Hello.
In
https://www.exim.org/exim-html-current/doc/html/spec_html/ch-file_and_database_lookups.html#SECID60
for "dsearch" lookup type there is a statement:
| The "filter" option requests that only directory entries of a given type
| are matched. The match value is one of "file", "dir" or "subdir" (the
| latter not matching "." or "..").
But experiment (with "Exim version 4.94 #2 built 19-Jun-2020 08:31:26"
for Debian) shows that "." is matched in for both "dir" or "subdir":
# /usr/sbin/exim4 -be '${lookup {.} dsearch,ret=full,filter=dir {/var}{x=$value}}'
x=/var/.
# /usr/sbin/exim4 -be '${lookup {.} dsearch,ret=full,filter=subdir {/var}{x=$value}}'
x=/var/.
Not match documentation.
And I'm just curious, what a usage pattern was targeted to create two
distinct filters "dir" and "subdir" with such small difference?
