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.
📝 WalkthroughWalkthroughThe update framework adds persistent update configuration, resumable file downloads, background update preparation, and ready-update notifications. It introduces platform-specific installers for Linux, macOS, and Windows, with a fallback stub. Standalone helper workflows stage, verify, replace, and relaunch installations. Windows adds Task Scheduler integration and a progress window. QML now displays ready updates and installation actions. Tests cover partial downloads, range requests, promotion, concurrent downloads, and invalid resume responses. Merge Risk: 🟠 High · up to This PR changes updates from manual installer handoff to automatic in-place replacement, but the current implementation still has unresolved security and update-integrity defects across Windows, macOS, and Linux. These could install unintended software, select an outdated build, corrupt or disable an installation, or prevent relaunch, so the PR is not merge-ready until the high-impact issues are fixed. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

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.

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.

Close the pipe handle after the reader thread ends.
CancelSynchronousIo(thread) unblocks the reader thread, but it does not guarantee that the thread has left ReadFile. The code then closes pipe while readerThread may still use context->pipe. A closed handle value can be reused by another handle in this process, so the reader can then read from an unrelated object. The wait also has a 2000 ms timeout, after which the thread may still be running and still delete context.
Wait for the thread first, then close the pipe.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Do not accept any signed package when the team identifier cannot be read.
teamIdentifier returns an empty string for three different outcomes: an ad-hoc signature, a missing TeamIdentifier= line, and a codesign failure. verifyPackageSignature treats all three as "development build" and returns success without comparing teams. A signed release bundle whose team identifier cannot be read at that moment therefore accepts a package signed by any Developer ID.
Distinguish "no team" from "could not read the team". Fail closed when codesign fails on the running bundle.
🔒 Proposed direction
-static QString teamIdentifier(const QString& path)
+//! `ok` reports whether the signature could be read at all; the returned team
+//! is empty for an ad-hoc signature.
+static QString teamIdentifier(const QString& path, bool& ok)
{
+ ok = false;
QProcess codesign;
codesign.start("/usr/bin/codesign", { "-dv", "--verbose=4", path });
codesign.waitForFinished(-1);
if (codesign.exitStatus() != QProcess::NormalExit || codesign.exitCode() != 0) {
return QString();
}
+ ok = true;Then reject the update when ok is false for the running bundle, and keep the current pass-through only when ok is true and the team is empty.

💡 Result:
The SetNamedSecurityInfo function is designed to modify the security descriptor of an object specified by name [1][2]. When operating on NTFS file system objects, such as files or directories, the function acts directly on the object specified by the path [1][2]. In the context of reparse points—which include symbolic links and junctions—SetNamedSecurityInfo does not automatically follow the reparse point to modify the target object's security descriptor [1][2]. Instead, it applies the requested security changes to the reparse point itself (i.e., the link or junction object), not the underlying target it points to. Because these functions target the object represented by the provided path, users must be aware that updating permissions on a directory that is a junction will change the access control list (ACL) on the junction itself, rather than propagating those changes to the directory being pointed to [1][2]. For operations involving entire directory trees, functions like TreeSetNamedSecurityInfo and TreeResetNamedSecurityInfo are used to propagate security information [3][4][5]. However, these functions also operate on the specified object tree and maintain the same fundamental behavior regarding reparse points: they do not traverse into targets of junctions or symbolic links during the security propagation process, as they are constrained to the scope of the path provided [3][5].

💡 Result:
The FILE_FLAG_OPEN_REPARSE_POINT flag (0x00200000) is a specialized flag used with Windows file creation APIs, such as CreateFile, CreateFile2, and CreateFile3, to control how the system interacts with reparse points [1][2][3][4][5][6]. When this flag is specified, normal reparse point processing is disabled [1][2][3]. Instead of the system resolving or traversing the reparse point (such as following a symbolic link to its target), the function attempts to open the reparse point itself [1][2][6]. Key behaviors associated with this flag include: Handle to the Reparse Point: If you open an existing file that is a symbolic link while using this flag, the returned handle refers to the symbolic link file itself, rather than the target it points to [1][2][4][6]. Conversely, without this flag, the system typically returns a handle to the target [1][2][6]. Filter Driver Independence: The function will return a handle regardless of whether the filter driver responsible for managing that specific reparse point is currently operational [1][2][3]. Restrictions: This flag cannot be used in combination with the CREATE_ALWAYS flag [1][2][3][5]. Behavior with Other Flags: If you use TRUNCATE_EXISTING or FILE_FLAG_DELETE_ON_CLOSE in conjunction with FILE_FLAG_OPEN_REPARSE_POINT, the operation is performed on the reparse point itself (e.g., the symbolic link) rather than the target [1][2][4][6]. If the target file or directory is not a reparse point, the flag is simply ignored by the system [1][2][3][5].

site:learn.microsoft.com/en-us/windows/win32/api/winbase CopyFile reparse point symbolic link
💡 Result:
When using the Windows file copy APIs, the handling of symbolic links and reparse points depends on the specific function and flags employed. Default Behavior (CopyFile) The standard CopyFile function defaults to following symbolic links [1][2][3]. If the source is a symbolic link, the function copies the actual target file rather than the link itself [1][2][3]. If the destination file already exists and is a symbolic link, the target of that symbolic link is overwritten by the source file contents [1][2][3]. Configurable Behavior (CopyFileEx and CopyFile2) When using CopyFileEx or CopyFile2, you can control this behavior using specific flags: 1. COPY_FILE_COPY_SYMLINK (0x00000800): When this flag is specified, the symbolic link itself is copied to the destination rather than the target file [4][5]. If the destination already exists as a symbolic link, the link is overwritten [4][5]. 2. COPY_FILE_OPEN_AND_COPY_REPARSE_POINT (0x00200000): Supported on Windows 10 (build 19041 and later), this flag instructs the system to copy the reparse point itself, regardless of the reparse point type [6][7]. It is the caller's responsibility to manage the meaning of the copied reparse point [6][7]. When the COPY_FILE_COPY_SYMLINK flag is not provided, the default behavior of following the link remains in effect for these functions as well [4][5].

Reject reparse points before securing the update tree.
makeDirectories(root) creates each path prefix before any security call. An attacker-controlled junction under %ProgramData%\Muse can redirect directory creation and later path-based CopyFileW operations to the junction target. secureDirectory does not reject reparse points or use a directory handle.
Open each existing directory with FILE_FLAG_OPEN_REPARSE_POINT, reject FILE_ATTRIBUTE_REPARSE_POINT, secure it by handle, and create each child only after securing its parent. Use handle-relative or equivalent reparse-safe operations for subsequent file access.

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 +
