"Empty archive" error when install formulas with tar.xz archives, after upgrading to Xcode 8

[zhouyan]

I have just upgraded to Xcode 8 and run xcode-select --install after the upgrading. I tried to reinstall all formulas I had. And I encountered errors as the following, for example, when installing git,

$ brew install git --verbose
==> Using the sandbox
/usr/bin/sandbox-exec -f /tmp/homebrew20160915-13630-1k3cym9.sb nice /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -W0 -I /usr/local/Library/Homebrew -- /usr/local/Library/Homebrew/build.rb /usr/local/Library/Taps/homebrew/homebrew-core/Formula/git.rb --verbose
==> Downloading https://www.kernel.org/pub/software/scm/git/git-2.10.0.tar.xz
Already downloaded: /Users/Zhou/Library/Caches/Homebrew/git-2.10.0.tar.xz
==> Verifying git-2.10.0.tar.xz checksum
Error: Empty archive

This error only happens with formulas using a source packed as tar.xz instead of gz or bz2. I tried to manually uncompress the package via tar xf and it works fine.

Try to brew uninstall --force xz.

[zhouyan]

I already tried that before submiting this issue. xz just got reinstalled back as a dependencies for those formulas and the same issue persists.

Can you install the CLT, then brew reinstall xz, and try again? This is a problem caused by having Xcode 8 on 10.11 without the CLT, which we'll be adding a warning for (#965).

[zhouyan]

Both were done. The first thing I did was to install CLT even before I try to do anything with brew.

What happens if you run xz on the commandline?

[zmwangx]

Or just brew test xz.

[zhouyan]

brew test xz fail with the following

$ brew test xz

However, uncompress seems to work just fine. For example cd ~/Library/Cache/Homebrew; tar xf whatever.tar.xz works just fine.

[zmwangx]

Your /usr/bin/tar has nothing to do with brewed xz.

Typical Xcode 8 on El Cap debacle.

Please pour our bottle in the meantime rather than compile from source.

[zhouyan]

OK, I guess I have just to wait a few more days for the new OS. It sounds like Xcode 8 on Sierra is better and it is only a problem of Xcode 8 on Ei Cap

[zmwangx]

Here's some background reading: Homebrew/homebrew-core#4809 (comment).

And #970 will hopefully fix the problem.

[zmwangx]

I guess I have just to wait a few more days for the new OS.

By the way, be advised that if you need anything on this list you'd better hold out a little longer.

[DomT4]

Anyone impacted should brew reinstall xz. This should be fixed by ILZ's sterling work in #970, but you'll need to reinstall the broken xz.
