* Summary

This is a technology preview for Toaster, a web interface allowing
recording and inspecting the build process and artifacts from a
Yocto project build. The code should be treated as being an "alpha" release.

The system runs Bitbake in server-mode, a feature that was merged
in the 1.5 Dora release. The server mode accepting "observing" clients
that can listen for Bitbake events has also been developed for 1.5

A new Bitbake UI module has been developed, named "toasterui";
this UI listens for build events, retrieves information from the events,
and records the information in the database.

A web interface developed in Python/Django exposes the recorded information
in a basic HTML interface, named Simple UI; and also exposes the information
via a REST API for third party use.

The scope of the Simple UI is to allow visual data testing to verify the
quality of the backend. The Simple UI isn't an example of the final UI, nor
does it show the analysis capabilities projected for Toaster.

The final UI is still in development.

* API documentation and availability

The Toaster web interface exposes a set of REST APIs allowing third party
to retrieve and process recorded data in 3rd party applications.

The documentation for the REST API is maintained on wiki:

* Requirements

This release adds a dependency on Django version 1.4.5

* QA and Known issues.

Toaster uses partially automated testing to measure the completness
and quality of data recorded. For this release, the data completness table
is listed below, listing missing information.

No medium+ or critical bugs for this release.

Known issue with data collected for build_package,
build_package_dependency and build_file tables, this is tracked via

Our tests are run on a clean build, and therefore do not pick up this
problem. For unclean build or a failed build, the data collection and
accuracy may downgrade.

There are bugs related to completness or quality of data, which are being
tracked in Look for Product: Web - Hob,
Component: web-hob. Web-Hob and variants is the former codename for Toaster.

* Operation
