Currently, Mac WebKit builds are failing in CI. It seems this is a regression in upstream WebKit as I'm able to reproduce it in my local environment.
The error is the following:
```
usr/bin/codesign --force --sign - --timestamp\=none --preserve-metadata\=identifier,entitlements,flags --generate-entitlement-der /Users/playwright/webkit/WebKitBuild/Release/InjectedBundleTestWebKitAPI.bundle/Contents/Resources/WebKit.framework
/Users/playwright/webkit/WebKitBuild/Release/InjectedBundleTestWebKitAPI.bundle/Contents/Resources/WebKit.framework: replacing existing signature
/Users/playwright/webkit/WebKitBuild/Release/InjectedBundleTestWebKitAPI.bundle/Contents/Resources/WebKit.framework: unsealed contents present in the root directory of an embedded framework
Command CodeSign failed with a nonzero exit code
```
Bisecting the regression it seems the build started failing on [r295496](https://trac.webkit.org/changeset/295496/webkit)
This changeset also introduced a new flag, _--no-use-workspace__, which allows to build not using WebKit.xcworkspace (I understand this is how builds were done before this changeset). Building with _--no-use-workspace_ fixes builds for Mac.
This moves default Firefox and WebKit checkouts to $HOME folder,
unless browser specific env variables are specified.
In other words:
- Firefox checkouts goes to `$HOME/firefox` unless there's a
`$FF_CHECKOUT_PATH` that specifies a custom location.
- WebKit checkout goes to `$HOME/webkit` unless there's a
`$WK_CHECKOUT_PATH` that specifies a custom location.
With this change, all build bots will now re-use checkouts
between builds, which should speed up compilation.
This way bash won't expand and post-process variable values in any way.
The changes are driven with
[`shellcheck`](https://github.com/koalaman/shellcheck)
Browsers require particular xcode versions to be installed on the host
machine to produce successful build.
This patch starts using explicit xcode versions for all mac browser
builds.
`WK_CHECKOUT_PATH` defines location of webkit checkout on the
file system. All browser-related scripts, like `prepare_checkout.sh` and
`export.sh` respect this environment variable on all platforms.
This patch changes the build system to use the JHBuild minimal dependency
system introduced in WebKit r264092 <https://trac.webkit.org/r264092>
The build has been tested with Ubuntu-18.04
The binary size of the zip bundles is now: 37M (WPE) and 40M (GTK).
Previously it was 54M and 59M (respectively)
Second try at #556. Uses absolute paths for the environment variables so that WPEDependencies builds properly. Switches from `WebKitBuildWPE` to `WebKitBuild/WPE` to avoid the need to change the .gitignore.
My computer takes a long time to build, but it appears to be working.
This patch:
- teaches `//browser_patches/webkit/build.sh` to accept the `--wpe` flag
- teaches `//browser_patches/webkit/archive.sh` to accept the `--wpe` flag
- teaches `//browser_patches/webkit/pw_run.sh` to parse the `--headless`
flag. In this case, we will assume that
`//browser_patches/webkit/checkout` is built for WPE and will pass
proper dependencies.
