Subject: Test: utils: introduce LTTNG_SESSIOND_ENV_VARS
X-Git-Tag: v2.11.0-rc1~552
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=4b01971f9df6293ace728642f15f5262691cec66;p=lttng-tools.git

Test: utils: introduce LTTNG_SESSIOND_ENV_VARS

When LTTNG_SESSIOND_ENV_VARS is set when calling start_lttng_sessiond_*
the value from LTTNG_SESSIOND_ENV_VARS will be passer to the "env"
command while launching the sessiond.

Allow the use of LD_PRELOAD, LTTNG_ENABLE_TESTPOINT and others.
