This is output of triehash. Gbp-Dch: ignore
2016-11-25gpgv: Untrust SHA1, RIPE-MD/160, but allow downgrading to weakJulian Andres Klode
Change the trust level check to allow downgrading an Untrusted option to weak (APT::Hashes::SHA1::Weak "yes";), so it prints a warning instead of an error; and change the default values for SHA1 and RIPE-MD/160 from Weak to Untrusted.
2016-11-25show output as documented for APT::Periodic::Verbose 2Paul Wise
The documentation of APT::Periodic::Verbose doesn't match the code, specifically level 2 should apply some things differently to level 1 but does not because it uses `-le 2` instead of `-lt 2` or `-le 1`. Closes: 845599
2016-11-25optional write aptwebserver log to client specific filesDavid Kalnischkies
The test test-handle-redirect-as-used-mirror-change serves multiple clients at the same time, so the order of the output is undefined and once in a while the two clients will intermix their lines causing the grep we perform on it later to fail making our tests fail. Solved by introducing client-specific logfiles which we all grep and sort the result to have the results more stable. Git-Dch: Ignore

2016-11-25get pdiff files from the same mirror as the indexDavid Kalnischkies
In ad9416611ab83f7799f2dcb4bf7f3ef30e9fe6f8 we fall back to asking the original mirror (e.g. a redirector) if we do not get the expected result. This works for the indexes, but patches are a different beast and much simpler. Adding this fallback code here seems like overkill as they are usually right along their Index file, so actually forward the relevant settings to the patch items which fixes pdiff support combined with a redirector and partial mirrors as in such a situation the pdiff patches would be 404 and the complete index would be downloaded.
2016-11-25document which keyring formats are supported by apt-keyDavid Kalnischkies
* the good old 'simple' keyring format * the ascii armored variant since 1.4 Not supported is the (new in gpg 2.1) keybox format. Closes: 844724
2016-11-25add apt-key support for armored GPG key files (*.asc)David Kalnischkies
Having binary files in /etc is kinda annoying – not that the armored files are much better – but it is hard to keep tabs on which format the file has ("simple" or "keybox") and different gnupg versions have different default binary formats which can be confusing for users to work with (beside that it is binary). Adding support for this now will enable us in some distant future to move to armored later on, much like we added trusted.gpg.d years before the world picked it up.
2016-11-24report apt-key errors via status-fd messagesDavid Kalnischkies
We report warnings from apt-key this way already since 29c590951f812d9e9c4f17706e34f2c3315fb1f6, so reporting errors seems like a good addition. Most of those errors aren't really from apt-key through, but from the code setting up and actually calling it which used to just print to stderr which might or might not intermix them with (other) progress lines in update calls. Having them as proper error messages in the system means that the errors are actually collected later on for the list instead of ending up with our relatively generic but in those cases bogus hint regarding "is gpgv installed?". The effective difference is minimal as the errors apply mostly to systems which have far worse problems than a not as nice looking error message, which makes this pretty hard to test – but at least now the hint that your system is broken can be read in proper order (= there aren't many valid cases in which the permissions of /tmp are messed up…).

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.
