Subject: Tests: do not bound test app iterations when in background mode
X-Git-Tag: v2.10.6~29
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=98342ba35112a86b914185e64f166c7e36012474;p=lttng-tools.git

Tests: do not bound test app iterations when in background mode

On systems with a high number of CPUs and slow disk, taking snapshots
can take a long time. When running a long regression test, the tests
sometimes outlive the test application.

The test application then exits since the required number of
iterations was completed
(NR_ITER=2000000).

Set the iterations parameter to -1 to ensure the application keeps
producing events for the duration of the test.
