Problems with actual cygwin subversion

[Carsten Schlote <ca...@gmx.net>]

Hi,

I started working with subversion some time ago. I installed the native
win32 subversion and explorer shell extention.

Additionally I installed the subversion cgywin package, because I use cygwin
as my primary shell on windows. I also use GNU make and other tools. 

I encountered some problems, if you configure cygwin to automatically use
CRLF expansion (DOS mode). It seems to corrupt files in .svn and probaly
files marked as binary (Base checksum mismatch on... problem). 

I changed the cygwin setup to use UNIX mode for cygwin. I'm not completely
through with my tests, but this might fix some of the problems.

I'm really interested to use subversion within the cygwin environment, I'd
like to know who is the current cygwin package maintainer. So I might help
with adapting subversion to work in bothe mode, DOS and UNIX.

I really want to avoid the windows path conversion games within my make
scripts.

Which package? There is no official Cygwin package yet.

Should do, I've been using built-from-source subversion on Cygwin for a
while. Binary/UNIX mode and no problems.

There is no current cygwin package maintainer, because there is no current
Cygwin package. In any case, Cygwin policy is that packaging problems should
be addressed on the cygwin-apps mailing list, *not* direct to the individual
package maintainer.

That's correct.  As far as Subversion is concerned, Cygwin == Unix, so 
Subversion does no EOL translation when checking out the files from the 
repository.  The DOS mode hack changes the file's contents behind the scenes, so 
this messes up the checksums as you've found.  As long as you use binmode mounts 
and not textmode, you are fine.
