The "openssl" alias now defaults to OpenSSL 3.0, which produces a lot of
deprecation warnings. To avoid build failures due to `-Werror`, stay with
OpenSSL 1.1 until we can get rid of these issues.
Use the same configure options etc. for both builds (no need for the cert
options as we don't use TLS or X.509 parsing) and switch to a Git commit
that includes the SHA-3 OID fix (it's actually the fix itself).
On 18.04, setuptools was apparently pulled in by python-pip but is not
by python3-pip and on Ubuntu 16.04 there is an issue with tox when
installed via pip3 (syntax error in one of the dependencies) and with
pip that dependency is not even available.
That's because forks are currently not allowed to be analyzed by LGTM (unlike
with SonarCloud) so this check can't actually be successful for forks even if
variables are defined.
References strongswan/strongswan#328.
The nm test can only be done on Ubuntu 18.04 as the required libraries
are not available on newer systems.
Switch to pip3 to install tox (the only Python dependency we use).
Closesstrongswan/strongswan#327.
On travis-ci.com (travis-ci.org will be discontinued by the end of the
year) we are now charged for each minute. We only got 10000 credits in
a trial plan, which we used up with a few builds. Minutes also cost a
different amount of credits on different platforms: 10 on Linux,
but 50 on macOS (installing the dependencies on macOS alone took 12-15
minutes on Travis for some reason, takes about half on Github's runners).
No native Windows build yet as we have the same issue as on AppVeyor where
threading/streaming tests might get stuck. And there is also only a
single Windows platform to test on. Plus building/testing on Windows is
very slow (and getting ccache to work seems tricky).
The 'sw_collector' test case had to be disabled because we can't access
/usr/local/share on the Github build hosts (the process is just blocked
in readdir() and eventually times out).
Unfortunately, we can't test on different architectures anymore (in
particular ARM and the big-endian IBM Z/x390x).
Manually built dependencies are now built in a separate step after
packages have been installed as they might depend themselves on some
packages (e.g. tpm2-tss, which now requires libjson-c).
SHA-3 is only automatically enabled on x86/x64. The tests are disabled
because we don't need them and they currently cause a compile warning/error
when built with clang on x64 (sizeof() on a pointer to an array). If the
examples are enabled, another test suite is built, which includes the
disabled crypto tests.
This reverts commit d450e926de65e5517293d38ec3ad2a1a17020d05.
Was fixed by making tox depend on newer versions of six so the package
gets installed/updated automatically now when installing tox. There is
also some ongoing work that tries to make virtualenv work with older
versions of six.
Bash is not installed on the FreeBSD images here and the location would
be different anyway (`/usr/local/bin/bash`, so we'd have to change the
hashbang to e.g. `/usr/bin/env bash`).
The build system is a bit limited, only the repository directory and
LGTM_WORKSPACE is writable. sudo doesn't work at all, for others we
don't have enough permission.
