Morris Jobke d8734b3b93 Add occ preview:migrate to migrate previews from the old flat structure to a subfolder structure ... * `php occ preview:repair` - a preview migration tool that moves existing previews into the new location introduced with #19214 * moves `appdata_INSTANCEID/previews/FILEID` to `appdata_INSTANCEID/previews/0/5/8/4/c/e/5/FILEID` * migration tool can be stopped during migration via `CTRL+C` - it then finishes the current folder (with the previews of one file) and stops gracefully * if a PHP memory limit is set in the `php.ini` then it will stop automatically once it has less than 25 MiB memory left (this is to avoid hard crashes in the middle of a migration) * the tool can be used during operation - possible drawbacks: * there is the chance of a race condition that a new preview is generated in the moment the folder is already migrated away - so the old folder with the newly cached preview is deleted and one cached preview needs to be re-generated * there is the chance of a race condition during access of a preview while it is migrated to the other folder - then no preview can be shown and results in a 404 (as of now this is an accepted risk) Signed-off-by: Morris Jobke <hey@morrisjobke.de>		2020-08-06 22:05:46 +02:00
