directory-tree sidebar did not sort correctly for non-ascii names
also fix a natural-sort bug; it only took effect for the
initial folder load, and not when changing the sort-order
also, natural-sort will now apply to all non-numeric fields,
not just the filename like before
* support newlines in svg files;
* `--error--\ncheck\nserver\nlog`
* `upload\nonly`
* thumbnails of files with lastmodified year 1601 would
make the cleaner print a harmless but annoying warning
the thumbnailer / audio transcoder could return misleading errors
if the operation fails due to insufficient filesystem permissions
try reading a few bytes from the file and bail early if it fails,
and detect/log unwritable output folders for thumbnails
also fixes http-response to only return svg-formatted errors
if the initial request expects a picture in response, not audio
remove an overly careful safety-check which would refuse creating
directories if the location was outside of the volume's base-path
it is safe to trust `rem` due to `vpath = undot(vpath)` and
a similar check being performed inside `vfs.get` as well,
so this served no purpose
the up2k databases are, by default, stored in a `.hist` subfolder
inside each volume, next to thumbnails and transcoded audio
add a new option for storing the databases in a separate location,
making it possible to tune the underlying filesystem for optimal
performance characteristics
the `--hist` global-option and `hist` volflag still behave like
before, but `--dbpath` and volflag `dbpath` will override the
histpath for the up2k-db and up2k-snap exclusivey
`--md-hist` / volflag `md_hist` specifies where to put old
versions of markdown files when edited using the web-ui;
* `s` = create `.hist` subfolder next to the markdown file
(the default, both previously and now)
* `v` = use the volume's hist-path, either according to
`--hist` or the `hist` volflag. NOTE: old versions
will not be retrievable through the web-ui
* `n` = nope / disabled; overwrite without backup
specifically google, but also some others, have started ignoring
rel="nofollow" while also understanding just enough javascript to
try viewing binary files as text
download-as-tar-gz becomes 2.4x faster in docker
segfaults on windows, so don't use it there
does not affect fedora or gentoo,
since zlib-ng is already system-default on those
also adds a global-option to write list of successful
binds to a textfile, for automation / smoketest purposes
too restrictive, blocking editing through webdav and ftp
but since logues and readmes can be used as helptext for users
with write-only access, it makes sense to block logue/readme
uploads from write-only users
users with write-only access can still upload any file as before,
but the filename prefix `_wo_` is added onto files named either
README.md | PREADME.md | .prologue.html | .epilogue.html
the new option `--wo-up-readme` restores previous behavior, and
will not add the filename-prefix for readmes/logues
just like before, if vpath contains ${u} then
the IdP-volume is created unconditionally
but this is new:
${u%+foo} creates the vol only if user is member of group foo
${u%-foo} creates the vol if user is NOT member of group foo
