missing error.path at fs.mkdir callback on last call

[thisconnect]

Expected to always have an Error with errno, code, syscall and path.

In the following 2 examples one error contains path and the other one doesn't.

• Version: v12.3.1
• Platform: Darwin computer.local 18.6.0 Darwin Kernel Version 18.6.0: Thu Apr 25 23:16:27 PDT 2019; root:xnu-4903.261.4~2/RELEASE_X86_64 x86_64
• Subsystem: fs

const fs = require('fs');
fs.writeFileSync('./test2.txt', '');

// missing error.path
fs.mkdir('./test2.txt/sub/dir/dir/dir', {
 recursive: true
}, function(err) {
 console.log('\n\nerr', err)
 console.log('with recursive:true error is MISSING err.path', err.path)
});

// error.path ok
fs.mkdir('./test2.txt/sub/dir/dir/dir', {
 recursive: false
}, function(err) {
 console.log('\n\nerr', err)
 console.log('with recursive:false err.path is', err.path)
});

I believe this was working with older node 10.x versions, possibly related to a change in #27198

Output:

err [Error: ENOTDIR: not a directory, mkdir './test2.txt/sub/dir/dir/dir']{
 errno: -20,
 code: 'ENOTDIR',
 syscall: 'mkdir',
 path: './test2.txt/sub/dir/dir/dir'
}
with recursive:false err.path is ./test2.txt/sub/dir/dir/dir


err [Error: ENOTDIR: not a directory, mkdir]{
 errno: -20,
 code: 'ENOTDIR',
 syscall: 'mkdir'
}
with recursive:true error is MISSING err.path undefined

fs.writeFileSync('./test2.txt', ''); is the culprit

[himself65]

const fs = require('fs')
fs.writeFileSync('./text', '')
fs.mkdirSync('./text')

}

In the Unix platform, we cannot create the file and folder which are the same name, because everything is a file in Unix.

what's more, if we really create it, what's the happened in this example?

const fs = require('fs')
fs.writeFileSync('./text', '')
fs.mkdirSync('./text')

// what will happened here???
fs.statSync('./text')

In the Windows platform, I think it's the same reason

AfterNoArgs, mkdirp ? MKDirpAsync : uv_fs_mkdir, *path, mode);

and when make dir loop call MKDirpAsync

[himself65]

const fs = require('fs')
fs.writeFileSync('./foo', '')
try {
 fs.mkdirSync('./foo/foo/foo', { recursive: true })
} catch (e) {
 console.log(e)
 console.log(e.path)
}
console.log('\n\n\n')
fs.mkdir('./foo/foo/foo', { recursive: true }, (e) => {
 console.log(e)
 console.log(e.path)
})

correct, but the issue is only about that path is missing in this error. I update the description. Sorry I should have written a better description.

[himself65]

i get it. and I believe something escaped this line

node/src/node_file.cc

Line 1402 in e8f3119

AfterNoArgs, mkdirp ? MKDirpAsync : uv_fs_mkdir, *path, mode);

[himself65]

const assert = require('assert')
const fs = require('fs')
const path = require('path')
const file = path.join(__dirname, 'foo')
const dir = path.join(file, './foo/foo')

fs.writeFileSync(file, '')
fs.mkdir(dir, { recursive: true }, function (err) {
 console.log(err)
})

fs.mkdir(dir, { recursive: false }, function (err) {
 console.log(err)
})
fs.mkdir(dir, { recursive: false }, function (err) {
 console.log(err)
})
fs.mkdir(dir, { recursive: false }, function (err) {
 console.log(err)
})
fs.mkdir(dir, { recursive: false }, function (err) {
 console.log(err)
})

I think the actual bug is a missing path on last call

[himself65]

so, this issue title should change to missing error.path at fs.mkdir callback on last call
