fix(core/components/dag): make options in `put` API optional #1415

0x-r4bbit · 2018-06-29T15:51:22Z

The dag.put interface
takes an options object which is required, but should be optional with
decent defaults.

See dedicated test here: ipfs-inactive/interface-js-ipfs-core#316

This commit implements this behaviour.

Before:

ipfs.dag.put(obj, options, (err, cid) => {...});

^ Prior to this commit, without passing options, this call resulted in an error.

After:

ipfs.dag.put(obj, (err, cid) => {...});

^ This is now perfectly fine.

Fixes #1395

@alanshaw you might wanna review those.

These should be the same as go-ipfs (https://ipfs.io/docs/commands/#ipfs-dag-put) i.e. dag-cbor and sha2-256

Note also that cid can be passed here instead of format & hashAlg that you need to take into account. See https://github.com/ipfs/interface-ipfs-core/blob/master/SPEC/DAG.md#dagput

This is my first take on fixing #1395

I also wrote simple test for it in interface-ipfs-core, however, I wasn't able to actually run it within my local js-ipfs installation yet.

That's because as soon as interface-ipfs-core is linked as a dependency, test commands fail due to createCommon() not being a function.

Here's the error message I get:

I took a closer look and createCommon should've actually been passed down from test/core/interface/bitswap.js:

https://github.com/ipfs/js-ipfs/blob/master/test/core/interface/bitswap.js#L35

@alanshaw maybe you have an idea what could cause this. I should add that this error does not occur when not linking interface-ipfs-core.

0x-r4bbit · 2018-06-29T15:59:39Z

Also, I wasn't sure about the commit message scope, let me know if that needs to be updated.

travisperson · 2018-06-29T19:24:03Z

@PascalPrecht PR #1389 updates js-ipfs to work with the newer version of interface-ipfs-core, which now requires the common to be a function stead of just an object.

To run new interface-ipfs-core (where your test is built), you will need to rebase your changes in this branch onto #1389.

PR #1389 should be merging soon, so we'll just need to wait for that to go in before merging this PR.

0x-r4bbit · 2018-06-29T21:27:33Z

@travisperson thanks for clarifying!

I thought the #1389 was only crucial to enable support for the API to skip testsuites as @alanshaw mentioned in #1395.

Also I've just noticed that js-ipfs sits on interface-ipfs-core version 0.69.0 which explains the incompatibility between those to packages on latest master, as interface-ipfs-core has already evolved since then.

I'll rebase this PR on top of it then.

Thanks again for clarifying!

@travisperson @alanshaw Updated the PR accordingly.

I've also created another PR on interface-ipfs-core to introduce a dedicated test: ipfs-inactive/interface-js-ipfs-core#316

We might wanna merge that one, before this one can go in.

Looks like CI is failing due to use of object spread operators. Will update the PR once again to make CI happy.

0x-r4bbit · 2018-06-30T08:39:10Z

Went with Object.assign() instead of object spread operators now. Hope that will satisfy CI.

CI is still failing, but those failing tests are unrelated to my changes.

I've also noticed that this needs to be implemented in js-ipfs-api as well (https://github.com/ipfs/js-ipfs-api/blob/master/src/dag/put.js#L18). Will wait once we've decided on decent defaults and send a PR over there as well.

These should be the same as go-ipfs (https://ipfs.io/docs/commands/#ipfs-dag-put) i.e. dag-cbor and sha2-256

Note also that cid can be passed here instead of format & hashAlg that you need to take into account. See https://github.com/ipfs/interface-ipfs-core/blob/master/SPEC/DAG.md#dagput

Note also that cid can be passed here instead of format & hashAlg that you need to take into account.

@alanshaw good point. The spec doesn't say anything about it, but I guess it'd make sense to throw an error in case someone uses the API wrong.

Or would you prefer if dag.put would silently chose an option with higher priority? For example, if cid is given, it simply ignores format and hashAlg.

alanshaw · 2018-07-02T10:58:37Z

The spec doesn't say anything about it

I'm looking here:

If the user passes a cid along with a format or hashAlg then I think it should callback with an error. It is likely developer error and we should inform them about it.

I'd also enforce format and hashAlg pair i.e. you shouldn't be able to pass one but not the other.

Does that sound sensible?

0x-r4bbit · 2018-07-02T11:00:59Z

I'm looking here

Correct! I was referring to whether the API should throw an error or not :)

Does that sound sensible?

Alright, gonna update the PR once again!

For a moment I was confused whether throwing synchronously inside promisify() makes sense, but I don't seem to have a handle to "reject" it either.

Looking at its testsuite, it seems to be the way to go: https://github.com/manuel-di-iorio/promisify-es6/blob/master/test.js#L79

I would replace throw new ... with return callback(new ...)

@richardschneider thanks for the hint! I assume that will automatically reject the promise?

I've updated the PR accordingly either way :)

This is awesome 🚀 @PascalPrecht - thanks so much. I have just one small feedback point and we should be good to merge.

If we change this to if (options.cid && (options.format || options.hashAlg)) we'll catch cid+format, cid+hashAlg AND cid+format+hashAlg. At the moment if I provide one of hashAlg or format as well as cid it'll fall through to the next check which is for a different restriction.

Sorry, yes I completely missed that - you must return callback(new Error(...)) for these

Done! Sorry I didn't come up with callback(new Error()) myself. It wasn't really clear, looking at the (minimal) docs and tests of promisify-es6.

This should be aligned now.
