feat(deps): add unified dependency resolver using uv pip compile
- Add UnifiedDepResolver module with 7 FRs: collect, compile, install pipeline - Integrate startup batch resolution in prestartup_script.py (module scope) - Skip per-node pip install in execute_install_script() when unified mode active - Add use_unified_resolver config flag following use_uv pattern - Input sanitization: reject -r, -e, --find-links, @ file://, path separators - Handle --index-url/--extra-index-url separation with credential redaction - Fallback to per-node pip on resolver failure or uv unavailability - Add 98 unit tests across 20 test classes - Add PRD and Design docs with cm_global integration marked as DEFERRED

# Architecture Design: Unified Dependency Resolver
|
||||
|
||||
## 1. System Architecture
|
||||
|
||||
### 1.1 Module Location
|
||||
|
||||
```
|
||||
comfyui_manager/
|
||||
├── glob/
|
||||
│ └── manager_core.py # Existing: execute_install_script() call sites (2 locations)
|
||||
├── common/
|
||||
│ ├── manager_util.py # Existing: get_pip_cmd(), PIPFixer, use_uv flag
|
||||
│ ├── cm_global.py # Existing: pip_overrides, pip_blacklist (runtime dynamic assignment)
|
||||
│ └── unified_dep_resolver.py # New: Unified dependency resolution module
|
||||
├── prestartup_script.py # Existing: config reading, remap_pip_package, cm_global initialization
|
||||
└── legacy/
|
||||
└── manager_core.py # Legacy (not a modification target)
|
||||
```
|
||||
|
||||
The new module `unified_dep_resolver.py` is added to the `comfyui_manager/common/` directory.
|
||||
It reuses `manager_util` utilities and `cm_global` global state from the same package.
|
||||
|
||||
> **Warning**: `cm_global.pip_overrides`, `pip_blacklist`, `pip_downgrade_blacklist` are
|
||||
> NOT defined in `cm_global.py`. They are **dynamically assigned** during `prestartup_script.py` execution.
|
||||
> In v1 unified mode, these are **not applied** — empty values are passed to the resolver constructor.
|
||||
> The constructor interface accepts them for future extensibility (defaults to empty when `None`).
|
||||
>
|
||||
> **[DEFERRED]** Reading actual `cm_global` values at startup is deferred to a future version.
|
||||
> The startup batch resolver in `prestartup_script.py` currently passes `blacklist=set()`,
|
||||
> `overrides={}`, `downgrade_blacklist=[]`. The constructor and internal methods
|
||||
> (`_remap_package`, `_is_downgrade_blacklisted`, blacklist check) are fully implemented
|
||||
> and will work once real values are provided.
|
||||
|
||||

|
||||
end
|
||||
```
|
||||
|
||||
> **Key design change**: The unified resolver runs at **startup time** (module scope), not at install time.
|
||||
> At install time, `execute_install_script()` skips the pip loop when unified mode is active.
|
||||
> At startup, `prestartup_script.py` runs the resolver at module scope — unconditionally when enabled,
|
||||
> independent of `install-scripts.txt` existence. Blacklist/overrides/downgrade_blacklist are bypassed
|
||||
> (empty values passed); `uv pip compile` handles all conflict resolution natively.
|
||||
>
|
||||
> **Note**: `execute_install_script()` exists in 2 locations in the codebase (excluding legacy module).
|
||||
> - `UnifiedManager.execute_install_script()` (class method): Used for CNR installs, etc.
|
||||
> - Standalone function `execute_install_script()`: Used for updates, git installs, etc.
|
||||
> Both skip per-node pip install when unified mode is active.
|
||||
|
||||
### 1.3 uv Command Strategy
|
||||
|
||||
**`uv pip compile`** → Generates pinned requirements.txt (pip-compatible)
|
||||
- Do not confuse with `uv lock`
|
||||
- `uv lock` generates `uv.lock` (TOML) — cross-platform but incompatible with pip workflows
|
||||
- This design uses a pip-compatible workflow (`uv pip compile` → `uv pip install -r`)
|
||||
|
||||
**`uv pip install -r`** ← Used instead of `uv pip sync`
|
||||
- `uv pip sync`: **Deletes** packages not in lockfile → Risk of removing torch, ComfyUI deps
|
||||
- `uv pip install -r`: Only performs additive installs, preserves existing packages → Safe

|
||||
```
|
||||
|
||||
### 3.2 Lockfile Generation (`compile_lockfile`)
|
||||
|
||||
**Behavior:**
|
||||
1. Create a unique temp directory (`tempfile.mkdtemp(prefix="comfyui_resolver_")`) for concurrency safety
|
||||
2. Write collected requirements and base constraints to temp files
|
||||
3. Execute `uv pip compile` with options:
|
||||
- `--output-file` (pinned requirements path within temp dir)
|
||||
- `--python` (current interpreter)
|
||||
- `--constraint` (base dependencies)
|
||||
- `--extra-index-url` (from `CollectedDeps.extra_index_urls`, logged via `_redact_url()`)
|
||||
4. Timeout: 300s — returns `LockfileResult(success=False)` on `TimeoutExpired`
|
||||
5. On `returncode != 0`: parse stderr for conflict details via `_parse_conflicts()`
|
||||
6. Post-success verification: confirm lockfile was actually created (handles edge case of `returncode==0` without output)
|
||||
7. Temp directory cleanup: `shutil.rmtree()` in `except` block; on success, caller (`resolve_and_install`'s `finally`) handles cleanup
|
||||
|
||||
### 3.3 Dependency Installation (`install_from_lockfile`)
|
||||
|
||||
**Behavior:**
|
||||
1. Execute `uv pip install --requirement <lockfile_path> --python <sys.executable>`
|
||||
- **NOT `uv pip sync`** — sync deletes packages not in lockfile (dangerous for torch, ComfyUI deps)
|
||||
2. `uv pip install -r` is **atomic** (all-or-nothing): no partial failure
|
||||
3. Timeout: 600s — returns `InstallResult(success=False)` on `TimeoutExpired`
|
||||
4. On success: parse stdout via `_parse_install_output()` to populate `installed`/`skipped` lists
|
||||
5. On failure: `stderr` captures the failure cause; `installed=[]` (atomic model)
|
||||
|
||||
### 3.4 uv Command Resolution
|
||||
|
||||
**`_get_uv_cmd()` resolution order** (mirrors existing `get_pip_cmd()` pattern):
|
||||
1. **Module uv**: `[sys.executable, '-m', 'uv']` (with `-s` flag for embedded Python — note: `python_embeded` spelling is intentional, matching ComfyUI Windows distribution path)
|
||||
2. **Standalone uv**: `['uv']` via `shutil.which('uv')`
|
||||
3. **Not found**: raises `UvNotAvailableError` → caught by caller for pip fallback
|
||||
|
||||
### 3.5 Stale Temp File Cleanup
|
||||
|
||||
**`cleanup_stale_tmp(max_age_seconds=3600)`** — classmethod, called at start of `resolve_and_install()`:
|
||||
- Scans `tempfile.gettempdir()` for directories with prefix `comfyui_resolver_`
|
||||
- Deletes directories older than `max_age_seconds` (default: 1 hour)
|
||||
- Silently ignores `OSError` (permission issues, etc.)
|
||||
|
||||
### 3.6 Credential Redaction
|
||||
|
||||
```python
|
||||
_CREDENTIAL_PATTERN = re.compile(r'://([^@]+)@')
|
||||
|
||||
def _redact_url(self, url: str) -> str:
|
||||
"""Mask authentication info in URLs. user:pass@host → ****@host"""
|
||||
return self._CREDENTIAL_PATTERN.sub('://****@', url)
|
||||
```
|
||||
|
||||
All `--extra-index-url` logging passes through `_redact_url()`:
|
||||
```python
|
||||
# Logging example within compile_lockfile()
|
||||
for url in deps.extra_index_urls:
|
||||
logging.info(f"[UnifiedDepResolver] extra-index-url: {self._redact_url(url)}")
|
||||
cmd += ["--extra-index-url", url] # Original URL passed to actual command
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. Existing Code Integration
|
||||
|
||||
### 4.1 manager_core.py Modification Points
|
||||
|
||||
**2 `execute_install_script()` locations — both skip deps in unified mode:**
|
||||
|
||||
#### 4.1.1 UnifiedManager.execute_install_script() (Class Method)
|
||||
|
||||
#### 4.1.2 Standalone Function execute_install_script()
|
||||
|
||||
**Both locations use the same pattern when unified mode is active:**
|
||||
|
||||
1. `lazy_mode=True` → schedule and return early (unchanged)
|
||||
2. If `not no_deps and manager_util.use_unified_resolver`:
|
||||
- **Skip** the `requirements.txt` pip install loop entirely (deps deferred to startup)
|
||||
- Log: `"[UnifiedDepResolver] deps deferred to startup batch resolution"`
|
||||
3. If `not manager_util.use_unified_resolver`: existing pip install loop runs (unchanged)
|
||||
4. `install.py` execution: **always runs immediately** regardless of resolver mode
|
||||
|
||||
> **Parameter ordering differs:**
|
||||
> - Method: `(self, url, repo_path, instant_execution, lazy_mode, no_deps)`
|
||||
> - Standalone: `(url, repo_path, lazy_mode, instant_execution, no_deps)`
|
||||
|
||||
### 4.1.3 Startup Batch Resolver (`prestartup_script.py`)
|
||||
|
||||
**New**: Runs unified resolver at **module scope** — unconditionally when enabled, independent of `install-scripts.txt` existence.
|
||||
|
||||
**Execution point**: After config reading and `cm_global` initialization, **before** the `execute_startup_script()` gate.
|
||||
|
||||
**Logic** (uses module-level helpers from `unified_dep_resolver.py`):
|
||||
1. `collect_node_pack_paths(folder_paths.get_folder_paths('custom_nodes'))` — enumerate all installed node pack directories
|
||||
2. `collect_base_requirements(comfy_path)` — read `requirements.txt` + `manager_requirements.txt` from ComfyUI root (base deps only)
|
||||
3. Create `UnifiedDepResolver` with **empty** blacklist/overrides/downgrade_blacklist (uv handles resolution natively; interface preserved for extensibility)
|
||||
4. Call `resolve_and_install()` → on success set `_unified_resolver_succeeded = True`
|
||||
5. On failure (including `UvNotAvailableError`): log warning, fall back to per-node pip
|
||||
|
||||
> `manager_requirements.txt` is read **only** from `comfy_path` (ComfyUI base), never from node packs.
|
||||
> Node packs' `requirements.txt` are collected by the resolver's `collect_requirements()` method.
|
||||
|
||||
### 4.1.5 `execute_lazy_install_script()` Modification
|
||||
|
||||
When unified resolver **succeeds**, `execute_lazy_install_script()` skips the per-node pip install loop
|
||||
(deps already batch-resolved at module scope). `install.py` still runs per node pack.
|
||||
|
||||
```python
|
||||
# In execute_lazy_install_script():
|
||||
if os.path.exists(requirements_path) and not _unified_resolver_succeeded:
|
||||
# Per-node pip install: only runs if unified resolver is disabled or failed
|
||||
...
|
||||
# install.py always runs regardless
|
||||
```
|
||||
|
||||
> **Note**: Gated on `_unified_resolver_succeeded` (success flag), NOT `use_unified_resolver` (enable flag).
|
||||
> If the resolver is enabled but fails, `_unified_resolver_succeeded` remains False → per-node pip runs as fallback.
|
||||
|
||||
### 4.2 Configuration Addition (config.ini)
|
||||
|
||||
```ini
|
||||
[default]
|
||||
# Existing settings...
|
||||
use_unified_resolver = false # Enable unified dependency resolution
|
||||
```
|
||||
|
||||
### 4.3 Configuration Reading
|
||||
|
||||
Follows the existing `read_uv_mode()` / `use_uv` pattern:
|
||||
- `prestartup_script.py`: `read_unified_resolver_mode()` reads from `default_conf` → sets `manager_util.use_unified_resolver`
|
||||
- `manager_core.py`: `read_config()` / `write_config()` / `get_config()` include `use_unified_resolver` key
|
||||
- `read_config()` exception fallback must include `use_unified_resolver` key to prevent `KeyError` in `write_config()`
|
||||
|
||||
### 4.4 manager_util.py Extension
|
||||
|
||||
```python
|
||||
# manager_util.py
|
||||
use_unified_resolver = False # New global flag (separate from use_uv)
|
||||
```

## 9. Test Strategy
|
||||
|
||||
### 9.1 Unit Tests
|
||||
|
||||
| Test Target | Cases |
|
||||
|------------|-------|
|
||||
| `collect_requirements` | Normal parsing, empty file, blacklist filtering, comment handling, remap application |
|
||||
| `.disabled` filtering | Exclude node packs within `.disabled/` directory path (directory-based mechanism) |
|
||||
| Input sanitization | Reject lines with `-r`, `-e`, `--find-links`, `@ file://`, path separators |
|
||||
| `--index-url` / `--extra-index-url` separation | `package --index-url URL`, standalone `--index-url URL`, standalone `--extra-index-url URL`, `package --extra-index-url URL` → package spec + extra_index_urls separation |
|
||||
| Downgrade blacklist | Installed + lower version request → skip, not installed → pass, same/higher version → pass |
|
||||
| `compile_lockfile` | Normal compilation, conflict detection, TimeoutExpired, constraint application, --output-file verification |
|
||||
| Lockfile existence verification | Failure handling when file not created despite returncode==0 |
|
||||
| `extra_index_urls` passthrough | Verify `--extra-index-url` argument included in compile command |
|
||||
| `install_from_lockfile` | Normal install, total failure, TimeoutExpired |
|
||||
| Atomic model | On failure: installed=[], stderr populated |
|
||||
| `_get_uv_cmd` | Module uv, standalone uv, embedded python (`python_embeded`), not installed |
|
||||
| `_remap_package` | pip_overrides remapping, unregistered packages |
|
||||
| Blacklist | torch family, torchsde, custom blacklist |
|
||||
| Duplicate handling | Same package with multiple specs → all passed to uv |
|
||||
| Multiple paths | Collection from multiple custom_nodes paths |
|
||||
| `cm_global` defense | Default values used when `pip_blacklist` etc. not assigned |
|
||||
| Concurrency | Two resolver instances each use unique temp directories |
|
||||
| Credential redaction | `user:pass@host` URL masked in log output |
|
||||
| `_redact_url` | `://user:pass@host` → `://****@host` conversion, no-credential URL passthrough |
|
||||
| `cleanup_stale_tmp` | Delete stale dirs >1 hour, preserve recent dirs, ignore permission errors |
|
||||
| Downgrade operators | `<=`, `==`, `<`, `~=` blocked; `>=`, `>`, `!=` pass; no spec + installed → blocked |
|
||||
| `StrictVersion` comparison | Verify `manager_util.StrictVersion` is used (not `packaging.version`) |
|
||||
|
||||
### 9.2 Integration Tests
|
||||
|
||||
- End-to-end test in real uv environment
|
||||
- Existing pip fallback path test
|
||||
- config.ini setting toggle test
|
||||
- Environment integrity verification after PIPFixer call
|
||||
- lazy_mode scheduling behavior verification (Windows simulation)
|
||||
- `use_uv=False` + `use_unified_resolver=True` combination test
|
||||
- Large-scale dependency (50+ node packs) performance test
|
||||
|
||||
---
|
||||
|
||||
## 10. Implementation Order
|
||||
|
||||
1. **Phase 1**: Data classes and `collect_requirements` implementation + tests
|
||||
- PackageRequirement, CollectedDeps (including extra_index_urls) and other data classes
|
||||
- Blacklist/override filtering
|
||||
- **Downgrade blacklist** (version comparison logic included)
|
||||
- **Input sanitization** (-r, -e, @ file:// etc. rejection)
|
||||
- **`--index-url` / `--extra-index-url` separation handling** (package spec + extra_index_urls)
|
||||
- **`.disabled` node pack filtering**
|
||||
- Defensive cm_global access (getattr pattern)
|
||||
2. **Phase 2**: `compile_lockfile` implementation + tests
|
||||
- uv pip compile invocation
|
||||
- --output-file, --constraint, --python options
|
||||
- Conflict parsing logic
|
||||
3. **Phase 3**: `install_from_lockfile` implementation + tests
|
||||
- uv pip install -r invocation (NOT sync)
|
||||
- Install result parsing
|
||||
4. **Phase 4**: Integration — startup batch + install-time skip
|
||||
- `prestartup_script.py`: Module-scope startup batch resolver + `execute_lazy_install_script()` deps skip
|
||||
- `manager_core.py`: Skip per-node pip in 2 `execute_install_script()` locations
|
||||
- `manager_util.py`: `use_unified_resolver` flag
|
||||
- Config reading (`read_unified_resolver_mode()`, `read_config()`/`write_config()`)
|
||||
5. **Phase 5**: Integration tests + fallback verification + startup batch tests
|
||||

## Appendix A: Existing Code Reference
|
||||
|
||||
> **Note**: Line numbers may shift as code changes, so references use symbol names (function/class names).
|
||||
> Use `grep -n` or IDE symbol search for exact locations.
|
||||
|
||||
### remap_pip_package Location (Code Duplication Exists)
|
||||
|
||||
```
|
||||
comfyui_manager/glob/manager_core.py — def remap_pip_package(pkg)
|
||||
comfyui_manager/prestartup_script.py — def remap_pip_package(pkg)
|
||||
```
|
||||
|
||||
Both reference `cm_global.pip_overrides` with identical logic.
|
||||
The unified resolver uses `cm_global.pip_overrides` directly to avoid adding more duplication.
|
||||
|
||||
### cm_global Global State
|
||||
|
||||
```python
|
||||
# Dynamically assigned in prestartup_script.py (NOT defined in cm_global.py!)
|
||||
cm_global.pip_blacklist = {'torch', 'torchaudio', 'torchsde', 'torchvision'} # set
|
||||
cm_global.pip_overrides = {} # dict, loaded from JSON
|
||||
cm_global.pip_downgrade_blacklist = [ # list
|
||||
'torch', 'torchaudio', 'torchsde', 'torchvision',
|
||||
'transformers', 'safetensors', 'kornia'
|
||||
]
|
||||
```
|
||||
|
||||
> **cm_cli path**: `cm_cli/__main__.py` also independently initializes these attributes.
|
||||
> If the resolver may be called from the CLI path, this initialization should also be verified.
|
||||
|
||||
### PIPFixer Call Pattern
|
||||
|
||||
```python
|
||||
# Within UnifiedManager.execute_install_script() method in manager_core.py:
|
||||
pip_fixer = manager_util.PIPFixer(
|
||||
manager_util.get_installed_packages(),
|
||||
context.comfy_path,
|
||||
context.manager_files_path
|
||||
)
|
||||
# ... (after installation)
|
||||
pip_fixer.fix_broken()
|
||||
```
|
||||
|
||||
The unified resolver does not call PIPFixer directly.
|
||||
The caller (execute_install_script) calls PIPFixer as part of the existing flow.
|
||||
|
||||
### is_blacklisted() Logic (Must Be Reproduced in Unified Resolver)
|
||||
|
||||
```python
|
||||
# manager_core.py — def is_blacklisted(name)
|
||||
# 1. Simple pip_blacklist membership check
|
||||
# 2. pip_downgrade_blacklist version comparison:
|
||||
# - Parse spec with regex r'([^<>!~=]+)([<>!~=]=?)([^ ]*)'
|
||||
# - match is None (no version spec) + installed → block
|
||||
# - Operator in ['<=', '==', '<', '~='] + installed version >= requested version → block
|
||||
# - Version comparison uses manager_util.StrictVersion (NOT packaging.version)
|
||||
```
|
||||
|
||||
The unified resolver's `_is_downgrade_blacklisted()` method faithfully reproduces this logic.
|
||||
It uses `manager_util.StrictVersion` instead of `packaging.version.parse()` to ensure consistency with existing behavior.
|
||||
|
||||
### Existing Code --index-url Handling (Asymmetric)
|
||||
|
||||
```python
|
||||
# Only exists in standalone function execute_install_script():
|
||||
if '--index-url' in package_name:
|
||||
s = package_name.split('--index-url')
|
||||
install_cmd = manager_util.make_pip_cmd(["install", s[0].strip(), '--index-url', s[1].strip()])
|
||||
|
||||
# UnifiedManager.execute_install_script() method does NOT have this handling
|
||||
```
|
||||
|
||||
The unified resolver unifies both paths for consistent handling via `_split_index_url()`.

# PRD: Unified Dependency Resolver
|
||||
|
||||
## 1. Overview
|
||||
|
||||
### 1.1 Background
|
||||
ComfyUI Manager currently installs each node pack's `requirements.txt` individually via `pip install`.
|
||||
This approach causes dependency conflicts where installing a new node pack can break previously installed node packs' dependencies.
|
||||
|
||||
**Current flow:**
|
||||
```mermaid
|
||||
graph LR
|
||||
A1[Install node pack A] --> A2[pip install A's deps] --> A3[Run install.py]
|
||||
B1[Install node pack B] --> B2[pip install B's deps] --> B3[Run install.py]
|
||||
B2 -.->|May break<br/>A's deps| A2
|
||||
```
|
||||
|
||||
### 1.2 Goal
|
||||
Implement a unified dependency installation module that uses `uv` to resolve all dependencies (installed node packs + new node packs) at once.
|
||||
|
||||
**New flow (unified resolver mode):**
|
||||
```mermaid
|
||||
graph TD
|
||||
subgraph "Install Time (immediate)"
|
||||
A1[User installs node pack X] --> A2[Git clone / download]
|
||||
A2 --> A3["Run X's install.py (if exists)"]
|
||||
A3 --> A4["Skip per-node pip install<br/>(deps deferred to restart)"]
|
||||
end
|
||||
|
||||
subgraph "ComfyUI Restart (startup batch)"
|
||||
B1[prestartup_script.py] --> B2[Collect ALL installed node packs' deps]
|
||||
B2 --> B3["uv pip compile → pinned requirements.txt"]
|
||||
B3 --> B4["uv pip install -r → Batch install"]
|
||||
B4 --> B5[PIPFixer environment correction]
|
||||
end
|
||||
```
|
||||
|
||||
> **Terminology**: In this document, "lockfile" refers to the **pinned requirements.txt** generated by `uv pip compile`.
|
||||
> This is different from the `uv.lock` (TOML format) generated by `uv lock`. We use a pip-compatible workflow.
|
||||
|
||||
### 1.3 Scope
|
||||
- Develop a new dedicated dependency resolution module
|
||||
- Opt-in activation from the existing install process
|
||||
- **Handles dependency resolution (deps install) only**. `install.py` execution is handled by existing logic
|
||||
|
||||
---
|
||||
|
||||
## 2. Constraints
|
||||
|
||||
| Item | Description |
|
||||
|------|-------------|
|
||||
| **uv required** | Only operates in environments where `uv` is available |
|
||||
| **Independent of `use_uv` flag** | `use_unified_resolver` is separate from the existing `use_uv` flag. Even if `use_uv=False`, setting `use_unified_resolver=True` attempts resolver activation. Auto-fallback if uv is not installed |
|
||||
| **Pre-validated list** | Input node pack list is assumed to be pre-verified for mutual dependency compatibility |
|
||||
| **Backward compatibility** | Existing pip-based install process is fully preserved (fallback) |
|
||||
| **Blacklist/overrides bypassed** | In unified mode, `pip_blacklist`, `pip_overrides`, `pip_downgrade_blacklist` are NOT applied (empty values passed). Constructor interface is preserved for future extensibility. `uv pip compile` handles all conflict resolution natively. **[DEFERRED]** Reading actual values from `cm_global` at startup is deferred to a future version — v1 always passes empty values |
|
||||
| **Multiple custom_nodes paths** | Supports all paths returned by `folder_paths.get_folder_paths('custom_nodes')` |
|
||||
| **Scope of application** | Batch resolver runs at **module scope** in `prestartup_script.py` (unconditionally when enabled, independent of `install-scripts.txt` existence). The 2 `execute_install_script()` locations skip per-node pip install when unified mode is active (deps deferred to restart). `execute_lazy_install_script()` is also modified to skip per-node pip install in unified mode. Other install paths such as `install_manager_requirements()`, `pip_install()` are outside v1 scope (future extension) |
|
||||
| **Legacy module** | `comfyui_manager/legacy/manager_core.py` is excluded from modification. Legacy paths retain existing pip behavior |
|
||||
|
||||
---
|
||||
|
||||
## 3. Functional Requirements
|
||||
|
||||
### FR-1: Node Pack List and Base Dependency Input
|
||||
|
||||
**Input:**
|
||||
- Node pack list (fullpath list of installed + to-be-installed node packs)
|
||||
- Base dependencies (ComfyUI's `requirements.txt` and `manager_requirements.txt`)
|
||||
|
||||
**Behavior:**
|
||||
- Validate each node pack path
|
||||
- Exclude disabled (`.disabled`) node packs
|
||||
- Detection criteria: Existence of `custom_nodes/.disabled/{node_pack_name}` **directory**
|
||||
- Existing mechanism: Disabling a node pack **moves** it from `custom_nodes/` to `custom_nodes/.disabled/` (does NOT create a `.disabled` file inside the node pack)
|
||||
- At resolver input time, disabled node packs should already be absent from `custom_nodes/`, so normally they won't be in `node_pack_paths`
|
||||
- Defensively exclude any node pack paths that are within the `.disabled` directory
|
||||
- Base dependencies are treated as constraints
|
||||
- Traverse all paths from `folder_paths.get_folder_paths('custom_nodes')`
|
||||
|
||||
**`cm_global` runtime dependencies:**
|
||||
- `cm_global.pip_overrides`, `pip_blacklist`, `pip_downgrade_blacklist` are dynamically assigned during `prestartup_script.py` execution
|
||||
- In unified mode, these are **not applied** — empty values are passed to the resolver constructor
|
||||
- The constructor interface accepts these parameters for future extensibility (defaults to empty when `None`)
|
||||
|
||||
### FR-2: Dependency List Extraction
|
||||
|
||||
**Behavior:**
|
||||
- Parse `requirements.txt` from each node pack directory
|
||||
- Encoding: Use `robust_readlines()` pattern (`chardet` detection, assumes UTF-8 if not installed)
|
||||
- Package name remapping (constructor accepts `overrides` dict — **empty in v1**, interface preserved for extensibility)
|
||||
- Blacklist package filtering (constructor accepts `blacklist` set — **empty in v1**, uv handles torch etc. natively)
|
||||
- Downgrade blacklist filtering (constructor accepts `downgrade_blacklist` list — **empty in v1**)
|
||||
- **Note**: In unified mode, `uv pip compile` resolves all version conflicts natively. The blacklist/overrides/downgrade_blacklist mechanisms from the existing pip flow are bypassed
|
||||
- Strip comments (`#`) and blank lines
|
||||
- **Input sanitization** (see below)
|
||||
- Separate handling of `--index-url` entries (see below)
|
||||
|
||||
**Input sanitization:**
|
||||
- Requirements lines matching the following patterns are **rejected and logged** (security defense):
|
||||
- `-r`, `--requirement` (recursive include → path traversal risk)
|
||||
- `-e`, `--editable` (VCS/local path install → arbitrary code execution risk)
|
||||
- `-c`, `--constraint` (external constraint file injection)
|
||||
- `--find-links`, `-f` (external package source specification)
|
||||
- `@ file://` (local file reference → path traversal risk)
|
||||
- Package names containing path separators (`/`, `\`)
|
||||
- Allowed items: Package specs (`name>=version`), specs with `--index-url`, environment markers (containing `;`)
|
||||
- Rejected lines are recorded in the `skipped` list with reason
|
||||
|
||||
**`--index-url` handling:**
|
||||
- Existing code (standalone function `execute_install_script()`) parses `package_name --index-url URL` format for special handling
|
||||
- **Note**: The class method `UnifiedManager.execute_install_script()` does NOT have this handling (asymmetric)
|
||||
- The unified resolver **unifies both paths** for consistent handling:
|
||||
- Package spec → added to the general dependency list
|
||||
- `--extra-index-url URL` → passed as `uv pip compile` argument
|
||||
- Separated index URLs are collected in `CollectedDeps.extra_index_urls`
|
||||
- **Credential redaction**: Authentication info (`user:pass@`) in index URLs is masked during logging
|
||||
|
||||
**Duplicate handling strategy:**
|
||||
- No deduplication is performed directly
|
||||
- Different version specs of the same package are **all passed as-is** to uv
|
||||
- `uv pip compile` handles version resolution (uv determines the optimal version)
|
||||
|
||||
**Output:**
|
||||
- Unified dependency list (tracked by source node pack)
|
||||
- Additional index URL list
|
||||
|
||||
### FR-3: uv pip compile Execution
|
||||
|
||||
**Behavior:**
|
||||
- Generate temporary requirements file from the collected dependency list
|
||||
- Execute `uv pip compile` to produce a pinned requirements.txt
|
||||
- `--output-file` (required): Specify output file (outputs to stdout only if not specified)
|
||||
- `--constraint`: Pass base dependencies as constraints
|
||||
- `--python`: Current Python interpreter path
|
||||
- `--extra-index-url`: Additional index URLs collected from FR-2 (multiple allowed)
|
||||
- Resolve for the current platform (platform-specific results)
|
||||
|
||||
**Error handling:**
|
||||
- Return conflict package report when resolution fails
|
||||
- Timeout handling (300s): Explicitly catch `subprocess.TimeoutExpired`, terminate child process, then fallback
|
||||
- Lockfile output file existence verification: Confirm file was actually created even when `returncode == 0`
|
||||
- Temp file cleanup: Guaranteed in `finally` block. Includes stale temp file cleanup logic at next execution for abnormal termination (SIGKILL) scenarios
|
||||
|
||||
**Output:**
|
||||
- pinned requirements.txt (file with all packages pinned to exact versions)
|
||||
|
||||
### FR-4: Pinned Requirements-based Dependency Installation
|
||||
|
||||
**Behavior:**
|
||||
- Execute `uv pip install -r <pinned-requirements.txt>`
|
||||
- **Do NOT use `uv pip sync`**: sync deletes packages not in the lockfile, risking removal of torch, ComfyUI's own dependencies, etc.
|
||||
- Already-installed packages at the same version are skipped (default uv behavior)
|
||||
- Log installation results
|
||||
|
||||
**Error handling:**
|
||||
- `uv pip install -r` is an **atomic operation** (all-or-nothing)
|
||||
- On total failure: Parse stderr for failure cause report → fallback to existing pip
|
||||
- **No partial failure report** (not possible due to uv's behavior)
|
||||
- `InstallResult`'s `installed`/`skipped` fields are populated by parsing uv stdout; `stderr` records failure cause (no separate `failed` field needed due to atomic model)
|
||||
|
||||
### FR-5: Post-install Environment Correction
|
||||
|
||||
**Behavior:**
|
||||
- Call `PIPFixer.fix_broken()` for environment integrity correction
|
||||
- Restore torch version (when change detected)
|
||||
- Fix OpenCV conflicts
|
||||
- Restore comfyui-frontend-package
|
||||
- Restore packages based on `pip_auto_fix.list`
|
||||
- **This step is already performed in the existing `execute_install_script()` flow, so the unified resolver itself doesn't need to call it**
|
||||
- However, an optional call option is provided for cases where the resolver is invoked independently outside the existing flow
|
||||
|
||||
### FR-6: install.py Execution (Existing Flow Maintained)
|
||||
|
||||
**Behavior:**
|
||||
- The unified resolver handles deps installation **at startup time only**
|
||||
- `install.py` execution is handled by the existing `execute_install_script()` flow and runs **immediately** at install time
|
||||
- Deps are deferred to startup batch resolution; `install.py` runs without waiting for deps
|
||||
|
||||
**Control flow specification (unified mode active):**
|
||||
- `execute_install_script()`: **skip** the `requirements.txt`-based individual pip install loop entirely (deps will be resolved at next restart)
|
||||
- `install.py` execution runs **immediately** as before
|
||||
- At next ComfyUI restart: `prestartup_script.py` runs the unified resolver for all installed node packs
|
||||
|
||||
**Control flow specification (unified mode inactive / fallback):**
|
||||
- Existing pip install loop runs as-is (no change)
|
||||
- `install.py` execution runs **immediately** as before
|
||||
|
||||
### FR-7: Startup Batch Resolution
|
||||
|
||||
**Behavior:**
|
||||
- When `use_unified_resolver=True`, **all dependency resolution is deferred to ComfyUI startup**
|
||||
- At install time: node pack itself is installed (git clone, etc.) and `install.py` runs immediately, but `requirements.txt` deps are **not** installed per-request
|
||||
- At startup time: `prestartup_script.py` runs the unified resolver once for all installed node packs
|
||||
|
||||
**Startup execution flow (in `prestartup_script.py`):**
|
||||
1. At **module scope** (before `execute_startup_script()` gate): check `manager_util.use_unified_resolver` flag
|
||||
2. If enabled: collect all installed node pack paths, read base requirements from `comfy_path`
|
||||
3. Create `UnifiedDepResolver` with empty blacklist/overrides/downgrade_blacklist (uv handles resolution natively)
|
||||
4. Call `resolve_and_install()` — collects all deps → compile → install in one batch
|
||||
5. On success: set `_unified_resolver_succeeded = True`, skip per-node pip in `execute_lazy_install_script()`
|
||||
6. On failure: log warning, `execute_lazy_install_script()` falls back to existing per-node pip install
|
||||
7. **Note**: Runs unconditionally when enabled, independent of `install-scripts.txt` existence
|
||||
|
||||
**`execute_install_script()` behavior in unified mode:**
|
||||
- Skip the `requirements.txt` pip install loop entirely (deps will be handled at restart)
|
||||
- `install.py` execution still runs immediately
|
||||
|
||||
**`execute_lazy_install_script()` behavior in unified mode:**
|
||||
- Skip the `requirements.txt` pip install loop (already handled by startup batch resolver)
|
||||
- `install.py` execution still runs
|
||||
|
||||
**Windows-specific behavior:**
|
||||
- Windows lazy install path also benefits from startup batch resolution
|
||||
- `try_install_script()` defers to `reserve_script()` as before for non-`instant_execution=True` installs

## 4. Non-functional Requirements
|
||||
|
||||
| Item | Requirement |
|
||||
|------|-------------|
|
||||
| **Performance** | Equal to or faster than existing individual installs |
|
||||
| **Stability** | Must not break the existing environment |
|
||||
| **Logging** | Log progress and results at each step (details below) |
|
||||
| **Error recovery** | Fallback to existing pip method on failure |
|
||||
| **Testing** | Unit test coverage above 80% |
|
||||
| **Security** | requirements.txt input sanitization (see FR-2), credential log redaction, subprocess list-form invocation |
|
||||
| **Concurrency** | Prevent lockfile path collisions on concurrent install requests. Use process/thread-unique suffixes or temp directories |
|
||||
| **Temp files** | Guarantee temp file cleanup on both normal and abnormal termination. Clean stale files on next execution |
|
||||
|
||||
### Logging Requirements
|
||||
|
||||
| Step | Log Level | Content |
|
||||
|------|-----------|---------|
|
||||
| Resolver start | `INFO` | Node pack count, total dependency count, mode (unified/pip) |
|
||||
| Dependency collection | `INFO` | Collection summary (collected N, skipped N, sources N) |
|
||||
| Dependency collection | `DEBUG` | Per-package collection/skip/remap details |
|
||||
| `--index-url` detection | `INFO` | Detected additional index URL list |
|
||||
| uv compile start | `INFO` | Execution command (excluding sensitive info) |
|
||||
| uv compile success | `INFO` | Pinned package count, elapsed time |
|
||||
| uv compile failure | `WARNING` | Conflict details, fallback transition notice |
|
||||
| Install start | `INFO` | Number of packages to install |
|
||||
| Install success | `INFO` | Installed/skipped/failed count summary, elapsed time |
|
||||
| Install failure | `WARNING` | Failed package list, fallback transition notice |
|
||||
| Fallback transition | `WARNING` | Transition reason, original error message |
|
||||
| Overall completion | `INFO` | Final result summary (success/fallback/failure) |
|
||||
|
||||
> **Log prefix**: All logs use `[UnifiedDepResolver]` prefix to distinguish from existing pip install logs
|
||||

||||
## 5. Usage Scenarios
|
||||
|
||||
### Scenario 1: Single Node Pack Installation (unified mode)
|
||||
```
|
||||
User requests installation of node pack X
|
||||
→ Git clone / download node pack X
|
||||
→ Run X's install.py (if exists) — immediately
|
||||
→ Skip per-node pip install (deps deferred)
|
||||
→ User restarts ComfyUI
|
||||
→ prestartup_script.py: Collect deps from ALL installed node packs (A,B,C,X)
|
||||
→ uv pip compile resolves fully compatible versions
|
||||
→ uv pip install -r for batch installation
|
||||
→ PIPFixer environment correction
|
||||
```
|
||||
|
||||
### Scenario 2: Multi Node Pack Batch Installation (unified mode)
|
||||
```
|
||||
User requests installation of node packs X, Y, Z
|
||||
→ Each node pack: git clone + install.py — immediately
|
||||
→ Per-node pip install skipped for all
|
||||
→ User restarts ComfyUI
|
||||
→ prestartup_script.py: Collect deps from ALL installed node packs (including X,Y,Z)
|
||||
→ Single uv pip compile → single uv pip install -r
|
||||
→ PIPFixer environment correction
|
||||
```
|
||||
|
||||
### Scenario 3: Dependency Resolution Failure (Edge Case)
|
||||
```
|
||||
Even pre-validated lists may fail due to uv version differences or platform issues
|
||||
→ uv pip compile failure → return conflict report
|
||||
→ Display conflict details to user
|
||||
→ Auto-execute existing pip fallback
|
||||
```
|
||||
|
||||
### Scenario 4: uv Not Installed
|
||||
```
|
||||
uv unavailable detected → auto-fallback to existing pip method
|
||||
→ Display uv installation recommendation to user
|
||||
```
|
||||
|
||||
### Scenario 5: Windows Lazy Installation (unified mode)
|
||||
```
|
||||
Node pack installation requested on Windows
|
||||
→ Node pack install deferred to startup (existing lazy mechanism)
|
||||
→ On next ComfyUI startup: unified resolver runs first (batch deps)
|
||||
→ execute_lazy_install_script() skips per-node pip (already resolved)
|
||||
→ install.py still runs per node pack
|
||||
```
|
||||
|
||||
### Scenario 6: Malicious/Non-standard requirements.txt
|
||||
```
|
||||
Node pack's requirements.txt contains `-r ../../../etc/hosts` or `-e git+https://...`
|
||||
→ Sanitization filter rejects the line
|
||||
→ Log rejection reason and continue processing remaining valid packages
|
||||
→ Notify user of rejected item count
|
||||
```
|
||||
|
||||
### Scenario 7: Concurrent Install Requests (unified mode)
|
||||
```
|
||||
User requests installation of node packs A and B nearly simultaneously from UI
|
||||
→ Each request: git clone + install.py immediately, deps skipped
|
||||
→ On restart: single unified resolver run handles both A and B deps together
|
||||
→ No concurrency issue (single batch at startup)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 6. Success Metrics
|
||||
|
||||
| Metric | Target |
|
||||
|--------|--------|
|
||||
| Dependency conflict reduction | 90%+ reduction compared to current |
|
||||
| Install success rate | 99%+ (for compatibility-verified lists) |
|
||||
| Performance | Equal to or better than existing individual installs |
|
||||
| Adoption rate | 50%+ of eligible users |
|
||||
|
||||

|
||||
|
||||
## 7. Future Extensions
|
||||
|
||||
- **`cm_global` integration** [DEFERRED]: Read `pip_blacklist`, `pip_overrides`, `pip_downgrade_blacklist` from `cm_global` runtime values instead of passing empty. Constructor interface already accepts these parameters
|
||||
- Lockfile caching: Reuse for identical node pack configurations
|
||||
- Pre-install dependency conflict validation API: Check compatibility before installation
|
||||
- Dependency tree visualization: Display dependency relationships to users
|
||||
- `uv lock`-based cross-platform lockfile support (TOML format)
|
||||
- `install_manager_requirements()` integration: Resolve manager's own dependencies through unified resolver
|
||||
- `pip_install()` integration: Route UI direct installs through unified resolver
|
||||
- Legacy module (`comfyui_manager/legacy/`) unified resolver support
