Problem: CI reports leaks in libgtk3 library
Solution: Add libgtk-3 library to leak suppression
Recently, CI started reporting leaks inside the GTK3 library, which cause
failures like here
https://github.com/vim/vim/actions/runs/16796766276/job/47572520887?pr=17922
So let's add libgtk-3*.so* to the leak suppression for the
gtk_init_check() function.

And anticipate occasional multibyte line wrapping owing to:

> spurious U+FFFD (0xEF 0xBF 0xBD) characters claim more columns than
> are available (75) and then invalidate line correspondence under test.
Observe that for "vim_ex_command.vim" another workaround is
chosen: the long line containing an only multibyte character
near its EOL is conversely made longer by padding and moving
the character to a separate _tail_ part of the wrapped line.
That is, the _head_ part of the line is all ASCII characters
and the wrapped _tail_ part is a mix of various characters
whose total byte count is within bounds.

As reported in #16559, bytes of a multibyte character may
be written as separate U+FFFD characters in a ":terminal"
window on a busy machine. The testing facilities currently
offer an optional filtering step to be carried out between
reading and comparing the contents of two screendump files
for each such file. This filtering has been resorted to
(#14767 and #16560) in an attempt to unconditionally replace
known non-Latin-1 characters with an arbitrary substitute
ASCII character and avoid this rendering mishap leading to
syntax tests failures. However, it has been overlooked at
the time that metadata description (in shorthand) to follow
spurious U+FFFD characters may be *distinct* and make the
remainder of such a line, ASCII characters and whatnot, also
unequal between compared screendump files.
While it is straightforward to adapt current filter files to
ignore the line characters after the leftmost U+FFFD,
> It is challenging and error-prone to keep up to date filter
> files because moving around examples in source files will
> likely make redundant some previously required filter files
> and, at the same time, it may require creating new filter
> files for the same source file; substituting one multibyte
> character for another multibyte character will also demand
> a coordinated change for filter files.
Besides, unconditionally dropping arbitrary parts of a line
is rather too blunt an instrument. An alternative approach
is to not use the supported filtering for this purpose; let
a syntax test pass or fail initially; then *if* the same
failure is imminent, drop the leftmost U+FFFD and the rest
of the previously seen line (repeating it for all previously
seen unequal lines) before another round of file contents
comparing. The obvious disadvantage with this filtering,
unconditional and otherwise, is that if there are consistent
failures for _other reasons_ and the unequal parts happen to
be after U+FFFDs, then spurious test passing can happen when
stars align for _a particular test runner_.
Hence syntax test authors should strive to write as little
significant text after multibyte characters as syntactically
permissible, write multibyte characters closer to EOL in
general, and make sure that their checked-in and published
"*.dump" files do not have any U+FFFDs.
It is also practical to refrain from attempting screendump
generation if U+FFFDs can already be discovered, and instead
try re-running from scratch the syntax test in hand, while
accepting other recently generated screendumps without going
through with new rounds of verification.

Before two screendumps are compared for equality by calling
"VerifyScreenDump()", parts of their contents can be omitted
from comparison by executing arbitrary Vim commands written
in a filter file that shares its basename with screendumps.
Sometimes, such filtering can only be too general, as more
context is required in order to decide what parts to touch.
Two new arbitrary functions are therefore hooked in the body
of "VerifyScreenDump()" for the purpose of probing into the
current context and applying iterative filtering as needed.
A paired-up public implementation of each function is also
provided to expedite a workaround for #16559:
------------------------------------------------------------
source util/screendump.vim
let opts = {
\ 'FileComparisonPreAction':
\ function('g:ScreenDumpDiscardFFFDChars'),
\ 'NonEqualLineComparisonPostAction':
\ function('g:ScreenDumpLookForFFFDChars'),
\ }
call g:VerifyScreenDump(buf, basename, opts)

Problem: cannot perform autocompletion
Solution: Add the 'autocomplete' option value
(Girish Palya)
This change introduces the 'autocomplete' ('ac') boolean option to
enable automatic popup menu completion during insert mode. When enabled,
Vim shows a completion menu as you type, similar to pressing |i\_CTRL-N|
manually. The items are collected from sources defined in the
'complete' option.
To ensure responsiveness, this feature uses a time-sliced strategy:
- Sources earlier in the 'complete' list are given more time.
- If a source exceeds its allocated timeout, it is interrupted.
- The next source is then started with a reduced timeout (exponentially
decayed).
- A small minimum ensures every source still gets a brief chance to
contribute.
The feature is fully compatible with other |i_CTRL-X| completion modes,
which can temporarily suspend automatic completion when triggered.
See :help 'autocomplete' and :help ins-autocompletion for more details.
To try it out, use :set ac
You should see a popup menu appear automatically with suggestions. This
works seamlessly across:
- Large files (multi-gigabyte size)
- Massive codebases (:argadd thousands of .c or .h files)
- Large dictionaries via the `k` option
- Slow or blocking LSP servers or user-defined 'completefunc'
Despite potential slowness in sources, the menu remains fast,
responsive, and useful.
Compatibility: This mode is fully compatible with existing completion
methods. You can still invoke any CTRL-X based completion (e.g.,
CTRL-X CTRL-F for filenames) at any time (CTRL-X temporarily
suspends 'autocomplete'). To specifically use i_CTRL-N, dismiss the
current popup by pressing CTRL-E first.
---
How it works
To keep completion snappy under all conditions, autocompletion uses a
decaying time-sliced algorithm:
- Starts with an initial timeout (80ms).
- If a source does not complete within the timeout, it's interrupted and
the timeout is halved for the next source.
- This continues recursively until a minimum timeout (5ms) is reached.
- All sources are given a chance, but slower ones are de-prioritized
quickly.
Most of the time, matches are computed well within the initial window.
---
Implementation details
- Completion logic is mostly triggered in `edit.c` and handled in
insexpand.c.
- Uses existing inc_compl_check_keys() mechanism, so no new polling
hooks are needed.
- The completion system already checks for user input periodically; it
now also checks for timer expiry.
---
Design notes
- The menu doesn't continuously update after it's shown to prevent
visual distraction (due to resizing) and ensure the internal list
stays synchronized with the displayed menu.
- The 'complete' option determines priority—sources listed earlier get
more time.
- The exponential time-decay mechanism prevents indefinite collection,
contributing to low CPU usage and a minimal memory footprint.
- Timeout values are intentionally not configurable—this system is
optimized to "just work" out of the box. If autocompletion feels slow,
it typically indicates a deeper performance bottleneck (e.g., a slow
custom function not using `complete_check()`) rather than a
configuration issue.
---
Performance
Based on testing, the total roundtrip time for completion is generally
under 200ms. For common usage, it often responds in under 50ms on an
average laptop, which falls within the "feels instantaneous" category
(sub-100ms) for perceived user experience.
| Upper Bound (ms) | Perceived UX
|----------------- |-------------
| <100 ms | Excellent; instantaneous
| <200 ms | Good; snappy
| >300 ms | Noticeable lag
| >500 ms | Sluggish/Broken
---
Why this belongs in core:
- Minimal and focused implementation, tightly integrated with existing
Insert-mode completion logic.
- Zero reliance on autocommands and external scripting.
- Makes full use of Vim’s highly composable 'complete' infrastructure
while avoiding the complexity of plugin-based solutions.
- Gives users C native autocompletion with excellent responsiveness and
no configuration overhead.
- Adds a key UX functionality in a simple, performant, and Vim-like way.
