bug: svn info [great [great [great]] grand] parent directory paths
I've had a search and I can't find an issue dealing with this. If it's
been mentioned already then I'm sorry...
svn info doesn't seem to behave properly when multiple ../ are used. It
also behaves differently on windows and unix (Solaris)
Examples follow:
I have omitted everything but the path svn info reports to save space.
If you need any more info or can't reproduce it then let me know.
Cheers,
Matt.

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.

I don't have a Windows box to test those suspicious-looking Windows
problems on. As for Unix, the problem seems to be just a very poor
(outright inaccurate) error message:
$ echo "Running experiment in:"; pwd; echo ""; \
for path in \
. \
../.. \
.. \
../../.. \
../../.. \
../../../ \
../../../../ \
../../../../../ \
../../../../../.. \
../../../../../../.. \
../../../../../../../..; \
do \
echo "Trying '${path}'"; \
svn info ${path} | grep "Path: "; \
echo ""; \
done
...gives this output:
Running experiment in:
/home/kfogel/src/subversion/subversion/bindings/swig/perl
Trying '.'
Path: .

subversion/libsvn_wc/lock.c:277: (apr_err=155022)

Trying '../../../../../..'
Path: ../../../../../..
Trying '../../../../../../..'
subversion/libsvn_wc/lock.c:277: (apr_err=155022)

Trying '../../../../../../../..'

svn: Path '../../../../../../../..' ends in '..', \
which is unsupported for this operation
Those errors are all for directories that are not under version
control, or at any rate are disjoint from the current directory.
Notice that there's an intermediate one ("../../../../../..") that
succeeds, even though the ones around it error. That's because
"/home/kfogel" is indeed under version control :-)
I'm not sure what to do about those Windows problems, except hope that
a Windows person has time/energy to debug. The Unix problems could
get filed as an error-message issue; would you like to do that? Just
point to this thread if you do.
Thanks,
