* feat: support mTLS-only authn/authz with AccessControl and allow combining mTLS with other auth mechanisms
Signed-off-by: Ivan Arkhipov <me@endevir.ru>
* refactor: improve authentication logic and TLS certificate generation
- Fix mTLS authentication to use only leaf certificate instead of iterating
through all certificates in the chain
- Reject Authorization headers when corresponding auth method is disabled,
regardless of mTLS status (security improvement)
- Simplify authentication switch statement ordering and logic
- Move ErrUserDataNotFound error handling into sessionAuthn method
- Refactor TLS certificate generation to use Options pattern with
CertificateOptions struct for better extensibility
- Consolidate duplicate certificate generation code into helper functions
(generateCertificate, parseCA, initializeTemplate, applyOptions)
- Rename certificate generation functions for clarity:
- GenerateCertWithCN -> GenerateClientCert
- GenerateSelfSignedCertWithCN -> GenerateClientSelfSignedCert
- Add support for SAN settings including email addresses in certificates
- Update tests to reflect new authentication behavior and certificate API
This commit improves both the security posture (rejecting disabled auth
methods) and code maintainability (consolidated certificate generation).

What happens is:
- syncRef skips the image ("skipping image because it's already synced")
- syncReferrers doesn't sync anything
- CommitAll is still called even though nothing was synced
- The temp directory exists but is empty (no index.json, no blobs)
- CommitAll fails because index.json is missing
Let's ensure we properly check for errors, and skip the log messages if some of the cases.

Add validation to reject configuration files where stores and substores
of the same storage type (local or S3) have root directories that are
nested within each other or identical. Stores of different types (local
vs S3) are allowed to share the same root directory since they use
different storage backends.
The validation:
- Checks all stores (default + substores) for path conflicts
- Only compares stores of the same storage type
- Reports clear error messages indicating which stores conflict and why
Add comprehensive tests covering:
- Same storage types with identical/nested paths (rejected)
- Different storage types with same/nested paths (allowed)
- Various combinations of default store and substores
Fixes issues where nested or identical root directories could cause
data corruption or routing conflicts.

fix: error handling: return nil explicitly on successful completion
Several functions in pkg/meta/redis/redis.go were returning 'err' at the
end of successful execution paths, which could lead to incorrect error
handling when 'err' was overwritten in loops or conditionals.
Changed the following functions to return nil explicitly when all
operations succeed:
- SearchRepos: return nil instead of err after successful loop
- SearchTags: return nil instead of err after successful loop
- GetRepoMeta: return nil instead of err after successful operations
- GetImageMeta: return nil instead of err after successful operations
- GetReferrersInfo: return nil instead of err after successful loop
This ensures that when functions complete successfully, they explicitly
return nil rather than relying on the last value of err, which may have
been overwritten during execution. This fixes TestRedisUnreachable which
was failing because SearchRepos was incorrectly returning nil error when
Redis was unreachable.

fix(meta): handle cases where repositories when substores are nested
Note this is a case of bad configuration: having multiple stores
in the same tree structure. Guard against it in parse.go.
Fix getAllRepos to prevent duplicate repositories in metaDB when substore
directories are nested under the default store root directory.
The fix processes substores first, then the default store, using a
map-based deduplication approach to skip repositories that have already
been added. This ensures that when both the default store and substores
contain repositories with the same name (e.g., when a substore is nested
within the default store), only one instance is added to the repository
list.
Add test TestNoDuplicateReposWithSubstoresAndNestedRepoNames to verify
the deduplication logic works correctly with nested substores.
Also update the other tests to avoid these issues in the future
this is not a vali configuration.
This is not the intended use case for substores, and it may have caused:

When GetRepoLastUpdated fails (e.g., redis: nil), it returns time.Time{}
which gets converted to &time.Time{} (not nil). The existing nil checks
in sorting functions didn't account for zero time values, which should
also be treated as "oldest" (sorted last in descending order).

- Adds zero time checks in addition to existing nil checks

fix: make sure metadb statistics are initialized on image download, and minor metadb fixes for Docker v2 manifest compatibility
Looking into potential causes of https://github.com/project-zot/zot/issues/3163
1. One possible reason is the statistics were not properly initialized in the first place because of (unknown and/or unavoidable) errors on image push.
To workaround this add logic to initialize the statistics on the call to download them.
2. Some images have the download statistics while others dont, one cause could be a bug in the logic handling manifest mediatypes in the search extension.
Add compatibility checks for Docker v2 manifest types in metadb convert functions, and more tests for covering the Docker mediatype use case.
Side fixes:
- Ensure PushedBy Statistics entries are properly initialized in SetRepoReference
- Fix and issue in the image upload test functions, they were uploading docker images with oci mediatypes in call headers

feat: add verify-feature retention subcommand with comprehensive testing and validation
Add a `verify-feature retention` subcommand that allows users to preview and
validate retention policy changes without running the actual Zot server.
The command runs GC and retention tasks in dry-run mode for immediate feedback.
- Run verify-feature retention standalone without starting the server
- Preview retention policy decisions in dry-run mode
- Configurable GC interval override via command-line flag
- Optional timeout for task completion
- Configurable log output (stdout or file)
Basic usage:
```bash
zot verify-feature retention <config-file>
```
With log file output:
```bash
zot verify-feature retention -l /var/log/zot-retention-check.log <config-file>
```
With GC interval override (runs GC tasks every 30 seconds):
```bash
zot verify-feature retention -i 30s <config-file>
```
With timeout (wait up to 5 minutes for tasks to complete):
```bash
zot verify-feature retention -t 5m <config-file>
```
Combined flags:
```bash
zot verify-feature retention -l /var/log/zot-retention-check.log -i 1m -t 10m <config-file>
```
The command supports overriding GC settings from the config:
- `-i, --gc-interval`: Override the GC interval setting (applies to all storage paths including subpaths)
- Refactored `RunGCTasks` from `controller.go` to be reusable
- Added `checkServerRunning` validation to prevent conflicts
- Implemented signal handling for graceful shutdown
- Added configuration sanitization and logging
- Set GCMaxSchedulerDelay programmatically (not user-configurable)
Added tests for coverage on main function:
- Negative test cases (no args, bad config, GC disabled, server running)
- Both BoltDB and Redis
- Retention enabled scenarios with complex image setups
- Retention disabled scenarios
- Delete referrers functionality
- Subpaths configuration
- GC interval override validation
Run the verify-feature retention tests:
```bash
go test -v ./pkg/cli/server -run TestRetentionCheck

Make the Secure flag for session cookies configurable based on Zot's
TLS settings. This allows cookies to work properly when Zot is
accessed over HTTP (without TLS).
Changes:
- Add SecureSession field to AuthConfig to allow explicit control
- Add UseSecureSession() method that returns true when TLS is
configured, or uses SecureSession setting if provided
- Update saveUserLoggedSession() to accept and use secure parameter
- Add tests for UseSecureSession() in config_test.go
- Enhance authn tests to verify cookie Secure flag behavior
- Fix TestAuthnSessionErrors by creating new client without cookies
The logic is:
- If TLS is configured, cookies always have Secure=true
- If TLS is not configured but SecureSession is explicitly set,
use that value
- Otherwise, default to Secure=false for HTTP-only deployments

* fix: make config read/write thread safe and fix some other similar issues
1. The config config has a lock, and safe methods to update and read the attributes
2. The config has methods to retrieve copies of specific attributes, such as the extyensions config, the auth config, and the authz config.
These are needed, as the config object may mutate in the middle of an auth/authz requests, and we avoid partial configuration being applied for that request.
3. Fix an issue with the monitoring server not stopping when the controller is shut down.
4. Fix an issue with the HTPasswdWatcher not stopping when the background tasks are supposed to finish.
5. Fix some tests using hardcoded ports.

* fix: migrate to Go module v2 for proper semantic versioning
This change updates the module path from 'zotregistry.dev/zot' to
'zotregistry.dev/zot/v2' to comply with Go's semantic versioning rules.
According to Go's module versioning requirements, major version v2+
must include the major version in the module path. The current
module path 'zotregistry.dev/zot' only supports v0.x.x and v1.x.x
versions, making existing v2.x.x tags (like v2.1.8) unusable.
Changes:
- Updated go.mod module path to zotregistry.dev/zot/v2
- Updated all internal import paths across 280+ Go source files
- Updated configuration files (golangcilint.yaml, gqlgen.yml)
- Updated README.md Go reference badge
This fix enables proper use of existing v2.x.x Git tags and allows
external packages to import zot v2+ versions without compatibility
errors.

Most users don't make the difference between retention deleting untagged manifests vs GC deleting other blobs.
This causes confusion since the GC delay and the retention delay (used for untagged manifests and orphan referrers) have different defaults, and are set separately in the zot configuration.
Most users don't configrue retention policies, and they still expect untagged manifests to be deleted at GC time.
With this change, if retention delay is not specified in the config file, the value used is the GC delay.
If GC delay is also unspecified in the config file, the default GC delay is used for both.

Description
====================
zot currently stores session cookies in memory or in a local directory.
For cases where the session cookies should be independent of the
instance where they were created such as multiple instances of zot, or a
fully stateless zot instance, there is a need to support a remote
session storage.
This change adds support for using Redis and Redis-compatible services as a
remote session driver as well as introduces a new configuration option
for it.
What has changed
=======================
- New config added under Auth config to specify configuration for
the session driver.
- Examples README updated with details of the new Auth config.
- The config supports only 2 drivers in this change - local and redis
- Using the local driver is backwards compatible and behaves the same
way that zot currently works for local session storage.
- Omitting this config does not result in an error. In this case, zot
behaves as it normally does for local session storage.
- When configured, zot can use redis for persisting cookie
information for zot UI.
- The cookie in the store is deleted on logout or after the max
expiry time for the cookie.
- Configuration for the redis session driver accepts the same configuration
values as that of the remote meta cache.
- A separate connection is established for the session driver. An
existing connection for meta cache will not be re-used for the
session driver.
- A key prefix is configurable for the redis session driver. The value will be
converted into a string for use. If no value is provided, a default
prefix of "zotsession" will be used.
- Redis sessions does not support hash key or encryption in this change.
- New BATS test added to verify zot behavior with Redis session store.
- Github workflow updated to install valkey-tools dependency for BATS.
