◆ CRAWL_BIT_A

#define CRAWL_BIT_A (1 << 4)

Why anything writing main.images.flags behind the image cache has to keep the cache in step.

A cache entry holds its own dt_image_t, and releasing it writes that WHOLE struct back – which is how a rating reaches the database (metadata/ratings.c). So a row updated straight through the repository while a stale entry sits in the cache is not durable: the next release of that entry overwrites it, at a moment nothing connects to the update.

The XMP crawler is the caller this was found on (control/crawler.c). It takes the entry and edits it when there is one, and writes the row only when there is not; these tests pin both halves of that reasoning – the hazard, and the sequence that avoids it.
