This commit adds a method of `Symbol.dispose` to the object returned
from `Deno.createHttpClient`, so we can make use of [explicit resource
management](https://github.com/tc39/proposal-explicit-resource-management)
by declaring it with `using`.
Switch `ext/fetch` over to `resourceForReadableStream` to simplify and
unify implementation with `ext/serve`. This allows us to work in Rust
with resources only.
Two additional changes made to `resourceForReadableStream` were
required:
- Add an optional length to `resourceForReadableStream` which translates
to `size_hint`
- Fix a bug where writing to a closed stream that was full would panic
This helps reduce flakes where a test starts an HTTP server and makes a
request using fetch, then shuts down the server, then starting a new
test with a new server, but the connection pool still has a "not quite
closed yet" connection to the old server, and a new request to the new
server gets sent on the closed connection, which obviously errors out.
This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
This runs our `js_unit_tests` and `node_unit_tests` in parallel, one
rust test per JS unit test file. Some of our JS tests don't like running
in parallel due to port requirements, so this also makes those use a
specific port-per-file. This does not attempt to make the node-compat
tests work.
Right now an error in a request body stream causes an uncatchable
global promise rejection. This PR fixes this to instead propagate the
error correctly into the promise returned from `fetch`.
It additionally fixes errored readable stream bodies being treated as
successfully completed bodies by Rust.
Previously the inner request object of the original and the new request
were the same, causing the requests to be entangled and mutable changes
to one to be visible to the other. This fixes that.
This commit introduces two new buffer wrapper types to `deno_core`. The
main benefit of these new wrappers is that they can wrap a number of
different underlying buffer types. This allows for a more flexible read
and write API on resources that will require less copying of data
between different buffer representations.
- `BufView` is a read-only view onto a buffer. It can be backed by
`ZeroCopyBuf`, `Vec<u8>`, and `bytes::Bytes`.
- `BufViewMut` is a read-write view onto a buffer. It can be cheaply
converted into a `BufView`. It can be backed by `ZeroCopyBuf` or
`Vec<u8>`.
Both new buffer views have a cursor. This means that the start point of
the view can be constrained to write / read from just a slice of the
view. Only the start point of the slice can be adjusted. The end point
is fixed. To adjust the end point, the underlying buffer needs to be
truncated.
Readable resources have been changed to better cater to resources that
do not support BYOB reads. The basic `read` method now returns a
`BufView` instead of taking a `ZeroCopyBuf` to fill. This allows the
operation to return buffers that the resource has already allocated,
instead of forcing the caller to allocate the buffer. BYOB reads are
still very useful for resources that support them, so a new `read_byob`
method has been added that takes a `BufViewMut` to fill. `op_read`
attempts to use `read_byob` if the resource supports it, which falls
back to `read` and performs an additional copy if it does not. For
Rust->JS reads this change should have no impact, but for Rust->Rust
reads, this allows the caller to avoid an additional copy in many
scenarios. This combined with the support for `BufView` to be backed by
`bytes::Bytes` allows us to avoid one data copy when piping from a
`fetch` response into an `ext/http` response.
Writable resources have been changed to take a `BufView` instead of a
`ZeroCopyBuf` as an argument. This allows for less copying of data in
certain scenarios, as described above. Additionally a new
`Resource::write_all` method has been added that takes a `BufView` and
continually attempts to write the resource until the entire buffer has
been written. Certain resources like files can override this method to
provide a more efficient `write_all` implementation.
This commit adds a fast path to `Request` and `Response` that
make consuming request bodies much faster when using `Body#text`,
`Body#arrayBuffer`, and `Body#blob`, if the body is a FastStream.
Because the response bodies for `fetch` are FastStream, this speeds up
consuming `fetch` response bodies significantly.
Previously if a user specified a content-length header for an POST
request without a body, the request would contain two `content-length`
headers. One added by us, and one added by the user.
This commit ignores all content-length headers coming from the user,
because we need to have the sole authority on the content-length because
we transmit the body.
`fetch()` and client-side websocket used to support HTTP/2, but this
regressed in #11491. This patch reenables it by explicitly adding `h2`
and `http/1.1` to the list of ALPN protocols on the HTTP and websocket
clients.
This adds support for using in memory CA certificates for
`Deno.startTLS`, `Deno.connectTLS` and `Deno.createHttpClient`.
`certFile` is deprecated in `startTls` and `connectTls`, and removed
from `Deno.createHttpClient`.
