- // Why run rustdoc in a separate task? That's a good question!
- //
- // We first begin our adventure at the ancient commit of e7c4fb69. In this
- // commit it was discovered that the stack limit frobbing on windows ended
- // up causing some syscalls to fail. This was worked around manually in the
- // relevant location.
- //
- // Our journey now continues with #13259 where it was discovered that this
- // stack limit frobbing has the ability to affect nearly any syscall. Note
- // that the key idea here is that there is currently no knowledge as to why
- // this is happening or how to preserve it, fun times!
- //
- // Now we continue along to #16275 where it was discovered that --test on
- // windows didn't work at all! Yet curiously rustdoc worked without --test.
- // The exact reason that #16275 cropped up is that during the expansion
- // phase the compiler attempted to open libstd to read out its macros. This
- // invoked the LLVMRustOpenArchive shim which in turned went to LLVM to go
- // open a file and read it. Lo and behold this function returned an error!
- // It was then discovered that when the same fix mentioned in #13259 was
- // applied, the error went away. The plot thickens!
- //
- // Remember that rustdoc works without --test, which raises the question of
- // how because the --test and non --test paths are almost identical. The
- // first thing both paths do is parse and expand a crate! It turns out that
- // the difference is that --test runs on the *main task* while the normal
- // path runs in subtask. It turns out that running --test in a sub task also
- // fixes the problem!
- //
- // So, in summary, it is unknown why this is necessary, what it is
- // preventing, or what the actual bug is. In the meantime, this allows
- // --test to work on windows, which seems good, right? Fun times.
