- Log ----------------------------------------------------------------- commit d0b6df67b7245bb84dcdb9c0050ed6897aae1bcd Author: Ricardo Signes <[email protected]> Date: Mon May 14 12:26:36 2012 -0400 next release will be RC1 M patchlevel.h commit 725df607777c0fcde7dd1ffd8e251d60926ffef6 Author: Ricardo Signes <[email protected]> Date: Mon May 14 12:26:24 2012 -0400 perldelta: fix version named in acknowledgements M pod/perldelta.pod commit 39fa9b09c5302747dfc83c8cffd2ae9e2df5f921 Author: Nicholas Clark <[email protected]> Date: Mon May 14 10:17:06 2012 +0100 In the Linux hints, invoke gcc with LANG and LC_ALL set to "C". The output of gcc -print-search-dirs is subject to localisation, which means that the literal text "libraries" will not be present if the user has a non-English locale, and we won't determine the correct path for libraries such as -lm, breaking the build. Problem diagnosed by Alexander Hartmaier. M hints/linux.sh commit 9c80a07187cd4c4241fd700957893a40d7ef4861 Author: Paul Johnson <[email protected]> Date: Mon May 14 09:45:10 2012 +0100 Don't test that errno is still 0 after POSIX::f?pathconf I think the best we can do with respect to the f?pathconf tests is to make sure that the perl call doesn't die, and that the system call doesn't fail. And it's arguable we should only be testing the former. But since we've been testing more that this anyway, it's probably safe to test both. With respect to the sysconf call, I think we shouldn't test more than that perl doesn't die. Any further testing would require different tests based the argument being passed in. Before doing that, it's probably worth considering the purpose of the tests. I don't think we really want to test that POSIX has been implemented correctly, only that our layer over it is correctly implemented. This fixes RT #112866.
