Audit fixes for the daemon:
- Decode gif/webp/bmp/tiff/ico (enable the pure-Rust image features). These
mimes were accepted by pick_mime but the image crate only had png/jpeg, so
thumbnail decode failed and the item was silently dropped. Drop avif (needs
heavy C deps) and svg (not a raster format the image crate decodes) from the
allowlist so unsupported types are never selected.
- ItemAdded signal preview now uses db::PREVIEW_CHARS (200), matching the
history/search queries, so a just-copied row and the same row after a reload
carry identical text.
- Add a deterministic ", rowid DESC" tiebreaker to the three created_at DESC
orderings (history, search, prune) so items sharing a millisecond have a
stable order and prune can't evict the wrong one at the boundary.
- SetConfig now prunes immediately (and emits ItemDeleted) when max_history is
lowered, instead of waiting for the next copy.
- Request the bus name with AllowReplacement (plus ReplaceExisting) so a
reload's new instance can cleanly take the name; fix the misleading comment.
- Wayland monitor clears its pending-offers map on Selection{None} so it can't
grow across copy-then-clear cycles (wlroots path).
- Document that SubmitItem is a trusted-caller method (the password-manager
hint is enforced client-side; forwarding it is a future contract change).

Strata
A fast, stutter-free clipboard manager for GNOME Shell.
All heavy work (hashing, decoding, storage, search, thumbnails) lives in a Rust daemon. The GNOME Shell extension only renders UI and forwards events over D-Bus, so the compositor is never blocked, even with thousands of items.
Architecture
Strata is two components, and you need both for it to work:
| Component | Language | Role |
|---|---|---|
strata-daemon/ |
Rust + tokio + zbus | Storage (SQLite + FTS5), dedup, thumbnails, D-Bus service org.gnome.Strata |
strata@edu4rdshl.dev/ |
GJS (GNOME Shell extension) | Top-bar panel, search UI, paste-back, clipboard ingest |
The extension auto-connects to the daemon on enable. If the daemon is managed
by systemd (or another init system), the extension detects it and skips
spawning its own copy. If no daemon is running, the extension looks for
strata-daemon in $PATH and spawns it directly.
GNOME Shell (GJS) ──D-Bus──▶ strata-daemon ──▶ SQLite (~/.local/share/strata)
│
└──▶ thumbnails (~/.cache/strata)
Requirements
- GNOME Shell 50 (tested). May work on 45–49 but untested — if you try it and it works, please open an issue to let us know.
strata-daemonbinary in$PATH(see Install below)- Rust 1.74+ (build only)
glib-compile-schemas(fromglib2-devel/libglib2.0-dev-bin)- SQLite is bundled via
rusqlite, no system dep needed
Install
From source (local build)
git clone https://github.com/Edu4rdSHL/Strata.git
cd Strata
# Build and install the daemon binary to ~/.local/bin
make install-daemon
# Install the GNOME Shell extension
make install
Make sure ~/.local/bin is in your $PATH, then log out / log back in
(Wayland) or Alt+F2 → r (X11) and enable:
gnome-extensions enable strata@edu4rdshl.dev
Via systemd user service (distro packages / manual)
Distro packages install the daemon binary to /usr/bin/strata-daemon and
the systemd unit from contrib/systemd/strata-daemon.service to
/usr/lib/systemd/user/. Enable it once:
systemctl --user enable --now strata-daemon
Then install and enable the extension as above. The extension detects the running daemon and will not spawn a second copy.
Pack for extensions.gnome.org
make pack # produces strata@edu4rdshl.dev.shell-extension.zip (JS only)
Uninstall
gnome-extensions disable strata@edu4rdshl.dev
rm -rf ~/.local/share/gnome-shell/extensions/strata@edu4rdshl.dev
rm -rf ~/.local/share/strata ~/.cache/strata # also wipes history
Other desktops?
The daemon is desktop-agnostic. It speaks plain D-Bus and runs anywhere
the session bus does. Any client (KDE applet, CLI tool, your own script)
can drive it. See strata-daemon/README.md for
the wire protocol and a busctl example.
The shipped UI is a GNOME Shell extension. Ports to other desktops only need a new front-end against the same D-Bus interface.
