Summary: The FakeTreeBuilder class in D4609587 provides a lot of the same functionality as the TestMountBuilder class, but is not restricted to being used only at mount initialization time. (It also provides more powerful functionality for controlling the ordering of events when loading data from the ObjectStore.) This switches all of the existing tests to use FakeTreeBuilder rather than TestMountBuilder, and removes the TestMountBuilder class. One difference is that FakeTreeBuilder adds data to the FakeBackingStore, while TestMountBuilder previously put data directly into the LocalStore. This shouldn't really make much difference for the behavior of the code. Putting data in the FakeBackingStore gives us more control over when data is available during load operations, and exercises slightly more of the normal ObjectStore code path.

// Currently calling TreeInode::unlink() and TreeInode::rename() here does
|
|
// not work. (TreeInode::getChildByName() does not correctly register new
|
|
// inodes it creates in the EdenDispatcher's inode map. The unlink() and
|
|
// rename() operations require that the inode exist in the dispatcher map.)
|

//
|
|
// I am currently working on refactoring the inode map in a subsequent diff.
|
|
// My refactoring ensures that inodes always get registered correctly,
|
|
// regardless of how they are created. I'll come back and work on test cases
|
|
// here once my refactored InodeMap code lands.
