For various reasons your TYPO3 installation may over time accumulate data with integrity problems or data you wish to delete completely. For instance, why keep old versions of published content? Keep that in your backup - don't load your running website with that overhead!
Or what about deleted records? Why not flush them - they also fill up your database and filesystem and most likely you can rely on your backups in case of an emergency recovery?
Also, relations between records and files inside TYPO3 may be lost over time for various reasons.
If your website runs as it should such "integrity problems" are mostly easy to automatically repair by simply removing the references pointing to a missing record or file.
However, it might also be "soft references" from eg. typolinks (<link 123>...</link>) or a file references in a TypoScript template (something.file = fileadmin/template/miss_me.jpg) which are missing. Those cannot be automatically repaired but the cleanup script incorporates warnings that will tell you about these problems if they exist and you can manually fix them.
These scripts provides solutions to these problems by offering an array of tools that can analyze your TYPO3 installation for various problems and in some cases offer fixes for them.
THERE IS ABSOLUTELY NO WARRANTY associated with this script! It is completely on your OWN RISK that you run it. It may cause accidental data loss due to software bugs or circumstances that it does not know about yet - or data loss might happen due to misuse!
ALWAYS make a complete backup of your website! That means:
Dump the complete database to an SQL file. This can usually be done from the command line like this:
mysqldump [database name] -u [database user] -p --add-drop-table > ./mywebsite.sql
Save all files in the webroot of your site. I usually do this from the command line like this:
tar czf ./mywebsite.tgz [webroot directory of your site]
It could be a good idea to run a myisamchk on your database just to make sure MySQL has everything pulled together right.
Something like this will do:
myisamchk [path_to_mysql_databases]/[database_name]/*.MYI -s -r
The "[base command]" is:
Try this first. If it all works out you should see a help-screen. Otherwise there will be instructions about what to do.
You can use the script entirely by following the help screens. However, through this document you get some idea about the best order of events since they may affect each other.
For each of the tools in the test you can see a help screen by running:
[base command] --help [toolkey]
Example with the tool "orphan_records":
[typo3_site_directory]/typo3/sysext/core/bin/typo3 --help cleanup:orphanrecords
The suggested order below assumes that you are interested in running all these tests. Maybe you are not! So you should check the description of each one and if there is any of the tests you wish not to run, just leave it out.
It kind of gets simpler that way since the complexity mostly is when you wish to run all tests successively in which case there is an optimal order that ensures you don't have to run the tests all over again.
- [base command] cleanup:orphanrecords
- As a beginning, get all orphaned records out of the system since you probably want to. Since orphan records may keep some missing relations from being detected it's a good idea to get them out immediately.
- [base command] cleanup:versions
- Flush all published versions now if you like. Published versions may also keep references to records which could affect other tests, hence do it now if you want to.
- [base command] cleanup:multiplereferencedfiles
- Fix any files referenced twice or more before you delete records (which could potentially delete a file that is referenced by another file).
- [base command] cleanup:deletedrecords
- Flush deleted records. As a rule of thumb, tools that create deleted records should be run before this one so the deleted records they create are also flushed (if you like to of course)
- [base command] cleanup:missingrelations
- Remove missing relations at this point.
- If you get an error like this; "TYPO3CMSCoreDatabaseReferenceIndex::setReferenceValue(): ERROR: No reference record with hash="132ddb399c0b15593f0d95a58159439f" was found!" just run the test again until no errors occur. The reason is that another fixed reference in the same record and field changed the reference index hash. Running the test again will find the new hash string which will then work for you.
- [base command] cleanup:flexforms
- After the "deleted" tool since we cannot clean-up deleted records and to make sure nothing unimportant is cleaned up.
These can be executed anytime, however you should wait till all deleted records and versions are flushed so you don't waste system resources on fixing deleted records.
[base command] cleanup:missingfiles [base command] cleanup:lostfiles
If you wish to scan your TYPO3 installations for problems with a cronjob or so, a shell script that outputs a report could look like this:
#!/bin/sh [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:orphanrecords -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:versions -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:multiplereferencedfiles --update-refindex -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:deletedrecords -v [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:missingrelations --update-refindex -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:flexforms -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:missingfiles --update-refindex -vv [typo3_site_directory]/typo3/sysext/core/bin/typo3 cleanup:lostfiles --update-refindex -vv
You may wish to change the verbosity level from -vv to -v as in the case above, depending on how important you consider the warnings.
You might also wish to disable tests like "deleted" which would report deleted records - something that might not warrant a warning, frankly speaking...
