the parser for the --chunker-params argument had a wrong parameter order.
fixed the order so it conforms to the help text and the docs.
also added some tests for it and a text for the ValueError exception.
borg list --short just spills out the list of files / dirs - better for some tests
and also useful on the commandline for interactive use.
the tests previously needed fakeroot because in the test setup it always
made calls to mknod and chown, which require (fake)root.
now, the tests adapt to whether it detects (fake)root or not - to run the
the tests completely, you still need fakeroot, but it won't fail all the archiver
tests just due to failing test setup.
also, a test not working correctly due to fakeroot was found:
it should detect whether a read-only repo is usable, but it failed to do that
because with (fake)root, there is no "read only" (at least not via taking away
the w permission bits).
environment context manager: if a env var was not present before, it should not be present afterwards
teardown: cd out of the tmpdir before deleting it
I re-wrote lrucache (and it seems like no-one had looked at it much
before :). I was told my test function would have been simpler in
native py.test, so let's have a go converting it all.
We can avoid any reference to unittest, because lrucache doesn't write
files so it doesn't need any of our custom assertion helpers.
this was left over from times when we either used mock from stdlib
or pypi mock. but as we only use pypi mock now, the indirection is
not needed any more.
it was silently failing until recently. and it can't work the way it is on RemoteRepository.
it's still active (and now even really working) for the (local) Repository tests.
- use power-of-2 sizes / n bit hash mask so one can give them more easily
- chunker api: give seed first, so we can give *chunker_params after it
- fix some tests that aren't possible with 2^N
- make sparse file extraction zero detection flexible for variable chunk max size
