RxDBSystemMigrationLockError

Defined in: packages/rxdb/src/system/migration.ts:189

拿不到系统迁移所需的排他锁，本次迁移整体未执行

Remarks​

由适配器抛出，触发条件是「此刻改 schema 不安全」而不是「改失败了」：PGlite 走 LOCK TABLE ... NOWAIT 拿不到锁、或 hasStoragePeer() 报告另一个客户端正持有同一份持久化存储； sqlite 系走各自绑定的等价判据。两种情况下 DDL 一行都没落地——检查在事务里、抢先返回， 所以收到它时库还停在迁移前的完整状态，不需要任何回滚补偿。

不做自动重试是有意的：持有方通常是用户的另一个标签页或另一个进程，重试只会在锁上空转。 调用方应把它当作「请关掉另一个打开该库的窗口后重开」报给用户。

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

Methods​

captureStackTrace()​

static captureStackTrace(targetObject, constructorOpt?): void;

Defined in: node_modules/.pnpm/@types+node@26.6.3/node_modules/@types/node/globals.d.ts:51

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}
