Berkeley DB是历史悠久的嵌入式数据库系统，主要应用在UNIX/LINUX操作系统上，其设计思想是简单、小巧、可靠、高性能。

Berkeley DB 12cR1 (12.1.6.1.26)  发布，更新内容如下：

  1. A 'salvage' (db_dump -r) no longer hangs on a corrupt database which contains a loop in an overflow item's chain of pages. [#18550]

  2. Remove +u1 compiler flag from the HP-UX build and fixed related alignment issue.  [#23739]

  3. Fixed DB_RUNRECOVERY errors caused by pthreads-based mutexes. [#23965]

  4. Allow the failchk process to call __env_refresh when necessary. [#24194]

  5. DB->open() now detects invalid pagesizes sooner, avoiding a potential floating point exception when a purported database file has a pagesize of 0. Added a pre-verify step to the db_dump utility. [#24217]

  6. Fixed a bug that can cause DBcursor->get to return incorrect data when DB_GET_BOTH_RANGE flag is used. [#24220.1]

  7. Added support for Java 8. [#24220.2]

  8. Aborting a transaction no longer panics if a deadlock error occurs while freeing up the transaction's cursors. [#24223]

  9. Fixed a crash which could occur when multiple BDB SQL processes repeatedly open a database file. [#24230]

  10. Fixed a bug where db_printlog improperly handled a "No such file or directory" error condition. [#24265]

  11. Fixed a bug that could cause a master crash in the following cases: an unencrypted client attempts to join an encrypted replication group, or an encrypted client attempts to join an unencrypted replication group. [#24288]

  12. Fixed a bug that can cause a crash when DB_ENV->memp_stat() is called. [#24298]

  13. Added support for arm64. [#24312]

  14. Reduced the minimum hash table size. [#24314].

  15. Fixed a bug where file names were not displayed correctly when a file failed to open during backup. [#24340]

  16. Enabled cross compiling the JDBC driver. [#24347]

  17. Fixed a crash when writing to a SQL BLOB while txn_bulk is enabled. [#24351]

  18. DB->open() now detects invalid bt_minkey better, avoiding a potential floating point excetpion. [#24398]

  19. Removed EnvironmentConfig.setTxnNotDurable() and Environment.getTxnNotDurable() from the Java API. This flag cannot be set on environments. [#24416]
