• breaking changes Commit object must have a double LF to separate the header and the body. This format changes hashes of commit and invalid old commits generated by ocaml-git. It seems that on the Git side, the format is not fully respected - and it's why Git did not complain about that on our tests for a long time.

  However, git fsck does this check and an HTTP push to GitHub run git fsck at the end. To be able to push (or run our unikernel over HTTP/S), we must generate right commits.

  So, we advise users to make a fake commit with Git (git commit --allow-empty -m.) on repositories used by ocaml-git and fetch it with depth:1. Otherwise, this new version of ocaml-git will refute older commits - due to the inherent isomorphism between decoder/encoder in ocaml-git.

  For Irmin users, this breaking changes does not change anything when irmin reformats correctly the message to put the second LF. However, a breaking change exists on the API level when the Git commit (and a Git tag) expects a string option now (instead of a simple `string).

1.7.3 (2016-02-19)

• Git_unix now works on MinGW

1.7.1 (2015-08-10)

• Support cohtpp 0.19.1. (#119, @rgrinberg)
• Revert API break for the Sync functor. Now still takes only a Store.S as parameter. (#120)

1.7.0 (2015-08-06)

• Changes to the Search API:

  • Remove find_exn
  • the type t has a new case Tree_root to represent tree roots
  • the type path is now structured (not a list of strings anymore). this removes the confusing semantics of empty strings in paths.

• Changes to the Global_graph API:

  • closure takes an optional full argument to work over commit objects only
  • All the arguments of pack are labelled and its result type has changed.
  • Add keys to return the topological sort of keys in the graph.

• Improve the size of pack files received when fetching (#115)

  • advertise the fact that ocaml-git clients support ofs-delta and thin-pack
  • Compute a minimal set of haves to send to the server after the discovery phase, where we already know all the server references (#114)
• Unpack shallow pack files after a fetch
• Full support for shallow packs (#81)
• During fetch, we now respect the "allow-reachable-sha1-in-want" server (non-)capability. A proper error is reported to the client if that's not the case.
• Parametrize the codebase over the Inflate implementation. Useful to change the inflate algorithm (or to not use any at all, which would be what we want for big files and/or for efficient writes) and to simplify the port to other backends. Store.S implementations now expose their Inflate implementation.
• Parametrize the codebase over the SHA implementation. Useful to change the SHA algorihm (the unix backend provides SHA256) or simplify the port to other backends (the mirage backend uses a pure OCaml implementation extracted from uuidm). Store.S implementations now expose their Digest implementation (#68)

• Better sync API (#113)

  • Change the arguments of Sync.fetch
  • Remove Sync.clone
  • Add Sync.populate to be called after a fetch to properly populate the local Git repository (similar to what git clone does).

• Support Github http(s) URLs without .git (#111)
• Add a dot_git optional parameter to Store.create to specify where the Git metadata should be stored (default is still <root>/.git). This is useful to properly support bare repositories (#110)
• Full support for 32 bit platform (ie. continue the patch started in 1.6.2).
• Rework the Git.Pack and Git.Pack_index API to speed-up random access.
• Add a Git.SHA.Array module to work with contiguous arrays of SHA1.
• Rename Git.SHA.lenght to Git.SHA.hex_length to avoid confusion.
• Expose Git.SHA.of_short_hex to create short hashes. Git.SHA.of_hex now only accept 40 characters hexa-decimal strings.
• Improve the output of ogit clone by showing progress when the pack file is downloaded and when the delta are resolved.

1.6.2 (2015-07-16)

• Support 32 bit platform by avoiding creating large strings. This also improve the performance of reading and synchronizin large pack files (#103, #105 @gregtatcam)

1.6.1 (2015-07-14)

• Fix a bug in ogit pull using the smart HTTP protocol when the HTTP temporary buffer could sometimes be overfill.
• Avoid closing twice the same fd in the smart HTTP protocol.
• Avoid the GC to close a fd while we are still using a channel built on top of it -- this affects the smart HTTP protocol only.

1.4.11 (2015-03-11)

• Fix multi round-trips in the smart HTTP protocol. This fixes depth-limited clones (#71) and fetches.
• Create the git.http library for abstracting away bits of the smart HTTP protocol.
• Add User-Agent in the headers of the smart HTTP protocol. This makes bitbucket.org happy. (#66, patch from @vklquevs)

1.4.10 (2015-02-05)

• Fix support for the smart HTTP protocol (report by @talex5, mirage/irmin#138)

1.4.9 (2015-02-04)

• Remove the OGITTMPDIR and alway store temp files under git/tmp (mirage/irmin#132)

1.4.8 (2015-02-04)

• Fix LRU cache: SHA1 should be unique in the cache (regression introduced in 1.4.3). This was causing confusing read results under load.
• Reading objects now updates the LRU cache
• Fix a regression in ogit cat-file which were displaying nothing for small objects.

1.4.7 (2015-02-03)

• Fix the filesystem updates for non-bare repositories (reported by @avsm)
• Git.write_index now takes an optional index argument
• Index entries should be fixed alphabetically
• Remove raw printf (#60)
• More flexibility on where to write temp files. The directory name can be configured by write calls, and the default is OGITTMPDIR if set, then Filename.get_temp_dir_name -- as it was in 1.4.5, see #51

1.4.6 (2015-01-29)

• Expose Git.Value.Cache.set_size to change the LRU cache size
• Reduce the default LRU cache size (in 1.4.4 it was set to 64k, now it's 512)
• More precise type for commit dates
• Add git.top to load toplevel printers for Git values

1.4.5 (2015-01-19)

• Support packed-refs files, to read references packed by git gc (reported by Gregory Tsipenyuk)
• Fix the filesystem backend when TMPDIR is not on the same partition as the Git repository (#51, patch from @vklquevs)

1.4.4 (2015-01-12)

• Support the smart HTTP Git protocol (#26)
• Best-effort creation of files when expanding the index into the filesystem: Skip the invalid filenames and continue. Users are expected to sanitize their filenames if they want to use a non-bare repository (#11)
• Overwrite changed file when expanding the index into the filesystem (#4)
• Do not recompute the hash of blob files when expanding the index into the filesystem. This help fixing a speed issue with non-bare repo with lots of file.
• Rename {write,read}_cache to {write,read}_index
• Rename Cache to Index
• Expose the protocol capabilities to the client
• Support side-band-64k protocol capability (#44)
• Fix support for git+ssh (#39)
• Expose zlib compression level (#41)
• Maintain a cache of opened files (#29, Pierre Chambart)

1.4.3 (2014-12-19)

• Fix regression introduced in 1.4.3 appearing when synchronising big repositories (#38)
• Fix concurrent read/write by using an atomic rename (#35)
• Tree objects can also point to commits (@codinuum)
• Reduce allocation (@codinuum)
• Use LRU cache instead of an unbounde Hashtbl (code imported for Simon Cruanes's CCache implementation)
• Remove the crazy unbounded caching in Git.FS. Use the LRU everywhere (#22)
• Fix fd leaking (#29)
• Update to dolog.1.0
• Remove dependency to camlp4
• Remove lots of warnings
• Move Git_unix and Git_mirage in their own subdirs as it was causing issues to oasis (#5, Simon Cruanes)
• Use Bytes instead of String (#5, Simon Cruanes)

1.4.2 (2014-12-14)

• Fix Git_unix.IO.write_file to work on empty files

1.4.1 (2014-12-4)

• Fix ogit --version (#22)
• Expose the backend type
• Expose Git_unix.Sync.IO

1.4.0 (2014-11-20)

• Port to Conduit 0.6.0 API.
• Depend on ocaml-hex

1.3.0 (2014-10-16)

• Remove the dependency on core_kernel
• Use ocaml-nocrypto instead of ocaml-sha1

1.2.0: (2014-06-10)

• Can consume Mirage's V1_LWT.FS signature to generate a persistent store. This allows to store Git repos directly inside raw block devices (no need of filesystem anymore).
• Minor API refactoring to abstract the Unix layer cleanly.
• Expose a filesystem functor to create filesystem backends independent of Unix.
• Simplify the ocamlfind packages: there's only git and git.unix.

1.1.0: (2014-06-02)

• Support for push (not optimized at all)
• Fix the generation of .dot file representing the Git repo
• Fix serialization of executable files in the cache
• Fix reading the total number of keys in a pack index file
• Use ocaml-conduit to set-up connections with remote repositories
• USe ocaml-uri to specify Git Remote Identifiers
• Depend the implementation of patience diff in pure OCaml (unused for now)

1.0.1: (2014-04-10)

• Escape invalid chars in path names
• Do not link with camlp4 when using as a libray

1.0.0: (2014-02-10)

• Support for reading and writing pack indexes
• Support for reading and writing pack files
• Refactor the API: each Git object has now its own file, with a consistent signature
• ogit clone now correctly set-up the cache file (which means that git status and git diff will now work as expected on a repository created by ogit)
• Add ogit read-tree COMMIT
• Add ogit ls-files [--all]
• Support for reading and writing cache files

0.10.2: (2014-01-20)
