Working in a
team?
Most commercial programming is
done in teams
To simplify project management
and enforce accountability, version
control is used
What is revision control?
WITHOUT
WITH
If a team creates a bug, it could
affect how your code too
You are isolated on your own
branch, so you know who did it
You could loose old code or
features that were removed
You can go back and see all old
version of your project
Anyone could add bugs/features to
a project and no one would know
Someone has to approve your code
submission
Lingo
The Basics
Repository – the database holding your
code
Main/Trunk – This is the primary code
Working set – A file you checked out
Tags – the name of the project stage
Actions
Check out – a downloaded file
Check in – uploading the file
Update – synchronizes your code
Revert – toss the changes you made
More complicated
Branch – create a separate copy of a file
or folder
Diff – (I bet you know)
Merge – combining branches
But how does one “branch”?
That’s how Linux is made
(kinda)
