feat(ios): several Linux systems at once, and the UI around them - #1329

Conversation
Checked every section against the tree. Three things had drifted: - The entity tables (#1322) went past what the "Hive → SQLite" plan said would stay key-value, and drift came back for the DDL. Both are recorded, with the superseded reasoning kept and marked rather than rewritten. - `sandbox_import.dart`'s `app.db` special case was listed as dead code. It is not: both sites now key on `SqliteDb.fileName`, and the `-shm` skip matches by exact name so a user's own file still comes across. - "Android / Linux / Windows unverified" still holds, and for a sharper reason than the entry gave: `build.yml` only runs on a `v*` tag, and the last such run predates `hook/build.dart`, so no CI run has exercised the hook path on any platform.
… SIGUSR1 `Activity<T>.request` is synchronous and makes a blocking XPC round trip to `liveactivitiesd`. Running it straight from the MethodChannel handler put that wait on the main thread, so the UI froze until the daemon answered — most visibly on the first activity of a run, which is what starting Alpine requests. LiveActivityManager becomes an actor. The blocking request hops to a dedicated serial queue rather than parking a cooperative-pool thread, and `current` is no longer read and written by every detached Task with nothing ordering them. The duplicated localization and ContentState construction collapse into one `contentState(from:)`. All three MethodChannel cases now answer from inside the Task instead of after starting it: TermSessionManager's drain loop awaits each call, and that await is what orders successive updates. Separately, the iOS Linux engine interrupts its guest threads with SIGUSR1 — on signal delivery, on task exit, and on every timer tick — and lldb stops the whole process on each one by default, which reads as the app hanging the moment Alpine starts. The scheme now points at a checked-in lldbinit that sources Flutter's generated one (required, and what the tooling's migration checks for) and passes SIGUSR1/SIGTTIN/SIGPIPE through, as iSH's own ish-lldb.lldb does.
Its pigeon output carries no `package` declaration, so `Wakelock.kt` reaches the generated types with `import IsEnabledMessage` — an import from the root package, which Kotlin 2.2 rejects. Release builds failed in `:wakelock_plus:compileReleaseKotlin`. Neither end moves: every published version from 1.3.2 to 1.7.0 is written that way, and Flutter's gradle plugin refuses a KGP below 2.2.20, so there is nothing to upgrade or downgrade to. Scoped to that one module so the app's own Kotlin is not held back.
Both painted `colorScheme.surface`, which `ThemeDataX.toAmoled` does not override — it replaces `scaffoldBackgroundColor`, the dialog, sheet and card slots, and leaves the scheme alone. So under an AMOLED theme this was the one tab that stayed Material grey, rail included, while every page around it went black. The tab now shows the `Scaffold`'s background like the terminal and file tabs do, and the rail is transparent so it shows whatever it sits in — that background in a column, the sheet's own in a sheet.
The shell's `Scaffold` held an empty box the height of the status bar to push the tabs clear of it. A page pushed inside a tab lives in `body`, under that box, so the strip stayed put while the page animated below it and entering or leaving a page read as two pieces moving separately. The box is gone and the inset lands on the tab's own content, inside `NestedNavigator.rootBuilder`. That placement is the point: a pushed page is a sibling route, outside the `SafeArea`, so it reaches the top of the window. Wrapping the navigator instead would inset the pushed page too and put the seam back. Not in each tab either — three of them put a `Scaffold` inside a pane splitter, and the splitter's divider is above any app bar that could have spent the inset. Doing it per tab left that divider crossing the status bar in the terminal tab. The bottom bar keeps its seam and is left alone: it is chrome the tabs share, and a page opened in a tab is meant to leave it in place.
TODOS.md: - Android is off the unverified list. `dart run fl_build -p android` produces the three split-per-abi packages, and the arm64 one runs on an Android 16 phone and an emulator. `RustLib.init()` is before `runApp` and throws on an FRB mismatch, so a clean start is evidence the hook built a loadable `aarch64-linux-android` dylib. Linux and Windows are still unverified, and CI has still never run the hook path. - The Hive to SQLite migration is verified on a device, not just in `flutter test`: the v1466 fixture through the 1491 build gives the same counts the unit test asserts, and the released 1466 APK upgrades in place. Two things worth keeping: do not launch the old build first, it rewrites the boxes; and `store.db` shares the Hive key, so a planted key makes the result readable off the device. - The wakelock_plus workaround, with the condition for deleting it. CLAUDE.md: `flutter clean` deletes the iOS Linux engine, which is built out of tree under `build/`. Nothing in the checkout looks different afterwards and the next iOS build fails with three missing-`.a` linker lines that name no cause.
bcc7b1a pointed the Runner scheme's customLLDBInitFile at a checked-in ios/Flutter/lldbinit that sourced Flutter's generated one with `--relative-to-command-file`. That flag only resolves when the commands are being sourced from a file, which is not how `flutter run` feeds lldb, and `--stop-on-error false` swallowed the failure. So flutter_lldb_helper.py never loaded, the NOTIFY_DEBUGGER_ABOUT_RX_PAGES breakpoint was never set, and the Dart VM could not get an executable page: debug builds stopped at the launch screen with nothing printed. Profile mode on the same device launched fine, which is what put the fault in the debug-only lldb path rather than in the Live Activity change from the same commit. That change stays — profile exercises it too, through the `stopLiveActivity` that `_initApp` awaits before `runApp`. Passing SIGUSR1 through for the ish engine is still worth having, but not at the cost of the scheme. It belongs in ~/.lldbinit or an Xcode breakpoint action, neither of which is shared.
`flutter run` installs a stop hook that backtraces every thread and detaches the moment the process stops, and iSH raises SIGUSR1 constantly, so the two together end a debug session on the first guest signal. In debug mode detaching drops the breakpoint the Dart VM needs for an executable page, so the app goes with it — and the `bt all` that comes attached to the report is the hook's output, not a request. Also records that the scheme's customLLDBInitFile is the wrong place to fix this: `flutter run` on Xcode >= 26 never reads it.
Android refuses `link()` inside an app's own data directory, and `-0`
does not help: it makes the guest believe it is root while the uid the
kernel checks is still the app's. A package whose tar carries hard links
fails on exactly those entries and on nothing else — `apk add go` reports
`Permission denied` for `usr/bin/gcc-{ar,nm,ranlib}` and `usr/bin/ld.gold`
and leaves a gcc with no drivers, while the other 31 packages install.
termux/proot carries the extension for this, which is why the build uses
that fork rather than upstream; it was simply never passed. A hard link
becomes a symlink, which these tools are indifferent to — each dispatches
on `argv[0]`.
The rootfs test asserted a package install, but the package was curl,
which has no hard links, so it said nothing about this. It now creates one
directly: cheap next to the 357 MB `apk add go` pulls to reach the entries
that fail, and it is the capability rather than one package's use of it.
Verified both ways on an emulator, which refuses `link()` the same way a
phone does — without the flag the new assertion fails with an empty read.
…no imp for `application:didDiscardSceneSessions:` is an optional UIApplicationDelegate method and FlutterAppDelegate does not implement it, so the `super` call raised NSInvalidArgumentException and terminated the app. It fires when the user closes the app from the switcher, which is why it took a reinstall over a still-listed session to show up. `applicationWillTerminate:` is the opposite case — FlutterAppDelegate does implement it, and it is how registered plugins hear the app is going away — and that one was missing its `super`. Both checked with `otool -oV Flutter`: the first selector appears only in the protocol's name table, the second has an imp.
Opening a session on the terminal or file tab moved the target's name into the running section, where it gets a close button — and the row went from 35pt to 58pt, because a Material control takes a 48pt tap target regardless of the constraints set on it. fl_lib now overrides that on the row itself, so the Agent's history panel is fixed too.
`IosRootfs.read` answered `String.fromCharCodes`, which reads each byte as one code unit, and the terminal encoded that back to UTF-8 — so every byte of a multi-byte character became two. `中` (E4 B8 AD) reached xterm as six bytes and drew as `ä¸`. The tty echoes what is typed through the same path, so it was visible while typing, before any command ran. Both directions are bytes now. The terminal keeps UTF-8 decoding state across chunks, which is more than this layer can do when each read is a separate call and a character can straddle two of them. `IshExec` does need text, and uses a chunked decoder for the same reason — it holds an incomplete tail back until the rest arrives. `_SinkOf` exists because `dart:convert`'s own sinks either buffer to `close` or want a `StringSink`. Not verified on a device yet.
`sbm_ish_boot` ran init as `while :; do /bin/sh; done`. Init has no tty and no stdin — a pty is what `sbm_ish_open` gives each session, not something init gets — so every one of those interactive shells read EOF and exited at once and the loop started another. A fork/exec storm, inside an interpreter, for as long as the machine was up. It made the whole app slow from the moment Alpine was opened, and closing the last terminal did not stop it, because the machine deliberately stays up. It also starved hot restart badly enough to look like a hang. Init only has to exist and never exit, so it sleeps instead, wrapped in a loop so a signal cutting the sleep short cannot end it. Verified on device: the app is no longer slow in debug with a terminal open, hot restart works again, and the guest's highest pid stops climbing. Two Dart costs on the same path, both paid per frame per session: - `IosRootfs.read` malloc'd and freed an 8 KB buffer on every poll, including while the shell sat at a prompt. Allocated once and kept. - The poll ran at 16ms for the life of the session, which outlives the page — it kept running with the terminal off screen and the app on another tab. It now relaxes to 120ms after eight empty reads and snaps back on the first byte. - `IosRootfs.isAvailable` called across FFI on every read, and `tab_add.dart` reads it three times per build. The answer is fixed when the app is built.
"Edit virtual keys" is a row that opens a page; the verb belonged to the page, not to the name of the thing. "Known host keys" names the keys when what the page manages is the hosts they belong to. "Full screen mode" carries a word that says nothing the other two do not. Reworded in each of the fifteen locales rather than in English with the rest left to follow — `Modifier les touches virtuelles` → `Touches virtuelles`, `Полноэкранный режим` → `Полный экран`, `已信任的主机密钥` → `已信任的主机`. The `editVirtKeys` key no longer matches its value. Renaming it means touching every locale and every reference, so it is left as it is.
Four things, all in the settings page. **A group's own settings are General, not Settings.** `app`, `server` and `terminal` each carried a leaf named "Settings", inside a page called Settings — three rows with the same name, and the word said nothing the parent had not. `general` is new in fl_lib, translated in all fifteen locales. **Backup is two pages.** Keeping data somewhere else and bringing data in are different questions that shared a page because both move data. The page was already built as two lists under two headings, so the split is a `BackupSection` and no new layout. The standalone `/backup` route still shows both, side by side, with its own headings: the DMG notice opens it directly and there is no menu around it to say which half you are looking at. **Three orderings are one page with tabs.** "Server order", "detail page widget order" and "sequence" read alike as three menu rows — you had to open one to find out which list it held. Side by side as tabs each is named by what the other two are not. The three pages are unchanged and still routable; the server settings page still links straight at the last of them, where three tabs would answer a question nobody asked. Its duplicate rows for the other two are gone. **Seams.** Two `VerticalDivider`s used Material's default colour, which is drawn for a light background and reads as a bright line on a dark one — they sit at the same corners as the one `AdaptivePanes` draws through `Hairline`. And the content routes were transparent: the pages under them are `embedded` and drop their own `Scaffold`, so during a transition each route showed the one it was covering.
lollipopkit/ShellBox#1 landed on main as 17de9b99, carrying the two upstream commits that apply to this fork — the /proc/pid/mem show op and the warning sweep, the latter with sigusr1_handler's signature corrected back to (int) because kernel/init.c installs it as a sa_handler. Its static-libs release is published, so scripts/ensure-ish-libs.sh has something to fetch for this revision.
…s revision The three .a files the Runner target links were only ever produced by running scripts/build-ish-ios.sh by hand, and nothing in the build said so: ios/Flutter/Ish.xcconfig hands their paths to the linker through OTHER_LDFLAGS, and when they are absent the build stops with three 'No such file or directory' lines that name the files and not the reason. Two ordinary ways to get there — building for the device and then running the simulator, since each target has its own build-<arch> directory, and 'flutter clean', which removes build/ and takes them with it while leaving a checkout that looks untouched. A new Runner build phase runs ahead of Flutter's own and fetches the release the fork publishes for the submodule's checked-out HEAD, falling back to a local build when there is no such release — the case while the engine's own source is being worked on. The gitlink is this repository's only statement about which revision of the engine it builds against, so binding the download to it is what keeps the libraries and the headers from drifting apart; the sha they were fetched for is recorded beside them, because 'git submodule update --remote' otherwise leaves the previous revision's libraries where they are still found. CI opts in the same way a development machine does, by writing IshLocal.xcconfig, rather than by moving Ish.xcconfig's SBM_ISH=0 default. It installs no toolchain: iOS CI now links the engine, and if the download finds no release the gitlink points at an unpublished revision and the build says exactly that.
The guest was Alpine in the settings' own words and in every constant
behind them. Nothing could be pointed elsewhere, which is how a device on
a network that cannot reach dl-cdn.alpinelinux.org ends up with a Linux
it cannot install packages into and no setting that says so.
Settings, under Terminal > Linux — named for Linux and not for the
distribution, since which one is installed is now a thing that changes:
- the distribution, from LinuxDistro
- its mirror, kept per distribution so switching away and back does not
drop what was typed. Empty restores the distribution's own default
- the resolvers written to /etc/resolv.conf, which are not per
distribution: that is the network the device is on
Saving either of the last two rewrites the file in a system already on
disk. Both are seeded at install and never again, so without that a
mirror changed afterwards would only take effect on the next install —
which on iOS means deleting everything apk ever put there.
LinuxDistro carries what differs between distributions: label, version,
branch, default mirror, digest, the tarball URL's shape, and the path and
format of the file the package manager reads. Its switches are
exhaustive, so a second entry is a case here and an arm in each of them.
The digest stays pinned in code while the mirror is a setting: a mirror
decides where the bytes come from and never which bytes are accepted.
What is on disk is now recorded rather than assumed. The marker holds the
distribution and the version, so switching knows what it replaces and an
update offer knows what the version on disk is a version of. Both older
formats — a bare version, and an empty file — read as Alpine, which is
what wrote them.
iOS asked whether a system was installed with bin/busybox and
etc/alpine-release, which are Alpine's. Replacing them with bin/sh and
etc/os-release needed a second change: Alpine's /bin/sh is an absolute
symlink to /bin/busybox, a path inside the guest, so File.exists()
answers false for a tree that is perfectly fine. Every existing install
would have read as absent and been offered for reinstall, taking
everything in it. looksUnpacked() does not follow links, and a test locks
that.
Which shell a session gets was hardcoded twice — `/bin/sh` in `sbm_ish_open` and again in `AndroidRootfs.enterCmd`. Alpine ships no `chsh`, which is the usual way to change it and also a red herring: the guest has no `login` and nothing in it reads `/etc/passwd`, so the shell is this app's choice and no other. A setting is the whole answer. `sbm_ish_open` takes it as a parameter now, NULL or empty meaning `/bin/sh`. A shell it cannot exec falls back to `/bin/sh` and says so to syslog, rather than handing back a terminal that dies on sight — the setting is checked before it is stored, so reaching that fallback means the guest changed underneath it. Interactive sessions only. A one-shot command keeps `/bin/sh` on both platforms, because the app and the Agent write POSIX and parse what comes back: fish is not a POSIX shell, and a status script or an `&&` run through the user's choice would fail in ways that read as the remote host being broken. The path is checked for shape and then for being there, against the tree that is actually installed. Neither failure is visible afterwards — the engine answers ENOENT from inside `sbm_ish_open`, and nothing puts that on screen. Existence is checked without following links, since Alpine's shells are links to busybox by a guest-absolute path that does not resolve host-side. Also records, in TODOS.md, what was established about multiple kernels and about background execution: iSH's kernel state is file-scope global so a second instance means a fork that diverges structurally, real isolation on iOS needs a second process and an App Store app has none, and the only sanctioned way to keep running in the background is BGContinuedProcessingTask on iOS 26 — which the verification iPad, on 18.7.8, cannot use.
One kernel, many roots — which is what a container is, and as much as iOS allows: an App Store app cannot fork, so a second *kernel* would need a second process it has no way to get, and iSH keeps its state in file-scope globals besides. So the systems share a PID space, a network and a pty numbering, and can see each other through /proc. That is the deal, and it is written down in the header rather than implied. The machine's root is now a container of trees, one subdirectory per system, and nothing runs at that level. sbm_ish_attach mounts one system's /proc, /dev, /dev/pts and /dev/shm — idempotent, so opening a terminal in a system that is already up costs a strcmp. sbm_ish_open takes which one to run in and points the task at it before anything opens a path, since attach_stdio names /dev/pts/N and that has to mean this system's devpts. Safe because construct_task gives every task its own fs_info (kernel/init.c:107) rather than sharing init's, so the root of one session is not the root of another. Init lives inside a system rather than at the container root, which holds no /bin/sh to start it with, nor the loader that shell names. A profile is a directory plus the marker in it, and nothing else: no table, no setting listing what exists. So one deleted from disk cannot linger in a list, and a list cannot promise a tree that is not there. The id is that directory's name, generated — keying it by distribution was the first attempt and it made two Alpines side by side impossible, which is the case this exists for. The distribution is a field of the marker, the label is another and is the user's. Selecting is not switching. Nothing is deleted, sessions already running stay where they are, and the settings page is a list with add, rename, update and delete rather than a picker that replaces what is there.
Brings in the audit branch (ShellBox #2): the fakefs error contract, the poll and epoll registration lifetimes, the AF_LOCAL handshake no longer putting a struct fd * on the wire, and unit tests for the leaf logic each of those changed. libs-cdab02e23c0eb897d0bd89ce6c8aa04c3d8e9d8c is published with all three archives, so ensure-ish-libs.sh fetches rather than building. The previous revision's libraries in build/ are replaced rather than reused — that is what the .ish-libs-sha stamp is for, and a gitlink bump is exactly the case it was added to catch.
…reads Alpine ships no `chsh` — it is in `shadow`, which a minirootfs does not carry — and installing the real one would not have helped: it edits /etc/passwd, and nothing in this guest reads that. There is no `login` here. So the stand-in at /usr/local/bin/chsh writes the file that does decide, and is a shell script. /usr/local/bin comes before /usr/bin in the PATH the engine sets, so it also shadows the real one for anyone who installs `shadow` later — the outcome to want, since that one edits a file with no readers and reports success. A chsh already there that is not ours is left alone: overwriting a package's file would have apk reporting a modified system. The shell moves out of the app's settings and into the guest, at etc/serverbox/shell. One file is the answer for both sides, so there is no rule about which store wins. It falls out per system, which is right: a shell is a path to a file inside one tree, and /usr/bin/fish being installed in one says nothing about another. Read when a terminal opens rather than from anything cached, so a chsh run a second ago is in force. The script is tested by running it. It ships to users, is edited by nobody who can try it where it runs, and a syntax error there surfaces as "chsh does something odd" and nothing else — test/chsh_script_test.dart is `sh` on the host reading the same bytes, over every branch including the ones that must refuse without writing.
…once The engine has held several systems since the container root landed; the terminal tab could not say which one it wanted. LocalSource carries a profile id now, and that is the only thing telling two of these tabs apart — same device, same kind of source — so it has to be in the id that a saved set stores and a backup carries. Null there means "whichever is selected", resolved when the shell opens rather than when the tab is made. That is what a set saved before this existed says, and what it meant: there was one system, and the one system there is is the selected one. A set naming a profile this device has not got is skipped like an unknown server — restoring a backup onto another device is exactly how that happens. Opening asks which, once there is more than one. Opening "the selected one" would have made the second unreachable from the terminal tab, and they run at once, so it is a choice and not a switch. Deleting closes the tabs of that system and leaves the others, which is the point of them being separate. Both backends take the id: on iOS it reaches sbm_ish_open, on Android it picks proot's -r. proot is a host process per session, so nothing had to be coordinated there beyond passing it down.
The narrow settings pane read its insets from a context above the Scaffold, where padding.top is still the status bar the app bar already covers. It handed that back to the page, whose own SafeArea applied it a second time, so every embedded page began a status bar below the top — and the home indicator was counted twice at the foot. The floating level tabs now sit over the content rather than on a strip taken out of it: the bar is translucent and blurs what passes behind, and the room a list needs to bring its last row clear of it arrives as scroll padding (context.padBottom) instead of as a shorter page. Its own way back is gone; the title bar has one, and two on a screen was the same move twice. The shadow goes back to an elevation — one soft shadow at 16% read over a full page and vanished over the bare background of a short one. The SSH page's background moves behind the whole Scaffold, so the virtual keys are drawn on it too. They painted the terminal theme's background, which is not what the terminal is drawn on — TerminalView is given backgroundOpacity: 0 — and stood out as a strip of another colour. atLeastOneTab goes with them: nothing has used it since the home tabs page started reporting serverTabRequired instead.
…tion lollipopkit/ShellBox#3. Two places in the engine answered in the machine's terms to a task that cannot name them, and both surface the moment a session is rooted at a subtree — which is what this app started doing when it began holding several Linux systems under one machine root. An absolute symlink target restarted from the machine root, so Alpine's `/bin/sh -> /bin/busybox` resolved to a `/bin` the task cannot see; `getcwd` reported `/alpine` for what was that task's own `/`. Without the first, nothing in a profile could exec at all. Both are identity for a task rooted at the machine's own root, so nothing on the single-root path this app shipped before changes.
Measured rather than inferred: a backspace held 4.5s produced one KeyDownEvent and one KeyUpEvent and nothing between. The bursts that look like repeat are discrete presses — every Down has a matching Up ~80ms later, which auto-repeat does not do. So `KeyRepeatEvent` never arrives on this path and the half of xterm's guard that tests for it is dead code on iOS. The fix has to be a timer the app runs itself; where it goes is a trade-off the note states.
The tab strip gave each tab a fixed 60-90pt on a phone, which is about six characters once the close button and the insets have taken their share, and a third session already overflowed a row spending 43% of its width on a leading button, three dividers and the actions. It replaces that with the session on screen named in full, its position among the rest, and a sheet holding all of them — see the fl_lib commit. Both tabs feed it what a row can now say that a tab could not: an address for a terminal, a path for a browser. The wrapper both pages put it in is what the Scaffold measures, so it is told the height rather than left on kToolbarHeight. That default was already giving the old 48pt strip 56. The virtual keys get a walkthrough instead of the paragraph in a dialog that nobody reads. It floats over the terminal and stops where the keys begin, so the row it is describing stays lit while the page behind it dims, and the keys outside the step's group fade with it. Three kinds and not seventeen keys: which of them type, which move the cursor, and which leave the terminal altogether. Holding a key is what keeps paying off after that — VirtKeyX.help has only ever been visible in the settings list, and now it is on the key itself. snippet and tmux grew one so that all six shortcuts answer. Two things worth naming: - Every restored tab lays out, not only the one landed on, so the walkthrough waits for its own page to be the visible one. Without that it is spent on whichever tab the PageView built first and the user meets a flag already set. - The server list's own title button rippled across the whole row. Flexible hands down loose constraints and the Row inside it was left at MainAxisSize.max, so it took every point the tags had not claimed.
It was the app's name beside a badge, with a history button and a new-conversation button on the right — three ways of saying "Agent" and none of saying which conversation you were in. Now it is the line the terminal and file tabs carry: which one this is of how many, its whole title, and a chevron. Tapping it opens the conversation list, which is where switching, renaming, deleting and starting one already live. So both buttons go: the history one was a second way to that same sheet, and the plus was a third thing on a row that never said what it was about. Refused while a tool is running, for the reason the list's own rows are — switching away leaves the execution appending to whichever conversation is active by then. Beside the history column there is nothing to open, that column being the list, so the line is a label there. It names the conversation regardless, which is what the terminal and file tabs' wide bars do. The floating shell keeps its two buttons. It has neither this line nor a column, and they are its only way to either.
The four tabs built on MasonryList — servers, the terminal and file pickers, snippets — drew 12pt above the first card and 16 between any two, because a Card's own 4pt margin is added to the grid's padding and spacing rather than replacing them. Now 8 and 12; see the fl_lib commit for the numbers and the reason they were not the ones written down. PageColumns had the grid's spacing written out a second time, under a comment about the two agreeing. It reads the constant now, so they do.
It said "Empty" — a word for a list that could have held something, on the one page a new install opens to, where what to do is the button floating over it. The terminal, file and snippet tabs answer the same state with a faint icon and no words, on the reasoning that a sentence would be telling the reader what they are already looking at. Two call sites because they are one surface at two widths: with nothing selected there is no detail pane, so `AdaptivePanes` hands the list the whole window, and what a wide window shows when the tab is empty is that list rather than a rail beside something. The fullscreen status mode in landscape.dart still says "Empty". It is a display of its own with its own conventions and is left alone.
…e fix An end-to-end suite for the guest, on Ubuntu 26.04, keeping stderr when a case fails — and the first bug it found: a host name longer than the field `uname` copies it into killed the process. The task-root handling this app depends on is still there — `root_floor`, the root in the cache key, and `getcwd` stripping only a root longer than "/" — and both engines build with `ios/Runner/ish/sbm_ish.c` against them. Not verified on a device at this revision.
It floated over the list, which cost it two of itself — a small one for a pane and a full-size one for a single column — and covered the last row of the thing it adds to. Beside search in the bar it is one button, at one size, and the page reads like every other list in the app. The two tests that pinned the old placement now pin the new one: both actions reachable at either width, and no floating button at all.
It opened the server form. That was deliberate once — a server this app does not know cannot be browsed — but it left the tab with the wrong plus and no right one: new folder, new file and bringing one in from outside were reachable only by right-click, which a phone does not have. On mobile there was no way to add a file at all, and the only visible plus belonged to the server list. The browser's own create menu moves into its top actions, so the button opens the same three the secondary tap always gave. The tab stops offering to add a server: that is the server tab's, and this tab lists what already exists. Not offered while picking a file or a directory. Those are there to choose something that exists, not to make something new.
It had both a plus in the bar and a floating one, and each went to the server form — while the other thing this tab opens a terminal on, a Linux system on this device, had neither. Adding a server belongs to the server tab; adding a system belongs to the chip that lists them. This tab lists what can be opened. Editing a server is still a long press on its card, and the rail keeps its own.
`code` is the raw wait(2) status word. Only a normal exit puts the code in the high byte: `kernel/exit.c` calls `do_exit_group(sig)` for a death by signal, which leaves the signal in the low 7 bits and nothing above them. So `code >> 8` answered 0 for every one of them, and 0 is what `ExecResult.exitCode` means by success. Report 128 + signal, as a shell does, so a caller that knows what 143 means needs no telling. It also stays positive, which the field requires: `sbm_ish_exit_code` uses a negative value for "still running". Restore the stub branch, which has not compiled since 5f9301f put a second copy of `sbm_ish_detach` in it — the real one, referencing `booted` and `do_umount`, neither of which exists with the engine off. That is the default (`SBM_ISH = 0`); only a checkout carrying the untracked IshLocal.xcconfig was building the branch that works. Set `uname_hostname_override`. Without it the guest's hostname is the host's nodename, which on iOS is the device name: something the user typed, usually carrying their own, and reaching the guest's prompt and whatever it writes out. It is also not a hostname — the field is 65 bytes and `do_uname` truncates to fit, so a multi-byte name is cut mid-codepoint. Drop two settings that do nothing: ENGINE_ASBESTOS has had no reader since unicorn was removed, and `ish.p` is meson's private directory for the `ish` executable, which a cross build does not produce.

`shipped_migrations_keep_their_checksums` failed on windows-latest and nowhere else. sqlx hashes each migration file's bytes, `migrate!` embeds them at compile time, and the Windows runner checks out CRLF — migration 1 hashes to 1ca2d91b… there against ac7a765b… everywhere else. Reproduced locally: piping the file through `s/\n/\r\n/` gives the runner's value exactly. The test is the thing that noticed, but the consequence is not confined to CI. Those checksums go into the agent's `_sqlx_migrations`, so a build from a CRLF checkout disagrees with whatever an earlier build recorded and the migrator refuses to start. `.gitattributes` fixes the bytes at LF. Also collapse the nested `if let` in the overflow announcement, which clippy rejects under `-D warnings`. The crate is edition 2024 and `terminate_process_group` a few lines down already uses a let-chain. Still failing and not explained: `an_external_command_cannot_silently_ truncate_output` on windows-latest, which 718b03a introduced and which passes on macOS and did pass on Windows before that commit.
`an_external_command_cannot_silently_truncate_output` times out there and passes on Linux and macOS, and the failure it reported — `unwrap_err()` on an `Ok` value: None — is the timeout branch, which cannot say whether the child produced the bytes at all. Read statically the path looks the same on both: PowerShell writes MAX+1, the reader's `take` cap is reached, the overflow is announced. Something in that chain is not happening and guessing at which link would be guessing. So: report what the call returned instead of `unwrap_err`, which is worth keeping either way, and run the same PowerShell command plainly first. cargo prints a failing test's output, so the probe is only read on the run that needs it. The probe goes once the answer is in.

- Around line 78-89: Update LinuxProfile.rename to return an actionable
success/failure result instead of Future<void>, and propagate failure when
rootOf(profile.id) is null so callers can report it. Remove the facade’s direct
LinuxProfile.marker write, and move marker persistence into the corresponding
AndroidRootfs and IosRootfs rename/backend operations while preserving their
existing scan behavior.
In `@monitor/src/monitoring/monitoring.rs`:
- Around line 1491-1513: Remove the temporary Windows-only probe block that
invokes powershell with PS_WRITE and emits PROBE diagnostics. Delete the
associated Instant timing and Command execution while leaving the surrounding
test logic unchanged.
In `@scripts/check-ish-linkage.sh`:
- Around line 73-80: Update the failure message in the sbm_ish_* export check to
use a literal 'used' directly within the existing double-quoted string, removing
the nested quote-escape sequence while preserving the diagnostic text and
behavior.
In `@scripts/ensure-ish-libs.sh`:
- Around line 93-96: Update version_tag so it reads the complete git tag output
without using head -1, while still selecting and returning the highest matching
tag. Preserve the existing tag filters and version sorting, and ensure the
command remains safe with pipefail enabled.
- Around line 143-144: Update the download logic in the release-fetch flow of
ensure-ish-libs.sh to capture each curl request’s HTTP status and distinguish a
missing release from other failures. Only enter the existing local-build
fallback when the release request returns 404; propagate or report DNS, proxy,
rate-limit, checksum, and other download failures instead of labeling them “no
release $tag”. Apply the same behavior to the related flow around the second
referenced block.

Each of these was checked against the current file rather than taken from the report; the ones left undone are listed at the end. Reachable from outside: - `sbm_ish_attach`/`_detach` refused a profile containing `/` but took `..`, which every path here builds as `/<profile>/...` and normalizes straight back to the machine root. One `check_profile` for both. - `make_dev` returned void and gave up silently when its database failed, and `sbm_ish_attach` recorded the profile anyway. Attaching is idempotent by name, so that is a half-built system nothing ever retries: every later attach sees the name and returns 0, and the session opens onto a `/dev` that was never mounted. - `LiveActivityManager.start` is on an actor, which is not a lock across a suspension. A second call arriving while `request` awaited found no activity to update and asked for another — two Live Activities for one terminal, only the later one reachable. Single-flight through a `Task`. - `IosRootfs.install` picks its id from the scan that opens it, so two overlapping calls were handed the same id and the same directory. - `seedChsh` read `usr/local/bin/chsh` with `readAsString`. The comment two lines down anticipates `apk add shadow` putting a compiled binary there — decoding one throws, out of a function that runs while the app starts, before the check that would have said to leave it alone. Bounded prefix, decoded loosely, empty on failure, which reads as somebody else's file. - `IshExec`'s console decoder was strict, so a session hung up mid-character answered `close()` with a `FormatException` instead of returning output. - `stopForward` wrote to a disposed notifier: `close()` is awaited and `dispose` can run underneath it. Every other path there already checks. - `removeProfile` and `AndroidRootfs.enter` built paths from an unvalidated id. `rootOf` only joins, so anything a caller passes becomes a path — one of them a recursive delete. - `AndroidRootfs.prepare` returned before `scan()` when the native library directory was missing, leaving every installed system invisible. Whether proot is present decides what can run, not what is installed. - `chmodGuestFile` looked `chmod` up as taking a `uint16_t`, which is `mode_t` on Darwin only. `ios_rootfs.dart`'s private copy is gone. - A profile label reached the marker unescaped, and a newline in one writes a fourth line that `decode` reads as a truncated name. - Poll rearms at the idle interval after a read error rather than 60 times a second at the busy one. Tests that were not testing what they say: - `chsh_script_test` rewrote the conf path into the temp tree but left `/etc/shells` absolute, so `-l` read the host's while the test wrote a fixture nothing opened — and then asserted only the exit code. Both paths are redirected now and the output is compared. - Four integration tests called `install` unconditionally, which adds a system rather than reusing one, or removed a single profile using a distribution id where a generated profile id belongs. - `shipped_migrations_keep_their_checksums` asserted over the pinned list, so a migration added tomorrow would be pinned by nothing. Scripts: - `ensure-ish-libs.sh` unpacked a replacement over the previous revision's libraries. `have_libs` only asks whether the three are present, so one the archive did not carry survived and linked into a build it was not built for. - `version_tag` piped into `head -1` under `pipefail`. - `check-ish-linkage.sh` reached for the single-quote escape idiom inside a double-quoted string, where a single quote is already literal. Left undone, deliberately: - Reinstalling deletes the tree before downloading its replacement, so a download that fails takes the user's system with it. Real, and reachable through the update row on Android. The fix is to stage and swap, which reshapes the whole install path and wants device verification. - The pre-container `alpine/` tree: still a TODO, still nothing has shipped that needs migrating. - Hardcoded `'Linux'` in the terminal tab. `'DNS'` in the same feature is hardcoded for the same reason, and there is no such l10n key. - `Rootfs.rename` returning a result, and the Kotlin block in `android/build.gradle`: shape, not behaviour.
…startup The probe answered what it was for. On an idle Windows box the child starts, writes its megabyte and exits in 179 ms, status 0, nothing on stderr — so the command was never the problem, and neither was a cold PowerShell. It also did not reproduce. 70 runs on real Windows hardware, twelve of them concurrent, never failed; windows-latest failed three of five. The runner is roughly ten times slower and shared, and a five-second budget for a 179 ms operation is the kind of margin that holds until it does not. Which also means the earlier attribution does not survive its own evidence. Two passes before 718b03a and three failures in five after is not a sample that separates "introduced a race" from "a flake that had not landed yet", and I stated it more firmly than that. So: raise the budget to 30 seconds, because how long a machine takes to move four megabytes is not what this asserts. Detection that is genuinely broken still fails, only later. And write comfortably over the cap rather than one byte over it. At exactly `MAX + 1` the reader reaches its `take` limit in the same moment the child finishes and exits, so the overflow and the wait become ready together and the test stops being about either. Well over, the reader hits the cap while the child is still writing and then blocks on a full pipe — the case the announcement was added for. Not verified against the failure: it never reproduced here, so what this removes is the sensitivity, not a mechanism anyone has seen.

`sbm_ish_attach` mounted `/proc` and then returned when `make_dev` failed, without taking it back. `do_mount` does not ask whether the point already carries a mount, so the next attempt stacked a second procfs on the same path — one per failed attach, and only the innermost reachable to unmount. That one arrived with the make_dev error propagation in 8d2ba9e. `sbm_ish_detach` unmounted outside `attached_lock` and took it only to clear the slot. `sbm_ish_attach` holds it across its own mounts and answers 0 for any name it finds in the table, so an attach running alongside a detach read the name as still attached, returned without mounting anything, and handed back a system whose filesystems were being pulled out underneath it. The whole unmount-and-clear is under the lock now. On the failure path the name stays in the table, which is correct: its mounts are still there. No nesting to deadlock on — `is_attached` does not lock, and nothing reached from either function takes this mutex. `LiveActivityManager` had two, and the single-flight in 8d2ba9e only closed the first half. A second `start` waited for the request in flight and then took *its* result, so the newer payload was dropped; it applies its own content to the activity that comes back instead. And a `stop` arriving while a request was in flight could not end an activity that did not exist yet, so the request finished afterwards and put it in `current` — a Live Activity appearing for a terminal the user had just closed. A generation counter, and the request ends what it built rather than recording it. Not done: tests for those two. There is no XCTest target in the project, and adding one is `project.pbxproj` surgery I cannot build to verify from here. Verified: both branches of sbm_ish.c under `clang -fsyntax-only`, and the Swift file type-checks against the iOS SDK down to `TerminalAttributes`, which lives in the widget extension and is out of scope for a single file.

Included review availability: 0 reviews are currently available. Your included PR review attempts over the past 7 days set your current allowance at 2 reviews per hour.
Found while checking the review's two mount findings, and larger than either. `kernel/errno.h` defines its constants already negative — `_ENOENT` is -2 — and `sbm_ish_detach` tested `one != -_ENOENT`, which is `+2`, a value no error equals. So the "not mounted is not a failure" exemption was dead code. `do_umount` also answers `_EINVAL` rather than `_ENOENT` for a point that carries nothing, so it would not have applied even negated correctly. Every detach of a profile whose four mounts were not all present reported failure — including one that had never been attached at all, which is what `removeProfile` does when no terminal opened the system this run. The two findings and that bug are one shape, so one helper: - `unmount_profile` takes a profile's filesystems down, exempting `_EINVAL` and keeping `_EBUSY`, which are `do_umount`'s only two errors. - `sbm_ish_attach` calls it before mounting anything. Whatever is there is left over from an attempt that failed or a detach that could not finish — the profile is not in the table, so nothing considers it attached — and `do_mount` does not ask whether a point already carries a mount. It refuses when something will not go, rather than stacking over whatever holds it. - The rollback after a failed `make_dev` reports what it could not undo instead of discarding the result, and the original error still returns. - `sbm_ish_detach` clears the name whatever happened. `attached` means "mounted by us and believed good", and after a partial detach neither half holds. Leaving the name had the next attach answer 0 for a system missing its `/dev/pts`; clearing it sends that attach through the rollback, which either mounts afresh or refuses. `LiveActivityManager.pending` carries the generation that made it, so a `start` arriving after a `stop` that landed mid-request waits for the obsolete one and then asks for its own. It previously found nothing to update and returned having done nothing. A tag rather than task identity, because `Task` is a struct: a waiter that gave up puts its own request in the slot, and both resume from the same completion in an order neither controls. Not done: the concurrency tests. Still no XCTest target, still pbxproj surgery I cannot build to verify from here.
…nmounted
`make_dev` mounted a tmpfs at `/<profile>/dev/shm`, and `fs/tmp.c` answers
`umount` with `TODO("tmpfs umount")`, which is `die()`. This app installs a
`die_handler` that parks the calling thread with every signal blocked rather
than letting `abort()` take the app — and the thread that detaches a system
is the one running Dart. So the first detach of a system that had actually
been attached froze the whole app, with no crash and nothing in the log.
Found on lkpp, from the symbolicated report the freeze eventually produced:
die
tmpfs_umount
mount_remove_locked
unmount_profile
sbm_ish_detach
It explains the shape of it too. Detaching a system that was never attached
is instant, because all four points answer `_EINVAL` before any filesystem's
umount runs; only a real mount reaches `tmpfs_umount`.
Not a regression. Reproduced on both engine revisions and on both sides of
the attach/detach rework — `dev/shm` has been in the unmount list since that
list was written.
A plain 01777 directory instead. `/dev` is a fakefs over an ordinary
directory, so everything that expects to write to `/dev/shm` still can; what
changes is that the contents are on disk and go when the system does rather
than when the app does.
Verified on device, through the FFI directly: attach, detach, attach, detach,
attach on a second system, every one 0 and immediate. Then in the guest —
`echo hi > /dev/shm/probe && cat` gives `hi`, `ls -ld /dev/shm` gives
`drwxrwxrwt`, and `uname -n` gives `serverbox`, which is the override from
d07bbab and had not been seen on a device until now.
3cb7c7f2 → d97b173f, which is 17 commits: ShellBox PR #10 and what has landed since, plus the `tmpfs_umount` fix pushed for this. What is new for this side, having checked rather than taken the list on trust — several of the changes advertised for this bump were already in 3cb7c7f2 and are not reasons for it: - `tmpfs_umount` is implemented rather than `die()`. af8e489 stopped this app depending on it by not mounting a tmpfs at `/dev/shm`, so nothing here needs it today; it means the next thing that mounts one can unmount it. - `setsockopt(IPPROTO_IP, IP_RECVERR)` answered `EINVAL`, and glibc's resolver treats that as fatal. Alpine is musl and does its own DNS, so this only matters once a user installs something glibc-based. - `syncfs` was `syscall_stub` and is implemented, which an `rpm`/`dnf` transaction reaches after downloading everything. - `fake_db_create` is now a shared API. The TODO in `make_dev_db` naming it is what to do next; the local copy still stands. Already present at 3cb7c7f2 and so not part of this: the `O_DIRECTORY` value, `waitid`'s decoded status, and the ASIMD lane conversions. Verified: `ensure-ish-libs.sh` replaced the libraries, the engine links, and the app runs on lkpp — attach, detach and re-attach of a second system all answer 0, and a guest command comes back. That was with v1.0.36; the release for this revision is still building, so a checkout that beats it to the finish builds the engine locally, which the script says it will.
…mounted Nothing ended a system's sessions when the system went away. Closing a terminal tab closes that one session; deleting from the settings page closed none, and the tab that was open got closed by `Rootfs.removed` only *after* the delete. So the shell was still holding the pty that keeps `/dev/pts` busy, every unmount answered `_EBUSY`, and the delete that followed pulled the tree out from under a live fakefs mount — the next read through it was a sqlite I/O error, which the engine answers with `die()`. Seen on a device as the app freezing seconds after a delete, with `session 0 pid 2 used=1 task=alive` in the log. `sbm_ish_detach` now hangs up every session belonging to the profile before it unmounts anything. It signals and does not wait, because it holds `attached_lock` and waiting there would park the app; the wait is the caller's retry loop in `removeProfile`, which also gives a shell the time to be scheduled, take SIGHUP and exit. The rest is what that mistake needed to be visible and survivable: - `close_session` is `sbm_ish_close`'s body, split out so detach can reuse it, and it now `tty_release`s the reference `pty_open_fake` handed over. Forgetting the pointer was not giving it back. - A failed detach keeps the name in `attached` and refuses the delete, rather than clearing the name and leaving a system that could never be opened again for the life of the process. - An attach that meets busy mounts takes the profile as attached instead of refusing it, for the same reason. - `unmount_profile` logs which mount point would not go, and a failed detach logs each session's pid and whether its task is still alive.

- Around line 691-696: Update close_session to accept an optional profile and,
while holding sessions_lock, only proceed when the slot is used and either the
profile is NULL or matches sessions[i].profile; have the existing caller pass
NULL, and pass the target profile from the loop so the check and session
teardown cannot affect another profile.
In `@ios/Runner/LiveActivityManager.swift`:
- Around line 144-152: Update the pending-request coordination in start so that
after awaiting an obsolete pending.task, it re-reads pending in a loop and joins
any request installed for the current generation instead of using the stale
value. Create and assign a new request only when no pending request remains,
preserving the generation and tag checks used by the existing pending tuple.

- `close_session` takes the profile it may close and checks it under the same hold of `sessions_lock` as the teardown. Reading `used` and `profile` in the caller and closing under a second lock left a window in which `sbm_ish_open` took the freed slot for another system, and the detach hung up a session belonging to it. - `LiveActivityManager.start` loops over `pending` instead of reading it once. Waiting out a request from an ended lifetime is a suspension, and the stale value it resumed with was taken as "nothing in flight" — so it asked for an activity beside whichever request another caller had installed meanwhile. A finished stale request is dropped before the next turn, or the loop would wait on it again. - The `procfs` and `devpts` mounts are checked like the `/dev` mount already was. Discarding them let an attach report success and left the failure to be met later, as a shell that would not start.

Draft. Two months of the iOS Linux environment and the UI around it, on one branch: 35 commits, 101 files.
Linux systems on the device
Several at once, each in its own root. The machine's root is a container of trees, one subdirectory per system, and nothing runs at that level — a session is rooted at its own subtree, the way a container is. Two Alpines can sit beside each other and both run: the profile id is a generated directory name, not the distribution, which is the case keying by distribution made impossible.
A profile is a directory plus the marker in it, and nothing else — no table, no setting listing what exists. So one deleted from disk cannot linger in a list, and a list cannot promise a tree that is not there.
Selecting is not switching. Nothing is deleted when the selection moves, sessions already running stay where they are, and a terminal records which system it is in so a restored tab reopens the one it was.
Settings under Terminal > Linux, named for Linux and not a distribution: the systems with rename/update/delete, the shell an interactive terminal starts, the mirror per distribution, and the resolvers written into the guest. The mirror and the resolvers had no setting before, so a device on a network that cannot reach
dl-cdn.alpinelinux.orgended up with a Linux it could not install packages into and nothing that said so. The digest stays pinned in code while the mirror is a setting: a mirror decides where the bytes come from and never which bytes are accepted.A
chshfor systems that have none. Alpine ships none, and installing the real one would not help: it edits/etc/passwd, and nothing in this guest reads that. The stand-in writes the file that does decide — the same file the settings page reads — so there is one answer rather than two stores and a rule about which wins.The iOS engine
Needs lollipopkit/ShellBox#3 (merged): an absolute symlink target restarted from the machine root, so Alpine's

Without the first, nothing in a profile could exec at all.Around it: init no longer fork/execs a shell as fast as it can, the guest console is carried as bytes rather than through a
String(anything outside ASCII did not survive the round trip), andscripts/ensure-ish-libs.shfetches the static libraries built for the fork's exact revision — or builds them — from the Runner's build phases, so a checkout does not link yesterday's engine.Android
proot runs with
--link2symlink, without which every package carrying hard links fails on exactly those entries.wakelock_plusis compiled at the Kotlin 2.1 language level, since its generated pigeon has no package declaration and Kotlin 2.2 rejects the imports that follow from that.Terminal input
One Cmd+V pastes once. Two paths were both pasting — a global
HardwareKeyboardhandler and the view's own shortcut — and the global one ran once per open terminal, so a key also reached terminals nobody was looking at. Paste is bracketed now, so an editor stops auto-indenting what arrives and a shell stops running the newlines.UI
A session line and a walkthrough for the virtual keys; the Agent header names the conversation and opens the list; settings content starts at the top with the tabs floating over it; card grids tightened; a page pushed in a tab animates across the status bar; the Agent tab and its history rail follow the theme.

Rootfs.isOutdatedis stillisAndroid && …, from when iOS recorded no version. It records one now, so this is a three-line change — held back because offering an update means downloading the release again and losing everything installed in that tree, which is a product decision.Application Support/alpineto.../linux; an existing install reads as absent and is reinstalled.

Real isolation would need a second process, which an App Store app cannot have — see TODOS.md.Two things for the reviewer
f7bcf366and3eb42ea0do not build. They deleteclipboard_chord.dartwithout the import removal that went with it, which landed later in3589f7d9. The branch tip is fine;git bisectis not. Worth squashing on merge.packages/fl_libandpackages/flutter_ptygitlinks move here. Both need their own side merged first, or this points at commits nobody else can fetch.Summary by CodeRabbit
