在Ruby解释器出现段错误之后，是否有可能从corefile获取Ruby回溯？ [英] After the Ruby interpreter segfaults, is it possible to get the Ruby backtrace from the corefile?
本文介绍了在Ruby解释器出现段错误之后，是否有可能从corefile获取Ruby回溯？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在生成一个XML文档时，我得到了一个奇怪的segfault：
$ b $ $ p $ / railsroot / vendor / isolated / ruby-1.8 / gems / libxml-ruby-1.1.2 / lib / libxml / node.rb：123：[BUG]分割错误
ruby 1.8.7（2011-02-18 patchlevel 334） [x86_64-linux]，MBARI 0x6770，Ruby Enterprise Edition 2011.03
中止
更新1：这段segfaults也在rubilla（MRI）下面。
我打开了corefiles并查看了backtrace在gdb中（请参阅问题的结尾）。我可以看到解释器崩溃的位置，Google搜索会导致很多有希望的结果。除了解释器回溯之外，我想看到的是Ruby代码本身的回溯（即从解释器的角度来看回溯）。
我希望在gdb中加载内核将允许我调用一些解释器函数来打印解释代码的堆栈。
任何想法？
这是核心和回溯，好奇：
：foo @ bar; ulimit -c unlimited
：foo @ bar; RAILS_ENV = production ./script/runner script / feeds / batchfeed.rb --config config / feeds / $ feed.yml --timer /tmp/$feed.timer --gzip --output /tmp/$feed.xml。 gz

当您看到如下所示的内容：

你可以弄清楚Ruby代码在做什么。我有一篇关于这方面的博客文章：
http://seclib.blogspot.com/2011/08/inspect-ruby-process-from-gdb.html
Note: I'm using a segfault that I encountered whilst using the libxml-ruby gem to illustrate the question, but I've since fixed my problem with said gem. What this question is really about is viewing the Ruby backtrace (i.e. the same thing the interpreter prints when Ruby code fails to handle an exception) from gdb with a corefile the interpreter itself encounters a segmentation fault.
I'm getting an odd segfault while generating an XML document, of all things:
/railsroot/vendor/isolated/ruby-1.8/gems/libxml-ruby-1.1.2/lib/libxml/node.rb:123: [BUG] Segmentation fault
ruby 1.8.7 (2011-02-18 patchlevel 334) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2011.03
Aborted
Update 1: This segfaults under vanilla Ruby (MRI) as well.
I've turned on corefiles and taken a look at the backtrace in gdb (see the end of the question). I can see where the interpreter crashing, and Googling for this leads to lots of promising results. What I'd like to see, in addition to the interpreter backtrace, is the backtrace in the Ruby code itself (i.e. the backtrace from the interpreter's point of view).
I'm hoping that loading the core in gdb will allow me to call some interpreter function that prints out the stack of the interpreted code.
Any ideas?
Here's the core and backtrace, for the curious:
: foo@bar; ulimit -c unlimited
: foo@bar; RAILS_ENV=production ./script/runner script/feeds/batchfeed.rb --config config/feeds/$feed.yml --timer /tmp/$feed.timer --gzip --output /tmp/$feed.xml.gz

解决方案
When you see something like this: rb_call (klass=37665480, recv=132610480, mid=104367, ...
You can figure out what the ruby code is doing. I have a blog article on that:

这篇关于在Ruby解释器出现段错误之后，是否有可能从corefile获取Ruby回溯？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
