fs(read(fd[, options], callback)): throw `ERR_INVALID_ARG_TYPE` when `options.buffer` is `null` #44769

wafuwafu13 · 2022-09-24T12:56:46Z

when params is { buffer: null }, buffer is not initialized with Buffer.alloc(16384). so error message became not user-friendly as seen in test case.

node/lib/fs.js

Line 621 in abfeed8

({ buffer = Buffer.alloc(16384) } = params ?? kEmptyObject);

test/parallel/test-fs-read.js

+  {
+    name: 'TypeError',
+    message: 'The "buffer" argument must be an instance of Buffer, ' +
+    'TypedArray, or DataView. Received null',
+  },


Let's not validate the message, but rather the error code.

Suggested change

{

name: 'TypeError',

message: 'The "buffer" argument must be an instance of Buffer, ' +

'TypedArray, or DataView. Received null',

},

{ code: 'ERR_INVALID_ARG_TYPE' },

👍 fixed b7ba2c3

LiviaMedeiros

Good catch!

It introduces double validation for fs.read(fd, params, callback) case:

node/lib/fs.js

Line 641 in b7ba2c3

validateBuffer(buffer);

We can either replace the old validation with checks in all applicable branches, or ignore the original error and rely on unconditional validation later, for example:

      offset = 0,
-     length = buffer.byteLength - offset,
+     length = buffer?.byteLength - offset,
      position = null,

WDYT?

It looks good to me so fixed! 888beff

This needs al least another approval from someone on @nodejs/tsc to land.
