sqlite: option getters run user JS mid-call, then stale state is used #65586

Description

@TrevorBurnham

Version

v27.0.0-pre (21f0f2786f0)

Platform

Darwin 25.6.0 arm64

Subsystem

sqlite

What steps will reproduce the bug?

Several DatabaseSync methods (function, aggregate, deserialize, and backup) validate the connection, then read their options
bag with Object::Get(). A user-supplied getter runs arbitrary JavaScript at
that point, so anything checked before the read can be invalidated before it's
used. For example:

const{ DatabaseSync }=require('node:sqlite');constdb=newDatabaseSync(':memory:');db.function('f',{getuseBigIntArguments(){db.close();returnfalse;}},()=>1);

How often does it reproduce? Is there a required condition?

It reproduces consistently.

What is the expected behavior? Why is that the expected behavior?

A TypeError or ERR_INVALID_STATE, not a crash.

CreateSession() already gets this right: it parses the entire options bag
first, and only then unwraps the database, checks IsOpen(), and checks the
authorizer.

What do you see instead?

SIGSEGV (exit 139)

                          What steps will reproduce the bug?

                          Several DatabaseSync methods (function, aggregate, deserialize, and backup) validate the connection, then read their options
                          bag with Object::Get(). A user-supplied getter runs arbitrary JavaScript at
                          that point, so anything checked before the read can be invalidated before it's
                          used. For example:

                          const{ DatabaseSync }=require('node:sqlite');constdb=newDatabaseSync(':memory:');db.function('f',{getuseBigIntArguments(){db.close();returnfalse;}},()=>1);

                          How often does it reproduce? Is there a required condition?

                          It reproduces consistently.

                          What is the expected behavior? Why is that the expected behavior?

                          A TypeError or ERR_INVALID_STATE, not a crash.

                          CreateSession() already gets this right: it parses the entire options bag
                          first, and only then unwraps the database, checks IsOpen(), and checks the
                          authorizer.

                          What do you see instead?
