Fix multiple formatting problems in HTML docs The rule generating the HTML docs passing the --html flag to xsltproc. This makes it use the legacy HTML parser, which either ignores or tries to fix all sorts of broken XML tags. There's no reason why we should be writing broken XML in the first place, so removing --html and adding the XHTML doctype to all files forces us to create good XML. This adds the XHTML doc type and fixes many, many XML tag problems it exposes. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

docs: switch to using HTML5 doctype declaration The HTML5 doctype is simply <!DOCTYPE html> no DTD is present because HTML5 is no longer defined as an extension of SGML. XSL has no way to natively output a doctype without a public or system identifier, so we have to use an <xsl:text> hack instead.

Explicitly force separate build dir in autotools to align with meson. We must re-enable dependency tracking which the RPM %configure macro turns off.

build: honor autogen.sh --no-git Based on a report by Chandrashekar Shastri, at https://bugzilla.redhat.com/show_bug.cgi?id=979360 On systems where git cannot access the outside world, a developer can instead arrange to get a copy of gnulib at the right commit via side channels (such as NFS share drives), set GNULIB_SRCDIR, then use ./autogen.sh --no-git. In this setup, we will now avoid direct use of git. Of course, this means no automatic gnulib updates when libvirt.git updates its submodule, but it is expected that any developer in such a situation is already prepared to deal with the fallout. * .gnulib: Update to latest, for bootstrap. * bootstrap: Synchronize from gnulib. * autogen.sh (no_git): Avoid git when requested. * cfg.mk (_update_required): Skip automatic rerun of bootstrap if we can't use git. * docs/compiling.html.in: Document this setup. * docs/hacking.html.in: Mention this. * HACKING: Regenerate.

Forget last daemon/ dir artefacts The most important part is LIBVIRTD_PATH env var fix. It is used in virFileFindResourceFull() from tests. The libvirtd no longer lives under daemon/. Then, libvirtd-fail test was still failing (as expected) but not because of missing config file but because it was trying to execute (nonexistent) top_builddir/daemon/libvirtd which fulfilled expected outcome and thus test did not fail. Thirdly, lcov was told to generate coverage for daemon/ dir too. Fourthly, our compiling documentation was still suggesting to run daemonn/libvirtd. And finally, some comments in a systemtap file and a probes file were still referring to daemon/libvirtd.

It is also possible to run virsh directly from the source tree
Add a ./run script for running programs from the local directory. With this script you can run libvirt programs without needing to install them first. You just have to do for example: ./run ./tools/virsh [args ...] If you are already in the tools/ subdirectory, then the following command will also work: ../run ./virsh [...] You can also run the C programs under valgrind like this: ./run valgrind [valgrind opts...] ./program or under gdb: ./run gdb --args ./program This also works with sudo (eg. if you need root access for libvirt): sudo ./run ./tools/virsh list --all Derived from libguestfs and simplified. The ./run script in libguestfs is much more sophisticated: https://github.com/libguestfs/libguestfs/blob/master/run.in
