From 0cfe1b65f381b6eaf27023438630a3d5e71f3444 Mon Sep 17 00:00:00 2001 From: Flavio Fois Date: Fri, 6 Feb 2026 18:50:11 +0100 Subject: [PATCH] Adds self-hosted update system Implements a self-hosted update mechanism, allowing the application to be updated from a corporate network share without relying on third-party services. This includes: - Functionality to check for updates - Download installers - Verify checksums - Install updates with UAC elevation Configuration is managed via the config.ini file, with automatic checks on startup. A new settings UI is also included. --- DOCUMENTATION.md | 83 +++ UPDATER.md | 169 ++++++ app.go | 32 ++ app_update.go | 528 ++++++++++++++++++ backend/utils/ini-reader.go | 4 + config.ini | 5 +- frontend/src/lib/components/MailViewer.svelte | 4 - frontend/src/routes/(app)/+layout.svelte | 22 + .../src/routes/(app)/credits/+page.svelte | 4 +- .../src/routes/(app)/settings/+page.svelte | 220 +++++++- installer/installer.iss | 40 +- installer/sample_version.json | 14 + 12 files changed, 1113 insertions(+), 12 deletions(-) create mode 100644 UPDATER.md create mode 100644 app_update.go create mode 100644 installer/sample_version.json diff --git a/DOCUMENTATION.md b/DOCUMENTATION.md index db0e4df..6ec0e1e 100644 --- a/DOCUMENTATION.md +++ b/DOCUMENTATION.md @@ -45,6 +45,7 @@ EMLy is built using the **Wails v2** framework, which combines a Go backend with │ ├── app_bugreport.go - Bug reporting system │ │ ├── app_settings.go - Settings import/export │ │ ├── app_system.go - Windows system utilities │ +│ ├── app_update.go - Self-hosted update system │ │ └── backend/utils/ - Shared utilities │ └─────────────────────────────────────────────────────────┘ ``` @@ -200,6 +201,7 @@ The Go backend is split into logical files: | `app_bugreport.go` | Bug reports: `CreateBugReportFolder`, `SubmitBugReport`, `zipFolder` | | `app_settings.go` | Settings I/O: `ExportSettings`, `ImportSettings` | | `app_system.go` | System utilities: `CheckIsDefaultEMLHandler`, `OpenDefaultAppsSettings`, `ConvertToUTF8`, `OpenFolderInExplorer` | +| `app_update.go` | Update system: `CheckForUpdates`, `DownloadUpdate`, `InstallUpdate`, `GetUpdateStatus` | #### Core Methods by Category @@ -695,6 +697,87 @@ Special handling for Italian Posta Elettronica Certificata (PEC): - Handles P7S signature files - Processes daticert.xml metadata +### 8.
