The bare-bones `debian` distribution we use for testing doesn't have
`ps`. This patch switches to reading `/proc` file system directly on
Linux instead of relying on `ps`.
Performance measurements for the 20000 active processes on Debian Docker
container, tested on my M1 Max Mac:
- the `ps -eo pid,ppid,pgid` call + parsing takes 293ms
- the manual synchronous `/proc` traversal + parsing takes 326ms
So this is ~10% perf penalty.
Drive-by: rename `pgid` into `pgrp` so that it stands out from `pid`
(process ID) and `ppid` (parent process ID).
This patch:
- changes the `childProcess` fixture to reliably SIGKILL all descendants
(children and grand-children, regardless of their process group).
This is achieved using the `ps` command to build the process tree, and
then send
`SIGKILL` to the descendant process groups.
- changes the `runCLI` fixture to **not** auto-close codegen by default;
the `childProcess` fixture will clean up all processes. This makes
sure that all `runCLI.waitFor()` commands actually wait until the
necessary
output.
- for a handful of tests that do actually want to auto-close codegen,
introduce an optional `autoCloseWhen` flag for the `runCLI` fixture
that makes sure to close the codegen once a certain output was reached.
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.
feat: support experimental doc entries
- Params/options/members are marked as experimental in the docs.
- `experimental.d.ts` is generated that contains all types and
includes experimental features.
- `experimental.d.ts` is references in our tests so that we
can test experimental features.
- `fonts` option is restored as experimental.
