Gets a field from the project.
This method directly queries the project hosting API using bugdroids1's,
api key.
@param field: A selector, which corresponds loosely to a field in the
new bug description of the crosbug frontend.
@raises: ProjectHostingApiException, if the request execution fails.
@return: A json formatted python dict of the specified field's options,
or None if we can't find the api library. This dictionary
represents the javascript literal used by the front end tracker
and can hold multiple filds.
The returned dictionary follows a template, but it's structure
is only loosely defined as it needs to match whatever the front
end describes via javascript.
For a new issue interface which looks like:
field 1: text box
drop down: predefined value 1 = description
predefined value 2 = description
field 2: text box
similar structure as field 1
you will get a dictionary like:
'field name 1': {
'project realted config': 'config value'
'property': [
{predefined value for property 1, description},
{predefined value for property 2, description}
'field name 2': {

Retrieve all updates for a given issue including comments, changes to
it's labels, status etc. The first element in the dictionary returned
by this method, is by default, the 0th update on the bug; which is the
entry that created it. All the text in a given update is keyed as
'content', and updates that contain no text, eg: a change to the status
of a bug, will contain the emtpy string instead.
@param issue_id: The id of the issue we want detailed information on.
@raises: ProjectHostingApiException, if the request execution fails.
@return: A json formatted python dict that has an entry for each update
performed on this issue.

List issues containing the search marker. This method will only list
the summary, title and id of an issue, though it searches through the
comments. Eg: if we're searching for the marker '123', issues that
contain a comment of '123' will appear in the output, but the string
'123' itself may not, because the output only contains issue summaries.
@param kwargs:
q: The anchor string used in the search.
can: a string representing the search space that is passed to the
google api, can be 'all', 'new', 'open', 'owned', 'reported',
'starred', or 'to-verify', defaults to 'all'.
label: A string representing a single label to match.
@return: A json formatted python dict of all matching issues.

Searches a dictionary as returned by _get_field for property lists,
then returns each value in the list. Effectively this gives us
all the accepted values for a property. For example, in crosbug,
'properties' map to things like Status, Labels, Owner etc, each of these
will have a list within the issuesConfig dict.
@param prop_dict: dictionary which contains a list of properties.
@yield: each value in a property list. This can be a dict or any other
type of datastructure, the caller is responsible for handling
it correctly.

def _get_cros_labels(self, prop_dict):
Helper function to isolate labels from the labels dictionary. This
dictionary is of the form:
"label": "Cr-OS-foo",
"description": "description"
And maps to the frontend like so:
Labels: Cr-???
Cr-OS-foo = description
where Cr-OS-foo is a conveniently predefined value for Label Cr-OS-???.
@param prop_dict: a dictionary we expect the Cros label to be in.
@return: A lower case product area, eg: video, factory, ui.
label = prop_dict.get('label')
if label and 'Cr-OS-' in label:
return label.split('Cr-OS-')[1]

Parse issue options and return a list of 'Cr-OS' labels.
@return: a list of Cr-OS labels from crosbug, eg: ['kernel', 'systems']

def create_issue(self, request_body):
Convert the request body into an issue on the frontend tracker.
@param request_body: A python dictionary with key-value pairs
that represent the fields of the issue.
eg: {
'title': 'bug title',
'description': 'bug description',
'labels': ['Type-Bug'],
'owner': {'name': 'owner@'},
'cc': [{'name': 'cc1'}, {'name': 'cc2'}]
Note the title and descriptions fields of a
new bug are not optional, all other fields are.

issue created, or an error response code and information
about a failure.

that represent the fields of the update.
'content': 'comment to add',
'labels': ['Type-Bug', 'another label'],
'owner': 'owner@',
'cc': ['cc1@', cc2@'],
Note the owner and cc fields need to be email
addresses the tracker recognizes.

@raises: ProjectHostingApiException, if request execution fails.

update of said issue, or an error response code and information
about a failure.

def _populate_issue_updates(self, t_issue):
Populates a tracker issue with updates.
Any issue is useless without it's updates, since the updates will
contain both the summary and the comments. We need at least one of
those to successfully dedupe. The Api doesn't allow us to grab all this
information in one shot because viewing the comments on an issue
requires more authority than just viewing it's title.
@param t_issue: The basic tracker issue, to populate with updates.
@raises: ProjectHostingApiException, if request execution fails.
@returns: A tracker issue, with it's updates.

include_dupes=False, label=None):
Find all Tracker issues that contain the specified search text.
@param search_text: Anchor text to use in the search.
@param full_text: True if we would like an extensive search through
issue comments. If False the search will be restricted
to just summaries and titles.
@param include_dupes: If True, search over both open issues as well as
closed issues whose status is 'Duplicate'. If False,
only search over open issues.

when we're either unable to list issues or none match the text.
