:: 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:
::
2018-12-13 10:42:15 +03:00
:: -- local urbit `our`
2016-11-24 07:25:07 +03:00
:: -- current time `now`
:: -- current duct `hen`
2019-02-02 00:46:09 +03:00
:: -- scry handler `ski`
2018-12-13 10:42:15 +03:00
:: -- all vane state `++raft` (rarely used, except for the object store)
2016-11-24 07:25:07 +03:00
:: -- target urbit `her`
:: -- target desk `syd`
::
:: 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.
::
2018-12-13 10:42:15 +03:00
:: While setting up `++de`, we check if `our` == `her`. If so, we get
:: the desk information from `dos.rom`. 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:
2016-11-24 07:25:07 +03:00
::
:: -- `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, with listening ducts. 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.

:: of helper functions for manipulating the desk state (`++dome`) itself.
:: Functions include:
::
:: -- converting between cases, commit hashes, commits, content hashes,

:: -- creating commits and content and adding them to the tree
:: -- finding which data needs to be sent over the network to keep the

:: -- 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.
