when a file was reindexed (due to a change in size or last-modified
timestamp) the uploader-IP would get removed, but the upload timestamp
was ported over. This was intentional so there was probably a reason...
new behavior is to keep both uploader-IP and upload timestamp if the
file contents are unchanged (determined by comparing warks), and to
discard both uploader-IP and upload timestamp if that is not the case
due to all upload APIs invoking up2k.hash_file to index uploads,
the uploads could block during a rescan for a crazy long time
(past most gateway timeouts); now this is mostly fire-and-forget
"mostly" because this also adds a conditional slowdown to
help the hasher churn through if the queue gets too big
worst case, if the server is restarted before it catches up, this
would rely on filesystem reindexing to eventually index the files
after a restart or on a schedule, meaning uploader info would be
lost on shutdown, but this is usually fine anyways (and this was
also the case until now)
* make gen_tree 0.1% faster
* improve filekey warning message
* fix oversight in 0c50ea1757
* support `--xdev` on windows (the python docs mention that os.scandir
doesn't assign st_ino, st_dev and st_nlink on win but i can't read)
* permission `.` grants dotfile visibility if user has `r` too
* `-ed` will grant dotfiles to all `r` accounts (same as before)
* volflag `dots` likewise
also drops compatibility for pre-0.12.0 `-v` syntax
(`-v .::red` will no longer translate to `-v .::r,ed`)
when moving/deleting a file, all symlinked dupes are verified to ensure
this action does not break any symlinks, however it did this by checking
the realpath of each link. This was not good enough, since the deleted
file may be a part of a series of nested symlinks
this situation occurs because the deduper tries to keep relative
symlinks as close as possible, only traversing into parent/sibling
folders as required, which can lead to several levels of nested links
webdav clients tend to upload and then immediately delete
files to test for write-access and available disk space,
so don't crash and burn when that happens
* cpp_uptime is now a gauge
* cpp_bans is now cpp_active_bans (and also a gauge)
and other related fixes:
* stop emitting invalid cpp_disk_size/free for offline volumes
* support overriding the spec-mandatory mimetype with ?mime=foo
on upload, dupes are by default handled by symlinking to the existing
copy on disk, writing the uploader's local mtime into the symlink mtime,
which is also what gets indexed in the db
this worked as intended, however during an -e2dsa rescan on startup the
symlink destination timestamps would be used instead, causing a reindex
and the resulting loss of uploader metadata (ip, timestamp)
will now always use the symlink's mtime;
worst-case 1% slower startup (no dhash)
this change will cause a reindex of incorrectly indexed files, however
as this has already happened at least once due to the bug being fixed,
there will be no additional loss of metadata
* js: use .call instead of .bind when possible
* when running without e2d, the message on startup regarding
unfinished uploads didn't show the correct filesystem path
unposting could collide with most other database-related activities,
causing one or the other to fail.
luckily the unprotected query performed by the unpost API happens to be
very cheap, so also the most likely to fail, and would succeed upon a
manual reattempt from the UI.
even in the worst case scenario, there would be no unrecoverable damage
as the next rescan would auto-repair any resulting inconsistencies.
if someone with admin rights refreshes the homepage exactly as the
directory indexer decides to `_drop_caches`, the indexer thread would
die and the up2k instance would become inoperable...
luckily the probability of hitting this by chance is absolutely minimal,
and the worst case scenario is having to restart copyparty if this
happens immediately after startup; there is no risk of database damage
* when deleting files, do not cascade upwards through empty folders
* when moving folders, also move any empty folders inside
the only remaining action which autoremoves empty folders is
files getting deleted as they expire volume lifetimes
also prevents accidentally moving parent folders into subfolders
(even though that actually worked surprisingly well)
