Till Toenshoff created MESOS-6751:
-------------------------------------
Summary: Mesos should allow for selective environment inheritance.
Key: MESOS-6751
URL: https://issues.apache.org/jira/browse/MESOS-6751
Project: Mesos
Issue Type: Improvement
Reporter: Till Toenshoff
We have often run into issues with environment variables inherited by
subprocesses which in certain setups cause problems.
VERY recent examples are:
- MESOS-6747
- MESOS-6748
The pattern for solving an inheritance that covers bases like PATH,
LD_LIBRARY_PATH and DYLD_LIBRARY_PATH but at the same time carves out traps
like LIBPROCESS_-related variables and maybe also MESOS_-related variables is
relatively simple.
{noformat}
map<string, string> environment;
foreachpair (const string& key, const string& value, os::environment()) {
if (!strings::startsWith(key, "LIBPROCESS_") &&
!strings::startsWith(key, "MESOS_")) {
environment.emplace(key, value);
}
}
{noformat}
But maybe we can somehow force the use of such pattern to make this kind of bug
less frequent on new code that forks.
