I prefer dh over cdbs over long debhelper form. Are there any
technical reasons for not using dh?
Good question. Thanks for asking!
...and your question was easy and quick to answer exactly because you
only asked for a one-sided view, not a(n attempt at) full comparison,
which I suspect this thread may now turn into...
CDBS is more backports-friendly (beyond backports.org too!).
That's true. Using bleeding edge packaging tools make backporting
harder.
CDBS provides routines to fetch and repackage upstream tarballs
I don't use this feature, but it could be useful.
CDBS provides routines to track copyright and licensing info of sources.
That's nice. Where do I can read more about it?
Hehe, that's actually one thing CDBS lacks: proper and up-to-date
documentation!
...and I don't even blog about it (yet - that's one of the planned
outcomes of the Ikiwiki work I do with my girlfriend: she slowly started
blogging quite some time ago but I set a bar so high for myself
regarding needed features that I still - after a couple of years
working on it - don't feel ready).
Here's a quick intro (from my head - hope it works):
1) Include /usr/share/cdbs/1/rules/utils.mk
2) touch debian/copyright_hints
(else you will simply be suggested to do this at each build)
3) build as usual
4) copy the autogenerated debian/copyright_newhints to debian/copyright
and verify and clean it up manually
...or what I do, and find smarter, is at 3) to a) build with maintainer
mode enabled[1], b) manually apply patches, and c) only build the
minimal necessary for the licensing check. Like this:
QUILT_PATCHES=debian/patches quilt push -a
DEB_MAINTAINER_MODE=1 debian/rules pre-build
Also, I cleanup with maintainer mode enabled, which keeps the
debian/copyright_newhints file but tidy other noise in source:
DEB_MAINTAINER_MODE=1 fakeroot debian/rules clean
QUILT_PATCHES=debian/patches quilt pop -a
CDBS is less invasive - e.g. can be used with manually run dh_*
commands
You can use override_dh_* to run a dh_* command manually.
I might be wrong, but it seems to me that with short-form dh you add
debhelper to *every* build target, trusting it to then properly handle
anything thrown at it.
Yes, you can then explicitly disable parts of it - for the parts that
debhelper happens to support disabling.
What you do with CDBS is *not* enabling the parts you don't want CDBS to
handle for you. As the prime example, you can choose to not let CDBS
handle your debhelper routines but add that by hand. When I discourage
using CDBS together with short-form dh it is because I fear debhelper
being too intrusive and automagically taking over parts that it
shouldn't. I would be more than happy to be assured that this is not
the case, and they indeed work nicely together as long as you simply do
not include the CDBS debhelper.mk snippet.
CDBS is written in make (short-form dh somewhat reinvents make in
Perl)
Yes, but Makefile rules can get complicated. Do you want an example? I
like dh because it's simple.
Perl code can be complex too. You just tend to not look at that code.
What obviously helps is documentation. I never used documentation
myself for CDBS, just looked at the snippets, and I agree they may look
scary to someone not intimate in make (similar to autotools being
disliked by many).
Kind regards,
- Jonas
[1] DEB_MAINTAINER_MODE enables features ireelevant or even policy
violating to do by default (e.g. on build daemons). It makes the
copyright-check routien fail, not just warn, in case of new or changed
copyright and licensing info - which is always the case when you've
initially touch'ed the file.
