CHANGES:

This release contains 2.6.0 plus the changes described in 2.5.4.

CHANGES:

Fixed

• irmin-pack

  • Revert a patch introduced in 2.3.0 which was calling Index.try_merge.
    This function was supposed to hint index to schedule merges after
    every commit. However, Index.try_merge is buggy and stacks merges
    which causes the node to block and wait for any existing merge to
    complete. We will revisit that feature in future once we fix
    Index.try_merge (#1409, @craigfe)

• irmin

  • Fix peformance issue in Tree.update_tree and Tree.add_tree for
    large directories (#1315, @Ngoguey42)

Added

• irmin-pack
  • Expose internal inode trees (#1273, @mattiasdrp, @samoht)

CHANGES:

Fixed

• irmin

  • Fix stack overflow exception when working with wide trees (#1313, @zshipko)

  • Tree.of_concrete now prunes empty subdirectories, and raises
    Invalid_argument if the input contains duplicate bindings. (#1385,
    @craigfe)

• irmin-chunk

  • Use the pre_hash function to compute entry keys instead of
    their raw binary representation (#1308, @samoht)

Changed

• irmin-git
  • Upgrade irmin-git with git.3.4.0. (#1392, @dinosaure)

CHANGES:

Fixed

• irmin
  • Fixed a bug causing equality functions derived from Store.tree_t to return
    false-negatives. (#1371, @craigfe)

Added

• irmin
  • Add Store.Tree.is_empty. (#1373, @craigfe)

CHANGES:

Fixed

• irmin

  • The Tree.update_tree and Tree.add_tree functions now interpret adding
    an empty subtree as a remove operation, rather than adding an empty
    directory. (#1335, @craigfe)

• irmin-pack

  • Fix a performance regression where all caches where always cleaned by
    Store.sync when using the V1 format (#1360, @samoht)

CHANGES:

• irmin-git
  • Use the last version of git 3.3.0. It fixes a bug about trailing LF on
    message. For Irmin users, it should not change anything (#1301, @dinosaure,
    @craigfe)

CHANGES:

Changed

• irmin

  • Store.Tree.remove is now much faster when operating on large directories.
    The commits following removals are also much faster. (#1289, @Ngoguey42)

  • Changed Store.Tree.{of_hash, shallow} to take kinded hashes, allowing the
    creation of unforced contents values. (#1285, @craigfe)

  • Changed Tree.destruct to return lazy contents values, which may be forced
    with Tree.Contents.force. (#1285, @craigfe)

• irmin-bench

  • New features in benchmarks for tree operations (#1269, @Ngoguey42)
