aur sync -c does not work

[nl6720]

After upgrading from aurutils 19-1 to aurutils 19.2-1, aur sync -c doesn't work anymore. No output is produced at all.

See attached logs of:

$ AUR_DEBUG=1 aur sync -c aurutils

aurutils-19.2-1-bad.log
aurutils-19-1-good.log

I'm also can reproduce this issue with aur sync -cu. My mitigation right now is downgrading aurutils version 19.2 to 19.1 and add IgnorePkg=aurutils to /etc/pacman.conf to pin aurutils version.

I'm also attaching debug logs for comparison:
aurutils-19.1.log
aurutils-19.2-fail.log

It makes no sense to me that it would work in 19.1, but not 19.2. The only thing that changed is 6f91817

Does reverting that commit fix the issue?

6f91817 is bork while eb664e7 works fine.

Fixed in 19.3

Cleared the mystery: type -P prints the command name to standard output, and this resulted in aur chroot --status printing six lines instead of the (expected) three. This in turn leads to a SIGPIPE in wait $!: https://github.com/aurutils/aurutils/blob/master/lib/aur-build#L226

Using hash or command -p as suggested on IRC would help, or just redirect standard output to /dev/null. That said, I think adding these diagnostics - when the required commands can easily be retrieved from say, pacman -F - was premature anyway.

I've added an additional error message to avoid future confusion: db906f3
