Software needed for running "make check"

On Ubuntu or Debian systems, a number of packages need to be installed in order for "make check" to function. These include:

  • dejagnu
  • expect
  • tcl
  • tcl-dev (needed by test programs that are extensions to the tcl program)
  • portmap (needed by lib/rpc-unit-test)
  • csh (or maybe tcsh; needed by some of the libdb2 tests)

Known test suite issues

On Linux systems, sometimes the --disable-rpath option to configure is required in order to avoid problems with previously-installed versions of MIT krb5. Alternatively, you can run "make install" before "make check".

The calls to krb5_c_random_os_entropy that pass the value 1 in the strong argument, which causes the library to read from the strong OS random number source, can cause stalls and timeouts in the test suite. Changing those calls to pass 0 instead will reduce the stalls. We need to have a better way to disable the reading of strong random numbers during tests. This is primarily a problem on Linux systems.

If an existing kdc.conf exists in the "installed" location, it can disrupt the automated tests, especially if it contains syntax errors.

On recent Debian or Ubuntu systems, a bug in expect that can cause stalls in the dejagnu parts of the test suite is documented at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=421187

The testing user's shell must be listed in /etc/shells or the gssftp tests will fail. This will cease to be a concern for the main krb5 test suite if and when the applications are unbundled into a separate package.

The rlogin and telnet dejagnu tests require root access; without it, the test suite will skip those tests. To run these tests, you can either run the test suite as root, or arrange for "rlogin <localhostname> -l root -x" to succeed. (The environment variables RLOGIN and RLOGIN_FLAGS can override the "rlogin" and "-x" parts of that command line.) This will also cease to be a concern for the main krb5 test suite if and when the applications are unbundled.
