# The folllowing dlopen patches ensure that all the features that are
# implemented via dlopen(3) are available (or explicitly deactivated) by
# pointing dlopen to the absolute store path instead of relying on the
# linkers runtime lookup code.
#
# All of the dlopen calls have to be handled. When new ones are introduced
# by upstream (or one of our patches) they must be explicitly declared,
# otherwise the build will fail.
#
# As of systemd version 247 we've seen a few errors like `libpcre2.… not
# found` when using e.g. --grep with journalctl. Those errors should
# become less unexpected now.
#
# There are generally two classes of dlopen(3) calls. Those that we want to
# support and those that should be deactivated / unsupported. This change
# enforces that we handle all dlopen calls explicitly. Meaning: There is
# not a single dlopen call in the source code tree that we did not
# explicitly handle.
#
# In order to do this we introduced a list of attributes that maps from
# shared object name to the package that contains them. The package can be
# null meaning the reference should be nuked and the shared object will
# never be loadable during runtime (because it points at an invalid store
# path location).

# `grep -ri 'dlopen("lib' $src` and update the below list.
