dependency version / build specific test failures in test/integration/uv

[andreasstieger]

I am investigating dependency build specific test failure in test/integration/uv.

[   61s] FAIL: test/integration/uv

Specifically:

Current rpm spec and logs in https://build.opensuse.org/package/show/devel:libraries:c_c++/raft
(also fails with libuv 1.48.0) This issue is not new, seen in 0.22.0 but I had canonical/raft before.

Anything I can dive into?

[freeekanayaka]

I'm not quite able to reproduce this (Debian/testing, with libuv 1.48.0).

Both the underlying code and the associated tests where contributed a while ago by an external contributor, and I'm not terribly familiar with it. This is also code that is not used at all by dqlite or cowsql, so I'm somehow tempted to just get rid of it.

Alternatively, would it be possible to have SSH access to a machine where I can easily reproduce this?

I can't think of any easy way to debug this via this issue.
