Hi, Obliterate fans.
As of r893267, if you compile with "-DSVN_WITH_EXPERIMENTAL_OBLITERATE",
you get an "svn obliterate" subcommand which is capable of obliterating
the latest revision of a file. In my tests so far, it seems to work in
very limited circumstances.
You can run the "obliterate_tests.py" which creates a test repository
and then tries to do five obliterates. The first obliterate on a node
path "f-mod/F" works, and then it fails on the next one "f-add/F". If
you go to the working copy and try examining the history, can you find
any errors?
May not work:
? Node is a directory
- I think I implemented it, but not yet tested so probably not yet
working.
Does not work:
x Node was added in that revision
- A bug which I have not traced yet: "No record in 'node-origins'
table for node id 'a'".
x Node has any successors (incl. copies) in a later revision
- This includes any obliteration in a non-head revision.
- Their reps and even node-revs will still refer to the obliterated
one so the repository will definitely be messed up.
- This is one of the next steps to implement.
x FSFS
- I'm implementing only in BDB at the moment.
x Remote RA methods
- I'm implementing only for RA-local at the moment.
There is also a bug in conjunction with trying to update the test's WC
from r10 (in which the test obliteration occurred) back to r9: it raises
a tree conflict but does not change the base rev to 9, and I can find no
way from the command line to resolve the conflict and update to r9 or
update to the new (obliterated) version of r10. I wonder if (for testing
purposes) we can avoid this bug by updating the WC to r9 before
performing the obliterate.
Testing and other feedback greatly welcomed. Does it work for a
directory?
