Sean Dewar	4f7a8991a9	vim-patch:8.2.0233: crash when using garbagecollect() in between rand() ... Problem: Crash when using garbagecollect() in between rand(). Solution: Redesign the rand() and srand() implementation. (Yasuhiro Matsumoto, closes vim/vim#5587, closes vim/vim#5588) 4f645c54ef Omit test_srand_seed. Unmacroify SHUFFLE_XOSHIRO128STARSTAR and SPLITMIX32 while we're at it (leave ROTL alone as it's fairly innocent).	2022-02-05 14:01:00 +00:00
Sean Dewar	cc7ccf6d31	vim-patch:8.1.2357: no test with wrong argument for rand() ... Problem: No test with wrong argument for rand(). Solution: Add a test case. 68e9e5f7fc	2022-02-05 14:00:59 +00:00
Sean Dewar	c97614d98f	vim-patch:8.1.2356: rand() does not use the best algorithm ... Problem: rand() does not use the best algorithm. Solution: use xoshiro128** instead of xorshift. (Kaito Udagawa, closes vim/vim#5279) f8c1f9200c	2022-02-05 14:00:59 +00:00
Sean Dewar	f6a0d5498b	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 07e4a19795 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	2022-02-05 14:00:35 +00:00
Sean Dewar	22f0725aac	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) 06b0b4bc27 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).	2022-02-05 13:16:34 +00:00
