2013-08-16allow Pre-Install-Pkgs hooks to get info over an FD != stdinDavid Kalnischkies
This adds ::InfoFD option alongside the ::Version one to request sending the information to the specified FD, by default it is STDIN as it was the case before. The environment variable APT_HOOK_INFO_FD contains the FD the data is on as a confirmation that the APT version used understood the request. Allowing the hook to choose the FD is needed/helpful e.g. for shellscripts which have a hard time accessing FDs above 9 (as >= 10 are usually used internally by them) Closes: #671728
2013-08-15use malloc instead of new[] in pkgTagFileDavid Kalnischkies
We don't need initialized memory for pkgTagFile, but more to the point we can use realloc this way which hides the bloody details of increasing the size of the buffer used. Git-Dch: Ignore
2013-08-15ensure that pkgTagFile isn't writing past Buffer lengthDavid Kalnischkies
In 91c4cc14d3654636edf997d23852f05ad3de4853 I removed the +256 from the pkgTagFile call parsing Release files as I couldn't find a mentioning of a reason for why and it was marked as XXX which suggested that at least someone else was suspicious. It turns out that it is indeed "documented", it just didn't found it at first but the changelog of apt 0.6.6 (29. Dec 2003) mentions: * Restore the ugly hack I removed from indexRecords::Load which set the pkgTagFile buffer size to (file size)+256. This is concealing a bug, but I can't fix it right now. This should fix the segfaults that folks are seeing with 0.6.[45]. The bug it is "hiding" is that if pkgTagFile works with a file which doesn't end in a double newline it will be adding it without checking if the Buffer is big enough to store them. Its also not a good idea to let the End pointer be past the end of our space, even if we don't access the data. Closes: 719629

Release files are basically one big Section, so we might safe some Resize circles by starting with the filesize. Git-Dch: Ignore

2013-08-12use our _error stack to generate openpty errorsDavid Kalnischkies
While we don't want these error messages on our usual stack, we can use our usual infrastructure to generate an error message with all the usual bells like errno and strerror attached. Git-Dch: Ignore
2013-08-12do not try to chown if not run as rootDavid Kalnischkies
If this code is run as non-root we are in a special situation (e.g. in our testcases) where it is obvious that we can't enforce user/group on any file, so skip this code altogether instead of bugging users with an error message – which we also switch to a warning as a failure to open the file is "just" a warning, so the 'wrong' owner shouldn't be that much of an issue. The file is still handled with chmod, so all the security we can enforce is still enforced of course, which also gets a warning if it fails. Git-Dch: Ignore
2013-08-12fix: --print-uris removes authenticationDavid Kalnischkies
The constructors of our (clear)sign-acquire-items move a pre-existent file for error-recovery away, which gets restored or discarded later as the acquire progresses, but --print-uris never really starts the acquire process, so the files aren't restored (as they should). To fix this both get a destructor which checks for signs of acquire doing anything and if it hasn't the file is restored. Note that these virtual destructors theoretically break the API, but only with classes extending the sign-acquire-items and nobody does this, as it would be insane for library users to fiddle with Acquire internals – and these classes are internals. Closes: 719263

2013-08-08use pkgTagFile to parse "header" of Release filesDavid Kalnischkies
The handwritten parsing here was mostly done as we couldn't trust the Release file we got, but nowadays we are sure that the Release file is valid and contains just a single section we want it to include. Beside reducing code it also fixes a bug: Fieldnames in deb822 formatted files are case-insensitive and pkgTagFile does it correctly, but this selfbuilt stuff here didn't.
2013-08-08stop skipping "-----" sections in Release filesDavid Kalnischkies
The file we read will always be a Release file as the clearsign is stripped earlier in this method, so this check is just wasting CPU Its also removing the risk that this could ever be part of a valid section, even if I can't imagine how that should be valid. Git-Dch: Ignore
2013-08-08specific pins below 1000 cause downgradesDavid Kalnischkies
We start your quest by using the version of a package applying to a specific pin, but that version could very well be below the current version, which causes APT to suggest a downgrade even if it is advertised that it never does this below 1000. Its of course questionable what use a specific pin on a package has which has a newer version already installed, but reacting with the suggestion of a downgrade is really not appropriated (even if its kinda likely that this is actually the intend the user has – it could just as well be an outdated pin) and as pinning is complicated enough we should atleast do what is described in the manpage. So we look out for the specific pin and if we haven't seen it at the moment we see the installed version, we ignore the specific pin. Closes: 543966

2013-08-01prefer native arch over higher priority for providersColin Watson
The rational from the buglog: > The problem here is that the Priority field in one of the Packages files > is incorrect due to a mishap with reprepro configuration, […] the > amd64 version is Priority: standard but the arm64 version is Priority: > optional (and has a stray "optional: interpreters" field). > […] > However, Priority is a rather weak property of a package because it's > typically applied via overrides, and it's easy for maintainers of > third-party repositories to misconfigure them so that overrides aren't > applied correctly. It shouldn't be ranked ahead of choosing packages > from the native architecture. In this case, I have no user-mode > emulation for arm64 set up, so choosing m4:arm64 simply won't work. This effectly makes the priority the least interesting data point in chosing a provider, which is in line with the other checks we have already order above priority in the past and also has a certain appeal by the soft irony it provides.

2013-07-25pick up Translation-* even if only compressed availableDavid Kalnischkies
On CD-ROMs Translation-* files are only in compressed form included in the Release file. This used to work while we had no record of Translation-* files in the Release file at all as APT would have just guessed the (compressed) filename and accepted it (unchecked), but now that it checks for the presents of entries and if it finds records it expects the uncompressed to be verifiable. This commit relaxes this requirement again to fix the regression. We are still secure "enough" as we can validate the compressed file we have downloaded, so we don't loose anything by not requiring a hashsum for the uncompressed files to double-check them.

2013-07-16fix if-clause to generate hook-info for 'rc' packagesDavid Kalnischkies
The code incorrectly skips printing of current version information, if the package has no current version (for APT, but for dpkg as it is the case for packages which are removed but not purged) by using an unintended "else if" rather than an "if". Closes: 717006

2013-07-11prevent MarkInstall of unsynced Multi-Arch:same siblingsDavid Kalnischkies
Multi-Arch: same packages can be co-installed, but need to have the same version for all installed packages (aka "siblings"). Otherwise the unsynced versions will fight against each other and the auto-install as wel as the problem resolver will later have to decide between holding the packages or to remove one of the siblings (usually a foreign) taking a bunch of packages (like the entire foreign setup) with them. The idea here is now to be more pro-active: MarkInstall will fail for a package if the siblings aren't synced, so we don't allow a situation in which a resolver has to decide if to hold or to remove-upgrade under the assumption that the remove-upgrade decision is always wrong and doesn't deserve to be explored (expect valid out-of-syncs of course). Thats a pretty bold move to take for a library which is used by different solvers so this check is done in IsInstallOk and can be overridden if front-ends want to.
2013-07-11implement arch+= and arch-= for sources.listDavid Kalnischkies
Default is to acquire all architectures from APT::Architectures which can be changed by arch=, but this isn't very flexible if you want "mostly" the default as you have to hardcode the architectures then, so arch-= and arch+= can be used to add/remove architectures from the default set. On a machine with 'amd64' and 'i386' configured the lines: deb [arch+=armel] http://example.org/debian wheezy rocks deb [arch-=amd64] http://example.org/debian jessie rocks will result in the download of: wheezy Packages for 'amd64', 'i386' and 'armel' jessie Packages for 'i386'
2013-07-11Version 3 for DPkg::Pre-Install-Pkgs with MultiArch infoDavid Kalnischkies
Adds on top of Version 2 to all displayed version numbers the architecture as well as the MultiArch flag for consumption by the hooks. Most of the time the architecture will be the same for both versions displayed, but packages might change from "all" to "any" (or back) between versions so we can't display the architecture for packages. Pseudo-Format for Version 3: <name> <version> <arch> <m-a-flag> <compare> <version> <arch> <m-a-flag> Examples: stuff - - none < 1 amd64 none **CONFIGURE** libsame 1 i386 same < 2 i386 same **CONFIGURE** stuff 2 i386 none > 1 i386 none **CONFIGURE** libsame 2 i386 same > - - none **REMOVE** toolkit 1 all foreign > - - none **REMOVE** Closes: #712116

2013-06-24fix SHA2* cleanups to zero-out the complete contextDavid Kalnischkies
GCC 4.8 is now clever enough to warn about: contrib/sha2_internal.cc: In function ‘char* SHA256_End(SHA256_CTX*, char*)’: contrib/sha2_internal.cc:656:31: warning: argument to ‘sizeof’ in ‘void* memset(void*, int, size_t)’ call is the same expression as the destination; did you mean to dereference it? [-Wsizeof-pointer-memaccess] MEMSET_BZERO(context, sizeof(context)); So fix it as suggested. Its interesting though that the SHA2* calculation as far as we need it works even without zeroing out.
