Problem: Terminal doesn't detect if the PTY process is suspended or
offer a convenient way for the user to resume the process.
Solution: Detect suspended PTY process on SIGCHLD and show virtual text
"[Process suspended]" at the bottom-left. Resume the process
when the user presses a key.
Problem: Unexpected behavior after PTY child process fails to chdir(),
as it then thinks it's the parent process.
Solution: Exit the child process instead of returning.
Problem:
Calling os_chdir() to change the child processes' CWD may cause some
unnecessary UI events to be buffered. These UI events don't go anywhere
as execvp() is called before flushing the UI buffer.
Solution:
Use uv_chdir() instead of os_chdir(). Also fix getting error string
incorrectly. Add test for the current behavior.
Using uv_pipe_t to read from PTY master may drop data if the PTY process
exits immediately after output, as libuv treats a partial read after
POLLHUP as EOF, which isn't true for PTY master on Linux. Therefore use
uv_poll_t instead.
This commit can be reverted if libuv/libuv#4992 is fixed for uv_pipe_t.
Problem:
Tests that trigger `os_delay` messages may take 1-3 seconds, wasting
build/CI time, since this serves no purpose in tests.
Solution:
- Introduce `msg_delay` for cases where `os_delay` is being used as
a "UI feature".
- Skip `msg_delay` in tests.
Problem: Windows: Vim always adds the current directory to search path.
This should only happen when using cmd.exe as 'shell'. For
example, powershell won't run binaries from the current
directory.
Solution: Only add current directory to system path, when using cmd.exe
as 'shell'.

Initial support for compiling on haiku os. Some deps can be pulled from
haiku repos, some need to be compiled with nvim's dep build system:
cmake -DUSE_BUNDLED_LIBUV=OFF -DUSE_BUNDLED_UNIBILIUM=OFF -DUSE_BUNDLED_LUAJIT=OFF -B .deps ./cmake.deps
make -C .deps
Problem:
Starting Nvim on MinGW fails:
https://github.com/msys2/MINGW-packages/issues/25140
Unknown system error -1："C:\msys64\ucrt64\bin\nvim.exe"Failed to start Nvim server!
Solution:
On Windows, the main application manifest should use resource ID 1 (RT_MANIFEST).
Update `nvim.rc` to use `1 RT_MANIFEST nvim.manifest` instead of `2`,
ensuring the manifest is correctly embedded and recognized by the system.
ID = 1 is for executable files (.exe)
ID = 2 is for DLLs (/DLL)
From MSVC docs: "Use a value of 2 for a DLL to enable it to specify private dependencies."

Problem:
When running with `--headless --listen ./hello`, pressing Ctrl-C
doesn’t log anything and doesn’t clean up the socket file.
Solution:
handle SIGINT like SIGTERM.
Problem: Old Coverity warning for not checking ftell() return value.
Solution: Check return value of fseek() and ftell().

This fixes the following warning in tests with ASAN or TSAN:
-------- Running tests from test/functional/lua/watch_spec.lua
RUN T4253 vim._watch watch() ignores nonexistent paths: 29.00 ms OK
nvim took 2006 milliseconds to exit after last test
This indicates a likely problem with the test even if it passed!
Problem:
All of Nvim’s threads are clamped to the Default QoS class. This means
that Nvim is forced to compete for CPU time with compilers and other
batch work, and is even prioritized beneath user-initiated work in GUI
apps like e.g. file imports. This significantly harms responsiveness.
Solution:
Tell the kernel that the Nvim process takes part in rendering a UI.
Implementation:
Remove the process-wide QoS clamp. This doesn’t directly do anything to
the main thread, but rather has the side-effect of letting the main
thread run at its actual QoS (User Interactive QoS).
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.
Using the preprocessor before generating prototypes provides some
"niceties" but the places that rely on these are pretty few.
Vastly simplifying the BUILD SYSTEM is a better trade-off.
Unbalancing { } blocks due to the preprocessor is cringe anyway (think
of the tree-sitter trees!), write these in a different way.
Add some workarounds for plattform specific features.
INCLUDE_GENERATED_DECLARATIONS flag is now technically redundant,
but will be cleaned up in a follow-up PR as it is a big mess.
Problem:
- The VIM_VERSION_NODOT macro maintained support for legacy Vim
version-specific runtime directories (e.g., "vim82") which I believe
have never been relevant for Neovim
Solution:
- Remove it
- Rename `vim_version_dir()` to `vim_runtime_dir()`
Problem: On Windows, the value of `term` is overwritten without freeing
the old allocated value, which may lead to a memory leak.
GCC also gives a "incompatible pointer type" warning about
passing `*term` to os_tty_guess_term().
Solution: Don't override the old allocated value, and copy the guessed
value to `term` if its old value is NULL.
Problem: too many strlen() calls
Solution: Change expand_env() to return string length
(John Marriott)
This commit does the following changes:
- In expand_env_esc():
- return the length of the returned dst string.
- refactor to remove some calls to STRLEN() and STRCAT()
- add check for out-of-memory condition.
- Change call sites in various source files to use the return value

Problem: Two separate window messages are used to get
the original console icon and set a new
one on windows, although the `WM_SETICON`
message returns the original icon itself.
Solution: Replace the two `WM_GETICON` messages with
two `WM_SETICON` messages, save the return
values and remove the call to `os_icon_set`.
Also, replace `os_icon_set` with `os_icon_reset`
as its only usage is now resetting the
icon to the original one.
Problem: When using conhost and pressing the 'x' button
to close it while nvim is open, nvim hangs up
while trying to reset the window icon, causing a big
delay before the terminal actually closes. #34171
Solution: Set the window handle to NULL after receiving SIGHUP
so that nvim will not try resetting the icon.
Problem:
stderr messages from executing ":!cmd" show up with
highlight hl-ErrorMsg. But some shell utilites use stderr for debug
logging, progress updates, etc.
Solution:
Highlight shell command outputs hl-StderrMsg and hl-StdoutMsg.
NEW BUILD SYSTEM!
This is a MVP implementation which supports building the "nvim" binary,
including cross-compilation for some targets.
As an example, you can build a aarch64-macos binary from
an x86-64-linux-gnu host, or vice versa
Add CI target for build.zig currently for functionaltests on linux
x86_64 only
Follow up items:
- praxis for version and dependency bumping
- windows 💀
- full integration of libintl and gettext (or a desicion not to)
- update help and API metadata files
- installation into a $PREFIX
- more tests and linters
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.
Problem:
Upon receiving a deadly signal, Nvim doesn't write buffers even if
the option 'autowriteall' is set.
Solution:
Write to all writable buffers upon SIGHUP or SIGQUIT (but not
SIGTERM), if the option 'autowriteall' is set.

Problem:
On Windows, the first attempt at finishing up after a terminal process
terminates is delayed by 200ms, even if it would be possible to finish
up immediately.
Solution:
Make the first attempt at finishing up immediately after the process
terminates.
Problem: too many strlen() calls in os_unix.c
Solution: refactor os_unix.c and remove calls to strlen()

Omit os_expand_wildcards() change: Nvim's code is more complicated and

The newer UCRT runtime has native support for UTF-8, including forcing
it as the active codepage even before `main()` is called. This means
the c runtime will properly convert windows WCHAR:s into UTF-8 bytes,
as early as the argv/argc params to `main()` . Whereas MSVCRT does not
support this reliably and required us to use `wmain()`.
Only MSVC supports using manifest files directly as source files.
The solution for other Windows toolchains is to use a .rc file.
Problem: Highlight group id is not propagated to the end of the message call
stack, where ext_messages are emitted.
Solution: Refactor message functions to pass along highlight group id
instead of attr id.
