Percona Server 5.7.10-1 第一个候选版本发布，现已提供在 Percona 网站或者 Percona 软件库。此版本包括最新 Percona Server 5.6 版本的所有 bug 修复 (当前的 Percona Server 5.6.27-76.0)。 下载：https://github.com/percona/percona-server/archive/Percona-Server-5.7.10-1rc1.zip 新特性： Percona Server 5.7.10-1 is not available on RHEL 5 family of Linux distributions and Debian 6 (squeeze). Complete list of changes between Percona Server 5.6 and 5.7 can be seen in Changed in Percona Server 5.7. 已知问题： MeCab Full-Text Parser Plugin has not been included in this release. PAM Authentication Plugin currently isn’t working correctly. Variables innodb_show_verbose_locks and innodb_show_locks_help are not working correctly. In Percona Server 5.7 super_read_only feature has been replaced with upstream implementation. There are currently two known issues compared to Percona Server 5.6 implementation: Bug #78963, super_read_only aborts STOP SLAVE if variable relay_log_info_repository is set to TABLE which could lead to a server crash in Debug builds. Bug #79328, super_read_only set as a server option has no effect. Using primary key with a BLOB in TokuDB table could lead to a server crash (bug #916). Using XA transactions with TokuDB could lead to a server crash (bug #900). To install TokuDB on CentOS/RHEL 7 you’ll need to add the line LD_PRELOAD=/usr/lib64/libjemalloc.so.1 to /etc/sysconfig/mysql before running the ps_tokudb_admin script Percona Tokubackup has not been included in this release. Bugs 修复 Running ALTER TABLE without specifying the storage engine (without ENGINE= clause) or OPTIMIZE TABLE when enforce_storage_engine was enabled could lead to unrequested and unexpected storage engine changes. If done for a system table, it would circumvent regular system table storage engine compatibility checks, resulting in crashes or otherwise broken server operation. Bug fixed #1488055. Some transaction deadlocks did not increase the INFORMATION_SCHEMA.INNODB_METRICS lock_deadlocks counter. Bug fixed #1466414 (upstream #77399). Removed excessive locking during the buffer pool resize when checking whether AHI is enabled. Bug fixed #1525215 (upstream #78894). Removed unnecessary code in InnoDB error monitor thread. Bug fixed #1521564 (upstream #79477). 其他 bug 修复： #371752 (upstream #45379), #1441362 (upstream #56155), #1385062 (upstream #74810), #1519201 (upstream #79391), #1515602, #1506697 (upstream #57552), #1501089 (upstream #75239), #1447527 (upstream #75368), #1384658 (upstream #74619), #1384656 (upstream #74584), and #1192052. 更多内容请看发行说明。 Percona Server 5.7.10 RC1 发布下载地址
