If I try to call client.info2(foo) on a path 'foo' that is
missing a
subversion controlled subdirectory 'bar' (or the bar/.svn
dir within it) I get a
seg fault.
client.status(foo) and client.info(foo) work fine and if I
restore the
subdirectory bar or non-recursively update the parent
directory foo to a
revision before bar existed then info2(foo) works fine.
Missing files don't
pose a problem. client.status(foo) just reports bar as
missing as it should.
Details follow
python 2.5.1 (also tested 2.4.3, 2.4.4)
pysvn 1.5.3 (also tested 1.5.2)
subversion 1.4.4
Ubuntu 6.06 kernel 2.6.18.8
> mkdir /trunk/foo/bar
> svn add /trunk/foo/bar
> svn commit /trunk/foo/bar -m "new bar
directory"
> rm -rf /trunk/foo/bar/.svn
# (same results if I remove bar entirely)
> python
>>> import pysvn
>>> client = pysvn.Client()
>>> client.info2("/trunk/foo")
Segmentation fault
I wrote a small test script pysvnTestBroken and ran it
through gdb and it
looks like the problem manifests itself in the
InfoReceiveBaton destructor.
In this case the checked out path 'foo' was missing a
subdirectory 'bar' that
had been committed to svn as in the example above.
