First of all, system-wide curl is much preffered, but if not available
then UnrealIRCd will offer to install curl for you during ./Config.
The prompt looks the same as before but we no longer install the curl
library in ~/curl but rather in ~/unrealircd/lib (or wherever you put
your installation).
Basically, it now behaves exactly the same as c-ares, TRE and PCRE.
Downside: curl will be re-compiled each time you re-run ./Config
Upside: curl will be re-compiled each time... :D.. will thus be kept
more up to date.
**
Also: complain if <curlinstall>/bin/curl-config cannot be found.
This ensures we error after ./Config rather than after the whole of
configure has been ran.
don't support this and will fail to compile UnrealIRCd. This fixes#3680,
reported by therock247uk.
- Upgraded c-ares to 1.6.0 (also now using pkg-config).
If you get a "undefined reference to `clock_gettime'" error, then you
might consider installing 'pkg-config' on your system, and then simply
re-run
./Config and make, should fix things.
__TODO__: win32 c-ares upgrade to 1.6.0 (and copy & fix header files).
__TODO__: testing! testing! i'd like to be sure this c-ares is stable!
including one reported by frigola on an old Sun Cobalt RAQ3.
It will probably also fix an issue with the just released curl 7.15.4, if compiling
with remote includes.
TODO: Update win32 (not urgent)
- '/quote dns i' now shows the nameserver settings (which is taken from /etc/resolv.conf
on *NIX, and from the registry on Windows)
- We no longer depend on a C++ compiler (was useless c-ares dependency caused by libtool)
- '/REHASH -dns' now rereads the resolver data from resolv.conf/registry, no IRCd restart
needed anymore. It's currently kinda experimental however, but I *think* it will work ok.
Unfortunately the above features required some ugly hacks if curl was enabled, so if you
use curl (Remote includes), feel free to test on your OS (Linux, but especially FreeBSD
and the other *NIXes) to see if things still compile (make clean; ./Config && make).
This should get rid of some annoying untracable (and usually rare) crashbugs in the
old resolver. Besides that, it makes things look more clean and understandable.
This should be the fix for the following bugids (all the same issue): #2499, #2551, #2558,
#2559, #2603, #2642, #2502, #2501, #2618, #2616.
Feedback and testing is very much welcomed (syzop@unrealircd.com).
