Server aborted with "pure virtual method called" when the bind address
was in use: EiScreen's PortalInputCapture glib thread outlived Arch and
hit its freed vtable. ~EiScreen never deleted m_portalInputCapture, and
a fatal startup threw past cleanupServer(). Fix both.
Add util:CloseApplication entries for deskflow.exe, deskflow-core.exe,
deskflow-server.exe and deskflow-client.exe so Windows Installer's
Restart Manager can shut them down before file replacement. Without
this, in-place upgrades (especially pre-1.24 -> 1.24+, where the
old server/client binaries need removing) hit files-in-use and fall
back to prompting the user for a reboot.
Add libportal clipboard handling to the remote desktop.
Supports both directions (server to Wayland client paste,
and copy from the Wayland client back to the server)
for UTF-8 text, plain text, and PNG/BMP images.
The shared mime-type table, BMP/DIB and PNG encode/decode helpers, and
portal selection read/write live in a new PortalClipboard
helper used by both PortalInputCapture and PortalRemoteDesktop.
If the portal returns a restored RemoteDesktop session without clipboard
enabled (a token persisted before clipboard support existed), discard
the restore token and reconnect so the user gets a fresh permission
dialog. Otherwise the session would loop with a clipboard-less token
forever.
Send the clipboard over the libportal InputCapture portal. Only built
if the installed libportal has clipboard support.
AI disclosure: Claude was used on both sides of this work.
- Peter Hutterer: "The second commit was purely written by Claude
after I stared at this for too long without seeing any hope of
getting started. Turns out Claude wrote something that at least
looks correct and it does work. It needs review but also needs
knowledge of deskflow's internals that I don't have..."
- Nick Bolton: Claude also assisted with the follow-up work listed
below (image copy/paste, session re-request, race fixes, size/mime
validation, and CMake detection).
Server side (Wayland host, Peter Hutterer):
- Initial scaffolding for inputcapture clipboard support, guarded so it
only builds when the portal exposes the clipboard API.
- Integrate clipboard data into the inputcapture session so the host
clipboard can be offered to the remote (the Claude-written commit
referenced above).
Client side (Wayland receiver, KoljaFrahm):
- Receive clipboard data from the server and feed it into the local
clipboard through libportal. Built on the reference code by Peter:
https://github.com/whot/libportal-clipboard-test/tree/main
Build integration and rebase (Chris Rizzitello, sithlord48):
- Add the original CMake check for libportal/clipboard.h to define
HAVE_LIBPORTAL_CLIPBOARD, and guard the libportal clipboard use on
it.
- Update the code style and rebase onto the updated input capture
session persistence: https://github.com/deskflow/deskflow/pull/9415
Image support and reliability fixes (Nick Bolton):
- Support image copy/paste in addition to text, so screenshots and
other image clipboard contents work both ways through inputcapture.
- Re-request the input capture session when it comes up without a
clipboard, so new testers with existing sessions can get clipboard
functionality without needing to clear the session.
- Defer clipboard reads until the input capture session is active,
avoiding races where reads happen before the portal is ready.
- Fix assorted style issues in original commit to match conventions.
- Check the configured clipboard size limit and validate incoming
mime types before forwarding inputcapture clipboard data.
- Switch the CMake clipboard probe to check_symbol_exists so detection
matches what the compiler actually sees in the headers.
