Subject: Rename system test directory with common files to _common
X-Git-Tag: v9.19.18~80^2~4
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=168dba163c266a46a969a87d9020f03a221bf2a5;p=thirdparty%2Fbind9.git

Rename system test directory with common files to _common

The old name "common" clashes with the convention of system test
directory naming. It appears as a system test directory, but it only
contains helper files.

To reduce confusion and to allow automatic detection of issues with
possibly missing test files, rename the helper directory to "_common".
The leading underscore indicates the directory is different and the its
name can no longer be confused with regular system test directories.

 Typically each set of tests sets up 2-5 name servers and then performs one or
 more tests against them.  Within the test subdirectory, each name server has a
 separate subdirectory containing its configuration data.  These subdirectories
