Clear the 5-second SO_RCVTIMEO that was set during the connection
handshake but never removed. The timeout persisted into the game
session, causing the client to disconnect whenever the server paused
for longer than 5 seconds (e.g. autosave, chunk I/O).
Also update README with chunk unloading and connection stability fixes.
Commit a24318ee changed drop() to immediately remove chunks from cache,
bypassing the deferred m_toDrop save/unload pipeline. This caused missing
chunks on dedicated servers, iterator invalidation in dropAll() and
ServerLevel::save(), and entity duplication (item frames) from chunks
being reloaded without their entities first being removed from the level.
- ServerChunkCache::drop(): restore m_toDrop queue instead of immediate
cache removal, so tick() can save/unload/move to unloadedCache safely
- MultiPlayerChunkCache::drop(): restore soft-unload (keep chunk in cache
with loaded=true) instead of nulling cache and hasData
- PlayerChunkMap::setRadius(): remove dropAll() call when reducing radius,
the per-chunk removal loop already handles out-of-range chunks
The dedicated server previously picked a completely random seed with no
biome diversity checks (the client validates but the server skipped it).
On top of that, the client's findSeed() was hardcoded to only check a
54-chunk (Classic) area, so Large worlds had no diversity guarantee
beyond the center.
New server worlds now use findSeed() scaled to the full target world
size. Added override-seed in server.properties to fix existing worlds
without deleting them.
Server list: edits and deletions now update the UI immediately by
calling SearchForGames() in ForceFriendsSessionRefresh() and
UpdateGamesList() on nav-back to LoadOrJoinMenu.
Connection: moved WinsockNetLayer::JoinGame() to a background thread
with non-blocking sockets (5s timeout, 3 retries). Users can cancel
with B/Escape during the attempt. Failed connections always show an
error dialog.
The upstream font color fix (commit be7e2ca9) switched from glColor4f to
per-vertex t->color() but renderUnicodeCharacter() still relied on glColor4f.
Set glColor4f to currentColor before rendering unicode glyphs and restore
white after, and re-apply t->color() when resuming the batched draw.
Cherry-picked upstream sign fix (SignEntryMenu720 restored) and re-applied
VSync and ExclusiveFullscreen checkbox patches to all SettingsGraphicsMenu SWFs
using the ffdec_lib Java tools.
