sha256
describe your issue
I have init.defaultobjectformat=sha256 configure globally to ensure I do not create any new repositories with sha1 anymore. If in a (local) sha256 repo which refers to a remote sha1 repo in its .pre-commit-config.yaml I run
pre-commit run --all-files
, I get the following error:
[INFO] Initializing environment for https://github.com/fsfe/reuse-tool.
An unexpected error has occurred: CalledProcessError: command: ('/usr/bin/git', 'fetch', 'origin', '--tags')
return code: 128
stdout: (none)
stderr:
fatal: mismatched algorithms: client sha256; server sha1
Check the log at /home/mschilli87/.cache/pre-commit/pre-commit.log
Temporarily setting
git config --global init.defaultObjectFormat sha1
enables pre-commit run to pass and successfully I can set
git config --global init.defaultObjectFormat sha256
again and it keeps working.
I guess for some reason, instead of cloning the upstream sha1 repo locally via git clone, pre-commit for some reason initiates an empty repo via git init, adds the upstream repo as origin via git remote add and the tries to fetch the specified tag via git fetch.
Anyhow, running a pre-commit hook on an existing repo based on an upstream one should not depend on config options specific to the creation of new local repos, so I consider this a bug.
