Hi,
It looks like the following bots assigned to you started failing recently:
http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv7-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv7-linux-noe...
The failing tests are all filesystem tests:
FAIL: libc++::assign.pass.cpp FAIL: libc++::path.pass.cpp FAIL: libc++::replace_filename.pass.cpp FAIL: libc++::refresh.pass.cpp FAIL: libc++::file_size.pass.cpp FAIL: libc++::file_type_obs.pass.cpp FAIL: libc++::hard_link_count.pass.cpp FAIL: libc++::last_write_time.pass.cpp FAIL: libc++::ctor.pass.cpp FAIL: libc++::ctor.pass.cpp FAIL: libc++::increment.pass.cpp FAIL: libc++::exists.pass.cpp FAIL: libc++::is_block_file.pass.cpp FAIL: libc++::is_character_file.pass.cpp FAIL: libc++::is_directory.pass.cpp FAIL: libc++::is_empty.pass.cpp FAIL: libc++::is_fifo.pass.cpp FAIL: libc++::is_other.pass.cpp FAIL: libc++::is_regular_file.pass.cpp FAIL: libc++::is_socket.pass.cpp
Having seen some of these issues before, I strongly suspect this is due to the fact that your builder is running as root. Libc++'s filesystem tests are known to fail when run as root, because some of them need to check for failure to access some files for which there's no permission. This doesn't seem to work when run as root.
Can you work with us to resolve this issue?
Thanks, Louis
