`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.
**Preamble**
1. We're trying to setup a windows-based github self-hosted runner in the
playwright-internal repo.
1. Commands on Windows are mandated to have total arguments length
less then 32767 characters.
1. On windows, github self-hosted runner framework puts repository
checkout at `c:\w\playwright-internal\playwright-internal`
1. Our scripts create a checkout at
`c:\w\playwright-internal\playwright-internal\browser_patches\firefox\checkout`
1. One of the scripts in Firefox buildsystem tries to execute a command,
passing lots of absolute paths to various webidl's
1. The command fails due to restriction in (2)
**Problem**
Firefox build fails since checkout is deeply nested and hits max arg
size on windows.
**Solution**
This patch introduces a new variable `FF_CHECKOUT_PATH` that is
respected by all browser-related scripts. This way we'll be able
to checkout firefox to `c:\firefox` and avoid hitting long arguments
limit.
Instead of checking out the whole repository, we now do a shallow
clone.
We then gradually "unshallow" the clone, looking for the `BASE_REVISION`.
This should fix experimental mac-11 builder.
This patch moves FFMPEG building to buildbots:
- `ffmpeg-mac.zip` is built on Mac 10.14 machine
- `ffmpeg-win32.zip` and `ffmpeg-win64.zip` are cross-compiled on
Ubuntu 20.04 machine
All builds across the platforms share the same config:
- the same versions of `ffmpeg` and `libvpx`
- the same build configuration for both `ffmpeg` and `libvpx`
The config could be found in the `//browser_patches/ffmpeg/CONFIG.sh`.
The builds will be then copied manually and committed to the git
repository.
Relates #3258
After a chat with @aslushnikov we add this in two iterations. The first one (this PR) is about scheduled runs for testing the latest tip-of-tree version of the browsers daily and the next PR is about opening an automated PRs once its passing (not sure if its worth to add for failing too) or sending Telegram/Slack notifications.
Current status is that Firefox (around 2 hours) and WebKit (around 3-4 hours) works.
Known issues which I fix before we merge:
- ~~Changes in `test/base.fixture.ts` will get extracted in #3453~~
Feel free to review, current blockers are before we can merge:
- ~~#3453~~
- potential git clone optimisation by aslushnikov
Currently, it might happen that two different patches clash for the
same build number for the browsers. In this case, authors might
not even know that they need to rebaseline.
This patch starts adding a second line to `BUILD_NUMBER` files - the
signature and date of the `BUILD_NUMBER` change. These are guaranteed
to clash, so it should not be possible to land patches without
re-baselining them.
This changes `export.sh` to export diffs instead of patches.
`export.sh` now does not touch working directory, thus not
triggering clean builds and not intefering with an on-going
build.
