Hello!
After some investigation I realized that PATH passed by repos
layer to AUTHZ_FUNC is not guaranted to be canonical. In fact, when
path is under copied directory (as in #4760) it does not contain
leading slash. This causes ary_prefix_match() function to ignore
those paths, since it requires canonical path.
I've attached patch with fix.
Log message:
[[[
Follow-up to r1811992: Canonicalize PATH before passing it to the FILTER_FUNC.
In some cases (e.g. for nodes under copied directories) PATH passed by
repos layer to AUTHZ_FUNC may be non-canonical (missing leading '/'). This
causes FILTER_FUNC implemented in svnadmin to wrongly report PATH as "not
included".
This fixes #4760.
* subversion/libsvn_repos/dump.c
(dump_filter_authz_func): Canonicalize PATH before passing it
to the FILTER_FUNC. Add comment.
* subversion/tests/cmdline/svnadmin_tests.py
(dump_include_copied_directory): New.
(test_list): Add new test to table.
