2024-01-18feat: Start warning on each use of a deprecated API (#21939)Bartek Iwańczuk
This commit introduces deprecation warnings for "Deno.*" APIs. This is gonna be quite noisy, but should tremendously help with user code updates to ensure smooth migration to Deno 2.0. The warning is printed at each unique call site to help quickly identify where code needs to be adjusted. There's some stack frame filtering going on to remove frames that are not useful to the user and would only cause confusion. The warning can be silenced using "--quiet" flag or "DENO_NO_DEPRECATION_WARNINGS" env var. "Deno.run()" API is now using this warning. Other deprecated APIs will start warning in follow up PRs. Example: ```js import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts"; const p = Deno.run({ cmd: [ Deno.execPath(), "eval", "console.log('hello world')", ], }); await p.status(); p.close(); async function runEcho() { const p = Deno.run({ cmd: [ Deno.execPath(), "eval", "console.log('hello world')", ], }); await p.status(); p.close(); } await runEcho(); await runEcho(); for (let i = 0; i < 10; i++) { await runEcho(); } await runEcho2(); ``` ``` $ deno run --allow-read foo.js Warning ├ Use of deprecated "Deno.run()" API. │ ├ This API will be removed in Deno 2.0. Make sure to upgrade to a stable API before then. │ ├ Suggestion: Use "Deno.Command()" API instead. │ └ Stack trace: └─ at file:///Users/ib/dev/deno/foo.js:3:16 hello world Warning ├ Use of deprecated "Deno.run()" API. │ ├ This API will be removed in Deno 2.0.

This commit adds support for "rejectionhandled" Web Event and "rejectionHandled" Node event. ```js import process from "node:process"; process.on("rejectionHandled", (promise) => { console.log("rejectionHandled", reason, promise); }); window.addEventListener("rejectionhandled", (event) => { console.log("rejectionhandled", event.reason, event.promise); }); ``` --------- Co-authored-by: Matt Mastracci <matthew@mastracci.com>

2024-01-04fix: strict type check for cross realms (#21669)Kenta Moriuchi
Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when using `Object.prototype.isPrototypeOf` to check built-in types. ```js import vm from "node:vm"; const err = new Error(); const crossErr = vm.runInNewContext(`new Error()`); console.assert( !(crossErr instanceof Error) ); console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) ); ``` This PR changes to check using internal slots solves them. --- current: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error {} > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) Date {} ``` this PR: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error: message at <anonymous>:1:1 > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) 2018-12-10T02:26:59.002Z ``` --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>

2023-12-27perf: remove opAsync (#21690)Matt Mastracci
`opAsync` requires a lookup by name on each async call. This is a mechanical translation of all opAsync calls to ensureFastOps. The `opAsync` API on Deno.core will be removed at a later time.
2023-12-15refactor: setup child process pipe in Rust (#21579)Divy Srivastava
Avoid passing the fd into JS and back into Rust. Instead we setup the child's end of the pipe directly using a special Rust op.
2023-12-13fix: implement child_process IPC (#21490)Divy Srivastava
This PR implements the Node child_process IPC functionality in Deno on Unix systems. For `fd > 2` a duplex unix pipe is set up between the parent and child processes. Currently implements data passing via the channel in the JSON serialization format.
2023-12-08fix(unstable): Honor granular unstable flags in js runtime (#21466)Julien Cayzac
This fixes #21434 for `BroadcastChannel` and `WebSocketStream`. `--unstable` still enable both, but granular unstable flags now also work: * `--unstable-net` now enables `WebSocketStream`. * `--unstable-broadcast-channel` now enables `BroadcastChannel`. * Additionally, there are now tests for all granular unstable flags. Since `unsafe-proto` already had tests, so I didn't add any for this one. It also introduces a map to keep track of granular unstable ids without having to sync multiple places.
2023-12-07refactor: pull 'core', 'internals', 'primordials' from ES module (#21462)Bartek Iwańczuk
This commit refactors how we access "core", "internals" and "primordials" objects coming from `deno_core`, in our internal JavaScript code. Instead of capturing them from "globalThis.__bootstrap" namespace, we import them from recently added "ext:core/mod.js" file.
2023-12-06chore: bump deno_core and update tests (#21467)Matt Mastracci
Landing changes required for https://github.com/denoland/deno_core/pull/359 We needed to update 99_main.js and a whole load of tests. API changes: - setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler. The function is now called from eventLoopTick. - The promiseRejectMacrotaskCallback no longer exists, as this is automatically handled in eventLoopTick. - ops.op_dispatch_exception now takes a second parameter: in_promise. The preferred way to call this op is now reportUnhandledException or reportUnhandledPromiseRejection.

2023-11-01feat: granular --unstable-* flags (#20968)Bartek Iwańczuk
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.

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 Benchmarking this PR (`89de7e1ff`) vs main (`41cad2179`) ``` 12:36 $ third_party/prebuilt/mac/hyperfine --warmup 100 -S none './deno-41cad2179 run ./empty.js' './deno-89de7e1ff run ./empty.js' Benchmark 1: ./deno-41cad2179 run ./empty.js Time (mean ± σ): 24.3 ms ± 1.6 ms [User: 16.2 ms, System: 6.0 ms] Range (min … max): 21.1 ms … 29.1 ms 115 runs Benchmark 2: ./deno-89de7e1ff run ./empty.js Time (mean ± σ): 24.0 ms ± 1.4 ms [User: 16.3 ms, System: 5.6 ms] Range (min … max): 21.3 ms … 28.6 ms 126 runs ``` Fixes https://github.com/denoland/deno/issues/20142 Fixes https://github.com/denoland/deno/issues/15826 Fixes https://github.com/denoland/deno/issues/20028

2023-07-31fix: call setIsTrusted for generated events (MessageEvent) (#19919)Ricardo Iván Vieitez Parra
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.
2023-07-19feat(ext/node): properly segregate node globals (#19307)Luca Casonato
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. --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com> Co-authored-by: Aapo Alasuutari <aapo.alasuutari@gmail.com>

2023-06-14perf: don't run microtask checkpoint if macrotask callback did no work (#19492)Bartek Iwańczuk

2023-05-24fix(node): fire 'unhandledrejection' event when using node: or npm: imports ↵Bartek Iwańczuk
(#19235) 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.

2023-03-28refactor(runtime): manual serialization of bootstrap data (#18448)Bartek Iwańczuk
This commit changes how data required to bootstrap main and worker runtime is serialized. Instead of relying on serde_v8 and using JSON object, we're doing manual serialization to a "v8::Array". This limits number of V8 strings that need to be serialized by 16. It also made it clear that some data could be obtained during snapshotting instead of during bootstrap.

(#18458) …#18449)" This reverts commit d1a9c4cd7ce0c19ddf9c7c52c0d35d6124a7677d. Appears this made CI very flaky on macOS, but I can't repeat it locally yet
2023-03-27refactor: remove Deno[Deno.internal].nodeUnstable namespace (#18449)Bartek Iwańczuk
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.
2023-03-09perf: don't add unload event listener (#18082)Bartek Iwańczuk
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).
2023-03-08refactor: rename InternalModuleLoader to ExtModuleLoader, use ext: scheme ↵Bartek Iwańczuk
for snapshotted modules (#18041) 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

2023-03-05refactor: move definition of Deno.build from "runtime" to "core" (#18036)Bartek Iwańczuk
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".
