private-search: Only use V.TranslatedDescription() if good

2020-05-18T20:22:24Z

When we could not find a translated description, we were pushing V.TranslatedDescription() to the vector, but that one might not have been good either. Add the check so we don't crash later when trying to access it. LP: #1877987

apt list: Fix behavior of regex vs fnmatch vs wildcards

2020-05-04T11:08:33Z

Previously (and still in cacheset), patterns where only allowed to start with ? or ~, which ignores the fact that a pattern might just as well start with a negation, such a !~nfoo. Also, we ignored the --regex flag if it looked like this, which was somewhat bad. Let's change this all: * If --regex is given, arguments are always interpreted as regex * If it is a valid package wildcard (name or * characters), then it will be interpreted as a wildcard - this set of characters is free from meaningful overlap with patterns. * Otherwise, the argument is interpreted as a pattern. For a future version, we need to adapt parsing for cacheset and list to use a common parser, to avoid differences in their interpretation. Likely, this code will go into the pattern parser, such that it generates a pattern given a valid fnmatch argument for example.

apt(8): Wait for frontend and cache lock

2020-02-26T19:36:52Z

This is a rework of !6 with additional stuff for the frontend lock, so we can lock the frontend lock and then keep looping over dpkg lock.

Make map_pointer typesafe

2020-02-24T17:29:07Z

Instead of just using uint32_t, which would allow you to assign e.g. a map_pointer to a map_pointer, use our own smarter struct that has strict type checking. We allow creating a map_pointer from a nullptr, and we allow comparing map_pointer to nullptr, which also deals with comparisons against 0 which are often used, as 0 will be implictly converted to nullptr.

Replace map_pointer_t with map_pointer

2020-02-24T16:08:34Z

This is a first step to a type safe cache, adding typing information everywhere. Next, we'll replace map_pointer implementation with a type safe one.

Remove code tagged APT_PKG_590, add some missing includes

2020-02-18T11:48:38Z

Remove all code scheduled to be removed after 5.90, and fix files to include files they previously got from hashes.h including more headers.

Implement short patterns (patterns starting with ~)

2020-02-03T11:55:54Z

Also make pattern detector in cacheset and private's list accept such patterns. We probably should just try to parse and see if it is a (start of a) pattern.

apt(8): Disable regular expressions and fnmatch

2020-01-15T21:19:17Z

This is the first step. Next step will be to add warnings to apt-get and then remove support there as well.

Convert users of {MD5,SHA1,SHA256,SHA512}Summation to use Hashes

2020-01-14T12:10:36Z

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.

satisfy: Fix segmentation fault when called with empty argument

2019-12-06T12:48:07Z

apt satisfy "" caused a segmentation fault because we were iterating over the characters, checking if the next character was the end of the string; when it could also be the current character. Instead, check whether the next character is before the end of the string, rather than identical to the end.
