dgit (1.1~~) unstable; urgency=low

  * 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.)
  * 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 -DDD (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.
  * Infrastructure: Get mirroring right for fresh repos of existing
    packages (!)
  * --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.
  * Make warnings fatal in dpkg-repos-admin-debian, dgit-ssh-dispatch
    (using setup_sigwarn).
  * Make warnings fatal in tstunt/dpkg-parsechangelog (directly).
  * When source package contains things called .git (even files, and even
    in subdirectories), remove them.  Closes:#793671.
  * Introduce more sophisticated protocol negotiation for rpush.
  * Do not quote `:' in shellquote.
  * Test suite: Honour DGIT_TEST_DEBUG=''.

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

  * Use newest (not oldest) version currently in suite when calculating
    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.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Wed, 27 Nov 2013 18:27:17 +0000

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:
    0.18~experimental2 0.18~experimental1

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.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Sun, 25 Aug 2013 17:00:43 +0100

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.)

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 22 Aug 2013 15:38:00 +0100

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 :-/.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 22 Aug 2013 15:31:17 +0100
