From 1ea57a7dbf4d34045a361e9bba9191de06cd1749 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 24 May 2026 17:42:45 +0000 Subject: refactor(executor): delete unused ClaudeRunner; keep sandbox helpers (Phase 2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ClaudeRunner was never instantiated in production (serve.go wires only ContainerRunner) and was not wired for MCP. Remove it and its CLI/buildArgs/ execOnce tests. The sandbox helpers it defined (sandboxCloneSource, setupSandbox, teardownSandbox) are still used by GeminiRunner, so they move to sandbox.go; their tests (plus the shared initGitRepo helper and the tailFile test) move to sandbox_test.go. No production behavior change — this removes dead code and the last file-based agent wire that lived in ClaudeRunner. https://claude.ai/code/session_01SESwn7kQ7oP62trWw6pc39 --- internal/executor/claude.go | 552 -------------------------- internal/executor/claude_test.go | 810 -------------------------------------- internal/executor/sandbox.go | 187 +++++++++ internal/executor/sandbox_test.go | 366 +++++++++++++++++ 4 files changed, 553 insertions(+), 1362 deletions(-) delete mode 100644 internal/executor/claude.go delete mode 100644 internal/executor/claude_test.go create mode 100644 internal/executor/sandbox.go create mode 100644 internal/executor/sandbox_test.go diff --git a/internal/executor/claude.go b/internal/executor/claude.go deleted file mode 100644 index 0123754..0000000 --- a/internal/executor/claude.go +++ /dev/null @@ -1,552 +0,0 @@ -package executor - -import ( - "context" - "fmt" - "log/slog" - "os" - "os/exec" - "path/filepath" - "strings" - "sync" - "syscall" - "time" - - "github.com/thepeterstone/claudomator/internal/retry" - "github.com/thepeterstone/claudomator/internal/storage" - "github.com/thepeterstone/claudomator/internal/task" -) - -// ClaudeRunner spawns the `claude` CLI in non-interactive mode. -type ClaudeRunner struct { - BinaryPath string // defaults to "claude" - Logger *slog.Logger - LogDir string // base directory for execution logs - APIURL string // base URL of the Claudomator API, passed to subprocesses -} - -// BlockedError is returned by Run when the agent wrote a question file and exited. -// The pool transitions the task to BLOCKED and stores the question for the user. -// ExecLogDir returns the log directory for the given execution ID. -// Implements LogPather so the pool can persist paths before execution starts. -func (r *ClaudeRunner) ExecLogDir(execID string) string { - if r.LogDir == "" { - return "" - } - return filepath.Join(r.LogDir, execID) -} - -func (r *ClaudeRunner) binaryPath() string { - if r.BinaryPath != "" { - return r.BinaryPath - } - return "claude" -} - -// Run executes a claude -p invocation, streaming output to log files. -// It retries up to 3 times on rate-limit errors using exponential backoff. -// If the agent writes a question file and exits, Run returns *BlockedError. -// -// When project_dir is set and this is not a resume execution, Run clones the -// project into a temp sandbox, runs the agent there, then merges committed -// changes back to project_dir.
