关于mutt发送中文附件，foxmail，outlook接受不到的问题
经常在linux下工作，所有日常事务也是在linux处理，邮件处理自然也不例外，我这里环境是arch+mutt。带英文附件名的邮件使用mutt发送没有一点问题，中文附件名的邮件就悲剧了，附件在foxmail中不被识别，在outlook和DreamMail里是被篡改的名字类似“xxxxxx.MSWORD”,当然你强制用word打开还是没有问题的，但是始终是不爽！所以今天折腾了半天这个问题！
google了n多帖子，都基本是说设置
set rfc2047_parameters=yes
但是经过测试，这个只能使本地接收到的附件显示为中文附件名！要使自己发送的中文附件名在win下的客户端显示正常，这个不得行！
又google了n多帖子，就出现了最终的解决方法：
set create_rfc2047_parameters=yes
该设置需要在mutt源码中打patch，named patch-1.5.10.tt.create_rfc2047_params.1 点击下载
再到mutt主页上下在最近的mutt包 named mutt-1.5.21.tar.gz猛击下载
解压mutt-1.5.21.tar.gz和patch，解压出的patch放到mutt-1.5.21目录下，在该目录执行
patch -Np1 -i patch-1.5.10.tt.create_rfc2047_params.1
接着再执行
./configure &make &sudo make install
接个就用吧！mutt发送中文附件邮件，在foxmail中显示就ok了！
PS：这里要说一点，在ubuntu下，发送中文附件是没问题，但是用mutt中中文是乱码！这个可能与系统设置有关系，暂时没有处理！
在AWESOME上加入天气使用googleAPI字体weather.ttf

lua通过google的天气api获得天气
lua获取天气
昨天写了一个lua的天气脚本，主要是获取http://qq.ip138.com天气信息，基本功能都已实现，但是唯一不足之处，就是不能显示当前的天气及气温。所以今天在网上找了下这方面的资料，发现google天气API获得满足了这个需求，于是就有折腾了下。google API特点：当天气和气温是实时的，明后几天是温度区间。
上代码先
#!/usr/bin/lua5.1
local http = require("socket.http")
------------------------regex-------------------------
function get_weather(con)
local s = "<current_conditions>.*<\/forecast_conditions>"
local i ,j = string.sub(con, string.find(con,s))
local s = "\"[a-z0-9A-Z%s:%%]*\""
local info
for word in string.gmatch(i, s) do
info = tostring(info).."\t"..tostring(word)
end
local i, j = string.gsub(info, "\"","")
local l = split(i,"\t")
return l
end
------------------------split-------------------------
function split(string, spt)
local find_index = 1
local spt_index = 1
local spt_arr = {}
while true do
local find_end = string.find(string, spt, find_index)
if not find_end then
spt_arr[spt_index] = string.sub(string, find_index, string.len(string))
break
end
spt_arr[spt_index] = string.sub(string, find_index, find_end - 1)
find_index = find_end + string.len(spt)
spt_index = spt_index + 1
end
return spt_arr
end
------------------------main-------------------------
function main()
local url = "http://www.google.com/ig/api?weather=chengdu"
local con, ret = http.request(url)
if con == nil then
print ("nil")
else
local l = get_weather(con)
print(l[2],l[3],l[4],l[5],l[6])
end
end
main()
数组中包含了最近几天的天气信息，没有像昨天的那个脚本那样进行分类，这是一个遗憾，不过下标的位置是固定的，这也方便了取值！
lua 获得天气信息
其实开始是想做在awesome statbar显示天气的（字体图标的那种），现在终端获得天气已经写好！
明天再着手搞字体的转换问题!
#!/usr/bin/lua5.1
local http = require("socket.http")
------------------------split-------------------------
function get_weather(con)
local s = "<b>.*<br\/><br\/>"
local i ,j = string.sub(con, string.find(con,s))
local i, n = string.gsub(i, "<br\/><br\/><b>","\n")
local i, j = string.gsub(i, "<br\/>","\t")
local i, j = string.gsub(i, "<\/b>","")
local i, j = string.gsub(i, "<b>","")
local i, j = string.gsub(i, "℃","°C")
local i, j = string.gsub(i, "～","-")
-- print(i,n+1)--所有天气
local list_n = split(i, "\n")
local list_t = split(list_n[1],"\t")
return list_t
end
------------------------split-------------------------
function split(string, spt)
local find_index = 1
local spt_index = 1
local spt_arr = {}
while true do
local find_end = string.find(string, spt, find_index)
if not find_end then
spt_arr[spt_index] = string.sub(string, find_index, string.len(string))
break
end
spt_arr[spt_index] = string.sub(string, find_index, find_end - 1)
find_index = find_end + string.len(spt)
spt_index = spt_index + 1
end
return spt_arr
end
------------------------main-------------------------
function main()
local url = "http://qq.ip138.com/weather/sichuan/chengdu.wml"
local con, ret = http.request(url)
if con == nil then
print ("nil")
else
-- print (con)
local list_t = get_weather(con)
print ('今天天气:',list_t[1],list_t[2],list_t[3],list_t[4])
end
end
main()
关于awesome设置时间格式的问题！
支持版本
awesome 3.4.5 以上
背景
今天突然想修改下awesome的系统时间显示，google了下，基本都是手册上所说！
格式%a %b %d, %H:%M 为awesome默认配置（ 在/etc/xdg/awesome/rc.lua中并没有这么书写而是
mytextclock = awful.widget.textclock({ align = "right" })
后面的格式和时间刷新省略了，默认刷新是60秒），看到%a %b %d, %H:%M，让我想到了系统命令date的参数，之前曾经处理过类似的格式显示，所以这次直接man date，果然，其中的格式控制和上面完全吻合，猜想lua脚本中使用日期格式控制应该是调用系统命令date的格式控制。
具体代码
了解到之后就在rc.lua中修改
mytextclock = awful.widget.textclock({ align = "right" },"%x %X",1)
正如预期结果一样，时间显示为（01/26/11 17:13:48）！看来lua语言还是调用底层的系统函数来实现日期时间的格式的。（lua也在偷懒）
statfs获得硬盘使用情况 模拟linux命令 df （2011.3.24修正）
statfs:
结构：
#include <sys/vfs.h> /* 或者 <sys/statfs.h> */
int statfs(const char *path, struct statfs *buf);
int fstatfs(int fd, struct statfs *buf);
参数：
`path`: 位于需要查询信息的文件系统的文件路径名。
`fd`： 位于需要查询信息的文件系统的文件描述词。
`buf`：以下结构体的指针变量，用于储存文件系统相关的信息
struct statfs {
long f_type; /* 文件系统类型 */
long f_bsize; /* 经过优化的传输块大小 */
long f_blocks; /* 文件系统数据块总数 */
long f_bfree; /* 可用块数 */
long f_bavail; /* 非超级用户可获取的块数 */
long f_files; /* 文件结点总数 */
long f_ffree; /* 可用文件结点数 */
fsid_t f_fsid; /* 文件系统标识 */
long f_namelen; /* 文件名的最大长度 */
};
statfs结构中可用空间块数有两种f_bfree和 f_bavail，前者是硬盘所有剩余空间，后者为非root用户剩余空间，ext3文件系统给root用户分有5%的独享空间，所以这里是不同的地方。这里要强调的是每块的大小一般是4K。因此，要实现与df结果一致的就得在获得块数上乘以4，这样已用、可用、总块数就可以实现。如果还要实现百分比一致，那么要注意的是，df命令获得是整数百分比，没有小数，这里使用的进一法，而不是四舍五入法。所以在程序里直接+1取整。
下面是实现的一个例子：（home目录为一个独立分区）
#include <stdio.h>
#include <sys/vfs.h>
int main()
{
struct statfs sfs;
int i = statfs("/home", &sfs);
int percent = (sfs.f_blocks - sfs.f_bfree ) * 100 / (sfs.f_blocks - sfs.f_bfree + sfs.f_bavail) + 1;
printf("/dev/sda11 %ld %ld %ld %d%% /home\n",
4*sfs. f_blocks, 4*(sfs.f_blocks - sfs.f_bfree), 4*sfs.f_bavail, percent);
system("df /home ");
return 0;
}
执行结果:
leave@LEAVE:~/test$ gcc -o df df.c
leave@LEAVE:~/test$ ./df
/dev/sda11 42773008 540356 40059864 2% /home

使用 memleak 检查和调试内存泄漏
memleak
使用范围：
小型的嵌入式应用中经常会出现许多内存问题，很多情况下难以定位问题出现在哪里。
我在 sourceforge上找了些检测 C 内存泄漏的工具，感觉比较易用的是 memleak，下面就来简要介绍一下它的使用。
用法：
下载得到的 memleak 压缩包大小不到 15 kB，解压后只有两个文件：memleak.c 和 memleak.h。在使用过程中只需要包含头文件 memleak.h 就可以使用 memleak 提供的几个易用而有效的内存检测函数了。
memleak 的原理是利用 C 语言的宏调用来替代原有的函数调用，比如我们在代码中调用 malloc(s)，实际是调用了：dbg_malloc(s)，这个宏定义在 memleak.h 中给出：
#define malloc(s) (FILE_LINE, dbg_malloc(s))
memleak 维护了一个链表，在这个链表中保存着程序中对内存函数调用的记录，这些函数包括：malloc、calloc、realloc、free。每次调用这些函数时，就会更新这个链表。
有 了这个表，我们就可以在适当的位置调用 memleak 提供的函数，显示一些重要的信息，包括 malloc、calloc、realloc、free调用的次数，申请及分配的内存数，调用的文件和位置等等，信息非常详细。有了这些功能，我们就很容 易定位内存使用的错误源。
由于 memleak 在某些交叉编译器下不能正常编译通过，这里我将 memleak.c 中的结构体 struct head 修改如下：
struct head
{
struct head *addr;
size_t size;
char *file;
unsigned line;
/* two addresses took the same space as an address and an integer on many archs => usable */
union lf {
struct { struct head*prev, *next; } list;
struct { char *file; unsigned line; } free;
} u;
};
memleak.c 文件中其它调用到 head 中共用体 u 的地方也要做相应的修改。
修改后的文件可以点击这里下载。
memleak 提供了以下几个函数接口：
extern void dbg_init(int history_length);
extern int dbg_check_addr(char *msg, void *ptr, int opt);
extern void dbg_mem_stat(void);
extern void dbg_zero_stat(void);
extern void dbg_abort(char *msg);
extern void dbg_heap_dump(char *keyword);
extern void dbg_history_dump(char *keyword);
extern void dbg_catch_sigsegv(void);
详细的介绍请查看 memleak.c 头部的注释或查看源代码理解。
下面举个简单的例子：
#include "memleak.h"
int main(void)
{
char * s, * t;
dbg_init(10);
s = (char *)malloc(100); // 申请 100 bytes
t = (char *)malloc(11); // 再申请 11 bytes
free(s); // 释放 100 bytes
s = (char *)malloc(80); // 重新申请 80 bytes
dbg_heap_dump(""); // 显示调用栈
dbg_mem_stat(); // 显示调用统计
free(t); // 释放 11 bytes
free(s); // 释放 80 bytes
dbg_mem_stat(); // 再次显示调用统计
return 0;
}
编辑后保存为 test.c，与 memleak.c 和 memleak.h 放于同一目录下。
然后编写一 Makefile：
CC = gcc
EXEC = test
CSRC = test.c memleak.c
OBJS = $(patsubst %.c,%.o, $(CSRC))
all: $(EXEC)
$(EXEC): $(OBJS)
$(CC) $(OBJS) $(LDFLAGS) $(LDLIBS) -o $@
$(OBJS): %.o : %.c
$(CC) $(CFLAGS) -c $< -o $@
clean:
-rm -f $(EXEC) *.elf *.gdb *.o
也保存于同一目录，在该目录下 make 编译，执行 ./test 后输出如下：
\***** test.c:14: heap dump start
(alloc: test.c:11 size: 11)
(alloc: test.c:13 size: 80)
\***** test.c:14: heap dump end
test.c:15: m: 3, c: 0, r: 0, f: 1, mem: 91
test.c:18: m: 3, c: 0, r: 0, f: 3, mem: 0
怎么样，很简单吧？
memleak 中还有一个函数 dbg_catch_sigsegv(void)，可以绑定系统出现 SIGSEGV 信号时的处理函数，我们可以通过修改 memleak.c 中的 sigsegv_handler，自定义这个 SIGSEGV 信号处理函数。不知道 uClinux 下的 SIGSEGV 信号是否也存在，有的话调试一些内存问题就更容易了。
最后从网上摘来一段 SIGSEGV 的介绍：
SIGSEGV --- Segment Fault. The possible cases of your encountering this error are:
1.buffer overflow --- usually caused by a pointer reference out of range.
2.stack overflow --- please keep in mind that the default stack size is 8192K.
3.illegal file access --- file operations are forbidden on our judge system.
