perlhack - How to hack at the Perl internals

DESCRIPTION

Does concept match the general goals of Perl?, Where is the implementation?, Backwards compatibility, Could it be a module instead?, Is the feature generic enough?, Does it potentially introduce new bugs?, Does it preclude other desirable features?, Is the implementation robust?, Is the implementation generic enough to be portable?, Is there enough documentation?, Is there another way to do it?, Does it create too much work?, Patches speak louder than words

Keeping in sync

rsync'ing the source tree, Using rsync over the LAN, Using pushing over the NFS, rsync'ing the patches

Why rsync the source tree

It's easier, It's more recent, It's more reliable

Why rsync the patches

It's easier, It's a good reference, Finding a start point, Finding how to fix a bug, Finding the source of misbehaviour

SYNOPSIS
DESCRIPTION
Unpacking

Don't turn on the compiler optimization flag "-O". There's a bug in the compiler (APAR PQ18812) that generates some bad code the optimizer is on, As VM/ESA doesn't fully support the fork() API programs relying on this call will not work. I've replaced fork()/exec() with spawn() and the standalone exec() with spawn(). This has a side effect when opening unnamed pipes in a shell script: there is no child process generated under

Usage Hints

When using perl on VM/ESA please keep in mind that the EBCDIC and ASCII character sets are different. Perl builtin functions that may behave differently under EBCDIC are mentioned in the perlport.pod document.
