git svn - cygwin 下的错误

coder 2023-06-24 原文

我有 cygwin 和 git。我正在尝试使用 git 提交到 svn - git svn dcommit。但它因奇怪的错误而失败:

$ git svn dcommit
      4 [main] perl 5536 C:\cygwin\bin\perl.exe: *** fatal error - unable to remap \\?\C:\cygwin\lib\perl5\5.10\i686-cygwin\auto\List\Util\Util.dll to same address as parent: 0xA20000 != 0xB40000
Stack trace:

End of stack trace

我该如何解决？谢谢。

附言 我的系统是 windows 7 64 位。

更新

reabase 有所帮助。但我必须在执行 rebase 后重新启动。

最佳答案

您是否尝试过 rebaseall 喜欢described here ？

When you are working with Cygwin, sometimes you will get an error like this

unable to remap some.dll to same address as parent someapp 4292 fork:
child 3964 - died waiting for dll loading, errno 11"

Then you would need to run rebaseall.
In order to run it, close all your Cygwin windows, Execute <cygwin_home>\bin\ash.exe. It will open a new console window. Execute rebaseall there.
Once it has completed, you can go back to running Cygwin again without any issues :-)

OP gor报告说他必须重新启动才能制作 rebaseall工作。
Dan Moulding评论中提到:

I'll just add that closing all Cygwin windows may not be sufficient.
You should make sure all Cygwin processes and services are terminated and/or stopped (ps -a from ash should show nothing but ash and ps) before rebasing.

rsenna报道 in the comments :

For an explanation of why this is needed, see fatal error - unable to remap to same address as parent: Cygwin, Ruby on Rails, System calls

So what actually is happening?
Well, in this case, the problem was a result of the way Windows manages its .dll's.

Windows uses ASLR (address space layout randomization) to manage its .dll's. It loads your dll's into different areas of memory every time you boot your computer.
If this gets out of whack then the next time you look for that .dll - you can crash your system. Or if you look in the wrong place, you can crash your system.
So how can this system get out of whack? Well, running your cygwin setup program can affect record keeping, especially if the ASLR has changed but Cygwin is holding on to an older copy (this can happen when setup doesn't complete).

ASLR is a great defense against malware or hackers. Hackers can't constantly try new addresses for your .dll's without crashing your system.
