Buildbot no longer supports Python 2.7 on the Buildbot master.
3.8.2. Buildrequests connector¶
Raised when a build request is already claimed, usually by another master.
Raised when a build request is not claimed by this master.
This class handles the complex process of claiming and unclaiming build requests, based on a polling model: callers poll for unclaimed requests with
getBuildRequests, then attempt to claim the requests with
claimBuildRequests. The claim can fail if another master has claimed the request in the interim.
An instance of this class is available at
Build requests are indexed by an ID referred to as a brid. The contents of a request are represented as build request dictionaries (brdicts) with keys
claimed(boolean, true if the request is claimed)
claimed_at(datetime object, time this request was last claimed)
claimed_by_masterid(integer, the id of the master that claimed this buildrequest)
complete(boolean, true if the request is complete)
complete_at(datetime object, time this request was completed)
submitted_at(datetime object, time this request was completed)
results(integer result code)
brid – build request id to look up
None, via Deferred
Get a single BuildRequest, in the format described above. This method returns
Noneif there is no such buildrequest. Note that build requests are not cached, as the values in the database are not fixed.
getBuildRequests(buildername=None, complete=None, claimed=None, bsid=None, branch=None, repository=None, resultSpec=None)¶
buildername (string) – limit results to buildrequests for this builder
complete – if true, limit to completed buildrequests; if false, limit to incomplete buildrequests; if
None, do not limit based on completion.
claimed – see below
bsid – see below
repository – the repository associated with the sourcestamps originating the requests
branch – the branch associated with the sourcestamps originating the requests
resultSpec – resultSpec containing filters sorting and paging request from data/REST API. If possible, the db layer can optimize the SQL query using this information.
list of brdicts, via Deferred
Get a list of build requests matching the given characteristics.
Pass all parameters as keyword parameters to allow future expansion.
claimedparameter can be
None(the default) to ignore the claimed status of requests;
Trueto return only claimed builds,
Falseto return only unclaimed builds, or a
master IDto return only builds claimed by a particular master instance. A request is considered unclaimed if its
claimed_atcolumn is either NULL or 0, and it is not complete. If
bsidis specified, then only build requests for that buildset will be returned.
A build is considered completed if its
completecolumn is 1; the
complete_atcolumn is not consulted.
brids (list) – ids of buildrequests to claim
claimed_at (datetime) – time at which the builds are claimed
Try to “claim” the indicated build requests for this buildmaster instance. The resulting deferred will fire normally on success, or fail with
AlreadyClaimedErrorif any of the build requests are already claimed by another master instance. In this case, none of the claims will take effect.
claimed_atis not given, then the current time will be used.
On database backends that do not enforce referential integrity (e.g., SQLite), this method will not prevent claims for nonexistent build requests. On database backends that do not support transactions (MySQL), this method will not properly roll back any partial claims made before an
brids (list) – ids of buildrequests to unclaim
Release this master’s claim on all of the given build requests. This will not unclaim requests that are claimed by another master, but will not fail in this case. The method does not check whether a request is completed.
completeBuildRequests(brids, results[, complete_at=XX])¶
brids (integer) – build request IDs to complete
results (integer) – integer result code
complete_at (datetime) – time at which the buildset was completed
Complete a set of build requests, all of which are owned by this master instance. This will fail with
NotClaimedErrorif the build request is already completed or does not exist. If
complete_atis not given, the current time will be used.
