36a86bbc6e mdbx: fix cursor tracking inside mdbx_rebalance(). 2018-03-26 20:20:14 +03:00
Leo Yuriev
45f159ddd3 mdbx: mdbx_cursor_put(MDBX_APPEND+MDBX_NOOVERWRITE) should return MDBX_KEYEXIST instead of MDBX_EKEYMISMATCH. 
When MDBX_APPEND is used the ordering of keys is important.
Therefore MDBX_EKEYMISMATCH should me returned when given key <= last.

On the other hand, if MDBX_NOOVERWRITE is also used
then the MDBX_KEYEXIST should be returned, but not MDBX_EKEYMISMATCH.

46a3d4e0a3 mdbx: fix assertion (minor, not a malfunction). 
The `env->me_sync_pending` could be zero
when `mdbx_sync_locked()` called from `mdbx_env_set_geometry()`.

Therefore `mdbx_assert(env, !META_IS_STEADY(head) || env->me_sync_pending != 0)` at the top of `mdbx_sync_locked()`
could be trigger assertion failure.
