merge 'after squeeze release'-stuff
[ David Kalnischkies ] * apt-pkg/depcache.cc: - add SetCandidateRelease() to set a candidate version and the candidates of dependencies if needed to a specified release (Closes: #572709) * cmdline/apt-get.cc: - if --print-uris is used don't setup downloader as we don't need progress, lock nor the directories it would create otherwise - show dependencies of essential packages which are going to remove only if they cause the remove of this essential (Closes: #601961) - keep not installed garbage packages uninstalled instead of showing in the autoremove section and installing those (Closes: #604222) - change pkg/release behavior to use the new SetCandidateRelease so installing packages from experimental or backports is easier - really do not show packages in the extra section if they were requested on the commandline, e.g. with a modifier (Closes: #184730) * debian/control: - add Vcs-Browser now that loggerhead works again (Closes: #511168) - depend on debhelper 7 to raise compat level - depend on dpkg-dev (>= 1.15.8) to have c++ symbol mangling * apt-pkg/contrib/fileutl.cc: - add a RealFileExists method and check that your configuration files are real files to avoid endless loops if not (Closes: #604401) - ignore non-regular files in GetListOfFilesInDir (Closes: #594694) * apt-pkg/contrib/weakptr.h: - include stddefs.h to fix compile error (undefined NULL) with gcc-4.6 * methods/https.cc: - fix CURLOPT_SSL_VERIFYHOST by really passing 2 to it if enabled * deb/dpkgpm.cc: - fix popen/fclose mismatch reported by cppcheck. Thanks to Petter Reinholdtsen for report and patch! (Closes: #607803) * doc/apt.conf.5.xml: - fix multipl{y,e} spelling error reported by Jakub Wilk (Closes: #607636) * apt-inst/contrib/extracttar.cc: - let apt-utils work with encoded tar headers if uid/gid are large. Thanks to Nobuhiro Hayashi for the patch! (Closes: #330162) * apt-pkg/cacheiterator.h: - do not segfault if cache is not build (Closes: #254770) * doc/apt-get.8.xml: - remove duplicated mentioning of --install-recommends * doc/sources.list.5.xml: - remove obsolete references to non-us (Closes: #594495) * debian/rules: - use -- instead of deprecated -u for dh_gencontrol - remove shlibs.local creation and usage - show differences in the symbol files, but never fail * pre-build.sh: - remove as it is not needed for a working 'bzr bd' * debian/{apt,apt-utils}.symbols: - ship experimental unmangled c++ symbol files * methods/rred.cc: - operate optional on gzip compressed pdiffs * apt-pkg/acquire-item.cc: - don't uncompress downloaded pdiff files before feeding it to rred - try downloading clearsigned InRelease before trying Release.gpg - change the internal handling of Extensions in pkgAcqIndex - add a special uncompressed compression type to prefer those files - download and use i18n/Index to choose which Translations to download * cmdline/apt-key: - don't set trustdb-name as non-root so 'list' and 'finger' can be used without being root (Closes: #393005, #592107) * apt-pkg/deb/deblistparser.cc: - rewrite LoadReleaseInfo to cope with clearsigned Releasefiles * ftparchive/writer.cc: - add config option to search for more patterns in release command - include Index files by default in the Release file * methods/{gzip,bzip}.cc: - print a good error message if FileSize() is zero * apt-pkg/aptconfiguration.cc: - remove the inbuilt Translation files whitelist
