Public bug reported:
Binary package hint: mercurial
Using "hg convert" to convert a Subversion repository to Mercurial
requires python-subversion, but this requirement is not documented.
Example:
"""
$ sudo apt-get remove python-subversion
[...]
$ svnadmin create /tmp/repo1
$ hg convert /tmp/repo1
assuming destination repo1-hg
initializing destination repo1-hg repository
abort: /tmp/repo1: unknown repository type
"""
You have to guess that adding --debug to the hg command line might help:
"""
$ hg --debug convert -s svn /tmp/repo1
assuming destination repo1-hg
initializing destination repo1-hg repository
convert: subversion python bindings could not be loaded
abort: /tmp/repo1: unknown repository type
"""
After this, I was able to figure out that "apt-get install python-
subversion" might help, and indeed it did. However, the Ubuntu package
of mercurial neither "Suggests" nor "Recommends" python-subversion. If
I understand correctly, this should be a "Suggests" dependency: it's not
core functionality, but it is a feature of mercurial that does not work
without python-subversion.
Source package: mercurial
Version: 0.9.5-3
Ubuntu release: 8.04 "hardy"
Oh yeah: what I *expected* to happen, of course, was a flawless
conversion of my Subversion repository to Mercurial without any
additional work on my part. I would be happy, though, if
hg convert /tmp/repo1
failed with a clear error message like
cannot convert Subversion repository /tmp/repo1: subversion python
bindings could not be loaded
...i.e. I should not have had to use "--debug" to find out the problem.
For bonus points, it would be nice to have a Debian/Ubuntu patch that
enhanced the error message to
cannot convert Subversion repository /tmp/repo1: subversion python
bindings could not be loaded (did you install python-subversion?)
or something similar.
