Apsis 0.4.0

[0.4.0] - 2026-09-30

Apsis does four things: snapshot the system (with /root and /home as choices), a filter
list, delete snapshots, and (in 0.5.0) restore the whole system. The window is now laid out
like Timeshift's, in standard COSMIC widgets.

Upgrading

• Open the settings once and click Save. Settings from 0.3 (version 1 of
  /etc/apsis/config.toml) are shown converted: a home folder set to "everything" for every
  user becomes the /home choice, "hidden files only" becomes a + <home>/.** filter, and
  plain excludes get a -. The converted settings take the same files (checked with rsync in
  the tests). One exception: a + filter that a later filter used to hide now works, because
  the folders above a kept path are let in.
• Going back to 0.3: sudo cp /etc/apsis/config.toml.bak /etc/apsis/config.toml (0.3 can't read
  version 2).
• File restore is gone. Anything in ~/Apsis-restored/, and any *.apsis-before-* file next to
  an original, is yours; delete it by hand when you don't need it.
• The helper's D-Bus interface is now io.github.atraxsrc.Apsis.Helper2. After upgrading, log
  out and in (or re-add the applet) so the panel runs the new version.

Added

• A window like Timeshift's: a toolbar (Create, Delete, Settings), the snapshot list (date and
  comment; Ctrl-click and Shift-click select several), and a status area with the last
  snapshot, the backup disk and its bar, and a running snapshot's progress.
• Settings as tabs: Location (the backup disk), Include (/root, on by default; /home,
  off by default), Filters (+/- list with Add Folder, Add File, Add Pattern, Remove,
  Move Up, Move Down; new lines go on top), Misc (reminder, panel label).
• Stop a snapshot while it's being made: rsync's process group is ended and what it copied
  removed. The user who started it isn't asked for a password (new polkit action stop for
  anyone else).
• Every window and the panel popup show a snapshot being made or deleted elsewhere, and list
  again when it ends.
• What an interrupted snapshot leaves behind is shown in the list, removed by the next
  snapshot, and can be deleted.
• A backup disk pulled out during a snapshot or delete is reported as such by the helper.
• Keyboard shortcuts: Ctrl+N, Delete, Ctrl+R / F5, Ctrl+,, Ctrl+A, arrows, Esc (man page and
  README).

Changed

• No terminal look: no prompt line, no key-hint footer, no rooms or dock.
• The panel popup uses standard widgets: last snapshot, backup disk, a running job, the newest
  snapshots, Open Apsis and Refresh.
• A failed create's staging folder is removed with the delete's safe walk.
• rsync gets --delete-excluded once (Timeshift passes it twice).
• Summary: "System snapshot and restore".

Removed

• Restoring single files (the browser, both restore modes, Apsis-restored, .apsis-before
  backups) and the polkit actions browse, restore and restore-original.
• Keep last N snapshots, and its preview.
• Per-user home folder modes (excluded / hidden files only / everything).
