/* Recursively search for commit candidates in (and under) LOCAL_ABSPATH using
WC_CTX and add those candidates to COMMITTABLES. If in ADDS_ONLY modes,
only new additions are recognized.
DEPTH indicates how to treat files and subdirectories of LOCAL_ABSPATH
when LOCAL_ABSPATH is itself a directory; see
svn_client__harvest_committables() for its behavior.
Lock tokens of candidates will be added to LOCK_TOKENS, if
non-NULL. JUST_LOCKED indicates whether to treat non-modified items with
lock tokens as commit candidates.
If COMMIT_RELPATH is not NULL, treat not-added nodes as if it is destined to
be added as COMMIT_RELPATH, and add 'deleted' entries to COMMITTABLES as
items to delete in the copy destination. COPY_MODE_ROOT should be set TRUE
for the first call for which COPY_MODE is TRUE, i.e. not for the
recursive calls, and FALSE otherwise.
If CHANGELISTS is non-NULL, it is a hash whose keys are const char *
changelist names used as a restrictive filter
when harvesting committables; that is, don't add a path to
COMMITTABLES unless it's a member of one of those changelists.
IS_EXPLICIT_TARGET should always be passed as TRUE, except when
harvest_committables() calls itself in recursion. This provides a way to
tell whether LOCAL_ABSPATH was an original target or whether it was reached
by recursing deeper into a dir target. (This is used to skip all file
externals that aren't explicit commit targets.)
DANGLERS is a hash table mapping const char* absolute paths of a parent
to a const char * absolute path of a child. See the comment about
danglers at the top of svn_client__harvest_committables().
If CANCEL_FUNC is non-null, call it with CANCEL_BATON to see
if the user has cancelled the operation.
Any items added to COMMITTABLES are allocated from the COMITTABLES
hash pool, not POOL. SCRATCH_POOL is used for temporary allocations. */
