Back in the Groove

After taking off the afternoon due to a migraine, and napping for a few hours until it passed, I was looking over some old projects, and decided to get motivated to work on my various Erlang hackery projects. I checked out a fresh copy of Open Server Platform on my new computer, and decided to hack on it some more. There are a number of loose ends I’d like to tie up before the 0.3 release, but, before I could get down to coding, SVN get my so frustrated that I could no longer deal with it and switched to git, creating a new repository on Github. I will keep the Google Code repository the ‘defacto’ repository, where the safer code gets committed, but use Github for the more bleeding edge development due to it’s simplified branching and merging (among other things).

In the new git setup, I have two branches (aside from master, which follows the SVN repository): otp and no-otp. The no-otp version is currently the stable code that runs just fine, but doesn’t take advantage of Erlang’s OTP framework. The otp branch is the more cutting edge OTP aware version, which I hope to fully migrate to soon. With full support for OTP, I should be able to use an already existing distribution platform, and more battle tested redundancy.

This evening, I fixed a long standing bug in the example HTTPd where the server would crash when opening large files due to a shortcut I took with first implementing the server. Originally, the server would read the entire file into a string and then send that to the client, as you can probably see, there is a problem when the server tries to read in a 3.9 GB file (my test file). Now, my servlet takes a much more sane approach, read in the file 1 kilobyte at time, sending that to the client before reading more. This new approach works perfectly, though I had to add some messiness for handling CGI/PHP files and different MIME types. I also added support for the HTTP HEAD command.

Peace and chow,
