vim-patch:8.1.2342: random number generator in Vim script is slow Problem: Random number generator in Vim script is slow. Solution: Add rand() and srand(). (Yasuhiro Matsumoto, closes vim/vim#1277) https://github.com/vim/vim/commit/06b0b4bc27077013e9b4b48fd1d9b33e543ccf99 Add missing method call usage to builtin.txt. vim_time and test_settime is N/A. Add a modeline to test_random.vim. Use typval_T* over listitem_T* vars so we don't need to use TV_LIST_ITEM_TV all over the place... Remove NULL list checks (tv_list_len covers this).

vim-patch:9.0.1015: without /dev/urandom srand() seed is too predictable (#21303) Problem: Without /dev/urandom srand() seed is too predictable. Solution: Use micro seconds and XOR with process ID.

vim-patch:8.1.2343: using time() for srand() is not very random Problem: Using time() for srand() is not very random. Solution: use /dev/urandom if available https://github.com/vim/vim/commit/07e4a197953d12902fb97beb48830a5323a52280 Use os_open and os_close. time_settime is N/A, so some parts of the test are disabled. There's maybe a very, very, very, very small chance the /dev/urandom test fails, but it shouldn't matter. :P
