Use non-formatting logging functions for message without formatting.
For example, `log.Info("message")` instead of `log.Infof("message")`
Configure linter for printf-like functions
* feat(server): reduce server refreshes of the repository
Previously each source would refresh itself from the repository
very frequently to determine the upcoming snapshot time. This change
refactors source manager so it does not own the repository connection
on its own but instead delegates all policy reads through the server.
Also introduces a new server scheduler that is responsible for
centrally managing the snapshot schedule and triggering snapshots
when they are due.

* feat(repository): apply retention policies server-side
This allows append-only snapshots where the client can never delete
arbitrary manifests and policies are maintained on the server.
The client only needs permissions to create snapshots in a given, which
automatically gives them permission to invoke the server-side method
for their own snapshots only.

Previously some logs from a running server were only kept in memory
(including storage activity logs) which was confusing to many folks.
This changes the behavior so that logs are sent to their regular
(console/file) file locations in addition to the UI tasks.
Old behavior can be restored by adding `--no-persistent-logs` to
server.
* feat(snapshots): added ability to use cron expressions to schedule snapshots
We use `github.com/hashicorp/cronexpr` to parse and evaluate expressions,
as documented in https://github.com/hashicorp/cronexpr#implementation
* upgrade ui
* pr feedback
* chore(ci): upgraded linter to 1.53.3
This flagged a bunch of unused parameters, so the PR is larger than
usual, but 99% mechanical.
* separate lint CI task
* run Lint in separate CI
This change adds a new streaming response to the FindManifests API. The
server will deliver the response in chunks of N manifests where N is
requested by the client. This allows the client to process the response
in chunks and improves pipelining of responses.
For now client will hold the entire response in memory since this
is what FindManifests() API currently does. This will be fixed in a
follow up change.
Replaces #2713Fixes#2660
Almost all were easy to replace, except ones exposed via JSON which
have been left as-is.
The linter has a cool behavior where it flags attempts to pass
`atomic.Int32` for example by value , which is always a mistake,
say as an argument to `fmt.Sprintf()`
This may be a breaking change for users who rely on particular kopia metrics (unlikely):
- introduced blob-level metrics:
* `kopia_blob_download_full_blob_bytes_total`
* `kopia_blob_download_partial_blob_bytes_total`
* `kopia_blob_upload_bytes_total`
* `kopia_blob_storage_latency_ms` - per-method latency distribution
* `kopia_blob_errors_total` - per-method error counter
- updated cache metrics to indicate particular cache
* `kopia_cache_hit_bytes_total{cache="CACHE_TYPE"}`
* `kopia_cache_hit_total{cache="CACHE_TYPE"}`
* `kopia_cache_malformed_total{cache="CACHE_TYPE"}`
* `kopia_cache_miss_total{cache="CACHE_TYPE"}`
* `kopia_cache_miss_errors_total{cache="CACHE_TYPE"}`
* `kopia_cache_miss_bytes_total{cache="CACHE_TYPE"}`
* `kopia_cache_store_errors_total{cache="CACHE_TYPE"}`
where `CACHE_TYPE` is one of `contents`, `metadata` or `index-blobs`
- reorganized and unified content-level metrics:
* `kopia_content_write_bytes_total`
* `kopia_content_write_duration_nanos_total`
* `kopia_content_compression_attempted_bytes_total`
* `kopia_content_compression_attempted_duration_nanos_total`
* `kopia_content_compression_savings_bytes_total`
* `kopia_content_compressible_bytes_total`
* `kopia_content_non_compressible_bytes_total`
* `kopia_content_after_compression_bytes_total`
* `kopia_content_decompressed_bytes_total`
* `kopia_content_decompressed_duration_nanos_total`
* `kopia_content_encrypted_bytes_total`
* `kopia_content_encrypted_duration_nanos_total`
* `kopia_content_hashed_bytes_total`
* `kopia_content_hashed_duration_nanos_total`
* `kopia_content_deduplicated_bytes_total`
* `kopia_content_read_bytes_total`
* `kopia_content_read_duration_nanos_total`
* `kopia_content_decrypted_bytes_total`
* `kopia_content_decrypted_duration_nanos_total`
* `kopia_content_uploaded_bytes_total`
Also introduced `internal/metrics` framework which constructs Prometheus metrics in a uniform way and will allow us to include some of these metrics in telemetry report in future PRs.
Lack of generics support is blocking various dependency upgrades,
so this unblocks that.
Temporarily disabled `checklocks` linter until it is fixed upstream.

Fixes#2372
* Make callback for upload file completion
Callback does not indicate that a file will be reachable immediately in
the resulting snapshot, but does indicate that the uploader is done
processing the file in some way (either via uploading data or finding a
previous version in the repo) and whether there was an error processing
the file.
* Tests for new FinishedFile callback
Ensure hadErr is properly populated and FinishedFile is called even if
the file was considered cached.
* Refine comment on interface function slightly
* Give callback error instead of bool about error
* Add locks around concurrent accesses in test
* refactor(repository): moved format blob management to separate package
This is completely mechanical, no behavior changes, only:
- moved types and functions to a new package
- adjusted visibility where needed
- added missing godoc
- renamed some identifiers to align with current usage
- mechanically converted some top-level functions into member functions
- fixed some mis-named variables
* refactor(repository): moved content.FormatingOptions to format.ContentFormat
Instead of passing static content.FormattingOptions (and caching it)
we now introduce an interface to provide its values.
This will allow the values to dynamically change at runtime in the
future to support cases like live migration.
Some compression algorithms are not recommended because they
allocate disproportionate amounts of memory. They are still
possible to use, just marked as NOT RECOMMENDED in the UI.
* Allow dynamic directory entries with virtualfs
* Tests for new virtualfs implementation
* Add escape hatch for estimator during upload
Some virtualfs.StreamingDirectory-s may not be able to (efficiently)
support iterating through entries multiple times. Make a way for the
estimator to ask if they support multiple iterations and skip the
directory if they do not.
* Exapand Directory interface
Expand the Directory interface instead of making a new interface as it's
error-prone to ensure all wrapper types properly handle types that use
the new interface.
* Post-rebase fixes
* Make StreamingDirectory single iteration only
Simplify code and test slightly by not allowing users to declare a
StreamingDirectory that can be iterated through multiple times.
* Add better test for estimator ignoring stream dir
Previous test in uploader had a race condition, meaning it may not catch
all cases.
* Ignore atomic access in checklocks
Comparisons known to be done after all additions to the variables in
question.
* Implement reviewer feedback
* Remove unused function parameter
* Unify sparse and normal IO output
This commit refactors the code paths that excercise normal and sparse
writing of restored content. The goal is to expose sparsefile.Copy()
and iocopy.Copy() to be interchangeable, thereby allowing us to wrap
or transform their behavior more easily in the future.
* Introduce getStreamCopier()
* Pull ioCopy() into getStreamCopier()
* Fix small nit in E2E test
We should be getting the block size of the destination file, not
the source file.
* Call stat.GetBlockSize() once per FilesystemOutput
A tiny refactor to pull this call out of the generated stream copier,
as the block size should not change from one file to the next within
a restore entry.
NOTE: as a side effect, if block size could not be found (an error
is returned), we will return the default stream copier instead of
letting the sparse copier fail. A warning will be logged, but this
error will not cause the restore to fail; it will proceed silently.
* refactor(repository): ensure we always parse content.ID and object.ID
This changes the types to be incompatible with string to prevent direct
conversion to and from string.
This has the additional benefit of reducing number of memory allocations
and bytes for all IDs.
content.ID went from 2 allocations to 1:
typical case 32 characters + 16 bytes per-string overhead
worst-case 65 characters + 16 bytes per-string overhead
now: 34 bytes
object.ID went from 2 allocations to 1:
typical case 32 characters + 16 bytes per-string overhead
worst-case 65 characters + 16 bytes per-string overhead
now: 36 bytes
* move index.{ID,IDRange} methods to separate files
* replaced index.IDFromHash with content.IDFromHash externally
* minor tweaks and additional tests
* Update repo/content/index/id_test.go

This was actually not producing invalid results because of how base36
works, just not sorting as efficiently as it could.
