* 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
* testing: KOPIA_TEST_LOG_OUTPUT logs subcommand outputs
* cli: additional flags for 'blob list'
* Makefile: run all tests against epoch-based index manager
* epoch: added support for deletion watermark, which keeps track of latest maintenance which dropped index entries
* content: added deletion watermark to content manager
* maintenance: improved maintenance without safety to force rewrites
* maintenance: skip quick maintenance when epoch manager is enabled
* maintenance: do not enable quick maintenance when epoch manager is used
* testing: skip TestIndexOptimize when running against epoch manager-backed index strutures
* cli: added 'repository validate-provider' which runs a set of tests against blob storage provider to validate it
This implements a provider tests which exercises subtle behaviors which are not always correctly implemented by providers claiming compatibility with S3, for example.
The test checks:
- not found behavior
- prefix scans
- timestamps
- write atomicity
* retry: improved error message on failure
* rclone: fixed stats reporting and awaiting for completion
* webdav: prevent panic when attempting to mkdir with empty name
* testing: run providervalidation.ValidateProvider as part of regular provider tests
* cli: print a recommendation to validate provider after repository creation
* testing: removed testutil.Retry because all providers now have internal retries
* testing: simplified and unified cleanup for all cloud providers using shared buckets
* 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

* repo: big performance improvement for WriteContent with repo server
When re-uploading previously snapshotted directory we fetch directory
content `k<hash>` and very frequently end up writing the exact same
content. By caching last N content IDs we can avoid costly round-trip
to the server since we know that content ID was present in the session.
Also added small number of asynchronous writes, which also helps with
upload performance. Background writes are awaited before Flush().
Performance when snapshotting lots of small files (source code):
31.9 GB files:471205 dirs:75817, warm cache
Before: 260s
After: 55s (4-5x faster)
* fixed tests
* epoch: misc fixes and logging
* blob: misc helpers
* cli: removed useless 'repository upgrade', replaced by 'repository set-parameters'
* content: implemented indexBlobManagerV1 which uses epoch manager
* cli: commands to manipulate repository epoch parameters
* cli: commands to examine epoch-based indexes
* content: added test suite that uses epoch-based index manager
* content: fixed a ton of test data races caused by sharing blobtesting.DataMap
* cli: additional tests and validation for 'repository set-params'
* testing: replaced the use of suite with our own, since suite is not parallelizable
* refactor: extracted complete blob set functions to separate package
* completeset: added more functions
Also treat malformed blob IDs as their own sets for backwards compat.
* testing: refactored logs directory management
* content: fixed index mutex to be shared across all write sessions
added mutex protection during writecontent/refresh race
* testing: upload log artifacts
* content: bump revision number after index has been added
This fixes a bug where manifest manager in another session for
the same open repository may not see a content added, because they
will prematurely cache the incomplete set of contents.
This took 2 weeks to find.
* manifest: improved log output, fixed unnecessary mutex release
* testing: rewrote stress test to be model-based and more precise
* trivial: refactored indexBlobManager interface
* testlogging: added NewLogger()
* blob: added helper to extract blob IDs
* content: added packIndexBuilder.BuildStable()
This uncovered a bug where we were failing to return the name of
last pack object ID in an index file. Because of padding this was never
possible, but with stable indexes will. Fixed that.
* cli: added a flag to create repository with v2 index features
* content: plumb through compression.ID parameter to content.Manager.WriteContent()
* content: expose content.Manager.SupportsContentCompression
This allows object manager to decide whether to create compressed object
or let the content manager do it.
* object: if compression is requested and the repo supports it, pass compression ID to the content manager
* cli: show compression status in 'repository status'
* cli: output compression information in 'content list' and 'content stats'
* content: compression and decompression support
* content: unit tests for compression
* object: compression tests
* testing: added integration tests against v2 index
* testing: run all e2e tests with and without content-level compression
* htmlui: added UI for specifying index format on creation
* cli: additional tests for 'content ls' and 'content stats'
* applied pr suggestions
* cli: Added --max-examples-per-bucket flag to 'kopia snapshot estimate'
Added and cleaned up a bunch of unit tests.
Fixes#1054
* cli: misc tests to increase code coverage of the cli package
* ci: move code coverage run into separate GH job
* cli: fixed remaining testability indirections for output and logging
* cli: added cli.RunSubcommand() which is used in testing to execute a subcommand in the same process
* tests: refactored most e2e tests to invoke kopia subcommands in-process
* Makefile: enable code coverage for cli/ and internal/
* testing: pass 'testing' tag to unit tests which uses much faster (insecure) password hashing scheme
* Makefile: push coverage from PRs again
* tests: disable buffer management to reduce memory usage on ARM
* cli: fixed misaligned atomic field on ARMHF
also temporarily fixed statup-time benign race condition when setting
default on the timeZone variable, which is the last global variable.
* introduced passwordpersist package which has password persistence
strategies (keyring, file, none, multiple) with possibility of adding
more in the future.
* moved all password persistence logic out of 'repo'
* removed global variable repo.EnableKeyRing
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
