[PATCH] inspection: handle empty file in parse_suse_release
by Olaf Hering
If /etc/SuSE-release is empty then lines[0] is NULL, which is passed to
strdup. As a result virt-inspector will segfault.
This was introduced in commit 763ec36cf0c6ffa6d359b65ff7f1ee9ab1c7361e.

Usage of 'no' as external helper
by Olaf Hering
libguestfs and supermin use 'no' instead of either the basename of the
desired application, or 'false', as helper string. This happens when
configure does not find things like rpm or supermin during build.
Wouldnt it be more logical to use the basename instead of 'no' so that
at runtime one has the chance to install the required packages and in
addition get an obvious error message in verbose mode what external
helper is actually missing? In my package I force a few things like
'export ZYPPER=zypper' to avoid the unneeded BuildRequires: zypper. But
doing that for every binary that maybe called is cumbersome.
I think its best to rely on PATH to let libguestfs and supermin packages
find their external helpers at runtime. And one who has a need to
actually hardcode absolute paths to external helpers into his
libguestfs/supermin binaries can do that by doing the 'export
HELPER=/path/to/helper' during his own configure run.
Thoughts?

hivex: revert much of " Build and test Perl bindings out-of-tree." (887466794a40f57b84ce32524e1a650d6674c7e6)?
by Hilko Bengen
While trying to build the official Debian packages for libguestfs 1.22,
I noticed that instead of working around ExtUtils::MakeMaker's
limitations, I had made quite a mess of building the Perl bindings. I
have tried from different sides to fix things, but could not get it
quite right:
- EU::MM expects Makefile.PL to be in the same directory as the generated
Makefile (We work around that using sed.)
- In principle, there seem to be two ways to do things:
1. Call make -f builddir/Makefile-pl from srcdir (that's what we do
now), override INST_*. Problems with this:
- XS is still built in srcdir.
- there is actually code in ExtUtils::Install which is used from the
generated Makefile-pl that bases its decisions where to install
*.pm files on whether there are any files within ./blib/arch/
(hard-coded)! I have found no way to override this.
2. Call make -f Makefile-pl from builddir. I tried that and thought
that I would be able to patch absolute paths for source files
(*.xs, lib/*) and generated files (*.c, *.xs, blib/*) into the
generated Makefile-pl. Much of a perfectly good weekend went to
waste over that attempt.
I realized that I was actively working against ExtUtils::MakeMaker's
design. Separating source and build trees has never been a concern. Even
if I got it right once, I'd expect things to break in interesting ways
in the future.
>From a look at the documentation, Module::Build does not seem to have a
solution, either.
I give up and propose that we go back to the hackish, yet simple
previous solution and adopt that for libguestfs as well:
-[ $(srcdir) != $(builddir) ] && cp -rsu $(abs_srcdir)/. $(builddir)/.
I agree that this is ugly, but works and it won't hurt when building
libguestfs from within the source directory.
Cheers,

Plan for libguestfs 1.22
by Richard W.M. Jones
It has been 5 months since the last stable release of libguestfs and
over that time we've accumulated many exciting new features:
http://libguestfs.org/guestfs-release-notes.1.html#release-notes-for-libg...
It's time to plan for the release of libguestfs 1.22.
As usual, bugs which have "1.22" (without quotes) in the devel
whiteboard field are nominated as blockers for the release. You can
see a list of those here, currently empty:
https://bugzilla.redhat.com/buglist.cgi?query_format=advanced&field0-0-0=...
or http://tinyurl.com/n7agtte
For a list of all bugs, go to:
https://bugzilla.redhat.com/buglist.cgi?component=libguestfs&product=Virt...
If there are any other features / blockers / problems that need to be
addressed, let me know.
I will also be releasing Ubuntu packages (on libguestfs.org, not in a
PPA) at the same time as the release.
This release will also be the basis for Fedora 19 and RHEL 7.0.
When this release comes out, 1.16 and 1.18 branches will cease to be
supported.
Rich.

[PATCH 1/1] guestfish: Tab-complete single / double quoted filenames containing space -- add fish_completion_word_break_characters_hook
by Jan Lieskovsky
This patch introduces fish_completion_word_break_characters_hook - Readline's
rl_completion_word_break_hook for guestfish so tab-completion on / for single /
double quoted filenames containing space would be possible too - this covers
part:
"In addition:
><fs> ls "/Program Files/<tab>
doesn't show any files to complete."
from RH BZ#547488.
Thank you, Jan.

P.S.: Feel free to remove the comment lines, if you find them unnecessary.
P.S.#2: Have got a patch for completion of unquoted filenames containing space
too already, but need to give it further testing => will submit in
separated post later.
