This allows to compile ngIRCd using a pre-ANSI K&R C compiler again:
all source files are automatically converted by the included ansi2knr
program (of GNU automake/autoconf) before compiling them with the
K&R C compiler, but a few coding standards must be met.
Tested on Apple A/UX 3.x.
Regression testing on Linux and Mac OS X.
If ngIRCd is compiled to register its services using ZeroConf (e.g. using
Howl, Avahi or on Mac OS X) this parameter can be used to disable service
registration at runtime.
This fixes the following gcc compiler warning:
tool.c: In function 'ngt_SyslogFacilityName':
tool.c:195: warning: return discards qualifiers from pointer target type
The new option "SyslogFacility" deines the syslog "facility" to which
ngIRCd should send log messages.
Possible values are system dependant, but most probably "auth", "daemon",
"user" and "local1" through "local7" are possible values; see syslog(3).
Default is "local5" for historical reasons.
These both functions translate syslog facility names to ID numbers
and vice versa. On systems that don't define the facilitynames[] array
in syslog.h, we try to build one ourself.
This fixes the following gcc warning, emitted by Xcode:
src/ngircd/sighandlers.c: In function 'Signal_Callback':
src/ngircd/sighandlers.c:239: warning: implicit conversion shortens 64-bit value into a 32-bit value
Signals_Init() must only be called once.
This does not affect any ngircd release version.
Earlier version of this patch moved the io and sighandler
initialization before the while() loop, but as Alexander
Barton noticed that broke all systems without builtin select
support in io.c...
- declare signals_catch[] array not between the function implementations.
- rename now local function NGIRCd_Rehash() to Rehash().
- remove empty and therefore not used "catch SIGHUP; break;".
This patch allows ngIRCd to dump its internal state (connected clients,
actual configuration) when compiled with --enable-debug. The daemon
catches two more signals:
- SIGUSR1: toggle debug mode (on/off),
- SIGUSR2: dump internal state to console/syslog.
now that the main signal handling is done from the dispatcher
loop we can call NGIRCD_Rehash() directly.
the /REHASH handler can queue the Rehash() function for
execution by sending a SIGHUP. It will be run when we
return back to the dispatch loop.
Allows to defer/queue signal processing for execution on the next
event dispatch call, i.e. we can perform any signal action in
normal, non-signal context.
Example uses:
- Reload everything on HUP without writing a global "SIGHUP_received"
variable
- Dump status of internal Lists on SIGUSR1, etc.
Fix synchronization of established connections and configured server
structures after a configuration update:
- Not only test servers that already have a connection, but also check
and update configured servers to which a new connection is beeing
established (SERVER_WAIT state).
- And do the server name comparision case-insensitive.
Let CheckServers() not only skip servers that already have a
connection, but also skip servers to which a new connection is
already beeing established (SERVER_WAIT state).
This fixes PING-PONG lag calculation (which resulted in "0" before).
The "lastping" time is still reset it if a time shift backwards has
been detected to prevent the daemon from miscalculating ping timeouts.
When a client has user mode "x" set, its real hostname is cloaked
by substituting it with the server name (as configured in ngircd.conf).
Restricted clients (user mode "r") aren't allowed to change mode "x".
Please note that hostname cloaking is only in effect in server-client
communication! The server still uses the real hostname for its own
logging and for all server-server communication -- therefore all servers
in the network must support user mode "x" to prevent older servers
from leaking the real hostname of a cloaked client!
