Adds a sidecar TDB written by each per-port-pair child whenever a connection appears or changes. The udpproxy parent recreates the file at startup and clears records for exiting / removed entries. Web admin and CLI tools read this to render who is currently connected. Snapshot is throttled (10s) and forked into a grandchild, mirroring the save_signing_timestamp pattern in mavlink.cpp so main_loop never blocks on disk I/O. New connections reset the throttle to 0 so the record appears on the next loop iteration without waiting a full tick. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Parses ConnEntry records using the same forward-compatible scheme as keydb_lib (>= MIN_SIZE accepted, trailing bytes preserved on read). Exposes iter_active() / list_active() with a 30s stale-record filter as defence in depth against orphans the parent failed to clean up. Used by webadmin/connections.py and the keydb.py stats command.

New /admin/connections route lists every active connection across all entries (peer, transport, uptime, rx/tx). The owner /me/ page gains a per-entry section showing only that owner's own connections. Both pages auto-refresh every 10s via a meta refresh in the new head_extra block.

Loads the running build's hash from a git-version.txt file written into the repo by scripts/update_server.sh before rsync (.git/ itself is excluded from rsync, so reading the live hash on the server isn't viable). Falls back to live git rev-parse for local dev. The GitHub repo URL defaults to ArduPilot/UDPProxy and is overridable via webui.json's "github_repo" field.

Reads connections.tdb (sibling of keys.tdb) via conntdb_lib and prints one line per active connection, joined with the entry's name from keys.tdb. Convenient for quick on-server checks without loading the web UI. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two related deploy fixes: - Capture the local 'git rev-parse --short HEAD' into git-version.txt before rsync so the deployed web UI can show the running commit in its footer (the .git directory itself is excluded from rsync). - pkill the webadmin gunicorn alongside udpproxy. start_proxy.sh skips relaunching gunicorn if one's already up, so without this step the new code is rsynced but the old worker keeps serving.

keydb.py imports conntdb_lib at startup (for the new 'stats' command), so the runtime stage of docker/Dockerfile needs the file alongside keydb.py / keydb_lib.py. Without this the 'docker-test' CI job fails with ModuleNotFoundError on any keydb.py invocation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
