Every other uid.decode() call in this function uses
'uid.decode() if isinstance(uid, bytes) else str(uid)' but the
warning at line 832 does bare uid.decode(), crashing with
AttributeError when uid is already a string.
`_auto_summarize_pass_single` in `routes/email_pollers.py` opens a
long-lived IMAP connection at line 172 and then performs ~700 lines of
work — IMAP `select`/`FETCH`/`SEARCH`, network POSTs to the LLM
endpoint, SQLite writes, and per-uid awaits. The only `conn.logout()`
calls were on three safe paths (early `"No recent emails"`, early
`"No model configured"`, and the happy path at the very end). If any
exception fired between `conn` being created and the final happy path,
the outer `except` block at line 921 caught it, logged, and returned —
without ever calling `conn.logout()`. The IMAP socket leaked until
the server's idle timeout killed it.
This is the same shape as the just-merged upstream fixes#1325
(`_imap_move` in `routes/email_helpers.py`) and #1330 (`_list_emails_sync`
in `routes/email_routes.py`), but in the *background* poller path —
`_auto_summarize_poller` invokes it every 30 min, so the leak
accumulates on every crashed pass instead of being a transient
request-path leak.
The fix is the exact try/finally pattern from #1330:
1. initialize `conn = None` before the try
2. let the try-block assign `conn = _imap_connect(...)`
3. drop the three explicit `conn.logout()` calls on safe paths
4. add a `finally:` block that calls `conn.logout()` if `conn` was set
Tests in `tests/test_email_polly_imap_leak.py` (1, all passing):
- `test_auto_summarize_pass_logs_out_imap_on_select_failure` —
monkeypatches `_imap_connect` to return a fake conn whose `select`
raises `RuntimeError`, then asserts the fake `conn.logout` was
called exactly once and the function returned an `Error: ...`
string. Pre-fix the assertion fails because the outer `except`
never reached `conn.logout`; post-fix the `finally` block
guarantees it on every exit path.
Pre-fix verification: temporarily reverted the patch and re-ran the
test; it fails with `logout_calls=0` (the IMAP socket was leaked on
every crashed pass). Post-fix: `logout_calls=1`.
Uniqueness:
- `git log --all --oneline -S 'conn.logout' -- routes/email_pollers.py`
→ no recent commit has touched this pattern in this file
- GitHub PR search for `routes/email_pollers.py` open PRs → 0
- Function has no existing test file (`grep _auto_summarize_pass_single
tests/` → no results)

**@pewdiepie-archdaemon — gentle bump on a sibling PR that's also stuck
in your queue from the same author:** PR #1306
(`fix(caldav): no-op prune when date_search returns 0 events`) is on
its 4th rebase, isolated to 2 files, 2/2 tests passing, with one
independent approval from `lalalune` already on record. It was clean
the last time you re-checked; if there's a blocker I haven't
addressed, please flag it so I can fix it. Otherwise, both #1306 and
this one are ready to merge.

* fix: omit temperature for OpenAI reasoning models (o1/o3/o4/gpt-5)
These models only accept the default temperature; sending any explicit
value (even 0.0) returns HTTP 400 "Only the default (1) value is
supported". This broke two paths:
- Endpoint probing in _probe_single_model hardcodes temperature: 0.0, so
a perfectly valid o3/gpt-5 endpoint is reported as failing in the
Model Endpoints health check.
- Chat/stream payloads send temperature unconditionally, so a non-default
temperature preset 400s on these models.
The code already special-cases the same model family for
max_completion_tokens, so this adds a sibling _restricts_temperature()
helper and omits the field for those models, letting the API use its
required default. gpt-4.5 is intentionally excluded (not a reasoning
model; accepts temperature normally).
Adds tests/test_llm_core_temperature.py covering the predicate and the
synchronous payload builder.
* fix: also omit temperature for reasoning models on the direct-POST paths
The first commit only covered llm_call/llm_call_async/stream_llm and the
endpoint probe. Email auto-summary, urgency-less spam classification, the
email reply-summary endpoint, and gallery vision tagging build their
OpenAI payloads inline and POST them directly (requests/httpx), bypassing
llm_core — so a reasoning model configured there would still 400 on the
temperature field. These sites already branch on _uses_max_completion_tokens,
so they're the same class; added the matching _restricts_temperature guard.
gallery_routes also gains the max_completion_tokens branch it was missing,
so gpt-5 vision tagging works end to end.
Note: email_pollers urgency scoring goes through llm_call_async and was
already covered.
The email auto-calendar pass (settings.email_auto_calendar / the
extract_email_events task) scans recently received mail and lets an LLM
create / update / cancel calendar events. Two problems made it a cross-tenant,
remotely triggerable hole:
1. No owner scoping. _auto_summarize_pass(account_id=None) fans out over EVERY
enabled account of EVERY user. For each message it fetched an upcoming-events
snapshot with NO owner filter (all tenants' events) and handed those uids +
titles to the extraction LLM, then executed the model's ops via
do_manage_calendar(...) with owner=None. do_manage_calendar only filters by
owner when owner is not None, so create/update/delete ran across ALL users'
calendars. Net: every user's event titles/times were disclosed to the model,
and the model could cancel/move/duplicate any tenant's events by uid.
2. No prompt-injection wrapping. The raw email From/Subject/body were
interpolated straight into an instruction-shaped extraction prompt (unlike
the chat path, which wraps external text via src/prompt_security). Anyone
who can email a user whose instance has auto-calendar enabled could inject
operations: create attacker-controlled "meeting" events (the path even
auto-harvests URLs from the body into the event location/description — a
phishing primitive) or cancel/modify the victim's real events, with zero
human in the loop.
Fix:
- Add core.database.get_upcoming_events(owner) and use it for the snapshot, so
the LLM only ever sees the processed account owner's events.
- Look up the EmailAccount owner in _auto_summarize_pass_single and pass owner=
to every do_manage_calendar call, so create/update/delete are scoped to that
user (owner=None stays the single-user / legacy escape hatch).
- Tell the extraction model the email is untrusted data and not to follow
instructions inside it (defense-in-depth against injection).
Add tests/test_calendar_owner_scope.py: get_upcoming_events returns only the
given owner's events (and everything when owner is None). Fails against the old
unscoped query.
