Pull request overview
This PR's title and description claim to address password authentication performance on low-end devices (issue #75), but the actual changes represent a massive multi-feature release that includes:
Major Scope Mismatch: Only a small fraction of changes (PasswordDialog.kt, AbstractAuthenticationFragment.kt) relate to the stated purpose. The bulk of the PR includes unrelated features and infrastructure changes.
Key Changes
- Password authentication moved to background threads with progress indicators (Android & Desktop)
- Database schema updates: added multisig support tables, wallet_type, hide_balance, and last_sync_time fields
- Gradle upgrade from 7.4 to 8.11.1 for Java 21+ compatibility
- ErgoAuth address generation feature implementation
- F-Droid distribution preparation with reproducible builds
- Multiple new utility features (hide balance, storage rent notifications, transaction filtering)
- Extensive documentation additions (8 new MD files)

The ErgoAuth address generation feature allows passing null for sigmaBoolean (line 184), but the standard authentication flow expects a non-null sigmaBoolean (line 212). If an address request accidentally gets processed as a regular authentication request, this could cause a NullPointerException when accessing sigmaBoolean. Add explicit null checking or ensure the flow separation is complete.

The WalletConfigUiLogic.saveChanges function signature changed to add an optional newHideBalance parameter with a default value of null. However, this function is called from WalletConfigFragment with the actual value (line 85), which is good. Ensure all other callers of this function across the codebase are also updated to handle the new parameter, or verify that the default null value works correctly for existing call sites.
| # PR Summary | ||
|
|
||
| ## Title | ||
| **Fix critical issues: dependency, JVM launch, Java 21 support, F-Droid prep, and add ErgoAuth address generation** | ||
|
|
||
| ## Quick Summary | ||
| This PR fixes four critical bugs and adds one major feature: | ||
| 1. ✅ **Fixed**: Build failure due to unavailable dependency | ||
| 2. ✅ **Fixed**: Windows desktop app failing to launch (CRITICAL) | ||
| 3. ✅ **Fixed**: Build failure on Java 21/24 with Gradle 7.4 (CRITICAL) | ||
| 4. ✅ **Added**: ErgoAuth address generation feature | ||
| 5. ✅ **Prepared**: F-Droid submission with reproducible builds | ||
|
|
||
| ## Description for PR | ||
|
|
||
| ### Critical Bug Fixes | ||
|
|
||
| #### 1. Dependency Fix (Issue #181) | ||
| Fixed build failure caused by unavailable `ergo-appkit` SNAPSHOT dependency. Updated to stable release 5.0.0 from Maven Central. | ||
|
|
||
| #### 2. Windows Desktop JVM Launch Fix (CRITICAL) | ||
| **Problem**: Windows x64 users unable to start application after upgrade - "Failed to launch JVM" error | ||
| **Solution**: Added JVM memory options and module access flags to jpackage configuration | ||
| - Memory: `-Xmx2048m -Xms512m` | ||
| - Module access for Java 11+ compatibility | ||
| - Prevents startup failures and OutOfMemoryErrors | ||
|
|
||
| This is a **blocking issue** affecting all Windows desktop users. | ||
|
|
||
| #### 3. Java 21/24 Build Compatibility Fix (CRITICAL) | ||
| **Problem**: Build fails on Windows 11 with JDK 21/24 - "Unsupported class file major version 65/68" | ||
| **Solution**: Upgraded Gradle from 7.4 to 8.11.1 | ||
| - Gradle 7.4 only supports Java 8-17 | ||
| - Gradle 8.11.1 fully supports Java 8-24 | ||
| - No code changes required | ||
| - All plugins remain compatible | ||
|
|
||
| This is a **blocking issue** for developers using Java 21 or newer (including Java 24). | ||
|
|
||
| ### New Features | ||
|
|
||
| #### 3. ErgoAuth Address Generation | ||
| Implemented `generateAddressLink` feature improving dApp integration UX: | ||
| - **Before**: Manual address entry or double QR scanning required | ||
| - **After**: Single QR scan, wallet automatically provides address with cryptographic proof | ||
| - **URI Pattern**: `ergoauth://${url}/generateAddressLink/${uuid}/#P2PK_ADDRESS#/` | ||
| - **Response**: `{signedMessage, proof, changeAddress, addresses[]}` | ||
|
|
||
| ### Improvements | ||
|
|
||
| #### 5. F-Droid Distribution Preparation | ||
| Complete preparation for F-Droid submission including: | ||
| - F-Droid metadata and Fastlane descriptions | ||
| - Reproducible build scripts | ||
| - SOURCE_DATE_EPOCH configuration | ||
|
|
||
| #### 6. Scala Upgrade Strategy Documentation | ||
| Comprehensive documentation of 5 paths to upgrade from Scala 2.11, addressing RoboVM constraints. | ||
|
|
||
| ## Files Changed | ||
| - `common-jvm/build.gradle` - Dependency update | ||
| - `build.gradle` - Repository cleanup | ||
| - `gradle/wrapper/gradle-wrapper.properties` - **Gradle 8.11.1 upgrade** | ||
| - `desktop/deploy/jpackage.cfg` - **JVM launch fix** | ||
| - `common-jvm/src/main/java/org/ergoplatform/uilogic/ergoauth/` - ErgoAuth feature | ||
| - `android/src/main/res/values/strings.xml` - String resources | ||
| - `ios/resources/i18n/strings.properties` - String resources | ||
| - F-Droid preparation files | ||
| - Documentation files | ||
|
|
||
| ## Testing Required | ||
| - ✅ Build succeeds | ||
| - ✅ No compilation errors | ||
| - ⏳ Build on Windows 11 with JDK 21 | ||
| - ⏳ Windows MSI installer with JVM fix (requires Windows environment) | ||
| - ⏳ ErgoAuth address generation with live dApp (requires dApp integration) | ||
|
|
||
| ## Impact | ||
| - **High Priority**: Java 21 build fix unblocks modern Java developers | ||
| - **High Priority**: Windows JVM launch fix unblocks all Windows desktop users | ||
| - **Medium Priority**: ErgoAuth feature improves dApp ecosystem UX | ||
| - **Low Priority**: F-Droid preparation expands distribution channels | ||
|
|
||
| ## Backward Compatibility | ||
| ✅ All changes are backward compatible | ||
| ✅ No breaking API changes | ||
| ✅ Existing features unchanged | ||
|

The PR title and description do not match the actual changes. The title claims "#issue75 Improve Password Authentication Performance on Low-End Devices", but the actual changes include:
- Gradle version upgrade (7.4 → 8.11.1)
- Database schema changes for multisig, hide_balance, and last_sync_time
- ErgoAuth address generation feature
- F-Droid preparation
- Multiple documentation files
Only a small portion of changes relate to password authentication performance. The PR should either:
- Be split into multiple focused PRs, or
- Have its title and description updated to accurately reflect all changes

Database migration issue: Migration version numbers are not sequential. MIGRATION_10_11, MIGRATION_11_12, and MIGRATION_12_13 jump from version 10 (current) to version 13. However, the database version is set to 13 directly. If any users are on an intermediate version between 10 and 13, the migration path is unclear. Consider whether all three migrations need to be separate or if they should be combined into a single MIGRATION_10_13.

Incorrect string formatting in Turkish translation. Lines 137-138 have malformed XML where the closing tag and opening tag for the next string are on the same line without proper separation. This will cause XML parsing errors. The lines should be:
Line 137: <string name="label_wallet_token_balance">%1$s tokens</string>
Line 138: <string name="label_last_sync">Son senkronizasyon: %1$s</string>

Same XML formatting issue as in Turkish translation. Lines 168-169 have malformed XML where closing and opening tags are on the same line. This will cause XML parsing errors.

The password dialog callback returns null immediately on line 130, but the actual error checking happens asynchronously in the coroutine. This breaks the existing contract where returning a non-null string indicates an error. The PasswordDialogFragment still expects a synchronous error return value (line 92-97 in PasswordDialogFragment.kt). This mismatch means the dialog won't handle immediate validation errors (like empty password) correctly.

Missing null check for password dialog reference. If the password dialog is dismissed or null when showProgress, showError, or dismissPasswordDialog are called, this will cause a NullPointerException. Add null safety checks before calling methods on passwordDialog.
This pull request addresses the issue of slow encryption and decryption operations during password authentication on low-end devices, such as the Moto G 4G. The changes ensure that these operations are performed on background threads, preventing UI hangs and improving the overall user experience.
Key Changes:
Android:
Moved encryption and decryption operations to background threads using Dispatchers.IO and lifecycleScope.
Added progress indicators to the PasswordDialogFragment to inform users of ongoing operations.
Disabled input fields and buttons during password verification to prevent duplicate actions.
Updated AbstractAuthenticationFragment to handle progress and error states during password authentication.
Desktop:
Refactored password verification to use coroutines (rememberCoroutineScope and Dispatchers.IO) for background processing.
Added a CircularProgressIndicator to the PasswordDialog to show progress during password verification.
Disabled Cancel/Done buttons while processing to ensure a smooth user experience.
UI Enhancements:
Added progress bars to both Android and Desktop password dialogs.
Improved user feedback by showing progress and error messages during authentication.
Performance Improvements:
Ensured that encryption/decryption operations no longer block the UI thread, even on low-end devices.
Reduced perceived delays by providing visual feedback during processing.
Impact:
Eliminates UI hangs during password authentication on low-end devices.
Provides a smoother and more responsive user experience.
Maintains compatibility with biometric authentication and other app features.
