Deprecate Instant.period #1142

Closed bonjourmauko closed 2 years ago

bonjourmauko commented 2 years ago

Depends on #1160

Deprecations

In periods.Instant:
- Remove period, method used to build a Period from an Instant.
- This method created an upward circular dependency between Instant and Period causing lots of trouble.
- The functionality is still provided by periods.period and the Period constructor.

Migration details

Replace some_period.start.period and similar methods with Period((unit, some_period.start, 1)).

I will postpone reviewing this PR until the one it depends on is approved, and suggest that this one is set to draft. Indeed, I fail to see how it could be approved when #1141 might not go through.

Do you truly need #1141 for this one to be reviewed? 🙂 As an alternative to switching to draft, I suggest to remove the dependency and rebase straight on master. Yes, test-docs might fail until #1141 is fixed, but that is true of all PRs, not only of this one. This would enable reviews to be parallelised and proper solutions found for #1140 without blocking all the others.
