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.
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).

Adds a `deno.preloadLimit` option (ex. `"deno.preloadLimit": 2000`)
which specifies how many file entries to traverse on the file system
when the lsp loads or its configuration changes.
Closes #18955
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).
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.
Fixes #18979.
This changes the predicate for allowing `ext:` specifier resolution from
`snapshot_loaded_and_not_snapshotting` to `ext_resolution_allowed` which
is only set to true during the extension module loading phase. Module
loaders as used in core
are now declared as `ExtModuleLoader` rather than `dyn ModuleLoader`.
`new Deno.KvU64(1n) + 2n == 3n` is now true.
`new Deno.KvU64(1n)` is now inspected as `[Deno.KvU64: 1n]`
(`Object(1n)` is inspected as `[BigInt: 1n]`).

This commit changes how paths for npm packages are handled,
by canonicalizing them when resolving. This is done so that instead
of returning
"node_modules/<package_name>@<version>/node_modules/<dep>/index.js"
(which is a symlink) we "node_modules/<dep>@<dep_version>/index.js.

This removes `ProcState` and replaces it with a new `CliFactory` which
initializes our "service structs" on demand. This isn't a performance
improvement at the moment for `deno run`, but might unlock performance
improvements in the future.
- Do not use `ReflectHas` in `isNode`.
- Avoid copying handler array when handlers.length == 1
- Avoid searching for path target when path.length == 1

`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.
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.
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.
1. Adds cli/standalone folder
2. Writes the bytes directly to the output file. When adding npm
packages this might get quite large, so let's not keep the final output
in memory just in case.

This commit implements the keypair generation for asymmetric keys for
the `generateKeyPair` API.
See how key material is managed in this implementation:
https://www.notion.so/denolandinc/node-crypto-design-99fc33f568d24e47a5e4b36002c5325d?pvs=4
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.
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.
This commit refactors "deno_core" to do fewer boundary crossings
from Rust to V8. In other words we are now calling V8 from Rust fewer
times.
This is done by merging 3 distinct callbacks into a single one. Instead
of having "op resolve" callback, "next tick" callback and "macrotask
queue" callback, we now have only "Deno.core.eventLoopTick" callback,
which is responsible for doing the same actions previous 3 callbacks.
On each of the event loop we were doing at least 2 boundary crosses
(timers macrotask queue callback and unhandled promise rejection
callback) and up to 4 crosses if there were op response and next tick
callbacks coming from Node.js compatibility layer. Now this is all done
in a single callback.
Closes https://github.com/denoland/deno/issues/18620
Stores the test/bench functions in rust op state during registration.
The functions are wrapped in JS first so that they return a directly
convertible `TestResult`/`BenchResult`. Test steps are still mostly
handled in JS since they are pretty much invoked by the user. Allows
removing a bunch of infrastructure for communicating between JS and
rust. Allows using rust utilities for things like shuffling tests
(`Vec::shuffle`). We can progressively move op and resource sanitization
to rust as well.
Fixes #17122.
Fixes #17312.
Fixes #6259.
Adds the location for v8 syntax errors to the message (`message += " at
{location}"`) when rethrowing them for dynamic imports.
Discussing with @bartlomieju on discord I proposed just preserving v8's
error and not reconstructing it, allowing the standard stack trace to
just point to the syntax error instead of the dynamic import. But on
further thought this way has parity with SWC's syntax errors + has the
advantage of showing both the syntax error and dynamic import location.
```ts
// temp.js
await import("./temp2.js");
// temp2.js
function foo() {
await Promise.resolve();
}
// Before:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1
// After:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word at file:///.../temp2.js:2:3
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1

This reloads an npm package's dependency's information when a
version/version req/tag is not found.
This PR applies only to dependencies of npm packages. It does NOT yet
cause npm specifiers to have their dependency information cache busted.
That requires a different solution, but this should help cache bust in
more scenarios.

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.
1. Fixes a cosmetic issue in the repl where it would display lsp warning
messages.
2. Lazily loads dependencies from the package.json on use.
3. Supports using bare specifiers from package.json in the REPL.
Closes #17929

We currently run the all test cases in `parallel` category at the same
time, which invokes hundreds process at the same time, and that seems
causing some flakiness in CI. (maybe related to #18487)
This PR limits the concurrency to the number of cpu cores. This is more
aligned to how Node.js run their `parallel` test in their repository.
42c4a35952/Makefile (L356)
1. Rewrites the tests to be more back and forth rather than getting the
output all at once (which I believe was causing the hangs on linux and
maybe mac)
2. Runs the pty tests on the linux ci.
3. Fixes a bunch of tests that were just wrong.
4. Adds timeouts on the pty tests.

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 gets SQLite off the flamegraph and reduces initialization time by
somewhere between 0.2ms and 0.5ms. In addition, I took the opportunity
to move all the cache management code to a single place and reduce
duplication. While the PR has a net gain of lines, much of that is just
being a bit more deliberate with how we're recovering from errors.
The existing caches had various policies for dealing with cache
corruption, so I've unified them and tried to isolate the decisions we
make for recovery in a single place (see `open_connection` in
`CacheDB`). The policy I chose was:
1. Retry twice to open on-disk caches
2. If that fails, try to delete the file and recreate it on-disk
3. If we fail to delete the file or re-create a new cache, use a
fallback strategy that can be chosen per-cache: InMemory (temporary
cache for the process run), BlackHole (ignore writes, return empty
reads), or Error (fail on every operation).
The caches all use the same general code now, and share the cache
failure recovery policy.
In addition, it cleans up a TODO in the `NodeAnalysisCache`.
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)
at Function.Module._resolveFilename (ext:deno_node/01_require.js:754:28)
at Function.resolve (ext:deno_node/01_require.js:1015:19)
```
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.

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.
This commit adds unstable "Deno.openKv()" API that allows to open
a key-value database at a specified path.

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.
This commit adds support for spawning Web Workers in self-contained
binaries created with "deno compile" subcommand.
As long as module requested in "new Worker" constructor is part of the
eszip (by means of statically importing it beforehand, or using "--include"
flag), then the worker can be spawned.
This change will enable dynamic imports and web workers to use modules
not reachable from the main module, by passing a list of extra side
module roots as options to `deno compile`.
This can be done by specifying "--include" flag that accepts a file path or a
URL. This flag can be specified multiple times, to include several modules.
The modules specified with "--include" flag, will be added to the produced
"eszip".
This PR _**temporarily**_ removes WebGPU (which has behind the
`--unstable` flag in Deno), due to performance complications due to its
presence.
It will be brought back in the future; as a point of reference, Chrome
will ship WebGPU to stable on 26/04/2023.

This commit changes "deno_core" to not rely on implicitly calling
"std::env::current_dir()" when resolving module specifiers using
APIs from "deno_core::modules_specifier".
Supersedes https://github.com/denoland/deno/pull/15454
This commit changes current "deno_core::resolve_url_or_path" API to
"resolve_url_or_path_deprecated" and adds new "resolve_url_or_path"
API that requires to explicitly pass the directory from which paths
should be resolved to.
Some of the call sites were updated to use the new API, the reminder
of them will be updated in a follow up PR.
Towards landing https://github.com/denoland/deno/pull/15454
Creating the node_modules folder when the packages are already
downloaded can take a bit of time and not knowing what is going on can
be confusing. It's better to show a progress bar.
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
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".
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.
denoland/eszip#115 added support for statically-analyzed dynamic imports
in eszip, which made `deno compile` support dynamic imports starting
from #17858. This PR adds a test for it.

This test is adapted from PR #17663.

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 commit enables resolution of "bare specifiers" (eg. "import express
from 'express';") if a "package.json" file is discovered.

without any changes.

any changes to the user code.

This commit adds new "A" option to the interactive permission prompt, that will
allow all subsequent permissions for given group (domain). Ie. when querying for
permissions to access eg. env variables responding with "A" will allow access
to all environmental variables.
This works for all permission domains and should make permission prompts
more ergonomic for users.
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.
