From d8c55ff280f03c972460d93199a87a52e7443bba Mon Sep 17 00:00:00 2001 From: xAstroBoy <307941036+xAstroBoy@users.noreply.github.com> Date: Mon, 20 Jul 2026 00:09:53 +0200 Subject: [PATCH 1/6] Add SFTP fast path for OBB transfers + fix ADB disconnect flash SFTP fast transfers (rooted headsets running an SSH server): - SFTP.cs: detects root (su -> uid=0), probes for an SSH server on the headset (ports 22/8022/2222), authenticates via key or password, and verifies the OBB dir is visible before use. Uploads OBBs over SFTP with the same progress/ETA UI as adb push, and transparently falls back to adb push when SFTP is unavailable or fails. - Uses /storage/emulated/0/Android/obb (canonical) with /sdcard fallback. - Titlebar shows Root and SFTP status after connect. - SftpCredentialsForm: prompts for username + password and/or key file when a server is found but stored credentials do not authenticate. - SFTP settings persisted in SettingsManager (host/port/user/pass/key). ADB device detection: - GetDevicesResilient() retries across an adb daemon restart so a version-mismatch server bounce (e.g. a different-version adb in PATH killing/restarting the server) no longer flashes "No Device Connected". Measured on wireless (Quest 3, same link): SFTP ~50 MB/s vs adb push ~28 MB/s for a 200 MB payload, verified byte-identical (md5). --- ADB.cs | 81 ++++++ AndroidSideloader.csproj | 34 +++ MainForm.cs | 42 +++- SFTP.cs | 471 +++++++++++++++++++++++++++++++++++ SftpCredentialsForm.cs | 186 ++++++++++++++ Utilities/SettingsManager.cs | 16 ++ packages.config | 10 + 7 files changed, 837 insertions(+), 3 deletions(-) create mode 100644 SFTP.cs create mode 100644 SftpCredentialsForm.cs diff --git a/ADB.cs b/ADB.cs index 75be4092..75bca7a8 100644 --- a/ADB.cs +++ b/ADB.cs @@ -172,6 +172,78 @@ public static ProcessOutput RunAdbCommandToString(string command, bool suppressL } } + // Returns true if the `adb devices` output lists at least one usable device. + private static bool HasOnlineDevice(string devicesOutput) + { + if (string.IsNullOrEmpty(devicesOutput)) + { + return false; + } + + string[] lines = devicesOutput.Split('\n'); + for (int i = 1; i < lines.Length; i++) + { + string line = lines[i].Trim(); + if (line.Length == 0) + { + continue; + } + if (line.IndexOf("List of devices", StringComparison.OrdinalIgnoreCase) >= 0) + { + continue; + } + if (line.IndexOf("unauthorized", StringComparison.OrdinalIgnoreCase) >= 0 + || line.IndexOf("offline", StringComparison.OrdinalIgnoreCase) >= 0) + { + continue; + } + if (line.IndexOf("device", StringComparison.OrdinalIgnoreCase) >= 0) + { + return true; + } + } + return false; + } + + // `adb devices` briefly reports nothing while the daemon is (re)starting - which + // happens whenever a different-version adb client (e.g. one in PATH) forces the + // server to kill and restart.

SingleThreadMode still forces a single stream when enabled. SFTP OBB transfers: - CopyObbCore now uploads multiple OBB files in parallel, one SFTP connection per worker (SSH.NET clients are not safe to share). Remote directories are pre-created once up front to avoid races, and files are distributed across workers greedily by size for balanced connections. Transfer speed display: - OBB copies now report live throughput (MB/s) in the status line for both the SFTP fast path and the adb push fallback, matching downloads. Reliability: - UpdateQuestInfoPanel ran its adb shell calls (getprop/df) on the UI thread; a slow or mid-restart adb daemon would freeze the whole window. Those calls now run off the UI thread.

Large transfers and on-device backup/restore/install prompts are exempt so they are never force-killed. Timed reads use async stdout/stderr, which also removes a latent sequential-ReadToEnd deadlock. A timeoutMs override was added. Startup: - Stop hard-killing every adb.exe on launch. That tore down a running adb server and dropped any active wireless (adb connect) session, forcing a reconnect that often failed silently. start-server reuses a compatible running server, preserving the connected device.

Successful rows auto-clear; failed rows stay with a right-click Retry / Remove / Clear finished menu. Never hang (the softlock fix): - Each SFTP upload now uses a 60s OperationTimeout, so a wedged channel throws instead of blocking UploadFile forever. A single stuck file could previously freeze an entire multi-hundred-file OBB upload; it can't anymore. Auto-retry + verify: - Each file is retried up to 3x on a fresh reconnection with backoff. - After every upload the remote path is stat'd and checked for exact size; a file that isn't actually there (or is truncated) is treated as a failure and retried, never reported as done. Failure isolation: - One bad file no longer aborts the batch. Files that still fail after retries are left Failed in the strip with a per-file Retry action (SFTP.RetryUpload), instead of re-pushing the whole set. Only a total failure falls back to adb push. --- AndroidSideloader.csproj | 4 +- MainForm.cs | 6 + SFTP.cs | 211 ++++++++++++++++++++------ TransferQueue.cs | 36 ++++- TransferWindow.cs => TransferStrip.cs | 206 ++++++++++++++----------- 5 files changed, 327 insertions(+), 136 deletions(-) rename TransferWindow.cs => TransferStrip.cs (53%) diff --git a/AndroidSideloader.csproj b/AndroidSideloader.csproj index 9accf475..74c01f2d 100644 --- a/AndroidSideloader.csproj +++ b/AndroidSideloader.csproj @@ -313,8 +313,8 @@ - - Form + + Component diff --git a/MainForm.cs b/MainForm.cs index 971f107c..6516b9de 100755 --- a/MainForm.cs +++ b/MainForm.cs @@ -91,6 +91,7 @@ public partial class MainForm : Form private const int TILE_SPACING = 10; private string freeSpaceText = ""; private string freeSpaceTextDetailed = ""; + private TransferStrip _transferStrip; private int _questStorageProgress = 0; private Color _mirrorPillColor = Color.FromArgb(32, 36, 44); private DateTime _mirrorMenuClosedAt = DateTime.MinValue; @@ -467,6 +468,11 @@ private async void Form1_Load(object sender, EventArgs e) speedLabel.Text = String.Empty; diskLabel.Text = String.Empty; + // Integrated transfer strip: overlays the bottom of the games list while files + // are moving (SFTP / push), themed to match the list, and hides itself when idle. + _transferStrip = new TransferStrip(gamesListView.BackColor, gamesListView.ForeColor); + _transferStrip.AttachTo(this, gamesListView); + settings.MainDir = Environment.CurrentDirectory; settings.Save(); diff --git a/SFTP.cs b/SFTP.cs index c3f5382a..e2ccf5d3 100644 --- a/SFTP.cs +++ b/SFTP.cs @@ -465,76 +465,120 @@ private static ProcessOutput CopyObbCore( } }; - Exception workerError = null; + int failedCount = 0; + Exception lastError = null; List workers = new List(); for (int w = 0; w < degree; w++) { workers.Add(Task.Run(() => { + SftpClient sftp = null; try { - using (SftpClient sftp = new SftpClient(BuildConnectionInfo(Host, Port))) + while (workQueue.TryDequeue(out string file)) { - sftp.Connect(); - sftp.BufferSize = TransferBufferSize; - - while (workQueue.TryDequeue(out string file)) + string remoteFilePath = remoteFiles[file]; + string fileName = Path.GetFileName(file); + TransferItem item = transferItems[file]; + long fileTotal = new FileInfo(file).Length; + + bool ok = false; + Exception fileError = null; + for (int attempt = 0; attempt < 3 && !ok; attempt++) { - string remoteFilePath = remoteFiles[file]; - string fileName = Path.GetFileName(file); - TransferItem item = transferItems[file]; - long fileTotal = new FileInfo(file).Length; - DateTime fileStart = DateTime.UtcNow; + long fileCounted = 0; long lastUploaded = 0; - - TransferQueue.SetState(item, TransferState.Active); - - using (FileStream stream = File.OpenRead(file)) + DateTime fileStart = DateTime.UtcNow; + try { - sftp.UploadFile(stream, remoteFilePath, true, uploaded => + if (sftp == null || !sftp.IsConnected) + { + try { sftp?.Dispose(); } catch { } + sftp = new SftpClient(BuildConnectionInfo(Host, Port)); + // A wedged channel makes each SFTP write request time out and + // throw instead of blocking UploadFile forever (the softlock). + sftp.OperationTimeout = TimeSpan.FromSeconds(60); + sftp.Connect(); + sftp.BufferSize = TransferBufferSize; + } + + TransferQueue.SetState(item, TransferState.Active); + TransferQueue.Report(item, 0, 0); + + using (FileStream stream = File.OpenRead(file)) { - long u = (long)uploaded; - long delta = u - lastUploaded; - lastUploaded = u; - if (delta != 0) + sftp.UploadFile(stream, remoteFilePath, true, uploaded => { - Interlocked.Add(ref transferredBytes, delta); - } - double fe = (DateTime.UtcNow - fileStart).TotalSeconds; - double fileMBps = fe > 0.1 ?
