Git Commit Hook Alternative

[AlJohri]

I just wanted to post a quick alternative to git-auto using a git post-commit hook and some gotchas I ran into while getting this set up. I like this approach because it ensures every commit is immediately pushed.

Creating post-commit hook

1. Ensure your logseq database is a git repository. This usually entails running git init in the root of the logseq directory.
2. Check "Enable Git auto commit" in the Logseq version control settings.
3. Create the file .git/hooks/post-commit relative to the root of the logseq repository with the following contents:

   #!/bin/bash
   git push
   

Potential Gotchas

1. On macOS, I usually use the osxkeychain for authentication using a "personal access token". This, for some reason didn't work out well and kept giving me the following error: fatal: could not read Username for 'https://github.com': Device not configured. I ensured that the script was being run as personal account, not root, but this didn't fix the issue. The easiest solution was to switch to using the git-credential-manager (GCM).

   # check if current credential.helper is osxkeychain
   ❯ git config credential.helper
   osxkeychain
   
   # clear osxkeychain password
   ❯ git credential-osxkeychain erase
   host=github.com
   protocol=https
   > [Press Return]
   
   # install latest git and git credential manager (GCM) from homebrew
   ❯ brew install git
   ❯ brew tap microsoft/git
   ❯ brew install --cask git-credential-manager-core
   
   # verify cask installation has automatically updated the credential.helper
   ❯ git config credential.helper
   /usr/local/share/gcm-core/git-credential-manager-core
   
   # attempt to git push, will bring up a pop-up establishing authentication
   git push
   

2. For some reason, I was unable to change the hashbang for the post-commit hook. It seems to always use the system bash installed at /bin/bash (for me, version 3.2.57) even if I explicitly changed the hashbang to homebrew installed bash via #!/opt/homebrew/bin/bash. This means you can't use newer bash features like mycmd &>> /tmp/mylog etc.

   This longer script helped me debug all of these issues:

   #!/bin/bash
   mkdir -p /tmp/logseq/
   timestamp=$(date +"%s")
   filepath="/tmp/logseq/$timestamp"
   touch $filepath
   echo "attepmting push" >> $filepath
   echo "current directory: $(pwd)" >> $filepath
   echo "bash version: $(bash --version)" >> $filepath
   echo "whoami: $(whoami)" >> $filepath
   git remote -v >> $filepath 2>&1
   git push >> $filepath 2>&1
   

Hope this helps!

Nice alternative. I was having issues getting git-auto to work on Windows. For those on windows the contents of .git/hooks/post-commit should be

#!/bin/sh
git push
