perf perl scripts: Fix SIGALRM and pipe read race for rwtop

2013-02-06T21:09:27Z

Fixing rwtop script race. The issue is caused by rwtop script triggering SIGALRM and underneath pipe reading layer reporting error when interrupted. Fixing this by setting SA_RESTART for rwtop SIGALRM handler, which avoids interruption of the pipe reading layer.

perf script: Remove workqueue-stats script

2013-01-24T19:40:53Z

The tracepoints used by the workqueue-stats script no longer exist so trying to run the script results in: # perf script record workqueue-stats invalid or unsupported event: 'workqueue:workqueue_creation' Run 'perf list' for a list of valid events So remove the script until it can be reworked using the new workqueue tracepoints.

perf/trace/scripting: rwtop script cleanup

2010-05-10T22:50:56Z

A couple of fixes for the rwtop script: - printing the totals and clearing the hashes in the signal handler eventually leads to various random and serious problems when running the rwtop script continuously. Moving the print_totals() calls to the event handlers solves that problem, and the event handlers are invoked frequently enough that it doesn't affect the timeliness of the output. - Fix nuisance 'use of uninitialized value' warnings Cc: Frédéric Weisbecker Cc: Ingo Molnar Message-Id: <1273466820-9330-4-git-send-email-tzanussi@gmail.com> Signed-off-by: Tom Zanussi Signed-off-by: Arnaldo Carvalho de Melo
