// Why this throttle exists:
|
|
//
|
|
// Worktree creation, cleanup, and submodule init all shell out to git in
|
|
// quick succession (worktree add, branch -D, worktree prune, submodule
|
|
// update --init --recursive, ...). When multiple agents start at once the
|
|
// number of concurrent git execs can climb past 30, and on managed
|
|
// corporate macOS hosts (CrowdStrike Falcon + syspolicyd) every fork/exec
|
|
// is intercepted, serialized, and validated. The resulting backlog has
|
|
// been observed alongside the gh-poller storm — see internal/common/
|
|
// subproc for the full rationale. This file just provides short
|
|
// package-local wrappers so callers don't have to reach into subproc
|
|
// for every git exec.
|
|
|
|
// runGitCmd acquires a git slot, runs cmd, and releases. Use this
|
|
// anywhere we exec a git binary from the worktree package — calling
|
|
// cmd.Run() directly bypasses the throttle.
