Updater. New Flow - #240
Conversation
Stage the unpacked update next to the install location first, so the only non-atomic phase (cross-volume copy) happens while the current install is still intact. Verify the staged update before touching the install instead of verifying after the swap and rolling back. Then swap it into place with a single atomic exchange (renamex_np on macOS, renameat2 on Linux), falling back to two same-volume renames. Previously a crash mid-update could leave the install location empty or half-copied with no way to recover. Also abort the swap when the host process is still running after the wait timeout instead of replacing files under a live application.
Distinguish download locations for auto-installable updates (updateDataPath) and manually installed updates (downloadsPath). Track the last downloaded package to improve cleanup and enable more targeted handling. Internalize background download logic within `AppUpdateScenario`, triggering it automatically for auto-installable updates after a successful check. Simplify the `IAppUpdateScenario` public interface by removing redundant methods.
- prepareUpdate: the heavy part - validate the downloaded package and stage it for the swap. Runs in the background right after the download, while the app is still running, so failures can fall back to the manual flow with the app alive. - finalizeUpdate: the fast part - spawn the swap helper. Runs on the Restart click, which is now instant instead of freezing for seconds. On macOS the package validation is now done on the dmg itself (signature valid + same Team ID as the running bundle, ~0.1s) instead of deep-verifying the unpacked bundle (~2s); the helper still deep-verifies the staged bundle right before the swap, so that check is no longer duplicated. Development builds have no team and accept any validly signed dmg.

Inline comments:
In `@framework/stubs/update/CMakeLists.txt`:
- Line 34: Guard the add_subdirectory(qml/Muse/Update) call in the update stub
CMake configuration with the MUSE_MODULE_UPDATE_QML option, matching the
condition used by the real update module.
In `@framework/update/helper/platform_mac.cpp`:
- Around line 72-75: Update verifyInstall to avoid constructing shell command
text with path; invoke /usr/bin/codesign directly without a shell, passing the
bundle path as a single argument while preserving the existing verification
options and success result.
- Around line 57-69: Update waitForProcessExit in
framework/update/helper/platform_mac.cpp lines 57-69 and
framework/update/helper/platform_unix.cpp lines 72-83 to return true only when
kill(pid, 0) fails with errno ESRCH, and return false for EPERM or other errors.
In framework/update/helper/platform_win.cpp lines 30-33, inspect GetLastError
after OpenProcess and treat only confirmed process absence as exited; access
failures must return false. Also update the caller in
framework/update/helper/updatetask_win.cpp to check waitForProcessExit before
copying update files and abort when it returns false.
In `@framework/update/helper/swap.cpp`:
- Around line 126-184: Ensure every early failure return in the updater’s main
flow closes g_log before returning, preferably by adding an RAII scope guard
immediately after the log file is opened so normal and error exits use the same
cleanup path; preserve the existing logging behavior and final close handling.
- Around line 64-80: Update parseArgs so the --wait-pid conversion in the
waitPid assignment handles std::invalid_argument and std::out_of_range, treating
either failure as no PID to wait for while preserving valid numeric values.
- Around line 86-102: Update the cross-volume fallback in movePath to preserve
macOS bundle metadata, including extended attributes and resource forks, by
using /usr/bin/ditto or copyfile with metadata-preserving flags instead of
std::filesystem::copy. Keep the existing error handling and source removal
behavior intact.
In `@framework/update/helper/swap.h`:
- Around line 26-34: Update the documentation comment near run in swap.h to
reference updatetask_win.h instead of command_win.h, without changing the
surrounding behavior or documentation.
In `@framework/update/helper/updatetask_win.cpp`:
- Around line 278-322: Update verifySignature and the corresponding
isExpectedSigner registration/comparison flow to pin a unique certificate
identity in addition to the display-name subject, preferably the certificate
thumbprint or issuer-plus-subject. Store this identity with the registration and
require both the existing subject and the pinned identity to match before
accepting the signer.
- Around line 841-845: Update registerTask’s helperPath.empty() failure branch
to release both service and definition before returning, matching the cleanup
performed by the surrounding failure paths.
- Around line 1272-1276: Remove the privileged deletion of request.packagePath
from the cleanup flow around the update relaunch handling; retain cleanup of the
shared request file and staged copy. Do not allow the SYSTEM helper to delete
this caller-supplied path; ownership cleanup must occur in the application or
use verified file-object handling before deletion.
- Around line 155-217: Update ensureSecureRoot and the directory-creation flow
so every intermediate directory created beneath %ProgramData% is passed to
secureDirectory, starting with Muse and including Update and the app-specific
root. Preserve the existing ROOT_SDDL security settings and return failure if
securing any required level fails; do not secure only the leaf directory.
- Around line 1174-1185: Update applyRun’s staging-directory and package-copy
failure branches to delete update.req before returning 1, matching the existing
post-verification failure cleanup behavior. Ensure both
makeDirectories/secureDirectory failure and copyFileWithRetries failure remove
the request.
In `@framework/update/helper/updateui_win.cpp`:
- Around line 107-136: Replace the manual validation and hexadecimal parsing in
parseColor with the existing shared::isUiColor check from winupdateshared.h,
then convert the already-validated color value using the appropriate existing
conversion path. Preserve parseColor’s boolean success/failure contract and only
assign color for accepted values.
- Around line 150-197: Update the GetDpiForWindowFn and SetContextFn
function-pointer aliases in windowDpi and makeProcessDpiAware to match the
repository’s Uncrustify formatting, removing the space before each parameter
list; apply only the formatter’s expected style change.
- Around line 479-495: Update postCommand and postText so a failed PostMessageW
call releases the heap-allocated std::wstring payload; preserve handleCommand’s
ownership transfer on successful posts and avoid deleting non-pointer payloads
such as colors.
In `@framework/update/helper/updateui_win.h`:
- Around line 35-47: Update the command name constants in namespace command,
including TITLE, MESSAGE, BACKGROUND, ACCENT, FOREGROUND, SHOW, PROGRESS, and
CLOSE, from inline const char* to inline constexpr const char* so the pointers
themselves cannot be reassigned. Apply the same constexpr declaration pattern to
the REG_VALUE_* names in winupdateshared.h.
In `@framework/update/internal/appupdatescenario.cpp`:
- Around line 228-232: Update the result check in the interactive() callback to
proceed with the update only when res.isButton(restartBtn) is true; resolve
cancellation for every other result, including dialog dismissal. Capture
restartBtn in the lambda alongside the existing captures.
- Around line 172-180: Update the package reuse condition in the surrounding
update flow to require service()->isReleaseDownloaded() before accepting
service()->downloadedReleasePath(). If the release is not confirmed downloaded,
continue through the existing download dialog path; preserve the current
handling for a valid downloaded package and download errors.
- Around line 309-324: Update both progress handlers in the download flow to
register with Asyncable::Mode::SetReplace, preventing duplicate callbacks when
the reusable Progress object is attached again. Also change the routine progress
log in the progressChanged handler from LOGE() to LOGD(), while preserving the
finished-handler behavior.
- Around line 197-213: Make prepareAndInstall lifetime-safe when
AppUpdateScenario is destroyed: ensure the Concurrent::run worker is cancelled
and joined before destruction, or move its work into state that outlives the
scenario. Update the service() access and Async::call(this, ...) registration so
neither can dereference a destroyed AppUpdateScenario, while preserving the
existing update-install completion flow.
In `@framework/update/internal/appupdateservice.cpp`:
- Around line 237-244: In downloadRelease(), validate m_lastCheckResult.ret and
ensure info.fileName is non-empty before constructing finalPath, partialPath, or
updating configuration. Return a clear error immediately when the check result
is invalid, while preserving the existing path-building flow for valid release
data.
- Around line 280-312: Set m_downloadInProgress to true before starting the
network request and registering the downloadProgress finished handler, then
remove the later assignment. If initiating the request fails synchronously,
reset m_downloadInProgress to false before returning the error; preserve the
handler’s existing cleanup behavior for asynchronous completion.
- Around line 559-588: Update AppUpdateService::cleanupStalePackages so its
scan/removal logic only considers downloaded package artifacts and their .part
files, while preserving unrelated directories and files such as staging,
museupdater, and museupdater.log. Keep the existing retention behavior for
keepFileName and its partial file.
In `@framework/update/internal/downloadfiledevice.cpp`:
- Around line 69-73: Update DownloadFileDevice::writeData to detect partial
writes from m_stream.write(), set the device error, and return -1 when fewer
than len bytes are written; otherwise return the written count. Update
NetworkManager::readyRead() to check the writeData result and propagate -1 so
AppUpdateService::downloadRelease() cannot promote a truncated package.
In `@framework/update/internal/platform/linux/linuxupdateinstaller.cpp`:
- Around line 157-206: Update finalizeUpdate to call isInPlaceUpdateSupported()
immediately before starting the detached helper, after validating the AppImage
path and before QFile::copy or QProcess::startDetached; return
Ret::Code::NotSupported when the check fails so the application does not quit
when replacement is not currently writable.
- Around line 127-155: Add authenticity verification to
LinuxUpdateInstaller::prepareUpdate after isAppImageFile and before changing
permissions or returning the package path; validate the staged package using the
project’s existing signed-checksum or detached-signature mechanism, and reject
with an error log and failure result when verification fails so unverified files
cannot be swapped or relaunched.
In `@framework/update/internal/platform/mac/macupdateinstaller.cpp`:
- Around line 94-99: Update the staging setup in unpackDmg to check the results
of staging.removeRecursively() and QDir().mkpath(stagingDir); fail early before
unpacking when removal or directory creation fails, preventing ditto from
operating on a missing or stale staging directory.
- Around line 68-73: Update the writability condition in the mac in-place update
support check to use OR semantics, so it returns false when either the bundle
path or its parent directory is not writable. Preserve the existing access
checks and return behavior.
In `@framework/update/internal/platform/win/winupdateinstaller.cpp`:
- Around line 133-143: Prevent unbounded registry-string reads in both helpers:
in framework/update/internal/platform/win/winupdateinstaller.cpp lines 133-143,
use the byte count returned through size, trim trailing NULs, and construct the
QString with the bounded length; in framework/update/helper/updatetask_win.cpp
lines 255-265, construct the std::wstring using the length derived from size
instead of the null-terminated-buffer constructor.
In `@framework/update/internal/platform/win/winupdateshared.h`:
- Around line 205-216: Update expandInstallArgs to reject installDir values
containing double quotes or control characters before constructing the quoted
command-line value, and document that callers must validate installDir. Preserve
normal expansion for valid paths and ensure invalid input cannot be inserted
into the command text.
- Around line 62-71: Update programDataPath() to obtain the trusted system path
via SHGetKnownFolderPath(FOLDERID_ProgramData, ...) instead of reading the
ProgramData environment variable. Release the returned known-folder buffer,
return the resolved path on success, and propagate failure as an empty result so
stagingDirPath, detachedHelperPath, logFilePath, and their callers can handle
it; remove the hard-coded fallback.
In `@framework/update/internal/updateconfiguration.cpp`:
- Around line 161-163: Update UpdateConfiguration::downloadsPath and the
packagesDir/cleanupStalePackages flow so persisted package paths are confined to
an updater-owned subdirectory, or validate that each recorded path is
updater-owned before removing it, including its .part file. Preserve cleanup for
valid updater package paths while preventing deletion of arbitrary files in the
global Downloads directory.
In `@framework/update/qml/Muse/Update/UpdateBanner.qml`:
- Around line 74-82: Update the ready-update action in UpdateBanner’s
FlatButton/onClicked flow so it opens AppReleaseInfoDialog.qml before
installation, or add a separate details action that does so. Preserve access to
the ready dialog’s release notes, “Remind me later,” and “Skip this version”
actions instead of always calling updateBannerModel.install() directly.
In `@framework/update/tests/appupdateservice_tests.cpp`:
- Around line 508-531: Add tests for the remaining resume outcomes in
downloadRelease: verify HTTP 416 after a ranged request removes the partial
file, and verify successful HTTP 206 promotes the partial file to the final
path. Update givenAvailableRelease test stubs so updateDataPath() and
downloadsPath() return distinct paths, allowing packagesDir() to validate the
correct directory selection.
- Around line 144-162: Update givenAvailableRelease and the affected
AppUpdateService tests to use a per-test QTemporaryDir instead of the hardcoded
"/tmp/upd" path. Add the temporary-directory member and reuse a packagePath
helper for expected paths, ensuring all update/download filesystem operations
target the test-specific directory.

Windows OpenProcess SYNCHRONIZE ERROR_INVALID_PARAMETER nonexistent process ERROR_ACCESS_DENIED documentation
💡 Result:
When calling the Windows OpenProcess function, the specific error codes you receive provide information about why the operation failed [1]. ERROR_INVALID_PARAMETER (87) This error typically occurs when the provided process ID (PID) is invalid or refers to a special system process that cannot be opened [1][2][3]. Specifically, attempting to open the System Idle Process (PID 0) will result in ERROR_INVALID_PARAMETER [1][3]. This error can also occur if the PID is incorrectly parsed or passed to the function [2][4]. Note that OpenProcess only works on existing local processes; if the process has already terminated, the function may fail [2][5]. ERROR_ACCESS_DENIED (5) This error occurs when the caller does not have sufficient access rights to open the specified process [1][6]. The Windows system checks the requested access rights (such as SYNCHRONIZE) against the target process's security descriptor [1][6]. - System Protections: Certain critical system processes, such as parts of the Client Server Run-Time Subsystem (CSRSS), are protected by the OS to prevent user-level code from opening them, which results in ERROR_ACCESS_DENIED [1][3]. - Privilege Requirements: Even if a process is not explicitly protected, you may need higher privileges (such as running as Administrator) or the SeDebugPrivilege to obtain certain levels of access [1][3]. - Independent Access Rights: Different access rights (e.g., SYNCHRONIZE vs. PROCESS_QUERY_LIMITED_INFORMATION) are independent [7]. It is possible to be denied one right while being granted another, depending on the target process's security settings [7]. Documentation and Best Practices The official OpenProcess documentation confirms that specifying the System Idle Process (0x00000000) causes an ERROR_INVALID_PARAMETER failure [1]. For general access issues, ensure you are requesting only the minimum required access rights [6]. If you must open highly privileged processes, consider enabling SeDebugPrivilege, though this does not guarantee access to all system-protected processes [1][7][3]. If you only need to wait for a process to exit, requesting the SYNCHRONIZE access right is generally sufficient [7][6].

Abort the update when process state is unknown.
On POSIX, return true only when kill(pid, 0) sets errno to ESRCH. Return false for EPERM and other errors in both platform implementations.
On Windows, inspect GetLastError() after OpenProcess. Treat only a confirmed nonexistent process as exited. Return false for access failures.
In framework/update/helper/updatetask_win.cpp, check the return value before copying update files. The current caller ignores waitForProcessExit and continues when the host remains running.

Guard std::stoll against invalid input.
std::stoll throws std::invalid_argument or std::out_of_range. --wait-pid comes from the caller's command line. An unparsable value terminates the helper through an uncaught exception, after the host application has already decided to quit. The result is no update and no log line.
Parse defensively and treat a bad value as "no PID to wait for".

C++ std::filesystem::copy macOS extended attributes resource forks code signature xattrs
💡 Result:
The C++ standard library's std::filesystem::copy function is not guaranteed to preserve macOS-specific metadata, such as extended attributes (xattrs), resource forks, or the integrity of code signatures [1][2][3]. Because std::filesystem::copy is designed to be a portable, cross-platform interface, its implementation on macOS typically relies on standard POSIX system calls. These do not natively handle the specialized metadata structures required by macOS to maintain bundle integrity, code signing, and Gatekeeper validation [2][3]. If you use this function to copy application bundles or signed binaries, you risk corrupting the code signature or losing necessary extended attributes, which will cause the operating system to reject the file or app [3]. For operations requiring the preservation of macOS-specific metadata, you should use native Apple tools or APIs instead of std::filesystem::copy [3]: 1. Use the ditto command-line tool: ditto is designed specifically to copy directory hierarchies and files while correctly preserving extended attributes, access control lists (ACLs), resource forks, and code signatures [3]. Example: execFileSync('ditto', [sourcePath, destPath], { stdio: 'pipe' }); 2. Use the copyfile(3) C API: If you require a programmatic approach within a C++ application, use the macOS-specific copyfile function [4][5]. It explicitly supports the preservation of extended attributes and metadata through flags such as COPYFILE_XATTR and COPYFILE_METADATA [4][5][6]. After any copy operation involving signed code, it is highly recommended to verify the integrity of the code signature using the codesign command-line utility to ensure the bundle remains valid [3].

macOS codesign --verify --deep --strict bundle missing extended attributes resource fork
💡 Result:
The error "resource fork, Finder information, or similar detritus not allowed" during macOS code signing indicates that your application bundle contains files with forbidden extended attributes (xattrs) [1][2]. Since macOS Sierra, code signing enforces a strict security policy that prohibits these metadata "detritus" (such as com.apple.FinderInfo or com.apple.ResourceFork) within signed bundles, as they can represent security risks or legacy data that interferes with modern code signing [1][3][2]. Steps to diagnose and resolve this issue: 1. Identify the offending files: Use the following command in Terminal to list all files in your app bundle that possess extended attributes [1][3]: xattr -lr <path_to_app_bundle> This will reveal files carrying attributes like com.apple.FinderInfo, com.apple.ResourceFork, or the more recent com.apple.provenance, which is often added by the system when copying files [3][4]. 2. Remove the prohibited attributes: To clear all extended attributes from your app bundle recursively, run [1][2]: xattr -cr <path_to_app_bundle> This command is the standard way to strip away the "detritus" and allow the codesign tool to process the bundle [1][5]. 3. Prevent recurrence: * Avoid modifying files inside your bundle via Finder (e.g., using "Show Package Contents") after they have been processed or signed, as this can introduce Finder metadata [1][5]. * Audit your build pipeline: Ensure that your build process (scripts, copying tools, or packaging utilities) is not introducing these attributes. For instance, if you are using automated tools or CI/CD pipelines, verify that they are not automatically appending provenance or other system metadata to your artifacts [4]. * Bundle structure: Ensure your bundle structure conforms to standard macOS expectations. Placing code in incorrect, non-standard locations can lead to complex signing issues that might trigger these or similar errors [6][7]. Note on --deep and --strict: The --deep option is frequently used with codesign to recursively validate nested components, while --strict ensures the validation adheres to the strictest requirements enforced by Gatekeeper [8][9]. These flags are performing their intended job by alerting you to the presence of these disallowed attributes [8]. Do not rely on removing these flags to solve the error; instead, address the underlying metadata that is causing the validation failure [6].

site:developer.apple.com codesign verify extended attributes existing code signature copy bundle ditto
💡 Result:
In macOS, a properly structured and signed app bundle should not rely on extended attributes (EAs) for its code signature [1][2][3]. When a bundle is correctly signed, all signatures are stored within the Contents/_CodeSignature/CodeResources file, which is preserved by standard file copying and archiving tools [3]. If you find that your code signature depends on extended attributes—typically occurring with non-Mach-O executables like scripts—it indicates a violation of recommended bundle structure, as these signatures are brittle and often lost during file transfers [1][2][3]. Regarding tools and best practices: 1. Copying Bundles: While tools like ditto are capable of preserving extended attributes, relying on them for code signing integrity is discouraged [4][5][6]. If your app requires them, you are likely off the beaten path [7]. Instead, restructure your bundle to place non-Mach-O executables in Contents/Resources, where codesign will automatically place their signatures in the CodeResources file [1][3]. 2. Archiving (e.g., for distribution): Avoid using the --sequesterRsrc flag with ditto when creating ZIP archives for distribution [5][6]. This flag can cause issues with notarization and Gatekeeper by incorrectly sequestering extended attributes that should not be part of the distribution [5][6]. 3. Verification: Always use codesign --verify --deep to validate your app bundle, as this ensures that nested code and resources are correctly covered by the signature [1]. 4. Troubleshooting: To inspect extended attributes on your bundle, use xattr -lr <path_to_app_bundle> [8]. If you encounter build errors regarding forbidden extended attributes (like Finder info or resource forks), you can clear them using xattr -cr <path_to_app_bundle> [8]. In summary, the most robust approach is to ensure your bundle architecture complies with Apple guidelines so that no part of your code signature relies on extended attributes [1][2].

libc++ filesystem copy macOS copyfile extended attributes implementation
💡 Result:
On macOS, the libc++ implementation of std::filesystem::copy and std::filesystem::copy_file leverages the system's copyfile(3) API to perform file operations [1][2][3]. The copyfile(3) API is explicitly designed to handle file metadata, including extended attributes (xattrs), access control lists (ACLs), and POSIX permissions [4][5][6]. When libc++ invokes copyfile to perform a copy, it typically relies on the system's default behavior for these flags [3][7]. Key implementation details include: 1. Use of copyfile(3): The libc++ filesystem implementation on Darwin (macOS) uses copyfile(3) (and historically, fcopyfile) because it provides a highly efficient, system-native way to copy files, including support for APFS clone-on-write operations (via COPYFILE_CLONE) [1][3][7]. 2. Extended Attribute Handling: The copyfile(3) API supports the COPYFILE_XATTR flag, which specifically instructs the system to copy the source file's extended attributes [4][5]. When copyfile is called without specific restrictions, it defaults to behaviors that include metadata preservation, effectively transferring extended attributes from the source to the destination [4][5]. 3. Evolution of Implementation: The implementation has evolved to improve efficiency. While early iterations relied heavily on the higher-level copyfile(3) function, newer versions have transitioned to using the lower-level clonefile(2) system call for performance (APFS cloning), falling back to copyfile(3) when cloning is not applicable or fails [1][7]. In summary, because libc++ on macOS delegates the underlying copy operation to the platform-native copyfile(3) facility, extended attributes are preserved by default as part of the system's standard file copy behavior [4][5][3].

site:developer.apple.com "codesign --verify" "resource fork" bundle
💡 Result:
The codesign tool does not simply "verify" resource forks; rather, it strictly prohibits their presence within app bundles [1]. Since the release of iOS 10, macOS Sierra, watchOS 3, and tvOS 10, Apple has enforced a security hardening policy that forbids files within an app bundle from containing extended attributes such as resource forks or Finder information [1]. If you attempt to sign or verify a bundle that contains these files, the codesign process may fail with the error: "resource fork, Finder information, or similar detritus not allowed" [2][1]. To resolve this, you must remove these extended attributes from your app bundle. You can audit your bundle for these files using the following command [1]: xattr -lr <path_to_app_bundle> To remove all extended attributes and resolve the error, use the xattr utility [1]: xattr -cr <path_to_app_bundle> Additionally, if you are working with Xcode projects, the dot_clean utility can be used to clean up these problematic files (often referred to as "dot files" or Apple Double files) that may have been introduced by copying project files to non-HFS+ formatted drives [3][4]. dot_clean /path/to/your/project_folder It is recommended to zip Xcode project folders using Finder before transferring them to non-HFS+ drives to prevent the creation of these files in the first place [4].

site:developer.apple.com codesign verification extended attributes resource forks existing signed bundle
💡 Result:
In the context of macOS code signing for application bundles, extended attributes and resource forks are generally treated as prohibited "detritus" that can cause signing to fail, rather than being part of the verified bundle content [1][2]. Key points regarding their handling: Prohibition in Bundles: Modern macOS code signing (since iOS 10/macOS Sierra) explicitly forbids any file within an application bundle from containing extended attributes that hold resource forks or Finder information [1]. If the codesign utility encounters these, it will trigger an error: "resource fork, Finder information, or similar detritus not allowed" [1][2]. This is a security hardening measure to ensure bundle integrity [1]. How Verification Works: For a standard application bundle, codesign hashes all files and stores these hashes in the CodeSignature/CodeResources file [3][4]. This creates a "seal" over the bundle's contents [5][3]. Because the signature protects the entire bundle through these hashes, the presence of external metadata like resource forks (often associated with "." AppleDouble files) on a file system can break the signature or cause verification failures if they are interpreted as part of the file, or if they prevent the bundle from being copied/distributed correctly [6][2]. The use of extended attributes to store signatures is reserved for non-Mach-O files (like standalone scripts) that exist outside of a bundle [5][7][8]. Within a properly structured application bundle, all file signatures are stored within the CodeSignature directory, not as extended attributes on the individual files [4]. Troubleshooting: To identify problematic files containing these attributes, you can use the command: xattr -lr <path_to_app_bundle> [1]. To resolve signing errors caused by this "detritus," developers are advised to remove these attributes using: xattr -cr <path_to_app_bundle> [1]. Files prefixed with "." (AppleDouble files) are a common cause of these errors and can be cleaned using the dot_clean utility [6].

Preserve macOS bundle metadata in the cross-volume fallback.
On macOS, libc++ uses fcopyfile(..., COPYFILE_DATA), so std::filesystem::copy omits extended attributes and resource forks. This does not prove that codesign --verify --deep --strict fails for every copied bundle, because normal code signatures reside in the bundle and embedded binaries. Use /usr/bin/ditto or copyfile with metadata-preserving flags for this fallback.

Escape or reject the install directory before it is placed in a command line.
expandInstallArgs wraps installDir in quotes only. applyRun in framework/update/helper/updatetask_win.cpp (Lines 1220-1247) appends the result to the command line of the staged installer, which runs as SYSTEM. A registered InstallDir value that contains a quote character terminates the quoted argument and injects further arguments into that command line. InstallDir is HKLM data written by the installer, so this is defense in depth rather than an open path, but the expansion is the single point where the value becomes command text.
Reject an installDir that contains " or control characters, and document that the caller must validate it.

Keep package cleanup inside an updater-owned directory.
When automatic installation is disabled, packagesDir() uses the global Downloads directory. cleanupStalePackages() removes the persisted package path and its .part file without validating that the path belongs to the updater. Store packages in an updater-owned subdirectory, or validate the recorded path before removal.

Provide a non-install path from the ready-update banner.
Line 81 starts installation directly. The banner has no action that opens AppReleaseInfoDialog.qml. Users therefore cannot view release notes, select “Remind me later”, or select “Skip this version” after the update becomes ready.
Add a details action or route the banner through the ready-install dialog before installation. This must preserve access to the ready dialog actions.

Do not use a hardcoded /tmp/upd path in these tests.
downloadRelease constructs a real DownloadFileDevice, and that device writes through io::FileStream instead of the injected FileSystemMock. The tests therefore touch the real filesystem at the hardcoded dataPath. Two consequences follow:
- On Windows,
/tmp/updis not a valid path, so the device fails to open. The tests still pass because no assertion covers the device, which hides the failure. - Repeated runs leave real files behind in
/tmp/upd.
Use a per-test temporary directory instead of a fixed absolute path.

Add tests for the remaining resume outcomes.
The new tests cover a fresh download, a resumed request, promotion after HTTP 200, a duplicate request, and HTTP 200 after a range request. Two production branches stay uncovered:
- HTTP 416 after a range request (Line 294 in
framework/update/internal/appupdateservice.cpp), which must also delete the partial file. - A successful resumed download (HTTP 206), which must promote the partial file to the final path.
Also note that givenAvailableRelease stubs updateDataPath() and downloadsPath() with the same value. packagesDir() therefore returns the same path on both branches, so the tests cannot detect a wrong directory choice. Use distinct values to cover that branch.

What
MuseScore Studio can now update itself in place: check → background download → show banner → instant restart into the new version. Previously the app only opened a downloaded installer and left the user to finish the update by hand.
Update flow
The museupdater helper
A standalone, zero-runtime-dependency binary embedded next to the app binary. It waits for the app to exit, verifies the staged install, swaps it into place atomically (
renamex_np(RENAME_SWAP)on macOS,renameat2(RENAME_EXCHANGE)on Linux, with a backup-rename fallback) and relaunches. Verification happens on staging before the swap: a bad update can never replace a working install, even for a moment.To test it you need to enable DevTools +
