The initial patch is below. It's a quick mock-up, but it removes the
need for a public symbol for the adm dir name -- except for one place in
libsvn_subr, where I've left the current code in because we'd get a
circular dependency between libsvn_wc and libsvn_subr, which I don't
quite know how to handle yet.
The point is that if/when this is in, we can keep the knowledge about
the actual admin directory name inside libsvn_wc/adm_files.c. If we
decide that getenv is appropriate for 1.x, we can still cache the result
in the local variable (using apr_atomc_casptr to change the value; we
seem to have forgotten that APR has had atomics since at least 0.9.5, if
not earlier, so this kind of local caching can be entirely safe).
Tests pass on Windows with this patch.
[[[
Remove knowledge about the admin directory name from the public
API, preparing the way for run-time parameterisation.
* subversion/include/svn_wc.h (svn_wc_is_adm_dir): New prototype.
(SVN_WC_ADM_DIR_NAME): Deprecate.
* subversion/libsvn_wc/adm_files.c (DEFAULT_ADM_DIR_NAME): New constant.
(adm_dir_name) New file-scope variable.
(svn_wc_is_adm_dir): Implement.
(v_extend_with_adm_name): Use adm_dir_name instead of SVN_WC_ADM_DIR_NAME.
* subversion/libsvn_wc/copy.c (post_copy_cleanup): Call svn_wc__adm_path
to construct the path to the admin directory.
* subversion/libsvn_wc/adm_ops.c (erase_from_wc),
subversion/libsvn_wc/status.c (get_dir_status),
subversion/libsvn_wc/update_editor.c (add_directory),
subversion/libsvn_client/add.c (add_dir_recursive),
subversion/libsvn_client/commit.c (import_dir, svn_client_import2):
Call svn_wc_is_adm_dir instead of strcmp'ing with SVN_WC_ADM_DIR_NAME.
* subversion/libsvn_subr/opt.c (svn_opt_args_to_target_array2):
Mark the place where a similar change should be made.
