The keysym-to-engine-key rule lived in ibus.c, xim/xim.c and gtk/main.c,
and the copies disagreed: GTK sent keypad digits as special keys while
IBus and XIM sent '1'..'9'. Modifiers were rebuilt bit by bit in two
places although Mmask already is the X core layout; only the virtual
Super bit (26) that GDK and IBus set needs folding. ipckey/ipcmod in
ipc.c serve the daemon, the module and the tests.
bench.sh copied ipcpath() and the IBus address-file discovery into shell,
although the benchmark client only speaks IPC; retrying the client itself
is the readiness test. It also forwarded arguments to a daemon that takes
exactly one. README claimed Enter confirms the selection, but Enter and Tab
commit the reading unless a candidate was moved to.
Only ibus.o needs the D-Bus and xkbcommon flags, so give them the same
per-object scoping as the popup and XIM objects. The docker targets used
-B, which recursive makes inherit: the daemon was linked three times and
the live tests built twice per docker-check. gtk/Makefile repeated the
module-directory check and cache refresh in install and uninstall.
bits_per_rgb_value is the colormap component precision, not the pixel
layout; the NVIDIA driver reports 11 for its ordinary x8r8g8b8 visuals,
which left the popup disabled there. Depth, class, masks, byte order and
the pixmap format already pin the layout that putimage writes.
Avoid reading inactive Str storage when deciding whether to publish a redraw. Keep the focused engine suite compact by retaining one case for each page, navigation, and empty-result invariant.
