< CDash Main Page

This page explains how to upgrade CDash. CDash upgrade mechanism allows users to upgrade CDash at any point in time, even if they are using the current SVN development of CDash.

Upgrading CDash

  1. It is recommended that you backup the CDash database.
  2. Backup your configuration file: CDash/config.php
  3. Replace your current CDash directory with the latest version. An in place "svn upgrade" may not be sufficient.
  4. Restore the configuration parameters: the config.php file may change from one revision to the other, make sure you are not replacing the config.php file but are actually replacing the parameters inside the file.
  5. Navigate your browser to your CDash page. (eg. http://localhost/CDash)
    1. Note the version number on the main page. It should correctly match the new version that you are upgrading to.
    2. The following message may appear: "The current database shema doesn't match the version of CDash you are running, upgrade your database structure in the Administration panel of CDash." This is a helpful reminder to perform the following steps:
  6. Login to CDash as administrator.
  7. In the ‘Administration’ section, click on ‘[CDash Maintenance]’
  8. Click on ‘Upgrade CDash’: This process might take some time depending on the size of your database, do not close your browser.
    1. Progress messages may appear while CDash performs the upgrade.
    2. If the upgrade process takes too long you can check in the backup/cdash.log file to see where the process is taking a long time and/or failing.
    3. It has been reporting that on some systems the spinning icon never turns into a checkmark. Please check the cdash.log for the "Upgrade done." string if you feel that the upgrade takes too long.
    4. CDash 1.6: new indexes and fields for the database have been added. The indexes and fields touch the test table and might take a long time to upgrade, just be patient and check the backup/cdash.log file to see the current progress of the update. On a 80GB database the upgrade took about 4 hours.
  9. Note: Some web browsers are having issue when upgrading (some javascript variables not passed correctly), in that case you can perform individual updates:

Backing up CDash

CDash stores all the information (except logs) in the database, so it's important to backup your database before any CDash upgrade.


There are a couple a ways to backup a MySQL database. The easiest way is to use the mysqldump command.

Example to backup the cdash database:

 mysqldump -r cdashbackup.sql cdash

If you are using exclusively MyISAM tables you can copy the CDash directory in your MySQL data directory. Note that you need to shutdown the MySQL before doing the copy since, no file can be touched during the copy.


Similarly to MySQL, PostGreSQL has a pg_dump utility.

Example to backup the cdash database:

 pg_dump -U postgreSQLuser cdash > cdashbackup.sql
