fs: bad error message in fs.openSync #2871
Description
Calling:
fs.openSync(path, { flags: 'w' });Throws: TypeError: flags must be an int from native land.
While on the C++ side, that may be correct, in JavaScript land, the 2nd argument is not an int but a string.
In other words, yes, me passing an object was bad, but the error informed me to do the wrong thing compared to what the docs say.

fsflags are a string, not object, like goingrequire('fs').readFile(dude, 'utf8', cb)reqshark commentedon Sep 15, 2015
but yea the error definitely says
intwhen you give it objectsyjhjstz commentedon Sep 15, 2015
should we throw
new Error('Unknown file open flag: ' + flag);instringToFlags?ronkorving commentedon Sep 15, 2015
I think it should throw a
TypeErrorif not string and not integer (Number.isIntegeris now at our disposal). However, this is also used in the asynchronousfs.open, so we need to be careful with exceptions.In fact, I just realized that's already broken in
fs.openandfs.readFile, sincestringToFlagsalready throws. See Line 251 and Line 541.ronkorving commentedon Sep 15, 2015
I'll conjure up a PR to fix this.
