Types ¶
type ChildHandle ¶
type ChildHandle struct {
WSURL string // ws://127.0.0.1:PORT
HTTPURL string // http://127.0.0.1:PORT (for /readyz, /healthz)
CodexHome string
// contains filtered or unexported fields
}
ChildHandle is what spawnCodexAppServer returns.
func (*ChildHandle) Done ¶
func (h *ChildHandle) Done() <-chan struct{}
Done returns a channel closed after the subprocess exits. Useful for callers that want to be notified of unexpected termination.
func (*ChildHandle) IsAlive ¶
func (h *ChildHandle) IsAlive() bool
IsAlive reports whether the subprocess is still running. Cheap; suitable for calling on every EnsureSubprocess hit.
type ConfigBuilder ¶
type ConfigBuilder func() (codexhome.ConfigInput, error)
ConfigBuilder produces a fresh ConfigInput at spawn time. Allowed to hit the network; errors propagate.
type IdleReaper ¶
type IdleReaper struct {
// contains filtered or unexported fields
}
IdleReaper periodically scans the Supervisor and shuts down entries idle for longer than idleAfter.
func NewIdleReaper ¶
func NewIdleReaper(sup *Supervisor, interval, idleAfter time.Duration, logger *slog.Logger) *IdleReaper
func (*IdleReaper) Run ¶
func (r *IdleReaper) Run(ctx context.Context)
Run blocks until ctx is done, ticking every interval and shutting down idle entries.
type Supervisor ¶
type Supervisor struct {
// contains filtered or unexported fields
}
Supervisor owns the in-memory (workspace, thread) → subprocess map.
func NewSupervisor ¶
func NewSupervisor(cfg SupervisorConfig) *Supervisor
func (*Supervisor) EnsureSubprocess ¶
func (s *Supervisor) EnsureSubprocess(ctx context.Context, key Key, build ConfigBuilder) (*ChildHandle, error)
EnsureSubprocess returns a live ChildHandle for key, spawning one if necessary. Concurrent EnsureSubprocess calls for the same key see the same handle (one-spawn-per-key invariant; loser of the race discards their spawn). If a cached entry's subprocess has crashed, it is evicted and a fresh subprocess is spawned.
func (*Supervisor) Shutdown ¶
func (s *Supervisor) Shutdown(ctx context.Context, key Key) error
Shutdown terminates the subprocess for key, uploads its CODEX_HOME to S3, and drops the in-memory entry. Safe on missing keys.
func (*Supervisor) ShutdownAll ¶
func (s *Supervisor) ShutdownAll(ctx context.Context)
ShutdownAll shuts down every active subprocess.
func (*Supervisor) Touch ¶
func (s *Supervisor) Touch(key Key)
Touch bumps the last-active timestamp for a key. Callers must invoke it on every proxied frame (see proxy.RunProxy's onFrame callback) so the IdleReaper sees fresh activity for the duration of an active session, not just at connect/disconnect.
type SupervisorConfig ¶
type SupervisorConfig struct {
CodexBin string
HomeMgr *codexhome.Manager
Store codexhome.ObjectStore
ExtraEnv []string // forwarded to every spawned subprocess
Logger *slog.Logger // defaults to slog.Default() if nil
}
SupervisorConfig holds the static dependencies.
