stage-257 batch (PRs #1402 + #1415):
Opus pre-release advisor caught 4 issues in stage-257:
1. MUST-FIX (security): api/oauth.py::_write_auth_json — tmp.replace()
preserves the temp file umask (0644 default), so OAuth access/refresh
tokens landed world-readable on shared systems. Fix: tmp.chmod(0o600)
BEFORE rename, with try/except OSError that warns but does not abort.
2. SHOULD-FIX: _handle_cron_history and _handle_cron_run_detail accepted
job_id as a path component without validation. Mirrors the rollback
path-traversal vector caught in v0.50.255 (#1405). Path() / .. does NOT
normalize. New regex ^[A-Za-z0-9_-][A-Za-z0-9_.-]{0,63}$ with explicit
. / .. rejection.
3. SHOULD-FIX: _handle_cron_history int(offset)/int(limit) raised
ValueError on malformed input → confusing 500. Now try/except + clamp
to (max(0, offset), max(1, min(500, limit))).
4. NIT: same regex applied to _handle_cron_run_detail (defense-in-depth
even though path-resolve check would catch it downstream).
PR #1415 follow-up: 8 pre-existing tests in test_issue1106 and
test_custom_provider_display_name asserted bare model IDs but #1415
changes named-custom-provider IDs to @custom:NAME:model form when active
provider differs. Tests updated to use _strip_at_prefix helper to keep
checking the same invariant in the new shape.
4 regression tests in test_v050257_opus_followups.py + 8 fixed pre-existing
tests. Full suite: 3602 passed, 0 failed.
* fix(#1096): copy buttons fall back to execCommand on HTTP contexts
- Add _copyText() helper: tries navigator.clipboard first, falls back to
document.execCommand('copy') with hidden textarea when not in secure context
- Update copyMsg() and addCopyButtons() to use helper instead of direct
navigator.clipboard.writeText()
- Code block copy button now has .catch() handler (was silently failing)
- Error messages use t('copy_failed') for i18n instead of hardcoded string
- Add copy_failed key to all 6 locale blocks (en, ru, es, de, zh, zh-Hant)
- Add 10 regression tests
* fix(#1095): render pasted/dragged images as inline preview instead of paperclip badge
- User message attachments with image extensions now render as <img> via
api/media endpoint, with click-to-fullscreen support
- Non-image attachments still show paperclip + filename badge
- Extracts filename from full path for display
- Add 5 regression tests
* fix: hoist _IMAGE_EXTS to module scope, add avif (absorb fix)
* fix: improve mobile touch responsiveness for session list items
iPad Safari has known issues with the click/dblclick pattern on touch:
- :hover-triggered padding-right layout shift causes the first tap click
to target the wrong element (actions button that just appeared)
- No touch-action:manipulation means iOS still delays taps for
double-tap zoom detection
- The old onclick+ondblclick pattern is designed for mouse, not touch
Changes:
- CSS: Remove :hover from padding-right rule to prevent layout shift
- CSS: Add touch-action:manipulation and -webkit-tap-highlight-color
to .session-item for immediate tap response
- JS: Replace onclick/ondblclick with onpointerup + manual 350ms
double-tap detection — works consistently on mouse and touch
* fix(#1106): iterate custom_providers[].models dict keys for dropdown population
- After reading singular 'model' field, also iterate 'models' dict keys
- Deduplicate: model field value not repeated if also in models dict
- Skip non-string keys gracefully
- Works for both named and unnamed custom_providers entries
- Add 7 regression tests
* fix(#1105): allow custom_providers hostnames through SSRF check
- Build trusted hostname set from custom_providers[].base_url in config.yaml
- These are user-explicitly configured endpoints — not SSRF risks
- Hardcoded allowlist (ollama, localhost, 127.0.0.1, lmstudio) still active
- Unknown private IPs still blocked
- Add 7 tests (5 source analysis + 2 functional with mocked socket)
* fix(tests): update hover padding assertions for #1110 touch fix (absorb)
* fix(css): restore hover padding via @media (hover:hover) for mouse devices (absorb)
* fix: filter right/middle-click from pointerup handler (absorb)
* docs: v0.50.221 release notes and version bump
