Subject: sysdbd: Keep connections open during reconfiguration.
X-Git-Tag: sysdb-0.1.0~103
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=53a8fb0fcbfdd6df1fb688df6a5c3a6cc99f6a3d;p=sysdb.git

sysdbd: Keep connections open during reconfiguration.

By using the new sdb_fe_sock_clear_listeners(), the list of active listeners
may be reconfigured without affecting any open connections.
