The debug log messages are always available and a runtime option (since
commit c7de505c), but the assert()'s are only active when ngIRCd was
configured with the "--enable-debug" option.
So only add "+DEBUG" to the version string when the latter is the case.
This basically means to unifdef DEBUG in (almost) all places.
We keep it in src/portab/portab.h so DEBUG stays available to
enable assert(). Also add a comment about this.
Implement new numeric ERR_INVALIDMODEPARAM_MSG(696) and:
- Reject channel keys with spaces and return ERR_INVALIDMODEPARAM_MSG;
This was possible until now and resulted in garbled IRC commands later.
- Reject empty channel keys and return ERR_INVALIDMODEPARAM_MSG;
This was possible until now and resulted in garbled IRC commands later.
- Return ERR_INVALIDMODEPARAM_MSG when user limit is out of bounds;
This was silently ignored until now.
Closes#290. Thanks Val Lorentz for reporting it!
This relates to #290 and considerations which errors to show when: and I
think it is the better approach to give feedback instead of silently
failing.
Note that this code path is also used when handling modes of channels
defined in "[Channel]" blocks in configuration files: in this case the
client is the local server and we can't send messages to it, because it
has no socket connection! Therefore we need those "is_machine" checks
and log an error im this case.
Don't forbid the local server to change modes on local channels: this
happens when overriding modes on local (&) channels in the server
configuration file, for example, and is perfectly fine.
Without this patch, the server worked as expected but showed critical
error messages for each local channel in its configuration file:
"Got remote MODE command for local channel!? Ignored."
Conf_GetServer() can return NULL when the server introducing the client
had a write error for example, and is being disconnected.
So make sure that we have a valid server before calling Conf_NickIsService()!
This fixes the following compiler warning, for example on OpenBSD:
conf.c: In function 'Conf_Test':
conf.c:391: warning: format '%ld' expects type 'long int', but argument
2 has type 'time_t'
Thanks to Götz Hoffart for reporting this!
Basically, the issue described in #281 is that the test suite uses the
IPv4 address 127.0.0.1 on an IPv6-only host. But this is the "safest"
thing to do in (almost) all other setups: relaying on DNS host names
makes things even more complex, as different systems map 127.0.0.1
differently (including the reverse lookup; that's why we switched to
127.0.0.1 back in 2014, see commit 3f807e1045).
But with AI_ADDRCONFIG set, on an IPv6-only host, we prevent 127.0.0.1
to get translated properly, even when the loopback interface has this
address configured! So don't set it any more.
The drawback is that the resolver possibly returns more addresses now,
even of an unsupported/not connected address family; but this shouldn't
do much harm in practice, as ngIRCd iterates over all returned addresses
while trying to establish an outgoing connection.
Closes#281.
The ISUPPORT(005) numeric lists only channel prefixes which are listed
in the "AllowedChannelTypes" configuration option. And if this is the
empty string ("") for example, this now results in IRC clients assuming
"oh, no channel prefix characters at all, so no channels at all, so no
PRIVMSG can go to any channel" -- which is not the case when there are
pre-defined channel set up or other servers still having channels!
So "allowed channel types" != "supported channel types", and we always
have to list all supported ones in the ISUPPORT(005) numeric!
This reverts commit 4b7e8db418.
Closes#285.
On reload, all listening ports are closed, configuration updated, and
then opened again. Which leads to subsequent tests running while the
daemon isn't listening on any ports, and that's why the tests fail.
The "proper" way whould be to loop and check for open ports, but waiting
is what the start-server.sh script does right now, so stick with this in
reload-server.sh for now as well.
This fixes the issue, at least on my RaspberryPi ...
Closes#280.
It can happen that a channel is +k, but no key is set: for example by
misconfiguring a pre-defined channel. In this case, ngIRCd sent an
invalud CHANINFO command ("CHANINFO #test +Pk 0 :'", note the unset
key represented by the two spaces) to its peers.
Fix this and enhance the CHANINFO documentation.
