The ext2 filesystem on disk format has two ways to store symlinks. For symlinks >= 60 bytes in length, they are stored as files (so-called "slow symlinks"). For shorter symlinks the symlink is stored in the inode ("fast symlinks"). Previously we only created slow symlinks even if they are shorter than 60 bytes. This didn't matter until recently, when a change went

http://dovecot.org/test/ This release is built with autoconf 2.59 and libtool 1.9. We'll see how it works out :) The required changes were done by Matthias Andree. - The last fix for connection hanging made IDLE use 100% CPU - We don't use Maildir/.INBOX/ directory anymore, indexes are stored in Maildir-root - Don't crash with FETCH BODY[n.MIME] - Changed %p (protocol)

Currently the build systems sets ARCH based on the result of 'uname -m'. On a mixed 32/64 system (one with a 64-bit kernel and a 32-bit userspace) this will result in "x86_64" which is wrong. We'd like the ARCH variable to represent the userspace we're compiling in/for, not what the kernel happens to be. Does anyone know of a clean way to detect this sort of system

Cleanest way is probably to explicitly test if __x86_64__ is defined, ie AC_COMPILE_IFELSE([AC_LANG_PROGRAM( [[#ifndef __x86_64__ error: Not x86-64 even if uname says so! #endif ]])], [ARCH=x86_64], [ARCH=i386]) Or in the alternative you can always key off sizeof(void *) == 8.

...us.name QA Contact: rsync-qa at samba.org There are a few autoconf macros in use deemed obsolete upstream with straight forward alternatives. The autoscan tool can correct most of them, but there are two that take a little bit of code analysis. Most items are replacing AC_TRY_COMPILE with AC_COMPILE_IFELSE. Of those taking a bit more code analysis, there is the assessment by the autoconf developers that sufficient time has passed that you can assume the signal return type. In other words, it's my understanding that instead of having it return RETSIGTYPE and having autoconf determine the type, it...
