mdbx: release v0.10.2 Acknowledgements: ----------------- - [Alex Sharov](https://github.com/AskAlexSharov) for reporting and testing. - [Andrea Lanfranchi](https://github.com/AndreaLanfranchi) for reporting bugs. - [Lionel Debroux](https://github.com/debrouxl) for fuzzing tests and reporting bugs. - [Sergey Fedotov](https://github.com/SergeyFromHell/) for [`node-mdbx` NodeJS bindings](https://www.npmjs.com/package/node-mdbx). - [Kris Zyp](https://github.com/kriszyp) for [`lmdbx-store` NodeJS bindings](https://github.com/kriszyp/lmdbx-store). - [Noel Kuntze](https://github.com/Thermi) for [draft Python bindings](https://github.com/erthink/libmdbx/commits/python-bindings). New features, extensions and improvements: ------------------------------------------ - [Allow to predefine/override `MDBX_BUILD_TIMESTAMP` for builds reproducibility](https://github.com/erthink/libmdbx/issues/201). - Added options support for `long-stochastic` script. - Avoided `MDBX_TXN_FULL` error for large transactions when possible. - The `MDBX_READERS_LIMIT` increased to `32767`. - Raise `MDBX_TOO_LARGE` under Valgrind/ASAN if being opened DB is 100 larger than RAM (to avoid hangs and OOM). - Minimized the size of poisoned/unpoisoned regions to avoid Valgrind/ASAN stuck. - Added more workarounds for QEMU for testing builds for 32-bit platforms, Alpha and Sparc architectures. - `mdbx_chk` now skips iteration & checking of DB' records if corresponding page-tree is corrupted (to avoid `SIGSEGV`, ASAN failures, etc). - Added more checks for [rare/fuzzing corruption cases](https://github.com/erthink/libmdbx/issues/217). Backward compatibility break: ----------------------------- - Use file `VERSION.txt` for version information instead of `VERSION` to avoid collision with `#include <version>`. - Rename `slice::from/to_FOO_bytes()` to `slice::envisage_from/to_FOO_length()'. - Rename `MDBX_TEST_EXTRA` make's variable to `MDBX_SMOKE_EXTRA`. - Some details of the C++ API have been changed for subsequent freezing. Fixes: ------ - Fixed excess meta-pages checks in case `mdbx_chk` is called to check the DB for a specific meta page and thus could prevent switching to the selected meta page, even if the check passed without errors. - Fixed [recursive use of SRW-lock on Windows cause by `MDBX_NOTLS` option](https://github.com/erthink/libmdbx/issues/203). - Fixed [log a warning during a new DB creation](https://github.com/erthink/libmdbx/issues/205). - Fixed [false-negative `mdbx_cursor_eof()` result](https://github.com/erthink/libmdbx/issues/207). - Fixed [`make install` with non-GNU `install` utility (OSX, BSD)](https://github.com/erthink/libmdbx/issues/208). - Fixed [installation by `CMake` in special cases by complete use `GNUInstallDirs`'s variables](https://github.com/erthink/libmdbx/issues/209). - Fixed [C++ Buffer issue with `std::string` and alignment](https://github.com/erthink/libmdbx/issues/191). - Fixed `safe64_reset()` for platforms without atomic 64-bit compare-and-swap. - Fixed hang/shutdown on big-endian platforms without `__cxa_thread_atexit()`. - Fixed [using bad meta-pages if DB was partially/recoverable corrupted](https://github.com/erthink/libmdbx/issues/217). - Fixed extra `noexcept` for `buffer::&assign_reference()`. - Fixed `bootid` generation on Windows for case of change system' time. - Fixed [test framework keygen-related issue](https://github.com/erthink/libmdbx/issues/127).
