SYNOPSISdbus−test−tool black−hole [−−session | −−system] [−−name=NAME] [−−no−read] dbus−test−tool echo [−−session | −−system] [−−name=NAME] [−−sleep−ms=MS] dbus−test−tool spam [−−session | −−system] [−−dest=NAME] [−−count=N] [−−flood] [−−ignore−errors] [−−messages−per−conn=N] [−−no−reply] [−−queue=N] [−−seed=SEED] [−−string | −−bytes | −−empty] [−−payload=S | −−stdin | −−message−stdin | −−random−size]

DESCRIPTIONdbus−test−tool is a multi−purpose tool for debugging and profiling D−Bus​. dbus−test−tool black−hole connects to D−Bus, optionally requests a name, then does not reply to messages​. It normally reads and discards messages from its D−Bus socket, but can be configured to sleep forever without reading​. dbus−test−tool echo connects to D−Bus, optionally requests a name, then sends back an empty reply to every method call, after an optional delay​. dbus−test−tool spam connects to D−Bus and makes repeated method calls, normally named com​.example​.Spam​.

OPTIONS

Common options−−session Connect to the session bus​. This is the default​. −−system Connect to the system bus​.

black−hole mode−−name=NAME Before proceeding, request ownership of the well−known bus name NAME, for example com​.example​.NoReply​. By default, no name is requested, and the tool can only be addressed by a unique bus name such as :1​.23​. −−no−read Do not read from the D−Bus socket​.

echo mode−−name=NAME Before proceeding, request ownership of the well−known bus name NAME, for example com​.example​.Echo​. By default, no name is requested, and the tool can only be addressed by a unique bus name such as :1​.23​. −−sleep−ms=MS Block for MS milliseconds before replying to a method call​.

spam mode−−dest=NAME Send method calls to the well−known or unique bus name NAME​. The default is the dbus−daemon, org​.freedesktop​.DBus​. −−count=N Send N method calls in total​. The default is 1​. −−queue=N Send N method calls before waiting for any replies, then send one new call per reply received, keeping N method calls "in flight" at all times until the number of messages specified with the −−count option have been sent​. The default is 1, unless −−flood is used​. −−flood Send all messages without waiting for a reply, equivalent to −−queue with an arbitrarily large N​. −−no−reply Set the "no reply desired" flag on the messages​. This implies −−flood, since it disables the replies that would be used for a finite −−queue length​. −−messages−per−conn=N If given, send N method calls on the same connection, then disconnect and reconnect​. The default is to use the same connection for all method calls​. −−string The payload of each message is a UTF−8 string​. This is the default​. The actual string used is given by the −−payload or −−stdin option, defaulting to "hello, world!"​. −−bytes The payload of each message is a byte−array​. The actual bytes used are given by the −−payload or −−stdin option, defaulting to the ASCII encoding of "hello, world!"​. −−empty The messages have no payload​. −−payload=S Use S as the −−string or −−bytes in the messages​. The default is "hello, world!"​. −−stdin Read from standard input until end−of−file is reached, and use that as the −−string or −−bytes in the messages​. −−message−stdin Read a complete binary D−Bus method call message from standard input, and use that for each method call​. −−random−size Read whitespace−separated ASCII decimal numbers from standard input, choose one at random for each message, and send a message whose payload is a string of that length​. −−seed=SEED Use SEED as the seed for the pseudorandom number generator, to have somewhat repeatable sequences of random messages​.

BUGSPlease send bug reports to the D−Bus bug tracker or mailing list​. See http://www​.freedesktop​.org/software/dbus/​.
