Licensing plugin and XPackInfo uses the same license data #52507

mshustov · 2019-12-09T14:02:27Z

Summary

Closes: #52502
With this PR XPack doesn't fetch license data anymore, but consume them from NP Licensing plugin. To facilitate migration I converted XPack code into TypeScript.
I tested locally, but I would appreciate a review help to verify changes locally.
My main concern is createXPackInfo, which hasn't got any tests.

TODO: deprecate xpack.xpack_main.xpack_api_polling_frequency_millis when #52251 merged

That was removed in #51818 by mistake.
Xpack cannot detect license update without it. I also noticed that it doesn't work well with different fetching mechanism. Some plugins use NP fetch, some custom fetching mechanism, for example

axios
https://github.com/restrry/kibana/blob/354a152caa94d856b8ffe1fa4df0981421c1e134/x-pack/legacy/plugins/canvas/common/lib/fetch.ts#L10

We need to talk to solution teams about unifying the network stack.
@elastic/kibana-platform
Should we create a separate issue to track?

Do we want an issue, or should we 'just' add in our guidelines that the fetching mecanism in kibana should be core.http?

Apollo can be hard to migrate though, as it's not 'only' a fetch.

It seems we need to solve several problems:

to unify the network stack whenever possible

to investigate and document how we can integrate http interceptors in any network library. Apollo supports middlewares and afterwares https://www.apollographql.com/docs/react/networking/network-layer/#afterware
That could require adjusting interceptor API.

@chrisronline I need your help to test that it doesn't break https://github.com/elastic/kibana/blob/master/x-pack/legacy/plugins/monitoring/server/init_monitoring_xpack_info.js#L15
There are no tests to verify it

@restrry This LGTM. I pulled down the PR and the behavior seems consistent

Okay, so this actually wasn't the case. I missed something and this is causing a problem in 7.6

I removed all fetching tests. All remaining tests in the file are supposed to prove the xpack plugin contract.

temporarily adds tests for Legacy Licensing to have at least smoke-tests

Should we move this to a separate legacy test so it can be more easily deleted?

I wish we could. I need to add a comment in tests #51818 (comment)

I'm going to add a client side tests in the followup PR. Probably I just create 2 separate FTR configs for NP & LP

Should we have a licensingPluginMock in the licensing plugin and use it instead of inline declaration ? something like what's done in src/legacy/ui/public/new_platform/__mocks__/helpers.ts.

I will add a mock for NP the plugin.

This file uses Sinon instead of Jest. I don't want to provide the full mock because we are about to delete this setup completely.

Is this branch really needed? I would expect that license.error would be undefined when license.isActive is true anyways.

Yes, but this is this.cache._error, which is used by the legacy xpack plugin. Although it's not 1:1 mapping. The legacy plugin updated error whenever fetcher throws
