CHANGES:

Added

• irmin

  • Add Conf.pp and Conf.equal to print and compare configuration values
    (Add Conf.pp and Conf.equal mirage/irmin#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. (irmin: allow to keep tree caches after a commit mirage/irmin#2225, @samoht)

• irmin-pack

  • Add configuration option, lower_root, to specify a path for archiving data
    during a GC. (irmin-pack: add lower_root config for lower layer mirage/irmin#2177, @metanivek)
  • Add is_split_allowed to check if a store allows split. (irmin-pack: disallow split when gc is disallowed mirage/irmin#2175, @metanivek)
  • Add add_volume to allow creating new empty volume in lower layer. (irmin-pack: initial integration of lower into store api mirage/irmin#2188,
    @metanivek)
  • Add a behaviour function to the GC to check wether the GC will archive or
    delete data. (irmin-pack: introduce shallow GC API changes, V0 GC compatibility mirage/irmin#2190, @Firobe)
  • Add a migration on open_rw to move the data to the lower_root if
    the configuration was enabled (irmin-pack: fast migration to lower by copy mirage/irmin#2205, @art-w)

Changed

• irmin
  • Expose type equality for Schema.Info to avoid defining the info function
    multiple times when using similar stores (irmin: expose info type equality mirage/irmin#2189, more info type equality mirage/irmin#2193, @samoht)
• irmin-pack
  • GC now changes its behaviour depending on the presence of a lower layer.
    (irmin-pack: introduce shallow GC API changes, V0 GC compatibility mirage/irmin#2190, @Firobe)
  • Split now raises an exception if it is not allowed. It is not allowed on
    stores that do not allow GC. (irmin-pack: disallow split when gc is disallowed mirage/irmin#2175, @metanivek)
  • GC now supports stores imported V1/V2 stores, in presence of a lower layer
    only. (irmin-pack: introduce shallow GC API changes, V0 GC compatibility mirage/irmin#2190, @art-w, @Firobe)
  • Upgrade on-disk format to version 5. (irmin-pack: add V5 version mirage/irmin#2184, @metanivek)
  • Archive to lower volume does not copy orphaned commits. (irmin-pack: archive only reachable objects mirage/irmin#2215, @art-w)

Fixed

• irmin-pack
  • Unhandled exceptions in GC worker process are now reported as a failure
    (irmin-pack: treat unhandled exception in async task as a failure mirage/irmin#2163, @metanivek)
  • Fix the silent mode for the integrity checks. (irmin-pack: fix silent mode for integrity checks mirage/irmin#2179, @icristescu)
  • Fix file descriptor leak caused by mmap. (irmin-pack: no mmap syscall mirage/irmin#2232, @art-w)

[metanivek]

I think the CI failures are unrelated to this release. I did retry them, but they failed in the same way, unfortunately.

[raphael-proust]

I've restarted the failing CI jobs which all look like transient errors (network resolution timeouts).
