libgit2 v0.26.0 RC1

on GitHub

This is the first release candidate of libgit2 v0.26.0.

Notable changes since v0.25:

Changes or improvements

• Support for opening, creating and modifying worktrees.

• We can now detect SHA1 collisions resulting from the SHAttered attack. These
  checks can be enabled at build time via -DUSE_SHA1DC.

• Fix for missing implementation of git_merge_driver_source getters.

• Fix for installed pkg-config file being broken when the prefix contains
  spaces.

• We now detect when the hashsum of on-disk objects does not match their
  expected hashsum.

• We now support open-ended ranges (e.g. "master..", "...master") in our
  revision range parsing code.

• We now correctly compute ignores with leading "/" in subdirectories.

• We now optionally call fsync on loose objects, packfiles and their indexes,
  loose references and packed reference files.

• We can now build against OpenSSL v1.1 and against LibreSSL.

• GIT_MERGE_OPTIONS_INIT now includes a setting to perform rename detection.
  This aligns this structure with the default by git_merge and
  git_merge_trees when NULL was provided for the options.

• Improvements for reading index v4 files.

• Perform additional retries for filesystem operations on Windows when files
  are temporarily locked by other processes.

API additions

• New family of functions to handle worktrees:

  • git_worktree_list() lets you look up worktrees for a repository.
  • git_worktree_lookup() lets you get a specific worktree.
  • git_worktree_open_from_repository() lets you get the associated worktree
    of a repository.
    a worktree.
  • git_worktree_add lets you create new worktrees.
  • git_worktree_prune lets you remove worktrees from disk.
  • git_worktree_lock() and git_worktree_unlock() let you lock
    respectively unlock a worktree.
  • git_repository_open_from_worktree() lets you open a repository via
  • git_repository_head_for_worktree() lets you get the current HEAD for a
    linked worktree.
  • git_repository_head_detached_for_worktree() lets you check whether a
    linked worktree is in detached HEAD mode.

• git_repository_item_path() lets you retrieve paths for various repository
  files.

• git_repository_commondir() lets you retrieve the common directory of a
  repository.

• git_branch_is_checked_out() allows you to check whether a branch is checked
  out in a repository or any of its worktrees.

• git_repository_submodule_cache_all() and
  git_repository_submodule_cache_clear() functions allow you to prime or clear
  the submodule cache of a repository.

• You can disable strict hash verifications via the
  GIT_OPT_ENABLE_STRICT_HASH_VERIFICATION option with git_libgit2_opts().

• You can enable us calling fsync for various files inside the ".git"
  directory by setting the GIT_OPT_ENABLE_FSYNC_GITDIR option with
  git_libgit2_opts().

• You can now enable "offset deltas" when creating packfiles and negotiating
  packfiles with a remote server by setting GIT_OPT_ENABLE_OFS_DELTA option
  with GIT_libgit2_opts().

• You can now set the default share mode on Windows for opening files using
  GIT_OPT_SET_WINDOWS_SHAREMODE option with git_libgit2_opts().
  You can query the current share mode with GIT_OPT_GET_WINDOWS_SHAREMODE.

• `git_transport_smart_proxy_options()' enables you to get the proxy options for
  smart transports.

Breaking API changes

• clone_checkout_strategy has been removed from
  git_submodule_update_option. The checkout strategy used to clone will
  be the same strategy specified in checkout_opts.
