This updates the bundled native binaries to the LMDB 1.0 series and binds the new APIs. Opening this up for comments before shipping — it's published as 0.23.0-alpha for the reasons below.

⚠️ Breaking: the 1.0 on-disk format is incompatible with 0.9.x. Existing databases must be migrated once via mdb_dump (0.9 tools) → mdb_load (1.0 tools). DBI names are also stored NUL-terminated now.

What's new

  • Opt-in page encryption and checksums. LMDB ships no cipher; the library includes hardware-accelerated AES-256-GCM (AesGcmCipher) and SHA-256 (Sha256Checksum), with LightningCipher/LightningChecksum base classes for custom implementations.
  • Two-phase commit: tx.Prepare() + env.RollbackLastTransaction(txId).
  • Incremental backup: IncrementalCopyTo / IncrementalCopyToStream / LoadIncrementalFromStream.
  • EnvironmentConfiguration.PageSize, EnvironmentOpenFlags.PreviousSnapshot, per-transaction NoSync/NoMetaSync, and the new 1.0 error codes.

Why alpha

  • The LMDB_1.0.0 release tag doesn't compile for Windows and is missing ~20 post-release fixes to exactly the features bound here (ITS#10515, ITS#10518–10523). Binaries are built from a pinned mdb.master3 commit (7ed58053d0, self-reports 0.9.90) plus a small local mingw patch (lmdb/mingw-win32-fixes.patch). Will re-pin to the release tag and drop the patch when upstream cuts 1.0.1.
  • Upstream quirk found while testing: after mdb_env_rollback the environment can't be reopened unless a write commits first — documented on RollbackLastTransaction and covered by a test.

Feedback welcome, particularly on the encryption API shape before it stabilizes.

@CoreyKaylor
Rebase native LMDB builds on mdb.RE/1.0
1c1ad03 
Pin to the 1.0 release-engineering tip so Windows compile/runtime fixes
land from upstream (ITS#10538-10539, ITS#10542) and replace the larger
local mingw patch with a minimal SIZE_T MAP() type fix. Rebuild all
native runtimes against that pin.
