chore: remove dead code from previous #815 fix attempts

PR #840 fixed issue #815 in the Electron main process via will-prevent-unload + preventDefault. The renderer-side workarounds introduced by previous fix attempts (#642, #648) are no longer needed and never had effect for their stated purpose. Removed: - configuration={ confirmExit: false } in DrawIoEmbed confirmExit is not a recognized draw.io config key (zero matches in jgraph/drawio source). This was always dead code. - modified=0 / keepmodified=0 URL parameters Per drawio source (app.min.js:14898), these only suppress the post-save modified-flag clearing — they do not prevent edits from setting editor.modified=true. They were ineffective for blocking beforeunload prompts and actually prevented draw.io from clearing its modified flag after save. - canPersist / canPersistChecked state and isIndexedDBUsable() probe Their only purpose was gating the dead config above. Removing them also removes a startup delay before the iframe renders. - handleDrawioAutoSave wrapper After PR #780 stripped its body, it was a pure passthrough useCallback. Now passes handleDiagramAutoSave directly to onAutoSave. - withDB / isClosingError / resetDBPromise / onversionchange / onclose / terminated handlers in lib/session-storage.ts and lib/template-storage.ts PR #648 added these to recover from 'IDBDatabase: connection is closing' errors that PR #642's first land caused via db.close() on the shared singleton. That bug was already fixed in c5de1a1 (re-land of #642), three minutes before PR #648 commits started. The retry handlers defend against multi-tab / version-change scenarios that cannot occur in this single-instance Electron app (requestSingleInstanceLock). template-storage.ts copied the same pattern when introduced by #773. Verified: - npx tsc --noEmit passes - Manual test in dev mode: session save/load works, template create works, diagram-only persistence works.
fix(electron): override draw.io iframe beforeunload to allow window close (fixes #815 ) (#840 )

dayuan.jiang	2d43bcfb87	chore: remove dead code from previous #815 fix attempts PR #840 fixed issue #815 in the Electron main process via will-prevent-unload + preventDefault. The renderer-side workarounds introduced by previous fix attempts (#642, #648) are no longer needed and never had effect for their stated purpose. Removed: - configuration={ confirmExit: false } in DrawIoEmbed confirmExit is not a recognized draw.io config key (zero matches in jgraph/drawio source). This was always dead code. - modified=0 / keepmodified=0 URL parameters Per drawio source (app.min.js:14898), these only suppress the post-save modified-flag clearing — they do not prevent edits from setting editor.modified=true. They were ineffective for blocking beforeunload prompts and actually prevented draw.io from clearing its modified flag after save. - canPersist / canPersistChecked state and isIndexedDBUsable() probe Their only purpose was gating the dead config above. Removing them also removes a startup delay before the iframe renders. - handleDrawioAutoSave wrapper After PR #780 stripped its body, it was a pure passthrough useCallback. Now passes handleDiagramAutoSave directly to onAutoSave. - withDB / isClosingError / resetDBPromise / onversionchange / onclose / terminated handlers in lib/session-storage.ts and lib/template-storage.ts PR #648 added these to recover from 'IDBDatabase: connection is closing' errors that PR #642's first land caused via db.close() on the shared singleton. That bug was already fixed in `c5de1a1` (re-land of #642), three minutes before PR #648 commits started. The retry handlers defend against multi-tab / version-change scenarios that cannot occur in this single-instance Electron app (requestSingleInstanceLock). template-storage.ts copied the same pattern when introduced by #773. Verified: - npx tsc --noEmit passes - Manual test in dev mode: session save/load works, template create works, diagram-only persistence works.	2026-05-21 08:28:24 +09:00
Dayuan Jiang	5406778dd6	fix(electron): override draw.io iframe beforeunload to allow window close (fixes #815 ) (#840 ) The draw.io iframe registers a window.onbeforeunload handler that returns a non-empty string whenever its internal editor.modified flag is true. After the user edits text in a shape, that flag is set and never cleared. Per Electron BrowserWindow docs, returning a non-void value from any beforeunload handler in the page tree silently cancels the window close without showing a dialog. This is what caused the X button (and Cmd+Q) to do nothing for users who had typed in a shape. Calling event.preventDefault() in will-prevent-unload tells Electron to ignore the iframe's beforeunload return value and proceed with the close. The host app already persists diagrams via autosave + visibilitychange, so the prompt was unnecessary. Verified by reproducing the bug, applying the fix, and re-testing.	2026-05-20 23:33:05 +09:00

Octopus	c60e3930a3	fix: use createDeepSeek for kimi provider to handle reasoning_content in multi-turn conversations (fixes #824 ) (#825 ) Kimi thinking models (e.g. kimi-k2.6) return reasoning_content in their responses. The previous createOpenAI-based implementation silently ignored this field, so reasoning was never captured or replayed in subsequent turns. Switching to createDeepSeek (which natively understands reasoning_content) ensures that reasoning context is preserved across conversation turns, resolving the "cannot interact a second time" error with Kimi k2.6. This mirrors the existing doubao provider pattern, which already uses createDeepSeek for kimi-based models routed through Doubao.

Octopus	5c8ae4d6d7	fix: always re-fetch access code config when settings dialog opens (#816 ) When ACCESS_CODE_LIST is configured on the server, the settings dialog was not showing the access code input field in two cases: 1. Stale localStorage cache: if a user had previously visited without ACCESS_CODE_LIST enabled, the cached value of accessCodeRequired=false would be used indefinitely, hiding the password input. 2. Race condition on first visit: the dialog could open triggered by an auth error before the async fetch to /api/config completed, showing a blank settings dialog with no access code field. Fix by re-fetching /api/config whenever the dialog opens (on open change) instead of only once on mount with a cache guard. The cached value in localStorage is still updated on success, keeping the fast initial render intact while ensuring the dialog always reflects the server configuration.
