* feat(instrumentation): add OTel exception semantic convention log handler
Add a loghandler.Wrapper that enriches error log records with OpenTelemetry
exception semantic convention attributes (exception.type, exception.code,
exception.message, exception.stacktrace).
- Add errors.Attr() helper for standardized error logging under "exception" key
- Add exception log handler that replaces raw error attrs with structured group
- Wire exception handler into the instrumentation SDK logger chain
- Remove LogValue() from errors.base as the handler now owns structuring
* refactor: replace "error", err with errors.Attr(err) across codebase
Migrate all slog error logging from ad-hoc "error", err key-value pairs
to the standardized errors.Attr(err) helper, enabling the exception log
handler to enrich these logs with OTel semantic convention attributes.
* refactor: enforce attr-only slog style across codebase
Change sloglint from kv-only to attr-only, requiring all slog calls to
use typed attributes (slog.String, slog.Any, etc.) instead of key-value
pairs. Convert all existing kv-style slog calls in non-excluded paths.
* refactor: tighten slog.Any to specific types and standardize error attrs
- Replace slog.Any with slog.String for string values (action, key, where_clause)
- Replace slog.Any with slog.Uint64 for uint64 values (start, end, step, etc.)
- Replace slog.Any("err", err) with errors.Attr(err) in dispatcher and segment analytics
- Replace slog.Any("error", ctx.Err()) with errors.Attr in factory registry
* fix(instrumentation): use Unwrapb message for exception.message
Use the explicit error message (m) from Unwrapb instead of
foundErr.Error(), which resolves to the inner cause's message
for wrapped errors.
* feat(errors): capture stacktrace at error creation time
Store program counters ([]uintptr) in base errors at creation time
using runtime.Callers, inspired by thanos-io/thanos/pkg/errors. The
exception log handler reads the stacktrace from the error instead of
capturing at log time, showing where the error originated.
* fix(instrumentation): apply default log wrappers uniformly in NewLogger
Move correlation, filtering, and exception wrappers into NewLogger so
all call sites (including CLI loggers in cmd/) get them automatically.
* refactor(instrumentation): remove variadic wrappers from NewLogger
NewLogger no longer accepts arbitrary wrappers. The core wrappers
(correlation, filtering, exception) are hardcoded, preventing callers
from accidentally duplicating behavior.
* refactor: migrate remaining "error", <var> to errors.Attr across legacy paths
Replace all remaining "error", <variable> key-value pairs with
errors.Attr(<variable>) in pkg/query-service/ and ee/query-service/
paths that were missed in the initial migration due to non-standard
variable names (res.Err, filterErr, apiErrorObj.Err, etc).
* refactor(instrumentation): use flat exception.* keys instead of nested group
Use flat keys (exception.type, exception.code, exception.message,
exception.stacktrace) instead of a nested slog.Group in the exception
log handler.
