Subject: fetching an svn repository always results in a different hash
Date: Mon, 23 Apr 2018 17:44:08 +0200

Hi,

I'm trying to use svn-fetch in a new package, but I always get a 
different hash when I try to download the sources. I think this is due 
to fetching external resources. Here are two adresses that trigger this 
bug:

- http://svn.netlabs.org/repos/kbuild/trunk
- https://svn.openstreetmap.org/applications/editors/josm

Here is a package definition I try to use:

(define-public kbuild
  (package
    (name "kbuild")
    (version "0.1.9998")
    (source (origin
              (method svn-fetch)
              (uri (svn-reference
                     (url "http://svn.netlabs.org/repos/kbuild/trunk")
                     (revision 3025)))
              (file-name (string-append name "-" version))
              (sha256
               (base32
                
"1k7y2lqqhsfwfzzi7rms7a2kakimm7g46qa2gypkvzdd3drbpanj"))))
    (build-system gnu-build-system)
    (home-page "http://trac.netlabs.org/kbuild/wiki")
    (synopsis "Makefile framework")
    (description "kBuild is a makefile framework for writing simple 
makefiles
for complex tasks.")
    (license license:gpl3+)))

Can you try comparing the differences between the downloaded archives?
The diffoscope program will be useful.

There are differences in .svn/wc.db. The top .svn directory is removed,
but there are other .svn directories that are not removed and contain a
wc.db file. In my case, src/lib/kStuff/.svn is kept intact and differs
every time.

I think we should change guix/build/svn.scm to also delete the other ".svn"
directories.

Those contain state that is not necessary for the build - and since it's
causing trouble, we can just remove them.

This is now fixed on master. Closing.
