replace(spec, checksum) 点击切换源代码

当新校验和来自同一来源时进行替换。主要目的是注册来自索引中存在重复 gem （根据 full_name）的 gem 的校验和。

特别地，当 2 个 gem 有两个相似的平台时，例如 “darwin20” 和 “darwin-20”，它们都解析为 darwin-20。在 Index 中，后面的 gem 替换了前面的 gem，所以我们在这里也这样做。

但是，如果新的校验和来自不同的来源，我们将像往常一样注册。这确保了在存在多个包含具有不同校验和的相同 gem 的顶级源的情况下发生不匹配错误。

# File bundler/checksum.rb, line 190
def replace(spec, checksum)
  return unless checksum

  lock_name = spec.name_tuple.lock_name
  @store_mutex.synchronize do
    existing = fetch_checksum(lock_name, checksum.algo)
    if !existing || existing.same_source?(checksum)
      store_checksum(lock_name, checksum)
    else
      merge_checksum(lock_name, checksum, existing)
