Configuring Git to Send Commit Notices
To allow others to see what you are working on in your MariaDB tree, you should:
Download the post-commit git trigger script. Configure as
git config --global hooks.postcommitrecipients "email@example.com" git config --global hooks.postcommitbranches "*"
Also you might want to check the README for the post-commit trigger.
The post-commit git trigger uses sendmail for sending emails. Some platforms don't have sendmail and then you'll need to modify to make use of something that is supported.
Also, the post-commit trigger is just one approach. You can also use git-email on at least Debian and Fedora to send commit emails to the MariaDB commits email list.
