Upgrade from 1.4.2 to 2.6.0 issue

[dfranco]

Hello,

Trying to upgrade CDash from version 1.4.2 to 2.6.0 fail with the following error in log/cdash.log

cdash.ERROR: Specified key was too long; max key length is 767 bytes {"function":"pdo_error","pid":XXXX}

The system running the upgrade is Debian 9 (stretch) with PHP 7.0.33 and MariaDB 10.1

Any help would be nice

I ran into the same problem (same system) and followed this advice: http://blog.antiblau.de/tag/cdash/ which solved this for me.

More specifically, I did this before visiting install.php:

CREATE DATABASE cdash CHARACTER SET utf8 COLLATE utf8_general_ci;
