hot-backup.py fails
Hello,
As I know nothing of Python at all, I come to you with a question.
Hopefully somebody will be kind enough to help me.
The hot-backup.py script fails. This is what it says:
Beginning hot backup of '/home/switch/svn/currentdb/MAL2/'.
Traceback (innermost last):
File
"/home/switch/svn/current/usr/lib/subversion/tools/backup/hot-backup.py",
line 94, in ?
infile, outfile, errfile = os.popen3(svnlook + " youngest " + repo_dir)
AttributeError: popen3
-------- end of output -----------
What does this mean?
What's going wrong here?
RPM claims that this is installed: python-1.5.2-38. I'm trying this on
RH advanced server, which is very much comparable to RH 7.3.
Thanks for any help you could provide.
Jan Evert

Which line fails? Can you post the traceback?

Anthony,
thanks for this suggestion, it makes this line work.
But now the next line then fails.
I guess the better option is to install a newer python.
Thanks,
Jan Evert

Alternately, replace the code with
import popen2
popen2.popen3(...)
This should work on older versions of Python as well as newer versions.

This is no longer the case. Certainly, on this RH9 system, python is
python2.2.2. I think that RH8 and later ships with python2.2.

If it's just popen3 that's needed, the above fix is better. If there's
other reasons for Python2, then you'll need something like the above.
Note, though, that sys.version_info wasn't in Python 1.5.2. You instead
want something like
version = string.split(sys.version)[0]
if version < '2':
raise UpgradePythonPlease

In other words, install a more recent version of Python and the script
should work.
This should probably be noted somewhere because RedHat continues to ship
(AFAIK) with an _old_ version of Python (1.5.x). Perhaps something like
the following could be added to hot-backup.py:
major = sys.version_info[0]
if major < 2: # tell user to upgrade Python and exit gracefully

I believe that popen3 is new to Python 2.x.
