This will collect -information on the execution time of a Perl script and of the subs in that -script. This information can be used to determine which subroutines are -using the most time and which subroutines are being called most often. This -information can also be used to create an execution graph of the script, -showing subroutine relationships. - -To profile a Perl script run the perl interpreter with the B<-d> debugging -switch. The profiler uses the debugging hooks. So to profile script -F<test.pl> the following command should be used: - - perl5 -d:DProf test.pl - -When the script terminates (or when the output buffer is filled) the -profiler will dump the profile information to a file called -F<tmon.out>. A tool like I<dprofpp> can be used to interpret the -information which is in that profile. The following command will -print the top 15 subroutines which used the most time: - - dprofpp - -To print an execution graph of the subroutines in the script use the -following command: - - dprofpp -T - -Consult L<dprofpp> for other options. - -=head1 PROFILE FORMAT - -The old profile is a text file which looks like this: - - #fOrTyTwO - $hz=100; - $XS_VERSION='DProf 19970606'; - # All values are given in HZ - $rrun_utime=2; $rrun_stime=0; $rrun_rtime=7 - PART2 - + 26 28 566822884 DynaLoader::import - - 26 28 566822884 DynaLoader::import - + 27 28 566822885 main::bar - - 27 28 566822886 main::bar - + 27 28 566822886 main::baz - + 27 28 566822887 main::bar - - 27 28 566822888 main::bar - [....] - -The first line is the magic number. The second line is the hertz value, or -clock ticks, of the machine where the profile was collected. The third line -is the name and version identifier of the tool which created the profile. -The fourth line is a comment. The fifth line contains three variables -holding the user time, system time, and realtime of the process while it was -being profiled. The sixth line indicates the beginning of the sub -entry/exit profile section. - -The columns in B<PART2> are: - - sub entry(+)/exit(-) mark - app's user time at sub entry/exit mark, in ticks - app's system time at sub entry/exit mark, in ticks - app's realtime at sub entry/exit mark, in ticks - fully-qualified sub name, when possible - -With newer perls another format is used, which may look like this: - - #fOrTyTwO - $hz=10000; - $XS_VERSION='DProf 19971213'; - # All values are given in HZ - $over_utime=5917; $over_stime=0; $over_rtime=5917; - $over_tests=10000; - $rrun_utime=1284; $rrun_stime=0; $rrun_rtime=1284; - $total_marks=6; - - PART2 - @ 406 0 406 - & 2 main bar - + 2 - @ 456 0 456 - - 2 - @ 1 0 1 - & 3 main baz - + 3 - @ 141 0 141 - + 2 - @ 141 0 141 - - 2 - @ 1 0 1 - & 4 main foo - + 4 - @ 142 0 142 - + & Devel::DProf::write - @ 5 0 5 - - & Devel::DProf::write - -(with high value of $ENV{PERL_DPROF_TICKS}). - -New C<$over_*> values show the measured overhead of making $over_tests -calls to the profiler These values are used by the profiler to -subtract the overhead from the runtimes. - -The lines starting with C<@> mark time passed from the previous C<@> -line. The lines starting with C<&> introduce new subroutine I<id> and -show the package and the subroutine name of this id. Lines starting -with C<+>, C<-> and C<*> mark entering and exit of subroutines by -I<id>s, and C<goto &subr>. - -The I<old-style> C<+>- and C<->-lines are used to mark the overhead -related to writing to profiler-output file. - -=head1 AUTOLOAD - -When Devel::DProf finds a call to an C<&AUTOLOAD> subroutine it looks at the -C<$AUTOLOAD> variable to find the real name of the sub being called. See -L<perlsub/"Autoloading">. - -=head1 ENVIRONMENT - -C<PERL_DPROF_BUFFER> sets size of output buffer in words. Defaults to 2**14. - -C<PERL_DPROF_TICKS> sets number of ticks per second on some systems where -a replacement for times() is used. Defaults to the value of C<HZ> macro. - -C<PERL_DPROF_OUT_FILE_NAME> sets the name of the output file. If not set, -defaults to tmon.out. - -=head1 BUGS - -Builtin functions cannot be measured by Devel::DProf. - -With a newer Perl DProf relies on the fact that the numeric slot of -$DB::sub contains an address of a subroutine. Excessive manipulation -of this variable may overwrite this slot, as in - - $DB::sub = 'current_sub'; - ... - $addr = $DB::sub + 0; - -will set this numeric slot to numeric value of the string -C<current_sub>, i.e., to C<0>. This will cause a segfault on the exit -from this subroutine. Note that the first assignment above does not -change the numeric slot (it will I<mark> it as invalid, but will not -write over it). - -Mail bug reports and feature requests to the perl5-porters mailing list at -F<E<lt>perl5-porters@perl.orgE<gt>>. - -=head1 SEE ALSO - -L<perl>, L<dprofpp>, times(2) - -=cut - -# This sub is needed for calibration. -package Devel::DProf; - -sub NONESUCH_noxs { - return $Devel::DProf::VERSION; -} - -package DB; - -# -# As of perl5.003_20, &DB::sub stub is not needed (some versions -# even had problems if stub was redefined with XS version). -# - -# disable DB single-stepping -BEGIN { $single = 0; } - -# This sub is needed during startup. -sub DB { -# print "nonXS DBDB\n"; -} - -use XSLoader (); - -# Underscore to allow older Perls to access older version from CPAN -$Devel::DProf::VERSION = '20000000.00_00'; # this version not authorized by - # Dean Roehrich.
