支持动态设置 thread_handling 线程模式或连接池模式。 支持主从 bp 同步功能:当发生 HA 并进行主备切换后,备库通常需要一段比较长的时间来 warmup,把热点数据加载到buffer pool。为加速备机的预热,TXSQL 支持了主从 bp 同步功能。 支持Sort Merge Join 功能。
最近工作中有地方嵌入式程序出现莫名其妙的问题,有时候正常的变量值都会突变了导致问题。 这问题还是偶然出现的神秘莫测,若没有对内存检测的神器,很难定位。 比如char buf[5], memcpy(buf,"12345678",8) ;明显超过了buf的范围,但程序竟正常运行不会报错,也没任何提示。 这里明细写出来是为了展现问题,但项目中那...

The localeconv function declared in locale.h now works correctly when per-thread locale is enabled. In previous versions of the library, this function would return the lconv data for the global locale, not the thread's locale. If you use per-thread locales, you should check your use of loc...
