|What version of Perl you are running?||Type perl -v at the command line to find out.|
|Are you running the latest released version of perl?||
Look at http://www.perl.org/ to find out. If you are not using the
latest released version, please try to replicate your bug on the
latest stable release.
Note that reports about bugs in old versions of Perl, especially those which indicate you havent also tested the current stable release of Perl, are likely to receive less attention from the volunteers who build and maintain Perl than reports about bugs in the current release.
This tool isnt appropriate for reporting bugs in any version prior to Perl 5.0.
|Are you sure what you have is a bug?||
A significant number of the bug reports we get turn out to be
documented features in Perl. Make sure the issue youve run into
isnt intentional by glancing through the documentation that comes
with the Perl distribution.
Given the sheer volume of Perl documentation, this isnt a trivial undertaking, but if you can point to documentation that suggests the behaviour youre seeing is wrong, your issue is likely to receive more attention. You may want to start with perldoc perltrap for pointers to common traps that new (and experienced) Perl programmers run into.
If youre unsure of the meaning of an error message youve run across, perldoc perldiag for an explanation. If the message isnt in perldiag, it probably isnt generated by Perl. You may have luck consulting your operating system documentation instead.
|Do you have a proper test case?||
The easier it is to reproduce your bug, the more likely it will be
fixed if nobody can duplicate your problem, it probably wont be
A good test case has most of these attributes: short, simple code; few dependencies on external commands, modules, or libraries; no platform-dependent code (unless its a platform-specific bug); clear, simple documentation.
A good test case is almost always a good candidate to be included in Perls test suite. If you have the time, consider writing your test case so that it can be easily included into the standard test suite.
|Have you included all relevant information?||
Be sure to include the exact error messages, if any.
Perl gave an error is not an exact error message.
If you get a core dump (or equivalent), you may use a debugger (dbx, gdb, etc) to produce a stack trace to include in the bug report.
NOTE: unless your Perl has been compiled with debug info (often -g), the stack trace is likely to be somewhat hard to use because it will most probably contain only the function names and not their arguments. If possible, recompile your Perl with debug info and reproduce the crash and the stack trace.
|Can you describe the bug in plain English?||The easier it is to understand a reproducible bug, the more likely it will be fixed. Any insight you can provide into the problem will help a great deal. In other words, try to analyze the problem (to the extent you can) and report your discoveries.|
|Can you fix the bug yourself?||
A bug report which includes a patch to fix it will almost
definitely be fixed. When sending a patch, please use the diff
program with the -u option to generate unified diff files.
Bug reports with patches are likely to receive significantly more
attention and interest than those without patches.
Your patch may be returned with requests for changes, or requests for more detailed explanations about your fix.
Here are a few hints for creating high-quality patches:
Make sure the patch is not reversed (the first argument to diff is typically the original file, the second argument your changed file). Make sure you test your patch by applying it with the patch program before you send it on its way. Try to follow the same style as the code you are trying to patch. Make sure your patch really does work (make test, if the thing youre patching is covered by Perls test suite).
|Can you use perlbug to submit the report?||
perlbug will, amongst other things, ensure your report includes
crucial information about your version of perl. If perlbug is
unable to mail your report after you have typed it in, you may have
to compose the message yourself, add the output produced by perlbug
-d and email it to email@example.com. If, for some reason, you
cannot run perlbug at all on your system, be sure to include the
entire output produced by running perl -V (note the uppercase V).
Whether you use perlbug or send the email manually, please make your Subject line informative. a bug is not informative. Neither is perl crashes nor is HELP!!!. These dont help. A compact description of whats wrong is fine.
|Can you use perlbug to submit a thank-you note?||Yes, you can do this by either using the -T option, or by invoking the program as perlthanks. Thank-you notes are good. It makes people smile.|
If it is important to you that your bug be fixed, do monitor the firstname.lastname@example.org mailing list and the commit logs to development versions of Perl, and encourage the maintainers with kind words or offers of frosty beverages. (Please do be kind to the maintainers. Harassing or flaming them is likely to have the opposite effect of the one you want.)
Feel free to update the ticket about your bug on http://rt.perl.org if a new version of Perl is released and your bug is still present.
-a Address to send the report to. Defaults to email@example.com. -A Dont send a bug received acknowledgement to the reply address. Generally it is only a sensible to use this option if you are a perl maintainer actively watching perl porters for your message to arrive. -b Body of the report. If not included on the command line, or in a file with -f, you will get a chance to edit the message. -C Dont send copy to administrator. -c Address to send copy of report to. Defaults to the address of the local perl administrator (recorded when perl was built). -d Data mode (the default if you redirect or pipe output). This prints out your configuration data, without mailing anything. You can use this with -v to get more complete data. -e Editor to use. -f File containing the body of the report. Use this to quickly send a prepared message. -F File to output the results to instead of sending as an email. Useful particularly when running perlbug on a machine with no direct internet connection. -h Prints a brief summary of the options. -ok Report successful build on this system to perl porters. Forces -S and -C. Forces and supplies values for -s and -b. Only prompts for a return address if it cannot guess it (for use with make). Honors return address specified with -r. You can use this with -v to get more complete data. Only makes a report if this system is less than 60 days old. -okay As -ok except it will report on older systems. -nok Report unsuccessful build on this system. Forces -C. Forces and supplies a value for -s, then requires you to edit the report and say what went wrong. Alternatively, a prepared report may be supplied using -f. Only prompts for a return address if it cannot guess it (for use with make). Honors return address specified with -r. You can use this with -v to get more complete data. Only makes a report if this system is less than 60 days old. -nokay As -nok except it will report on older systems. -r Your return address. The program will ask you to confirm its default if you dont use this option. -S Send without asking for confirmation. -s Subject to include with the message. You will be prompted if you dont supply one on the command line. -t Test mode. The target address defaults to firstname.lastname@example.org. -T Send a thank-you note instead of a bug report. -v Include verbose configuration data in the report.
