Changelog

All notable changes to the "StackerFTP" extension will be documented in this file.

[1.2.21] - 2026-08-25

Fixed

  • Duplicate Cancel Button: Removed explicit Cancel action to prevent duplicate button with VS Code's native modal Cancel button.

[1.2.20] - 2026-08-25

Fixed

  • Cancelled State Reset: Automatically reset 'cancelled' flag and collision locks when starting a new transfer operation so subsequent uploads cleanly scan files and show overwrite dialogs as expected.

[1.2.19] - 2026-08-25

Fixed

  • Cancel / Escape Termination: Clicking Cancel or pressing Escape/closing the collision dialog now immediately aborts and clears all pending queue transfers instead of prompting repeatedly.
  • Modal Action Order: Prioritized 'Overwrite All' and 'Skip All' in modal dialog for seamless directory transfers.

[1.2.18] - 2026-08-25

Fixed

  • Permission & Overwrite Lifecycle: Cleaned collision decision state flow, added reset command (stackerftp.resetCollisionBehavior), and separated batch vs session overrides.
  • Skip All & Queue Visuals: Properly displayed skipped items with dedicated icons, eliminated false error states, and refined batch status summary.

[1.2.17] - 2026-08-25

Fixed

  • Skip All Handling: Fixed collision skip and skip-all logic to resolve gracefully as skipped items without throwing errors or triggering failure toasts.
  • Batch vs Session Overwrite Lifecycle: Ensured batch collision decisions (Overwrite All / Skip All) automatically reset at the end of each transfer operation while preserving session overrides.

[1.2.16] - 2026-08-25

Fixed

  • Duplicate Upload Execution: Fixed issue where explorer folder upload ran twice sequentially due to duplicate URI arguments passed by VS Code.
  • Batch vs Session Overwrite: Separated "Overwrite All" (applies only to current batch) from "Always Overwrite (Session)" (applies to whole session) and added stackerftp.overwriteBehavior configuration.
  • Transfer Queue Expand/Collapse Toggle: Fixed TreeView expand/collapse state caching issue with dynamic versioned IDs and consolidated duplicate toolbar buttons into a single toggle button.

[1.2.14] - 2026-08-24

Fixed

  • File Watcher Context Isolation: Fixed context path resolution in File Watcher to only monitor the target output directory (e.g. out) and ignore external source changes.
  • File Watcher Auto-Connect: Added automatic connection recovery on file system change events when the active SFTP/FTP session has timed out or disconnected.

[1.2.13] - 2026-08-24

Added

  • Hierarchical & Recursive Transfer Queue Tree: Added true multi-level folder and subfolder hierarchy in the Transfer Queue panel, organizing directory transfers into collapsible folder trees.
  • Per-Folder Progress Tracking: Displays live percentage, completed/total file counters, and byte transfer progress for each folder and subfolder branch.
  • Expand All / Collapse All in Transfer Queue: Added toolbar buttons (Expand All and Collapse All) with default collapsed state for a clean and minimalist transfer queue view.
  • Folder-Level Batch Cancel & Retry: Added ability to cancel or retry all transfers within a specific folder/subfolder branch with a single action.

[1.2.12] - 2026-08-24

Fixed

  • Ignore Pattern Matching: Enhanced matchesPattern with minimatch and prefix path matching so patterns like node_modules, .git, vendor or *.log properly match files in nested subdirectories.
  • Multi-Server Command Routing: Fixed deleteRemote, openRemoteFile, and download commands to use the target tree item's configuration and connection reference instead of falling back to default active server.
  • File Watcher Safety: Fixed autoDelete check in file watcher to require explicit autoDelete: true before deleting remote files, preventing accidental deletions when omitted.
  • Remote POSIX Path Normalization: Normalized remote root and target paths with path.posix.relative in getLocalPathFromRemote for robust cross-platform path resolution on Windows.
  • Remote Explorer Webview Context Support: Fixed file download and open actions in the Webview Remote Explorer to respect the configured local context directory.
  • Connection Manager State Cleanup: Cleaned up active connection key state on disconnect events.

[1.2.11] - 2026-08-24

Added

  • Local Context Path Support (context): Added full support for the context setting in sftp.json. Subdirectories (e.g. out, build, dist) can now be directly mapped to the remote root or custom remote paths.

Fixed

  • Context Path Mapping Across Operations: Fixed relative path calculation in upload, forceUpload, uploadProject, download, downloadProject, diff, uploadOnSave, file watcher, and quick search panel so files within the configured context folder upload/download without extraneous local folder prefixes on the remote server.
  • Remote to Local Path Resolution: Fixed downloads and diff inspections so remote files map back to the local context subfolder when configured.

[1.2.10] - 2026-03-26

Fixed

  • Config Resolution During Transfers: Fixed intermittent No SFTP configuration found errors by resolving the workspace from the selected item and reloading sftp.json when the in-memory config cache is empty.
  • SFTP Reconnect Stability: Fixed reconnect behavior after password-prompt logins by retaining runtime credentials in memory for later reconnect attempts.
  • Connection State Cleanup: Improved SFTP close/end handling and keepalive settings so dropped sessions are cleaned up consistently before reconnecting.

[1.2.9] - 2026-03-26

Fixed

  • SCM Multi-Select Upload: Fixed Source Control Changes context-menu uploads so all selected files are uploaded instead of only the active item.
  • SCM Multi-Select Download: Fixed the matching download path for Source Control multi-selection so all selected files are processed consistently.

[1.2.8] - 2026-03-18

Changed

  • Release Audit: Reviewed command and menu coverage to verify contributed actions are registered and wired correctly before the next implementation round.

Fixed

  • Profile Management: Implemented the Edit Profiles flow in the config command so profiles can now be created, edited, deleted, and assigned as the default profile without hand-editing JSON.
  • Select All Command: Wired stackerftp.selectAllFiles to the native tree selection flow so it now selects all visible items in the Remote Explorer tree.

[1.2.7] - 2026-03-18

Fixed

  • Recursive Remote Directory Creation: Fixed SFTP uploads failing with No such file when intermediate remote folders do not exist. Upload, create file, duplicate/write, rename, and direct mkdir flows now create missing parent directories consistently.
  • FTP Remote Path Safety: Fixed FTP remote directory creation and path checks so they no longer change the active working directory unexpectedly during upload/stat operations.
  • FTP Transfer Stability: Serialized FTP upload/download operations on a single connection to prevent client state races during directory creation and path checks.
  • Watcher Remote Delete Handling: Fixed file watcher auto-delete logic to detect remote files vs folders correctly and use recursive directory removal when needed.

[1.2.6] - 2026-03-17

Fixed

  • Upload to Non-Existing Folders: Fixed upload failures when parent directory doesn't exist on the server. Now all upload methods automatically create the parent directory structure before uploading files.
    • ftpConnection.upload() - file upload now creates parent directories
    • sftpConnection.upload() - file upload now creates parent directories
    • ftpConnection.writeFile() - file creation now creates parent directories
    • sftpConnection.writeFile() - file creation now creates parent directories
  • Affected Operations: Single file upload, folder upload, sync to remote, copy to other remote, sync between remotes, git changed files upload, project upload, webview file create, new file, duplicate file

[1.2.5] - 2026-02-25

Fixed

  • Download Single File: Fixed issue where downloading a single file was downloading the entire project instead of just the selected file.
  • Multiple Selection: Added support for selecting multiple files/folders for upload, download, and delete operations across all panels.
  • Upload Folders: Fixed issue where folders weren't being uploaded in multiple selection mode.
  • Source Control Upload: Fixed upload from Source Control sidebar to handle multiple selected files correctly.
  • Remote Explorer Tree: Added multi-select support for delete and download operations.
  • VS Code Explorer: Added download button for folders (was only available for files).

Fixed

  • WebView Download: Fixed folder download - now correctly uses downloadDirectory instead of treating folders as files.
  • Delete Confirmation: Fixed delete dialog showing only one item name when multiple items are selected.

[1.2.4] - 2026-02-19

Fixed

  • Folder Transfer UX: Added immediate feedback when Upload Folder or Download Folder starts, so users see that the command is running during initial scan/queue preparation.
  • Progress Visibility: Added notification progress states (Connecting..., Scanning and queueing files...) for folder upload/download operations.

[1.2.3] - 2026-02-19

Fixed

  • Download Stall Protection: Added transfer timeout safeguard so stalled downloads no longer block the queue indefinitely.
  • Queue Recovery: Timed-out transfer connections are now safely dropped from pool reuse to prevent repeated stuck Pending items.

[1.2.2] - 2026-02-19
