1.11.3 (2017-11-20)

  • add ocplib-endian to dependencies of git (#233, @hannesm)

1.11.2 (2017-08-02)

  • Update to conduit.1.0 and cohttp.0.99 (#226, @samoht)

1.11.1 (2017-07-25)

  • [git-unix] Fix linking issue of the ogit binary on some package
    configurations (#225, @samoht)

1.11.0 (2016-06-01)

  • Add ogit add-commit-parent to add a new parent to a given commit
    (#208, @samoht)

  • port to jbuilder (#209, @samoht)

  • port to mtime 1.0 (#212, @dinosaure and @samoht)

  • Improve API docs (#201, @olleolleolle)

  • Compat with cmdliner 1.0 (#202, @samoht)

  • Fix typos and links in docs (@smeruelo and @olleolleolle)

1.10.0 (2017-02-15)

  • Adapt to Mirage3 (@samoht, @avsm, @yomimono, @hannesm)

  • Add IO.test_and_set to automatically update references (#185, @samoht)

  • Better Windows support (#187, @samoht)

    • unix: Translate Git references into valid Windows filenames

    • fix/work-around upstream issues to make the tests pass on Windows

  • Split the package into 4 packages: git, git-http, git-unix and
    git-mirage (#189, @samoht)

1.9.3 (2016-11-09)

  • Turn a bunch of info message into debug statements (#169, @samoht)

1.9.2 (2016-10-16)

  • Do not depend on ocaml-crc anymore: less C code means, easier to
    port to other MirageOS backends (#166, @g2p)

1.9.1 (2016-10-04)

  • Cache all intermediate values when expending packed values. This
    speeds-up pack access quite a lot in practice, especially when the
    pack files are big (#163)

1.9.0 (2016-09-30)

  • Use safe-string (#160, @samoht)

  • Support camlzip 1.06 (#160, @samoht)

1.8.0 (2016-05-03)

  • References can point to non-commit hashes (#123, @samoht)

  • Rename Git.SHA into Git.Hash (@samoht)

  • Remove Git.Sync.populate but add Git.Sync.clone to replace the
    previous fetch+populate (#122, @samoht)

  • Fix the API so that references can point to any kind of hashes (#123, @samoht)

  • Fix duplicated references when mixing packed and loose references
    (#124, @samoht)

  • Use astring, logs and fmt (@samoht)

  • Add Store.size. Before, the only way to get the size of a file was to
    decompress the whole thing. The main win comes from getting the size of raw
    packed objects without decompressing. (#143, @talex5)

  • Workaround a memory leak in lwt: See ocsigen/lwt#229, which caused
    IO.rec_file and thus the watch mechanism on Unix to leak memory
    (#146, @samoht)

  • Fix performance regression when reading large files (#147, @chambart)

1.7.3 (2016-02-19)

  • Git_unix now works on MinGW

1.7.2 (2016-01-21)

  • Do not mmap files, as there is no way to easily control the unmap
    of bigarrays. This remove EMFILE errors under load (#133, @talex5)

  • Fix comparison of entries in the index file. This fix a random issue
    which might happen when entries in a pack file are checkout and
    updated (@samoht)

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).

    • Add ogit clone --no-checkout and make ogit clone --bare more similar
      to the same git command.

  • 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.

  • Add an opam file for the mirage-git package.

1.6.0 (2015-07-11)

  • Allow some references to contain pointer to other references (#96)

  • Improve the support for 32bit architectures (#97)

  • Add Reference.pp_head_contents and Reference.equal_head_contents.

  • Remove Store.clear and replace it by Memory.clear, Memory.clear_all
    and FS.remove. This let users have a finer control over the memory
    consumption of the program over time (related to #90)

  • Rename all pp_hum functions into pp.

  • Fix regression in Sync.fetch and add unit-tests (running only in slow mode).

  • Fix reading of .git/HEAD when the contents is a commit hash.

  • Depends on Stringext for all the extra string function needed.

1.5.3 (2015-07-10)

  • Fix listing of packed references (#98)

    a directory name becomes a file name (#87)

  • Fix the order of entries in the tree objects (#86)

1.5.0 (2015-06-12)

  • Compatibility with cohttp.0.18. (#80 by @rgrinberg)

  • Simplify the mirage sync API to use conduit 0.8.4 (breaking API changes)

  • Change ogit cat-file to behave exactly as git cat-file
    The previous command is renamed to ogit cat (#75 by @codinuum)

  • ogit now supports short hashes instead of full SHA1 (#75 by @codinuum)

  • Add Git.Pack.Raw.read to read raw pack files (#75 by @codinuum)

  • Git.Pack_index.t now uses a cache of entries. This is more efficient
    than the previous representation (#75 by @codinuum)

  • Add Git.Pack_index.mem to find an entry in the pack index cache
    (#75 by @codinuum)

  • Add Git.Pack_index.find_offset to find an offset in the pack index
    cache (#75 by @codinuum)

  • Add Git.Packed_value.to_value to unpack a value stored in a pack file
    (#75 by @codinuum)

  • Support synchronisation for MirageOS unikernels (#70)

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

    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)

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.

  • 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

  • Depend the implementation of patience diff in pure OCaml (unused for now)

1.0.2: (2014-04-19)

  • Catch, improve and propagate Zlib inflation errors (which usually pop-ups
    on incomplete files)

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)
