Sorry, yes - the different behavior seems to be that on Unix the error
message is wrong (see short example below) but that on Windows the behavior
seems to be incorrect - the parent directory paths seem to operate where if
it's an even number of ../ then it evaluates to ../.. and if it's an odd
number then it evaluates to .. (see example 2 below)

The two examples here show the effects better than my last examples.

Where would I do that? I would like to do it myself because I'd like to
become more involved in Subversion as I think it's an excellent program (I
had to evaluate it for work and after a few hours playing went home and
replaced my CVS installation with it for my own projects). I'm a
c/c++/java/php programmer.

Hopefully the windows people will indicate whether they have seen this
behavior before

Cheers,

Matt.

------------------------------
Solaris 2.6 svn, version 1.2.0 (r14790) built from 1.2.0 tarball
------------------------------

Example of:
svn info ../../../../.. gives an cryptic message, but cd to that dir and do
svninfo . and you get a sensible message.

------

itrsultra10% pwd
/export/share/mbaker/geneos/EMF2/webslinger/build/solaris
itrsultra10% svn info ../../../../..
svn: Path '../../../../..' ends in '..', which is unsupported for this
operation
itrsultra10% cd ../../../../..
itrsultra10% svn info .
svn: '.' is not a working copy

------------------------------
Windows 2000 svn, version 1.2.0 (r14790) using installer
------------------------------

Example of:
svn info ../(repeated an even number evaluating to ../..
svn info ../(repeated an odd number evaluating to ..
All dirs involved are under source control and the same branch.

------

Proving dirs are working copies:

C:\Geneos\Development\Source\EMF2\netprobe>svn info .
Path: .
URL: svn://repos/Geneos/Dev/version/Development/Source/EMF2/netprobe

C:\Geneos\Development\Source\EMF2\netprobe>cd ..

C:\Geneos\Development\Source\EMF2>svn info .
Path: .
URL: svn://repos/Geneos/Dev/version/Development/Source/EMF2

C:\Geneos\Development\Source\EMF2>cd ..

C:\Geneos\Development\Source>svn info .
Path: .
URL: svn://repos/Geneos/Dev/version/Development/Source

C:\Geneos\Development\Source>cd ..

C:\Geneos\Development>svn info .
Path: .
URL: svn://repos/Geneos/Dev/version/Development

C:\Geneos\Development>cd ..

C:\Geneos>svn info .
Path: .
URL: svn://repos/Geneos/Dev/version

------

Seeing the behavior:

C:\Geneos\Development\Source\EMF2\netprobe>svn info ..
Path: ..
URL: svn://repos/Geneos/Dev/version/Development/Source/EMF2

C:\Geneos\Development\Source\EMF2\netprobe>svn info ../..
Path: ..\..
URL: svn://repos/Geneos/Dev/version/Development/Source

C:\Geneos\Development\Source\EMF2\netprobe>svn info ../../..
Path: ..
URL: svn://repos/Geneos/Dev/version/Development/Source/EMF2

C:\Geneos\Development\Source\EMF2\netprobe>svn info ../../../..
Path: ..\..
URL: svn://repos/Geneos/Dev/version/Development/Source
