git-annex: fix #36309

Seems to be failing to build: http://bot.brew.sh/job/Homebrew%20Pull%20Requests/20552/version=yosemite/testReport/junit/brew-test-bot/yosemite/install_git_annex/

[psibre]

From trying to build git-annex from source in the past, I know that it's utterly volatile -- dependency hell with cabal etc. Which is why I cherish the fact that homebrew has it bottled! =)

Trying to build like the bot on a clean system fails for me even without this patch, i.e., at the latest upstream revision (4bb9eb8). So I'm pretty sure it's not due to adding the depends_on "quvi" stanza:

Having said all that, git-annex does have a compile time dependency on quvi (see +quvi flag above); what I was trying accomplish with my pull request was simply to make homebrew also install quvi when installing the git-annex bottle.

[MikeMcQuaid]

Yeh. I don't mind just adding the dependency but if we can get this green first that'd be great too.

[psibre]

Some of the Haskell library skew with aws has resolved itself overnight. However, now the build fails down the line...

Building feed-0.3.9.2...
Preprocessing library feed-0.3.9.2...

Text/Feed/Import.hs:35:8:
    Could not find module ‘System.IO.UTF8’
    Use -v to see a list of the files searched for.

It seems like the only way to build git-annex is to keep trying daily until the dependency hell with cabal sorts itself out...
Is there a way to periodically restart the CI build until it passes and builds the bottles?

[MikeMcQuaid]

Is there a way to periodically restart the CI build until it passes and builds the bottles?

Nope but if you ask me I can kick it off periodically.

[MikeMcQuaid]

Still borked :(

[psibre]

Yeah, confirmed. Haskell may be a fantastic language (or so I've read), but their dependency resolution engine is fundamentally broken.
It seems that we have to wait for feed to be updated since its utf8-string was updated last week and breaks compatibility...

[carlmod]

As git-annex was updated again, it would probably make sense to update the pullrequest to the new version.

url "https://hackage.haskell.org/package/git-annex-5.20150205/git-annex-5.20150205.tar.gz"
sha1 "5df6114cb029531e429e2b423f5ae7f755ffa390"

It does still not build, but it seems feed has a pullrequest that should fix it sof/feed#10.
