.SH DESCRIPTION
.B dgit
treats the Debian archive as a version control system, and
bidirectionally gateways between the archive and git. The git view of
the package can contain the usual upstream git history, and will be
-augmented by commits representing uploads done without using dgit.
-This git history is stored in a canonical location
+augmented by commits representing uploads done by other developers not
+using dgit. This git history is stored in a canonical location known
+as
.B dgit-repos
-which lives outside the Debian archive.
+which lives outside the Debian archive (currently, on Alioth).
.B dgit clone
and
.B dgit fetch
consult the archive and dgit-repos and fetch and/or construct the
git view of the history. With clone, the destination directory (by
-default, the package name in the current directory) will be created.
+default, the package name in the current directory) will be created,
+and the new directory's `origin' remote will be set up to point to
+the package's dgit-repos tree.
.B dgit build
runs
You may use any suitable git workflow with dgit, provided you
satisfy dgit's requirements:
+dgit maintains a pseudo-remote called
+.BR dgit ,
+with one branch per suite. This remote cannot be used with
+plain git.
+
The
.B dgit-repos
-repository for each package contains one branch per suite named
-\fBdgit/\fR\fIsuite\fR. These should be pushed to only by
+repository for each package contains one ref per suite named
+\fBrefs/dgit/\fR\fIsuite\fR. These should be pushed to only by
dgit. They are fast forwarding. Each push on this branch
corresponds to an upload (or attempted upload).
+However, it is perfectly fine to have other branches in dgit-repos;
+normally the dgit-repos repo for the package will be accessible via
+the remote name `origin'.
+
dgit push can operate on any commit which is a descendant of the
current dgit/suite tip in dgit-repos.
Uploads made by dgit contain an additional field
-.B Vcs-Git-Master
+.B Vcs-Dgit-Master
in the source package .dsc. (This is added by dgit push.)
This specifies a commit (an ancestor of the dgit/suite
branch) whose tree is identical to the unpacked source upload.
.TP
.BR --dry-run | -n
Go through the motions, fetching all information needed, but do not
-actually update the output(s). For fetch and pull, dgit determines
-which git commit corresponds to the archive but does not update
-remotes/dgit/dgit/suite or do any merge. For push, dgit does
+actually update the output(s). For push, dgit does
the required checks and leaves the new .dsc in a temporary file,
but does not sign, tag, push or upload.
.TP
.BR --no-sign
does not sign tags or uploads (meaningful only with push).
.TP
+.TP
+.BI -p package
+Specifies that we should process source package
+.I package
+rather than looking in debian/control or debian/changelog.
+Valid with dgit fetch and dgit pull, only.
+.TP
.BI -D
-Spew debugging information to stderr.
+Prints debugging information to stderr. Repeating the option produces
+more output (currently, up to -DD is meaningfully different).
.TP
.BI -c name = value
Specifies a git configuration option. dgit itself is also controlled
.BI -C changesfile
Specifies the .changes file which is to be uploaded. By default
dgit push looks for single .changes file in the parent directory whose
-filename suggests they it is for the right package and version.

+.SH CONFIGURATION

.SH BUGS
-dgit is not nearly configurable enough. The locations for dgit-repos
-(on alioth) and for the Debian archive are currently hardcoded.
-There is not yet any support for suites which are in different
-distributions to Debian.
+We should be using some kind of vhost/vpath setup for the git repos on
+alioth, so that they can be moved later if and when this turns out to
+be a good idea.
-dgit will only work with packages in main. The madison http query API
-does not give the component.
+Debian Policy needs to be updated to describe the new Vcs-Dgit-Master
+field (and to specify that it is an RC bug for that field to refer
+to an unavailable commit).
-dgit assumes knowledge of the archive layout. There appears to be no
-sane way to find the path in the archive pool of the .dsc for a
-particular suite.
+dgit cannot currently introduce a package into a suite.
+
+dgit push should perhaps do `git push origin', or something similar,
+by default.
The mechanism for checking for and creating per-package repos on
alioth is a hideous bodge. One consequence is that dgit currently
currently any mechanism for determining and honouring the archive's
ideas about access control. Currently only DDs can push.
-dgit's representation of format `3.0 (quilt)' source packages (even if
-they were supported) would not represent the patch stack. Currently
-the patch series representation cannot round trip through the archive.
-Ideally dgit would represent a quilty package with an origin commit of
-some kind followed by the patch stack as a series of commits followed
-by a pseudo-merge (to make the branch fast-forwarding). This would
-also mean a new `dgit rebase-prep' command or some such to turn such a
-fast-forwarding branch back into a rebasing patch stack, and a `force'
-option to dgit push (perhaps enabled automatically) which will make
-the required pseudo-merge.

+which will make the required pseudo-merge.
dgit's handling of .orig.tar.gz is not very sophisticated. Ideally
the .orig.tar.gz could be transported via the git repo as git tags.
+Doing this is made more complicated by the possibility of a `3.0
+(quilt)' package with multiple .orig tarballs.
The error messages are often unhelpfully terse and tend to refer to
line numbers in dgit.
The option parser requires values to be cuddled to the option name.

+dgit assumes knowledge of the archive layout. There appears to be no

+`well known algorithm' by now.
+
+--dry-run often does not work with fetch, even though this is a
+logically plausible request. (It fails, instead.)
