Joey Hess 10b5f79e2d fix empty tree import when directory does not exist ... Fix behavior when importing a tree from a directory remote when the directory does not exist. An empty tree was imported, rather than the import failing. Merging that tree would delete every file in the branch, if those files had been exported to the directory before. The problem was that dirContentsRecursive returned [] when the directory did not exist. Better for it to throw an exception. But in commit 74f0d67aa3 back in 2012, I made it never theow exceptions, because exceptions throw inside unsafeInterleaveIO become untrappable when the list is being traversed. So, changed it to list the contents of the directory before entering unsafeInterleaveIO. So exceptions are thrown for the directory. But still not if it's unable to list the contents of a subdirectory. That's less of a problem, because the subdirectory does exist (or if not, it got removed after being listed, and it's ok to not include it in the list). A subdirectory that has permissions that don't allow listing it will have its contents omitted from the list still. (Might be better to have it return a type that includes indications of errors listing contents of subdirectories?) The rest of the changes are making callers of dirContentsRecursive use emptyWhenDoesNotExist when they relied on the behavior of it not throwing an exception when the directory does not exist. Note that it's possible some callers of dirContentsRecursive that used to ignore permissions problems listing a directory will now start throwing exceptions on them. The fix to the directory special remote consisted of not making its call in listImportableContentsM use emptyWhenDoesNotExist. So it will throw an exception as desired.
