From af061d3e9c09baa0df2f2d4724baed06cc6158ca Mon Sep 17 00:00:00 2001 From: Doug Evans Date: Mon, 3 Aug 2015 09:04:03 -0700 Subject: [PATCH] Move basic perf-test output from perftest.log to perftest.sum. This patch does two things. 1) Add support for multiple data points. 2) Move the "report" output from perftest.log to perftest.sum. I want to record the raw data somewhere, and a bit of statistical analysis (standard deviation left for another day), but I also don't want it to clutter up the basic report. This patch takes a cue from gdb.{sum,log} and does the same thing with perftest.{sum,log}. Ultimately, we'll probably want to emit raw data to csv files or some such and then do post-processing passes on that. gdb/testsuite/ChangeLog: * lib/perftest/reporter.py (SUM_FILE_NAME): New global. (LOG_FILE_NAME): New global. (TextReporter.__init__): Initialize self.txt_sum. (TextReporter.report): Add support for multiple data-points. Move report to perftest.sum, put raw data in perftest.log. (TextReporter.start): Open sum and log files. (TextReporter.end): Close sum and log files. * lib/perftest/testresult.py (SingleStatisticTestResult.record): Handle multiple data-points. --- gdb/testsuite/ChangeLog | 12 +++++++ .../gdb.perf/lib/perftest/reporter.py | 35 +++++++++++++++---- .../gdb.perf/lib/perftest/testresult.py | 5 ++- 3 files changed, 44 insertions(+), 8 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index e11260c6a61..3e1ad7b12e8 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,15 @@ +2015-08-03 Doug Evans + + * lib/perftest/reporter.py (SUM_FILE_NAME): New global. + (LOG_FILE_NAME): New global. + (TextReporter.__init__): Initialize self.txt_sum. + (TextReporter.report): Add support for multiple data-points. + Move report to perftest.sum, put raw data in perftest.log. + (TextReporter.start): Open sum and log files. + (TextReporter.end): Close sum and log files. + * lib/perftest/testresult.py (SingleStatisticTestResult.record): Handle + multiple data-points. + 2015-07-31 Pedro Alves * gdb.base/attach-pie-misread.exp: Rename $res to $test_spawn_id. diff --git a/gdb/testsuite/gdb.perf/lib/perftest/reporter.py b/gdb/testsuite/gdb.perf/lib/perftest/reporter.py index 1f9358c3ad6..646051e2252 100644 --- a/gdb/testsuite/gdb.perf/lib/perftest/reporter.py +++ b/gdb/testsuite/gdb.perf/lib/perftest/reporter.py @@ -13,6 +13,15 @@ # You should have received a copy of the GNU General Public License # along with this program.
