Release v0.10.2 (obsolete)

Acknowledgements:

• Alex Sharov for reporting and testing.
• Andrea Lanfranchi for reporting bugs.
• Lionel Debroux for fuzzing tests and reporting bugs.
• Sergey Fedotov for node-mdbx NodeJS bindings.
• Kris Zyp for lmdbx-store NodeJS bindings.
• Noel Kuntze for draft Python bindings.

New features, extensions and improvements:

• Allow to predefine/override MDBX_BUILD_TIMESTAMP for builds reproducibility.
• 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.

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.
• Fixed log a warning during a new DB creation.
• Fixed false-negative mdbx_cursor_eof() result.
• Fixed make install with non-GNU install utility (OSX, BSD).
• Fixed installation by CMake in special cases by complete use GNUInstallDirs's variables.
• Fixed C++ Buffer issue with std::string and alignment.
• 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.
• Fixed extra noexcept for buffer::&assign_reference().
• Fixed bootid generation on Windows for case of change system' time.
• Fixed test framework keygen-related issue.

TODO for next releases:

• Engage an "overlapped I/O" on Windows.
• Simple careful mode for working with corrupted DB.
• Move most of mdbx_chk functional to the library API.
• Replace SRW-lock on Windows to allow shrink DB with MDBX_NOTLS option.
• More flexible support of asynchronous runtime/framework(s).
• Migration guide from LMDB to MDBX.
• Get rid of dirty-pages list in MDBX_WRITEMAP mode.
• Large/Overflow pages accounting for dirty-room.
• Support for RAW devices.
• Support MessagePack for Keys & Values.
• Engage new terminology.
• Finalize C++ API (few typos and trivia bugs are still likely for now).
• Packages for Astra Linux, ALT Linux, ROSA Linux, etc.
