Make sure that it is safe to call the callback for `_write()` even in the presence of `.destroy()` calls during that write. In particular, letting the write queue continue processing would previously have thrown an exception, because processing writes after calling `.destroy()` is forbidden. One test had to be modified to account for the fact that callbacks for writes will now always be called, even when the stream is destroyed during the process.

Huh, apparently the test change was only necessary for an earlier version of this patch… interesting. I’m not sure I like this behavior, but on the other hand it means that this is more likely to pass as semver-patch? New CI: https://ci.nodejs.org/job/node-test-pull-request/18319/ (:heavy_check_mark:) |

@nodejs/streams @mcollina @mafintosh I’m mostly looking for feedback on the idea here rather than the implementation, i.e., does this make sense, is this the right behaviour, etc.?
Also, does the test modification here mean that we might have to consider this a breaking change rather than a bugfix?Make sure that it is safe to call the callback for
_write()even in the presence of
.destroy()calls during that write.In particular, letting the write queue continue processing would
previously have thrown an exception, because processing writes
after calling
.destroy()is forbidden.One test had to be modified to account for the fact that callbacksfor writes will now always be called, even when the stream
is destroyed during the process.
