[BUG] BrokenPipe Crash

See original GitHub issue



deno 1.6.3 (release, x86_64-unknown-linux-gnu) v8 8.8.294 typescript 4.1.3

  • Opine Version: 1.0.0

Uncaught BrokenPipe: Broken pipe (os error 32)


Hello, it’s been a while since Opine crashed randomly with a system error, at the time it was on my mac, now on my windows and also on a linux server, the error returned is still the same:

error: Uncaught (in promise) BrokenPipe: Broken pipe (os error 32)
    at unwrapResponse (deno:runtime/js/10_dispatch_minimal.js:59:13)
    at sendAsync (deno:runtime/js/10_dispatch_minimal.js:98:12)
    at async write (deno:runtime/js/12_io.js:117:20)
    at async BufWriter.write (bufio.ts:499:29)
    at async writeResponse (_io.ts:273:15)
    at async Proxy.respond (server.ts:84:7)
    at async Response.end (response.ts:256:7)

Maybe you have to surround Opine with a try catch? The crash occurs with any code that uses opine, however I noticed that the more routes there are, the more often it happens

Ah nice @Tc-001 that will be useful for repro + figuring out if fix. Can probably add a “racing server” like integration test similar to what the std/http module has for these kind of edge cases in real world apps.

Thanks for the fast reply!

For future reference, I could reproduce it by

app.get("/",  function(req, res) {
  res.send("a ".repeat(9999999));

and spamming F5 in firefox. This cancels the previous load before re-requesting the page. There is probably a better way, but this worked in a pinch.
