Обсуждение: Vista/IPv6
On Windows Vista, IPv6 is enabled by default, and cannot be uninstalled, or disabled easily on the loopback adaptor. localhost is ::1 by default, and the enhanced 'security' makes it insanely difficult to edit the hosts file. This means that the regression tests fail to run, leaving a postmaster.log full of 'no pg_hba.conf entry for host ::1' errors. Should we have initdb enable the ::1 pg_hba.conf trust entry by default on Vista? Any better options? Regards Dave

Let me pre-emt the discussion by saying that the msvc build does not detect ipv6 on the build machine (yet). Are you building with msvc or mingw on this machine? //Magnus

Something is broken then, because it clearly is turned on, yet the pg_hba.conf entry is commented out - hence my report. I assume it's initdb that's doing the check? Regards, Dave.

None, so far :-) Point being - if you build on a ipv6 enabled machine, will that binary then work at all on a non-ipv6 machine? Consider binaries distributed by the installer... Might as well think up the proper fix before we just band-aid it for the regression tests.. //Magnus

The check is done by initdb (not on the build machine) and it checks if
getaddrinfo("::1", ...) works. If that doesn't work then you don't have IPv6
for all practical purposes. So everything seems to be set up all right.

There is a configure time and a runtime check. The code is below - note
the first #ifdef.

That was my question. I just built with ipv6 enabled using my msvc build on my primary machine which does *not* have ipv6, and it still passes regression tests fine. Given that we have a runtime check, is there any reason at all not to enable ipv6 on all builds on msvc? (FWIW, it's been in the platform SDK at least since Windows 2000) //Magnus

I wonder how many other little bits we miss out on? Anyway, the obvious fix seems to be to add a line to src/tools/msvc/Solution.pm to #define HAVE_IPV6 1 in pg_config.h cheers andrew

I > wonder how many other little bits we miss out on? Well, if you can make that happen, certainly that'd be nice... (FWIW, I had ipv6 on my list of things to make happen, but I didn't realise it would cause this issue on a machine with ipv6 on it, since I don't have one) > Anyway, the obvious fix seems to be to add a line to > src/tools/msvc/Solution.pm to #define HAVE_IPV6 1 in pg_config.h Won't work, that hits both msvc and mingw. (assuming you maen pg_config.h.win32, since pg_config.h is a generated file) The proper fix is to put it in the msvc build sys, where it writes pg_config.h :-) It also needs a new lib for initdb. I have a patch for it, and it works here, I'm just asking if it's safe to enable it or if it may cause runtmie problems on platforms without ipv6. //Magnus

That seems odd since what we do on MinGW does work. The winsock libs. Our mingw build links them explicitly to all binaries, the msvc build only links it to the ones that actually need it. And with ipv6 support, initdb suddenly needs it. //Magnus

Try it and find out ;-) ... that's what we have a buildfarm for.

I suggest that you just use the logic that we have or emulate it, respectively. If it doesn't work, we will find out soon enough. -- Peter Eisentraut http://developer.postgresql.org/~petere/

The point is still what happens when you distribute a binary built on a system with ipv6 to a system that doesn't have it. Anyway. It seems reasonably safe, since I can build with ipv6 on my machine without the ipv6 driver, and it still works. Dave will have to test if it actually works on a machine that *has* ipv6 :-) So.

The only option if we were to go with that is, IMHO, to move *everything* over to it. And I don't think you'll get a lot of people supporting that ;) //Magnus

I don't have IPV6 test environment recently.... However, It has the compile environment of VC6, and it is finished finely. Then, win32.mak is not the thing of only VC6. And VC 7.1, VC8, and they will be used. It should be then supported IPV6 at least. What confirmed #DEFINE of IPV6 and built it by VC6 has passed the test of IPV4 further again. Therefore, you should make it effective. Regards, Hiroshi Saito
