Please describe the problem.

I noticed three tests failed when running "git annex test", and it seems it's because I have annex.backends set to SHA256 in ~/.gitconfig. When I disable that option, all tests succeed.

What steps will reproduce the problem?

Add

[annex]
  backends = SHA256

to ~/.gitconfig.

What version of git-annex are you using? On what operating system?

Newest git-annex (6.20160211 amd64) from downloads.kitenet.net.

  • Debian GNU/Linux 8.3 (64 bit). Installed yesterday, so it's pretty pristine.
  • git version 2.7.1.287.g4943984 (Newest version from 'master' in git.git)

The first version with this problem is 6.20160114. 5.20151218 works.

Please provide any additional information below.

3 out of 269 tests failed (640.58s)

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Roses are red
Violets are blue
git-annex is awesome
and so are you

;-)

But bloody hell, it's hard to get this thing to build. As you've mentioned earlier, building on Debian 7 isn't supported anymore, so I installed Debian 8.3 yesterday for the sole purpose of compiling git-annex, but still no luck:

[32 of 32] Compiling Main             ( dist/setup/setup.hs, dist/setup/Main.o )
Linking ./dist/setup/setup ...
unrecognized option `--extra-prog-path=/home/sunny/.cabal/bin'
Makefile:19: recipe for target 'Build/SysConfig.hs' failed
make: *** [Build/SysConfig.hs] Error 1

I was hoping to get it to build so I could find the exact commit that introduced this, and also provide some patches with some functionality I've been thinking of. Is building on Debian 8.3 (jessie) supported? I found a bug report from you on https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=778987 that seems to be related, but I don't know if that's the case. The newest version I'm able to build is 5.20150219, somewhere after that various things start to fail.

fixed; I found a way to isolate the test suite from global git configs, by setting GIT_CONFIG_NOSYSTEM and also setting HOME and XDG_CONFIG_HOME to an empty directory. --Joey
