Problem: unlike win_close, win_close_othertab could be used to close the
autocommand window from a different tabpage. This causes aucmd_restbuf to close
the wrong window, potentially causing a crash.
Solution: disallow closing it. Also replace a deprecated use of exc_exec in the
test file.
Fixes#21409.
Problem: empty comma-separated patterns in an aupat aren't skipped correctly.
Solution: skip consecutive commas in an aupat.
Also simplify the logic.
(cherry picked from commit 1cde71233f)
Problem: patterns after a buffer-local pattern in a comma-separated aupat are
ignored.
Solution: ensure pat refers to the original buffer after each pattern, not the
buflocal_pat buffer, and when printing make sure it's normalized for
each pattern, not just the first.
Also simplify the logic when printing all autocommands for an event, and ensure
headings aren't repeated for each event when printing autocommands.
(cherry picked from commit 6d2330f50d)
Problem: use-after-free in win_move_after if win_enter autocommands free win1/2.
Solution: set w_pos_changed before calling win_enter.
(cherry picked from commit d1189ea508, also adding
an import of "exec" in the test)
Problem:
Event handler declared with `once=true` can re-trigger itself (i.e. more
than once!) by calling `nvim_exec_autocmds` or `:doautocmd`.
Analysis:
This happens because the callback is executed before deletion/cleanup
(`aucmd_del`). And calling `aucmd_del` before `call_autocmd_callback`
breaks the autocmd execution...
Solution:
Set `ac->pat=NULL` to temporarily "delete" the autocmd, then restore it
after executing the callback.
Fix#25526

Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
This is the command invoked repeatedly to make the changes:
:%s/^\(.*\)|\%(\*\(\d\+\)\)\?$\n\1|\%(\*\(\d\+\)\)\?$/\=submatch(1)..'|*'..(max([str2nr(submatch(2)),1])+max([str2nr(submatch(3)),1]))/g
Instead of nested linked lists, store autocommands in a flat, contiguous
kvec_t, with one kvec_t per event type. Previously patterns were stored
in each node of the outer linked list, so they can be matched only once
on repeating patterns. They are now reference counted and referenced in
each autocommand, and matching is skipped if the pattern repeats. Speeds
up creation and deletion, execution is not affected.

Problem: Autocommand that splits window messes up window layout.
Solution: Disallow splitting a window while closing one. In ":all" give an
error when moving a window will not work.

Expected error number was changed to E242 in Vim in patch 8.2.1183, and
patch 8.2.2420 (which has already been ported) made the test no longer
throw E249 in Vim, so just use E242 in the test.
Nvim uses a floating window for the autocmd window, but in certain situations,
it can be made non-floating (`:wincmd J`), which can cause issues due to the
previous setup and cleanup logic for a non-floating aucmd_win being removed from
aucmd_prepbuf and aucmd_restbuf.
This can cause glitchiness and crashes due to the aucmd_win's frame being
invalid after closing its tabpage, for example.
Ensure aucmd_win cannot be made non-floating. The only place this happens is in
win_split_ins if new_wp != NULL.
- Rename `meth_pcall`.
- Make `pcall_err` raise an error if the function does not fail.
- Add `vim.pesc()` to treat a string as literal where a Lua pattern is
expected.
Unfortunately we cannot indiscriminately replace xfree() with
XFREE_CLEAR(), because comparing pointers after freeing them is a common
pattern. Example in `tv_list_remove_items()`:
xfree(li);
if (li == item2) {
break;
}
Instead we can do it selectively/explicitly.
ref #1375
- redraw! in an invisible buffer rendered the screen unusable.
- storing the autocmd window handle and using it in API function could lead
to crashes. Unregister the handle when the window is not active.
Problem: If autocmd pattern only contained `++once` handlers, and
all of them completed, then there would be an empty group
displayed by `:autocmd Foo`.
Solution: Delete the pattern if all of its commands were deleted.
Adds a new feature to :autocmd which sets the handler to be executed at
most one times.
Before:
augroup FooGroup
autocmd!
autocmd FileType foo call Foo() | autocmd! FooGroup * <buffer>
augroup END
After:
autocmd FileType foo once call Foo()
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.
