- Disable USE_POLL on Windows, since it doesn't work with XP and has
no advantage anyway. Reported by nenolod (#4129).
- Various updates to makefile.win32 and .iss file, found during
building new versions of zlib, openssl, and curl.
server.cert.pem exists, and check it if the file doesn't exist.
You can still change the setting, just the default is correct now.
The code for this was already there but was not working correctly
causing users to go through the generation process upon each install.
If this is not set, then SASL is off and not advertised.
If the specified server is not connected, then SASL is off as well.
This prevents unnecessary delay (and the inability for some clients to
get online) when SASL is not in use or when the SASL server is down.
This allows the IRCd to enforce MLOCKs that are set by services, which
eliminates clashes between users setting modes and services enforcing
it's mlock on channels. (#3055)
queued data on the receive queue (eg: due to fake lag) was not processed
unless we got new data from the client.
Now, better document this. Also, avoid calling dbuf_put with 0 length.
goes to the boot screen. When we are already booted it's sent to all
IRCOps with a limit of max. 1 message per 5 minutes.
- Refuse to boot when we can't write to any log file.
vmakebuf_local_withprefix. Then use this new function - which creates the
buffer-to-be-sent - at the top of functions like sendto_channel_butserv
and sendto_common_channels and send the prepared buffer in the loop that
comes after it. This means we only prepare the buffer once and then send
it many times, rather than both building and sending it XYZ times.
Benchmarking connect-join-quit of 10k clients:
100 users per channel: no noticeable speed improvement
1000 users per channel: 18% faster
10000 users in one channel: 50% faster
As you can see, unfortunately, for a typical irc network there isn't much
speed improvement. However, if you have a couple of 500+ user channels or
get attacked by clones then you may see some improvement in speed and/or lower
CPU usage.
- UnrealIRCd now supports poll() instead of select().
There are some minor speed benefits if you have more than 1K or 2K
clients, however the main noticeable difference is that on Linux you can
now easily enter a higher maximum connection count than 1024 in ./Config,
without having to edit system header files.
Of course, you still need to be allowed to use the # of sockets (type
'ulimit -n' on the shell).
Support for this is experimental at this stage, but enabled by default
so it can receive all the testing it deserves. If all goes well, it will
be the default for 3.2.10.
Stress testing is very much welcomed!
on OpenFiles to be correct. This fixes a crash when f.e. 3rd party modules
have files open but don't increase OpenFiles. Might also fix a curl crash,
though nobody ever reported one.
and ensures that the user does not have any ircop-only user modes after
de-opering. This (only) fixes the just added +I umode case, but could
also prevent future bugs.
