git-svn --ignore-paths [英] git-svn --ignore-paths

问题描述

现在，我正努力使用--ignore-paths选项到git-svn几个小时，试图从大型存储库中只读取某些标签。

我想在dev上开始读取，看起来像

 > svn ls http://192.168.0.2/svn/repo/corporation/dev 
 branches / 
 tags / 
 trunk / 
  

$ b

完整标记集的存储库目录列表如下所示：

 > svn ls http://192.168.0.2/svn/repo/corporation/dev/tags 
 Acme-4.x / 
 Acme-5.0 / 
 Acme-5.1 / 
 Acme -5.2 / 
 Acme-5.3 / 
 Acme-5.4 / 
 Acme-5.5 / 
 Acme-5.6 / 
 Acme-5.7 / 
 Acme-5.8 / 
 Acme-5.9 / 
  

我想在Acme-5.5之前忽略所有的标签。 / b>

我尝试初始化并获取：

 > git svn init http://192.168.0.2/svn/repo/corporation/dev 
> git config svn.authorsfile ../users.txt 
> git svn fetch --ignore-paths =Acme-4.x | Acme-5.0 | Acme-5.1 | Acme-5.2 | Acme-5.3 | Acme-5.4
  

不幸的是，我仍然看到在Acme-4.x标记中发生了取值。这些提取在控制台上通过诸如

 一个ACME4.4 / source / database / mssql / components / functions /vssver.scc 
  

我试过了一堆正则表达式的变体，包括标签我想忽略，这一两个小时后变成了完全正则表达式的颠簸和绝望。我为git-svn-init提供了--ignore-paths选项，都无济于事。

有人会评论正则表达式的原因不要取消在ignores-regex中指定的路径。

谢谢。

我今天遇到同样的问题：我的正则表达式根本无法匹配...
请确保您知道目标路径的实际外观如何。我正在对提供给我的正则表达式的路径结构做出不正确的假设。

要找出路径的样子， make git- svn会输出到控制台的每个路径，因为它会测试它们：

注意：为防万一，请将git-svn文件首先！

1. 在文本编辑器中打开git-svn脚本。我的脚本是
   < git-dir> / libexec / git-core / git-svn 。


2. 找到 is_path_ignored 子程序。


3. 在第一个<$ c之上添加一个 print $ c> return 语句，如下所示...





  sub is_path_ignored {
 my（$ self，$ path）= @_; 
 
打印STDERR$ path\\\
; //<  -  **添加此行** 
 
如果in_dot_git（$ path）返回1; 
返回1（如果已定义）（$ self-> {ignore_regex}）&& 
 $ path =〜m！$ self-> {ignore_regex} !; 
返回0，除非定义（$ _ ignore_regex）; 
返回1如果$ path =〜m！$ _ ignore_regex！o; 
返回0; 
 
 
 
 $ b现在使用 git-svn 再次使用  -  ignore-paths 开关。
 
 
 
我意识到，不是像 trunk / baz 它实际上使用 bar / trunk / baz  
 
 
 
因此，而不是 
 
 
   -  ignore-paths ='^（?:主干|分行|标记）/ baz'
  
我需要使用
   -  ignore-paths ='^ bar /（?: trunk | branches | tags）/ baz'
  
不要忘记从git-svn脚本中删除 print 语句。
 
I'm struggling for a number of hours now with the --ignore-paths option to git-svn, in an attempt to fetch only certain tags from a large repository.  

I want to start the fetch at dev, which looks like
> svn ls http://192.168.0.2/svn/repo/corporation/dev
branches/
tags/
trunk/
The repository directory listing for the complete set of tags looks like this:
> svn ls http://192.168.0.2/svn/repo/corporation/dev/tags
Acme-4.x/
Acme-5.0/
Acme-5.1/
Acme-5.2/
Acme-5.3/
Acme-5.4/
Acme-5.5/
Acme-5.6/
Acme-5.7/
Acme-5.8/
Acme-5.9/
I want to ignore all tags before Acme-5.5.

I attempt to initialize and fetch thusly:
> git svn init  http://192.168.0.2/svn/repo/corporation/dev
> git config svn.authorsfile ../users.txt
> git svn fetch --ignore-paths="Acme-4.x|Acme-5.0|Acme-5.1|Acme-5.2|Acme-5.3|Acme-5.4"
Unfortunately, I still see fetches occuring in the Acme-4.x tag.  The fetches are manifested on the console by telltale paths such as
A       ACME4.4/source/database/mssql/components/functions/vssver.scc
I've tried a bunch of variations on the regex, including full paths to the tags I want to ignore, which after an hour or two turned into utter regex thrashing and desperation.  I've provided the --ignore-paths option to git-svn-init, all to no avail.

Would someone be kind enough to comment on why the regex's are not suppressing fetches on the paths specified in the ignores-regex.

Thanks.
解决方案
I was having this same problem today: my regexp would just never match...
Make sure you know what the target paths actually look like. I was making an incorrect assumption about the structure of the paths that were being fed to my regexp.

To find out what the paths look like, make git-svn output each path to the console as it tests them: 

NOTE: Just in case, make a backup copy of the git-svn file first!

Open the git-svn script in a text editor. My script was 
<git-dir>/libexec/git-core/git-svn.
Locate the is_path_ignored subroutine.
Add a print statement above the first return statement, as follows...


sub is_path_ignored {
    my ($self, $path) = @_;

    print STDERR "$path\n"; //<-- **ADD THIS LINE**

    return 1 if in_dot_git($path);
    return 1 if defined($self->{ignore_regex}) &&
            $path =~ m!$self->{ignore_regex}!;
    return 0 unless defined($_ignore_regex);
    return 1 if $path =~ m!$_ignore_regex!o;
    return 0;
}
Now use git-svn again with the --ignore-paths switch.

I realised that instead of paths like trunk/baz it was actually using bar/trunk/baz

So instead of 
--ignore-paths='^(?:trunk|branches|tags)/baz' 
I needed to use 
--ignore-paths='^bar/(?:trunk|branches|tags)/baz'
Don't forget to remove the print statement from the git-svn script.
