Off Linux that file is always missing, so the branch always fired: the pid file of a live daemon was deleted and the daemon itself never killed. _owned_daemon_exists() swallowed the same error and therefore always returned False, which is precisely the state its own docstring warns about, since a close against an unrecognised session can bootstrap a fresh daemon and wait on its browser indefinitely. Demonstrated on macOS before the change: a pid file holding a live pid is removed by _terminate_owned_daemon() and _owned_daemon_exists() reports False. After it, the file survives and the daemon is reported present. _process_command_line() now returns None for "this host cannot tell" and _process_is_alive() answers the separate question of whether the pid exists. Without procfs we decline to kill a process we cannot confirm is ours, and we only forget a pid file once the pid is genuinely gone. Linux behaviour is unchanged: the command-line identity check still gates both paths. --- src/agent_tools/web_tools.py | 66 ++++++++++++++++++++----- tests/test_private_browser_tool.py | 78 ++++++++++++++++++++++++++++++ 2 files changed, 131 insertions(+), 13 deletions(-) diff --git a/src/agent_tools/web_tools.py b/src/agent_tools/web_tools.py index 84bce8d5c..8c8a98621 100644 --- a/src/agent_tools/web_tools.py +++ b/src/agent_tools/web_tools.py @@ -125,6 +125,37 @@ def _browser_pid_file_candidates( # host that has no procfs, and on one that does. _PROC_ROOT = Path("/proc") + +def _process_command_line(pid: int) -> str | None: + """Command line of a running process, or ``None`` when it cannot be read. + + ``None`` means "this host cannot tell", not "the process is gone".

They now live in routes/email/, following the pattern fifteen route areas already use: the canonical module under the package, a shim at the old path that replaces itself in sys.modules with the canonical object. The shim matters more here than the move. Dozens of email tests monkeypatch module attributes, and several pop the module from sys.modules and re-import it. Without identity between routes.email_routes and routes.email.email_routes those patches would apply to a different object than the app uses. Intra-package imports keep the flat path, matching routes/document/ and routes/gallery/: the shim resolves them and the diff stays a move. Eight path references in five test modules read these files as source rather than importing them, so they now read the canonical location. That is the same adjustment every previous conversion made, and it is why the note/document shims mention source-introspection tests explicitly. No behaviour change. Verified with the full suite and under several explicit collection orders, since a byte-identical routes move has broken tests under one ordering before. --- routes/email/__init__.py | 8 + routes/email/email_helpers.py | 2025 ++++++ routes/email/email_pollers.py | 1764 ++++++ routes/email/email_routes.py | 7194 +++++++++++++++++++++ routes/email_helpers.py | 2031 +----- routes/email_pollers.py | 1770 +----- routes/email_routes.py | 7200 +--------------------- tests/test_action_menu_order.py | 6 +- tests/test_direct_upload_limits.py | 2 +- tests/test_email_library_bulk_actions.py | 2 +- tests/test_imap_mailbox_quoting.py | 2 +- tests/test_upload_limits_centralized.py | 4 +- 12 files changed, 11032 insertions(+), 10976 deletions(-) create mode 100644 routes/email/__init__.py create mode 100644 routes/email/email_helpers.py create mode 100644 routes/email/email_pollers.py create mode 100644 routes/email/email_routes.py diff --git a/routes/email/__init__.py b/routes/email/__init__.py new file mode 100644 index 000000000..e2bb80229 --- /dev/null +++ b/routes/email/__init__.py @@ -0,0 +1,8 @@ +"""Email route domain package. + +Contains email_routes.py, email_helpers.py and email_pollers.py, migrated +from the flat routes/ directory.
