Subject RE: Bug patching Unicode files
Date Fri, 25 Nov 2016 12:38:02 GMT
Apart from that, I tried to fix the diff file myself, just to check if the
error was only during the generation of the diff file or also to apply an
Unicode diff file. I edited the “changes.diff” file using Notepad++ and
removed the “\0” codes, so I had an ANSI diff file called
“changes_fixed.diff” that also fails in the same way to apply the patch. I
also converted the ANSI diff file into an Unicode UCS2-LittleEndian file
with Notepad++, and now Subversion cannot apply the patch…  So, it seems
there could be three bugs there: one in the creation of diff files, another
one applying ANSI diff files to Unicode files, and another just working with
Unicode diff files. I attach all the examples again, with the manually fixed
diff files. Best regards,


Hugo González

Asunto: Bug patching Unicode files


Hello, and congratulations for your great job at the Subversion project. I
think it is an amazing tool.

I have found a bug when trying to apply a patch over a Unicode file. The
steps to reproduce this bug are:


1.       Create and version a Unicode file in your repository, for example:

2.       Modify that Unicode file.

3.       Create a patch with your modifications (svn diff > changes.diff)

4.       Revert the modifications of the file.

5.       Apply the patch to modify the file again (svn patch changes.diff)

6.       You get a corrupted file and the modifications are lost.


It seems the diff file is malformed, resulting in a corrupted patched file.
I attach the documents of my example.

I hope you can fix this, because I work with a lot of Unicode files, but I
understand this could be difficult because of command line limitations…

Any feedback or advice will be welcome. Thank you very much in advance,


Hugo González
