Problem: Amiga: no support for AmigaOS 3.x
Solution: Add support for building Vim on classic AmigaOS 3.x with the
bebbo cross-compiler and libnix (-noixemul) runtime
(Duncan Bowring).
The existing Make_ami.mak targets AmigaOS 4 (clib2), AROS, and MorphOS.
This patch adds a fourth target for classic 68k AmigaOS 3.x systems
(A1200, A4000, accelerated A500/A2000) using:
```
make -f Make_ami.mak UNM=AmigaOS3 BUILD=normal
```
Changes:
os_amiga.c:
- Add 256 KiB __stack cookie for OS3 (conservative for limited RAM)
- Add safe_Lock() wrapper to suppress "Please insert volume" system
requesters during path probing (benefits all Amiga targets)
- Suppress system requesters globally in mch_init() via pr_WindowPtr=-1
(Vim probes many paths at startup; Lock()/Open() on non-existent
volume names triggers blocking system requesters)
- Fix mch_get_host_name() for OS3 (libnix has no gethostname)
- Fix Delay() prototype for non-LATTICE compilers
- Fix nilfh file handle leak on error exit in mch_check_win()
os_amiga.h:
- Add fchown/fchmod/ftruncate no-op stubs for OS3/libnix
os_amiga_stubs.c (new):
- IM function stubs (referenced by optiondefs.h, no X11 on Amiga)
- mch_rmdir() via AmigaDOS DeleteFile()
- getpwuid()/getgrgid()/getuid() stubs (single-user system)
Make_ami.mak:
- Add AmigaOS3 target with -noixemul, -std=gnu99, -DWORDS_BIGENDIAN
blowfish.c:
- Accept WORDS_BIGENDIAN or AMIGA without requiring HAVE_CONFIG_H
xdiff/xmacros.h:
- Make SIZE_MAX fallback unconditional (not just hpux/VMS)
All OS3-specific changes are guarded by:
#if defined(__GNUC__) && defined(AMIGA) && !defined(__amigaos4__)
Tested on FS-UAE with Workbench 3.1: 23 automated tests passing.
Binary size: 2.2 MiB with -Os -m68020 -DFEAT_NORMAL.
This is the first modern Vim build for classic 68k AmigaOS since
Vim 5.8 circa 1998. Vim was originally released on the Amiga
(Fred Fish Disk 591, 1991).

Problem: GTK: gdk_pixbuf_new_from_xpm_data() is deprecated since
2.44.5, causing build warnings
Solution: Replace XPM icon loading with PNG byte arrays loaded via
g_memory_input_stream_new_from_data() and
gdk_pixbuf_new_from_stream(). These APIs are available since
GLib 2.12 and gdk-pixbuf 2.14 (around 2008) so should be safe
to use today.

Problem: memline: a crafted swap files with bogus pe_page_count/pe_bnum
values could cause a multi-GB allocation via mf_get(), and
invalid pe_old_lnum/pe_line_count values could cause a SEGV
when passed to readfile() (ehdgks0627, un3xploitable)
Solution: Add bounds checks on pe_page_count and pe_bnum against
mf_blocknr_max before descending into the block tree, and
validate pe_old_lnum >= 1 and pe_line_count > 0 before calling
readfile().

Problem: crypt: Crash when reading an encrypted UTF-8 file.
This happens because readfile() does not account for leftover

Solution: Include conv_restlen in the offset calculations and memmove
operations within readfile() (Foxe Chen).

Problem: Wayland code can be improved
Solution: Refactor Wayland Clipboard code (Foxe Chen).
This the second attempt to refactor the Wayland code base:
- Move clipboard code from wayland.c to clipboard.c
- Use C99 bool type
- Properly poll the Wayland display file descriptor
- Instead of checking if the data source is not NULL in order to
determine if a selection event comes from us, use a special mime type
to identify selection events coming from ourselves. The problem with
the previous approach is that race conditions may occur.
- Put the focus stealing code under a new feature "wayland_focus_steal"
- Use ELAPSED_* macros instead of gettimeofday()
- Pass tests
- Reimplement commented out code
- Update docs
- Make Wayland clipboard behaviour more in line with X11 when connection
is lost
- add missing malloc checks and possible memory leaks + refactored some
tests.

Problem: fuzzy-matching can be improved
Solution: Implement a better fuzzy matching algorithm
(Girish Palya)
Replace fuzzy matching algorithm with improved fzy-based implementation
The
[current](https://www.forrestthewoods.com/blog/reverse_engineering_sublime_texts_fuzzy_match/)
fuzzy matching algorithm has several accuracy issues:
* It struggles with CamelCase
* It fails to prioritize matches at the beginning of strings, often
ranking middle matches higher.
After evaluating alternatives (see my comments
[here](https://github.com/vim/vim/issues/17531#issuecomment-3112046897)
and
[here](https://github.com/vim/vim/issues/17531#issuecomment-3121593900)),
I chose to adopt the [fzy](https://github.com/jhawthorn/fzy) algorithm,
which:
* Resolves the aforementioned issues.
* Performs better.
Implementation details
This version is based on the original fzy
[algorithm](https://github.com/jhawthorn/fzy/blob/master/src/match.c),
with one key enhancement: **multibyte character support**.
* The original implementation supports only ASCII.
* This patch replaces ascii lookup tables with function calls, making it
compatible with multibyte character sets.
* Core logic (`match_row()` and `match_positions()`) remains faithful to
the original, but now operates on codepoints rather than single-byte
characters.
Performance
Tested against a dataset of **90,000 Linux kernel filenames**. Results
(in milliseconds) show a **\~2x performance improvement** over the
current fuzzy matching algorithm.

A tar archive containing files with leading `/` may cause confusions as
to where the content is extracted. Let's make sure we drop the leading
`/` and use a relative path instead.
Also while at it, had to refactor it quite a bit and increase the

In this commit, all legacy encodings for tutor files are removed.
* All the tutor files `tutor1.xx` and `tutor2.xx` are now `utf-8`
* All `README.xx.txt` files are now `utf-8`
* All makefiles are removed, as they are no longer needed
* The `tutor.vim` script is simplified
* The `README` indicates `utf-8` as a requirement
* update vimtutor.bat file
In 2025, there is no realistic scenario where a beginner starts the Vim
9.1 tutor on a machine that lacks UTF-8 support.
This change will ease the maintenance of the tutor files. Cf #17562 for

Vim tests for features such as python3 relies on checking the feature
flag exists by doing `has('python3')`. However, if the feature itself is
broken and the flag returns 0, the relevant tests will simply silently
get ignored and CI will passed erroneously. As a preventive measure, as
basic checks to make sure certain feature flags are correct as a basic
smoke test.
Currently only checking two types of feature flags:
1. Features that depend on system packages being installed properly
(e.g. sodium) and could be erroneously dropped if the CI environment
changed or a bug exists in the configure script.
2. Scripting languages. When in dynamic mode, these feature flags (e.g.
"ruby", "python3") will return 0 when the lib cannot be found or the
code has an initialization bug. This happened in #16964 where CI
still passed despite Python 3 being broken.
