A library to aggregate git branches from different remotes into a consolidated one
Manage the aggregation of git branches from different remotes to build a consolidated one.
Create a repos.yaml or repos.yml file:
./product_attribute: remotes: oca: https://github.com/OCA/product-attribute.git acsone: git+ssh://firstname.lastname@example.org/acsone/product-attribute.git merges: - oca 8.0 - oca refs/pull/105/head - oca refs/pull/106/head target: acsone aggregated_branch_name ./connector-interfaces: remotes: oca: https://github.com/OCA/connector-interfaces.git acsone: https://github.com/acsone/connector-interfaces.git merges: - 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 fetch_all: - oca
Environment variables inside of this file will be expanded if the proper option is selected.
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:
fetch_all: - oca - other-remote
You can specify that you want to fetch all references from all remotes you have defined with:
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.
Available options depend on server and client Git version, be sure to use options available for your environment.
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:
./odoo: defaults: depth: 20 remotes: odoo: https://github.com/odoo/odoo.git ocb: https://github.com/OCA/OCB.git acsone: https://github.com/acsone/odoo.git merges: - 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.
./product_attribute: remotes: oca: https://github.com/OCA/product-attribute.git acsone: git+ssh://email@example.com/acsone/product-attribute.git merges: - oca 8.0 target: acsone aggregated_branch_name shell_command_after: echo 'my command' ./connector-interfaces: remotes: oca: https://github.com/OCA/connector-interfaces.git acsone: https://github.com/acsone/connector-interfaces.git merges: - oca 9.0 target: acsone aggregated_branch_name shell_command_after: - echo 'a first command' - echo 'a second command'
A real life example: applying a patch
./odoo: remotes: oca: https://github.com/OCA/OCB.git acsone: firstname.lastname@example.org/acsone/OCB.git merges: - oca 9.0 target: acsone aggregated_branch_name shell_command_after: - 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:
$ 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.
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
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)

- 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

- Shallow repositories. (https://github.com/acsone/git-aggregator/pull/7)
- Fetch only required remotes. (https://github.com/acsone/git-aggregator/pull/6)
- Display readable error if config file not found. (https://github.com/acsone/git-aggregator/pull/2)
