[Maria-developers] ALTER TABLE xxx ENGINE=aria, progress only works in copying stage

hi guy, i was changing myisam to aria on some big tables (15gb) and show processlist stop reset the progress at 16% the operation started with 'copying to tmp table', and i saw 1%, 2% ... 16% now the table is doing "repair by sorting" and progress is 0% the point is... could the processlist show, at least, the last progress percentage? without get back to 0%? or maybe a column of current operation progress and another of total process operation? does 'repair by sorting' have progress algoritm implemented? i'm running mariadb 10.0.1 on linux 64bits thanks guys -- Roberto Spadim
