A cursor id was the platform's handle for the shape: HCURSOR on Windows, the XFixes serial on X11. Apps mint a new handle for a shape they have shown before (Chrome, Electron, Qt custom cursors), and an X11 animated cursor gets one per frame, so one arrow arrived under thousands of ids over a session. The controlled side cached and sent it again under each, and the controller decoded, rendered and kept it again under each, and grew by gigabytes over weeks of connection. The controlled side now names a shape by an xxh3 hash of its size, hotspot and pixels, taken once when a handle is first seen, before the pixels are compressed. The per-connection send already sends a shape once and afterwards only its id, so a shape now crosses once however many handles it has. The id is opaque in the protocol, so controllers of any version accept it. The DRM backend already named shapes by content with FNV-1a; it uses the same hash now. A peer before 1.5.0 still names shapes by handle, and the fix has to work against every deployed peer. For those peers the controller hashes each CursorData's compressed colors with its geometry: one peer compresses the same pixels to the same bytes, so a shape seen before is recognised without being decompressed. The UI gets that shape once, under one id, and every later handle for it is passed on as a cursor_id of that id. The map from the peer's ids is kept for the connection, unbounded, since the peer sends a shape once and may select any id it named again; an entry is two integers. From 1.5.0 the controller passes the peer's ids through unchanged, on the old path. The web core in flutter/web does the same in its own tree.

# One branch off upstream v0.13.0, the tag whose crate versions match this stack.

# webrtc-util: reads the Windows adapter list's IPv6 addresses as host-order u16 groups, so every
|
|
# one comes out byte-swapped, fails to bind, and ICE gathers no IPv6 host candidate on Windows;
|
|
# and names every Windows adapter "" with no mask, so ICE cannot tell one adapter's addresses
|
|
# from another's; and lays the adapter struct out in nested parts, whose padding on x64 shifts
|
|
# every field after OperStatus, Ipv6IfIndex first.
|
|
# webrtc-ice: best effort, one IPv6 host candidate per interface and prefix - the one the OS
|
|
# sends from when that is one of the group's, else all of them - since the stable address beside
|
|
# the temporary one is an identifier that outlives every rotation and that nothing else this
|
|
# machine sends out ever shows.
|
|
# webrtc-sctp: RFC 4960's 1s RTO floor makes a single loss cost 1-3s on a link whose RTT is 24-64ms,
|
|
# and fast retransmit cannot cover a request/response exchange; INITIAL_MTU 1228 also fragments on
|
|
# IPv6; and its AIMD pins a lossy long-haul link to MSS/(RTT*sqrt(p)), so a switch sends without
|
|
# a congestion window, as KCP does - on by default, `allow-webrtc-congestion-control` opts back in.
|
|
# Sending that way, a reordering window keeps a chunk that is merely late from being resent on a
|
|
# path that jitters, every DATA chunk asks for its SACK at once so a lost tail is back within an
|
|
# RTT at KCP's RTO floors, and bundles of small chunks stay within the MTU. A T3-rtx resends
|
|
# everything outstanding when it packs into four packets and otherwise probes with one and lets
|
|
# the SACK settle the rest (F-RTO), timed from the latest send, so a stall no longer resends the
|
|
# whole backlog behind itself while a short lost tail still comes back at once. A DATA chunk
|
|
# received again is listed in the SACK, which never happened - the sender widens its reordering
|
|
# window on that - and the SACK keeps to the MTU too, the lowest gap blocks first.

# Pinned by rev, not branch: a fork branch can be rewritten out from under the lockfile.
