perlhack - How to hack at the Perl internals
DESCRIPTION
Does concept match the general goals of Perl?, Where is the imple-
mentation?, 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 implemen-
tation robust?, Is the implementation generic enough to be
portable?, Is the implementation tested?, Is there enough documen-
tation?, 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 to rsync the source tree, It's more reliable
Why rsync the patches
It's easier to rsync the patches, It's a good reference, Find-
ing a start point, Finding how to fix a bug, Finding the source
of misbehaviour

Matching Partial Keys
DB_RECNO
The 'bval' Option
A Simple Example
Extra RECNO Methods
$X->push(list) ;, $value = $X->pop ;, $X->shift,
$X->unshift(list) ;, $X->length, $X->splice(offset, length,
elements);
Another Example
THE API INTERFACE
$status = $X->get($key, $value [, $flags]) ;, $status =
$X->put($key, $value [, $flags]) ;, $status = $X->del($key [,
$flags]) ;, $status = $X->fd ;, $status = $X->seq($key, $value,
$flags) ;, $status = $X->sync([$flags]) ;
DBM FILTERS
filter_store_key, filter_store_value, filter_fetch_key, fil-
ter_fetch_value
The Filter
An Example -- the NULL termination problem.
Another Example -- Key is a C int.

Filter::Simple - Simplified source filtering
SYNOPSIS
DESCRIPTION
The Problem
A Solution
Disabling or changing <no> behaviour
All-in-one interface
Filtering only specific components of source code
"code", "executable", "quotelike", "string", "regex", "all"
Filtering only the code parts of source code
Most source code ceases to be grammatically correct when it is
broken up into the pieces between string literals and regexes.
So the 'code' component filter behaves slightly differently
from the other partial filters described in the previous sec-
tion.

Obtaining and installing libnet
What is libnet ?
Which version of perl do I need ?
What other modules do I need ?
What machines support libnet ?
Where can I get the latest libnet release
Using Net::FTP
How do I download files from an FTP server ?
How do I transfer files in binary mode ?
How can I get the size of a file on a remote FTP server ?
How can I get the modification time of a file on a remote FTP
server ?
How can I change the permissions of a file on a remote server ?
Can I do a reget operation like the ftp command ?
How do I get a directory listing from an FTP server ?
Changing directory to "" does not fail ?
I am behind a SOCKS firewall, but the Firewall option does not work
?
I am behind an FTP proxy firewall, but cannot access machines out-
side ?
My ftp proxy firewall does not listen on port 21
Is it possible to change the file permissions of a file on an FTP
server ?
I have seen scripts call a method message, but cannot find it docu-
mented ?
Why does Net::FTP not implement mput and mget methods
Using Net::SMTP
Why can't the part of an Email address after the @ be used as the
hostname ?
Why does Net::SMTP not do DNS MX lookups ?
The verify method always returns true ?
Debugging scripts
How can I debug my scripts that use Net::* modules ?
