James Peach created MESOS-3725:
----------------------------------
Summary: shared library loading depends on environment variable
updates
Key: MESOS-3725
URL: https://issues.apache.org/jira/browse/MESOS-3725
Project: Mesos
Issue Type: Bug
Components: modules, stout
Reporter: James Peach
{{ModuleTest::SetUpTestCase()}} and the various {{libraries::paths()}} is stout
assume that updating {{LD_LIBRARY_PATH}} or {{DYLD_LIBRARY_PATH}} is sufficient
to alter the search path used by dlopen(3). It is not; those environment
variables are only bound at program load.
My preference is to fix this by requiring the clients of {{DynamicLibrary}} to
always pass in an absolute path and to remove all mention of these environment
variables.
FWIW, the tests in {{ModuleTest::SetUpTestCase()}} only work because the
libtool wrapper script sets up the library path to the expected value prior to
running the tests.
