Hi,
When delete-by-moving-to-trash is t and system-move-file-to-trash is not
defined, move-file-to-trash moves the deleted file to system trash can
following freedesktop.org trash can specification.
In this condition, when a file is deleted and it has the same name as the
one of an already deleted file in trash can, move-file-to-trash generates
another file name by using make-temp-file to avoid the name collision.
Unfortunately, it does put a wrong name with suffix ".trashinfo".
For example, when 2 "hoge.txt" are deleted, expected files are like:
/home/myusername/.local/share/Trash/files:
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txt
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txtwmWP0h
/home/myusername/.local/share/Trash/info:
-rw-rw-rw- 1 myusername 75 2019-10-25 20:00 hoge.txt.trashinfo
-rw------- 1 myusername 75 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
However, the reality is the 2nd trash file in files directory is named
wrongly with ".trashinfo" suffix like:
/home/myusername/.local/share/Trash/files:
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txt
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
^^^^^^^^^
/home/myusername/.local/share/Trash/info:
-rw-rw-rw- 1 myusername 75 2019-10-25 20:00 hoge.txt.trashinfo
-rw------- 1 myusername 75 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
Here is a potential patch.

Hi,
When delete-by-moving-to-trash is t and system-move-file-to-trash is not defined, move-file-to-trash moves the deleted file to system trash can following freedesktop.org trash can specification.
In this condition, when a file is deleted and it has the same name as the one of an already deleted file in trash can, move-file-to-trash generates another file name by using make-temp-file to avoid the name collision. Unfortunatelly, it does the naming in a wrong way.
For example, when 2 "hoge.txt" are deleted, expected files are like:
/home/myusername/.local/share/Trash/files:
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txt
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txtwmWP0h
/home/myusername/.local/share/Trash/info:
-rw-rw-rw- 1 myusername 75 2019-10-25 20:00 hoge.txt.trashinfo
-rw------- 1 myusername 75 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
However, the reality is the 2nd trash file in files directory is named wrongly with ".trashinfo" suffix like:
/home/myusername/.local/share/Trash/files:
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txt
-rw-rw-rw- 1 myusername 10 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
^^^^^^^^^
/home/myusername/.local/share/Trash/info:

-rw------- 1 myusername 75 2019-10-25 20:00 hoge.txtwmWP0h.trashinfo
