SCons Timings

From 159815ad9df69136ff8be2c0cf6bda8794151fc5 Mon Sep 17 00:00:00 2001 From: stevenknight Date: Fri, 18 Dec 2009 08:03:50 +0000 Subject: [PATCH] Move the timings-specific pieces of the buildbot infrastructure into the trunk/timings directory. We'll map them into the buildbot directory using svn:externals. This will let us keep all the pieces of a timing configuration, including its buildbot pieces, in one place, and will let us simplify the Master initialization (since it will be able to look on-disk for the configurations for which it should set up buildbot steps, instead of querying the SVN server). git-svn-id: http://scons.tigris.org/svn/scons/trunk@4562 fdb21ef1-2011-0410-befe-b5e4ea1792b1 --- timings/changelog.html | 204 +++++++++++++++++++ timings/graph.html | 411 ++++++++++++++++++++++++++++++++++++++ timings/index.html | 196 ++++++++++++++++++ timings/js/common.js | 96 +++++++++ timings/js/coordinates.js | 125 ++++++++++++ timings/js/plotter.js | 336 +++++++++++++++++++++++++++++++ 6 files changed, 1368 insertions(+) create mode 100644 timings/changelog.html create mode 100644 timings/graph.html create mode 100644 timings/index.html create mode 100644 timings/js/common.js create mode 100644 timings/js/coordinates.js create mode 100644 timings/js/plotter.js diff --git a/timings/changelog.html b/timings/changelog.html new file mode 100644 index 00000000..586ebadc --- /dev/null +++ b/timings/changelog.html @@ -0,0 +1,204 @@ + + + + + + + + + + + + diff --git a/timings/graph.html b/timings/graph.html new file mode 100644 index 00000000..e418069d --- /dev/null +++ b/timings/graph.html @@ -0,0 +1,411 @@ + + + + + + + + + + + + + + + + + +

+Builds generated by the buildbot +are run through + +and the results of that test are charted here. +

+ +

+The vertical axis is measured values, and the horizontal +axis is the revision number for the build being tested. +
