- St Spec
- -- ----
- OK If -f is requested, ensure -e is too.
- Check if volumes is using AFPVOL_CACHE, then wipe db from disk. Rebuild from ad-files.
-
- 1st pass: Scan volume
- --------------------
-
- St Type Check
- -- ---- -----
- OK F/D Make sure ad file exists
- OK D Make sure .AppleDouble dir exist, create if missing. Error creating
- it is fatal as that shouldn't happen as root.
- OK F/D Delete orphaned ad-files, log dirs in ad-dir
- OK F/D Check name encoding by roundtripping, log on error
- OK F/D try: read CNID from ad file (if cnid caching is on)
- try: fetch CNID from database
- -> on mismatch: use CNID from file, update database (deleting both found CNIDs first)
- -> if no CNID in ad file: write CNID from database to ad file
- -> if no CNID in database: add CNID from ad file to database
- -> on no CNID at all: create one and store in both places
- OK F/D Add found CNID, DID, filename, dev/inode, stamp to rebuild database
- OK F/D Check/update stamp (implicitly done while checking CNIDs)
-
-
- 2nd pass: Delete unused CNIDs
- -----------------------------
-
- St Spec
- -- ----
- OK Step through dbd (the one on disk) and rebuild-db from pass 1 and delete any CNID from
- dbd not in rebuild db. This in only done in exclusive mode.
