Off the network the datagram reaches nobody and the send succeeds, but
the session was recovered first, and a send whose session wasn't up
returned WOULD_BLOCK (pspautotests net/adhoc/pair/vanish, PDP send after

Each instance paced itself against the wall clock, so on a busy machine
the one that got less CPU fell behind, and anything a test times across
instances (a peer leaving, a matching timeout) came out differently with
the load: pair/vanish and pair/matching3 failed on macOS CI.
With --sync-file and --sync-count, instances on one machine share a file
of one slot per instance. CoreTiming ends a slice at every emulated
millisecond, publishes it there, and waits until every other instance
has reached it too, so they're never more than a millisecond apart. It
works for any number of instances. One that stops moving (a debugger
pause, a crash) is waited for 2 s and then left out until it moves
again, and one that blocks the CPU thread in real time on something the
others must do (the relay PTP connect) stands aside meanwhile.
Tools/adhoc_multi.py and adhoc_session.py use it (--no-sync turns it
off). The host's 1 s head start is gone: they wait for the server's
port instead. adhoc_multi writes each instance's output to a file, as a
full pipe would now stop the other instances too.

The server loop polled every socket and slept 10 ms, so it woke 100
times a second with nothing to do, and every message could wait up to
10 ms of real time before it was handled, which at a sped-up emulation
speed is many times that in game time. It now waits in select() on the
listening socket and every user, and wakes at least every 50 ms to notice
being stopped. It also no longer stops serving everyone while the hosting
instance is paused in the debugger.

A PSP keeps what arrives in the socket's buffer, of the size given to
PdpCreate, and drops a datagram that doesn't fit: a buffer of 0 gets
nothing, one of 2048 bytes only some of ten 1000-byte datagrams
(pspautotests net/adhoc/pair/flow). Each transport now only hands over
the datagrams that have arrived (PdpTakeDatagram), into a queue per
socket that is filled every millisecond and whenever the game looks, and
PdpRecv, its blocking retry, GetPdpStat, PollSocket and game mode read
from that. This replaces each transport's own receive paths, so the
relay now reports the sender with NOT_ENOUGH_SPACE too, and P2P's
blocking receive no longer misreads a stale errno.
A datagram to ourselves goes straight into our own socket's queue, as on
a PSP, so it's there at once through the relay too (net/adhoc/term).
Also from comparing the transports:
- P2P: a blocking Accept of a connection from outside the group keeps
waiting instead of returning -1.
- Relay: an accepted socket gets an id of its own, not its listener's,
which blocking calls are told apart by.
- ALERT in PollSocket comes from the socket in both transports.
- No send/receive timeouts are set on the game's sockets: all host
sockets are non-blocking, and in relay mode the ids aren't host
sockets at all.

Winsock never makes a socket whose connect failed writable; the failure
shows in select's exception set, with the reason in SO_ERROR. The poll
now checks both, and SO_ERROR on a writable socket too, which is where
other systems put a refusal.
Windows still retries a refused connect for about a second before
reporting it, far longer than a PSP at the tests' 800% speed, so
pair/basic is a known P2P failure on Windows.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- A connect PtpOpen started counted as up as soon as getpeername
succeeded, which on Windows happens while it's still in progress, even
one about to be refused. It now needs the socket ready too, and a
pending connect's failure is read from SO_ERROR, the only place Windows
reports it (pspautotests net/adhoc/pair/basic).
- Out of the group, PdpRecv only dropped what its peek saw; on Windows a
peek can fail and leave the next datagram unchecked, so a vanished
client still got the host's data (pair/vanish).
pspautotests: pair/vanish times PTP's failure from when the peer left the
peer list.

The connect PtpOpen starts goes through the relay on a host thread, so
when it finished in emulated time depended on the emulation speed and on
how busy the host was. At --speed=800 on a loaded CI runner it often
wasn't up within the 100 ms net/adhoc/pair/ptppoll polls for, while on a
PSP it's up a few ms after PtpOpen.
The relay's per-millisecond poll now waits (at most a second, once per
connect) for a connect in progress to finish, filling local listeners'
backlogs meanwhile, since the listener may be on the same console.

- GetPtpStat on a listener read its listen session as a connection,
which could write past it; a listener now reports nothing waiting.
Neither GetPtpStat nor GetPdpStat reports a dead session's negative
status as a byte count any more, and a new PDP socket starts with
nothing waiting instead of its buffer size.
- A poll of a connection whose peer has closed reports DISCONNECT, as
the P2P transport and a PSP do (pspautotests net/adhoc/poll).
- Only a send that went out counts as the last send for a vanished
peer's timeout.

A connect to a port nobody listens on is refused within a second on a
PSP, and every later connect on that socket is refused too, even once
something listens there (pspautotests net/adhoc/pair/basic,
pair/ptpclose). PPSSPP recreated the socket and tried again until the
game's timeout ran out, to cover a peer that wasn't listening yet.
Dissidia 012 and Fate/Unlimited Codes, named in the old comments, still
get to their matches.
Also set the established time wherever a connection becomes established,
which the timing of a vanished peer's failure counts from.

How long an adhocctl request waits for the server before giving up, and
how long a joiner's GAME event waits for the host to show up, were

longer when slowed down.

A PSP completes a connect to a listener without the game calling Accept,
so an opened PTP connection is up a few ms after PtpOpen (pspautotests
net/adhoc/pair/ptppoll). The relay only answers the connecting side once
the listening side accepts, so the relay transport now accepts pending
connections into a queue as long as the listener's backlog, from a new
per-millisecond AdhocTransport::Poll() and from polls and accepts, and
PtpAccept takes them from there. A poll reports ACCEPT while the queue
isn't empty.

Out of the group, a PSP's sends reach nobody and nothing reaches it, and
a PTP connection to a peer that has left fails once its retransmits would
have run out. Only the relay transport did this; the P2P one kept sending
over the host's sockets, so neither side ever noticed the other was gone
(pspautotests net/adhoc/pair/vanish).

Each started context had two host threads, polling every 10 ms of wall
time: one sent queued packets, received, and ran hellos, keepalives and
timeouts, and the other handed events to the callbacks. A single
CoreTiming event now does both for every running context, every 1 ms of
emulated time, and Stop does what the threads did on their way out.
Matching no longer depends on host scheduling or wall-clock delays, so an
accept's ESTABLISHED comes 1-10 ms after SelectTarget at any emulation
speed, as on a PSP (pspautotests net/adhoc/pair/matchingaccept).

Polling an unconnected or listening PTP socket for SEND took the PDP
path in postoffice_can_send. For an opened connection that created a
PDP session and stored it as the socket's handle, so its sends and
receives failed afterwards (pspautotests net/adhoc/pair/ptppoll). A PTP
socket that isn't established now just isn't writable.

PES 2009 calls sceNetApctlGetState first and only calls sceNetApctlInit
when it fails with 0x80410a0d. We returned success, so Init was never
called, apctl's state never advanced and the Netconf dialog waited on
"Connecting to the access point" forever. A PSP returns 0x80410a0d before
Init and after Term (pspautotests net/adhoc/apctlinit).
After that the game polls sceNetGetLocalEtherAddr until it succeeds, which
we only allowed in ad hoc mode. Also allow it once apctl has connected. It
still fails with apctl initialized but not connected, as the test shows.

PollSocket and deleting all sockets move into RelayTransport and

No change in behaviour, except that a relay poll asks the postoffice

On Android the render thread runs the UI, and surfaceDestroyed waits for
it, so slow storage (SAF especially) there stutters and can become an ANR.
- Store: only check whether the game is installed when an install or
uninstall finishes, not every frame.
- Savedata: read the modification time with SIZE on the GameInfo worker.
The popup asked for it every frame, and each button on first draw.
- FirmwareScreen: scan the NAND, and erase it, on a worker thread. It
rescanned on every RecreateViews, which is after every popup.
- GameScreen: look up the installed update, plugins and what the firmware
can play on a worker thread. They ran on every RecreateViews, which
happens as each piece of game info arrives.
- LaunchFile: wait only for the file type, and for PARAM.SFO just in the
cases that use it.

When the game gives up on a join (game mode timed out, or it
disconnected), a join still queued isn't sent anymore, and the rest of
the server's answer to one already sent is dropped: its players, and the
BSSID that came last and connected us. Players joining a group we've
just left (before the server knew) are dropped too, instead of staying
in our peer list.
Replaces the previous fix, which only dropped a late BSSID: on Windows
the join itself was still queued when game mode timed out in
net/adhoc/gamemode, and went out after it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
When entering game mode timed out before the server's group BSSID came
back, the late BSSID was taken for a normal group's, and the state went
to CONNECTED: every later CreateEnterGameMode then got ALREADY_CONNECTED.

--speed=PERCENT runs a --realtime headless at an alternate speed (speed
control while connected is allowed for it), and pacing follows it. The
ad hoc tests now run at 800%, which takes their part of test.py -g from
about 71 s to 12 s; only local network round trips stay real time.
test.py also gives each ad hoc test run its own --port-offset: a
connection the previous run made with the same ports is still in TCP
TIME_WAIT, and connecting again failed with EADDRINUSE once runs came
close together.

The timeouts of blocking socket calls and of entering game mode are the
PSP's, but they were measured on the wall clock, so they came out
shorter in PSP time whenever emulation ran fast or slow. The wait for

clock.

On macOS, calling connect() again on a socket whose non-blocking
connect was refused returns EISCONN; only SO_ERROR and a failing
getpeername tell it apart from a connection. PtpConnect took EISCONN at
its word, so in P2P mode a connect to a port nobody listened on
"succeeded", and the game sent into nothing. Check getpeername first
and use SO_ERROR when it fails.
PollSocket also reports a refused connect as DISCONNECT now, as a PSP
does (net/adhoc/poll), instead of only ever noticing success.

PdpCreate, PtpOpen and PtpListen use the local MAC whatever the game
passes (a stale MAC from an old savestate would otherwise break them),
but they did it by overwriting the game's copy. A game that passes
someone else's MAC from a table then has its own MAC in that table.
pspautotests net/adhoc/pdp passes its "other" MAC to PdpCreate and later
sends to it; every one of those sends came back to itself.

A PSP stays in its group through sceNetAdhocTerm and sceNetAdhocInit,
and matching keeps working; only the sockets go, and calls on them

A PSP sends its master every 12 ms after the initial sync, and a peer's

GetPtpStat only looked at a connection in progress 33 ms after the last

a workaround for Pocket Pool). DISCONNECT comes 650 ms after

CancelTarget on an incoming P2P request marked the peer timed out. It

- CreateReplica for the same MAC again gives ALREADY_CREATED. The check

GetPdpStat 1, GetPtpStat 2, PollSocket 18, GetScanInfo 2, GetPeerList
and MatchingGetMembers 4 (no longer a 100 us reschedule),
MatchingStart 416 instead of 30 ms, sceNetAdhocctlTerm 154,
sceNetAdhocTerm 10 and sceNetTerm 209 instead of 10 ms each,
GameModeUpdateMaster 80, UpdateReplica 9.
- Game mode data goes out every 12 ms, not every 0.5 ms.
- DISCONNECT comes 640 ms after ExitGameMode, not 105 ms.
- CONNECT after a Join no longer waits for a peer: a PSP delivers it

The u64 total length made both context structs 8-aligned, while the

A PSP checks a PTP connection's oldest unacknowledged data every
rexmt_int, counting from when the connection was established, and drops
the connection at the first check where that data is older than
(rexmt_cnt + 1) * rexmt_int. A matching peer times out keepalive_int *
init_count after its last keepalive, checked all the time instead of on
the console's own keepalive tick, which could add up to an interval.

From the basic and lifecycle pair tests, recorded on two PSPs:
- GetNameByAddr for the console's own MAC gives NO_ENTRY, and
GetAddrByName doesn't find the console itself.
- GetPeerInfo with a size too small for the entry gives INVALID_BUFLEN.
- A PTP connection accepted over the relay reports the peer's port as
the game sees it, not the relay's offset port.
- The built-in server makes up a locally administered BSSID for each
group, which stays when the creator leaves. It was the MAC of the

The vanish pair test (recorded on two PSPs) now passes on both sides,
over the relay:
- From the Disconnect call, a console's PDP and PTP sends succeed and go
nowhere, and nothing reaches it.
- A PTP connection to a peer that has left the group fails with
DISCONNECTED after rexmt_int * rexmt_cnt. Relay sockets now get their
retry settings (and are zeroed), and an accepted one counts as
connected.
- Matching data to a peer that has left gets DATA_TIMEOUT after the
retransmissions instead of a DATA_ACK.
- The matching timeout for a silent peer is keepalive_int * init_count,
plus MATCHING_TIMEOUT_EXTRA_US (0) to tune for internet latency. It
was (keepalive + rexmt) * count + 500ms, later than a PSP's.
