研究方向

從公開的 node:fs 和 node:fs/promises API 以及現有的 node:diagnostics_channel TracingChannel 慣例入手;比較 sync、callback、promise、stream 和 filehandle 路徑。確定發布層和 channel 名稱,同時讓 payload 不依賴 FSReqCallback 細節。完成標準是:受支援的公開檔案系統操作會發布文件所述的生命週期事件和中繼資料。

描述

feature request
What is the problem this feature will solve?

node:diagnostics_channel does not currently expose a built-in channel for filesystem operations performed through node:fs and node:fs/promises.

The proposed scope is the public filesystem APIs. Calls made directly by native addons or arbitrary native code do not need to be included in this contract.

What is the feature you are proposing to solve the problem?

Add a built-in tracing channel family for filesystem operations. One possible naming scheme is:

  • tracing:fs.operation:start
  • tracing:fs.operation:end
  • tracing:fs.operation:asyncStart
  • tracing:fs.operation:asyncEnd
  • tracing:fs.operation:error

The shared event object could contain:

  • operation: a stable operation name such as open, read, stat, readdir, or realpath.
  • api: sync, callback, promise, stream, or filehandle.
  • Path, source/destination, or file descriptor fields when applicable, preserving the value type passed by the caller.
  • result and error following the existing TracingChannel conventions.

Large read/write buffers should not be copied into event metadata. The exact publication layer—public API wrappers or the lowest shared internal filesystem layer—can be determined during implementation, but the documented payload should remain independent of internal FSReqCallback details.

Using one operation family with an operation field avoids requiring wildcard channel subscriptions while allowing subscribers to filter individual operations.

What alternatives have you considered?

Wrapping exports from node:fs and node:fs/promises is incomplete when references have already been captured and requires synchronization with named built-in ESM exports. async_hooks exposes asynchronous resource lifecycles rather than stable filesystem operation semantics and does not cover synchronous calls. Trace events use a different consumption API and payload contract.
