break 普通
tbreak 一次性
rbreak 正则表达式一批断点
基于cpu断点指令，x86 int3机器码0xcc。
替换断点位置的指令
CPU自执行这里触发断点异常。
没有断点数量限制。
基于cpu调试寄存器，dr0～dr7，数量限制。x86可以设定4个断点。数量限制。
不修改代码，在只读内存上设置断点。EEPROM上的代码设置。
有数量限制。
－／＋ 偏移
文件名 ：行号
文件名：函数
-source linename
-function function
-label label
-line number
address location
break * address
file banner
中断在main函数
info funciton useage
显示useage函数地址
*0x88888e4
直接写地址设定断点
显示所有断点
list usage
显示useage函数
当前显示到14行＋2行所以设定在17行
虚拟机设定硬件断点会失败.
(gdb)hbreak hd_ioctl
(gdb) info b

0x053a in v at a.c:4 inf 1
0x053a in v at a.c:4 inf 2
删除所有的断点
sum 删除sum函数入口的所有断点
watchpoint
监视一个表达式，值变化中断。
watch a＊b＋c／d
watch *( int * )
watch fd 监控局部变量fd
注意，x86硬件调试，写操作，执行过这一行，gdb显示下一行，要看上一行。hw watchpoint，在x86平台wachtpoint基于硬件实现，其他平台可能是基于软件实现。 vc6纯软件执行，执行目标速度低。
执行位置超过当前区域，无效监视点会被删除。
访问监视点
读停下来。
读或写停下来。 awatch fd
b hd_ioctl thread
info threads 带＊ 当前线程
繁忙函数解决方案
b hd_ioctl thread 1 if fd & 0
当断点，断了后执行命令
()command 12
()print &fd is %d\n&,fd
()continue
动态ping不修改代码。
tracepoint 远程主机通讯调试，前端stub立刻恢复执行，但会记录下来。
catchpoint
进入子函数内部。单步 step
汇编 stepi
不要进入子函数
跑起来直到3号断点命中
跑起来直到3号断点命中，快捷禁止其他断点。
恢复执行直到函数返回。
调用函数！
gdb 杜撰代码调用函数。
call sum（1，2） &
强制main函数 return。
异常或断点进入调试器。
调试器发起中断，让程序中断下来。ctrl＋C，app收到中断信号，进入调试器。
调试器读区 调试符号。
二进制－调试符号－源码
linux dwarf 存储调试符号信息。gcc
readelf -h filename
里面如果有line location debug标示
readelf -w 导出调试文件
gcc -g 才能输出符号
ubuntu 符号服务器
& /pool/main/&
安装ubunte的linux 内核符号
安装libc符号
dpkg -s /lib/x86_64-linux-gun/libc-2.15.so
dpkg -s libc.so.6
sudo apt-get -c aptproxy.conf install libc6-dbg
libc 调试符号
sudo apt-get install libc6-dbg
gdb 使用file 或 symbol－file 加载符号文件
自动搜索 path 路径
（gdb）i share
* 共享库没调试信息
info vaiables regex 类名／函数名／变量名
内存地址与符号互换
info addriess 函数名
info symbol
(gdb) info address main
Symbol &main& is a function at address 0x400547.
(gdb) info symbol 0x400547
main in section .text of /home/gao/code/a
查看加载的文件内存位置
info files
列出全局变量
info variable
dir 源码路径
常用命令源码
安装系统工具源码和调试
apt-get source coreutils
sudo apt-get install coreutils-dbgsym
gdb /bin/ls
dir ~/src/coreutils-7.4/src
sudo apt-get source libc6-dev
/home/ge/eglibc-2.15
dir 搜索路径
$cdir 编译路径
当前工作路径
查看调试目标
观察寄存器
子函数返回地址
观察函数返回地址
info frame ［address］
info locals
注意，切换栈帧之后可能会发生，本地变量值不准确，因为值存在寄存器中需要小心。
p /f 表达式
表达式要打印位置
N 打印几个单元
u 每个单元大小 b-1byte w-2byte h-4byte
f s字符串i指令格式
x/s 0xfffff
打印字符串
bit 16禁制
0x7fffffffc76c: 0x01
0x7fffffffc774: 0x00
0x7fffffffc77c: 0xff
0x7fffffffc784: 0xff
p *&a[0]@10
a0数组开始的10个元素
disas main
main反汇编代码
这个地址开始的5条汇编指令。
gdb mov 从左往右赋值at&t汇编。
info signals
异常／同步／中断
stop 要不要中断下来看
printf 打印信息
要不要传递给应用程序。
handle 修改规则
handle signal act
handle SIGPIPE
不要中断下来，打印一个信息，网络程序常用
(gdb) handle SIGPIPE nostop
Pass to program Description
Broken pipe
info threads
LWP－light weight process 线程编号。
* gdb当前线程
切换当前线程
打印所有线程
thread apply all bt 针对一群线程的命令避免切换来看。
线程改名字
thread name ［name］
我自己经验 LWP 可以很好的观察线程负载情况。

数组的读区方式不同，按照行读，被cache也是按行连续加载的。
如果按照列读区，那么效率很低，除非cache足够大，而且也要遍历所有的数据，并且cache hash算法也好，实现的硬件还是多路组相联的cache硬件实现。

sqlplus 外面执行正常. tomcat调用老有问题.多调用几次久正常. & 可能是包中的全局变量引起的. & & If so, that's because :
The values of the variables, constants, and cursors that a package declares (in either its specification or body) comprise its package state. If a PL/SQL package declares at least one variable, constant, or cursor, then the package is stateful; otherwise, it is stateless. When you recompile the state is lost:
If the body of an instantiated, stateful package is recompiled (either explicitly, with the "ALTER PACKAGE Statement", or implicitly), the next invocation of a subprogram in the package causes Oracle Database to discard the existing package state and raise the exception ORA-04068.
After PL/SQL raises the exception, a reference to the package causes Oracle Database to re-instantiate the package, which re-initializes it... You can't avoid this if your package has state. I think it's fairly rare to really need a package to be stateful though, so you should revisit anything you have declared in the package, but outside a function or procedure, to see if it's really needed at that level. Since you're on 10g though, that includes constants, not just variables and cursors.
But the last paragraph from the quoted documentation means that the next time you reference the package in the same session, you won't get the error and it will work as normal (until you recompile again).
& existing state of packages has been discarded means, that your Package had some sort of state.
This is caused by a global variable (or constant) stored in your Package Body.
Since the package has already been used in your session, Oracle assumes that this state is relevant for you. Some of these variables might have different values now, and when you recompile the Body, the values are reset.
This exception is thrown, so that your clients know that they can't rely on those variables any more.
You could try to remove all global variables and constants from the Package Body, or close your session and reconnect before calling the package again.

RiskUnit0001.o: relocation R_X86_64_32 against `a local symbol' can not be used when ma recompile with -fPIC
obj/Debug/src/RiskUnit0001/RiskUnit0001.o: could not read symbols: Bad value
为什么需要
解决办法编译器已经提示了：recompile with -fPIC
但是我们应该重新编译谁带上这个参数呢？经过我几番折腾，发现如下情况：
1、编译.o文件的时候，没有加参数-fPIC，这问题个在gcc version 3.4.6版本没有发生，可能那个编译器默认都给加上吧。
2、当前程序中有用到某个静态库，那个静态库编译.o文件的时候没有加上-fPIC（静态库其实就是.o文件打包）。补充一点：我发现手写Makefile时即使不加-fPIC也没有这个问题，这一点很郁闷，这个只在用automake工具编译出.a文件时才出现过。
知道原因了，解决办法自然有了，保证你编译.o文件的时候，都加上-fPIC，这样你才能编译出动态库来。

一般来说，如果你不是MFC工程，需要引用HANDLE的话，
最好自己将其类型改为void*,比如，你本来变量的类型为HANDLE，
你把它改为void*就可以了。

发生在析够函数中,   vs2010 debug 模式 .
CriticalSection::~CriticalSection(void){
    DeleteCriticalSection(&m_CritSect);  }
我开始推测,必须退出section才能delete ?
    InitializeCriticalSection(&m_CritSect);         EnterCriticalSection(&m_CritSect);      DeleteCriticalSection(&m_CritSect);      实际上这样退出是可以的.
问题在哪里? 
一个回调处理函数类注册到另外一个线程里面.另外一个线程一直有消息推送或者调用其内部函数.
       aa-&release(); //之前没有这句话 ,内部aa 线程一直在运行 ,可能是排在析构 (DeleteCriticalSection)之后或者之前,损坏了这个变量 m_CritSect
这里开始调用  DeleteCriticalSection(&m_CritSect);   并且报错了.
别的项目里面拿来的 .h .cpp 
因为本项目未使用预编译头.
但是预编译头这个头文件存在,里面东西很多.
导致很多宏  或者 常量重复定义.
定义成标准头
int main(int argc, char *argv[])
int main() {
PWSTR cmdLine = GetCommandLineW();
PWSTR *argv = CommandLineToArgvW(cmdLine, &argc);
//参数使用
if (argc==3)
if (strcmp(argv[0], &-e&)==0)
iMode = 1;
else if (strcmp(argv[0], &-d&)==0)
sInput=argv[1];
sOutput=argv[2];
_tmain  Unicode下就是wmain
否则就是main
我老是搞错.
Boy  g_
使用全局变量
Collection.h
#include “boy.h”
extern Boy g_
似乎更优雅的方式
#ifdef  _BOY__HH__
extern  Boy  g_
错误方式:    定义宏根本解决不了这个问题
#pragma once
#ifndef _BOY__HH__
#define _BOY__HH__
class  boy

***************
测试模拟工具发送大数据量消息时，发现时而发送成功，时而失败。追踪代码发现，抛出的是一个错误码为10035的socket错误。上网查资料发现这个错误码描述是Service temporarily unavailable.也就是说有可能send的时候遇到socket缓冲区满，无法写入，引起发送失败。
& 如果是这样的话，那么这就是一个常规的异常情况，需要对它进行处理，而不是异常退出。
& 最后代码改成这个样子，send然后分析返回结果，如果错误，且错误码为10035，那么就重发，直到发成功时，break。
& 目前尚不知道，这样改的副作用有没有，反正现在问题暂时解决鸟
***********************************
& Winsock connect函数返回错误，使用WSAGetLastError得到，是什么原因MSDN注释：WSAEWOULDBLOCK10035Resource temporarily unavailable. This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. It is a nonfatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established.WSAEALREADY10037Operation already in progress. An operation was attempted on a nonblocking socket with an operation already in progress—that is, calling connect a second time on a nonblocking socket that is already connecting, or canceling an asynchronous request (WSAAsyncGetXbyY) that has already been canceled or completed.网络翻译：10035—WSAEWOULDBLOCK资源暂时不可用。对非锁定套接字来说，如果请求操作不能立即执行的话，通常会返回这个错误。比如说，在一个非暂停套接字上调用 connect，就会返回这个错误。因为连接请求不能立即执行。10037—WSAEALREADY操作已完成。一般来说，在非锁定套接字上尝试已处于进程中的操作时，会产生这个错误。比如，在一个已处于连接进程的非锁定套接字上，再一次调用 connect 或 WSAConnect。另外，服务提供者处于执行回调函数（针对支持回调例程的 Winsock函数）的进程中时，也会出现这个错误。我描述下问题：使用socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);创建一个TCP/IP套接字，然后创建一个线程，不停地用connect函数进行链接，直到链接成功，才退出线程，问题来了，connect函数它有时候返回成功，有时候又返回错误，用WSAGetLastError得到享受10035， 10037这两种错误值，我将错误值打印出来，结果是：1，1，1，10037.......，10037。
