svndumpfilter on Win32

[anonymous anonymous <fl...@yahoo.com>]

I am trying to use svndumpfilter on a Windows platform to create a new 
repository for each project in one old repository.  I have followed 
the documentation in order to do this by first dumping the old 
repository into a dumpfile like this:
 
svnadmin dump repos > repos-dumpfile
 
Next, the documentation says to pipe the linux cat command through the 
svndumpfilter program like this:
 
cat repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
 
I have tried this with the following methods, since DOS does not 
include cat:
 
type repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
more repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
print /D:CON repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
 
Also, I downloaded the cat program for DOS from 
unxutils.sourceforge.net and tried these methods:
 
cat repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
cat �A repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
cat �B repos-dumpfile | svndumpfilter include project1 > project1-dumpfile
 
where �A means all of the file and �B means to treat the file as a 
binary file.
 
In each case (that produced anything) the generated filtered dumpfile 
was very small.  When I tried to load the filtered dumpfile into a 
newly created repository, it created all the revision numbers, but the 
repository remained empty (no data).
 
Has anyone been successful using the svndumpfilter program on a 
Windows platform?  If so, how!?  Also, is this a functionality that 
the Subversion software should be able to accomplish without relying 
on an external program, i.e. cat?
 
Thanks in advance,
 
Floor

<rant> Argh! 'cat' is a program, not a 'linux command' - whatever that should 
be. It's existed for much longer than aforementioned OS kernel, which btw is 
written with a capital L. </rant>

'type' itself says it is for textfiles, but a dumpfile isn't a textfile, so 
that is possibly not a suitable tool.

Have you tried using both?

Using Cygwin, yes. ;)

You can, you just have to redirect input and output of dumpfilter:
  svndumpfilter ... < inputfile > outputfile
assuming your shell supports it, which might be the problem with the native 
shell under MS Windows (possibly depending on the version thereof). I tried 
under the shell of MS Windows 2000 and using that syntax for a textfile 
works.
