v1.0.28: fix sync rewrite/delete loop, Avast-inspired icon

Sync loop root-cause fixes (three independent bugs): 1. Folder change clears stale file states (AddPairViewModel): when localPath or remotePath changes on an existing pair, all SyncFileStateEntity records are wiped. Previously those stale records caused every sync to attempt DELETE_REMOTE on the old folder's files and to treat all new-folder files as changed — causing both the "deleting 32 files" loop and rewrites on every run. 2. Download stores null localModifiedAt (SyncEngine): SAF document cursors can return a stale mtime immediately after a write. Storing null forces the SKIP reconciliation pass on the next sync to read the actual walkFiles cursor value, breaking the download->changed-> download loop caused by mtime inconsistency. 3. Second-precision mtime comparison (syncDecide): WebDAV RFC-1123 has 1-second precision; FAT32 has 2-second precision. Comparing at millisecond level caused phantom "changed" detections after syncing to/from these systems. Now uses epochSecond for both local and remote. Icon: three bold teal/red/yellow teardrop streaks (Avast palette) flying into a white cloud centre, on dark charcoal background. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

amir	34fb06a673	v1.0.28: fix sync rewrite/delete loop, Avast-inspired icon Sync loop root-cause fixes (three independent bugs): 1. Folder change clears stale file states (AddPairViewModel): when localPath or remotePath changes on an existing pair, all SyncFileStateEntity records are wiped. Previously those stale records caused every sync to attempt DELETE_REMOTE on the old folder's files and to treat all new-folder files as changed — causing both the "deleting 32 files" loop and rewrites on every run. 2. Download stores null localModifiedAt (SyncEngine): SAF document cursors can return a stale mtime immediately after a write. Storing null forces the SKIP reconciliation pass on the next sync to read the actual walkFiles cursor value, breaking the download->changed-> download loop caused by mtime inconsistency. 3. Second-precision mtime comparison (syncDecide): WebDAV RFC-1123 has 1-second precision; FAT32 has 2-second precision. Comparing at millisecond level caused phantom "changed" detections after syncing to/from these systems. Now uses epochSecond for both local and remote. Icon: three bold teal/red/yellow teardrop streaks (Avast palette) flying into a white cloud centre, on dark charcoal background.

amir	dc2a0b2c68	v1.0.27: knot-inspired icon, fix media-not-found on photo open Icon: two thick tube-style arcs with 3D glossy highlights. Arc 1 (left side): coral #E8665A to orange #E8A040 Arc 2 (right side): steel blue #4A7FD4 to deep purple #7B5EA7 Arrowheads: orange and purple. Background: dark purple-black. Inspired by the braided knot color palette. Fix "media not found" when opening photos: - Intent now sets ClipData alongside FLAG_GRANT_READ_URI_PERMISSION so the permission correctly propagates through the system chooser to whichever app the user picks. - openFile() and downloadToCache() both call MediaScannerConnection so newly synced/downloaded files appear in gallery MediaStore index before the viewer launches.

amir	742f634084	v1.0.26: fix multi-selection reactivity, redesign icon, security review Fix multi-selection: selectedKeys exposed as StateFlow, collected in FilesScreen so checkboxes and highlights update correctly on every tap. fileKey() made public so UI can check membership without ViewModel calls. Icon: white cloud body with two cyan/teal circular sync arcs (AutoSync style), deep blue-to-teal gradient background. Security review clean: no hardcoded credentials, cleartext blocked by network_security_config, allowBackup=false, path traversal guards in place on both server responses and local resolution.

amir	8fdd22bc98	v1.0.25: multi-select files, unified notification, dark theme, icon redesign - FilesScreen: long-press enters selection mode, bulk share/delete toolbar, BackHandler - FilesViewModel: ShareMultiple action, isSelectionMode/selectedCount state, download-to-cache for open/share - FileWatchService: recursive FileObserver per subdirectory; unified notification updated with sync result via WorkManager flow observation - SyncWorker: silent flag suppresses notifications when triggered by watcher; emits KEY_RESULT_SUMMARY output data - Passbolt-inspired dark theme (Red700/Red500 primary, near-black surface) - App icon: circular AutoSync-style sync arrows (cyan gradient, deep navy background) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-25 02:22:43 +00:00
amir	146b8baf9a	v1.0.24: harmonious icon, recursive file watching, download-then-open, security fixes Icon: three identical parallel arcing arrows (same bezier curve, same blue-to-teal gradient #64C8FF→#32EDBB, same arrowhead geometry) — visually cohesive and clearly visible against the near-black background. FileWatchService: FileObserver is now recursive — watchDirRecursive() creates an observer for each subdirectory at startup, and adds new watchers when CREATE events produce new directories. Fixes files added to subdirectories not being detected. FilesViewModel: openFile/shareFile now fall back to download-then-open when the file is absent locally. AccountRepository + ProviderFactory injected; downloads to context.cacheDir/syncflow_open/ with isDownloading state. Path traversal guard added (reject relativePath containing ".."). file_paths.xml gains cache-path entry. WebDavProvider: path-traversal guard in parsePropfind — skip any server-returned filename containing "..", "/" or "\". Replace android.util.Log with Timber so debug logs are stripped from release builds. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-25 00:37:16 +00:00
amir	08dc4f5bd4	v1.0.23: functional Files tab, background service persistence, startup indexer, curved icon - FilesScreen: per-file context menu (Open, Share, Rename, Delete), rename dialog, delete confirmation, FileProvider-based open/share intents, Snackbar error feedback - FilesViewModel: FileAction sealed class + SharedFlow; openFile, shareFile, deleteFile, renameFile with DB cleanup; resolveFile handles SAF primary: URIs - FileWatchService: stopWithTask=false keeps watcher alive after app swipe-away; catchupScan on startup detects changes missed while service was not running; SyncFileStateDao injected; FileObserver used for real-path SAF URIs - BootReceiver: handles MY_PACKAGE_REPLACED to restart service after app update - file_paths.xml: added external-path so FileProvider can serve /storage/emulated/0 files - ic_launcher_foreground: three curved stroke-based arrows (quadratic bezier, round caps) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-24 23:25:58 +00:00
