38 * Queue A. Initially the max active is set to 2 and then reduced to 0 - this
39 * should block op2 even after op1 has finished. Later the max active is set to
40 * 2 and this should start op2
42 struct OperationQueue *q1;
45 * Queue B. Max active set to 2 is not changed throughout the test
47 struct OperationQueue *q2;
50 * This operation should go into both queues and block op2 until it is done
52 struct GNUNET_TESTBED_Operation *op1;
55 * This operation should go into q1 and q2
57 struct GNUNET_TESTBED_Operation *op2;
60 * This operation should go into both queues and should consume 2 units of
61 * resources on both queues. Since op2 needs a resource from both queues and is
62 * queues before this operation, it will be blocked until op2 is released even
63 * though q1 has enough free resources
65 struct GNUNET_TESTBED_Operation *op3;
68 * Just like op3, this operation also consumes 2 units of resources on both
69 * queues. Since this is queued after op3 and both queues are at max active
70 * 2. This will be blocked until op3 is done.
72 struct GNUNET_TESTBED_Operation *op4;
75 * This operation is started after op4 is released and should consume only 1
76 * resource on queue q1. It should be started along with op6 and op7
78 struct GNUNET_TESTBED_Operation *op5;
81 * This operation is started after op4 is released and should consume only 1
82 * resource on q2. It should be started along with op5 and op7
84 struct GNUNET_TESTBED_Operation *op6;
87 * This operation is started after op4 is released and should consume 1 resource
88 * on both queues q1 and q1. It should be started along with op5 and op6. It is
89 * then inactivated when op6 is released. op8's start should release this
90 * operation implicitly.
92 struct GNUNET_TESTBED_Operation *op7;
95 * This operation is started after op6 is finished in step task. It consumes 2
96 * resources on both queues q1 and q1.
