2017-02-22let {dsc,tar,diff}-only implicitly enable download-onlyDavid Kalnischkies
That was the case already for tar-only and diff-only, but in a more confusing way and without a message while dsc "worked" before resulting in a dpkg-source error shortly after as tar/diff files aren't available… (cherry picked from commit 58ebb3017baf46e33a9bb2c1779d6daede27d108)
2017-02-22don't perform implicit crossgrades involving M-A:sameDavid Kalnischkies
dpkg stumbles over these (#844300) and we haven't dropped 'easier' removes to be implicit and to be scheduled by dpkg by default so far so we shouldn't push the decision in such cases to dpkg either. (cherry picked from commit 53f3fc59f4eb37eea57bbde53fb75f2e15af0378)
2017-02-22improve arch-unqualified dpkg-progress parsingDavid Kalnischkies
Our old idea was to look for the first package which would be "touched" and take this as the package dpkg is talking about, but that is incorrect in complicated situations like a package upgraded to/from multiple M-A:same siblings installed. As we us the progress report to decide what is still needed we have to be reasonabily right about the package dpkg is talking about, so we jump to quite a few loops to get it. (cherry picked from commit 4b10240cca0dc0a4e82e42959545d2ae7e622d29)
2017-02-22correct cross & disappear progress detectionDavid Kalnischkies
Given that we use the progress information to skip over actions dpkg has already done like not purging a package which was already removed and had no config files or not acting on disappeared packages and such it is important that apt and dpkg agree on which states the package has to pass through. To ensure that we keep tabs on this in the future a warning is added at the end if apt hasn't seen all the action it was supposed to see. I can't wait for the first bugreporters to wonder about this… (cherry picked from commit dabe9e2482180ada77d2adda2b3c03db22059fb8)
2017-02-22reset HOME, USER(NAME), TMPDIR & SHELL in DropPrivilegesDavid Kalnischkies
We can't cleanup the environment like e.g. sudo would do as you usually want the environment to "leak" into these helpers, but some variables like HOME should really not have still the value of the root user – it could confuse the helpers (USER) and HOME isn't accessible anyhow. Closes: 842877 (cherry picked from commit 34b491e735ad47c4805e63f3b83a659b8d10262b)
2017-02-22keep Release.gpg on untrusted to trusted IMS-HitDavid Kalnischkies
A user relying on the deprecated behaviour of apt-get to accept a source with an unknown pubkey to install a package containing the key expects that the following 'apt-get update' causes the source to be considered as trusted, but in case the source hadn't changed in the meantime this wasn't happening: The source kept being untrusted until the Release file was changed. This only effects sources not using InRelease and only apt-get, the apt binary downright refuses this course of actions, but it is a common way of adding external sources. Closes: 838779 (cherry picked from commit 84eec207be35b8c117c430296d4c212b079c00c1) LP: #1657440
2017-02-22don't install new deps of candidates for kept back pkgsDavid Kalnischkies
In effect this is an extension of the 6 years old commit a8dfff90aa740889eb99d00fde5d70908d9fd88a which uses the autoremover to remove packages again from the solution which are no longer needed to be there. Commonly these are dependencies of packages we end up not installed due to problem resolver decisions. Slightly less common is the situation we deal with here: a package which we wanted to upgrade sporting a new dependency, but ended up holding back. The problem is that all versions of an installed reverse dependencies can bring back a "garbage" package – we need to do this as there is nothing inherently wrong in having garbage packages installed or upgrade them, which itself would have garbage dependencies, so just blindly killing all new garbage packages would prevent the upgrade (and actually generate errors). What we should be doing is looking only at the version we will have on the system, disregarding all old/new reverse dependencies.

2017-01-17test: use downloadfile instead of apthelper download-fileJulian Andres Klode
This prevents CI failures from happening in 1.3 and 1.2 and might actually be more complete. Gbp-Dch: ignore (cherry picked from commit 803dabde5a4345ce83b3d2ffbd475786db9769d9)
2017-01-17https: Quote path in URL before passing it to curlJulian Andres Klode
Curl requires URLs to be urlencoded. We are however giving it undecoded URLs. This causes it go completely nuts if there is a space in the URI, producing requests like: GET /a file HTTP/1.1 which the servers then interpret as a GET request for "/a" with HTTP version "file" or some other non-sense. This works around the issue by encoding the path component of the URL. I'm not sure if we should encode other parts of the URL as well, this one seems to do the trick for the actual issue at hand. A more correct fix is to avoid the dequoting and (re-)quoting of URLs when a redirect occurs / a new request is sent. That's been on the radar for probably a year or two now, but nobody bothered implementing that yet. LP: #1651923 (cherry picked from commit 994515e689dcc5f963f5fed58284831750a5da03)
2016-10-04Do not read stderr from proxy autodetection scriptsJulian Andres Klode
This fixes a regression introduced in commit 8f858d560e3b7b475c623c4e242d1edce246025a don't leak FD in AutoProxyDetect command return parsing which accidentally made the proxy autodetection code also read the scripts output on stderr, not only on stdout when it switched the code from popen() to Popen().

2016-09-18VersionHash: Do not skip too long dependency linesJulian Andres Klode
If the dependency line does not contain spaces in the repository but does in the dpkg status file (because dpkg normalized the dependency list), the dpkg line might be longer than the line in the repository. If it now happens to be longer than 1024 characters, it would be skipped, causing the hashes to be out of date. Note that we have to bump the minor cache version again as this changes the format slightly, and we might get mismatches with an older src cache otherwise. Fixes Debian/apt#23
2016-09-11Coverage: Do not print messages from gcovJulian Andres Klode
We need to ignore messages from gcov. All those messages start with profiling: and are printed using vfprintf(), so the only thing we can do is add a library overriding those functions and linking apt-pkg to it.
2016-09-07test: Always install dpkg into our tests, regardless of MAJulian Andres Klode
Even if we only configure a single architecture, install dpkg, so dpkg can assert multi arch correctly. This also has the nice side effect of making single architecture and multiple architecture test cases more uniform. This fixes a regression from f878d3a862128bc1385616751ae1d78246b1bd01 ("test: Assert multi-arch in the chroot").

2016-09-07edsp: try 2 to read responses even if writing failedDavid Kalnischkies
Commit b60c8a89c281f2bb945d426d2215cbf8f5760738 improved the situation, but due to inconsistency mostly for planners, not for solvers. As the idea of hiding errors if we show another error is a bit scary (as the extern error might be a followup of our intern error, rather than the reason for our intern error as it is at the moment) we don't discard the errors, but if we got an extern error we show them directly removing them from the error list at the end of the run – that list will contain the extern error which hopefully gives us the best of both worlds. The problem itself is the same as before: The externals exiting before apt is done talking to them. Reported-By: Johannes 'josch' Schauer on IRC
2016-09-02acquire: Use priority queues and a 3 stage pipeline designJulian Andres Klode
Employ a priority queue instead of a normal queue to hold the items; and only add items to the running pipeline if their priority is the same or higher than the priority of items in the queue. The priorities are designed for a 3 stage pipeline system: In stage 1, all Release files and .diff/Index files are fetched. This allows us to determine what files remain to be fetched, and thus ensures a usable progress reporting. In stage 2, all Pdiff patches are fetched, so we can apply them in parallel with fetching other files in stage 3. In stage 3, all other files are fetched (complete index files such as Contents, Packages). Performance improvements, mainly from fetching the pdiff patches before complete files, so they can be applied in parallel: For the 01 Sep 2016 03:35:23 UTC -> 02 Sep 2016 09:25:37 update of Debian unstable and testing with Contents and appstream for amd64 and i386, update time reduced from 37 seconds to 24-28 seconds. Previously, apt would first download new DEP11 icon tarballs and metadata files, causing the CPU to be idle. By fetching the diffs in stage 2, we can now patch our contents and Packages files while we are downloading the DEP11 stuff.
2016-09-02CMake: test/libapt: Use a prebuilt GTest library if availableJulian Andres Klode
If a non-existing source directory is specified, try finding the system gtest library. Debian derived distributions are a bit strange because they only ship the source code and not the library...
2016-09-01support long keyid and fingerprint in gpgv's GOODSIGDavid Kalnischkies
In gpgv1 GOODSIG (and the other messages of status-fd) are documented as sending the long keyid. In gpgv2 it is documented to be either long keyid or the fingerprint. At the moment it is still the long keyid, but the documentation hints at the possibility of changing this. We care about this for Signed-By support as we detect this way if the right fingerprint has signed this file (or not). The check itself is done via VALIDSIG which always is a fingerprint, but there must also be a GOODSIG (as expired sigs are valid, too) found to be accepted which wouldn't be found in the fingerprint-case and the signature hence refused.

2016-09-01test-apt-cdrom: Fix for gnupg 2.1.15Julian Andres Klode
gpg annoyingly changed its output and broke our test suite again by adding two extra lines about key type and issuer. Really annoying. Those lines also have more than one space after the colon, so let's use \s* there - and also change the other lines to support variable length whitespace in case gpg decides to break things there too.

2016-08-31Fix segfault and out-of-bounds read in Binary fieldsJulian Andres Klode
If a Binary field contains one or more spaces before a comma, the code produced a segmentation fault, as it accidentally set a pointer to 0 instead of the value of the pointer. If the comma is at the beginning of the field, the code would create a binStartNext that points one element before the start of the string, which is undefined behavior. We also need to check that we do not exit the string during the replacement of spaces before commas: A string of the form " ," would normally exit the boundary of the Buffer: binStartNext = offset 1 ',' binEnd = offset 0 ' ' isspace_ascii(*binEnd) = true => --binEnd => binEnd = - 1 We get rid of the problem by only allowing spaces to be eliminated if they are not the first character of the buffer: binStartNext = offset 1 ',' binEnd = offset 0 ' ' binEnd > buffer = false, isspace_ascii(*binEnd) = true => exit loop => binEnd remains 0

2016-08-29test, travis: Quieter testing with a new -qq modeJulian Andres Klode
Introduce a new -qq mode for our integration test framework, and make travis use it. The new -qq mode sets MSGLEVEL to 1. In MSGLEVEL=1, no messages are generated for passed tests, and all testcase filenames are printed in the same line. Also install first in travis, do not ls the installed output and run the install with chronic, so we only get output if it failed. Gbp-Dch: ignore
2016-08-29don't loop on pinning pkgs from absolute debs by regexDavid Kalnischkies
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. Closes: 835818
2016-08-29randomize acquire order for same type index filesDavid Kalnischkies
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.

2016-08-26test: Assert multi-arch in the chrootJulian Andres Klode
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.

2016-08-26test: Use printf "%b\n" instead of echo for strings with '\'Julian Andres Klode
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.

2016-08-26test: Make sure we always find a dpkg in status fileJulian Andres Klode
Especially on non-Debian platforms, dpkg might not list itself on the host system, and thus dpkg --assert-multi-arch fails. Gbp-Dch: ignore

2016-08-26test: Explicitly pass --admindir=var/lib/dpkg to dpkgJulian Andres Klode

2016-08-26Add missing includes and external definitionsJulian Andres Klode
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.
2016-08-25treat .ddeb files like .deb, especially for dpkgDavid Kalnischkies
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
2016-08-25show apt-key warnings in apt updateDavid Kalnischkies
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.
