5 | ||
0161e096 SS |
6 | * Updated binary identification in CRLF filtering to avoid false positives in |
7 | UTF-8 files. | |
8 | ||
4d6f55ac ET |
9 | * Rename and copy detection is enabled for small files. |
10 | ||
96b82b11 ET |
11 | * Checkout can now handle an initial checkout of a repository, making |
12 | `GIT_CHECKOUT_SAFE_CREATE` unnecessary for users of clone. | |
13 | ||
659cf202 CMN |
14 | * The signature parameter in the ref-modifying functions has been |
15 | removed. Use `git_repository_set_ident()` and | |
16 | `git_repository_ident()` to override the signature to be used. | |
17 | ||
16bcf0c7 CMN |
18 | ### API additions |
19 | ||
eac773d9 CMN |
20 | * Parsing and retrieving a configuration value as a path is exposed |
21 | via `git_config_parse_path()` and `git_config_get_path()` | |
22 | respectively. | |
23 | ||
659cf202 CMN |
24 | * `git_repository_set_ident()` and `git_repository_ident()` serve to |
25 | set and query which identity will be used when writing to the | |
26 | reflog. | |
27 | ||
9a97f49e CMN |
28 | * `git_config_entry_free()` frees a config entry. |
29 | ||
30 | * `git_config_get_string_buf()` provides a way to safely retrieve a | |
31 | string from a non-snapshot configuration. | |

36 | ||
96b82b11 ET |
37 | * `GIT_CHECKOUT_SAFE_CREATE` has been removed. Most users will generally |
38 | be able to switch to `GIT_CHECKOUT_SAFE`, but if you require missing | |
39 | file handling during checkout, you may now use `GIT_CHECKOUT_SAFE | | |
40 | GIT_CHECKOUT_RECREATE_MISSING`. | |
41 | ||
41513659 CMN |
42 | * The `git_clone_options` and `git_submodule_update_options` |
43 | structures no longer have a `signature` field. | |
44 | ||
45 | * The following functions have removed the signature and/or log message | |
46 | parameters in favour of git-emulating ones. | |
47 | ||
48 | * `git_branch_create()`, `git_branch_move()` | |
49 | * `git_rebase_init()`, `git_rebase_abort()` | |
50 | * `git_reference_symbolic_create_matching()`, | |
51 | `git_reference_symbolic_create()`, `git_reference_create()`, | |
52 | `git_reference_create_matching()`, | |
53 | `git_reference_symbolic_set_target()`, | |
54 | `git_reference_set_target()`, `git_reference_rename()` | |
55 | * `git_remote_update_tips()`, `git_remote_fetch()`, `git_remote_push()` | |
56 | * `git_repository_set_head()`, | |
57 | `git_repository_set_head_detached()`, | |
58 | `git_repository_detach_head()` | |
59 | * `git_reset()` | |
60 | ||
9a97f49e CMN |
61 | * `git_config_get_entry()` now gives back a ref-counted |
62 | `git_config_entry`. You must free it when you no longer need it. | |
63 | ||
64 | * `git_config_get_string()` will return an error if used on a | |
65 | non-snapshot configuration, as there can be no guarantee that the | |
66 | returned pointer is valid. | |

b91f28be | 71 | ### Changes or improvements |
e1fc03c9 | 72 | |
b91f28be | 73 | * `git_signature_new()` now requires a non-empty email address. |
274c3fa6 | 74 | |
b91f28be | 75 | * Use CommonCrypto libraries for SHA-1 calculation on Mac OS X. |
d412165f | 76 | |
b91f28be CMN |
77 | * Disable SSL compression and SSLv2 and SSLv3 ciphers in favor of TLSv1 |
78 | in OpenSSL. | |
d412165f | 79 | |
b91f28be CMN |
80 | * The fetch behavior of remotes with autotag set to `GIT_REMOTE_DOWNLOAD_TAGS_ALL` |
81 | has been changed to match git 1.9.0 and later. In this mode, libgit2 now | |
82 | fetches all tags in addition to whatever else needs to be fetched. | |
c180c065 | 83 | |
b91f28be CMN |
84 | * `git_checkout()` now handles case-changing renames correctly on |
85 | case-insensitive filesystems; for example renaming "readme" to "README". | |
7449c82e | 86 | |
b91f28be CMN |
87 | * The search for libssh2 is now done via pkg-config instead of a |
88 | custom search of a few directories. | |
3753110a | 89 | |
b91f28be CMN |
90 | * Add support for core.protectHFS and core.protectNTFS. Add more |
91 | validation for filenames which we write such as references. | |
5192bcc5 | 92 | |
b91f28be CMN |
93 | * The local transport now generates textual progress output like |
94 | git-upload-pack does ("counting objects"). | |
c180c065 | 95 | |
b91f28be CMN |
96 | * `git_checkout_index()` can now check out an in-memory index that is not |
97 | necessarily the repository's index, so you may check out an index | |
98 | that was produced by git_merge and friends while retaining the cached | |
99 | information. | |
1697cd6f | 100 | |
b91f28be CMN |
101 | * Remove the default timeout for receiving / sending data over HTTP using |
102 | the WinHTTP transport layer. | |
d4256ed5 | 103 | |
b91f28be | 104 | * Add SPNEGO (Kerberos) authentication using GSSAPI on Unix systems. |
46c8f7f8 | 105 | |
b91f28be CMN |
106 | * Provide built-in objects for the empty blob (e69de29) and empty |
107 | tree (4b825dc) objects. | |
262eec23 | 108 | |
b91f28be CMN |
109 | * The index' tree cache is now filled upon read-tree and write-tree |
110 | and the cache is written to disk. | |
0862f617 | 111 | |
b91f28be | 112 | * LF -> CRLF filter refuses to handle mixed-EOL files |
1697cd6f | 113 | |
b91f28be | 114 | * LF -> CRLF filter now runs when * text = auto (with Git for Windows 1.9.4) |
1697cd6f | 115 | |
b91f28be CMN |
116 | * File unlocks are atomic again via rename. Read-only files on Windows are |
117 | made read-write if necessary. | |
d58a64e9 | 118 | |
b91f28be | 119 | * Share open packfiles across repositories to share descriptors and mmaps. |
6812afaf | 120 | |
b91f28be | 121 | * Use a map for the treebuilder, making insertion O(1) |
2cd3cb8e | 122 | |
b91f28be CMN |
123 | * The build system now accepts an option EMBED_SSH_PATH which when set |
124 | tells it to include a copy of libssh2 at the given location. This is | |
125 | enabled for MSVC. | |
9fef46de CMN |
126 | |
127 | * Add support for refspecs with the asterisk in the middle of a | |
128 | pattern. | |
7db0e6ee | 129 | |
c5837cad CMN |
130 | * Fetching now performs opportunistic updates. To achieve this, we |
131 | introduce a difference between active and passive refspecs, which | |
b91f28be | 132 | make `git_remote_download()` and `git_remote_fetch()` to take a list of |
c5837cad CMN |
133 | resfpecs to be the active list, similarly to how git fetch accepts a |
134 | list on the command-line. | |
135 | ||
b91f28be CMN |
136 | * The THREADSAFE option to build libgit2 with threading support has |
137 | been flipped to be on by default. | |
209425ce | 138 | |
b91f28be CMN |
139 | * The remote object has learnt to prune remote-tracking branches. If |
140 | the remote is configured to do so, this will happen via | |
141 | `git_remote_fetch()`. You can also call `git_remote_prune()` after | |
142 | connecting or fetching to perform the prune. | |
143 | ||
144 | ||
145 | ### API additions | |
d524b2d3 | 146 | |
b91f28be CMN |
147 | * Introduce `git_buf_text_is_binary()` and `git_buf_text_contains_nul()` for |
148 | consumers to perform binary detection on a git_buf. | |
149 | ||
150 | * `git_branch_upstream_remote()` has been introduced to provide the | |
151 | branch.<name>.remote configuration value. | |
152 | ||
153 | * Introduce `git_describe_commit()` and `git_describe_workdir()` to provide | |
154 | a description of the current commit (and working tree, respectively) | |
155 | based on the nearest tag or reference | |
156 | ||
157 | * Introduce `git_merge_bases()` and the `git_oidarray` type to expose all | |
7db0e6ee | 158 | merge bases between two commits. |
eca07bcd | 159 | |
b91f28be | 160 | * Introduce `git_merge_bases_many()` to expose all merge bases between |
eca07bcd | 161 | multiple commits. |
67917281 | 162 | |
67917281 | 163 | * Introduce rebase functionality (using the merge algorithm only). |
b91f28be CMN |
164 | Introduce `git_rebase_init()` to begin a new rebase session, |
165 | `git_rebase_open()` to open an in-progress rebase session, | |
166 | `git_rebase_commit()` to commit the current rebase operation, | |
167 | `git_rebase_next()` to apply the next rebase operation, | |
168 | `git_rebase_abort()` to abort an in-progress rebase and `git_rebase_finish()` | |
67917281 ET |
169 | to complete a rebase operation. |
170 | ||
b91f28be CMN |
171 | * Introduce `git_note_author()` and `git_note_committer()` to get the author |
172 | and committer information on a `git_note`, respectively. | |
79b0ae4e | 173 | |
b91f28be CMN |
174 | * A factory function for ssh has been added which allows to change the |
175 | path of the programs to execute for receive-pack and upload-pack on | |
176 | the server, `git_transport_ssh_with_paths()`. | |
21083a71 | 177 | |
b91f28be CMN |
178 | * The ssh transport supports asking the remote host for accepted |
179 | credential types as well as multiple challeges using a single | |
180 | connection. This requires to know which username you want to connect | |
181 | as, so this introduces the USERNAME credential type which the ssh | |
182 | transport will use to ask for the username. | |
d88766c4 | 183 | |
b91f28be CMN |
184 | * The `GIT_EPEEL` error code has been introduced when we cannot peel a tag |
185 | to the requested object type; if the given object otherwise cannot be | |
186 | peeled, `GIT_EINVALIDSPEC` is returned. | |
68182085 | 187 | |
b91f28be CMN |
188 | * Introduce `GIT_REPOSITORY_INIT_RELATIVE_GITLINK` to use relative paths |
189 | when writing gitlinks, as is used by git core for submodules. | |
e284c451 | 190 | |
b91f28be | 191 | * `git_remote_prune()` has been added. See above for description. |
799e22ea | 192 | |
8aba3d47 | 193 | |
b91f28be CMN |
194 | * Introduce reference transactions, which allow multiple references to |
195 | be locked at the same time and updates be queued. This also allows | |
196 | us to safely update a reflog with arbitrary contents, as we need to | |
197 | do for stash. | |
6d91dc53 | 198 | |
b91f28be | 199 | ### API removals |
dce7b1a4 | 200 | |
b91f28be CMN |
201 | * `git_remote_supported_url()` and `git_remote_is_valid_url()` have been |
202 | removed as they have become essentially useless with rsync-style ssh paths. | |
203 | ||
204 | * `git_clone_into()` and `git_clone_local_into()` have been removed from the | |
205 | public API in favour of `git_clone callbacks`. | |
206 | ||
207 | * The option to ignore certificate errors via `git_remote_cert_check()` | |
208 | is no longer present. Instead, `git_remote_callbacks` has gained a new | |
209 | entry which lets the user perform their own certificate checks. | |
210 | ||
211 | ### Breaking API changes | |
208a2c8a | 212 | |
b91f28be CMN |
213 | * `git_cherry_pick()` is now `git_cherrypick()`. |
214 | ||
215 | * The `git_submodule_update()` function was renamed to | |
216 | `git_submodule_update_strategy()`. `git_submodule_update()` is now used to | |
217 | provide functionalty similar to "git submodule update". | |
218 | ||
219 | * `git_treebuilder_create()` was renamed to `git_treebuilder_new()` to better | |
208a2c8a CMN |
220 | reflect it being a constructor rather than something which writes to |
221 | disk. | |
40d79154 | 222 | |
b91f28be CMN |
223 | * `git_treebuilder_new()` (was `git_treebuilder_create()`) now takes a |
224 | repository so that it can query repository configuration. | |
225 | Subsequently, `git_treebuilder_write()` no longer takes a repository. | |
aad27e6e | 226 | |
b91f28be CMN |
227 | * `git_threads_init()` and `git_threads_shutdown()` have been renamed to |
228 | `git_libgit2_init()` and `git_libgit2_shutdown()` to better explain what | |
229 | their purpose is, as it's grown to be more than just about threads. | |
aad27e6e | 230 | |
b91f28be CMN |
231 | * `git_libgit2_init()` and `git_libgit2_shutdown()` now return the number of |
232 | initializations of the library, so consumers may schedule work on the | |
233 | first initialization. | |
aad27e6e | 234 | |
b91f28be CMN |
235 | * The `git_transport_register()` function no longer takes a priority and takes |
236 | a URL scheme name (eg "http") instead of a prefix like "http://" | |
aad27e6e | 237 | |
b91f28be CMN |
238 | * `git_index_name_entrycount()` and `git_index_reuc_entrycount()` now |
239 | return size_t instead of unsigned int. | |
9d1f97df | 240 | |
b91f28be CMN |
241 | * The `context_lines` and `interhunk_lines` fields in `git_diff`_options are |
242 | now `uint32_t` instead of `uint16_t`. This allows to set them to `UINT_MAX`, | |
243 | in effect asking for "infinite" context e.g. to iterate over all the | |
244 | unmodified lines of a diff. | |
974d21c8 | 245 | |
b91f28be CMN |
246 | * `git_status_file()` now takes an exact path. Use `git_status_list_new()` if |
247 | pathspec searching is needed. | |
974d21c8 | 248 | |
b91f28be CMN |
249 | * `git_note_create()` has changed the position of the notes reference |
250 | name to match `git_note_remove()`. | |
974d21c8 | 251 | |
b91f28be CMN |
252 | * Rename `git_remote_load()` to `git_remote_lookup()` to bring it in line |
253 | with the rest of the lookup functions. | |
974d21c8 | 254 | |
b91f28be CMN |
255 | * `git_remote_rename()` now takes the repository and the remote's |
256 | current name. Accepting a remote indicates we want to change it, | |
257 | which we only did partially. It is much clearer if we accept a name | |
258 | and no loaded objects are changed. | |
974d21c8 | 259 | |
b91f28be CMN |
260 | * `git_remote_delete()` now accepts the repository and the remote's name |
261 | instead of a loaded remote. | |
974d21c8 | 262 | |
b91f28be CMN |
263 | * `git_merge_head` is now `git_annotated_commit`, to better reflect its usage |
264 | for multiple functions (including rebase) | |
974d21c8 | 265 | |
b91f28be CMN |
266 | * The `git_clone_options` struct no longer provides the `ignore_cert_errors` or |
267 | `remote_name` members for remote customization. | |
974d21c8 | 268 | |
b91f28be CMN |
269 | Instead, the `git_clone_options` struct has two new members, `remote_cb` and |
270 | `remote_cb_payload`, which allow the caller to completely override the remote | |
271 | creation process. If needed, the caller can use this callback to give their | |
272 | remote a name other than the default (origin) or disable cert checking. | |
974d21c8 | 273 | |
b91f28be CMN |
274 | The `remote_callbacks` member has been preserved for convenience, although it |
275 | is not used when a remote creation callback is supplied. | |
974d21c8 | 276 | |
b91f28be CMN |
277 | * The `git_clone`_options struct now provides `repository_cb` and |
278 | `repository_cb_payload` to allow the user to create a repository with | |
279 | custom options. | |
974d21c8 | 280 | |
b91f28be CMN |
281 | * The `git_push` struct to perform a push has been replaced with |
282 | `git_remote_upload()`. The refspecs and options are passed as a | |
283 | function argument. `git_push_update_tips()` is now also | |
284 | `git_remote_update_tips()` and the callbacks are in the same struct as | |
285 | the rest. | |
974d21c8 | 286 | |
b91f28be CMN |
287 | * The `git_remote_set_transport()` function now sets a transport factory function, |
288 | rather than a pre-existing transport instance. | |
61cd037e | 289 | |
b91f28be CMN |
290 | * The `git_transport` structure definition has moved into the sys/transport.h |
291 | file. | |
292 | ||
293 | * libgit2 no longer automatically sets the OpenSSL locking | |
294 | functions. This is not something which we can know to do. A | |
295 | last-resort convenience function is provided in sys/openssl.h, | |
296 | `git_openssl_set_locking()` which can be used to set the locking. |
