PTP无法连接到调试器 [英] PTP fails to connect to debugger

问题描述

我正在撰写此电子邮件以寻求帮助，为基于openMPI的应用程序设置调试环境。目前，我正在努力解决阻碍我继续工作的问题。这个问题与在stackoverflow上发布的内容非常相似（参见：链接）。其症状是调试过程挂起，并行调试视角显示操作正在进行...消息。它是由错误引起的，即无法连接到调试器。与此同时，错误消息getaddrinfo：Undefined error：0也显示在调试控制台中。

我在互联网上进行了一些搜索，发现了解决问题的指令（请参阅：链接）。我已经验证过：

• 启动脚本可以工作：非调试启动正常工作


• 正确sdm进程的数量


• 可以创建路由文件
  

但我无法找到一个sdm进程的参数-master。

目前，我使用以下软件组件和指定版本：

• 并行工具平台，包括PTP并行语言开发工具等（9.0.1.201509091505）

ptp -sdm-9.0.0（org.eclipse.ptp.macosx_9.0.0.201506101404）


• GNU gdb（7.10）

我使用的操作系统是OS X Yosemite（10.10.5）。我在本地机器上运行应用程序。

有没有人遇到类似的问题，并且知道如何解决它？我很感激任何提示或帮助。

解决方案

我找到了可能是原因的东西。我从shell终端运行Eclipse，以便可以看到更多的文本/日志输出。然后在 Eclipse - >首选项 - >并行工具 - >并行语言开发工具下启用显示命令输出，这就是我在父shell中看到的在Eclipse中）：

 清理：rm -f routing_file 
 submit-interactive-debug：ac5df46b-c4f2-438a- 9565-9b26818e880d：perl /Users/<username>/.eclipsesettings/rms/MPICH2/start_debug_job.pl mpiexec -np 4 /Users/<username>/.eclipsesettings/sdm --port = 51347 --host = localhost  - -debugger = gdb-mi 
 SDM Master：/Users/<username>/.eclipsesettings/sdm -master --port = 51347 --host = localhost --debugger = gdb-mi 
 SDM Master ：sdm [--debugger = value] [--debugger_path = path] 
 SDM Master：[--proxy = proxy] 
 SDM Master：[--host = host_name] [--port = port ] 
 SDM Master：[--master] 
 SDM Master：[--server = rank] 
 SDM Master：[--generate_routes = list] 
 SDM Master：[ - -routing_file =路径] 
 SDM主文件：[--debug [= 1 evel]] 
  

这表明 sdm 是无效的，实际上我发现它正在接收 -master 而不是 - master 标志。





我尝试在 / Users /< username> /。eclipsesettings / rms / MPICH2 / start_debug_job.pl打开perl脚本。 code>但它在那里是正确的，并且所做的任何更改只出现在Eclipse的输出控制台中，而不是我从eclipse运行eclipse的父shell。某处 sdm 正在发送错误的 -master 标志，也许这是问题的一部分。不幸的是，除此之外，我没有答案。



更新：我提交了一个错误报告： https://bugs.eclipse.org/bugs/show_bug.cgi?id=521975

I am writing this email to ask for help in setting up a debugging environment for openMPI-based applications. Currently, I am struggling with a problem that is hampering me from continuing the work. The problem is very similar to what has been posted on the stackoverflow (See: Link). Its symptom is that the debugging process hangs and the parallel debugging perspective shows a "Operation in progress…" message. It is caused by an error, namely "Cannot connect to debugger". Meanwhile, an error message "getaddrinfo: Undefined error: 0" also appear in the debugging console.

I did some search on the internet and I found an instruction for trouble shooting (See: Link). I already verified that:

• Launch script could work: non-debug launch works fine
• Correct number of "sdm" processes
• Routing file can be created

But I could not find one "sdm" process with argument "—master".

Currently, I use the following software components with indicated versions:

• Parallel Tools Platform including PTP Parallel Language Development Tools, etc. (9.0.1.201509091505)

• ptp-sdm-9.0.0 (org.eclipse.ptp.macosx_9.0.0.201506101404)

• GNU gdb (7.10)

The OS I am using is OS X Yosemite (10.10.5). And I run application on the local machine.

Did anyone encounter the similar problem and happen to know how to fix it? I would appreciate any hint or help from you.

解决方案

I found something that might be the cause. I ran Eclipse from a shell terminal so that I could see more text/log output. Then under Eclipse -> Preference -> Parallel Tools -> Parallel Language Development Tools I enabled the Show output from commands, and this is what I see in the parent shell (not within Eclipse):

Cleanup: rm -f routing_file
submit-interactive-debug: ac5df46b-c4f2-438a-9565-9b26818e880d: perl /Users/<username>/.eclipsesettings/rms/MPICH2/start_debug_job.pl mpiexec -np 4 /Users/<username>/.eclipsesettings/sdm --port=51347 --host=localhost --debugger=gdb-mi
SDM Master: /Users/<username>/.eclipsesettings/sdm -master --port=51347 --host=localhost --debugger=gdb-mi
SDM Master: sdm [--debugger=value] [--debugger_path=path]
SDM Master:     [--proxy=proxy]
SDM Master:     [--host=host_name] [--port=port]
SDM Master:      [--master]
SDM Master:     [--server=rank]
SDM Master:     [--generate_routes=list]
SDM Master:     [--routing_file=path]
SDM Master:     [--debug[=level]]

This suggests that one of the argument inputs to sdm is invalid, and indeed I see that it is receiving -master instead of --master flag.

I tried to open the perl script at /Users/<username>/.eclipsesettings/rms/MPICH2/start_debug_job.pl but it's correct there, and any changes made only appear within Eclipse's output console, not the parent shell I ran eclipse from. Somewhere sdm is being sent the wrong -master flag, and maybe that is part of the problem. Unfortunately I don't have an answer beyond that.

Update: I have submitted a bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=521975
