Philip, I think the follow patch addresses your concern and is also a
lot simpler than the "keep a boolean" approach I'd suggested before.
What do you think?
Fix wc corruption caused by flushing potentially-incomplete logs
during baton cleanup on error, by only appending logs to the directory
baton when they represent a complete file-level operation. Makes the
new update test #42 pass.
(dir_baton): Explicitly document that the log_accum field must
always be flushable.
(close_directory, merge_file): Instead of writing directly to
db->log_accum, make a temporary svn_stringbuf_t, write to it, and
append it to db->log_accum in one operation at the end.
(test_list): eof_in_interactive_conflict_resolver now passes.
