* perf(editor): stop reclassifying the whole markdown document on every render
EditorPanel re-renders from ~18 store subscriptions, and the rich-mode
classifier ran unmemoized in its render body — so an idle git-status poll
rescanned (and TipTap round-tripped) every open markdown tab.
- Memoize `getMarkdownRichModeEligibility` on (content, sizeOverridden).
Idle 60 s with one markdown tab: 31 -> 1 classifier calls, 31 -> 1
round-trip calls. Render-model self time for a 100 KB .md with HTML:
6.485 ms -> 0.004 ms per render.
- Drop the React effect that mirrored `content` into the doc-link decoration
refresh; the controller's own `onDidChangeModelContent` listener already
covers it (and catches programmatic edits). 800 -> 400 debounce timer ops
per 200 keystrokes, same decorations.
- Scan doc-link decorations by line offsets instead of per-line substrings,
reusing the allocation-free `forEachLine` from the conflict decorations.
600 KB / 46k lines: 50,853 -> 4,623 string allocations per scan,
34.1 ms -> 20.3 ms per scan.
- Replace the per-keystroke double `trimEnd()` dirty check with a
trimmed-length probe plus one native prefix compare: 400 -> 0
full-document copies (40 MB -> 0 bytes) per 200 keystrokes. Move
fileContents/diffContents behind refs so the change callback identity
stops churning on every content load.
No behavior change: rich-vs-source selection, decorations, and the dirty
dot are all covered by equivalence tests against the previous code.
* fix(editor): move the dirty-check content refs out of the render body
React Doctor's `no-ref-current-in-render` flagged the `fileContents` /
`diffContents` ref writes added for the stabilized change callback, and it
was right on substance: a render React discards would still have moved the
dirty-check baseline, so a later keystroke could be compared against content
from a render that never committed.
Assign both refs in a `useLayoutEffect` instead — the same latest-value
pattern `useIpynbDocumentEditing` already uses. Layout effects only run for
committed renders and land before any input event can reach the handler, so
the baseline is always the committed one.
The handler and its refs move into `use-editor-content-change-handler.ts`;
that keeps `EditorPanel.tsx` under the 400-line cap (no `max-lines` bump) and
puts the draft write, the dirty comparison and their inputs in one place.
Callback identity stays stable (1 distinct identity across 30 idle renders)
and every measured number is unchanged: 1 classifier call and 1 round-trip
call per 60 s idle, ~0.005 ms render-model self time for a 100 KB .md with
HTML. Also asserts the reverse direction of the reload case — the stable
handler marks the file dirty when handed the pre-reload content.
* fix(editor): keep the rich-mode fallback banner localized behind the memo
The memo keyed on `(content, sizeOverridden)`, but the value it cached was
not a pure function of those two: `unsupportedMessage` comes from a matcher
`get message()` accessor that calls `translate()` at access time, so the
active UI language is a third, ambient input. Caching the resolved string
froze the banner in whichever language was active at first classification —
visible when switching Settings → UI language, and at startup for non-English
users because `I18nProvider` applies the persisted language from an effect,
after the settings-driven render has already classified.
Adding the language to the cache key would only work until the next ambient
input. Instead, split the classifier: `getMarkdownRichModeEligibilityDecision`
returns the genuinely pure part (`exceedsSizeLimit` plus which matcher fired)
and is what the cache stores, while `resolveMarkdownRichModeUnsupportedMessage`
reads the matcher's getter per read. `getMarkdownRichModeEligibility` keeps its
old signature as a thin composition of the two.
Cost of re-resolving per read is one `i18n.t` on documents that show a banner
and nothing at all on documents that do not (a null reason short-circuits).
Render-model self time for a 100 KB .md with HTML moves 0.005 ms -> 0.011 ms,
against a 6.485 ms pre-PR baseline; classification still runs once per content
change (1 decision and 1 round-trip across 30 idle git-status ticks).
Two regression tests, both confirmed to fail against a string-caching cache:
a unit test asserting a cache hit follows `changeLanguage('ja')`, and an
EditorPanel test that renders the banner from a reference-link document,
switches the language, forces an idle store write, and asserts the Japanese
text while the decision stays cached.
