perf(workspace): resolve the workspace on first read (BE-10535)

[annehe9]

Linear: BE-10535. Follow-up to BE-9907.

Problem

entry() in comfy_cli/cmdline.py:301 calls setup_workspace_manager for every subcommand before dispatch. That eagerly ran get_workspace_path(), which calls check_comfy_repo(os.getcwd()), which imports GitPython and opens the repo. Only --version and --help-json short-circuit before it. Every command that never reads the workspace (knowledge, cloud, skills, ...) paid for a value it discards.

Change

Option 2 from the ticket. setup_workspace_manager now only stores the flags. workspace_path and workspace_type are properties that resolve on first read and cache the pair.

Confirmed nothing reads the path eagerly, so no fallback to option 1 was needed. Every reader is inside a command handler: cmdline.py:749/816/1687/1697, command/build.py:933+, command/launch.py:415/432/848, command/custom_nodes/*, command/models/models.py:55. _maybe_nudge_setup and tracking.prompt_tracking_consent do not touch it. command/install.py:273 calls setup_workspace_manager a second time after creating the repo; that discards the cached pair.

The property setters and deleters exist because roughly 100 test call sites do patch.object(manager, "workspace_path", ...). Patching a property needs a setter, and unpatching goes through the deleter.

Measurements

Median of runs on a quiet machine, dependencies from uv sync --locked, two alternating rounds against origin/main.

	main	branch
comfy --json (bare), min of 20	0.13 s / 0.17 s	0.09 s / 0.09 s
git in -X importtime	58 ms	absent

comfy --json knowledge status shows no measurable change (0.86-0.94 s either way). The two sequential authed GETs dominate that command; BE-10534 is the ticket for those.

Tests

uv run --locked --extra dev pytest, matching the CI workflow:

• origin/main: 7281 passed, 39 skipped
• this branch: 7289 passed, 39 skipped

The 8 new tests are in tests/comfy_cli/test_workspace_manager.py. Five of them fail against origin/main, so they pin the change rather than restating it:

• setup_workspace_manager does not probe (check_comfy_repo patched to raise)
• first read resolves exactly once, and caches
• a second setup_workspace_manager discards the cached path
• knowledge status and cloud status run with check_comfy_repo patched to raise
• a subprocess asserts GitPython never reaches sys.modules
• which still resolves the workspace, and the path is None before setup

uvx ruff@0.15.15 check and format --diff both clean, matching .github/workflows/ruff_check.yml.

Behaviour note

get_workspace_path can raise typer.Exit(1) when --recent is passed with no recent workspace set. That now fires on first read rather than in the callback, so comfy --recent knowledge status succeeds instead of aborting. That is the point of the change: a workspace-free command should not be gated on workspace resolution. Every workspace-consuming command still aborts exactly as before.

📝 Walkthrough

Walkthrough

WorkspaceManager now defers workspace detection until a workspace property is read. It caches and invalidates resolution state. Workspace-free commands avoid repository probing and GitPython imports, while which retains workspace resolution.

Changes

Workspace resolution

Layer / File(s)	Summary
Lazy workspace state resolution comfy_cli/workspace_manager.py, tests/comfy_cli/test_workspace_manager.py	Workspace setup now records flags and clears cached state without resolving immediately. The workspace_path and workspace_type properties resolve once, support setters and deleters, and return None before setup. Tests cover caching and re-resolution.
Workspace-free command validation tests/comfy_cli/test_workspace_manager.py	Tests confirm that knowledge status and cloud status skip repository probing and GitPython imports. The which command still resolves and reports the workspace.

Merge Risk: 🔵 Low · up to 48d7f

The PR defers workspace resolution until a command needs it, reducing unnecessary startup work while preserving workspace-consuming behavior. It is mergeable with explicit follow-up to make two CLI tests assert successful execution before checking the targeted conditions; no merge-blocking production risk is identified.

Assert command success before checking the narrow condition.

Approving. Checked the two ways this could bite and both are clean:

• typer.Exit moving from the callback into first-read sites: swept every workspace_manager.workspace_path reader on main for enclosing try/except. The only broad except Exception around a first-read site is the shell-completion helper in custom_nodes/command.py (~499), where returning [] on any failure is exactly right; get_installed_packages catches only subprocess.CalledProcessError, so an Exit still propagates. The disclosed behaviour change (--recent with no recent workspace now succeeds for workspace-free commands, still aborts for consumers) is the point of the ticket.
• The property/patch compatibility story: setter/deleter keep patch.object working, the second-setup discard covers comfy install's re-setup, and the subprocess test pinning GitPython out of sys.modules is the strongest possible guard against regression.

Ran workspace_manager + login + knowledge suites on the branch: 166 passed; CI fully green. Nice measurement discipline in the description.
