Replace global log_* wrapper functions with create_module_logger(__name__)
instances across the codebase, enabling proper module-level logger
namespacing. Simplifies core/log_system/log_funcs.py by removing legacy
_normalize_module_path and cleaning up _normalize_module_name. Bumps
log_system config to 2.0.0 and introduces PROJECT_ALIASES for cleaner
log module prefix stripping.

- Track aria2 daemon state (managed/running/version/active_transfers) in get_aria2_status
- Implement idle auto-stop timer (5 minutes) with aria2_auto_stop_daemon setting
- Add start_aria2_daemon() and stop_aria2_daemon() helpers in core/downloader.py
- Migrate legacy release-* install directories to normalized versioned paths

- Add core/downloader.py: build_download_headers for consistent User-Agent,
Accept, and CivitAI-specific Referer/Origin headers across download backends
- Resolve CivitAI API redirects before handing URLs to aria2
- Strip sensitive URL parameters from download logs
- Forward civitai_session_token from the frontend to the downloader
Integrates aria2c as an alternative download backend alongside the built-in
Python downloader. Adds settings for selecting the backend and configuring
the aria2c executable path, plus a status check button in the options panel.
Backend changes:
- core/downloader.py: aria2 daemon lifecycle, JSON-RPC client, pause/resume
state machine, and transfer tracking
- core/settings.py: download_backend normalization and aria2c_path setting
- __init__.py: new API routes for pause, resume, and aria2 status checks
Frontend changes:
- options_methods.js: backend selector, aria2c path input, check button,
and local storage persistence
- resolve_download_methods.js: pause/resume handlers, pending status
transitions, and progress rendering for aria2 downloads
- queue_methods.js: queue panel pause/resume buttons, backend badge, and
debounced panel updates
- search_panel.js: actionsHtml support for composite action buttons
Replace CivitAI-only search with a multi-source metadata resolution route using
SHA256 exact-match validation, dead-link filtering, and live download URL
probing. Unify sidecar metadata saving across all remote sources. Add
force-refresh support, local metadata import with preview detection, and
frontend source-aware UI controls.
- Add get_comfy_root_path() to core/path_utils.py and use it in __init__.py and core/downloader.py instead of inline logic
- Add select_primary_model_file(), parse_size_to_bytes(), get_version_sort_key(), and check_credential_http() to core/type_utils.py
- Replace duplicated credential-check helpers in civitai.py, huggingface.py with check_credential_http()
- Replace duplicated size parsing and version sorting in civarchive.py, civitai.py with shared utilities
- Replace duplicated primary-file selection in civarchive.py, civitai.py, lora_manager_archive.py with select_primary_model_file()
- Replace inline tempfile-based JSON writes in popular.py with write_json_atomic()
- Remove dead reload_model_list() from model_list.py
- Fix workflow_analyzer.py hint prioritization for diffusion_models vs specific output hints
- Add first_non_empty() and to_int() to core/type_utils.py
- Add get_filename_from_path() and METADATA_DIR to core/path_utils.py
- Replace inline implementations across resolver, downloader, and sources
with calls to the shared utilities
- Move strip_known_model_extension from resolver to matcher
Add core/type_utils.py with as_dict/as_list helpers, and
core/progress.py with a unified report_progress() callback.
Replace inline duplicated implementations of _json_safe_metadata(),
_as_list(), normalize_filename(), and per-source _report_progress()
with calls to the shared modules across downloader, matcher, resolver,
and all source modules (CivitAI, CivArchive, HuggingFace, LoRA Manager).
Extend filename normalization to include dots as separators.
Extract repeated path normalization and identity logic from __init__.py,
core/resolver.py, core/downloader.py, and core/scanner.py into a shared
core/path_utils module. Also add a loading state to the local model picker
so it waits for models to load before rendering options.
core/downloader.py: When a file already exists at dest_path, extract the expected
SHA256 from metadata, prefers a trusted LoRA Manager sidecar hash, falls back to
calculating the file hash, and returns already_exists=true plus sha256_source
when the hashes match. If the hashes differ, the download is skipped with a
clear warning instead of silently re-downloading.
web/resolver/actions/resolve_download_methods.js: Thread already_exists through
resolveDownloadMethods so notifications, progress messages, and snapshot payloads
reflect 'Already downloaded' when the backend determined the model was a SHA256
match.
Add support for additional ComfyUI model types including diffusers, gligen,
style models (latent/regular upscale), audio encoders, background removal,
frame interpolation, geometry estimation, detection, model patches/photomaker,
and optical flow models.
Backend changes:
- Extend CATEGORY_MAP, URN_TYPE_MAP, and node type hints in workflow analyzer
to cover dozens of new loader node types and singular/plural aliases.
- Add MODEL_OUTPUT_TYPE_TO_CATEGORY and get_node_output_category_hint() so
loader output types can contribute category hints.
- Make widget name matching normalize underscores, hyphens, and spaces.
- Improve directory discovery to enumerate folders from folder_paths while
filtering unsupported categories.
- Include folders as model entries in directory scanning (with a diffusers
guard requiring model_index.json).
Frontend changes:
- Update download target category maps, display names, token name maps, and
per-node widget index lists to match the expanded backend coverage.
Implements a new download path configuration UI and backend logic:
- Add Subfolder fill mode: Suggested (existing), Template, Manual
- Add Base Model Path Mappings to override detected base-model folders
- Add Default Root settings to control root directory per category
- Add Detect From Existing Folders button that infers templates and mappings from local model folders
- Add backend /model_resolver/root-directories and /model_resolver/path-template-suggestions routes
- Refactor resolver settings into core/settings.py for shared frontend/backend use
- Extract path template inference logic into core/path_templates.py
- Update download panel, context menu, and loading flow to use new path settings
Add a shared normalize_download_category helper (with CATEGORY_MAP) in Python
and use it in get_download_directory to prefer redirected paths and to rank
diffusion_models above legacy unet folders. Mirror the same normalization in
the JS downloadTargetMethods, applying it consistently when coalescing
downloadDirectories, building dropdown keys, and reading/writing selections.
Also fix display labels to use 'diffusion_models' instead of 'unet'.
Propagate the resolved download directory and file path from the backend
download flow into frontend progress UI: add \path\ and \directory\ fields
to download progress state, render right-clickable context menu entries on
progress bars and status messages, and allow opening the download folder
directly from completion or error notifications. Also update the HuggingFace
author index.
Replace all link dialog terminology with resolver terminology
throughout the codebase, including module names, CSS classes,
IDs, JS variables, SVG gradient IDs, and log module names.
Remove the old web/linker/ tree and introduce the new web/resolver/
tree with parallel structure. Also replace core/linker.py with
core/resolver.py.
Include base_model and tags in civitai search/resolve results and model lookup responses. Add a new /model_linker/subfolders API route that uses ComfyUI folder_paths to return known subfolder paths for a given category. Improve downloader.get_download_directory to choose a preferred path (preferring paths outside the ComfyUI install) and add robust path normalization/commonpath checks. On the frontend, add download target controls (folder + optional subfolder) with styling, loading of download directories/subfolders, autocomplete and selection logic, heuristics to suggest civitai subfolders (particularly for loras), and integrate the chosen category/subfolder into the download payload and UI wiring.
Replace direct uses of the logging module and module-level loggers with the centralized log_system.log_funcs (log_debug/log_info/log_warn/log_error/log_exception) across multiple modules. Updated imports and removed unused logging.getLogger() instances in downloader, scanner, sources (civitai, huggingface, model_list, popular), workflow_analyzer, workflow_updater, and __init__.py. Minor message/text tweaks and import formatting applied; behavior unchanged aside from routing logs through the shared logging helpers.
Introduce a new logging subsystem under core/log_system (logger.py, config.py, log_funcs.py) implementing AzLogs (LogLevel enum, colored console output, optional file rotation) and a lightweight wrapper (log_debug/info/warn/error/exception) with safe fallback when AzLogs is unavailable. Integrate these log functions across many core modules (downloader, linker, matcher, scanner, workflow_analyzer, workflow_updater, sources and related files) and export logger and helper log functions from core.__init__. Replace several direct logging calls in linker with the new log_* helpers and update core.__init__ exports. Also include small code style and robustness tweaks (path/filename normalization, JSON/file handling, minor refactors and formatting fixes) to improve matching and model-list/popular lookups.
Refactor and harden the Model Linker extension: normalize string quoting/formatting and improve logging and error responses across API routes. Make route registration more robust to missing PromptServer and dependencies. Add/expand download-related features: safer request parsing (including is_urn handling), CivitAI URN support & direct download URL resolution, popular/model-list/HuggingFace/CivitAI search fallbacks, improved header handling for HF/CivitAI, and better category/directory mapping. Improve downloader reliability and UX: folder_paths fallback, pre-initialize download progress entries, smoother speed calculation and CLI logging, cancellation cleanup on Windows, stronger exception handling, and consistent JSON responses from endpoints.
