3.8.8. Changes connector

class buildbot.db.changes.ChangesConnectorComponent

This class handles changes in the Buildbot database, including pulling information from the changes sub-tables.

An instance of this class is available at master.db.changes.

Changes are indexed by changeid, and are represented by a ChangeModel dataclass, which has the following fields:

  • changeid (the ID of this change)

  • parent_changeids (list of ID; change’s parents)

  • author (unicode; the author of the change)

  • committer (unicode; the committer of the change)

  • files (list of unicode; source-code filenames changed)

  • comments (unicode; user comments)

  • is_dir (deprecated)

  • links (list of unicode; links for this change, e.g., to web views, review)

  • revision (unicode string; revision for this change, or None if unknown)

  • when_timestamp (datetime instance; time of the change)

  • branch (unicode string; branch on which the change took place, or None for the “default branch”, whatever that might mean)

  • category (unicode string; user-defined category of this change, or None)

  • revlink (unicode string; link to a web view of this change)

  • properties (user-specified properties for this change, represented as a dictionary mapping keys to (value, source))

  • repository (unicode string; repository where this change occurred)

  • project (unicode string; user-defined project to which this change corresponds)

getParentChangeIds(branch, repository, project, codebase)
Parameters:

  • branch (unicode string) – the branch of the change

  • repository (unicode string) – the repository in which this change took place

  • project (unicode string) – the project this change is a part of

  • codebase (unicode string)

Returns:

the last changeID that matches the branch, repository, project, or codebase

addChange(author=None, committer=None, files=None, comments=None, is_dir=0, links=None, revision=None, when_timestamp=None, branch=None, category=None, revlink='', properties={}, repository='', project='', uid=None)
Parameters:

  • author (unicode string) – the author of this change

  • committer (unicode string) – the committer of this change

  • files – a list of filenames that were changed

  • comments – user comments on the change

  • is_dir – deprecated

  • links (list of unicode strings) – a list of links related to this change, e.g., to web viewers or review pages

  • revision (unicode string) – the revision identifier for this change

  • when_timestamp (datetime instance or None) – when this change occurred, or the current time if None

  • branch (unicode string) – the branch on which this change took place

  • category (unicode string) – category for this change (arbitrary use by Buildbot users)

  • revlink (unicode string) – link to a web view of this revision

  • properties (dictionary) – properties to set on this change, where values are tuples of (value, source). At the moment, the source must be 'Change', although this may be relaxed in later versions

  • repository (unicode string) – the repository in which this change took place

  • project (unicode string) – the project this change is a part of

  • uid (integer) – uid generated for the change author

Returns:

new change’s ID via Deferred

Add a Change with the given attributes to the database, returning the changeid via a Deferred. All arguments should be given as keyword arguments.

The project and repository arguments must be strings; None is not allowed.

getChange(changeid, no_cache=False)
Parameters:

  • changeid – the id of the change instance to fetch

  • no_cache (boolean) – bypass cache and always fetch from database

Returns:

ChangeModel or None, via Deferred

Get a ChangeModel for the given changeid, or None if no such change exists.

getChangeUids(changeid)
Parameters:

changeid – the id of the change instance to fetch

Returns:

list of uids via Deferred

Get the userids associated with the given changeid.

getChanges(resultSpec=None)
Parameters:

resultSpec – result spec containing filters sorting and paging requests from data/REST API. If possible, the db layer can optimize the SQL query using this information.

Returns:

list of ChangeModel via Deferred

Get a list of the changes, represented as ChangeModel, matching the given criteria. if resultSpec is not provided, changes are sorted, and paged using generic data query options.

getChangesCount()
Returns:

list of dictionaries via Deferred

Get the number of changes that the query option would return if no paging option was set.

getLatestChangeid()
Returns:

changeid via Deferred

Get the most-recently-assigned changeid, or None if there are no changes at all.

getChangesForBuild(buildid)
Parameters:

buildid – ID of the build

Returns:

list of ChangeModel via Deferred

Get the “blame” list of changes for a build.

getBuildsForChange(changeid)
Parameters:

changeid – ID of the change

Returns:

list of ChangeModel via Deferred

Get builds related to a change.

getChangeFromSSid(sourcestampid)
Parameters:

sourcestampid – ID of the sourcestampid

Returns:

ChangeModel via Deferred

Returns the ChangeModel related to the sourcestamp ID.
