Which Ruby background job framework is right for you? - 0 views

  • A background or asynchronous job (or task) is one that is processed outside of the usual request/response workflow that is part of any modern web framework
  • Asynchronous tasks on the other hand, are those that may be started from a normal web request, but require a longer time to complete than the normal request.

Keepalived for Linux - 0 views

  •  
    Keepalived is a routing software written in C. The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage loadbalanced server pool according their health. On the other hand high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for router failover. In addition, Keepalived implements a set of hooks to the VRRP finite state machine providing low-level and high-speed protocol interactions. Keepalived frameworks can be used independently or all together to provide resilient infrastructures.

Queues - Laravel - The PHP Framework For Web Artisans - 0 views

  • Laravel queues provide a unified API across a variety of different queue backends, such as Beanstalk, Amazon SQS, Redis, or even a relational database.
  • The queue configuration file is stored in config/queue.php
  • a synchronous driver that will execute jobs immediately (for local use)
  • ...56 more annotations...
  • A null queue driver is also included which discards queued jobs.
  • In your config/queue.php configuration file, there is a connections configuration option.
  • any given queue connection may have multiple "queues" which may be thought of as different stacks or piles of queued jobs.
  • each connection configuration example in the queue configuration file contains a queue attribute.
  • if you dispatch a job without explicitly defining which queue it should be dispatched to, the job will be placed on the queue that is defined in the queue attribute of the connection configuration
  • pushing jobs to multiple queues can be especially useful for applications that wish to prioritize or segment how jobs are processed
  • specify which queues it should process by priority.
  • If your Redis queue connection uses a Redis Cluster, your queue names must contain a key hash tag.
  • ensure all of the Redis keys for a given queue are placed into the same hash slot
  • all of the queueable jobs for your application are stored in the app/Jobs directory.
  • Job classes are very simple, normally containing only a handle method which is called when the job is processed by the queue.
  • we were able to pass an Eloquent model directly into the queued job's constructor. Because of the SerializesModels trait that the job is using, Eloquent models will be gracefully serialized and unserialized when the job is processing.
  • When the job is actually handled, the queue system will automatically re-retrieve the full model instance from the database.
  • The handle method is called when the job is processed by the queue
  • The arguments passed to the dispatch method will be given to the job's constructor
  • delay the execution of a queued job, you may use the delay method when dispatching a job.
  • dispatch a job immediately (synchronously), you may use the dispatchNow method.
  • When using this method, the job will not be queued and will be run immediately within the current process
  • specify a list of queued jobs that should be run in sequence.
  • Deleting jobs using the $this->delete() method will not prevent chained jobs from being processed. The chain will only stop executing if a job in the chain fails.
  • this does not push jobs to different queue "connections" as defined by your queue configuration file, but only to specific queues within a single connection.
  • To specify the queue, use the onQueue method when dispatching the job
  • To specify the connection, use the onConnection method when dispatching the job
  • defining the maximum number of attempts on the job class itself.
  • to defining how many times a job may be attempted before it fails, you may define a time at which the job should timeout.
  • using the funnel method, you may limit jobs of a given type to only be processed by one worker at a time
  • using the throttle method, you may throttle a given type of job to only run 10 times every 60 seconds.
  • If an exception is thrown while the job is being processed, the job will automatically be released back onto the queue so it may be attempted again.
  • dispatch a Closure. This is great for quick, simple tasks that need to be executed outside of the current request cycle
  • When dispatching Closures to the queue, the Closure's code contents is cryptographically signed so it can not be modified in transit.
  • Laravel includes a queue worker that will process new jobs as they are pushed onto the queue.
  • once the queue:work command has started, it will continue to run until it is manually stopped or you close your terminal
  • queue workers are long-lived processes and store the booted application state in memory.
  • they will not notice changes in your code base after they have been started.
  • during your deployment process, be sure to restart your queue workers.
  • customize your queue worker even further by only processing particular queues for a given connection
  • The --once option may be used to instruct the worker to only process a single job from the queue
  • The --stop-when-empty option may be used to instruct the worker to process all jobs and then exit gracefully.
  • Daemon queue workers do not "reboot" the framework before processing each job.
  • you should free any heavy resources after each job completes.
  • Since queue workers are long-lived processes, they will not pick up changes to your code without being restarted.
  • restart the workers during your deployment process.
  • php artisan queue:restart
  • The queue uses the cache to store restart signals
  • the queue workers will die when the queue:restart command is executed, you should be running a process manager such as Supervisor to automatically restart the queue workers.
  • each queue connection defines a retry_after option. This option specifies how many seconds the queue connection should wait before retrying a job that is being processed.
  • The --timeout option specifies how long the Laravel queue master process will wait before killing off a child queue worker that is processing a job.
  • When jobs are available on the queue, the worker will keep processing jobs with no delay in between them.
  • While sleeping, the worker will not process any new jobs - the jobs will be processed after the worker wakes up again
  • the numprocs directive will instruct Supervisor to run 8 queue:work processes and monitor all of them, automatically restarting them if they fail.
  • Laravel includes a convenient way to specify the maximum number of times a job should be attempted.
  • define a failed method directly on your job class, allowing you to perform job specific clean-up when a failure occurs.
  • a great opportunity to notify your team via email or Slack.
  • php artisan queue:retry all
  • php artisan queue:flush
  • When injecting an Eloquent model into a job, it is automatically serialized before being placed on the queue and restored when the job is processed

ruby-grape/grape: An opinionated framework for creating REST-like APIs in Ruby. - 0 views

shared by 張 旭 on 17 Dec 16 - No Cached
  • Grape is a REST-like API framework for Ruby.
  • designed to run on Rack or complement existing web application frameworks such as Rails and Sinatra by providing a simple DSL to easily develop RESTful APIs
  • Grape APIs are Rack applications that are created by subclassing Grape::API
  • ...54 more annotations...
  • Rails expects a subdirectory that matches the name of the Ruby module and a file name that matches the name of the class
  • mount multiple API implementations inside another one
  • mount on a path, which is similar to using prefix inside the mounted API itself.
  • four strategies in which clients can reach your API's endpoints: :path, :header, :accept_version_header and :param
  • clients should pass the desired version as a request parameter, either in the URL query string or in the request body.
  • clients should pass the desired version in the HTTP Accept head
  • clients should pass the desired version in the UR
  • clients should pass the desired version in the HTTP Accept-Version header.
  • add a description to API methods and namespaces
  • Request parameters are available through the params hash object
  • Parameters are automatically populated from the request body on POST and PUT
  • route string parameters will have precedence.
  • Grape allows you to access only the parameters that have been declared by your params block
  • By default declared(params) includes parameters that have nil values
  • all valid types
  • type: File
  • JSON objects and arrays of objects are accepted equally
  • any class can be used as a type so long as an explicit coercion method is supplied
  • As a special case, variant-member-type collections may also be declared, by passing a Set or Array with more than one member to type
  • Parameters can be nested using group or by calling requires or optional with a block
  • relevant if another parameter is given
  • Parameters options can be grouped
  • allow_blank can be combined with both requires and optional
  • Parameters can be restricted to a specific set of values
  • Parameters can be restricted to match a specific regular expression
  • Never define mutually exclusive sets with any required params
  • Namespaces allow parameter definitions and apply to every method within the namespace
  • define a route parameter as a namespace using route_param
  • create custom validation that use request to validate the attribute
  • rescue a Grape::Exceptions::ValidationErrors and respond with a custom response or turn the response into well-formatted JSON for a JSON API that separates individual parameters and the corresponding error messages
  • custom validation messages
  • Request headers are available through the headers helper or from env in their original form
  • define requirements for your named route parameters using regular expressions on namespace or endpoint
  • route will match only if all requirements are met
  • mix in a module
  • define reusable params
  • using cookies method
  • a 201 for POST-Requests
  • 204 for DELETE-Requests
  • 200 status code for all other Requests
  • use status to query and set the actual HTTP Status Code
  • raising errors with error!
  • It is very crucial to define this endpoint at the very end of your API, as it literally accepts every request.
  • rescue_from will rescue the exceptions listed and all their subclasses.
  • Grape::API provides a logger method which by default will return an instance of the Logger class from Ruby's standard library.
  • Grape supports a range of ways to present your data
  • Grape has built-in Basic and Digest authentication (the given block is executed in the context of the current Endpoint).
  • Authentication applies to the current namespace and any children, but not parents.
  • Blocks can be executed before or after every API call, using before, after, before_validation and after_validation
  • Before and after callbacks execute in the following order
  • Grape by default anchors all request paths, which means that the request URL should match from start to end to match
  • The namespace method has a number of aliases, including: group, resource, resources, and segment. Use whichever reads the best for your API.
  • test a Grape API with RSpec by making HTTP requests and examining the response
  • POST JSON data and specify the correct content-type.
