[PATCH for-xen-4.5 0/3] tools: build system fixes and cleanups

[Daniel Kiper]

Hi,

Here are three tools build system patches:
  - tools/hotplug: distclean target should remove files generated by configure,
  - gitignore: ignore some files generated by configure,
  - gitignore: group tools/hotplug files in one place.

First two are real fixes. Last one is a cleanup which is nice to have
but not required at this stage of 4.5 development.

This usage scenario which I can see this being useful (and
I've tripped over this) is when you rebuild a new version
from the same repo. As in, this affects developers, but
not end-users and not distros. But perhaps I am missing
one scenario?

As such I would lean towards deferring this (and the other
two) to Xen 4.6.

Thank you!

As I know Debian build system sometimes complain if make distclean
does not leave build tree in distclean state (read "state before
configure" != "state after distclean"). It means that from
distros point of view we should apply this patch. However,
other two are not required and we can deffer them to Xen 4.6.

Debian is shipping 4.4 in the next release (8, Jessie, already frozen)
and I think it likely that the release after that will ship something
greater than 4.5 due to the timelines involved.

In any case, the Debian Xen packages cannot have any bugs of the kind
mentioned here because the package copyies the source to
debian/build/foo (for reasons other than distclean) and nuking the
entire of debian/build on clean.

.gitignore updates seem harmless enough. so I've applied this and the
third patch. Awaiting Konrad's verdict on the first.

Lets get it in. It fixes an issues that I keep on tripping
on and it is harmless enough that I don't see a way
for this to cause any regressions.

Configure generates a boatload more things than this, see e.g. 

$ grep hotplug/ tools/configure.ac 

Perhaps the answer would be to recurse into tools/hotplug/* and refactor
the existing XEN_SCRIPTS to have the generated stuff in XEN_SCRIPTS_GEN
instead and XEN_SCRIPTS += $(XEN_SCRIPTS). The on distclean remove the
XEN_SCRIPTS_GEN ones.

It's not ideal, but at least it puts the distclean logic in the same
place as the logic to install the files, if not their generation, which
at least increases the chance of someone adding it to the right place.

Ian.

Daniel pointed to me that the two other patches that were committed
solve the problem of seeing those auto-generated files sticking (and
forcing one to use git checkout XYZ -f).

So this small patch can be ditched in favour of the more encompassing
design that you have sketched out.
