5. Waits

Waits

目前大部分Web应用都使用的是AJAX技术。当一个页面被加载到浏览器时，这个页面的元素可能在不同时间段进行加载。 如果元素不存在与DOM中，将很难被定位到并将会报出

ElementNotVisibleException 异常。我们可以使用waits来解决这个问题。Waiting 操作执行之间提供了时间的间隔。

Selenium Webdriver 提供了两种 waits:implicit & explicit.

Explicit Waits（显示等待）

定义一个等待的条件，当到达这个条件后，结束等待。

Expected Conditions

  • title_is
  • title_contains
  • presence_of_element_located
  • visibility_of_element_located
  • visibility_of
  • presence_of_all_elements_located
  • text_to_be_present_in_element
  • text_to_be_present_in_element_value
  • frame_to_be_available_and_switch_to_it
  • invisibility_of_element_located
  • element_to_be_clickable - it is Displayed and Enabled.
  • staleness_of
  • element_to_be_selected
  • element_located_to_be_selected
  • element_selection_state_to_be
  • element_located_selection_state_to_be
  • alert_is_present

Implicit Waits(隐式等待)

定义一个等待的时间。默认值为0s.

Innodb引擎 long semaphore waits

上一篇介绍了因为子表过多,导致innodb crash的情况,但crash的原因是long semaphore waits.long semaphore waits又为何物? 背景:Innodb使用了mutex和rw_lock来保护内存数据结构,同步的机制要么是互斥,要么是读写阻塞的模式, Innode认为mutex和rw_lock hold的时间足够短,所以,如果有线程wait mutex或者rw_lock时间过长,那么 很可能是程序有bug,所以就会异常主动crash. 关于innodb的锁

Selenium Explicit Waits

5.1. Explicit Waits An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is time.sleep(), which sets the condition to an exact time period to wait. There are some

如今,大多数的Web应用程序使用AJAX技术.当页面加载到浏览器,页面中的元素也许在不同的时间间隔内加载.这使得元素很难定位,如果在DOM中的元素没有呈现,它将抛出ElementNotVisibleException异常.使用waits,我们可以解决这个问题. Selenium WebDriver 提供两种类型的waits -- 隐式和显式.显式的wait使webdriver等待发生之前,继续执行一定的条件.一个隐式的wait使webdriver DOM在一定时间后,试图定位元素. Explic

buffer cache —— buffer busy waits/read by other session

oracle提供非常精确.有效的row level lock机制,多个用户同时修改数据时,为了保护数据,以块为单位挂起锁的情况不会发生.但这不太正确.以块为单位的锁虽然不存在,但正因为oracle I/O以块为单位组成,所以块单位锁是必要的.假设row1.row2两个行位于同一个块内,两名用户(用户1.用户2)各自对row1.row2执行update,逻辑上两个被更新行之间不存在需要相互保护的数据.因为oracle提供row level lock机制,所以修改互相不用的行完全不成问题.但是若两个
