.SH DESCRIPTION
.B dgit
treats the Debian archive as a version control system, and
.B dgit-repos
which lives outside the Debian archive (currently, on Alioth).
-.B dgit clone
+The usual workflow is: 1. clone or fetch; 2. make and commit changes
+in git as desired; 3. run dgit build, dgit sbuild or dgit
+build-source, or generate the source and binary packages for upload
+some other way; 4. do pre-upload tests of the proposed upload; 5. run
+dgit push.
+.TP
+\fBdgit clone\fR \fIpackage\fP [\fIsuite\fP] [\fB./\fP\fIdir|\fB/\fP\fIdir\fR]
+Consults the archive and dgit-repos to construct the git view of
+history for
+.I package
+in
+.I suite
+.RB ( sid
+by default)
+in a new directory (named
+.BI ./ package
+by default);
+also, downloads any necessary orig tarballs.
+
+The suite's git tip is
+left on the local branch
+.BI dgit/ suite
+ready for work, and on the corresponding dgit remote tracking branch.
+Also, the
+.B origin
+remote will be set up to point to the package's dgit-repos tree
+for the distro to which
+.I suite
+belongs.
+.TP
+\fBdgit fetch\fR [\fIsuite\fP]
+Consults the archive and git-repos to update the git view of
+history for a specific suite (and downloads any necessary orig
+tarballs), and updates the remote tracking branch
+.BR remotes/dgit/dgit/ \fIsuite\fR.
+If the current branch is
+.BI dgit/ suite
+then dgit fetch defaults to
+.IR suite ;
+otherwise it parses debian/changelog and uses the suite specified
+there.
+.TP
+\fBdgit pull\fR [\fIsuite\fP]
+Does dgit fetch, and then merges the new head of the remote tracking
+branch
+.BI remotes/dgit/dgit/ suite
+into the current branch.
+.TP
+\fBdgit build\fR ...
+Runs
+.B dpkg-buildpackage
+with some suitable options. Options and argumments after build
+will be passed on to dpkg-buildpackage. It is not necessary to use
+dgit build when using dgit; it is OK to use any approach which ensures
+that the generated source package corresponds to the relevant git
+commit.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit build-source\fR ...
+Builds the source package, and a changes file for a prospective
+source-only upload, using
+.BR dpkg-source .
+The output is left in
+.IR package \fB_\fR version \fB.dsc\fR
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,
-and the new directory's `origin' remote will be set up to point to
-the package's dgit-repos tree.
-
-.B dgit build
-runs
+.IR package \fB_\fR version \fB_source.changes\fR.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+.B dgit help
+Print a usage summary.
+.TP
+\fBdgit sbuild\fR ...
+Constructs the source package, uses
+.B sbuild
+to do a binary build, and uses mergechanges to merge the source and
+binary changes files. Options and argumments after sbuild will be
+passed on to sbuild. Changes files matching
+.IB package _ version _*.changes
+in the parent directory will be removed; the output is left in
+.IR package \fB_\fR version \fB_multi.changes\fR.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit git-build\fR ...
+Runs
.B git-buildpackage
-with some suitable options. Options after
-.B build
-will be passed on to git-buildpackage. It is not necessary to
-use dgit build; it is OK to use any approach which ensures that
-the generated source package corresponds to the relevant git commit.
-Tagging and signing should be left to dgit push.
-
-.B dgit push
-does an `upload', pushing the current HEAD to the archive (as a source
-package) and to dgit-repos (as git commits). This also involves
-making a signed git tag, and signing the files to be uploaded to the
-archive.
-.SH MODEL AND WORKFLOW
-You may use any suitable git workflow with dgit, provided you
-satisfy dgit's requirements:
+with some suitable options. Options and argumments after git-build
+will be passed on to git-buildpackage.
-dgit maintains a pseudo-remote called
-.BR dgit ,
-with one branch per suite. This remote cannot be used with
-plain git.
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit push\fR [\fIsuite\fP]
+Does an `upload', pushing the current HEAD to the archive (as a source
+package) and to dgit-repos (as git commits). The package must already
+have been built ready for upload, with the .dsc and .changes
+left in the parent directory.
-The
-.B dgit-repos
-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).
+In more detail: dgit push checks that the current HEAD corresponds to
+the .dsc. It then pushes the HEAD to the suite's dgit-repos branch,
+makes a signed git tag, edits the .dsc to contain the dgit metadata
+field, runs debsign to sign the upload (.dsc and .changes), pushes the
+signed tag, and finally uses dput to upload the .changes to the
+archive.
-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 always uses the package, suite and version specified in the
+debian/changelog and the .dsc, which must agree. If the command line
+specifies a suite then that must match too.
-dgit push can operate on any commit which is a descendant of the
-current dgit/suite tip in dgit-repos.
+If dgit push fails while uploading, it is fine to simply retry the
+dput on the .changes file at your leisure.
+.TP
+\fBdgit rpush\fR \fIbuild-host\fR\fB:\fR\fIbuild-dir\fR [\fIpush args...\fR]
+Pushes the contents of the specified directory on a remote machine.
+This is like running dgit push on build-host with build-dir as the
+current directory; however, signing operations are done on the
+invoking host. This allows you to do a push when the system which has
+the source code and the build outputs has no access to the key.
-Uploads made by dgit contain an additional field
-.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.
+However, the build-host must be able to ssh to the dgit repos. If
+this is not already the case, you must organise it separately, for
+example by the use of ssh agent forwarding.
-Uploads not made by dgit are represented in git by commits which are
-synthesised by dgit. The tree of each such commit corresponds to the
-unpacked source; the single parent is the last known upload - that is,
-the contents of the dgit/suite branch.
+The remaining arguments are treated just as dgit push would handle
+them.
-dgit expects repos that it works with to have a
-.B dgit
-remote. This refers to the well-known dgit-repos location
-(currently, the dgit-repos project on Alioth). dgit fetch updates
-the remote tracking branch for dgit/suite.
+build-host and build\-dir can be passed as separate
+arguments; this is assumed to be the case if the first argument
+contains no : (except perhaps on in [ ], to support IPv6 address
+literals).
+.TP
+.B dgit quilt-fixup
+Looks to see if the tree is one which dpkg-source cannot properly
+represent. If it isn't, dgit will fix it up for you (in quilt terms,
+by making a new debian/ patch containing your unquilty changes) and
+make a commit of the changes it has made.
+
+This is normally done automatically by dgit build and dgit push.
+.TP
+.B dgit version
+Prints version information and exits.
.SH OPTIONS
.TP
.BR --dry-run | -n
the required checks and leaves the new .dsc in a temporary file,
but does not sign, tag, push or upload.
.TP
+.BR --damp-run | -L
+Go through many more of the motions: do everything that doesn't
+involve either signing things, or making changes on the public
+servers.
+.TP
.BI -k keyid
Use
.I keyid
rather than looking in debian/control or debian/changelog.
Valid with dgit fetch and dgit pull, only.
.TP
+.BR --clean=git | -wg
+The source tree should be cleaned, before building a source package
+with one of the build options, using
+.BR "git clean -xdf" .
+This will delete all files which are not tracked by git.
+.TP
+.BR --clean=none | -wn
+Do not clean the tree before building a source package. If there are
+files which are not in git, a subsequent dgit push will fail.
+.TP
+.BR --clean=dpkg-source | -wd
+Use dpkg-buildpackage to do the build, so that the source package
+is cleaned by dpkg-source running the package's clean target.
+This is the default. It requires the package's build dependencies.
+.TP
.BR -N | --new
The package may be new in this suite. Without this, dgit will
refuse to push.
.TP
+.BR --ignore-dirty
+Do not complain if the working tree does not match your git HEAD.
+This can be useful with build, if you plan to commit later. (dgit
+push will still ensure that the .dsc you upload and the git tree
+you push are identical, so this option won't make broken pushes.)
+
+This option may not work properly on `3.0 (quilt)' packages, as in
+that case dgit needs to use and perhaps commit parts of your working
+tree.
+.TP
+.BR --no-quilt-fixup
+Do not fix up source format `3.0 (quilt)' metadata. If you use this
+option and the package did in fact need fixing up, dgit push will
+fail.
+.TP
.BI -D
Prints debugging information to stderr. Repeating the option produces
more output (currently, up to -DD is meaningfully different).
Specifies a git configuration option. dgit itself is also controlled
by git configuration options.
.TP
-.RI \fB--dget=\fR program |\fB--dput=\fR program |\fB--debsign=\fR program
-Specifies alternative programs to use instead of dget, dput
-or debsign.
+.RI \fB-v\fR version "|\fB_\fR | " \fB--since-version=\fR version |\fB_\fR
+Specifies the
+.BI -v version
+option to pass to dpkg-genchanges, during builds. Changes (from
+debian/changelog) since this version will be included in the built
+changes file, and hence in the upload. If this option is not
+specified, dgit will query the archive and use the latest version
+uploaded to the intended suite.
+
+Specifying
+.B _
+inhibits this, so that no -v option will be passed to dpkg-genchanges
+(and as a result, only the last stanza from debian/changelog will
+be used for the build and upload).
+.TP
+.RI \fB-m\fR maintaineraddress
+Passed to dpkg-genchanges (eventually).
+.TP
+.RI \fB--ch:\fR option
+Specifies a single additional option to pass, eventually, to
+dpkg-genchanges.
+.TP
+.RI \fB--dget=\fR program |\fB--dput=\fR program |...
+Specifies alternative programs to use instead of
+.BR dget ,
+.BR dput ,
+.BR debsign ,
+.BR dpkg-source ,
+.BR dpkg-buildpackage ,
+.BR dpkg-genchanges ,
+.BR sbuild ,
+.BR gpg ,
+.BR ssh ,
+.BR dgit ,
+or
+.BR mergechanges .
+
+For dpkg-buildpackage, dpkg-genchanges, mergechanges and sbuild,
+this applies only when the program is invoked directly by dgit.
+
+For dgit, specifies the command to run on the remote host when dgit
+rpush needs to invoke a remote copy of itself. (dgit also reinvokes
+itself as the EDITOR for dpkg-source --commit; this is done using
+argv[0], and is not affected by --dget=).
+
+For ssh, the default value is taken from the
+.B DGIT_SSH
+or
+.B GIT_SSH
+environment variables, if set (see below). And, for ssh, when accessing the
+archive and dgit-repos, this command line setting is overridden by the
+git config variables
+.BI dgit-distro. distro .ssh
+and
+.B .dgit.default.ssh
+(which can in turn be overridden with -c). Also, when dgit is using
+git to access dgit-repos, only git's idea of what ssh to use (eg,
+.BR GIT_SSH )
+is relevant.
.TP
-.RI \fB--dget:\fR option |\fB--dput:\fR option |\fB--debsign:\fR option
-Specifies a single additional option to pass to dget, dput or
-debsign. Use repeatedly if multiple additional options are required.
+.RI \fB--dget:\fR option |\fB--dput:\fR option |...
+Specifies a single additional option to pass to
+.BR dget ,
+.BR dput ,
+.BR debsign ,
+.BR dpkg-source ,
+.BR dpkg-buildpackage ,
+.BR dpkg-genchanges ,
+.BR sbuild ,
+.BR ssh ,
+.BR dgit ,
+or
+.BR mergechanges .
+Can be repeated as necessary.
+
+For dpkg-buildpackage, dpkg-genchanges, mergechanges and sbuild,
+this applies only when the program is invoked directly by dgit.
+Usually, for passing options to dpkg-genchanges, you should use
+.BR --ch: \fIoption\fR.
+
+See notes above regarding ssh and dgit.
+
+NB that --gpg:option is not supported (because debsign does not
+have that facility). But see -k.
+.TP
+.BR -d "\fIdistro\fR | " --distro= \fIdistro\fR
+Specifies that the suite to be operated on is part of distro
+.IR distro .
+This overrides the default value found from the git config option
+.BR dgit-suite. \fIsuite\fR .distro .
+The only effect is that other configuration variables (used
+for accessing the archive and dgit-repos) used are
+.BR dgit-distro. \fIdistro\fR .* .
+
+If your suite is part of a distro that dgit already knows about, you
+can use this option to make dgit work even if your dgit doesn't know
+about the suite. For example, specifying
+.B -ddebian
+will work when the suite is an unknown suite in the Debian archive.
+
+To define a new distro it is necessary to define methods and URLs
+for fetching (and, for dgit push, altering) a variety of information both
+in the archive and in dgit-repos. How to do this is not yet
+documented, and currently the arrangements are unpleasant. See
+BUGS.
.TP
.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 it is for the right package and version.
+filename suggests it is for the right package and version - or,
+if there is a _multi.changes file, dgit uses that.
.TP
.BI --existing-package= package
-dgit push needs to canonicalise the suite name. But currently
-there is no way to ask the archive to do this without knowing the
+dgit push needs to canonicalise the suite name. Sometimes, dgit
+lacks a way to ask the archive to do this without knowing the
name of an existing package. Without --new we can just use the
package we are trying to push. But with --new that will not work, so
-we guess that
+we guess
.B dpkg
-exists in the target suite. If it doesn't, you can use this option to
-specify a package which does. If the suite is empty, bad luck.
+or use the value of this option. This option is not needed with the
+default mechanisms for accessing the archive.
+.TP
+.BR -h | --help
+Print a usage summary.
+.TP
+.BI --initiator-tempdir= directory
+dgit rpush uses a temporary directory on the invoking (signing) host.
+This option causes dgit to use
+.I directory
+instead. Furthermore, the specified directory will be emptied,
+removed and recreated before dgit starts, rather than removed
+after dgit finishes. The directory specified must be an absolute
+pathname.
+.SH WORKFLOW - SIMPLE
+It is always possible with dgit to clone or fetch a package, make
+changes in git (using git-commit) on the suite branch
+.RB ( "git checkout dgit/" \fIsuite\fR)
+and then dgit push. You can use whatever gitish techniques you like
+to construct the commit to push; the only requirement is that it is a
+descendant of the state of the archive, as provided by dgit in the
+remote tracking branch
+.BR remotes/dgit/dgit/ \fIsuite\fR.
+
+If you are lucky the other uploaders have also used dgit and
+integrated the other relevant git history; if not you can fetch it
+into your tree and cherry-pick etc. as you wish.
+.SH WORKFLOW - INTEGRATING BETWEEN DGIT AND OTHER GIT HISTORY
+If you are the maintainer of a package dealing with uploads made
+without dgit, you will probably want to merge the synthetic commits
+(made by dgit to represent the uploads) into your git history.
+Normally you can just merge the dgit branch into your own master, or
+indeed if you do your work on the dgit local suite branch
+.BI dgit/ suite
+you can just use dgit pull.
+
+However the first time dgit is used it will generate a new origin
+commit from the archive which won't be linked into the rest of your
+git history. You will need to merge this.
+
+If last upload was in fact made with git, you should usually proceed
+as follows: identify the commit which was actually used to build the
+package. (Hopefully you have a tag for this.) Check out the dgit
+branch
+.RB ( "git checkout dgit/" \fIsuite\fR)
+and merge that other commit
+.RB ( "git merge debian/" \fIversion\fR).
+Hopefully this merge will be trivial because the two trees should
+be the same. The resulting branch head can be merged into your
+working branches
+.RB ( "git checkout master && git merge dgit/" \fIsuite\fR).
+
+If last upload was not made with git, a different approach is required
+to start using dgit. First, do
+.B dgit fetch
+(or clone) to obtain a git history representation of what's in the
+archive and record it in the
+.BI remotes/dgit/dgit/ suite
+tracking branch. Then somehow, using your other git history
+plus appropriate diffs and cherry picks from the dgit remote tracking
+branch, construct a git commit whose tree corresponds to the tree to use for the
+next upload. If that commit-to-be-uploaded is not a descendant of the
+dig remote tracking branch, check it out and say
+.BR "git merge -s ours remotes/dgit/dgit/" \fIsuite\fR;
+that tells git that we are deliberately throwing away any differences
+between what's in the archive and what you intend to upload.
+Then run
+.BR "dgit push"
+to actually upload the result.
+.SH MODEL
+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 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 will also (by default) make signed tags called
+.BI debian/ version
+and push them to dgit-repos, but nothing depends on these tags
+existing.
+
+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 Dgit
+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.
+
+Uploads not made by dgit are represented in git by commits which are
+synthesised by dgit. The tree of each such commit corresponds to the
+unpacked source; there is an origin commit with the contents, and a
+psuedo-merge from last known upload - that is, from the contents of
+the dgit/suite branch.
+
+dgit expects repos that it works with to have a
+.B dgit
+remote. This refers to the well-known dgit-repos location
+(currently, the dgit-repos project on Alioth). dgit fetch updates
+the remote tracking branch for dgit/suite.
+
+dgit does not (currently) represent the orig tarball(s) in git. The
+orig tarballs are downloaded (by dgit clone) into the parent
+directory, as with a traditional (non-gitish) dpkg-source workflow.
+You need to retain these tarballs in the parent directory for dgit
+build and dgit push.
+
+To a user looking at the archive, changes pushed using dgit look like
+changes made in an NMU: in a `3.0 (quilt)' package the delta from the
+previous upload is recorded in a new patch constructed by dpkg-source.
+.SH PACKAGE SOURCE FORMATS
+If you are not the maintainer, you do not need to worry about the
+source format of the package. You can just make changes as you like
+in git. If the package is a `3.0 (quilt)' package, the patch stack
+will usually not be represented in the git history.
+
+If you are the maintainer of a non-native package, you currently have
+two sensible options:
+
+Firstly, you can regard your git history as primary, and the archive
+as an export format. For example, you could maintain topic branches
+in git and a fast-forwarding release branch; or you could do your work
+directly in a merging way on the
+.BI dgit/ suite
+branches. If you do this you should probably use a `1.0' format
+source package if you can. In the archive, the delta between upstream
+will be represented in the single Debian patch.
+
+Secondly, you can use `3.0 (quilt)', and regard your quiltish patch
+stack in the archive as primary. You will have to use other tools
+besides dgit to import and export this patch stack. But see below:
+.SH FORMAT 3.0 (QUILT)
+For a format `3.0 (quilt)' source package, dgit may have to make a
+commit on your current branch to contain metadata used by quilt and
+dpkg-source.
+
+This is because (i) the `3.0 (quilt)' source format cannot represent
+certain trees, and (ii) packing up a tree in `3.0 (quilt)' and then
+unpacking it does not always yield the same tree. Instead,
+dpkg-source insists on the trees having extra quilty metadata and
+patch files in the debian/ and .pc/ directories, which dpkg-source
+sometimes modifies.
+
+dgit will automatically work around this braindamage for you when
+building and pushing. The only thing you need to know is that dgit
+build, sbuild, etc., may make a new commit on your HEAD. If you're
+not a quilt user this commit won't contain any changes to files you
+care about.
+
+You can explicitly request that dgit do just this fixup, by running
+dgit quilt-fixup.
+
+We recommend against the use of `3.0 (quilt)'.
+.SH FILES IN THE SOURCE PACKAGE BUT NOT IN GIT
+This section is mainly of interest to maintainers who want to use dgit
+with their existing git history for the Debian package.
+
+Some developers like to have an extra-clean git tree which lacks files
+which are normally found in source tarballs and therefore in Debian
+source packages. For example, it is conventional to ship ./configure
+in the source tarball, but some people prefer not to have it present
+in the git view of their project.
+
+dgit requires that the source package unpacks to exactly the same
+files as are in the git commit on which dgit push operates. So if you
+just try to dgit push directly from one of these extra-clean git
+branches, it will fail.
+
+As the maintainer you therefore have the following options:
+.TP
+\(bu
+Persuade upstream that the source code in their git history and the
+source they ship as tarballs should be identical. Of course simply
+removing the files from the tarball may make the tarball hard for
+people to use.
+.IP
+One answer is to commit the (maybe autogenerated)
+files, perhaps with some simple automation to deal with conflicts and
+spurious changes. This has the advantage that someone who clones
+the git repository finds the program just as easy to build as someone
+who uses the tarball.
+.TP
+\(bu
+Have separate git branches which do contain the extra files, and after
+regenerating the extra files (whenever you would have to anyway),
+commit the result onto those branches.
+.TP
+\(bu
+Provide source packages which lack the files you don't want
+in git, and arrange for your package build to create them as needed.
+This may mean not using upstream source tarballs and makes the Debian
+source package less useful for people without Debian build
+infrastructure.
+.LP
+Of course it may also be that the differences are due to build system
+bugs, which cause unintended files to end up in the source package.
+dgit will notice this and complain. You may have to fix these bugs
+before you can unify your existing git history with dgit's.

.SH BUGS
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.
-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).
-
-The method of canonicalising suite names is bizarre. See the
-.B --existing-package
-option for one of the implication.s
-
dgit push should perhaps do `git push origin', or something similar,
by default.
+Debian does not have a working rmadison server, so to find out what
+version of a package is in the archive, or to canonicalise suite
+names, we ssh directly into the ftpmaster server and run psql there to
+access the database.
+
The mechanism for checking for and creating per-package repos on
alioth is a hideous bodge. One consequence is that dgit currently
only works for people with push access.
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.
+dgit's build functions, and dgit push, should not make any changes to
+your current HEAD. Sadly this is necessary for packages in the `3.0
+(quilt)' source format. This is ultimately due to design problems in
+quilt and dpkg-source.
+
+There should be an option which arranges for the `3.0 (quilt)'
+autocommit to not appear on your HEAD, but instead only in the
+remote tracking suite branch.
The option parser requires values to be cuddled to the option name.
-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. I'm assured that the archive layout is a
-`well known algorithm' by now.
+dgit assumes knowledge of the archive database. (The information dgit
+needs is not currently available via any public online service with a
+well-defined interface, let alone a secure one.)
---dry-run often does not work with fetch, even though this is a
-logically plausible request. (It fails, instead.)
+--dry-run does not always work properly, as not doing some of the git
+fetches may result in subsequent actions being different. Doing a
+non-dry-run dgit fetch first will help.
