[ATN] ovirt-engine dbscritps cleanup (master)

[Alon Bar-Lev]

Hello All,

The dbscripts of ovirt-engine master were cleaned up, to match other scripts in tree.

Developer visible changes are:

1. Removal of create_schema.sh, upgrade.sh, cleandb.sh, refreshStoredProcedures.sh in favour of single schema.sh script, note the -c parameter.

Usage: ./schema.sh [options]

    -h            - This help text.
    -v            - Turn on verbosity                         (WARNING: lots of output)
    -l LOGFILE    - The logfile for capturing output          (def. )
    -s HOST       - The database servername for the database  (def. localhost)
    -p PORT       - The database port for the database        (def. 5432)
    -u USER       - The username for the database             (def. engine)
    -d DATABASE   - The database name                         (def. engine)
    -m MD5FILE    - Where to store schema MD5 files           (def. )
    -c COMMAND    - Command: apply|refresh|drop
    -t            - Force cleaning tasks and compensation info.

2. Introduction of schema-dev.sh as a wrapper to schema.sh with defaults as a utility for developers.

- always enable md5.
- always enable logging.
- apply command as default.

3. Shell upgrade script is not receives entire settings via DBFUNC_* environment variables.
