patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll' Commit: https://github.com/vim/vim/commit/02fcae02a926e4e8379d77fb716da4202029882d Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Wed Feb 21 19:40:44 2024 +0100 patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll' Problem: infinite loop in win_update with 'smoothscroll' set when window width is equal to textoff, or signed integer overflow if smaller. Solution: don't revalidate wp->w_skipcol in that case, as no buffer text is being shown. (Sean Dewar) Don't instead reset w_skipcol; that would lose the scroll position within the line, which may be undesirable if the window is made wider later. Also include changes from the splitmove PR #14042 that I (in my infinite Git wisdom) forgot to commit. This includes a change to Test_window_split_no_room to ensure it doesn't fail for some screen sizes. Move Test_smoothscroll_in_zero_width_window to test_scroll_opt.vim, as that file feels more appropriate. closes: #14068 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
