Subject: [devel] [PATCH] Verbose QueryTags prints whether tag is an extension
Date: Sat, 11 Apr 2020 02:19:17 +0300
Message-ID: <20200410231917.1482336-1-vseleznv@altlinux.org> (raw)

Verbose QueryTags prints four field: tagname, tagvalue, tagtype and whether
it is an extension. To make it possible QueryTags uses new function
rpmTagIsExtension() that return 0 if tag is real, 1 if tag is an extension
or 2 if tag is not found.

* lib/query.c(rpmDisplayQueryTags): Print whether tag is an extension.
* lib/rpmtag.h(rpmTagIsExtension): New definition.
* lib/tagname.c(rpmTagIsExtension): New function.
