…t, irmin-chunk, irmin-pack, irmin-mirage-graphql, irmin-mirage, irmin-graphql, irmin-http, irmin-git and irmin-test (2.0.0)
CHANGES:
#### Added
- **irmin-pack** (_new_):
- Created a new Irmin backend, `irmin-pack`, which uses a space-optimised
on-disk format.
- **irmin-graphql** (_new_):
- Created a new package, `irmin-graphql`, which provides a GraphQL server
implementation that can be used with both the MirageOS and Unix backends.
Additionally, a `graphql` command has been added to the command-line
interface for starting `irmin-graphql` servers. (mirage/irmin#558, @andreas, @zshipko)
- Contents can now be queried directly using `irmin-graphql` with
`Irmin_graphql.Server.Make_ext` and the `Irmin_graphql.Server.PRESENTER`
interface. (mirage/irmin#643, @andreas)
- **irmin-test** (_new_):
- Added a new package, `irmin-test`, which allows for packages to access the
Irmin test-suite. This package can now be used for new packages that
implement custom backends to test their implementations against the same
tests that the core backends are tested against. (mirage/irmin#508, @zshipko)
- **irmin-unix**:
- Add `Cli` module to expose some methods to simplify building command-line
interfaces using Irmin. (mirage/irmin#517, @zshipko)
- Add global config file `$HOME/.irmin/config.yml` which may be overridden by
either `$PWD/.irmin.yml` or by passing `--config <PATH>`. See `irmin help
irmin.yml` for details. (mirage/irmin#513, @zshipko)
- **irmin-git**:
- Allow import/export of Git repositories using Irmin slices. (mirage/irmin#561, @samoht)
- **irmin-http**:
- Expose a `/trees/merge` route for server-side merge operations. (mirage/irmin#714,
@samoht)
- **irmin**:
- Add `Json_value` and `Json` content types. (mirage/irmin#516 mirage/irmin#694, @zshipko)
- Add optional seed parameter to the `Irmin.Type` generic hash functions.
(mirage/irmin#712, @samoht)
- Add `V1` submodules in `Commit`, `Contents` and `Hash` to provide
compatibility with 1.x serialisation formats. (mirage/irmin#644 mirage/irmin#666, @samoht)
- Add `Store.last_modified` function, which provides a list of commits where
the given key was modified last. (mirage/irmin#617, @pascutto)
- Add a `Content_addressable.unsafe_add` function allowing the key of the new
value to be specified explicitly (for performance reasons). (mirage/irmin#783, @samoht)
- Add `save_contents` function for saving contents to the database. (mirage/irmin#689,
@samoht)
- Add pretty-printers for the results of Sync operations. (mirage/irmin#789, @craigfe)
- `Private.Lock` now exposes a `stats` function returning the number of held
locks. (mirage/irmin#704, @samoht)
#### Changed
- **irmin-unix**:
- Rename `irmin read` to `irmin get` and `irmin write` to `irmin set`. (mirage/irmin#501,
@zshipko)
- Switch from custom configuration format to YAML. (mirage/irmin#504, @zshipko)
- **irmin-git**:
- Require `ocaml-git >= 2.0`. (mirage/irmin#545, @samoht)
- Cleanup handling of remote stores. (mirage/irmin#552, @samoht)
- **irmin-http**:
- Rename `CLIENT` to `HTTP_CLIENT` and simplify the signatures necessary to
construct HTTP clients and servers. (mirage/irmin#701, @samoht)
- **irmin-mirage**
- Split `irmin-mirage` into `irmin-{mirage,mirage-git,mirage-graphql}` to
allow for more granular dependency selection. Any instances of
`Irmin_mirage.Git` should be replaced with `Irmin_mirage_git`. (mirage/irmin#686,
@zshipko)
- **irmin**:
- Update to use dune (mirage/irmin#534, @samoht) and opam 2.0. (mirage/irmin#583, @samoht)
- Replace `Irmin.Contents.S0` with `Irmin.Type.S`.
- Rename `Type.pre_digest` -> `Type.pre_hash` and `Type.hash` ->
`Type.short_hash`. (mirage/irmin#720, @samoht)
- Change `Irmin.Type` to use _incremental_ hash functions (functions of type
`'a -> (string -> unit) -> unit`) for performance reasons. (mirage/irmin#751, @samoht)
- Simplify the `Irmin.Type.like` constructor and add a new `Irmin.Type.map`
with the previous behaviour.
- Improvements to `Irmin.Type` combinators. (mirage/irmin#550 mirage/irmin#538 mirage/irmin#652 mirage/irmin#653 mirage/irmin#655 mirage/irmin#656
mirage/irmin#688, @samoht)
- Modify `Store.set` to return a result type and create a new `Store.set_exn`
with the previous exception-raising behaviour. (mirage/irmin#572, @samoht)
- Rename store module types to be more descriptive:
- replace `Irmin.AO` with `Irmin.CONTENT_ADDRESSABLE_STORE`;
- replace `Irmin.AO_MAKER` with `Irmin.CONTENT_ADDRESSABLE_STORE_MAKER`;
- replace `Irmin.RW` with `Irmin.ATOMIC_WRITE_STORE`;
- replace `Irmin.RW_MAKER` with `Irmin.ATOMIC_WRITE_STORE_MAKER`. (mirage/irmin#601,
@samoht)
- Rename `export_tree` to `save_tree` (mirage/irmin#689, @samoht) and add an option to
conditionally clear the tree cache (mirage/irmin#702 mirage/irmin#725, @samoht).
- Change hash function for `Irmin_{fs,mem,unix}.KV` to BLAKE2b rather than
SHA1 for security reasons. (mirage/irmin#811, @craigfe)
- Move `Irmin.remote_uri` to `Store.remote`, for stores that support remote
operations. (mirage/irmin#552, @samoht)
- Simplify the error cases of fetch/pull/push operations. (mirage/irmin#684, @zshipko)
- A `batch` function has been added to the backend definition to allow for
better control over how groups of operations are processed. (mirage/irmin#609, @samoht)
- A `close` function has been added to allow backends to close any held
resources (e.g. file descriptors for the `FS` backend). (mirage/irmin#845, @samoht)
- Simplify `Private.Node.Make` parameters to use a simpler notion of 'path' in
terms of a list of steps. (mirage/irmin#645, @samoht)
- Rename `Node.update` to `Node.add`. (mirage/irmin#713, @samoht)
#### Fixed
- **irmin-unix**:
- Fix parsing of commit hashes in `revert` command. (mirage/irmin#496, @zshipko)
- **irmin-git**:
- Fix `Node.add` to preserve sharing. (mirage/irmin#802, @samoht)
- **irmin-http**:
- Respond with a 404 if a non-existent resource is requested. (mirage/irmin#706, @samoht)
- **irmin**:
- Fix a bug whereby `S.History.is_empty` would return `true` for a store with
exactly one commit. (mirage/irmin#865, @pascutto)
#### Removed
- **irmin**:
- Remove `pp` and `of_string` functions from `Irmin.Contents.S` in favour of
`Irmin.Type.to_string` and `Irmin.Type.of_string`.
- Remove `Bytes` content type. (mirage/irmin#708, @samoht)
- Remove `Cstruct` dependency and content type. If possible, switch to
`Irmin.Contents.String` or else use `Irmin.Type.map` to wrap the Cstruct
type. (mirage/irmin#544, @samoht)
