Hi Trevor,

For folks that want to start versioning a new tag-space, instead of
cloning one that someone else has already started.
The empty-blob hash-object call avoids errors like:
$ nmbug commit
error: invalid object 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 for
'tags/...'
fatal: git-write-tree: error building trees
'git HASH(0x9ef3eb8) write-tree' exited with nonzero value
David Bremner suggested [1]:
$ git hash-object -w /dev/null
instead of my Python version of:
$ git hash-object -w --stdin -
but I expect that closing stdin is more portable than the /dev/null
path (which doesn't exist on Windows, for example).

The only change since v2 [1] is a commit-message tweak:
* Mention Windows as an OS with stdin but no /dev/null [2].
Cheers,
Trevor

Why do you create a non-bare repository and then make it bare? Before I
discovered this patch, I created the nmbug repository by hand and it was
possible to do it with bare repo from beginning. The following code
seems to work and is a bit simpler:
def init(remote=None):
Create an empty nmbug repository.
This wraps 'git init' with a few extra steps to support subsequent
status and commit commands.
_spawn(
args=['git', '--git-dir', NMBGIT, 'init', '--bare'],
wait=True)
# create an empty blob (e69de29bb2d1d6434b8b29ae775ad8c2e48c5391)
_git(args=['hash-object', '-w', '--stdin'], input='', wait=True)
_git(
args=[
'commit', '--allow-empty', '-m', 'Start a new nmbug repository'
],
additional_env={'GIT_WORK_TREE': NMBGIT},
wait=True)
Note that in the initial commit I set the work tree to NMBGIT. This is
because 'git commit' needs some work tree, but in our case it doesn't
matter which one because the commit is empty.
