This maybe an issue of xorm. |

Is there anything I should do about this manually? |

Provides new command: `gitea doctor recreate-table` which will recreate db tables and copy the old data in to the new table. This function can be used to remove the old warning of struct defaults being out of date. Fix go-gitea#8868 Fix go-gitea#3265 Fix go-gitea#8894 Signed-off-by: Andrew Thornton <art27@cantab.net>

OK at least part of this is a bug of xorm. The issue is: func (session *Session) Sync2(beans ...interface{}) error {...}Calls: func (db *mysql) CreateTableSQL(table *schemas.Table, tableName string) ([]string, bool) {...}Which calls func ColumnString(dialect Dialect, col *schemas.Column, includePrimaryKey bool) (string, error) {...}which at: if col.Default != "" {
if _, err := bd.WriteString("DEFAULT "); err != nil {
return "", err
}
if _, err := bd.WriteString(col.Default); err != nil {
return "", err
}
if err := bd.WriteByte(' '); err != nil {
return "", err
}
}skips out the Default if it's empty. However this conflicts with later parts of Sync2, in particular: if col.Default != oriCol.Default {
switch {
case col.IsAutoIncrement: // For autoincrement column, don't check default
case (col.SQLType.Name == schemas.Bool || col.SQLType.Name == schemas.Boolean) &&
((strings.EqualFold(col.Default, "true") && oriCol.Default == "1") ||
(strings.EqualFold(col.Default, "false") && oriCol.Default == "0")):
default:
engine.logger.Warnf("Table %s Column %s db default is %s, struct default is %s",
tbName, col.Name, oriCol.Default, col.Default)
}
}Where func (db *mysql) GetColumns(queryer core.Queryer, ctx context.Context, tableName string) ([]string, map[string]*schemas.Column, error) {
args := []interface{}{db.uri.DBName, tableName}
s := "SELECT `COLUMN_NAME`, `IS_NULLABLE`, `COLUMN_DEFAULT`, `COLUMN_TYPE`," +
" `COLUMN_KEY`, `EXTRA`,`COLUMN_COMMENT` FROM `INFORMATION_SCHEMA`.`COLUMNS` WHERE `TABLE_SCHEMA` = ? AND `TABLE_NAME` = ?" +
" ORDER BY `INFORMATION_SCHEMA`.`COLUMNS`.ORDINAL_POSITION"
rows, err := queryer.QueryContext(ctx, s, args...)
if err != nil {
return nil, nil, err
}
defer rows.Close()
cols := make(map[string]*schemas.Column)
colSeq := make([]string, 0)
for rows.Next() {
col := new(schemas.Column)
col.Indexes = make(map[string]int)
var columnName, isNullable, colType, colKey, extra, comment string
var colDefault *string
err = rows.Scan(&columnName, &isNullable, &colDefault, &colType, &colKey, &extra, &comment)
if err != nil {
return nil, nil, err
}
col.Name = strings.Trim(columnName, "` ")
col.Comment = comment
if "YES" == isNullable {
col.Nullable = true
}
if colDefault != nil {
col.Default = *colDefault
col.DefaultIsEmpty = false
} else {
col.DefaultIsEmpty = true
}
