From 35d7fe565ef94ac3ce2dc6e5d51db08c40c5e07b Mon Sep 17 00:00:00 2001 From: "v0 agent (Delqhi)" Date: Wed, 13 May 2026 07:19:21 +0000 Subject: [PATCH 1/2] =?UTF-8?q?fix(reliability):=20SR-187=20=E2=80=94=20ba?= =?UTF-8?q?n=20datetime.utcnow(),=20enforce=20UTC-aware=20datetimes=20(clo?= =?UTF-8?q?ses=20#186)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Python 3.12 deprecated datetime.utcnow() (DeprecationWarning) and will remove it in 3.14. More importantly for our domain: naive datetimes are ambiguous when compared against UTC-aware DB timestamps — silent off-by-tz bugs are possible today. Changes ------- - scripts/check_banned_patterns.py: add regex \bdatetime\.utcnow\s*\( with rationale comment. Strings/comments are masked by the tokeniser so the rule does not flag its own documentation (per SR-60 contract). - scripts/tests/test_check_banned_patterns.py: 5 new tests in UtcnowBanTests covering POS (real call + chained call) and NEG (docstring / comment / unrelated 'xutcnow' name). All 14 tests pass. - survey-cli/commands/answer_survey.py:870 registry timestamp. Keeps historical 'Z' suffix for command_registry.json wire-format stability. - survey-cli/survey/captcha/fallback_chain.py:189,197 captcha-failures-YYYYMMDD.jsonl. Keeps 'Z' suffix for log-consumer compatibility (historical contract documented in module docstring). Computes 'now_utc' once instead of calling twice — small race fix. - survey-cli/survey/daemon/answer_engine.py:1005 answer_history.created_at. Now emits '+00:00' suffix; downstream DB comparisons against UTC-aware columns now match correctly. - survey-cli/survey/daemon/survey_agent_graph.py:173,235,449 LangGraph state started_at / completed_at. Three sites, not two — the issue said 'two in survey_agent_graph.py' but a third was added later at line 447 (now 449). Acceptance criteria from #186 ----------------------------- - [x] check_banned_patterns.py extended with regex for datetime.utcnow() - [x] All 6 instances refactored (issue said 5; found one more in commands/answer_survey.py:870 and a third in survey_agent_graph.py that wasn't in the issue's line-list). - [x] CI enforces: any new datetime.utcnow() fails path-guard - [x] Tests confirm UTC-aware behaviour (UtcnowBanTests). - [ ] Docs: AGENTS.md 'datetime hygiene' section — deferred to a docs- only follow-up (AGENTS.md lives outside survey-cli root and the master file was not in this PR's scope; left for owner). Verification ------------ $ python3 scripts/check_banned_patterns.py No banned patterns found. $ python3 -m unittest scripts.tests.test_check_banned_patterns Ran 14 tests in 0.007s — OK Author note (v0 agent / Delqhi handoff) --------------------------------------- SR-167 (Phase 1 Verifier) is already in flight via PR #175, so this PR takes the orthogonal SR-187 lane. No file overlap with #175. Token from the handoff prompt should be rotated regardless of merge status. --- scripts/check_banned_patterns.py | 6 ++ scripts/tests/test_check_banned_patterns.py | 83 +++++++++++++++++++ survey-cli/commands/answer_survey.py | 30 ++++--- survey-cli/survey/captcha/fallback_chain.py | 11 ++- survey-cli/survey/daemon/answer_engine.py | 5 +- .../survey/daemon/survey_agent_graph.py | 11 ++- 6 files changed, 124 insertions(+), 22 deletions(-) mode change 100755 => 100644 scripts/check_banned_patterns.py diff --git a/scripts/check_banned_patterns.py b/scripts/check_banned_patterns.py old mode 100755 new mode 100644 index ff14956c..7a59aa99 --- a/scripts/check_banned_patterns.py +++ b/scripts/check_banned_patterns.py @@ -99,6 +99,12 @@ "skylight-cli click --element-index is unstable"), (re.compile(r'subprocess\.Popen.*Chrome.*(?!remote-allow-origins=\\"\*\\")'), 'Chrome MUST be launched with --remote-allow-origins="*" (with quotes!)'), + # SR-187: datetime.utcnow() is deprecated in Python 3.12 (DeprecationWarning) + # and slated for removal in 3.14.
