apt/apt-pkg/contrib/configuration.cc, branch 2.9.15

Rewrite hidden config option checker for more patterns

2024-11-22T12:40:10Z

The previous version allowed only foo::*::bar as a pattern, now you can have as many starred parts as you want allowing for a finer control instead of hardcoding specific common star-values or giving up with **. It also adds a new INVALID type for an option to mark options which should not be used, but are covered by a pattern which would normally allow it. Our tests are more or less the only users of this hidden feature making this change not very risky even through it has no dedicated test itself.

apt-pkg/contrib/configuration.cc: prepare for APT::StringView -> std::string_view

Modernize standard library includes

2024-02-20T12:49:04Z

This was automated with sed and git-clang-format, and then I had to fix up the top of policy.cc by hand as git-clang-format accidentally indented it by two spaces.

Prevent infinite loop in `ReadConfigFile`

2023-12-29T06:40:40Z

Break the loop on failure. Without this, the function goes into an infinite loop if `FName` is a directory.

configuration: Add missing #include

2021-02-24T09:47:51Z

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; ^

Avoid overstepping bounds in config file parsing

2021-02-03T16:43:13Z

Our configuration files are not security relevant, but having a parser which avoids crashing on them even if they are seriously messed up is not a bad idea anyway. It is also a good opportunity to brush up the code a bit avoiding a few small string copies with our string_view.

Retire and deprecate _strtabexpand

2021-02-03T16:36:45Z

If the Configuration code calling this was any indication, it is hard to use – and even that monster still caused heap-buffer-overflow errors, so instead of trying to fix it, lets just use methods which are far easier to use. The question why this is done at all remains, but is left for another day as an exercise for the reader.

Fail ConfigDir reading if directory listing failed

2021-02-03T16:36:45Z

We were printing an error and hence have non-zero exit code either way, but API wise it makes sense to have this properly reported back to the caller to propagate it down the chain e.g. while parsing #include stanzas.
