Subject: [PATCH 1/3] use FFI call to rpmvercmp function for
version
comparison
Stop using rpm-python to compare package versions since the
implicit NSS
initialization upon the module import breaks NSS handling in
IPA
code. Call
rpm-libs C-API function via CFFI instead.
Big thanks to Martin Kosek <mko...@redhat.com> for sharing the
code
snippet
that spurred this patch.

It's not very common to depend on devel packages.
LS
I was basically trying workaround this
http://fpaste.org/308652/22677521/
rpm-libs contains librpm.so.*
and cffi is smart enough to load right library with
C = ffi.dlopen("rpm")
This likely won't be an issue here, but in general, we should use
the
versioned library name to have at least some API/ABI guarantee.
If for
example a function we depend on changed signature between
versions, we
would crash *hard* when it's called.
So it's enough to add "Requires: rpm-libs"
but it would be almost noop because rpm-libs is everytime
available
od fedora/rhel :-)
"Requires: rpm-devel"
add unnecessary additional runtime dependencies on pkgconfig,
popt-devel
librpm.so.7 belongs to rpm-libs and librpm.so to rpm-devel and
I was
lazy
(hey it's friday) to add path to librpm.so.7 to paths and use it
i LD
loader.
If you think that it is not optimal I will fix it, but let's
wait
for
some
more feedback.
Sure wait for another python related comments.
NACK. The ffi.cdef() and ffi.dlopen() should be in the module
scope,
and
the ffi.new() calls are unnecessary.
Attaching updated patches. I have added specific versions of librpm
shared lib to platform specific namespaces. Both of them were
tested
and
work.
You haven't tested on any 32 bit architecture, have you? I'm sure
/lib64
will not work there.
Note that when you dlopen just "librpm.so.$N", the correct path
according to dynamic linker configuration will be used.
I have also change dependency to rpm-libs.
Given librpm is dlopened by full path, I think we should depend
directly
on the "librpm.so.$N()" soname rather than rpm-libs.
Updated patches attached.
Attaching another version.

Did you mean:
raise TypeError(
"Unexpected comparison string: {}".format(expected_comparison))
?
Sorry I temporarily forgot how to python over there. Attaching updated
patch.
Works for me, but shouldn't be the file named test_version_compaRISOn.py
instead of test_version_compaRSIOn.py?
Seems like I forgot how to english as well. Attaching updated patch.
