Thanks for the report. Those two options work for filename completion, but not command completion (the bulk of which is handled outside readline). I'll take a look at exposing that functionality outside readline, since it's currently part of readline's filename completion, but that will take some time and probably require a version bump. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRUc...@case.eduhttp://tiswww.cwru.edu/~chet/

Interesting. I haven't seen this one either. The issue is around pipesize.h which in 5.1 can be built by two different triggers, builtins/ulimit.o or redir.o. They can race against each other and rewrite files causing the above failure. I suppose that workaround will do, since it should only be built one time, no matter how many times you run make. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRUc...@case.eduhttp://tiswww.cwru.edu/~chet/
Parallel make race in 5.1
Hi,
In bash 5.1 we're seeing a parallel make race during build, as found a
couple of times in our automated CI for Yocto Project:
https://autobuilder.yoctoproject.org/typhoon/#/builders/80/builds/1720/steps/14/logs/stdio
https://autobuilder.yoctoproject.org/typhoon/#/builders/44/builds/2969/steps/25/logs/stdio
The issue is around pipesize.h which in 5.1 can be built by two
different triggers, builtins/ulimit.o or redir.o.
They can race against each other and rewrite files causing the above
failure.
We added a bit of a hacky workaround:

nameref to array[@] doesn't always expand to multiple words
See:
$ a=(1 2 3)
$ b=a[@]
$ declare -n c=a[@]
$
$ printf '<%s>\n' "${!b}"
<1>
<2>
<3>
$ printf '<%s>\n' "$c"
<1 2 3>
$ printf '<%s>\n' "${!b}$c"
<1>
<2>
<31>
<2>
<3>
This is reproducible on devel too.
