James E. King III	64c1df1e3e	issue-204: period::intersects incorrect for empty periods Originally identified by Coverity Scan. Zero length periods like [3, 3) cannot intersect with anything. Invalid periods like [5, 4) also cannot intersect with anything. In both cases the unit tests are wrong, and fixing them reveals the implementation is not canonical for half-open sane intervals.	2025-07-06 14:56:23 -04:00
René Ferdinand Rivera Morell	645574e5df	Add support for modular build structure. (#239 ) * Make the library modular usable. * Switch to library requirements instead of source. As source puts extra source in install targets. * Add missing NO_LIB usage requirements. * 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. * Adjust doc build to avoid boost-root references. * Update build deps. * Rework GHA to use containers for the ubuntu that are god or going away. * Remove obsolete package installs. * Need another package? * Some deepndencies are now C++11 only. Hence date_time is now also C++11 only. * Switch macOS test to use the latest version. * Remove not-needed software-properties-common package. * Remove setup gcc toolchain step. * Install some missing compilers. * Maybe the gcc builds for the specific ubuntu versions rea broken. Switch to something newer.	2025-06-27 02:30:25 +03:00
Jeff Garland	85e637cb32	minor date-time fixes for 1.81 release (#219 ) * fix typo in time_period docs (#212) Co-authored-by: Quinn O'Connor <qoconnor@fastenal.com> * Fix constexpr of gregorian::date::date(special_values) to improve perf (#214) GCC up to at least 10.2 fail to resolve gregorian::date::date(special_values) as constexpr function due to assignment to this within the constructor. Refactoring constructor to initialize the instance once leads to large performance improvement. Avoid using likely function as multiple projects define a likely macro (#216) * Iso doc fixes (#215) * to_iso_string() use "." as fractional separator The fractional separator for the various to_iso_ methods is "." not "," (per to_iso_string_type() implementation). Fix the documentation to match the implementation. * use "ISO 8601" not "iso" in documentation The standard is "ISO 8601", so use that instead of just "iso" or "ISO" in comments and documentation. * fractional seconds only included if non-zero (#110) Consistently document that the fractional seconds are only included if non-zero. Use "where fffffffff" not "were fff". * Fix ccache saving on cache hit (#211) See boostorg/boost-ci#166 * chore: bump macos runner version (#213) GitHub Action is sunsetting the macOS 10.15 Actions runner. It will stop working intermittently until being completely removed by 2022-8-30: https://github.blog/changelog/2022-07-20-github-actions-the-macos-10-15-actions-runner-image-is-being-deprecated-and-will-be-removed-by-8-30-22 Co-authored-by: Quinnsicle <qtoconnor@gmail.com> Co-authored-by: Quinn O'Connor <qoconnor@fastenal.com> Co-authored-by: Povilas Kanapickas <povilas@radix.lt> Co-authored-by: Antony Polukhin <antoshkka@gmail.com> Co-authored-by: Luke Mewburn <luke@mewburn.net> Co-authored-by: Alexander Grund <Flamefire@users.noreply.github.com> Co-authored-by: Baoshuo Ren <i@baoshuo.ren>	2022-10-31 09:22:31 -07:00
