git_sync

Script for unidirectional sync of selective git branches. Within certain workflows it is needed to sync some of the branches from one repo to another and some other branches back. The typical scenario is syncing all feature branches from working repo to the main one and integration branches back.

Usage

Setup

Create working directory. Clone the repo into it and setup the remotes you want to work with. Copy/clone the script. Edit it to have WRKDIR variable pointing to the working directory with the repos. Please use absolute path. Edit script to add sync commands to the end of it.

Fetching from remotes

It makes sense to fetch from the remotes once to avoid this step for every branch. To do this call fetch_remote function:

fetch_remote "repo" "remote1"
fetch_remote "repo" "remote2"

• repo is the name of the folder in the working directory you cloned your repo to
• remote2 and remote2 are the names of remotes configured in the repo

Syncing single branches

To run sync for a single branch you need make the following call:

sync_branch "repo" "remote1" "remote2" "master"

In this example we're syncing master branch from remote1 to remote2.

Syncing multiple branches

There is also a way to sync multiple branches without need to specify all of them:

sync_branches "repo" "remote1" "remote2" "feature/*"

As the result all the feature branches will be synced. New branches that follow the pattern will be picked up automatically.

The script does not delete any branches currently. If the branch removed from the source remote it will not be synced from the local working copy.
