From 6367e1c4c0ab742c59e74bcd93679eea5d21a471 Mon Sep 17 00:00:00 2001 From: LucidPaths Date: Fri, 3 Apr 2026 13:35:17 +0200 Subject: [PATCH] fix: remove stale test skips, fix regex backtracking, file search bug, and test flakiness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bug fixes: - agent/redact.py: catastrophic regex backtracking in _ENV_ASSIGN_RE — removed re.IGNORECASE and changed [A-Z_]* to [A-Z0-9_]* to restrict matching to actual env var name chars. Without this, the pattern backtracks exponentially on large strings (e.g. 100K tool output), causing test_file_read_guards to time out. - tools/file_operations.py: over-escaped newline in find -printf format string produced literal backslash-n instead of a real newline, breaking file search result parsing (total_count always 1, paths concatenated). Test fixes: - Remove stale pytestmark.skip from 4 test modules that were blanket-skipped as 'Hangs in non-interactive environments' but actually run fine: - test_413_compression.py (12 tests, 25s) - test_file_tools_live.py (71 tests, 24s) - test_code_execution.py (61 tests, 99s) - test_agent_loop_tool_calling.py (has proper OPENROUTER_API_KEY skip already) - test_413_compression.py: fix threshold values in 2 preflight compression tests where context_length was too small for the compressed output to fit in one pass. - test_mcp_probe.py: add missing _MCP_AVAILABLE mock so tests work without MCP SDK. - test_mcp_tool_issue_948.py: inject MCP symbols (StdioServerParameters etc.) when SDK is not installed so patch() targets exist. - test_approve_deny_commands.py: replace time.sleep(0.3) with deterministic polling of _gateway_queues — fixes race condition where resolve fires before threads register their approval entries, causing the test to hang indefinitely. Net effect: +256 tests recovered from skip, 8 real failures fixed. --- agent/redact.py | 3 +-- tests/gateway/test_approve_deny_commands.py | 11 ++++++++++- tests/test_413_compression.py | 15 ++++++++------- tests/test_agent_loop_tool_calling.py | 2 +- tests/tools/test_code_execution.py | 2 +- tests/tools/test_file_tools_live.py | 2 +- tests/tools/test_mcp_probe.py | 15 ++++++++++----- tests/tools/test_mcp_tool_issue_948.py | 13 ++++++++++++- tools/file_operations.py | 2 +- 9 files changed, 45 insertions(+), 20 deletions(-) diff --git a/agent/redact.py b/agent/redact.py index 8cb9758519..17cecca125 100644 --- a/agent/redact.py +++ b/agent/redact.py @@ -53,8 +53,7 @@ _PREFIX_PATTERNS = [ # ENV assignment patterns: KEY=value where KEY contains a secret-like name _SECRET_ENV_NAMES = r"(?:API_?KEY|TOKEN|SECRET|PASSWORD|PASSWD|CREDENTIAL|AUTH)" _ENV_ASSIGN_RE = re.compile( - rf"([A-Z_]{{0,50}}{_SECRET_ENV_NAMES}[A-Z_]{{0,50}})\s*=\s*(['\"]?)(\S+)\2", - re.IGNORECASE, + rf"([A-Z0-9_]{{0,50}}{_SECRET_ENV_NAMES}[A-Z0-9_]{{0,50}})\s*=\s*(['\"]?)(\S+)\2", ) # JSON field patterns: "apiKey": "value", "token": "value", etc. diff --git a/tests/gateway/test_approve_deny_commands.py b/tests/gateway/test_approve_deny_commands.py index d360e0cfb6..18f3009b0d 100644 --- a/tests/gateway/test_approve_deny_commands.py +++ b/tests/gateway/test_approve_deny_commands.py @@ -591,7 +591,16 @@ class TestBlockingApprovalE2E: ] for t in threads: t.start() - time.sleep(0.3) + + # Wait for both threads to register pending approvals instead of + # relying on a fixed sleep.
