testsuite.yml

#
# Run the tests on various build configurations and various operating systems.
#
# In the Perl/perl5 repository all jobs are run by default.
#
# To enable the testing on a fork of the perl5 repository you first need to
# enable GitHub Actions in 'Settings' -> 'Actions' -> 'General'.
#
# When actions are enabled then it will - by default - run the 'Sanity Check' job.
#
# Testing other build configurations is controlled by the 'Secrets' configured
# in 'Settings' -> 'Secrets and Variables' -> 'Actions' -> 'Variables':
#   - DO_EXTENDED_TESTING: when this var exists and is set to a true value then
#     all build configurations are tested;
#   - CI_SKIP_SANITY: if set to a true value then most of the 'Sanity Check' job is skipped;
#   - CI_FORCE_LINUX: if set to a true value: run the 'linux' job;
#   - CI_FORCE_LINUX_I386: if set to a true value: run the 'linux-i386' job;
#   - CI_FORCE_INSTALL: if set to a true value: run the 'install' job;
#   - CI_FORCE_MACOS: if set to a true value: run the 'smoke-macos-catalina-xcode12' job;
#   - CI_FORCE_MSVC142: if set to a true value: run the 'windows-msvc142' job;
#   - CI_FORCE_MINGW64: if set to a true value: run the 'mingw64' job;
#   - CI_FORCE_CYGWIN: if set to a true value: run the 'cygwin' job;
#   - CI_FORCE_MINITEST: if set to a true value: run the 'miniperl' job;
#   - CI_FORCE_ASAN: if set to a true value: run the 'ASAN' job;
#   - CI_FORCE_PERL_UNICODE: if set to a true value: run the 'PERL_UNICODE' job;
#   - CI_FORCE_DIST_MODULES: if set to a true value: run the 'dist-modules' job;
#
# For the purpose of this workflow:
#   - 'true value': any value that is not false
#   - 'false value':
#      * empty string
#      * string containing only spaces (i.e. '    ')
#      * string containing only zeroes (i.e. '0', '0000')
#      * string containing only spaces and zeroes (i.e. '0  0 0 0')
#
# Example: if you only want to run tests on cygwin then you can set:
#   - DO_EXTENDED_TESTING=0
#   - CI_SKIP_SANITY=1
#   - CI_FORCE_CYGWIN=1
#   - (and all other CI_FORCE_... vars to 0)

# I don't think that we can (safely) set TEST_JOBS=2 in the global environment,
# because on Win32 the various Makefile's `test` target is actually ./harness,
# and it would (attempt to) honour the $ENV{TEST_JOBS} setting. This won't end
# nicely as unlike BSD (etc), Win32 sockets can drop data at process exit, which
# would cause missing TAP and hence spurious test failures.

  # "linux-i386" tests -Uusethreads without -DDEBUGGING
  # All builds in the "linux" matrix test with -DDEBUGGING
  #
  # "sanity_check" sets `fetch-depth: 0` so that it does a git clone
  # with full history, and hence can run t/porting/cmp_version.t etc
  #
  # The git-related tests require full history, but we only need to run
  # them once (they aren't platform specific).  Hence leave the others
  # with the default setting (1), which performs a shallow clone. In
  # these shallow checkouts, the git related porting tests skip (or
  # rapidly pass), but they won't fail spuriously.
  #
  # TODO - Now that we do not use secrets and instead use vars for the
  # control of which tests we run (due to the way secrets are elided
  # from the output), we can simplify the shell code below.  The
  # following url includes discussion on what next steps we could take
  # to simplify the complexity of this code.
