The return type checking for `"function"` type FFI values was incorrect
and presumed that functions were still being registered as objects
containing a "function" key.
While here, I also removed the whole return type checking logic as it
was needed for optionally creating BigInts on return when needed, but
serde_v8 does this automatically now (I think).
This PR fixes invalid header parsing which is flaky because `g` flag is
being used in the regex, which keeps track of `lastIndex`
```javascript
try {
new Headers([["x", "\u0000x"]]); // error
} catch(e) {}
new Headers([["x", "\u0000x"]]); // no error
```
This issue affects `Response` & `Request` constructors as well
This commit adds a new op_write_all to core that allows writing an
entire chunk in a single async op call. Internally this calls
`Resource::write_all`.
The `writableStreamForRid` has been moved to `06_streams.js` now, and
uses this new op. Various other code paths now also use this new op.
Closes#16227
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.
Mea culpa. Back when I re-introduced parameter and return value types to
FFI callbacks I failed to properly account for the change in match arm
logic. As a result, usize and isize parameters in FFI callbacks
currently enter the branch meant for void only.
This PR changes the match arms to all be explicit, making sure that void
is the only arm marked unreachable and that it stays that way.
The current location was causing failures during v1.26.1 publication.

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.
We can use Resource::read_return & op_read instead. This allows HTTP
request bodies to participate in FastStream.
To make this work, `readableStreamForRid` required a change to allow non
auto-closing resources to be handled. This required some minor changes
in our FastStream paths in ext/http and ext/flash.
