CHANGELOG.md

   1 v0.21 + 1
   2 ------
   3
   4 * File unlocks are atomic again via rename. Read-only files on Windows are
   5   made read-write if necessary.
   6
   7 * Share open packfiles across repositories to share descriptors and mmaps.
   8
   9 * Use a map for the treebuilder, making insertion O(1)
  10
  11 * Introduce reference transactions, which allow multiple references to
  12   be locked at the same time and updates be queued. This also allows
  13   us to safely update a reflog with arbitrary contents, as we need to
  14   do for stash.
  15
  16 * The index' tree cache is now filled upon read-tree and write-tree
  17   and the cache is written to disk.
  18
  19 * LF -> CRLF filter refuses to handle mixed-EOL files
  20
  21 * LF -> CRLF filter now runs when * text = auto (with Git for Windows 1.9.4)
  22
  23 * The git_transport structure definition has moved into the sys/transport.h
  24   file.
  25
  26 * The ssh transport supports asking the remote host for accepted
  27   credential types as well as multiple challeges using a single
  28   connection. This requires to know which username you want to connect
  29   as, so this introduces the USERNAME credential type which the ssh
  30   transport will use to ask for the username.
  31
  32 * The build system now accepts an option EMBED_SSH_PATH which when set
  33   tells it to include a copy of libssh2 at the given location. This is
  34   enabled for MSVC.
  35
  36 * libgit2 no longer automatically sets the OpenSSL locking
  37   functions. This is not something which we can know to do. A
  38   last-resort convenience function is provided in sys/openssl.h,
  39   git_openssl_set_locking() which can be used to set the locking.
  40
  41 * The git_transport_register function no longer takes a priority and takes
  42   a URL scheme name (eg "http") instead of a prefix like "http://"
  43
  44 * The git_remote_set_transport function now sets a transport factory function,
  45   rather than a pre-existing transport instance.
  46
  47 * A factory function for ssh has been added which allows to change the
  48   path of the programs to execute for receive-pack and upload-pack on
  49   the server, git_transport_ssh_with_paths.
  50
  51 * git_remote_rename() now takes the repository and the remote's
  52   current name. Accepting a remote indicates we want to change it,
  53   which we only did partially. It is much clearer if we accept a name
  54   and no loaded objects are changed.
  55
  56 * git_remote_delete() now accepts the repository and the remote's name
  57   instead of a loaded remote.
  58
  59 * git_remote_supported_url() has been removed as it has become
  60   essentially useless with rsync-style ssh paths.
  61
  62 * The git_clone_options struct no longer provides the ignore_cert_errors or
  63   remote_name members for remote customization.
  64
  65   Instead, the git_clone_options struct has two new members, remote_cb and
  66   remote_cb_payload, which allow the caller to completely override the remote
  67   creation process. If needed, the caller can use this callback to give their
  68   remote a name other than the default (origin) or disable cert checking.
  69
  70   The remote_callbacks member has been preserved for convenience, although it
  71   is not used when a remote creation callback is supplied.
  72
  73 * The git_clone_options struct now provides repository_cb and
  74   repository_cb_payload to allow the user to create a repository with
  75   custom options.
  76
  77 * The option to ignore certificate errors via git_remote_cert_check()
  78   is no longer present. Instead, git_remote_callbacks has gained a new
  79   entry which lets the user perform their own certificate checks.
  80
  81 * git_clone_into and git_clone_local_into have been removed from the
  82   public API in favour of git_clone callbacks
  83
  84 * Add support for refspecs with the asterisk in the middle of a
  85   pattern.
  86
  87 * Fetching now performs opportunistic updates. To achieve this, we
  88   introduce a difference between active and passive refspecs, which
  89   make git_remote_download and git_remote_fetch to take a list of
  90   resfpecs to be the active list, similarly to how git fetch accepts a
  91   list on the command-line.
  92
  93 * Rename git_remote_load() to git_remote_lookup() to bring it in line
  94   with the rest of the lookup functions.
  95
  96 * git_push_unpack_ok() has been removed and git_push_finish() now
  97   returns an error if the unpacking failed.
  98
  99 * Introduce git_merge_bases() and the git_oidarray type to expose all
 100   merge bases between two commits.
 101
 102 * Introduce git_merge_bases_many() to expose all merge bases between
 103   multiple commits.
 104
 105 * git_merge_head is now git_annotated_commit, to better reflect its usage
 106   for multiple functions (including rebase)
 107
 108 * Introduce rebase functionality (using the merge algorithm only).
 109   Introduce git_rebase_init() to begin a new rebase session,
 110   git_rebase_open() to open an in-progress rebase session,
 111   git_rebase_commit() to commit the current rebase operation,
 112   git_rebase_next() to apply the next rebase operation,
 113   git_rebase_abort() to abort an in-progress rebase and git_rebase_finish()
 114   to complete a rebase operation.
 115
 116 * Introduce git_note_author() and git_note_committer() to get the author
 117   and committer information on a git_note, respectively.
 118
 119 * git_note_create() has changed the position of the notes reference
 120   name to match git_note_remove().
 121
 122 * The THREADSAFE option to build libgit2 with threading support has
 123   been flipped to be on by default.
 124
 125 * The context_lines and interhunk_lines fields in git_diff_options are
 126   now uint32_t instead of uint16_t. This allows to set them to UINT_MAX,
 127   in effect asking for "infinite" context e.g. to iterate over all the
 128   unmodified lines of a diff.
 129
 130 * git_status_file now takes an exact path. Use git_status_list_new if
 131   pathspec searching is needed.
 132
 133 * The fetch behavior of remotes with autotag set to GIT_REMOTE_DOWNLOAD_TAGS_ALL
 134   has been changed to match git 1.9.0 and later. In this mode, libgit2 now
 135   fetches all tags in addition to whatever else needs to be fetched.
 136
 137 * git_threads_init() and git_threads_shutdown() have been renamed to
 138   git_libgit2_init() and git_libgit2_shutdown() to better explain what
 139   their purpose is, as it's grown to be more than just about threads.
 140
 141 * git_libgit2_init() and git_libgit2_shutdown() now return the number of
 142   initializations of the library, so consumers may schedule work on the
 143   first initialization.
 144
 145 * git_treebuilder_new (was git_treebuilder_create) now takes a
 146   repository so that it can query repository configuration.
 147   Subsequently, git_treebuilder_write no longer takes a repository.
 148
 149 * git_treebuilder_create was renamed to git_treebuilder_new to better
 150   reflect it being a constructor rather than something which writes to
 151   disk.
 152
 153 * git_checkout now handles case-changing renames correctly on
 154   case-insensitive filesystems; for example renaming "readme" to "README".
 155
 156 * git_index_name_entrycount() and git_index_reuc_entrycount() now
 157   return size_t instead of unsigned int.
 158
 159 * The search for libssh2 is now done via pkg-config instead of a
 160   custom search of a few directories.
 161
 162 * Add support for core.protectHFS and core.protectNTFS. Add more
 163   validation for filenames which we write such as references.
 164
 165 * The local transport now generates textual progress output like
 166   git-upload-pack does ("counting objects").
