These are not needed after #35129 but making uncrustify still play nice
with them was a bit tricky.
Unfortunately `uncrustify --update-config-with-doc` breaks strings
with backslashes. This issue has been reported upstream,
and in the meanwhile auto-update on every single run has been disabled.
Problem: completion: various flaws in fuzzy completion
Solution: fix the issues (Girish Palya)
- Remove the brittle `qsort()` on `compl_match_array`.
- Add a stable, non-recursive `mergesort` for the internal doubly
linked list of matches.
- The sort now happens directly on the internal representation (`compl_T`),
preserving sync with external structures and making sorting stable.
- Update fuzzy match logic to enforce `max_matches` limits after
sorting.
- Remove `trim_compl_match_array()`, which is no longer necessary.
- Fixe test failures by correctly setting `selected` index and
maintaining match consistency.
- Introduce `mergesort_list()` in `misc2.c`, which operates generically
over doubly linked lists.
- Remove `pum_score` and `pum_idx` variables

Problem:
vim.uv.os_setenv gets "stuck" per-key. #32550
Caused by the internal `envmap` cache. #7920
:echo $FOO <-- prints nothing
:lua vim.uv.os_setenv("FOO", "bar")
:echo $FOO <-- prints bar (as expected)
:lua vim.uv.os_setenv("FOO", "fizz")
:echo $FOO <-- prints bar, still (not expected. Should be "fizz")
:lua vim.uv.os_unsetenv("FOO")
:echo $FOO <-- prints bar, still (not expected. Should be nothing)
:lua vim.uv.os_setenv("FOO", "buzz")
:echo $FOO <-- prints bar, still (not expected. Should be "buzz")
Solution:
- Remove the `envmap` cache.
- Callers to `os_getenv` must free the result.
- Update all call-sites.
- Introduce `os_getenv_noalloc`.
- Extend `os_env_exists()` the `nonempty` parameter.
Since paste data is handled via a separate channel, the data processed via `input_buffer` is typically just explicit keys as typed in by the user. Therefore it should be fine to use `memmove()` to always put the remaining data in front when refilling the buffer.
Problem: Using xstrlcpy() when the exact length of the string to be
copied is known is not ideal because it requires adding 1 to
the length and an unnecessary strlen().
Solution: Add xmemcpyz() and use it in place of such xstrlcpy() calls.
Before, we needed to always pack an entire msgpack_rpc Object to
a continous memory buffer before sending it out to a channel.
But this is generally wasteful. it is better to just flush
whatever is in the buffer and then continue packing to a new buffer.
This is also done for the UI event packer where there are some extra logic
to "finish" of an existing batch of nevents/ncalls. This doesn't really
stop us from flushing the buffer, just that we need to update the state
machine accordingly so the next call to prepare_call() always will
start with a new event (even though the buffer might contain overflow
data from a large event).
The way ml_replace_buf is implemented makes it unfriendly for
being used in a loop: every call allocates a scratch buffer for putting
the line into the "dirty" state. This then immediately needs to be freed
as the next ml_replace_buf and/or ml_append_buf call will flush that buffer.
It's better to later pay the price of allocating the scratch buffer only if
the line is being immediately edited (likely when using the API to only
change one line) with an extra memcpy, than allocating that buffer
multiple times every time the API is called.
Of course, a separate xmalloc/xfree cycle for each time the dirty line
changes is unwanted to begin with. But fixing that is a later refactor.
Attempting to manipulate the window layout via ex commands is not safe
here. It is also redundant: `win_free_all()` can free multiple windows
by itself perfectly fine.
Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
Problem: We have `P_(BOOL|NUM|STRING)` macros to represent an option's type, which is redundant because `OptValType` can already do that. The current implementation of option type flags is also too limited to allow adding multitype options in the future.
Solution: Remove `P_(BOOL|NUM|STRING)` and replace it with a new `type_flags` attribute in `vimoption_T`. Also do some groundwork for adding multitype options in the future.
Side-effects: Attempting to set an invalid keycode option (e.g. `set t_foo=123`) no longer gives an error.
This reverts commit fe30d8ccef.
The original commit intends to prevent heap-use-after-free with EXITFREE
caused by changedtick_di, which is no longer a problem.
Freeing buffers after freeing variables will cause heap-use-after-free
with EXITFREE when a partial is used as prompt callback.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
The 'arabicshape' feature of vim is a transformation of unicode text to
make arabic and some related scripts look better at display time. In
particular the content of a cell will be adjusted depending on the
(original) content of the cells just before and after it.
This is implemented by the arabic_shape() function in nvim. Before this
commit, shaping was invoked in four different contexts:
- when rendering buffer text in win_line()
- in line_putchar() for rendering virtual text
- as part of grid_line_puts, used by messages and statuslines and
similar
- as part of draw_cmdline() for drawing the cmdline
This replaces all these with a post-processing step in grid_put_linebuf(),
which has become the entry point for all text rendering after recent
refactors.
An aim of this is to make the handling of multibyte text yet simpler.
One of the main reasons multibyte chars needs to be "parsed" into
codepoint arrays of composing chars is so that these could be inspected
for the purpose of shaping. This can likely be vastly simplified in many
contexts where only the total length (in bytes) and width of composed
char is needed.
- Move vimoption_T to option.h
- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h
- option_defs.h and option_vars.h don't include each other
This reduces the total number of khash_t instantiations from 22 to 8.
Make the khash internal functions take the size of values as a runtime
parameter. This is abstracted with typesafe Map containers which
are still specialized for both key, value type.
Introduce `Set(key)` type for when there is no value.
Refactor shada.c to use Map/Set instead of khash directly.
This requires `map_ref` operation to be more flexible.
Return pointers to both key and value, plus an indicator for new_item.
As a bonus, `map_key` is now redundant.
Instead of Map(cstr_t, FileMarks), use a pointer map as the FileMarks struct is
humongous.
Make `event_strings` actually work like an intern pool instead of wtf it
was doing before.
Problem: Alloc/free of buffer for each quickfix entry is inefficient.
Solution: Use a shared grow array. (Yegappan Lakshmanan, closesvim/vim#11365)

Problem:
1. Some calls to preserve_exit() don't put a message in IObuff, so the
IObuff printed by preserve_exit() contains unrelated information.
2. If a TUI client runs out of memory or receives a deadly signal, the
error message is shown on alternate screen and cannot be easily seen
because the TUI exits alternate screen soon afterwards.
Solution:
Pass error message to preserve_exit() and exit alternate screen before
printing it.
Note that this doesn't fix the problem that server error messages cannot
be easily seen on exit. This is tracked in #21608 and #21843.
- The defined interface for the UI is only the RPC protocol. The original
UI interface as an array of function pointers fill no function.
- On the server, all the UI:s are all RPC channels.
- ui.c is only used on the server.
- The compositor is a preprocessing step for single-grid UI:s
- on the client, ui_client and tui talk directly to each other
- we still do module separation, as ui_client.c could form the basis
of a libnvim client module later.
Items for later PR:s
- vim.ui_attach is still an unhappy child, reconsider based on plugin experience.
- the flags in ui_events.in.h are still a mess. Can be simplified now.
- UX for remote attachment needs more work.
- startup for client can be simplified further (think of the millisecs we can save)
Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return
warnings, but don't enable them. While the warnings can be useful, they
are in general too noisy to enable.
all pointers returned by arena_alloc residing in arena block should be
properly aligned
to meet neovim's alignment requirements but keeping it simple settle on
ARENA_ALIGN = MAX(sizeof(void *), sizeof(double)).
