2017-09-13Fix translator comment location for legacy target warningJulian Andres Klode
In commit Do not warn about duplicate "legacy" targets, we we added an if, that changed the .po files... (cherry picked from commit e9db5ba7c7631d51359967afb1d563da7637be11) Gbp-Dch: ignore
2017-09-13Do not warn about duplicate "legacy" targetsJulian Andres Klode
If a source has a legacy Contents file, and two lines mention the same archive but different components, a warning would be issued that is confusing. So, as the field is named Contents-deb-legacy, let's just not print warnings for fields containing "legacy". LP: #1697120 Closes: #839259 (cherry picked from commit 5a747462baef6cecf6ed389c7b7492443930f7ed)
2017-05-31Fix parsing of or groups in build-deps with ignored packagesJulian Andres Klode
If the last alternative(s) of an Or group is ignored, because it does not match an architecture list, we would end up keeping the or flag, effectively making the next AND an OR. For example, when parsing (on amd64): debhelper (>= 9), libnacl-dev [amd64] | libnacl-dev [i386] => debhelper (>= 9), libnacl-dev | Which can cause python-apt to crash. Even worse: debhelper (>= 9), libnacl-dev [amd64] | libnacl-dev [i386], foobar => debhelper (>= 9), libnacl-dev [amd64] | foobar By setting the previous alternatives Or flag to the current Or flag if the current alternative is ignored, we solve the issue. LP: #1694697
2017-02-10Do not package names representing .dsc/.deb/... filesJulian Andres Klode
In the case of build-dep and other commands where a file can be passed we must make sure not to normalize the path name as that can have odd side effects, or well, cause the operation to do nothing. Test for build-dep-file is adjusted to perform the vcard check once as "vcard" and once as "VCard", thus testing that this solves the reported bug. We inline the std::transform() and optimize it a bit to not write anything in the common case (package names are defined to be lowercase, the whole transformation is just for names that should not exist...) to counter the performance hit of the added find() call (it's about 0.15% more instructions than with the existing transform, but we save about 0.67% in writes...). Closes: #854794

2017-01-02ParseDepends: Support passing the desired architectureNiels Thykier
This is useful for e.g. Britney, where the Build-Depends would have to be parsed for multiple architectures.

2016-12-31fix minimum pkgs option for dpkg --recursive usageDavid Kalnischkies
Interpreting a boolean as an int works just fine – it just hasn't the intended result – it isn't a serious problem through as the disabling of the usage of this dpkg calling style is just an "optimization"
2016-12-31avoid producing invalid options if repo has no hostDavid Kalnischkies
This can happen e.g. for file: repositories. There is no inherent problem with setting such values internally, but its bad style, forbidden in the manpage and could be annoying in the future. Gbp-Dch: Ignore

Unlikely to have any practical effect, but its more consistent to use the right methods instead of performing it slightly incorrect by hand. Gbp-Dch: Ignore

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%.
2016-11-22Optimize 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.
2016-11-22debListParser: 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.
2016-11-11add 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
2016-11-09add 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
2016-09-18VersionHash: 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
2016-08-31Fix 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

2016-08-26Make directory paths configurableJulian Andres Klode
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 /.
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
2016-08-24do not restore selections for already purged packagesDavid Kalnischkies
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.

2016-08-23do dpkg --configure before --remove/--purge --pendingDavid Kalnischkies
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
2016-08-19Ignore SIGINT and SIGQUIT for Pre-Install hooksJulian Andres Klode
Instead of erroring out when receiving a SIGINT, let the child deal with it - we'll error out anyway if the child exits with an error or due to the signal. Also ignore SIGQUIT, as system() ignores it. This basically fixes Bug #832593, but: we are running the hooks via sh -c. Some shells exit with a signal error even if the command they are executing catches the signal and exits successfully. So far, this has been noticed on dash, which unfortunately, is our default shell. Example: $ cat trap.sh trap 'echo int' INT; sleep 10; exit 0 $ if dash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint FAIL: 130 $ if mksh -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint OK: 0 $ if bash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint OK: 0
2016-08-17add --with-source option and Packages/Sources supportDavid Kalnischkies
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.
