The barman-cloud plugin experienced significant performance degradation
and memory growth compared to the embedded solution. WAL archiving was
noticeably slower and memory consumption grew over time.
Root cause: The sidecar uses a read-only filesystem which prevents
Python from creating bytecode at runtime. When Python finds missing or
stale bytecode (.pyc files), it attempts to recompile on every
invocation, causing high CPU usage and memory consumption. The previous
approach pre-compiled bytecode in a separate base image, but the
bytecode was marked as stale when copied between Docker stages,
triggering runtime recompilation attempts.
This change eliminates bytecode staleness by ensuring all Python
bytecode is properly compiled in the final image before the sidecar
starts. The image is now fully distroless and based on trixie
(previously it was distroless-based but copied unnecessary files from
the build stage), reducing size from 463MB to 270MB and package count
from 188 to 35, while maintaining zero HIGH/CRITICAL vulnerabilities.

Pin all e2e test emulator images to specific SHA256 digests to ensure
immutability and prevent unexpected breakage from upstream changes.
The three emulators (Azurite for Azure, MinIO for S3, and
fake-gcs-server for GCS) were previously using the :latest tag, which
could cause test failures when new versions with breaking changes or
bugs were released.
Using SHA256 digests instead of version tags provides immutability
(ensures we always pull the exact same image), transparency (easy to
verify what's running via digest comparison), and Renovate compatibility
(can still track and propose updates). All pinned SHAs match the current
:latest tag, confirming we're using the same images that were previously
tested.
Updated Renovate configuration to track digest-based updates while
preserving version information in comments for human readability. Fixed
Renovate to scan test directories and handle multi-line regex patterns
for .go files.
Also fixed Azurite compatibility issue by adding the
--skipApiVersionCheck flag. Tests were failing because the PostgreSQL
container images install Python dependencies without version pinning,
which resulted in azure-storage-blob 12.28.0 (released January 6, 2026)
being installed. This version uses API version 2026-02-06 which Azurite
3.35.0 doesn't support yet. The flag allows Azurite to accept any API
version in the test environment.
Note that MinIO is now in maintenance mode and will not receive further
updates, but it has been included for completeness.

Pin crd-ref-docs to v0.2.0 (latest stable release) instead of using the
master branch. This prevents issues from upstream changes and provides
better control over when to adopt new versions.
Configure Renovate to automatically track and update the version,
allowing us to review and test changes before merging.

This PR adds a disclaimer to the object stores documentation clarifying
that the Barman Cloud Plugin does not independently test all
authentication methods supported by barman-cloud. The plugin's
responsibility is limited to passing the provided credentials to
barman-cloud, which then handles authentication according to its own
implementation.
This documentation change was decided by the maintainers as part of the
discussion around Azure Default Credentials support (#662).

This commit adds support for the DefaultAzureCredential authentication
mechanism in Azure Blob Storage. Users can now use the
`useDefaultAzureCredentials` option to enable Azure's default credential
chain, which automatically discovers and uses available credentials in
the following order
1. Environment Variables (Service Principal)
2. Managed Identity
3. Azure CLI
4. Azure PowerShell
This is particularly useful when running on Azure Kubernetes Service
(AKS) with Workload Identity, eliminating the need to explicitly store
credentials in Kubernetes Secrets.

This change fixes Azure credentials validation to require a storage
account when using explicit credentials such as a storage key or SAS
token, and ensures the connection string is mutually exclusive with
other authentication parameters.

Follow-up to #700 to align the targetTime documentation with
cloudnative-pg standards. The note now covers all timestamp formats (not
just RFC 3339) and uses PostgreSQL format in the example to avoid
advertising the non-standard RFC3339-like format without timezone. A
warning has been added recommending to always specify an explicit
timezone to avoid ambiguity.

Update the machinery dependency to include the fix that ensures
RFC3339-like timestamps without timezone (e.g., "2024-01-15T10:30:00")
are interpreted as UTC.
The documentation has been updated to use a targetTime example with an
explicit Z suffix and to clarify that RFC3339-like timestamps without timezone
are interpreted as UTC.
