[Unreleased]

[1.3.0] - 2026-06-02

Added

HTTP Runner Protocol Hardening

Expanded the Go generic HTTP runner to support chained prerequests, shared cookie sessions, relative endpoint resolution, and header/form/body template substitution.
Added richer extraction support for JSON arrays, nested paths, HTML selectors, regex selectors, attribute extraction, response templates, and URL templates.
Added sidecar request IDs so Python only resolves upload responses from the matching Go event instead of accepting stale or unrelated output.

Imgur Sidecar Integration

Added an Imgur HTTP request builder so Imgur uploads can use the same validated Python-to-Go sidecar workflow as the other active services.
Added tests for missing Imgur credentials and generated request shape.

Changed

Normalized per-service worker counts so configured thread values are consistently clamped and forwarded into upload jobs.
Moved Python coverage settings into .coveragerc and kept pytest configuration focused on test discovery and runtime behavior.
Updated Windows and Unix build scripts to rely on go mod download for reproducible builds without rewriting module metadata.
Refreshed release metadata, build banners, documentation links, and download artifact names for v1.3.0.

Security

Updated Go security-sensitive dependencies, including golang.org/x/image, golang.org/x/net, and golang.org/x/sys.
Tightened GitHub security scanning by making govulncheck, gosec, pip-audit, and medium-or-higher Bandit findings fail the workflow.
Added pip-audit==2.10.0 and bandit[sarif]==1.9.4 to the pinned Python dependency set.
Documented the ViperGirls legacy MD5 value as a protocol-required compatibility hash, not a security credential.

Fixed

Ensured sidecar response correlation does not cross wires when multiple uploads are active.
Ensured HTTP response bodies are closed explicitly in service code and test paths.
Preserved compatibility helpers while silencing false-positive unused warnings in strict Go linting.

[1.2.4] - 2026-05-20

Fixed

Packaged Executable Startup

Updated tkinterdnd2 to 0.4.3 so PyInstaller builds no longer crash while importing the removed legacy tkinter.tix module path.
Kept drag-and-drop support bundled through the existing PyInstaller --collect-all tkinterdnd2 flow.

Cross-Platform Test Reliability

Normalized Windows short-path and macOS /private/var path assertions in the Python test suite.
Mocked GUI success dialogs in menu removal tests so headless Windows/macOS CI runs do not stall.
Aligned validation expectations for safe filename fallbacks, dangerous characters, and thread-count limits.

Security

Updated Pillow to 12.2.0 for the latest image-processing security fixes.
Replaced Safety dependency scanning with pip-audit==2.10.0 in CI and security workflows.

Changed

Pinned flake8==7.1.1 for stable lint output in CI.
Refreshed release documentation, download links, and tag examples for v1.2.4.

[1.2.3] - 2026-01-31

🐛 Bug Fixes

Gallery Creation Logic Fix

Fixed critical issues with IMX inline gallery creation in the Go sidecar.

1. IMX Login State Tracking

Problem: IMX login was not being tracked across requests, causing gallery creation to fail
Root Cause: No persistent state for IMX login status
Fix: Added imxState struct with mutex-protected isLoggedIn flag
- Login state now persists across requests
- Prevents redundant login attempts

2. Correct Form Field Names

Problem: IMX login was using incorrect form field names
Root Cause: Field names didn't match the actual login form
Fix: Updated to use correct field names: usr_email, pwd, doLogin, remember

3. URL Domain Fix

Problem: Using www.imx.to caused certificate issues and cookie mismatches
Root Cause: Certificate is valid for imx.to but not www.imx.to
Fix: Updated all IMX URLs to use naked domain https://imx.to/
- Ensures cookies are properly shared between login and gallery operations
- Added proper Referer headers for security validation

4. Gallery ID Extraction

Problem: Gallery ID extraction failed when redirect didn't include query params
Fix: Added fallback body parsing to find gallery ID in response HTML
- Looks for manage?id= links in the response
- Provides detailed debug logging for troubleshooting

Files Changed:

uploader.go: Updated IMX login and gallery creation logic

[1.2.2] - 2026-01-22

🐛 Bug Fixes

Batch Upload Stability Improvements

Fixed 5 critical issues discovered during large batch upload testing (1141 files across 34 folders).

1. Worker Count Setting Not Respected

Problem: Changing Worker Count in UI had no effect - uploads always used 8 workers regardless of setting
Root Cause: Sidecar process only started once at initialization; UI setting changes didn't restart it
Fix: Added automatic sidecar restart when worker count changes
- SidecarBridge.set_worker_count() now detects changes and restarts sidecar
- start_upload() applies current worker count before each upload
- Graceful restart with timeout handling

2. File Reading Stalling with Large Batches

Problem: Reading stalled at 500 of 1141 files; "Already read" message but files not visible in UI
Root Cause: UI queue backlog with large batches + thumbnail generation delays
Fix: Enhanced queue handling and user feedback
- Added 5-second timeout to UI queue operations
- Fallback: files added without thumbnails if queue is full
- "Loading thumbnails..." message for batches > 100 files
- Queue size monitoring with debug logging

3. Program Hanging on Close

Problem: Program hung for ~20 seconds when trying to close during thumbnail generation
Root Cause: thumb_executor.shutdown(wait=True) waited indefinitely for all tasks
Fix: Changed to non-blocking shutdown
- shutdown(wait=False, cancel_futures=True) cancels pending tasks
- 300ms grace period for current tasks to finish
- Program now closes in <1 second

4. Bottom Progress Bar Not Updating

Problem: Progress bar stayed at 0% until all uploads finished, then jumped to 100%
Fix: Added real-time progress calculation
- Updates every time a file completes: progress = upload_count / upload_total
- Live feedback as files complete

5. "Open Output Folder" Button Not Working

Problem: Button did nothing after upload completion or after clearing list
Fix: Added comprehensive error handling
- Try/catch around os.startfile() and subprocess.run()
- Clear error messages if folder can't be opened
- Button properly disabled when list is cleared
- Info message if no output files exist

🏗️ Build System

Release Workflow Improvements

[1.2.1] - 2026-01-18

🐛 Bug Fixes

Critical Gallery Creation Fix

Fixed a critical bug in the IMX plugin where the "One Gallery Per Folder" feature failed to create individual galleries per batch when a manual gallery ID was present in the config.

Issue Details

Problem: When users enabled "One Gallery Per Folder" but had a gallery ID from a previous session in the optional field, all images from all batches were incorrectly uploaded to the same gallery instead of creating individual galleries per batch.
Root Cause: The prepare_group() method in modules/plugins/imx.py checked for a manual gallery_id BEFORE checking if auto_gallery was enabled, causing early return without creating new galleries.
Impact: Multi-folder uploads with auto-gallery enabled would fail to organize images into separate galleries.

Fix Implementation

Reordered logic in ImxPlugin.prepare_group() to check auto_gallery setting FIRST
Now matches the correct behavior already implemented in Pixhost plugin
Enhanced docstrings and logging messages for better clarity

New Behavior

✅ If auto_gallery is ENABLED: Creates a new gallery for each batch (ignores manual gallery_id)
✅ If auto_gallery is DISABLED: Uses manual gallery_id if specified, otherwise no gallery
✅ Consistent behavior across all plugins (IMX, Pixhost, etc.)

Testing

Verified all logic paths with comprehensive verification tests
Confirmed correct behavior for all setting combinations
Validated consistency with Pixhost plugin implementation

Files Changed:

modules/plugins/imx.py: Fixed prepare_group() logic (lines 139-177)

Commit: e6a1cb0 - fix: Correct IMX gallery creation logic to respect auto_gallery setting

Complete Graceful Shutdown System (2026-01-13)

A comprehensive two-layer graceful shutdown implementation for both application and sidecar:

Go Sidecar Layer (uploader.go):

Signal Handling: Listen for SIGINT and SIGTERM OS signals
Worker Management: sync.WaitGroup tracks all worker goroutines
Coordinated Shutdown:
- Stop accepting new jobs immediately on shutdown signal
- Close job queue to signal workers
- Wait for all in-flight jobs to complete
- Clean resource cleanup and logging
EOF Handling: Gracefully handle stdin closure (normal termination)

Python Application Layer (main.py, modules/ui/main_window.py, modules/sidecar.py):

Window close event handling via WM_DELETE_WINDOW protocol handler
File > Exit menu performs graceful shutdown
Signal handlers for SIGINT (Ctrl+C) and SIGTERM in main.py
Component-level shutdown methods:
- AutoPoster.stop() - Stops forum posting thread with 3-second timeout
- RenameWorker.stop() - Stops gallery rename worker with 2-second timeout
- UploadManager.shutdown() - Unregisters event listeners and cleans up threads
- SidecarBridge.shutdown() - Gracefully terminates Go sidecar process
  - Closes stdin to signal exit
  - Waits 5 seconds for graceful termination
  - Force kills if necessary (SIGTERM → SIGKILL)
Upload cancellation - In-progress uploads stopped cleanly via cancel_event
ThreadPoolExecutor cleanup - Thumbnail executor properly shut down
Resource cleanup:
- All background threads properly joined with timeouts
- Event queues unregistered from sidecar bridge
- Go subprocess terminated cleanly
- Log window closed if open

Combined Benefits:

No job loss during shutdown from either application exit or system signal
Uploads complete before exit
Container and systemd friendly
No orphaned goroutines or threads
Clean exit codes
Fast exit (worst case ~12 seconds with all timeouts)
Prevents resource leaks (threads, processes, file handles)
Ensures data integrity (no partial writes)
Cross-platform support (Windows, Linux, macOS)

🔧 Fixed
