Upgrading to Ruby 1.9.3 and Rails 3.2 on Windows

My Windows machine had ruby 1.9.2 and Rails 3.1. Now that ruby 1.9.3 and rails 3.2 are out, it was time to upgrade. This method isn’t the easiest, but it worked just fine for me. Note that this machine has MySQL version 5, so step 7 is necessary for me. If you have MySQL version [...]

Upgrading to ruby-1.9.2-p290

Upgrading to ruby-1.9.2-p290 on my development machines (Windows and Linux) was a breeze. There were some extra steps needed to upgrade on the server:

After that, just:

3. rvm install ruby-1.9.2-p290
4. rvm –default 1.9.2-p290
5. rvm gemset create 3.1.1
6. rvm gemset use 3.1.1 –default
7. gem install rails –no-rdoc –no-ri

and ready to roll.

Rails 3.1 Is Out!

uninitialized constant Rake::DSL

Using Ruby 1.9.2, Rails 3.0.9, and rake 0.9.2

ruby.exe – Unable To Locate Component
This application has failed to start because msvcrt-ruby18.dll was not found. Re-installing the application may fix the problem.

The solution turns out to be easy. Update old gems that still use ruby 1.8. In my case:

Installing ruby 1.9.2p0 and Rails 3.0.3 and getting it to work with MySQL on Windows

Installing ruby 1.9.2 on Windows took several false starts before I got on the right track.

My development machine is a dual-boot Windows and Linux monster with pre-existing versions of Ruby, Rubygems, Rails, and MySQL. On the Windows side, I have a working version using ruby 1.86, rubygems 1.3.5, rails 2.3.8, and MySQL 5.1. The oldest [...]

Rails 2.3.8 - Segmentation Fault

I just upgraded to Rails 2.3.8 on my development machine. I created a standard Rails app, started up WEBrick, and got a Segmentation fault. Not enough code to be my error, so I searched for the core problem and possible solutions.

Turns out the issue is known, and a solution exists. First, I updated to the [...]

SquirrelMail – change_sqlpass plugin

Found a bug in the squirrelmail change_sqlpass plugin. Made the ugly fix; gonna dive in and write a patch later.

The bug occurs in functions.php

There is a mismatch between:
function get_password_salt, where the program reasonably returns the value of the password salt when $csp_salt_static is empty and $csp_salt_query is not empty.

and:
function get_password_encrypt_string, in the switch statement,
it uses [...]
