Function Documentation

◆ doUpgradeTVDatabaseSchema()

static bool doUpgradeTVDatabaseSchema ( void  )
static

This is called by UpgradeTVDatabaseSchema() to actually upgrade the schema to what MythTV expects.

This function Initializes the database if the "DBSchemaVer" property does not exist in the database. Otherwise it upgrades the schema from the one in that property to the currentDatabaseVersion, by running the SQL commands needed for each upgrade between the two versions. This will only upgrade the schema, so bad things may happen if you upgrade and then downgrade MythTV across DB Schema versions.

◆ UpgradeTVDatabaseSchema()

bool UpgradeTVDatabaseSchema ( const bool  upgradeAllowed,
const bool  upgradeIfNoUI,
const bool  informSystemd 
)

Called from outside dbcheck.cpp to update the schema.

If the "DBSchemaVer" property equals the currentDatabase version this returns true immediately. If not, we try to do a database backup, if interactive prompt the user for permission to do the upgrade, and if permitted or non-interactive with a successful backup do the actual update.

If the program running this function is killed while this is running then the schema may be corrupted.

Returns
false on failure, error, or if the user selected "Exit."

◆ InitializeMythSchema()

bool InitializeMythSchema ( void  )

command to get the the initial database layout from an empty database:

mysqldump \ –skip-comments –skip-opt –compact –skip-quote-names \ –create-options –ignore-table=mythconverg.schemalock mythconverg | \ sed '/^(SET|INS).*;$/d;/^\/*!40101.*$/d;s/^.*[^;]$/"&"/;s/^).*;$/"&",/'

command to get the initial data:

mysqldump \ –skip-comments –skip-opt –compact –skip-quote-names -t \ –ignore-table=mythconverg.logging mythconverg | sed -e 's/^.*$/"&",/' -e 's#\#\\#g'

don't forget to delete host specific data
