Sort proxy.* keys by dot depth, then name, before building the tree so
broader paths apply before deeper ones. When a new value would sit on a
node that is already a map, parse it as a YAML object (tabs normalized to
two spaces), deep-merge, and treat an empty string as an empty object.
Return clear errors when a scalar and a nested map disagree.
Drop the preallocated refPrefixes table in favor of refPrefix(n). Add
internal tests for parseLabelObject, mergeLabelMaps, key order, and
flatten; extend export tests for mixed OIDC-style labels and conflicts.
* refactor(docker): extract label parse and flatten helpers
Refactor ParseLabels by moving proxy label application into applyLabel,
descendLabelMap, and setLabelValue so traversal and leaf merge share one path
without labelLoop continues.
Add splitAliasLabel for ExpandWildcard so proxy.* prefix handling stays in one
place and uses CutPrefix/Cut consistently.
Deduplicate flattenMap and flattenMapAny value handling with flattenValue plus
joinLabelKey and stringifyLabelKey for flattened key construction.
* refactor(docker): structured errors for label type clashes
Replace ad hoc fmt.Errorf messages in descendLabelMap, setLabelValue, and
mergeLabelMaps with UnexpectedTypeError so wording is consistent and mapping
vs scalar conflicts stay explicit.
Hoist requireMap in label tests to a shared helper.
Normalize tabs to two spaces in expandYamlWildcard so wildcard YAML matches
the indentation used in the object-merge path.
* refactor(docker): optional UnexpectedTypeError message for merge conflicts
Extend UnexpectedTypeError with an optional Message field; when set, Error()
returns it instead of the default expect-versus-actual formatting.
mergeLabelMaps sets that message when a mapping would merge into an existing
scalar, so the error states the situation instead of only "expect scalar".
Update TestMergeLabelMaps to assert the new wording.
- Replace gperr.Error return types with standard error across test files
- Replace gperr.New with errors.New in validation and serialization tests
- Update API documentation in README files to use error instead of gperr.Error
- Simplify string parsing using strings.Cut in docker/label.go
- Update benchmarks to use NewTestEntrypoint and remove task package dependency
This is a large-scale refactoring across the codebase that replaces the custom
`gperr.Error` type with Go's standard `error` interface. The changes include:
- Replacing `gperr.Error` return types with `error` in function signatures
- Using `errors.New()` and `fmt.Errorf()` instead of `gperr.New()` and `gperr.Errorf()`
- Using `%w` format verb for error wrapping instead of `.With()` method
- Replacing `gperr.Subject()` calls with `gperr.PrependSubject()`
- Converting error logging from `gperr.Log*()` functions to zerolog's `.Err().Msg()` pattern
- Update NewLogger to handle multiline error message
- Updating `goutils` submodule to latest commit
This refactoring aligns with Go idioms and removes the dependency on
custom error handling abstractions in favor of standard library patterns.
- Added multiple test cases for the ExpandWildcard function to cover various scenarios including basic wildcards, no wildcards, empty labels, and YAML configurations.
- Improved handling of nested maps and invalid YAML inputs.
- Ensured that explicit labels and reference aliases are correctly processed and expanded.
- These changes makes the API incombatible with previous versions
- Added new types for error handling, success responses, and health checks.
- Updated health check logic to utilize the new types for better clarity and structure.
- Refactored existing handlers to improve response consistency and error handling.
- Updated Makefile to include a new target for generating API types from Swagger.
- Updated "new agent" API to respond an encrypted cert pair
