/* Move existing photos out of the database and onto disk.
|
|
*
|
|
* node scripts/photos-to-disk.cjs # report only
|
|
* node scripts/photos-to-disk.cjs --write # actually move them
|
|
*
|
|
* Safe to run repeatedly: it only touches rows that still have base64 in `data` and no `path`,
|
|
* and it clears `data` only after the file is on disk and has been read back and verified byte
|
|
* for byte. A crash halfway leaves rows that are readable from either place, which is why the
|
|
* serving route handles both.
