GitHub Removes Malicious Pull Requests Targeting Open Source Repositories
GitHub removed 27 malicious pull requests attempting to inject harmful code across multiple open source repositories, in another round of low-effort attacks.
@aws-sdk/util-waiter
Advanced tools
@aws-sdk/util-waiter is a utility package in the AWS SDK for JavaScript that provides functionality to wait for a resource to reach a desired state. This is particularly useful for operations that are asynchronous and may take some time to complete, such as creating or deleting AWS resources.
Wait for a resource to reach a desired state
This feature allows you to wait until a DynamoDB table exists. The `waitUntilTableExists` function polls the `DescribeTableCommand` until the table reaches the 'ACTIVE' state or the maximum wait time is reached.
const { DynamoDBClient, DescribeTableCommand } = require('@aws-sdk/client-dynamodb');
const { waitUntilTableExists } = require('@aws-sdk/util-waiter');
const client = new DynamoDBClient({ region: 'us-west-2' });
const params = { TableName: 'my-table' };
const run = async () => {
try {
const result = await waitUntilTableExists({ client, maxWaitTime: 300 }, { TableName: 'my-table' });
console.log('Table exists:', result);
} catch (error) {
console.error('Error waiting for table to exist:', error);
}
};
run();
Custom waiters
This feature allows you to create custom waiters for any AWS resource. In this example, a custom waiter is created to wait until an EC2 instance is in the 'running' state.
const { EC2Client, DescribeInstancesCommand } = require('@aws-sdk/client-ec2');
const { createWaiter, WaiterState } = require('@aws-sdk/util-waiter');
const client = new EC2Client({ region: 'us-west-2' });
const checkInstanceRunning = async () => {
const command = new DescribeInstancesCommand({ InstanceIds: ['i-1234567890abcdef0'] });
const result = await client.send(command);
const instance = result.Reservations[0].Instances[0];
return instance.State.Name === 'running' ? { state: WaiterState.SUCCESS } : { state: WaiterState.RETRY };
};
const run = async () => {
try {
const result = await createWaiter({ client, maxWaitTime: 300 }, checkInstanceRunning);
console.log('Instance is running:', result);
} catch (error) {
console.error('Error waiting for instance to run:', error);
}
};
run();
The `promise-retry` package provides a way to retry a function that returns a promise until it succeeds or a maximum number of retries is reached. Unlike @aws-sdk/util-waiter, it is not specific to AWS resources and can be used for any asynchronous operation.
The `async-retry` package is another utility for retrying asynchronous operations. It allows you to specify retry strategies and is more flexible in terms of configuration compared to @aws-sdk/util-waiter, but it does not provide built-in support for AWS resource states.
