to connect to stats counters. Stats counters were using shared memory, and now they may plausibly use the histogram's IPC mechanism instead to move data to the browser. The first step is remove the inheritance, and teh next (plausible/future) step would be to implement counters as histograms with only one bucket. r=mbelshe Review URL: http://codereview.chromium.org/66029 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@13544 0039d316-1c4b-4281-b951-d872f2087c98

* wtc: please look at URL related code, and hooks and nitsjar@chromium.org2009-03-131-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | you might have commented on before. huanr: please look at sdch_filter code. The intent was no semantic change, and only change in histograms and stats gathered. I wanted to be sure I had better stats on several failure cases, as the turn-around time of adding stats to instrument such cases after they surface is just too long. The big feature is the mechanism for getting the total number of bytes passed to a filter. We use the filter context to achieve this, and then the SDCH filter can calculate compression ratio (from pre-gunzip vs post SDCH decompress). The number of bytes read was also histogrammed in a number of error scenarios, to better diagnose what is going on when these cases arrise (example: When some data is still buffered in the VCDIFF decoder). The sdch_filter destructor was getting long and hard to read with multiple if blocks, so I cleaned that up as well a bit (less indentation, and use of early returns). Nits not included in previous CL that earlier are listed as well. r=wtc,huanr Review URL: http://codereview.chromium.org/40319 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@11665 0039d316-1c4b-4281-b951-d872f2087c98

* Use histograms to send interesting parts of the disk cache statistics.rvargas@google.com2008-09-241-3/+4
| | | | | | | | | | | 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.

* Define MessagePumpDefault and use it to implement MessageLoop on non-Windowsdarin@google.com2008-08-191-1/+2
| | | | | | | | | | | | | | | | | platforms. This is actually just a first-step toward the real fix which is to use MessagePumpDefault on all platforms on non-UI and non-IO threads. This CL also fixes some GCC compilation errors. I renamed MessageLoopOwnable to TaskBase, which seems more appropriate since a MessageLoopOwnable has a next Task pointer and clearly is only meaningful in the context of Task. (I wonder why it is even a separate class, but that is another issue.) I had to make the next_task / set_next_task methods public since they are used by an inner class of MessageLoop. Perhaps those inner classes should be made into top-level classes, but that seemed like too much to change at this time.
