My article Dissecting The Myth That Open Source Software Is Not Commercial is now up at the IEEE Software Blog. (Comments over there, please, not here.)

It’s gotten a surprising amount of Twitter activity, which is pleasing. The article’s message is one I’d like to see spread widely!

Many thanks to editor Stefano Zacchiroli for editing, and for suggesting an article in the first place.

If you encountered this error when trying to clone the Redis repository from GitHub recently, there is a solution. The error looks like this:

  $ git clone https://github.com/antirez/redis
  Cloning into 'redis'...
  remote: Counting objects: 42713, done.        
  remote: Compressing objects: 100% (33/33), done.        
  remote: Total 42713 (delta 15), reused 0 (delta 0), pack-reused 42680        
  Receiving objects: 100% (42713/42713), 19.29 MiB | 6.81 MiB/s, done.
  error: object 1f9ef1b6556b375d56767fd78bf06c7d90e9abea: \
  zeroPaddedFilemode: contains zero-padded file modes
  fatal: Error in object
  fatal: index-pack failed
  $

The problem is that your ~/.gitconfig file probably has this setting:

  [transfer]
          fsckObjects = true

…and/or perhaps these settings:

  [fetch]
          fsckobjects = true
  [receive]
          fsckObjects = true 

Solution: set the value(s) to false while you clone Redis, then set them back to true afterwards.

See also this discussion for more; that’s where I originally stumbled across the solution. I’ve now cross-linked between this post and a ticket in the Redis issue tracker.

Pro non-tip: you might think that running

  $ git config --global fsck.zeroPaddedFilemode ignore

so as to get

  [fsck]
  	zeroPaddedFilemode = ignore

in your .gitconfig would solve this problem in a nice targeted way, but it won’t, so don’t bother. See here for some discussion about that.

(This post is part of my SOLVED as a Service series, in which I post solutions to technical problems with open source software that I use. The point is the next time I encounter the same problem and do an Internet search, my own post will come up; this has now actually happened several times. If these posts help others, that’s a bonus.)
