This reverts commit c945f58. I initially removed the workflow because it was failing all the time and always seeing commit messages with failed CI checks is not only pretty unhelpful but we might miss other *relevant* failures because of that. So this brings back the workflow for Darwin since we're now actually working on at least trying to implement support for it. The reason why I'm not adding this *after* adding support is that I don't have a Mac OS X machine, so I have to purely relying on the GitHub Actions workflow. Signed-off-by: aszlig <aszlig@nix.build>
While LOCAL_PEERCRED is somewhat similar to SO_PEERCRED, we unfortunately don't have access to the PID of the remote peer. This is something we actually need to properly distinguish the remote peer by giving it an IP address with the PID encoded, otherwise we'd end up with duplicate IPs. On the other hand, using random IP addresses also is not a very good solution here, since we actually *want* to have the same IP for the same process. Right now the UID and GID fields are not used at all on Darwin, but we really need to figure out a way to properly assign fake IP addresses. Signed-off-by: aszlig <aszlig@nix.build>
This is needed in order to run integration tests, which we certainly want to run on Darwin, because I do not have a single machine running MacOS and thus for me the only way to check whether something is broken is by checking whether the integration tests have failed.

This is a WIP branch to implement support for Mac OS X, which in theory should work since it has a similar mechanism (
DYLD_INSERT_LIBRARIES) toLD_PRELOADon GNU/Linux.Fundamental issues:
LOCAL_PEERCRED. It seems that there is onlyxucred.cr_uid, but in order to provide fake client IPs we need at least the peer PID to properly distinguish the individual peers.We can't useAccording to https://ubuntu.com/18-04, the standard support has expired on 31 May 2023.std::filesystemyet, because Ubuntu 18.04 is still using GCC 7. Find a less ugly way toget_current_dir_namein a cross-platform way.
