Adding HTTP & websocket awareness to the TCP server.
HTTP server handles `GET /json/version` and websocket upgrade requests.
Conceptually, websocket handling is the same code as before, but receiving
data will parse the websocket frames and writing data will wrap it in
a websocket frame.
The previous `Ctx` was split into a `Server` and a `Client`. This was
largely done to make it easy to write unit tests, since the `Client` is
a generic, all its dependencies (i.e. the server) can be mocked out. This
also makes it a bit nicer to know if there is or isn't a client (via the
server's client optional).
Added a MemoryPool for the Send object (I thought that was a nice touch!)
Removed MacOS hack on accept/conn completion usage.
Known issues:
- When framing an outgoing message, the entire message has to be duped. This
is no worse than how it was before, but it should be possible to eliminate
this in the future. Probably not part of this PR.
- Websocket parsing will reject continuation frames. I don't know of a single
client that will send a fragmented message (websocket has its own
message fragmentation), but we should probably still support this just in
case.
- I don't think the receive, timeout and close completions can safely be
re-used like we're doing. I believe they need to be associated with a specific
client socket.
- A new connection creates a new browser session. I think this is right (??),
but for the very first, we're throwing out a perfectly usable session. I'm
thinking this might be a change to how Browser/Sessions work.
- zig build test won't compile. This branch reproduces the issue with none
of these changes:
https://github.com/karlseguin/browser/tree/broken_test_build
(or, as a diff to main):
https://github.com/lightpanda-io/browser/compare/main...karlseguin:broken_test_build
Preserves all existing behavior (i.e. make test and zig build test are not
changed in any way).
The new 'unittest' only runs unit tests and is fast to build. It takes ~1.7 to
build unittest, vs ~11.09 to build test. This is really the main goal, and
hopefully any unit test which are (a) fast and (b) don't impact build times
will be run here.
The test runner is based on:
https://gist.github.com/karlseguin/c6bea5b35e4e8d26af6f81c22cb5d76b
It allow filtering, i.e. `make unittest F="parse query dup"`.
'unittest' does memory leak detection when tests use std.testing.allocator.
Fixed a memory leak in url/query which was detected/reported with by the new
'unittest'.
In order to avoid having 3 src/test_xyx.zig files, I merged the existing
test_runner.zig and run_tests.zig into a single main_tests.zig. (this change
is superfluous, but I thought it was cleaner this way. Happy to revert this).
By default mimalloc is built to override default allocation functions.
So it is used also by v8.
This change avoid the mimalloc override to keep the native stdlib
functions.
