:: 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`
|
|

|
|
::
|
|
:: -- `lim` is the most recent date we're confident we have all the

|
:: information for. For local desks, this is always `now`. For foreign

|
|
:: This is the entry point to the commit flow. It deserves some
|
|
:: explaining, since it's rather long and convoluted.
|
|
::
|
|
:: In short, ++edit takes a ++nori and turns it into a ++nuri, which is the
|
|
:: same thing except that every change is a misu instead of a miso. Thus,
|
|
:: insertions are converted to the correct mark, diffs are applied, and
|
|
:: mutations (change content by replacement) are diffed. It also fills out
|
|
:: the other fields in `++dork`. We run `++apply-edit` to create the final
|
|
:: nuri and execute the changes.
|
|
::
|
|
:: 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 `++execute-changes: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
|
|
:: `++execute-changes:ze`, which applies the changes to our state, and then
|
|
:: we check out the new revision. XX reword
|
|
::
|
|
:: Anyhow, enough of high-level 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 knot 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 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:
|
|
::
|
|
:: -- `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.
