Subject: [PATCH] hostcheck: fix host name wildcard checking
|
||||
|
||||
The leftmost "label" of the host name can now only match against single
|
||||
'*'. Like the browsers have worked for a long time.
|
||||
|
||||
- extended unit test 1397 for this
|
||||
- move some SOURCE variables from unit/Makefile.am to unit/Makefile.inc
|
||||
|
||||
Reported-by: Hiroki Kurosawa
