mdbx: release v0.11.13 (Swashplate)

The stable bugfix release in memory of [Boris Yuryev](https://ru.wikipedia.org/wiki/Юрьев,_Борис_Николаевич) on his 133rd birthday. Fixes: ------ - Fixed builds with older libc versions after using `fcntl64()` (backport). - Fixed builds with older `stdatomic.h` versions, where the `ATOMIC_*_LOCK_FREE` macros mistakenly redefined using functions (backport). - Added workaround for `mremap()` defect to avoid assertion failure (backport). - Workaround for `encryptfs` bug(s) in the `copy_file_range` implementation (backport). - Fixed unexpected `MDBX_BUSY` from `mdbx_env_set_option()`, `mdbx_env_set_syncbytes()` and `mdbx_env_set_syncperiod()` (backport). - CMake requirements lowered to version 3.0.2 (backport). - Added admonition of insecure for RISC-V (backport). Minors: ------- - Minor clarification output of `--help` for `mdbx_test` (backport). - Added admonition of insecure for RISC-V (backport). - Stochastic scripts and CMake files synchronized with the `devel` branch. - Use `--dont-check-ram-size` for small-tests make-targets (backport). 30 files changed, 405 insertions(+), 136 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>

+
+```
+30 files changed, 405 insertions(+), 136 deletions(-)
+Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>
+```
+
+Fixes:
+
+ - Fixed builds with older libc versions after using `fcntl64()` (backport).
+ - Fixed builds with  older `stdatomic.h` versions,
+   where the `ATOMIC_*_LOCK_FREE` macros mistakenly redefined using functions (backport).
+ - Added workaround for `mremap()` defect to avoid assertion failure (backport).
+ - Workaround for `encryptfs` bug(s) in the `copy_file_range` implementation  (backport).
+ - Fixed unexpected `MDBX_BUSY` from `mdbx_env_set_option()`, `mdbx_env_set_syncbytes()`
+   and `mdbx_env_set_syncperiod()` (backport).
+ - CMake requirements lowered to version 3.0.2 (backport).
+
+Minors:
+
+ - Minor clarification output of `--help` for `mdbx_test` (backport).
+ - Added admonition of insecure for RISC-V (backport).
+ - Stochastic scripts and CMake files synchronized with the `devel` branch.
+ - Use `--dont-check-ram-size` for small-tests make-targets (backport).

+```
+
+Fixes:
+
+ - Fixed static assertion failure on platforms where the `off_t` type is wider
+   than corresponding fields of `struct flock` used for file locking (backport).
+   Now _libmdbx_ will use `fcntl64(F_GETLK64/F_SETLK64/F_SETLKW64)` if available.
+ - Fixed assertion check inside `page_retire_ex()` (backport).
+
+Minors:
+
+ - Fixed `-Wint-to-pointer-cast` warnings while casting to `mdbx_tid_t` (backport).
+ - Removed needless `LockFileEx()` inside `mdbx_env_copy()` (backport).
+
+
+## v0.11.11 (Тендра-1790) at 2022-09-11

+```
+
+Fixes:
+
+ - Fixed an extra check for `MDBX_APPENDDUP` inside `mdbx_cursor_put()` which could result in returning `MDBX_EKEYMISMATCH` for valid cases.
+ - Fixed an extra ensure/assertion check of `oldest_reader` inside `mdbx_txn_end()`.
+ - Fixed derived C++ builds by removing `MDBX_INTERNAL_FUNC` for `mdbx_w2mb()` and `mdbx_mb2w()`.

Леонид Юрьев (Leonid Yuriev)	d6b47c7bd1	mdbx: release v0.11.13 (Swashplate) The stable bugfix release in memory of [Boris Yuryev](https://ru.wikipedia.org/wiki/Юрьев,_Борис_Николаевич) on his 133rd birthday. Fixes: ------ - Fixed builds with older libc versions after using `fcntl64()` (backport). - Fixed builds with older `stdatomic.h` versions, where the `ATOMIC_*_LOCK_FREE` macros mistakenly redefined using functions (backport). - Added workaround for `mremap()` defect to avoid assertion failure (backport). - Workaround for `encryptfs` bug(s) in the `copy_file_range` implementation (backport). - Fixed unexpected `MDBX_BUSY` from `mdbx_env_set_option()`, `mdbx_env_set_syncbytes()` and `mdbx_env_set_syncperiod()` (backport). - CMake requirements lowered to version 3.0.2 (backport). - Added admonition of insecure for RISC-V (backport). Minors: ------- - Minor clarification output of `--help` for `mdbx_test` (backport). - Added admonition of insecure for RISC-V (backport). - Stochastic scripts and CMake files synchronized with the `devel` branch. - Use `--dont-check-ram-size` for small-tests make-targets (backport). 30 files changed, 405 insertions(+), 136 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>	2022-11-10 13:07:28 +03:00

Леонид Юрьев (Leonid Yuriev)	471e854551	mdbx: workaround for encryptfs's `copy_file_range()` bug(s) (backport). Выяснилось что утилита `mdbx_copy` и функции `mdbx_env_copy()` могут создавать ПРОБЛЕМЫ если целевой файл расположен в encryptfs (такая файловая система в Linux). При этом может быть четыре исхода в зависимости от версии ядра и положения звезд на небе: - всё хорошо; - плохие данные в копии без возврата ошибок; - ошибка EINVAL(22) при копировании; - oops или зависание ядра, отвал смонтированной encryptfs и т.п. В текущем понимании, причина обусловлена ошибой в коде fs, которая проявляется при использовании системного вызова `copy_file_range`.	2022-11-07 16:44:00 +03:00
Леонид Юрьев (Leonid Yuriev)	1bd0eb35bc	mdbx-cmake: исправление для совместимости с CMake 3.8 (backport).	2022-11-07 16:43:32 +03:00
Леонид Юрьев (Leonid Yuriev)	6fdae12996	mdbx: workaround for `mremap()` defect (backport). Есть основание полагать, что mremap() может возвращать MAP_FAILED, но НЕ устанавливать errno в некоторых пограничных ситуациях. Например, когда системных ресурсов не хватает на актуализацию/копирование/клонирование состояния отображения на финальной стадии, в том числе из-за раскраски исходного отображения разными флагами через madvise().	2022-10-14 14:05:44 +03:00

Леонид Юрьев (Leonid Yuriev)	290630f118	mdbx: release v0.11.12 (Эребуни) The stable bugfix release. Fixes: ------ - Fixed static assertion failure on platforms where the `off_t` type is wider than corresponding fields of `struct flock` used for file locking (backport). Now _libmdbx_ will use `fcntl64(F_GETLK64/F_SETLK64/F_SETLKW64)` if available. - Fixed assertion check inside `page_retire_ex()` (backport). Minors: ------- - Fixed `-Wint-to-pointer-cast` warnings while casting to `mdbx_tid_t` (backport). - Removed needless `LockFileEx()` inside `mdbx_env_copy()` (backport). 11 files changed, 96 insertions(+), 49 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>	2022-10-12 21:11:47 +03:00

Fixes: ------ - Fixed an extra check for `MDBX_APPENDDUP` inside `mdbx_cursor_put()` which could result in returning `MDBX_EKEYMISMATCH` for valid cases. - Fixed an extra ensure/assertion check of `oldest_reader` inside `mdbx_txn_end()`. - Fixed derived C++ builds by removing `MDBX_INTERNAL_FUNC` for `mdbx_w2mb()` and `mdbx_mb2w()`. 10 files changed, 38 insertions(+), 21 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru>	2022-09-11 14:33:56 +03:00
