`x-playwright-debug-log: value` headers are printed to `pw:browser`
debug log.
`x-playwright-attachment: name=value` headers are attached to each test.
Fixes#21619.
This reverts commit 303c5998f8.
Reason for revert: I tried enabling `ssim-cie94` by default on
ionic-framework test suite, and it proves to be overly strict for their
usecase.
The option defines a comparator to be used to compare images.
Possible values are `"pixelmatch"` and `"ssim-cie94"`.
Note: This reverts commit 8167f8bf54.
- When disposing recursively, only the root dispatcher received
`_dispose()` call, while some dispatchers need `_onDispose()` to clean
things up.
- When reusing the context, pages should be notified with `_onClose()`
so that all client-side waiting promises could reject.
Fixes#19216.
This patch implements a new mode of network tethering for Playwright
server & its clients.
With this patch:
- playwright server could be launched with the
`--browser-proxy-mode=tether` flag to engage in the new mode
- a new type of client, "Network Tethering Client" can connect to the
server to provide network traffic to the browsers
- all clients that connect to the server with the `x-playwright-proxy:
*` header will get traffic from the "Network Tethering Client"
This patch also adds an environment variable
`PW_OWNED_BY_TETHER_CLIENT`. With this env, playwright server will
auto-close when the network tethering client disconnects. It will also
auto-close if the network client does not connect to the server in the
first 10 seconds of the server existence. This way we can ensure that
`npx playwright docker start` blocks terminal & controls the lifetime of
the started container.
Instead of requiring all frames in the subtree to receive a particular
event, we rely on the browser's definition of load and DOMContentLoaded.
This changes logic in a few edge cases:
- Some browsers do not emit load event upon window.stop() at all.
- DOMContentLoaded does not wait for subframes, so they might not be
ready when passing `{ waitUntil: 'domcontentloaded' }`.
`networkidle` preserves the old logic.
