Blender Version
Broken: version: 2.93, 3.6, 4.0
Worked: none

Short description of error
When duplicating an object with a parent and using context.copy() with the object.duplicate or any other operator that uses object.duplicate the child object to get a wrong name.

Exact steps for others to reproduce the error

set one object as a parent of another
select both objects (parent and child)
run this code in the Text Editor
now take a look in the outline the duplicated parent is selected, but the origin child is also selected and the name of the origin child has changed

import bpy
bpy.ops.object.duplicate_move(bpy.context.copy())

import bpy

with bpy.context.temp_override(**bpy.context.copy()):
    bpy.ops.object.duplicate_move()

Thanks, but Blender 2.93 is supported until June 2023 and does not support temp_override(), so I made a report

Note: The Problem does not occur with temp_override()

Can confirm. Though not sure whether this will be fixed in 2.93

2.93 will not see another release, not sure though if we should close this now, since deprecated does not necessarily mean we dont accept bug reports for this (or maybe it does, will ask around)?

If I do the Context.temp_override equivalent of overriding everything in the dict created by bpy.context.copy() then I get the same odd renaming behaviour (using 4.0.0a 2023-06-03 ab6860f3de0f):

import bpy

with bpy.context.temp_override(**bpy.context.copy()):
    bpy.ops.object.duplicate_move()

Edit: It looks like all that's needed is to override selected_editable_objects with whatever its current value is:

import bpy

with bpy.context.temp_override(selected_editable_objects=bpy.context.selected_editable_objects):
    bpy.ops.object.duplicate()

If I do the `Context.temp_override` equivalent of overriding everything in the `dict` created by `bpy.context.copy()` then I get the same odd renaming behaviour (using 4.0.0a 2023-06-03 `ab6860f3de0f`): ```py import bpy with bpy.context.temp_override(**bpy.context.copy()): bpy.ops.object.duplicate_move() ``` Edit: It looks like all that's needed is to override `selected_editable_objects` with whatever its current value is: ```py import bpy with bpy.context.temp_override(selected_editable_objects=bpy.context.selected_editable_objects): bpy.ops.object.duplicate() ```

In newer version (4.0), context argument for operator call is removed: ac263a9bce

Use of temp_override is recommended and 3.3LTS supports it. So I think we can close this report.

Maybe we can open a separate report for it?

I'm not really sure this needs to be closed, the report was that using an override with context.copy() causes unexpected behaviour, which is the case with both the deprecated context override argument and temp_override. The reporter's claim that the problem did not occur with temp_override was incorrect.

If I were to open a new report it would be identical aside from the sample code would use temp_override with context.copy() instead of the override argument (or just overriding selected_editable_objects since I tracked that down as the cause).

discussion and original report was quite misleading than the actual problem (which you've found), hence closed :)
Anyways, we can reopen the report with few edits.
