Constants ¶
const ( // ConflictInterval is how often the daemon re-evaluates whether each // project's branch still merges cleanly. Far slower than PollInterval // because the answer only changes when a commit lands on either side, and // the check costs a merge in the object database rather than a stat. ConflictInterval = 60 * time.Second // FetchInterval is how often the merge target's remote-tracking ref is // refreshed. The check is worthless against a ref nobody has updated in a // week, and expensive if refreshed every time: this is the compromise. FetchInterval = 3 * time.Minute // MaxConflictPaths caps the paths reported for one branch. A merge that // conflicts in hundreds of files is one fact — "this branch has diverged // badly" — and listing all of them buries it. MaxConflictPaths = 20 )
const ( // PollInterval is how often the daemon refreshes project state from disk. PollInterval = 5 * time.Second // RecentEvents is the maximum number of events kept per project. RecentEvents = 300 // RunningTimeout is how long after the last non-terminal event a sidecar is // considered to still be running. RunningTimeout = 5 * time.Minute )
const ( // MaxCommandBytes is the default per-command output buffer cap in bytes. // Override at runtime with CHUNK_OUTPUT_BUFFER_SIZE so the cap can be tuned // via a sandbox-provisioner deploy without rebuilding images. MaxCommandBytes = 10 << 20 // 10 MB // MaxCommands caps retained commands per project. Only finished commands are // evicted, so a project running more than this many at once keeps them all. MaxCommands = 20 )
const DefaultAsyncMaxLines = 500
DefaultAsyncMaxLines is how large a change may be, in lines, and still be validated in the background.
The number is a judgement, not a measurement. What it is really choosing is how much of the inner loop runs without waiting: nearly every edit an agent makes in one turn lands under it, and the changes that do not are the ones where a developer is most likely to want the answer before doing anything else. Projects that disagree can say so — see config.AsyncValidateMaxLines.
const DefaultAttempts = 3
DefaultAttempts is how many rounds a factory session checks at most when the request does not say.
const MaxSessionsPerProject = 10
MaxSessionsPerProject caps retained sessions per project. Only finished ones are evicted, so a live session is never lost.
const MaxTasksPerProject = 20
MaxTasksPerProject caps retained validation tasks per project. Only finished tasks are evicted, so a project cannot lose a run that is still going. It is also what bounds delivered results, which collect keeps rather than deletes.
const PRPollInterval = 60 * time.Second
PRPollInterval is the minimum time between PR fetches for a given branch. GitHub's API is rate-limited, so polling too frequently is wasteful. A branch change resets the clock so the new branch's PR is fetched promptly.

Functions ¶
func RunDaemon ¶
func RunDaemon(ctx context.Context, client *circleci.Client, authMessage string, runner ValidateRunner, ghClient *github.Client, opts ...Option) error
RunDaemon is the chunk daemon entry point, called by the hidden _daemon subcommand.
client and authMessage support the output-buffering feature; runner is called in-process to handle /validate requests. Both client and runner may be nil (the daemon still records commands without a client, and /validate returns an error without a runner). ghClient may be nil; PR monitoring is skipped when no GitHub credentials are available.
Types ¶
type Option ¶
type Option func(*daemonOptions)
Option customizes RunDaemon.
func WithReview ¶
func WithReview(cfg ReviewConfig) Option
WithReview configures the daemon's review capability.
type ReviewConfig ¶
type ReviewConfig struct {
Credential claudecode.Credential
// BaseURL is forwarded to claude when it is not Anthropic's own.
BaseURL string
// AuthError explains a missing Credential, reported in the snapshot so an
// absent capability is explained rather than silent.
AuthError string
// The fields below are test seams. Left nil, the daemon talks to the
// sandbox through the pool entry's own client.
Submit SubmitFunc
Stream StreamFunc
// RunFactory runs a factory session; factory.Run when nil.
RunFactory func(ctx context.Context, opts factory.RunOptions) (factory.Report, error)
}
ReviewConfig is everything the daemon needs to run factory sessions. The credential is resolved once by the caller at daemon start; it is only ever placed in the environment of a Claude command, and never logged or put in a snapshot.
type StreamFunc ¶
type StreamFunc func(ctx context.Context, entry *sidecar.PoolEntry, commandID string, onOutput circleci.OutputFn) (int, error)
StreamFunc reads a submitted command's output to its end and returns its exit code.
type SubmitFunc ¶
type SubmitFunc func(ctx context.Context, entry *sidecar.PoolEntry, script string, env map[string]string) (string, error)
SubmitFunc submits a script on a pool member and returns its command ID.
type ValidateRunner ¶
type ValidateRunner func(ctx context.Context, projectRoot, workDir string, args []string, env []string, stdout, stderr io.Writer) int
ValidateRunner runs a validate command in-process. projectRoot is the repo the daemon uses for task tracking and state keying; workDir is the caller's working directory, passed to the subprocess as --project so it can load .chunk/config.json from the right location (workDir equals projectRoot unless the .chunk directory sits below the git root, in which case workDir is the subdirectory and projectRoot is the git top-level). When workDir is empty the runner falls back to projectRoot. args is os.Args[1:] from the caller; env is the caller's os.Environ(). stdout and stderr capture command output. Returns the exit code.
