This bug was fixed in the package dpkg - 1.16.1ubuntu1
---------------
dpkg (1.16.1ubuntu1) precise; urgency=low
* Resynchronise with Debian. Remaining changes:
- Merge from git://git.debian.org/users/hertzog/dpkg.git
pu/multiarch/full for multiarch support.
- On upgrade from 1.16.0~ubuntu[1-3], if /var/lib/dpkg/info/$arch is a
directory, migrate the contents to var/lib/dpkg/info; and handle the
reverse on downgrade. This does not handle metadata for packages of
foreign architectures.
- 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. This is useful for tools
that hide the dpkg terminal by default and use apport for bug
reporting with the untranslated error message.
- Add /etc/dpkg/dpkg.cfg.d/multiarch as a conffile on amd64, so that
users are guaranteed to always have it after upgrade even if they
don't use update-manager for the upgrade itself.
* Continue exporting compiler flags in dpkg-buildpackage, since we do not
want to regress hardening support in Ubuntu 12.04 LTS. We will revisit
this for Ubuntu 12.10.
dpkg (1.16.1) unstable; urgency=low
[ Raphaël Hertzog ]
* Dpkg::Deps: Implement new "reset" method and bump module version to 1.01
due to this.
* Improved description of --search in dpkg-query(1). Closes: #621066
Thanks to Lars Buitinck <larsmans at gmail.com> for the patch.
* Let update-alternatives fsync() its administrative files before
moving them in place to avoid empty files with some filesystems.
LP: #344019
* Tighten the regexp used by dpkg-source to ignore the .pc directory of
quilt. Thanks to Mike Hommey for noticing the problem.
* Change behaviour of dpkg-source's --extend-diff-ignore to also
extend the current diff-ignore if it has already been set.
* Fix dependency checking code to consider a dependency on a virtual
package provided by a package in triggers-pending status as satisfied.
* Do not fail when encountering a pre-dependency in triggers-awaited state,
instead process the awaited triggers. Closes: #526774
* "any" no longer hides "all" in the Architecture field of a .dsc.
* Fix dpkg --remove to really remove the triggers from the various
internal files in /var/lib/dpkg/info/triggers/. Closes: #525160
* Avoid a perl warning in dpkg-gensymbols when no symbols file has been
generated (because it would have been empty). Closes: #626684
* Re-enable the Package-List field but drop the Architecture column since we
have no clear use case yet. It can always be added later on.
Also drop the source line since it duplicates other fields.
Closes: #619131
* Add the extraction part of Dpkg::Source::Package to the supported API.
Useful to extract source packages without having to depend on dpkg-source
(and hence dpkg-dev).
* Add the Dpkg::Vendor module to the supported API. Useful for lintian
when dpkg-dev is absent.
* Check presence of required parameters in dpkg-vendor. Closes: #628726
Thanks to Niels Thykier <niels at thykier.net> for the patch.
* Avoid a Perl warning in dpkg-buildflags when HOME is not set.
Closes: #635467
* dpkg-source can now also use debian/source/local-patch-header (that is not
included in the generated source package) instead of
debian/source/patch-header. Closes: #629582
* Changed dpkg-source --after-build to automatically unapply patches that it
has applied during --before-build.
* Fix two possible causes for the assertion failure "pigp->trigpend_head".
LP: #798793, #424358 Closes: #560251
* Use "special" instead of "particular" to qualify the "3.0 (custom)" format
in dpkg-source(1). Closes: #631435
* Add some supplementary checks to ensure debian/control has the required
fields. Closes: #631439
* dpkg-gensymbols(1): document syntax of comments. Closes: #630996
* Allow empty lines in symbols files to better delimit multiple libraries.
Thanks to Cyril Brulebois <kibi at debian.org> for the patch.
* dpkg: if "prerm upgrade" fails when downgrading, do not try to run
"prerm failed-upgrade" with the prerm of the oldest prerm, it can't work
around a bug of a newer prerm anyway.
* dpkg: support new "interest-noawait" and "activate-noawait" trigger
directives.
* dpkg-buildflags(1): make it clear that DEB_*_(SET|APPEND) environment
variables are meant for users and should not be used by packages.
* update-alternatives: do not allow to reuse a slave link in another
slave alternative. Closes: #631547
* Improve dpkg-source's logic to identify ignored files. Closes: #632168
* Fix a small typo in dpkg-source(1). Closes: #632937
* Reword the description of dpkg-source --before-build and --after-build
to be clearer. Closes: #608260
* dpkg-buildpackage no longer exports the compiler flags. Closes: #560070
Packages must directly call dpkg-buildflags to retrieve them.
* dpkg-buildflags supports a prepend command to modify the build
flags. Particularly useful for package maintainers who don't want
their supplementary flags to take precedence over user submitted
flags.
* Add new --dump action to dpkg-buildflags and make it the default action.
Closes: #603435
* dpkg-mergechangelogs now checks the return value of the close() call.
Thanks to Niels Thykier <niels at thykier.net> for the patch. Closes: #633539
* Similar changes to dpkg-shlibdeps and dpkg-gencontrol, also by Niels.
* Fix update-alternatives to not remove a real file when dropping a
symlink for a slave that's not provided by the new current choice.
Closes: #633627
* Improve dpkg-source's error message complaining about the lack
of the upstream tarball. Closes: #634510
* Add some common makefile snippets for use in rules files in
/usr/share/dpkg/: default.mk, architecture.mk, buildflags.mk, pkg-info.mk,
vendor.mk Closes: #606839
* Fix the dpkg-divert test-suite to also skip test that would fail if run
under root. Closes: #634961
* Change merge conflict separators created by dpkg-mergechangelogs to match
the usual norm of being composed of 7 characters. LP: #815700
* With source format 2.0 and 3.0 (quilt), dpkg-source now fails by default
when upstream changes have not been recorded in a quilt patch. The new
--commit operation can be used to properly record the changes before-hand.
LP: #797839
And it fails before installing the automatic patch in debian/patches/
Closes: #615899
* dpkg-buildflags now supports "--export=configure" to output compilation
flags on a single line with double quotes as delimiter of the various
values. It also uses DEB_<flag>_MAINT_<op> to let the maintainer
extend the build flags to use. Last but not least, it can now also strip
options from the returned build flags.
* Fix possible segfault of dpkg in findbreakcycle(). LP: #733414
* dpkg-source now properly cleans up the temporary tarball generated for
native formats in case of unexpected interruption. Closes: #631494
* Fix simplification logic of union dependencies. Closes: #637564
* Fix dpkg's handling of a hardlink pointing to a conffile. Closes: #638291
* Add example of extend-diff-ignore's usage in dpkg-source(1).
Closes: #640198
* dpkg-buildflags now returns hardening flags by default. Closes: #489771
They can be individually enabled/disabled via DEB_BUILD_MAINT_OPTIONS,
see dpkg-buildflags(1). Thanks to Kees Cook for his help.
[ Guillem Jover ]
* Install deb-src-control(5) man pages in dpkg-dev. Closes: #620520
* Add ‘.gitmodules’ to the default dpkg-source ignore lists. Closes: #620490
* Document in dpkg-query(1) man page that on --listfiles each list of
files per package name is separated by a blank line. Same goes for
--status and --print-avail.
* Use execvp(3) unconditionally in command_exec(). Making the call always
fallback to use the system shell in case of error, such as with empty
maintainer scripts. Thanks to Jonathan Nieder <jrnieder at gmail.com>.
Closes: #622094
* Improve deb-split(5) format description by splitting debian-split
member contents into a list.
* Switch to debhelper compatibility level 7.
- Use dh_prep instead of deprecated “dh_clean -k”.
* Bump Standards-Version to 3.9.2 (no changes needed).
* Generate filenames following current conventions on “dpkg-split --join”,
by including the architecture in the debian-split member of a split
package and using underscores to separate filename parts.
* Support conffiles with spaces when diffing them. Closes: #147583
* Allow installing packages with bogus versions with new
--force-bad-version.
* Do not fail when unpacking a diverted hardlink. Closes: #245322
Based on a patch by Christopher Baines <cbaines8 at gmail.com>.
* Document in dpkg-deb(1) that --fsys-tarfile will always process the
input archive sequentially. Closes: #616609
* Remove long non-functional --new and --old dpkg-deb option handling
from dpkg which were being treated as dpkg commands.
* Remove reference to --nocheck dpkg-deb option from dpkg man page as
the latter does not pass it to the former.
* Clarify the current dpkg behaviour when running the dpkg-deb and
dpkg-query back-ends, of not passing through back-end specific options
when running them from dpkg. Closes: #610940
* Use “unselected” as an adjective in dpkg output messages instead of
“deselected”. Closes: #231089
* Clarify exit status in dpkg-split and start-stop-daemon --help output.
* Clarify “EXIT STATUS” section in man pages by using a table.
* Add a --status command to start-stop-daemon returning LSB Init Script
status action exit codes.
* Add start-stop-daemon process name kernel limits for Solaris, NetBSD,
OpenBSD, FreeBSD and Darwin.
* On package removal, keep only directories actually containing conffiles,
and not directories just matching the substring in the conffile or the
directory itself. Thanks to Ondřej Surý <ondrej at debian.org>.
* On purge correctly remove symlinks acting as directories, when they are
not being used by any other package's files.
* Do not lose track of parent directories on removal so that they can
be properly cleaned up on purge if not used by any other package.
Based on a patch by Ondřej Surý <ondrej at debian.org>. Closes: #454694
* Add ‘.hgsigs’ to the default dpkg-source ignore lists.
Based on a patch by Jakub Wilk <jwilk at debian.org>. Closes: #627462
* Do not allow blank lines in field values. Closes: #308082
* Do not warn on missing architecture on packages in config-files state,
but then make sure the architecture field is usable. Closes: #604241
* Run du with --apparent-size when generating the Installed-Size field in
dpkg-gencontrol to get consistent results independent of build system.
Thanks to Ludovic Brenta <ludovic at ludovic-brenta.org>. Closes: #630533
* Do not fail to unpack shared directories missing on the file system
from packages being replaced by other packages. Closes: #631808
* Do not require programs to define thisname, provide two new functions
to handle the program name (dpkg_set_progname and dpkg_get_progname).
Closes: #631757
* Man pages cleanup:
- Rename “USAGE” dselect(1) section to “ACTIONS” and clarify they can
be performed interactively or from command line.
- Add missing built-in methods to dselect(1).
- Add missing escaping to field dashes in deb-control(5).
- Use dashes instead of underscores for variable text.
- Clarify that several front-end fields are not dselect specific in
dpkg-query(1).
- Use [option...] instead of [options] and friends.
- Use italics or bold instead of surrounding the text with <>.
- Correctly format text with bold and italics.
- Use minus signs and hyphens consistently in man pages.
- Fix reference to /etc/dpkg/dselect.cfg.d instead of dpkg.cfg.d in
dselect(1).
- Add missing optional group|gid --chuid argument in start-stop-daemon(8).
* Refer to Sources and Packages files as part of a repository instead of
as being of exclusive use or owned by APT, which has never been the case.
* Unify somewhat dpkg-maintscript-helper --help output with other commands.
* Add build-indep and build-arch targets as aliases for build in
debian/rules.
* Use the perl interpreter found by configure to call dpkg-architecture.pl
in the m4 DPKG_ARCHITECTURE macro.
* Add new --verbose option to dpkg-deb and change --extract to honour it.
Closes: #293280
* Add new --raw-extract option to dpkg-deb combining --control and
--extract. Closes: #552123
* Defer hardlink renames so that there's never a point were the new
file contents are accessible from the final path before they have
been fsync()ed and cannot be executed causing ETXTBSY when trying
to open the to be installed paths for writing.
Thanks to Jonathan Nieder <jrnieder at gmail.com>. Closes: #635683
* Clarify the default dpkg-deb compression-levels on the man page.
* Clarify dpkg --update-avail usage error message. Closes: #628055
* Change Dpkg::Compression default values depending on the compressor
used, and as such dpkg-source inherits this functionality.
Prompted by Timo Juhani Lindfors <timo.lindfors at iki.fi>.
* Print an actual error or warning message instead of assert()ing on
readlink()/stat() size discrepancies. Closes: #639229
* Update alternative links only if they change. This allows for a
read-only file system and a writable database. Closes: #636700
Based on a patch by Salvatore Bonaccorso <carnil at debian.org>.
* Fix double “error:” string in dpkg missing PATH error output.
Closes: #639997
* Do not warn on strange timestamps when unpacking with dpkg-deb.
Closes: #640298
* Reduce dpkg-trigger binary size by refactoring libdpkg modules so that
it does not end up pulling triglib.
* Reduce dpkg-deb binary size by refectoring libdpkg modules so that it
does not end up pulling triglib.
* Do not fail on --compare-version when generating parse warnings.
Existing packages with invalid versions should not fail on their
maintainer scripts due to that.
* Use the user name (instead of the user id) when setting the supplementary
groups in start-stop-daemon. Closes: #641834
* Use --srcdir and --destdir po4a options, and bump Build-Depends version
to 0.36.4.
[ Updated dpkg translations ]
* German (Sven Joachim). Closes: #620312
* Swedish (Peter Krefting).
* French (Christian Perrier).
[ Updated man page translations ]
* French (Christian Perrier).
* German (Helge Kreutzmann) including improvement by "Flo".
* Swedish (Peter Krefting).
[ Updated scripts translations ]
* French (Christian Perrier, Sylvestre Ledru). Closes: #637096
