Installing

$ pipx install oca-port
$ #OR
$ git clone git@github.com:oca/oca-port.git
$ cd oca-port
$ pipx install .

To automatically apply code patterns with odoo-module-migrator, install library with below syntax:

$ pipx inject --include-deps  oca-port git+https://github.com/OCA/odoo-module-migrator.git@master

Using

If the addon does not exist on the target branch, it will assist the user in the migration, following the OCA migration guide.

If the addon already exists on the target branch, it will retrieve commits not fully ported grouped by Pull Request and propose to port them.

Syntax:

$ oca-port <source> <target> <module_path> [options]
$ oca-port --help

GitHub Token

GITHUB_TOKEN can be passed by exposing to environment:

$ export GITHUB_TOKEN=<token>

Alternatively, you can pass the token directly using the --github-token option

If neither method is used, the tool will attempt to obtain the token using the gh client (if it's installed).

Example

To check if an addon could be migrated or to get eligible commits to port:

$ cd <path/to/OCA/cloned_repository>
$ oca-port origin/16.0 origin/18.0 <module_path> --verbose --dry-run

To effectively migrate the addon or port its commits, remove the --dry-run option so the tool will create a working local branch automatically (called destination) from the <target> branch:

$ oca-port origin/16.0 origin/18.0 <module_path>

You can control the destination with the --destination option:

$ oca-port origin/16.0 origin/18.0 <module_path> --destination camptocamp/18.0-port-things

Module located in subfolder

The module can be located in a subfolder, and the tool can be used in any kind of repository, e.g:

$ oca-port origin/main origin/18.0-mig --source-version=16.0 --target-version=18.0 --upstream-org=camptocamp ./odoo/local-src/MY_MODULE --verbose --destination sebalix/18.0-mig-MY_MODULE

• parameters --source-version and --target-version are mandatory as soon as the source/target parameters cannot be recognized as Odoo versions (here origin/main is hosting a 16.0 version)
• --upstream-org defaults to OCA, here we set it to camptocamp for GitHub API requests

Move/rename a module

To move or rename a module, the --move-to parameter can be used:

$ oca-port origin/16.0 origin/18.0 <module_path> --move-to <new_module_path>

NOTE: the rename will be handled thanks to git-filter-repo so the whole git history will be available in the new folder.

Blacklist

You can also directly blacklist a bunch of PRs on a given branch thanks to the oca-port-pr tool:

$ oca-port-pr blacklist OCA/wms#250,OCA/wms#251 16.0 shopfloor

You could give a more detailed reason of this blacklist with --reason parameter:

$ oca-port-pr blacklist OCA/wms#250,OCA/wms#251 16.0 shopfloor --reason "Refactored in 16.0, not needed anymore"

And if the module has been moved to another repository, you can specify its remote as well:

$ git remote add new_repo git@github.com:OCA/new-repo.git
$ oca-port-pr blacklist OCA/wms#250,OCA/wms#251 16.0 shopfloor --remote new_repo

Migration of addon

The tool follows the usual OCA migration guide to port commits of an addon, and will invite the user to fullfill the mentionned steps that can't be performed automatically.

Output example:

If used with the --non-interactive option, the returned exit code is 100 if an addon could be migrated.

Port of commits/Pull Requests

The tool will ask the user if he wants to open draft pull requests against the upstream repository.

If there are several Pull Requests to port, it will ask the user if he wants to base the next PR on the previous one, allowing the user to cumulate ported PRs in one branch and creating a draft PR against the upstream repository with all of them.

More details here : OCA Days 2022 - Sébastien Alix and Simone Orsi: oca-port:new OCA tool to help with modules migration

Output example (with --verbose):

If used with the --non-interactive option, the returned exit code is 110 if some pull requests/commits could be ported.

API

You can also use oca-port as a Python package:

>>> import oca_port,json
>>> app = oca_port.App(
...     source="origin/14.0",
...     target="origin/16.0",
...     addon_path="stock_move_auto_assign",
...     upstream_org="OCA",
...     repo_path="/home/odoo/OCA/stock-logistics-warehouse",
...     output="json",
...     fetch=True,
...     github_token="<TOKEN>"
... )
>>> json_data = app.run()
>>> data = json.loads(json_data)
>>> from pprint import pprint as pp
>>> pp(data)
