* content: fixed repo upgrade version
Previously upgrade would enable epoch manager and index v2 but would
not set the version of the format itself. Everything worked fine
but it would not protect from old kopia opening the repository.
* ci: added compatibility test that uses real 0.8 and current binaries
* repo: added 'enable password change' flag (defaults to true for new repositories), which prevents embedding replicas of kopia.repository in pack blobs
* cli: added 'repo change-password' which can change the password of a connected repository
* repo: nit - renamed variables and functions dealing with key derivation
* repo: fixed cache validation HMAC secret to use stored HMAC secret instead of password-derived one
* cli: added test for repo change-password
* repo: negative cases for attempting to change password in an old repository
* Update cli/command_repository_change_password.go

* testing: ensure tests are releasing all buffer pools to reduce memory usage, we had huge leaks
* object: reduced complexity and memory usage of TestEndToEndReadAndSeekWithCompression
* manifest: more test fixes
* trivial: update comment

* manifest: removed explicit refresh
Instead, content manager is exposing a revision counter that changes
on each mutation or index change. Manifest manager will be invalidated
whenever this is encountered.
* server: refactored initialization API
* server: added unit tests for repository server APIs (HTTP and REST)
* server: ensure we don't upload contents that already exist
This saves bandwidth, since the client can compute hash locally
and ask the server whether the object exists before starting the upload.
* blob: refactored upload reporting
Instead of plumbing this through blob storage context, we are passing
and explicit callback that reports uploads as they happen.
* htmlui: improved counter presentation
* nit: added missing UI route which fixes Reload behavior on the Tasks page
- `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

content:Allow returning deleted content in GetContent
maintenance: check deleted contents as well
maintenance: test for when a directory content is reused after deletion
testing: add support for repo open options in repotesting
* Allow passing repo options to MustReopen
* Add repotesting.Environment.MustConnectOpenAnother
* Remove kopia.config.mlock file
* snapshot create helper
* Fix content delete related and e2e tests
Support for remote content repository where all contents and
manifests are fetched over HTTP(S) instead of locally
manipulating blob storage
* server: implement content and manifest access APIs
* apiclient: moved Kopia API client to separate package
* content: exposed content.ValidatePrefix()
* manifest: added JSON serialization attributes to EntryMetadata
* repo: changed repo.Open() to return Repository instead of *DirectRepository
* repo: added apiServerRepository
* cli: added 'kopia repository connect server'
This sets up repository connection via the API server instead of
directly-manipulated storage.
* server: add support for specifying a list of usernames/password via --htpasswd-file
* tests: added API server repository E2E test
* server: only return manifests (policies and snapshots) belonging to authenticated user
* This is 99% mechanical:
Extracted repo.Repository interface that only exposes high-level object and manifest management methods, but not blob nor content management.
Renamed old *repo.Repository to *repo.DirectRepository
Reviewed codebase to only depend on repo.Repository as much as possible, but added way for low-level CLI commands to use DirectRepository.
* PR fixes
This is mostly mechanical and changes how loggers are instantiated.
Logger is now associated with a context, passed around all methods,
(most methods had ctx, but had to add it in a few missing places).
By default Kopia does not produce any logs, but it can be overridden,
either locally for a nested context, by calling
ctx = logging.WithLogger(ctx, newLoggerFunc)
To override logs globally, call logging.SetDefaultLogger(newLoggerFunc)
This refactoring allowed removing dependency from Kopia repo
and go-logging library (the CLI still uses it, though).
It is now also possible to have all test methods emit logs using
t.Logf() so that they show up in failure reports, which should make
debugging of test failures suck less.
Also introduced strongly typed content.ID and manifest.ID (instead of string)
This aligns identifiers across all layers of repository:
blob.ID
content.ID
object.ID
manifest.ID
This updates the terminology everywhere - blocks become blobs and
`storage.Storage` becomes `blob.Storage`.
Also introduced blob.ID which is a specialized string type, that's
different from CABS block ID.
Also renamed CLI subcommands from `kopia storage` to `kopia blob`.
While at it introduced `block.ErrBlockNotFound` and
`object.ErrObjectNotFound` that do not leak from lower layers.
The splitter in question was depending on
github.com/silvasur/buzhash which is not licensed according to FOSSA bot
Switched to new faster implementation of buzhash, which is
unfortunately incompatible and will split the objects in different
places.
This change is be semi-breaking - old repositories can be read, but
when uploading large objects they will be re-uploaded where previously
they would be de-duped.
Also added 'benchmark splitters' subcommand and moved 'block cryptobenchmark'
subcommand to 'benchmark crypto'.
