2023-08-22fix(ext/node): simultaneous reads can leak into each other (#20223)Matt Mastracci
Reported in #20188 This was caused by re-use of a global buffer `BUF` during simultaneous async reads.

Closes https://github.com/denoland/deno/issues/20186
2023-08-16fix(ext/node): allow for the reassignment of userInfo() on Windows (#20165)Evan
The goal of this PR is to address issue #20106 where a `TypeError` occurs when the variables `uid` and `gid` from `userInfo()` in `node:os` are reassigned if the user is on Windows. Both `uid` and `gid` are marked as `const` therefore producing a `TypeError` when the two are reassigned. This PR achieves that goal by marking `uid` and `gid` as `let`
2023-08-16feat(ext/node): eagerly bootstrap node (#20153)Matt Mastracci
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
2023-08-15perf(ext/node): optimize http headers (#20163)Marcos Casagrande
This PR optimizes Node's `IncomingMessageForServer.headers` by replacing `Object.fromEntries()` with a loop and `headers.entries` with `headersEntries` which returns the internal array directly instead of an iterator ## Benchmarks Using `wrk` with 5 headers ``` wrk -d 10s --latency -H "X-Deno: true" -H "Accept: application/json" -H "X-Foo: bar" -H "User-Agent: wrk" -H "Accept-Encoding: gzip, br" http://127.0.0.1:3000 ``` **this PR** ``` Running 10s test @ http://127.0.0.1:3000 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 167.53us 136.89us 2.75ms 97.33% Req/Sec 31.98k 1.38k 36.39k 70.30% Latency Distribution 50% 134.00us 75% 191.00us 90% 234.00us 99% 544.00us 642548 requests in 10.10s, 45.96MB read Requests/sec: 63620.36 Transfer/sec: 4.55MB ``` **main** ``` Running 10s test @ http://127.0.0.1:3000 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 181.31us 132.54us 3.79ms 97.13% Req/Sec 29.21k 1.45k 32.93k 79.21% Latency Distribution 50% 148.00us 75% 198.00us 90% 261.00us 99% 545.00us 586939 requests in 10.10s, 41.98MB read Requests/sec: 58114.01 Transfer/sec: 4.16MB ``` ```js import express from "npm:express"; const app = express(); app.get("/", function (req, res) { req.headers; res.end(); }); app.listen(3000); ```

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>

This makes the implementation of "AsyncLocalStorage" from "node:async_hooks" 3.5x faster than before for noop benchmark (measuring baseline overhead). It's still 3.5x slower than not using `AsyncLocalStorage` and 1.64x slower than using noop promise hooks.
