- dgit clone package [suite] [./dir|/dir]
Consults the archive and dgit-repos to construct the git view of history for package in suite (sid by default) in a new directory (named ./package by default); also, downloads any necessary orig tarballs.
The suite's git tip is left on the local branch dgit/suite ready for work, and on the corresponding dgit remote tracking branch. The origin remote will be set up to point to the package's dgit-repos tree for the distro to which suite belongs.
suite may be a combination of several underlying suites in the form mainsuite,subsuite...; see COMBINED SUITES in dgit(7).
For your convenience, the vcs-git remote will be set up from the package's Vcs-Git field, if there is one - but note that in the general case the history found there may be different to or even disjoint from dgit's view.
- dgit fetch [suite]
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 remotes/dgit/dgit/suite. If the current branch is dgit/suite then dgit fetch defaults to suite; otherwise it parses debian/changelog and uses the suite specified there. suite may be a combined suite, as for clone.
- dgit pull [suite]
Does dgit fetch, and then merges the new head of the remote tracking branch remotes/dgit/dgit/suite into the current branch.
- dgit build ...
Runs dpkg-buildpackage with some suitable options. Options and arguments 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.
- dgit build-source ...
Builds the source package, and a changes file for a prospective source-only upload, using dpkg-source. The output is left in package_version.dsc and package_version_source.changes.
Tagging, signing and actually uploading should be left to dgit push.
- dgit clean
Cleans the current working tree (according to the --clean= option in force).
- dgit help
Print a usage summary.
- dgit sbuild ...
Constructs the source package, uses sbuild to do a binary build, and uses mergechanges to merge the source and binary changes files. Options and arguments after sbuild will be passed on to sbuild. The output is left in package_version_multi.changes.
Tagging, signing and actually uploading should be left to dgit push.
- dgit gbp-build ...
Runs git-buildpackage with some suitable options. Options and arguments after gbp-build will be passed on to git-buildpackage.
By default this uses --quilt=gbp, so HEAD should be a git-buildpackage style branch, not a patches-applied branch.
Tagging, signing and actually uploading should be left to dgit push.
- dgit push [suite]
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. It is normally best to do the build with dgit too (eg with dgit sbuild): some existing build tools pass unhelpful options to dpkg-source et al by default, which can result in the built source package not being identical to the git tree.
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, adjusts the .changes to include any .origs which the archive lacks and exclude .origs which the archive has (so -sa and -sd are not needed when building for dgit push), 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.
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.
If dgit push fails while uploading, it is fine to simply retry the dput on the .changes file at your leisure.
- dgit rpush build-host:build-dir [push args...]
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:
1. Clone on build host (dgit clone) 2. Edit code on build host (edit, git commit) 3. Build package on build host (dgit build) 4. Test package on build host or elsewhere (dpkg -i, test) 5. Upload by invoking dgit rpush on host with your GPG key.
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.
The remaining arguments are treated just as dgit push would handle them.
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 one in [ ], to support IPv6 address literals).
You will need similar enough versions of dgit on the build-host and the invocation host. The build-host needs gnupg installed, with your public key in its keyring (but not your private key, obviously).
- dgit setup-new-tree
Configure the current working tree the way that dgit clone would have set it up. Like running dgit setup-useremail and setup-mergechangelogs (but only does each thing if dgit is configured to do it automatically). You can use these in any git repository, not just ones used with the other dgit operations.
- dgit setup-useremail
Set the working tree's user.name and user.email from the distro-specific dgit configuration (dgit-distro.distro.user-name and .user-email), or DEBFULLNAME or DEBEMAIL.
- dgit setup-mergechangelogs
Configures a git merge helper for the file debian/changelog which uses dpkg-mergechangelogs.
- dgit quilt-fixup
`3.0 (quilt)' format source packages need changes representing not only in-tree but also as patches in debian/patches. dgit quilt-fixup checks whether this has been done; if not, dgit will make appropriate patches in debian/patches and also commit the resulting changes to git.
This is normally done automatically by dgit build and dgit push.
dgit will try to turn each relevant commit in your git history into a new quilt patch. dgit cannot convert nontrivial merges, or certain other kinds of more exotic history. If dgit can't find a suitable linearisation of your history, by default it will fail, but you can ask it to generate a single squashed patch instead.
- dgit import-dsc [sub-options] ../path/to/.dsc [+|..]branch
Import a Debian-format source package, specified by its .dsc, into git, the way dgit fetch would do.
This does about half the work of dgit fetch: it will convert the .dsc into a new, orphan git branch. Since dgit has no access to a corresponding source package archive or knowledge of the history it does not consider whether this version is newer than any previous import or corresponding git branches; and it therefore does not make a pseudomerge to bind the import into any existing git history.
There is only only sub-option:
--require-valid-signature causes dgit to insist that the signature on the .dsc is valid (using the same criteria as dpkg-source -x). Otherwise, dgit tries to verify the signature but the outcome is reported only as messages to stderr.
If branch is prefixed with + then if it already exists, it will be simply ovewritten, no matter its existing contents. If branch is prefixed with .. then if it already exists and dgit actually imports the dsc (rather than simply reading the git commit out of the Dgit field), dgit will make a pseudomerge so that the result is necessarily fast forward from the existing branch. Otherwise, if branch already exists, dgit will stop with an error message.
If branch does not start with refs/, refs/heads/ is prepended. The specified branch is unconditionally updated.
If the specified .dsc contains a Dgit field, dgit will simply make a branch of that commit. If you cannot manage to find that commit anywhere, consider --force-import-dsc-with-dgit-field.
- dgit version
Prints version information and exits.
- dgit clone-dgit-repos-server destdir
Tries to fetch a copy of the source code for the dgit-repos-server, as actually being used on the dgit git server, as a git tree.
- --dry-run | -n
Go through the motions, fetching all information needed, but do not 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.
- --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.
Use keyid for signing the tag and the upload. The default comes from the distro's keyid config setting (see Configuration, below), or failing that, the uploader trailer line in debian/changelog.
does not sign tags or uploads (meaningful only with push).
Specifies that we should process source package package rather than looking in debian/control or debian/changelog. Valid with dgit fetch and dgit pull, only.
- --clean=git | -wg
Use git clean -xdf to clean the working tree, rather than running the package's rules clean target.
This will delete all files which are not tracked by git. (Including any files you forgot to git add.)
--clean=... options other than dpkg-source are useful when the package's clean target is troublesome, or to avoid needing the build-dependencies.
- --clean=git-ff | -wgf
Use git clean -xdff to clean the working tree. Like git clean -xdf but it also removes any subdirectories containing different git trees (which only unusual packages are likely to create).
- --clean=check | -wc
Merely check that the tree is clean (does not contain uncommitted files). Avoids running rules clean, and can avoid needing the build-dependencies.
- --clean=none | -wn
Do not clean the tree, nor check that it is clean. Avoids running rules clean, and can avoid needing the build-dependencies. If there are files which are not in git, or if the build creates such files, a subsequent dgit push will fail.
- --clean=dpkg-source | -wd
Use dpkg-buildpackage to do the clean, so that the source package is cleaned by dpkg-source running the package's clean target. This is the default. Requires the package's build dependencies.
- --clean=dpkg-source-d | -wdd
Use dpkg-buildpackage -d to do the clean, so that the source package is cleaned by dpkg-source running the package's clean target. The build-dependencies are not checked (due to -d), which violates policy, but may work in practice.
- -N | --new
The package is or may be new in this suite. Without this, dgit will refuse to push. It may (for Debian, will) be unable to access the git history for any packages which have been newly pushed and have not yet been published.
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.)
Declare that even though your git branch is not a descendant of the version in the archive according to the revision history, it really does contain all the (wanted) changes from that version.
This option is useful if you are the maintainer, and you have incorporated NMU changes into your own git workflow in a way that doesn't make your branch a fast forward from the NMU.
previous-version ought to be the version currently in the archive. If previous-version is not specified, dgit will check that the version in the archive is mentioned in your debian/changelog. (This will avoid losing changes unless someone committed to git a finalised changelog entry, and then made later changes to that version.)
dgit push --overwrite will make a pseudo-merge (that is, something that looks like the result of git merge -s ours) to stitch the archive's version into your own git history, so that your push is a fast forward from the archive.
(In quilt mode gbp, dpm or unpatched, implying a split between the dgit view and the maintainer view, the pseudo-merge will appear only in the dgit view.)
Upload to a DELAYED queue.
WARNING: If the maintainer responds by cancelling your upload from the queue, and does not make an upload of their own, this will not rewind the git branch on the dgit git server. Other dgit users will then see your push (with a warning message from dgit) even though the maintainer wanted to abolish it. Such users might unwittingly reintroduce your changes.
If this situation arises, someone should make a suitable dgit push to update the contents of dgit-repos to a version without the controversial changes.
Specifies that when a split view quilt mode is in operation, and dgit calculates (or looks up in its cache) a dgit view corresponding to your HEAD, the dgit view will be left in ref. The specified ref is unconditionally overwritten, so don't specify a branch you want to keep.
This option is effective only with the following operations: quilt-fixup; push; all builds. And it is only effective with --[quilt=]gbp, --[quilt=]dpm, --quilt=unpatched.
If ref does not start with refs/ it is taken to to be a branch - i.e. refs/heads/ is prepended.
Declare that you are deliberately doing something. This can be used to override safety catches, including safety catches which relate to distro-specific policies. The use of --deliberately is declared and published in the signed tags generated for you by dgit, so that the archive software can give effect to your intent, and for the benefit humans looking at the history. The meanings of somethings understood in the context of Debian are discussed below:
Declare that you are deliberately rewinding history. When pushing to Debian, use this when you are making a renewed upload of an entirely new source package whose previous version was not accepted for release from NEW because of problems with copyright or redistributibility.
Declare that you are deliberately including, in the git history of your current push, history which contains a previously-submitted version of this package which was not approved (or has not yet been approved) by the ftpmasters. When pushing to Debian, only use this option after verifying that: none of the rejected-from-NEW (or never-accepted) versions in the git history of your current push, were rejected by ftpmaster for copyright or redistributability reasons.
Declare that you are deliberately rewinding history and want to throw away the existing repo. Not relevant when pushing to Debian, as the Debian server will do this automatically when necessary.
When fixing up source format `3.0 (quilt)' metadata, insist on generating a linear patch stack: one new patch for each relevant commit. If such a stack cannot be generated, fail. This is the default for Debian.
HEAD should be a series of plain commits (not touching debian/patches/), and pseudomerges, with as ancestor a patches-applied branch.
When fixing up source format `3.0 (quilt)' metadata, prefer to generate a linear patch stack (as with --quilt=auto) but if that doesn't seem possible, try to generate a single squashed patch for all the changes made in git (as with --quilt=smash). This is not a good idea for an NMU in Debian.
When fixing up source format `3.0 (quilt)' metadata, generate a single additional patch for all the changes made in git. This is not a good idea for an NMU in Debian.
(If HEAD has any in-tree patches already, they must apply cleanly. This will be the case for any trees produced by dgit fetch or clone; if you do not change the upstream version nor make changes in debian/patches, it will remain true.)
Check whether source format `3.0 (quilt)' metadata would need fixing up, but, if it does, fail. You must then fix the metadata yourself somehow before pushing. (NB that dpkg-source --commit will not work because the dgit git tree does not have a .pc directory.)
- --quilt=nocheck | --no-quilt-fixup
Do not check whether up source format `3.0 (quilt)' metadata needs fixing up. If you use this option and the metadata did in fact need fixing up, dgit push will fail.
- --[quilt=]gbp | --[quilt=]dpm | --quilt=unapplied
Tell dgit that you are using a nearly-dgit-compatible git branch, aka a maintainer view, and do not want your branch changed by dgit.
--gbp (short for --quilt=gbp) is for use with git-buildpackage. Your HEAD is expected to be a patches-unapplied git branch, except that it might contain changes to upstream .gitignore files. This is the default for dgit gbp-build.
--dpm (short for --quilt=dpm) is for use with git-dpm. Your HEAD is expected to be a patches-applied git branch, except that it might contain changes to upstream .gitignore files.
--quilt=unapplied specifies that your HEAD is a patches-unapplied git branch (and that any changes to upstream .gitignore files are represented as patches in debian/patches).
With --quilt=gbp|dpm|unapplied, dgit push (or precursors like quilt-fixup and build) will automatically generate a conversion of your git branch into the right form. dgit push will push the dgit-compatible form (the dgit view) to the dgit git server. The dgit view will be visible to you in the dgit remote tracking branches, but your own branch will not be modified. dgit push will create a tag debian/version for the maintainer view, and the dgit tag archive/debian/version for the dgit view. dgit quilt-fixup will merely do some checks, and cache the maintainer view.
If you have a branch like this it is essential to specify the appropriate --quilt= option! This is because it is not always possible to tell: a patches-unapplied git branch of a package with one patch, for example, looks very like a patches-applied branch where the user has used git revert to undo the patch, expecting to actually revert it. However, if you fail to specify the right --quilt option, and you aren't too lucky, dgit will notice the problem and stop, with a useful hint.
- -ddistro | --distro=distro
Specifies that the suite to be operated on is part of distro distro. This overrides the default value found from the git config option dgit-suite.suite.distro. The only effect is that other configuration variables (used for accessing the archive and dgit-repos) used are dgit-distro.distro.*.
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 -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 set this up is not yet documented.
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.
If the specified changesfile pathname contains slashes, the directory part is also used as the value for --build-products-dir; otherwise, the changes file is expected in that directory (by default, in ..).
When doing a build, delete any changes files matching package_version_*.changes before starting. This ensures that dgit push (and dgit sbuild) will be able to unambigously identify the relevant changes files from the most recent build, even if there have been previous builds with different tools or options. The default is not to remove, but --no-rm-old-changes can be used to override a previous --rm-old-changes or the .rm-old-changes configuration setting.
Specifies where to find the built files to be uploaded. By default, dgit looks in the parent directory (..).
Do not delete the destination directory if clone fails.
Generates a DEP-14 tag (eg debian/version) as well as a dgit tag (eg archive/debian/version) where possible. This is the default.
Do not generate a DEP-14 tag, except in split quilt view mode. (On servers where only the old tag format is supported, the dgit tag will have the DEP-14 name. This option does not prevent that.)
Insist on generating a DEP-14 tag as well as a dgit tag. If the server does not support that, dgit push will fail.
Prints debugging information to stderr. Repeating the option produces more output (currently, up to -DDDD is meaningfully different).
Specifies a git configuration option, to be used for this run. dgit itself is also controlled by git configuration options.
- -vversion|_ | --since-version=version|_
Specifies the -vversion 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 _ 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).
Passed to dpkg-genchanges (eventually).
Specifies a single additional option to pass, eventually, to dpkg-genchanges.
Options which are safe to pass include -C (and also -si -sa -sd although these should never be necessary with Debian since dgit automatically calculates whether .origs need to be uploaded.)
For other options the caveat below applies.
- --curl:option | --dput:option |...
Specifies a single additional option to pass to curl, dput, debsign, dpkg-source, dpkg-buildpackage, dpkg-genchanges, sbuild, ssh, dgit, apt-get, apt-cache, gbp-pq, gbp-build, or mergechanges. Can be repeated as necessary.
Use of this ability should not normally be necessary. It is provided for working around bugs, or other unusual situations. If you use these options, you may violate dgit's assumptions about the behaviour of its subprograms and cause lossage.
For dpkg-buildpackage, dpkg-genchanges, mergechanges and sbuild, the option applies only when the program is invoked directly by dgit. Usually, for passing options to dpkg-genchanges, you should use --ch:option.
Specifying --git is not effective for some lower-level read-only git operations performed by dgit, and also not when git is invoked by another program run by dgit.
See notes below regarding ssh and dgit.
NB that --gpg:option is not supported (because debsign does not have that facility). But see -k and the keyid distro config setting.
- --curl=program | --dput=program |...
Specifies alternative programs to use instead of curl, dput, debsign, dpkg-source, dpkg-buildpackage, dpkg-genchanges, sbuild, gpg, ssh, dgit, apt-get, apt-cache, git, gbp-pq, gbp-build, or 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, and is not affected by --dgit=).
gbp-build's value is used instead of gbp build or git-buildpackage. (The default is the latter unless the former exists on PATH.) gbp-pq's value is used instead of gbp pq. In both cases, unusually, the specified value is split on whitespace to produce a command and possibly some options and/or arguments.
For ssh, the default value is taken from the DGIT_SSH or 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 dgit-distro.distro.ssh and .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, GIT_SSH) is relevant.
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 dpkg or use the value of this option. This option is not needed with the default mechanisms for accessing the archive.
Print a usage summary.
dgit rpush uses a temporary directory on the invoking (signing) host. This option causes dgit to use 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.
Instructs dgit to try to proceed despite detecting what it thinks is going to be a fatal problem. This is probably not going to work. These options are provided as an escape hatch, in case dgit is confused. (They might also be useful for testing error cases.)
Tell dgit import-dsc to treat a .dsc with a Dgit field like one without it. The result is a fresh import, discarding the git history that the person who pushed that .dsc was working with.
Carry on even if dgit thinks that your git tree contains changes (relative to your .orig tarballs) which dpkg-source is not able to represent. Your build or push will probably fail later.
Use the set of .origs specified in your .changes, exactly, without regard to what is in the archive already. The archive may well reject your upload.
Carry on despite dgit not understanding your source package format. dgit will probably mishandle it.
Do not check whether .dsc and .changes match. The archive will probably reject your upload.
- --force-import-gitapply-absurd | --force-import-gitapply-no-absurd
Force on or off the use of the absurd git-apply emulation when running gbp pq import when importing a package from a .dsc. See Debian bug #841867.
dgit can be configured via the git config system. You may set keys with git-config (either in system-global or per-tree configuration), or provide -ckey=value on the dgit command line.
Settings likely to be useful for an end user include:
- dgit-suite.suite.distro distro
Specifies the distro for a suite. dgit keys off the suite name (which appears in changelogs etc.), and uses that to determine the distro which is involved. The config used is thereafter that for the distro.
suite may be a glob pattern.
- dgit.default.distro distro
The default distro for an unknown suite.
for each dgit-distro.distro.*, the default value used if there is no distro-specific setting.
One of the values for the command line --clean= option; used if --clean is not specified.
One of the values for the command line --quilt= option; used if --quilt is not specified.
Boolean, used if neither --rm-old-changes nor --no-rm-old-changes is specified. The default is not to remove.
- dgit-distro.distro.readonly auto|a | true|t|y|1 | false|f|n|0
Whether you have push access to the distro. For Debian, it is OK to use auto, which uses readonly mode if you are not pushing right now; but, setting this to false will avoid relying on the mirror of the dgit git repository server.
See also -k.
- dgit-distro.distro.mirror url
Not relevant for Debian.
Might be useful if you have an intermediate queue server.
- dgit-distro.distro.user-name dgit-distro.distro.user-email
Values to configure for user.name and user.email in new git trees. If not specified, the DEBFULLNAME and DEBEMAIL environment variables are used, respectively. Only used if .setup-usermail is not disabled.
Whether to set user.name and user.email in new git trees. True by default. Ignored for dgit setup-setup-useremail, which does it anyway.
Whether to setup a merge driver which uses dpkg-mergechangelogs for debian/changelog. True by default. Ignored for dgit setup-mergechangelogs, which does it anyway.
Program to use instead of cmd. Works like --cmd=... .
Extra options to pass to cmd. Works like --cmd:... . To pass several options, configure multiple values in git config (with git config --add). The options for dgit.default.opts-cmd dgit-distro.distro/push.opts-cmd and are all used, followed by options from dgit's command line.
There are many other settings which specify how a particular distro's services (archive and git) are provided. These should not normally be adjusted, but are documented for the benefit of distros who wish to adopt dgit.
If set, overrides corresponding non /push config when readonly=false, or when pushing and readonly=auto.
dgit-distro.distro.archive-query ftpmasterapi: | madison:distro | dummycat:/path | sshpsql:user@host:dbname
- DGIT_SSH, GIT_SSH
specify an alternative default program (and perhaps arguments) to use instead of ssh. DGIT_SSH is consulted first and may contain arguments; if it contains any whitespace will be passed to the shell. GIT_SSH specifies just the program; no arguments can be specified, so dgit interprets it the same way as git does. See also the --ssh= and --ssh: options.
- DEBEMAIL, DEBFULLNAME
Default git user.email and user.name for new trees. See dgit setup-new-tree.
- gpg, dpkg-..., debsign, git, curl, dput, LWP::UserAgent
and other subprograms and modules used by dgit are affected by various environment variables. Consult the documentaton for those programs for details.
There should be a `dgit rebase-prep' command or some such to turn a fast-forwarding branch containing pseudo-merges back into a rebasing patch stack. It might have to leave a note for a future dgit push.
If the dgit push fails halfway through, it is not necessarily restartable and idempotent. It would be good to check that the proposed signing key is available before starting work.
dgit's build functions, and dgit push, may make changes to your current HEAD. Sadly this is necessary for packages in the `3.0 (quilt)' source format. This is ultimately due to what I consider design problems in quilt and dpkg-source.
--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. --damp-run is likely to work much better.
