The stable risen release after the Github's intentional malicious disaster.
We have migrated to a reliable trusted infrastructure
-----------------------------------------------------
The origin for now is at [GitFlic](https://gitflic.ru/project/erthink/libmdbx)
since on 2022-04-15 the Github administration, without any warning nor
explanation, deleted _libmdbx_ along with a lot of other projects,
simultaneously blocking access for many developers.
For the same reason ~~Github~~ is blacklisted forever.
GitFlic already support Russian and English languages, plan to support more,
including 和 中文. You are welcome!
New:
----
- Added the `tools-static` make target to build statically linked MDBX tools.
- Support for Microsoft Visual Studio 2022.
- Support build by MinGW' make from command line without CMake.
- Added `mdbx::filesystem` C++ API namespace that corresponds to `std::filesystem` or `std::experimental::filesystem`.
- Created [website](https://libmdbx.website.yandexcloud.net/) for online auto-generated documentation.
- Used `todo4recovery://erased_by_github/` for dead (or temporarily lost) resources deleted by ~~Github~~.
- Added `--loglevel=` command-line option to the `mdbx_test` tool.
- Added few fast smoke-like tests into CMake builds.
Fixes:
------
- Fixed a race between starting a transaction and creating a DBI descriptor that could lead to `SIGSEGV` in the cursor tracking code.
- Clarified description of `MDBX_EPERM` error returned from `mdbx_env_set_geometry()`.
- Fixed non-promoting the parent transaction to be dirty in case the undo of the geometry update failed during abortion of a nested transaction.
- Resolved linking issues with `libstdc++fs`/`libc++fs`/`libc++experimental` for C++ `std::filesystem` or `std::experimental::filesystem` for legacy compilers.
- Added workaround for GNU Make 3.81 and earlier.
- Added workaround for Elbrus/LCC 1.25 compiler bug of class inline `static constexpr` member field.
- [Fixed](https://github.com/ledgerwatch/erigon/issues/3874) minor assertion regression (only debug builds were affected).
- Fixed detection of `C++20` concepts accessibility.
- Fixed detection of Clang's LTO availability for Android.
- Fixed build for ARM/ARM64 by MSVC.
- Fixed non-x86 Windows builds with `MDBX_WITHOUT_MSVC_CRT=ON` and `MDBX_BUILD_SHARED_LIBRARY=ON`.
Minors:
-------
- Resolve minor MSVC warnings: avoid `/INCREMENTAL[:YES]` with `/LTCG`, `/W4` with `/W3`, the `C5105` warning.
- Switched to using `MDBX_EPERM` instead of `MDBX_RESULT_TRUE' to indicate that the geometry cannot be updated.
- Added `NULL` checking during memory allocation inside `mdbx_chk`.
- Resolved all warnings from MinGW while used without CMake.
- Added inheretable `target_include_directories()` to `CMakeLists.txt` for easy integration.
- Added build-time checks and paranoid runtime assertions for the `off_t` arguments of `fcntl()` which are used for locking.
- Added `-Wno-lto-type-mismatch` to avoid false-positive warnings from old GCC during LTO-enabled builds.
- Added checking for TID (system thread id) to avoid hang on 32-bit Bionic/Android within `pthread_mutex_lock()`.
- Reworked `MDBX_BUILD_TARGET` of CMake builds.
- Added `CMAKE_HOST_ARCH` and `CMAKE_HOST_CAN_RUN_EXECUTABLES_BUILT_FOR_TARGET`.
