Bitcoin-core is failing

[christopherkeller]

Installation fails before the package gets installed in the Caskroom directory, but opening it manually and dragging and dropping in /Applications seems to work just fine.

[rolandwalker]

Hi! Thanks for the report!

This is similar to some other reports we have seen lately, and is likely an unintended downstream consequence of #8089. I plan to look into this tomorrow.

[rolandwalker]

@christopherkeller could you post the output of brew cask doctor ?

[rolandwalker]

==> Executing: ["/usr/bin/hdiutil", "imageinfo", "#"] ==> Using container class Hbc::Container::Dmg for /Library/Caches/Homebrew/bitcoin-core-0.10.0.dmg

@phinze, @radeksimko, @ndr-qef, @claui (if you are around) I can't duplicate this issue, and it seems like more than one thing is going wrong simultaneously on the user's system, which makes it tough to reason out. Suggestions welcome.

The debug output quoted above indicates that the correct hdiutil command did run (the argument wasn't really #). That suggests something is wrong with inspect. We actually called utf8_inspect here which was a workaround for Ruby UTF-8 oddities. We also preserved a monkeypatch on inspect from Homebrew which is likely intended to address the same issue.

And all of that would seem to be irrelevant to why the point of failure would be xattr. I do have some memory that xattr just happens to be the point in the process at which a permissions problem can sometimes manifest itself.

And, the exit status in the user's output is also rendered as #. That's not a Pathname, but should be a Process::Status instance, and is rendered with plain inspect

[tapeinosyne]

For what is worth, I could reproduce in both my Mavericks and Yosemite VMs (which is why I labelled the issue). However, my inspect output is fine.

Interestingly, cursory testing failed to find another :target cask which fails on xattr.

[tapeinosyne]

Printing stderr suggests permission issues, as @rolandwalker guessed:

==> Executing: ["/usr/bin/xattr", "-w", "com.apple.metadata:kMDItemAlternateNames", "(\\\"Bitcoin Core.app\\\")", "#<Pathname:/Applications/Bitcoin Core.app>"]
==> xattr: [Errno 13] Permission denied: '/Applications/Bitcoin Core.app'

[christopherkeller]

Permissions are possible I suppose, but it still fails if I install the symlink to /tmp via --appdir. Additionally, I can create files under /Applications via the command liine.

$ touch /Applications/foo
$ ls -l /Applications/foo
-rw-r--r--  1 macadmin  admin  0 Feb 21 13:51 /Applications/foo
$ rm /Applications/foo

[rolandwalker]

Thanks @christopherkeller!

We also confirmed in IRC that there are two apparently unrelated problems. The xattr error can happen without the inspect output mangling.

[SuperHenkie]

I recently ran into the same issue. Is there anything I can do to get bitcoin-core cask installer working?

[deizel]

Unfortunately, this is still an issue today it seems.

[radeksimko]

I just managed to reproduce that problem too in my Yosemite VM.

As mentioned above, permissions are really the reason:

==> Executing: ["/usr/bin/xattr", "-w", "com.apple.metadata:kMDItemAlternateNames", "(\"Bitcoin Core.app\")", "#<Pathname:/Users/vagrant/Applications/Bitcoin Core.app>"] ==> xattr: [Errno 13] Permission denied: '/Users/vagrant/Applications/Bitcoin Core.app'

this is output from ls -la:

lrwxr-xr-x 1 vagrant staff 62 May 14 00:14 /Users/vagrant/Applications/Bitcoin Core.app -> /opt/homebrew-cask/Caskroom/bitcoin-core/0.10.1/Bitcoin-Qt.app

and now :tada: surprise surprise, output from ls -la /opt/homebrew-cask/Caskroom/bitcoin-core/0.10.1/:

total 40
drwxr-xr-x  6 vagrant  staff    204 May 14 00:19 .
drwxr-xr-x  3 vagrant  staff    102 May 14 00:19 ..
-r-xr-xr-x  1 vagrant  admin  15364 May 31  2013 .DS_Store
dr-xr-xr-x  3 vagrant  admin    102 May 31  2013 .background
lrwxr-xr-x  1 vagrant  admin     13 May 14 00:19 Applications -> /Applications
dr-xr-xr-x  3 vagrant  admin    102 May 31  2013 Bitcoin-Qt.app

so as you can see, Bitcoin-Qt.app is shipped with r-xr-xr-x permissions, which means that even the owner cannot write into the file.

I managed to fix it like this:

diff --git a/lib/hbc/artifact/symlinked.rb b/lib/hbc/artifact/symlinked.rb
index bcaa1a3..2c57fa8 100644

I will send a PR soon.

This patch works for me on a real Yosemite install - nice find! :clap:

[rxacevedo]

The above patch solves the issue for me as well - thanks! :+1:

[deizel]

FYI - still waiting on the patch to be merged (#11200). The temporary fix is to apply the patch manually.

[vitorgalvao]

Yes, I’m aware.

[deizel]

:+1:

[jawshooah]

11200 has been merged. Expect a new release with the fix later this evening.

[wkentaro]

I might have same problem, even after updating homebrew-cask.
