# Description: test cases for sandbox2 unit tests.
#
# Some of the following cc_binary options avoid dynamic linking which uses a
# lot of syscalls (open, mmap, etc.):
#   linkstatic = True                 Default for cc_binary
#   features = ["fully_static_link"]  Adds -static
#
# Note that linking fully static with an unmodified glibc is not generally
# considered safe, due to glibc relying heavily on loading shared objects at
# runtime.
# The rule of thumb when it is safe to do so is when the program either only
# uses plain syscalls (bypassing any libc altogether) or if it does not use
# any networking and none of the functionality from cstdio/stdio.h (due to
# auto-loading of locale-specific shared objecs).
