debian/ubuntu package files

[vnaum]

Please check list of files to install: I have no idea what has to be installed, and there was no 'install' rule in Makefile, so I added single file install into /usr/bin/snabbsandwich

If there are more files (config file, man page, scripts, crontab entries), or if /usr/sbin fits better for snabbsandwich (like, if this root-only program) - let me know.

I added some description/URLS in control file, rest of package is fresh out of dh_make — lots of example stuff and such.

@vladfedin, take a look pls.

May be it's also possible / desirable to somehow install auto-testing script?
@altexy can you help us here on any other files needed?

[altexy]

At the moment selftests code are mixed with library code.
So it is installed with snabbswitch executable.
But some test require also test data.
At the moment it is not simple to distinguish them.

I have create a new issue about - #124

[agladysh]

OK, thanks. @altexy, can you please verify if the package installs everything what we need?

[altexy]

The simplest way is to run any test which does not require test data, rate_limiter for example:
sudo snabbswitch -t apps.rate_limiter.rate_limiter

End of rate_limiter selftest FYI:

 if not ok then
      print("selftest failed")
      os.exit(1)
   end
   print("selftest passed")

@vnaum, is it enough info to proceed?

Link to binary packages (snabb/nova/qemu/libvirt/neutron) I've built:
http://vnaum.com/misc/201403/
(had to skip autotests with DEB_BUILD_OPTIONS=nocheck)

I've built from my source repos:
https://bitbucket.org/vnaum/nova/commits/branch/xmas-demo
https://bitbucket.org/vnaum/sns-neutron/commits/branch/sns-agent1
https://bitbucket.org/vnaum/libvirt-1.2.1/commits/branch/master

Do end users have any need for this test data?

If it's just for development purposes - let it stay in source repo, no need to clutter binary package.

If it can be handy for users as an example of how snabbswitch can work or as a template for custom scripts/scenarios,
/usr/share/doc/snabbswich/examples is a good place for it (with comments).

If test data is essential for snabbswitch (snabb is useless without it, and everybody will need it) - /usr/lib/snabbswich is a correct place.

So it is installed with snabbswitch executable.

Wait, there is some installation script / routine?
Last time I checked 'install' was not even a target in Makefile, so I had to add it.
Anyway, for package building purposes it's quite easy to tell what goes into a package: only stuff that "make install" installs does.

I think we should have as few files as we possibly can in the package for snabbswitch. The snabbswitch binary, a manpage, maybe an example config... can we get away with so little?

[lukego]

(OK, maybe we'll want an init.d script, but we don't have that yet...)

[vnaum]

can we get away with so little?

From my point of view we totally can.
Is manpage sitting somewhere in source tree, or it has to be written yet?
There are 3 manpage templates in /debian dh_make provides, .1, docbook .sgml and docbook .xml - feel free to use one and remove .ex suffix.
There also is an init.d skeleton file there. Same stuff, add your options and remove .ex suffix.

[lukego]

That sounds good :)

snabbswitch package can probably have a short (even empty?) dependency list.

Perhaps we will want to make a snabbswitch-nfv meta-package that installs the base snabbswitch + all of the virtualisation stuff, but I think we can take that later.

[vnaum]

Well, It's never empty — you depend on libc at least, and probably need some minimum kernel version, but the idea behind this was "user installs snabbswitch and gets every requirement pulled". As you suggest, meta-package can be done that depends in both snabb and "everything".

This one is now obsolete, see #131

JFYI Here is a mailing list thread with somebody else trying to build a patched version of Neutron for an Ubuntu PPA: http://www.mail-archive.com/openstack-dev@lists.openstack.org/msg20902.html
