[dgit.git] / debian / changelog

dgit (2.17~) unstable; urgency=medium

  dgit-badcommit-fixup: 
  * Do not investigate symrefs.  Closes:#850547.

  Test suite:
  * Internal improvements.
  * badcommit-rewrite: Fix operation using installed version of fixup.
  * Arrange to pass --debug-quick-random to gpg-agent.
  * Strip block count out of find -ls output - it is unstable!

 --

dgit (2.16.2) unstable; urgency=low

  dgit-badcommit-fixup: 
  * Fix crash when running for 2nd time in bare repo.
  * In --check mode, exit with status 2 if things are not fine.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sat, 07 Jan 2017 13:31:50 +0000

dgit (2.16.1) UNRELEASED; urgency=low

  * dgit-badcommit-fixup: New mode --check which is readonly.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sat, 07 Jan 2017 13:04:49 +0000

dgit (2.16) unstable; urgency=low

  Dealing with fallout from #849041:
  * Provide dgit-badcommit-fixup history-rewriting script.
  * New rewrite map feature, which allows dgit git server to adjust
    clients' interpretation of Dgit fields, so that history-rewriting is
    effective.  (Feature is only partially implemented right now -
    enough to dig current Debian users out of the hole.)  Re:#850431.

  Test suite:
  * New test case for history-rewriting.
  * Change `local foo=$(bar)' idiom to `local foo; foo=$(bar)' since
    the former does not trip set -e even if bar fails :-(. 

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Fri, 06 Jan 2017 20:46:30 +0000

dgit (2.15) UNRELEASED; urgency=high

  Infastructure:
  * Prevent introduction of new commits which lack `committer'
    information.  Ie, prevent the reception of new commits afflicted by
    #849041.  Existing commits are tolerated.

  Test suite:
  * Be much stricter about messages from git-fsck.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 05 Jan 2017 18:20:23 +0000

dgit (2.14) unstable; urgency=critical

  CRITICAL BUGFIX:
  * Do not generate bogus commits with --overwrite or import-dsc.
    Closes:#849041.

  Test suite:
  * Run a lot of git-fsck.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Wed, 04 Jan 2017 22:52:55 +0000

dgit (2.13) unstable; urgency=high

  Changed behaviour:
  * quilt fixup: Permit creation of patches which delete files, by psssing
    --include-removal to dpkg-source, and tolerating it when we do our
    quilt fixup analysis.  dpkg-source has supported this since at least
    stretch.  Closes:#848901.

  Error messages:
  * Improve "cannot represent change" message: print the git old and new
    modes too.

  Bugfix:
  * Import: Switch back to unpa branch on patch import iterations.
    In particular, do not fail utterly if dpkg-source and gbp disagree.
    Closes:#848843.

  Documentation [Sean Whitton]:
  * dgit-maint-gbp(7): Remove reference to closed bug.  Closes:#848725.
  * dgit-sponsorship(7): Update in light of fixed #844129.  Closes:#848789.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Wed, 21 Dec 2016 01:32:41 +0000

dgit (2.12) unstable; urgency=high

  Changed behaviours:
  * By default, generate a DEP-14 tag as well as a dgit archive/*
    tag, even in non-split-view quilt modes.  Closes:#844129.
  * Version tags mangling: Protect dots, as per proposed update to DEP-14.

  Documentation:
  * dgit-maint-merge(7): Explain how to change to this workflow
    from an existing git workflow.  [Sean Whitton]  Closes:#847807.
  * dgit-maint-native(7): Clarify that we mean native source format.
    [Phil Hands]  Closes:#847987.

  Error messages:
  * Slightly better message when .dsc not found.  Apropos of #844128.
  * Give better advice if .dsc/.changes signing fails: if no changes
    are needed to the package, user may indeed just debsign and dput.
    Closes:#844131.
  * Produce better error reporting when absurd git wrapper fails
    on a patch during .dsc import.  Apropos of #848391.

  Bugfixes:
  * If we cannot hardlink origs into our extraction area, use symlinks
    instead.  Closes:#844570.
  * Suppress some leftover debugging output from import-dsc.
    Closes:#847658.
  * Do not fail when cloning a package containing dangling symlinks.
    Closes:#848512.
  * Do not fail to import a .dsc containing patches which patch files
    multiple times, due to #848611.  Closes:#848391.
  * Do not fail to import a .dsc containing patches to .git/ (!)
  * infra: dgit-repos-policy-debian which broke due to recent git setting
    GIT_ALTERNATE_OBJECT_DIRECTORIES in the pre-receive-hook.
    (fixes test suite regression in stretch).

  Test suite:
  * Provide and use stunt lintian and debuild, to avoid lintian
    complaining about our stupid test packages.
    (fixes test suite regression in stretch).

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 19 Dec 2016 17:35:18 +0000

dgit (2.11) unstable; urgency=medium

  Documentation:
  * dgit-user(7): Better explanation of combined suites (comma syntax).
    Thanks to Sean Whitton for review and suggestions.
  * dgit(1), dgit(7): Better reference docs for combined suites.
  * dgit(1): Improve formatting of rpush section.

  Test suite:
  * Replace make in Test-Depends with build-essential.  Most of the tests
    do in fact run dpkg-buildpackage which bombs out if build-essential is
    missing.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 08 Nov 2016 22:41:29 +0000

dgit (2.10) unstable; urgency=medium

  New features:
  * Support the Debian *-security suites.
  * New comma-separated multiple-suite merging facility (readonly),
    so that users can easily track "jessie, or jessie-security".
  * dgit-user(7): Suggest `dgit clone P jessie,-security'.

  Bugfixes:
  * Cope when an orig tarball is a tarbomb.  Ie, if it contains
    other than one single directory toplevel.  Closes:#843422.
  * Actually honour the branch name, if we are on dgit branch, to specify
    the suite, as documented in the manpage.
  * When cloning a distro which has no git server, correctly leave
    the user on the local dgit branch, not on `master'.
  * Fix an unconditional print that was supposed to be a printdebug:
      origs <blah>.orig.tar.gz f.same=1 #f._differ=-1
  * Print a slightly better message if .git found in orig tarball(s).

  Test suite:
  * Test suite: Add fakeroot and make to Test-Depends.  These aren't
    necessarily pulled in by anything else.  (dpkg-dev Recommends
    build-essential.  But we don't actually need build-essential.)

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 08 Nov 2016 01:08:51 +0000

dgit (2.9) unstable; urgency=medium

  New features:
  * During push, automatically calculate which .origs are required,
    so user never needs [--ch:]-sa or [--ch:]-sd.  Closes:#829116.
  * New import-dsc feature.
  * New option --dgit-view-save= for split view quilt modes.
    In particular, means that the output of a split view quilt-fixup
    is left somewhere useful.
  * dgit clone: Set timestamps in cloned tree to a single unified time.
    This makes it less likely that the user will trip over any
    timestamp-dependent FTBFS bugs (eg #842452).
  * Support dgit --delayed= push (with a warning in the manpage
    about possible skew).
  * dgit gbp-build will arrange to let gbp buildpackage generate
    .orig tarballs if it seems applicable.  Closes:#841094.

  Documentation improvements:
  * dgit-*(7).  Many new tutorial manpages, several written and many
    improved by Sean Whitton.
  * dgit(7): Substantial updates, including documenting split view.
  * dgit(1): Better cross-references.
  * dgit(1): Remove obsolete workflow information.
  * dgit(1): Improved BUGS section.
  * Fix changelog entry for SIGPIPE to correctly mention
    Closes:#841090.

  Bugfixes:
  * Split brain mode: Fix --new.  Closes:#842577.
  * Properly look for .origs etc. in .., fetching them less often.
    Closes:#842386.
  * Reject `dgit pull' in split view quilt modes, to avoid
    creating unfortunate wreckage on non-dgit-view branches.
    Closes:#842608.
  * Cope when cloning suite which doesn't receive uploads,
    like testing.  Closes:#842621.
  * Properly fetch all archive dgit view tags, as we intended.
  * Actually provide a -p (--package=) option (!)

  Test suite fixes:
  * Test suite: Explicitly configure user.name and user.email, so
    that tests work when environment doesn't have defaults.
    Closes:#842279 (I hope).

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 31 Oct 2016 12:47:18 +0000

dgit (2.8) unstable; urgency=medium

  * When in split build mode for `gbp-build' or `build', run
    mergechanges as is required.  Closes:#841990.
  * Test suite: build-mode-*: Check that right .changes comes out
    (detects #841990).
  * Defend against debian/patches/series being an unusual object, in case
    dpkg-source doesn't, in absurd git-apply fallback.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 25 Oct 2016 17:29:23 +0100

dgit (2.7) unstable; urgency=medium

  Absurd bugfix for serious bug:
  * Work around `git-apply' problems (eg #841865, #829067) exposed by
    `gbp pq import' (#841866) by sometimes falling back to an emulation of
    git-apply in terms of dpkg-source --before-build.  Closes:#841867.

  Minor changes:
  * dgit(1): Reorder the options, moving more important ones earlier.
  * dgit(1): Some more info about --deliberately.
  * Provide various --force-something options.  Please don't use them.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 24 Oct 2016 02:37:28 +0100

dgit (2.6) unstable; urgency=medium

  Fixes to HTTP handling:
  * Check for non-2xx HTTP status codes from ftpmaster api server.
  * Always honour --curl= and --curl:.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 23 Oct 2016 14:57:22 +0100

dgit (2.5) unstable; urgency=low

  Substantive changes:
  * Do not crash in split brain quilt modes when the two brains are
    actually identical.  (Eg --quilt=gbp with no patches.)  Closes:#841770.
  * Switch to new archive/ tag format by default, even in
    non-split-brain mode.
  * Provide --gbp and --dpm as aliases for --quilt=gbp and --quilt=dpm.

  Documentation:
  * dgit-maint-merge(7): New tutorial manpage from Sean Whitton.

  Test suite:
  * Introduce setup/gnupg, to help work around gnupg2 bug #841143
    and improve performance by amortising gnupg migration cost.
  * Various bugfixes.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 23 Oct 2016 13:20:23 +0100

dgit (2.4) unstable; urgency=low

  Bugfixes:
  * split brain cache: Fix a wrong implicit reference to $_.
    Closes:#841383.
  * split brain cache: Make sure to write reflog entries for cache updates
    even if the eventual tree (and therefore commit) is the same.
    Otherwise, after updating dgit, the cache might have the right answer
    but not be refreshed even by a build.
  * dgit gbp-build: No longer invent a --git-debian-branch option.
    Usually the user is a maintainer using split brain, and we should rely
    on their own gbp configuration to specify the right check.
    Closes:#841100.

  Minor docs fix:
  * dgit(1): Document which --ch: options are a good idea.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 20 Oct 2016 16:31:54 +0100

dgit (2.3) unstable; urgency=low

  * With --overwrite, do not check all sorts of tags (which may
    not exist, or might contain wrong things).  Closes:#841101.
  * When generating pseudomerge in quilt split brain mode due to
    --overwrite, actually include the version number in the commit
    message.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 18 Oct 2016 01:58:05 +0100

dgit (2.2) unstable; urgency=low

  * Fix config relating to Debian to actually make split brain mode
    work.  Closes:#841085.
  * Detect SIGPIPE (and SIGCHLD) being blocked or ignored.
    Closes:#841090.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 17 Oct 2016 17:31:18 +0100

dgit (2.1) unstable; urgency=low

  * Do not crash due in clone to failure to handle dpkg-parsechangelog
    SIGPIPE.  Closes:#840989.  Avoids:
       dgit: failed command: dpkg-parsechangelog --format rfc822 --all
       dgit: subprocess died due to fatal signal PIPE
  * git- prefixes: Fix some occurrences of `git-foo' in infrastructure,
    messages, and test suite.  Filter out .../git-core from PATH in
    test suite so that we catch future occurrences.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 16 Oct 2016 19:05:14 +0100

dgit (2.0) unstable; urgency=low

  Incompatible change:
  * dgit sbuild: does not pass -A to sbuild.  Consequently the default
    build is now simply sbuild's default.  With older sbuilds it was
    possible to override dgit's -A by passing another option.  But this
    has been changed recently and now this default setting is very awkward
    to change for the dgit user.
  * dgit gbp-build: Make --quilt=gbp the default.  (See below.)
  * New tag format (for dgit view) archive/debian/VERSION.

  Major new feature:
  * --quilt=gbp, --quilt=dpm, --quilt=unpacked: Introduce facility for
    split view (dgit/mainiainer view), to improve compatibility with some
    workflow tools.

  New checks and improved behaviours in dgit:
  * When running dpkg-buildpackage, cope if user specified -g or -G.
  * dgit sbuild: check that the set of .changes files found is as we
    expect, before calling mergechanges.  Re:#800060.
  * dgit sbuild: Rename the used-up .changes files to `.inmulti' to
    avoid accidental use of the wrong one (by software, or by users).
  * dgit sbuild: Check that the binary .changes file doesn't contain a
    .dsc.
  * Introduce --rm-old-changes to delete previous builds' changes files.
  * Remove any pre-existing _source.changes file before building source,
    as a safety check.
  * No longer tolerate a multitude of .changes files when doing push.
    Instead, insist on a single one.  Closes:#800110.
  * dgit sbuild no longer deletes extranious .changes files; instead
    we rely on --rm-old-changes, or failing that, fail early.
  * When doing quilt linearisation, treat upstream .gitignores not
    in the toplevel the same way we treat ones in the toplevel.
  * When automatically generating quilt patch, honour GIT_COMMITTER_DATE
    for filename creation (makes filename deterministic in test suite).
  * New --overwrite option, replaces need to for user to use
    git merge -s ours.  Closes:#838718.
  * When generating quilt patches from git commits, make patches that
    look quite like git-format-patch output (rather than strange things
    based on an obselete interpretation of DEP-3).
  * When generating quilt patches from git commits, honour (and strip)
    any Gbp-Pq headers (that we understand).
  * Several dgit-generated commits now have slightly better annotations
    from dgit about what it was doing.
  * Before committing to push, check that .dsc and .changes correspond.
    Closes:#800060.
  * Better error message if non-split-brain patch stack no longer
    applies (due to new upstream version, or user messing with it).
    Closes:#833025.
  * Better error message if HEAD contains changes unrepresentable
    by `3.0 (quilt)'.  Closes:#834618.
  * Much better error message when HEAD and .dsc do not match.
    Closes:#809516.

  Infrastructure:
  * dgit-repos-policy-debian: Better error handling.
  * dgit-repos-policy-debian.: fix git-cat-file-handling with multiple
    taints in db (!).
  * dgit-infrastructure has, and uses, its own copies of the perl modules.
    This avoids introducing a versioned dependency between dgit and
    dgit-infrastructure (and also makes it easier to test cross-version
    compatibility).

  Documentation:
  * Document the dgit-distro.DISTRO.quilt-mode config setting.
  * Clarify the --clean= options' documentation.  Closes:#800054.
  * Discourage use of the --PROGRAM:OPTION escape hatch.  (Apropos
    of various bug reports including #800060 and #833025.)
  * Document the expected form of HEAD for each --quilt= mode.

  Bugfixes:
  * When cleaning up after failed clone, stat the to-be-cleaned-up
    directory before running rmtree on it.  Closes:#796773.
  * Do not call "warn" on failure of cleanup handler in END block
    (since warn has been made fatal and aborts the cleanup chain).
  * Print better error message (with `fail' rather than `die') if
    `dgit clone' cannot create the destination directory.
  * Properly substitute $changesfile in one of the `You can retry'
    messages.  Closes:#800078.
  * Pass --ch:* and -v options to dpkg-buildpackage when building
    source.  Fixes bad Perl poetry syntax.  Closes:#829121.
  * When synthesing a commit from a .dsc from the archive, stop
    internal git reset from printing a confusing message about HEAD.
  * Turn off git gc in the private working areas.
  * Do not fail to do some important quilt processing in some
    --quilt modes.
  * Fix two calls to chdir without proper error checking.
  * Fix a couple of bugs in error reporting.
  * Fix several bugs in .orig detection/recognition.
  * Tidy up refs/dgit-fetch/ after dgit fetch (if successful).
  * Fix handling of in-archive copies.
  * Don't break if user has push.followTags=true.  Closes:#827878.
  * Arrange for the special dgit remote to be skipped by git fetch --all
    etc.  And no longer configure a fetch spec, since it won't work
    anyway.  Closes:#827892.
  * Allow local git config options to override user-global ones,
    as is proper.  Closes:#835858.
  * When generating patch filenames from titles, first transliterate
    them (lossily) to ascii.  Closes:#834807.

  Test suite:
  * When sbuild fails, do not crash due to sed not finding the log
    file.  Instead, simply tolerate the absence of the log file.
  * Put --no-arch-all in build-modes-sbuild act, not only its real_act.
    Cosmetic change only.
  * Set GIT_COMMITTER_DATE and GIT_AUTHOR_DATE and increment them
    explicitly in drs-push-rejects test.  This avoids date dependencies
    which can cause that test to fail on fast computers.
  * Remove some spurios .debs from the example_1.0.tar.
  * Increase sqlite_busy_timeout in debpolicy-dbretry, because old
    zealot is very slow and we need to give the other processes time
    to rollback and release the lock.
  * Test quilt single-debian-patch.
  * Provide `tartree-edit gitfetchinfo' etc. to help with comparing
    different test case git working tree tarballs.
  * Test dgit-repos-policy-debian with multiple (identical, as it happens)
    existing taints.
  * Provide better log output for certain failures.
  * Many new tests (especially for new functionality).
  * Add missing debhelper (>=8) to test suite's global Depends.
  * tstunt arrangements: Fix mishandling of PERLLIB, etc.
  * tstunt-parsechangelog: Produce Timestamp field (like official one
    does, now).
  * Do not fail when git requires --allow-unrelated-histories.

dgit (1.4) unstable; urgency=high

  Bugfixes:
  * Unbreak --dry-run (`exiting subroutine via next', broken in
    ac221d67, bug released in 0.22).
  * When running git-add in commit-quilty-patch, properly escape
    filenames (which git-add treats as glob patterns).
  * When running git-add in commit-quilty-patch, use -f and sometimes -A,
    so as to avoid being broken by any .gitignore, etc.
  * When quilt linearisation fails, print the right information in
    the error message.  (This has been broken forever.)
  * Cope properly with `3.0 (quilt)' with single-debian-patch.
    Closes:#796016.  (Still does not work with wheezy's dpkg-source, so
    no test case yet.)
  * With dgit sbuild, pass our -d before the user's arguments, so that
    the user can override it.  Closes:#796019.

  New checks and improved behaviours:
  * Detect and reject git trees containing debian/source/local-options
    or debian/source/local-patch-header.
  * In --dry-run mode, _do_ actually run dpkg-source --commit so that we
    actually do construct the quilt fixup commit; instead, honour
    --dry-run by avoiding pulling it back to your HEAD.
  * quilt-fixup checks that the git tree is clean, as for build-prep.

  Documentation:
  * In dgit(7), discuss binaries and documentation present in upstream but
    removed by rules clean.

  Test suite:
  * Run quilt-fixup with -wgf in distropatches-reject,
    so that we don't need build-depends.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sat, 22 Aug 2015 15:31:02 +0100

dgit (1.3) unstable; urgency=high

  Important bugfixes:
  * In option parser test `@ARGV' not `length @ARGV'.  Closes:#795710.
  * Properly quote package name when constructing regexp in
    complete_file_from_dsc.  Closes:#795736.  Also, grep the code for
    likely similar problems elsewhere and improve a (harmless) instance in
    dgit-repos-server.

  Other improvements:
  * If a .orig in .. is a symlink, hardlink the link target into our
    private unpack directory, rather than the link itself (since latter
    won't work if the symlink is relative).  Closes:#795665.
  * Test suite: Fix t-restriction-x-dgit-schroot-build in non-adt mode.
  * Infrastructure: Improve an error message in dgit-repos-policy-debian.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 16 Aug 2015 17:51:02 +0100

dgit (1.2) unstable; urgency=high

  Improvements:
  * Honour *.clean-mode configuration setting for --clean= mode.
  * No longer require option values to be cuddled: support `--opt val' and
    `-o val'.  Closes:#763332.

  Manpages:
  * Fix typos.
  * Document that tags are in DEP-14 format, and that they
    are used for authenticating pushes.
  * Correct cross-reference to point to browse.d.d.o.
  * Move dgit.default.* to main CONFIGURATION section.

  Administrivia:
  * Add missing close of #793060 to changelog for version 1.1.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Fri, 14 Aug 2015 18:27:20 +0100

dgit (1.1) unstable; urgency=medium

  Bugfixes:
  * When source package contains things called .git (even files, and even
    in subdirectories), remove them.  Closes:#793671.
  * Work around curl -sS -I printing `HTTP/1.0 200 Connection established'
    before the actual header, so dgit works with https_proxy set (!)
  * --new is needed for read access to packages in NEW, too.  Document
    this, and make it work properly.
  * Work around #793471 (madness with $SIG{__WARN__} and Perl's system
    builtin): move $SIG{} setting into setup_sigwarn in Dgit.pm, and
    check getppid.
  * When invoking git-buildpackage via dgit gbp-build, consider our
    command line arguments when massaging the dpkg-buildpackage arguments,
    so that we don't end up giving dpkg-buildpackage contradictory
    instructions.
  * Cope with new git-buildpackage which provides gbp, rather than the
    eponymous command, on PATH.

  Configurability:
  * Honour dgit-distros.DISTRO.cmd-CMD and .opts-CMD.  Closes:#793427.
  * Make configuration able to prevent dpkg-mergechangelogs setup.
  * Provide dgit setup-new-tree (like dpkg-setup-mergechangelogs
    but only does it if not disabled in config).
  * Set up git user.email and user.name from distro access config
    or DEBEMAIL/DEBFULLNAME.  Closes:#793410.
  * When key to use not specified any other way, use the debian/changelog
    trailer line.  Closes:#793423.
  * Honour --git= (mostly).

  Documentation:
  * Fix some manpage typos.  [ Richard Hartmann ]
  * Manpage said that --clean=check was -wn but that is --clean=none;
    correctly document that --clean=check is actually -wc.
  * Document that up to -DDDD (not just -DD) is meaningfully different.
  * Document that -cname=value applies only for this run.
  * Improve manpage comment about defining a new distro.
  * Document that --quilt=linear is the default for Debian.
  * Fix a formatting problem in --build-products-dir= doc.
  * In manpage, do not seem to imply that NMU should be of only one
    new commit.
  * Qualify to Debian the manpage comment about how to do NMU.
  * In discussion on how to start using dgit when already using git, do
    not imply/assume that existing git history will have identical trees
    to dgit history.
  * Remove stray sentence in config section of manpage.
  * Manpage: Clarify wording of readonly config.
  * Manpage: Better cross-references for -k and keyid.
  * dgit(7): No longer say that dgit-repos lives on Alioth.

  Improvements:
  * Introduce more sophisticated protocol negotiation for rpush.
  * Do not quote `:' in shellquote.
  * Print a supplementary message when push fails, giving advice to
    the user about how to retry.  Closes:#793144.
  * Slurp in entire git config, for better performance.
  * Rename `git-build' operation to `gbp-build' to make it clearer what
    it's for.  Keep the old name as an alias.
  * Show `dgit sbuild' in usage message.
  * When we are using dpkg-buildpackage to clean before using it to also
    do the build, let it do its cleaning thing as part of its run, rather
    than running it twice.  When we are _not_ supposed to be using
    dpkg-buildpackage to clean, but we are running it to do the build,
    pass -nc.  Closes:#793060.
  * Also suppress spurious runs of the clean target when building using
    git-buildpackage.
  * When exec fails, always print the program name in the error message.

  Infrastructure:
  * Infrastructure: Get mirroring right for fresh repos of existing
    packages (!)

  Packaging, cleanups, debugging and test suite:
  * Fix Vcs-Git and Vcs-Browse to refer to chiark.  (The dgit-repos on
    alioth aren't suitable right now because the master there can
    currently only be updated with an actual upload, ie dgit push.)
  * Make warnings fatal in dpkg-repos-admin-debian, dgit-ssh-dispatch
    (using setup_sigwarn).
  * tstunt/dpkg-parsechangelog: Make warnings fatal (directly).
  * tstunt/dpkg-parsechangelog: Do not complain if PERLLIB is empty.
  * Test suite: Honour DGIT_TEST_DEBUG=''.
  * With -DDDD, print out all gitcfg references (copious!)
  * Fix a debug message in the obsolete sshpsql archive access driver.
  * Test suite: More automatic enumeration of tests.
  * Test suite: Provide tests which check that all our various build
    operations run the right targets as expected (ie, that we are massaging
    the arguments to dpkg-buildpackage, and suppressing our clean target,
    etc., correctly).

dgit (1.0) unstable; urgency=medium

  Improvements:
  * Switch to new production git repositories for reading.
    (this can no longer divert to alioth).  Public readonly access
    now works.  Closes:#791447.
  * Memoise git config lookups (big speedup!)
  * Provide -wdd aka --clean=dpkg-source-d.  Closes:#792433.
  * Provide -wc aka --clean=check.

  Manpage updates:
  * Remove some obsolete caveats from BUGS.
  * Reorganise and complete the configuration section.
  * Remove obselete comment about DMs not being able to push.
    We have, for now, a way to add keys manually.  Closes:#720173.

  Access machinery:
  * Remove configuration relating to alioth.
  * Provide for different access mechanisms when pushing.
  * Provide for configurable git url suffix.
  * Allow git-url to be '' to force fallback to git-proto etc.
  * Provide for checking git presence via http[s].
  * Do some quoting on debug output (needed if the server might not
    be trustworthy and might send us bad stuff).
  * Talk to push.dgit.debian.org, rather than the .debian.net alias.

  Infrastructure:
  * Provide for mirroring git updates to a different server.
  * Provide cgit-regen-config command for cgi-grnet-01.
  * Make dgit-ssh-dispatch not spew (harmless) warnings if caller
    tries for a shell session (ie SSH_ORIGINAL_COMMAND not set).

  Cleanups:
  * Remove an obsolete comment from the code.
  * Improve an error message from dgit-repos-policy-debian.
  * Test suite: Break out t-make-hook-link.
  * Fix a manpage typo.

dgit (0.30) unstable; urgency=high

  INCOMPATIBLE CHANGES:

  * Client uses new infrastructure:
    - Check for new dgit git service on dgit-git.debian.net (ie
      gideon.debian.org), with transition plan based on diversion feature.
      Closes:#720172.
    - Old versions of dgit will stop working when the server-side handle is
      pulled.

  * dgit git trees no longer contain .pc for format `3.0 (quilt)' source
    packages.  Closes:#764606.
    - It is deleted whenever we find it.
    - Older versions of dgit will choke on trees without .pc.
    - (When doing quilt fixup, we recreate a suitable .pc in a temporary
      directory so that we can do dpkg-source --comit.)

  * All users are urged to upgrade ASAP.

  Other significant improvements:

  * When generating quilt patches, try to linearise the git history into a
    series of individual new patches for debian/patches.  Closes:#770710.

  * When receiving a push with dgit-repos-server, update the server's
    refs/heads/master if we are pushing to what the distro regards as a
    relevant branch, and the push would ff master.  Closes:#728209.

  * For non-Debian distros, distro version release tags contain distro
    name a la DEP-14 (rather than hardcoding `debian/').

  * Set up a merge driver for debian/changelog.  Closes:#769291.

  * --clean=git and --clean=none cause dgit to pass -nc to
    dpkg-buildpackage, suppressing calls to the package's clean target.
    Also, expand the documentation in this area slightly.  Closes:#768590.

  * Provide --clean=git-ff (aka -wgf), which is useful for dgit itself (!)

  Minor improvements:

  * Reduce some noise output and improve the clarity of some messages.
  * Be more careful about tag updates during fetch: only update tags
    referring to uploads to distro we are trying to fetch from.
  * Change realpath dependency to `coreutils (>= 8.23-1~) | realpath'
    (Closes:#786955.)

  Bugfixes:

  * Fix handling of rmadison-based and gitless distros (e.g., Ubuntu).
  * Add missing `gpgv' to test dependencies in debian/tests/control.
  * Strip `-b <branch>' from contents of Vcs-Git header, when setting up
    the vcs-git remote.  Closes:#759374.
  * Do not offer wget as an alternative dependency to curl.  We always
    unconditionally invoke curl and have no code to use wget.
    Closes:#760805.
  * Complain about lack of cuddled values for value-taking single-letter
    options, rather than thinking the user meat an empty value.
    Closes:#763332.
  * Reject (rather than ignoring) further options merged witth -wn, -wg,
    -wd.
  * Fix inaccurate error message when archive's git hash is not an
    ancestor of git repo's git hash.
  * Detect and bomb out on vendor-specific `3.0 (quilt)' patch series.
  * Fix the rules clean target to remove test results and output.

  Documentation improvements:

  * Break out dgit(7) from dgit(1).
  * Provide example workflow for dgit rpush.  Closes:#763334.
    (Also part of the fix for #768470.)
  * Document that dgit repos are cloneable with git, in dgit(1)
    section MODEL.  [Andreas Barth.]  Closes:#768470.
  * Better documentation for quilt series handling.
  * Document under `dgit push' that it is best to build with dgit too.
    Closes:#763333.
  * Other minor clarifications and improvements.

  Behind-the-scenes work:

  * Use ftpmasterapi archive query method.
    (Closes:#727702.  Also partly obsoletes #768470.)
  * New dgit-infrastructure binary package containing dgit-repos-server et
    al.  Client users probably don't want this stuff.  Also, it provides a
    convenient way to publish the dependencies.
  * Many many bugfixes to the server side (dpkg-repos-server et al.).
  * Add :..; prefix to ssh remote commands, for the benefit of future
    forced command wrappers.  Implicitly, this defines a new ssh-based
    command protocol.  Closes:#720174, #720175.
  * Distro access configuration handling changes (should not be noticeable
    to most users).
  * In places, significant restructuring or tidying up.
  * Turn all perl warnings into errors using $SIG{__WARN__}.

dgit (0.22.1) unstable; urgency=high

  * Use Dpkg::Version::version_compare everywhere, not
    Dpkg::Version::version_compare_string.  The latter is entirely wrong,
    meaning that dgit would get many version comparisons wrong.
    Closes:#768038.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 04 Nov 2014 12:46:40 +0000

dgit (0.22) unstable; urgency=medium

  Bugfixes:
  * Clone removes destination directory on error.  Closes:#736153.
  * Work with wheezy-backports (and keep squeeze-backports working too).
    Closes:#736524.
  * Work in read-only no-git-history mode with Ubuntu.  You still have
    to pass -dubuntu.  Closes:#751781.
  * Use mirror.ftp-master.debian.org DNS alias rather than coccia.
    Closes:#752602.
  * Check hashes of files ourselves rather than running dget to
    re-retreive the .dsc.
  * Check SHA-256 of .dsc against hash from archive_query (ie projectb)
    rather than letting dpkg-source do a signature verification.
    Closes:#737619.  Closes:#737625.
  * Treat .dsc as bytes, just like everything else, rather than letting
    HTTP::Message convert it to a Perl unicode string which the rest of
    the program mishandles.  Closes:#738536.

  Minor improvements:
  * Include canonicalised suite name in signed tag message.
  * Mention cross-version dgit rpush incompatibility in manpage.
  * Check for rpush protocol version incompatibility and crash early
    if incompatible.
  * New script tests/using-intree for running tests on the source tree.
  * Do not spew diff output to terminal (by default).  Print sensible
    message instead.  Closes:#736526.
  * Print better message for lack of configuration settings.
  * Document that dgit rpush needs gnupg and your public key on the build
    host.  Closes:#736529.
  * Fix a manpage reference to `--dget=' where `--dgit=' was intended.
  * Provide t-archive-process-incoming and t-archive-query subroutines for
    regression test scripts to use.
  * Print better message for unknown operations.
  * Provide `dgit clean'.  Closes:#736527.
  * When cloning, set up a remote `vcs-git' from the package's Vcs-Git
    (and put an appropriate caveat in the manpage).  Closes:#740687.
    Closes:#740721.
  * Improve error message for .dsc having already been signed (iff
    using libdpkg-perl 1.17.x).  Closes:#731635.
  * Improve error message for .dsc parsing failures more generally.
  * Better reporting of child exit statuses (esp. deaths due to signals).
  * In rpush, on protocol error talking to build host, check if the
    subprocess died and report differently if so.  Closes:#736528.
  * Fixed a manpage typo.
  * When tests invoke dgit, use --dgit= so that subprocesses use our
    dgit rather than system one.
  * Add a test for dgit rpush.

  Major new feature, currently stalled awaiting server infrastructure:
  * dgit-repos-server: New program for receiving signed-tag-based
    pushes.  Corresponding support in dgit itself, but not currently
    used by default for any distro.
  * Bring forward push of the version tag ref so it happens alongside
    the push of the suite branch ref.
  * New git-check and git-create methods "true" which are no-ops.
  * test-dummy-drs `distro': for testing dgit and dgit-repos-server.

dgit (0.21) unstable; urgency=medium

  Bugfixes relating to unclean trees:
  * Run a clean (of the specified type) before any build operation; do
    this with `dpkg-buildpackage -T' clean if necessary, so -wd now works
    with all the building methods.
  * Refuse to do quilt fixup (explicitly requested, or as a result of
    build) if the tree contains ignored files.  Closes:#731632.

  Error message improvements:
  * Use failedcmd to report errors when ssh psql fails.  Closes:#734281.
  * failedcmd prints $us, not $_[0] - ie, dgit doesn't pretend,
    in the error message, to be its child.
  * Do not report the (irrelevant) $? when madison parsing fails.

  Better workflow flexibility:
  * Provide --build-products-dir option (and corresponding semantics
    for -C) to specify where to find the files to upload.  Closes:#731633.

  Support for Debian backports suites:
  * New quirks infrastructure in configuration and internals,
    for suites (or perhaps distros) which are a bit like others.
  * Use correct default archive location.
  * Compute "-v" option default value correctly.
  * Closes:#733954.

  Packaging improvement:
  * Add `Testsuite: autopkgtest' to debian/control.  (This will only have
    the right effect with recent enought dpkg; it will generate a harmless
    warning with earlier versions of dpkg.)

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 19 Jan 2014 02:14:25 +0000

dgit (0.20) unstable; urgency=high

    what value to use for -v<version> by default.  Closes:#732781.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sat, 21 Dec 2013 19:13:56 +0000

dgit (0.19) unstable; urgency=low

  Testing facilities:
  * Provide "test-dummy" distro with "dummycat" access method.
  * Provide a selection of autopkgtest (DEP-8) tests.

dgit (0.18.2) unstable; urgency=high

  Bump archive upload urgency to high.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 24 Nov 2013 17:42:57 +0000
dgit (0.18.1) unstable; urgency=low

  Bugfixes:
  * sshpsql archive query method passes LANG=C.  Closes:#729788.
  * Subcommand program or argument options containing hyphens work.
    (Eg, --dpkg-buildpackage:blah was previously incorrectly rejected.)

  Packaging fixes:
  * Depend on dput.
  * Depend on curl | wget, as dget needs one of those.  (The dput package,
    which contains dget, doesn't require them because dput itself works
    without.)

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 24 Nov 2013 17:36:03 +0000

dgit (0.18) unstable; urgency=low

  Major new feature:
  * Remote push (dgit rpush), a la debsign -r.  Closes:#721185.

  Improved behaviours:
  * dgit build, by default, uses the archive to find out what the correct
    -v<version> option is to pass to dpkg-genchanges.  Closes:#727200.
  * Abolish the sshdakls method and replace it with sshpsql: that is, ssh
    (to coccia, by default) and run sql commands on the ftpmaster
    database.  This is faster and has fewer bugs but is vulnerable to db
    schema changes.  Closes:#726955.  Closes:#720170.  Closes:#720176.
  * When generating git tags, quote the (uncanonicalised) changelog's
    Distribution field as the suite.
  * Command execution reports from --dry-run go to stderr.

  Other new features:
  * Support --gpg=... to provide a replacement command for gpg.
  * Support --ssh=... and --ssh:... to affect how we run ssh.

  Bugfixes:
  * When using sbuild, pass the arguments to mergechanges in the right
    order so that we use the correct Description (the _source one,
    not the one from sbuild which didn't get e.g. -v<version>).
  * push actually takes an optional suite, like it says in the synopsis.
    Closes:#727125.
  * Fix dgit --damp-run sbuild to actually work.
  * Fix the "shellquote" internal subroutine.  The bugs in it ought not to
    have caused any real trouble in previous versions of dgit.

  Documentation and message fixes:
  * manpage: Clarify comments about orig tarballs.  Closes: #723605.
  * manpage: Remove comment in BUGS about lack of policy docs
    for Dgit field, which is specified now.  Closes:#720201.
  * manpage: Make discussion of --existing-package less scary.  The
    default archive access method no longer needs it.  Closes:#720171.
  * Mention "git merge", not "git-merge", in helpful message.
    Closes:#725632.

  Internal and debugging improvements:
  * Report chdir actions in debugging output.
  * Improvements to implementation of --dry-run and --damp-run.
  * Some code motion and cleanups.

  Note: changelog entries for the following versions, which were uploaded
  to Debian experimental, have been collapsed into this single entry:

dgit (0.17) unstable; urgency=high

  * Do not grobble around in .git/refs/; instead, use git-show-ref.
    This avoids breaking when git makes packed refs.  Closes:728893.
  * Clarify error message for missing refs/remotes/dgit/dgit/<suite>.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 07 Nov 2013 00:02:47 +0000

dgit (0.16) unstable; urgency=high

  * Format `(3.0) quilt' fixup does not mind extraneous other files
    in the build tree (e.g., build products and logs).  Closes: #727053.
  * Set autoflush on stdout, to get better ordering of debugging
    etc. output when stdout is redirected.
  * New --damp-run mode, for more convenient and fuller testing etc.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Tue, 22 Oct 2013 13:06:54 +0100

dgit (0.15) unstable; urgency=low

  * Better handling of packages pushed using dgit and stuck in NEW.
    (And, use of `--new' is not needed with fetch.)  Closes: #722199.
  * More comprehensive warnings in many cases of archive skew.
  * Implement `dgit help' as well as `--help'.  Closes: #721661.
  * Provide `dgit version' and `--version'.  Closes: #721654.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 12 Sep 2013 00:14:05 +0100

dgit (0.14) unstable; urgency=low

  * Include package name in tag message.
  * Create directory .git/dgit when needed during build.  Closes: #721428.
  * Add Vcs-Git and Vcs-Browser [Richard Hartmann].  Closes: #721404.
    These fields refer to the development branch, "master", on alioth,
    not to the dgit suite refs (which are not accessible to git clone).

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 01 Sep 2013 18:30:44 +0100

dgit (0.13) unstable; urgency=low

  * Reuse already-downloaded .orig files after checking their hashes.
    Closes: #720526.  (This introduces a dependency on Digest::SHA.)
  * Do not always pointlessly fetch the .dsc twice.  (That code was
    erroneously duplicated during editing, apparently.)
  * Remove DGET_UNPACK from the environment in case the user has set it.
  * Remove scary warning from Description.
  * When uploading to Debian, tell dput to upload to "ftp-master".  This
    avoids problems with derivatives whose dput has a different default.
    Closes: #720958.
  * Fix some bugs in dgit fetch --dry-run which made dgit push
    --dry-run often not work at all.
  * Update the local tracking branch for the dgit remote, when pushing.
    Closes: #720956.
  * Fix references in manpage to old Vcs-Dgit-Master field name.
  * Reorganise manpage sections to be in a more conventional order.
  * New manpage section on FILES IN THE SOURCE PACKAGE BUT NOT IN GIT.
    Closes: #721186.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 29 Aug 2013 00:27:23 +0100

dgit (0.12) unstable; urgency=low

  * Cope with packages with epoch.  Closes: #720897.
  * Improve error message for non-fast-forward push.  Closes: #720896.
  * New --ignore-dirty option to skip noncritical check.  Closes: #720895.
  * New --no-quilt-fixup option to suppress quilt fixup.  RTFM.
  * Add Closes line for #720595 to changelog entry for 0.11.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 26 Aug 2013 16:50:39 +0100

dgit (0.11) unstable; urgency=low

  * Location of dgit-repos is now git.debian.org:/git/dgit-repos/repos.
    Closes: #720525.  The rename on the server side will break older
    versions of dgit.
  * Fix bug which would make quilt patch fixup fail if git status
    produced "M" lines.
  * Autogenerated quilt patch fixup patch Description contains several
    recent git commits, rather than implying that the patch corresponds
    exactly to the top git commit.
  * Use "ftp.debian.org" not "http.debian.net" as the default Debian
    archive.  (http.debian.net tends to defeat certain kinds of cacheing,
    and can also have more skew.)
  * dgit build uses dpkg-buildpackage; there is a dgit git-build
    for using git-buildpackage.  Closes: #720595.
  * Better error message for use of UNRELEASED suite.  Closes: #720523.
  * Do not canonicalise suite more than once.  Related to: #720526.
  * Fix a badly open-coded copy of check_not_dirty.  Closes: #720524.
  * Fix some bugs in building (eg build-source would fail to do the quilt
    fixup; the --clean check in build was wrong).
  * Add missing dependency on realpath.
  * git-build (git-buildpackage wrapper) does not bother canonicalising
    the suite if --git-ignore-branch is used.

dgit (0.10) unstable; urgency=low

  * Create .pc/applied-patches - do not empty it (!)

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 25 Aug 2013 00:51:50 +0100

dgit (0.9) unstable; urgency=low

  * New cleaning arrangements.
  * More comprehensive workaround for `3.0 (quilt)'.
  * In push, double-check the .changes against the changelog.
  * Better error when source package contains .git.  Closes: #720555.
  * Change our .dsc field name to `Dgit'.  Relevant to #720201.
  * Fix bug handling our synthetic merges when we see them in
    the remote suite branch.
  * `3.0 (quilt)' fixup creates .pc/applied-patches since modern
    dpkg-source creates it even though old ones didn't always.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sat, 24 Aug 2013 18:49:02 +0100

dgit (0.8) unstable; urgency=low

  * Fix comparison of archive's .dsc's hash and git branch head
    to DTRT.
  * When creating repos in dgit-repos (using the ssh-cmd method),
    copy _template rather than using mkdir and git init.
    Closes: #720522.
  * In push, do git fetch as well as archive fetch, or archive
    fetch can fail.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Fri, 23 Aug 2013 12:24:09 +0100

dgit (0.7) unstable; urgency=low

  * If dak ls, or rmadison, reports multiple versions, look for them
    all, and pick the newest .dsc that doesn't give 404.
  * Manpage formatting fix.
  * Name the local remote tracking branch remotes/dgit/dgit/<suite>
    so that we avoid a warning from git about ambiguous branch names.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 22 Aug 2013 18:29:10 +0100

dgit (0.6) unstable; urgency=low

  * Allow fetching when archive has out-of-date git hash in .dsc.
    Closes: #720490.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 22 Aug 2013 16:02:10 +0100

dgit (0.5) unstable; urgency=low

  * Upload to unstable, as this version mostly works.  (All the RC
    bugs of which I'm aware are now properly represented in the BTS.)

dgit (0.4~pre2) experimental; urgency=low

  * Mangle debian/<version> tags the way git-buildpackage does
    (as of git-buildpackage 0.5.5, 3c6bbd0f4992f8da).
  * Support dgit-distro.<distro>.keyid config option.
  * Revert change to ssh to alioth CNAME, as the recommended CNAME
    is to something with no write access to the fs and the new CNAME
    has not yet been set up.  This reintroduces #720172 :-/.
