Fix for MySQL 5.7+ https://github.com/friendica/friendica/issues/2786 Only tested on Ubuntu 16.10 with MySQL 5.7.17. https://dev.mysql.com/doc/refman/8.0/en/timestamp-initialization.html https://dev.mysql.com/doc/refman/8.0/en/sql-mode.html#sqlmode_no_zero_date As of MySQL 5.7.4, NO_ZERO_DATE is deprecated. Patch based on the following search & replace (and then reverting some changes in libraries): ```sh grep -l '= "0000-00-00"' -r . | xargs sed -i -e "s/= \"0000-00-00\"/= '0000-00-00'/g" grep -l "0000-00-00" -r . | xargs sed -i -e "s/0000-00-00/0001-01-01/g" grep -l "!= '0001-01-01'" -r . | xargs sed -i -e "s/!= '0001-01-01'/> '0001-01-01'/g" grep -l " === '0001-01-01'" -r . | xargs sed -i -e "s/ === '0001-01-01'/ <= '0001-01-01'/g" grep -l " == '0001-01-01'" -r . | xargs sed -i -e "s/ == '0001-01-01'/ <= '0001-01-01'/g" grep -l "strpos(\$dob, '0000-') === 0" -r . | xargs sed -i -e "s/strpos(\$dob, '0000-') === 0/strpos(\$dob, '0000-') === 0 || strpos(\$dob, '0001-') === 0/g" grep -l 'array("", "0001-01-01")' -r . | xargs sed -i -e 's/array("", "0001-01-01")/array("", "0000-00-00", "0001-01-01")/g' grep -l "\$dob = '0000-'" -r . | xargs sed -i -e "s/\$dob = '0000-'/\$dob = '0001-'/g" ```
