即使在大括号中，也可以在strace中显示完整的参数 [英] Show complete arguments in strace even in curly brackets

问题描述

我知道-s选项应该显示更长的参数，但是它并不总是有效(可能是因为那些花括号意味着数组或嵌套参数?).

I know the -s option should display longer arguments, but it doesn't work always (probably because of those curly brackets meaning array or nested arguments?).

即使运行strace -s1000 my_command之后，该参数仍会被截断:

Even after running strace -s1000 my_command this argument is still truncated:

ioctl(3，SNDCTL_TMR_TEMPO或TCGETA，{B9600 -opost -isig -icanon -echo ...})= 0

ioctl(3, SNDCTL_TMR_TEMPO or TCGETA, {B9600 -opost -isig -icanon -echo ...}) = 0

如何查看完整的参数?

推荐答案

strace参数中有是这样的选项-您应使用 -v 命令行开关. 此外，由于此实用程序的开源特性，您可以通过修补strace

There is such option in the strace parameters - you should use -v command line switch. Furthermore, due to the opensource nature of this great utility, you can disable abbreviation totally by patching the defs.h header in the strace sources:

< #define abbrev(tcp)   ((tcp)->qual_flg & QUAL_ABBREV)
---
> #define abbrev(tcp)   0

我从本地gentoo/usr/portage/distfiles/软件源存储中以这种方式strace-4.9进行了修补.不需要从sourceforge下载最新的strace源.

I've patched that way strace-4.9 from my local gentoo /usr/portage/distfiles/ software sources storage. It doesn't require to download latest strace sources from sourceforge.
