BTW, if I set error_log to "warn", I do see:
2020/12/01 00:32:46 [warn] 7356#7356: *1 using uninitialized "test_var"
variable while logging request, client: 127.0.0.1, server: _, request: "GET
/ HTTP/1.1", host: "localhost"
The confusion was whether those uninitialized variables should be logged
Thanks Maxim,
If I understand correctly, the uninitialized custom variable is the same as
a variable initialized as "". That's why we don't see "-", but only see "".
Only internal variables will have the special "-" treatment.

ok, for testing, I removed the variable from the map, and add one line in a
2-way SSL server config, to create a fresh new variable:
set $test_var "test";
For a request without client cert (400), I see neither "test", nor "-" in
the access log for $test_var. I only see blank, as if the $test_var

When a variable value is not found, it'
I may have mixed this with special upstream variables, eg:
$upstream_http_something. When upstream response header doesn't existing,
the variable was logged - in the nginx access logs.

Hi,
If I create a variable, default to blank:
map upstream_env $upstream_env {
default "";
}
and log it in access log (log_format has $upstream_env). I see a "-" in the
log file, which is as expected, but for a 2-way SSL virtual host, I don't
see the "-", just blank. Is that a bug?
