I just noticed that my buildfarm animal longfin has been stuck for
the past 24 hours in t/001_initdb.pl, and I can replicate that
in a manual build. ktrace says it's in some sort of loop.
Apparently, macOS has got IO::Pty but it doesn't actually work
the way this patch expects. Therefore, the proposed patch will
leave things still broken for macOS :-(
I tried this:
diff --git a/src/test/perl/TestLib.pm b/src/test/perl/TestLib.pm
index 18b4ce35c2..d67ffc4368 100644
--- a/src/test/perl/TestLib.pm
+++ b/src/test/perl/TestLib.pm
@@ -192,8 +192,7 @@ INIT
}
else
{
- use charnames ':full';
- @no_stdin = ('<pty<', \"\N{END OF TRANSMISSION}");
+ @no_stdin = ('<pty<', \"");
}
}
and that seems to fix it. I wonder what's the point of sending
a nonempty string to the pty, exactly?
regards, tom lane
