src: use UV_EINVAL instead of EINVAL in udp_wrap #15444

danbev · 2017-09-17T10:21:05Z

Currently if the buffer size exceeds the maximum int size the following
error will be thrown:

dgram.js:180
    throw new errors.Error('ERR_SOCKET_BUFFER_SIZE', e);
    ^

Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer size: Error:
Unknown system error 22: Unknown system error 22, uv_recv_buffer_size
    at bufferSize (dgram.js:180:11)

It looks like perhaps UV_EINVAL was intended to give the following error
message instead:

dgram.js:180
    throw new errors.Error('ERR_SOCKET_BUFFER_SIZE', e);
    ^

Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer size: Error:
EINVAL: invalid argument, uv_recv_buffer_size
    at bufferSize (dgram.js:180:11)

This commit changes EINVAL to use UV_EINVAL.

LGTM. A test would be nice if possible.

Good point, added a test for this.

test/parallel/test-dgram-socket-buffer-size.js

+    type: Error,
+    message: new RegExp('^Could not get or set buffer' +
+      ' size: Error: EINVAL: invalid argument,' +
+      ' uv_' + type + '_buffer_size$')


Nit: I believe a string (instead of a regex) is enough to get exact matching here. You might want to use a template string instead of concatenation, I think we agreed on that preference.

I actually used a template for this but the linter complained which is why I changed it. I'll take another look though.

We usually use templates, except if the line becomes too long, in that case you can concatenate templates and string literals:

'Could not get or set buffer size: Error: EINVAL: ' + `invalid argument, uv_${type}_buffer_size`

Thanks, updated now.

+    code: 'ERR_SOCKET_BUFFER_SIZE',
+    type: Error,
+    message: `Could not get or set buffer size: Error: EINVAL: invalid argument, uv_${type}_buffer_size` // eslint-disable-line max-len


I think both of the long lines in this file could be handled without disabling the ESLint rule.

@jasnell Thanks for the heads up. I see the problem and will take a closer look. (I'm at a f2f this week so response times might not be that good)

@danbev seems like the CI is green now. Is this ready to land?

Looking into this I found won't work without

@danbev seems like the CI is green now. Is this ready to land?

Yep, it is good to go now. I can land it later this evening or tomorrow.

Should this be backported to v6.x-staging? If yes please follow the guide and raise a backport PR, if not let me know or add the dont-land-on label.
