In Vim's main_loop function, the main loop is
while (!cmdwin
#ifdef FEAT_CMDWIN
|| cmdwin_result == 0
#endif
)
{
...
#ifdef FEAT_EVAL
/*
* May perform garbage collection when waiting for a character, but
* only at the very toplevel. Otherwise we may be using a List or
* Dict internally somewhere.
* "may_garbage_collect" is reset in vgetc() which is invoked through
* do_exmode() and normal_cmd().
*/
may_garbage_collect = (!cmdwin && !noexmode);
#endif
/*
* If we're invoked as ex, do a round of ex commands.
* Otherwise, get and execute a normal mode command.
*/
if (exmode_active)
{
if (noexmode) /* End of ":global/path/visual" commands */
return;
do_exmode(exmode_active == EXMODE_VIM);
}
else
normal_cmd(&oa, TRUE);
}
cmdwin_result is set to 0 before calling main_loop to handle the cmdwin
window and gets changed when the user causes a command to execute
(either through pressing <CR> or <C-c>). This means that when the
cmdwin isn't active OR the user is still editing their command,
main_loop runs and main_loop calls normal_cmd with toplevel true as long
as exmode isn't active.
When the normal mode state was extracted in dae006a9, the conditions for
toplevel and may_garbage_collect were combined. Since toplevel was set
to always ignore cmdwin, the v:count(1) variables were no longer being
updated when a command was prefixed with a count in the cmdwin.
Closes#5404
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.
