apt/apt-pkg/contrib, branch 2.5.0

Include our config.h in all C++ files to avoid ODR violations

2022-05-07T08:45:44Z

Some of our headers use APT_COMPILING_APT trickery to avoid exposing too broadly details we don't want external clients to know and make use of. The flip-side is that this can lead to different compilation units seeing different definitions if they aren't all using the same config.

Remove unused public zlib include from libapt fileutl.h

2022-05-07T08:45:44Z

Our public interface doesn't use zlib for quite a while now so lets drop the last remnants as hopefully nobody depends on us bringing it in… Unlike our own private lib for transitive provision of unistd.h. References: 680b916ce7203a40ebd0a3882b9a71ca77278a67

Parse Checksum fields via pkgTagSection::Key, too

2022-04-01T12:16:19Z

We abstract hashes a fair bit to be able to add new ones eventually, which lead us to building the field names on the fly. We can do better through by keeping a central place for these names, too, which even helps in reducing code as we don't need the MD5 → Files dance anymore.

Document tagfile-keys.h as internal to apt

2022-04-01T12:15:26Z

The previous regime of the file was to sort it on insert, but that changes the values in the generated enum, which is fine as long as we only use it in libapt itself, but breaks on other users. The header was always intended to be private to apt itself, so we just document this here now and lay the ground work to have the file in the future only appended to, so that it remains sufficiently ABI stable that we can use it outside the library in our apt tools. We also remove some fields apt is unlikely to need or only uses in certain cases outside of any (speed) critical path to have enough room to add more fields soon as currently we are limited to 128 fields max and it would be sad if we use up that allowance entirely already.

Introduce and use isalpha_ascii() in debversion rather than isalpha()

2022-01-06T19:56:52Z

Avoid misclassifying additional alphabetical characters from certain locales as alpha and then sort them by ASCII...

Spelling fixes

apt-pkg/contrib/srvrec.h: Explicitly include sys/types.h

2021-11-22T12:09:02Z

This avoids type errors with musl C library.

srvrec: Keep support for older resolver

2021-03-20T19:33:34Z

Some C libraries e.g. musl do not implement the new res_n* APIs therefore keep the old implementation as fallback and check __RES version macro to determine the API level Signed-off-by: Khem Raj Cc: Julian Andres Klode

RunScripts: Do not reset SIGQUIT and SIGINT to SIG_DFL

2021-03-01T20:26:24Z

This caused python-apt to unset the Python signal handler when running update or install commands, breaking KeyboardInterrupt amongst possibly other things. We do not set those signal handlers in this functions, and the calling functions restore signal handlers to previous ones. LP: #1898026

configuration: Add missing #include

As user "DaOfficialRolex" on GitHub pointed out: This is needed to allow for APT on iOS to compile correctly. If not included the two following errors happen while compiling APT. ~/apt/apt-pkg/contrib/configuration.cc:900:44: error: constexpr variable cannot have non-literal type 'const std::array' constexpr std::array magicComments { "clear"_sv, "include"_sv, "x-apt-configure-index"_sv }; ^ ~/apt/apt-pkg/contrib/configuration.cc:900:44: error: implicit instantiation of undefined template 'std::__1::array' /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/__tuple:219:64: note: template is declared here template struct _LIBCPP_TEMPLATE_VIS array; ^
