Leaves out modernize:omitempty due to conflicts with tests
Maintenance is critical for healthy of the repository.
On the other hand, Maintenance is complex, because
it runs multiple sub tasks each may generate different
results according to the maintenance policy.
The results may include deleting/combining/adding
data/metadata to the repository.
It is worthy to add more observability for these
tasks for below reasons:
It is helpful for troubleshooting. Any data change
to the repository is critical, the observability info
helps to understand what happened during the
maintenance and why that happened.
It is helpful for users to understand/predict the
repo's behavior. The repo data may be stored
in a public cloud for which costs are sensitive
to scale/duration of data stored. On the other
hand, repository has its own policy to manage
the data, so the data is not deleted until it is
safe enough according to the policy.
The observability info helps users to
understand how much data is in-use,
how much data is out of use and
when it is deleted
* Implement ability to extend retention time on S3 buckets using Object Locks
* Move object-lock extension to maintenance.Params.
* Use a default function for unsupported extensions instead of duplicating code
* Fix potential lockup during object-lock extension
* Fix race condition. Add more code coverage
* rebase to V3
* Add checks to prevent user from setting Retention Period < Full Maintenance Interval

The dual time measurement is described in
https://go.googlesource.com/proposal/+/master/design/12914-monotonic.md
The fix is to discard hidden monotonic time component of time.Time
by converting to unix time and back.
Reviewed usage of clock.Now() and replaced with timetrack.StartTimer()
when measuring time.
The problem in #1402 was that passage of time was measured using
the monotonic time and not wall clock time. When the computer goes
to sleep, monotonic time is still monotonic while wall clock time makes
a leap when the computer wakes up. This is the behavior that
epoch manager (and most other compontents in Kopia) rely upon.
Fixes#1402

* cli: include parameters in maintenance info JSON output
* e2e: add maintenance info checks in e2e test
* cli: simple test for 'maintenance info --json' command
* logging: added logger wrappers for Broadcast and Prefix
* nit: moved max hash size to a named constant
* content: added internal logger
* content: replaced context-based logging with explicit Loggers
This will capture the logger.Logger associated with the context when
the repository is opened and will reuse it for all logs instead of
creating new logger for each log message.
The new logger will also write logs to the internal logger in addition
to writing to a log file/console.
* cli: allow decrypting all blobs whose names start with _
* maintenance: added logs cleanup
* cli: commands to view logs
* cli: log selected command on each write session
cli: major refactoring of how CLI commands are registered
The goal is to eliminate flags as global variables to allow for better
testing. Each command and subcommand and most sets of flags are now
their own struct with 'setup()' methods that attached the flags or
subcommand to the provided parent.
This change is 94.3% mechanical, but is fully organic and hand-made.
* introduced cli.appServices interface which provides the environment in which commands run
* remove auto-maintenance global flag
* removed globals in memory_tracking.go
* removed globals from cli_progress.go
* removed globals from the update_check.go
* moved configPath into TheApp
* removed remaining globals from config.go
* refactored logfile to get rid of global variables
* removed 'app' global variable
* linter fixes
* fixed password_*.go build
* fixed BSD build
- `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

Globally replaced all use of time with internal 'clock' package
which provides indirection to time.Now()
Added support for faking clock in Kopia via KOPIA_FAKE_CLOCK_ENDPOINT
logfile: squelch annoying log message
testenv: added faketimeserver which serves time over HTTP
testing: added endurance test which tests kopia over long time scale
This creates kopia repository and simulates usage of Kopia over multiple
months (using accelerated fake time) to trigger effects that are only
visible after long time passage (maintenance, compactions, expirations).
The test is not used part of any test suite yet but will run in
post-submit mode only, preferably 24/7.
testing: refactored internal/clock to only support injection when
'testing' build tag is present
* maintenance: encrypt maintenance schedule block
* maintenance: created snapshotmaintenance package that wraps maintenance and performs snapshot GC + regular maintenance in one shot, used in CLI and server
* PR feedback.
* mechanical rename of package snapshot/gc => snapshot/snapshotgc
* maintenance: record maintenance run times and statuses
Also stopped dropping deleted contents during quick maintenance, since
doing this safely requires coordinating with snapshot GC which is
part of full maintenance.
* cli: 'maintenance info' outputs maintenance run history
* maintenance: only drop index entries when it's safe to do so
This is based on the timestamp of previous successful GC that's old
enough to resolve all race conditions between snapshot creation and GC.
* maintenance: added internal flush to RewriteContents() to better measure its time
Maintenance: support for automatic GC
Moved maintenance algorithms from 'cli' to 'repo/maintenance' package
Added support for CLI commands:
kopia gc - performs quick maintenance
kopia gc --full- perform full maintenance
Full maintenance performs snapshot gc, but it's not safe to do this automatically possibly in parallel to snapshots being taken. This will be addressed ~0.7 timeframe.
