sync: adopt upstream streaming and persistence performance work by aaditagrawal · Pull Request #267 · aaditagrawal/t3code

aaditagrawal · 2026-09-05T06:32:49Z

The previous sync stack stopped before upstream's streaming and persistence performance pass. Incorporates upstream through 6365919f2e, including bounded live queues, aggregate-scoped thread replay, scalar snapshot queries, batched projection cursors, and chunked terminal history.

Preserves fork legacy event normalization/redaction, quota activity, title-failure state, eager subscriptions, and Hermes receipts. This extends #266; the next PR completes the remaining upstream commits.

Validation: full workspace vp check and vp run typecheck; focused persistence, replay, terminal, overflow, quota, and title tests passed. Tests use the workspace-pinned Vite+ binary.

Cmd+S opened the stash menu even when the composer was empty and only one prompt was stashed. It now restores that prompt directly, so repeated presses toggle between the draft and stash. Multiple entries and images that are still saving open the menu. The stash badge still opens the menu. Validation: 94 focused stash, shortcut, and attachment tests pass. Web typecheck and formatting pass. Targeted lint has no new warnings or errors. Browser checks were skipped at Theo's request. Original implementation by Theo Browne. No code changes were needed during the takeover audit. Audited with GPT-6 Astra (preview) in Codex.

Replace stale local desktop sessions in one transaction. Preserve paired clients and browser sessions, and keep the previous credential valid if replacement fails. Closes pingdotgg#6283. Original implementation by seeb1337. Reviewed and verified with GPT-6 Astra (preview) in Codex.

…tgg#9647) Allow Antigravity threads to resume while saved Google sign-in is unchecked after a server restart. Keep confirmed authentication failures and installation errors visible. Validated with 136 focused tests, web typecheck, targeted lint, and CI. Browser verification was omitted at the maintainer's request. Created with GPT-6 Astra (preview) in Codex.

OpenCode could show an Approval badge with no controls, appear stuck on TodoWrite, and keep showing a running turn after Stop. - Show every permission, including old saved requests. Keep failed replies retryable and close completed requests even when reply events are lost. - Keep OpenCode output pipes drained and automatic replies out of the event loop. Handle disconnects, reconnects, and confirmed stops without stale requests or running states. - Show native task progress and command results. Do not treat TodoWrite or approval history as file edits or executed commands. - Ignore late aborts and task updates after a turn finishes. Fixes pingdotgg#4795 Fixes pingdotgg#7113 Fixes pingdotgg#5760 Created with GPT-6 Astra (preview) in Codex. Reviewed and merged with Claude Fable 5.1 in Claude Code.

Defer the draft walk and JSON serialization until the storage write flushes. Preserve hydration, migrations, attachment verification, and final flushes. Continues the web portion of [pingdotgg#9049](pingdotgg#9049). The mobile storage migration remains separate. Created with GPT-6 Astra (preview) in Codex.

) Append terminal history incrementally and materialize text for snapshots and coalesced disk writes. Clear evicted line references without changing retained output. Continues [pingdotgg#9357](pingdotgg#9357). The original contribution and author credit are preserved. The current line limit and wire format stay unchanged. A strict byte limit remains separate work. Created with GPT-6 Astra (preview) in Codex. Co-authored-by: will <will@moondiner.com>

Bound cached parsed review sections by eight entries and 4,194,304 full source characters. Evicted inactive parsed and native results can be collected. Raw patches, comments, and view state stay unchanged. Prewarm only nearby sections that fit beside the selected section. Use actual retained source weights for normalized cache hits, and skip oversized prewarms. Created with GPT-6 Astra (preview) in Codex.

Build one ordered terminal metadata index per immutable snapshot. Reuse unchanged session wrappers and thread groups across consumers, with separate environment targets. Keep numeric ordering, picker ties, attach state, and subscription lifetimes unchanged. Let retired snapshots and groups be collected. Created with GPT-6 Astra (preview) in Codex.

Keep at most 5,000 lines and 8 MiB of retained UTF-8 terminal history. Discard the oldest text at either limit while preserving complete live output. Track bytes and newlines in small chunks. Join split surrogates before eviction. Restore only the needed file tail, handle short reads, and close the file before rewriting current or legacy history.

Close a thread's live detail stream when its last consumer leaves. Retain a registry-local completed state and replay cursor for five idle minutes. Keep warm lookup independent of collectible raw atom definitions. Preserve paging and deletion state, reject stale owners, and cache only completed data/cursor updates. Skip repeated saves of unchanged data while retaining dirty-data flushes and failed-write retries. Verify real GC/remount behavior and focused lifecycle cases.
