Subject: Re: F30 Self-Contained Change proposal: Bash 5.0
It's not the "only" issue, because it was submitted over two weeks
*after* the deadline for system-wide changes.
I am somewhat concerned about dropping in a major new bash version
quite late in the cycle and just before the mass rebuild, particularly
when there are bits like this in the announcement:
"There are a number of changes to the
expansion of $@ and $* in various contexts where word splitting is not
performed to conform to a Posix standard interpretation, and additional
changes to resolve corner cases for Posix conformance." (are you *sure*
all our corner cases are expecting Posix-conformant behaviour? I'm not)
"The `globasciiranges' shell option
is now enabled by default; it can be set to off by default at
configuration time." (OK, so we can turn it off again if necessary, but
still, could be interesting)
"There are a few incompatible changes between bash-4.4 and bash-5.0"
(sure, these are in 'rarely used' things, but we have an awful *lot* of
shell scripts in us. We're a Linux distribution, it comes with the
territory. I'm pretty sure we use those 'rarely used' thing at least
somewhere)
that *plus* the required readline version bump *plus* the suggestion
that some significant bugs were already discovered in the .0 release
makes me a little hesitant about this. I'm not saying "no!", but...it
certainly strikes me as a potentially disruptive change that needs some
kind of justification to go in late beyond "NEW SHINY".
I agree that it would be much safer to target it for Fedora 31. I have no objection if we
change target release.
