fix(Poll): port the poll vote debounce removal (#3308) to v15 - #3309
Merged

Conversation
Remove the 100ms debounce around casting/removing a poll vote, and ignore auto-repeated keydown so a held key toggles the vote once. Unlike v14, stream-chat 10 does not apply own votes optimistically yet, so a second click before the server responded still reads the previous vote state. The stream-chat version is unchanged. Refs REACT-1207
📝 WalkthroughWalkthroughPoll votes are now submitted immediately. Repeated Enter or Space keydown events do not trigger additional vote toggles. Tests cover repeated keydown events and synchronous click voting. ChangesPoll voting
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: 🔵 Low · up to Rapid double clicks on a poll option may send a duplicate vote instead of removing the vote until the server confirms. This is a narrow, acknowledged edge case, so the change is mergeable with owner awareness. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Voting permissions and request targets remain unchanged. However, repeated clicks can now send multiple requests before the displayed vote state updates. Request ordering, duplicate handling and recovery guarantees are unverified; no new authorization bypass was established. Retained concerns

repeated clicks from calling poll.castVote while the first cast is still pending

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Prevent duplicate casts while a vote is pending.
If a user clicks the same option twice before the server event updates ownVotesByOptionId, both calls read the option as unselected. Both calls then invoke poll.castVote; the second click cannot remove the vote. Track a pending action for the option until vote state catches up, or otherwise prevent the second cast.

Goal
Port the stream-chat-react part of #3308 to v15: poll votes are no longer sent through a 100ms debounce, and a held key no longer toggles the vote on every auto-repeat.
Linear: REACT-1207
Implementation details
PollOptionSelector.toggleVoteis now a plainuseCallback, so a vote is sent on click without the 100ms delay. The oldlodash.debounceinstance was recreated on every vote and never cancelled.lodash.debouncestays a dependency, as other components still use it.onKeyDownreturns early onevent.repeat(afterpreventDefault(), so a held Space still does not scroll the page).10.0.0-rc.15). On v14 the change came with a bump to stream-chat 9.54.0, which applies own votes optimistically and sends vote requests in order. The same optimistic poll votes were ported to v10 in feat: poll optimistic votes v10 port stream-chat-js#1904 and released instream-chat@10.0.0-rc.19. Moving master from rc.15 to rc.19 also brings in the breaking changes of rc.16 to rc.18 (26 type errors and 62 failing tests on this branch), which feat: adopt TS generator changes #3306 is already adopting up to rc.18, so the bump is not done here.Known gap until master is on
stream-chat@10.0.0-rc.19: on rc.15 the vote state only changes when the server's event arrives, so a second click before that still reads the previous state and sends another cast instead of a removal. The debounce only merged clicks less than 100ms apart, so it covered this partially before. rc.19 fixes this (stream-chat-js #1904); once master is on it, the rapid-click test from #3308 can be ported too.Tests (
PollOptionList.test.tsx):castVote. Fails without theevent.repeatguard.UI Changes
None visually. Votes register without the 100ms delay, and a held key toggles the vote once.
