- Add org-id resolution for [[id:...]] links by building ID locations database once before parallel export - Handle broken file links gracefully with org-export-with-broken-links - Fix race condition in parallel exports by pre-building ID cache - Fix Quartz config not being applied: cp was preserving nix store hash prefix in filename instead of using explicit destination filename - Continue pipeline even when some exports fail, reporting failures - Improve error handling and logging throughout export pipeline

Telemetry event definitions and logging handler.
|
|
|
|
## Events
|
|
|
|
The following telemetry events are emitted:
|
|
|
|
* `[:org_garden, :export, :start]` — Export of a single file started
|
|
- Metadata: `%{file: path}`
|
|
|
|
* `[:org_garden, :export, :stop]` — Export of a single file completed
|
|
- Measurements: `%{duration: native_time}`
|
|
- Metadata: `%{file: path}`
|
|
|
|
* `[:org_garden, :export, :exception]` — Export failed
|
|
- Measurements: `%{duration: native_time}`
|
|
- Metadata: `%{file: path, kind: kind, reason: reason}`
|
|
|
|
* `[:org_garden, :watcher, :file_processed]` — File change processed
|
|
- Metadata: `%{path: path, event: :created | :modified | :deleted}`
|
|
|
|
* `[:org_garden, :server, :start]` — Server started
|
|
- Metadata: `%{port: port}`
|
|
|
|
* `[:org_garden, :server, :stop]` — Server stopped
|
|
- Metadata: `%{reason: reason}`
|
|
|
|
## Usage
|
|
|
|
Attach a handler to log events:
|
|
|
|
OrgGarden.Telemetry.attach_logger()
|
|
|
|
Or use `:telemetry.attach/4` for custom handling.
