Re-review 2 of #313: - n1: the cross-mount guard also matches when one path within its source ends with the other on a whole folder name (sources listed at different depths, e.g. 2024/x.png and x.png on a FUSE or noserverino mount). - n2: after a file's records move and right before its unlink, the held kept copy must still be the file at its path (fstat of the hold against os.stat) and the cross-mount guard must still hold; otherwise the file is kept, its records move back to it, and it counts as not removed.

"""Duplicate image files on the job registry (#249 System S6, Task 17).
|
|
|
|
- ``POST /prompt_manager/jobs/duplicates`` starts the find (202 ``{job}``):
|
|
kind ``duplicates``, "Find duplicate image files", admission ``read``,
|
|
cancellable, outcome group ``groups_found``. It hashes the media files of
|
|
every effective source (``_hash_media_groups``, shared with the legacy
|
|
scan) and the server keeps the groups it found under the job id: content
|
|
hash, root-relative paths and each file's source index. A find is refused
|
|
while a duplicate removal runs, and one find runs at a time.
|
|
- ``GET /prompt_manager/maintenance/duplicates/{job_id}?offset&limit`` pages
|
|
those groups, at most ``MAX_GROUP_PAGE`` at a time: ``{success, job:{id,
|
|
state}, total, offset, limit, groups:[{group_id, size, count, files}]}``.
|
|
Each file names its root-relative ``path``, its source's public label and
|
|
index and the Images serve URLs; never an absolute path.
|
|
- ``POST /prompt_manager/maintenance/preview {operation:"duplicate_files",
|
|
options:{job_id, keep:[{group_id, root_index, path}]}}`` reviews a removal:
|
|
in each group named, the files kept are the ones listed and every other
|
|
copy is removed. Each keeper and each removal is checked against the held
|
|
group, with containment decided as text before any filesystem access
|
|
(``file_problem``): inside its source, a media file outside
|
|
``thumbnails``, then a regular file (not a link) whose resolved path is
|
|
still inside the source, with the same size and content hash. A removal
|
|
that fails, or whose kept copy fails, is protected and listed with the
|
|
reason. The plan carries the files' database links, which move to the
|
|
kept copy.
|
|
- ``POST /prompt_manager/maintenance/apply {token}`` runs the reviewed plan
|
|
as the ``duplicate_cleanup`` job: admission ``records``, not cancellable,
|
|
groups ``removed``, ``kept`` and ``errors``. It checks the sources are
|
|
unchanged, takes the safety backup the policy promises (the database only;
|
|
removed files are not in it), then for each removal rechecks its kept copy
|
|
and the file itself (``file_problem``) and removes it with every handle
|
|
closed (``_unlink``), together with its thumbnail. A file that changed is
|
|
kept; the first unlink that fails stops the job, a locked file with the
|
|
coded ``LOCKED_FILE`` message (never the OS text), and the files after it
|
|
are not attempted. The database links of the files actually removed then
|
|
move to their kept copy (``PromptDatabase.move_file_links``).
|
|
|
|
The legacy gallery routes (``/scan_duplicates``, its stream and status, and
|
|
``/delete_duplicate_images``) keep their shapes on the same registry kinds;
|
|
see ``py/api/admin.py``.
