apt(8): Disable regular expressions and fnmatch See merge request apt-team/apt!95
2020-01-15apt(8): Disable regular expressions and fnmatchJulian Andres Klode
This is the first step. Next step will be to add warnings to apt-get and then remove support there as well.
2020-01-15netrc: Add warning when ignoring entries for unencrypted protocolsJulian Andres Klode
Commit 93f33052de84e9aeaf19c92291d043dad2665bbd restricted auth.conf entries to only apply to https by default, but this was silent - there was no information why http sources with auth.conf entries suddenly started failing. Add such information, and extend test case to cover it.
2020-01-14Remove includes of (md5|sha1|sha2).h headersJulian Andres Klode
Remove it everywhere, except where it is still needed.
2020-01-14Deprecate the Summation classes and mark them for removalJulian Andres Klode
2020-01-14Convert users of {MD5,SHA1,SHA256,SHA512}Summation to use HashesJulian Andres Klode
This makes use of the a function GetHashString() that returns the specific hash string. We also need to implement another overload of Add() for signed chars with sizes, so the existing users do not require reinterpret_cast everywhere.
2020-01-14Raise buffer size for Hashes::AddFD() from 4 KiB to 64 KiBJulian Andres Klode
Move APT_BUFFER_SIZE to macros.h and re-use it in hashes, this also might speed up stuff, the motivation for using 64 KiB buffers in fileutl.cc was precisely that after all.
2020-01-14hashes: Use Libgcrypt for hashing purposesJulian Andres Klode
Switch the code of the Hashes class to use libgcrypt, which allows us to use hardware-accelerated implementations of SHA1 and friends.
2020-01-09Merge branch 'pu/source-groups' into 'master'Julian Andres Klode
Avoid extra out-of-cache hash table deduplication for package names See merge request apt-team/apt!92
2020-01-08acquire: Move queue startup after calling log's Start()Julian Andres Klode
Startup() was checking for bad items and failing them, but we did not actually call Start() in the log, so the log might not be setup correctly. This caused a crash in python-apt when items were being failed on queue startup, as it released the GIL when Start() is being called and re-acquires it when running callbacks.
2020-01-08Avoid extra out-of-cache hash table deduplication for package namesJulian Andres Klode
We were de-duplicating package name strings in StoreString, but also deduplicating most of them by them being in groups, so we had extra hash table lookups that could be avoided in NewGroup(). To continue deduplicating names across binary packages and source packages, insert groups for source packages as well. This is also a good first step in allowing efficient lookup of packages by source package - we can extend Group later by a list of SourceVersion objects, or alternatively, simply add a by-source chain into pkgCache::Version. This change improves performance by about 10% (913 to 814 ms), while having no significant overhead on the cache size: --- before +++ after @@ -1,7 +1,7 @@ -Total package names: 109536 (2.191 k) -Total package structures: 118689 (4.748 k) +Total package names: 119642 (2.393 k) +Total package structures: 118687 (4.747 k) Normal packages: 83309 - Pure virtual packages: 3365 + Pure virtual packages: 3363 Single virtual packages: 17811 Mixed virtual packages: 1973 Missing: 12231 @@ -10,21 +10,21 @@ Total distinct descriptions: 149291 (3.583 k) Total dependencies: 484135/156650 (12,2 M) Total ver/file relations: 57421 (1.378 k) Total Desc/File relations: 18219 (437 k) -Total Provides mappings: 29963 (719 k) +Total Provides mappings: 29959 (719 k) Total globbed strings: 226993 (5.332 k) Total slack space: 26,8 k -Total space accounted for: 38,1 M +Total space accounted for: 38,3 M Total buckets in PkgHashTable: 50503 - Unused: 5727 - Used: 44776 - Utilization: 88.6601% - Average entries: 2.65073 + Unused: 5728 + Used: 44775 + Utilization: 88.6581% + Average entries: 2.65074 Longest: 60 Shortest: 1 Total buckets in GrpHashTable: 50503 - Unused: 5727 - Used: 44776 - Utilization: 88.6601% - Average entries: 2.44631 - Longest: 10 + Unused: 4649 + Used: 45854 + Utilization: 90.7946% + Average entries: 2.60919 + Longest: 11 Shortest: 1
2020-01-07Only define likely/unlikely if APT_COMPILING_APT setJulian Andres Klode
This ensures that we do not leak simple words like that.
2020-01-07Remove various unused macros like MAX/MIN/ABS/APT_CONSTJulian Andres Klode
We don't use them, APT_CONST is APT_PURE now, and MAX/MIN/etc are available as proper templates in the C++ standard library.
2020-01-07Rename _count() macro to APT_ARRAY_SIZE()Julian Andres Klode
2020-01-07Avoid #define _error, use anonymous C++ struct insteadJulian Andres Klode
Replace the macro with an anonymous struct that provides an inline operator->() returning the _error pointer. This change is ABI compatible, and the inline macro is not exported. We should consider if we want to avoid the function call and directly export the thread_local variable instead, when we do break ABI. Closes: #948338

2019-12-02netrc: Restrict auth.conf entries to https by defaultJulian Andres Klode
This avoids downgrade attacks where an attacker could inject Location: http://private.example/ and then (having access to raw data to private.example, for example, by opening a port there, or sniffing network traffic) read the credentials for the private repository. Closes: #945911
2019-11-27Remove failed trusted signature instead of index on IMS hitDavid Kalnischkies
While passing the combi Release and Release.gpg to the gpgv method for verification the filename of Release is placed where usually Release.gpg is assumed in the rest of the code. The "usual" cases like passing verification and failing verification ending in an error are taking care of this, but the code path dealing with a failed verification, but ignoring said failure (e.g. due to trusted=yes) was not which results in the wrong file being removed later on (in case the index happens to be unmodified since the last update call) leading us into the abyss of strange failures (fixed in the previous commit) were nothing should have changed. This is not a security issue in this form as the repository needs to fail verification & the user forcing apt to ignore the failure and carry on anyhow. It does show however how complicated the code and its various interconnected paths can become. Reported-By: Val "pinkieval" Lorentz on IRC
2019-11-27Use correct filename on IMS-hit reverify for indicesDavid Kalnischkies
If we have no old Release file, but old indices we can't compare hashsums with the new Release file and hence must request the indices again and have to react to IMS hits if they didn't change. We used to symlink the old index file to the partial directory, but that usually meant that we linked an uncompressed file to a compressed file, which not all uncompressors can deal with transparently resulting in strange failures. We could do without the symlink, but that would require changes in the codepaths dealing with failure as they would rename the file to FAILED.
2019-11-26Fix some style warnings from cppcheckDavid Kalnischkies
Unused variable, std::algorithms instead of raw for-loops. There should be no observeable difference in behaviour. Reported-By: cppcheck Gbp-Dch: Ignore
2019-11-26patterns: Add ?sectionJulian Andres Klode
2019-11-26patterns: Add ?all-versionsJulian Andres Klode
2019-11-26patterns: Implement ?narrow(...), as ?any-version(?and(...))Julian Andres Klode
This is pure syntactic sugar - ?narrow does not exist in the abstract syntax.
2019-11-26patterns: Add ?any-versionJulian Andres Klode
2019-11-25Fix progress bar width for multibyte charsetsАлексей Шилин
When using locale in which symbols occupy more than 1 byte (for example, ru_RU.UTF-8), the progress bar width was calculated incorrectly because std::string::size() returns the number of bytes rather than the number of actual characters. Use the newly introduced APT::String::DisplayLength() to calculate the width instead.
2019-11-25strutl: Add APT::String::DisplayLength() functionАлексей Шилин
Returns string length, but unlike std::string::size() it honors multibyte characters. This allows to properly calculate visible sizes of console messages.
2019-11-25patterns: Add ?originJulian Andres Klode
2019-11-25patterns: Add ?archiveJulian Andres Klode
2019-11-25patterns: Add ?source-name and ?source-versionJulian Andres Klode
2019-11-25patterns: Add ?versionJulian Andres Klode
2019-11-25patterns: Add base class for regular expression matchingJulian Andres Klode
2019-11-25Search in all available description translationsАлексей Шилин
When multiple translations of package descriptions are available, perform search in all of them. It allows using search patterns in any of the configured languages. Previously, only the first available translation was searched. As the result, patterns in e.g. English never matched packages which had their descriptions translated into local language. Closes: #490000
2019-09-19Pass --abort-after=1 to dpkg when using --force-dependsJulian Andres Klode
Using --force-depends causes dpkg to continue removing packages a package depends upon even if that package fails to be removed, because dpkg turns off all sanity checks. So we gotta tell dpkg to stop immediately if there's an error removing stuff. Closes: #935910 LP: #1844634
2019-08-22srvrec: Use re-entrant resolver functionsJulian Andres Klode
This should probably make those functions thread-safe, which might be useful for some external users.
2019-08-19patterns: Allow more complex wordsJulian Andres Klode
Only disallow ,() and on the start of a word also ~ and ?. Make sure to include \0 as disallowed.
2019-08-15patterns: Improve error reporting at end of argument listJulian Andres Klode
2019-08-15Add ?virtual patternJulian Andres Klode
This matches any package that does not have versions.
2019-08-15Add the ?exact-name patternJulian Andres Klode
The ?exact-name pattern matches the name exactly, there is no substring matching going on, or any regular expression or fnmatch magic.
2019-08-15Add ?essential patternJulian Andres Klode
This matches all packages where at least one of the versions is marked essential; or well, whenver apt considers a package essential.
2019-08-15Add ?broken patternJulian Andres Klode
This matches all packages that have broken dependencies in the installed version or the version selected for install.
2019-08-15Add ?config-files and ?installed patternsJulian Andres Klode
These two are mutually exclusive states of installed-ness. And ?installed package is fully unpacked and configured; a ?config-files package only has config files left.
2019-08-15Add ?obsolete and ?upgradable patternsJulian Andres Klode
These match packages that have no version in a repository, or where an upgrade is available. Notably, ?and(?obsolete,?upgradable) == ?false because an upgradable package is by definition not obsolete.
2019-08-15Add ?automatic and ?garbage patternsJulian Andres Klode
These patterns allow you to identify automatically installed packages, as well as automatically installed packages that are no longer reachable from the manually installed ones.
2019-08-15Add patterns for the existing CacheFilter::Matcher classesJulian Andres Klode
This implements the basic logic patterns: ?and ?false ?not ?or ?true and the basic package patterns: ?architecture ?name ?x-name-fnmatch
2019-08-15Add pattern tree parser infra and connect with cacheset and apt listJulian Andres Klode
This adds a transformation from parse tree into a CacheFilter and connects it with cachesets and the apt list command.
2019-08-15Add initial support for parsing patterns into parse treesJulian Andres Klode
Introduce a parser for patterns that generates a parse tree. The language understood by the parser is: pattern = '?'TERM | '?'TERM '(' pattern (',' pattern)* ','? ')' | WORD | QUOTED-WORD TERM = [0-9a-zA-Z-] WORD = [0-9a-ZA-Z-.*^$\[\]_\\] QUOTED_WORD = "..." # you know what I mean This language is context free, which is a massive simplification from aptitude's language, where ?foo(bar) could have two different meanings depending on whether ?foo takes an argument or not.
2019-08-15Fix segfault in pkgAcquire::Enqueue() with Acquire::Queue-Mode=accessJulian Andres Klode
In commit 79b1a8298, QueueName() was changed, amongst other things, to exit early when the queue mode was single access, as single access does not need any fancy queue name. The exit became too early though, as Config was not initialized anymore, but the caller was relying on it. Fix QueueName() to always initialize Config and in Enqueue() initialize Config with a nullptr, so if this regresses it's guaranteed to fail harder. Also add a test case - this is very simple, but the first and only test case for access queue mode. Regression-Of: 79b1a82983e737e74359bc306d9edb357c5bdd46 LP: #1839714
