sys/conf/newvers.sh vs. subversion-1.7

[Craig Rodrigues]

Hi,

I tried following:

(1)   Run svnversion in non-svn directory:

   return status == 0
   prints out "exported"

time:
real    0m0.043s
user    0m0.000s
sys     0m0.045s

(2)  Run svnversion in svn directory:

   return status == 0
   prints out "223847M"

time:
real    0m2.563s
user    0m0.980s
sys     0m1.187s


(3)  Run "svn info --non-interactive  ." in non-svn directory:

   return status == 1
   prints out "svn: '.' is not a working copy"

time:

real    0m0.056s
user    0m0.007s
sys     0m0.046s


(4)   Run "svn info --non-interactive ." in svn directory:

    return status == 0
    prints out "a bunch of info about from svn"

time:

real    0m0.023s
user    0m0.000s
sys     0m0.024s



I thought that since svnversion seems to always have a return status of 0, and
is almost 2 seconds slower than "svn info" when run inside a svn directory,
that using "svn info" is a preferable way inside a script of determining
if a directory is part of a svn repo or not.
