dpkg 1.18.23ubuntu1 source package in Ubuntu

Changelog

dpkg (1.18.23ubuntu1) artful; urgency=medium

  * Merge from Debian (LP: #1654905, #1652945); remaining Ubuntu changes:
    - Change native source version/format mismatch errors into warnings
      until the dust settles on Debian bug 737634 about override options.
    - Add DPKG_UNTRANSLATED_MESSAGES environment check so that higher-level
      tools can get untranslated dpkg terminal log messages while at the
      same time having translated debconf prompts.
    - Special-case arm{el,hf} ELF objects in Shlibs/Objdump.pm for multilib.
    - Map unqualified package names of multiarch-same packages to the native
      arch instead of throwing an error, so that we don't break on upgrade
      when there are unqualified names stored in the dpkg trigger database.
    - Apply a workaround from mvo to consider ^rc packages as multiarch,
      during the dpkg consistency checks. (see LP: 1015567 and 1057367).
  * scripts/Dpkg/Vendor/Ubuntu.pm: Drop obsolete hardening-wrapper control.
  * scripts/Dpkg/Vendor/Debian.pm: Adjust PIE builtin architecture list.

dpkg (1.18.23) unstable; urgency=medium

  * Handle unmatched arch-qualified virtual packages in dpkg-genbuildinfo,
    instead of letting perl die. Closes: #849944
  * Declare .buildinfo format as stable with version 1.0.
  * Do not depend on cxxabi.h to have declared __cxa_pure_virtual, use
    the same “__cxxabiv1” namespace as specified in the C++ ABI, instead
    of using the “abi” alias intended for use by userland.
    Thanks to Jörg Sonnenberger <email address hidden>.
  * Add a comment on any C code switch case that falls through. Fixes new
    gcc-7 warnings.
  * Use snprintf() instead of sprintf() in libdpkg when constructing the ar
    member header, as we might overflow depending on the input data.
  * Portability:
    - Do not redeclare sys_siglist in libcompat when the system does so.
      Thanks to Thomas Klausner <email address hidden>.
    - Rename err variable to ret in start-stop-daemon as the former is a
      function on BSDs.
    - Use 5-argument kvm_getprocs() call form on OpenBSD in start-stop-daemon.
    - Use correct struct kinfo_proc ruid submember name on NetBSD in
      start-stop-daemon.
    - Define _KMEMUSER for NetBSD to get declarations for various
      struct kinfo_proc members in start-stop-daemon.
  * Perl modules:
    - Do not special case EM_SPARC32PLUS for NetBSD in Dpkg::Shlibs::Objdump,
      the code has been fixed in NetBSD as that situation could not happen.
    - Fix read() error handling in Dpkg::Shlibs::Objdump::get_format() to
      gracefully ignore non-ELF files again. Closes: #854536
    - Emit an explicit warning from Dpkg::Shlibs::Objdump::Object::analyze()
      for unknown executable formats instead of relying on objdump doing so.
    - Do not parse bogus ELF binaries in Dpkg::Shlibs::Objdump::get_format().
      Reported by Niels Thykier <email address hidden>.
    - Add ‘.mnt-ignore’ to the default ignore lists in Dpkg::Source::Package,
      as we were already ignoring the ‘_MTN’ pathnames. Closes: #855450
      Thanks to Nicolas Boulenguez <email address hidden>.
    - Mark kfreebsd-amd64, kfreebsd-i386, sparc and sparc64 architectures as
      having gcc builtin PIE in Dpkg::Vendor::Debian.
    - Switch PIE handling in Dpkg::Vendor::Debian to have no default (!) and
      delegate the setting to gcc or an explicit request by a user. This is
      needed to cope with the general PIE brokenness situation in Debian, and
      the current specific brokenness of a Debian gcc patch mangling the dpkg
      build flags. Closes: #848129, #845550
  * Documentation:
    - Clarify the requirements for deb-conffile(5) pathnames. Closes: #854417
      Proposed by Dieter Adriaenssens <email address hidden>.
    - Document dpkg-source --before-build and --after-build in --help output.
    - Document dpkg-buildpackage --ignore-builtin-builddeps in --help output.
  * Build system:
    - Check <sys/proc.h> by also including <sys/param.h>, on several BSD
      systems the header is not self-contained.
    - Handle libmd implementations built into system libc, as found on some
      BSD systems.
    - Do not fail on missing compression libraries or headers on automatic
      detection mode. Regression introduced in dpkg 1.18.14.
  * Test suite:
    - Use the detected perl interpreter instead of a random one from PATH.

  [ Guillem Jover ]
  * Turn status file parser errors on bogus field blank lines into warnings,
    otherwise the system cannot be easily recovered from. Regression
    introduced in dpkg 1.16.1. Reported by Jay Freeman <email address hidden>.
  * Perl modules:
    - Mask ARM ABI bits in the ELF processor flags in Dpkg::Shlibs::Objdump.
      These are too unreliable to be used for exact matching. Closes: #853793

dpkg (1.18.21) unstable; urgency=medium

  [ Guillem Jover ]
  * Revert "Generate Testsuite-Restrictions fields from the test restrictions
    in dpkg-source into .dsc files". This change is contentious and should
    have been discussed more widely. Given that this has been live only for
    a couple of days, the impact should be minimal, but still something to
    take into account once and if this gets reintroduced. Closes: #852820
  * Perl modules:
    - Map alternative or old ELF machine types to canonical ones. We need
      those to match on the encoded ABI, otherwise dpkg-shlibdeps will not
      be able to find the objects.

  [ Updated man pages translations ]
  * German (Helge Kreutzmann).

dpkg (1.18.20) unstable; urgency=medium

  [ Guillem Jover ]
  * Add a new --no-sign option to dpkg-buildpackage, to make it possible to
    disable all signing in a future-proof way.
  * Make dpkg-buildpackage --unsigned-changes not sign .buildinfo either.
    This breaks the expectations of users and tools, because there was no
    way previously to request no signing at all. Closes: #852822
  * Perl modules:
    - Mask the machine bits for SH and MIPS in the ELF processor flags in
      Dpkg::Shlibs::Objdump. These do not define the ABI, and make the
      objects not match when they should, when looking for shared libraries
      from dpkg-shlibdeps.
    - Encode the ELF ABI as a big-endian byte stream, so that decoding for
      output gives meaningful results.
    - Disable the NFS-unsafe warning on Linux, as using flock() on NFS has
      been safe for some time now. Addresses: #677865 (on Linux)
  * Documentation:
    - Document the Built-For-Profile field in deb-changes(5).

dpkg (1.18.19) unstable; urgency=medium

  [ Guillem Jover ]
  * Stop emitting Built-For-Profiles from dpkg-gencontrol. The information
    is already provided in .buildinfo and .changes files, and including it
    in the binary packages makes them unreproducible even when the profile
    used would not alter its contents. Closes: #831524
  * Do not allow empty epochs and revisions in versions. When there's at
    least one colon or one dash, we should expect epoch and revision numbers.
  * Always set SOURCE_DATE_EPOCH in dpkg-buildpackage and dpkg-source. Use
    the current date if the changelog does not have one. Closes: #849081
  * Refactor update-alternatives pathname existence check into a new function.
  * Avoid useless repeated lstat()s in update-alternatives.
  * Only check for debian/tests/control file once in dpkg-source.
  * Generate Testsuite-Restrictions fields from the test restrictions in
    dpkg-source into .dsc files. Closes: #847926
    Based on a patch by Iain Lane <email address hidden>.
  * Improve the ELF ABI mismatch detector in dpkg-shlibdeps, by parsing the
    ELF header ourselves. While still not perfect (things like linux-i386 and
    hurd-i386 will still match), it will filter lots of previously matching
    objects that should have been ignored, and will work even when objdump
    does not know about the specific object details. Closes: #849913
  * Add initial support for DEB_BUILD_OPTIONS to dpkg-genbuildinfo. This will
    make it possible to enable or disable specific features that should be
    recorded in the .buildinfo file. For now only “all” and “path” are
    supported. Closes: #848705
  * Add again the architecture from the filename to .changes files for any
    artifact with one. This reverts the change introduced in dpkg 1.18.11.
  * Fold the filtering and checksumming of files to distribute in a .changes
    file in dpkg-genchanges into the initial loop. This way we do not include
    architectures for artifacts we are not going to distribute, and do not
    unnecessarily recompute the checksums for artifacts like the sources.
  * Do not compute the architecture list twice in dpkg-genchanges.
  * Include .buildinfo files also for source-only uploads in dpkg-genchanges.
    Closes: #846164
  * Fix check for expected number of binary artifacts in dpkg-genchanges, to
    only take into account the artifacts that we are distributing.
  * Fix parsing of Pre-Depends and Depends in dpkg-genbuildinfo, so that
    the code parses both and not just the first to appear in the stanza.
    Based on a patch by Johannes Schauer <email address hidden>.
  * Add support for signed .buildinfo files to dpkg-buildpackage. Add new
    -ui and --unsigned-buildinfo options. Closes: #843925
  * Portability:
    - On GNU/Hurd try to use the new process executable name attribute from
      libps, to properly match on start-stop-daemon --exec.
  * Perl modules:
    - Fix Debian architecture wildcard parsing so that matching four-tuple
      matchings work. Missed in dpkg 1.18.11.
      Reported by Julian Andres Klode <email address hidden>.
    - Add new import tags for Dpkg::Arch.
    - Abort on EOF in patch name prompt in Dpkg::Source::Package::V2,
      instead of getting into an infinite loop. Closes: #851441
    - Call anonymous subs via -> operator instead of casting with &, and fix
      bogus POD documentation to match the code.
    - Add new Auto-Built-Package field to Dpkg::Control::Fields.
    - Add a new debug() reporting function, and switch code to use it.
    - Add new Dpkg::BuildOption parse_features() method refactored from
      Dpkg::Vendor::Debian.
  * Documentation:
    - Cleanup software requirements in README.
    - Move control member file references from dpkg(1) to deb(5).
    - Fix typos in docs and code comments.
    - Document Auto-Built-Package field in deb-control(5).
  * Build system:
    - Disable disk pre-allocation by default, but let the builder re-enable
      it via a new configure option. This has been causing major performance
      issues on "modern" filesystems.
  * Packaging:
    - Add debsig-verify to dpkg Suggests. The code optionally supports this
      specific signed .deb verification program.
      Prompted by Stuart Prescott <email address hidden>.
  * Test suite:
    - Generate and check all currently possible architecture wildcards.
    - Correctly iterate over all default and passed .dsc template substvars.

  * Documentation:
    - Document DPKG_DATADIR in an ENVIRONMENT section in dpkg-architecture(1).
    - Add a rationale for the purpose of Testsuite-Triggers in dsc(5).
      Prompted by Mattia Rizzolo <email address hidden>.
  * Packaging:
    - Revert the perl to perl:any dependency change in libdpkg-perl, as that
      breaks debootstrap in stable (jessie), testing (stretch) and unstable,
      which do not support arch-qualified dependencies. We'll have to live
      with the Multi-Arch hinter being unhappy for now.

  * Handle empty versions on validation in dpkg-maintscript-helper as they
    are optional. Regression introduced in dpkg 1.18.16. Closes: #848422
  * Validate versions too in dpkg-maintscript-helper symlink_to_dir and
    dir_to_symlink commands.
  * Improve logic to identify packages owning a library in dpkg-shlibdeps,
    by handling the same library appearing more than once on the filesystem
    Thanks to Raphaël Hertzog <email address hidden>. Closes: #843073
  * Documentation:
    - Clarify that dpkg-buildpackage does not run «dpkg-source --before-build»
      when using the -T option. Closes: #649531
    - Document that dpkg sets DPKG_ADMINDIR on maintainer script environment.
  * Packaging:
    - Do not let dh_perl insert a dependency for libdpkg-perl, because it
      emits perl instead of perl:any. Instead hardcode a perl:any dependency
      to comply with the perl policy and make the Multi-Arch hinter happy.

dpkg (1.18.16) unstable; urgency=medium

  [ Guillem Jover ]
  * Add support for specifying multiple targets on «dpkg-buildpackage -T»
    which will be run successively. Closes: #671074
  * Reject empty upstream versions in C and perl code. These are not permitted
    by deb-version(5), but the code was letting those through.
  * Use lzma_cputhreads() instead of sysconf(_SC_NPROCESSORS_ONLN) as the
    former is way more portable.
  * Automatically decrease xz encoder threads to try to not exceed available
    memory limits. This should alleviated the insane requirements of memory
    needed on 32-bit architectures with many cores, which results in more
    than the userspace addressable memory, when using settings such as
    -z9 and/or -Sextreme in dpkg-deb. Closes: #846564
  * Add new dpkg --validate-<thing> commands to validate the syntax of
    various <thing>s, where the current list is «pkgname», «trigname»,
    «archname» and «version».
  * Use the new dpkg --validate-version command in dpkg-maintscript-helper,
    instead of abusing the --compare-versions command to perform version
    validation. Closes: #844701
  * Allow readlink(2) to return a size smaller than stat(2) in dpkg. Some
    bogus filesystems do not return the actual symlink size in st_size,
    which contradicts POSIX. But allowing the case where the returned size
    is smaller than the one used to allocate memory is harmless, although
    suspect. Let it through, but still print a warning so that users can
    install stuff but are reminded they need to get a fixed filesystem in
    place. This has affected at least ecryptfs in the past and now
    file-based encryption support in ext4 on Android N.
  * Add new dpkg-query virtual field source:Upstream-Version. Closes: #844348
  * Perl modules:
    - Whitelist DPKG_GENSYMBOLS_CHECK_LEVEL, DPKG_ROOT, DPKG_ADMINDIR and
      DPKG_DATADIR environment variables in Dpkg::Build::Info.
  * Documentation:
    - State the current working directory used when running dpkg-buildpackage
      hooks.
    - Add a new ENVIRONMENT section to dpkg-gensymbols(1) and document
      DPKG_GENSYMBOLS_CHECK_LEVEL there.
    - Fix bogus description of --force-confmiss in dpkg(1). Regression
      introduced in 1.16.4. Reported by Sven Joachim <email address hidden>.
      Closes: #846395
    - Update dpkg-parsechangelog parser options. The options specific to
      the changelog parser program did not get updated when the parser got
      switched to be a perl module. Missed in dpkg 1.18.8. Closes: #848189
  * Build system:
    - Enable compression libs also in automatic check mode in configure.
    - Honor DPKG_DATADIR again in the installed Dpkg modules. This was an
      explicit public interface, documented in the man page.

  * Improve PIE flags support:
    - Do not enable PIE when linking static programs. glibc-based systems
      do not support this combination and produce very bogus output.
      Proposed by Szabolcs Nagy <email address hidden>. Closes: #843714
  * On source builds add 'source' to the Architecture field in the
    .buildinfo file in dpkg-genbuildinfo.
  * Add new Build-Date field to .buildinfo files.
  * Generate deterministic .buildinfo filenames in dpkg-genbuildinfo,
    following the same pattern as used for .changes files.
  * Bump .buildinfo Format to version 0.2.
  * Change dpkg-buildpackage -j and -J on “auto” mode to fallback to serial
    execution when we cannot infer the number of online processors on
    unsupported or exotic systems. This should be a safer mode of operation.
    Proposed by Simon McVittie <email address hidden>.
  * Only preallocate disk size in dpkg for unpacked files bigger than 16 KiB.
    Closes: #824636
  * Perl modules:
    - Validate architecture arguments in Dpkg::Deps deps_parse().
      Prompted by Johannes Schauer <email address hidden>.
  * Documentation:
    - Escape dashes in field names in dpkg-buildinfo(1).
  * Test suite:

  * Improve PIE flags support:
    - Rename the spec name cc1_options to self_spec.
      Suggested by James Clarke <email address hidden>
    - Do not set PIE options if they have been negated, and do not reset
      them if they have been requested.
    Closes: #843791, #843826
  * Fix use after free error in dpkg. It was trying to print messages that
    had already been freed as part of the database memory pool, causing in
    some cases segfaults when reporting the error summary at the end.
    Regression introduced in dpkg 1.18.11. Closes: #843874
  * Change default color behavior to auto.
  * Perl modules:
    - Fix confusing date parse error message in Dpkg::Changelog::Entry::Debian
      when the date contains “May”. Closes: #843829
      Thanks to Nishanth Aravamudan <email address hidden>.
    - New module Dpkg::Build::Info module refactored from dpkg-genbuildinfo.
      Requested by Johannes Schauer <email address hidden>.
  * Documentation:
    - Improve the DEB_BUILD_OPTIONS description in dpkg-buildpackage(1).
      And mention the parallel option there.
    - Explicitly mention in dpkg-buildpackage(1) that setting the number
      of parallel jobs to 1, restores the serial behavior.
      Prompted by Thorsten Glaser <email address hidden>.
  * Packaging:
    - List public Dpkg::Control::Tests module in libdpkg-perl description.
  * Test suite:
    - Do not fail tests on missing fakeroot, just skip them.
  * Build system:
    - Fix inversion logic in libmd configure check when requested explicitly.
    - Do not consider the compressor libraries available in configure if the
      headers are not usable.
    - Fix DPKG_BUILD_RELEASE_DATE to require DPKG_PROG_PERL, as it uses perl.
    - Change DPKG_BUILD_RELEASE_DATE to use perl instead of date(1) to
      format the timestamp, as the former is more portable.

  * Improve PIE flags support:
    - Retroactively document in the changelog that PIE is enabled by default
      on all supported architectures regardless of gcc doing so itself on a
      subset of them.
    - When emitting PIE flags on architectures where gcc does not inject
      those itself, do it via a specs file too, so that maintainers can
      use them unconditionally regardless of the object being compiled
      or linked.
    - When injecting -no-pie for linking via the gcc specs file also
      inject -fno-PIE.
    - Update the documentation.
  * Perl modules:
    - Do not try to load non-files in Dpkg::Dist::Files load_dir method.
      Fixes test failures on non-Linux architectures. Closes: #843436
  * Packaging:
    - Add missing Breaks on old libdpkg-perl to dpkg. Closes: #843429

  * Switch from non-freeing malloc to m_malloc on statdb slurping.
  * Switch from non-freeing malloc to m_malloc for invoke hooks.
  * Always reset the package in-core database when shutting down the package
    database journal.
  * Do not crash if we pass a NULL cip argument to setaction() in libdpkg.
  * Shutdown the package database journal in dpkg --get-selections.
  * Fix (deactivated) dpkg --command-fd to initialize and reset the files
    database on each action.
  * Implement source stanza substvars prefixed with S: in dpkg-gencontrol.
    These auto-generated variables map each source stanza field into an
    output substvar prefixed with “S:”.
  * Make dpkg-source generate reproducible source packages when run
    standalone, by honoring SOURCE_DATE_EPOCH.
  * Fix several short-lived memory leaks in update-alternatives.
    Reported by Helmut Grohne <email address hidden>.
  * Only set the error context message in libdpkg if it has been formatted
    correctly.
  * Return error in error_context_errmsg_format() only if the error message
    gets truncated. In case we have to use the emergency buffer because the
    previous vasprintf() call failed, we should only return an error code if
    the vsnprintf() call on the emergency buffer truncates the output.
  * Fix free() on uninitialized pointer in error_context_errmsg_format() in
    libdpkg. Regression introduced in dpkg 1.18.7. Closes: #842004
  * Move C++ support code into its own file.
  * Add replacement new and delete array operators to C++ support code.
  * Implement local abi::__cxa_pure_virtual. When using g++ if we provide our
    version of this function we can avoid the dependency on either libstdc++
    or libsup++.
  * Include missing <new> for new and delete operator declarations.
  * Do not log nor print duplicate dpkg removal action. We print
    “Removing <package> (<version>)” lines and log remove action twice
    when purging a package from frontends, because they usually first call
    --remove and then --purge sequentially. When purging a package which is
    already in config-files (i.e. it has been removed before), do not print
    nor log the remove action.
  * Remove default «.» from @INC before loading perl modules in perl code.
    Fixes CVE-2016-1238.
  * Give more information on --set-selections warnings. Closes: #842230
  * Add new DEB_*_ARCH_ABI and DEB_*_ARCH_LIBC variables to dpkg-architecture
    and architecture.mk Makefile fragment.
  * Do substvar instantiation just once in dpkg-gencontrol.
  * Fix dpkg-gencontrol to not update the files list file (debian/files)
    when printing to STDOUT (via -O).
  * Do not add architectures to .changes Architecture field for artifacts
    that are not a .deb or .udeb in dpkg-genchanges.
  * Add support for .buildinfo files:
    - Add new dpkg-genbuildinfo command.
    - Hook it into the dpkg-buildpackage machinery.
    Based on a patch by Jérémy Bobbio <email address hidden>. Closes: #138409
  * Enable dpkg-buildpackage -Jauto by default. Closes: #842845
  * Fix dpkg to not fail when removing non-existent backup files on read-only
    filesystems. Closes: #838877
  * Enable PIE on all supported architectures and handle PIE enabled by
    default in gcc. On architectures where gcc enables them by default,
    stop setting -fPIE and -pie, and set -fno-PIE and -no-pie when disabling
    «pie» via gcc specs files, so that we do not emit them on situations
    where it would be inappropriate. Closes: #835149
    Based on a patch by Bálint Réczey <email address hidden>.
  * Architecture support:
    - Add support for AIX operating system.
    - Add a version pseudo-field to the arch tables.
    - Internally represent Debian architectures as quadruplets.
  * Portability:
    - Cast off_t variables to intmax_t when printing them with "%jd".
    - Add missing <string.h> include in libdpkg.
    - Cast strlen() return value to ssize_t to match write() return type.
    - Use underscore-prefixed system preprocessor symbols instead of namespace
      polluting ones (such as “linux”, “OPENBSD” or “hpux”).
    - Handle _POSIX_PRIORITY_SCHEDULING being defined to -1 or 0 in
      start-stop-daemon. This affects Mac OS X.
    - On FreeBSD return STATUS_UNKNOWN instead of false in start-stop-daemon
      do_procinit().
    - Port start-stop-daemon process handling to Mac OS X.
      Based on a patch by Mo McRoberts <email address hidden>.
    - Port start-stop-daemon process handling to AIX.
    - Fix lookup by name on update-alternatives --config. The code was wrong
      and not working at least on Mac OS X, making the test suite to fail.
    - Only use gzip --rsyncable in Dpkg::Compression on Debian and hopefully
      derivatives, by using perl's $Config{cf_by} variable to key on. The
      Debian-specific --rsyncable option should have never been accepted for
      use in dpkg to begin with.
    - Use our own dpkg_ar_hdr struct instead of relying on the system
      ar_hdr struct, as the ar format is not standardized and does vary
      across systems, for example on AIX.
    - Add <sys/sysmacros.h> on AIX for major() and minor().
    - Add missing <errno.h> in libcompat.
    - Include libcompat getopt module when we need getopt_long.
    - Disable gettext support in libcompat getopt module. We do not carry
      translations for this module, and it makes it pull libintl for programs
      that might not use it otherwise.
  * Perl modules:
    - Obsolete Source-Version substvar in Dpkg::Substvars by emitting errors.
    - Rework keyring hooks in Dpkg::Vendor. Deprecate the keyrings hook, and
      add package-keyrings, archive-keyrings and archive-keyrings-historic
      hooks. Prompted by Johannes Schauer <email address hidden>.
    - Make the Dpkg::Substavars parse() method return the number of substvars
      parsed.
    - Add new set_field_substvars() method to Dpkg::Substvars.
    - Fix reproducible source package support in Dpkg::Source::Archive, by
      sorting the tar contents with --sort=name.
    - Prefix private Dpkg::Source::Package::* functions with _.
    - Defer filehandle closures in Dpkg::IPC::spawn() to avoid double-close.
      Closes: #839905, #840293
    - Always map the build type to the shortest string form in
      Dpkg::Build::Type::get_build_options_from_type().
    - Change Dpkg::Compression::FileHandle to inherit directly from IO::File
      instead of FileHandle.
    - Add new Dpkg::PROGTAR variable to store GNU tar command name.
    - Add new Dpkg::PROGMAKE variable to store GNU make command name.
    - Add new CTRL_FILE_BUILDINFO type to Dpkg::Control.
    - Add new .buildinfo fields to Dpkg::Control::Fields.
    - Add new builtin-system-build-paths Dpkg::Vendor hook.
    - Cope gracefully with changelogs missing a timestamp trailer.
      Based on a patch by Ian Jackson <email address hidden>.
      Regression introduced in dpkg 1.18.8. Closes: #843248
  * Packaging:
    - Add liblocale-gettext-perl to libdpkg-perl Recommends.
    - Wrap and document dependency relationships.
    - Remove obsolete dependency relationships, since Debian oldstable.
    - Remove update-alternatives, dpkg-divert and dpkg-statoverride
      compatibility symlinks, again.
    - Use perl:Depends via dh_perl instead of a hardcoded perl in Depends.
    - Add perl:Depends to dpkg-dev Depends.
    - Remove unused dh_strip from binary_indep target.
    - Remove ancient upgrade code from maintainer scripts (before 1.15.x).
    - Stop compressing the dpkg.deb package with gzip.
    - Move dpkg to be the first binary package stanza in debian/control, as
      debhelper assigns special meaning by considering it the main package.
    - Set MAKEFLAGS to -jN from parallel=N in DEB_BUILD_OPTIONS.
  * Documentation:
    - Update custom changelog parser API support status in README.api.
    - Fix typos in docs and man pages. Thanks to Jakub Wilk <email address hidden>
      Closes: #834584
    - Fix formatting in SOURCE_DATE_EPOCH description in dpkg-deb(5).
    - Improve dpkg-deb --build arguments documentation in dpkg-deb(1).
      Prompted by Johannes Schauer <email address hidden>.
    - Document the .changes filename that dpkg-buildpackage generates in
      dpkg-buildpackage(1). Prompted by Johannes Schauer <email address hidden>.
    - Add basic maintainer script man pages: deb-postinst(5), deb-postrm(5),
      deb-preinst(5) and deb-prerm(5).
    - Add new deb-src-files(5) man page.
      Prompted by Johannes Schauer <email address hidden>.
    - Add man page references to other binary control files in dpkg(1).
    - Add version when "new" substvars were introduced in deb-substvars(5).
    - Switch deb-triggers(5) types into a proper list.
    - Itemize --log format entries in dpkg(1).
    - Turn the update-alternatives(1) --query example item into a sub-section.
    - Turn the Multi-Arch values into a list in deb-control(5).
    - Improve user-defined field export marker documentation in
      deb-src-control(5); clarify that X can be followed by zero or more
      (instead of one or more) letters and turn the items into a proper list.
    - Generate the man pages at build time. This makes it possible to process
      them and update several variable strings such as system and package
      pathnames, the release date and the dpkg suite version. And makes it
      possible to use UTF-8 in the source and convert to the more conservative
      groff escape sequences on the output.
    - Switch from groff escape sequences to UTF-8 in man pages sources.
    - Disable hyphenation in man pages globally, because it performs very
      poorly on many technical terms.
    - Append the German man pages addendum at the end of the translation,
      instead of assuming that every page has the SEE ALSO section.
    - Explicitly mention that Dpkg::Checksums::add_from_file() is used to
      verify digests too. Prompted by Johannes Schauer <email address hidden>.
    - Document the behavior for consecutive calls to Dpkg perl module parse()
      methods. Prompted by Johannes Schauer <email address hidden>.
    - Document obsolete functions in Dpkg::Conf.
  * Test suite:
    - Make test main function a TEST_ENTRY macro. This avoids confusing
      coverage programs, as the file that actually contains the main function
      is the test itself.
    - Rename test suite commands to be prefixed with «c-» instead of «t-».
    - Add new dpkg-source functional tests.
    - Add new dpkg-buildpackage functional tests.
    - Add an initial functional test suite for dpkg-deb and dpkg-split.
    - Skip the involved tests if IO::String is missing.
    - Add new unit test for libdpkg error handling.
    - Delete MAKEFLAGS environment variable when testing make invocations.
    - Pass -q to grep command to suppress matched output in pod-coverage.t.
    - Ignore POD coverage for partially private modules.
  * Build system:
    - Add support for profiling perl modules.
    - Clean up compiler and linker automatic flag usage in configure.
    - Fix the __progname check to avoid the optimizer discarding the symbol.
    - Fix M4sh/Autoconf coding style. Add a new section to coding-style.txt
      describing M4sh/Autoconf.
    - Disable C++ exceptions for dselect.
    - Fix typo in SE Linux library detection code, only affecting static
      mode (not used in Debian). Regression introduced in dpkg 1.18.8.
    - Change --with-* option logic to default to check.
    - Disable -Wtautological-constant-out-of-range-compare (for clang).
    - Check the availability of -W<warning> variant instead of -Wno-<warning>.
      As at least gcc and clang do not warn on -Wno-* warning flags, only
      when some unrelated warning needs to be emitted.
    - Bump po4a version to 0.43 (we are using --porefs wrap option).
    - Add support for running the test suite in parallel.
    - Specify exec argument for TAP::Harness to gracefully handle non-perl
      executables with older versions of the module.
    - Require libselinux 2.0.99 for baseline API, remove static linking
      support, use pkg-config unconditionally, and perform refinement checks
      only if available.
    - Check for the required minimal perl version.
    - Use builddir instead of CURDIR in man Makefile.am.
    - Use cp with -R instead of -r (the former is more portable and not
      marked as deprecated by POSIX).
    - Print an actual newline instead of a literal \n in lcov output.
    - Do not honor DPKG_DATADIR on the installed Dpkg module.
    - Pass --as-needed to the linker for dselect to avoid libstdc++ dependency.
      Which makes of dselect the only front-end not pulling the C++ run-time.
