--- Comment #1 from Petr Pisar ppisar@redhat.com --- This is caused by upgrading perl-Term-ReadLine-Gnu from 1.25 to 1.26. The dead-lock is here:
$ prove -b -v t/07-initialize.t t/07-initialize.t .. 1..4 ok 1 - initialize with prams LOCK ok 2 - quit with prams ok 3 - initialize without prams ok 4 - quit witout prams ok
Either is a bug in the perl-Term-ReadLine-Gnu or it's a race in the test because of suspicious sleep call:
ok( my $debugger = Debug::Client->new( host => $host, port => $port, porto => $porto, listen => $listen, reuse => $reuse_addr ), 'initialize with prams' ); $debugger->run;
sleep 1;
ok( $debugger->quit, 'quit with prams' );

--- Comment #2 from Petr Pisar ppisar@redhat.com --- It halts in the $debug->run on reading response from perl debugger.
The Debug::Client::run() sends "c" command to the debugger and waits for a response. But no response comes because the "c" command is not flushed from buffers to the TCP socket.
This is caused by Term-ReadLine-Gnu commit:

--- Comment #3 from Petr Pisar ppisar@redhat.com --- Actualy the "c" command is flushed, but it's emitted before perl debugger is ready to process input. Either the debugger should buffer the input, or the Debug::Client should wait for debugger prompt. At the end, it's a race.

--- Comment #4 from Petr Pisar ppisar@redhat.com --- There still something fishy with the perl debuger: It does not emit "DB<1>" prompt if the debugger is run from the t/07-initialize.t test. If the debugger is run from another session, it emits the "DB<1>". That explains why the debugger does not process the "c" command. But I don't know why the behaviour differs.
