266 # Explain what perlbug is
269 This program provides an easy way to create a message reporting a bug
270 in perl, and e-mail it to $address. It is *NOT* intended for
271 sending test messages or simply verifying that perl works, *NOR* is it
272 intended for reporting bugs in third-party perl modules. It is *ONLY*
273 a means of reporting verifiable problems with the core perl distribution,
274 and any solutions to such problems, to the people who maintain perl.
276 If you're just looking for help with perl, try posting to the Usenet
277 newsgroup comp.lang.perl.misc. If you're looking for help with using
278 perl with CGI, try posting to comp.infosystems.www.programming.cgi.
282 # Prompt for subject of message, if needed

287 the bug or problem. "perl bug" or "perl problem"
288 is not a concise description.

774 A program to help generate bug reports about perl5, and mail them.
775 It is designed to be used interactively. Normally no arguments will
779 $0 [-v] [-a address] [-s subject] [-b body | -f inpufile ] [ -F outputfile ]
780 [-r returnaddress] [-e editor] [-c adminaddress | -C] [-S] [-t] [-h]
781 $0 [-v] [-r returnaddress] [-ok | -okay | -nok | -nokay]
783 Simplest usage: run "$0", and follow the prompts.
787 -v Include Verbose configuration data in the report
788 -f File containing the body of the report. Use this to
789 quickly send a prepared message.
790 -F File to output the resulting mail message to, instead of mailing.
791 -S Send without asking for confirmation.
792 -a Address to send the report to. Defaults to `$address'.
793 -c Address to send copy of report to. Defaults to `$cc'.
794 -C Don't send copy to administrator.
795 -s Subject to include with the message. You will be prompted
796 if you don't supply one on the command line.
797 -b Body of the report. If not included on the command line, or
798 in a file with -f, you will get a chance to edit the message.
799 -r Your return address. The program will ask you to confirm
800 this if you don't give it here.
802 -t Test mode. The target address defaults to `$testaddress'.
803 -d Data mode (the default if you redirect or pipe output.)
804 This prints out your configuration data, without mailing
805 anything. You can use this with -v to get more complete data.
806 -ok Report successful build on this system to perl porters
807 (use alone or with -v). Only use -ok if *everything* was ok:
808 if there were *any* problems at all, use -nok.
809 -okay As -ok but allow report from old builds.
810 -nok Report unsuccessful build on this system to perl porters
811 (use alone or with -v). You must describe what went wrong
812 in the body of the report which you will be asked to edit.
813 -nokay As -nok but allow report from old builds.

866 If you have found a bug with a non-standard port (one that was not part
867 of the I<standard distribution>), a binary distribution, or a
868 non-standard module (such as Tk, CGI, etc), then please see the
869 documentation that came with that distribution to determine the correct
870 place to report bugs.
872 C<perlbug> is designed to be used interactively. Normally no arguments
873 will be needed. Simply run it, and follow the prompts.
875 If you are unable to run B<perlbug> (most likely because you don't have
876 a working setup to send mail that perlbug recognizes), you may have to
877 compose your own report, and email it to B<perlbug@perl.com>. You might
878 find the B<-d> option useful to get summary information in that case.
880 In any case, when reporting a bug, please make sure you have run through
885 =item What version of perl you are running?
887 Type C<perl -v> at the command line to find out.
889 =item Are you running the latest released version of perl?
891 Look at http://www.perl.com/ to find out. If it is not the latest
892 released version, get that one and see whether your bug has been
893 fixed. Note that bug reports about old versions of perl, especially
894 those prior to the 5.0 release, are likely to fall upon deaf ears.
895 You are on your own if you continue to use perl1 .. perl4.
897 =item Are you sure what you have is a bug?
899 A significant number of the bug reports we get turn out to be documented
900 features in perl. Make sure the behavior you are witnessing doesn't fall
901 under that category, by glancing through the documentation that comes
902 with perl (we'll admit this is no mean task, given the sheer volume of
903 it all, but at least have a look at the sections that I<seem> relevant).
905 Be aware of the familiar traps that perl programmers of various hues
906 fall into. See L<perltrap>.
908 Check in L<perldiag> to see what any Perl error message(s) mean.
909 If message isn't in perldiag, it probably isn't generated by Perl.
910 Consult your operating system documentation instead.
912 If you are on a non-UNIX platform check also L<perlport>, some
913 features may not be implemented or work differently.
915 Try to study the problem under the perl debugger, if necessary.
918 =item Do you have a proper test case?
920 The easier it is to reproduce your bug, the more likely it will be
921 fixed, because if no one can duplicate the problem, no one can fix it.
922 A good test case has most of these attributes: fewest possible number
923 of lines; few dependencies on external commands, modules, or
924 libraries; runs on most platforms unimpeded; and is self-documenting.
926 A good test case is almost always a good candidate to be on the perl
927 test suite. If you have the time, consider making your test case so
928 that it will readily fit into the standard test suite.
930 Remember also to include the B<exact> error messages, if any.
931 "Perl complained something" is not an exact error message.
933 If you get a core dump (or equivalent), you may use a debugger
934 (B<dbx>, B<gdb>, etc) to produce a stack trace to include in the bug
935 report. NOTE: unless your Perl has been compiled with debug info
936 (often B<-g>), the stack trace is likely to be somewhat hard to use
937 because it will most probably contain only the function names, not
938 their arguments. If possible, recompile your Perl with debug info and
939 reproduce the dump and the stack trace.
941 =item Can you describe the bug in plain English?
943 The easier it is to understand a reproducible bug, the more likely it
944 will be fixed. Anything you can provide by way of insight into the
945 problem helps a great deal. In other words, try to analyse the
946 problem to the extent you feel qualified and report your discoveries.
948 =item Can you fix the bug yourself?
950 A bug report which I<includes a patch to fix it> will almost
951 definitely be fixed. Use the C<diff> program to generate your patches
952 (C<diff> is being maintained by the GNU folks as part of the B<diffutils>
953 package, so you should be able to get it from any of the GNU software
954 repositories). If you do submit a patch, the cool-dude counter at
955 perlbug@perl.com will register you as a savior of the world. Your
956 patch may be returned with requests for changes, or requests for more
957 detailed explanations about your fix.
959 Here are some clues for creating quality patches: Use the B<-c> or
960 B<-u> switches to the diff program (to create a so-called context or
961 unified diff). Make sure the patch is not reversed (the first
962 argument to diff is typically the original file, the second argument
963 your changed file). Make sure you test your patch by applying it with
964 the C<patch> program before you send it on its way. Try to follow the
965 same style as the code you are trying to patch. Make sure your patch
966 really does work (C<make test>, if the thing you're patching supports
969 =item Can you use C<perlbug> to submit the report?
971 B<perlbug> will, amongst other things, ensure your report includes
972 crucial information about your version of perl. If C<perlbug> is unable
973 to mail your report after you have typed it in, you may have to compose
974 the message yourself, add the output produced by C<perlbug -d> and email
975 it to B<perlbug@perl.com>. If, for some reason, you cannot run
976 C<perlbug> at all on your system, be sure to include the entire output
977 produced by running C<perl -V> (note the uppercase V).
979 Whether you use C<perlbug> or send the email manually, please make
980 your subject informative. "a bug" not informative. Neither is "perl
981 crashes" nor "HELP!!!", these all are null information. A compact
982 description of what's wrong is fine.
986 Having done your bit, please be prepared to wait, to be told the bug
987 is in your code, or even to get no reply at all. The perl maintainers
988 are busy folks, so if your problem is a small one or if it is difficult
989 to understand or already known, they may not respond with a personal reply.
990 If it is important to you that your bug be fixed, do monitor the
991 C<Changes> file in any development releases since the time you submitted
992 the bug, and encourage the maintainers with kind words (but never any
993 flames!). Feel free to resend your bug report if the next released
994 version of perl comes out and your bug is still present.
