Note that all files were moved to a new directory. The diffs won't be 100% friendly because of this. Extracted common handling for OAuth on both sides of the connection in order to add a new build status data handler. This data handler will be used to report build status data. Don't look too closely at the details of what data is transferred as this will change in the next patch. We will also extract data from a different page in a slightly different way, but there won't be huge differences. In particular, we won't look at the /one_box_per_builder page on the master but rather at the transposed grid (/tgrid) on the build master since we also need the revision number. The regular expressions to extract the data will be slightly more complex.

"""This script request an access token from the appengine running the dashboard.
|
|
|
|
The script is intended to be run manually whenever we wish to change which
|
|
dashboard administrator we act on behalf of when running the
|
|
track_coverage.py script. For example, this will be useful if the current
|
|
dashboard administrator leaves the project.
|
|
|
|
This script should be run on the build bot which runs the track_coverage.py
|
|
script. This script will present a link during its execution, which the new
|
|
administrator should follow and then click approve on the web page that
|
|
appears. The new administrator should have admin rights on the coverage
|
|
dashboard, otherwise track_coverage.py will not work.
|
|
|
|
If successful, this script will write the access token to a file access.token
|
|
in the current directory, which later can be read by track_coverage.py.
|
|
The token is stored in string form (as reported by the web server) using the
|
|
shelve module.
