+
+ Ilya Zakharevich:
+ Newer perls: Add PERL_POLLUTE and dTHR.
+
+1998 Nov 10
+This version of DProf should work with older Perls too, but to get
+full benefits some patches to 5.004_55 are needed. Patches take effect
+after new version of Perl is installed, and DProf recompiled.
+
+Without these patches the overhead of DProf is too big, thus the statistic
+may be very skewed.
+
+Oct 98:
+ Ilya Zakharevich:
+ DProf.xs
+ - correct defstash to PL_defstash
+ - nonlocal exits work
+ dprofpp
+ - nonlocal exits work
+ DProf.pm
+ - documentation updated
+ t/test6.*
+ - added
+
+Nov-Dec 97:
+ Jason E. Holt and Ilya Zakharevich:
+ DProf.xs
+ - will not wait until completion to write the output, size of buffer
+ regulated by PERL_DPROF_BUFFER, default 2**14 words;
+
+ Ilya Zakharevich:
+ dprofpp
+ - smarter in fixing garbled profiles;
+ - subtracts DProf output overhead, and suggested profiler overhead;
+ - new options -A, -R, -g subroutine, -S;
+ - handles 'goto' too;
+ DProf.xs
+ - 7x denser output (time separated from name, ids for subs);
+ - outputs report-write overhead;
+ - optional higher-resolution (currently OS/2 only, cannot grok VMS code);
+ - outputs suggested profiler overhead;
+ - handles 'goto' too;
+ - handles PERL_DPROF_TICKS (on OS/2, VMS may be easily modified too)
+
+Jun 14, 97 andreas koenig adds the compatibility notes to the README
+and lets the Makefile.PL die on $] < 5.004.
+
+Jun 06, 97 andreas koenig applies a patch by gurusamy sarathy because
+Dean is not available for comments at that time. The patch is available
+from CPAN in the authors/id/GSAR directory for inspection.
+
+Sep 30, 96 dmr
+ DProf.xs
+ - added Ilya's patches to fix "&bar as &bar(@_)" bug. This also fixes
+ the coredumps people have seen when using this with 5.003+.
+ DProf.pm
+ - updated manpage
+ t/bug.t
+ - moved to test5
+ Makefile.PL
+ - remove special case for bug.t
+
+Jun 26, 96 dmr
+ dprofpp.PL
+ - smarter r.e. to find VERSION in Makefile (for MM5.27).
+ DProf.pm
+ - updated manpage
+ DProf.xs
+ - keep pid of profiled process, if process forks then only the
+ parent is profiled. Added test4 for this.
+
+Mar 2, 96 dmr
+ README
+ - updated
+ dprofpp
+ - updated manpage, point to DProf for raw profile description.
+ DProf.pm
+ - update manpage, update raw profile description with XS_VERSION.
+ - update manpage for AUTOLOAD changes.
+ DProf.xs
+ - smart handling of &AUTOLOAD--looks in $AUTOLOAD for the sub name.
+ this fixes one problem with corrupt profiles.
+
+Feb 5, 96 dmr
+ dprofpp
+ - updated manpage
+ - added -E/-I for exclusive/inclusive times
+ - added DPROFPP_OPTS -- lazily
+ - added -p/-Q for profile-then-analyze
+ - added version check
+ dprofpp.PL
+ - pull dprofpp's version id from the makefile
+ DProf.pm
+ - added version to bootstrap
+ - updated doc
+ - updated doc, DProf and -w are now friendly to each other
+ DProf.xs
+ - using savepv
+ - added Tim's patch to check for DBsub, avoids -MDevel::DProf coredump
+ - turn off warnings during newXS("DB::sub")

+=head1 NAME
+
+Devel::DProf - a Perl code profiler
+
+=head1 SYNOPSIS
+
+ perl5 -d:DProf test.pl
+
+=head1 DESCRIPTION
+
+The Devel::DProf package is a Perl code profiler. 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.
+
+=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>>.

+dprofpp - display perl profile data
+
+=head1 SYNOPSIS
+
+dprofpp [B<-a>|B<-z>|B<-l>|B<-v>|B<-U>] [B<-s>|B<-r>|B<-u>] [B<-q>] [B<-F>] [B<-I|-E>] [B<-O cnt>] [B<-A>] [B<-R>] [B<-S>] [B<-g subroutine>] [profile]
+
+dprofpp B<-T> [B<-F>] [B<-g subroutine>] [profile]
+
+dprofpp B<-t> [B<-F>] [B<-g subroutine>] [profile]
+
+dprofpp B<-p script> [B<-Q>] [other opts]
+
+dprofpp B<-V> [profile]
+
+=head1 DESCRIPTION
+
+The I<dprofpp> command interprets profile data produced by a profiler, such
+as the Devel::DProf profiler. Dprofpp will read the file F<tmon.out> and
+will display the 15 subroutines which are using the most time. By default
+the times for each subroutine are given exclusive of the times of their
+child subroutines.
+
+To profile a Perl script run the perl interpreter with the B<-d> switch. So
+to profile script F<test.pl> with Devel::DProf the following command should
+be used.
+
+ $ perl5 -d:DProf test.pl
+
+Then run dprofpp to analyze the profile.
+
+ $ dprofpp -u
+ Total Elapsed Time = 1.67 Seconds
+ User Time = 0.61 Seconds
+ Exclusive Times
+ %Time Seconds #Calls sec/call Name
+ 52.4 0.320 2 0.1600 main::foo
+ 45.9 0.280 200 0.0014 main::bar
+ 0.00 0.000 1 0.0000 DynaLoader::import
+ 0.00 0.000 1 0.0000 main::baz
+
+The dprofpp tool can also run the profiler before analyzing the profile
+data. The above two commands can be executed with one dprofpp command.
+
+ $ dprofpp -u -p test.pl
+
+Consult L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile.
+
+=head1 OPTIONS
+
+=over 5
+
+=item B<-a>
+
+Sort alphabetically by subroutine names.
+
+=item B<-A>
+
+Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>.
+Otherwise the time to autoload it is counted as time of the subroutine
+itself (there is no way to separate autoload time from run time).
+
+This is going to be irrelevant with newer Perls. They will inform
+C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine,
+so a separate statistics for C<AUTOLOAD> will be collected no matter
+whether this option is set.
+
+=item B<-R>
+
+Count anonymous subroutines defined in the same package separately.
+
+=item B<-E>
+
+(default) Display all subroutine times exclusive of child subroutine times.
+
+=item B<-F>
+
+Force the generation of fake exit timestamps if dprofpp reports that the
+profile is garbled. This is only useful if dprofpp determines that the
+profile is garbled due to missing exit timestamps. You're on your own if
+you do this. Consult the BUGS section.
+
+=item B<-I>
+
+Display all subroutine times inclusive of child subroutine times.
+
+=item B<-l>
+
+Sort by number of calls to the subroutines. This may help identify
+candidates for inlining.
+
+=item B<-O cnt>
+
+Show only I<cnt> subroutines. The default is 15.
+
+=item B<-p script>
+
+Tells dprofpp that it should profile the given script and then interpret its
+profile data. See B<-Q>.
+
+=item B<-Q>
+
+Used with B<-p> to tell dprofpp to quit after profiling the script, without
+interpreting the data.
+
+=item B<-q>
+
+Do not display column headers.
+
+=item B<-r>
+
+Display elapsed real times rather than user+system times.
+
+=item B<-s>
+
+Display system times rather than user+system times.
+
+=item B<-T>
+
+Display subroutine call tree to stdout. Subroutine statistics are
+not displayed.
+
+=item B<-t>
+
+Display subroutine call tree to stdout. Subroutine statistics are not
+displayed. When a function is called multiple consecutive times at the same
+calling level then it is displayed once with a repeat count.
+
+=item B<-S>
+
+Display I<merged> subroutine call tree to stdout. Statistics is
+displayed for each branch of the tree.
+
+When a function is called multiple (I<not necessarily consecutive>)
+times in the same branch then all these calls go into one branch of
+the next level. A repeat count is output together with combined
+inclusive, exclusive and kids time.
+
+Branches are sorted w.r.t. inclusive time.
+
+=item B<-U>
+
+Do not sort. Display in the order found in the raw profile.
+
+=item B<-u>
+
+Display user times rather than user+system times.
+
+=item B<-V>
+
+Print dprofpp's version number and exit. If a raw profile is found then its
+XS_VERSION variable will be displayed, too.
+
+=item B<-v>
+
+Sort by average time spent in subroutines during each call. This may help
+identify candidates for inlining.
+
+=item B<-z>
+
+(default) Sort by amount of user+system time used. The first few lines
+should show you which subroutines are using the most time.
+
+=item B<-g> C<subroutine>
+
+Ignore subroutines except C<subroutine> and whatever is called from it.
+
+=back
+
+=head1 ENVIRONMENT
+
+The environment variable B<DPROFPP_OPTS> can be set to a string containing
+options for dprofpp. You might use this if you prefer B<-I> over B<-E> or
+if you want B<-F> on all the time.
+
+This was added fairly lazily, so there are some undesirable side effects.
+Options on the commandline should override options in DPROFPP_OPTS--but
+don't count on that in this version.
+
+=head1 BUGS
+
+Applications which call _exit() or exec() from within a subroutine
+will leave an incomplete profile. See the B<-F> option.
+
+Any bugs in Devel::DProf, or any profiler generating the profile data, could
+be visible here. See L<Devel::DProf/BUGS>.
+
+Mail bug reports and feature requests to the perl5-porters mailing list at
+F<E<lt>perl5-porters@perl.orgE<gt>>. Bug reports should include the
+output of the B<-V> option.
