The size of long varies depending on architecture, in contrast to the
MAXLNUM constant which sets the maximum allowable number of lines to
2^32-1. This discrepancy may lead to hard to detect bugs, for example
https://github.com/neovim/neovim/issues/18454. Setting linenr_T to a
fix maximum size of 2^32-1 will prevent this type of errors in the
future.
Also change the variables `amount` and `amount_after` to be linenr_T
since they're referring to "the line number difference" between two
texts.
* build: move the logic for linters to cmake
Cmake is our source of truth. We should have as much of our build
process there as possible so everyone can make use of it.
* build: remove redundant check for ninja generator
The minimum cmake version as of writing this is 3.10, which has ninja
support.
fixes#15221
I tried to reproduce with a test, but failed. The below patch is able to
cause the out of bound access (I verified by adding a check to the
code), but it doesn't seg fault or trigger asan/valgrind errors.

* on_scrollback_option_changed renamed to adjust_scrollback. The
function name did not correspond to what it was doing. It is
called unconditionally in every refresh of the terminal
unrelated if the scrollback option was changed.
* new on_scrollback_option_changed function, which calls
refresh_terminal, which then calls adjust_scrollback
* terminal_check_size is not the appropriate function to call when the
option is changed since it only conditionally adjusts the scrollback.
Use the new on_scrollback_option_changed
fixes#15477fixes#11811
Problem:
Since 22b52dd462#11501, log_path_init is called in log_init, so it is
now called at a deterministic time. So the "just in time" complexity of
log_path_init is no longer needed.
Solution:
Remove logic intended to try to "heal" partial initialization.
Problem: input() does not handle composing characters properly.
Solution: Use mb_cptr2char_adv() instead of mb_ptr2char_adv().
(closesvim/vim#10527)

Cherry-pick all of Test_input_func() from patch 8.2.0316.
problem: data race when `recursive` is read outside of mutex by thread A
while thread B has taken the mutex and modifies it.
solution: use a recursive lock.
ref #18764
Currently this is more or less a straight off reimplementation,
but this allow further optimizations down the line, especially
for avoiding memory allocations of rpc objects.
Current score for "make functionaltest; make oldtest" on a -DEXITFREE build:
is 117 055 352 xfree(ptr != NULL) calls (that's NUMBERWANG!).
clang: Result of operation is garbage or undefined
clang: Uninitialized argument value
Also check for == 's' instead of != 'n' as it is more straightforward.
Also fix another unrelated PVS warning:
PVS/V1071: Return value of win_comp_pos() is not always used
Also avoid referring to mappings as "keymaps" in commands and docs.
*map_empty_rhs* *map-empty-rhs*
You can create an empty {rhs} by typing nothing after a single CTRL-V (you
have to type CTRL-V two times). Unfortunately, you cannot do this in a vimrc
file.
- Complete function:
There was lots of unnecessary C code for the complete function, therefore
moving it to Lua and use all the plumbing we have in place to retrieve the
results.
- Moving the module:
It's important we keep nvim lua modules name spaced, avoids conflict with
plugins, luarocks, etc.
