Hi!
The diff callbacks for handling text have revision arguments. The prop
callbacks don't.
I'm creating diff headers for the cases when we only have property
changes. When creating those diff headers I need revisions. Since the
prop diff callback doesn't have revision arguments I'm using the
revision fields in struct diff_cmd_baton. Here's what the doc string says
about those fields.
[[[
/* These are the numeric representations of the revisions passed to
svn_client_diff5, either may be SVN_INVALID_REVNUM. We need these
because some of the svn_wc_diff_callbacks4_t don't get revision
arguments.
### Perhaps we should change the callback signatures and eliminate
### these?
*/
svn_revnum_t revnum1;
svn_revnum_t revnum2;
]]]
But they don't match the revisions returned by the diff callbacks.
Here's the output from diff_content_changed() comparing what the baton
fields says and what the revision argument says (from diff_tests 32):
$ svn di -r 1 | grep DBG
DBG: diff.c: 692: btn->rev1 1, rev1 0, btn->revn2 -1, rev2 3
DBG: diff.c: 692: btn->rev1 1, rev1 0, btn->revn2 -1, rev2 3
I was under the impression that a revision is something fixed (after
we've done the peg revision dance). Any suggestion to why the revisions
may differ?
Sidenote: svn diff -r PREV:BASE shows 'working copy' as revision in the
diff label. I'm thinking 'working copy' must involve the working
changes.
Thanks,
Daniel
