RaiseOn suspends the target, reads its context and, while it is in host
code, resumes it and samples again after SwitchToThread. On a 16-core
Ryzen 9 5950X (Windows 11 22H2) that resampled the writer of
guest_raise_in_host_code about every 10 us before it could run: in the
raise that hung, 4,989 samples over 50 ms all found it in ucrtbase, so
the 50 ms host-code limit ran out and the handler was redirected into
fwrite, where it deadlocked on the stream lock (the test timed out at
30 s on every run). In a passing raise the samples sat at one RIP for
14,695 of 14,703 samples and the raise took 145 ms.
Spin for 20 us before each new host-code sample, so the target gets to
leave host code. With that, guest_raise_in_host_code passes 5 of 5 runs,
no raise is redirected in host code, and the longest raise is 0.46 to
0.53 ms. Other samples keep SwitchToThread.

The debt entry says the rule follows a static reading of the console's
wcsncat_s in libc.prx, that wcscat_s inherits it unread, and that the
narrow strncat_s keeps a wider rule, as asked in review.

Initialize, Terminate, UpdateStatus, GetStatus, Open, OpenA, Close and
GetResult run the common-dialog state machine. There is no PSN profile
UI, so Open and OpenA finish at once and GetResult reports result 0,
userAction USER_CANCELED and the caller's userData, as shadPS4 does when
its window is dismissed.
Paths where shadPS4 and the other common dialogs here return different
errors throw, and so does a param whose size or mode does not match the
shadPS4 layout. The common-dialog codes the library uses are added to
libSceCommonDialog/CommonDialog.hpp.
Every import lookup walked the lease out from the containing range to find
the run of continuing registry ranges, which is linear in the run length.
That walk depends only on the lease snapshot, the containing range and the
import window block, so its first and last index are now memoized per
thread under a weak reference to the snapshot, the range index, the window
and the window's low end. APS5_NO_RUN_MEMO walks every time.
Everything that depends on other state runs on each call as before: the
largest size, the budget, the failed blocks, the remembered refusals and
the halving block search. importRunBounds returns the chosen indices, so
sameRange, runCovers and the whole-run lookup in importAllocation compare
against the lease without copying the run's range pointers.
importRunFailureShrinkTests records a failed 8 MiB block between two
lookups on an unchanged registry and requires the run to shrink to its
4 MiB blocks. importRunGrowthTests and importRunReplacedTests check that a
run grows and shrinks when its ranges are registered or replaced.

Delegate sceNpCommerceDialogInitializeInternal to sceNpCommerceDialogInitialize, sharing dialog state and returning COMMON_DIALOG_ERROR_ALREADY_INITIALIZED on duplicate initialization, following shadPS4. Add regression tests in GuestNpCommerceDialog covering initial, duplicate, and post-termination initialization, and update technical debt documentation.
Adds the PPSA01746 measurements on an RX 6400 to the existing entry: the awaited word already holds a slot address when the wait starts, and the RELEASE_MEM the driver saw was queued but not shown to land.

Read the clock of a libkernel condition attribute, returning
SCE_KERNEL_ERROR_EINVAL for a null or destroyed attribute as
scePthreadCondattrSetclock does, after FreeBSD 11.4 libthr's
_pthread_condattr_getclock. A null clock pointer throws.
On a PS4 Pro with firmware 10.71 a successful sceJpegEncEncode returns the
size of the JPEG it wrote, the same value it stores in the output info,
and it does so when the output info pointer is null too. AnyPS5 returned
0, so a title that takes the size from the return value got an empty
image. The guest test now checks the returned size against the output
info.

The initial user reported keyboard type 0, which the converter maps to IME type 0
and then rejects, so a title reading the layout still could not use it. Report 20
for sceUserServiceGetKeyboardType, which the owner's table maps to IME keyboard
type 4 (English, US); the Japanese and Traditional Chinese input variants stay 0.
Tests and both debt entries updated.
On macOS, shutdown(SHUT_RD) on a UDP socket that was never bound does not
wake a thread blocked in recv on it, so sceNetShutdown left the receiver
hanging. Use the receive wait that Windows already has: block on the
socket table until the socket gets a local port or is shut, then poll.
On macOS an unbound socket reports port 0 from getsockname, so the check
looks at the port instead of the Winsock error.
Ported from #8658.

All four exports threw. The ownership calls follow fchown: owner and
group 0 and the unchanged value are accepted and any other value
throws. The path is looked up first with stat, lstat or fstatat, as
FreeBSD 11's kern_fchownat does, so a lookup error is returned before
the owner is checked. fchownat rejects flags other than
AT_SYMLINK_NOFOLLOW with EINVAL. linkat passes AT_FDCWD and absolute
paths to link and rejects flags other than AT_SYMLINK_FOLLOW with
EINVAL; a relative path with a directory descriptor and a symbolic
link source without AT_SYMLINK_FOLLOW throw. On Windows a symbolic
link source is detected with the file attributes, since libstdc++
there reports it as a regular file.
