Consistent error messages in all modules by micnic · Pull Request #892 · nodejs/node

micnic · 2015-02-19T15:50:07Z

This commit fixes some error messages that are not consistent with
some general rules which most of error messages follow.

cjihrig · 2015-02-19T15:54:35Z

lib/timers.js

"non-negative" and "positive" are not quite the same thing.

I used "positive" to fit in 80 characters line length, but I can switch it back

Probably best to split the string then.

I'm +1 on standardizing error messages. My only real question is, have we actually defined a standard for this? Based on this PR, it looks like it would be to capitalize at the beginning of the message, and to put argument names in double quotes.

piscisaureus · 2015-02-19T16:03:26Z

+1 on the idea of standardizing error messages.
Maybe it's good to discuss a template for them first?

Just a couple I run into:

Error: connect ENOENT does.not.exist
Error: getaddrinfo ENOTFOUND does.not.exist.com does.not.exist.com:81
Error: ENOENT: no such file or directory, open 'C:\Users\Bert Belder\bar\baz'
RangeError: port should be > 0 and < 65536: 0

lib/smalloc.js

I think this should be "n" should be less or equal than "kMaxLength"

"less than or equal to"?

That's even better!

timoxley · 2015-03-19T20:26:12Z

Perhaps this is for another PR, but perhaps should make the usage of "should" vs "must" consistent – currently they seem to be used interchangeably:

e.g.

throw new TypeError('"options" argument must be an object');

vs

throw new TypeError('"curve" argument should be a string');

I'd suggest that once the code is throwing an assertion error it's out of the jurisdiction of a "should" and into the hands of "must", though perhaps "must" sounds a little pushy so perhaps io.js could optimise for developer feels and give people an illusion of choice with the calm & assertive "should".

Some related literature http://www.differencebetween.net/language/grammar-language/difference-between-should-and-must/

edit: I suggest following these common definitions used by RFCs in "Key word for use in RFCs to Indicate Requirement Levels": https://tools.ietf.org/html/rfc2119

bnoordhuis · 2015-03-20T15:50:54Z

I'm in favor of "must". Followed by "Or else."

lib/_http_outgoing.js

required -> is required

I'd also say that we shouldn't replace "name" with the actual value of the variable

ronkorving · 2015-07-11T09:02:49Z

lib/_http_outgoing.js

Nowhere (except in this file) do your error messages end with a period.

ronkorving · 2015-08-10T10:31:08Z

Is this still going places?

thefourtheye · 2015-08-10T11:36:27Z

Looks like this is favoured. Can you please rebase and address the comments?

@thefourtheye, forgot about this PR, sorry :P
rebased and took in count all the comments added

Trott · 2015-08-10T17:32:09Z

LGTM if it passes CI. 👍

Maybe @nodejs/documentation can find an appropriate place for a minimal Error message standardization doc based on the existing error messages (if such a doc doesn't already exist). Just to get it off the ground, the doc might only contains the two things @cjihrig notes (double quotes, capitalize first word unless there's a compelling reason not to such as it is a case-sensitive variable name) along with a note about omitting final punctuation.

I would prefer a standard that had punctuation at the end and made verbs explicit (e.g., Index is out of range. rather than Index out of range) but consistency is way more important than my own somewhat arbitrary preferences.

thefourtheye · 2015-08-10T17:51:01Z

Hmmm, this should be targeted at master

r-52 · 2015-08-10T17:52:31Z

lib/crypto.js

Small question: Every other error is something line ".... must be ...". Does it make sense to change it also in crypto?

We don't have a compromise on this yet (should vs must) see https://tools.ietf.org/html/rfc2119

jasnell · 2015-10-14T18:38:02Z

@micnic ... in general this is a good step but it definitely needs to be targeted at master and rebased. It won't be able to land as is.
