Updated check for apt-add-repository capabilities.

In Ubuntu 20.04 there appeared an updated version of the software-properties-common package in focal-updates, which ships a newer apt-add-repository version that doesn't support -P/-S/-U command line arguments. Since we cannot rely on package version checks to determine apt-add-repository capabilities, we have to parse its --help output instead. Also, made source list processing more protected against spaces.
Fixed git version check on Mac OS.

+# Boost.Parameter
+
+Boost.Parameter, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), is a header-only library that implements named parameters for functions and templates in C++.
+
+### Directories
+
+* **doc** - Documentation sources
+* **include** - Interface headers of Boost.Parameter
+* **test** - Boost.Parameter unit tests
+
+### More information
+
+* [Documentation](https://www.boost.org/libs/parameter)
+* [Report bugs](https://github.com/boostorg/parameter/issues/new). Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as [pull requests](https://github.com/boostorg/parameter/compare) against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).

Andrey Semashev	b06ee2bf8a	Updated check for apt-add-repository capabilities. In Ubuntu 20.04 there appeared an updated version of the software-properties-common package in focal-updates, which ships a newer apt-add-repository version that doesn't support -P/-S/-U command line arguments. Since we cannot rely on package version checks to determine apt-add-repository capabilities, we have to parse its --help output instead. Also, made source list processing more protected against spaces.	2021-11-16 00:57:49 +03:00
Andrey Semashev	d52fef9cb1	Fixed git version check on Mac OS.	2021-09-26 20:42:21 +03:00
Andrey Semashev	56bd845cff	Disable python tests under UBSAN because of failures.	2021-09-16 01:47:49 +03:00
Andrey Semashev	d95a1617a1	Added libpython-dev and libpython3-dev installation in containers.	2021-09-16 01:37:47 +03:00
Andrey Semashev	7192dd51a9	Fixed GHA link.	2021-09-15 21:51:35 +03:00
Andrey Semashev	40f362bea3	Updated README.md to replace Travis CI links with GitHub Actions.	2021-09-15 21:50:22 +03:00
Andrey Semashev	badc449092	Added GitHub Actions CI config.	2021-09-15 21:48:02 +03:00
Andrey Semashev	a1986ac445	Removed Travis CI config. Since Travis CI no longer runs free jobs for open source projects, we are migrating to GitHub Actions instead.	2021-09-15 21:46:49 +03:00

Andrey Semashev	e38b1160ae	Disabled python tests on Cygwin and Cygwin64 on AppVeyor CI. Python headers are not installed in Cygwin and Cygwin64, so the compiler picks up Win32 headers in C:\Python27\Include and fails.	2021-03-17 12:12:39 +03:00
Andrey Semashev	6f4cdc939d	Fixed Boost.Bind deprecated warnings in tests.	2021-03-17 11:55:40 +03:00
Andrey Semashev	63104db02c	Added a missing include in test.	2021-03-17 11:55:40 +03:00
Andrey Semashev	8f1405b880	Converted clang APT references to source lines for Tranis CI. APT references are not consistently defined for all clang versions on all Ubuntu instances, so just always use explicit APT source lines.	2021-03-17 11:55:40 +03:00
Andrey Semashev	c397e90107	Fixed a typo in AppVeyor CI config.	2021-03-17 02:58:33 +03:00

Boris Oncev	983bf6bebc	Fix default_r_ move constructor on MSVC 2015 MSVC 2015 misscompiles moves for classes containing RValue refs using the default generated move constructor when moving into a function. Example of reproduction: struct RValueHolder { std::string&& str; }; bool buggy_move(RValueHolder dead) { // here str is not referencing the string any more return dead.str == "p"; } TEST(Bug, TmpBug) { std::string p = "p"; auto t = RValueHolder{ std::move(p) }; auto res = buggy_move(std::move(t)); EXPECT_TRUE(res); } Fixes boostorg/log#132	2021-03-14 09:20:36 +00:00
Edward Diener	e16f1025d7	Merge pull request #107 from eldiener/develop [skip ci] Add "cxxstd" json field	2021-01-21 02:01:06 -05:00
Edward Diener	7d168437b7	[skip ci] Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.	2021-01-20 23:57:10 -05:00
