# Contributing Browser Patches
|
|
|
|
Firefox and WebKit have additional patches atop to expose necessary capabilities.
|
|
|
|
Ideally, all these changes should be upstreamed.
|
|
For the time being, it is possible to setup a browser checkout
|
|
and develop from there.
|
|
|
|
## 1. Setting up local browser checkout
|
|
|
|
From the `playwright` repo, run the following command:
|
|
|
|
```sh
|
|
$ ./browser_patches/prepare_checkout.sh firefox <path to checkout>
|
|
```
|
|
(you can optionally pass "webkit" for a webkit checkout)
|
|
|
|
If you don't have a checkout, don't pass a path and one will be created for you in `./browser_patches/firefox/checkout`
|
|
|
|
> **NOTE:** this command downloads GBs of data.
|
|
|
|
|
|
This command will:
|
|
- create a `browser_upstream` remote in the checkout
|
|
- create a `playwright-build` branch and apply all playwright-required patches to it.
|
|
|
|
## 2. Developing a new change
|
|
|
|
You want to create a new branch off the `playwright-build` branch.
|
|
|
|
Assuming that you're under `./browser_patches/firefox/checkout`:
|
|
|
|
```sh
|
|
$ git checkout -b my-new-feature playwright-build
|
|
$ # develop my feature on the my-new-feature branch ....
|
|
```
|
|
|
|
## 3. Exporting your change to playwright repo
|
|
|
|
Once you're happy with the work you did in the browser-land, you want to export it to the `playwright` repo.
|
|
|
|
Assuming that you're in the root of the `playwright` repo and that your browser checkout has your feature branch checked out:
|
|
|
|
```sh
|
|
$ ./browser_patches/export.sh firefox <path to checkout>
|
|
```
|
|
|
|
This script will:
|
|
- create a new patch and put it to the `./browser_patches/firefox/patches/`
|
|
- update the `./browser_patches/firefox/UPSTREAM_CONFIG.sh` if necessary
|
|
- bump the `./browser_patches/firefox/BUILD_NUMBER` number.
|
|
|
|
If you omit the path to your checkout, the script will assume one is located at `./browser_patches/firefox/checkout`
|
|
|
|
Send a PR to the Playwright repo to be reviewed.
|
|
|
|
## 4. Rolling Playwright to the new browser build
|
|
|
|
Once the patch has been committed, the build bots will kick in, compile and upload a new browser version to all the platforms.
|
|
|
|
You can check the CDN status:
|
|
|
|
```sh
|
|
$ ./browser_patches/tools/check_cdn.sh
|
|
```
|
|
|
|
As the builds appear, you can roll to a new browser version in the `./package.json` file.
