Closes https://github.com/denoland/deno/issues/15277
This commit adds a single "warmup" run of empty function when running
`deno bench`.
This change will break so-called "JIT bias" which makes V8 optimize the
first function
and then bail out of optimization on second function. In essence the
"warmup" function
is getting optimized and then all user benches are bailed out of
optimization.
This PR breaks the addition of the `TestReporter` trait and refactoring
of `PrettyTestReporter` out of #19747. The goal is to enable the
addition of test reporters, including machine readable output.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.
… (#19463)"
This reverts commit ceb03cfb03.
This is being reverted because it causes 3.5Mb increase in the binary
size,
due to runtime JS code being included in the binary, even though it's
already snapshotted.

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()`.
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

When someone explicitly opts into using the node_modules dir via
`--node-modules-dir` or setting `"nodeModulesDir": true` in the
deno.json file, we should eagerly ensure a top level package.json
install is done on startup. This was initially always done when we added
package.json support and a package.json was auto-discovered, but scaled
it back to be lazily done when a bare specifier matched an entry in the
package.json because of how disruptive it was for people using Deno
scripts in Node projects. That said, it does not make sense for someone
to opt-into having deno control and use their node_modules directory and
not want a package.json install to occur. If such a rare scenario
exists, the `DENO_NO_PACKAGE_JSON=1` environment variable can be set.
Ideally, we would only ever use a node_modules directory with this
explicit opt-in so everything is very clear, but we still have this
automatic scenario when there's a package.json in order to make more
node projects work out of the box.
We never properly added support for this. This fixes vendoring when it
has npm or node specifiers. Vendoring occurs by adding a
`"nodeModulesDir": true` property to deno.json then it uses a local
node_modules directory. This can be opted out by setting
`"nodeModulesDir": false` or running with `--node-modules-dir=false`.
Closes #18090
Closes #17210
Closes #17619
Closes #16778
Note: If the package information has already been cached, then this
requires running with `--reload` or for the registry information to be
fetched some other way (ex. the cache busting).

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 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
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.
Fixes regression from #18878 where `Promise.reject()`,
`Promise.reject(undefined)` and `reportError(undefined)` panic in the
REPL.
Fixes `throw undefined` printing `Uncaught Unknown exception` instead of
`Uncaught undefined`.
Fixes #8858.
Fixes #8869.

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.
