4 | ### Changes or improvements |
5 | ||
70b0f128 JG |
6 | * Patience and minimal diff drivers can now be used for merges. |
7 | ||
8 | * Merges can now ignore whitespace changes. | |
9 | ||
0161e096 SS |
10 | * Updated binary identification in CRLF filtering to avoid false positives in |
11 | UTF-8 files. | |
12 | ||
4d6f55ac ET |
13 | * Rename and copy detection is enabled for small files. |
14 | ||
96b82b11 ET |
15 | * Checkout can now handle an initial checkout of a repository, making |
16 | `GIT_CHECKOUT_SAFE_CREATE` unnecessary for users of clone. | |
17 | ||
659cf202 CMN |
18 | * The signature parameter in the ref-modifying functions has been |
19 | removed. Use `git_repository_set_ident()` and | |
20 | `git_repository_ident()` to override the signature to be used. | |
21 | ||
0ef54a63 CMN |
22 | * The local transport now auto-scales the number of threads to use |
23 | when creating the packfile instead of sticking to one. | |
24 | ||
8acf058f CMN |
25 | * Reference renaming now uses the right id for the old value. |
26 | ||
27 | * The annotated version of branch creation, HEAD detaching and reset | |
28 | allow for specifying the expression from the user to be put into the | |
29 | reflog. | |
30 | ||
aa9bb425 | 31 | * `git_rebase_commit` now returns `GIT_EUNMERGED` when you attempt to |
eaf0d688 ET |
32 | commit with unstaged changes. |
33 | ||
85247df0 CMN |
34 | * On Mac OS X, we now use SecureTransport to provide the cryptographic |
35 | support for HTTPS connections insead of OpenSSL. | |
36 | ||
1f1f5c63 ET |
37 | * Checkout can now accept an index for the baseline computations via the |
38 | `baseline_index` member. | |
39 | ||
b1ae3e53 CMN |
40 | * The configuration for fetching is no longer stored inside the |
41 | `git_remote` struct but has been moved to a `git_fetch_options`. The | |
42 | remote functions now take these options or the callbacks instead of | |
43 | setting them beforehand. | |
44 | ||
874cc35a CMN |
45 | * The index now uses diffs for `add_all()` and `update_all()` which |
46 | gives it a speed boost and closer semantics to git. | |
47 | ||
e3435673 CMN |
48 | * The ssh transport now reports the stderr output from the server as |
49 | the error message, which allows you to get the "repository not | |
50 | found" messages. | |
51 | ||
b1ae3e53 | 52 | |
16bcf0c7 CMN |
53 | ### API additions |
54 | ||
70b0f128 JG |
55 | * The `git_merge_options` gained a `file_flags` member. |
56 | ||
eac773d9 CMN |
57 | * Parsing and retrieving a configuration value as a path is exposed |
58 | via `git_config_parse_path()` and `git_config_get_path()` | |
59 | respectively. | |
60 | ||
659cf202 CMN |
61 | * `git_repository_set_ident()` and `git_repository_ident()` serve to |
62 | set and query which identity will be used when writing to the | |
63 | reflog. | |
64 | ||
9a97f49e CMN |
65 | * `git_config_entry_free()` frees a config entry. |
66 | ||
67 | * `git_config_get_string_buf()` provides a way to safely retrieve a | |
68 | string from a non-snapshot configuration. | |
69 | ||
8acf058f CMN |
70 | * `git_annotated_commit_from_revspec()` allows to get an annotated |
71 | commit from an extended sha synatx string. | |
72 | ||
73 | * `git_repository_set_head_detached_from_annotated()`, | |
74 | `git_branch_create_from_annotated()` and | |
75 | `git_reset_from_annotated()` allow for the caller to provide an | |
76 | annotated commit through which they can control what expression is | |
77 | put into the reflog as the source/target. | |
d578b45f | 78 | |
a275fbc0 | 79 | * `git_index_add_frombuffer()` can now create a blob from memory |
b1ae3e53 CMN |
80 | buffer and add it to the index which is attached to a repository. |
81 | ||
82 | * The structure `git_fetch_options` has been added to determine the | |
83 | runtime configuration for fetching, such as callbacks, pruning and | |
84 | autotag behaviour. It has the runtime initializer | |
85 | `git_fetch_init_options()`. | |
86 | ||
87 | * The enum `git_fetch_prune_t` has been added, letting you specify the | |
88 | pruning behaviour for a fetch. | |
a275fbc0 | 89 | |
15fdf054 ET |
90 | * `git_stash_apply()` can now apply a stashed state from the stash list, |
91 | placing the data into the working directory and index. | |
92 | ||
93 | * `git_stash_pop()` will apply a stashed state (like `git_stash_apply()`) | |
94 | but will remove the stashed state after a successful application. | |
95 | ||
1396c381 CMN |
96 | * A new error code `GIT_EEOF` indicates an early EOF from the |
97 | server. This typically indicates an error with the URL or | |
98 | configuration of the server, and tools can use this to show messages | |
99 | about failing to communicate with the server. | |
100 | ||
16bcf0c7 CMN |
101 | ### API removals |
102 | ||
9663d1bd | 103 | * `git_remote_save()` and `git_remote_clear_refspecs()` have been |
b1ae3e53 CMN |
104 | removed. Remote's configuration is changed via the configuration |
105 | directly or through a convenience function which performs changes to | |
106 | the configuration directly. | |
107 | ||
108 | * `git_remote_set_callbacks()`, `git_remote_get_callbacks()` and | |
9663d1bd | 109 | `git_remote_set_transport()` have been removed and the remote no |
b1ae3e53 CMN |
110 | longer stores this configuration. |
111 | ||
70f7484d CMN |
112 | * `git_remote_set_fetch_refpecs()` and |
113 | `git_remote_set_push_refspecs()` have been removed. There is no | |
114 | longer a way to set the base refspecs at run-time. | |
115 | ||
16bcf0c7 CMN |
116 | ### Breaking API changes |
117 | ||
bf2ba529 JM |
118 | * `git_smart_subtransport_cb` now has a `param` parameter. |
119 | ||
70b0f128 JG |
120 | * The `git_merge_options` structure member `flags` has been renamed |
121 | to `tree_flags`. | |
122 | ||
b8c50808 | 123 | * The `git_merge_file_options` structure member `flags` is now |
70b0f128 JG |
124 | an unsigned int. It was previously a `git_merge_file_flags_t`. |
125 | ||
96b82b11 ET |
126 | * `GIT_CHECKOUT_SAFE_CREATE` has been removed. Most users will generally |
127 | be able to switch to `GIT_CHECKOUT_SAFE`, but if you require missing | |
128 | file handling during checkout, you may now use `GIT_CHECKOUT_SAFE | | |
129 | GIT_CHECKOUT_RECREATE_MISSING`. | |
130 | ||
41513659 CMN |
131 | * The `git_clone_options` and `git_submodule_update_options` |
132 | structures no longer have a `signature` field. | |
133 | ||
134 | * The following functions have removed the signature and/or log message | |
135 | parameters in favour of git-emulating ones. | |
136 | ||
137 | * `git_branch_create()`, `git_branch_move()` | |
138 | * `git_rebase_init()`, `git_rebase_abort()` | |
139 | * `git_reference_symbolic_create_matching()`, | |
140 | `git_reference_symbolic_create()`, `git_reference_create()`, | |
141 | `git_reference_create_matching()`, | |
142 | `git_reference_symbolic_set_target()`, | |
143 | `git_reference_set_target()`, `git_reference_rename()` | |
144 | * `git_remote_update_tips()`, `git_remote_fetch()`, `git_remote_push()` | |
145 | * `git_repository_set_head()`, | |
146 | `git_repository_set_head_detached()`, | |
147 | `git_repository_detach_head()` | |
148 | * `git_reset()` | |
149 | ||
9a97f49e CMN |
150 | * `git_config_get_entry()` now gives back a ref-counted |
151 | `git_config_entry`. You must free it when you no longer need it. | |
152 | ||
153 | * `git_config_get_string()` will return an error if used on a | |
154 | non-snapshot configuration, as there can be no guarantee that the | |
155 | returned pointer is valid. | |
156 | ||
385449b1 CMN |
157 | * `git_note_default_ref()` now uses a `git_buf` to return the string, |
158 | as the string is otherwise not guaranteed to stay allocated. | |
159 | ||
30640aa9 ET |
160 | * `git_rebase_operation_current()` will return `GIT_REBASE_NO_OPERATION` |
161 | if it is called immediately after creating a rebase session but before | |
162 | you have applied the first patch. | |
163 | ||
f3a199dd ET |
164 | * `git_rebase_options` now contains an optional pointer to |
165 | `git_checkout_options` that will be used for functions that modify | |
166 | the working directory, namely `git_checkout_init`, `git_checkout_next` | |
167 | and `git_checkout_abort`. As a result, `git_rebase_open` now also | |
168 | takes a `git_rebase_options` and only the `git_rebase_init` and | |
169 | `git_rebase_open` functions take a `git_rebase_options`, where they | |
170 | will persist the options to subsequent `git_rebase` calls. | |
171 | ||
b1ae3e53 CMN |
172 | * The `git_clone_options` struct now has fetch options in a |
173 | `fetch_opts` field instead of remote callbacks in | |
174 | `remote_callbacks`. | |
175 | ||
176 | * The following functions now longer act on a remote instance but | |
177 | change the repository's configuration. Their signatures have changed | |
178 | accordingly: | |
179 | ||
180 | * `git_remote_set_url()`, `git_remote_seturl()` | |
181 | * `git_remote_add_fetch()`, `git_remote_add_push()` and | |
182 | * `git_remote_set_autotag()` | |
183 | ||
184 | * `git_remote_connect()` and `git_remote_prune()` now take a pointer | |
185 | to the callbacks. | |
186 | ||
9663d1bd | 187 | * `git_remote_fetch()` and `git_remote_download()` now take a pointer |
b1ae3e53 CMN |
188 | to fetch options which determine the runtime configuration. |
189 | ||
190 | * The `git_remote_autotag_option_t` values have been changed. It has | |
191 | gained a `_FALLBACK` default value to specify no override for the | |
192 | configured setting. | |
193 | ||
194 | * `git_remote_update_tips()` now takes a pointer to the callbacks as | |
195 | well as a boolean whether to write `FETCH_HEAD` and the autotag | |
196 | setting. | |
197 | ||
ae5b9362 CMN |
198 | * `git_remote_create_anonymous()` no longer takes a fetch refspec as |
199 | url-only remotes cannot have configured refspecs. | |
200 | ||
b1ae3e53 CMN |
201 | * The `git_submodule_update_options` struct now has fetch options in |
202 | the `fetch_opts` field instead of callbacks in the | |
203 | `remote_callbacks` field. | |
204 | ||
205 | * The `push` function in the `git_transport` interface now takes a | |
206 | pointer to the remote callbacks. | |
207 | ||
98270f56 CMN |
208 | * The `git_index_entry` struct's fields' types have been changed to |
209 | more accurately reflect what is in fact stored in the | |
210 | index. Specifically, time and file size are 32 bits intead of 64, as | |
211 | these values are truncated. | |
212 | ||
c8b64f70 | 213 | v0.22 |
d30447cb CMN |
214 | ------ |
215 | ||
b91f28be | 216 | ### Changes or improvements |
e1fc03c9 | 217 | |
b91f28be | 218 | * `git_signature_new()` now requires a non-empty email address. |
274c3fa6 | 219 | |
b91f28be | 220 | * Use CommonCrypto libraries for SHA-1 calculation on Mac OS X. |
d412165f | 221 | |
b91f28be CMN |
222 | * Disable SSL compression and SSLv2 and SSLv3 ciphers in favor of TLSv1 |
223 | in OpenSSL. | |
d412165f | 224 | |
b91f28be CMN |
225 | * The fetch behavior of remotes with autotag set to `GIT_REMOTE_DOWNLOAD_TAGS_ALL` |
226 | has been changed to match git 1.9.0 and later. In this mode, libgit2 now | |
227 | fetches all tags in addition to whatever else needs to be fetched. | |
c180c065 | 228 | |
b91f28be CMN |
229 | * `git_checkout()` now handles case-changing renames correctly on |
230 | case-insensitive filesystems; for example renaming "readme" to "README". | |
7449c82e | 231 | |
b91f28be CMN |
232 | * The search for libssh2 is now done via pkg-config instead of a |
233 | custom search of a few directories. | |
3753110a | 234 | |
b91f28be CMN |
235 | * Add support for core.protectHFS and core.protectNTFS. Add more |
236 | validation for filenames which we write such as references. | |
5192bcc5 | 237 | |
b91f28be CMN |
238 | * The local transport now generates textual progress output like |
239 | git-upload-pack does ("counting objects"). | |
c180c065 | 240 | |
b91f28be CMN |
241 | * `git_checkout_index()` can now check out an in-memory index that is not |
242 | necessarily the repository's index, so you may check out an index | |
243 | that was produced by git_merge and friends while retaining the cached | |
244 | information. | |
1697cd6f | 245 | |
b91f28be CMN |
246 | * Remove the default timeout for receiving / sending data over HTTP using |
247 | the WinHTTP transport layer. | |
d4256ed5 | 248 | |
b91f28be | 249 | * Add SPNEGO (Kerberos) authentication using GSSAPI on Unix systems. |
46c8f7f8 | 250 | |
b91f28be CMN |
251 | * Provide built-in objects for the empty blob (e69de29) and empty |
252 | tree (4b825dc) objects. | |
262eec23 | 253 | |
b91f28be CMN |
254 | * The index' tree cache is now filled upon read-tree and write-tree |
255 | and the cache is written to disk. | |
0862f617 | 256 | |
b91f28be | 257 | * LF -> CRLF filter refuses to handle mixed-EOL files |
1697cd6f | 258 | |
b91f28be | 259 | * LF -> CRLF filter now runs when * text = auto (with Git for Windows 1.9.4) |
1697cd6f | 260 | |
b91f28be CMN |
261 | * File unlocks are atomic again via rename. Read-only files on Windows are |
262 | made read-write if necessary. | |
d58a64e9 | 263 | |
b91f28be | 264 | * Share open packfiles across repositories to share descriptors and mmaps. |
6812afaf | 265 | |
b91f28be | 266 | * Use a map for the treebuilder, making insertion O(1) |
2cd3cb8e | 267 | |
b91f28be CMN |
268 | * The build system now accepts an option EMBED_SSH_PATH which when set |
269 | tells it to include a copy of libssh2 at the given location. This is | |
270 | enabled for MSVC. | |
9fef46de CMN |
271 | |
272 | * Add support for refspecs with the asterisk in the middle of a | |
273 | pattern. | |
7db0e6ee | 274 | |
c5837cad CMN |
275 | * Fetching now performs opportunistic updates. To achieve this, we |
276 | introduce a difference between active and passive refspecs, which | |
b91f28be | 277 | make `git_remote_download()` and `git_remote_fetch()` to take a list of |
c5837cad CMN |
278 | resfpecs to be the active list, similarly to how git fetch accepts a |
279 | list on the command-line. | |
280 | ||
b91f28be CMN |
281 | * The THREADSAFE option to build libgit2 with threading support has |
282 | been flipped to be on by default. | |
209425ce | 283 | |
b91f28be CMN |
284 | * The remote object has learnt to prune remote-tracking branches. If |
285 | the remote is configured to do so, this will happen via | |
286 | `git_remote_fetch()`. You can also call `git_remote_prune()` after | |
287 | connecting or fetching to perform the prune. | |
288 | ||
289 | ||
290 | ### API additions | |
d524b2d3 | 291 | |
b91f28be CMN |
292 | * Introduce `git_buf_text_is_binary()` and `git_buf_text_contains_nul()` for |
293 | consumers to perform binary detection on a git_buf. | |
294 | ||
295 | * `git_branch_upstream_remote()` has been introduced to provide the | |
296 | branch.<name>.remote configuration value. | |
297 | ||
298 | * Introduce `git_describe_commit()` and `git_describe_workdir()` to provide | |
299 | a description of the current commit (and working tree, respectively) | |
300 | based on the nearest tag or reference | |
301 | ||
302 | * Introduce `git_merge_bases()` and the `git_oidarray` type to expose all | |
7db0e6ee | 303 | merge bases between two commits. |
eca07bcd | 304 | |
b91f28be | 305 | * Introduce `git_merge_bases_many()` to expose all merge bases between |
eca07bcd | 306 | multiple commits. |
67917281 | 307 | |
67917281 | 308 | * Introduce rebase functionality (using the merge algorithm only). |
b91f28be CMN |
309 | Introduce `git_rebase_init()` to begin a new rebase session, |
310 | `git_rebase_open()` to open an in-progress rebase session, | |
311 | `git_rebase_commit()` to commit the current rebase operation, | |
312 | `git_rebase_next()` to apply the next rebase operation, | |
313 | `git_rebase_abort()` to abort an in-progress rebase and `git_rebase_finish()` | |
67917281 ET |
314 | to complete a rebase operation. |
315 | ||
b91f28be CMN |
316 | * Introduce `git_note_author()` and `git_note_committer()` to get the author |
317 | and committer information on a `git_note`, respectively. | |
79b0ae4e | 318 | |
b91f28be CMN |
319 | * A factory function for ssh has been added which allows to change the |
320 | path of the programs to execute for receive-pack and upload-pack on | |
321 | the server, `git_transport_ssh_with_paths()`. | |
21083a71 | 322 | |
b91f28be CMN |
323 | * The ssh transport supports asking the remote host for accepted |
324 | credential types as well as multiple challeges using a single | |
325 | connection. This requires to know which username you want to connect | |
326 | as, so this introduces the USERNAME credential type which the ssh | |
327 | transport will use to ask for the username. | |
d88766c4 | 328 | |
b91f28be CMN |
329 | * The `GIT_EPEEL` error code has been introduced when we cannot peel a tag |
330 | to the requested object type; if the given object otherwise cannot be | |
331 | peeled, `GIT_EINVALIDSPEC` is returned. | |
68182085 | 332 | |
b91f28be CMN |
333 | * Introduce `GIT_REPOSITORY_INIT_RELATIVE_GITLINK` to use relative paths |
334 | when writing gitlinks, as is used by git core for submodules. | |
e284c451 | 335 | |
b91f28be | 336 | * `git_remote_prune()` has been added. See above for description. |
799e22ea | 337 | |
8aba3d47 | 338 | |
b91f28be CMN |
339 | * Introduce reference transactions, which allow multiple references to |
340 | be locked at the same time and updates be queued. This also allows | |
341 | us to safely update a reflog with arbitrary contents, as we need to | |
342 | do for stash. | |
6d91dc53 | 343 | |
b91f28be | 344 | ### API removals |
dce7b1a4 | 345 | |
b91f28be CMN |
346 | * `git_remote_supported_url()` and `git_remote_is_valid_url()` have been |
347 | removed as they have become essentially useless with rsync-style ssh paths. | |
348 | ||
349 | * `git_clone_into()` and `git_clone_local_into()` have been removed from the | |
350 | public API in favour of `git_clone callbacks`. | |
351 | ||
352 | * The option to ignore certificate errors via `git_remote_cert_check()` | |
353 | is no longer present. Instead, `git_remote_callbacks` has gained a new | |
354 | entry which lets the user perform their own certificate checks. | |
355 | ||
356 | ### Breaking API changes | |
208a2c8a | 357 | |
b91f28be CMN |
358 | * `git_cherry_pick()` is now `git_cherrypick()`. |
359 | ||
360 | * The `git_submodule_update()` function was renamed to | |
361 | `git_submodule_update_strategy()`. `git_submodule_update()` is now used to | |
362 | provide functionalty similar to "git submodule update". | |
363 | ||
364 | * `git_treebuilder_create()` was renamed to `git_treebuilder_new()` to better | |
208a2c8a CMN |
365 | reflect it being a constructor rather than something which writes to |
366 | disk. | |
40d79154 | 367 | |
b91f28be CMN |
368 | * `git_treebuilder_new()` (was `git_treebuilder_create()`) now takes a |
369 | repository so that it can query repository configuration. | |
370 | Subsequently, `git_treebuilder_write()` no longer takes a repository. | |
aad27e6e | 371 | |
b91f28be CMN |
372 | * `git_threads_init()` and `git_threads_shutdown()` have been renamed to |
373 | `git_libgit2_init()` and `git_libgit2_shutdown()` to better explain what | |
374 | their purpose is, as it's grown to be more than just about threads. | |
aad27e6e | 375 | |
b91f28be CMN |
376 | * `git_libgit2_init()` and `git_libgit2_shutdown()` now return the number of |
377 | initializations of the library, so consumers may schedule work on the | |
378 | first initialization. | |

380 | * The `git_transport_register()` function no longer takes a priority and takes |
381 | a URL scheme name (eg "http") instead of a prefix like "http://" | |
aad27e6e | 382 | |

383 | * `git_index_name_entrycount()` and `git_index_reuc_entrycount()` now |
384 | return size_t instead of unsigned int. | |

386 | * The `context_lines` and `interhunk_lines` fields in `git_diff`_options are |
387 | now `uint32_t` instead of `uint16_t`. This allows to set them to `UINT_MAX`, | |
388 | in effect asking for "infinite" context e.g. to iterate over all the | |
389 | unmodified lines of a diff. | |
974d21c8 | 390 | |

391 | * `git_status_file()` now takes an exact path. Use `git_status_list_new()` if |
392 | pathspec searching is needed. | |
974d21c8 | 393 | |
b91f28be CMN |
394 | * `git_note_create()` has changed the position of the notes reference |
395 | name to match `git_note_remove()`. | |
974d21c8 | 396 | |
b91f28be CMN |
397 | * Rename `git_remote_load()` to `git_remote_lookup()` to bring it in line |
398 | with the rest of the lookup functions. | |
974d21c8 | 399 | |
b91f28be CMN |
400 | * `git_remote_rename()` now takes the repository and the remote's |
401 | current name. Accepting a remote indicates we want to change it, | |
402 | which we only did partially. It is much clearer if we accept a name | |
403 | and no loaded objects are changed. | |
974d21c8 | 404 | |
b91f28be CMN |
405 | * `git_remote_delete()` now accepts the repository and the remote's name |
406 | instead of a loaded remote. | |
974d21c8 | 407 | |
b91f28be CMN |
408 | * `git_merge_head` is now `git_annotated_commit`, to better reflect its usage |
409 | for multiple functions (including rebase) | |
974d21c8 | 410 | |
b91f28be CMN |
411 | * The `git_clone_options` struct no longer provides the `ignore_cert_errors` or |
412 | `remote_name` members for remote customization. | |
974d21c8 | 413 | |
b91f28be CMN |
414 | Instead, the `git_clone_options` struct has two new members, `remote_cb` and |
415 | `remote_cb_payload`, which allow the caller to completely override the remote | |
416 | creation process. If needed, the caller can use this callback to give their | |
417 | remote a name other than the default (origin) or disable cert checking. | |
974d21c8 | 418 | |
b91f28be CMN |
419 | The `remote_callbacks` member has been preserved for convenience, although it |
420 | is not used when a remote creation callback is supplied. | |
974d21c8 | 421 | |
b91f28be CMN |
422 | * The `git_clone`_options struct now provides `repository_cb` and |
423 | `repository_cb_payload` to allow the user to create a repository with | |
424 | custom options. | |
974d21c8 | 425 | |
b91f28be CMN |
426 | * The `git_push` struct to perform a push has been replaced with |
427 | `git_remote_upload()`. The refspecs and options are passed as a | |
428 | function argument. `git_push_update_tips()` is now also | |
429 | `git_remote_update_tips()` and the callbacks are in the same struct as | |
430 | the rest. | |
974d21c8 | 431 | |
b91f28be CMN |
432 | * The `git_remote_set_transport()` function now sets a transport factory function, |
433 | rather than a pre-existing transport instance. | |
61cd037e | 434 | |
b91f28be CMN |
435 | * The `git_transport` structure definition has moved into the sys/transport.h |
436 | file. | |
437 | ||
438 | * libgit2 no longer automatically sets the OpenSSL locking | |
439 | functions. This is not something which we can know to do. A | |
440 | last-resort convenience function is provided in sys/openssl.h, | |
441 | `git_openssl_set_locking()` which can be used to set the locking. |
