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`.

Основной репозиторий проекта перемещен на
https://gitflic.ru/project/erthink/libmdbx, так как 15 апреля
2022 администрация Github без предупреждения и без объяснения
причин удалила libmdbx вместе с массой других проектов,
одновременно заблокировав доступ многим разработчикам. По той
же причине Github навсегда занесен в черный список.
На случай если это была случайность или ошибка мы ждали 5
суток (три рабочих дня), но чуда не случилось. Github умер, как
и многие декларируемые либеральные ценности (свобода слова,
презумпция невиновности и право на суд, неприкосновенность
личности и частной собственности и т.д.).

The origin repository of the project has been moved to
https://gitflic.ru/project/erthink/libmdbx since on April 15,
2022, the Github administration, without warning and without
explanation, deleted libmdbx along with a lot of other
projects, simultaneously blocking access to many developers.
For the same reason Github is blacklisted forever.
In case it was an accident or a mistake, we waited 5 days
(three working days), but no miracle happened. So Github is
died, as well as many declared liberal values (freedom of
speech, presumption of innocence and right to trial,
inviolability of the person and private property, etc).

Fixes https://github.com/ledgerwatch/erigon/issues/3874.
This was a minor regression after the c4a5325aafd3f03ce7520731b9da7253d7d178f0
that affects only debug builgs (with enabled assertions) and only when the added
code catch a incoherency of unified page/buffer cache.
