Shows the errata from the ESGF errata service that affect the datasets in a recipe, on the line of the dataset, linked to the erratum. Errata are shown as information, to distinguish them from errors and warnings about the recipe itself, and the message gives their status (new, on hold, resolved, or won't fix). Resolved errata are only shown if the recipe pins an affected version, because a resolved erratum usually no longer affects the latest version. If an erratum only affects some of the variables of a dataset, the message names them.

The errata are looked up in the background after the problems in the recipe have been shown, shown as they are found, and the answers of the service are kept on disk for a day with requests-cache. The service is searched by project, model, and experiment, and the affected datasets are matched in the server. The errata service API is not documented, so this may need to change if the service changes. The setting esmvaltool.languageServer.errata (or initializationOptions.errata in other editors) turns this off.

Files that are not ESMValTool recipes get no errata. tests/test_links.py checks that the erratum page the diagnostics link to resolves.

Tested with pixi run test, pixi run pre-commit run --all-files, and against the real service with recipes with CESM2 and GFDL-CM4 datasets.
