fs: make `open` and `close` stream override optional when unused #40013

aduh95 · 2021-09-06T09:38:11Z

When using createReadStream or createWriteStream with a specific
file descriptor or FileHandle instead of a path, open method is not
used, there is no point in forcing users to provide it.
When using createReadStream or createWriteStream with autoClose
set to false, close method is not used, there is no point in forcing users
to provide it.

+    // When fd is a FileHandle we can listen for 'close' events
+    if (options.fs) {
+      // FileHandle is not supported with custom fs operations
+      throw new ERR_METHOD_NOT_IMPLEMENTED('FileHandle with fs');


The error message here could be more descriptive (could just use the same message as the comment)

The error message currently is The FileHandle with fs method is not implemented. ERR_METHOD_NOT_IMPLEMENTED may not be the fittest here, but I'm afraid changing it would be a breaking change, best left to another PR. Or do you have a suggestion that would work with ERR_METHOD_NOT_IMPLEMENTED?
