I'm not sure it's the right solution -- it might just be working round
a bug.
The problem only occurs when the deleted file is a direct child of a
copied directory, if it's in a subdirectory then there is no problem.
The difference is this bit of code near the start of
entries.c:write_entry:
switch (entry->schedule)
{
[...]
case svn_wc_schedule_delete:
working_node = MAYBE_ALLOC(working_node, scratch_pool);
/* If the entry is part of a REPLACED (not COPIED) subtree,
then it needs a BASE node. */
if (! (entry->copied
|| (this_dir->copied
&& this_dir->schedule == svn_wc_schedule_add)))
base_node = MAYBE_ALLOC(base_node, scratch_pool);
break;
When the deleted file is a direct child of the copied directory then
this_dir->schedule is svn_wc_schedule_add, but when it's in a subdir
it's svn_wc_schedule_normal. (That's the usual directory is copied
but subdirs are normal thing.) So when I do:
svn cp wc/A wc/A2
svn rm wc/A2/f wc/A2/B/f
the code above allocates a base_node for A2/B/f but not for A2/f.
Later on in the function:
if (entry->schedule == svn_wc_schedule_delete)
{
if (entry->incomplete)
{
[...]
}
else
{
/* If the entry is part of a COPIED (not REPLACED) subtree,
then the deletion is referring to the WORKING node, not
the BASE node. */
if (entry->copied
|| (this_dir->copied
&& this_dir->schedule == svn_wc_schedule_add))
working_node->presence = svn_wc__db_status_not_present;
else
working_node->presence = svn_wc__db_status_base_deleted;
}
does the same sort of thing and results in two different
working_node->presence values.
The overall result is that
svn cp wc/A wc/A2
svn rm wc/A2/B/f
gets a working node with presence base-deleted and a base node, while
svn cp wc/A wc/A2
svn rm wc/A2/f
gets a working node with presence not-present and no base node.
I don't really understand why these cases should be different, and the
comment about "REPLACED (not COPIED)" doesn't seem to apply because
neither item is replaced.
If I use the debugger to tweak this_dir->schedule to
svn_wc_schedule_normal during "svn rm wc/A2/f" then the subsequent
commit works.
