...eate MBR logical partitions. Previously it only supported 4 MBR primary partitions and if you wanted more than that you had to use GPT. The partition filter also supports MBR logical partitions. The python plugin creates plugins which are compatible with Python >= 3.7. Tests are now run under MALLOC_CHECK=1 and MALLOC_PERTURB_=<random>. This causes some tests to crash (silently) because of a shutdown race which needs to be fixed. Test shell scripts now have a generic ‘requires’ function to skip tests if features are not present. C99 type ‘bool’ is now used in most places where appropriate....

Hi I'm getting some instability on my samba 3.0.1 installation. Here's the backtrace I found in my log: Feb 2 19:10:41 grisen smbd[26068]: [2004/02/02 19:10:41, 0] smbd/service.c:make_connection(857) Feb 2 19:10:41 grisen smbd[26068]: audata1 (192.168.1.121) couldn't find service utskrifter Feb 2 19:10:41 grisen smbd[26068]: [2004/02/02 19:10:41, 0]

Reproducing by launching emacs inside of a gnome session. If I use MALLOC_CHECK_=3 /etc/init.d/xdm restart I can sometimes get Xorg w/ nouveau to work for a few days before crashing.

Add an overview libnbd-rust(3) man page pointing to the real documentation. This is like OCaml & Golang. When reviewing the real rustdocs I noticed they basically converted the man pages into plain text, resulting in lots of problems such as internal links not working, no `code` annotations, etc. So I wrote a simple POD to rustdoc translator. It is by no means perfect, but it fixes many of
