nvrl 14a663cee9 fix(fuse): keep pinned files on disk through remote changes
A remote change to a pinned file called `ContentCache::evict`, which does
not check pins, and only the pin request itself ever downloaded anything.
An edit from another device, or even a rename, left the file listed as kept
offline with no copy, so the next read downloaded it or failed without a
network. A file added to a pinned folder elsewhere was never downloaded,
and a folder pin whose downloads failed while offline never retried them.

A remote change no longer evicts a pinned file's copy. The copy is checked
against the revision's (mtime, size), so a newer revision does not read
it, and a rename keeps the mtime (B123), so the copy stays valid. A new
pdfs-pin-keeper thread checks pins again and downloads files that are
missing or stale:

- the pins a batch of remote events changed, after the batch's listings
  are dropped, including a pinned folder that gets a new file;
- every pin at startup, when the link returns, and after the event feed
  loses continuity;
- a file whose version is restored.

Failed downloads retry with a backoff of 30 s to 30 min. Pinning and the
keeper settle a provisional size first: a copy stored under the
ciphertext size never matched the plaintext it holds.

Fixes B282.

Proton Drive for Linux documentation

Proton Drive for Linux is an unofficial Proton Drive client for the Linux desktop. Your Drive appears as a folder that downloads files when you open them, local folders are backed up and kept in sync, and a GTK app with a tray icon and a search launcher covers Photos, sharing and more. A command-line client does all of it from a terminal.

These pages are also published as the wiki, generated from the docs/ folder of the repository.

Where to start

  • New here? Getting started takes you from installing to your first synced folder.
  • Installing or updating? Installation covers Fedora (COPR), Arch (AUR), Debian and Ubuntu, NixOS, and building from source.
  • Something not working? Troubleshooting starts with pdfs diagnose and goes through common problems.
  • New computer, or the old one is gone? Recovering on a new computer gets your synced folders back.
  • Quick question? Try the FAQ.
