I just built the updated git-2.25.0 and ran the tests. The BLFS book

running them as a normal user should produce no failures, but I

get this error:
cat: version: Permission denied
/bin/sh: GIT-BUILD-OPTIONS+: Permission denied
But if I run the tests as root, all tests pass.
I don't know if this is a problem.
Hmmm, Maybe you can try to figure out this one by yourself: first
check who is
the owner of a "version" file, or GIT-BUILD-OPTIONS file (or file
whose name
begin with version or GIT-BUILD-OPTIONS), explore your build tree,
checking
for anything that could prevent a normal user to access the files,
etc...

In the build tree, there's a file "version" with owner "110493 5000"
and permissions "-rw-r----". This is the same owner as "configure".
These are the only files not owned by "root root". If as user lfs I
"cat version" I get the same error as above -- as expected, given the
permissions for "other". If I cat some random file with owner "root
root" and permissions "-rw-rw-r-", it works fine, as expected. If, as
root, I "cat version" I get the expected "2.25.0". I don't know what
to make of this.
What does owner "110493 5000" mean? Why would only two files have this
odd ownership and why is there no read permission for "other"?
For GIT-BUILD-OPTIONS the owner is "root root" with permissions
"-rw-r--r--". I would guess that, since bash is given this file to
execute, and there is no "x" in the permissions, we get the
"permission denied" error. But if this is part of the testing, why
does whatever software that makes the build tree not add "x" to the
permissions?
And of course, since the BLFS book specifically indicates that running
the tests as a normal user is the way to go, why are the ownership and
permissions of these files not such that a normal user can run the tests?

When developing the instructions, we assume that you're building as a
normal user, and not as the root user. This is to follow the philosophy
of UNIX Administration of only using your superpowers when necessary
(see
http://linuxfromscratch.org/blfs/view/systemd/introduction/notes-on-building.html
). Seeing as you were able to get the tests to run as root though, you
should be okay. We probably have that in there from a previous release
where running the tests as root caused sporadic failures.
