Fetching of local files, added in #12545, returns a response with no
headers, including the `Content-Type` header. This currently makes it
not work with the WebAssembly streaming APIs, which require the response
to have a content type of `application/wasm`.
Since the only way to obtain a `Response` object with a non-empty `url`
field is via `fetch()`, this change changes the content type requirement
to only apply to responses whose url has the `file:` scheme.
This allows resources to be "streams" by implementing read/write/shutdown. These streams are implicit since their nature (read/write/duplex) isn't known until called, but we could easily add another method to explicitly tag resources as streams.
`op_read/op_write/op_shutdown` are now builtin ops provided by `deno_core`
Note: this current implementation is simple & straightforward but it results in an additional alloc per read/write call
Closes #12556
The Web IDL conversion to `BufferSource` and similar types shouldn't
check whether the buffer is detached.
In the case of `TextDecoder`, our implementation would still throw after
the Web IDL conversions because we're creating a new `Uint8Array` from
the buffer source's buffer, which throws if it's detached. This change
also fixes this bug.
The implementation of `TextDecoder` had a bug where it was copying the
input data in every case. This change removes that copy in
non-`SharedArrayBuffer` cases.
Since passing a shared buffer source to Rust would fail, this copy of
the input data was making `TextDecoder` work in cases where the input
is shared. In order to avoid a breaking change, the copy is retained in
those cases.
Closes #11882
BREAKING CHANGE: Previously when `--location` was set, the unique storage key was derived from the the URL of the location instead of just the origin. This change correctly uses just the origin. This may cause previously persisted storage to change its key and data to not be available with the same location as before.
A `handshake()` method was added that returns when the TLS handshake is
complete. The `TlsListener` and `TlsConn` interfaces were added to
accomodate this new method.
Closes: #11759.
`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.
A bug was fixed that could cause a hang when a method was
called on a TlsConn object that had thrown an exception earlier.
Additionally, a bug was fixed that caused TlsConn.write() to not
completely flush large buffers (>64kB) to the socket.
The public `TlsConn.handshake()` API is scheduled for inclusion in the
next minor release. See https://github.com/denoland/deno/pull/12467.
Currently all async ops are polled lazily, which means that op
initialization code is postponed until control is yielded to the event
loop. This has some weird consequences, e.g.
```js
let listener = Deno.listen(...);
let conn_promise = listener.accept();
listener.close();
// `BadResource` is thrown. A reasonable error would be `Interrupted`.
let conn = await conn_promise;
```
JavaScript promises are expected to be eagerly evaluated. This patch
makes ops actually do that.
GET/HEAD requests can't have bodies according to `fetch` spec. This
commit changes the HTTP server to hide request bodies for requests with
GET or HEAD methods.
WebAssembly modules compiled through `WebAssembly.compile()` and similar
non-streaming APIs don't have a URL associated to them, because they
have been compiled from a buffer source. In stack traces, V8 will use
a URL such as `wasm://wasm/d1c677ea`, with a hash of the module.
However, wasm modules compiled through streaming APIs, like
`WebAssembly.compileStreaming()`, do have a known URL, which can be
obtained from the `Response` object passed into the streaming APIs. And
as per the developer-facing display conventions in the WebAssembly
Web API spec, this URL should be used in stack traces. This change
implements that.
This commit adds support for passing buffer arguments across
FFI boundary.

These are confusing. They say they are "for users that don't care about
permissions", but that isn't correct. `NoTimersPermissions` disables
permissions instead of enabling them.
I would argue that implementors should decide what permissions they want
themselves, and not take our opinionated permissions struct.
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`.
