If a git repository is non-bare, and core.worktree is not set, git
tries to deduce the worktree. This deduction is not always helpful, e.g.
% git --git-dir=$HOME/.nmbug clean -f
would likely delete most of the files in the current directory

With two branches getting fetched (master and config), the branch
referenced by FETCH_HEAD is ambiguous. For example, I have:
$ cat FETCH_HEAD
41d7bfa7184cc93c9dac139d1674e9530799e3b0 \
not-for-merge branch 'config' of http://nmbug.tethera.net/git/nmbug-tags
acd379ccb973c45713eee9db177efc530f921954 \
not-for-merge branch 'master' of http://nmbug.tethera.net/git/nmbug-tags
(where I wrapped the line by hand). This means that FETCH_HEAD
references the config branch:
$ git rev-parse FETCH_HEAD
41d7bfa7184cc93c9dac139d1674e9530799e3b0
which breaks all of the FETCH_HEAD logic in nmbug (where FETCH_HEAD is
assumed to point to the master branch).
Instead of relying on FETCH_HEAD, use @{upstream} as the
remote-tracking branch that should be merged/diffed/integrated into
HEAD. @{upstream} was added in Git v1.7.0 (2010-02-12) [1], so
relying on it should be fairly safe. One tricky bit is that bare
repositories don't set upstream tracking branches by default:
$ git clone --bare http://nmbug.tethera.net/git/nmbug-tags.git nmbug-bare
$ cd nmbug-bare
$ git remote show origin
* remote origin
Fetch URL: http://nmbug.tethera.net/git/nmbug-tags.git
Push URL: http://nmbug.tethera.net/git/nmbug-tags.git
HEAD branch: master
Local refs configured for 'git push':
config pushes to config (up to date)
master pushes to master (up to date)
While in a non-bare clone:
$ git clone http://nmbug.tethera.net/git/nmbug-tags.git
$ cd nmbug-tags
$ git remote show origin
* remote origin
Fetch URL: http://nmbug.tethera.net/git/nmbug-tags.git
Push URL: http://nmbug.tethera.net/git/nmbug-tags.git
HEAD branch: master
Remote branches:
config tracked
master tracked
Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (up to date)
From the clone docs [2]:
--bare::
Make a 'bare' Git repository…
Also the branch heads at the remote are copied directly
to corresponding local branch heads, without mapping
them to `refs/remotes/origin/`. When this option is
used, neither remote-tracking branches nor the related
configuration variables are created.
To use @{upstream}, we need to the local vs. remote-tracking
distinction, so this commit adds 'nmbug clone', replacing the
previously suggested --bare clone with a non-bare --no-checkout
--separate-git-dir clone into a temporary work directory. After
which:
$ git rev-parse @{upstream}
acd379ccb973c45713eee9db177efc530f921954
gives us the master-branch commit. Existing nmbug users will have to
run the configuration tweaks and re-fetch by hand. If you don't have
any local commits, you could also blow away your NMBGIT repository and
re-clone from scratch:
$ nmbug clone http://nmbug.tethera.net/git/nmbug-tags.git
Besides removing the ambiguity of FETCH_HEAD, this commit allows users
to configure which upstream branch they want nmbug to track via 'git
config', in case they want to change their upstream repository.

Current code does not distinguish between an empty string in the
NMBPREFIX environment variable and the variable being undefined. This
makes it impossible to define an empty prefix, if, e.g. somebody wants
to dump all of their tags with nmbug.

This is at least easier to understand than the magic hash. It may also
be a bit more robust, although it is hard to imagine these numbers
changing without many other changes in git.

This should be more robust with respect to tags with whitespace and
and other special characters. It also (hopefully) fixes a remaining
bug handling message-ids with whitespace. It should also be
noticeably faster for large sets of changes since it does one exec per
change set as opposed to one exec per tag changed.

This should make nmbug tolerate tags with whitespace and other special
characters it. At the moment this relies on _not_ passing calls to
notmuch tag through the shell, which is a documented feature of perl's
system function.
|

There seems to be consensus to use presence in contrib as
documentation of limited support by the notmuch developers; in fact
nmbug is pretty integrated into our current development process, so
devel seems more appropriate.
