Raw Blame History

:: clay (4c), revision control
::
:: The way to understand Clay is to take it section-by-section:
::
:: - Data structures. You *must* start here; make sure you understand
:: the entire contents of +raft.
::
:: - Individual reads. +aver is the entry point, follow it through
:: +read-at-tako to understand each kind of read.
::
:: - Subscriptions. +wake is the center of this mechanism; nothing
:: else responds to subscriptions. +wake has no arguments, which means
:: every subscription response happens when something in Clay's *state*
:: has changed. No edge-triggered responses.
::
:: - Receiving foreign data. For individual requests, this is
:: +take-foreign-answer. For sync requests (%many, which is %sing %v
:: for a foreign desk), this is +foreign-update.
::
:: - Ford. +ford builds hoon files and gives files their types.
:: Read +build-file for the first, and +read-file is the second.
::
:: - Writing to a desk. Every write to a desk goes through +park, read
:: it thoroughly.
::
:: - Merges. Control flow starts at +start-merge, then +merge, but
:: everything is scaffolding for +merge-by-germ, which is the ideal of
:: a merge function: it takes two commits and a merge strategy and
:: produces a new commit.
::
:: - Tombstoning. This is in +tomb.
::
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::
:: We use a system of "invariant footnotes", where nonlocal invariants
:: are tagged with notes to construct a distributed argument that the
:: invariant is maintained. For example, see [wake].
::
:: Each one should be described somewhere, and then it should be
:: referenced any time it's touched. For example, any code which might
:: fill a subscription should be tagged with [wake], and if +wake is
:: not called by the end of that function, the function itself should
:: be tagged with [wake].
::
:: The tagged code should constitute an argument that the invariant is
:: maintained everywhere. While this is vulnerable to omission ("I
:: forgot that X could fill a subscription", it provides a good minimum
:: bar.
::
:: Tag the specific line of code which affects the invariant. You do
:: not need to tag every function in a call stack if the invariant is
:: guaranteed to be maintained by the time the function returns.
::
:: Some invariant references get tagged with whether they "open" or
:: "close" the invariant. For example, adding a commit to the dome
:: "opens" the [wake] invariant, while calling +wake closes it. When
:: an invariant opens, you should be able to scan down and find why it
:: closes in each possible flow of control. For wake, these are
:: labeled like this:
::
:: open: [wake] <
:: close: [wake] >
:: open and almost immediately close: [wake] <>
::
:: This system is best used for nonlocal invariants and is not
:: necessary when a function can guarantee its own invariants. For
:: example, consider a set alongside a @ud representing its size.
:: There is an invariant that any time you add or remove an item from
:: the set you must update its size. If you're operating on these
:: directly, it could be beneficial to tag each line of code which
:: might modify the set and make it clear where the size is modified.
::
:: Sometimes code can be restructured so that many fewer tags are
:: needed. In the above example, if the set is modified in many
:: places, it may be worth factoring out set+size into a data structure
:: with its own arms for put, del, uni, int, etc. Then the invariant
:: only needs to be maintained within that data structure, and call
:: sites do not need to be tagged.
::
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::
:: Here are the structures. `++raft` is the formal arvo state. It's
:: also worth noting that many of the clay-related structures are
:: defined in lull.

:: 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:
::
:: -- local urbit `our`
:: -- current time `now`
:: -- current duct `hen`
:: -- scry handler `ski`
:: -- all vane state `++raft` (rarely used, except for the object store)
:: -- 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.
::
:: 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:
::
:: -- `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.

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::
:: 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 content
:: -- 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:
::
:: -- `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.
::
