Some early feedback. I haven't had a closer look yet, nor did I test this. Will do ASAP.
Thanks!

lib/private/Contacts/ContactsMenu/ContactsStore.php

+	 *  1. filter the current user
+	 *  2. if the `shareapi_exclude_groups` config option is enabled and the
+	 * current user is in an excluded group it will filter all local users.
+	 *  3. if the ``shareapi_only_share_with_group_members config option is


Should be

`shareapi_only_share_with_group_members`

I guess

ChristophWurst · 2017-07-07T11:30:49Z

? true : false is not necessary, the === check will already result in a boolean value.

same as above

rotanid · 2017-08-03T23:24:13Z

milestone nextcloud 13?? i would definitely call this serious privacy problem a regression that has to be fixed with the next maintenance release.

ChristophWurst

Tested and works as expected. Thanks a lot 👍

I've left some comments regarding coding style.

should be @param Entry[] $entries

lib/private/Contacts/ContactsMenu/ContactsStore.php

+	 * @param $entries Entry[]
+	 * @return array the filtered contacts

array instead of Array

great to have this tested 👍

LEDfan · 2017-08-05T14:19:51Z

@ChristophWurst I addressed your issues, thanks for testing.

@rotanid I do agree with you.
@karlitschek should this be backported to 12?

karlitschek · 2017-08-05T20:04:15Z

i think this should be backported

LEDfan · 2017-08-06T09:50:51Z

I just realized that the ContactsStore API probably should be public, so apps who interact with the contacts menu knows which contacts are available in the menu. E.g. in the Chat app we want to limit chatting to the users available in the Contacts menu (i.e. filtered by this PR)

An alternative way could be to move the filtering to the ContactsManager API.

What do you think?

LEDfan · 2017-08-14T09:48:25Z

@ChristophWurst I fixed a bug and also updated the findOne method because that wasn't filtered already.

LEDfan · 2017-08-31T17:08:42Z

@MorrisJobke @LukasReschke @blizzz @rullzer @schiessle @nickvergessen @georgehrke Excuse me for pinging you all 😄 , but can someone please review this? There are many people asking for this.

Also please point out your opinion about #5585 (comment) and #5107 (comment)

Thanks!

LukasReschke · 2017-09-15T12:29:59Z

I'll review this and additionally revert 56a9084 in here and add the handling here itself.

Rebased upon master.

…letion is disabled" This reverts commit 56a9084.

This adjusts the contacts menu to also support searching by email address which is relevant in scenarios where no UID is known such as LDAP, etc. Furthermore, if `shareapi_allow_share_dialog_user_enumeration` is disabled only results are shown that match the full user ID or email address. Signed-off-by: Lukas Reschke <[email protected]>

LukasReschke · 2017-09-15T14:04:57Z

I added 5896176...705432c, in particular:

Searching for email addresses with shareapi_allow_share_dialog_user_enumeration is now possible again as it was in stable11:

The contacts menu in the top right show contacts if a full UID or the full email has been searched for:

Note that the search is on "UID" and "EMAIL". So "FN" is not searched.

Seems all fixed

LukasReschke

Works 👍

danxuliu

CI complains because reverted commit was not signed, but as it is a revert commit it is not a big deal.

Tested and works; code looks good (but, please, next time do not mix code style changes and behaviour changes in the same commit!) 👍

LEDfan · 2017-09-16T11:06:07Z

@LukasReschke thanks for taking care of this!

Note that the search is on "UID" and "EMAIL". So "FN" is not searched.

Is there a reason for? E.g. on LDAP you as user would know the FN but not the UID?

LukasReschke · 2017-09-16T11:52:11Z

Is there a reason for? E.g. on LDAP you as user would know the FN but not the UID?

Mainly because we have a business requirement requiring this behaviour: Filtering via UID / EMAIL should be possible but for whatever reason filtering to FN shouldn't be possible.

cc @oparoz Or would filtering for complete FN here also be acceptable? Your call 😉
