i looked into this.
/sys/src/cmd/fossil/cache.c:1210,1217
if(p->index < 0){
/*
* We don't know how to temporarily undo
* b's dependency on bb, so just don't write b yet.
*/
if(0) fprint(2, "blockWrite skipping %d %x %d %d; need
to write %d %x %d\n",
b->part, b->addr, b->vers, b->l.type, p->part,
p->addr, bb->vers);
return 0;
}
what if bb == b?
it'd be interesting to see what that outputs with if(1).
i think _cacheLocalLookup is finding the superblock
itself. perhaps no write between snaps meaning that
only the sb itself is dirty?
