System Information
Operating system: Win10
Graphics card: GTX1080/970...any

Blender Version
Broken: Paste method for copied to clipboard elemtens

blender-2.80-ec471a9b1c14-win64
//Additional notice: Could you just make simple html mechanism that works from the Bug Report option and run that kind of link:
https://developer.blender.org/maniphest/task/edit/form/1/?version=blender-2.80-ec471a9b1c14-win64
and this could be applied via JS to the specific form text field that is named: version
//

Worked: (optional)
do not remember - but it worked in some previous versions fine

Short description of error
when use copy->paste clipboard mechanism then when paste element from buffer it does not appear selected when option SELECT at Paste Selection from Buffer is enabled.
BTW: this mechanism could have an additional very handy option: Paste into 3D Cursor place.

Exact steps for others to reproduce the error
Just use Copy and Paste with enabled SELECT option

It looks like it is selected, but not active (when another object is still active). Can you confirm that?

No, it is not.
When you copy->paste between two different files then pasted object is not selected nor active.
I checked - this is a Collection problem. When you copy->paste in the root Scene collection, then it works as should.
But when you are using other nested collections then it does not work.

Can confirm.
To me I cant get it to be selected at all (in current master -- there were some changes to appending afaics between the time of the report and today) regardless of pasting into the root Scene Collection or not.

Dug around a little in library_link_end / add_loose_objects_to_scene / add_collections_to_scene but code where FILE_AUTOSELECT flag is used is never actually reached for me.

Not sure if this is one for @mont29 (or @dfelinto possibly?)
Assigning to @mont29 first...

There are several glitches here, but I think the main issue is that when we copy and object, we also copy its collections (which triggers the 'paste and instantiate the collection instead of the object' behavior in link code when we paste the buffer).

@dfelinto, @ideasman42, any reason to also write the collections of copied objects? Doing this is going to make things a tad more complicated to handle… And it seems like bad idea to me, if we later want to add copy/paste of collections e.g… :/

I believe pasting collections when pasting an object is a side-effect of unifying groups and collections. It is also quite handy and allow you to paste an entire scene keeping its hierarchy.
Now for the actual reported bug. Even in 2.79 the selection option is not working (although there the objects are always selected).

Anyways I can look at making the pasted objects selected. And optionally - no promises - to get the "Select" option finally working.

While D4558 address the issue of selecting objects when we instantiate their collection, imho it does not really fix the main issue here.

My main concern currently with copy/paste is that you would expect it to copy/paste objects most of the time, but it actually copy/pastes collections. I really don’t think this is a good behavior, this can very quickly lead you to tens of collections in your viewlayer after only a few copy/pastes…

I think copy/paste from 3DView should only copy objects, and copy/paste of collections should be done from the outliner probably?

I agree we can stop copying collections, doesn't make much sense anymore in the current system.

Alright, committed the bit about selectability, but leaving this open to address collection (which may need to remove my code changes, anyways).
Also, there seems to be a strange bug where if I select the Cube, Ctrl+C, select all (Cube + Light + Camera), Ctrl+V it paste not only the cube but all the other objects as well.

Will check on removing collections from copy/paste from 3DView.
