PERLBUG !!!PERLBUG NAME SYNOPSIS DESCRIPTION OPTIONS AUTHORS SEE ALSO BUGS ---- !!NAME perlbug - how to submit bug reports on Perl !!SYNOPSIS __perlbug__ [[ __-v__ ] [[ __-a__ ''address'' ] [[ __-s__ ''subject'' ] [[ __-b__ ''body'' __-f__ ''inputfile'' ] [[ __-F__ ''outputfile'' ] [[ __-r__ ''returnaddress'' ] [[ __-e__ ''editor'' ] [[ __-c__ ''adminaddress'' __-C__ ] [[ __-S__ ] [[ __-t__ ] [[ __-d__ ] [[ __-A__ ] [[ __-h__ ] __perlbug__ [[ __-v__ ] [[ __-r__ ''returnaddress'' ] [[ __-A__ ] [[ __-ok -okay -nok -nokay__ ] !!DESCRIPTION A program to help generate bug reports about perl or the modules that come with it, and mail them. If you have found a bug with a non-standard port (one that was not part of the ''standard distribution''), a binary distribution, or a non-standard module (such as Tk, CGI , etc), then please see the documentation that came with that distribution to determine the correct place to report bugs. perlbug is designed to be used interactively. Normally no arguments will be needed. Simply run it, and follow the prompts. If you are unable to run __perlbug__ (most likely because you don't have a working setup to send mail that perlbug recognizes), you may have to compose your own report, and email it to __perlbug@perl.org__. You might find the __-d__ option useful to get summary information in that case. In any case, when reporting a bug, please make sure you have run through this checklist: 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.com/ to find out. If it is not the latest released version, get that one and see whether your bug has been fixed. Note that bug reports about old versions of Perl, especially those prior to the 5.0 release, are likely to fall upon deaf ears. You are on your own if you continue to use perl1 .. perl4. 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 behavior you are witnessing doesn't fall under that category, by glancing through the documentation that comes with Perl (we'll admit this is no mean task, given the sheer volume of it all, but at least have a look at the sections that ''seem'' relevant). Be aware of the familiar traps that perl programmers of various hues fall into. See perltrap. Check in perldiag to see what any Perl error message(s) mean. If message isn't in perldiag, it probably isn't generated by Perl. Consult your operating system documentation instead. If you are on a non-UNIX platform check also perlport, as some features may be unimplemented or work differently. Try to study the problem under the Perl debugger, if necessary. See perldebug. Do you have a proper test case? The easier it is to reproduce your bug, the more likely it will be fixed, because if no one can duplicate the problem, no one can fix it. A good test case has most of these attributes: fewest possible number of lines; few dependencies on external commands, modules, or libraries; runs on most platforms unimpeded; and is self-documenting. A good test case is almost always a good candidate to be on the perl test suite. If you have the time, consider making your test case so that it will readily fit into the standard test suite. Remember also to include the __exact__ error messages, if any. ``Perl complained something'' 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 dump 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. Anything you can provide by way of insight into the problem helps 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. Use the diff program to generate your patches (diff is being maintained by the GNU folks as part of the __diffutils__ package, so you should be able to get it from any of the GNU software repositories). If you do submit a patch, the cool-dude counter at perlbug@perl.org will register you as a savior of the world. Your patch may be returned with requests for changes, or requests for more detailed explanations about your fix. Here are some clues for creating quality patches: Use the __-c__ or __-u__ switches to the diff program (to create a so-called context or unified diff). 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 you're patching supports it). 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 __perlbug@perl.org__. 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'' not informative. Neither is ``perl crashes'' nor `` HELP !!!''. These don't help. A compact description of what's wrong is fine. Having done your bit, please be prepared to wait, to be told the bug is in your code, or even to get no reply at all. The Perl maintainers are busy folks, so if your problem is a small one or if it is difficult to understand or already known, they may not respond with a personal reply. If it is important to you that your bug be fixed, do monitor the Changes file in any development releases since the time you submitted the bug, and encourage the maintainers with kind words (but never any flames!). Feel free to resend your bug report if the next released version of perl comes out and your bug is still present. !!OPTIONS __-a__ Address to send the report to. Defaults to `perlbug@perl.org'. __-A__ Don't 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__ Don't 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 don't use this option. __-S__ Send without asking for confirmation. __-s__ Subject to include with the message. You will be prompted if you don't supply one on the command line. __-t__ Test mode. The target address defaults to `perlbug-test@perl.com'. __-v__ Include verbose configuration data in the report. !!AUTHORS Kenneth Albanowski ( doc''tored by Gurusamy Sarathy ( '' !!SEE ALSO perl(1), perldebug(1), perldiag(1), perlport(1), perltrap(1), diff(1), patch(1), dbx(1), gdb(1) !!BUGS None known (guess what must have been used to report them?) ----
