I suspect this principle has been decided previously, but maybe not?:

Is it desirable to have such specific codes? Why not just ERR_INVALID_ARG_VALUE?

it's been debated and I'm good with it either way.

I'd be in favor of erring on the side of more general and you can always move to a more specific code later if it turns out it's really needed. But yeah, if there's fierce opinions on both sides, then ¯\(ツ)/¯

lib/fs.js

ERR_OUT_OF_RANGE is reduced into ERR_VALUE_OUT_OF_RANGE in #17648. So here would be better to use ERR_VALUE_OUT_OF_RANGE.

yep, was holding off a bit to see if/when #17648 was going to land.

oh.. right, and the latest updates remove the out of range errors anyway so this is no longer relevant ;-)

lib/internal/errors.js

It would justify this new error a bit more if the error message includes a list of valid symlink types

jasnell · 2017-12-18T18:55:10Z

Chose to go with @joyeecheung's suggestion of a more specific error message. PTAL

+                               ['string', 'Buffer', 'URL']);

+  if (!Number.isInteger(uid))


Should we also check for uid >= 0? Same question for the other checks in this commit

I do believe that uid and gid both can be negative in some edge cases.

General question about Number.isInteger checks: the check passes for values > 2^31-1 in JS land but not in C++ land. Should we guard for this?

LGTM with the nits already noted addresses

the check passes for values > 2^31-1 in JS land but not in C++ land

Replacing IsInt32() and IsUint32() checks with Number.isInteger() is wrong. Their JS equivalents are x === x | 0 and x === x >>> 0 respectively.

Another issue with Number.isInteger() is that users can monkey-patch it.

jasnell · 2017-12-21T18:28:35Z

Updated to address @bnoordhuis' feedback.

@mcollina and @joyeecheung ... please take another look.

IsInt32 (both lines)

FChown is not changed in this PR and also gets Uint32Value(). Are you sure negative uid and gid are possible?

hmm... they are definitely theoretically possible but you're right. I'll keep these as uint32s

@jasnell it looks like the new assertions in src/node_file.cc are causing some CitGM issues. Would you mind having a look? https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1165/

joyeecheung · 2017-12-24T20:57:09Z

@apapirovski The CITGM issues are caused by fs.readFile and fs.exists/fs.existsSync raising assertion when the path is undefined. I have a fix coming up.
