Subject: sudo: git describe during GIT_VERSION_GEN not as expected..
Message-ID: <7bb71920-b840-5133-ceac-664c09942772@iee.email>

Hi,

I have run into a problem with make/install of git on my old travel 
laptop. While trying to make / install git with some patches on top of 
yesterdays next (coincidental timing) I'm finding that the generated git 
version is the default value rather than that of a regular 'get 
describe' as used in GIT_VERSION_GEN.

Commit tree state:
~/repos/git (die_preserve_2)$ git log -4 --oneline --decorate
dd96dd88c3 (HEAD -> die_preserve_2) rebase: note `preserve` merges may 
be a pull config option
53d93c1c94 rebase: help users when dying with `preserve-merges`
65721c069b rebase.c: state preserve-merges has been removed
7e84679e2a (junio/next, gitster/next, gitgitgadget/next, git/next) Merge 
branch 'cb/ci-make-p4-optional' into next

After a make/install of the above I'm getting a version string is the 
default, rather than referencing the current hash as below. I've already 
tried setting the safe.directory as advised. The second describe 
invocation is from GIT_VERSION_GEN. Note how it fails to provide the 
expected output.

~/repos/git (die_preserve_2)$ git version
git version 2.36.GIT
~/repos/git (die_preserve_2)$ git describe --match "v[0-9]*" HEAD
v2.36.1-165-gdd96dd88c3
~/repos/git (die_preserve_2)$ sudo git describe --match "v[0-9]*" HEAD
fatal: unsafe repository ('/home/philip/repos/git' is owned by someone else)
To add an exception for this directory, call:

     git config --global --add safe.directory /home/philip/repos/git
~/repos/git (die_preserve_2)$ git config --global --get safe.directory


Is this a temporary position, as the sudo safe.directory problem is 
still to be added to next? Or is it a secondary side effect of the 
install method as per [1,2]?
