Our CI needs to be able to fetch gx packages so some reachable IPFS node has to have them pinned locally (done).
Gx packages need to specify a dvcsImport path. Otherwise, path rewriting won't work. I've fixed up the gx packages so this should be fine now.

(basically, gx has a lot of rough edges we're working on ironing out).

Stebalien

Looking good but we'll definitely need some sharness tests. You'll probably want to add them to test/sharness/t0021-config.sh.

@Stebalien Thanks for your guidance. I find that /elgris/jsondiff doesn't support unmarshal. Should I write a new jsondiff lib to support this feat?

Stebalien · 2018-09-14T16:26:23Z

Hm. I see. Well, we have two options:

Send a []jsondiff.Item array (by calling diff.Items()) and then reconstruct the diff using diff.Add on the client. I'm not a fan of this approach...
Send back the old config and the new config and do the diff on the client. Personally, I'd rather do this.

That is, send back ConfigUpdateOutput { Old: OldConfig, New: NewConfig } and call jsondiff on the client. Does that sound reasonable? That's probably the most flexible solution.

qiwaa · 2018-09-17T07:02:19Z

@Stebalien Thx. The second method looks great and I use it. Could you help me review my code again?

Stebalien · 2018-09-19T20:44:11Z

@schomatis in an effort to "spread the love", I'm assigning you to review 😄.

schomatis

Feeling the love 😬

hey, @schomatis . I have completed modifications according to your advice. Could you help me review my code again? 😊

schomatis

Niiiiiicee, this is definitely much cleaner, thanks for taking the time to make those changes.

schomatis

Great, thanks!

qiwaa · 2018-10-09T02:44:26Z

@Stebalien Is there any other work that needs to be done? If so, please tell me.

Hard blocking the PR.

We changed other config commands to stop exposing Identity.PrivKey over HTTP API for security reasons. This command will also need to do that.

schomatis · 2018-10-09T14:28:09Z

@Kubuxu Could you expand some more on that please? How is this PR impacting security?

Kubuxu · 2018-10-09T17:45:57Z

In the past we hardened config endpoints not to return Identity.PrivKey because it is possible to break CORS protection and access API endpoint in some browsers.

This would reintroduce this risk.

schomatis · 2018-10-10T02:20:57Z

Oh, I see, the newly added diff output could expose sensitive information, makes sense, thanks.

qiwaa · 2018-10-10T05:10:50Z

This is a good suggestion. Thx a lot. I have updated the pr to stop exposing Identity.PrivKey over HTTP API.

Kubuxu · 2018-10-10T14:36:11Z

Thanks for resolving it quickly.

This fixes the data-race in the config. Depends on: ipfs/go-ipfs-config#16. This does not fix #4942 as there's still a logical race: parallel config updates clobber each other. However, we'll still need the Clone function for the new `--dry-run` flag introduced in #5455. License: MIT Signed-off-by: Steven Allen <steven@stebalien.com>

Stebalien · 2018-10-23T17:10:32Z

Blocked on #5455, unfortunately.

Stebalien · 2018-10-23T17:10:54Z

(that is, the dereference isn't sufficient to actually clone the config).

qiwaa · 2018-10-24T02:57:07Z

Maybe dereference is sufficient. Because config.Transformer, which is transformConfig' parameter , just updates map' point, not map' content. This does not affect the global config. Does that make sense?

Stebalien · 2018-10-24T12:41:55Z

I see. Yeah, this should work... (well, shouldn't be any worse than it already is).

Hey, @Stebalien . Thx for your review. If you need a better jsondiff lib in the future, ping me please. I am sure I will do this well.
