* This is a second attempt at submitting this changelist. The original one wasmarkus@chromium.org2009-10-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://codereview.chromium.org/196053 It turns out, since none of our tests abstract time correctly, unittests are very sensitive to subtle changes in timing. This made some of the valgrind tests on Linux fail, and unfortunately, neither my desktop nor the trybots could reproduce the problem reliably. As far as I can tell, all the (design) bugs are in the unittests. The browser is actually fine. Tweaked the code a little more. Will resubmit and carefully monitor the buildbots. Original change description follows: When converting between units of time or data types of different precision, we have to be careful to consistently round in the same direction. Timeout checks usually check if Now() is less or equal to a deadline in order to determine if a timeout has occurred. This correctly handles the case where actual sleep times are equal or longer than requested sleep times. But if we round down when setting the sleep delay, this can result in unnecessary and expensive looping. Make sure, we always round up when converting to a format with less precision.

* - Added support for keeping track of load times.davemoore@chromium.org2009-04-031-0/+6
| | | | | | | | | | | | | | | | | For each document loaded we record the time the page was requested by the user (or as close as we can get to that), the time the load process started, the time the document and it's dependent resources (scripts) have been loaded (before onload()) and the time all the document's resources have been loaded. We use this data for two things: 1) We histogram the deltas between the time marks 2) We expose the times to javascript running on the page which was loaded Review URL: http://codereview.chromium.org/42527 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@13116 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | With GCC, we don't have much hope of inlining unless the defintion is in the header. This should also hopefully allow the compiler to do things like constant folding on the multiplications, etc. Review URL: http://codereview.chromium.org/17802 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@7928 0039d316-1c4b-4281-b951-d872f2087c98
