From 793e01ca9eae93ee730b40ed92caa26959bba635 Mon Sep 17 00:00:00 2001 From: nitrobass24 Date: Wed, 18 Mar 2026 16:05:12 -0500 Subject: [PATCH] Fix 86 Pyright errors in security-critical paths (#249 Phase 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Type-only changes, no behavior modifications. Reduces Pyright error count from 149 to 64. Files fixed: - lftp/lftp.py (33) — pexpect spawn null guards, descriptor pattern type ignores, env dict cast, kill() None handling - ssh/sshcp.py (19) — pexpect before/after narrowing with isinstance guards, replacing != pexpect.EOF checks Pyright couldn't narrow - controller/extract/extract_process.py (14) — datetime module vs class confusion, Optional params, dispatch null guard - web/web_app.py (13) — Bottle DictProperty type ignores on route decorators - controller/auto_queue.py (7) — cls TypeVar fix, None guard on pair_id dict lookup, shadowed variable rename Co-Authored-By: Claude Opus 4.6 (1M context) --- src/python/controller/auto_queue.py | 10 ++-- .../controller/extract/extract_process.py | 22 ++++---- src/python/lftp/lftp.py | 54 +++++++++++-------- src/python/ssh/sshcp.py | 36 ++++++++----- src/python/web/web_app.py | 26 ++++----- 5 files changed, 86 insertions(+), 62 deletions(-) diff --git a/src/python/controller/auto_queue.py b/src/python/controller/auto_queue.py index f3c0928d..05b33709 100644 --- a/src/python/controller/auto_queue.py +++ b/src/python/controller/auto_queue.py @@ -88,8 +88,8 @@ def add_listener(self, listener: IAutoQueuePersistListener): @classmethod @overrides(Persist) - def from_str(cls: "AutoQueuePersist", content: str) -> "AutoQueuePersist": - persist = AutoQueuePersist() + def from_str(cls: type["AutoQueuePersist"], content: str) -> "AutoQueuePersist": + persist = cls() try: dct = json.loads(content) pattern_list = dct[AutoQueuePersist.__KEY_PATTERNS] @@ -356,6 +356,8 @@ def _is_auto_queue_enabled_for_file(self, file: ModelFile) -> bool: caller (process()) already gates on the global __enabled flag.
