bug report, error : Unable to find 000000000.....

[Jeremy Sw]

By running  # git clone http://intellinuxwireless.org/repos/ipwraw.git
git return an error when trying to Get alternates list.
the error is :
"error: Unable to find 0000000000000000000000000000000000000000 under http://intellinuxwireless.org/repos/ipwraw.git/
Cannot obtain needed object 0000000000000000000000000000000000000000"
apparently caused by a weird architecture of the tree !
there is 4 or 5 diffrents projects, but they have commun files because firmwares are related !

I suggested on IRC to try this (I reproduced the error)

mkdir test && cd test && \
git-init && \
git fetch http://intellinuxwireless.org/repos/ipwraw.git master:master

and it works. Ok, fist I thought the error is in another branch, but

git-ls-remote http://intellinuxwireless.org/repos/ipwraw.git
7e85b2032a864fcfe489085b768eea4b3a3a9d0b        refs/heads/master
7e85b2032a864fcfe489085b768eea4b3a3a9d0b        refs/heads/origin
7e85b2032a864fcfe489085b768eea4b3a3a9d0b        refs/tags/ipwraw-0.0.1
7e85b2032a864fcfe489085b768eea4b3a3a9d0b        refs/tags/ipwraw-0.0.2

there is no other branch, at least as I could see.

The repository is seriously broken.  If you try wget to see
refs/tags/* files, you will find out that they are not even
tags; they are symrefs and both point at the master branch.

I do not think the Porcelain-ish shipped with git creates symref
in refs/tags/, so it was done by somebody playing with symbolic-ref
by hand perhaps?

I'd suggest James to do delete these bogus refs/tags/* files and
tag the correct commit with "git tag".

The above does explain the breakage.  The script that created snapshot 
tarballs for ipwraw was written was copying .git/HEAD to the tag name in 
.git/refs/tags... at some point .git/HEAD changed from being an actual 
symlink to master to being a normal file containing 'ref: refs/heads/master'

I believe I have fixed it now.

Thanks,
James
