Good report thanks!

mgmt version 0.0.19-21-ga050cff-dirty

Can you reproduce this with a clean version please. Dirty means there's some weird junk in there, which means it's very hard for me to know exactly what line in the trace corresponds to what :(

May 14 '19 13:05 purpleidea

only patch is #517 which is required to reproduce

Tentative fix in: https://github.com/purpleidea/mgmt/commit/812fd57c33b7a6d1d432bc5bbea8ea679b13ce96

Thanks for finding this =D

I wasn't able to reproduce this, but I did get a deadlock I think...

I also tried to speed things up with this variant:

# prepare with:
# sudo mkdir -p /tmp/tmpfs/
# sudo mount -t tmpfs -o size=1m tmpfs /mnt/tmpfs
# echo foo > /tmp/tmpfs/test

import "os"
import "strings"

$str = strings.trim_space(os.readfile("/mnt/tmpfs/test"))

file "/mnt/tmpfs/test" {
	content => if $str == "2" { "1" } else { "2" },
}

Not sure if it helps, but maybe.
