It's essential. You don't want everyone to be able to mess with production code.

I meant that no one ever changes anything that has ever been committed. Everyone makes changes in their own workspace and a commit becomes a new revision. Anyone can check out any revision that has ever been committed. So, each stage checks out their own appropriate revision or tagged copy based on the workflow regardless of what else is happening in the repository. It doesn't matter that someone can check in garbage, what matters is that the garbage revision not the one that QA tests/approves/tags to go to production.

How do you propose minimising the possibility of someone of ill intent making unauthorised changes?

With revision control systems, you always have access to all versions and the ability to see the differences between them and who made the changes (most useful with text/source). If something is important, I'd expect someone to review the changes as well as performing functional tests on any generated programs.

Think what DoD, any big bank, Qantas, Westfield or any other significant business would expect?

Don't they outsource everything these days?

You've got unix filesystem permissions and SELinux at your disposal to control direct repository access. And the repository doesn't have to be on the same machine as any of the users.

Unix is weak. selinux is cumbersome.

Compared to?  How could you tell if something else is better?

If you don't trust your file access control, these don't matter much.


Nobody should trust anything they're not forced to: that's what Microsoft means when it talks of "trusted computing."

Why trust the people supplying something they happen to call "trusted"?
