Summary

This pull requests refactors the main calendar engine used by the mscalendar plugin and leverages the remotes implementation to allow other plugins to easily import this plugin providing its own remote to easily create other calendar plugins.

This work was done to create the mattermost-plugin-google-calendar that could be used as a template, with the caveheat that the google calendar plugin contains it's own frontend code to create events and that is currently not shared and it's a task to tackle in the future.

@fmartingr I've reopened this on a Mattermost-owned branch. Also notice that the base branch is gcal-master, which is currently equal to the master branch. 1/5 Let's use gcal-master as the protected branch for this project.

@fmartingr I gave the plugin a review, and noted some things within this commit d78381a. Note that the commit itself is the review. Please take a look and share any thoughts you might have.

I added some PR review comments on top of the commit, to gather info that is provider-specific. The goal is to put them all in one struct. I plan to search for these strings in the code to find more:

  • microsoft
  • msgraph
  • mscalender
  • mscal
  • gcal
  • google

I think the notification subscription lifecycle is the one thing that seems murky with regards to remaining work to handle both providers. I need to better understand gcal's subscription lifecycle to connect the dots on the code related to subscriptions.

Not really sure what's going on here. It seems like:

"If a setting is a boolean, create an event subscription if not exists"

This is notificationSetting.Set, so I suppose this is "I want to change notification settings". what do we do when the value hasn't changed? I suppose this function takes care of no-ops

Tested this PR.

2 commands, namely createevent and findmeetings do not have any functionality mentioned anywhere and is not clear after executing those commands as well.
Also, on adding any calendar through createcal, I am not able to find from where to add it in the Outlook window. Can you please have a look at those two and this issue?

Rest all are tested and approved from my side.

Thanks so much @AayushChaudhary0001. All 3 of those commands are generally unimplemented and should be removed from the codebase

@fmartingr It seems this PR has been approved by QA. Should we merge this and move forward with a release of this plugin, and also update the gcal plugin's commit to the next tag once created?

Yeah, apart from QA we did some testing ourselves back in the day, so I think this is good to go.

Considering this passed through QA and the Google Calendar plugin works from this, I'm giving my approval, but if we need a proper 2nd dev review I would add someone else, since we are the authors of this PR so my approval seems like cheating.
