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)
  • Add create_one_commit_store to create a new store from the existing one,
    containing only one commit. (#2125, @icristescu)

Changed

• irmin-pack
  • Upgraded on-disk format to version 4. (#2110, @icristescu)
  • Detecting control file corruption with a checksum (#2119, @art-w)
  • Change on-disk layout of the suffix from a single file to a multiple,
    chunked file design (#2115, @metanivek)
  • Modify GC to work with new chunked suffix. See examples/gc.ml for a
    demonstration of how it works with the new split function. (#2126,
    @metanivek)

Fixed

3.4.3

CHANGES:

Fixed

• irmin-pack
  • Fix read-only opening flags of mapping for read-only opening of stores that
    do not have read-write rights on the files. (#2121, @Ngoguey42)

3.4.2

CHANGES:

Added

• irmin

  • Add test_set_and_get* functions to retrieve commit associated with an update to the store (#2075, @patricoferris)

• irmin-graphql

  • Expose test_set_and_get function as a new mutation (#2075, @patricoferris)
  • Add contents_hash function to get a value's hash (#2099, @patricoferris)

• irmin-pack

  • Expose Gc.cancel to abort a running GC (#2101, @art-w)

• irmin-tezos-utils

  • Add package irmin-tezos-utils containing a graphical tool for manual pack
    files analysis. (#1939, @clecat)

Changed

• irmin-pack
  • irmin_pack_mem no longer exposes disk specifics functions (#2081,
    @icristescu)
  • Move unix specific details for Pack_key and Pack_value from irmin-pack
    to irmin-pack.unix (#2084, @metanivek)

Fixed

• irmin-pack

  • Fix bugs in gc related to commits that share the same tree. (#2106,
    @icristescu)
  • Fix the traverse pack files commands in the irmin-tezos CLI to work with
    gced stores. (#1919, @icristescu)

3.4.1

CHANGES:

Added

• irmin

  • Add Storage module for creating custom storage layers (#2047, @metanivek)

• irmin-pack

  • Add Gc.is_allowed (#2076, @icristescu)
  • Add a weight parameter in the LRU implementation to bound
    memory usage (#2050, @samoht)

Changed

• irmin
  • Removed Irmin_unix.set_listen_dir_hook (#2071, @zshipko)

Fixed

• irmin-pack
  • Fix the behaviour of irmin-pack regarding hashes and keys to GCed objects.
    It used to not correctly ignore these entries, which could have resulted in
    various bugs. E.g. the impossibility to append an object that used to be
    dead and that has its hash in index. (#2070, @Ngoguey42)

3.4.0

CHANGES:

Added

• irmin

  • Add Tree.seq to Tree's public API (#1923, @metanivek)

• irmin-fs

  • Add unix subpackage, irmin-fs.unix (#1948, @metanivek)

• irmin-git

  • Add unix subpackage, irmin-git.unix (#1948, @metanivek)

• irmin-graphql

  • Add unix subpackage, irmin-graphql.unix (#1948, @metanivek)

• irmin-http

  • Add unix subpackage, irmin-http.unix (#1948, @metanivek)

• irmin-cli

  • Add new package for irmin command-line tool (#1951, @metanivek)

• irmin-pack

  • Add a garbage collection feature, allowing a user to discard commits older
    than a specified commit. This feature is only enabled for stores that use
    Indexing_strategy.minimal. The primary API is Store.Gc.run,
    Store.Gc.wait, and Store.Gc.is_finished. See examples/gc.ml for a
    demonstration of usage.
  • Add a consistency check for the files on disk when opening store (#2004,
    @icristescu)

Changed

• irmin

  • Replaced Tree.node_fn type with more general Tree.folder type to
    represent the different ways to use Tree.fold (#1918, @metanivek)

• irmin-unix

  • Removed the irmin-unix package. Unix backends are now subpackages of their
    relevant backend (see irmin-fs.unix and irmin-git.unix). The CLI tool is
    in irmin-cli. For common unix utilities, see irmin.unix. (#1953, @metanivek)

• irmin-graphql

  • Updated to graphql.0.14.0 (#1843, @patricoferris, @zshipko)

Fixed

• irmin
  • Fix a bug in Irmin.LRU.clear that disables the cache completly
    after a clear. This is not used in any production code as only
    the GC is clearing LRU so far (#1998, @samoht)

3.3.2

CHANGES:

Fixed

• Add a consistency check for the files on disk when opening store
  (#2004, #2007, #@icristescu)
• Fix irmin-tezos CLI and ./tezos-node storage to work with
  v2 inodes (#1903, @icristescu, @Ngoguey42)

3.3.1

CHANGES:

Fixed

• irmin-pack
  • Fix topology irregularities on disk which may lead to post-gc crashes.
    (#1925, @Ngoguey42, @icristescu)

3.3.0

CHANGES:

Added

• irmin

  • Add Metrics module to describe metric gathering in irmin.
    (#1817, @maiste)
  • Add Repo.config to access config used to create repo
    (#1886, @zshipko)

• irmin-unix

  • Add --plugin flag to load Dynlink plugins that can register new
    contents, hash and store types (#1808, @zshipko)

• irmin-pack

  • Add use_fsync, dict_auto_flush_threshold and
  • suffix_auto_flush_threshold in store configuration. (#1865, @Ngoguey42)
  • Add no_migrate in store configuration. (#1893, @zshipko)

Changed

• irmin-pack
  • Move Irmin_pack.Pack_store.Indexing_strategy to
    Irmin_pack.Indexing_strategy and the rest of Pack_store
    to Irmin_pack_unix (#1833, @Ngoguey42)
  • Different repos opened using the same store module no longer share caches
    and file descriptors (#1852, @Ngoguey42)
  • Snapshot.Import.close requires a repo as additional argument (#1872,
    @icristescu)
  • Upgraded on-disk format to version 3 to support better synchronisation
    mechanism between readwrite and readonly instances. This change is not
    backwards-compatible with existing stores using irmin-pack.x.x < 3.3.0
    versions. A migration done by the readwrite instance is necessary to open
    older stores with irmin-pack.3.3.0. It is not forwards compatible. (#1865)
  • Rename Store.sync to Store.reload (#1900, @Ngoguey42).
  • Add Pack_error exception that centralizes many error cases alongside
    RO_not_allowed and Unix.Unix_error (#1899, @Ngoguey42)

Fixed

• irmin-pack

  • Allow snapshot export to work on indexed root nodes (#1845, @icristescu)

• irmin

  • Fix Tree.export for nodes exported twice using different repos. (#1795,
    @Ngoguey42)

3.2.2

CHANGES:

Fixed

• irmin-pack
  • Allow snapshot export to work on indexed root nodes (#1846, @icristescu)

3.2.1

CHANGES:

• Support all version of cmdliner (#1803, @samoht)
