66499 - RFE on jprof: pause, resume, rewind

Status: RESOLVED FIXED

(SeaMonkey :: General, defect)

Description

[(not reading, please use [e-mail] instead)]

more details to follow soon.

this would be a great feature for jprof.  I'll do some thinking about it, and cc
jlance to see what he thinks.

assigning to mcafee for now, as he's a linux hacker and may have time to help
get this going.

thanks to dbaron, jprof does have pause.

here's how I'm using jprof to profile a particular action:

in your ~/.cshrc, do this:

setenv JPROF_FLAGS JP_DEFER

That makes it so you don't start profiling until it gets the SIGPROF signal.

# run mozilla, and get ready to do your stuff...
./mozilla

# start profiling...
kill -PROF {mozilla-bin pid}

# do your stuff...

# pause profiling...
kill -USR1 {mozilla-bin pid}

# exit mozilla

./jprof ./mozilla-bin jprof-log > jprof.html

I will leave this in as a reminder to add some docs to
the jprof page.  Off the new-bug radar.
