If set the number of history saves is 0, assertions fail when inserting an entry on exit.
Dont insert an entry when the number of saves is 0 fixes the issue.
fixes#11497
Since 8b8ecf4, the shada module loads files in the jumplist to properly
clear duplicates. This can trigger some autocommands, which in turn
saves and restores search and substitute patterns, freeing the previous
strings in "spats" which are held in "wms" as well (heap-use-after-free).
To avoid this, initialize the jumplist in "wms" before search patterns.
It is otherwise impossible to determine which test failed sanitizer/valgrind
check. test/functional/helpers.lua module return was changed so that tests which
do not provide after_each function to get new check will automatically fail.
Note: it looks like viminfo files do not store search direction intentionally.
After reading viminfo file search direction was considered to be “forward”.
Note 2: all files created on earlier Neovim version will automatically receive
“forward” direction.
Fixes#3580
- Remove unused variables.
- Do not use helpers.nvim_feed in most cases.
- Do not use helpers.nvim and helpers.nvim_eval at all.
- Add helpers.funcs and helpers.\*meths special tables. Indexing such table
creates functions which call helpers.call or helpers.nvim (and similar) with
first argument equal to table index.
