When working on test cases for #827 and #734 the following issues occurred 1. There was no support to pass in `Data` for `stdin` (input pipe added + new argument for the data) 2. Pipes were getting blocked during the `try process.run()` and `process.waitUntilExit()` (order of operations were fixed) 3. We need the binary data for directly piping the `stdout` data to `stdin`, and converting the data to a `string`, returns `""` (added a new value to the tuple) I opened a new PR here for this as I did not want to bloat the other PRs with so many updates. At first I thought of creating a new function named `runStdinStdout`, but that seemed redundant as it pretty much was going to do the same thing as `run`. ## Testing - [x] Tested locally - [x] Added/updated tests - [ ] Added/updated docs --------- Co-authored-by: J Logan <john_logan@apple.com>

@saehejkang Just merged the underlying test change, could you resolve conflicts on this? I'll have a look after and then try building it and doing a little local testing. Thanks! |

There was a problem hiding this comment.
Looks good, wanted to see what your thought about making the conditionals for the stdio cases a little more straightforward. And thanks for adding the tests, that capability will likely be handy elsewhere.
