Git vs Subversion

DISTRIBUTED VS CENTRALIZED

Git is distributed, SVN is not• Designed from the ground up to be fully distributed

• Git has multiple redundant repositories, not one

• You never lose code even if the server explodes

• Developers can work offline

• very important for distributed teams

• Developers work much faster (no latency)

BRANCHING AND WORKFLOW

Branches are first-class concepts in Git

• in SVN branches are based on folders structure

• Git branches are simpler and less resource

heavy than Subversion’s

• Git branches carry their entire history

• Git supports any type of workflow not only

Centralized one

• Git is much more suited for proper Versioning

and Release Process

GIT USABILITY

• High productively without network connection

• Most operations could be done offline • Perform a diff;

• View file history;

• Commit changes;

• Merge branches;

• Obtain any other revision of a file;

• Switch branches.

• Makes most operations much faster since no network is involved

• Allows participation in projects without requiring permissions from project authorities, and

thus arguably better fosters culture of meritocracy instead of requiring “committer” status

• Allows private work, so users can use their revision control system even for early drafts

they do not want to publish

• Avoids relying on a single physical machine as a single point of failure.

• Still permits centralized control of the “release version” of the project

OTHER CONSIDERATIONS

• Git stores content as metadata, SVN stores just files

• Git's repos are much smaller than Subversions

• for example, Mozilla code is 30x smaller in Git

• Developers often have to use Git anyway to work with open-source

libraries

• Automatic line ending conversion (CRLF or LF)

• Git’s content integrity is better than SVN’s as it is based on based

SHA-1 checksums

• Used and loved by millions of developers

• developers’ satisfaction is important for productivity

• Fantastic enterprise grade solutions based on Git (see below)

VERDICT

Git is highly recommended
