# Fix: message being sent leaks into another chat's compose/draft, and erases what is typed there
Branch: `nd/fix-inflight-send-writes-other-chat-compose` (off `origin/stable`)
Date: 2026-07-25
PR: #7308
Line references are against `origin/stable` at `8dc387cb5`, with this fix
applied. Android and desktop only
(`multiplatform/.../views/chat/ComposeView.kt`); iOS has the same defect
but is not addressed here.
## Problem
Two reported symptoms, one cause. Both need a send that is still in
flight when the chat is switched (slow network, large file, or the send
just hanging with the progress circle showing):
1. **The message ends up in another chat's draft.** Reply to a message
(or just type), press send, switch to another chat while it is
sending: the text *and the reply context* appear in that chat's input,
and leaving it saves them as that chat's draft. No forwarding
involved.
2. **A late send erases what you typed.** Press send, the progress circle
keeps spinning, switch to another chat and back, type a new message —
when the original send finally succeeds, the newly typed message is
erased.
## Cause
The compose state is shared, and the send outlives the chat:
- `ChatView.kt:134` — one `MutableState<ComposeState>` per `ChatView`
instance, `rememberSaveable` with no keys, reused for every chat that
the view displays.
- `Utils.kt:43-46``withLongRunningApi` launches on
`CoroutineScope(Dispatchers.Default)`, a standalone scope with no tie
to the composition or to the chat, and `sendMessage`
(`ComposeView.kt:972-976`) uses it. Leaving the chat never cancels an
in-flight send.
Two writes then act on the wrong chat:
- **On the chat switch** — `ComposeView.kt:1343-1347`: the `cs.inProgress`
branch used to keep the message in the shared compose state
(`composeState.value = cs.copy(inProgress = false, progressByTimeout = false)`)
and only cleared the *previous* chat's saved draft. The text and the
quote were therefore sitting in the input of the chat opened next, and
`ComposeView.kt:1348-1358` (`!cs.empty`) then saved them as *that*
chat's draft on the next switch. Symptom 1.
- **When the send completes** — `ComposeView.kt:943-968`, running in the
detached coroutine after the switch: `clearState(live)` on success, or
`composeState.value = lastFailed` on failure, where `lastFailed =
cs.copy(inProgress = false, preview = preview)`
(`ComposeView.kt:729`) **keeps `contextItem`, i.e. the reply**. On
success this wipes whatever is in the input now — including a message
typed after coming back (symptom 2); on failure it dumps the old
message into whichever chat is open (symptom 1 again).
The same function was already inconsistent about which chat it acts on:
its draft bookkeeping (`clearCurrentDraft()`, and the forwarding
condition) uses the **captured** `chat` — the chat the message was
composed in — while its `composeState` writes hit whatever chat is
displayed at that moment.
## Fix
Two changes, both in `ComposeView.kt`.
**1. Do not keep the message being sent in the shared compose state**
(`ComposeView.kt:1343-1347`). On switching away with a send in flight the
compose state is cleared, so nothing leaks into the chat opened next:
```kotlin
} else if (cs.inProgress) {
clearPrevDraft(prevChatId)
// the message being sent must not be kept in the compose state, it is shared with the chat opened next;
// if it fails to send it is restored in this chat or saved as its draft
clearState()
}
```
`clearState()` is used rather than assigning an empty `ComposeState` so that
the link preview state is reset too (`pendingLinkUrl` still points at the
sent message's link, and its fetch would otherwise set a preview on the
input of the chat opened next), and so that the attachment size limit is
carried over the same way as everywhere else.
In-flight content is deliberately **not** saved as a draft here: the
message has been submitted and will most likely be sent, and a draft is
for messages that are not sent yet.
`clearState()` alone would leave the chat opened next with an empty input
even when it has a draft: this branch, like the live message one above it,
returns before the branch that loads a draft
(`chatModel.draftChatId.value == draftChatId(chatModel.chatId.value, chatScope)`),
so that draft was never shown - and, being still in the slot but not in
any compose state, it was then dropped by `clearPrevDraft` on the next
chat switch. It is loaded here instead. This is not the one-slot
limitation below: nothing else is competing for the slot, the draft is
simply lost.
**2. Only touch the compose state if it still holds the message that was
sent** (`ComposeView.kt:936-968`):
```kotlin
withContext(Dispatchers.Main) {
val chatIsOpen = chatModel.chatId.value == chat.id
val liveSend = live || cs.liveMessage != null
val sentMessageInCompose = chatIsOpen && (liveSend || composeState.value.inProgress)
if (sentMessageInCompose) {
if (lastFailed == null) {
clearState(live)
} else {
composeState.value = lastFailed
}
}
val draft = chatModel.draft.value
if (wasForwarding && chatModel.draftChatId.value == draftChatId(chat.chatInfo.id, chatScope) && forwardingFromChatId != chat.chatInfo.id && draft != null) {
if (sentMessageInCompose) composeState.value = draft
} else {
clearCurrentDraft()
if (!sentMessageInCompose && lastFailed != null) {
// the message was not sent, so it is restored in the chat it was composed in, or kept as its draft if another chat is open
if (chatIsOpen && composeState.value.empty) {
composeState.value = lastFailed
} else if (saveLastDraft) {
chatModel.draft.value = lastFailed
chatModel.draftChatId.value = draftChatId(chat.id, chatScope)
}
}
}
}
```
Both the checks and the changes run on `Dispatchers.Main` (the block has
no suspension points), so they cannot be interleaved with the user
switching chats or typing - `KeyChangeEffect`, which does change 1, runs
there too.
`inProgress` is the marker that the compose state is still the submitted
message: it is set by `sending()` (`ComposeView.kt:596-598`), preserved by
`copy` while sending (the only other write during a send is
`progressByTimeout` at `ComposeView.kt:1610-1617`), reset when switching
away (change 1), and never set by typing a new message. So a chat switch
*or* newly typed text both make the guard false.
A **failed** send is different from an in-flight one - the message was not
sent, so it is an unsent message. It is put back into the input if that
chat is open and nothing else is being composed there, and kept as that
chat's draft otherwise, so it never appears in another chat (see the
limitations below for when it is still dropped). Staying in the chat is
unaffected: the guard is true there
and the failed message is restored into the input as before, keeping
"preserving long message when failed to send" (`e61babdc8`) working.
Deliberately unchanged:
- The condition of the forwarding branch. Gating the whole branch would
send a forward that completed after the user left to `clearCurrentDraft()`
instead, **deleting** the destination chat's draft that the branch
exists to preserve - only the compose write inside it is gated.
- Live message sends (`live`, or `cs.liveMessage != null` for the send
that finalises a live message when leaving the chat, `ComposeView.kt:1338-1342`),
as long as their chat is the one open. They never call `sending()`, so a
guard based on `inProgress` would change their behaviour: failed live
sends would stop restoring and would write a draft on every failing
keystroke send. That is why `liveSend` is an alternative to `inProgress`
inside the guard, and why it is excluded from the restore/draft branch -
not gating it there would produce exactly that draft-per-keystroke.
What they are **not** exempt from is `chatIsOpen`. An earlier revision
had `live || cs.liveMessage != null` outside it, which holds only while
a live message is always sent to the chat that is open. #7323 removes
that: the live message committed by a chat switch is sent to the chat it
was composed in, while this view already shows another one, so an
unguarded clause here would clear *that* chat's compose state - the leak
this fix exists to prevent. Standalone this changes nothing except a
live send that completes after its chat was left, which now leaves the
opened chat alone. `sendMessageAsync` reads `composeState` inside the
coroutine (`ComposeView.kt:684`), so that branch cannot clear the state
itself without racing the send; #7323 adds the `composed` parameter that
makes the captured state explicit.
**3. The same check where the flag is shared** (`ComposeView.kt:600-602`
and the three senders that connect a prepared chat). They call the same
`sending()`, so an unguarded `clearState()` or `inProgress` reset from
one of them corrupts the state of a send started in the chat opened next.
## Behaviour after the fix
| situation | before | after |
| --- | --- | --- |
| send, stay in chat, succeeds | input cleared | input cleared (unchanged) |
| send, stay in chat, fails | message restored in input | message restored in input (unchanged) |
| send, switch chats, succeeds | message left in the other chat's input, saved as its draft | other chat untouched |
| send, switch chats, fails | message dumped into the other chat's input | message restored in the chat it was composed in, or kept as its draft |
| send hangs, switch away and back, type, then it succeeds | typed message erased | typed message kept |
| forward send, still in destination chat | destination chat's draft restored | unchanged |
| live message sent on leaving the chat | compose state cleared by the send | unchanged |
## Limitations
Kept deliberately, to not grow the change:
- A message that failed to send is dropped, rather than kept, when the
"Message draft" privacy setting is off, when the destination chat of a
failed forward already has a draft (its own draft is preserved
instead), and when the single draft slot is later taken by another
chat - drafts are one global slot, so the last write wins.
- The three senders that connect a prepared chat share the same
`sending()` flag, so they use the same check (`ComposeView.kt:604-616`,
`618-640`, `659-685`). Without it a connect completing after the chat
was switched would clear `inProgress` for a send started in the chat
opened next, and that sent message would then stay in the input. They
have no failed-message restore, so their typed message is dropped when
the chat is switched instead of being carried into the next chat.
- Typing in the same chat while its own send is in flight is still
cleared when the send completes: `inProgress` is preserved by `copy`,
so the guard stays true. Unchanged from before, and different from the
reported symptom, which needs the chat to be switched.
## Verification
- `./gradlew :common:compileKotlinDesktop` — passes.
- Manual (needs a slow or failing send — e.g. airplane mode, or a large
file). On desktop any chat switch exercises it; on Android only an
in-place switch does (member info → open chat), because leaving to the
chat list destroys the view:
1. Reply + type in A, send, switch to B while sending. B's input must
stay empty; leaving B must not create a draft in B. If the send
failed, A must hold the message (with the reply) as its draft.
2. Send in A with the network off so the circle keeps spinning, switch
to B and back to A, type a new message, restore the network. The
typed message must survive the old send completing.
3. Regression: ordinary send in A (input clears), failed send while
staying in A (message comes back in the input), forward into a chat
that has a draft (draft restored after sending).
Rebased onto the scope-aware draft ids introduced by #7309: the draft
written here for a message that failed to send uses
`draftChatId(chat.id, chatScope)`, like every other draft write.

# Fix "Save passphrase in settings" toggle unreachable on desktop
## Symptom
On 7.0 desktop (reproduced on the Linux AppImage and on Windows), in
Chat data → Database passphrase & export → Database passphrase, the
"Save passphrase in settings" toggle cannot be switched off. The reporter sees
the switch sitting slightly past the right edge of the section card. Because the
setting stays on, the passphrase remains stored in `settings.properties` and the
app never prompts for it on start — on desktop that file holds the passphrase in
clear text, since `Cryptor.desktop.kt` is an identity implementation.
This is distinct from the case where the switch is *rendered disabled*
(`DatabaseEncryptionView.kt:127`, `enabled = (!initialRandomDBPassphrase && !progressIndicator) || migration`),
which is intended behaviour for a database still using the initial random
passphrase. The reports here are from users who set their own passphrase, so
`initialRandomDBPassphrase == false` and the switch is enabled — just not
reachable.
## Root cause
1. `SavePassphraseSetting` is hand-rolled in both platform actuals
(`DatabaseEncryptionView.desktop.kt:43-53`, `.android.kt:43-53`) and is the
only toggle row in the app whose label carries no `weight`:
```kotlin
Text(stringResource(MR.strings.save_passphrase_in_settings), Modifier.padding(end = 24.dp))
Spacer(Modifier.fillMaxWidth().weight(1f))
DefaultSwitch(checked = useKeychain, onCheckedChange = onCheckedChange, enabled = enabled)
```
`Row` measures unweighted children first against the full available width, then
divides what is left among weighted ones. A label that does not comfortably fit
consumes the remainder, the weighted `Spacer` collapses to zero, and
`DefaultSwitch` is placed past the row's right edge.
2. Every other toggle row goes through `SettingsActionItemWithContent`
(`SettingsView.kt:380`), which gives the label `Modifier.weight(1f)`. There the
label truncates and the trailing control keeps its size and position, so the
same string length is harmless.
3. Before #6777 this row had enough slack and no clipping. `SectionView` was a
plain `Column` with no horizontal inset, and `SectionItemView` used
`DEFAULT_PADDING` (20.dp) per side — 348.dp of content width on the desktop
start pane (`DEFAULT_START_MODAL_WIDTH` = 388.dp). Any overflow still drew and
still received pointer events.
4. #6777 introduced `LocalCardScreen` / `CardColumnLayout` (`Section.kt`), which
wraps section content in `Modifier.padding(horizontal = CARD_PADDING /* 18.dp */)`
… `.clip(SectionCardShape)`, and switches `itemHPadding` from `DEFAULT_PADDING`
to `CARD_PADDING`. `DatabaseEncryptionView` is opened with `cardScreen = true`
(`DatabaseView.kt:235`), so its row content width drops 348.dp → **316.dp**.
5. `Modifier.clip` clips pointer input as well as drawing. The displaced switch is
therefore both cut off visually and unhittable — the toggle stops working rather
than merely looking wrong.
Budget arithmetic on the desktop start pane: fixed cost in the row is ~96.dp
(24 icon + 8 spacer + 24 label end-padding + ~40 switch), leaving ~220.dp for a
27-character label at 16.sp, which needs ~215.dp in English. Borderline at 100%
font scale and over budget as soon as the label is longer — a longer localization,
or a larger font size, since the label scales with `fontSizeSqrtMultiplier` while
`CARD_PADDING` does not.
The widths above are derived from the layout constants, not measured against a
running client; the reporter's observation that the switch sits slightly past the
card edge is what confirms the row overflows in practice.
## Fix
Move the weight onto the label and drop the weighted spacer, in both actuals:
```kotlin
Text(stringResource(MR.strings.save_passphrase_in_settings), Modifier.weight(1f).padding(end = 24.dp))
DefaultSwitch(checked = useKeychain, onCheckedChange = onCheckedChange, enabled = enabled)
```
The label now truncates instead of displacing the switch, matching what
`SettingsActionItemWithContent` does for every other toggle row.
The spacer has to go: leaving both the label and the spacer weighted would split
the remaining space between them and starve the label instead, which trades one
layout bug for another.
## Why this fix and not alternatives
- **Widening the card or shrinking `CARD_PADDING`** would buy back the ~32.dp lost
in #6777, but only until the next longer localization or font-size step. The row
would stay the one place in the app where a long label can push a control out of
reach.
- **Removing `clip` from `CardColumnLayout`** would restore clickability of
overflowing content, but the clip is what gives section cards their rounded
corners; dropping it would regress the design and leave the switch drawn outside
its card.
- **Shortening the string** is a translation-wide problem, not a fix, and does not
help at larger font sizes.
## Impact
- Desktop and Android only. Both actuals carry the identical defect; Android's row
is in fact narrower still (~288.dp on a 360.dp-wide screen), so it is affected at
least as much — it simply has not been reported.
- iOS is unaffected: `DatabaseEncryptionView.swift` uses a SwiftUI `Toggle` inside
`settingsRow`, where the label truncates and the toggle cannot be displaced. The
`initialRandomDBPassphrase` disabled-state logic is the same on iOS
(`DatabaseEncryptionView.swift:80`) and is unchanged by this fix.
- Users already stuck in the bad state have `StoreDBPassphrase=true` in
`settings.properties` with the passphrase stored alongside it. After this fix
they can turn the setting off in the UI, which removes the stored passphrase via
`removePassphraseFromKeyChain` and restores the prompt on start.
- No behaviour change beyond the row layout: no logic, preference, or string was
touched.
## Verification
- `bash ~/build/linux.sh` on this branch: cold `dist-newstyle`, `libsimplex.so`
rebuilt from master's sources, `:common:compileKotlinDesktop` executed,
`BUILD SUCCESSFUL`, AppImage produced.
- `bash ~/build/android.sh` on this branch: `BUILD SUCCESSFUL`, arm64-v8a debug APK
produced (native libs are the prebuilt ones, so this exercises the Kotlin change
only).
- Not done: the rendered row has not been checked in a running client. Worth
confirming at a raised font size and in a locale with a longer label, which is
the case that made the overflow visible in the first place.
