I recently upgraded the Project Management Software, which happened to be Redmine, for a company and after the upgrade I received some complaints regarding SVN not functioning properly. I initially thought there is no way that the upgrade caused an issue with SVN since SVN and Redmine are completely separate however you can browse the SVN repositories from within Redmine. Below I describe the error in more detail including an image of the error from TortoiseSVN, what I did to resolve the issue, and another possible resolution if your issue is different than the one mentioned in this article.
To install the latest git on CentOS 5 you will need to install from source since the yum repos are typically fairly far behind. Follow the instructions below and installing git on CentOS 5.X will be a snap.
Migrations as version control for databases
When I first learned about Rails migration, I immediately thought that dropping down a revision would be something you would do often. In actuality, Rails migrations is more like a version control for databases. Since databases changes require modifications to both code and data, you cannot simply use a source code version control system like Subversion or Sourcesafe. You need a more advanced revisioning system for databases… hence Rails Migrations.
