+=head2 Perlbug administration
-There are three (3) remote administrative interfaces for modifying bug
-status, category, etc. In all cases an admin must be first registered
-with the Perlbug database by sending an email request to
-richard@perl.org or bugmongers@perl.org.
+There is a single remote administrative interface for modifying bug status,
+category, open issues etc. using the B<RT> I<bugtracker> system, maintained
+by I<Robert Spier>. Become an administrator, and close any bugs you can get
+your sticky mitts on:
-The main requirement is the willingness to classify, (with the
-emphasis on closing where possible :), outstanding bugs. Further
-explanation can be garnered from the web at http://bugs.perl.org/ , or
-by asking on the admin mailing list at: bugmongers@perl.org
+ http://rt.perl.org

the C<[pad]THX_?> macros.
+=head2 The .i Targets
+
+You can expand the macros in a F<foo.c> file by saying
+
+ make foo.i
+
+which will expand the macros using cpp. Don't be scared by the results.

To really poke around with Perl, you'll probably want to build Perl for

Execute the given C code and print its results. B<WARNING>: Perl makes

-substitute them yourself. So, for instance, you can't say

+(see later L</"gdb macro support">). You'll have to substitute them
+yourself, or to invoke cpp on the source code files
+(see L</"The .i Targets">)
+So, for instance, you can't say
print SvPV_nolen(sv)
You may find it helpful to have a "macro dictionary", which you can
produce by saying C<cpp -dM perl.c | sort>. Even then, F<cpp> won't
-recursively apply the macros for you.

+
+=head2 gdb macro support
+
+Recent versions of F<gdb> have fairly good macro support, but
+in order to use it you'll need to compile perl with macro definitions
+included in the debugging information. Using F<gcc> version 3.1, this
+means configuring with C<-Doptimize=-g3>. Other compilers might use a
+different switch (if they support debugging macros at all).

+=item test_harness
+
+Run the test suite with the F<t/harness> controlling program, instead of
+F<t/TEST>. F<t/harness> is more sophisticated, and uses the
+L<Test::Harness> module, thus using this test target supposes that perl
+mostly works. The main advantage for our purposes is that it prints a
+detailed summary of failed tests at the end. Also, unlike F<t/TEST>, it
+doesn't redirect stderr to stdout.

+=head2 Running tests by hand
+
+You can run part of the test suite by hand by using one the following
+commands from the F<t/> directory :

+
+or
+
+ ./perl -I../lib harness list-of-.t-files
+
+(if you don't specify test scripts, the whole test suite will be run.)
+
+You can run an individual test by a command similar to
+
+ ./perl -I../lib patho/to/foo.t
+
+except that the harnesses set up some environment variables that may
+affect the execution of the test :

=head1 EXTERNAL TOOLS FOR DEBUGGING PERL
is quite unfriendly for memory debuggers.) It is suggested that you
simply kill away that testing process.
+=head2 valgrind
+
+The excellent valgrind tool can be used to find out both memory leaks
+and illegal memory accesses. As of August 2003 it unfortunately works
+only on x86 (ELF) Linux. The special "test.valgrind" target can be used
+to run the tests under valgrind. Note that in the test script (t/TEST)
+currently (as of Perl 5.8.1) only naughty memory accesses are logged,
+not memory leaks. Found errors are logged in files named F<test.valgrind>.
+Also note that with Perl built with ithreads, the glibc (at least 2.2.5)
+seems to have a bug of its own, where a non-locked POSIX mutex is
+unlocked, and valgrind catches this, for every test-- therefore the
+test script ignores that error.
