一些ADPlus配置文件的收集
定断点在方法ntdll!RtlEnterCriticalSection 上, 一旦执行到这个方法, 就写log, 记录callstack, 并且打印寄存器的值. 定断点在地址77f5b380 上, 动作同前一个.

设置条件断点, 发生异常的时候, 对esp进行计算后判断, 条件不满足时, 如何如何, 满足时抓dump.
<ADPlus>
<!--
Configuring ADPlus to create a conditional breakpoint
When using j we need to include the "g" command into each branch due to its special syntax
with j everything after the two branches is ignored
For this reason we need to use VOID in ReturnAction
Note - when using j commands with breakpoints it may be more convenient to use gc instead of g
if you plan to do live debug; see documentation for gc in debugger.chm

针对.net的某种特定类型的异常, 抓dump.
<ADPlus>
<!-- Configuring ADPlus for custom actions on a given CLR exception -->
<!-- First we load sos extension -->
<!-- Next we use the !cce command to check if the exception is the one we are looking for -->
<!-- Next we use a j command on $t1 to do what we want -->
<!-- Replace UnhandledException_Console.MyCustomException below with the name of the exception you are looking for -->
<!-- You need to put the GN in the two branches of the j command and use VOID in the ReturnACtion1 tag -->
<Exceptions>
<Config>
<!-- This is for the CLR exception -->
<Code> clr </Code>
<Actions1> Log </Actions1>
<CustomActions1> !cce UnhandledException_Console.MyCustomException 1; j ($t1 = 1) '.dump /ma /u c:\Dumps\MyCustom.dmp;gn' ; 'gn' </CustomActions1>
<ReturnAction1> VOID </ReturnAction1>
</Config>
</Exceptions>
</ADPlus>
先创建一个exception, 利用这个exception的exception code作为标识, 抓dump.
<ADPlus>
<!--Configuring ADPlus to monitor a custom exception -->
<Exceptions>
<!-- Creating the exception -->
<NewException>
<Code> c000008f </Code>
<Name> CustomExc_c000008f </Name>
</NewException>
<!-- Configuring the exception. Here we configure it to create a full dump and a log on first chance -->
<Config>
<Code> c000008f </Code>
<Actions1> FullDump;Log </Actions1>
</Config>
</Exceptions>
</ADPlus>
转在SPException异常抛出的时候抓取dump文件.
<ADPlus>
<PreCommands>
<Cmd> .loadby sos mscorwks </Cmd>
</PreCommands>
<PostCommands>
<Cmd> sxe -c "!soe Microsoft.SharePoint.SPException 1;.if(@$t1==0) {g} .else {.dump /u /ma d:\\dumps\\dump1.dmp;g}" clr </Cmd>
</PostCommands>
</ADPlus>
异常发生的时候, 打印异常, 和调用栈, 然后继续.
<ADPlus>
<PreCommands>
<Cmd> .loadby sos mscorwks </Cmd>
</PreCommands>
<PostCommands>
<Cmd> .logopen d:\dumps\debug.log;sxe -c "!pe;!clrstack;g" clr </Cmd>
</PostCommands>
</ADPlus>
非crash, 进程正常退出的时候抓取dump.
<ADPlus>
<Breakpoints>
<NewBP>
<Address> Kernel32!TerminateProcess;Kernel32!ExitProcess</Address>
<Type> BP </Type>
<Actions> FullDump;Stacks;Log </Actions>
<ReturnAction> G </ReturnAction>
</NewBP>
</Breakpoints>
</ADPlus>
抓First Chance的Access Violation的dump.
<ADPlus>
<Exceptions>
<Config>
<!-- Break on CLR exception type -->
<Code> AV </Code>
<Actions1> Log;Stack;FullDump </Actions1>
<Actions2> Log;Stack;FullDump </Actions2>
<ReturnAction1> gn </ReturnAction1>
</Config>
</Exceptions>
</ADPlus>
拿到System.Web.RequestTimeoutManager.CancelTimedOutRequests方法的执行地址, 断点之, 断点入则抓dump. 这里值得注意的是使用.foreach命令跳过一些字符串拿到执行地址的技巧.

参照上面的例子, 我自己写了一个. 在System.Xml.Serialization.XmlSerializer..ctor 的众多版本中, 选出一个自己想要的, 断之, 抓dump. 注意这里的/ps 100, 用于跳过找到目标地址后面的输出, 100就是个较大的数, 只要大过name2ee命令输出的字符串数就可以了.
