Functions ¶
func GetBigQueryAlerts ¶
GetBigQueryAlerts generates alerts for currently failing build steps, using BigQuery to do most of the heavy lifting. Note that this returns alerts for all failing steps, so filtering should be applied on the return value. TODO: Some post-bq result merging with heuristics:
- Merge alerts for sets of multiple failing steps. Currently will return one alert for each failing step on a builder. If step_a and step_b are failing on the same builder or set of builders, they should be merged into a single alert.
Types ¶
type Analyzer ¶
type Analyzer struct {
// MaxRecentBuilds is the maximum number of recent builds to check, per builder.
MaxRecentBuilds int
// MinRecentBuilds is the minimum number of recent builds to check, per builder.
MinRecentBuilds int
// HungBuilerThresh is the maxumum length of time a builder may be in state "building"
// before triggering a "hung builder" alert.
HungBuilderThresh time.Duration
// OfflineBuilderThresh is the maximum length of time a builder may be in state "offline"
// before triggering an "offline builder" alert.
OfflineBuilderThresh time.Duration
// IdleBuilderCountThresh is the maximum number of builds a builder may have in queue
// while in the "idle" state before triggering an "idle builder" alert.
IdleBuilderCountThresh int64
// Now is useful for mocking the system clock in testing and simulating time
// during replay.
Now func() time.Time
// Mock these out in tests.
CrBug client.CrBug
FindIt client.FindIt
// contains filtered or unexported fields
}
Analyzer runs the process of checking builder groups, builders, test results and so on, in order to produce alerts.
func CreateAnalyzer ¶
CreateAnalyzer creates a new analyzer and set its service clients.
func New ¶
New returns a new Analyzer. If client is nil, it assigns a default implementation. maxBuilds is the maximum number of builds to check, per builder.
func (*Analyzer) GetRevisionSummaries ¶
func (a *Analyzer) GetRevisionSummaries(hashes []string) ([]*messages.RevisionSummary, error)
GetRevisionSummaries returns a slice of RevisionSummaries for the list of hashes.
type BuilderGroupConfig ¶
type BuilderGroupConfig struct {
ExcludedBuilders []string `json:"excluded_builders"`
}
BuilderGroupConfig is a parsed representation of the inner per builder group value, which contains a list of builders to exclude for that builder group.
type ConfigRules ¶
type ConfigRules struct {
IgnoredSteps []string `json:"ignored_steps"`
BuilderGroupCfgs map[string]BuilderGroupConfig `json:"builder_groups"`
}
ConfigRules is a parsed representation of the config.json file, which specifies builders and steps to exclude.
func GetConfigRules ¶
func GetConfigRules(c context.Context) (*ConfigRules, error)
GetConfigRules fetches the latest version of the config from Gitiles.
func ParseConfigRules ¶
func ParseConfigRules(cfgJSON []byte) (*ConfigRules, error)
ParseConfigRules parses the given byte array into a ConfigRules object. Public so that parse_config_test can use it.
func (*ConfigRules) ExcludeFailure ¶
func (r *ConfigRules) ExcludeFailure(ctx context.Context, builderGroup, builder, step string) bool
ExcludeFailure determines whether a particular failure should be ignored, according to the rules in the config.
type GitCommit ¶
type GitCommit struct {
Project bigquery.NullString
Ref bigquery.NullString
Host bigquery.NullString
ID bigquery.NullString
Position bigquery.NullInt64
}
GitCommit represents a struct column for BQ query results.
