Andrey Semashev	43238b75ce	Added AppVeyor CI config. AppVeyor CI is useful for testing older MSVC versions that are no longer supported by GitHub Actions.	2025-06-13 15:43:18 +03:00
Andrey Semashev	8651f245fe	Added new gcc and clang jobs to GitHub Actions.	2025-06-13 15:43:18 +03:00
Andrey Semashev	5628638ade	Added a workaround for MSVC 14.0 for BOOST_BITMASK. Apparently, MSVC 14.0 does not import type aliases into namespaces via a using-declaration. Work around the problem by enabling the use of a compiler intrinsic for deducing the underlyng type of the enum.	2025-06-12 23:56:02 +03:00
Andrey Semashev	d3a556f694	Removed gcc 4.6 GitHub Action job. The compiler doesn't support std::underlying_type trait, which is needed by BOOST_BITMASK.	2025-06-12 19:01:48 +03:00
Andrey Semashev	d533b69b87	Removed windows-2019 GitHub Actions jobs. The windows-2019 image is deprecated and will soon be removevd.	2025-06-12 18:41:01 +03:00
Andrey Semashev	1a28d9d60f	Mark bitmask_set generated by BOOST_BITMASK as deprecated. This function is not really needed and can be replaced with double negation (!!) or comparison with an enum value of zero. We should prefer to minimize polluting the user's namespace with new names.	2025-06-12 18:41:01 +03:00
Andrey Semashev	002caaa54f	Added tests for BOOST_BITMASK.	2025-06-12 18:41:01 +03:00
Andrey Semashev	f7fdaf08a3	Use C++11 underlying_type trait in BOOST_BITMASK. This bumps the language requirement to C++11, although for compilers that support the __underlying_type intrinsic this may work even in C++03 mode. The operators generated by BOOST_BITMASK now use proper underlying types for casts, which means the operators will no longer truncate bits from large enums. Also mark the operators as noexcept and constexpr (since C++14).	2025-06-12 18:40:55 +03:00
Andrey Semashev	5b10a0b9b5	Removed outdated GHA images, added new compilers.	2025-04-19 19:19:12 +03:00
René Ferdinand Rivera Morell	a54b2619f8	Add support for modular build structure. (#24 ) * Make the library modular usable. * Switch to library requirements instead of source. As source puts extra source in install targets. * Add missing b2 testing module import. * Add missing import-search for cconfig/predef checks. * Add requires-b2 check to top-level build file. * Bump B2 require to 5.2 * Update copyright dates. * Move inter-lib dependencies to a project variable and into the build targets. * Update build deps.	2024-08-19 01:25:34 +03:00
Andrey Semashev	804767983f	Added macos-12 and 13 testing in addition to latest (which is 14).	2024-05-21 01:18:57 +03:00
Andrey Semashev	a8a43b4778	Use macos-latest image as macos-11 is being removed.	2024-05-21 00:59:59 +03:00
Andrey Semashev	080df0554b	Added a missing trailing newline.	2024-04-27 19:35:02 +03:00
Andrey Semashev	9c3a0022b2	Added gcc-13 and clang-17 CI jobs.	2024-02-06 00:44:24 +03:00
Andrey Semashev	6488652b08	Reduced CI job timeouts.	2024-02-05 23:43:39 +03:00
Andrey Semashev	8a0d14a862	Replaced actions/checkout usage with manual download commands. This fixes the deprecation warnings for actions/checkout@v3. actions/checkout@v4 is not functional because of the upstream bug: https://github.com/actions/checkout/issues/1590	2024-02-05 23:39:59 +03:00
Andrey Semashev	845567f026	Remove C++03 CI jobs, use gcc-11 libstdc++ in clang-12 through 15.	2023-11-17 20:07:56 +03:00
Andrey Semashev	b75c261492	Add clang-16 CI jobs, switch to clang-15 from stock Ubuntu repos.	2023-06-05 15:36:30 +03:00
Andrey Semashev	c6dac76110	Updated to GHA checkout@v3 to avoid deprecation warnings.	2022-10-18 17:56:52 +03:00
Andrey Semashev	15cc27d2bd	GitHub Actions config update. - Added gcc-12 and clang-13 through 15 jobs. - Added C++23 testing for gcc and clang on Linux. - Updated clang version for UBSAN job. - Updated Ubuntu version for clang jobs to avoid having to use external APT repository. - Updated python package installation for compatibility with Ubuntu 22.04.	2022-09-10 01:09:35 +03:00
Andrey Semashev	f9888ad051	Use ubuntu-latest for GHA CI jobs that run in a container.	2022-08-14 14:05:52 +03:00
Andrey Semashev	00efa0a0fb	Removed compiler options that are not supported by clang-cl.	2022-08-14 11:36:17 +03:00

Andrey Semashev	0583b51d35	Updated GHA CI config to remove deprecated Windows and Ubuntu images.	2022-08-14 02:06:31 +03:00
Andrey Semashev	90d5395868	Switch to macos-11 GHA image as macos-10.15 is deprecated.	2022-08-12 15:56:52 +03:00
Andrey Semashev	8c603a1894	Fixed copyright character encoding in css. Replaced ISO-8859-1 copyright character with (c) and changed the order of date and name to be consistent with other copyrights. Closes https://github.com/boostorg/detail/pull/22.	2022-02-03 11:58:40 +03:00
Andrey Semashev	fc31e65e0d	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 00:38:41 +03:00
Andrey Semashev	c5de1e6848	Another fix in git version check.	2021-09-26 20:36:43 +03:00
Andrey Semashev	ab84a1cb11	Fixed git version check on Mac OS.	2021-09-26 20:34:00 +03:00
Andrey Semashev	2ca25f118d	Fix running multiple configs of test_utf8_codecvt in parallel. When running multiple different configurations of test_utf8_codecvt, e.g. debug/release or different C++ versions, the test used to spuriously fail because the test processes would conflict through the files the test creates. To work around this, the test now creates the files in the same directory where the test executable is located. With Boost.Build, that means the files will be created in different directories for different configs. This should fix spurious test failures in CI.	2021-09-16 01:26:08 +03:00
Andrey Semashev	399a7a65b8	Added GHA CI timeout.	2021-09-15 21:30:44 +03:00
Andrey Semashev	3986d6b7e6	Updated test_utf8_codecvt to show data differences on test failures.	2021-09-12 20:57:37 +03:00
Andrey Semashev	b9f29ff43a	Added GitHub Actions config.	2021-09-12 19:34:54 +03:00
Andrey Semashev	3ec1c642f0	Removed Travis CI config file. Since Travis CI no longer runs free jobs for open source projects, we are switching to GitHub Actions.	2021-09-12 19:24:52 +03:00
Andrey Semashev	87489a4346	Fixed inconsistent linkage specification on MSVC. Code cleanup. `cc32906071` introduced inconsistent BOOST_UTF8_DECL markup between function declarations and definitions, which caused MSVC build errors. This commit fixes this. Also, replaced unneeded BOOST_UTF8_DECL markup with inline for functions that are only used internally. Made get_cont_octet_out_count static. Additionally, removed duplicate octet1_modifier_table definitions and moved it to a function-local static. Whitespace and formatting cleanup. Closes https://github.com/boostorg/filesystem/issues/204.	2021-08-18 00:47:12 +03:00
Robert Ramey	db4c8248c0	Merge commit 'a01fe6d57b906edf0400daebfb5ea88bb4582f44' into develop * commit 'a01fe6d57b906edf0400daebfb5ea88bb4582f44': Update CMakeLists.txt Fixed out-of-bounds access in utf8_codecvt_facet::do_length. Update maintainer list Disabled libstdc++ debug mode to work around gcc 10.1 bug. Added a workaround for removed nested typedefs in std::allocator. Added a workaround for C++20 ostream having deleted operator<< for wchar_t. Added gcc 10 build jobs to Travis CI. Use more up-to-date location of lightweight_test.hpp Converted binary_search_test to lightweight_test.hpp Converted allocator_utilities_test to lightweight_test.hpp Converted blank_test to lightweight_test.hpp. Removed use of deprecated header boost/detail/iterator.hpp. Reordered includes. Added boost/config.hpp. Changed because config.hpp is not being included Added clang-10 jobs to Travis CI. Change __BORLANDC__ to BOOST_BORLANDC, which is defined in Boost config for the Embarcadero non-clang-based compilers. Disabled OS X builds because they are slow on Travis CI. Updated CI configs, added compilers.	2021-08-14 11:08:29 -07:00

Peter Dimov	a01fe6d57b	Update CMakeLists.txt	2021-06-10 01:15:48 +03:00
Andrey Semashev	131208d8cc	Fixed out-of-bounds access in utf8_codecvt_facet::do_length. The loop in do_length used to dereference from_end pointer, which could point to an out-of-bounds memory. Rewritten the loop to avoid this and also make the logic a bit more clear. Closes https://github.com/boostorg/detail/pull/21.	2021-03-17 14:12:36 +03:00
