I'm working on pam_sss.so tests and I ran into a problem that I don't
know how to solve best.
tl;dr, I would like to set different environment variables for different
tests in order to set up cwrap libraries differently per-test.
I can't use setenv() in the test itself, because that's too late, I need
the variables to be set when __attribute__(constructor) is run, so normally
at program startup, when the libraries are loaded.
With cmake it's easy, use set(TEST_ENVIRONMENT). But with autotools, I
only found two ways:
- TESTS_ENVIRONMENT - this is fine, but it's per Makefile.am. So I
would have to split the tests more, into pam_wrapper tests that also
require uid_wrapper, tests that only require pam_wrapper, ...
- LOG_COMPILER - this allows to run a wrapper script before a test
that receives the test name as argv. So this is pretty much what I
want except this is a feature new to automake 1.12, which would
rule out both RHEL-6 and Ubuntu Trusty (which is used by Travis)
So I'm really leaning towards creating a src/tests/cwrap/pwrap/Makefile.am
and src/tests/cwrap/pwrap_root/Makefile.am. The downside of multiple
Makefile.am files is that there is some code duplication and the build
takes longer. But I still think there is enough interest (from us and from
our users) to support git master on old platforms. I can file a ticket to
remove this and use LOG_COMPILER when we drop support for RHEL-6 and old
If you disagree, please reply, otherwise I'm going to send a patch with
42% code coverage, up from 0% last week. Woo!
