Problem: using int as bool
Solution: refactor: use bool type for internal flags in buf_T
(Hirohito Higashi)
Change the type of 23 internal state flag fields in buf_T from int
to bool for improved type clarity and code readability.
These fields are pure boolean flags that are never accessed via the
option system's varp (which uses *(int *)varp = value), never compared
with int fields holding non-0/1 values, and never use tristate values.
Converted fields:
- State flags: b_dev_valid, b_saving, b_mod_set, b_new_change,
b_marks_read, b_modified_was_set, b_did_filetype, b_keep_filetype,
b_au_did_filetype, b_u_synced, b_scanned, b_p_initialized
- Characteristic flags: b_has_textprop, b_may_swap, b_did_warn,
b_help, b_spell, b_shortname, b_has_sign_column, b_netbeans_file,
b_was_netbeans_file, b_write_to_channel, b_diff_failed
All TRUE/FALSE assignments to these fields have been updated to
true/false accordingly. The type of temporary save variables
(e.g. help_save in tag.c) has also been adjusted to bool.
Option value fields (b_p_XXX) are kept as int because they are
accessed via the option system and some use tristate (-1) semantics.
Fields compared with int option values (b_start_eof, b_start_eol,
b_start_bomb) are also kept as int to preserve comparison integrity.

Problem: Reading a crafted viminfo file can cause a heap buffer
overflow because the length value from getdigits() is cast to
int, truncating large size_t values
Solution: Remove the (int) cast when calling alloc() (sentinel404)

Problem: using copy_option_part() can be improved
Solution: Refactor and use the return value of copy_option_part() to
avoid strlen() calls (John Marriott).
In addition, this commit includes the following changes:
memline.c:
- In recover_names():
- Replace calls to vim_strsave() with vim_strnsave() for the literal
strings
- Use a string_T to store local variable dir_name.
bufwrite.c:
- In buf_write()
- move variable wp to where it is used.
help.c:
- In fix_help_buffer():
- replace call to add_pathsep() with after_pathsep()
optionstr.c:
- In export_myvimdir():
- use a string_T to store local variable buf
- replace call to add_pathsep() with after_pathsep()
scriptfile.c:
- In do_in_path():
- use a string_T to store local variable buf
- measure the lengths of prefix and name once before the while loop
- replace call to add_pathsep() with after_pathsep()
- move some variables closer to where they are used
spellfile.c:
- In init_spellfile():
- use a string_T to store local variable buf

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: is*() and to*() function may be unsafe
Solution: Add SAFE_* macros and start using those instead
(Keith Thompson)
Use SAFE_() macros for is*() and to*() functions
The standard is*() and to*() functions declared in <ctype.h> have
undefined behavior for negative arguments other than EOF. If plain char
is signed, passing an unchecked value from argv for from user input
to one of these functions has undefined behavior.
Solution: Add SAFE_*() macros that cast the argument to unsigned char.
Most implementations behave sanely for negative arguments, and most
character values in practice are non-negative, but it's still best
to avoid undefined behavior.
The change from #13347 has been omitted, as this has already been
separately fixed in commit ac709e2fc0

Problem: Vim9: No support for type aliases
Solution: Implement :type command
A type definition is giving a name to a type specification. This also known
type alias.
:type ListOfStrings = list<string>
The type alias can be used wherever a built-in type can be used. The type
alias name must start with an upper case character.

Problem: Keeping track of allocated lines in user functions is too
complicated.
Solution: Instead of freeing individual lines keep them all until the end.
Problem: Some tests fail on Cirrus CI and/or with FreeBSD.
Solution: Make 'backupskip' empty. Do not run tests as root. Check for
directory when using viminfo. (Ozaki Kiichi, closes#6596)
Problem: After deleting a file mark it is still in viminfo.
Solution: When a file mark was deleted more recently than the mark in the
merged viminfo file was updated, do not store the mark. (Pavol
Juhas, closes#5401, closes#1339)
Problem: The "last used" info of a buffer is under used.
Solution: Add "lastused" to getbufinfo(). List buffers sorted by last-used
field. (Andi Massimino, closes#4722)
