/*
* This code handles "checkout" and "update" and "switch".
* A checkout is similar to an update that is only adding new items.
*
* The intended behaviour of "update" and "switch", focusing on the checks
* to be made before applying a change, is:
*
* For each incoming change:
* if target is already in conflict or obstructed:
* skip this change
* else
* if this action will cause a tree conflict:
* record the tree conflict
* skip this change
* else:
* make this change
*
* In more detail:
*
* For each incoming change:
*
* 1. if # Incoming change is inside an item already in conflict:
* a. tree/text/prop change to node beneath tree-conflicted dir
* then # Skip all changes in this conflicted subtree [*1]:
* do not update the Base nor the Working
* notify "skipped because already in conflict" just once
* for the whole conflicted subtree
*
* if # Incoming change affects an item already in conflict:
* b. tree/text/prop change to tree-conflicted dir/file, or
* c. tree change to a text/prop-conflicted file/dir, or
* d. text/prop change to a text/prop-conflicted file/dir [*2], or
* e. tree change to a dir tree containing any conflicts,
* then # Skip this change [*1]:
* do not update the Base nor the Working
* notify "skipped because already in conflict"
*
* 2. if # Incoming change affects an item that's "obstructed":
* a. on-disk node kind doesn't match recorded Working node kind
* (including an absence/presence mis-match),
* then # Skip this change [*1]:
* do not update the Base nor the Working
* notify "skipped because obstructed"
*
* 3. if # Incoming change raises a tree conflict:
* a. tree/text/prop change to node beneath sched-delete dir, or
* b. tree/text/prop change to sched-delete dir/file, or
* c. text/prop change to tree-scheduled dir/file,
* then # Skip this change:
* do not update the Base nor the Working [*3]
* notify "tree conflict"
*
* 4. Apply the change:
* update the Base
* update the Working, possibly raising text/prop conflicts
* notify
*
* Notes:
*
* "Tree change" here refers to an add or delete of the target node,
* including the add or delete part of a copy or move or rename.
*
* [*1] We should skip changes to an entire node, as the base revision number
* applies to the entire node. Not sure how this affects attempts to
* handle text and prop changes separately.
*
* [*2] Details of which combinations of property and text changes conflict
* are not specified here.
*
* [*3] For now, we skip the update, and require the user to:
* - Modify the WC to be compatible with the incoming change;
* - Mark the conflict as resolved;
* - Repeat the update.
* Ideally, it would be possible to resolve any conflict without
* repeating the update. To achieve this, we would have to store the
* necessary data at conflict detection time, and delay the update of
* the Base until the time of resolving.
