Enable WiiCompiled on Linux through the AppImage - #376
Conversation
* offline play * Extract Retro-WFC payload decision policy
The Windows/Linux build is the required one. A failed macOS signing or notarization no longer blocks the release; the DMGs are attached only when their jobs produced them, and the in-app updater already picks the newest release that carries an asset for the user's platform.

WiiCompiled publishes a Linux AppImage since v0.2.26, but the recomp integration was gated behind OperatingSystem.IsWindows(). The AppImage does not speak the Windows setup's command-line contract (subcommands, its own install-state.json without a setup version, no --check-products report), so this adds a Linux implementation of IRecompInstallService that drives the AppImage as it exists today, with no change required on the WiiCompiled side. - RecompPlatform: platform gate and per-architecture release asset, shaped like the one in TeamWheelWizard#371 so both merge cleanly. The three IsWindows() gates now use it. On a Linux Flatpak the option is shown disabled with an explanation instead of hidden. - RecompSetupHostAcquirer: release lookup, download, chmod +x and --version verification, extracted verbatim from RecompInstallService and shared by both platform services. - RecompLinuxInstallService: install --game for a new release, incremental install (no --game) for repairs and Retro Rewind updates, launch-retro, uninstall. Wheel Wizard keeps a copy of the AppImage and writes the v1 install-state.json itself, so RecompInstallState, the payload policy and the status resolver are reused unchanged. - RecompLinuxProductInspector: rebuilds the --check-products report from the AppImage's install-state.json and each product's local-build.json, hashing Retro Rewind's Code.pul to detect a stale build. Fails closed. - RecompProcessRunner: SIGTERM for cooperative cancellation on Linux, and a one-time APPIMAGE_EXTRACT_AND_RUN retry when FUSE is unavailable. - Config.toml, install locations and offered graphics APIs follow the AppImage's XDG layout on Linux.

An explicit "Products": null in the AppImage's install-state.json used to overwrite the empty-list initializer on deserialization and make the product inspection throw instead of reporting both products absent. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

First off, I do appreciate the effort trying to integrate this into the app.
Some general remarks: While the installation and launching seem to work fine, the full integration (Miis, licenses, ...) is not fully implemented/functional. It seems to be a general issue with Wheel Wizard's code right now, and not just due to this work. With a Dolphin user folder enabled and the sharing toggle enabled as well, the NAND folder seems to be in sync with the created Mii showing up in both Wheel Wizard and the recompilation. This is also reflected in the Config.toml. However, the retro_rewind_root remains untouched and is currently not handled correctly, which leads to licenses not showing up due to the rksys.dat not being picked up correctly: Wiicompiled continues to run with an outdated retro_rewind_root, while Wheel Wizard tries to prioritize Dolphin's folders without caring about the Config.toml's retro_rewind_root configuration (which is a Wheel Wizard bug). So, when reviewing this PR, these existing issues need to be kept in mind.
The decisions this PR makes regarding Wheel Wizard running as a Flatpak, however, are misguided. The Wheel Wizard flatpak will be able to run the Wiicompiled AppImages, without relying on sandbox-escaping host commands. The way I will package it, Wheel Wizard will be able to be run without the org.freedesktop.Flatpak permission (though the manifest will still have it for Dolphin compatibility... as such it will be opt-out). This way, users can run Wiicompiled without having host commands easily accessible from within the sandbox -- given they won't use Dolphin. We obviously cannot rely on FUSE, but since the AppImage supports the APPIMAGE_EXTRACT_AND_RUN environment variable (or the --appimage-extract-and-run flag), we are obviously going to use it. Under these conditions (and given that the runtime has the required SDK components, which I will take care of as the maintainer of the Flatpak), the Flatpak sandbox is able to run the AppImage. So please at least address all my comments to stop special-casing the Flatpak, as this will not be needed. Obviously, the legacy libxml2 is currently required, but this is a non-issue.
So, to reference some of your points:
-
the introduced
IsLinuxFlatpakhandling needs to go -
On a Linux Flatpak, the section is shown but disabled with an explanatory tooltip instead of hidden (see limitations).
This is not what we want, the Flatpak will support Wiicompiled.
-
Flatpak: the sandbox has no FUSE, no compiler prerequisites and no view of ~/.local/share/WiiCompiled. Supporting it needs flatpak-spawn --host plus a --filesystem=xdg-data/WiiCompiled permission in the Flathub manifest; that is a follow-up. The option is shown disabled with an explanation there, so Steam Deck users on the Discover build know to use the AppImage of Wheel Wizard.
This is entirely misguided. The only reason we have
flatpak-spawn --host --permissions is to support existing Dolphin installations in a way that enables sharing of controller configurations etc. Especially since there would be version differences, and a default hostdolphin-emuuses a XDG-spec compliant split config and data paths, bundling the Dolphin emulator just wasn't a good solution either.
The only remaining issue with the AppImage that I currently see is that it seems to be lacking DynamicLauncher integration for installing the .desktop files: https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.DynamicLauncher.html. Due to this, the two .desktop files will not be picked up by e.g. a DE. I do not want to add new permissions or use existing default capabilities to just drop the desktop files onto the host filesystem to achieve this. With portal integration, this should also be solvable from within the sandbox, but it should be implemented in Wiicompiled.

Yay, linux support for wiicompiled! |
Review feedback: FUSE is nothing to rely on and the Wheel Wizard Flatpak will run the AppImage inside its sandbox, so APPIMAGE_EXTRACT_AND_RUN=1 is now set on every AppImage invocation (no FUSE attempt, no retry) and the IsLinuxFlatpak gate, the disabled toggle and its helper text are gone. Running unpacked also exposed that the AppImage runtime does not forward SIGTERM to the setup it starts: signalling only the runtime left the setup and its build orphaned. Cancellation now lists the whole process tree from /proc first, signals every process in it, waits for the redirected streams to close (which is when the setup's terminal result line has been read) and only then falls back to SIGKILL. Verified against a real install: the setup reports "cancelled" within 0.1 s and nothing is left running. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Thanks for the thorough review, and for the Flatpak context: I had the sandbox constraints wrong, and it's good news that the Flatpak will run the AppImage directly. All six inline comments are addressed in 3fe5e17:
Re-testing in unpacked mode also surfaced a real bug in my cancellation path: the AppImage runtime runs the setup in a child and does not forward SIGTERM, so cancelling killed only the runtime and left the setup, On I resolved the threads I addressed so the merge check clears; feel free to reopen any of them. |

Thanks. While this would already work in a Flatpak situation, I still have some suggestions.
Review feedback: neither command builder should own a quoting scheme. IRecompProcessRunner.RunAsync now takes the argument vector as separate values and feeds ProcessStartInfo.ArgumentList, so both builders return plain lists and the Windows and Linux Quote helpers are gone. Tests assert the vectors instead of a joined string. Also from the review of the runner: - APPIMAGE_EXTRACT_AND_RUN is keyed on the .AppImage extension of the file being run, not on !IsWindows(). - The process tree is read through `ps -e -o pid=,ppid=` instead of /proc, which works the same on Linux and macOS (.NET exposes no parent id). - The forced stop uses Process.Kill(entireProcessTree) for the root's own tree; descendants the AppImage runtime already orphaned are stopped through Process.GetProcessById(..).Kill(), since Kill(entireProcessTree) cannot see them once they are reparented. No more libc SIGKILL. Verified on a real install: cancelling still makes the setup write its "cancelled" result line and leaves nothing running.

The PR now targets dev, which carries the atomic save writes (TeamWheelWizard#310) but not yet main's recent commits this branch is built on (TeamWheelWizard#362, TeamWheelWizard#375, TeamWheelWizard#378). The one conflict was in MiiRepositoryService: main resolves the Mii database path per frontend (TeamWheelWizard#378) while dev writes it atomically (TeamWheelWizard#310). Both are kept: the atomic write now targets the resolved path, and the directory creation dev dropped stays dropped since AtomicFileHelper creates it.

Purpose of this PR:
Enable the WiiCompiled (beta) option on Linux. WiiCompiled has published a Linux AppImage since v0.2.26 (
WiiCompiled-Setup-x86_64.AppImage/-aarch64.AppImage), but Wheel Wizard still gated the whole recomp integration behindOperatingSystem.IsWindows().The Linux AppImage does not speak the Windows setup's command-line contract (see "Why a separate service" below), so this PR adds a Linux implementation of
IRecompInstallServicethat drives the AppImage as it exists today, with no change required on the WiiCompiled side. Everything user-facing (Home page install / update / play, Recomp settings, Dolphin NAND sharing, video settings, uninstall) works the same way as on Windows.How to Test:
On Linux:
dotnet run --project WheelWizard).RMCP01disc image under Settings → Locations.--version, and runsinstall --game … --retro-dir … --download-retro-wfc-payload --progress-json. Progress and cancellation (SIGTERM) work.launch-retro. Before launch, Wheel Wizard re-checks the products: if Retro Rewind'sCode.pulchanged since the build, it runs an incrementalinstall(no disc re-extraction) first.~/.local/share/WiiCompiled/Config.toml, where the Linux runtime reads them.uninstalland removes~/.local/share/WiiCompiledplus Wheel Wizard'sRecompcache.dotnet test WheelWizard.Test -p:CSharpier_Bypass=true.On Windows: no behaviour change intended. The Windows service now gets its release lookup / download / version check from the shared
RecompSetupHostAcquirer, which is a pure extraction of the code it had.Tested end to end on CachyOS (x86_64) with the WiiCompiled v0.2.28 release: enable the option, install from the Home page (Retro Rewind brought current by Wheel Wizard, Dolphin NAND sharing prompt, AppImage downloaded and version-checked,
install --game … --retro-dir … --download-retro-wfc-payload), then Play, and an online Retro Rewind race through Retro WFC. Also verified: status reads Ready afterwards, products are recognised as current, pre-launch reconciliation runs without rebuilding, and a host whose--versiondoes not match the recorded state is refused.What Has Been Changed:
Platform gate
RecompPlatform(new):IsSupported,IsLinux,SetupFileName,ReleaseAssetName(by CPU architecture), cached setup naming. Same shape and names as theRecompPlatformintroduced by Feat: Add native WiiCompiled support on Apple Silicon #371 so the two merge cleanly.IsWindows()gates (AddRecomp,IsRecompModeActive, Other settings) now useRecompPlatform.IsSupported.RecompReleaseResolver.FindLatest(releases, assetName = null): picks the asset for this platform (also as in Feat: Add native WiiCompiled support on Apple Silicon #371).Shared
RecompSetupHostAcquirer(new): finds the newest release, downloads it to the cache,chmod +xon Unix, verifies--version, prunes superseded setups. Extracted verbatim fromRecompInstallService, which now delegates to it; no Windows behaviour change.RecompProcessRunner: arguments go throughProcessStartInfo.ArgumentList. An.AppImageis always run withAPPIMAGE_EXTRACT_AND_RUN=1, so FUSE is never required: it works on distributions withoutlibfuse2and inside a Flatpak sandbox alike, and the unpack costs well under a second per invocation. On Unix, cancellation sends SIGTERM to the whole process tree (the AppImage runtime does not forward signals to the setup it starts; the tree is read throughps, which behaves the same on Linux and macOS), waits for the setup's terminal result line, and only then falls back toProcess.Kill.Linux
RecompLinuxInstallService(new): sameIRecompInstallServicesurface, driving the AppImage's subcommands. Registered on Linux byAddRecomp.RecompLinuxSetupCommandBuilder(new):install [--game] [--retro-dir …] {--download|--skip}-retro-wfc-payload --progress-json,launch-retro,uninstall,--version. Both builders return argument vectors that the runner hands toProcessStartInfo.ArgumentList; no quoting anywhere.RecompLinuxProductInspector(new): the Linux stand-in for--check-products. The AppImage only prints a text table, so the product report is rebuilt from the files it writes: itsinstall-state.json(which products exist and where) and each product'slocal-build.json(CodePulSha256), compared with the SHA-256 of Wheel Wizard'sRetroRewind6/Binaries/Code.pul. Missing executable → broken, changed Code.pul →code-pul-changed, unreadable provenance → rebuild (fail closed).RecompLinuxEnvironment(new): the AppImage keeps its products, state,Config.tomland build workspace in~/.local/share/WiiCompiled(same value .NET reports asLocalApplicationData, same place a manual AppImage run installs to). Wheel Wizard's ownRecomp/folder holds the download cache, a copy of the installed AppImage, and a v1install-state.jsonWheel Wizard writes itself (the AppImage's own state never records the setup version).RecompInstallState,RecompRetroWfcPayloadPolicyandRecompStatusResolverare reused unchanged.PathManager:RecompConfigFilePathandRecompSetupFilePathare platform-aware;IsRecompInstallPortableis false on Linux (the AppImage has no portable mode).RecompVideoConfig: Linux offers Vulkan only.en.yml: helper texts.Tests
RecompLinuxTests: command lines, argv quoting, asset selection per architecture, release resolution by asset, and the product inspector over a mocked backend layout (absent / current / Code.pul changed / missing provenance / missing executable / malformed state).Why a separate service
--silent --game … --install-dir … --portable --progress-jsoninstall --game … --progress-json(no--install-dir, no--portable)--check-productsemits aproductsNDJSON eventcheck-productsprints a text table--repair-productsinstallwithout--gameis incremental--launch-retrolaunch-retroinstall-state.json--install-dir, v1 schema withsetupVersion~/.local/share/WiiCompiled, different schema, no versionEventWaitHandleSprinkling
if (IsLinux)through the 1000-line Windows service would have touched every one of these; a second implementation keeps the Windows path byte-for-byte and makes the Linux path reviewable on its own.Known limitations
0.2.22to--version(itsModels.cswas not bumped at the tag), so Wheel Wizard's version check refuses it, as it should; v0.2.28 fixed the pin. The bundledld.lldof the current AppImages also needslibxml2.so.2, which recent distributions no longer ship; that is fixed on the WiiCompiled side by appimage: bundle the shared libraries lld depends on (libxml2, ICU) patchzyy/Wiicompiled#151. Neither is something Wheel Wizard can or should work around.RecompLinuxInstallService,RecompLinuxProductInspectorandRecompLinuxSetupCommandBuildercan be deleted as a block and Linux falls back toRecompInstallServicethroughRecompPlatform; nothing else in this PR would need to change..desktopintegration through the DynamicLauncher portal are Flatpak packaging and WiiCompiled concerns, not Wheel Wizard code.install --game); updates and repairs do not.~/.local/share/WiiCompiled/Install/…), shared with any manual AppImage install.
