---------------------------------------
Summary: Make it possible to reliably inject environment variables
into forked processes
Key: MESOS-8229
URL: https://issues.apache.org/jira/browse/MESOS-8229
Project: Mesos
Issue Type: Improvement
Components: agent, containerization, master
Reporter: Benjamin Bannier
We should consider supporting reliable injection of environment variables into
forked processes, e.g., to customize dynamic library loading with
{{LD_PRELOAD}} or the influence the behavior of the used runtime (e.g., glibc
options). Customary, environment variables are used for this, but we tend to in
many cases strip away all but a hardcoded set of flags (e.g., when starting
executors). The possible set of these flags seems to be open.
I came across this when trying to run our test suites with a build with clang
address sanitization enabled (passing {{-fsanitize=address}} in the compiler
flags). This links in a C runtime which aborts processes if memory leaks are
detected. These aborts can be disabled by passing runtime options in an
environment variable {{ASAN_OPTIONS}}, but unfortunately, it is not effective
in all forked processes.
