GitHub migration

All tasks related to migrating our work from Microsoft-internal systems to GitHub.

Build System

• #161
• #162
• Port DLL export validation from MSBuild to CMake. (Or switch to .def.)
• Change the MSVC-internal MSBuild build system to invoke the STL's CMake build system.
• Delete stl/msbuild and celebrate!

Tests

• Finish migrating src/qa/VC/Libs/vcr/tests/cpp/Dev09_171913_tr1_windows_h_macros
  • And resolve Microsoft-internal VSO-936680
• #797
• #798

Documentation

• Write Contribution Guidelines.
• Drop the Roadmap.

Issues

• Finish migrating bugs.
  • As of 2024-05-28: 107 bugs remain.
• Create bugs for vNext overhauls, collecting DevCom/VSO bugs (tagged vclibs-wcfb02) that were closed in the pre-GitHub Team Foundation Version Control vNext era.
• Finish migrating todo.docx to enhancement issues.
  • As of 2024-05-28: 5 pages remain.
• Migrate lwg_issues_to_file.docx to LWG issue needed issues.
  • As of 2024-05-28: 2.5 pages remain.
• Migrate stl_requested_bugs.docx somewhere (possibly the STL Wiki).
• #2271

Done

• Migrated status.xlsx to microsoft.github.io/STL/, powered by Chart.js.
• #386
• #639
• #939
• Switched the internal build to use boost-math standalone:
  • #2151
  • #3077 (also migrated a Special Math test)
• Migrated tests from vcr/tests/cpp to std:
  • #2507
• Unified libcxx's expected_results.txt and skipped_tests.txt:
  • #3484
• #2310
• #820

Start by reviewing the unchecked sections and linked issues #161, #162, #797, #798, and #2271, then inspect stl/msbuild and the listed src/qa/VC/Libs/vcr/tests path. Done means the remaining build, test, documentation, and issue-migration checklist items are completed or tracked in focused issues.
