2016-11-24skip unconfigure for unconfigured to-be removed pkgsDavid Kalnischkies
2016-11-24do not configure unconfigured to be removed packagesDavid Kalnischkies
We try to configure all packages at the end which need to be configured, but that also applies to packages which weren't completely installed (e.g. maintainerscript failed) we end up removing in this interaction instead. APT doesn't perform this explicit configure in the end as it is using "dpkg --configure --pending", but it does confuse the progress report and potentially also hook scripts.

2016-11-24don'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.
2016-11-24improve 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.
2016-11-23correct 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…
2016-11-23react to trig-pend only if we have nothing else to doDavid Kalnischkies
If a package is triggered dpkg frequently issues two messages about it causing us to make a note about it both times which messes up our planned dpkg actions view. Adding these actions if we have nothing else planned fixes this and should still be correct as those planned actions will deal with the triggering just fine and we avoid strange problems like a package triggered before its removed…
2016-11-22Do not use MD5SumValue for Description_md5()Julian Andres Klode
Our profile says we spend about 5% of the time transforming the hex digits into the binary format used by HashsumValue, all for comparing them against the other strings. That makes no sense at all. According to callgrind, this reduces the overall instruction count from 5,3 billion to 5 billion in my example, which roughly matches the 5%.
2016-11-22debListParser: Micro-optimize AvailableDescriptionLanguages()Julian Andres Klode
Generating a string for each version we see is somewhat inefficient. The problem here is that the Description tag names are longer than 15 byte, and thus require an allocation on the heap, which we should avoid. It seems reasonable that 20 characters works for all languages codes used for archive descriptions, but if not, there's a warning, so we'll catch that. This should improve performance by about 2%.
2016-11-22Compare size before data when ordering cache bucket entriesJulian Andres Klode
This has the effect of significantly reducing actual string comparisons, and should improve the performance of FindGrp a bit, although it's hardly measureable (callgrind says it uses 10% instructions less now).
2016-11-22Optimize VersionHash() to not need temporary copy of inputJulian Andres Klode
Stop copying stuff, and just parse the bytes one by-one to the newly created AddCRC16Byte. This improves the instruction count for an update run from 720,850,121 to 455,801,749 according to callgrind.
2016-11-22Introduce tolower_ascii_unsafe() and use it for hashingJulian Andres Klode
This one has some obvious collisions for non-alphabetical characters, like some control characters also hashing to numbers, but we don't really have those, and these are hash functions which are not collision free to begin with.
2016-11-22Bump the cache major version for non-backportable changesJulian Andres Klode
We already have two stable series with major version 10, and the next commits will introduce non-backportable performance changes that affect the cache algorithms, so we need to bump the major version now to prevent future problems.
2016-11-22debListParser: Convert to use pkgTagSection::Key-based lookupJulian Andres Klode
This basically gets rid of 40-50% of the hash table lookups, making things a bit faster that way, and the profiles look far cleaner.
2016-11-22TagSection: Introduce functions for looking up by key idsJulian Andres Klode
Introduce a new enum class and add functions that can do a lookup with that enum class. This uses triehash.

2016-11-22TagSection: Extract Find() methods taking Pos instead of KeyJulian Andres Klode
This allows us to add a perfect hash function to the tag file without having to reimplement the methods a second time.
2016-11-22TagSection: Split AlphaIndexes into AlphaIndexes and BetaIndexesJulian Andres Klode
Move the use of the AlphaHash to a new second hash table in preparation for the arrival of the new perfect hash function. With the new perfect hash function hashing most of the keys for us, having 128 slots for a fallback hash function seems enough and prevents us from wasting space.

2016-11-11apt-ftparchive: Support NotAutomatic and ButAutomaticUpgrades fieldsJames Clarke
This also changes Acquire-By-Hash to be "yes" rather than "true", so it is consistent with dak's output. Closes: #272557
2016-11-11show distribution mismatch for changed codenamesDavid Kalnischkies
We have the last Release file around for other checks, so its trivial to look if the new Release file contains a new codename (e.g. the user has "testing" in the sources and it flipped from stretch to buster). Such a change can be okay and expected, but also be a hint of problems, so a warning if we see it happen seems okay. We can only print it once anyhow and frontends and co are likely to ignore/hide it.
2016-11-11don't warn if untransformed distribution matchesDavid Kalnischkies
A suite or codename entry in the Release file is checked against the distribution field in the sources.list entry that lead to the download of that Release file. This distribution entry can contain slashes in the distribution field: deb http://security.debian.org/debian wheezy/updates main However, the Release file may only contain "wheezy" in the Codename field and not "wheezy/updates". So a transformation needs to take place that removes the last / and everything that comes after (e.g. "/updates"). This fails, however, for valid cases like a reprepro snapshot where the given Codename contains slashes but is perfectly fine and doesn't need to be transformed. Since that transformation is essentially just a workaround for special cases like the security repository, it should be checked if the literal Codename without any transformations happened is valid and only if isn't the dist should be checked against the transformated one. This way special cases like security.debian.org are handled and reprepro snapshots work too. The initial patch was taken as insperationto move whole transformation to CheckDist() which makes this method more accepting & easier to use (but according to codesearch.d.n we are the only users anyhow). Thanks: Lukas Anzinger for initial patch Closes: 644610
2016-11-11add hidden config to set packages as Essential/ImportantDavid Kalnischkies
You can pretty much achieve the same with a local dummy package if you want to, but libapt has an inbuilt setting for essential: "apt" which can be overridden with this option as well – it could be helpful in quick tests and what not so adding this alternative shouldn't really hurt much. We aren't going to document them much through as care must be taken in regards to the binary caches as they aren't invalidated by config options alone, so the effects of old settings could still be in them, similar to the other already existing pkgCacheGen option(s). Closes: 767891 Thanks: Anthony Towns for initial patch
2016-11-11http: skip connection cleanup if we close it anyhowDavid Kalnischkies
Suggested in #529794
2016-11-11http: clear content before reporting the failureEdgar Fuß
[Comment from commiter:] I have the feeling that the issue itself is fixed for a while already as nowadays we have testcases involving a webserver closing the connection on error (look for "closeOnError") and no even remotely recent reports about it, but moving the content clearance above the failure report is a valid change and shouldn't hurt. Closes: #465572
2016-11-11add TMP/TEMP/TEMPDIR to the TMPDIR DropPrivileges danceDavid Kalnischkies
apt tools do not really support these other variables, but tools apt calls might, so lets play save and clean those up as needed. Reported-By: Paul Wise (pabs) on IRC
2016-11-10travis: ignore profiling warning in test diffsDavid Kalnischkies
On Travis CI running tests with code coverage enabled sometimes generates lines like: profiling:/path/to/file.gcda:Merge mismatch for function 257 It would be nice if we could resolve this somehow as it garbles the statistics, but until then it is far more annoying that this causes test failures for no good reason. Gbp-Dch: Ignore

2016-11-10improve SOCKS error messages for http slightlyDavid Kalnischkies
The 0.0.0.0:0 tor reports is pretty useless by itself, but even if an IP would be reported it is better to show the user the hostname we wanted the proxy to connect to in the same error message. We improve upon it further by looking for this bind address in particular and remap error messages slightly to give users a better chance of figuring out what went wrong. Upstream Tor can't do that as it is technically wrong.
2016-11-09rename Checksum-FileSize to Filesize in hashsum mismatchDavid Kalnischkies
Some people do not recognize the field value with such an arcane name and/or expect it to refer to something different (e.g. #839257). We can't just rename it internally as its an avoidance strategy as such fieldname existed previously with less clear semantics, but we can spare the general public from this implementation detail.
2016-11-09show the conflicting distribution warning againDavid Kalnischkies
Sometimes you should really act upon your todos. Especially if you have placed them directly in the code. Closes: 841874
2016-11-09reset 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

2016-11-09add support for Build-Depends/Conflicts-ArchJohannes Schauer
These new enum values might cause "interesting" behaviour in tools not expecting them – like an old apt would think a Build-Conflicts-Arch is some sort of Build-Depends – but that can't reasonably be avoided and effects only packages using B-D/C-A so if there is any breakage the tools can easily be adapted. The APT_PKG_RELEASE number is increased so that libapt users can detect the availability of these new enum fields via: #if APT_PKG_ABI > 500 || (APT_PKG_ABI == 500 && APT_PKG_RELEASE >= 1) Closes: #837395
2016-11-09fix testcase expecting incorrect remove log from dpkgDavid Kalnischkies
dpkg 1.18.11 includes: * Do not log nor print duplicate dpkg removal action. We print “Removing <package> (<version>)” lines and log remove action twice when purging a package from frontends, because they usually first call --remove and then --purge sequentially. When purging a package which is already in config-files (i.e. it has been removed before), do not print nor log the remove action.
2016-11-09Do not (re)start "apt-daily.system"Michael Vogt
This unit runs unattended-upgrades. If apt itself is part of the upgrade a restart of the unit will kill unattended-upgrades. This will lead to an inconsistent dpkg status. Closes: #841763 Thanks: Alexandre Detiste
2016-11-02keep 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
2016-11-02don'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. Reported-By: Stuart Prescott (themill) on IRC
