3.9.0

CHANGES:

Added

• irmin-server
  • Added irmin-server package (#2031, @zshipko)
• irmin-client
  • Added irmin-client package to connect to irmin-server instances (#2031,
    @zshipko)
• irmin
  • Add pretty printers for Commit, Tree, Info, Status, Branch when
    using utop (@metanivek, #1839)

Fixed

• irmin-pack
  • Fix index integrity check for v3 stores (#2267, @metanivek)

Removed

• irmin-http
  • Removed irmin-http since it is not compatible with generic keys.
    irmin-grapqhl or irmin-server should be used instead. (#1902, @zshipko)
• irmin
  • Removed stream proofs. We now only have Merkle tree proofs. This simplifies
    the maintenance of that part of the code, as ensuring the correct order of
    cached IO operations was tricky for stream proofs (#2275, @samoht)

Changed

• irmin-git
  • Moved lower bounds to git.3.14.0 to use new function (#2277, @metanivek)

3.8.0

CHANGES:

Added

• irmin

  • Change behavior of Irmin.Conf.key to disallow duplicate key names by
    default. Add allow_duplicate optional argument to override. (#2252,
    @metanivek)

• irmin-pack

  • Add maximum memory as an alternative configuration option, lru_max_memory,
    for setting LRU capacity. (@metanivek, #2254)

Changed

• irmin

  • Lower bound for mtime is now 2.0.0 (#2166, @patricoferris)

• irmin-mirage-git

  • Lower bound for mirage-kv is now 6.0.0 (#2256, @metanivek)

Fixed

• irmin-cli
  • Changed --store irf to --store fs to align the CLI with what is
    published on the Irmin website (#2243, @wyn)

CHANGES:

Fixed

• irmin

  • Fix performance issue in Tree.length (#2258, @art-w)

  • Fix snapshot export when using lower layer (#2257, @metanivek)

3.7.1

CHANGES:

Fixed

• irmin-pack
  • Fix issue when migrating v2 stores to use lower layer (@metanivek, #2241)

    (@metanivek, #2242)

3.7.0

CHANGES:

Added

• irmin

  • Add Conf.pp and Conf.equal to print and compare configuration values
    (#2227, @samoht)
  • Add a clear optional arguments to all function that adds a new commit:
    Commit.v, set, set_tree, remove, test_and_set,
    test_and_set_tree, test_set_and_get, test_set_and_get_tree, merge,
    merge_tree and with_tree. This new argument allows to control whether
    the tree caches are cleared up after objects are exported to disk during
    the commit. (#2225, @samoht)

• irmin-pack

  • Add configuration option, lower_root, to specify a path for archiving data
    during a GC. (#2177, @metanivek)
  • Add is_split_allowed to check if a store allows split. (#2175, @metanivek)
  • Add add_volume to allow creating new empty volume in lower layer. (#2188,

    delete data. (#2190, @Firobe)
  • Add a migration on open_rw to move the data to the lower_root if
    the configuration was enabled (#2205, @art-w)

Changed

• irmin
  • Expose type equality for Schema.Info to avoid defining the info function
    multiple times when using similar stores (#2189, #2193, @samoht)
• irmin-pack
  • GC now changes its behaviour depending on the presence of a lower layer.
    (#2190, @Firobe)
  • Split now raises an exception if it is not allowed. It is not allowed on
    stores that do not allow GC. (#2175, @metanivek)
  • GC now supports stores imported V1/V2 stores, in presence of a lower layer
    only. (#2190, @art-w, @Firobe)
  • Upgrade on-disk format to version 5. (#2184, @metanivek)
  • Archive to lower volume does not copy orphaned commits. (#2215, @art-w)

    (#2163, @metanivek)
  • Fix the silent mode for the integrity checks. (#2179, @icristescu)

3.6.0

CHANGES:

3.5.1

CHANGES:

    strategy. (#2160, @icristescu)

3.5.0

CHANGES:

Added

• irmin-pack
  • Add Irmin_pack_unix.Stats.Latest_gc which is now the parameter of GC's
    finished callback (#2089, @Ngoguey42)
  • Add Gc.oldest_live_commit which returns the key of the commit on which the
    latest gc was called on. (#2110, @icristescu)
  • Add split to create a new suffix chunk. Subsequent writes will append to
    this chunk until split is called again. (#2118, @icristescu)

    containing only one commit. (#2125, @icristescu)

    chunked file design (#2115, @metanivek)

    @metanivek)
