dgit: dpkg_source_ignores: Exclude the right set of things

Change the dpkg-source -i argument to exclude exactly the right set of
things.  (Sadly this is not a simple rune.)

Previously we might exclude `foo.git', for example !

dgit: Properly shellquote --git-builder argument to gbp

This is about to contain more exciting shell metacharacters.
(Even now, it is wrong without quoting as we end up telling gbp to
pass -i.git/ rather than -i\.git/ to dpkg-source.)

dgit: print-dpkg-source-ignores action

New print-dpkg-source-ignores option to print the big rune you need to
pass to dpkg-source to make it work exactly the right.

test suite: dpkgsourceignores-docs: Check dgit-maint-merge(7) -i -I rune

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

dgit-maint-merge(7): Add ' ' around -i\.git/

This manpage should present a shell rune, not a half-quoted thing
whose interpretation is left as a tricky exercise to othe reader.

The ' ' protect the \ so that it would actually get passed to
dpkg-buildpackage.

dgit-maint-merge(7): Reformat slightly

Introduce semantic newlines around the dpg-buildpackage -i -I
rune.  This will make it easier to test.

dgit: Break out -i -I rune into a variable

There is also an instance in dgit-maint-merge.7.pod but that's

test suite: stunt gnupg runs gpg again if it exits status 2

Work around gnupg agent connection races by having our stunt gpg
wrapper simply try running gpg again, once, if it exits 2.
This does not fully suppress the bug but it does significantly reduce
the probability.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

test suite: Tolerate worktrees when trying to git-fsck

A `git worktree' has a file for .git.  We still want to fsck them.  We
can simply run the fsck in the directory containing .git, instead.
That works for ordinary trees with a .git directory, and for
worktrees.

directory refactor: open_main_gitattrs confesses if $maindir not set

This improves the error message considerably for "didn't call
record_maindir" bugs.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

worktree support: dgit: Fix for .git/logs/refs/

Experimentally, both the common dir and the worktree's git dir have a
.git/logs.  But, as might be expected, the worktree's one has the
reflog for its HEAD and not any of the refs/ reflogs.

Implicitly, we are deciding here that the dgit quilt cache is shared
between all worktrees.  That seems fine.  I think we don't ever rely
on its actual current value, so even concurrent dgit runs ought to be
fine.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

worktree support: dgit: Fix for .git/info/attributes

Experimentally, this file is in the common dir, not the per-worktree
dir.  Honour $maindir_gitcommon everywhere.

Rename `open_main_gitattrs'.  Previously it could in theory be used in
the playtree (but, it isn't).  Now it always operates on the main
tree.

Indeed, as we require, the `setup' stuff is only done in the main
tree.  The gitattributes fixes for playtrees are done,
unconditionally, with the much simpler hammer in playtree_setup.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

worktree support: Fix playtree_setup

In a worktree, .git is not a directory.  We need to use
$maindir_common.  Add a comment, too.

directory handling: dgit: Introduce dgit_privdir and use it

test suite: sbuild-gitish: Insist on using "build" chroot

In "test suite: sbuild-gitish: Find sbuild rune in the manpage" aka
f5c0d33ede8a we accidentally switched from "build" to "jessie".
Randomly messing about with the user's "jessie" chroot is not very
nice.  (And it would break in a hypothetical formal test providing the
x-dgit-schroot-build capability.)

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

worktree support: Fix ensure_a_playground (gives absolute path now)

Make it honour $maindir_gitdir so it will DTRT in a `git worktree'.
The .git/dgit play area ends up in the .git/worktrees/<worktreename>
for this worktree.

It now returns an absolute path.  The only call site that needs
adjusting is the one in fresh_playground.

directory refactoring: dgit clone: call record_maintree in multisuite too

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

directory refactoring: dgit clone: call record_maintree

We are making up our own tree, here.  We will need to call
record_maintree in case we need to use information which it obtains.
Currently, we don't.

But git worktrees are complicated: we are going to have to depend on
the new $maindir_git* variables, in setup_new_tree.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

directory refactoring: most invocations: call record_maintree

We need to call record_maintree so that $maindir and its friends are
set, since we're going to rely on them heavily.  Most operations will
need them.

Any operation that is invoked in a git tree should definitely have
this called.
