[HEADS UP] Rebasing to Readline-8.0 in rawhide

[Siteshwar Vashisht]

Readline-8.0 was released earlier this month[1]. I am going to rebase it in rawhide in couple of weeks.

Note that a couple of things break in weird ways every time readline gets a new
major version.  For me that's the command line editing functionality of
the kerberos tools like kadmin.  The root cause of this is something
called "libss" which is part of e2fsprogs (!).  It tries to abstract
readline functionality and has a hardcoded list of libraries that it
looks for:

get_readline.c:#define DEFAULT_LIBPATH "libreadline.so.7:libreadline.so.6:libreadline.so.5:libreadline.so.4:libreadline.so:libedit.so.2:libedit.so:libeditline.so.0:libeditline.so"

Could you work with the e2fsprogs maintainer to make sure that libss
continues to work as expected?

Thanks,

I would do that. I will also provide a compatibility package for readline 7.

Thanks.

SV> I will also provide a compatibility package for readline 7.

That does help, but then you have to know that it's the magic package
you need to install in order to restore the command line editing
capability.  Nothing about the libss setup makes that obvious, since it
only tries to load a list of libraries by name at runtime and doesn't
link against them at all.  There's no packaging dependency between it
and any of the various libraries it will use.
