This Thursday (October 8th, 13:00 UTC), Jörg Brühe will give a talk on Building MySQL Releases on Unix. Jörg will describe the tools used by the MySQL Build Team for release builds on Unix-style platforms, and present a script to simulate the essential parts of that process locally on a developer's home machine. He works at the MySQL Build Team, so you can expect in-depth insights and instructions.

If you've ever done any non-blocking programming (usually for socket I/O), you've probably had to come up with a non-trivial state machine to handle all the places where everything can pause. Say you're reading an application level packet from a socket, and half way through the read() system call it screams EAGAIN. You need to stop, save any state, and exit out of whatever chain of functions got you there so the calling application can regain control. I'm going to explain a few techniques I've come up with over the years, each with their strengths and weaknesses, and I hope this will spur some conversation of what other folks have done. While I'm fairly happy with how I handle these state machines now, I'm always looking for a more succinct way of handling things. Please share your thoughts!

Switch Statements

The obvious way to handle non-blocking I/O is with one or more switch statements. Say we …

Background

It is a pain to create binary packages.  But installing a program from source tarball is a tedious task.  You need to run ./configure & make && make install.  Sometimes you need to resolve the dependencies by hand as well.  That's where source-code-based package distribution systems come in, and the largest system is, IMHO, CPAN.  If you could upload a autotools-based distribution onto CPAN, then the users of the software can install them with the cpan command (or cpanp or cpanf or whatever), with the dependencies automatically resolved.

And for my case, it was considered especially benefitial, since the program I am now working on (it's called incline, a replicator for RDB shards using MySQL or PostgreSQL), uses perl scripts for running tests.  By distributing …
