2024-08-15feat(lint): Add lint for usage of node globals (with autofix) (#25048)Nathan Whitaker
From upgrading `deno_lint`. Previously if you had a node project that used a bunch of node globals (`process.env`, etc), you would have to fix the errors by hand. This PR includes a new lint that detects usages of node globals (`process`, `setImmediate`, `Buffer`, etc.) and provides an autofix to import the correct value. For instance: ```ts // main.ts const _foo = process.env.FOO; ``` `deno lint` gives you ```ts error[no-node-globals]: NodeJS globals are not available in Deno --> /home/foo.ts:1:14 | 1 | const _foo = process.env.FOO; | ^^^^^^^ = hint: Add `import process from "node:process";` docs: https://lint.deno.land/rules/no-node-globals Found 1 problem (1 fixable via --fix) Checked 1 file ``` And `deno lint --fix` adds the import for you: ```ts // main.ts import process from "node:process"; const _foo = process.env.FOO; ```
2024-08-15refactor: remove version::is_canary(), use ReleaseChannel instead (#25053)Bartek Iwańczuk
In preparation for https://github.com/denoland/deno/pull/25014, this commit removes public `is_canary()` method and instead uses an enum `ReleaseChannel` to be able to designate more "kinds" of builds.
2024-08-15feat: `deno compile --icon <ico>` (#25039)Divy Srivastava
Add `--icon` flag to set deno compile'd executable icon on Windows. ``` deno compile --icon icon.ico game.tsx ``` Depends on https://github.com/denoland/sui/pull/24 <img width="447" alt="image" src="https://github.com/user-attachments/assets/7f6f3aa0-6872-4975-ae9d-06701b7684b8"> Closes https://github.com/denoland/deno/issues/8912
2024-08-14feat(serve): Opt-in parallelism for `deno serve` (#24920)Nathan Whitaker
Adds a `parallel` flag to `deno serve`. When present, we spawn multiple workers to parallelize serving requests. ```bash deno serve --parallel main.ts ``` Currently on linux we use `SO_REUSEPORT` and rely on the fact that the kernel will distribute connections in a round-robin manner. On mac and windows, we sort of emulate this by cloning the underlying file descriptor and passing a handle to each worker. The connections will not be guaranteed to be fairly distributed (and in practice almost certainly won't be), but the distribution is still spread enough to provide a significant performance increase. --- (Run on an Macbook Pro with an M3 Max, serving `deno.com` baseline:: ``` ❯ wrk -d 30s -c 125 --latency http://127.0.0.1:8000 Running 30s test @ http://127.0.0.1:8000 2 threads and 125 connections Thread Stats Avg Stdev Max +/- Stdev Latency 239.78ms 13.56ms 330.54ms 79.12% Req/Sec 258.58 35.56 360.00 70.64% Latency Distribution 50% 236.72ms 75% 248.46ms 90% 256.84ms 99% 268.23ms 15458 requests in 30.02s, 2.47GB read Requests/sec: 514.89 Transfer/sec: 84.33MB ``` this PR (`with --parallel` flag) ``` ❯ wrk -d 30s -c 125 --latency http://127.0.0.1:8000 Running 30s test @ http://127.0.0.1:8000 2 threads and 125 connections Thread Stats Avg Stdev Max +/- Stdev Latency 117.40ms 142.84ms 590.45ms 79.07% Req/Sec 1.33k 175.19 1.77k 69.00% Latency Distribution 50% 22.34ms 75% 223.67ms 90% 357.32ms 99% 460.50ms 79636 requests in 30.07s, 12.74GB read Requests/sec: 2647.96 Transfer/sec: 433.71MB ```

Which in turn causes an error to be raised which later just short-circuits logic for checking the version and storing it in file. Since fetching from a remote host is always fallible I elected to just return an empty vec of "rc" versions instead of erroring. This might lead to a slight mismatch in some situation when the request actually failed and user is prompted that there's a new canary version, but that is better than not displaying prompt at all. This issue will be fixed more robustly once we move to using SUI for specifying version of the binary.

2024-08-12feat: Rename --unstable-hmr to --watch-hmr (#24975)Bartek Iwańczuk
This commit stabilizes HMR functionality and renames `--unstable-hmr` to `--watch-hmr`. The `--unstable-hmr` flag is still working, but hidden from the help output. It will be removed in Deno 2. Once https://github.com/denoland/deno/pull/24958 lands we should improve grouping of `--watch` and `--watch-hmr` flags.

2024-08-02feat(unstable/fmt): move yaml formatting behind unstable flag (#24848)David Sherret
This moves YAML formatting behind an unstable flag for Deno 1.46. This will make it opt-in to start and then we can remove the flag to make it on by default in version of Deno after that. This can be specified by doing `deno fmt --unstable-yaml` or by specifying the following in a deno.json file: ```json { "unstable": ["fmt-yaml"] } ```

This reland contains a fix that sends "Accept: */*" header for calls made from "FileFetcher". Absence of this header made downloading source code from JSR broken.
