The Malone (Launchpad) XMLRPC Interface

Malone currently provides an XML-RPC interface for filing bugs.

Synopsis

from xmlrpclib import ServerProxy

s = ServerProxy("https://test@canonical.com:test@xmlrpc.launchpad.net/bugs/")
s.filebug(dict(
    distro="ubuntu", package="mozilla-firefox",
    summary="the summary", comment="the description",
    subscribers=["foo.bar@canonical.com"]))

For the truly interested

• >>> from canonical.launchpad.xmlrpc import FileBugAPI

  >>> filebug_api = FileBugAPI(None, None)

The filebug API

The filebug API is:

    filebug_api.filebug(params)

params is a dict, with the following keys:

• REQUIRED ARGS:
  • summary: A string
  • comment: A string
  OPTIONAL ARGS:
  • product: The product name, as a string. Default None.
  • distro: The distro name, as a string. Default None.
  • package: A string, allowed only if distro is specified. Default None.
  • security_related: Is this a security vulnerability? Default False.
  • subscribers: A list of email addresses. Default None.

Either product or distro must be provided. The bug owner is the currently authenticated user, taken from the request. The return value is the bug URL, in short form, e.g.:

• http://launchpad.net/bugs/42

Examples

First, let's define a simple event listener to show that the ISQLObjectCreatedEvent is being published when a bug is reported through the XML-RPC interface.

    >>> from canonical.launchpad.event.interfaces import ISQLObjectCreatedEvent
    >>> from canonical.launchpad.ftests.event import TestEventListener
    >>> from canonical.launchpad.interfaces import IBug

    >>> def on_created_event(obj, event):
    ...     print "SQLObjectCreatedEvent: %r" % obj

    >>> on_created_listener = TestEventListener(
    ...     IBug, ISQLObjectCreatedEvent, on_created_event)

Reporting a product bug

(We'll define a simple function to extract the bug ID from the URL return value.)

    >>> def get_bug_id_from_url(url):
    ...     return int(url.split("/")[-1])

    >>> login("test@canonical.com")

    >>> params = dict(
    ...     product='firefox', summary='the summary', comment='the comment')
    >>> bug_url = filebug_api.filebug(params)
    SQLObjectCreatedEvent: <Bug ...>
    >>> print bug_url
    http://launchpad.dev/bugs/...

    >>> from zope.component import getUtility
    >>> from canonical.launchpad.interfaces import IBugSet

    >>> bugset = getUtility(IBugSet)
    >>> bug = bugset.get(get_bug_id_from_url(bug_url))

    >>> print bug.title
    the summary
    >>> print bug.description
    the comment
    >>> print bug.owner.name
    name12

    >>> firefox_bug = bug.bugtasks[0]

    >>> print firefox_bug.product.name
    firefox

Reporting a distro bug

    >>> params = dict(
    ...     distro='ubuntu', summary='another bug', comment='another comment')
    >>> bug_url = filebug_api.filebug(params)
    SQLObjectCreatedEvent: <Bug ...>
    >>> print bug_url
    http://launchpad.dev/bugs/...

    >>> bug = bugset.get(get_bug_id_from_url(bug_url))

    >>> print bug.title
    another bug
    >>> print bug.description
    another comment
    >>> print bug.owner.name
    name12

    >>> ubuntu_bug = bug.bugtasks[0]

    >>> print ubuntu_bug.distribution.name
    ubuntu
    >>> ubuntu_bug.sourcepackagename is None
    True

Reporting a package bug

    >>> params = dict(
    ...     distro='ubuntu', package='evolution', summary='email is cool',
    ...     comment='email is nice', security_related=True,
    ...     subscribers=["no-priv@canonical.com"])
    >>> bug_url = filebug_api.filebug(params)
    SQLObjectCreatedEvent: <Bug ...>
    >>> print bug_url
    http://launchpad.dev/bugs/...

    >>> bug = bugset.get(get_bug_id_from_url(bug_url))

    >>> print bug.title
    email is cool
    >>> print bug.description
    email is nice
    >>> bug.security_related
    True
    >>> bug.private
    True
    >>> sorted(p.name for p in bug.getDirectSubscribers())
    [u'name12', u'no-priv', u'ubuntu-team']
    >>> bug.getIndirectSubscribers()
    []

    >>> evolution_bug = bug.bugtasks[0]

    >>> print evolution_bug.distribution.name
    ubuntu
    >>> print evolution_bug.sourcepackagename.name
    evolution

Error Handling

Malone's xmlrpc interface provides extensive error handling. The various error conditions it recognizes are:

Failing to specify a product or distribution.

    >>> params = dict()
    >>> filebug_api.filebug(params)
    <Fault 60: 'Required arguments missing. You must specify either a product or distrubtion in which the bug exists.'>

Specifying *both* a product and distribution.

    >>> params = dict(product='firefox', distro='ubuntu')
    >>> filebug_api.filebug(params)
    <Fault 70: 'Too many arguments. You may specify either a product or a distribution, but not both.'>

Specifying a non-existent product.

    >>> params = dict(product='nosuchproduct')
    >>> filebug_api.filebug(params)
    <Fault 10: 'No such product: nosuchproduct'>

Specifying a non-existent distribution.

    >>> params = dict(distro='nosuchdistro')
    >>> filebug_api.filebug(params)
    <Fault 80: 'No such distribution: nosuchdistro'>

Specifying a non-existent package.

    >>> params = dict(distro='ubuntu', package='nosuchpackage')
    >>> filebug_api.filebug(params)
    <Fault 90: 'No such package: nosuchpackage'>

Missing summary.

    >>> params = dict(product='firefox')
    >>> filebug_api.filebug(params)
    <Fault 100: 'Required parameter missing: summary'>

Missing comment.

    >>> params = dict(product='firefox', summary='the summary')
    >>> filebug_api.filebug(params)
    <Fault 100: 'Required parameter missing: comment'>

Invalid subscriber.

    >>> params = dict(
    ...     product='firefox', summary='summary', comment='comment',
    ...     subscribers=["foo.bar@canonical.com", "nosuch@subscriber.com"])
    >>> filebug_api.filebug(params)
    <Fault 20: 'Invalid subscriber: No user with the email address
    "nosuch@subscriber.com" was found'>

    >>> on_created_listener.unregister()
