package datakit-client

0.11.0 (2017-07-07)

The main change in this release is the addition of datakit-client-git which implements the DataKit API on top of a normal Git repository. This means that the deployment of DataKit tools is now much simpler as they do not need a running DataKit server anymore. The client and server packages have been renamed to make the use of 9p more explicit. Support for more transport is planned, including gRPC and Cap-n-proto.

Go bindings

• Go: Separate user config from defaults in the database (#523, @djs55)

• Go: add List to list files in snapshots (#578, @ebriney)

datakit-server, datakit-client

• client/server: split the libraires between core API and 9p transport.

  There is now:

  • datakit-client: signature for client API + Path library

  • datakit-server: implementation of the VFS on top of Irmin

  • datakit-client-9p: implementation of the API using 9p as transport

  • datakit-server-9p: expose the Irmin VFS as the Datakit API; server-side implementation of the API using 9p as transport

  The tests are split as well, so all the client/server tests can be re-used with a different transport mechanism. (#551, @samoht)

• client: add a top-level Datakit_client module namespace: Datakit_S.CLIENT becomes Datakit_client.S and Datakit_path becomes Datakit_client.Path (#558, @samoht)

• client: remove rename API calls (#563, @samoht)

datakit-client-9p

datakit-client-9p is now the new name for the previously named datakit-client. That package contains the 9p client bindings to the DataKit API. More clients to come.

• 9p client: DK.commit now fails if the commit does not exists (instead of failing later when the commit is used) (#565, @samoht)

datakit-client-git

• git client: add client bindings using Git directly, without the need for a DataKit server (#559, @samoht)

datakit

• datakit: move all modules under the Datakit namespace. Expose Datakit.Blob, Datakit.Branch, Datakit.Hash, Datakit.Metadata, Datakit.Path forming the base types for DataKit stores. Also expose Datakit.Make (and Datakit.Make_git) to build a DataKit store from an Irmin store (or from a Irmin_git store). Finally, rename the functor to expose a DataKit store into a virtual file-system into Datakit.VFS (#583, @samoht)

• datakit: use irmin 1.2.0 and git 1.11.0 (#556, @samoht)

• datakit: use mtime 1.0 (#560, @samoht)

• datakit: stop using camlzip, switch to decompress (#570, @samoht)

datakit-github

• github: expose PR's owner (#587, @samoht)

datakit-github-bridge

• github bridge: look at the GH token in various places (#577, @samoht)

• github bridge: add the ability to monitor default repositories using the CLI (#577, @samoht)

• github bridge: allow to use git://<path> urls to "connect" to a local Git repo instead of a 9p DataKit server (#577, @samoht). For instance:

  $ datakit-bridge-github -r samoht/test -d git:///tmp/foo --resync 60
  

  will download all the issues and PR into a Git repository /tmp/foo and will keep it up-to-date when changes occur either on GitHub (with a full resync every 60s) or locally by commiting updates in the /tmp/foo Git repository.

datakit-ci

• use redis 0.3.5 (#562, #567, @samoht)

0.10.1 (2017-05-09)

all

• Update to support protocol-9p and protocol-9p-unix 0.11.0 (#547, #549 by @avsm, @samoht)

all

• Rename docker/datakit into moby/datakit (#528, @talex5)

• The Docker images on Hub have moved to datakit: Use docker run datakit/db to run the database (see README.md)

• Use jbuilder to build the project. Total project build time pass from ~1min to less than 10s and identifed a few issues with linking local/global names. For instance Datakit_conduit were depending on datakit-server and it was not clear which version it was linked with (#532, @samoht)

datakit-local-git (new)

• bridge-local-git: add local git bridge (#458, @talex5)

• github: major refactoring to use only one branch in datakit to persist the data and keep the rest in memory otherwise. Also use a stronger model of ownership to decide whether datakit or GitHub is right (#311, @samoht)

datakit

• datakit: update to irmin.0.12.0 to use faster native watch notifications instead of file-system polling and full scanning (#347, @samoht)

• Bindings to the Github events API to get notification on new pull requests (#63, @samoht)

while read PR do echo New PR: $PR echo pending > /db/github.com/docker/datakit/pr/status/test ... done < /db/github.com/docker/datakit/pr/updates ```

• Allow to set the description and urls for pull request status (#64, @samoht)

• Update VFS to report file metadata (#66, @talex5)

• Add stats to file metadata (#66, @talex5)

• Replace "Buffer to small" error with a read of 0 items (#71, @talex5) Linux reads a directory like like:

  • Linux asks us to fill an 8K buffer.

  • We return nearly 8K (must return a whole number of items).

  • Linux asks us to fill the remaining few bytes.

  • We return nothing.

  • Linux flushes its buffer and asks for the next 8K. ... This means we get roughly twice as many roundtrips as needed, but it does work.

• Allow renaming files in a transaction (#73, @talex5)

• Metadata support (executable files and symlinks):

  • creation of executable files

  • creation of symlinks

  • chmod +x works

  • writing preserves the executable flag

  • merging now also merges metadata This appears to be sufficient to build Docker under Datakit (#69, @talex5)

• Don't allow fast-forward to missing commit (#81, @talex5)

• Simplify the Vfs.File.Stream API and use it consistently through the codebase (#83, @samoht)

  • stream files have a state

  • when you open a stream file, you immediately get a line with the current state

  • as long as you keep the file open, you get a newline for every updates

  • you can have multiple reader (e.g. concurrently open files)

  • the writers as "publish" functions in the VFS API, you can have multiple concurrent writers. In that case, the behaviour is similar to condition broadcasts: every reader should receive the updates in the same order.

0.3.0 (2016-04-04)

• Fix a memory leak. This was due to a missing free in the readdir bindings in the upstream Lwt library, see https://github.com/ocsigen/lwt/issues/229 (#57 by @talex5 and @samoht)

• Fix a regression introduced in 0.2.0 where inode numbers were not stable anymore, which broke cp commands (#56 by @talex5)

• Enable verbose mode by setting the DATAKIT_VERBOSE environment variable and turn-on more verbose logging of underlying libraries (#53 by @samoht)

• Replace Irmin views with a more efficient representation which does not keep track of transaction's actions and remove the need for creating temporary dangling commits (#16, #51 by @talex5)

• Backport performance fixes from upstream ocaml-git (#43, #47 by @talex5)

• Minimal integration with the Github PR API using 9p (#42 by @samoht)

~/mnt $ ls github.com/docker/datakit 41 42 ~/mnt $ cat github.com/docker/datakit/pr/41/status/default pending ~/mnt $ echo success > github.com/docker/datakit/pr/41/status/default ```

• Use Astring and Logs (#50, #43 by @talex5 and @samoht)

0.2.0 (2016-03-18)

• Add support for "Git remotes" in the filesystem (#21, @samoht). Now you can:

  ~/mnt $ cd remotes
  ~/mnt/remotes $ mkdir origin
  ~/mnt/remotes $ echo https://github.com/docker/datakit > origin/url
  ~/mnt/remotes $ echo master > origin/fetch
  ~/mnt/remotes $ cat origin/head
  4b6557542ec9cc578d5fe09b664110ba3b68e2c2
