* don't loop on pinning pkgs from absolute debs by regexDavid Kalnischkies2016-08-291-1/+5
| | | | | | | | | | | | | | | | | | | | | An absolute filename for a *.deb file starts with a /. A package with the name of the file is inserted in the cache which is provided by the "real" package for internal reasons. The pinning code detects a regex based wildcard by having the regex start with /. That is no problem as a / can not be included in a package name… expect that our virtual filename package can and does. We fix this two ways actually: First, a regex is only being considered a regex if it also ends with / (we don't support flags). That stops our problem with the virtual filename packages already, but to be sure we also do not enter the loop if matcher and package name are equal. It has to be noted that the creation of pins for virtual packages like the here effected filename packages is pointless as only versions can be pinned, but checking that a package is really purely virtual is too costly compared to just creating an unused pin.

* randomize acquire order for same type index filesDavid Kalnischkies2016-08-292-3/+23
| | | | | | | | | | | | | | | Without randomizing the order in which we download the index files we leak needlessly information to the mirrors of which architecture is native or foreign on this system. More importantly, we leak the order in which description translations will be used which in most cases will e.g. have the native tongue first. Note that the leak effect in practice is limited as apt detects if a file it wants to download is already available in the latest version from a previous download and does not query the server in such cases. Combined with the fact that Translation files are usually updated infrequently and not all at the same time, so a mirror can never be sure if it got asked about all files the user wants.

| * test: Assert multi-arch in the chrootJulian Andres Klode2016-08-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The host system might not have a dpkg installed, which makes dpkg fail with: dpkg not recorded as installed, cannot check for multi-arch support! That's entirely useless of course. We want to know if dpkg could support multi-arch in our chroot, so we pseudo-install dpkg into the chroot and pretend it's version is one version higher than the minimum dpkg version, so dpkg --assert-multi-arch works on recent dpkgs.

| * test: Use printf "%b\n" instead of echo for strings with '\'Julian Andres Klode2016-08-262-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Use of echo with special characters is not portable. On a normal POSIX system, the behavior with backslash escaped strings is implementation-defined. On an XSI-conformant system, they must be interpreted. A way out is the printf command - printf "%b" specifies that the following argument is to be printed with backslash escapes interpreted. Gbp-Dch: ignore

| | | | | | | | | | | | | | Especially on non-Debian platforms, dpkg might not list itself on the host system, and thus dpkg --assert-multi-arch fails. Gbp-Dch: ignore

| * test: Explicitly pass --admindir=var/lib/dpkg to dpkgJulian Andres Klode2016-08-261-0/+2

| | | | | | | | | | | | | | This allows other vendors to use different paths, or to build your own APT in /opt for testing. Note that this uses + 1 in some places, as the paths we receive are absolute, but we need to strip of the initial /.
| * Add missing includes and external definitionsJulian Andres Klode2016-08-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several modules use std::array without including the array header. Bad modules. Some modules use STDOUT_FILENO and friends, or close() without including unistd.h, where they are defined. One module also uses WIFEXITED() without including sys/wait.h. Finally, environ is not specified to be defined in unistd.h. We are required to define it ourselves according to POSIX, so let's do that.
* | treat .ddeb files like .deb, especially for dpkgDavid Kalnischkies2016-08-251-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ubuntu uses *.ddeb files for their debug packages, but the interface we are using since f495992428a396e0f98886c9a761a804aa161c68 to talk to dpkg isn't supporting *.ddeb files. This used to work previously as apt itself isn't caring about the filenames at all and if they are explicitly mentioned dpkg will accept all, too. It might or might not be a good idea to patch dpkg, too, but regardless of it happening, we don't want to couple us to closely to dpkg for this minor feature but testing for this at runtime as it would delay shipping the fix for the too long commandlines further. It is also questionable if it is really a good idea to allow any file extension to be used here (like .foobar in the testcase), but we used to and we tend to avoid breaking existing usecases if we can help it. As a bonus, this also allows the installation of ddeb files directly from the commandline as you can with deb files already. We continue to ignore udeb through as the user-mistake to useful ratio is too high. LP: #1616909
* | show apt-key warnings in apt updateDavid Kalnischkies2016-08-251-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 105503b4b470c124bc0c271bd8a50e25ecbe9133 we got a warning implemented for unreadable files which greatly improves the behavior of apt update already as everything will work as long as we don't need the keys included in these files. The behavior if they are needed is still strange through as update will fail claiming missing keys and a manual test (which the user will likely perform as root) will be successful. Passing the new warning generated by apt-key through to apt is a bit strange from an interface point of view, but basically duplicating the warning code in multiple places doesn't feel right either. That means we have no translation for the message through as apt-key has no i18n yet. It also means that if the user has a bunch of sources each of them will generate a warning for each unreadable file which could result in quite a few duplicated warnings, but "too many" is better than none.

* | apt-key: warn instead of fail on unreadable keyringsDavid Kalnischkies2016-08-251-0/+24
| | | | | | | | | | | | | | | | | | | | | | apt-key has inconsistent behaviour if it can't read a keyring file: Commands like 'list' skipped silently over such keyrings while 'verify' failed hard resulting in apt to report cconfusing gpg errors (#834973). As a first step we teach apt-key to be more consistent here skipping in all commands over unreadable keyrings, but issuing a warning in the process, which is as usual for apt commands displayed at the end of the run.
* | do not restore selections for already purged packagesDavid Kalnischkies2016-08-242-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In most cases apt was already skipping the (re)setting of packages as to be removed/purged if dpkg had told us that it already did, but we haven't dealt with it in the most obvious of the cases: Selections set for packages we touched in this operation which either restores selections even dpkg would have overridden or e.g. tries to restore a purge selection for a package which was just purged – does not happen with apt itself as it isn't using selections in this way, but higher frontends like aptitude do. The result in the later case is a warning printed by dpkg that we try to set selections for an unknown package, which is harmless per se, but can be confusing for users and we really shouldn't cause warnings in dpkg if we can help it.

* | do fail on weakhash/loop earlier in acquireDavid Kalnischkies2016-08-245-4/+12
|/ | | | | | | | | | | | | | | | | The bugreport shows a segfault caused by the code not doing the correct magical dance to remove an item from inside a queue in all cases. We could try hard to fix this, but it is actually better and also easier to perform these checks (which cause instant failure) earlier so that they haven't entered queue(s) yet, which in return makes cleanup trivial. The result is that we actually end up failing "too early" as if we wouldn't be careful download errors would be logged before that process was even started. Not a problem for the acquire system, but likely to confuse users and programs alike if they see the download process producing errors before apt was technically allowed to do an acquire (it didn't, so no violation, but it looks like it to the untrained eye). Closes: 835195
* do dpkg --configure before --remove/--purge --pendingDavid Kalnischkies2016-08-232-0/+45
| | | | | | | | | | | | | | | | | | | Commit 7ec343309b7bc6001b465c870609b3c570026149 got us most of the way, but the last mile was botched by having the pending calls in the wrong order as this way we potentially 'force' dpkg to remove/purge a package it doesn't want to as another package still depends on it and the replacement isn't fully installed yet. So what we do now is a configure before remove and purge (all with --no-triggers) and finishing off with another configure pending call to take care of the triggers. Note that in the bugreport example our current planner is forcing dpkg to remove the package earlier via --force-depends which we could do for the pending calls as well and could be used as a workaround, but we want to do less forcing eventually. Closes: 835094
* methods: read config in most to least specific orderDavid Kalnischkies2016-08-171-2/+3
| | | | | | | | | | | | The implementation of the generic config fallback did the fallback in the wrong order so that the least specific option wasn't the last value picked but in fact the first one… doh! So in the bugreports case http -> https -> http::<hostname> -> https::<hostname> while it should have been the reverse as before.

* add --with-source option and Packages/Sources supportDavid Kalnischkies2016-08-172-1/+36
| | | | | | | | | | | | | We support "./foobar.deb" as a way to install a deb file directly. Recently .changes files were added. This highlights a problem as you can't add the changes file without also trying to install all of them. Now, it could also be handy to add entire Packages/Sources files to perhaps get a bunch of packages in without installing them all implicitly. This commit introduces --with-source which allows to add *.deb, *.changes, *.dsc, source-dirs, Packages & Sources files (the later can also be compressed) without also installing them.
* allow spaces in fingerprints for 'apt-key del'David Kalnischkies2016-08-171-0/+8
| | | | | | Fingerprints tend to be displayed in space-separated octet pairs so be nice and allow delete to remove a key based on such a string rather than requiring that the user is deleting all the spaces manually.
* add the gpg-classic variant to the gpgv/gnupg or-groupDavid Kalnischkies2016-08-174-54/+39
| | | | | | We need to support partial upgrades anyhow, so we have to deal with the different versions and your tests try to ensure that we do, so we shouldn't make any explicit higher requirements.
* tests: update self-sigs on our test keysDavid Kalnischkies2016-08-1710-0/+0
| | | | | | | | | | | | | | | | | | gpg upstream committed "gpgv: Tweak default options for extra security." applied on the 1.x and 2.x branches: http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=e32c575e0f3704e7563048eea6d26844bdfc494b This commit includes "[…], but we should validate the key by its self signature for primary key, and back signature for subkey." Our testkeys are old and do not really considered best practices in the last years, so their most recent self-signature is SHA1-only which with this gpg commit and our testcases defaulting to --weak-digest sha1 are refused. So what we do here is just applying some of the recent best practices on top of our testcase keys. Gbp-Dch: Ignore

* support compression and by-hash for .diff/Index filesDavid Kalnischkies2016-08-171-0/+29
| | | | | | | | | | | In af81ab9030229b4ce6cbe28f0f0831d4896fda01 by-hash got implemented as a special compression type for our usual index files like Packages. Missing in this scheme was the special .diff/Index index file containing the info about individual patches for this index file. Deriving from the index file class directly we inherent the compression handling infrastructure and in this way also by-hash nearly for free. Closes: #824926
* retry without same redirection mirror on 404 errorsDavid Kalnischkies2016-08-171-4/+20
| | | | | | | | If 9b8034a9fd40b4d05075fda719e61f6eb4c45678 serves the Release files from a partial mirror we will end up getting 404 for some of the indexes. Instead of giving up, we will instead ignore our same redirection mirror constrain and ask the redirection service as a potential hashsum mismatch is better than keeping the certain 404 error.
* don't sent Range requests if we know its not acceptedDavid Kalnischkies2016-08-165-5/+17
| | | | | | If the server told us in a previous request that it isn't supporting Ranges with bytes via an Accept-Ranges header missing bytes, we don't try to formulate requests using Ranges.
* http(s): allow empty values for header fieldsDavid Kalnischkies2016-08-132-0/+4
| | | | | | | | | | | | It seems completely pointless from a server-POV to sent empty header fields, so most of them don't do it (simply proven by this limitation existing since day one) – but it is technically allowed by the RFC as the surounding whitespaces are optional and Github seems to like sending "X-Geo-Block-List:\r\n" since recently (bug reports in other http clients indicate July) at least sometimes as the reporter claims to have seen it on https only even through it can happen with both.

* ensure a good clock() value for usage and testsDavid Kalnischkies2016-08-121-1/+9
| | | | | | | | | | | We use clock() as a very cheap way of getting a "random" value, but the manpage warns that this could return -1, so we should be dealing with this. Additionally, e.g. on hurd-i386 the value increases only slowly – to slow for our fast running tests for randomness hence producing the same range in both samples, so we introduce a simple busy-wait loop (as clock is counting processor time used by the program) in the test which delays the second sample just enough making our randomness a bit more predictable.
* don't perform int<float in progress bar drawingDavid Kalnischkies2016-08-121-1/+6
| | | | | | | | Comparing floating numbers is always fun and in this instance a 9 < 9.0 is "somehow" true on hurd-i386 letting the tests fail by reporting that too much progress achieved. A bit mysterious, but with some rework we can use code which avoids dealing with the floats in this way entirely and make our testcases happy.
* tests: copy 01autoremove from the right placeDavid Kalnischkies2016-08-111-2/+2
| | | | | | | | | | | | With cmake using BUILDDIRECTORY at this place is not only as wrong as it was before, but it might not even work always copying the system provided one which might or might not be current and hence fails tests needing it to be current like ./test-apt-move-and-forget-manual-sections We don't want to always use the one from the source directory through either like in autopkgtests.

| * disable explicit configuration of all packages at the endDavid Kalnischkies2016-08-1013-75/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With b4450f1dd6bca537e60406b2383ab154a3e1485f we dropped what we calculated here later on and now that we don't need it in the meantime either we can just skip the busy work by default and expect dpkg to do the right thing dropping also our little "last explicit configures" removal trick introduced in b4450f1dd6bca537e60406b2383ab154a3e1485f. This enables the last of a bunch of previously experimental options, some of them existing still, but are very special and hence not really worth documenting anymore (especially as it would need to be rewritten now entirely) which is why the documentation is nearly completely dropped. The order of configuration stanzas in the simulation code changes slightly as it isn't concerning itself with finding the 'right' order, but any order is valid anyhow as long as the entire set happens in the same call.
| * try to avoid removal of crossgraded packagesDavid Kalnischkies2016-08-101-0/+49
| | | | | | | | | | | | | | | | The user has to approve the removal of a crossgraded package as it might be needed to remove it (temporarily) in the process, but in most cases we can happily avoid it and let dpkg unpack over it skipping the remove. This has some effects on progress reporting and how deal with selections through which makes this a tiny bit complicated.
| * don't purge directly, but remove and do purge at the endDavid Kalnischkies2016-08-101-2/+2
| | | | | | | | | | | | | | | | | | | | If we want a package to be purged from the system tell dpkg in the ordering (if it has to touch it explicitly) to remove it and cover the purging of the config files at the end with a --purge --pending call. That should help packages move conffiles around between packages correctly even if the user is purging packages directly in big actions like dist-upgrades involving many packages.
| * select remove/purge packages early on for dpkgDavid Kalnischkies2016-08-101-1/+1
| | | | | | | | | | | | | | Telling dpkg early on that we are going to remove these packages later helps it with auto-deconfiguration decisions and its another area where a planner can ignore the nitty gritty details and let dpkg decide the course of action if there are no special requirements.
| * save and restore selection states before/after calling dpkgDavid Kalnischkies2016-08-101-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | dpkg decides certain things on its own based on selections and especially if we want to call --pending on purge/remove actions, we need to ensure a clean slate or otherwise we surprise the user by removing packages we weren't allowed to remove by the user in this run (the selection might be an overarching plan for the not-yet "future"). Ideally dpkg would have some kind of temporal selection interface for this case, but it hasn't, so we make it temporal with the risk of loosing state if we don't manage to restore them.
