- `repo.Repository` is now read-only and only has methods that can be supported over kopia server
- `repo.RepositoryWriter` has read-write methods that can be supported over kopia server
- `repo.DirectRepository` is read-only and contains all methods of `repo.Repository` plus some low-level methods for data inspection
- `repo.DirectRepositoryWriter` contains write methods for `repo.DirectRepository`
- `repo.Reader` removed and merged with `repo.Repository`
- `repo.Writer` became `repo.RepositoryWriter`
- `*repo.DirectRepository` struct became `repo.DirectRepository`
interface
Getting `{Direct}RepositoryWriter` requires using `NewWriter()` or `NewDirectWriter()` on a read-only repository and multiple simultaneous writers are supported at the same time, each writing to their own indexes and pack blobs.
`repo.Open` returns `repo.Repository` (which is also `repo.RepositoryWriter`).
* content: removed implicit flush on content manager close
* repo: added tests for WriteSession() and implicit flush behavior
* invalidate manifest manager after write session
* cli: disable maintenance in 'kopia server start'
Server will close the repository before completing.
* repo: unconditionally close RepositoryWriter in {Direct,}WriteSession
* repo: added panic in case somebody tries to create RepositoryWriter after closing repository
- used atomic to manage SharedManager.closed
* removed stale example
* linter: fixed spurious failures
