This chapter describes a lot of things that you need to know when working on the MySQL code.
MySQL サーバーは以下のスレッドを作成します:
process_alarm() to force timeouts on connections
that have been idle too long.
-DUSE_ALARM_THREAD, a dedicated thread that
handles alarms is created. This is only used on some systems where
there are some problems with sigwait() or if one wants to use the
thr_alarm() code in ones application without a dedicated signal
handling thread.
--flush-time オプションを使用したなら、
全てのテーブルを一定期間でフラッシュするためだけのスレッドを作ります。
INSERT DELAYED gets its
own thread.
mysqladmin processlist only shows the connection and INSERT
DELAYED threads.
Go to the first, previous, next, last section, table of contents.
