LDAP User Cleanup

background job for user clean up

adjust user backend for clean up

register background job

remove dead code

dependency injection

make Helper non-static for proper testing

check whether it is OK to run clean up job. Do not forget to pass arguments.

use correct method to get the config from server

methods can be private, proper indirect testing is given

no automatic user deletion

make limit readable for test purposes

make method less complex

add first tests

let preferences accept limit and offset for getUsersForValue

DI via constructor does not work for background jobs

after detecting, now we have retrieving deleted users and their details

we need this method to be public for now

finalize export method, add missing getter

clean up namespaces and get rid of unnecessary files

helper is not static anymore

cleanup according to scrutinizer

add cli tool to show deleted users

uses are necessary after recent namespace change

also remove user from mappings table on deletion

add occ command to delete users

fix use statement

improve output

big fixes / improvements

PHP doc

return true in userExists early for cleaning up deleted users

bump version

control state and interval with one config.php setting, now ldapUserCleanupInterval. 0 will disable it. enabled by default.

improve doc

rename cli method to be consistent with  others

introduce ldapUserCleanupInterval in sample config

don't show last login as unix epoche start when no  login happend

less log output

consistent namespace for OfflineUser

rename GarbageCollector to DeletedUsersIndex and move it to user subdir

fix unit tests

add tests for deleteUser

more test adjustements

forgotten file

PHPdoc fixes, no code change

and don't forget to adjust tests

remove unused methods

split mapping methods off from Access class

fix DB query handling

move 'clear mapping' methods from static helper to new mapping class

add tests

test directly with DB

finishing tests and fix return value from setDNbyUUID

add corresponding class for groups and make abstract test class neutral. helper tests is now obsolete as the tested functions were moved to the new mapper class.

add missing info to PHPDoc

add unmap method

fix namespaces

fix test inheritance

PHPDoc and a small code restructure for scrutinizer, no effective changes

PostgreSQL does not accept LIMIT in DELETE queries

phpdoc fixes, no code changes

Beside some small improvements and bug fixes this will probably the final state for OC8.

To test this you need to set up two ownCloud instances. Let's say:

URL: myPC/firstOwnCloud user: user1
URL: myPC/secondOwnCloud user: user2
Now user1 can share a file with user2 by entering the username and the URL to the second ownCloud to the share-drop-down, in this case "user2@myPC/secondOwnCloud".

The next time user2 login he will get a notification that he received a server-to-server share with the option to accept/decline it. If he accept it the share will be mounted. In both cases a event will be send back to user1 and add a notification to the activity stream that the share was accepted/declined.

If user1 decides to unshare the file again from user2 the share will automatically be removed from the second ownCloud server and user2 will see a notification in his activity stream that user1@myPC/firstOwnCloud has unshared the file/folder from him.

* LDAP with multiple servers also proved backendName

The default value of the $format parameter of the APCIterator constructur is
APC_ITER_ALL which instructs the iterator to provide all available information
on cache values being iterated over. Only the key value is necessary for
matching and deletion via apc_delete(), though.

This prevents a "Format values FILENAME, DEVICE, INODE, MD5, NUM_HITS, MTIME,
CTIME, DTIME, ATIME, REFCOUNT not supported yet." notice on HHVM.

filesize(null) yields an int on HHVM and thus exif_imagetype(null) is called.

Fix #12939

As discussed at https://github.com/owncloud/core/pull/12912#issuecomment-67391155

Without this OCS on LDAP is broken for API requests coming via Basic Authentication...

Potentially fixes https://github.com/owncloud/core/issues/12915 and opens the door for potential other bugs...

Please test very carefully, this includes:

- Testing from OCS via cURL (as in #12915)
- Testing from OCS via browser (Open the "Von Dir geteilt" shares overview)
- WebDAV
- CalDAV
- CardDAV

In contrast to the previous solution, this also works on HHVM.

Added oc:tags and oc:favorites in PROPFIND response.
It is possible to update them with PROPPATCH.
These properties are optional which means they need to be requested
explicitly

The existing method is deprecated and just a wrapper around the manager method. Since in the future other code paths might call this function instead we need to perform that check here.
