Re: [Rpm-maint] [rpm-software-management/rpm] RFE: add an override to allow installing content flagged "untrusted" (Issue #2630)

2023-08-23 Thread Brian J. Murrell
As for an impact statement on this ticket, currently we are stuck at using 
Fedora 37 as our mock host, since Fedora 38 introduced this new behaviour and 
does not work with packages from SUSE (at a minimum).

Using Fedora 37 as a mock host of course has an expiry date -- when it becomes 
EOL and unsupported any more.  The hope is by that time, this is resolved and 
we can once again use the latest Fedora.

Re: [Rpm-maint] [rpm-software-management/rpm] Obsoleted-by: would be useful in some cases (#1768)

No.  That is not the problem.  The problem is that in order to support both 
RHEL 8.4 and RHEL 8.3, while building on RHEL 8.4 (because one should not build 
one's software on unsupported older releases of the distro) I have to supply a 
backport of a newer version of a library for RHEL 8.3 installations due to that 
library breaking it's ABI on RHEL 8.4.  But the package that that library 
backport is in needs to be cleanly replaced by the distro's package when that 
node is upgraded to RHEL 8.4.

So to be clear, my package foo-1.0 requires hwloc-2.x on RHEL 8.4.  But RHEL 
8.3 doesn't supply hwloc-2.x but rather hwloc-1.x (notice the SO major version 
is not appended to the name like, say, SUSE does).  So along with foo-1.0, I 
need to supply hwloc2-2.x that gets installed with my foo-1.0 when being 
installed on a RHEL 8.3 system.  Since RHEL 8.4 supplies hwloc-2.x, only 
foo-1.0 gets installed on it.

Now when a RHEL 8.3 system that my foo-1.0 and hwloc2-2.x is installed on is 
upgraded to RHEL 8.4, my supplied hwloc2 should be upgraded to the distro 
supplied hwloc-2.x.

My being able to build hwloc2 with an _Obsoleted-by: hwloc > 1_ would achieve 
this.

And this is the problem.  I am not the distro vendor.  I am a third-party 
software supplier.  I cannot influence how the distro packages and can only 
influence how **I** package but am missing the tools (_Obsoleted-by: hwloc > 
1_) needed to seemlessly integrate with the distro.  I am also not going to get 
the distro vendor to support that older release by supplying a backport for it, 
so I have to do that myself.  But I need to be able to do it in such a manner 
that it integrates with the distro seemlessly.

IMHO, RPM needs to not only support the distro vendor but needs to provide the 
tools necessary for third-parties (i.e. non-distros) to integrate into the 
distro.

You end up having to invoke forty-eleven other tools (awk, sed, grep, tr, etc.) 
to do what bash can do.  :-(

Re: [Rpm-maint] [rpm-software-management/rpm] Define shell to use with %() (#1334)

2020-08-19 Thread Brian J. Murrell
Fair enough on being able to invoke various interpreters.  I don't have enough 
interest to lobby for that.

But being able to define the posix shell that `%()` uses would be useful and 
make for more portable specfiles.

Re: [Rpm-maint] [rpm-software-management/rpm] Define shell to use with %() (#1334)

2020-08-18 Thread Brian J. Murrell
@voxik I can't see why Ruby (or python, or awk, or any other interpreter) would 
not work.  As for _supported_, that's not my call.

But as you point out, this does allow the spec writer more flexibility in what 
interpreter their spec evaluates macros, but does require them to define the 
shell in their spec to get something other than the default `/bin/sh`.

This is not unlike [setting SHELL in 
Makefiles](https://www.gnu.org/software/make/manual/html_node/Choosing-the-Shell.html).

[Rpm-maint] [rpm-software-management/rpm] Define shell to use with $() (#1334)

2020-08-18 Thread Brian J. Murrell
It would be nice to be able to define which shell should be used with `%()` 
given that `/bin/sh` is not the same shell on all distros.  Additionally having 
to write `$()` macros to the lowest common denominator is just ugly.  It's much 
nicer to just make _bash_ a `BuildRequires:` and be able to write bashisms 
in`%$()`.  Particularly given that most(?) distros do use bash for `/bin/sh` 
and only a few outliers don't.
