Hi everyone,
commit cc3d52e[1] has apparently broken 'make dist' for at least some
platforms: Fedora 20 is fine[2], but both Fedora 21 and rawhide[3][4]
are currently failing. My laptop is running Fedora 22 and can make
dist just fine, which is of course very confusing.
The issue is caused by the following tar error:
tar: libvirt-1.2.18/tests/nodeinfodata/linux-deconfigured-cpus/ \
node/node0/cpu16/topology/core_siblings_list: \
link name is too long; not dumped
There seem to be basically two ways to solve the failure:
1. rename the test case, making it shorter;
2. bump tar format from ustar, which has limitations on the length
of file names, to posix/pax, which has no such limitations.
I'm not a fan of the former option because short names are usually very
opaque, see tests/nodeinfodata/linux-test[0-8] for some perfect
examples.
On the other hand, I'm not sure whether bumping the tar version would
affect portability in a significant way: the automake documentation[5]
reports that
this format is very young and should probably be restricted to
packages that target only very modern platforms
but the GNU tar documentation[6], while containing some warnings as
well, suggest that this format is going to become the default.
Any suggestions on how to proceed?
Cheers.
