feat: symlink Python venvs in worktrees for instant setup#1832
Conversation
Switch venv strategy from RECREATE to SYMLINK so worktree creation is near-instant (matching node_modules behavior). A health check after symlinking verifies the venv is usable; if it fails, falls back to recreate with improved robustness: - Marker-based completion tracking (.setup_complete) detects incomplete venvs - Popen-based subprocess management with proper terminate/kill on timeout - Increased pip install timeout from 120s to 300s Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary of ChangesHello @AndyMik90, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly improves the efficiency and reliability of Python virtual environment management within worktrees. By switching the default strategy for venvs from recreation to symlinking, worktree creation becomes much faster. To ensure robustness, a health check is now performed on symlinked venvs, with an automatic fallback to a more resilient recreate strategy if issues are detected. The recreate process itself has also been made more robust by tracking completion with a marker file, improving process termination on timeouts, and extending pip installation time limits. Highlights

Unused local variable Note test

AI 2 days ago
In general, to fix an unused local variable you either (1) remove the variable and, if needed, keep only the right-hand side expression for its side effects, or (2) rename the variable to a conventionally "unused" name (e.g. _ or unused_results) if you intentionally keep it as documentation or for interface stability.
Here, the test test_venv_symlinked_when_source_exists does not use results at all. The behavior under test is that setup_worktree_dependencies creates a .venv symlink in the worktree. We should therefore keep the call (for its side effects) but drop the unused assignment. The minimal, behavior-preserving change is to replace results = setup_worktree_dependencies(...) with just setup_worktree_dependencies(...) on line 609 in tests/test_worktree_dependencies.py. No new imports or helper methods are needed.

Code Review
This pull request introduces a significant performance improvement for Python worktree setup by switching to symlinking virtual environments instead of recreating them. The implementation is robust, including a health check for the symlinked venv and a fallback to an improved recreation strategy. The recreation strategy itself is also enhanced with completion markers and more reliable process handling. The changes are consistently applied across both the Python backend and the TypeScript frontend, and the new logic is well-covered by tests. I've added a few suggestions for minor improvements in error handling and code duplication. Overall, this is a great enhancement.

To make the cleanup process more robust against the unlikely event that proc.wait() times out after proc.kill(), you can wrap it in a try...except block. This ensures the original TimeoutExpired exception is always the one that propagates from this handler, preventing an unhandled exception from within an exception handler.
debug_warning(MODULE, f"{label} did not terminate, killing process")
proc.kill()
try:
proc.wait(timeout=5)

There was a problem hiding this comment.
The logic to clean up a partially created virtual environment is repeated multiple times in this function (here and in the pip install error handling paths). To improve maintainability and reduce code duplication, consider extracting this cleanup logic into a dedicated helper function, for example:
def _cleanup_failed_venv(venv_path: Path):
"""Safely removes a venv directory if it exists."""
if venv_path.exists():
shutil.rmtree(venv_path, ignore_errors=True)You could then call _cleanup_failed_venv(venv_path) in each of the failure scenarios.

This catch block is bare, which means any error details from the failed health check are swallowed. For better debugging, it's good practice to capture the error object and include it in the log. Using debugError would be appropriate here.

venv breaks when symlinked" with a note that symlinking is supported for
venv/.venv but a post-symlink health check is performed and, on failure, the
system falls back to recreating the venv (aligning the docstring with the
mapping in dependency_strategy.py where SYMLINK is applied to venv/.venv and the
module docstring describes the health-check strategy).

chain so the final strategy_name reflects any fallback. Concretely: when the
subprocess/OSError except block calls _apply_recreate_strategy (and sets
performed), also update strategy_name to the recreate strategy (or allow
strategy_name to be reassigned by that call) and move the results bookkeeping
that appends to results[] to after the full venv/venv-symlink/clone handling so
the recorded entry uses the possibly-updated strategy_name (referencing

There was a problem hiding this comment.
Test name and docstring are misleading — the venv will actually be recreated, not symlinked.
The test test_venv_symlinked_when_source_exists states "Venv is symlinked (not recreated) when source venv exists." However, the fake venv has no Python binary, so the health check will always fail and the code will fall back to recreate. The assertion target.exists() or target.is_symlink() passes in both cases, masking what actually happened.
Consider either:
- Mocking
subprocess.runfor the health check to make it pass, confirming the symlink path works end-to-end, or - Renaming the test to reflect what it actually verifies (e.g.,
test_venv_exists_after_setup_regardless_of_strategy).

🧹 Nitpick | 🔵 Trivial
Fallback smoke test is reasonable but weak.
test_venv_health_check_fallback_to_recreate only asserts isinstance(results, dict), which verifies the code doesn't crash but doesn't confirm the fallback actually occurred. Consider asserting that the result contains the .venv path (indicating recreate succeeded), or patching _apply_recreate_strategy to verify it was called.

🔵 [e19dbecadab6] [LOW] Missing recursive flag in symlink removal during health check fallback
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:382
In the TypeScript health check fallback path (line 382), rmSync is called with only { force: true } when removing a broken symlink/junction before falling back to recreate. Every other rmSync call for venv paths in this same file uses { recursive: true, force: true } (lines 476, 510, 555). The Python equivalent properly differentiates between symlinks (unlink()) and directories (shutil.rmtree()). While this doesn't cause a bug in practice — the catch block silences failures, and the subsequent applyRecreateStrategy handles cleanup with { recursive: true, force: true } (line 476) — it creates an unnecessary failure-and-recovery cycle on Windows where junctions/symlinks-to-directories may require recursive: true in some Node.js versions.
Suggested fix:
Add `recursive: true` for consistency: `try { rmSync(path.join(worktreePath, config.sourceRelPath), { recursive: true, force: true }); } catch { /* best-effort */ }`
🟡 [a89c1a099f57] [MEDIUM] Unguarded symlink removal skips recreate fallback on failure
📁 apps/backend/core/workspace/setup.py:660
In the Python health check fallback path (setup.py lines 659-666), symlink_path.unlink() is NOT wrapped in a try/except. If it raises an error (e.g., PermissionError on Windows when a junction is locked by another process), the exception propagates out of the except (subprocess.SubprocessError, OSError) handler at line 653, gets caught by the outer except Exception at line 677, and _apply_recreate_strategy() is never called. The worktree ends up with no usable venv and no fallback attempt.
The TypeScript version correctly wraps the equivalent rmSync call in try/catch (line 382), ensuring applyRecreateStrategy always executes regardless of whether symlink removal succeeded.
Triggering scenario:
- Symlink is created successfully
- Health check fails (SubprocessError/OSError caught)
symlink_path.unlink()raises PermissionError (Windows file lock)- PermissionError propagates → caught by outer
except Exception _apply_recreate_strategyis never called- Dependency setup silently fails — no venv in worktree
Suggested fix:
Wrap the symlink removal in a try/except to match the TypeScript implementation:
```python
try:
if symlink_path.is_symlink():
symlink_path.unlink()
elif symlink_path.exists():
shutil.rmtree(symlink_path, ignore_errors=True)
except OSError:
pass # Best-effort removal; recreate strategy handles existing paths
performed = _apply_recreate_strategy(
project_dir, worktree_path, config
)
This ensures the recreate fallback always executes, and _apply_recreate_strategy already handles the case where the path still exists (lines 793-802).

Verdict
CI status: ✅ All 20 checks passing — no CI blockers.
Both previous findings from the last review have been properly resolved:
- [e19dbecadab6] rmSync now uses { recursive: true, force: true } and is wrapped in try/catch ✅
- [a89c1a099f57] symlink_path.unlink() is now wrapped in try/except OSError ✅
However, 2 new MEDIUM-severity issues were identified and validated as genuine:
-
NEW-001 [MEDIUM]:
_popen_with_cleanup()usesproc.wait()instead ofproc.communicate()after terminate/kill, which per Python documentation can deadlock with piped stdout/stderr and leaks pipe file descriptors. Fix: replaceproc.wait()withproc.communicate()on both timeout-handler lines. -
CMT-002 [MEDIUM]: Venv health check is skipped on re-runs because
_apply_symlink_strategy()returns False when the symlink already exists, and the health check is guarded byif performed. If the source venv breaks between runs, the broken symlinked venv goes undetected. Fix: run the health check whenever a venv symlink exists, not only when freshly created.
Additionally, 2 LOW-severity issues were confirmed (non-blocking):
- NEW-002: Fallback-to-recreate result is logged under 'symlink' strategy name (cosmetic)
- NEW-003: DependencyStrategy docstring in models.py still says "Python venv breaks when symlinked", contradicting the new symlink-first behavior
1 finding (CMT-001 - sys.prefix not validated) was dismissed as a false positive: validating sys.prefix against the worktree path would cause false failures since symlinks intentionally point to the original venv.
Good progress — the author addressed both previous findings thoroughly. The 2 MEDIUM issues should be straightforward to fix.

🟡 [NEW-001] [MEDIUM] Pipe resource leak and potential deadlock in _popen_with_cleanup timeout path
📁 apps/backend/core/workspace/setup.py:776
After communicate() raises TimeoutExpired, the function calls proc.wait() (lines 776, 780) instead of proc.communicate() to drain pipe buffers. Python docs explicitly warn that proc.wait() with stdout=PIPE/stderr=PIPE can deadlock if the child writes enough to fill the OS pipe buffer. Pipe file descriptors are also leaked until garbage collection. This affects the pip install path (timeout=300s) which can produce substantial output.
Suggested fix:
Replace proc.wait(timeout=10) with proc.communicate(timeout=10) and proc.wait(timeout=5) with proc.communicate(timeout=5) in the TimeoutExpired handler.
🟡 [CMT-002] [MEDIUM] Venv health check skipped when symlink already exists on re-run
📁 apps/backend/core/workspace/setup.py:635
When _apply_symlink_strategy() returns False (symlink already exists), performed is False, and the health check at 'if performed and config.dep_type in ("venv", ".venv")' is skipped entirely. If the source venv is corrupted or deleted between worktree setup runs, the broken symlinked venv goes undetected silently.
Suggested fix:
Decouple the health check from the 'performed' flag. Run the health check whenever a venv symlink exists at the target path, not only when freshly created. For example: check if target is a symlink and dep_type is venv, regardless of whether _apply_symlink_strategy created it.
🔵 [NEW-002] [LOW] Venv fallback-to-recreate logged under 'symlink' strategy name
📁 apps/backend/core/workspace/setup.py:679
When a venv symlink health check fails and falls back to _apply_recreate_strategy(), the result is recorded under results['symlink'] because strategy_name is never updated. The user sees 'Dependencies (symlink): .venv' even though the venv was recreated.
Suggested fix:
After falling back to recreate, update strategy_name to 'recreate' or record under the correct key in the results dict.
🔵 [NEW-003] [LOW] DependencyStrategy docstring contradicts new symlink-first behavior
📁 apps/backend/core/workspace/models.py:278
The DependencyStrategy class docstring says 'Python venv breaks when symlinked' and warns about 'import failures and broken interpreters', which contradicts the new default of SYMLINK strategy for venvs. The dependency_strategy.py module docstring was updated but models.py was not.
Suggested fix:
Update the DependencyStrategy docstring in models.py to reflect the new symlink-first-with-fallback approach, consistent with the updated dependency_strategy.py narrative.

the python_exec variable, _popen_with_cleanup call, and venv_path so you add the
new exception handler adjacent to the existing subprocess.TimeoutExpired
handler.
In `@apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts`:
- Around line 368-385: The health-check is incorrectly gated on the local
variable `performed`, so existing symlinked venvs that become broken later are
never re-validated; remove the `performed &&` condition and instead check
whether the venv path actually exists or is a symlink before running the exec
health check. Add a small helper (e.g., `existsOrIsSymlink`) that uses
`existsSync`/`lstatSync` semantics to detect presence or symlink, then change
the `if` around the `execFileAsync` block to `if ((config.depType === 'venv' ||
config.depType === '.venv') && existsOrIsSymlink(venvPath))` so the
`execFileAsync`/`debugLog`/`applyRecreateStrategy` flow still runs when a
pre-existing symlink is present but broken.
- Around line 563-564: The catch block that swallows errors when writing the
completion marker (writeFileSync(markerPath, '')) should at minimum log the
caught error for debugging; update the anonymous catch in the
worktree-handlers.ts section around writeFileSync to catch the error into a
variable and call the existing debug logging utility (e.g., debugLog or
processLogger.debug) with a concise message including markerPath and the error,
so failures to write the marker are visible during debugging without changing
failure semantics.

Verdict
CI status: ✅ All 20 checks passing — no CI blockers.
2 of 4 previous findings have been properly resolved:
- [NEW-001] Pipe resource leak/deadlock: FIXED — proc.communicate() now used instead of proc.wait() after terminate/kill.
- [CMT-002] Venv health check skipped on re-run: FIXED in backend — health check decoupled from
performedflag, runs whenever venv symlink exists.
2 previous findings remain unresolved (both LOW severity):
- [NEW-002] Strategy name not updated when falling back from symlink to recreate — misleading user output.
- [NEW-003] DependencyStrategy docstring in models.py still says "Python venv breaks when symlinked", contradicting the new symlink-first default.
3 new blocking issues found and confirmed valid:
- [HIGH] Frontend health check gated on
performedflag (worktree-handlers.ts:369), inconsistent with backend's decoupled logic. Pre-existing broken venv symlinks will not be detected on the frontend path. - [MEDIUM] Backend
_apply_recreate_strategyusesvenv_path.exists()which follows symlinks — broken symlinks return False and are not cleaned up, blocking future venv creation. - [MEDIUM] Frontend
applyRecreateStrategyhas the same broken-symlink detection issue usingexistsSync.
1 finding dismissed as false positive:
- Pipe FD leak after proc.kill() — SIGKILL is unblockable on POSIX, and Python's GC closes pipe FDs. Not a realistic concern.
The HIGH-severity frontend inconsistency is the most important fix: the backend was correctly updated to decouple the health check, but the frontend still gates on performed, defeating the purpose of the fix for terminal-initiated worktree setups.

This is an AI-generated follow-up review using parallel specialist analysis with finding validation.
Findings (7 selected of 7 total)
🔵 [NEW-002] [LOW] [UNRESOLVED] Venv fallback-to-recreate logged under 'symlink' strategy name
📁 apps/backend/core/workspace/setup.py:679
When a venv symlink health check fails and falls back to _apply_recreate_strategy(), the result is recorded under results['symlink'] because strategy_name is never updated. The user sees 'Dependencies (symlink): .venv' even though the venv was recreated.
Resolution note: Line 626: strategy_name = config.strategy.value (set to 'symlink'). Lines 670-671: performed = _apply_recreate_strategy(...) after fallback. Line 682: results[strategy_name].append(...) records result under 'symlink'. strategy_name is never updated to 'recreate' when falling back.
Suggested fix:
After falling back to recreate, update strategy_name to 'recreate' or record under the correct key in the results dict.
🔵 [NEW-003] [LOW] [UNRESOLVED] DependencyStrategy docstring contradicts new symlink-first behavior
📁 apps/backend/core/workspace/models.py:278
The DependencyStrategy class docstring says 'Python venv breaks when symlinked' and warns about 'import failures and broken interpreters', which contradicts the new default of SYMLINK strategy for venvs. The dependency_strategy.py module docstring was updated but models.py was not.
Resolution note: models.py lines 281-287: docstring still reads 'Python venv breaks when symlinked because CPython's pyvenv.cfg discovery walks the real directory hierarchy without resolving symlinks first (CPython bug #106045)... causing import failures and broken interpreters.' dependency_strategy.py was updated but models.py was not.
Suggested fix:
Update the DependencyStrategy docstring in models.py to reflect the new symlink-first-with-fallback approach, consistent with the updated dependency_strategy.py narrative.
🟠 [NCR-001] [HIGH] Frontend health check gated on 'performed' — inconsistent with backend's decoupled logic
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:369
The backend health check (setup.py:636-639) runs whenever a venv symlink exists, regardless of whether _apply_symlink_strategy just created it. The frontend at line 369 gates on 'if (performed && ...)', meaning when applySymlinkStrategy returns false (symlink already exists from a previous run), the health check is skipped entirely. Pre-existing broken venv symlinks in terminal-initiated worktrees will never be detected or repaired. This defeats the purpose of the CMT-002 fix applied to the backend.
Suggested fix:
Change line 369 from 'if (performed && (config.depType === ...))' to check venv path existence independently: 'if (config.depType === 'venv' || config.depType === '.venv') { const venvPath = path.join(worktreePath, config.sourceRelPath); if (existsSync(venvPath)) { /* run health check */ } }'
🟡 [NCR-003] [MEDIUM] Broken symlinks invisible to _apply_recreate_strategy cleanup
📁 apps/backend/core/workspace/setup.py:799
_apply_recreate_strategy uses venv_path.exists() (line 799) which follows symlinks — a broken symlink returns False, so the incomplete-venv cleanup is skipped. If a broken symlink persists at the path (e.g., from a failed previous setup), python -m venv fails because the symlink still occupies the filesystem entry. When called from the symlink fallback path this is mitigated (lines 661-669 clean up first), but when called directly from the RECREATE strategy branch, broken symlinks are not handled.
Suggested fix:
Change line 799 from 'if venv_path.exists():' to 'if venv_path.exists() or venv_path.is_symlink():' and handle the symlink case by unlinking it before proceeding with recreation.
🟡 [NCR-005] [MEDIUM] Frontend applyRecreateStrategy does not detect broken symlinks
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:469
Same issue as NCR-003 in the frontend. existsSync(venvPath) at line 469 follows symlinks — a broken symlink returns false, skipping cleanup. The function lacks a lstatSync check (unlike applySymlinkStrategy at lines 426-432 which already handles broken symlinks correctly).
Suggested fix:
Add a broken-symlink check before the existsSync check: try { lstatSync(venvPath); } catch { /* truly absent */ }. If lstat succeeds but existsSync fails, the entry is a broken symlink and should be removed.
🔵 [NCR-004] [LOW] Venv creation try/except missing OSError catch, inconsistent with pip install block
📁 apps/backend/core/workspace/setup.py:839
The venv creation try/except (lines 823-846) only catches subprocess.TimeoutExpired. If python_exec doesn't exist, FileNotFoundError propagates to the outer except Exception handler which only logs a debug warning — no user-facing warning via print_status. The pip install block at lines 909-913 correctly catches both TimeoutExpired and OSError, making this an internal inconsistency.
Suggested fix:
Add 'except OSError as e:' after the TimeoutExpired handler, matching the pip install block pattern: log via debug_warning and print_status, clean up partial venv, return False.
🟡 [CMT-001] [MEDIUM] [FROM COMMENTS] Frontend health check inconsistency flagged by both Sentry and CodeRabbit
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:369
Both @sentry[bot] and CodeRabbit independently identified that the frontend health check is gated on 'performed' (line 369), inconsistent with the backend's decoupled logic. The backend was fixed in commit fd09f87 but the frontend was not updated to match. This was the highest-confidence finding from the comment analysis, corroborated by two independent AI tools. Merged with NCR-001.
Suggested fix:
Mirror the backend pattern: check venv path existence independently of the performed flag.

Verdict
All 20 CI checks are passing. All 7 previous findings have been resolved — excellent progress addressing review feedback. However, 2 new confirmed issues were identified:
-
[HIGH] KeyError on venv symlink fallback path (NEW-001): When a venv symlink health check fails and the fallback recreate succeeds,
strategy_nameis changed to"recreate"butresults["recreate"]was never initialized, causing aKeyErroratresults[strategy_name].append(...). While the outerexcept Exceptionprevents a crash, it silently drops the successful recreate result and logs a misleading warning. This was independently flagged by both the new-code-reviewer and CodeRabbit. One-line fix:results.setdefault(strategy_name, []).append(...). -
[MEDIUM] isSymlinkOrJunction doesn't detect Windows junctions (NEW-002): The function only checks
lstatSync().isSymbolicLink()which returnsfalsefor Windows junctions, butapplySymlinkStrategycreates junctions on Windows viasymlinkSync(..., 'junction'). Broken junctions won't be detected during health checks on Windows.
Both HIGH and MEDIUM findings are confirmed valid and should be addressed before merge. The fixes are straightforward (one-liner for NEW-001, small refactor for NEW-002).

Findings (4 selected of 4 total)
🟠 [NEW-001] [HIGH] KeyError when venv symlink falls back to recreate strategy
📁 apps/backend/core/workspace/setup.py:685
When a venv symlink health check fails and the fallback to recreate succeeds, strategy_name is updated to 'recreate' (line 675) but results['recreate'] was never initialized. The results dict is only initialized with the original strategy key 'symlink' (lines 627-628). When line 685 executes results[strategy_name].append(...), it raises KeyError. While the outer except Exception prevents a crash, the successful recreate result is silently dropped and a misleading warning is logged.
Suggested fix:
Change line 685 from `results[strategy_name].append(config.source_rel_path)` to `results.setdefault(strategy_name, []).append(config.source_rel_path)`, or add `results.setdefault('recreate', [])` after line 675 where strategy_name is reassigned.
🟡 [NEW-002] [MEDIUM] isSymlinkOrJunction does not actually detect Windows junctions
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:64
The isSymlinkOrJunction function uses lstatSync().isSymbolicLink() which returns false for Windows junctions. However, applySymlinkStrategy creates junctions on Windows via symlinkSync(..., 'junction'). This means broken venv junctions on Windows are silently missed during health checks at lines 386 and 487, preventing automatic fallback to recreate.
Suggested fix:
Use readlinkSync in a try/catch instead of isSymbolicLink() — readlinkSync works for both symlinks and junctions. Alternatively, check for junctions by testing if the path exists via lstat but is broken (lstatSync succeeds but existsSync fails).
🔵 [NEW-003] [LOW] Potential resource leak if kill() followed by communicate() times out in _popen_with_cleanup
📁 apps/backend/core/workspace/setup.py:786
In _popen_with_cleanup, if proc.kill() followed by proc.communicate(timeout=5) also raises TimeoutExpired, the stdout/stderr pipes are not closed and the process may remain as a zombie. While extremely unlikely after SIGKILL on POSIX, a finally block would ensure deterministic cleanup.
Suggested fix:
Add a finally block or wrap the inner except in try/except to ensure proc.stdout.close(), proc.stderr.close(), and proc.wait() are called even if the final communicate() times out.
🔵 [CMT-002] [LOW] [FROM COMMENTS] Redundant variable symlink_path identical to venv_path
📁 apps/backend/core/workspace/setup.py:662
symlink_path = worktree_path / config.source_rel_path at line 662 computes the exact same value as venv_path defined at line 637. Both are in the same scope. symlink_path on lines 664-667 could be replaced with venv_path for clarity.
Suggested fix:
Replace symlink_path with venv_path on lines 662-667.

🧹 Nitpick | 🔵 Trivial
Health check correctly decoupled from performed — minor redundancy on line 400.
The health check now runs whenever a venv symlink/path exists regardless of whether a fresh symlink was just created. This addresses the prior review feedback.
One nit: line 400 rebuilds the path path.join(worktreePath, config.sourceRelPath), which is identical to venvPath already declared on line 386.
Use the existing `venvPath` variable
- try { rmSync(path.join(worktreePath, config.sourceRelPath), { recursive: true, force: true }); } catch { /* best-effort */ }

Findings (6 selected of 6 total)
🔵 [NEW-CODE-001] [LOW] performed=True default inconsistent with TypeScript performed=false
📁 apps/backend/core/workspace/setup.py:631
Python initializes performed = True before the strategy dispatch if/elif chain, while the TypeScript equivalent uses performed = false. If a new DependencyStrategy enum variant is added without updating the chain, the Python version would falsely record the path as successfully processed. Not an active bug since all 4 current strategies are handled.
Suggested fix:
Initialize `performed = False` to match the TypeScript implementation's safer default.
🔵 [NEW-CODE-002] [LOW] Misleading _popen_with_cleanup docstring about TimeoutExpired
📁 apps/backend/core/workspace/setup.py:767
Docstring states 'Raises subprocess.TimeoutExpired if the process could not be stopped' but the exception is always re-raised when the initial communicate() timeout is exceeded, regardless of whether cleanup succeeded.
Suggested fix:
Change docstring to: 'Raises subprocess.TimeoutExpired if the command exceeds the given timeout (after cleanup is attempted).'
🔵 [NEW-CODE-003] [LOW] applySymlinkStrategy uses lstatSync instead of new isSymlinkOrJunction helper
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:444
The new isSymlinkOrJunction helper (using readlinkSync) was added for reliable symlink/junction detection and is used in setupWorktreeDependencies and applyRecreateStrategy. However, applySymlinkStrategy still uses the older lstatSync approach. This is a minor consistency issue — both approaches work for detecting broken symlinks, but the dedicated helper should be used throughout.
Suggested fix:
Replace the lstatSync check at lines 444-451 with isSymlinkOrJunction(targetPath) for consistency.
🔵 [NEW-CODE-004] [LOW] TypeScript doesn't distinguish strategy in results when venv fallback occurs
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:397
When a venv symlink health check fails and falls back to recreate, the TypeScript version records the path in a flat processed array without noting the actual strategy used. The Python version explicitly changes strategy_name to 'recreate' and records under the correct key. This is a minor behavioral inconsistency affecting debug output.
Suggested fix:
Add a debug log like `debugLog('[TerminalWorktree] Venv fallback to recreate succeeded:', config.sourceRelPath)` after successful recreate.
🔵 [CMT-001] [LOW] [FROM COMMENTS] Redundant path.join reconstruction when venvPath is already in scope
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:400
Line 400 uses path.join(worktreePath, config.sourceRelPath) but venvPath with the identical value is already declared at line 386. Should reuse the existing variable for consistency.
Suggested fix:
Replace `path.join(worktreePath, config.sourceRelPath)` on line 400 with `venvPath`.
🟡 [CMT-002] [MEDIUM] [FROM COMMENTS] Broken symlinks for non-venv types persist indefinitely (from CodeRabbit)
📁 apps/frontend/src/main/ipc-handlers/terminal/worktree-handlers.ts:444
applySymlinkStrategy detects broken symlinks via lstatSync and returns false without removing them. For venv types, the health-check fallback handles this. For non-venv types (node_modules, vendor_php), a broken symlink persists forever. This is pre-existing behavior not introduced by this PR, but is worth addressing in a follow-up.
Suggested fix:
When a broken symlink is detected (lstatSync succeeds but existsSync fails), remove it before returning false so a fresh symlink can be created on retry.
