When profiling SpamAssassin's mass-check command, dprofpp generates loads of errors:
Net::DNS::Resolver::Base::AUTOLOAD has -8 unstacked calls in outer File::Glob::GLOB_TILDE has 1 unstacked calls in outer POSIX::AUTOLOAD has -1 unstacked calls in outer Exporter::Heavy::heavy_export has 23 unstacked calls in outer Socket::AUTOLOAD has -6 unstacked calls in outer File::Glob::GLOB_BRACE has 1 unstacked calls in outer File::Glob::GLOB_NOMAGIC has 1 unstacked calls in outer File::Glob::AUTOLOAD has -5 unstacked calls in outer File::Glob::GLOB_QUOTE has 1 unstacked calls in outer Fcntl::AUTOLOAD has -5 unstacked calls in outer Socket::__ANON__ has 6 unstacked calls in outer POSIX::load_imports has 1 unstacked calls in outer Net::DNS::Resolver::Base::__ANON__ has 8 unstacked calls in outer Fcntl::__ANON__ has 5 unstacked calls in outer File::Glob::GLOB_ALPHASORT has 1 unstacked calls in outer Exporter::export has -23 unstacked calls in outer This seems to be a bug in Devel::DProf, rather than a bug in SpamAssassin. Is there a more up to date version of Devel::DProf we can try? (We've reproduced this on the version that comes with perl 5.6.8) Steps to reproduce: - Download SpamAssassin from SVN or Version 3.0x Trunk: svn checkout https://svn.apache.org/repos/asf/spamassassin/trunk spamassassin-trunk $ cd spamassassin/masses $ perl -d:DProf ./mass-check --file ../sample-spam.txt mass-check runs spamassassin over sample-spam.txt and returns the rules hit $ dprofpp -O1000 > /tmp/out Net::DNS::Resolver::Base::AUTOLOAD has -4 unstacked calls in outer Sys::Syslog::AUTOLOAD has -1 unstacked calls in outer File::Glob::GLOB_TILDE has 1 unstacked calls in outer POSIX::AUTOLOAD has -1 unstacked calls in outer Sys::Syslog::__ANON__ has 1 unstacked calls in outer Exporter::Heavy::heavy_export has 22 unstacked calls in outer Socket::AUTOLOAD has -5 unstacked calls in outer File::Glob::GLOB_BRACE has 1 unstacked calls in outer File::Glob::GLOB_NOMAGIC has 1 unstacked calls in outer File::Glob::AUTOLOAD has -5 unstacked calls in outer File::Glob::GLOB_QUOTE has 1 unstacked calls in outer Fcntl::AUTOLOAD has -4 unstacked calls in outer Socket::__ANON__ has 5 unstacked calls in outer POSIX::load_imports has 1 unstacked calls in outer Net::DNS::Resolver::Base::__ANON__ has 4 unstacked calls in outer Fcntl::__ANON__ has 4 unstacked calls in outer File::Glob::GLOB_ALPHASORT has 1 unstacked calls in outer Exporter::export has -22 unstacked calls in outer This behaviour has been found on Debian testing (perl 5.6.4), Debian experimental (perl 5.6.8), FreeBSD (perl 5.6.4). I can provide tmon.out if necessary.
