node:sqlite on native payloads; cheaper native callback path; statements own their sqlite3_stmt - #12109

…ls JS through the owner edge (Refs #11919) DatabaseSync, StatementSync, StatementSyncIterator, SQLTagStore, Session and db.limits are ordinary objects with a family class id and prototype; the database payload owns the sqlite3 connection. UDFs, aggregates and the authorizer are registered in the owner's callbacks array and reached from C through CallbackSite userdata and the cell's traced owner edge; aggregate accumulators live in the owner's JS state. Every callback-capable C call runs between native_payload::enter and finish with no payload borrow or lock held: a throw inside SQLite is parked and rethrown after the call, the first throw wins, nested calls re-enter freely, and close() inside a callback is deferred to the end of the outer call, which reports the closed database. applyChangeset filter/onConflict use per-call stack userdata. Statements own no C statement (they compile per run) and carry the open's OpenSerial; close()/open() keep the same object. Deleted: NODE_SQLITE_CUSTOM_FUNCTIONS / _AGGREGATES / _ACTIVE_AGGREGATES, their root scanner and thread-exit hooks, the node handle producers and dispatch-hub arms, the node:sqlite native-table receiver rows, the legacy runtime StatementSync/Session constructor values and forwarding prototypes, and the sqlite-only array-iterator kind. bun:sqlite and Bun.SQL keep their registry handles. Runtime: JS state fields past the inline slots use overflow storage; %IteratorPrototype% has Symbol.toStringTag "Iterator"; native_payload gains state_get/state_set, define_own_accessor, symbol_method, prototype(), iterator_prototype() and iter_result_done_value().
…back; payload instances born in their final shape; node:sqlite statements own their compiled statement (Refs #11919) Callback path: the native call's reused catch refreshes only the runtime handle depth, a compiler-emitted callback body is entered directly, and call_callback checks the owner once (open, this thread, nothing pending) before the inlined slot read. call_from_link keeps its per-call state check without re-proving the thread the trampoline proved. Payload method dispatch drops two redundant descriptor scans. Birth: alloc_with_state takes the site's own accessors and a BirthMemo; the first birth records the instance and JS-state ShapeIds, later births allocate in them (validated per use) and hold the family's shared accessor pairs from the prototype's JS state. SQLite: a statement compiles once at prepare() and owns the statement, as node does, so the authorizer runs once per prepare() instead of once more per run; expandedSQL and columns() read the compiled statement.
…e builds it node 26's SQLite reports DEFAULT_MEMSTATUS=0 in PRAGMA compile_options; perry's bundled build kept the default (1), so every sqlite3_malloc took the global memory-statistics mutex and updated its counters. Nothing in perry reads SQLite's memory statistics.
…coincide (Refs #11919) test_gap_11919_sqlite_statement_owned compares with node: the authorizer runs at prepare() only, expandedSQL reads the last bindings, columns() and iterate() run nothing extra, own getters are born on every statement, an own property shadows a prototype method, a nested statement runs from a UDF, and statements left over after close() are finalized once. native_call_reuses_catch_refreshes_roots_and_pops roots two values in its second trampoline: the first callback's capture sits one root above the guard, so a single root hid a missing refresh (catch_refresh stayed GREEN).

Merge Risk: 🟠 High · up to A failed database deserialize can corrupt memory, for example while a transaction is active. Separately, an authorizer callback that runs during serialize, deserialize or session changeset generation can close the database while SQLite is still using it. Both problems can crash the process and should be fixed before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Review comments at @crates/perry-stdlib/src/sqlite/database_sync.rs:
- Around line 889-916: Guard the authorizer-triggering SQLite calls in
db_serialize_thunk and db_deserialize_thunk, and in session.rs at lines 143–148
for changeset/patchset generation. Route SQLite errors through throw_call_end
before throwing, allocate serialized Buffers only after the guard, and ensure
SQLite-owned buffers are freed on every return path. Defer SessionCell deletion
until make_blob returns so Session.close() cannot invalidate an in-flight
operation. Also guard sqlite3_load_extension when its selected initializer
executes SQL.
Review comments at @crates/perry-stdlib/src/sqlite/node_db.rs:
- Around line 266-268: Remove the manual allocation free from the
SQLITE_DESERIALIZE_FREEONCLOSE failure branch in sqlite_deserialize_main; SQLite
already frees the buffer when sqlite3_deserialize fails. Keep the existing
throw_sqlite_error_from_db error handling.

Guard SQLite calls that can invoke the authorizer.
When a JS authorizer is installed, sqlite3_serialize can prepare internal PRAGMA SQL, sqlite3_deserialize prepares an ATTACH, and session changeset/patchset generation prepares a SELECT. These calls run outside guarded. On a direct call, busy remains zero. If the authorizer calls db.close(), the connection can be released while SQLite is still using it. A thrown callback can also remain in pendingException until a later guarded call. If a guarded callback re-enters one of these APIs, the nested callback can reuse the outer NativeCatch slot, leave it NativeInactive, and cause a later JS throw to abort.
Guard these calls, return SQLite errors as data, and throw only after throw_call_end; allocate the serialized Buffer after the guard. sqlite3_load_extension invokes the selected extension initializer, so guard it when that initializer executes SQL. For changeset/patchset, also defer SessionCell deletion until make_blob returns: guarding the database alone does not defer Session.close(). Keep SQLite-owned buffers freed on every return path.

Guard the authorizer-triggering SQLite calls in db_serialize_thunk and
db_deserialize_thunk, and in session.rs at lines 143–148 for changeset/patchset
generation. Route SQLite errors through throw_call_end before throwing, allocate
serialized Buffers only after the guard, and ensure SQLite-owned buffers are
freed on every return path. Defer SessionCell deletion until make_blob returns
so Session.close() cannot invalidate an in-flight operation. Also guard
sqlite3_load_extension when its selected initializer executes SQL.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Remove the manual sqlite3_free call. It causes a double free when sqlite3_deserialize fails.
The call passes SQLITE_DESERIALIZE_FREEONCLOSE. With that flag set, SQLite takes ownership of the buffer immediately. If sqlite3_deserialize fails for any reason, SQLite calls sqlite3_free(P) before it returns. In sqlite3_deserialize, the end_deserialize path frees pData whenever FREEONCLOSE is set. pData is set to null only on success.
On the failure branch, the helper then calls ffi::sqlite3_free(allocation.cast()) a second time. This frees the same allocation twice. The result is heap corruption in SQLite's allocator.
These are realistic triggers:
db.deserialize(image)runs while a transaction or a backup holds the connection. In this state the internalATTACHreturnsSQLITE_BUSY.- Any other error return from
sqlite3_deserialize.
sqlite_deserialize_main is now a shared pub(crate) helper. The double free can therefore affect every caller of this helper, not only bun_sqlite_database_deserialize.
🐛 Proposed fix
if rc != ffi::SQLITE_OK {
- ffi::sqlite3_free(allocation.cast());
+ // With SQLITE_DESERIALIZE_FREEONCLOSE, SQLite already freed
+ // `allocation` before returning an error.
throw_sqlite_error_from_db(db);

Remove the manual allocation free from the SQLITE_DESERIALIZE_FREEONCLOSE
failure branch in sqlite_deserialize_main; SQLite already frees the buffer when
sqlite3_deserialize fails. Keep the existing throw_sqlite_error_from_db error
handling.

Merged with main e87628e (B2c #12108). B2c's scoped byte access is carried into the rewritten SQLite files: backup, bind, node_db, plus database_sync and session. The layout baseline is byte-identical to main's (282, 0 new). Re-verified: runtime and codegen tests clean, stdlib has the same 2 thread-exit failures as main, the SQLite gap tests are as before (two fixed vs main), all 7 programs match node, and instructions are within ±0.07%. |

PerryTS#12109 (node:sqlite on native payloads) failed six checks on main. - File size: native_payload.rs's hidden JS-state group moves to the native_payload_state.rs child. The public paths are re-exported. - Address classes: install_own_builtin_accessor guards with is_handle_band. The guard also rejects 0x10000..0x100000, where no heap object lives. - Raw-handle debt: the native-payload tests and native_payload_birth pass handles through with_mut_ptr and with_const_ptr. - Native-handle ledger: PerryTS#12109 removed three sqlite handle tables, so the census fell below the fixed floor of 200. The floor now follows the ledger: the census may not drop below 90% of the recorded totals or below 150. The self-test plants a collapse and a 20% drop. - GC holders: four holders lost their accidental coverage with the sqlite scanner. Each gets a researched not_a_gc_pointer verdict. - Warnings: drop an unneeded unsafe block and two unused imports.

Refs #11919. node:sqlite becomes native-payload objects, and the shared native callback path gets cheaper (owner decisions 84 and 87).
Removes:
The ledgers only go down: native_handle 199/186 → 196/183, result ledger 252/228 → 236/215, unrooted-local 339 → 315.
Changes:
db.execdeadlocked.sqlite3_stmt, as in node. The authorizer runs once perprepare(), andexpandedSQLandcolumns()read the compiled statement. A sharedlivetoken finalizes each statement exactly once.SQLITE_DEFAULT_MEMSTATUS=0, matching node 26'scompile_options.Micro-benchmarks (instructions vs the pre-conversion base):
sq_auth's base compiled each statement twice and ran the authorizer twice, so its output differed from node's. The remaining cost is SQLite lookaside overflow while statements stay alive until GC, plus the full collections that finalize payload cells. That is accepted under PERF_POLICY rule 4 (decision 87), with the pacing follow-up in MEMORY_PLAN item 6.
Tests (main 899aecd merged):
Programs (output == node): tsc −0.03%, fastify −0.05%, Zod −0.03%; the others are within ±0.01%.
