Using the Naviserver head on Linux, the installed "conf/nsd-config.tcl"
and "conf/simple-config.tcl" config fieles both work fine for testing
that a newly compliled server starts up correctly. However, simple-config.tcl
includes a commented-out line loading the nscp module, like so:
#ns_param nscp nscp
If you uncomment that line, then the server crashes every time on startup.
If you ALSO copy this "module/nscp/users" section from nsd-config.tcl,
then the crash goes away and server again starts fine:
ns_section ns/server/default/module/nscp/users {
ns_param user "::"
}
Probably nscp shouldn't segfault if it's missing that section? Or
maybe we should either just add that section into simple-config.tcl,
or remove the commented-out nscp line entirely.
When the server crashes because of the missing nscp configuration, the
backtrace looked like this:
