Locking, unlocking shared resource handler for lita.io.

Installation

Add lita-locker to your Lita instance's Gemfile:

gem "lita-locker"

Configuration

Optional attributes

  • per_page - The number of items to show at once when listing labels or resources. Default: 10

Example

Lita.configure do |config|
  config.handlers.locker.per_page = 3

Usage

lita-locker allows you to define resources (such as a server, or Git repo), and labels (such as "production"). Labels can have multiple resources, and resources can be referenced by multiple labels. A label can only be locked if all of the resources it uses are available.

Examples

lock web                - Make something unavailable to others
unlock web              - Make something available to others
steal web               - Make yourself the owner of something locked by someone else
locker status web       - Show the current state of web

Locking, Unlocking, State

lock <label>                  - A basic reservation, with no time limit. Can have # comments afterwards.
unlock <label>                - Remove a reservation.  This can only be done by whomever made the request. Can have # comments afterwards.
steal <label>                 - Force removal of a reservation.  This can be done by anyone. Can have # comments afterwards.
locker give <label> to <user> - Transfer ownership of a lock to another user.  This can only be done by the lock's current owner. Can have # comments afterwards.

Status

locker status <label or resource>  - Show the current state of <label or resource>
locker list <username>             - Show what locks a user currently holds
locker log <label>                 - Show up to the last 10 activity log entries for <label>
locker observe <label>             - Get a notification when <label> becomes available
locker unobserve <label>           - Stop getting notifications when <label> becomes available

Queueing

lock <label>           - If <label> is already locked, adds you to a FIFO queue of pending reservations for <label>
locker dequeue <label> - Remove yourself from the queue for <label>
