This commit removes some of the technical debt related
to snapshotting JS code:
- "cli/ops/mod.rs" and "cli/build.rs" no longer define "cli" extension
which was not required anymore
- Cargo features for "deno_runtime" crate have been unified in
"cli/Cargo.toml"
- "cli/build.rs" uses "deno_runtime::snapshot::create_runtime_snapshot"
API
instead of copy-pasting the code
- "cli/js/99_main.js" was completely removed as it's not necessary
anymore
Towards https://github.com/denoland/deno/issues/21137
Fixes #21121 and #19498
Migrates fully to rustls_tokio_stream. We no longer need to maintain our
own TlsStream implementation to properly support duplex.
This should fix a number of errors with TLS and websockets, HTTP and
"other" places where it's failing.
We only want one zlib dependency.
Zlib dependencies are reorganized so they use a hidden
`__vendored_zlib_ng` flag in cli that enables zlib-ng for both libz-sys
(used by ext/node) and flate2 (used by deno_web).
This is the release commit being forwarded back to main for 1.38.1

We can move all promise ID knowledge to deno_core, allowing us to better
experiment with promise implementation in deno_core.
`{un,}refOpPromise(promise)` is equivalent to
`{un,}refOp(promise[promiseIdSymbol])`
This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"
These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).
These flags can also be specified in `deno.json` file under `unstable`
key.
Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.
This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.
* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.
This commit updates the ext/kv module to use the denokv_* crates for
the protocol and the sqlite backend. This also fixes a couple of bugs in
the sqlite backend, and updates versionstamps to be updated less
linearly.
Rewrites 3 ops that used "op(deferred)" to use "op2(async(lazy))"
instead.
This will allow us to remove codepath for handling "deferred" ops in
"deno_core".
Closes #14122.
Adds two extensions to `--allow-run` behaviour:
- When `--allow-run=foo` is specified and `foo` is found in the `PATH`
at startup, `RunDescriptor::Path(which("foo"))` is added to the
allowlist alongside `RunDescriptor::Name("foo")`. Currently only the
latter is.
- When run permission for `foo` is queried and `foo` is found in the
`PATH` at runtime, either `RunDescriptor::Path(which("foo"))` or
`RunDescriptor::Name("foo")` would qualify in the allowlist. Currently
only the latter does.
Adds `runtime/shared.rs` which is imported by both `build.rs` and the
rest of the crate, containing utilities used by both.
Renames the `snapshot_from_snapshot` feature to
`exclude_runtime_main_js` since that's what it does and it's relevant
outside of snapshotting when `__runtime_js_sources` is specified.

This patch adds a `remote` backend for `ext/kv`. This supports
connection to Deno Deploy and potentially other services compatible with
the KV Connect protocol.
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:
- [x] Process stdin/stdout/stderr are lazily created
- [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

Closes #19399 (running without snapshots at all was suggested as an
alternative solution).
Adds a `__runtime_js_sources` pseudo-private feature to load extension
JS sources at runtime for faster development, instead of building and
loading snapshots or embedding sources in the binary. Will only work in
a development environment obviously.
Try running `cargo test --features __runtime_js_sources
integration::node_unit_tests::os_test`. Then break some behaviour in
`ext/node/polyfills/os.ts` e.g. make `function cpus() {}` return an
empty array, and run it again. Fix and then run again. No more build
time in between.
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This addresses issue #19918.
## Issue description
Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.
This is my first ever contribution to Deno, so I might be missing
something.
Code run within Deno-mode and Node-mode should have access to a
slightly different set of globals. Previously this was done through a
compile time code-transform for Node-mode, but this is not ideal and has
many edge cases, for example Node's globalThis having a different
identity than Deno's globalThis.
This commit makes the `globalThis` of the entire runtime a semi-proxy.
This proxy returns a different set of globals depending on the caller's
mode. This is not a full proxy, because it is shadowed by "real"
properties on globalThis. This is done to avoid the overhead of a full
proxy for all globalThis operations.
The globals between Deno-mode and Node-mode are now properly segregated.
This means that code running in Deno-mode will not have access to Node's
globals, and vice versa. Deleting a managed global in Deno-mode will
NOT delete the corresponding global in Node-mode, and vice versa.
