This commit removes the libuv pollyfills introduced with Node-API
support.
It is too much Node-specific. Most Node-API modules that depend on libuv
are already giving up the benefits of Node-API. We should rather
encourage modules to use `ThreadSafeFunction` or `AsyncWork` to
interface with the event loop.
Relevant discussion a few months ago:

This commit changes "ProcState" to store "file_fetcher" field in an "Arc",
allowing it to be preserved between restarts and thus keeping the state
alive between the restarts. File watchers for "deno test" and "deno bench"
now reset "ProcState" between restarts.
This commit changes signature of "deno_core::ModuleLoader::resolve" to pass
an enum indicating whether or not we're resolving a specifier for dynamic import.
Additionally "CliModuleLoader" was changes to store both "parent permissions" (or
"root permissions") as well as "dynamic permissions" that allow to check for permissions
in top-level module load an dynamic imports.
Then all code paths that have anything to do with Node/npm compat are now checking
for permissions which are passed from module loader instance associated with given
worker.
This PR updates the name used in `clap::Arg::value_name` for the
`--inspect*` flags from `HOST:PORT` to `HOST_AND_PORT` because the
former causes an arguments error when using shell completions in the
`zsh` shell.
Adds support for passing and returning structs as buffers to FFI. This does not implement fastapi support for structs. Needed for certain system APIs such as AppKit on macOS.
Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.
If an optional peer dependency entry previously wasn't resolved and it's
now being resolved, then it will add it as if it were a dependency of
the previously resolved package instead of creating a new "copy package"
(seems to be what npm and pnpm does).
Closes #17240
Previously, `Deno.permissions.[revoke|request]()` wouldn't correctly
process the `path: URL` when `name` was `ffi`. This change fixes that
behaviour and adds a new function, `formDescriptor()`, to ensure `URL`
arguments are consistently handled across
`Deno.permissions.[query|revoke|request]()`.
This commit fixes "Add all missing imports" quick fix; before
it was replacing all occurrences with the same specifier. Now
every line returned from TSC is processed individually.
This commit adds "Deno.Conn.ref()" and "Deno.Conn.unref()" methods.
These methods can be used to make connection block or not block the
event loop from finishing. Refing/unrefing only influences "read"
operations - ie. scheduling writes to a connection _do_ keep event
loop alive.

This commit fixes handling of rejected promises in dynamic imports
evaluation.
Previously we were running callbacks for next ticks and macrotasks
_before_ polling
dynamic imports and checked for unhandled rejections immediately after.
This is wrong,
as `unhandledrejection` event is dispatched and its callbacks are run as
macrotasks.
This commit changes order of actions performed by the event loop to
following:
- poll async ops
- poll dynamic imports
- run next tick callbacks
- run macrotask callbacks
- check for unhandled promise rejections
This commit fixes formatting of JSError with "errors" property. Before this
commit all instances of "Error" were treated as if they were "AggregateError"
if they had "errors" property. After this commit only actual instances of
"AggregateError" are formatted in such a way, while instances of "Error"
that have "errors" property are formatted without showing details of "errors".
Previously, errored streaming response bodies did not cause the HTTP
stream to be aborted. It instead caused the stream to be closed gracefully,
which had the result that the client could not detect the difference
between a successful response and an errored response.
This commit fixes the issue by aborting the stream on error.
This PR adds the concept of a global `DrawThread`, which can receive
multiple renderers to draw information on the screen (note: the
underlying thread is released back to tokio when it's not rendering). It
also separates the concept of progress bars from the existing "draw
thread". This makes it trivial for us to do stuff like show permission
prompts and progress bars at the same time in the future.
The reason this is global is because the process' tty stderr is also a
global concept.
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.
The output of `init` are commands, so this should be treated as a "Shell
script". In Shell script, comments must start with `#`, not `//`. (This
also makes the commands example easier to be copied to somewhere.)
This commit changes implementation of "Deno.memoryUsage()" to return
correct value for "rss" field. To do that we implement a specialized function
per os to retrieve this information.
In our `require()` implementation we use a special logic to resolve
"base path" when looking for matching packages, however this logic
is in contradiction to what needs to happen if there's a local
"node_modules"
directory used. This commit changes require implementation to be aware
if we're running off of global node modules cache or a local one.
This commit adds new "--inspect-wait" flag which works similarly
to "--inspect-brk" in that it waits for inspector session to be
established before running code. However it doesn't break on the first
statement of user code, but instead runs it as soon as a session
is established.
This commit removes three unstable Deno APIs:
- "Deno.spawn()"
- "Deno.spawnSync()"
- "Deno.spawnChild()"
These APIs were replaced by a unified "Deno.Command" API.
This allows the user to completely opt out from the lock file or rename
it without having to use `--no-lock` and/or `--lock` in all commands.
## Don’t Use Lock File
```json
{
"lock": false
}
```
## Use Lock File With a Different Name
```json
{
"lock": "deno2.lock"
}
```
The CLI args `--no-lock` and `--lock` will always override what is in
the config file.

This commit changes "deno repl" command to run with no permissions by
default and accept "--allow-*" flags.
This change is dictated by the fact that currently there is no way to
run REPL with limited permissions. Technically it's a breaking
change in the CLI command, but there's agreement in the team
that it has merit and it's a good solution.
Running just "deno" command still starts the REPL with full permissions
allowed, but now a banner is printed to inform users about that:
We currently only do this for fmt. This makes it so they're excluded by
default, but you can still opt into these directories by explicitly
specifying them.
This commit adds "InspectorTester" struct which is used in
inspector tests - it encapsulated various functionalities that
we need (like reading/writing to WebSocket), but also adds
better error handling which should help with debugging flaky
tests.
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.
Currently runtime exception are only displayed at the program end in
terminal, which makes it only a partial fix, as a full fix requires
https://github.com/denoland/rusty_v8/pull/1149 which adds new bindings
to the inspector that allows to notify it about thrown exceptions.
This will be handled in a follow up commit.
This commit completely rewrites inspector session polling.
Until now, there was a single function responsible for polling inspector
sessions which could have been called when polling the "JsRuntime"
as well as from internal inspector functions. There are some cases
where it's required to have reentrant polling of sessions (eg. when
"debugger" statement is run) which should be blocking until inspector
sends appropriate message to continue execution. This was not possible
before, because polling of sessions didn't have reentry ability.
As a consequence, session polling was split into two separate functions:
a) one to be used when polling from async context (on each tick of event
loop in "JsRuntime")
b) one to be used when polling synchronously and potentially blocking
(used by various inspector methods).
There are further cleanups and simplifications to be made in inspector
code, but this rewrite solves the problem at hand (being able to
evaluate
"debugger" JS statement and continue inspector functionality).

Since "Deno.spawn()", "Deno.spawnSync()" and "Deno.spawnChild"
are getting deprecated, this commits rewrites all tests and utilities to
use "Deno.Command" API instead.
