GIT auto merge tool

merGeIT allows to handle git push events and do automatic merges according to configured branch dependencies.

First of all you define branch dependencies in a way "source-target branches". The source branch is defined as regular expression. All target branches are defined as list under source branch section.

Optionally filters and hooks can be defined for each dependency. Filters can cancel merge or change target branch before merge depending on push event info. Hooks are mostly used to send notifications about merge result, close tasks in task manager or cancel push merge if i. e. unittests fails.

When push event occurs on some branch, push handler matches name of this branch across all patterns and runs merge process for source into target. The merge process is completed in 3 steps:

• Executing filters
• Actual GIT merge operation
• Executing hooks
• GIT push operation

Both filters and hooks has ability to cancel merge process.

• Branch dependencies using regexp for source (push) branch matching and list of target (merge) branches
• Filters to control merging flow with specific logic
• Hooks to notify about success/fail merge events

For each project (repo) there should be one YAML config that defines all branch dependencies and filters/hooks definitions/uses.

The following example explains how to set up simple scheme "Keep develop branch up-to-date with master updates":

merGeIT comes with some helpful filters and hooks for Redmine and GitLab located in extras module. You can implement similar things for any other software you use. Also, feel free to make pull request to add them to merGeIT repo ;)

Run hook handle server:

mergeit -H 0.0.0.0 -p 1234 -sh 0.0.0.0 -sp 1235 -c config_samples/full.yaml -l test-repo

Display help:

mergeit -h

Run shell (for manual commands):

mergeit-shell -c config_samples/full.yaml -l test.log

Connect to server's same shell via telnet (while mergeit server running):

telnet localhost 1235

Coming soon

Install package:

python3 setup.py install

Run tests (optionally):

python3 -m unittest discover tests

• Add support for raw git push hooks (not only gitlab)
• Add ability to configure git remotes somehow
