fs: default open/openSync flags argument to 'r' #23767

bnoordhuis · 2018-10-19T21:07:35Z

Make fs.open() and fs.openSync() more economic to use by making the
flags argument optional. You can now write:

fs.open(file, cb)

Instead of the more verbose:

fs.open(file, 'r', cb)

This idiom is already supported by functions like fs.readFile().

LGTM. What would the semver-iness of this be? minor?

Nits:

Missing period.

One unneeded space in the next line indent alignment,

It seems our common style is to place **Default:** notes at the end of a parameter description:

* `flags` {string|number} See [support of file system `flags`][]. **Default:** `'r'`.

Should the fsPromises.open(path, flags[, mode]) be unified?

Suggested change

## fs.open(path[, flags, mode], callback)

## fs.open(path[, flags[, mode]], callback)

Is this a style we use elsewhere? It looks unfamiliar to me.

Yes, see https://nodejs.org/api/buffer.html#buffer_buf_fill_value_offset_end_encoding for example.

The [, flags[, mode]], is the right doc convention, and looks to agree with how it is now implemented.

Updated based on feedback:

doc nits
updated fs.promises.open()

refack · 2018-10-23T21:50:41Z

Is this semver minor or major? i.e. could any existing code break?

Yes, minor.

Test failure is #23807 and unrelated (wasn't fixed yet when the CI was started.)

Trott · 2018-10-26T03:04:19Z

Last CI was green. Any reason this shouldn't land?

lpinca · 2018-10-26T05:35:08Z

I think this can land, my nit can be addressed in another PR if wanted.

Trott · 2018-10-26T05:57:26Z

Applied the nit.
