Description
Symfony version(s) affected: 3.4+
Description
When using bin/console debug:container my_service --show-arguments and this service contains an argument as !tagged my_tag, it will not properly show the arguments being passed. The XML will only contain a "tagged" element and doesn't tell you which services will be injected. The command line output will tell you there are 0 elements in the iterator.
How to reproduce
services:
my_service:
class: stdClass
arguments: [!tagged my_tag]
my_tagged_service_1:
class: stdClass
tags: [my_tag]
my_tagged_service_2:
class: stdClass
tags: [my_tag]To verify the services are actually there:
bin/console debug:container --tag=my_tag
Symfony Container Public Services Tagged with "my_tag" Tag
==========================================================
--------------------- ------------
Service ID Class name
--------------------- ------------
my_tagged_service_1 stdClass
my_tagged_service_2 stdClass
--------------------- ------------
Missing argument information:
bin/console debug:container my_service --show-arguments
Information for Service "my_service"
====================================
---------------- -------------------------
Option Value
---------------- -------------------------
Service ID my_service
Class stdClass
Tags -
Public yes
Synthetic no
Lazy no
Shared yes
Abstract no
Autowired yes
Autoconfigured yes
Arguments Iterator (0 element(s))
---------------- -------------------------
Possible Solution
I would personally already be satisfied if it properly displayed the actual count, and it would be even better if it could display the list of service_ids it would inject.
Iterator (2 element(s))
# or
Tagged Iterator (2 element(s)) [
my_tagged_service_1
my_tagged_service_2
]
This is currently making it a bit troublesome to see if your !tagged works and in a more complex system (autoconfigure), if all the services are picked up correctly.
