--- Begin Message ---Package: dpkg Version: 1.13.22 If A -Conflicts-> B, then dpkg correctly refuses to unpack A if B is installed and to unpack B if A is installed. Furthermore, dpkg correctly refuses to unpack A even if B is merely unpacked or half-installed etc. However, if A is unpacked or half-installed, the conflict is not checked and it is possible to unpack B. This is a mistake. Between two packages, Conflicts is a relationship with symmetrical effects (in the absence of Replaces). I think it might also be possible to remove the predependencies of merely-unpacked packages, but I haven't tested this. The cause lies in depcon.c, in depisok: /* The dependency is always OK if we're trying to remove the depend*ing* * package. */ switch (dep->up->clientdata->istobe) { case itb_remove: case itb_deconfigure: return 1; case itb_normal: /* Only `installed' packages can be make dependency problems */ switch (dep->up->status) { case stat_installed: break; case stat_notinstalled: case stat_configfiles: case stat_halfinstalled: case stat_halfconfigured: case stat_unpacked: return 1; default: internerr("unknown status depending"); } It is not true that only `installed' packages can cause dependency problems. Both Conflicts and Pre-Depends, and soon Breaks, can cause problem even if the `source' package for the dependency is not completely installed. I _think_ simply saying something like this: case stat_halfinstalled: case stat_halfconfigured: case stat_unpacked: if (dep->type == dep_conflicts || dep->type == dep_predepends || dep->type == dep_breaks) break; /* fall through */ case stat_notinstalled: case stat_configfiles: return 1; ought to fix it but I haven't tested this. Ian.

[ Guillem Jover ] * Cast c_isbits() c argument to an unsigned char when indexing the array. This fixes build failures on armel, armhf, ppc64el and s390x. * Do not allow pathnames with embedded newlines in dpkg-deb and dpkg. Closes: #720761 * Fix setting the SE Linux context when a file has a statoverride. Closes: #786435 * Set the SE Linux file context even when the file mode has no file type. * Make dpkg-buildpackage -j override any parallel option specified in DEB_BUILD_OPTIONS. Regression introduced in dpkg 1.14.15. * Honor Pre-Depends, Conflicts and Breaks for packages in unpacked and half states. Thanks to Ian Jackson <[email protected]>. Closes: #377860 * Fix build failure on FreeBSD by actually using libmd if available. * Sort dpkg-scanpackages output by package name and version. Thanks to Maximilian Schwerin <[email protected]>. * Sort dpkg-scansources output by package name and version. Thanks to Maximilian Schwerin <[email protected]>. * Set the correct default compression value in dpkg-deb for control.tar.gz member. This meant using compression level 1 when using the zlib shared library to compress the control.tar member, and always failing when using the gzip command. Regression introduced in dpkg 1.17.6. Closes: #786654 * Use the generated template file instead of the original one when looking for changes in dpkg-gensymbols. There's too much information not being preserved in the symbols files to be able to regenerate templates for them. Closes: #785937, #786840 * Perl modules: - Add missing strict and warnings pragmas for submodules. - Use non-destructive substitutions inside map. - Use the state keyword to simplify the code. - Do not replace #PACKAGE# in template mode in Dpkg::Shlibs::SymbolFile. * Documentation: - Update current default source compressor from gzip to xz. - Remove spurious ‘=’ from parallel DEB_BUILD_OPTIONS without arguments in dpkg-buildpackage(1). . [ Updated programs translations ] * German (Sven Joachim). * Simplified Chinese (Zhou Mo). Closes: #786377 . [ Updated manpages translations ] * German (Helge Kreutzmann). . [ Updated dselect translations ] * German (Sven Joachim).
