A program to aggregate git branches from different remotes into a consolidated one

Project description

License: AGPL-3 status


Manage the aggregation of git branches from different remotes to build a consolidated one.

Configuration file

Create a repos.yaml or repos.yml file:

        acsone: git+ssh://
        - oca 8.0
        - oca refs/pull/105/head
        - oca refs/pull/106/head

        - oca 6054de2c4e669f85cec380da90d746061967dc83
        - acsone 8.0-connector_flow
        - acsone 80_connector_flow_ir_cron_able-lmi
        - acsone 8.0_connector_flow_improve_eval_config
    target: acsone aggregated_branch_name
        - oca

Environment variables inside of this file will be expanded if the proper option is selected.

All the merges are combined into a single branch. By default this branch is called _git_aggregated but another name may be given in the target section.

Fetching only required branches

If any of your merges refer to a specific commit, you will probably need to fetch all remotes from the corresponding remote or use any other strategy to get that fetch working, but we recommend to simply add this like in the example above:

    - oca
    - other-remote

You can specify that you want to fetch all references from all remotes you have defined with:

fetch_all: true

Shallow repositories

To save big amounts of bandwidth and disk space, you can use shallow clones. These download only a restricted amount of commits depending on some criteria. Available options are depth, shallow-since and shallow-exclude.

You can use those in the defaults sections to apply them everywhere, or specifying them in the corresponding merges section, for which you must use the dict alternate construction. If you need to disable a default in merges, set it to false:

        depth: 20
            remote: ocb
            ref: "9.0"
            depth: 1000
            remote: odoo
            ref: refs/pull/14859/head
    target: acsone 9.0

Remember that you need to fetch at least the common ancestor of all merges for it to succeed.


It’s also possible to specify a command or a list of shell commands to execute after the aggregation (and before the push). The commands are executed into the aggregated directory.

        acsone: git+ssh://
        - oca 8.0
    target: acsone aggregated_branch_name
    shell_command_after: echo 'my command'

        - oca 9.0
    target: acsone aggregated_branch_name
        - echo 'a first command'
        - echo 'a second command'

A real life example: applying a patch

        - oca 9.0
    target: acsone aggregated_branch_name
        - git am "$(git format-patch -1 XXXXXX -o ../patches)"

Command line Usage

Following the example repos.yaml file from above, aggregate your repositories at any time:

$ gitaggregate -c repos.yaml

Expand environment variables inside of the configuration file when loading:

$ gitaggregate -c repos.yaml --expand-env

The variables in the configuration file can be specified in one of the following ways:



For more information, see the Python’s string.Template documentation.

Use additional variables from file while expanding:

$ gitaggregate -c repos.yaml --expand-env --env-file .env

The env file should contain VAR=value lines. Lines starting with # are ignored.

You can also aggregate and automatically push the result to the target, if the target option is configured:

$ gitaggregate -c repos.yaml -p

Only aggregate a specific repository using fnmatch:

$ gitaggregate -c repos.yaml -p -d connector-interfaces

Show github pull requests

gitaggregate has a mechanism to identify merges that correpond to merged or closed Github pull requests.

Such merges are of the form refs/pull/NNN/head where NNN is the pull request number, with a or remote.

To work around API limitation, you must first generate a Github API token.

$ export GITHUB_TOKEN=...
$ gitaggregate -c repos.yaml show-all-prs
$ gitaggregate -c repos.yaml show-closed-prs


4.0 (2023-07-22)

  • [BREAKING] drop support for other configuration file formats than yaml

  • Ensure git pull is always done in fast-forward mode

  • Drop support for python 3.6, test with python 3.11, stop testing with pypy

3.0.1 (2022-09-21)

  • Fix git clone issue with git < 2.17

3.0.0 (2022-09-20)

  • When updating remotes the log message now states Updating remote instead of Remote remote

  • Add --no-color option to disable colored output

  • Use git clone –filter=blob:none + fetch strategy to improve performance and benefit from git-autoshare if installed

2.1 (August 26, 2021)

2.0 (August 17, 2021)

  • Drop support for python < 3.6

  • Do not exit with success on KeyboardInterrupt

  • Make target optional.

1.8.1 (August 28, 2020)

  • Support environment variables in the configuration file.

1.7.1 (September 30, 2019)

  • If an error happens, log in which repo it happens. Helpful when running in parallel.

1.7.0 (August 14, 2019)

  • Fix a bug in --show-all-prs, which was printing a wrong PR URL.

  • Display PR labels too in --show-all-prs.

1.6.0 (March 04, 2019)

  • Add –show-all-prs command to list all GitHub pull requests used in merge sections.

1.5.0 (December 07, 2018)

  • Add –force. If set, dirty repositories will fail to aggregate.

1.4.0 (September 13, 2018)

  • Add –jobs option for multi-process operation.

1.3.0 (August 21, 2018)

  • Improve configuration file parsing by mimicing Kaptan’s behavior of resolving handler by extension (#22)

1.2.1 (July, 12, 2018)

  • show-closed-prs now displays merge status

  • some documentation improvements

1.2.0 (May, 17, 2017)

  • support .yml config file extension

  • add a show-closed-prs command to display github pull requests that are not open anymore; github pull requests must be referenced as refs/pull/NNN/head in the merges section

1.1.0 (Feb, 01, 2017)

1.0.0 (Jan, 19, 2016)

  • First release
