This is mainly for linux, whose local is not UTF-8.
For example, in latin1, it is not possible to encode emoji or chinese character.
If there are such character in the filename, Qt would just save the file using
the replacement character ('?'). Then, on the next sync, client would rename
the files using this replacement character.
Avoid this by ignoring the files which cannot be downloaded because the
filename cannot be represented with the user's locale
Relates to issue #5676 and #5719
* Drop AvatarJob2
* Allow AvatarJob to retrieve different sizes and users
* Make creating a circular avatar into a function
(maybe all avatars should be made into that shape in the first place)
[Sharing] Show placeholders for avatars
Just like on the web show placeholders for avatars in the sharing dialog
[Sharing] Show avatars!
[Sharing] Show same avatar placeholder for group/federated shares as on
web
To do this conveniently a bunch of functionality that's common to
IssueWidget and ProtocolWidget is moved to ProtocolItem.
Also the convenience function to asynchronously retrieve the private
link url is moved from the socket api to the network jobs.
The menu can be open with the keyboard shortcut.
(Fixup for the fix of #5596)
Also use popup instead of exec to show the menu: it's safer as it does
not re-enter the event loop.
Previously we required matching mtimes but that's actually
unnecessary when the question is about whether to skip the
download. We will still update the file's metadata.
Also, adjust behavior when the checksum is weak (Adler32):
in these cases we still depend on equal mtimes.
Some servers have non-compliant instance ids (that start with a number)
and thereby make deducing the numeric file id from the full id
unreliable.
To circumvent this problem we retrieve the fileid property from the
server with a PROPFIND.
This restores 2.3 behavior. Some servers reply 404 to GETs and PROPFINDs
to the remote.php/webdav/ url and used to work. Being more picky would
break them.
The assert was made fatal when looking at asserts for #5429#5518
without having a particular problem in mind. Recent reports weakly
suggest that this might lead to occasional crashes for users when
sqlite_close fails in ways that look ignorable.
