Person
======
The Person class is what we use to represent Launchpad users, teams and
some people which have done work on the free software community but are
not Launchpad users.
>>> from zope.component import getUtility
>>> from lp.services.identity.interfaces.emailaddress import (
... IEmailAddressSet)
>>> from lp.services.webapp.testing import verifyObject
>>> from lp.registry.interfaces.person import (
... IHasStanding,
... IPerson,
... IPersonSet,
... )
>>> from lp.registry.interfaces.product import IProductSet
>>> from lp.translations.interfaces.hastranslationimports import (
... IHasTranslationImports)
Any Person object (either a person or a team) implements IPerson...
>>> personset = getUtility(IPersonSet)
>>> foobar = personset.getByName('name16')
>>> foobar.is_team
False
>>> verifyObject(IPerson, foobar)
True
>>> ubuntu_team = personset.getByName('ubuntu-team')
>>> ubuntu_team.is_team
True
>>> verifyObject(IPerson, ubuntu_team)
True
...and IHasTranslationImports...
>>> IHasTranslationImports.providedBy(foobar)
True
>>> verifyObject(IHasTranslationImports, foobar)
True
>>> IHasTranslationImports.providedBy(ubuntu_team)
True
>>> verifyObject(IHasTranslationImports, ubuntu_team)
True
...and IHasStanding. Teams can technically also have standing, but it's
meaningless because teams cannot post to mailing lists.
>>> IHasStanding.providedBy(foobar)
True
>>> verifyObject(IHasStanding, foobar)
True
The IPersonSet utility
----------------------
Access to people (Persons or Teams) is done through the IPersonSet
utility:
>>> from lp.services.webapp.testing import verifyObject
>>> verifyObject(IPersonSet, personset)
True
You can create a new person using the createPersonAndEmail method of
IPersonSet. All you need for that is a valid email address. You can also
hide the user email addresses.
Some of our scripts may create Person entries, and in these cases they
must provide a rationale and a comment (optional) for the creation of
that Person entry. These are displayed on the home pages of unvalidated
Launchpad profiles, to make it clear that those profiles were not
created by the people they represent and why they had to be created.
Because the comment will be displayed verbatim in a web page, it must
start with the word "when" followed by a description of the action that
caused the entry to be created.
>>> from lp.services.identity.interfaces.emailaddress import (
... EmailAddressStatus)
>>> from lp.registry.interfaces.person import PersonCreationRationale
>>> p, email = personset.createPersonAndEmail(
... 'randomuser@randomhost.com', PersonCreationRationale.POFILEIMPORT,
... comment='when importing the Portuguese translation of firefox',
... hide_email_addresses=True)
>>> import transaction
>>> transaction.commit()
>>> p.teamowner is None
True
>>> email.status == EmailAddressStatus.NEW
True
>>> p.is_valid_person # Not valid because no preferred email address
False
>>> p.hide_email_addresses
True
Since this person has chosen to hide his email addresses they won't be
visible to other users which are not admins.
>>> from lp.services.webapp.authorization import check_permission
>>> login('randomuser@randomhost.com')
>>> check_permission('launchpad.View', email)
True
>>> login('test@canonical.com')
>>> check_permission('launchpad.View', email)
False
>>> login('guilherme.salgado@canonical.com')
>>> check_permission('launchpad.View', email)
True
>>> login(ANONYMOUS)
By default, newly created Person entries will have
AccountStatus.NOACCOUNT as their account_status. This is only changed
if/when we turn that entry into an actual user account. Note that both
the Person and the EmailAddress have accounts when they are created
using the createPersonAndEmail() method.
>>> p.account_status
<DBItem AccountStatus.NOACCOUNT...
>>> email.accountID == p.accountID
True
>>> p.setPreferredEmail(email)
>>> email.status
<DBItem EmailAddressStatus.PREFERRED...
>>> p.account_status
<DBItem AccountStatus.NOACCOUNT...
>>> from lp.services.identity.model.account import Account
>>> from lp.services.database.lpstorm import IMasterStore
>>> account = IMasterStore(Account).get(Account, p.accountID)
>>> account.activate(
... "Activated by doc test.",
... password=p.password,
... preferred_email=email)
>>> p.account_status
<DBItem AccountStatus.ACTIVE...
The user can add additional email addresses. The
validateAndEnsurePreferredEmail() method verifies that the email belongs
to the person, and it updates the email address's status.
>>> emailset = getUtility(IEmailAddressSet)
>>> validated_email = emailset.new(
... 'validated@canonical.com', p, account=p.account)
>>> validated_email.status
<DBItem EmailAddressStatus.NEW...
>>> login('randomuser@randomhost.com')
>>> p.validateAndEnsurePreferredEmail(validated_email)
>>> validated_email.status
<DBItem EmailAddressStatus.VALIDATED...
The user can add a new address and set it as the preferred address. The
setPreferredEmail() method updated the address's status.
>>> preferred_email = emailset.new(
... 'preferred@canonical.com', p, account=p.account)
>>> preferred_email.status
<DBItem EmailAddressStatus.NEW...
>>> p.setPreferredEmail(preferred_email)
>>> preferred_email.status
<DBItem EmailAddressStatus.PREFERRED...
>>> login(ANONYMOUS)
In the case of teams, though, the account_status is not changed as their
account_status must always be set to NOACCOUNT. (Notice how we use
setContactAddress() rather than setPreferredEmail() here, since the
latter can be used only for people and the former only for teams)
>>> team = factory.makeTeam(name='foo', displayname='foobaz')
>>> team.account_status
<DBItem AccountStatus.NOACCOUNT...
>>> email = emailset.new('foo@baz.com', team)
>>> team.setContactAddress(email)
>>> email.status
<DBItem EmailAddressStatus.PREFERRED...
>>> team.account_status
<DBItem AccountStatus.NOACCOUNT...
Unlike people, teams don't need a contact address, so we can pass None
to setContactAddress() to leave a team without a contact address.
>>> team.setContactAddress(None)
>>> print team.preferredemail
None
When a new sourcepackage is imported and a Person entry has to be
created because we don't know about the maintainer of that package, the
code to create the person should look like this:
>>> person, emailaddress = personset.createPersonAndEmail(
... 'random@random.com', PersonCreationRationale.SOURCEPACKAGEIMPORT,
... comment='when the ed package was imported into Ubuntu Breezy')
>>> person.is_valid_person
False
>>> person.creation_comment
u'when the ed package was imported into Ubuntu Breezy'
Checking .is_valid_person issues a DB query to the
ValidPersonOrTeamCache, unless it's already been cached. To avoid many
small queries when checking whether a lot of people are valid,
getValidPersons() can be used. This is useful for filling the ORM cache,
so that code in other places can check .is_valid_person, without it
issuing a DB query.
>>> non_valid_person = person
>>> non_valid_person.is_valid_person
False
>>> foobar.is_valid_person
True
>>> valid_persons = personset.getValidPersons([non_valid_person, foobar])
>>> [person.name for person in valid_persons]
[u'name16']
Accounts
........
A Person may be linked to an Account.
>>> login('no-priv@canonical.com')
>>> person = personset.getByEmail('no-priv@canonical.com')
>>> person.account.openid_identifiers.any().identifier
u'no-priv_oid'
Adapting an Account into a Person
.................................
And when the person is linked to an account, it's possible to adapt that
account into an IPerson.
>>> IPerson(person.account) == person
True
We can't adapt an account which has no person associated with, though.
>>> from lp.services.identity.interfaces.account import (
... AccountCreationRationale, IAccountSet)
>>> personless_account = getUtility(IAccountSet).new(
... AccountCreationRationale.UNKNOWN, 'Display name')
>>> print IPerson(personless_account, None)
None
Our security adapters expect to get passed an IPerson, but we use
IAccounts to represent logged in users, so we need to adapt them into
IPerson before passing that to the adapters. Since our Account table
has no reference to the Person table, the adaptation may end up hitting
the DB, which is something we don't want our security adapters to be
doing as they're called tons of times for every page we render. For
that reason, whenever there is a browser request, we will cache the
IPerson objects associated to the accounts we adapt.
Up to now there was no browser request we could use, so no caching was
done.
>>> from lp.services.webapp.servers import LaunchpadTestRequest
>>> request = LaunchpadTestRequest()
>>> print request.annotations.get('launchpad.person_to_account_cache')
None
Now we log in with the request so that whenever we adapt an account into
a Person, the Person is cached in the request.
>>> login('foo.bar@canonical.com', request)
>>> IPerson(person.account)
<Person...No Privileges Person)>
>>> cache = request.annotations.get('launchpad.person_to_account_cache')
>>> from zope.security.proxy import removeSecurityProxy
>>> cache[removeSecurityProxy(person.account)]
<Person...No Privileges Person)>
If we manually change the cache, the adapter will be fooled and will
return the wrong object.
>>> cache[removeSecurityProxy(person.account)] = 'foo'
>>> IPerson(person.account)
'foo'
If the cached value is None, though, the adapter will look up the
correct Person again and update the cache.
>>> cache[removeSecurityProxy(person.account)] = None
>>> IPerson(person.account)
<Person...No Privileges Person)>
>>> cache[removeSecurityProxy(person.account)]
<Person...No Privileges Person)>
Personal standing
.................
People have a property called 'personal standing', which affects for
example their ability to post to mailing lists they are not members of.
It's a form of automatic moderation. Most people have unknown standing,
which is the default.
>>> login('foo.bar@canonical.com')
>>> lifeless = personset.getByName('lifeless')
>>> lifeless.personal_standing
<DBItem PersonalStanding.UNKNOWN...
A person also has a reason for why their standing is what it is. The
default value of None means that no reason for the personal_standing
value is available.
>>> print lifeless.personal_standing_reason
None
A Launchpad administrator may change a person's standing, and may give a
reason for the change.
>>> from lp.registry.interfaces.person import PersonalStanding
>>> lifeless.personal_standing = PersonalStanding.GOOD
>>> lifeless.personal_standing_reason = 'Such a cool guy!'
>>> lifeless.personal_standing
<DBItem PersonalStanding.GOOD...
>>> print lifeless.personal_standing_reason
Such a cool guy!
Non-administrators may not change a person's standing.
>>> login('test@canonical.com')
>>> lifeless.personal_standing = PersonalStanding.POOR
Traceback (most recent call last):
...
Unauthorized: ...
>>> lifeless.personal_standing_reason = 'Such a cool guy!'
Traceback (most recent call last):
...
Unauthorized: ...
>>> login('foo.bar@canonical.com')
>>> lifeless.personal_standing
<DBItem PersonalStanding.GOOD...
>>> print lifeless.personal_standing_reason
Such a cool guy!
>>> login(ANONYMOUS)
Ubuntu Code of Conduct signees
..............................
Some people have signed the latest version of the Ubuntu Code of Conduct
and others have not.
>>> foobar.is_ubuntu_coc_signer
True
>>> lifeless.is_ubuntu_coc_signer
False
Teams
-----
As we said above, the Person class is overloaded to represent teams so
we may have Person objects which are, in fact, teams. To find out
whether a given object is a person or a team we can use the is_team
property of IPerson or check if the object provides the ITeam interface.
>>> from lp.registry.interfaces.person import ITeam
>>> ddaa = personset.getByName('ddaa')
>>> ddaa.is_team
False
>>> ITeam.providedBy(ddaa)
False
>>> landscape_devs = personset.getByName('landscape-developers')
>>> landscape_devs.is_team
True
>>> ITeam.providedBy(landscape_devs)
True
>>> verifyObject(ITeam, landscape_devs)
True
Also note that a team will never have a Launchpad account, so its
account_status will always be NOACCOUNT.
>>> landscape_devs.account_status
<DBItem AccountStatus.NOACCOUNT...
Creating teams
..............
Teams are created by the IPersonSet.newTeam() method, which takes the
team owner and some of the team's details, returning the newly created
team.
>>> new_team = personset.newTeam(ddaa, 'new-team', 'Just a new team')
>>> new_team.name
u'new-team'
>>> new_team.teamowner.name
u'ddaa'
If the given name is already in use by another team/person, an exception
is raised.
>>> personset.newTeam(ddaa, 'ddaa', 'Just a new team')
Traceback (most recent call last):
...
NameAlreadyTaken:...
PersonSet.newTeam() will also fire an ObjectCreatedEvent for the newly
created team.
>>> from zope.lifecycleevent.interfaces import IObjectCreatedEvent
>>> from lp.testing.event import TestEventListener
>>> def print_event(team, event):
... print "ObjectCreatedEvent fired for team '%s'" % team.name
>>> listener = TestEventListener(
... ITeam, IObjectCreatedEvent, print_event)
>>> another_team = personset.newTeam(ddaa, 'new3', 'Another a new team')
ObjectCreatedEvent fired for team 'new3'
>>> listener.unregister()
Turning people into teams
.........................
Launchpad may create Person entries automatically and it always assumes
these are actual people. Sometimes, though, these should actually be
teams, so we provide an easy way to turn one of these auto created
entries into teams.
>>> not_a_person, dummy = personset.createPersonAndEmail(
... 'foo@random.com', PersonCreationRationale.SOURCEPACKAGEIMPORT,
... comment='when the ed package was imported into Ubuntu Feisty')
>>> transaction.commit()
>>> not_a_person.is_team
False
>>> not_a_person.is_valid_person
False
>>> not_a_person.account_status
<DBItem AccountStatus.NOACCOUNT...
# Empty stub.test_emails as later we'll want to show that no
# notifications are sent when we add the owner as a member of
# the team.
>>> from lp.services.mail import stub
>>> stub.test_emails = []
>>> not_a_person.convertToTeam(team_owner=ddaa)
>>> not_a_person.is_team
True
>>> ITeam.providedBy(not_a_person)
True
>>> verifyObject(ITeam, not_a_person)
True
>>> print removeSecurityProxy(not_a_person).password
None
The team owner is also added as an administrator of its team.
>>> [member.name for member in not_a_person.adminmembers]
[u'ddaa']
# As said previously, no notifications are sent when we add the
# team owner as a member of his team.
>>> transaction.commit()
>>> stub.test_emails
[]
And we can even add other members to our new team!
>>> login('foo.bar@canonical.com')
>>> ignored = not_a_person.addMember(lifeless, reviewer=ddaa)
>>> login(ANONYMOUS)
>>> [member.name for member in not_a_person.activemembers]
[u'ddaa', u'lifeless']
This functionality is only available for non-team Person entries whose
account_status is NOACCOUNT, though.
>>> ddaa.account_status
<DBItem AccountStatus.ACTIVE...
>>> ddaa.convertToTeam(team_owner=landscape_devs)
Traceback (most recent call last):
...
AssertionError: Only Person entries whose account_status is NOACCOUNT...
>>> not_a_person.convertToTeam(team_owner=landscape_devs)
Traceback (most recent call last):
...
AlreadyConvertedException: foo-v has already been converted to a team.
Team members
............
The relationship between a person and a team is stored in
TeamMemberships table. TeamMemberships have a status (which can be any
item of TeamMembershipStatus) and represent the current state of the
relationship between that person and that team. Only
TeamMembershipStatus with an ADMIN or APPROVED status are considered
active.
>>> [member.displayname for member in landscape_devs.approvedmembers]
[u'Guilherme Salgado']
>>> [member.displayname for member in landscape_devs.adminmembers]
[u'Sample Person']
The IPerson.activemembers property will always include all approved and
admin members of that team.
>>> [member.displayname for member in landscape_devs.activemembers]
[u'Guilherme Salgado', u'Sample Person']
TeamMemberships with a PROPOSED or INVITED status represent a
person/team which has proposed himself as a member or which has been
invited to join the team.
>>> [member.displayname for member in landscape_devs.proposedmembers]
[u'Foo Bar']
>>> [member.displayname for member in landscape_devs.invited_members]
[u'Launchpad Developers']
Similarly, we have IPerson.pendingmembers which includes both invited
and proposed members.
>>> [member.displayname for member in landscape_devs.pendingmembers]
[u'Foo Bar', u'Launchpad Developers']
Finally, we have EXPIRED and DEACTIVATED TeamMemberships, which
represent former (inactive) members of a team.
>>> [member.displayname for member in landscape_devs.expiredmembers]
[u'Karl Tilbury']
>>> [member.displayname for member in landscape_devs.deactivatedmembers]
[u'No Privileges Person']
We can get a list of all inactive members of a team with the
IPerson.inactivemembers property.
>>> [member.displayname for member in landscape_devs.inactivemembers]
[u'Karl Tilbury', u'No Privileges Person']
We can also iterate over the TeamMemberships themselves, which is useful
when we want to display details about them rather than just the member.
>>> [(membership.person.displayname, membership.status.name)
... for membership in landscape_devs.member_memberships]
[(u'Guilherme Salgado', 'APPROVED'), (u'Sample Person', 'ADMIN')]
>>> [(membership.person.displayname, membership.status.name)
... for membership in landscape_devs.getInvitedMemberships()]
[(u'Launchpad Developers', 'INVITED')]
>>> [(membership.person.displayname, membership.status.name)
... for membership in landscape_devs.getProposedMemberships()]
[(u'Foo Bar', 'PROPOSED')]
>>> [(membership.person.displayname, membership.status.name)
... for membership in landscape_devs.getInactiveMemberships()]
[(u'Karl Tilbury', 'EXPIRED'), (u'No Privileges Person', 'DEACTIVATED')]
An IPerson has an inTeam method to allow us to easily check if a person
is a member (directly or through other teams) of a team. It accepts an
object implementing IPerson, which is the common use case when checking
permissions.
>>> ddaa.is_valid_person
True
>>> vcs_imports = personset.getByName('vcs-imports')
>>> lifeless.inTeam(vcs_imports) and ddaa.inTeam(vcs_imports)
True
That method can also be used to check that a given IPerson is a member
of itself. We can do that because people and teams have
TeamParticipation entries for themselves.
>>> ddaa.inTeam(ddaa)
True
>>> ddaa.hasParticipationEntryFor(ddaa)
True
>>> vcs_imports.inTeam(vcs_imports)
True
>>> vcs_imports.hasParticipationEntryFor(vcs_imports)
True
Email notifications to teams
............................
If a team has a contact email address, all notifications we send to the
team will go to that address.
>>> login('no-priv@canonical.com')
>>> ubuntu_team = personset.getByName('ubuntu-team')
>>> ubuntu_team.preferredemail.email
u'support@ubuntu.com'
>>> from lp.services.mail.helpers import get_contact_email_addresses
>>> get_contact_email_addresses(ubuntu_team)
set(['support@ubuntu.com'])
On the other hand, if a team doesn't have a contact email address, all
notifications we send to the team will go to the preferred email of each
direct member of that team.
>>> vcs_imports.preferredemail is None
True
>>> sorted(member.preferredemail.email
... for member in vcs_imports.activemembers)
[u'david.allouche@canonical.com', u'foo.bar@canonical.com',
u'robertc@robertcollins.net']
>>> sorted(get_contact_email_addresses(vcs_imports))
['david.allouche@canonical.com', 'foo.bar@canonical.com',
'robertc@robertcollins.net']
Team Visibility
...............
A Team can have its visibility attribute set to
PersonVisibility.PUBLIC or PersonVisibility.PRIVATE.
PRIVATE teams are hidden from view from non-members but they are
allowed to actually do things in Launchpad.
The PublicPersonChoice for interface classes and the
validate_public_person for database classes only allow public teams to
be assigned to the specified field.
The validators will raise a PrivatePersonLinkageError exception if an
invalid team is passed to the constructor or is used to set one of the
attributes.
Private teams can be subscribed to bugs.
>>> login('foo.bar@canonical.com')
>>> from lp.bugs.interfaces.bug import IBugSet
>>> from lp.registry.interfaces.person import (
... IPersonSet, PersonVisibility)
>>> from lp.bugs.model.bugsubscription import BugSubscription
>>> person_set = getUtility(IPersonSet)
>>> bug_set = getUtility(IBugSet)
>>> bug = bug_set.get(1)
>>> guadamen = person_set.getByName('guadamen')
>>> salgado = personset.getByName('salgado')
>>> private_team = factory.makeTeam(salgado, name='private-team',
... displayname='Private Team',
... visibility=PersonVisibility.PRIVATE)
>>> private_team_owner = private_team.teamowner
>>> bug_subscription = BugSubscription(bug=bug, person=private_team,
... subscribed_by=guadamen)
And they can subscribe others to bugs.
>>> bug_subscription = BugSubscription(bug=bug, person=guadamen,
... subscribed_by=private_team)
Teams also have a 'private' attribute that is true if the team is
private and false for public teams. It is also false for people.
>>> private_team.private
True
>>> guadamen.private
False
>>> salgado.private
False
Latest Team Memberships
-----------------------
The key concept in displaying the latest team memberships is that the
team list is actually sorted by date joined.
>>> from zope.component import getUtility
>>> from lp.registry.interfaces.person import IPersonSet
>>> personset = getUtility(IPersonSet)
>>> foobar = personset.getByName('name16')
>>> membership_list = foobar.getLatestApprovedMembershipsForPerson()
>>> for membership in membership_list:
... print membership.datejoined
2009-07-09 11:58:38.122886+00:00
2008-05-14 12:07:14.227450+00:00
2007-01-17 14:13:39.692693+00:00
2006-05-15 22:23:29.062603+00:00
2005-10-13 13:03:41.668724+00:00
Searching
---------
You can search based on a person's name or displayname, or any of the
email addresses that belongs to a person using the methods provided by
IPersonSet.
While we don't have Full Text Indexes in the emailaddress table, we'll
be trying to match the text only against the beginning of an email
address:
# First we'll define a utility function to help us displaying
# the results.
>>> naked_emailset = removeSecurityProxy(getUtility(IEmailAddressSet))
>>> def print_people(results):
... for person in results:
... emails = [email.email
... for email in naked_emailset.getByPerson(person)]
... print "%s (%s): %s" % (
... person.displayname, person.name, emails)
>>> print_people(personset.find('ubuntu'))

By default, when searching only for people, any person whose account is
inactive is not included in the list, but we can tell findPerson to
include them as well.

Packages related to a person
----------------------------
To obtain the packages a person is related to, we can use:
1. getLatestMaintainedPackages(),
2. getLatestUploadedButNotMaintainedPackages(),
3. getLatestUploadedPPAPackages
The 1st will return the latest SourcePackageReleases related to a person
in which he is listed as the Maintainer. The second will return the
latest SourcePackageReleases a person uploaded (and where he isn't the
maintainer).
Both, 1st and 2nd methods, only consider sources upload to primary
archives.
The 3rd method returns SourcePackageReleases uploaded by the person in
question to any PPA.
>>> mark = personset.getByName('mark')
>>> for sprelease in mark.getLatestMaintainedPackages():
... print (sprelease.name,
... sprelease.upload_distroseries.fullseriesname,
... sprelease.version)
(u'alsa-utils', u'Debian Sid', u'1.0.9a-4')
(u'pmount', u'Ubuntu Hoary', u'0.1-2')
(u'netapplet', u'Ubuntu Warty', u'0.99.6-1')
(u'netapplet', u'Ubuntu Hoary', u'1.0-1')
(u'alsa-utils', u'Ubuntu Warty', u'1.0.8-1ubuntu1')
(u'mozilla-firefox', u'Ubuntu Warty', u'0.9')
(u'evolution', u'Ubuntu Hoary', u'1.0')
>>> for sprelease in mark.getLatestUploadedButNotMaintainedPackages():
... print (sprelease.name,
... sprelease.upload_distroseries.fullseriesname,
... sprelease.version)
(u'foobar', u'Ubuntu Breezy-autotest', u'1.0')
(u'cdrkit', u'Ubuntu Breezy-autotest', u'1.0')
(u'libstdc++', u'Ubuntu Hoary', u'b8p')
(u'cnews', u'Ubuntu Hoary', u'cr.g7-37')
(u'linux-source-2.6.15', u'Ubuntu Hoary', u'2.6.15.3')
(u'alsa-utils', u'Ubuntu Hoary', u'1.0.9a-4ubuntu1')
>>> mark_spreleases = mark.getLatestUploadedPPAPackages()
>>> for sprelease in mark_spreleases:
... print (sprelease.name,
... sprelease.version,
... sprelease.creator.name,
... sprelease.maintainer.name,
... sprelease.upload_archive.owner.name,
... sprelease.upload_distroseries.fullseriesname)
(u'iceweasel', u'1.0', u'mark', u'name16', u'mark', u'Ubuntu Warty')
We will change modify the first SourcePackageRelease to reproduce the
issue mentioned in bug 157303, where source with same creator and
maintainer got omitted from the results:
>>> any_spr = mark_spreleases[0]
>>> naked_spr = removeSecurityProxy(any_spr)
>>> naked_spr.maintainer = mark
>>> flush_database_updates()
>>> mark_spreleases = mark.getLatestUploadedPPAPackages()
>>> for sprelease in mark_spreleases:
... print (sprelease.name,
... sprelease.version,
... sprelease.creator.name,
... sprelease.maintainer.name,
... sprelease.upload_archive.owner.name,
... sprelease.upload_distroseries.fullseriesname)
(u'iceweasel', u'1.0', u'mark', u'mark', u'mark', u'Ubuntu Warty')
Packages a Person is subscribed to
----------------------------------
IPerson.getBugSubscriberPackages returns this list of packages, sorted
alphabetically by package name.
>>> login('no-priv@canonical.com')
>>> from lp.registry.interfaces.distribution import (
... IDistributionSet)
>>> no_priv = getUtility(IPersonSet).getByName('no-priv')
>>> ubuntu = getUtility(IDistributionSet).getByName('ubuntu')
>>> pmount = ubuntu.getSourcePackage('pmount')
>>> pmount.addBugSubscription(no_priv, no_priv)
<...StructuralSubscription object at ...>
>>> mozilla_firefox = ubuntu.getSourcePackage('mozilla-firefox')
>>> mozilla_firefox.addBugSubscription(no_priv, no_priv)
<...StructuralSubscription object at ...>
>>> [package.name for package in no_priv.getBugSubscriberPackages()]
[u'mozilla-firefox', u'pmount']
Pillars owned or driven by a person or team
-------------------------------------------
To obtain all distributions, project groups and projects owned or driven
by a person or team, we can use the getOwnedOrDrivenPillars() method of
IPerson. This method returns PillarNames ordered by distribution,
project groups and projects.
>>> login(ANONYMOUS)
>>> from lp.registry.interfaces.distribution import IDistribution
>>> from lp.registry.interfaces.product import IProduct
>>> from lp.registry.interfaces.projectgroup import IProjectGroup
>>> def print_pillar(pillarname):
... pillar = pillarname.pillar
... if IDistribution.providedBy(pillar):
... pillar_type = 'distribution'
... elif IProjectGroup.providedBy(pillar):
... pillar_type = 'project group'
... elif IProduct.providedBy(pillar):
... pillar_type = 'project'
... print "%s: %s (%s)" % (
... pillar_type, pillar.displayname, pillar.name)
>>> for pillarname in mark.getOwnedOrDrivenPillars():
... print_pillar(pillarname)
distribution: Debian (debian)
distribution: Gentoo (gentoo)
distribution: Kubuntu (kubuntu)
distribution: Red Hat (redhat)
project group: Apache (apache)
project: Derby (derby)
project: alsa-utils (alsa-utils)
>>> for pillarname in ubuntu_team.getOwnedOrDrivenPillars():
... print_pillar(pillarname)
distribution: Ubuntu (ubuntu)
distribution: ubuntutest (ubuntutest)
project: Tomcat (tomcat)
Project owned by a person or team
---------------------------------
To obtain active projects owned by a person or team, we can use the
getOwnedProjects() method of IPerson. This method returns projects
ordered by displayname.
>>> for project in mark.getOwnedProjects():
... print project.displayname
Derby
Tomcat
alsa-utils
The method does not return inactive projects.
>>> login('foo.bar@canonical.com')
>>> from lp.app.interfaces.launchpad import ILaunchpadCelebrities
>>> registry_member = factory.makePerson()
>>> celebs = getUtility(ILaunchpadCelebrities)
>>> registry = celebs.registry_experts
>>> ignored = registry.addMember(registry_member, registry.teamowner)
>>> login_person(registry_member)
>>> derby = getUtility(IProductSet).getByName('derby')
>>> derby.active = False
>>> for project in mark.getOwnedProjects():
... print project.displayname
Tomcat
alsa-utils
>>> for project in ubuntu_team.getOwnedProjects():
... print project.displayname
Tomcat
David does not own any projects.
>>> list(ddaa.getOwnedProjects())
[]
The results returned can be filtered by providing a token to refine the
search.
>>> for project in mark.getOwnedProjects(match_name='java'):
... print project.displayname
Tomcat
Searching for a non-existent project returns no matches.
>>> list(mark.getOwnedProjects(match_name='nosuchthing'))
[]
Languages
---------
Users can set their preferred languages, retrievable as
Person.languages.
>>> daf = personset.getByName('daf')
>>> carlos = personset.getByName('carlos')
>>> for language in carlos.languages:
... print language.code, language.englishname
ca Catalan
en English
es Spanish
To add new languages we use Person.addLanguage().
>>> from lp.services.worlddata.interfaces.language import ILanguageSet
>>> languageset = getUtility(ILanguageSet)
>>> carlos.addLanguage(languageset['pt_BR'])
>>> [lang.code for lang in carlos.languages]
[u'ca', u'en', u'pt_BR', u'es']
Adding a language which is already in the person's preferred ones will
be a no-op.
>>> carlos.addLanguage(languageset['es'])
>>> [lang.code for lang in carlos.languages]
[u'ca', u'en', u'pt_BR', u'es']
And to remove languages we use Person.removeLanguage().
>>> carlos.removeLanguage(languageset['pt_BR'])
>>> [lang.code for lang in carlos.languages]
[u'ca', u'en', u'es']
Trying to remove a language which is not in the person's preferred ones
will be a no-op.
>>> carlos.removeLanguage(languageset['pt_BR'])
>>> [lang.code for lang in carlos.languages]
[u'ca', u'en', u'es']
The Person.languages list is ordered alphabetically by the languages'
English names.
>>> for language in daf.languages:
... print language.code, language.englishname
en_GB English (United Kingdom)
ja Japanese
cy Welsh
Specification Lists
-------------------
We should be able to generate lists of specifications for people based
on certain criteria:
First, Carlos does not have any completed specifications assigned to
him:
>>> from lp.blueprints.enums import SpecificationFilter
>>> carlos.specifications(filter=[
... SpecificationFilter.ASSIGNEE,
... SpecificationFilter.COMPLETE]).count()
0
Next, Carlos has three incomplete specs *related* to him:
>>> filter = []
>>> for spec in carlos.specifications(filter=filter):
... print spec.name, spec.is_complete, spec.informational
svg-support False False
extension-manager-upgrades False True
media-integrity-check False False
Carlos has 2 specifications assigned to him:
>>> for spec in carlos.assigned_specs:
... print spec.name
svg-support
extension-manager-upgrades
But from these two, only one has started.
>>> [(spec.name, spec.is_started)
... for spec in carlos.assigned_specs_in_progress]
[(u'svg-support', True)]
Just for fun, lets check the SAB. He should have one spec for which he
is the approver.
>>> mark = getUtility(IPersonSet).getByName('mark')
>>> filter = [SpecificationFilter.APPROVER]
>>> for spec in mark.specifications(filter=filter):
... print spec.name
extension-manager-upgrades
The Foo Bar person has a single spec which has feedback requested:
>>> filter = [SpecificationFilter.FEEDBACK]
>>> for spec in foobar.specifications(filter=filter):
... print spec.name
e4x
But has registered 5 of them:
>>> filter = [SpecificationFilter.CREATOR]
>>> print foobar.specifications(filter=filter).count()
5
Now Celso, on the other hand, has 2 specs related to him:
>>> cprov = personset.getByName('cprov')
>>> cprov.specifications().count()
2
On one of those, he is the approver:
>>> filter = [SpecificationFilter.APPROVER]
>>> for spec in cprov.specifications(filter=filter):
... print spec.name
svg-support
And on another one, he is the drafter
>>> filter = [SpecificationFilter.DRAFTER]
>>> for spec in cprov.specifications(filter=filter):
... print spec.name
e4x
We can filter for specifications that contain specific text:
>>> for spec in cprov.specifications(filter=['svg']):
... print spec.name
svg-support
Inactive products are excluded from the listings.
>>> from lp.testing import login
>>> from lp.registry.interfaces.product import IProductSet
>>> firefox = getUtility(IProductSet).getByName('firefox')
>>> login("mark@example.com")
# Unlink the source packages so the project can be deactivated.
>>> from lp.testing import unlink_source_packages
>>> unlink_source_packages(firefox)
>>> firefox.active = False
>>> flush_database_updates()
>>> cprov.specifications(filter=['svg']).count()
0
Reset firefox so we don't mess up later tests.
>>> firefox.active = True
>>> flush_database_updates()
Branches
--------
** See branch.txt for API related to branches.
Distribution uploaders
----------------------
We can ascertain whether a person has uploader rights to a distribution
or not.
>>> cprov = getUtility(IPersonSet).getByName('cprov')
>>> ubuntu = getUtility(IDistributionSet)['ubuntu']
>>> cprov.isUploader(ubuntu)
True
'kiko' is not an uploader to Ubuntu:
>>> kiko = getUtility(IPersonSet).getByName('kiko')
>>> kiko.isUploader(ubuntu)
False
Bug contribution
----------------
We can check whether a person has any bugs assigned to them, either
within the context of a specific bug target, or in Launchpad in general.
A person with bugs assigned to them in a context is considered a 'Bug
Contributor'.
>>> from lp.bugs.interfaces.bugtask import BugTaskSearchParams
>>> cprov.searchTasks(
... BugTaskSearchParams(user=foobar, assignee=cprov)).count()
0
Celso has no bug tasks assigned to him. In other words, he isn't a bug
contributor.
>>> cprov.isBugContributor(user=foobar)
False
We assign a bug task to Celso.
>>> from lp.bugs.interfaces.bugtask import IBugTaskSet
>>> search_params = BugTaskSearchParams(user=foobar)
>>> search_params.setProduct(firefox)
>>> firefox_bugtask = getUtility(IBugTaskSet).search(search_params)[0]
>>> firefox_bugtask.transitionToAssignee(cprov)
>>> flush_database_updates()
Now Celso is a bug contributor in Launchpad.
>>> cprov.isBugContributor(user=foobar)
True
Celso is a bug contributer in the context of the `firefox` product.
>>> from lp.registry.interfaces.projectgroup import IProjectGroupSet
>>> cprov.isBugContributorInTarget(user=foobar, target=firefox)
True
And also in the context of the `mozilla` project, by association.
>>> cprov.isBugContributorInTarget(user=foobar,
... target=getUtility(IProjectGroupSet).getByName('mozilla'))
True
But not in other contexts.
>>> cprov.isBugContributorInTarget(user=foobar,
... target=getUtility(IProductSet).getByName('jokosher'))
False
Creating a Person without an email address
------------------------------------------
Although createPersonAndEmail() is the usual method to use when creating
a new Person, there is also a method that can be used when a Person
needs to be created without an email address, for example when the
Person is being created as the result of an import from an external
bugtracker.
The method createPersonWithoutEmail() is used in these situations. This
takes some parameters similar to those taken by createPersonAndEmail()
but, since an emailless Person cannot be considered to be valid, it
takes no parameters regarding to emails or passwords.
>>> foo_bar = getUtility(IPersonSet).getByEmail('foo.bar@canonical.com')
>>> new_person = person_set.createPersonWithoutEmail(
... 'ix', PersonCreationRationale.BUGIMPORT,
... comment="when importing bugs", displayname="Ford Prefect",
... registrant=foo_bar)
>>> print new_person.name
ix
>>> print new_person.displayname
Ford Prefect
>>> print new_person.preferredemail
None
>>> print new_person.creation_rationale.name
BUGIMPORT
>>> print new_person.registrant.name
name16
The _newPerson() method
-----------------------
The PersonSet database class has a method _newPerson(), which is used to
create new Person objects. This isn't exposed in the interface, so to
test it we need to instantiate PersonSet directly.
>>> from lp.registry.model.person import PersonSet
>>> person_set = PersonSet()
_newPerson() accepts parameters for name displayname and rationale. It
also takes the parameters hide_email_addresses, comment and registrant.
>>> person_set._newPerson(
... 'new-name', 'New Person', True,
... PersonCreationRationale.BUGIMPORT, "testing _newPerson().",
... foo_bar)
<Person at ...>
If the name passed to _newPerson() is already taken, a NameAlreadyTaken
error will be raised.
>>> person_set._newPerson(
... 'new-name', 'New Person', True,
... PersonCreationRationale.BUGIMPORT)
Traceback (most recent call last):
...
NameAlreadyTaken: The name 'new-name' is already taken.
If the name passed to _newPerson() isn't valid an InvalidName error will
be raised.
>>> person_set._newPerson(
... "ThisIsn'tValid", 'New Person', True,
... PersonCreationRationale.BUGIMPORT)
Traceback (most recent call last):
...
InvalidName: ThisIsn'tValid is not a valid name for a person.
Probationary users
------------------
Users without karma have not demostrated their intentions and may not
have the same privileges as users who have made contributions. Users who
have made recent contributions are not on probation.
>>> active_user = personset.getByName('name12')
>>> active_user.is_probationary
False
>>> active_user.karma > 0
True
>>> active_user.is_valid_person
True
New users (those without karma) are on probation.
>>> new_user = factory.makePerson()
>>> new_user.is_probationary
True
>>> new_user.karma > 0
False
>>> new_user.is_valid_person
True
Teams are never on probation.
>>> team = factory.makeTeam()
>>> team.is_probationary
False
>>> team.karma > 0
False
>>> team.is_valid_person
False
