Problem: fnamemodify() treats ".." and "../" differently.
Solution: Expand ".." properly like how "/.." is treated in 8.2.3388.

Problem: fnamemodify('path/..', ':p') differs from using 'path/../'.
Solution: Include the "/.." in the directory name. (closesvim/vim#8808)

The latter was mostly relevant with the past char_u madness.
NOTE: STRCAT also functioned as a counterfeit "NOLINT" for clint
apparently. But NOLINT-ing every usecase is just the same as disabling
the check entirely.
Use uv_fs_realpath() instead.
It seems that uv_fs_realpath() has some problems on non-Linux platforms:
- macOS and other BSDs: this function will fail with UV_ELOOP if more
than 32 symlinks are found while resolving the given path. This limit
is hardcoded and cannot be sidestepped.
- Windows: while this function works in the common case, there are a
number of corner cases where it doesn't:
- Paths in ramdisk volumes created by tools which sidestep the Volume
Manager (such as ImDisk) cannot be resolved.
- Inconsistent casing when using drive letters.
- Resolved path bypasses subst'd drives.
Ref: https://docs.libuv.org/en/v1.x/fs.html#c.uv_fs_realpath
I don't know if the old implementation that uses uv_chdir() and uv_cwd()
also suffers from the same problems.
- For the ELOOP case, chdir() seems to have the same limitations.
- On Windows, Vim doesn't use anything like chdir() either. It uses
_wfullpath(), while libuv uses GetFinalPathNameByHandleW().
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.
If the filename passed to vim_FullName() is a relative directory, and
does not exist, it is appended to the current working directory. Since
the return value of append_path() was ignored, and if the buffer length
was too small to fit getcwd() + dirname(filename), it would still try to
append the basename(filename).
This was manifesting as a failure in test/unit/path_spec.lua in:
itp('fails and uses filename if given filename contains non-existing directory', ..
This failure occurs when running the tests from directory with a short
path such as: /work/src/nv
test/unit/path_spec.lua:420: Expected objects to be the same.
Passed in:
(string) '/work/src/nv/test.file'
Expected:
(string) 'non_existing_dir/test.file'
This return value for the second call to append_path() to append
basename(filename) was checked, and this is where it would fail for
normal / longer getcwd()s.
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: Many places in the code use `findoption()` to access an option using its name, even if the option index is available. This is very slow because it requires looping through the options array over and over.
Solution: Use option index instead of name wherever possible. Also introduce an `OptIndex` enum which contains the index for every option as enum constants, this eliminates the need to pass static option names as strings.
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.
- 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
Problem: Bashslashes added as regexp in runtime completion may be
treated as path separator with some 'isfname' value.
Solution: Make curly braces work for runtime completion and use it.
Problem:
nvim_parse_cmd() in pcall() may show an error message (side-effect):
:lua pcall(vim.api.nvim_parse_cmd, vim.fn.getcmdline(), {})
E16: Invalid range
Solution:
Avoid emsg() in the nvim_parse_cmd() codepath.
- refactor(api): add error message output parameter to get_address()
- fix: null check emsg() parameter
- refactor: remove emsg_off workaround from do_incsearch_highlighting()
- refactor: remove emsg_off workaround from cmdpreview_may_show()
- refactor: remove remaining calls to emsg() from parse_cmd_address() and get_address()
- (refactor): lint set_cmd_dflall_range()
- refactor: addr_error() - move output parameter to return value
Fix#20339
TODO:
These are the functions called by `get_address()`:
```
nvim_parse_cmd() -> parse_cmdline() -> parse_cmd_address() -> get_address()
skipwhite()
addr_error()
qf_get_cur_idx()
qf_get_cur_valid_idx()
qf_get_size()
qf_get_valid_size()
mark_get()
mark_check()
assert()
skip_regexp()
magic_isset()
> do_search()
> searchit()
ascii_isdigit()
getdigits()
getdigits_int32()
compute_buffer_local_count()
hasFolding()
```
From these functions, I found at least two that call emsg directly:
- do_search()
- seems to be simple to refactor
- searchit()
- will be more challenging because it may generate multiple error messages,
which can't be handled by the current `errormsg` out-parameter.
For example, it makes multiple calls to `vim_regexec_multi()` in a loop that
possibly generate error messages, and later `searchit()` itself may generate
another one:
- c194acbfc4/src/nvim/search.c (L631-L647)
- c194acbfc4/src/nvim/search.c (L939-L954)

problem: breakcheck might run arbitrary lua code, which might require
modules and thus invoke runtime path calculation recursively.
solution: Block the use of breakcheck when expanding glob patterns
inside 'runtimepath'

Problem: Cannot use an import in 'includeexpr'.
Solution: Set the script context when evaluating 'includeexpr'
