tls: convertProtocols() error handling #23606

pugbyte · 2018-10-12T18:46:54Z

The convertProtocols() function now throws a range error when the byte
length of a protocol is too long to fit in a Buffer.

Also added a test case in test/parallel/test-tls-basic-validations.js
to cover this.

Changed the byte length error message for protocol to correctly state that the length must be <= 255 not < 255 Amended the test case in test/parallel/test-tls-basic-validations.js

Thanks!

We may or may not consider this semver-major; on the one hand, this adds a new error, on the other hand, output before this patch would have been completely broken and would have failed at another point.

hmm... I think we need to mark as semver-major but let's see if there's @nodejs/tsc consensus on downgrading it.

LGTM

I don't think that this has to be semver major since it was broken before otherwise.

Also changed corresponding usage in lib/tls.js Amended the test case in test/parallel/test-tls-basic-validations.js

I think this should land as patch rather than major. I think the reason is as stated by @BridgeAR above, but I'm willing to supply more detail to the argument if there's disagreement about this.

lib/tls.js

@@ -60,6 +63,10 @@ function convertProtocols(protocols) {
  const lens = new Array(protocols.length);
  const buff = Buffer.allocUnsafe(protocols.reduce((p, c, i) => {
    var len = Buffer.byteLength(c);
+    if (len > 255) {
+      throw new ERR_OUT_OF_RANGE('', '<= 255', len, 'The byte length of the ' +
+        `protocol at index ${i} exceeds the maximum length.`);


When looking at this signature it looks like a mistake that the first argument is an empty string.

I suggest to use the following instead:

ERR_OUT_OF_RANGE(str, range, input, replaceDefaultBoolean)

Using booleans as arguments is not great either but that way the first argument is at least used properly and the reader will hopefully be less surprised (as I would be). We might also use a different more expressive value than a boolean but that could be more error prone.

I've refactored as per your suggestion. Check it out.

I removed the semver-major label due to the comments above. // cc @nodejs/tsc

Thank you for the opportunity. This has been really eye-opening and I'll be much less shy about contributing to open-source projects in the future.

MylesBorins · 2018-11-26T20:30:42Z

it seems like there was some debate regarding if this was Semver-Major or not. As such i'm unsure if it should be backported to LTS

thoughts?
