- shutil.rmtree() fails if there are any read-only files (svn store)
- Fix files:// URLs
- os.spawnvp()/Popen4() do not exist under Windows, use subprocess
This method has several advantages:
- export3() does not work very well under Windows, while client.list() and
ra.get_file() do
- File modes are retrieved from get_file() for free, instead of being read from
the filesystem, which does not work under Windows, more generally the
filesystem is bypassed completely.
- It can be made much smarter by checkouting changed files only, like convert
extension does.
Existing code says swig bindings do not support StringIO objects as output for
svn.ra.get_file(). This issue was never reported in the convert extension.
Handle copies of items from revision X into revision Y where X is not the
parent of Y. This cannot happen in Mercurial because copies always happen
between parents and children. A file copy is recorded if:
1- Source and destination revs are in the same branch.
2- The file is unchanged (content, type, removal) through all revisions between
destination and source, not including source and destination.
Directory copies are registered only if the previous rules apply on all copied
items.
[1] is there because file copies across branches are meaningless in Mercurial
world. We could have tried to remap the source rev to a similar one in the
correct branch, but anyway the intent is wrong.
[2] is more questionable but I think it's better this way for we live in a
non-perfect svn world. In theory, 99% of copies out there should come from the
direct parent. But the direct parent is a fuzzy notion when you can have a
working directory composed of different directory at different revisions. So we
assume that stuff copied from past revisions exactly matching the content of
the direct parent revision is really copied from the parent revision. The
alternative would be to discard the copy, which would always happen unless
people kept updating the working directory after every commit (see
tests).
changes that fix problems when trunk is not the oldest branch. Also includes
fixes for copying from a tag that we chose not to create (eg tagging a vendor
branch) and includes tests for all of those things.
This test will fail if you are running an svnserve on localhost, but it checks and will not touch your data in that case.
Also fixed the push tests, which had been largely broken.
