Very small patch against actsync

[Holger Wirtz]

Hi,

I had problems with actsync and microsoft newsservers. Some of them carry group
names case-insensitive and some do not. So nearly every actsync means that
some groups are flapping because the names are different for actsync.

The son_of_RFC1036 says that groupnames should be used case-insensitive:

        [son_of_1036]
        NOTE: Possibly newsgroup names  should  have  been
        case-insensitive, but all existing software treats
        them as case-sensitive.   (RFC  977  [rrr]  claims
        that they are case-insensitive in NNTP, but exist-
        ing implementations are believed to ignore  this.)
        The simplest solution is just to ban use of upper-
        case letters, since no widespread  newsgroup  name
        uses  them  anyway; this avoids any possibility of
        confusion.

I made a simple patch against actsync.c (INN-2.2.2):

--- cut here ---

*** actsync.c.orig      Wed Jan 26 13:07:47 2000
--- actsync.c   Wed Jan 26 14:51:34 2000
***************
*** 1222,1227 ****

        }
        strncpy(cur->name, line, QIOlength(qp));
        cur->name[QIOlength(qp)] = '\0';
+       string_tolower(cur->name);      /* wirtz at dfn.de */

        /* get the group name */
        if ((p = strchr(cur->name, ' ')) == NULL) {
***************
*** 3574,3576 ****
--- 3575,3583 ----
       */
      return result;
  }
+
+ void string_tolower( char *sz )
+ {
+   while( *sz = tolower( *sz ) ) sz++ ;
+ }
+

--- cut here ---

I hope you can use this in later versions of INN.

Regards, Holger
