Fun with ones and zeros - amqp

amqplib 1.0.0

2011-08-08T11:24:00-07:00

I attended OSCON for the first time this year, and to celebrate I thought I'd wrap up the Python amqplib library a bit and consider it more-or-less finished for what it is (a simple blocking 0-8 client), and call it 1.0.0 You can find it on the in PyPi and Google Project Hosting

It's definitely a worthwhile upgrade in that it's significantly faster than amqplib 0.6.1, and has a fair number of bug fixes. Also noteworthy are support for Python 3.x (via 2to3) and IPv6

amqplib and bpgsql on Google Code

I've created Google Code projects for my amqplib and bpgsql packages, to take advantage of their nice infrastructure including issue tracking.

amqplib 0.6

2009-01-19T09:31:00-08:00

Wrapped up another release of py-amqplib, version 0.6 - which features a major reorganization of the codebase to make the library more maintainable and lays the groundwork for an optional thread-assisted mode that allows for flow control and timeouts (being worked on in a development repository).

Building additional PHP modules on OSX

2008-12-08T20:09:00-08:00

Normally I try to avoid dealing with PHP if at all possible, but there is now a PHP port of py-amqplib called php-amqplib, and I offered to help out with it a bit. Maybe partially out of guilt for having written the mess of Python code it was based on :)

I thought it would be handy to work on it using my MacBook. OS X 10.5 (Leopard) has PHP 5.2.6 built in standard, but unfortunately it doesn't have the bcmath extension included, which php-amqplib makes use of. Turns out building the module wasn't that difficult. This page got me going - although building bcmath was much simpler. Since I had the Apple Developer Tools for 10.5 installed, it was just a matter of ...

mkdir /SourceCache
cd /SourceCache
fetch https://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror
tar xzvf php-5.2.6.tar.gz
cd php-5.2.6/ext/bcmath
phpize
./configure
make
sudo make install
cd /etc
cp php.ini.default php.ini

And then edit /etc/php.ini to make these two changes:

--- php.ini.default     2008-07-15 14:19:15.000000000 -0500
+++ php.ini     2008-12-08 21:44:52.000000000 -0600

After that, I was able to run the amqp_test.php file for the first time, sending a message and receiving it in py-amqplib's demo/demo_receive.py

RabbitMQ FreeBSD port

2008-09-01T17:29:06-07:00

I was happy to see a FreeBSD port added for RabbitMQ, net/rabbitmq, although I found a couple problems with it: it doesn't start automatically when your machine or jail boots, and when building the rabbitmq-erlang-client, it errors out with:

src/amqp_channel.erl:28: can't find include lib "rabbitmq_server/include/rabbit.hrl"
src/amqp_channel.erl:29: can't find include lib "rabbitmq_server/include/rabbit_framing.hrl"

I worked on the port a bit, and submitted a bug report and patch, ports/127033, that fixes these problems.
