From a3bbcb9b39b6ff8844485140d7d890c43109990f Mon Sep 17 00:00:00 2001 From: Mahmoud Mabrouk Date: Sat, 11 Jul 2026 17:12:22 +0200 Subject: [PATCH 1/5] feat(runner): warm daytona sessions slice 1 - provider pause/reconnect, pointer guard, typed teardown Slice 1 of the warm-daytona-sessions plan (PR #5214): the correctness base, with parking still inert (every teardown reason still deletes). - daytona provider wrapper adds pause/reconnect with a bounded state machine over Daytona transitional states; deleteSandbox helper; create-spec fingerprint (snapshot/image/target/env NAMES/network policy). - sandbox-agent package patch: a failed pause keeps the provider handles so the delete fallback works; a reconnected sandbox that fails later attach steps is paused, not leaked. - sessions API: nullable session_states.sandbox_fingerprint column; the sandbox pointer write is guarded by a compare-and-set on data.latest_turn_index (sandbox_turn_index token; tokenless writes keep today's behavior). - runner: pointer write is awaited, carries the fingerprint and guard token, and moved after continuity hydrate so a cold restart sends the right token; reconnect only on fingerprint match, best-effort delete on mismatch. - typed teardown reasons replace the keepWarm boolean; reason-to-disposition mapping with PARK_CLEAN_RESUMABLE_TURNS=false (Slice 2 flips it).

Requires alembic migration core_oss oss000000011 (nullable session_states.sandbox_fingerprint). Carries shared-file hunks from the unmerged lanes feat/keepalive-project-scope (protocol.ts runContext scope and pool key preference) and fix/sessions-continuity-review (models.py replica_id validation, mdx edits) per the coordination board's shared-file rule.

A second turn inside the window continues the + live session. Measured on the dev stack: 1.4 s against 12.5 s cold. +- **Park-to-stopped.** When the window expires (or the warm cap is full, or the runner drains + on SIGTERM while idle), the sandbox is stopped, not deleted. The next turn restarts the + same instance and reloads the harness session natively. Measured: 7.7 s against 12.5 s + cold, because `session/load` (1.2 s) replaces the 5.2 s session create. +- **A hard cap on idle warm sandboxes** (`AGENTA_RUNNER_DAYTONA_SESSION_MAX_WARM`, default + 20). It bounds idle spend only; an active turn is never blocked. On overflow a finishing + turn parks to stopped. The Daytona pool frees a warm slot only after a stop is confirmed, + so an in-flight stop cannot let the billed count overshoot. + +The correctness base underneath: + +- The vendored Daytona provider gets real `pause` and `reconnect` functions (a runner-side + wrapper over `sandbox-agent`): stop only from a running state, wait out Daytona's + transitional states with a bound, resume stopped or archived instances, and fail cleanly on + error states. Two teardown bugs in the vendored package are fixed in the package patch: a + failed pause used to clear the provider handle so the delete fallback silently did nothing + (a leaked billed sandbox), and a reconnected sandbox that failed later attach steps leaked. +- The sandbox pointer (`session_states.sandbox_id`) is now written awaited and guarded: the + API applies it only when the writer's turn index is not older than the row's + `latest_turn_index` (a compare-and-set; tokenless writes keep today's behavior). A stored + pointer also carries a fingerprint of the create-time settings (snapshot, image, target, + env names, network policy); reuse happens only on an exact match, otherwise the old + sandbox is deleted and the turn builds fresh. +- Teardown takes a typed reason instead of a `keepWarm` boolean. Kill, failed, aborted, and + mismatch delete; a clean resumable turn and idle shutdown stop; in-flight shutdown deletes. + The keepalive pool passes its eviction reason through the same mapping. +- Auto-archive is removed entirely (create field, env override, compose and helm forwarding): + restoring from archive measured slower than creating fresh. The ladder is stop after 15 + idle minutes (was 5), delete after 30. +- One `SessionPool` per provider. Local behavior and env vars are unchanged; the local pool + keeps its fire-and-forget eviction, the Daytona pool gets strict awaited capacity. +- Acquire now logs per-stage `[timing]` lines (create, install, mounts, workspace, probe, + session), so the next latency investigation reads the logs instead of hand-instrumenting. + +## Migration required + +One alembic migration (core_oss `oss000000011`) adds the nullable +`session_states.sandbox_fingerprint` column. Deployments that update the code without running +the migration will break sessions continuity silently: every `session_states` read and write +errors on the missing column and `intercept_exceptions` masks it as an empty result. Run the +core_oss chain when deploying this. + +## Assumptions from the two open plan questions + +- Pointer-write guard: compare-and-set on the existing `latest_turn_index` turn counter (the + plan's default wording; no schema migration for the guard itself). Two truly concurrent + turns of the same conversation carry the same index and still race; the guard closes the + older-write-lands-last window.

A resumed Daytona turn reconnects the parked instance by id. Snapshot, image, and target drift is accepted as per-conversation version pinning. Network policy is converged at reconnect: read the live networkBlockAll/networkAllowList and call updateNetworkSettings only when they differ from the run's plan. Per-turn env sync is deferred to the daytona-secret-delivery direction (#5223). Removes the session_states.sandbox_fingerprint column and migration oss000000011, the createSpecFingerprint/buildResolvedDaytonaCreate helpers, and the fingerprint fields on the pointer read/write. Keeps the turn-index compare-and-set guard on sandbox_id, which uses only pre-existing columns.
