Description Tomas Pelka 2009-01-29 05:28:14 UTC

Description of problem:
Dbus-send unable to send dict arguments.

Version-Release number of selected component (if applicable):
dbus-1.1.2

How reproducible:
100%

Steps to Reproduce:
1. Send:
dbus-send --print-reply --dest=org.freedesktop.DBus --type=signal \
/org/freedesktop/DBus/Examples/Echo org.freedesktop.DBus.Hello \ dict:string:int32:"one",1,"two",2,"three",3

Expected results:
Message should be send without error.

Actual result:
process 13920: arguments to dbus_message_iter_open_container() were incorrect, assertion "(type == DBUS_TYPE_STRUCT && contained_signature == NULL) || (type == DBUS_TYPE_DICT_ENTRY && contained_signature == NULL) || (type == DBUS_TYPE_VARIANT && contained_signature != NULL) || (type == DBUS_TYPE_ARRAY && contained_signature != NULL)" failed in file dbus-message.c line 2356.
This is normally a bug in some application using the D-Bus library.

Comment 1 Tomas Pelka 2009-01-29 05:29:25 UTC

I'm not sure, but it seems to be a dbus-send bug.

Comment 2 Simon McVittie 2011-04-07 10:10:51 UTC

I didn't even know dbus-send was meant to be able to send dicts. Looking at the code, it seems "dict" may secretly mean "dict entry" for dbus-send, so the right syntax might be array:dict:string:int32?

Using gdbus, qdbus or a Python script is probably better for non-trivial data structures.

If someone wants this, patches welcome.

It is difficult for non-programmers to deduct the bug and your guide is making them enable to detect and debug. I am configuring the plugin on https://mentalitch.com/tips-i-would-like-to-know-when-i-write-my-first-assignment/ website in the post. I am pretty sure it will be more responsive.

Comment 9 Jeena 2019-07-30 12:18:30 UTC

I think it’s important to look at where you are in life and what you want people to associate your name and personal brand with. I am comfortable swearing and writing about controversial topics, for example, but there are certain things you’ll never find associated with my brand.
