* 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
* start banning malicious clients according to --ban-422
* reply with a blank 500 to stop firefox from retrying like 20 times
* allow Cc's in a few specific URL params (filenames, dirnames)
hitting enter would clear out an entire chain of modals,
because the event didn't get consumed like it should,
so let's make double sure that will be the case
connections from outside the specified list of IP prefixes are rejected
(docker-friendly alternative to -i 127.0.0.1)
also mkdir any missing folders when logging to file
add argument --hdr-au-usr which specifies a HTTP header to read
usernames from; entirely bypasses copyparty's password checks
for http/https clients (ftp/smb are unaffected)
users must exist in the copyparty config, passwords can be whatever
just the first step but already a bit useful on its own,
more to come in a few months
will probably fail when some devices (sup iphone) stream to car stereos
but at least passwords won't end up somewhere unexpected this way
(plus, the js no longer uses the jank url to request waveforms)
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
* some malicious requests are now answered with HTTP 422,
so that they count against --ban-422
* do not include request headers when replying to invalid requests,
in case there is a reverse-proxy inserting something interesting
* fix toast/tooltip colors on splashpage
* properly warn if --ah-cli or --ah-gen is used without --ah-alg
* support ^D during --ah-cli
* improve flavor texts
not even the deprecationwarning that got silently generated burning
20~30% of all CPU-time without actually displaying it anywhere, nice
python 3.12.0 is now only 5% slower than 3.11.6
also fixes some other, less-performance-fatal deprecations
never bonk anyone with read-access (able to see directory-listing)
or write-only (not able to retrieve any files at all) due to
either --ban-404 or --ban-url
fixes accidental ban when webdav-uploading files which
match any of the --ban-url patterns (#55)
also default-enables --ban-404 since it is now generally safe
(even when up2k is in turbo mode), plus make turbo smart enough to
disengage when necessary
accessing the syntax hilighter using a filekey is impossible anyways
because the client expects to build its state from the folder listing
and the backend refuses to return a listing given just a filekey
safari can immediately popstate when alt-tabbing back to the browser,
causing the page to load twice in parallel:
2174 log-capture ok
2295 h-repl $location
2498 h-pop $location <==
2551 sha-ok # from initial load
this carries some intentional side-effects; each thumbnail format will
now be stored in its own subfolder under .hist/th/ making cleanup more
effective (jpeg and webm are dropped separately)
table header click-handler didn't cover the entire cell so it was
easy to sort the table by accident; also do not exit hiding mode
automatically since you usually want to hide several columns
(so also adjust css to make it obvious you're in hiding mode)
* slightly faster startup / shutdown
* forgot a jinja2 golf
* waste 4KiB changing prismjs back to gz since brotli is https-gated ;_;
* broke support for firefox<52 (non-var functions must be toplevel
or immediately within another function), now even firefox 10 /
centos 6 is somewhat supported again
safest way to make copyparty like a general-purpose webserver where
index.html is returned as expected yet directory listing is entirely
disabled / unavailable
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
some of this looks shady af but appears to have been harmless
(decent amount of testing came out ok)
* some location normalization happened before unquoting; however vfs
handled this correctly so the outcome was just confusing messages
* some url parameters were double-decoded (unpost filter, move
destinations), causing some operations to fail unexpectedly
* invalid cache-control headers could be generated,
but not in a maliciously-beneficial way
(there are safeguards stripping newlines and control-characters)
also adds an exception-message cleanup step to strip away the
filesystem path that copyparty's python files are located at,
in case that could be interesting knowledge
* in case someone gets a confusing access-related error message,
include more context in serverlogs (exact path)
* fix js console spam in search results
* same markdown line-height in viewer and browser
good news: apple finally added support for samplerates other than
44100 for AudioContext, meaning it would now have been possible to
set non-100% volume for audio files including opus files
bad news: apple broke AudioContext in a way that makes it bug out
mediaSessions, causing lockscreen controls to become mostly useless
bad news: apple broke AudioContext additionally where it randomly
causes playback issues, blocking playback of audio files, even if
the AudioContext is sitting idle doing nothing (which is a
requirement for reliable upload speeds on other platforms)
disable AudioContext on iOS
by running dompurify after marked.parse if plugins are not enabled;
adds no protection against the more practical approach of just
putting a malicious <script> in an html file and uploading that,
but one footgun less is one less footgun
* --ban-url: URLs which 404 and also match --sus-urls (bot-scan)
* --ban-403: trying to access volumes that dont exist or require auth
* --ban-422: invalid POST messages, fuzzing and such
* --nonsus-urls: regex of 404s which shouldn't trigger --ban-404
in may situations it makes sense to handle this logic inside copyparty,
since stuff like cloudflare and running copyparty on another physical
box than the nginx frontend is on becomes fairly clunky
when repeatedly tapping the next-folder button, occasionally it will
reload the entire page instead of ajax'ing the directory contents.
Navigation happens by simulating a click in the directory sidebar,
so the incorrect behavior matches what would happen if the link to the
folder didn't have its onclick-handler attached, so should probably
double-check if there's some way for that to happen
Issue observed fairly easily in firefox on android, regardless if
copyparty is running locally or on a server in a different country.
Unable to reproduce with android-chrome or desktop-firefox
Could also be due to an addon (dark-reader, noscript, ublock-origin)
anyways, avoiding this by doing the navigation more explicitly
* 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
* --doctitle defines most titles, prefixed with "--name: " by default
* the file browser is only prefixed with the --name itself
* --nth ("no-title-hostname") removes it
* also removed by --nih ("no-info-hostname")
it was possible to set cookie values which contained newlines,
thus terminating the http header and bleeding into the body.
We now disallow control-characters in queries,
but still allow them in paths, as copyparty supports
filenames containing newlines and other mojibake.
The changes in `set_k304` are not necessary in fixing the vulnerability,
but makes the behavior more correct.
* always enable shift-click selection in list-view
* shift-clicking thumbnails opens in new window by default as expected
* enable shift-select in grid-view when multiselect is on
* invert select when the same shift-select is made repeatedly
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
* toastb padding fixes scrollbar on norwegian 403 in firefox
* fix text aspect ratio in seekbaron compact toggle
* crashpage had link overlaps on homepage
* error-message which explains how to run on py2 / older py3
when trying to run from source
* check compatibility between jinja2 and cpython on startup
* verify that webdeps are present on startup
* verify that webdeps are present when building sfx
* make-sfx.sh grabs the strip-hints dependency
* when accessing files inside an xdev volume, verify that the file
exists on the same device/filesystem as the volume root
* when accessing files inside an xvol volume, verify that the file
exists within any volume where the user has read access
* 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)
* winscp mkdir failed because the folder-not-found error got repeated
* rmdir fails after all files in the folder have poofed; that's OK
* add --ftp4 as a precaution
mainly motivated by u2cli's folder syncing in turbo mode
which would un-turbo on most dupes due to wrong lastmod
disabled by default for regular http listings
(to avoid confusion in most regular usecases),
enable per-request with urlparam lt
enabled by default for single-level webdav listings
(because rclone hits the same issue as u2cli),
can be disabled with arg --dav-rt or volflag davrt
impossible to enable for recursive webdav listings
