Additional flags in scriptlets (like `%pre -f`) about python-rpm-macros

[bnavigator]

I checked out home:crameleon:LibertaCasa/python-limnoria and built it locally:

[  249s] error: Could not open Prein file /home/abuild/rpmbuild/BUILD/home/abuild/rpmbuild/SOURCES/Limnoria-20220814/limnoria.pre: No such file or directory

Note the wrong path .../BUILD/home...

But I agree that %pre -f %{appname}.pre not working with %setup -n %{_sourcedir}/%{appdir} -D -T is not related to python-rpm-macros. The python-rpm-macros bug about not correctly copying %pre -f %{appname}.pre should be fixed by the updated #142 now.

[tacerus]

For now, I am working around the issue by dumping the contents of the sysusers script and inserting it manually into my spec file, without the -f:

%pre
/usr/sbin/sysusers2shadow system-user-limnoria.conf <<"EOF" || [ -f /.buildenv ]
u limnoria - "Limnoria IRC Bot" /var/lib/empty -
EOF

[bnavigator]

What do you mean by "additional"? There is always only one %pre scriptlet per package, which will be copied over to the flavor subpackages using the -n pkgname flag. I cannot find any documentation on the -f flag for scriptlets. I am assuming it works the same way as %files -f <file>.

It looks like there is a - instead of a whitespace before the -f flag. You may have found a bug in python-rpm-macros. Do you have an example specfile, where this can be investigated?

[tacerus]

Hi,

sorry for the confusion. I'm not sure about upstream documentation about -f, but our sysuser macros package demands on using it, and this is what we document in the Wiki as well: https://en.opensuse.org/openSUSE:Packaging_guidelines#Users_and_Groups.

The whitespace was just an attempt on circumventing the error - it did not change the result.

Here is an example spec file which currently has the dumped sysuser script in its %pre section (as the -f route resulted in the "Too many names" error):
https://build.opensuse.org/package/view_file/home:crameleon:LibertaCasa/python-limnoria/python-limnoria.spec?expand=1

[bnavigator]

Thanks for the report. Indeed we do not allow extra parameters in copied section headers except for -f in %files

I have drafted a fix in #142.
https://build.opensuse.org/package/show/home:bnavigator:python-rpm-macros/python-limnoria gets past the initial error and only fails in the test suite afterwards just as with your work around.

You will have to keep the workaround until #142 lands in python-rpm-macros for Factory.

[tacerus]

Thank you so much for this, that's very promising! It's not urgent for me. :-)

[bnavigator]

Something is still wrong:

https://build.opensuse.org/package/show/home:bnavigator:python-rpm-macros/python-limnoria indefinitely hangs for me here:

Oh, and #138 does not allow newlines in the argument for %python_install_alternatives. :(

After fixing #138, the hang disappears, but rpm -q --scripts does not show any content for preinstall?

Weird, I branched your home:bnavigator:python-rpm-macros and %pre -f works fine with it - you can debug it by putting cat %{appname}.pre into the %check section. I committed my working copy here if you want to check, but it's still blocked, so might take a while til it starts building: https://build.opensuse.org/package/show/home:crameleon:LibertaCasa/python-limnoria.

[tacerus]

does not allow newlines in the argument for %python_install_alternatives.

That's interesting - I actually never modified this section, I forked this package from devel:languages:python and added some bits, but left the alternatives as they are - never had any issues with it, it builds and installs fine - maybe I should verify the alternatives after installing the package on a system?

The package in home:bnavigator:python-rpm-macros/python-limnoria is a branch of yours I did the exactly same locally before you wrote.

It's a still open PR and part of the python-rpm-macros of the testing project. I have already fixed it and that's why yoru limnoria sucessfully builds.

I am just a bit confused that rpm -q --scripts shows that there is a preinstall scriptlet using /bin/sh but does not show the content of the limnoria.pre file.

[tacerus]

I'm not exactly sure how rpm -q --scripts works - but the script seems to work. Since the rpm output says the pre-install script is /bin/sh, not like the Python alternatives script where it says it is using /bin/sh, I think it may just be the format of what the sysusers macro generates making rpm --scripts parse it differently.

[bnavigator]

That's an evil way to hide scriptlet content from users then, isn't it?

[tacerus]

Hah.. :-) I found the source code for it, but can't really make sense of it:

https://github.com/rpm-software-management/rpm/blob/2a8d89a1c390e6ca1de0ece49aa11012b1d0ff89/rpmpopt.in#L15

When I look at other packages using ths %pre -f name.pre syntax, their output is okay however:

avahi.spec:

preinstall scriptlet (using /bin/sh):

My bad. The LUA pattern was wrong:

python-rpm-macros/macros.lua

Line 228 in 2a68d52

subpkg, append = param:match("^([^-]%S*)%s*(.*)$")

it should read

python-rpm-macros/macros.lua

Line 227 in a038e73

subpkg, append = param:match("^([^-%s]*)%s*(.*)$")

[bnavigator]

Now that the python_subpackages rewriter works as intended, the "could not open prein file in ...SOURCES" error (#141 (comment)) is back. When I add tar and ?recompress to _service instead of hacking SOURCES to be BUILD, everything is fine.

Interesting findings - but I'm not sure they are related to python-rpm-macros - with your patched version of the macros my spec file is building fine - maybe something else is different in your project?
I can't quite explain why rpm would care about the SOURCES/BUILD structure to determine its scripts though - I think this is either an upstream bug or some poorly documented behavior of rpm. Maybe it tries to store the scripts in some specific directory structure? I'll have to try and understand the rpm internal logic for this.

It is not building fine. The original patch did not install the pre script at all. Check the output near the end when rpm runs some final checks (#141 (comment)). You will notice complaints about not having the correct user.
