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.
