binary_reader held bjd_optimized_type_markers and bjd_types_map as
non-static const members (12 string_t objects for the type-name table),
built and destroyed on every from_cbor/from_msgpack/from_bson/
from_ubjson/from_bon8/from_bjdata call even though only from_bjdata
ever reads them. They also needed the #define/decltype/#undef
workaround from #3637 and two NOLINTNEXTLINE suppressions, and
binary_writer already carries the same two lists in another form
(is_bjdata_excluded_type_marker() and a local std::map in
write_bjdata_ndarray(), the latter removed by the item-4 commit), so
the excluded-marker lists could drift apart.
Replace bjd_optimized_type_markers with static constexpr
is_bjd_excluded_optimized_type(char_int_type), using the same ||-chain
as binary_writer's is_bjdata_excluded_type_marker(). Replace
bjd_types_map with a non-constexpr static bjd_type_name(char_int_type)
switch returning nullptr for an unknown marker (a C++11 constexpr
function cannot contain a switch). Delete both
JSON_BINARY_READER_MAKE_* macros, the bjd_type pair alias, the
NOLINTNEXTLINE suppressions, detail::make_array() (no longer used
anywhere), and the now-unused <algorithm> and <array> includes.
Update the two call sites (the ND-array excluded-type check and the
_ArrayType_ lookup) accordingly, and replace unit-bjdata.cpp's
"LUT arrays are sorted" section, which only checked the two tables'
internal ordering, with a check of all 12 type names and all 8
excluded markers against both new functions.
#5711 item 1
Signed-off-by: Niels Lohmann <mail@nlohmann.me>
* Add versioned inline namespace
Add a versioned inline namespace to prevent ABI issues when linking code
using multiple library versions.
* Add namespace macros
* Encode ABI information in inline namespace
Add _diag suffix to inline namespace if JSON_DIAGNOSTICS is enabled, and
_ldvcmp suffix if JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON is enabled.
* Move ABI-affecting macros into abi_macros.hpp
* Move std_fs namespace definition into std_fs.hpp
* Remove std_fs namespace from unit test
* Format more files in tests directory
* Add unit tests
* Update documentation
* Fix GDB pretty printer
* fixup! Add namespace macros
* Derive ABI prefix from NLOHMANN_JSON_VERSION_*
* Refactor unit test creation
Add functions for creating tests and to supply test- and
standard-specific build settings.
Raises minimum CMake version to 3.13 in test directory.
json_test_add_test_for(
<file>
MAIN <main>
[CXX_STANDARDS <version_number>...] [FORCE])
Given a <file> unit-foo.cpp, produces
test-foo_cpp<version_number>
if C++ standard <version_number> is supported by the compiler and
thesource file contains JSON_HAS_CPP_<version_number>. Use FORCE to
create the test regardless of the file containing
JSON_HAS_CPP_<version_number>. Test targets are linked against <main>.
CXX_STANDARDS defaults to "11".
json_test_set_test_options(
all|<tests>
[CXX_STANDARDS all|<args>...]
[COMPILE_DEFINITIONS <args>...]
[COMPILE_FEATURES <args>...]
[COMPILE_OPTIONS <args>...]
[LINK_LIBRARIES <args>...]
[LINK_OPTIONS <args>...])
Supply test- and standard-specific build settings.
Specify multiple tests using a list e.g., "test-foo;test-bar".
Must be called BEFORE the test is created.
* Use CMAKE_MODULE_PATH
* Don't undef some macros if JSON_TEST_KEEP_MACROS is defined
* Use JSON_TEST_KEEP_MACROS
Incidentally enables the regression tests for #2546 and #3070.
A CHECK_THROWS_WITH_AS in #3070 was disabled which is tracked in #3377
and a line in from_json(..., std_fs::path&) was marked with LCOV_EXCL_LINE.
* Add three-way comparison feature test macro
* Disable broken comparison if JSON_HAS_THREE_WAY_COMPARISON
* Fix redefinition of inline constexpr statics
Redelcaration of inline constexpr static data members in namespace scope
was deprecated in C++17. Fixes -Werror=deprecated compilation failures.
* Fix more test build failures due to missing noexcept
* CI: update cmake_flags test to use CMake 3.13 in test directory
Also change default for JSON_BuildTests option to depend on CMake
version.
* CI: turn *_CXXFLAGS into CMake lists
* CI: use JSON_TestStandards to set CXX_STANDARD
* CI: pass extra CXXFLAGS to standards tests
