0f77e0e9ac engine: the chosen candidate is what the client shows 
The preedit sent back to the owner was always impre(), the reading, so
かく stayed underlined in the application while the popup showed 書く and
Enter inserted 書く.  Nothing was hidden -- the popup had it -- but the
text did not stand where it was going to land, and mozc, fcitx5 and kime
all put the candidate inline.

Only the reply changes.  impre() still answers the reading everywhere it
is the reading that is wanted: commitim, the okurigana mark, the seed
Ctrl+H takes, and snapshot, so a popup that draws the preedit itself
keeps the reading above the list where it says something the highlighted
row does not.  Consulting im.sel here is safe where consulting it inside
impre() would not be: transstr memsets a local Im, whose sel is 0 and not
-1, and this reply only ever reads the engine's own.

Nothing in the suite pinned the old answer, so the test is new.

761428dbc4 engine: a Hanja word shows once, as every other candidate does 
hanjaquery was the only query that assigned dictprefix's output straight
into im.kouho; emojiquery, dictqjp and katakouho all go through
addkouho, which is the only place a duplicate is dropped.  Two readings
under one prefix can carry the same word, and 198 of the 61,479 one- and
two-syllable prefixes in hanja.dict do: 게 listed 偈句 at rows 8 and 9,
개근 listed 皆勤狀 twice in five.

1bc0ba0491 build: the parent make knows what the daemon is built from 
../strans listed no prerequisites, so once the file existed make held it
up to date whatever changed under it: touch strans.c, run
make -C tests check-live, and it planned no compile at all and smoked a
stale daemon.  The sibling rule for the GTK module answered it by naming
three of its sources, which is the parent Makefile's list copied and
already short of gtk/Makefile.  Neither list is needed -- ask the parent.

591029237e test: a fixture that cannot fail needs no guard 
ximbegin took a struct ct* only to USED() it and always returned 1, so
its seven `if(!ximbegin(...)) goto cleanup;` call sites tested nothing
and three of the cleanup labels they jumped to were unreachable.
ibusbegin malloc'd one byte twice so that its two fake DBusConnections
would differ by address, then CT_CHECKed the mallocs; two bytes in the
fixture are two addresses, and nothing has to be freed.

08d0e0fec8 engine: an okurigana mark does not outlive its kana 
Shift on a romaji letter marks where the okurigana begins, and Backspace
shortened the reading through im.l->back without clearing the mark.
dictqjp only applies a mark that still falls inside the reading, so the
stale index lay dormant while the reading was short and fired again the
moment it grew back past it: kaKu, Backspace, then nzi offered
噛んじ 兼んじ 漢字 幹事 感じ, where kanzi typed plainly offers 漢字 first.
A Backspace edits the reading, so the split marked in it is gone.

d3d46c8cb1 engine: Backspace gives the reach back before what was typed 
searchkey popped search.raw and then search.seed but never touched
search.back, so once the typed syllable was gone the query was nothing
but the client's own text: an empty preedit above a full candidate list
drawn from syllables the user had not selected, and Enter rewrote them.
With 상 written and 태 typed, Ctrl+H offered 狀態; one Backspace left
the query 상 and 128 candidates, and Enter replaced the 상 with 上 and
dropped the 태 altogether.

Undo now runs backwards through what happened -- the keys typed since
Ctrl+H, then the reach Ctrl+H made, then the syllable that seeded it --
so the same Backspace narrows 상태 to 태 and offers 太, which is also
the only way there was ever going to be to convert the syllable alone.

b08f3bb7a2 engine: nothing pending is no reading, and reaches into nothing 
startsearch let reachback walk the client's text whenever Ctrl+H found
im.sel < 0, without asking whether anything was pending, so a Ctrl+H
pressed to begin a reading took the syllables already written instead.
With the cursor after 입니다 the query became 다, the preedit showed
nothing at all, and Space committed 多 over the 다 the user had written;
typing the reading the key was pressed for gave 다한, so 입니다漢 came
out 입니多恨.  A reading is what is pending, and there is none.

The seeded reach is untouched: 한 committed with 자 pending still
converts 한자 as a word and takes the 한 back.

5d9a2a614e wl: the text before the cursor, and the runes to take back 
The surrounding_text event was taken and thrown away.  It carries the
text around the cursor with a byte offset into it, and belongs to the
activation like the content type, so it is pending until done and
starts empty at every activate.  delete_surrounding_text counts bytes
where the engine counts runes, and the frontend holds the text those
runes are in, so it measures them itself.

921e632eae ibus: the text before the cursor, and the runes to take back 
RequireSurroundingText asks the client to send its text; it arrives
through SetSurroundingText as an IBusText and a cursor counted in
runes, and DeleteSurroundingText asks for runes back before the commit
that replaces them.  The official libibus client now proves the whole
turn: 한자 typed, the Hanja key, Enter, and 漢字 arrives with the 한
taken away.

A client that has set EffectivePostProcessKeyEvent is never asked for
its text.  It reads the key's commits back after ProcessKeyEvent
returns, and a DeleteSurroundingText signal is not one of the things
that reply can carry, so the deletion would land after the text it was
meant to make room for and eat the wrong runes.

910bf51347 ipc, srv, gtk: the client's text goes over and a take-back comes back 
The engine can reach a Hanja reading back into the text the client
already holds, but only if the frontend hands that text over and can
take some of it away again.  GTK 3 has both: retrieve-surrounding
brings the text around the cursor and delete-surrounding removes runes
before it, and a widget that answers neither leaves the text empty, so
nothing is ever reached into or taken from it.

The wire grows a control frame for the text, sent like the caret only
when it changes, and one byte in every response for the runes to take
back.  That byte moves the length fields along, so the version goes to
2: an old daemon and a new module, either way round, fail the handshake
and the module falls through to GtkIMContextSimple rather than misread
a frame.

f7277f54a3 engine: Ctrl+H reaches back into the text the client already has 
Korean commits a syllable as the next one begins, so by the time the
한자 key is pressed only the last syllable is still ours: typing 한자 and
then Ctrl+H asked about 자 alone and answered 子, leaving 한子 in the
document -- the mixed Hangul and Hanja that was refused as dictionary
data, made by the interaction instead.  To get 漢字 the key had to be
pressed before typing, which no other Korean input method asks for.

A request now carries the client's own text just before the cursor, and
the reading reaches back through it as far as the dictionary still knows
the whole of it: 한 joins 자 and 대한민 joins 국.  Nothing but the
dictionary says where to stop, because a reading is syllables, so a key
holding a space or an already converted Hanja leads nowhere and the
reach ends there.  A pick answers with the count of runes to take back
first; Escape gives back only what was pending, and a query with no
candidate types only the part the client lacks.

A frontend that sends no surrounding text reaches back by nothing and
behaves exactly as before, which is what XIM will keep doing.

997e4c8d93 srv, ibus: a note the daemon lives through keeps its endpoints 
srvnote and addrnote unlinked on any note at all, and plan9port marks
SIGPIPE Ignore: notify.c:59 lists it, and signotify runs the handler
chain first and only then finds the Ignore flag and returns.  So one
broken pipe took the IPC socket and the IBus address file away from a
daemon that went on running -- measured on a private runtime dir, a
single kill -PIPE left the process in state Ssl with both files gone,
so every client that focused a widget afterwards silently had no input
method and only a restart brought it back.

libxcb writes with writev, so the note is a broken X connection away;
today xim.c's die() masks it by taking the daemon down on the same
event, which is exactly why the two must not depend on each other.

dab80b3a77 engine: a key that converts nothing is the application's 
Space and Tab convert a Japanese reading, and a reading with no
candidate to step through was committed and the key eaten.  Katakana
mode converts nothing -- katakouho adds the Katakana form only when it
differs from the reading, and in Katakana mode it never does -- so
every Space between two Katakana words was swallowed and had to be
typed twice: カク<Space> committed カク and left no space, and the
second Space passed through only because nothing was pending any more.

Committing and passing the key on gives the space back.  Hiragana is
unchanged wherever the reading has kana, since the Katakana form is
always one candidate there; it changes only for a reading that made no
kana at all, かx<Space>, which now commits and spaces too.

d9e27e8b01 engine: a Hanja reading answers with the words it begins 
hanjaquery matched the reading exactly, so a word was reachable only
once every syllable of it had been typed, and the popup went blank on
the way there.  Measured over map/hanja.dict's 187,304 readings:
95,024 proper prefixes of a word answer with nothing today, and 66,731
of those are the keystroke just before the word completes -- 대한민 is
one, so 대한민국 looks absent until the last key lands.

dictprefix walks the entry at a node before its children, so the
reading's own conversions keep their place and the words follow: 34,441
readings gain candidates and none of the 187,304 has its existing order
changed.  A jamo reading is untouched, since the two keyspaces do not
meet and ㅁ has no children.

5abd885e11 data(symbol): a prefix owns its slots only through its own row 
map/symbol.src:12 says "Bare 1-9 choose from a prefix search; keep digit
aliases in matching slots", map/README:55 repeats it, and both
tests/engine_test.c:1001 and tests/mkemoji_test.py were written to it.
None of it happened.  dictprefix ends in below(), which returns a node's
own words first and then its children in rune order (dict.c:29-39), and
under `^` the punctuation sorts ahead of the digits:

	^ gave  ⁽ ⁾ ⁺ ⁻ ⁰ ¹ ² ³ ⁴ ⁵ ...
	_ gave  ₍ ₎ ₊ ₋ ₀ ₁ ₂ ₃ ₄ ₅ ...
	< gave  ← ♥ 🫰 🫶 ≤ ≠

so the file's own aliases picked the wrong character every time:

	          before   after
	^ then 1  ⁽        ¹
	^ then 2  ⁾        ²
	_ then 1  ₍        ₁
	< then 3  🫰        ♥

mkemoji has no bare `^` row to emit, because no source row claims `^` as
an alias -- the prefix exists in the trie only as the parent of `^1`..`^9`
and `^(`..`^n`, and a parent has no words of its own.  Giving the nine
superscripts `^` as a second alias, the nine subscripts `_`, and ←≤♥≠ `<`,
makes build() group them in source order and emit three rows:

	<	← ≤ ♥ ≠
	^	¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹
	_	₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉

which is what engine_test.c:1001's fixture has said all along, and the
first thing below() now returns.  Nothing is lost: `^0`, `^(`, `^i` and
their kind still answer their own key, `0` is not a selection key so it
still extends the query, and addkouho drops the duplicate when a child
repeats what the parent already offered.  Three rows on 18953.

tests/mkemoji_test.py was asking the wrong question.  It checked that the
first nine `^` keys in the file are `^1`..`^9` -- true before and after,
and decided nothing, because the file's order is not the trie's.  It now
checks the row the engine actually reads, and fails without this change
with a bare KeyError on `^`.

What this does not cover: `+1` and `-1`.  They are not slot aliases, they
are words -- plus one, minus one -- and ➕ and ➖ are the right first
answers to `+` and `-`.  👍 is slot 3 of `+` and reachable there.

a351f50308 engine: じ is keyed j, the letter SKK types it with 
okuriletter() puts じ in the z row, so dictqokuri can never build a key
ending in j.  map/kanji.dict has 17 of them, and 8 have no z twin at all:

	before                     after
	shinjiru  死んじる           信じる 死んじる
	tojiru    (nothing)        綴じる 閉じる
	tsuujiru  (nothing)        通じる
	shoujiru  (nothing)        生じる
	toujiru   問うじる           投じる 問うじる
	koujiru   乞うじる 請うじる    高じる 乞うじる 請うじる
	gozonji   御存知             御存知 御存じ
	majiru    混じる 先じる       交じる 混じる

信じる, 閉じる, 通じる, 生じる, 投じる, 交じる: the dictionary holds every
one and the engine could reach none.  What it offered instead was the
next split down -- しんじる falls back to しn, so 死んじる is what the
popup shows for 信じる, and it is the only candidate.

The letter is not ours to choose; it is the one the SKK dictionary was
keyed by, which is the one the user typed.  Real SKK carries both spellings
where both are typed, and here that is 9 of the 17 -- えんj/えんz, かんj/かんz
and their kin, identical values on both.  Those 8 z rows go unreachable and
lose nothing, because their j twin says the same word.  ま is the one pair
that differs, まj=交 混 against まz=混 先, and both stay reachable: じ takes
the j road and ぜ/ず keep the z one.

	mazeru    混ぜる 先ぜる      unchanged
	kanarazu  必ず ...           unchanged
	mizu      水 見ず            unchanged
	dekizu    出来ず             unchanged

The z row keeps ざずぜぞ, so nothing that is not じ moves.

What this does not cover, deliberately: ち.  kanji.dict has 7 keys ending
in c, from users who typed "chi", and okuriletter puts ち in the t row.
Giving c its own row would have to take ち out of t, and t is where the
larger entry lives -- おt is 落 折 負 追 against おc's 落 alone -- so the c
rows stay unreachable and lose nothing.  づ needed no such choice: it is
in the d row, もとd is 基, and もとz is its duplicate.

c9c01fdeb9 engine: a page key on an untouched list turns the page 
movekouho() answers every one of Up, Down, PageUp and PageDown the same
way when nothing is chosen yet -- `if(im.sel < 0) im.sel = 0;` -- and
delta is thrown away.  For Up and Down that is right: the list is drawn
with no cursor, so the first move takes the first candidate.  For
PageDown it is not, because there is no page state to move; pagefirst()
derives the page from im.sel alone, so selecting candidate 1 leaves the
page exactly where it was.

dictqjp() leaves sel at -1 on every keystroke, so a Japanese list is
always untouched when it first appears.  Type かく, look at its thirty
candidates, and press PageDown for the next nine:

	                     before          after
	かく, PageDown        sel 0, page 0   sel 9, page 9
	かく, PageDown twice  sel 9, page 9   sel 18, page 18
	かく, PageUp          sel 0, page 0   unchanged
	かく, Down            sel 0, page 0   unchanged

Nothing on screen answers the first press but the highlight appearing on
row 1, and the page turns only on the second.  fcitx5 pages on the first,
because its candidate list carries a page of its own and
toPageable()->next() does not touch the cursor
(ref-fcitx5-hangul/src/engine.cpp:326-336).  strans has one number where
fcitx5 has two, which is the right trade for nine rows and 128
candidates -- but then the number has to move by a page when a page key
asks for one.

`delta == Maxdisp` rather than `delta > 0` is deliberate: Down must still
land on candidate 1, and writing it the loose way fails both this table
and engine/japanese-candidates at engine_test.c:1198, where the language
switch takes 漢字 and would take 幹事 instead.  PageUp from an untouched
list still clamps to 0; there is no page above the first.

searchkey shares movekouho, and is unaffected: emojiquery and hanjaquery
both end in selectfirst(), so a search list is never untouched while it
has candidates.

bfcd9f6786 engine: a modifier makes a special key the application's 
Backspace, Enter, Tab, Escape and the arrow and page keys are matched by
keysym alone -- strans.c:852, 875 and 882 name them, and searchkey names
the same set at strans.c:746-786.  Every other key above Kspec falls
through to the catch-all at strans.c:898, `ks >= Kspec || chord(mod)`,
and goes to the application.  So the special keys strans knows by name
are the ones it takes under a modifier, and the ones it does not know are
the ones it hands over.  That is backwards: a named special key under a
modifier is exactly the one the application has a binding for.

In Korean a syllable is pending for nearly all the time anyone is typing,
ko.c holding one and no more, and the guards at strans.c:876 and 883
return 0 only when nothing is pending -- so the key is eaten precisely
when it is wanted.  Type 안녕하세요 and reach for Ctrl+Backspace to take
the word back: 요 loses ㅛ, then ㅇ, and the word itself goes on the third
press.  Ctrl+Enter in a chat box, Ctrl+Tab in a browser and Ctrl+PageDown
in either are the same key eaten by the same lines.

	                            before               after
	Korean 가, Ctrl+Backspace    eaten, pre ㄱ         passed, commit 가
	Korean 가, Alt+Backspace     eaten, pre ㄱ         passed, commit 가
	Korean 가, Super+Backspace   eaten, pre ㄱ         passed, commit 가
	Korean 가, Backspace         eaten, pre ㄱ         unchanged
	Korean 가, Shift+Backspace   eaten, pre ㄱ         unchanged
	かく, Ctrl+Enter             eaten, commit かく     passed, commit かく
	かく, Ctrl+Tab               eaten, commit かく     passed, commit かく
	かく Space, Ctrl+PageDown    eaten, sel 0 -> 9     passed, commit 確
	かく Space, PageDown         eaten, sel 0 -> 9     unchanged
	かく Space, Shift+Tab        eaten, sel 0 -> 30    unchanged
	Ctrl+E sm, Ctrl+Backspace    eaten, query s        passed, commit sm
	Ctrl+E sm, Backspace         eaten, query s        unchanged

chord() cannot be reused here.  It is `(mod & ~Mshift) != 0 && mod !=
Mctrl` and the exclusion is deliberate, since Ctrl+letter is strans's
whole command set and chord() has to let plain Ctrl through.  The rule
this needs is the other one -- any modifier that is not Shift -- and
Shift must stay in: Shift+Tab cycles the candidates backwards, pinned by
engine/candidate-completion and engine/emoji-navigation at
engine_test.c:914 and 1649, and Shift on a Korean key is what makes ㅃ.

One line serves both paths because it sits above the searchkey dispatch,
and it has to sit below the switch at strans.c:829: 한자, 한/영, 変換 and
無変換 arrive as keys above Kspec and are rewritten there into the Ctrl
chords they stand for.  Above the switch, 한자 would commit and pass
instead of opening the Hanja list; below it, pressing it with Ctrl held
still opens the list, because the switch sets the modifier itself.

What this does not cover: Space, which is below Kspec, so searchkey:763
still picks a candidate on Ctrl+Space inside a search.  transition tests
!(mod & ~Mshift) for its own Space at strans.c:865, so the two disagree
there.  Left alone: what Ctrl+Space should mean wants its own argument,
not a widened guard.

3f8f51adf4 engine: typing counts as being heard from 
takelost's own comment says the context the engine was taken from "gets
that text back when it is next heard from", but it was wired to the
Keyrelease and Keyreset arms only.  The Keypress arm opens with
sclear(&lost), so the one way a context is most obviously heard from --
somebody typing into it -- is the way that threw its text away.

Compose in A, type in B before A's focus-out arrives, then go back to A
and type: A's reading is gone rather than handed back.  That interleave is
not exotic here, it is the premise takelost exists for.  Focus-out can
arrive after the next context's keys, which is why the engine changes
hands with text still pending; and a context whose focus-out is still in
flight can be typed into again just as easily as it can be reset.

	engine_test.c: the taken owner types and gets its reading back:
		want "か", got ""

The call has to go above the owner switch, because that switch's own
sclear(&lost) is what destroys the text -- putting it after the switch
instead fails the same line.  Above it, the order also comes out right:
the recovered reading is appended to the commit first and whatever the key
itself commits follows it.

What this does not cover: there is one lost slot.  A third context taking
over between the two still destroys the first one's text for good, and
widening that means an array where a single Str is now -- a new structure
for an interleave that needs three contexts and no focus-out from any of
them.  Left as it is.

ibus_client_smoke was pinning the defect rather than merely missing it: it
required exactly three commits on context a, and its handler rejected any
commit text but か, so the recovered reading tripped both.  Bumping the
count would have been a constant with nothing behind it, so the take-back
got a stage of its own and the text is asserted -- the official libibus
client now watches the whole thing, and without the fix reports

	retook=0

One assertion was written and then deleted.  takelost now runs on every
key rather than only on the two lifecycle ops, so re-committing the same
text on every keystroke looked like the hazard worth pinning, and "the
reading comes back once" went in beside the others.  Making takelost skip
its lostowner = nil left all 90 passing: the owner switch reassigns
lostowner to the context it just displaced, so lostowner is never the
owner of the next key, and the hazard is unreachable.  An assertion that
cannot fail is decoration, so it is not in the tree.

90 unit, check-live, check-stress and valgrind clean.

8ebe6b32df engine: a mode mark does not outlive its owner 
The mark a mode switch leaves, from 6a6749e, is cleared at the top of
transition(), so the next key takes it away.  Nothing takes it away when
there is no next key.  reset() clears the pending text, the raw state, the okurigana split
and the search, and leaves modemark alone -- so a release or a lifecycle
reset flushes everything the popup was showing except the one thing that
is still drawn.

Then samedraw() sees a picture identical to the last one and redraw()
sends nothing, and win.c only ever unmaps from a Drawcmd (winshow, the
sole caller of both map and unmap).  So the popup stays.  Press the 한/영
key, type nothing, and alt-tab: 한 sits above every window, override
redirect and typed as a tooltip, until the next keystroke in any
strans-aware field -- which may be minutes.  Counted on a private X
server, viewable override-redirect windows:

			before	after
	at rest		0	0
	after Ctrl+S	1	1
	after letting go	1	0

reset() is where it belongs rather than the release arm, because the mark
is one more thing that is pending: it is drawn only when nothing else is
(snapshot), and it means the switch has not been typed on yet.  Clearing
it there is safe for the switch itself only because transition() zeroes it
at the top and setlang() runs after flush() -- reset() is reached through
that flush, before the new mark is set.  That ordering is not obvious, and
it is exactly what engine/direct-language-modes already asserts at
engine_test.c:584; breaking setlang so a switch marks nothing fails that
line and the new ones together.

Not a Wayland defect: wl.c's leave() calls hidepopup() unconditionally
after the release, so its popup was already coming down.  X11 was the
frontend that trusted the picture.

The new case goes in engine/direct-language-modes beside the mark
assertions that were already there, and drives imhandlekey rather than
transition, since the defect is on the owner-release path.  Without the
fix:

	engine_test.c:619: check failed: draindraw(&dc) > 0

that is, the engine published no picture at all.  Its second line needs
its own reason to exist, so it was checked by removing the fix and making
samedraw() answer 0 for everything: the picture then arrives and still
carries the mark,

	engine_test.c:620: want 0, got 1  (dc.pre.n)

which is the assertion that would otherwise have been decoration.  The two
setup lines are load-bearing too -- with setlang marking nothing they fail
rather than passing vacuously, since an empty picture equal to the last
one is never sent.

90 unit, check-live, check-stress and valgrind clean; the count is
unchanged because the case joined a test that already existed.

b61c04b280 gtk: an entry hidden the older way is private too 
isprivate() reads the GTK input purpose and nothing else, but the purpose
is not the only way an application marks a password field, and it is not
the older one.  GTK 3.24.52, measured:

	gtk_entry_set_visibility(entry, FALSE)	purpose stays FREE_FORM
	gtk_entry_set_input_purpose(PASSWORD)	purpose PASSWORD

so an entry hidden the first way looks like ordinary text to the module.
This machine runs one.  /usr/libexec/xfce-polkit, the XFCE authentication
dialog, is up right now under GTK_IM_MODULE=strans, and its binary calls
gtk_entry_set_visibility and never gtk_entry_set_input_purpose, so every
password typed into it goes through the engine.  Against the real daemon,
in Korean mode:

	typed hunter2		stored ㅗㅕ숟ㄱ2
	typed correcthorse	stored 책ㄱㄷㅊ쇅ㄴㄷ
	typed P4ssw0rd		stored ㅔ4ㄴㄵ0ㄱㅇ

The field draws bullets, so nothing on screen says why the authentication
failed -- except the pending syllable, which is drawn as itself: three
keys into such an entry the old module leaves 한 on screen where the
field should read ●●●.  With this it reads ●●●, and the entry holds gks.

set_visibility sends the input context no signal, so the question cannot
be answered where the purpose is, in init and notify::input-purpose.  It
has to be asked at the key, of the client window, which is the entry's
own: gdk_window_get_user_data on it returns the GtkEntry.  fcitx5-gtk asks
it the same way in all three of its GTK versions -- gtk3/fcitximcontext
.cpp:1155-1162, under the comment "seems visibility != PASSWORD hint".

It costs one field read and one type check per key, on a path that then
does a socket round trip anyway.  It does not cover XIM: that protocol has
no attribute for this, and no fcitx5 frontend answers it either -- only
its GTK and Qt client modules do -- so an X client reached over XIM still
composes in its password field.  Nor does it notice a "show password" box
switched off in the middle of a composition: there is no signal for
visibility, so the pending text stays in the daemon until the next focus
change.  Noticing that needs a signal connection on a widget the module
does not own, which is a bigger thing than the hole is.

The test is a live one and it earns its line: with the fix removed it says

	gtk_live_test: hidden-entry key reached daemon or did not commit

Both guards were checked by removing them.  Without GTK_IS_ENTRY the run
takes a Gtk-CRITICAL and fails; without the im->win test it exits 139, on
the stalled-peer context, which never gets a client window.  An ishidden
that always answers yes fails earlier still, at the initial protocol
frames.  Breaking the test's own helper so it hands back the toplevel's
window instead of the entry's fails too, which is what says the assertion
watches the right window rather than merely counting no events.

That count is the one thing that had to be made deterministic.  A new
client window invalidates the caret, and the fake daemon records that
frame on its own thread, so sampling the event count straight after
set_client_window raced it: 2 failures in 8 runs.  The block now waits for
that frame and names it, and there were 0 in 20 after.

90 unit, check-live, check-stress and valgrind clean.

dadda19b3a wl: a key the engine takes is ours to repeat 
grabrepeat was an empty body, and under the grab the compositor feeds the
client nothing while a key is down: one press, then only repeat_info,
leaving the repeat to whoever holds the grab.  So a key strans ate acted
once however long it was held.  Hold Backspace over a syllable and one
jamo goes; hold a jamo key and you get one where every other window gives
four a second.  X11 has none of this -- the server auto-repeats and xim.c
dispatches every press -- so the same keyboard behaved differently
depending on which frontend the window went through.

Under headless sway, which advertises repeat_info(25, 600), holding
Backspace 1.5s over 라 with 가가가나다 committed behind it:

	before	preedit 라 -> ㄹ, and no key at the client at all
	after	preedit 라 -> ㄹ -> empty, then 9 BackSpace at the client

fcitx5 and kime both keep driving the repeat after the engine stops
wanting the key, and both then must send a release before every press, or
the client sees a key held down and starts a repeat of its own on top of
theirs.  That machinery exists only to undo the choice that created it.
strans does not need it: forward() already hands a key the engine did not
take to the client as a key, and the client repeats that correctly -- the
same hold with nothing pending, which takes that untouched path, delivers
24.  So the rule is one sentence.  strans repeats what the engine takes;
when the engine stops taking it, presskey has already passed the key on,
the deadline is dropped, and the client repeats it from there.  9 against
24 is that handover: driving every tick here would have made them one
number.

It costs one pause of the client's own delay, 600ms, where the preedit
empties.  It buys no release-and-press fiction anywhere in the file, no
second repeat engine, and no timestamp arithmetic -- exactly one key is
forwarded per hold, so there is no run of stale timestamps to mend.

nsec() is gettimeofday, which steps; a deadline wants the clock ipc.c
already uses.  The owner poll stands down while a key repeats, because the
repeat's own Keypress carries our owner and takes the engine back, so it
would have nothing to find.

Arming needs the engine and cannot be reached from the unit suite; ending
a repeat can, and a repeat outliving its key is the worst this could do.
wl/repeat-ends was checked by breaking it five ways -- a constant rate, a
constant delay, the empty body back again, the key's own release no longer
ending it, and a repeat into a dead context staying armed -- each failing
only its own line.

Phases A-G unchanged at both scales; 90 unit, check-live, check-stress and
valgrind clean.  One limit worth writing down: the GTK probe prints the
BackSpace it receives and never deletes on one, on this path or on the
plain pass-through, so the phase proves the keys arrive and says nothing
about the text behind them.

62ddc2177b data(hanja): a lone consonant is a reading too 
Every Korean keyboard's 한자 key answers a lone consonant with the KS X
1001 symbol palette, and has since 한글 워드프로세서: ㅁ for ※ ○ △ ㈜, ㄴ
for the brackets, ㄹ for the units, ㅇ for the circled numbers.  strans
sends that key to the same search as a syllable -- Khanja is Ctrl+H at
strans.c:830, and startsearch seeds the query with whatever ko.c left
pending -- but every one of hanja.dict's 187286 readings is a syllable, so
the popup came up with a query in it and nothing to pick:

	ㅁ: 0 candidates
	ㄴ: 0 candidates
	ㄹ: 0 candidates
	한: 99 candidates 韓 漢 寒 限 閑 恨 旱 汗 翰 邯 罕 悍 澣 閒 瀚

libhangul ships that palette beside the Hanja table already imported here:
data/hanja/mssymbol.txt, same commit, same author, same BSD-3 terms, same
key:value:comment format -- and keyed by the compatibility jamo ko.c
already holds, U+3141 for ㅁ.  So the engine does not change at all; the
same dictlookup on the same trie now finds something:

	ㅁ: 75 candidates ＃ ＆ ＊ ＠ § ※ ☆ ★ ○ ● ◎ ◇ ◆ □ ■ △ ▲ ▽ ▼
	ㄴ: 23 candidates ＂ （ ） ［ ］ ｛ ｝ ‘ ’ “ ” 〔 〕 〈 〉 《 》 「 」
	ㄹ: 94 candidates ＄ ％ ￦ Ｆ ′ ″ ℃ Å ￠ ￡ ￥ ¤ ℉ ‰ € ㎕ ㎖ ㎗ ℓ
	한: 99 candidates 韓 漢 寒 限 閑 恨 旱 汗 翰 邯 罕 悍 澣 閒 瀚

Both scripts widen by one rule -- a syllable reading gives Hanja, a jamo
reading gives a symbol -- and hanja.src regenerates byte for byte as it
was, because upstream's own non-syllable readings are words like ㄱ자집
whose values were never Hanja and still fall out.  985 of mssymbol.txt's
987 rows survive: its ideographic space and its soft hyphen do not, since
a candidate the popup cannot draw is not a candidate, and the row format
separates candidates with a space besides.

The two keyspaces cannot collide -- one is syllables, one is single jamo --
so the 187286 existing rows are unchanged, byte for byte, and 18 rows join
them.  mkhanja takes a source list as mkemoji already does, and keeps each
upstream header, which is why the licence text now appears twice.

89 unit, check-live, check-stress and valgrind all clean.  The five new
assertions were checked by breaking the change five ways: dropping
mssymbol.src from SOURCES, letting issymbol keep a formatting character,
letting a jamo reading keep Hanja, widening isjamo to the vowels, and
making mkhanja reject jamo readings.  Each fails only the tests that exist
for it.

46ab39ab95 test: the popup's stacking and its map state are one observation 
popupabove() took the stacking order from XQueryTree and then the map
state of each child from a round trip of its own.  The daemon raises and
maps between those, in that order and in one flush, so the loop could pair
a stale order -- popup still below the client, where it was created -- with
a fresh IsViewable, and report the raise that had already happened as a
popup stacked below the client.  1 run in 25 under load, which is the worst
kind: often enough to teach you to re-run a red instead of reading it.

Widening the gap to 300ms shows it with no load at all, and shows the fix
is the right one.  Same test, same widener, 15 runs each:

	before	pass=11 fail=4
	after	pass=15 fail=0

XGrabServer is what makes the two one observation, and the widener is then
harmless because nothing can raise inside it.  Unwidened, 20 runs clean.

Nothing about win.c was wrong: the popup does go above, and the test now
only says so when it is looking at a single moment.

65066eef53 wl: an unavailable seat still owes the engine a release 
Another input method taking the seat made wlthread hide its popup and
return, leaving activeowner pointing at our context with its text still
pending, and whatever keys we had passed on still down at the client.
leave() is that cleanup and all of it: it gives the keys back, drops a
half-typed sequence, sends the Keyrelease and takes the popup down.

Nothing visible changes either way -- the compositor drops anything an
unavailable input method commits, and the next key from any other
frontend takes the engine regardless.  This is the engine left tidy, in
the one word that already means it.

0f128a46b3 wl: another frontend's picture is not ours to show 
e64e4ea took the picture out of the owner poll and argued a later take
could not show a stale one: "either our own key replaced it, or the
engine suppressed the send because our snapshot is that same picture".
The second half is the hole.  redraw() returns before it drains when the
picture has not changed, and under Wayland wl is drawc's only reader, so
every IBus interaction leaves its last picture sitting there -- the mode
mark after Ctrl+T, a hanja list, whatever was up.  Press a bare modifier
in a text-input-v3 window while IBus owns the engine: keymeaningful(0) is
false, the engine changes nothing, the send is suppressed, and grabkey's
takedraw puts the other window's candidates on our popup surface.

I could not make it visible.  checkowner() runs later in the same loop
iteration, finds we are not the owner and hides it, and both commits
leave in one wl_display_flush, so the compositor renders nothing between
them.  What is wrong is the rule: README says an IBus client under
Wayland "shows no candidates, because the popup belongs to the Wayland
frontend", and that is now true by construction rather than by luck.

leave() and flushpending() already take only while engaged, so the guard
costs nothing where it is and covers all three callers.  The drain still
happens either way, which is what keeps drawc and lastdraw in step.
Phases A-G under headless sway at both scales; the phase E hanja popup
is unchanged.

650f00812d compose: a sequence belongs to one context 
One xkb_compose_state served the whole session, so a dead key left half
typed in one window was completed by the first key in the next.  Two IBus
contexts through the real processkey(), before this:

	want length 0, got length 2; byte 0: want <end>, got 0xc3  (text)
	want 0, got 1                                              (req.op)

Context A pressed dead_acute; context B pressed e, got é, and went down
the composed-text branch instead of sending a key.  Only COMPOSING is
sticky -- xkbcommon starts over by itself after COMPOSED and CANCELLED,
which the table in compose_test already pins -- and nothing here ever
called xkb_compose_state_reset.

That static was also fed from three procs, two of them live at once, with
no lock, which xkbcommon forbids.  Reaching it needs two focused windows,
so it cannot be made to fail on demand and has no test: it goes because
the sharing goes, not because anything guards it.

So a state per frontend, each starting over when the key comes from
another context.  All are made in composeinit(), on threadmain, before
proccreate, because xkb_compose_state_new refs the table and that ref is
a plain increment --

	b160: mov (%rdi),%edx   b16a: add $0x1,%edx   b170: mov %edx,(%rdi)

-- so making a state from a shared table on two procs would race in place
of the feed.  Made before the procs exist they can still share the one
table.  An owner address that gets reused says so with composedrop: ibus
hands out a contexts[] slot again, xim can malloc an Ic at a freed one,
and wl's single context, which serves every client in turn, drops at
every activate and deactivate.

e64e4ea6af wl: the owner poll does not need the picture 
It took the engine's picture and drew it, then took the popup straight back
down: a buffer allocated, filled and attached for nothing, and for one
frame it was another context's candidates at our client's cursor.  The
drain it was doing is not needed either.  redraw() empties drawc before
every send, so the channel holds at most one picture and that picture is
always lastdraw -- what the engine wants shown now, whoever owns it.  A
later take therefore cannot show something stale: either our own key
replaced it, or the engine suppressed the send because our snapshot is
that same picture.

867c6ebe40 docs: the compositor list was six claims and one of them false 
Mainline dwl has no input method: dwl.c creates a virtual keyboard manager
and never a wlr_input_method_manager_v2, so IME there is a third-party
patch and strans falls back to XIM through Xwayland -- not what the line
promised.  Being a wlroots or smithay compositor is the wrong criterion,
which is the general lesson: the compositor has to wire the protocol up.
river and labwc do, and were checked; Wayfire, niri and COSMIC never were.

So the opening says the criterion instead of a list to maintain, and the
Run section already says how the choice is made.  The README says it once.

8a08efe2bb wl: a deactivate cannot hand the pending text back 
40fd4ab was half right and the sway run said which half.  The compositor
does relay the commit when a client merely disabled its text input while
holding the focus -- that much was read correctly out of sway -- but the
client has stopped listening by then.  On the wire, in that order:

	-> zwp_text_input_v3.disable()
	-> zwp_text_input_v3.commit()
	<- zwp_text_input_v3.preedit_string("")
	<- zwp_text_input_v3.commit_string("가")
	<- zwp_text_input_v3.done()

and the entry unchanged.  GTK3 drops global->current at its own
focus-out, and any client that follows text-input-v3 does the same, since
events between disable and the next enable are to be ignored.  So the
composition is unrecoverable there, by no fault of ours, and the commit
was a request nobody could take.

The code goes back to what it was; the comment does not.  The old one
said the compositor drops the commit, which is true only when the focus
moved, and that half-truth is what invited the change.

5cb9f69590 wl: every keycode evdev can send 
The bitmap held 256, and forward dropped anything above it rather than
passing it on, so a key the engine does not want vanished instead of
reaching the client.  Keys do live up there: KEY_FN is 0x1d0,
KEY_VOICECOMMAND 0x246, KEY_MACRO1 0x290, and xkeyboard-config maps
keycodes to <I709>, so they carry a keysym and are nothing special to us.
sway matches its bindings before it hands a key to the grab, so an unbound
one of those was lost for as long as any text field had the focus.

The whole evdev range costs 96 bytes of bitmap instead of 32.  The test
already writes the bound rather than the number, so it still says what it
said.

6d511919e8 wl: a content purpose belongs to its activation 
pendingpurpose was never cleared, and sway sends content_type only when
the text input asked for one: active_features is frozen at the enable
commit (wlr_text_input_v3.c) and relay_send_im_state tests it before
sending.  So a client that sets no content type leaves the last client's
purpose standing -- and after a GTK password entry that purpose is
password, so every key in the next window was forwarded raw and strans
looked dead there until a client that does declare one took the focus.

A purpose is per activation, as it is per context in ibus.c.  Clearing it
on activate is enough: the content type, if any, arrives after the
activate and before the done that applies both.

The sway runs could not have found this; the password client was GTK,
which always declares.

40fd4ab551 wl: a deactivate hands the pending text back 
Two things arrive as a deactivate.  When the focus moved, the compositor
sent the text input its leave first, and sway's handle_im_commit finds no
focused text input and drops the whole commit -- which is what the old
comment described.  But a client that merely disabled its text input
still holds the focus: sway relays that deactivate only in that case
(handle_text_input_disable returns early once the surface is unfocused),
so the commit would have been delivered, and half a syllable was thrown
away instead.  A GtkEntry losing the focus to a button in its own window
is that case.

XIM and IBus both hand the text back there and drop it only when the
client itself is gone -- ibus.c keeps the two apart as flushcontext and

841d93ac35 docs: the README says it once 
It had grown to 256 lines, a third of them the engine's fine behaviour
told twice and packaging trivia that belongs in the Makefile.  Every
user-facing fact is kept; the prose around it is not.  The dependency
list is one sentence and a pointer at the Dockerfile that already names
the packages exactly.

f6dd056ffb build: 9c and 9l can report again 
Both filter the compiler's output through $egrep, and plan9port assigns
that variable nowhere -- six scripts read it, one unrelated developer
script sets it.  The pipeline dies on the empty command and takes the
whole diagnostic with it, so -Wall -Wextra was decorative and a build
that failed to compile printed nothing but an exit status.  That is how
the tests' own dialect bug hid until it was hunted with a patched 9c.

Both scripts source $PLAN9/config, which the distribution does not ship,
so one line in it is the fix the scripts themselves ask for; it needs no
patching of a packaged file and covers 9c and 9l together.  The daemon it
builds is byte-identical, and with the diagnostics visible the whole tree
and every test object compile without a warning.

ad2f2fc5eb test: the xkb modifier mask and the forwarded key bitmap 
The two pure things in the Wayland frontend, in the shape the XIM adapter
test already uses: wl.c included behind one define that makes the virtual
keyboard inert, and a keymap built from a string, so no compositor and no
xkb data files are wanted.  The mask test holds Caps Lock apart from
Shift, which is what a Korean key turns on; the bitmap test holds a
release of a key we never passed on, a code the bitmap cannot hold, and
the release of everything still down when the context goes.

wayland-scanner's output is the parent Makefile's to write, as ../strans
already is.

2e1e0b9645 docs: Wayland 
One popup per session, so the frontend is picked at startup: a compositor
with zwp_input_method_v2 gets that frontend and neither XIM nor the X11
popup is started.  The answer for a user is one sentence -- on Wayland set
none of the module variables -- and the two exceptions the plan asked to
check turned out this way: GTK 4 binds text-input-v3 by itself, with
GTK_IM_MODULE unset (4.22 under sway 1.12, typed and composed), and
Chromium is beyond help either way, since it asks for text-input-v1 and
wlroots implements only v3.

The plan is deleted, as it said to be once the README described what
landed.

5664a008de wl: the candidate popup 
One wl_surface and one zwp_input_popup_surface_v2, made once; the
compositor makes them visible on activate, puts them at the text cursor
and takes them down again, so popuparea, popupposition and Caret stay
X11-only and popuplayout gets a constant area.  Two shm buffers are used
in turn, each busy from attach until the compositor releases it, because
win.c's single grow-only image would be redrawn while the compositor was
still reading it; a picture that arrives while both are busy waits for
the next release, and the engine will not send it twice.  drawthread no
longer runs, so wl.c reads GDK_SCALE itself and calls textinit after it,
since setfont reads Fontsz.  The buffer is rounded up to a multiple of
the scale: one that is not is an invalid_size error at attach, and a
preedit alone really does lay out to an odd width at GDK_SCALE=2.

drawc is taken where the engine's picture and our surface can part:
after every key, after the Keyrelease a deactivate sends, and after the
owner poll, hiding for the last two.  The poll is not an optimisation --
once another frontend takes the engine, its pictures go unconsumed and
no later send will ever say hide.

main.c now starts either the Wayland frontend or the X11 popup and XIM,
which is where the two popups would otherwise collide.

Checked by hand under headless sway 1.12, reading grim screenshots: the
hanja list for 가 with its selection and 1-9/125 marker, the emoji
search, the popup gone after Escape, and the same at GDK_SCALE=2.

4ac0625c6b wl: the input-method frontend 
zwp_input_method_v2 over one connection, in one process: activate,
deactivate and content type applied at done, whose count is the serial a
commit must carry.  The keyboard is grabbed at every activate and
released at every deactivate, because sway hands keys to the grab holder
without asking whether the input method is active, and a grab held while
inactive would take every key in the session.  Keys come as evdev codes,
go through xkb and the Compose table the other frontends already share,
and reach the engine as an ipckeysym and a modifier mask; the grab's
modifiers go on to the virtual keyboard as well, since wlroots derives no
state from a virtual keyboard's own keys.  A key the engine does not eat
goes back as a key, not as text, and whatever is still down is released
when the context goes.  A password or a PIN purpose never reaches the
engine at all.

No popup yet: the X11 one still owns drawc, and with no Keycaret from us
it follows the pointer.

Checked by hand under headless sway 1.12 with a GTK3 entry driven by
wtype: ascii passes through, Ctrl+s selects Korean, rk shows the preedit
and Enter commits 가 and lets the Return on, Ctrl+c arrives with its
modifier, focus moving between two clients re-grabs and keeps typing, a
password entry types literally, a second strans says so and stops, and
WAYLAND_DISPLAY without a compositor falls back to XIM.

f6477cb97d test: the unit build takes the dialect the daemon is built with 
9c compiles with -std=gnu11 and UNIT_CFLAGS overrode that with -std=c99,
so the tests built the daemon's own sources under a dialect the daemon
never sees.  Under it glibc hides lstat, and server_test.c reaches
<sys/stat.h> before srv.c pulls in u.h -- it must, since thread.h
defines recv as chanrecv and the socket recv it calls has to be declared
first.  So make all was green while make check would not compile.
HOST_CFLAGS keeps -std=c99: those are host programs with no Plan 9
headers.

ef7fb627c6 compose: one Compose table for the XIM and IBus frontends 
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.

cd637be4ca ibus: die where startup fails; print the Plan 9 way; drop what said nothing 
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.

5faefd9a87 dict: lookups take a trie; a prefix search is its own function; no self-key rule 
dictlookup took a Lang for two reasons that were not its business: to
know whether to walk below the key (the emoji dictionary) and to drop a
candidate equal to the key except there.  No dictionary lists its key
among its candidates — the rule was left from a first version that put
the reading first itself — so it goes, and the walk is dictprefix(),
called by the emoji search alone.

3d862bdc0d engine: keys outside a map pass on like any other; one candidate query; the caret rides on every key 
Space and non-ASCII keys with a Korean or Telex syllable pending were
committed as text along with the syllable, while '.', ',' and digits
committed the syllable and passed on: one path for both now, through the
language's own trans, which commits and passes on.  Japanese Space is
its own key already.

dictqjp() knows which languages have candidates; its two callers no
longer choose between it and clearkouho().  Every request carries its
owner's caret as the frontend knows it, so a Keypress copies it whether
valid or not, and the XIM frontend need not send a Keycaret to say that
its spot went away.

半角/全角, ひらがな/カタカナ, 変換, and 無変換 committed the reading and did
nothing, like any function key.  They now stand for what a Japanese
keyboard means by them: toggling Japanese and English, switching kana
modes, converting (or turning Japanese on), and turning it off; the
Korean keys became a switch of the same shape.  The keypad's arrows
and page keys, with NumLock off, fold onto the plain ones as its Enter

Ctrl+H took the pending syllable as the query, but the keys typed after

Ctrl+H, k showed ㄱㅏ.  transstr now composes from a pending text, so

The three jamo index tables and their -1 macros were the cho, jung, and

Every Japanese IME converts a reading to Katakana on demand; strans made
the user switch to the Katakana mode and type again.  Space now adds
the reading in Katakana after the dictionary candidates, so a loanword
the dictionary lacks converts with one Space and Enter, and 漢字 users
still get 漢字 first.

0 committed the reading only while candidates showed; without them it
typed a 0 as well.  It now commits any Japanese reading, the counterpart
of 1-9 picking candidates, as the README always said.

A sixth of kanji.dict is SKK's okuri-ari entries, keyed by a stem and
the letter of the okurigana that follows it — かk: 書 描 掛 —, and no
reading ever ends in a letter, so かく offered 確 and 各 but never 書く,
and no verb or adjective could be converted at all.  Now every split of a
complete reading is tried, longest stem first, with the okurigana put
back: かく adds 書く and 描く after the exact candidates, よむ gives
読む, あかい 赤い, おおきい 大きい, いった 言った, かいた 書いた.  A stem

abff5ed122 emoji: search the dictionary by prefix in the engine, not in the data 
mkemoji wrote a row for every prefix of every alias, so that a query
matched as it was typed; the trie is a prefix index already, and with a
real emoji list those rows would be four times the aliases themselves.
Now emoji.dict has one row per alias, trienode() names a key's node, and
dictlookup walks the entries at and below it, the key's own first, up to
Maxkouho.  Trie children are appended rather than pushed, so the walk
keeps the file's order and a bare digit still picks the superscript or
subscript it always did.

The hand-written symbol rows move to symbol.src; emoji.src is left to
the emoji.  mkemoji reads both by default, or the files it is given.

Both are now Mozc's default table in full, kata.map in Katakana, so that
they agree (kata.map alone had di → ディ and a lone v).  With Mozc, wi

n' is a row now, not a case in transjp.  A row whose value is っ keeps
its consonant pending only when it is a doubled consonant or tch: xtu

e8519b4e06 engine: no candidate is chosen until the user moves to one; Space converts 
A complete Japanese reading showed its candidates with the first row
highlighted, yet Enter committed the reading unless the user had moved
to a candidate: the highlight lied.  Now sel is -1 while nothing is
chosen, and it alone says what Enter commits; candidatechosen goes.

Every key that ends a composition — Enter, Tab, a language switch, a
special key, a modifier chord, typing on — now commits the chosen
candidate through one flush; before, only Enter and Tab did, and Ctrl+S
after choosing 漢字 committed かんじ.

Space in a Japanese mode is the conversion key, as in every other
Japanese IME: it steps through the candidates (Shift+Space backwards,
both wrapping) and commits a reading that has none, without typing a
space.  Backspace and Escape on a chosen candidate go back to the
reading first.  Tab in a search wraps through the same cyclekouho.

reset() no longer forgets the caret: a chosen candidate confirmed by
typing on would otherwise redraw the next reading at the pointer.

rejectold forked and re-execed the test binary with --reject-address
just to call dbus_connection_open_private once against the crashed
daemon's abstract address, then waited on the helper, drained its
stderr pipe and checked its exit status. An abstract socket with no
listener refuses the connection immediately, so the call cannot block
and needs no separate process.

Open the address in-process and require a null connection with the
D-Bus error set, freeing the error afterwards. This drops the helper
process, its stderr capture, the Test.helper fields and the argv
dispatch in main. killdaemon stays; the daemons still need it.

7220286ab5 test: share one daemon and D-Bus harness across live tests 
Six live tests carried private copies of the same daemon harness: the
private XDG_RUNTIME_DIR, the fork/exec with captured stderr, the
readiness waits, the SIGTERM and SIGKILL paths, the IBus address file
reader, the socket connect, and the IPC probe. Three of them also
carried the same libdbus helpers.

Extract one implementation into tests/live.c and, so that the binaries
that do not link dbus-1 keep not linking it, the D-Bus half into
tests/livebus.c. Both are compiled into each binary the way ../ipc.c
already is. gtk_live_test keeps its own fake-server harness and only
takes fail, nowms and leftms; xim_live_test keeps its own Xvfb and
process-group daemon spawn, which must inherit DISPLAY, and takes the
temporary directory, timing and cleanup halves.

The copies had drifted; the harness keeps the stricter behaviour.

  - nowms reports a broken clock (-1) instead of pretending it read
    zero, and leftms turns that into an expired deadline, so a loop
    ends in a timeout failure rather than spinning. livesetup checks
    the clock once up front, as daemon_restart_test did.
  - Timeouts compare with <= 0, not == 0.
  - readuntil keeps the three-way result (complete, peer closed, error)
    from ipc_live_test and daemon_restart_test rather than folding
    peer closure into ECONNRESET.
  - The daemon's stdout and stderr are both captured, and a failing
    setenv is reported, for every daemon; daemon_failure_test captured
    stderr only and said nothing about setenv.
  - The child keeps daemon_restart_test's careful redirect that also
    works when the pipe lands on fd 1 or 2.
  - parseaddress requires a positive declared PID.
  - killdaemon reports ECHILD after SIGKILL as a failure; one copy
    accepted it. It now reaps with a blocking waitpid, which SIGKILL
    guarantees will return, instead of daemon_restart_test's polled
    wait with its own timeout diagnostic.
  - stopdaemon tolerates ESRCH on SIGTERM, a benign race two copies
    reported as an error.
  - liveclean removes the socket and address files and then rmdirs
    each directory, reporting leftovers, rather than deleting the
    temporary root recursively.
  - ibus_live_test now waits for the IPC socket and the address file
    by polling, dropping its inotify variant; it asserted only the
    address file before.

loop, and test_util reimplemented the shown preedit; the engine exports
impre(Im*, Str*) and transstr() instead, so a change to composition
rules is one edit.

849bf1278b popup: one text drawing call; drop what the draw thread never reaches 
font.c exported three wrappers for one function, and the fit == -1 mode
existed only for the tests; textdraw() takes fit and colour. win.c
tested the empty picture in the thread and again in winshow, interned
two atoms by hand next to getatom(), kept a consumer-side drain that the
producer's already guarantees never finds anything, zeroed ten globals
before returning from the only thread that read them, and re-checked
sizes that resizebacking had just established. The page marker is laid
out once and drawn from the layout instead of being recomputed.

eaf31da0d1 ibus: one reply path, no ceremony around calls that cannot fail 
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.

c2baa47026 fix(xim): follow keyboard layout changes 
kinit() sets up the XKB extension, after which the server stops sending
core MappingNotify to this client, so the refresh branch never fired and
strans kept its startup keymap; setxkbmap after launch left every XIM
key resolved against the old layout. Select XKB NewKeyboardNotify and
MapNotify (with the map parts, or MapNotify is never delivered) and
rebuild the keymap on those events instead.

a70cfc42e3 xim: drop what no client uses; poll for owner loss like IBus 
XIM text always went out through imdkit's COMPOUND_TEXT converter,
which already wraps every UTF-8 string in ESC%G; the UTF8_STRING
negotiation, the per-client encoding list, ximtext.c's fallback and its
wrapper never changed a byte on the wire. The spot location is honoured
for every style now (GTK's XIM module sends it with PreeditCallbacks)
and an unset focus window means the client window, as the spec says,
so those clients get the popup at the caret. readattrs/place kept four
transient fields to pass values between them; ximclose tore down state
right before die(); the OOM passthrough context was a third policy for
one small calloc where emalloc dies like everything else. Both frontends
now poll for engine-owner loss only while a preedit shows instead of
XIM waking on a pipe the engine had to know about; ibus stops waking
five times a second when idle. keymeaningful() is the engine's own
predicate. The standalone xim_test moved into the unit suite, so
xim/Makefile is gone.

9080bb833c engine: trim the key dispatch 
mapget and maplookup were one trie probe with two predicates; mapmatch
returns the match kind and mapget is its exact case. movedelta is a
switch. searchkey's modifier test was unreachable behind transition's,
searchlang's Alt/Super test behind both callers' earlier returns, and
picksearch's range check behind numberedkouho. Korean key folding runs
once at the top of transition. commit() on an empty preedit is a no-op,
so the Ctrl branch and startsearch lose their haspre guards and repeated
commit/reset pairs. Ctrl+language inside a search now commits the shown
query as it does elsewhere instead of dropping it. Language ids are
documented as the Ctrl codes they are; Im parameters no longer shadow
the file's Im.

68869e2589 engine: redraw when the picture changes, not when the state might have 
Every key copied the whole Im and Search rune by rune, compared them
after the transition, and combined the answer with 'eaten', a commit
count that is always zero, and a force flag for caret and owner changes,
while redraw() kept a separate 'visible' bit to know when to send an
empty popup. redraw() now compares the snapshot with the last one sent
and treats two empty popups as equal, so imhandlekey just ends in
redraw(). keystroke() was only a test entry point and moves there.

a557fb114a engine: one trans contract for every language 
Japanese was never dispatched through the Lang table: dotrans and
transstr both special-cased it into transjp, which edited Im in place
and wrote commits through a side argument, while transko popped and
cleared a pre that every caller overwrote anyway, and Vietnamese kept
its key history in dotrans. Emit now carries the new raw state next to
the new pre; transjp, transko and transvi are pure functions of (Im,
key), and dotrans and transstr have a single path. Vietnamese history
bookkeeping lives in vi.c, where the full-history flush no longer
resets the caret as a side effect; istone was toneidx() >= 0.

abaea77248 engine: look dictionaries up synchronously 
The dictionary thread ran in imthread's own proc, so a lookup could
only start once the engine blocked, and it was a trie probe anyway; the
emoji and Hanja searches already called dictlookup directly. The
request/result channels, sequence numbers, staleness checks and the
second draw per Japanese key are gone; dictqjp fills the candidates
in place. Emit.dict and Lang.dictq only ever triggered lookups for
Vietnamese, which has no dictionary. dictlookup(Lang*, key, out, max)
returns the count. The Hanja lookup no longer pre-checks for a single
syllable; a reading either has an entry or it does not.

ebcec3af6b fix(engine): send clients the composed Telex text, not the keys 
For Vietnamese the preedit is the map key ('as', 'oong'); only the popup
and the commit path looked it up. Clients with inline preedit therefore
showed 'as' while Enter committed 'á'. impre() now maps once for every
reader, and snapshot() no longer maps a second time.

c7718ece52 data: one trie for maps and dictionaries, one loader 
The hash map served a single exact-match lookup that the trie already
answers, at the price of a second container, a second file loader with
its own drift, and a Str-to-UTF-8 conversion on every chain probe. The
files are small (kanji.dict is 7.5k lines), so the trie holds both.
trieopen validates keys and each space-separated value word against Str
and reports path:line; trielookup takes the Str every caller holds and
treats a nil trie as an unloaded map; trienew/trieput exist for tests.
The overflow guards on growth, Trie.root (always 0) and the per-language
init loop written twice are gone.

eb0f88f764 ipc: strip machinery no peer uses; keep client state in one Keyreq 
ipc.c: an AF_UNIX nonblocking connect completes at once or fails with
EAGAIN, so the EINPROGRESS/poll/SO_ERROR path and the fcntl juggling
were dead; the deadline plumbing checked a clock that cannot fail and
re-tested the deadline before every transfer although only waitfd
blocks; readfield's truncation and discard loop served the unit test,
since every caller owns char[Ipcfieldmax+1]; NULL-argument checks on
in-tree encoders are gone (peer validation stays). The primary key frame
is Ipckey, not 'legacy'; ipckeysym names the keysym mapping.

srv.c: the per-connection capability and caret already lived in the
persistent Keyreq; the mirror locals and 'negotiated' flag guarded a
protocol rule no client relied on. proccreate never fails in libthread.

gtk: focus-out no longer round-trips a reset before closing the socket
that releases the engine; the caret dedup compares the packed frame;
srvconnect's preedit no-ops and the insimple flag are gone.

43b469f70b ipc: share one keysym and modifier mapping across frontends 
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.

66ea2892f8 bench, docs: let the client detect readiness; say what Enter commits 
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

-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.

c1971c8096 fix(popup): accept depth-24 roots regardless of colormap precision 
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.

# strans
strans is a small, single-user input method for Korean, Japanese, English,
and emoji on X11 and Wayland. It provides one engine shared by XIM, GTK 3,
IBus, and Wayland input-method-v2 frontends. The existing Vietnamese Telex
mode remains available for compatibility, but is not an actively developed
language mode.
emoji and symbols, with Vietnamese Telex as a compatibility mode. One
engine serves four frontends: `zwp_input_method_v2` on Wayland — sway and
any other compositor that offers it — IBus, which GTK 4 and Qt use, XIM,
and a GTK 3 module.
## Input behavior
## Modes
English is direct passthrough. Korean uses 2-beolsik composition. Japanese
Hiragana keeps the complete kana reading until it is committed, so `kanji`
forms `かんじ` and offers whole-reading candidates such as `漢字` and `幹事`.
An apostrophe resolves an ambiguous `n` without forwarding the apostrophe:
for example, `n'ya` forms `んや`. Katakana is direct Katakana composition
and does not perform Kanji dictionary conversion.
| Key | Mode |
| --- | --- |
| `Ctrl+S` | Korean Hangul (2-beolsik) |
| `Ctrl+N` | Japanese Hiragana, converting to Kanji |
| `Ctrl+K` | Japanese Katakana |
| `Ctrl+T` | English |
| `Ctrl+V` | Vietnamese Telex |
| `Ctrl+E` | Emoji and symbol search |
| `Ctrl+H` | One-shot Hanja and symbol search |
A Japanese composition is committed by Enter, candidate selection, a real
input boundary, or an explicit mode change. Backspace first removes pending
romaji, then accumulated kana. The Japanese modes support doubled consonants
and combinations such as `nya`, `nnya`, and `matcha`.
Only a plain `Ctrl` chord is a strans key: with `Shift`, `Alt` or `Super`
held it commits what is pending and goes to the application, so
`Ctrl+Shift+V` still pastes. `Backspace`, `Enter`, `Tab`, `Esc` and the
arrow and page keys do the same under `Ctrl`, so `Ctrl+Backspace` still
deletes a word. The mode switched to — `한`, `あ`, `ア`, `ă`, `A` — shows
in the popup until the next key. A Korean keyboard's 한/영 and 한자 keys
stand for `Ctrl+S`/`Ctrl+T` and `Ctrl+H`; a Japanese one's 半角/全角,
ひらがな/カタカナ, 変換 and 無変換 for the kana modes, `Space` and English.
Modes are selected with Ctrl and one letter:
## Composing
```text
Ctrl+N Japanese Hiragana and Kanji conversion
Ctrl+K Japanese Katakana
Ctrl+S Korean Hangul
Ctrl+T English passthrough
Ctrl+V Vietnamese Telex compatibility mode
Ctrl+E Emoji and symbol search
Ctrl+P Toggle popup preedit
```
Japanese composes a whole reading and then offers its Kanji with none
chosen. `Space` and `Tab` step through the candidates and wrap (`Shift`
reverses), the reading in Katakana last, so a word the dictionary lacks
converts with one `Space`; `Up`/`Down` and `PageUp`/`PageDown` move without
wrapping. A chosen candidate takes the reading's place in the preedit, so
it stands where it will land, and `Enter` commits it, or the reading, as
`0` and typing on always do. Once a candidate is chosen `1`-`9` take that
row of the page shown; before that the digits type. `Backspace` deletes
the last kana shown, and romaji that made no kana stays as typed until it
is mended; `Esc` cancels the reading, and on a chosen candidate both go
back to it. The dictionary keys verbs and adjectives by stem and
okurigana, so `kaku` offers かく's readings and then 書く and its kin —
typing the okurigana with `Shift`, as SKK does, `kaKu`, asks for that
split first. Katakana mode does not convert, so there `Space` and `Tab`
commit the reading and go on to the application.
While candidates are visible, Up and Down move the selection, Enter accepts
the selected candidate, and an unmodified `1`-`9` selects the corresponding
visible row. Tab cycles emoji search results. `0` commits an unconverted
language reading. Escape cancels the current composition. Ctrl, Alt, or
Super combined with a number does not select a candidate.
Korean composes one syllable at a time. `Enter`, `Tab`, `Esc` and any key
that is not a jamo commit the syllable and go on to the application, so
`Esc` still leaves insert mode. Two lone consonants join into the compound
final they make (rt → ㄳ), and a vowel typed before its consonant is
reordered under it (kr → 가), as in libhangul.
Emoji search is temporary and returns to the previous mode. Queries may use
English aliases or the active language's input rules, including Japanese
`egao` becoming `えがお` or `エガオ`:
A search takes the keys until `Enter`, `Space` or `1`-`9` picks a result or
`Esc` cancels, then returns to the previous mode. Emoji matches the typed
keys, and what they spell in the current mode, against a prefix of every
emoji's CLDR name and keywords in English, Korean and Japanese, and against
ASCII aliases such as `->` and `<=`. `Ctrl+H` takes the syllable being
composed as its query and composes on from it, converting a word as well as
a syllable — 한자 gives 漢字, 대한민국 gives 大韓民國 — and `Esc` gives the
syllable back. A word is committed a syllable at a time, so the reading
also reaches back into the text the application already holds, as far as
the dictionary knows the whole of it: type 한자 and then `Ctrl+H` and the
query is 한자, not 자, and picking 漢字 takes the 한 back. `Backspace`
gives that reach back before it deletes what was typed, so 상 written
with 태 typed answers 狀態, and one `Backspace` answers 態 for the
syllable alone. A reading is also the start of the longer words it
begins, whose conversions follow its own, so 대한 answers 大寒 first and
大韓民國 further down. A lone consonant is a reading too, and answers
with the symbol table a Korean keyboard's 한자 key has always offered:
ㅁ gives ※ ○ △ ㈜, ㄴ the brackets 「」『』, ㄹ the units ℃ ㎏ ℓ, ㅇ the
circled numbers ①②③.
```text
Ctrl+E → smile → Enter → 😀
```
Reaching back needs the application to hand over the text around its
cursor and to take some of it away again. The Wayland input method, IBus
and the GTK 3 module all can; XIM has no such request, so there the
reading is what is still being composed and nothing else, and an IBus
client that reads a key's effects only after the call returns is not
asked for its text either, since a deletion could not be ordered before
the commit.
Dead keys and Compose sequences are composed by strans itself for the
Wayland, XIM and IBus frontends, from `XCOMPOSEFILE` or the locale; the
GTK 3 module leaves them to GtkIMContextSimple.
## Preedit and candidates
| Frontend | Preedit | Candidates | Reaches back |
| --- | --- | --- | --- |
| Wayland input method | inline in the client | popup | yes |
| GTK 3 and IBus | inline in the client | popup | yes |
| XIM PreeditCallbacks | inline through XIM callbacks | popup | no |
| XIM PreeditPosition, PreeditNothing | popup | popup | no |
On Wayland the popup is a surface the compositor places at the text cursor,
flipping it above the line when there is no room below. Elsewhere it is an
X11 window, placed from the XIM spot or from the GTK caret, and XIM text
travels as `COMPOUND_TEXT`. Either way `GDK_SCALE` sizes it for HiDPI
displays.
## Build and test
The supported build uses Docker so host and container toolchains are not
mixed. Only Docker and Make are needed on the host:
```sh
git submodule update --init
make docker-image
make docker-build
make docker-check
```
`docker-image` creates the Arch Linux dependency image, `docker-build`
compiles the runtime components, and `docker-check` runs the map verifiers and
test suites. Docker targets force their own compilation, so newer host
objects cannot be reused. `docker` is a convenience alias for the image and
build steps.
The resulting runtime artifacts are:
```text
strans daemon, IBus and Wayland frontends
xim/strans-xim XIM frontend
gtk/im-strans.so GTK 3 frontend
```
Use `make docker-check TESTARGS=hangul` to filter the C unit tests. A native
build is still possible with the dependencies and Plan 9 setup recorded in
`Dockerfile`; use `make all`, `make check`, and `make bench` inside that
environment.
After editing `map/emoji.src`, regenerate and verify its dictionary with:
That leaves `strans`, the daemon, and `gtk/im-strans.so`, the GTK 3 module.
Tests come in three tiers:
```sh
make check # generated-map validation and unit tests
make check-live # one IBus, GTK, XIM and IPC daemon smoke each
make check-stress # randomized, capacity, collision, failure and restart
```
`make docker-check` runs all three in the container, and
`make docker-valgrind` the unit suite under Valgrind; rerun
`make docker-image` after changing `Dockerfile`. `UNITARGS=hangul` filters
the unit suite alone, not the other tiers.
A native build wants a C toolchain, Make, pkg-config and Plan 9 port, plus
development files for D-Bus, XCB and xcb-imdkit, Wayland and
`wayland-scanner`, xkbcommon, Pango and Cairo, and GTK 3; the tests also
want Xvfb, Python 3 and fonts covering Latin, CJK and emoji.
[`Dockerfile`](Dockerfile) names the exact packages.
## Run
```sh
./run.sh # restart the daemon in the background
./strans map # or run it in the foreground
```
`./strans DIR` reads `hira.map`, `kata.map`, `telex.map`, `kanji.dict`,
`emoji.dict` and `hanja.dict` from `DIR` at runtime; nothing but the GTK
module is installed. A service supervisor wants the session's
`XDG_RUNTIME_DIR` and its `WAYLAND_DISPLAY` or `DISPLAY`: the GTK module
finds the daemon at `$XDG_RUNTIME_DIR/strans.sock`, else
`/tmp/strans.UID`, and IBus clients through the address file libibus
expects under `~/.config/ibus/bus/`, which strans writes as `ibus-daemon`
would.
strans shows one popup per session, so it picks a frontend at startup: a
compositor offering `zwp_input_method_v2` gets the Wayland frontend, and
then neither XIM nor the X11 popup runs; every other session gets XIM. The
IBus endpoint and the GTK 3 module are served in both.
On Wayland, then, set none of the variables below. GTK, Qt and Firefox
speak text-input-v3 themselves — GTK 4 binds it with `GTK_IM_MODULE` unset
— and setting these is what pushes them off the path that works: such a
client still composes inline but shows no candidates, because the popup
belongs to the Wayland frontend. Chromium is beyond help either way, since
it asks for `text-input-v1`, which wlroots does not implement.
```sh
export XMODIFIERS=@im=strans # XIM
doas make -C gtk install # GTK 3 module
export GTK_IM_MODULE=strans
GLFW_IM_MODULE=ibus kitty # IBus client example
```
strans provides its own IBus endpoint, so `ibus-daemon` and fcitx are not
needed. Building the GTK module wants GTK development files; installing
one built elsewhere does not. The install target takes `GTK_MODULE_DIR`
when set, else asks GTK where its modules live; `doas make -C gtk uninstall`
removes it. With neither `WAYLAND_DISPLAY` nor `DISPLAY` the daemon still
serves IBus and its socket, but nothing draws a popup.
## Dictionary data
After changing an input source, regenerate and verify:
```sh
python3 map/mktelex.py >map/telex.map
map/mkemoji >map/emoji.dict
map/mkhanja >map/hanja.dict
make verify-map
```
Japanese dictionary regeneration and verification are documented in
[`map/README`](map/README). The converter output is deterministic UTF-8,
tab-separated data consumable by the runtime dictionary reader.
[`map/README`](map/README) says where the emoji, Hanja and Japanese data
comes from.
## Run and install
## Benchmark
Start the daemon with the installed map and font directories:
`make bench` builds `bench/bench`. With the daemon stopped, `./bench.sh`
starts one, warms it up and records the workload with Linux `perf` into
`bench/perf.data`.
```sh
./strans map font &
```
## Licensing
The IPC socket is placed at `$XDG_RUNTIME_DIR/strans.sock` when
`XDG_RUNTIME_DIR` is an absolute path. Otherwise strans uses the per-user
fallback `/tmp/strans.<uid>`. A second daemon will not replace a live
daemon's socket.
For XIM applications:
```sh
./xim/strans-xim &
export XMODIFIERS=@im=strans
xterm
```
For GTK 3 applications, install the module built by Docker. Installation
needs the GTK 3 runtime, but not its development package:
```sh
doas make -C gtk install
```
`LIBDIR` defaults to `/usr/lib` and may be overridden for another system.
Normal `DESTDIR` semantics are supported, and a staged install does not update
the host GTK module cache:
```sh
make -C gtk install DESTDIR="$pkgdir"
```
For IBus clients such as kitty:
```sh
GLFW_IM_MODULE=ibus kitty
```
Wayland needs no environment variable. Start `strans` after a compositor
that supports input-method-v2. Neither ibus-daemon nor fcitx is required.
Starting without `DISPLAY` is supported: the optional X popup is disabled,
while input processing and non-X frontends continue to run.
## Ownership and rendering constraints
There is one global composition, not one independent engine per frontend
context. The first meaningful key from a new context resets the previous
composition and transfers ownership. Reset, focus loss, context destruction,
and disconnect affect the engine only when they come from its active owner;
stale events cannot clear a newer owner's preedit.
The popup is an optional X window, including when the active frontend is
Wayland. It uses deterministic font fallback and fixed-width rune cells;
U+FE0E and U+FE0F variation selectors use zero cells. It does not perform
OpenType shaping, color-emoji rendering, or general grapheme clustering, and
there is no native Wayland popup renderer. Multi-rune emoji are committed
intact but are drawn as their constituent rune cells under this boundary. A
supplied caret rectangle is used when available, with the pointer as fallback.
The X renderer accepts only a 24-depth, 32-bpp TrueColor root format and
disables itself cleanly on other visuals.
## Data, third-party code, and licensing
Data and third-party provenance is recorded in
[`docs/PROVENANCE.md`](docs/PROVENANCE.md), with font-specific details in
[`font/PROVENANCE`](font/PROVENANCE). The historical SKK-derived Kanji
dictionary is distributed under GPL version 2 or later; its license text is
in [`LICENSES/GPL-2.0-or-later.txt`](LICENSES/GPL-2.0-or-later.txt).
The repository does not currently declare a license for the strans project
source as a whole. The licenses of bundled data, fonts, generated protocol
code, and third-party components do not by themselves license the original
strans source.
Third-party notices are in [`LICENSES`](LICENSES). The repository declares
no license for the strans source as a whole.

# Data and third-party provenance
This file records what can be established from repository contents and
history. It does not assign a license to original strans source code.
## Input maps and dictionaries
`map/hira.map`, `map/kata.map`, and the original map data entered the history
in commit `cc157c0b3c33506d1cbf5bd251ddc6a9ca909081`, whose subject says the
maps came from 9front. That commit does not identify a 9front revision or
carry a separate data license. `map/telex.map` is generated by
`map/mktelex.py`; Vietnamese behavior is retained for compatibility.
`map/emoji.dict` is generated deterministically from the repository-maintained
`map/emoji.src` by `map/mkemoji`. No external dataset is required.
`map/kanji.dict` identifies itself as SKK Medium dictionary version 8.1,
May 24, 1995, rearranged for Plan 9 ktrans by Kenji Okamoto on February 17,
2000. Its header names its copyright holders and grants GPL version 2 or
later. The complete GPL version 2 text is in
`LICENSES/GPL-2.0-or-later.txt`; the dictionary header supplies the
"or later" option. `map/README` records the exact repository history,
repairs made to this copy, and the reproducible procedure for importing a
new SKK revision.
## Fonts
The popup bundles Noto Sans, Japanese-region Noto Sans Mono CJK, and Noto
Emoji. Exact checksums, versions or source revisions, download locations
where known, fallback order, and license-file names are recorded in
`font/PROVENANCE`. The corresponding OFL 1.1 and Apache 2.0 texts are kept
beside the fonts.
## stb_truetype
`stb_truetype.h` is Sean Barrett's stb_truetype version 1.26, dated
August 28, 2021 in its header. Its exact repository checksum is:
```text
ecd30b05e0dd4fea3a13c26810dd9e1992dc379049482c393d5a19e6b5090aab
```
The file was present in the repository's first commit,
`dcd1147638f908eca7e4b7616815e215022cc99d`. No upstream commit or download
URL was recorded. Its complete dual MIT/Public Domain terms are retained at
the end of the header.
## Generated Wayland protocol code
The four checked-in Wayland protocol C/header files were added in commit
`7629ec5fe8976812655c9d12b447a62abc8bb671`:
- `input-method-unstable-v2-client-protocol.h`
- `input-method-unstable-v2-protocol.c`
- `virtual-keyboard-unstable-v1-client-protocol.h`
- `virtual-keyboard-unstable-v1-protocol.c`
Their embedded notices identify the protocols as input-method-unstable-v2
and virtual-keyboard-unstable-v1 and include the applicable MIT-style license
terms. The input-method files report generation by wayland-scanner 1.21.0;
the virtual-keyboard files report wayland-scanner 1.23.1. The source XML
files and their upstream repository revisions were not committed or recorded
in history, so these generated files cannot honestly be regenerated
byte-for-byte from repository artifacts. Do not edit them manually. A
future regeneration should commit the source XML or record its immutable
upstream revision and the scanner command/version.
## Git submodules
`cutest` is pinned by the repository as the unit-test framework. XIM uses
the system xcb-imdkit and xcb-util libraries at build time; those system
libraries are not bundled by this repository.

institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply to
any document created using the fonts or their derivatives.

* This protocol allows applications to act as input methods for compositors.
*
* An input method context is used to manage the state of the input method.
*
* Text strings are UTF-8 encoded, their indices and lengths are in bytes.
*
* This document adheres to the RFC 2119 when using words like "must",
* "should", "may", etc.
*

# Japanese dictionary data
# Dictionary data
## Korean Hanja and symbol data
`hanja.src` and `mssymbol.src` are the tracked, reviewable sources for what
the Hanja search converts. Every data row is a result, a tab, and its
Hangul reading. A Hanja reads as a syllable or a word; a symbol reads as
the lone consonant a Korean keyboard's 한자 key offers it under:
```
漢 한
漢字 한자
※ ㅁ
```
`mkhanja` validates that contract and groups the rows of both sources by
their reading to produce the runtime dictionary. The two keyspaces do not
meet: a reading is either syllables or one jamo. Candidate order follows
source order. The sources keep all retained pairs for review; the
generated dictionary stores the first 128 candidates per reading because
that is the engine's lookup limit.
The sources are derived from libhangul release tag `libhangul-0.2.0`. The
annotated tag object is `20afc38922e3595ee3ed5b186f2ea05afe663763`, its
peeled commit is `41c702f5d3581325b646ef6249f1f641b0427ae0`, and
`data/hanja/hanja.txt` and `data/hanja/mssymbol.txt` have blob IDs
`199cfd70c4b306257ac2e018714a1285f7cf0ed3` and
`31c4e63d74293b6a759d4a2005cd1e7333746631`. Import and regenerate them
from the repository root with:
```sh

map/libhangul2hanja upstream >map/mssymbol.src

`libhangul2hanja` keeps a syllable reading only when its value is Hanja the
popup can draw: U+3400–U+4DBF, U+4E00–U+9FFF, or U+F900–U+FAFF. Thus mixed
values and supplementary-plane ideographs are omitted. It keeps a jamo
reading, U+3131–U+314E, only when its value is one rune the popup can draw
and a candidate row can carry — so `mssymbol.txt`'s ideographic space and
soft hyphen are omitted, leaving 985 of its 987 rows, and a Hanja under a
jamo reading is omitted as noise. The import preserves each upstream
license header and row order. The retained data is BSD 3-Clause licensed
by Choe Hwanjin; the complete text is in
`LICENSES/BSD-3-Clause-libhangul-hanja.txt`.
## Emoji and symbol data
`symbol.src` is hand-written: a symbol, a tab, and its ASCII aliases, kept
so that a bare `1`-`9` picks the matching superscript or subscript from a
`^` or `_` prefix search. `emoji.src` is generated: every fully-qualified
emoji of Unicode's `emoji-test.txt` except the skin-tone variants, with
its CLDR names and keywords in English, Korean, and Japanese. `mkemoji`
folds the aliases, adds each Japanese one in the other kana so a query
typed in either mode finds it, and writes one row per alias to
`emoji.dict`; the engine searches that dictionary by prefix, so the rows
carry no prefixes.
The sources are Emoji 17.0 and CLDR 48.2.0. Regenerate them from the
repository root with:
```sh

<description summary="Protocol for creating input methods">
This protocol allows applications to act as input methods for compositors.
An input method context is used to manage the state of the input method.
Text strings are UTF-8 encoded, their indices and lengths are in bytes.
This document adheres to the RFC 2119 when using words like "must",
"should", "may", etc.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible changes
may be added together with the corresponding interface version bump.
Backward incompatible changes are done by bumping the version number in
the protocol and interface names and resetting the interface version.
Once the protocol is to be declared stable, the 'z' prefix and the
version number in the protocol and interface names are removed and the
interface version number is reset.

<interface name="zwp_input_method_v2" version="1">
<description summary="input method">
An input method object allows for clients to compose text.
The objects connects the client to a text input in an application, and
lets the client to serve as an input method for a seat.
The zwp_input_method_v2 object can occupy two distinct states: active and
inactive. In the active state, the object is associated to and
communicates with a text input. In the inactive state, there is no
associated text input, and the only communication is with the compositor.
Initially, the input method is in the inactive state.
Requests issued in the inactive state must be accepted by the compositor.
Because of the serial mechanism, and the state reset on activate event,
they will not have any effect on the state of the next text input.
There must be no more than one input method object per seat.

<description summary="input method has been requested">
Notification that a text input focused on this seat requested the input
method to be activated.
This event serves the purpose of providing the compositor with an
active input method.
This event resets all state associated with previous
surrounding_text, text_change_cause, and content_type events, as well
as the state associated with set_preedit_string, commit_string, and
delete_surrounding_text requests. In addition, it marks the
zwp_input_method_v2 object as active, and makes any existing
zwp_input_popup_surface_v2 objects visible.
The surrounding_text, and content_type events must follow before the
next done event if the text input supports the respective
functionality.
State set with this event is double-buffered. It will get applied on
the next zwp_input_method_v2.done event, and stay valid until changed.

Updates the surrounding plain text around the cursor, excluding the
preedit text.
If any preedit text is present, it is replaced with the cursor for the
purpose of this event.
The argument text is a buffer containing the surrounding text, and must
include the cursor position, and the complete selection. It should
contain additional characters before and after these. There is a
maximum length of wayland messages, so text can not be longer than 4000
bytes.
cursor is the byte offset of the cursor within the text buffer.
anchor is the byte offset of the selection anchor within the text
buffer. If there is no selected text, anchor must be the same as
cursor.
If this event does not arrive before the first done event, the input
method may assume that the text input does not support this
functionality and ignore following surrounding_text events.
Values set with this event are double-buffered. They will get applied
and set to initial values on the next zwp_input_method_v2.done
event.
The initial state for affected fields is empty, meaning that the text
input does not support sending surrounding text. If the empty values
get applied, subsequent attempts to change them may have no effect.

Tells the input method why the text surrounding the cursor changed.
Whenever the client detects an external change in text, cursor, or
anchor position, it must issue this request to the compositor. This
request is intended to give the input method a chance to update the
preedit text in an appropriate way, e.g. by removing it when the user
starts typing with a keyboard.
cause describes the source of the change.

Text input state (content purpose, content hint, surrounding text, and
change cause) is conceptually double-buffered within an input method
context.
Events modify the pending state, as opposed to the current state in use
by the input method. A done event atomically applies all pending state,
replacing the current state. After done, the new pending state is as
documented for each related request.

The argument text is a buffer containing the string to insert. There is
a maximum length of wayland messages, so text can not be longer than
4000 bytes.

with the pending state.
The connected text input is expected to proceed by evaluating the
changes in the following order:
1. Replace existing preedit string with the cursor.
2. Delete requested surrounding text.
3. Insert commit string with the cursor at its end.
4. Calculate surrounding text to send.
5. Insert new preedit text in cursor position.
6. Place cursor inside preedit text.
The serial number reflects the last state of the zwp_input_method_v2
object known to the client. The value of the serial argument must be
equal to the number of done events already issued by that object. When
the compositor receives a commit request with a serial different than
the number of past done events, it must proceed as normal, except it

This event is sent as soon as the zwp_input_method_keyboard_grab_v2

client before any key press event.
Negative values for either rate or delay are illegal. A rate of zero
will disable any repeating (regardless of the value of delay).
This event can be sent later on as well with a new value if necessary,
so clients should continue listening for the event past the creation
of zwp_input_method_keyboard_grab_v2.
