To enable +caching, set the "cachetextconv" variable in your diff driver's +config. For example: + +------------------------ +[diff "jpg"] + textconv = exif + cachetextconv = true +------------------------ + +This will cache the result of running "exif" on each blob +indefinitely. If you change the textconv config variable for a +diff driver, git will automatically invalidate the cache entries +and re-run the textconv filter. If you want to invalidate the +cache manually (e.g., because your version of "exif" was updated +and now produces better output), you can remove the cache +manually with `git update-ref -d refs/notes/textconv/jpg` (where +"jpg" is the name of the diff driver, as in the example above).
