Two frontends read the same two numbers, and wl.c carried four lines of
comment to say why it kept its own copy of them. IBus and text-input-v3
number the purposes alike because both took them from GTK, so the header
is where they belong and the explanation goes away with the copy. hidden
stays in both files: one asks about a context, the other about the seat.

An IBus client throws away a dead key its engine did not take — the GTK
module's own comment says so, and Qt does the same — so é and ü were
lost in every IBus application, while XIM composed them with a table of
its own. That table moves to compose.c, which both frontends now use;
xim.c is the shorter for it.
A finished sequence is text, not a key: the engine is asked to hand back
what it had pending, and the composed text follows it, so the composed
character can no longer land before the syllable typed before it.
A context that had not sent FocusIn had every key rejected outright, so
the input method was silently dead in a client that omits or delays it,
and in the documented case of two applications whose focus events cross.
ibus-daemon and fcitx5 both treat a key as focus; strans, which plays the
daemon here, now does too. A release still does not focus, and the
engine's own owner rule is unchanged.
libibus looks for the file under WAYLAND_DISPLAY when a session has one,
DISPLAY only otherwise; strans always used DISPLAY, so in a Wayland
session it wrote <machine-id>-unix-0 while every IBus client looked for
<machine-id>-unix-wayland-0 and found nothing. The machine id now comes
from D-Bus's copy first, as libibus reads it, and a host with neither
file gets libibus's own "machine-id" rather than a daemon that dies.
Cclientpreedit was a one-bit mask that every producer set as "want ?
Cclientpreedit : 0" and every consumer masked out again; nothing else
was ever going to join it. Keyreq carries clientpre, an int that says
whether the client draws the preedit, and the engine and the XIM
context keep it under that name.
ibusinit unwound its server and un-registered its atexit handler on a
failure whose only sequel was ibusthread dying anyway; now each failure
dies with its own message, and the test that existed to walk that
unwind goes with it. Also gone: an empty watch-toggle callback where
libdbus takes nil, Maxconns as a second name for Maxclients, fprintf
and strerror where the rest of the daemon says fprint and %r, USED()
where a parameter can simply be unnamed, a second findcontext() for the
Properties branch, and emitcommit() taking a connection and path apart
from the context that has both. Ownerpoll lives once, in dat.h.
server_test, ibus_test and xim_adapter_test each ran their own copy of
the same alt loop that stands in for imthread, and two of them had
private checkstr/checkenginepreedit variants. test_util.c now provides
Pump (trace, optional hold on a chosen op, stop) in its own proc so a
test may block in socket I/O while the engine runs, and test.h declares
the engine hooks once; every .c includes dat.h and fn.h itself as the
rest of the tree does. server_test's three copies of fixture setup and
teardown became serverbegin/serverend.
Six handlers built method returns by hand and only two of them checked
for a nil message; reply() builds them all and dies on OOM like the
rest of the daemon. DBusError objects were initialised and freed but
never read: libdbus accepts nil. Properties.Get always errored, so it
is one line in onmsg; the introspection XML served nobody (libibus
never asks) and had to be kept in sync by hand. Ibushinthidden was not
an IBus hint, so that term of hidden() never fired. writeaddr uses the
syscalls directly and the address file's dev/ino is the ownership
proof; buildaddrpath makes the directory in place. An empty
UpdatePreeditText goes out only to the context that shows a preedit.
