Three deliverables shipped together so the next deployment cycle has a
clean distribution story.
(1) Auto-update of the launcher itself
---------------------------------------
- Models: RemoteManifest gains an optional `launcher` section
(LauncherInfo: version, minRequired, download {url,size,sha256},
releaseNotesUrl). Server-side, sign-manifest.php passes it through
unchanged; admins edit versions.json with the new launcher entry +
upload PSLauncher-X.Y.Z.exe to /builds/launcher/.
- Core: ILauncherSelfUpdater compares assembly version against
manifest.launcher.version using the existing SemVer parser, and
reuses DownloadManager (Range/resume/sha256 already proven on the
game ZIPs) to download the new exe into
%LocalAppData%/PSLauncher/selfupdate/.
- New project PSLauncher.Updater (~34 MB self-contained console exe):
spawned by the main app with --target / --source / --pid / --launch.
Waits for the main process to exit (or for the file lock to release),
backs up the current exe to .bak, copies the new file in place, and
restarts. .bak survives the swap so the user can roll back manually.
- App.csproj now declares Version=0.5.0 — currently shipped baseline.
PSLauncher.App.csproj sets a fixed AssemblyVersion so reflection-based
comparison works deterministically.
- MainViewModel.PromptLauncherUpdate: dialog after CheckForUpdates if
the manifest advertises a newer launcher. Download with progress in
the existing footer, then Application.Shutdown() so the Updater can
do its job.
(2) Inno Setup installer
------------------------
installer/PSLauncher.iss + build-installer.ps1 produce a single
PSLauncher-Setup-X.Y.Z.exe (~80 MB) that installs into
Program Files\ASTERION VR\PSLauncher\, drops both PSLauncher.exe and
PSLauncher.Updater.exe side by side (the updater MUST live next to
the target), creates Start Menu + optional Desktop shortcuts, and
registers a clean uninstall entry. The user's %LocalAppData%
(license, logs, cache) is intentionally untouched on uninstall — same
license survives a reinstall.
build-installer.ps1 chains dotnet publish for both projects and ISCC
in one command. README explains the bump-version workflow.
(3) HMAC-signed download URLs
-----------------------------
- New PHP route GET /api/download-url/{version} (Authorization: Bearer
<licenseKey> or ?key=...). Validates the license, checks
download_entitlement_until >= minLicenseDate of the version, and
returns a HMAC-signed URL (path|exp|licId, hash_hmac SHA-256, valid
1 h) + sha256 + sizeBytes for verification.
- /builds/.htaccess routes every *.zip request to gate.php. gate.php
validates exp, lic, sig (constant-time hash_equals), then streams
the file with Range: support so the launcher's resume keeps working.
Audit log gets a download_url_issued entry per request.
- Client-side wired transparently: LicenseService gains
GetSignedDownloadUrlAsync(version) that GETs the endpoint with the
decrypted license key from DPAPI. MainViewModel calls it before
every download; if the endpoint returns 404/401/network-error, the
client falls back to the manifest's plain download.url (graceful
degradation for setups that haven't deployed gate.php yet).
Note on PHP streaming for 14 GB ZIPs: gate.php uses set_time_limit(0)
+ ignore_user_abort(true) + 1 MiB chunked fread with periodic flush.
Works on OVH mutualisé but holds a PHP-FPM slot for the duration. If
parallel downloads scale past a few clients, switch to
mod_xsendfile or migrate /builds/ to Cloudflare R2 with native
S3-presigned URLs and remove the gate entirely.

PS_Launcher
Launcher Windows pour l'application UE5 PROSERVE : gère plusieurs versions cohabitantes, téléchargement et installation de nouvelles versions depuis un serveur, validation de license, release notes.
Composants
src/— Solution C# / .NET 8 / WPF (Visual Studio 2022 + SDK .NET 8 requis)PSLauncher.App: UI WPF (style Epic Games Launcher)PSLauncher.Core: services (Manifest, Download, Install, Process…)PSLauncher.Models: DTOs partagés
server/— Code serveur PHP 8 (à déployer souswww/PS_Launcher/sur OVH mutualisé)
Démarrage rapide (dev)
dotnet build PS_Launcher.sln
dotnet run --project src/PSLauncher.App
Pour produire un binaire autonome distribuable (un seul .exe ~70 Mo) :
dotnet publish src/PSLauncher.App -c Release
# Sortie : src/PSLauncher.App/bin/Release/net8.0-windows/win-x64/publish/PSLauncher.exe
Configuration locale
Le launcher écrit sa config dans %LocalAppData%\PSLauncher\config.json au premier lancement.
Édite serverBaseUrl pour pointer vers ton serveur :
{
"serverBaseUrl": "https://ton-domaine.com/PS_Launcher/api",
"installRoot": "C:\\ASTERION\\GIT\\PS_Launcher\\ASTERION_VR"
}
État (roadmap)
- ✅ v0.1 — Scan + lancement de versions installées
- ✅ v0.2 — Manifest distant, download ZIP, install cohabitante, release notes Markdown
- ⏳ v0.3 — Reprise (HTTP Range), retry Polly, state.json
