Software projects with multiple developers need to coordinate and synchronize the source code

Why use version control?


Version Control Repository

• Simply put, you must use a version control repository in order to perform CI

• Even if you don’t use CI, a version control repository should be standard for your project

• The purpose of a version control repository is to manage changes to source code and other software assets (such as documentation) using a controlled access repository

• There are different types of version control systems you can use too:


• Manage file sharing(Specifically: Prevent people from erasing each other’s modifications)

• Keep past versions of files/directories

• A list of exact changes made can be generated quickly and easily

• We use Subversion for most of the examples in this seminar

Version Control Repository


Svn in details


• Subversion is a leading Open Source version control system,

• tracks the history of file and directory changes over time.

• SVNKit is a pure Java Subversion toolkit that implements all Subversion features and provides APIs to work with Subversion working copies, access and manipulate Subversion repositories.

Subversion && SVNKit


SVNKit features

• Repository access over http(s), svn, svn(+ssh) and file protocols

• Repository administration • Does not require additional binaries • Turns contents of a repository to a portable dump

Repository


Subversion – Branches, Tags

• Branching and tagging are cheap (constant time) operationsBranches and tags are both implemented in terms of

an underlying "copy" operation. A copy takes up a small, constant amount of space.

BRANCH 1

Extremely fastbranching and

Tagging

„before using Subversion we waited in some projects 15 min. until a branch was created.“

Not just file management but

management of changes


Subversion - Concepts• Atomic Commits

No part of a commit takes effect until the entire commit has succeeded.

Revision numbers are per-commit, not per-file; log messages are attached to the revision, not stored redundantly as in CVS.

No inconsistence in repository because large commits happened at the same time

Files within a commit are grouped automatically so it is effident what files have been part of a change set without extra labels


Suberversion – Binary Files

• Efficient handling of binary files Subversion is equally efficient on

binary as on text files, because it uses a binary diffing algorithm to transmit and store successive revisions.

After Migration to Subversion a repository is usually between 30% smaller

Update and commit operations on binaries are much faster with subversion.
