This commit adds following fields to "Deno.TestContext" interface:
- name
- origin
- parent
These are prerequisites for supporting snapshot functionality in
"std/testing".
`handleWasmStreaming` is the function that provides the binding with
the `fetch` API needed for `WebAssembly.instantiateStreaming()` and
`WebAssembly.compileStreaming()`. When I implemented it in #11200, I
thought V8 was calling these functions with the argument of the
`WebAssembly` streaming functions, without doing any resolving, and so
`handleWasmStreaming` awaits for the parameter to resolve. However,
as discovered in
https://github.com/denoland/deno/issues/13917#issuecomment-1065805565,
V8 does in fact resolve the parameter if it's a promise (and handles
rejections arising from that).
This change removes the `async` IIFE inside `handleWasmStreaming`,
letting initial errors be handled synchronously (which will however
not throw synchronously from the `WebAssembly` namespace functions).
Awaiting is still necessary for reading the bytes of the response,
though, and so there is an `async` IIFE for that.
This commit adds "Deno.upgradeHttp" API, which
allows to "hijack" connection and switch protocols, to eg.
implement WebSocket required for Node compat.

In the implementation of structured serialization in
`Deno.core.serialize`, whenever there is a serialization error, an
exception will be thrown with the message "Failed to serialize
response", even though V8 provides a message to use in such cases.
This change instead throws an exception with the V8-provided message,
if there is one.
This commit improves the error messages for the `deno test` async op
sanitizer. It does this in two ways:
- it uses handwritten error messages for each op that could be leaking
- it includes traces showing where each op was started
This "async op tracing" functionality is a new feature in deno_core.
It likely has a significant performance impact, which is why it is only
enabled in tests.
This commit adds `readable` and `writable` properties to `Deno.File` and
`Deno.Conn`. This makes it very simple to use files and network sockets
with fetch or the native HTTP server.
V8 has supported `Intl.ListFormat` since version 7.2, but TypeScript doesn't
have typings for it yet. This PR manually adds those typings, copying them from
microsoft/TypeScript#47254.
std/http/server knows how to handle "Listener has been closed"
exceptions but not "operation canceled" errors.
Make "unix" listen sockets throw the same exception as "tcp" listen
sockets when the socket is closed and has a pending accept operation.
There is still a discrepancy when multiple accept requests are posted
but that's probably a less visible issue and something for another day.
Fixes #13033
This commit adds support for exporting RSA JWKs in the Web Crypto API.
It also does some minor fixes for RSA JWK imports.

This change also makes the timers implementation closer to the spec, and
sets up the stage to implement AbortSignal.timeout() (whatwg/dom#1032).
Fixes #8965
Fixes #10974
Fixes #11398
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
Closes #11826
**BREAKING CHANGE** this behaviour was disable when introduced in Deno 1.14/TypeScript 4.4. It will highlight code that unsafely handles variables that are caught, and will cause type errors in unsafe code.
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.
On OS X, the watcher sometimes witnesses the creation of it's own root
directory. Creating that directory using a sync op instead of an async
op sidesteps the issue.
