This is required for backwards compatibility when installing the -full
or -full-dbg package variant: PAM is enabled now but no configuration
present, so all login attempts would be denied ...
Creating /etc/pam.d/ngircd including "auth required pam_permit.so"
restores the old behaviour of allowing all connections.
disable pam_fail_delay() only is available starting with Mac
OS X 10.6; but we use the 10.5 SDK for campatibility, so don't use
this function at all when building using Xcode.
Now the ngIRCd release/version number is deduced from the "current"
annotated GIT tag; see "git describe --help" for details. This is the
same scheme the Linux kernel uses and gives much more details version
numbers for interim releases and inofficial source archives generated
using "make dist".
Please note: the version number is only updated it the autogen.sh
script is run; so after pulling in and pushing out new commits, you
should run ./autogen.sh!
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).
