:: section 4cA, filesystem logic
::
:: This core contains the main logic of clay. Besides `++ze`, this directly
:: contains the logic for commiting new revisions (local urbits), managing
:: and notifying subscribers (reactivity), and pulling and validating content
:: (remote urbits).
::
:: The state includes:
::
:: -- current time `now`
:: -- current duct `hen`
:: -- local urbit `our`
:: -- target urbit `her`
:: -- target desk `syd`
:: -- all vane state `++raft` (rarely used, except for the object store)
::
:: For local desks, `our` == `her` is one of the urbits on our pier. For
:: foreign desks, `her` is the urbit the desk is on and `our` is the local
:: urbit that's managing the relationship with the foreign urbit. Don't mix
:: up those two, or there will be wailing and gnashing of teeth.
::
:: While setting up `++de`, we check if the given `her` is a local urbit. If
:: so, we pull the room from `fat` in the raft and get the desk information
:: from `dos` in there. Otherwise, we get the rung from `hoy` and get the
:: desk information from `rus` in there. In either case, we normalize the
:: desk information to a `++rede`, which is all the desk-specific data that
:: we utilize in `++de`. Because it's effectively a part of the `++de`
:: state, let's look at what we've got:
::
:: -- `lim` is the most recent date we're confident we have all the
:: information for. For local desks, this is always `now`. For foreign
:: desks, this is the last time we got a full update from the foreign
:: urbit.
:: -- `ref` is a possible request manager. For local desks, this is null.
:: For foreign desks, this keeps track of all pending foreign requests
:: plus a cache of the responses to previous requests.
:: -- `qyx` is the set of subscriptions, keyed by duct. These subscriptions
:: exist only until they've been filled.
:: -- `dom` is the actual state of the filetree. Since this is used almost
:: exclusively in `++ze`, we describe it there.
:: -- `dok` is a possible set of outstanding requests to ford to perform
:: various tasks on commit. This is null iff we're not in the middle of
:: a commit.
:: -- `mer` is the state of a possible pending merge. This is null iff
:: we're not in the middle of a merge. Since this is used almost
:: exclusively in `++me`, we describe it there.

::
:: This is the entry point to the commit flow. It deserves some
:: explaining, since it's rather long and convoluted.
::
:: We take a `++nori`, which is either a label-add request or a `++soba`,
:: which is a list of changes. If it's a label, it's easy and we just pass
:: it to `++edit:ze`.
::
:: If the given `++nori` is a list of file changes, then we our goal is to
:: convert the list of `++miso` changes to `++misu` changes. In other
:: words, turn the `++nori` into a `++nuri`. Then, we pass it to
:: `++edit:ze`, which applies the changes to our state, and then we
:: check out the new revision. XX reword
::
:: Anyhow, enough of high-level wishy-washy talk. It's time to get down to
:: the nitty-gritty.
::
:: When we get a list of `++miso` changes, we split them into four types:
:: deletions, insertions, diffs (i.e. change from diff), and mutations
:: (i.e. change from new data). We do four different things with them.
::
:: For deletions, we just fill in `del` in `++dork` with a list of the
:: deleted files.
::
:: For insertions, we distinguish bewtween `%hoon` files and all other
:: files. For `%hoon` files, we just store them to `ink` in `++dork` so
:: that we add diff them directly. `%hoon` files have to be treated
:: specially to make the bootstrapping sequence work, since the mark
:: definitions are themselves `%hoon` files.
::
:: For the other files, we make a `%tabl` compound ford request to convert
:: the data for the new file to the the mark indicated by the last span in
:: the path.
::
:: For diffs, we make a `%tabl` compound ford request to apply the diff to
:: the existing content. We also store the diffs in `dig` in `++dork`.
::
:: For mutations, we make a `%tabl` compound ford request to convert the
:: given new data to the mark of the already-existing file. Later on in
:: `++take-castify` we'll create the ford request to actually perform the
:: diff. We also store the mutations in `muc` in `++dork`. I'm pretty
:: sure that's useless because who cares about the original data.
:: XX delete `muc`.
::
:: Finally, for performance reasons we cache any of the data that came in
:: as a `%mime` cage. We do this because many commits come from unix,
:: where they're passed in as `%mime` and need to be turned back into it
:: for the ergo. We cache both `%hoon` and non-`%hoon` inserts and
:: mutations.
::
:: At this point, the flow of control goes through the three ford requests
:: back to `++take-inserting`, `++take-diffing`, and `++take-castifying`,
:: which itself leads to `++take-mutating`. Once each of those has
:: completed, we end up at `++apply-edit`, where our unified story picks up
:: again.

:: This core has no additional state, and the distinction exists purely for
:: documentation. The overarching theme is that `++de` directly contains
:: logic for metadata about the desk, while `++ze` is composed primarily
:: of helper functions for manipulating the desk state (`++dome`) itself.
:: Functions include:
::
:: -- converting between cases, commit hashes, commits, content hashes,
:: and conent
:: -- creating commits and content and adding them to the tree
:: -- finding which data needs to be sent over the network to keep the
:: -- other urbit up-to-date
:: -- reading from the file tree through different `++care` options
:: -- the `++me` core for merging.
::
:: The dome is composed of the following:
::
:: -- `ank` is the ankh, which is the file data itself. An ankh is both
:: a possible file and a possible directory. An ankh has both:
:: -- `fil`, a possible file, stored as both a cage and its hash
:: -- `dir`, a map of @ta to more ankhs.
:: -- `let` is the number of the most recent revision.
:: -- `hit` is a map of revision numbers to commit hashes.
:: -- `lab` is a map of labels to revision numbers.

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::
:: This core is specific to any currently running merge. This is
:: basically a simple (DAG-shaped) state machine. We always say we're
:: merging from 'ali' to 'bob. The basic steps, not all of which are
:: always needed, are:
::
:: -- fetch ali's desk
:: -- diff ali's desk against the mergebase
:: -- diff bob's desk against the mergebase
:: -- merge the diffs
:: -- build the new state
:: -- "checkout" (apply to actual `++dome`) the new state
:: -- "ergo" (tell unix about) any changes
::
:: The state filled in order through each step:
::
:: -- `sor` is the urbit and desk of ali.
:: -- `hen` is the duct that instigated the merge.
:: -- `gem` is the merge strategy. These are described in
:: `++fetched-ali`.
:: -- `wat` is the current step of the merge process.
:: -- `cas` is the case in ali's desk that we're merging from.
:: -- `ali` is the commit from ali's desk.
:: -- `bob` is the commit from bob's desk.
:: -- `bas` is the commit from the mergebase.
:: -- `dal` is the set of changes from the mergebase to ali's desk.
:: -- `dob` is the set of changes from the mergebase to bob's desk.
:: These two merit slightly more explanation. There are four kinds
:: of changes:
:: -- `new` is the set of files in the new desk and not in the
:: mergebase.
:: -- `cal` is the set of changes in the new desk from the mergebase
:: except for any that are also in the other new desk.
:: -- `can` is the set of changes in the new desk from the mergebase
:: and that are also in the other new desk (potential conflicts).
:: -- `old` is the set of files in the mergebase and not in the new
:: desk.
:: -- `bof` is the set of changes to the same files in ali and bob.
:: Null for a file means a conflict while a cage means the diffs
:: have been merged.
:: -- `bop` is the result of patching the original files with the above
:: merged diffs.
:: -- `new` is the newly-created commit.
:: -- `ank` is the ankh for the new state.
:: -- `erg` is the sets of files that should be told to unix. True
:: means to write the file while false means to delete the file.
:: -- `gon` is the return value of the merge. On success we produce a
:: set of the paths that had conflicting changes. On failure we
:: produce an error code and message.
