npm only makes bin entries executable if they get linked into `.bin`, as
we did before this PR. So this PR actually deviates from npm, because
it's the only reasonable way to fix this that I can think of.
---
The reason this was broken in moment is the following:
Moment has dependencies on two typescript versions: 1.8 and 3.1
If you have two packages with conflicting bin entries (i.e. two
typescript versions which both have a bin entry `tsc`), in npm it is
non-deterministic and undefined which one will end up in `.bin`.
npm, due to implementation differences, chooses to put typescript 1.8
into the `.bin` directory, and so `node_modules/typescript/bin/tsc` ends
up getting marked executable. We, however, choose typescript 3.2, and so
we end up making `node_modules/typescript3/bin/tsc` executable.
As part of its tests, moment executes `node_modules/typescript/bin/tsc`.
Because we didn't make it executable, this fails.
Since the conflict resolution is undefined in npm, instead of trying to
match it, I think it makes more sense to just make bin entries
executable even if they aren't chosen in the case of a conflict.
Fixes #25813.
I initially tried doing this in `deno_semver`, where it's a cleaner
change, but that caused breakage in deno in places where we don't expect
a tag (see https://github.com/denoland/deno/issues/25857).
This does not fix wildcard requirements failing to choose pre-release
versions. That's a little more involved and I'll do a separate PR.
Partially addresses https://github.com/denoland/deno/issues/25648.
This allows packages that use `crossws` to be installed with `deno
install`. `crossws` specifies an optional peer dependency on
`uWebSockets`, but `uWebSockets` is not on npm (it is used with `git:`
or `github:` specifiers). Previously we would error on this, now we
don't error on non-existent optional peer dependencies.
implement require(esm) using `op_import_sync` from deno_core.
possible future changes:
- cts and mts
- replace Deno.core.evalContext to optimize esm syntax detection

Turns out we only virtualized it so one could have a `Console` property,
and the other one not. We can just make this `console.Console` available
everywhere.
PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)
Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).
This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
closes #25008
This change improves the Node.js compatibility in managed npm resolution
mode by disabling the discovery of `node_modules` when the
main specifier is inside of `DENO_DIR`.

Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry

TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes

Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
Previously various reads of files in `node_modules` would error on
invalid UTF-8. These were cases involving:
- reading package.json from Rust
- reading package.json from JS
- reading CommonJS files from JS
- reading CommonJS files from Rust (for ESM translation)
- reading ESM files from Rust
Fixes #24012.
In the case of multiple packages providing a binary with a same name, we
were basically leaving the results undefined (since we set up things in
parallel, and whichever got set up first won). In addition, we were
warning about these cases, even though it's a situation that's expected
to occur.
Instead, in the case of a collision in the binary names, we prefer the
binary provided by the package with the least depth in the dependency
tree.
While I was at it, I also took moved more code to `bin_entries.rs` since
it was starting to get a bit cluttered.
