mdbx: release v0.11.14 (Sergey Kapitsa)

The stable bugfix release in memory of [Sergey Kapitsa](https://en.wikipedia.org/wiki/Sergey_Kapitsa) on his 95th birthday. Fixes: ------ - backport: Fixed insignificant typo of `||` inside `#if` byte-order condition. - backport: Fixed `SIGSEGV` or an erroneous call to `free()` in situations where errors occur when reopening by `mdbx_env_open()` of a previously used environment. - backport: Fixed `cursor_put_nochecklen()` internals for case when dupsort'ed named subDb contains a single key with multiple values (aka duplicates), which are replaced with a single value by put-operation with the `MDBX_UPSERT+MDBX_ALLDUPS` flags. In this case, the database becomes completely empty, without any pages. However exactly this condition was not considered and thus wasn't handled correctly. See [issue#8](https://gitflic.ru/project/erthink/libmdbx/issue/8) for more information. - backport: Fixed extra assertion inside `override_meta()`, which could lead to false-positive failing of the assertion in a debug builds during DB recovery and auto-rollback. - backport: Refined the `__cold`/`__hot` macros to avoid the `error: inlining failed in call to ‘always_inline FOO(...)’: target specific option mismatch` issue during build using GCC >10.x for SH4 arch. Minors: ------- - backport: Using the https://libmdbx.dqdkfa.ru/dead-github for resources deleted by the Github' administration. - backport: Fixed English typos. - backport: Fixed proto of `__asan_default_options()`. - backport: Fixed doxygen-description of C++ API, especially of C++20 concepts. - backport: Refined `const` and `noexcept` for few C++ API methods. - backport: Fixed copy&paste typo of "Getting started". - backport: Update MithrilDB status. - backport: Resolve false-posirive `used uninitialized` warning from GCC >10.x while build for SH4 arch. 22 files changed, 250 insertions(+), 174 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>

+_MithrilDB_ is radically different from _libmdbx_ by the new database
+format and API based on C++20. The goal of this revolution is to provide
+a clearer and robust API, add more features and new valuable properties
+of the database. All fundamental architectural problems of libmdbx/LMDB
+have been solved there, but now the active development has been
+suspended for top-three reasons:
+
+1. For now _libmdbx_ «mostly» enough for all [our products](https://www.ptsecurity.com/ww-en/products/),
+and I’m busy in development of replication for scalability.
+2. Waiting for fresh [Elbrus CPU](https://wiki.elbrus.ru/) of [e2k architecture](https://en.wikipedia.org/wiki/Elbrus_2000),
+especially with hardware acceleration of [Streebog](https://en.wikipedia.org/wiki/Streebog) and
+[Kuznyechik](https://en.wikipedia.org/wiki/Kuznyechik), which are required for Merkle tree, etc.
+3. The expectation of needs and opportunities due to the wide use of NVDIMM (aka persistent memory),
+modern NVMe and [Ангара](https://ru.wikipedia.org/wiki/Ангара_(интерконнект)).
+
+However, _MithrilDB_ will not be available for countries unfriendly to
+Russia (i.e. acceded the sanctions, devil adepts and/or NATO). But it is
+not yet known whether such restriction will be implemented only through
+a license and support, either the source code will not be open at all.
+Basically we are not inclined to allow our work to contribute to the
+profit that goes to weapons that kill our relatives and friends.
+NO OPTIONS.
+
+Nonetheless, I try not to make any promises regarding _MithrilDB_ until release.
+
+Contrary to _MithrilDB_, _libmdbx_ will forever free and open source.
+Moreover with high-quality support whenever possible. Tu deviens
+responsable pour toujours de ce que tu as apprivois. So we will continue
+to comply with the original open license and the principles of
+constructive cooperation, in spite of outright Github sabotage and
+sanctions. I will also try to keep (not drop) Windows support, despite

Леонид Юрьев (Leonid Yuriev)	b415265d16	mdbx: release v0.11.14 (Sergey Kapitsa) The stable bugfix release in memory of [Sergey Kapitsa](https://en.wikipedia.org/wiki/Sergey_Kapitsa) on his 95th birthday. Fixes: ------ - backport: Fixed insignificant typo of `\|\|` inside `#if` byte-order condition. - backport: Fixed `SIGSEGV` or an erroneous call to `free()` in situations where errors occur when reopening by `mdbx_env_open()` of a previously used environment. - backport: Fixed `cursor_put_nochecklen()` internals for case when dupsort'ed named subDb contains a single key with multiple values (aka duplicates), which are replaced with a single value by put-operation with the `MDBX_UPSERT+MDBX_ALLDUPS` flags. In this case, the database becomes completely empty, without any pages. However exactly this condition was not considered and thus wasn't handled correctly. See [issue#8](https://gitflic.ru/project/erthink/libmdbx/issue/8) for more information. - backport: Fixed extra assertion inside `override_meta()`, which could lead to false-positive failing of the assertion in a debug builds during DB recovery and auto-rollback. - backport: Refined the `__cold`/`__hot` macros to avoid the `error: inlining failed in call to ‘always_inline FOO(...)’: target specific option mismatch` issue during build using GCC >10.x for SH4 arch. Minors: ------- - backport: Using the https://libmdbx.dqdkfa.ru/dead-github for resources deleted by the Github' administration. - backport: Fixed English typos. - backport: Fixed proto of `__asan_default_options()`. - backport: Fixed doxygen-description of C++ API, especially of C++20 concepts. - backport: Refined `const` and `noexcept` for few C++ API methods. - backport: Fixed copy&paste typo of "Getting started". - backport: Update MithrilDB status. - backport: Resolve false-posirive `used uninitialized` warning from GCC >10.x while build for SH4 arch. 22 files changed, 250 insertions(+), 174 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>	2023-02-14 15:10:41 +03:00
