People expect to use this (the docs even almost even suggested it at some point), so it is better to make it work as expected (and better than they can emulate) than to criticize their choices. Also fix a few regressions and handling mistakes in setup_stdios: - #44500 tried to store a Redirectable into a SpawnIO, dropping FileRedirect - CmdRedirect did not allocate a ProcessChain, so it wouldd call setup_stdio then call setup_stdios on the result of that, which is strongly discouraged as setup_stdio(s) should only be called once - BufferStream was missing `check_open` calls before writing, and ignored `Base.reseteof` as a possible means of resuming writing after `closewrite` sends a shutdown message. Currently this fix is disabled because Pkg seems like a bit of a disaster with IO mismanagement. - Add `closewrite` to more methods, and document it. Fixes #39311 Fixes #49234 Closes #49233 Closes #46768

This should avoid the test bug introduced by #52217 (this bug was noticed also in the CI run before merging #52217 (comment) but ignored there) that caused this recent CI run to fail: https://buildkite.com/julialang/julia-master/builds/31117#018c5b9f-5171-48a7-95a8-186282ca9fef |

| * New function `Docs.hasdoc(module, symbol)` tells whether a name has a docstring ([#52139]). | ||
| * Passing an IOBuffer as a stdout argument for Process spawn now works as | ||
| expected, synchronized with `wait` or `success`, so a `Base.BufferStream` is | ||
| no longer required there for correctness to avoid data-races ([#TBD]). |

There was a problem hiding this comment.
Whoops — "TBD" should have been updated.
