This was due to commit 57fc920 ("Socket: Created control socket & pid file
directories.").
This happened because this commit introduced the usage of
nxt_fs_mkdir_parent() in core code which uses nxt_fs_mkdir(), both of
these are defined in src/nxt_fs.c. It turns out however that this file
doesn't get built on MacOS (or any system that isn't Linux or that
lacks a FreeBSD compatible nmount(2) system call) due to the following
In auto/sources we have
if [ $NXT_HAVE_ROOTFS = YES ]; then
NXT_LIB_SRCS="$NXT_LIB_SRCS src/nxt_fs.c"
fi
NXT_HAVE_ROOTFS is set in auto/isolation
If [ $NXT_HAVE_MOUNT = YES -a $NXT_HAVE_UNMOUNT = YES ]; then
NXT_HAVE_ROOTFS=YES
cat << END >> $NXT_AUTO_CONFIG_H
#ifndef NXT_HAVE_ISOLATION_ROOTFS
#define NXT_HAVE_ISOLATION_ROOTFS 1
#endif
END
fi
While we do have a check for a generic umount(2) which is found on
MacOS, for mount(2) we currently only check for the Linux mount(2) and
FreeBSD nmount(2) system calls. So NXT_HAVE_ROOTFS is set to NO on MacOS
and we don't build src/nxt_fs.c
This fixes the immediate build issue by taking the mount/umount OS
support out of nxt_fs.c into a new nxt_fs_mount.c file which is guarded
by the above while we now build nxt_fs.c unconditionally.
This should fix the build on any _supported_ system.

This is a preparatory patch that renames the 'local' and 'local_length'
members of the nxt_unit_request_t structure to 'local_addr' and
'local_addr_length' in preparation for the adding of 'local_port' and
'local_port_length' members.

@alejandro-colomar reported an issue on GitHub whereby Unit would fail
to start due to not being able to create the control socket (a Unix
Domain Socket)
2022/08/05 20:12:22 [alert] 21613#21613 bind(6,
unix:/opt/local/unit/var/run/unit/control.unit.sock.tmp)
failed (2: No such file or directory)
This could happen if the control socket was set to a directory that
doesn't exist. A common place to put the control socket would be under
/run/unit, and while /run will exist, /run/unit may well not (/run
is/should be cleared on each boot).
The pid file would also generally go under /run/unit, though this is
created after the control socket, however it could go someplace else so
we should also ensure its directory exists.
This commit will try to create the pid file and control sockets parent
directory. In some cases the user will need to ensure that the rest of
the path already exists.
This adds a new nxt_fs_mkdir_parent() function that given a full path
to a file (or directory), strips the last component off before passing
the remaining directory path to nxt_fs_mkdir().

This file is used by git (maybe also hg) to map different identities.
It can be used to map different names/email addresses to a preferred
name/email. So if you have authored/committed under different
names/email addresses you can map all these to a particular name/email.
Certain git commands (log, shortlog, show, blame etc) will consult this
file and show the Author/Committer accordingly.
Note: This does _not_ change history, this is simply used by various
commands to alter their output and can be disabled for some commands
with the --no-mailmap option.
This can be useful for commands like git shortlog so that all your
commits are shown under a single identity and also so people have an
up to date email address should they wish to contact you. And just for
overall consistency.
Seeing as I've already committed under two different email addresses
(not counting this one), I've put entries in this file to map my email
addresses to my @nginx.com one.
See also, gitmailmap(5).
