Analysis REST API Contracts
- Implementation is released on http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=dora-toaster and http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=master
This page gives you information on the Toaster Analysis REST API. This is a read-only API which provides information about a build that was recorded by Toaster.
It documents the search operation endpoints, parameters, and responses. You might also be interested in the Toaster installation and running instructions.
Toaster is accessible through REST APIs, which make the backend available to any client. The data collected during the build is available via an unrestricted, anonymous, read-only API running on the local host machine.
General
The data interface is available as a search query returning a list of typed objects. The request method must be GET. The answers are always returned as JSON.
API version
The REST API is versioned as to allow further upgrades without having to maintain backward compatibility through changing the major version number. Minor version numbers are intended to signify a capability level while maintaining compatibility.
This is the API version 1.0. All API requests are grouped under URL:
GET /api/1.0/
Object types
The API can return Build, Target, Target installed packages, Layer, Layer version, Task, Task dependencies, Recipe, Recipe dependencies, Build packages, Package dependencies, Package files, Variables and Log messages. Each object is described below.
Search operation
The primary operation of the API is to retrieve a set of objects from the backend based on a search operation. The result will also contain all the data for the objects being returned, as to avoid separate connections to further bring the objects of the type queried.
The search operation can also specify the ordering of the results by key.
The search parameters are the same for all object types.
URI
All the search endpoints follow the same URI pattern
GET /api/1.0/{on}s/?{parameters}
- The on is the object name, one the endpoints described below.
- The parameters are described in the next section, and are the same for all search queries
Parameters
Name | Type | Description | Comments |
---|---|---|---|
limit | number | The number of objects to be returned | - |
offset | number | Offset into the search result index. | - |
search | string | Search string for all fields | The argument is the string to be searched in the database. The backend MUST return only records that match the string. |
filter | string | String used to specify result filter function | The general form: "<FIELD>:<VALUE>[,<FIELD>:<VALUE>]*". The backend MUST only return records that have FIELD matching to the VALUE specified. The <FIELD> names for each object type are the property names of the object. |
orderby | string | The name of the field that determines the sorting of the results. | "<FIELD>:<ORDER_DIRECTION>". The results are ordered by the <FIELD> values in the <ORDER_DIRECTION> order. <ORDER_DIRECTION> values may be "asc" or "desc". |
Response
All the responses are in JSON format. The response contains a set of fields describing the content of the data, and an array with the object data inside it.
Build
Returns information about the builds recorded by Toaster.
