From 166535cb801238e19a39ff42911389b73a70ec20 Mon Sep 17 00:00:00 2001 From: Tyrie Vella Date: Wed, 17 Jun 2026 09:14:59 -0700 Subject: [PATCH 1/3] Installer: switch to versioned folder layout with Current junction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces flat {app}\ deployment with versioned Versions\\ + Current junction. Eliminates PendingUpgrade staging flow — new version goes to new folder, junction swaps atomically, mounts continue running from old version until unmounted. Changes: - [Files]: Deploy to {app}\Versions\{version}\ instead of {app}\ - [Registry]: PATH points to {app}\Current (junction) instead of {app}\ - [Dirs]: ProgramData under versioned folder - [Code]: Add CreateOrUpdateCurrentJunction() — creates/updates junction post-install - [Code]: Add GarbageCollectOldVersions() — keeps 1 most recent old version, deletes older (skips versions with running mounts detected via Get-Process gvfs.mount | .Path) - [Code]: Remove KeepMountsRunning variable, IsNormalInstall/IsStagingInstall checks - [Code]: Remove StagingUpdateService, ShowMountChoiceDialog (no longer needed) - [Code]: Simplify PrepareToInstall — no mount detection, no staging, just stop service - [Code]: Update InstallGVFSService to reference {app}\Current\GVFS.Service.exe - [Code]: Update MountRepos, MigrateConfigAndStatusCacheFiles, WriteOnDiskVersion16CapableFile to use Current junction paths - CurStepChanged: Remove staging logic, call CreateOrUpdateCurrentJunction + GarbageCollectOldVersions - CurUninstallStepChanged: Remove {app}\Current from PATH instead of {app} Flat-layout migration stub added (detects {app}\GVFS.exe, logs version) but defers actual file move to future PR to reduce complexity.

Forward reference violation - Move CreateOrUpdateCurrentJunction, GetFileVersion, IsProcessRunningFromPath, and GarbageCollectOldVersions before CurStepChanged. Inno Setup Pascal does not allow forward refs. 2. Service starts before junction exists - Create Current junction in CurStepChanged(ssInstall) BEFORE file extraction, ensuring the junction exists when InstallGVFSService runs (AfterInstall callback during file copy). Service binPath references {app}\Current\GVFS.Service.exe. 3. Old PATH entry not cleaned up - On upgrade from flat to versioned layout, remove legacy {app} PATH entry in CurStepChanged(ssPostInstall). New entry points to {app}\Current. 4. Non-atomic junction swap - Use Current.new temporary: create junction at Current.new, rmdir old Current (check ResultCode), rename Current.new to Current. Eliminates window where Current doesn't exist. 5. Add upgrade test scenarios - Add versioned-fresh-install, versioned-upgrade, and flat-to-versioned-upgrade scenarios to .github/workflows/upgrade-tests.yaml with full test implementations.

SYSTEM uses ProgramData; per-user uses platform default. Seed-on-first-use copies accessible entries from system registry. - LogonTaskRegistration: machine-wide \GVFS\AutoMount task fires for all interactive users (GroupId S-1-5-4) at logon, runs gvfs service --mount-all. Each user's repos loaded from their own LocalRepoRegistry. - ProjFS boot task: enable-projfs-on-all-drives.ps1 enables ProjFS and attaches PrjFlt on all volumes. Embedded in task XML via build-task-xml.ps1 with SHA-256 hash marker for drift detection. - CLI verb fallbacks: mount/unmount/service verbs fall back to LocalRepoRegistry when the service named pipe is unavailable. - GVFSVerb: silent-success fallback for PrjFlt FilterAttach. - InProcessMount: restore exception safety net in HandleRequest. Installer: - Stop and delete GVFS.Service on upgrade from older versions. - Register \GVFS\AutoMount logon task. - Remove service deployment, install, start from [Files]/[Run]. - Remove PendingUpgrade staging logic and ShowMountChoiceDialog. - Exclude GVFS.Service.exe from payload (layout.bat). Functional tests: - Remove service install/uninstall (no service to test against). - Settings.cs auto-detects user-mode gvfs at %LocalAppData%\VFSForGit\Current. 926 unit tests pass.
