Use `Map` to cache validated HTTP headers. Cache
has a capacity of 4096 elements and it's cleared
once that capacity is reached.
In `preactssr` benchmark it lowers the time spent
when adding headers from 180ms to 2.5ms.
Remove `ExtensionFileSourceCode::LoadedFromFsDuringSnapshot` and feature
`include_js_for_snapshotting` since they leak paths that are only
applicable in this repo to embedders. Replace with feature
`exclude_js_sources`. Additionally the feature
`force_include_js_sources` allows negating it, if both features are set.
We need both of these because features are additive and there must be a
way of force including sources for snapshot creation while still having
the `exclude_js_sources` feature. `force_include_js_sources` is only set
for build deps, so sources are still excluded from the final binary.
You can also specify `force_include_js_sources` on any extension to
override the above features for that extension. Towards #19398.
But there was still the snapshot-from-snapshot situation where code
could be executed twice, I addressed that by making `mod_evaluate()` and
scripts like `core/01_core.js` behave idempotently. This allowed
unifying `ext::init_ops()` and `ext::init_ops_and_esm()` into
`ext::init()`.
Reduce the GC pressure from the websocket event method by splitting it
into an event getter and a buffer getter.

This commit migrates "deno_core" from using "FuturesUnordered" to
"tokio::task::JoinSet". This makes every op to be a separate Tokio task
and should unlock better utilization of kqueue/epoll.
There were two quirks added to this PR:
- because of the fact that "JoinSet" immediately polls spawn tasks,
op sanitizers can give false positives in some cases, this was
alleviated by polling event loop once before running a test with
"deno test", which gives canceled ops an opportunity to settle
- "JsRuntimeState::waker" was moved to "OpState::waker" so that FFI
API can still use threadsafe functions - without this change the
registered wakers were wrong as they would not wake up the
whole "JsRuntime" but the task associated with an op

Using `deopt-explorer` I found that a bunch of fields on `WebSocket`
class were polymorphic.
Fortunately it was enough to initialize them to `undefined`
to fix the problem.
No need to go through the async machinery for `send(String | Buffer)` --
we can fire and forget, and then route any send errors into the async
call we're already making (`op_ws_next_event`).

Related issue: https://github.com/denoland/deno/issues/19358.
This is a regression that seems to have been introduced in
https://github.com/denoland/deno/pull/18905. It looks to have been a
performance optimization.
The issue is probably easiest described with some code:
```ts
const target = new EventTarget();
const event = new Event("foo");
target.addEventListener("foo", () => {
console.log('base');
target.addEventListener("foo", () => {
console.log('nested');
});
});
target.dispatchEvent(event);
```
Essentially, the second event listener is being attached while the `foo`
event is still being dispatched. It should then not fire that second
event listener, but Deno currently does.
`rusqlite` does not support async operations; with this PR SQLite
operations will run through `spawn_blocking` to ensure that the event
loop does not get blocked.
There is still only a single SQLite connection. So all operations will
do an async wait on the connection. In the future we can add a
connection pool if needed.
This PR attempts to resolve the first item on the list from
https://github.com/denoland/deno/issues/19330 which is about using a
flat list of interleaved key/value pairs, instead of a nested array of
tuples.
I can tackle some more if you can provide a quick example of using raw
v8 arrays, cc @mmastrac

Internally, `node-tap` spawns a child process with `stdio: [0, 1, 2]`.
Whilst we don't support passing fd numbers as an argument so far, it
turns out that `[0, 1, 2]` is equivalent to `"inherit"` which we already
support. See: https://nodejs.org/api/child_process.html#optionsstdio
Mapping it to `"inherit"` is fine for us and gets us one step closer in
getting `node-tap` working. I'm now at the stage where already the
coverage table is shown 🎉

## WHY
ref: https://github.com/denoland/deno/issues/19165
Node's fs/promises includes a FileHandle class, but deno does not. The
open function in Node's fs/promises returns a FileHandle, which provides
an IO interface to the file. However, deno's open function returns a
resource id.
### deno
```js
> const fs = await import("node:fs/promises");
undefined
> const file3 = await fs.open("./README.md");
undefined
> file3
3
> file3.read
undefined
Node:
```
### Node
```js
> const fs = await import("fs/promises");
undefined
> const file3 = await fs.open("./tests/e2e_unit/testdata/file.txt");
undefined
> file3
FileHandle {
_events: [Object: null prototype] {},
_eventsCount: 0,
_maxListeners: undefined,
close: [Function: close],
[Symbol(kCapture)]: false,
[Symbol(kHandle)]: FileHandle {},
[Symbol(kFd)]: 24,
[Symbol(kRefs)]: 1,
[Symbol(kClosePromise)]: null
}
> file3.read
[Function: read]
```
To be compatible with Node, deno's open function should also return a
FileHandle.
## WHAT
I have implemented the first step in adding a FileHandle.
- Changed the return value of the open function to a FileHandle object
- Implemented the readFile method in FileHandle
- Add test code
## What to do next
This PR is the first step in adding a FileHandle, and there are things
that should be done next.
- Add functionality equivalent to Node's FileHandle to FileHandle
(currently there is only readFile)

For the first implementation of node:http2, we'll use the internal
version of `Deno.serve` which allows us to listen on a raw TCP
connection rather than a listener.
This is mostly a refactoring, and hooking up of `op_http_serve_on` that
was never previously exposed (but designed for this purpose).
This PR adds the missing `process.reallyExit()` method to node's
`process` object.
Was [pinged on
twitter](https://twitter.com/biwanczuk/status/1663326659787862017)
regarding running the `fastify` test suite in node. They use `node-tap`
which has been around arguably the longest of the test frameworks and
relies on a couple of old APIs. They have `signal-exit` as a dependency
which in turn [makes use of
`process.reallyExit()`](8fa7fc9a9c/src/index.ts (L19)).
That function cannot be found anywhere in their documentation, but
exists at runtime. See
6a6b3c5402/lib/internal/bootstrap/node.js (L172)
This doesn't yet make `node-tap` work, but gets us one step closer.
Under heavy load, we often have requests queued up that don't need an
async call to retrieve. We can use a fast path sync op to drain this set
of ready requests, and then fall back to the async op once we run out of
work.
This is a .5-1% bump in req/s on an M2 mac. About 90% of the handlers go
through this sync phase (based on a simple instrumentation that is not
included in this PR) and skip the async machinery entirely.
Rather than disallowing `ext:` resolution, clear the module map after
initializing extensions so extension modules are anonymized. This
operation is explicitly called in `deno_runtime`. Re-inject `node:`
specifiers into the module map after doing this.
Fixes #17717.
This commit fixes problem with loading N-API modules that use
the "old" way of registration (using "napi_module_register" API).
The slot was not cleared after loading modules, causing subsequent
calls that use the new way of registration (using
"napi_register_module_v1" API) to try and load the previous module.

This commit fixes emitting "unhandledrejection" event when there are
"node:" or "npm:" imports.
Before this commit the Node "unhandledRejection" event was emitted
using a regular listener for Web "unhandledrejection" event. This
listener was installed before any user listener had a chance to be
installed which effectively prevent emitting "unhandledrejection"
events to user code.
Closes https://github.com/denoland/deno/issues/16928
Noticed that we're checking more module paths than necessary. In
particular the module path array contains a couple of entries with a
duplicated `node_modules/node_modules` suffix.
```js
[
// ... more entries before here, where some also contain duplicate suffixes
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules/.deno/node_modules",
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules/node_modules", // <-- duplicate suffix
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules",
"/Users/marvinhagemeister/dev/node_modules",
"/Users/marvinhagemeister/node_modules",
"/Users/node_modules",
"/node_modules",
"/node_modules" // <-- duplicate entry
]
```
This was caused by a misunderstanding in how Rust's
[`Path::ends_with()`](https://doc.rust-lang.org/std/path/struct.Path.html#method.ends_with)
works. It's designed to match on whole path segments and the suffix
`/node_modules` is not that, except for the root entry. This meant that
our check for if the path already ended with `node_module` always
returned `false`. Removing the leading slash fixes that.
While we're at it, we can remove the last condition where we explicitly
added the root `/node_modules` entry since the while loop prior to that
takes care of it already.
This commit changes implementation of "setImmediate"
from "node:timers" module to 0ms timer that is never
clamped to 4ms no matter how many nested calls there are.
Closes https://github.com/denoland/deno/issues/19034
This commit changes the implementation of `ext/web` timers, by using
"op_void_async_deferred" for timeouts of 0ms.
0ms timeout is meant to be run at the end of the event loop tick and
currently Tokio timers that we use to back timeouts have at least 1ms
resolution. That means that 0ms timeout actually take >1ms. This
commit changes that and runs 0ms timeout at the end of the event
loop tick.
One consequence is that "unrefing" a 0ms timer will actually keep
the event loop alive (which I believe actually makes sense, the test
we had only worked because the timeout took more than 1ms).
Ref https://github.com/denoland/deno/issues/19034
This commit changes the return type of an unstable `Deno.serve()` API
to instead return a `Deno.Server` object that has a `finished` field.
This change is done in preparation to be able to ref/unref the HTTP
server.

This is a bit bare bones but gets `npm-run-all` working. For full stdio
compatibility with node more work is needed which is probably better
done in follow up PRs.
Fixes #19159
If a timer is requested with <=100ms resolution, request the high-res
timer. Since the default Windows timer period is 15ms, this means a
100ms timer could fire at 115ms (15% late). We assume that timers longer
than 100ms are a reasonable cutoff here.
The high-res timers on Windows are still limited. Unfortuntely this
means that our shortest duration 4ms timers can still be 25% late, but
without a more complex timer system or spinning on the clock itself,
we're somewhat bounded by the OS' scheduler itself.
This commit reimplements most of "node:http" client APIs using
"ext/fetch".
There is some duplicated code and two removed Node compat tests that
will be fixed in follow up PRs.

Fixes for various `Attemped to access invalid request` bugs (#19058,
#15427, #17213).
We did not wait for both a drop event and a completion event before
removing items from the slab table. This ensures that we do so.
In addition, the slab methods are refactored out into `slab.rs` for
maintainability.
Currently the `multipart/form-data` parser in
`Request.prototype.formData` and `Response.prototype.formData` decodes
non-ASCII filenames incorrectly, as if they were encoded in Latin-1
rather than UTF-8. This happens because the header section of each
`multipart/form-data` entry is decoded as Latin-1 in order to be parsed
with `Headers`, which only allows `ByteString`s, but the names and
filenames are never decoded correctly. This PR fixes this as a
post-processing step.
Note that the `multipart/form-data` parsing for this APIs in the Fetch
spec is very much underspecified, and it does not specify that names and
filenames must be decoded as UTF-8. However, it does require that the
bodies of non-`File` entries are decoded as UTF-8, and in browsers,
names and filenames always use the same encoding as the body.
Closes #19142.
This commit shams "performance.markResourceTiming" API by
using a noop function. It is done to provide compatibility with
"npm:undici" package. We should look into actually implementing
this API properly, but I wanted to unblock support for "undici" and
"astro" for now.

Merges `op_http_upgrade_next` and `op_ws_server_create`, significantly
simplifying websocket construction in ext/http (next), and removing one
JS -> Rust call. Also WS server now doesn't bypass
`HttpPropertyExtractor`.
Improve abstractions around listeners to support listener + connection
network stream combinations not previously possible (for example a
listener exposed as a Tcp, creating Unix network streams).
Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This PR ensures that node's `worker_threads` module exports
`MessageChannel`, `MessagePort` and the `BroadcastChannel` API. Fixing
these won't make `esbuild` work, but brings us one step closer 🎉
Fixes #19028 .
This is the initial support for npm and node specifiers in `deno
compile`. The npm packages are included in the binary and read from it via
a virtual file system. This also supports the `--node-modules-dir` flag,
dependencies specified in a package.json, and npm binary commands (ex.
`deno compile --unstable npm:cowsay`)
Closes #16632
`Content-Encoding: gzip` support for `Deno.serve`. This doesn't support
Brotli (`br`) yet, however it should not be difficult to add. Heuristics
for compression are modelled after those in `Deno.serveHttp`.
Tests are provided to ensure that the gzip compression is correct. We
chunk a number of different streams (zeros, hard-to-compress data,
already-gzipped data) in a number of different ways (regular, random,
large/small, small/large).
This now allows circular imports across extensions.
Instead of load + eval of all ESM files in declaration order, all files
are only loaded. Eval is done recursively by V8, only evaluating
files that are listed in `Extension::esm_entry_point` fields.

Fixes #16699 and #18960 by ensuring that we release our HTTP
`spawn_local` tasks when the HTTP resource is dropped.
Because our cancel handle was being projected from the resource via
`RcMap`, the resource was never `Drop`ped. By splitting the handle out
into its own `Rc`, we can avoid keeping the resource alive and let it
drop to cancel everything.
1. Boxed `File` and `FileSystem` to allow more easily passing this
through the CLI code (as shown within this pr).
2. `StdFileResource` is now `FileResource`. `FileResource` now contains
an `Rc<dyn File>`.

This removes the tty stuff that's hanging on the file resources and
instead stores them in a separate `TtyModeStore`. Although this will
cause the tty store items to not be removed when the resource is
removed, I think this is ok to do because there will be a small number
of resources this is every done with and usually those resources won't
ever be closed.
This commit changes how paths for npm packages are handled,
by canonicalizing them when resolving. This is done so that instead
of returning

(which is a symlink) we "node_modules/<dep>@<dep_version>/index.js.

2 fixes related to sync fs:
* update the 2 sync methods on `Resource` trait to take `Rc<Self>`
(consistent with other methods)
* fix a bug in `StdFileResource::with_inner_and_metadata`, which
currently can trigger a panic if a sync method is called on a file with
a pending async operation. This could happen in the code path where
`File::try_clone`
[fails](39ece1fe0d/ext/io/lib.rs (L485-L489)).
Towards https://github.com/denoland/deno/issues/18455
`safe`, `add` and `rem` options are not implemented because there is no
rust crate that provides this functionality (except rust-openssl maybe)
and its just not clear if this API is used widely.
- No need to wrap buffer in a `new DataView()`
- Deferred ops are still eagerly polled, but resolved on the next
tick of the event loop, we don't want them to be eagerly polled
- Using "core.opAsync"/"core.opAsync2" incurs additional cost
of looking up these functions on each call. Similarly with "ops.*"

This commit fixes "node:http" API to properly handle "upgrade"
requests and thus marking Vite work again.
This is done by migrating back to "Deno.serve()" and internal
"upgradeHttpRaw" APIs for "node:http" module polyfill.
We can make `NodePermissions` rely on interior mutability (which the
`PermissionsContainer` is already doing) in order to not have to clone
everything all the time. This also reduces the chance of an accidental
`borrow` while `borrrow_mut`.
This implements HTTP/2 prior-knowledge connections, allowing clients to
request HTTP/2 over plaintext or TLS-without-ALPN connections. If a
client requests a specific protocol via ALPN (`h2` or `http/1.1`),
however, the protocol is forced and must be used.
We were indeterministically including packages in the top level
`node_modules/` folder when using a local node_modules directory. This
change aligns with pnpm and only includes top level packages in this
folder. This should be faster for initializing the folder, but may
expose issues in packages that reference other packages not defined in
their dependencies. That said, the behaviour previously was previously
broken.
This has exposed a bug in the require implementation where it doesn't
find a package (which is the main underlying issue here). There is a
failing test already for this in the test suite after this change.
Closes #18822

This is a rewrite of the `Deno.serve` API to live on top of hyper
1.0-rc3. The code should be more maintainable long-term, and avoids some
of the slower mpsc patterns that made the older code less efficient than
it could have been.
Missing features:
- `upgradeHttp` and `upgradeHttpRaw` (`upgradeWebSocket` is available,
however).
- Automatic compression is unavailable on responses.
This is just a straight refactor and I didn't do any cleanup in
ext/node. After this PR we can start to clean it up and make things
private that don't need to be public anymore.

Private and public key encoding depend on `KeyObject#export` which is
not implemented. I've also skipped ED448 and X448 since we need a crate
for that in WebCrypto too.
This function was inherently racy which showed on slow machines -
the connect future started before the spawned task was first polled.
This change makes it so we're already accepting a connection when
the connect future is first polled.
- preserve referential invariants (e.g. path.posix === posix)
- remove glob and separator exports
- save removal of fromFileUrl and toFileUrl for a different PR as that
refactor is more involved
- addresses #18177
This commit removes the dependencies on `deno_core` for the Fs trait.
This allows to move the trait into a different crate that does not
depend on core in the limit.
This adds a new `bounds` field to `deno_core::extension!` that expands
to `where` clauses on the generated code. This allows to add bounds to
the extension parameters, such as `Fs::File: Resource`.
Fixes https://github.com/denoland/deno/issues/18700
Timeline of the events that lead to the bug.
1. WebSocket handshake complete
2. Server on `read_frame` holding an AsyncRefCell borrow of the
WebSocket stream.
3. Client sends a TXT frame after a some time
4. Server recieves the frame and goes back to `read_frame`.
5. After some time, Server starts a `write_frame` but `read_frame` is
still holding a borrow!
^--- Locked. read_frame needs to complete so we can resume the write.
This commit changes all writes to directly borrow the
`fastwebsocket::WebSocket` resource under the assumption that it won't
affect ongoing reads.
- bump deps: the newest `lazy-regex` need newer `oncecell` and
`regex`
- reduce `unwrap`
- remove dep `lazy_static`
- make more regex cached

This commit abstracts out the specifics of the underlying system calls
FS operations behind a new `FileSystem` and `File` trait in the
`ext/fs` extension.
This allows other embedders to re-use ext/fs, but substituting in a
different FS backend.
This is likely not the final form of these traits. Eventually they will
be entirely `deno_core::Resource` agnostic, and will live in a seperate
crate.

This commit adds op_read_sync and op_write_sync to core. These ops are
similar to op_read and op_write, but they are synchronous. Just like the
async ops, they operate on generic `deno_core::Resource` objects. These
now have new `read_byob_sync` and `write_sync` methods, with default
implementations throwing "NotSupported" errors, just like the async
counterparts.
There are no `write_all` or `read` equivalents, because the
optimizations they unlock are not useful in synchronous contexts.
This is a follow-on to the earlier work in reducing string copies,
mainly focused on ensuring that ASCII strings are easy to provide to the
JS runtime.
While we are replacing a 16-byte reference in a number of places with a
24-byte structure (measured via `std::mem::size_of`), the reduction in
copies wins out over the additional size of the arguments passed into
functions.
Benchmarking shows approximately the same if not slightly less wallclock
time/instructions retired, but I believe this continues to open up
further refactoring opportunities.

This commit updates the `Deno.Kv` API to return the new commited
versionstamp for the mutated data from `db.set` and `ao.commit`. This is
returned in the form of a `Deno.KvCommitResult` object that has a
`versionstamp` property.
This reverts commit a3529d0232.
This change made debugging Node tests very hard - `AssertionError` is
now printed as `[Circular *1]` giving no visibility what failed.
We need to align two implementations together and remove this one then.
This commit adds associated type to "NodeEnv" trait, called "Fs".
The "Fs" type has a trait bound on "NodeFs", which specifies APIs
required for all ops and resolution APIs to function.
A "RealFs" implementation of "NodeFs" is exported from the "deno_node"
crate, that provides a default implementation for the trait.
All code in "deno_node" extension was changed to use the "NodeFs" trait
to handle file system operations, instead of relying on APIs from the
standard library.
Currently the `processenv` feature is not explicitly requested by
`deno_io`, however it is using the `processenv` module. This will
prevent downstream users from building on Windows.
I'd assume that this doesn't popup in Deno itself since another crate is
enabling this feature.
This commit changes the type parameter for "deno_node" extension, from
`P: NodePermission` to `Env: NodeEnv`.
`NodeEnv` is a new trait that has associated type `P: NodePermission`.
This is a stepping stone to support swappable file system for the
extension, that will be added as a second associated type to the
`NodeEnv` trait.
Towards #18455
This commit implements `checkPrimeSync` and `checkPrime` in node:crypto
using the Miller-Rabin primality test (fun fact: it actually is a test
for composite numbers)
It first compares the candidate against many known small primes and if
not, proceeds to run the Miller-Rabin primality test.
http://nickle.org/examples/miller-rabin.5c used as reference
implementation.
This internal node hook is used by libraries such as `ts-node` when used
as a require hook `node -r ts-node/register`. That combination is often
used with test frameworks like `mocha` or `jasmine`.
We had a reference to `Module._preloadModules` in our code, but the
implementation was missing. While fixing this I also noticed that the
`fakeParent` module that we create internally always threw because of
the `pathDirname` check on the module id in the constructor of `Mdoule`.
So this code path was probably broken for a while.
```txt
✖ ERROR: Error: Empty filepath.
at pathDirname (ext:deno_node/01_require.js:245:11)
at new Module (ext:deno_node/01_require.js:446:15)

Since we can preserve ops in the snapshot these days, we no longer
need to have "Deno[Deno.internal].nodeUnstable" namespace.
Instead, various built-in Node.js modules can use appropriate APIs
directly.
This commit adds the `crypto.createSecretKey` API.
Key management: This follows the same approach as our WebCrypto
CryptoKey impl where we use WeakMap for storing key material and a
handle is passed around, such that (only internal) JS can access the key
material and we don't have to explicitly close a Rust resource.
As a result, `createHmac` now accepts a secret KeyObject.
Closes https://github.com/denoland/deno/issues/17844
This will improve diagnostics and catch any non-ASCII extension code
early.
This will use `debug_assert!` rather than `assert!` to avoid runtime
costs, and ensures (in debug_assert mode only) that all extension source
files are ASCII as we load them.
No need for two almost identical implementations of the same thing

Previously the mapping between `AnyValue::Bool` and `KeyPart::Bool` was
inverted.
This patch also allows using the empty key `[]` as range start/end to
`snapshot_read`.
Currently `Deno.openKv(":memory:")` requests read+write permissions for
`./:memory:` even though no file is read or written. Also added some
guards for special sqlite paths that were unintentionally opted into.

Reduce the number of copies and allocations of script code by carrying
around ownership/reference information from creation time.
As an advantage, this allows us to maintain the identity of `&'static
str`-based scripts and use v8's external 1-byte strings (to avoid
incorrectly passing non-ASCII strings, debug `assert!`s gate all string
reference paths).
Benchmark results:
Perf improvements -- ~0.1 - 0.2ms faster, but should reduce garbage
w/external strings and reduces data copies overall. May also unlock some
more interesting optimizations in the future.
This requires adding some generics to functions, but manual
monomorphization has been applied (outer/inner function) to avoid code
bloat.
This PR changes the inspect result of anonymous functions from
`[Function]` to `[Function (anonymous)]`. This behavior is aligned
to `util.inspect` of Node.js.
Moving some code around in `ext/node` is it's a bit better well defined
and makes it possible for others to embed it.
I expect to see no difference in startup perf with this change.
These functions don't need to be async, as they are only calling
synchronous JavaScript code. As a follow up, all 3 functions
should be merge together - this will reduce roundtrips for
calling V8 from Rust, which is somewhat expensive
This commit changes the build process in a way that preserves already
registered ops in the snapshot. This allows us to skip creating hundreds of
"v8::String" on each startup, but sadly there is still some op registration
going on startup (however we're registering 49 ops instead of >200 ops).
This situation could be further improved, by moving some of the ops
from "runtime/" to a separate extension crates.

Follow-up to #18210:
* we are passing the generated `cfg` object into the state function
rather than passing individual config fields
* reduce cloning dramatically by making the state_fn `FnOnce`
* `take` for `ExtensionBuilder` to avoid more unnecessary copies
* renamed `config` to `options`
This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements:
* `deno_core::ops!` registers a block of `#[op]`s, optionally with type
parameters, useful for places where we share lists of ops
* `deno_core::extension!` is used to register an extension, and creates
two methods that can be used at runtime/snapshot generation time:
`init_ops` and `init_ops_and_esm`.

This tweaks the signature of `request_builder_hook` in order to support
fallible hooks.
The rationale for this is mostly on two sides:
* it allows a hook to inspect and possibly drop an outgoing request
(e.g. for policying purposes), bubbling up a detailed error message to
the user.
* it wires into newer `reqwest` API which allows to split and then
reassemble a `RequestBuilder`, although only in a fallible way

This commit removes "deno_core::RuntimeOptions::extensions_with_js".
Now it's embedders' responsibility to properly register extensions
that will not contains JavaScript sources when running from an existing
snapshot.
Prerequisite for https://github.com/denoland/deno/pull/18080
This commit partially reverts changes from
https://github.com/denoland/deno/pull/18095.
Turns out I made a mistake that became apparent when working
on removing "RuntimeOptions::extensions_with_js" in a follow up.
This commit splits "<ext_name>::init" functions into "init_ops" and
"init_ops_and_esm". That way we don't have to construct list of
ESM sources on each startup if we're running with a snapshot.
In a follow up commit "deno_core" will be changed to not have a split
between "extensions" and "extensions_with_js" - it will be embedders'
responsibility to pass appropriately configured extensions.
Prerequisite for https://github.com/denoland/deno/pull/18080
This commit changes how "unload" event is handled - before
this commit an event listener was added unconditionally in
the runtime bootstrapping function, which for some reason was
very expensive (0.3ms). Instead of adding an event listener,
a check was added to "dispatchEvent" function that performs
the same action (so it's only called if there's an event dispatched).
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020
Since we are snapshotting extension source at build time, there's no
need to define list of sources for the extension at runtime.
This commit changes "deno_node" extension by removing "init_polyfill"
function in favor of "init_polyfill_ops_and_esm()" and "init_polyfill_ops()".
The former is used during snapshot and when "deno_runtime" is compiled
with "dont_create_runtime_snapshot" cargo feature flag. The latter is used
when running a worker from an existing snapshot.
This is a start of a bigger refactor to all extensions - thanks to this
change, we don't have to iterate over all defined source files for extension at
runtime, and because of that we don't have to create a filepath for each of the
source files. It's not a big deal, but we are iterating over 300 files on each start,
and concatenating 3 strings before creating a "PathBuf" for ~200 of them.
This is already visible on the startup flamegraphs and should be avoided.
There's no point for this API to expect result. If something fails it should
result in a panic during build time to signal to embedder that setup is
wrong.
This API is required by several extensions like "ext/node", "ext/ffi"
and also FS APIs that we want to move to a separate crate. Because
of that "pathFromURL" API was moved to "deno_web" extension so
other extension crates can rely on it.
This commit changes "InternalModuleLoader" from "deno_core" to
store a list of used modules during snapshotting. If a module was not
used during snapshotting "InternalModuleLoader" will panic in its "Drop"
handler signaling to the embedder that they made a mistake somewhere.
We use information about build in several extension crates like
"ext/node" or "runtime/". In an effort to move "fs" APIs to a separate
crate it is a prerequisite to have this information available outside
of the "runtime/" crate.
This commit moves definition of "build" object to "Deno.core" that is
later forwarded to "Deno.build".
Join two independent ops into one. A fast impl of one + a slow callback
of another. Here's an example showing optimized paths for latin-1 via
fast call and the next-best fallback using V8 apis.
```rust
#[op(v8)]
fn op_encoding_encode_into_fallback(
scope: &mut v8::HandleScope,
input: serde_v8::Value,
// ...
#[op(fast, slow = op_encoding_encode_into_fallback)]
fn op_encoding_encode_into(
input: Cow<'_, str>,
// ...
```
Benchmark results of the fallback path:

JavaScript APIs from "runtime/js/40_files.js" combined abstractions
for stdio streams ("Stdout", "Stderr", "Stdin") and file system file
("File", "FsFile"). APIs from "runtime/js/40_read_file.js" and
"runtime/js/40_write_file.js" were implemented using ops from
"runtime/ops/fs.rs".
This file was removed and relevant APIs were moved to "deno_io/12_io.js"
and "runtime/js/30_fs.js".
This work is meant to enable factoring out "deno_fs" crate.
This commit changes "include_js_files!" macro from "deno_core"
in a way that "dir" option doesn't cause specifiers to be rewritten
to include it.
Example:
```
include_js_files! {
dir "js",
"hello.js",
}
```
The above definition required embedders to use:
`import ... from "internal:<ext_name>/js/hello.js"`.
But with this change, the "js" directory in which the files are stored
is an implementation detail, which for embedders results in:
`import ... from "internal:<ext_name>/hello.js"`.
The directory the files are stored in, is an implementation detail and
in some cases might result in a significant size difference for the
snapshot. As an example, in "deno_node" extension, we store the
source code in "polyfills" directory; which resulted in each specifier
to look like "internal:deno_node/polyfills/<module_name>", but with
this change it's "internal:deno_node/<module_name>".
Given that "deno_node" has over 100 files, many of them having
several import specifiers to the same extension, this change removes
10 characters from each import specifier.
This is a super basic initial implementation. We don't create a
`node_modules/.bin` folder at the moment and add it to the PATH like we
should which is necessary to make command name resolution in the
subprocess work properly (ex. you run a script that launches another
script that then tries to launch an "npx command"... this won't work
atm).
Closes #17492
This changes npm specifiers to be handled by deno_graph and resolved to
an npm package name and version when the specifier is encountered. It
also slightly changes how npm specifier resolution occurs—previously it
would collect all the npm specifiers and resolve them all at once, but
now it resolves them on the fly as they are encountered in the module
graph.

This commits adds auto-discovery of "package.json" file when running
"deno run" and "deno task" subcommands. In case of "deno run" the
"package.json" is being looked up starting from the directory of the
script that is being run, stopping early if "deno.json(c)" file is found
(ie. FS tree won't be traversed "up" from "deno.json").
When "package.json" is discovered the "--node-modules-dir" flag is
implied, leading to creation of local "node_modules/" directory - we
did that, because most tools relying on "package.json" will expect
"node_modules/" directory to be present (eg. Vite). Additionally
"dependencies" and "devDependencies" specified in the "package.json"
are downloaded on startup.
This is a stepping stone to supporting bare specifier imports, but
the actual integration will be done in a follow up commit.

This commit changes definition of "ExtensionFileSource", by changing
"code" field to being "ExtensionFileSourceCode" enum. Currently the enum
has only a single variant "IncludedInBinary". It is done in preparation
to allow embedders to decide if they want to include the source code in the
binary when snapshotting (in most cases they shouldn't do that).
In the follow up commit we'll add more variants to
"ExtensionFileSourceCode".
"include_js_files_dir!" macro was removed in favor "include_js_files!"
macro which can now accept "dir" option.

Fixes denoland#16922.
The error messages in the `ffi` module are somewhat cryptic when passing
functions that have invalid `parameters` or `result` type strings. While
the generated serializer for the `ForeignFunction` struct correctly
outputs a correct and verbose message, the user sees a far less helpful
`data did not match any variant` message instead.
The underlying cause appears to be the fallback message in the
auto-derived deserializer for untagged enums [1] generated as a result
of `ForeignSymbol` being marked as `#[serde(untagged)]` [2]. Passing an
unexpected value for `NativeType` causes it to error out while
attempting to deserialize both enum variants -- once because it's not a
match for the `ForeignStatic` variant, and once because the
`ForeignFunction` deserializer rejects the invalid type for the
parameters/return type. This is currently open as [serde
#773](https://github.com/serde-rs/serde/issues/773), and not a trivial
exercise to fix generically.

[2] https://github.com/denoland/deno/blob/main/ext/ffi/dlfcn.rs#L102
[3] https://github.com/serde-rs/serde/issues/773
Note that the auto-generated deserializer for untagged enums uses a
private API to buffer deserializer content that we don't have access to.
Instead, we can make use of the `serde_value` crate to buffer the
values. This can likely be removed once the official buffering API lands
(see [4] and [5]). In addition, this crate pulls in `serde_json` as a
cheap way to test that the deserializer works properly.

This commit moves "deno_std/node" in "ext/node" crate. The code is
transpiled and snapshotted during the build process.
During the first pass a minimal amount of work was done to create the
snapshot, a lot of code in "ext/node" depends on presence of "Deno"
global. This code will be gradually fixed in the follow up PRs to migrate
it to import relevant APIs from "internal:" modules.
Currently the code from snapshot is not used in any way, and all
Node/npm compatibility still uses code from
"https://deno.land/std/node" (or from the location specified by
"DENO_NODE_COMPAT_URL"). This will also be handled in a follow
up PRs.

This was not caught in the previous test case, as the response body was
smaller than the size of `HEAD` response.
This made `nwritten < responseLen` check in `writeFixedResponse` to
fail, and not trigger `op_flash_respond_async` as a result.
When the response body is larger than the `HEAD` though, as in the
updated test case (`HEAD` i 120 bytes, where our response is 300 bytes),
it would think that we still have something to send, and effectively
panic, as `op_flash_respond` already removed the request from the pool.
This change, makes the `handleResponse` function always calculate the
number of bytes to transmit when `HEAD` request is encountered.
Effectively ignoring `Content-Length` of the body, but still setting it
correctly in the request header itself.

This commit moves some code around from "cli/node/mod.rs" to
"ext/node". Additionally "ext/node" was changed to factor out
"ops.rs" and "polyfill.rs" modules.
This commit does preparatory work to allow snapshotting Node.js
compatibility layer, that currently lives in `std/node`. The logic was
changed to allow loading some modules from the snapshot and
some from the remote URL.
Additionally "module_es_shim.js" that provides exports for "node:module"
is now snapshotted.
