Hi All,
I just ran into an issue with the rstrip method when using it on path
strings.
When executing a function I have a need to strip off a portion of the
current working directory and add on a path to a log file. Initially
this worked great but then I added a branch in SVN which caused the path
to contain 'LNCCWorkshop'. The rstrip() then began removing the
characters 'shop' leaving an incorrect path to the log file. When I
hard coded this path it worked okay but then did the same thing later in
the file when I needed to point to a database. The code worked fine with
a different path. Here are some code fragments.
logfile=os.getcwd().rstrip('src/oship/atbldr')+'/oship/log/at_build_errors.log'
this worked when the path was:
/home/tim/ref_impl_python/TRUNK/oship/src/oship/atbldr
the code above returns:
/home/tim/ref_impl_python/TRUNK/oship/log/at_build_errors.log
but when I tried a branches version that has the path:
/home/tim/ref_impl_python/BRANCHES/LNCCWorkshop/oship/src/oship/atbldr
it SHOULD return:
/home/tim/ref_impl_python/BRANCHES/LNCCWorkshop/oship/log/at_build_errors.log
but I get:
/home/tim/ref_impl_python/BRANCHES/LNCCWork/oship/log/at_build_errors.log
logfile=os.getcwd()
print logfile is correct; but when I add the .rstrip('src/oship/atbldr')
it also strips the 'shop' off of LNCCWorkshop and returns
/home/tim/ref_impl_python/BRANCHES/LNCCWork/oship/log/at_build_errors.log
I had two other people looking at this as we did troubleshooting and we
could not determine the cause. It is repeatable with this path name.
In resolution I renamed the branch to just LNCC and it works fine.
Thoughts?

Always helps to consult documentation when things don't work.
Help on built-in function rstrip:
rstrip(...)
S.rstrip([chars]) -> string or unicode
Return a copy of the string S with trailing whitespace removed.
If chars is given and not None, remove characters in chars instead.
If chars is unicode, S will be converted to unicode before stripping
If you give chars to rstrip() it removes all those characters from the string
not that substring.
