A CLIPRDR channel with a text-only backend (CF_UNICODETEXT): text copied
on the remote desktop is fetched and goes through the app's remote-
clipboard preference like VNC and OSC 52; local text is offered to the
remote when the desktop gains focus, on Ctrl+V and with Paste Clipboard
(which no longer types the text). Backend callbacks run inside the
active stage, so they queue requests that the session loop sends.
Verified against xrdp: the remote X clipboard read back the offered
text, and a remote copy arrived through on_clipboard.
Every modal read Enter/Escape globally, so a prompt that popped up over a
dialog, the palette, Quick Connect or an SFTP dialog could be answered
and the modal underneath confirmed or dismissed by the same key press.
All modals except the prompts now read those keys through
chrome::modal_key, which yields while a prompt is on screen.
- Protocol::Rdp with RdpConfig (domain, password mode, certificate
policy, TLS-only fallback, fixed or tab-sized resolution, SOCKS5/HTTP
proxy, SSH tunnel); migration 008 adds rdp_config and drops the
protocol CHECK constraint so new protocols no longer need a rebuild.
- Session manager: connect_rdp dials directly, via the shared proxy
module (proxy password from the secret store) or an SSH tunnel; the
server certificate goes through the known-hosts check (key type
rdp-tls); a tab-sized desktop uses the tab's reported pixel size, and
resizes wait until the server opens Display Control. Rejected NLA
passwords count as auth failures, so a saved one is asked again.
- The VNC viewer becomes DesktopView for both protocols; a small adapter
turns its keysyms and pointer masks into RDP scancodes, Unicode keys,
buttons and wheel events. For RDP, Paste Clipboard types the text.
- Profile editor RDP section, Quick Connect, badges, docs.
Verified against xrdp in the app: logon, desktop, input, and connections
through SOCKS5 and HTTP CONNECT relays. Not verified here: Windows/NLA
servers, the SSH tunnel route, and Display Control resizing (xrdp
0.9.24 never opened the channel).
Startup no longer looks for an AlchementaryLink data directory to copy
into NexusTerminal, and the 'Imported your Alchementary Link data' toast
and the migration docs are gone. Existing Alchementary Link installs are
no longer picked up automatically.
Session-only credentials (kept for a whole session so reconnects don't
re-prompt), credentials pending until a connection succeeds, and the
credential prompt's text buffer are now Zeroizing and wiped when
dropped, including when a prompt is cancelled or abandoned
(SEC-20261012-007, partial).
Still open: the values handed to the protocol clients are plain Strings
for the duration of authentication, egui keeps its own copies of typed
text, and no mlock/PR_SET_DUMPABLE is applied.
- Quick Connect runs the same validation as saved profiles, so an SSH
connection without a username fails up front with a clear message (F5).
- ~/.ssh/config imports fill a missing User (and jump-host user) with the
local user name, as ssh does, and skip blocks that still don't validate,
reporting how many (F6).
- An unrecognised hostKeyPolicy/lineEnding/parity/flowControl/direction in
a stored config falls back to that field's default instead of failing
the whole JSON column and silently resetting every other setting; parse
failures that remain are logged (F7).
Every shared lock was std::sync::Mutex with lock().unwrap() (~150 sites),
so a panic in any session's reader or callback poisoned the lock and the
next UI frame panicked too, dropping every open session. Locks are now
parking_lot::Mutex (no poisoning; already in the dependency tree), and a
panic hook reports worker panics as an error toast instead of the session
silently stopping (F3, F4).
A password typed at a 'saved' prompt was stored before the server
accepted it, so a typo was persisted and silently retried on every
reconnect. Typed values are now held per attempt and written once the
session connects; when the server refuses a saved credential the next
attempt asks again and the new value replaces it on success. A store
failure (keychain refused, vault locked) now shows a toast instead of
being swallowed, and reconnect prompts wait 5 minutes like the first
connect (SEC-20261012-015, F1, F2, F20).
OSC 52 and VNC ServerCutText now go through one handler that honours
'allow remote clipboard' and always toasts the first line, so a silent
clipboard swap can't set up a paste into another shell (SEC-20261012-010).
Multi-line pastes into a terminal without bracketed paste ask first, with a
preview (SEC-20261012-017). The launch-time update check can be turned off
and the updater docs no longer claim it is opt-in; the unused GitHub
fallback is removed (SEC-20261012-013, F15).
Under the 'ask' policy a changed host key used to be a hard error. The
prompt now shows the stored and received fingerprints and offers Reject,
Accept Once (connect, keep the record) and Accept & Update (replace the
record; audited). Unknown keys gain an Accept Once option too. Strict and
accept-new still refuse changed keys without prompting. Known-host rows
written by the old app are confirmed removable by id (test).
