1 | Git ???? Release Notes |
2 | ====================== | |
3 | ||
4 | Updates since v2.3 | |
5 | ------------------ | |
6 | ||
7 | Ports | |
8 | ||
7f4ba4b6 JH |
9 | * Our default I/O size (8 MiB) for large files was too large for some |
10 | platforms with smaller SSIZE_MAX, leading to read(2)/write(2) | |
11 | failures. | |
12 | ||
13 | * We did not check the curl library version before using | |
14 | CURLOPT_PROXYAUTH feature that may not exist. | |
15 | ||
18d0fec2 JH |
16 | |
17 | UI, Workflows & Features | |
18 | ||
19 | * The command usage info strings given by "git cmd -h" and in | |
20 | documentation have been tweaked for consistency. | |
21 | ||
22 | * The "sync" subcommand of "git p4" now allows users to exclude | |
23 | subdirectories like its "clone" subcommand does. | |
24 | ||
25 | * "git log --invert-grep --grep=WIP" will show only commits that do | |
26 | not have the string "WIP" in their messages. | |
27 | ||
28 | * "git push" has been taught a "--atomic" option that makes push to | |
29 | update more than one ref an "all-or-none" affair. | |
30 | ||
31 | * Extending the "push to deploy" added in 2.3, the behaviour of "git | |
32 | push" when updating the branch that is checked out can now be | |
33 | tweaked by push-to-checkout hook. | |
34 | ||
f3f40774 JH |
35 | * Using environment variable LANGUAGE and friends on the client side, |
36 | HTTP-based transports now send Accept-Language when making requests. | |
37 | ||
7f4ba4b6 JH |
38 | * "git send-email" used to accept a mistaken "y" (or "yes") as an |
39 | answer to "What encoding do you want to use [UTF-8]? " without | |
40 | questioning. Now it asks for confirmation when the answer looks | |
41 | too short to be a valid encoding name. | |
42 | ||
97c12a8b JH |
43 | * When "git apply --whitespace=fix" fixed whitespace errors in the |
44 | common context lines, the command reports that it did so. | |
45 | ||
18d0fec2 JH |
46 | |
47 | Performance, Internal Implementation, Development Support etc. | |
48 | ||
49 | * Implementation of N_() macro has been updated slightly to help us | |
50 | detect mistakes. | |
51 | ||
52 | * Implementation of "reflog expire" has been restructured to fit the | |
53 | reflogs better with the recently updated ref API. | |
54 | ||
7f4ba4b6 JH |
55 | * The transport-helper did not give transport options such as |
56 | verbosity, progress, cloning, etc. to import and export based | |
57 | helpers, like it did for fetch and push based helpers, robbing them | |
58 | the chance to honor the wish of the end-users better. | |
59 | ||
60 | * The tests that wanted to see that file becomes unreadable after | |
61 | running "chmod a-r file", and the tests that wanted to make sure it | |
62 | is not run as root, we used "can we write into the / directory?" as | |
63 | a cheap substitute, but on some platforms that is not a good | |
64 | heuristics. The tests and their prerequisites have been updated to | |
65 | check what they really require. | |
66 | (merge f400e51 jk/sanity later to maint). | |
67 | ||
7a9409cb JH |
68 | * Various issues around "reflog expire", e.g. using --updateref when |
69 | expiring a reflog for a symbolic reference, have been corrected | |
70 | and/or made saner. | |
71 | ||
7f4ba4b6 JH |
72 | * The strbuf API was explained between the API documentation and in |
73 | the header file. Move missing bits to strbuf.h so that programmers | |
74 | can check only one place for all necessary information. | |
75 | ||
76 | * The error handling functions and conventions are now documented in | |
77 | the API manual. | |
78 | ||
79 | * Optimize attribute look-up, mostly useful in "git grep" on a | |
80 | project that does not use many attributes, by avoiding it when we | |
81 | (should) know that the attributes are not defined in the first | |
82 | place. | |
83 | ||
84 | * Typofix in comments. | |
85 | (merge ef2956a ak/git-pm-typofix later to maint). | |
86 | ||
87 | * Code clean-up. | |
88 | (merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint). | |
89 | (merge 5d30851 dp/remove-duplicated-header-inclusion later to maint). | |
90 | ||
5135fefa JH |
91 | * Simplify the ref transaction API around how "the ref should be |
92 | pointing at this object" is specified. | |
7f4ba4b6 | 93 | |
18d0fec2 JH |
94 | |
95 | Also contains various documentation updates and code clean-ups. | |
96 | ||
97 | ||
98 | Fixes since v2.3 | |
99 | ---------------- | |
100 | ||
101 | Unless otherwise noted, all the fixes since v2.3 in the maintenance | |
102 | track are contained in this release (see the maintenance releases' | |
103 | notes for details). | |
104 | ||
105 | * "git blame HEAD -- missing" failed to correctly say "HEAD" when it | |
106 | tried to say "No such path 'missing' in HEAD". | |
107 | (merge a46442f jk/blame-commit-label later to maint). | |
108 | ||
109 | * "git rerere" (invoked internally from many mergy operations) did | |
110 | not correctly signal errors when told to update the working tree | |
111 | files and failed to do so for whatever reason. | |
112 | (merge 89ea903 jn/rerere-fail-on-auto-update-failure later to maint). | |
113 | ||
114 | * Setting diff.submodule to 'log' made "git format-patch" produce | |
115 | broken patches. | |
116 | (merge 339de50 dk/format-patch-ignore-diff-submodule later to maint). | |
117 | ||
118 | * After attempting and failing a password-less authentication | |
119 | (e.g. kerberos), libcURL refuses to fall back to password based | |
120 | Basic authentication without a bit of help/encouragement. | |
121 | (merge 4dbe664 bc/http-fallback-to-password-after-krb-fails later to maint). | |
3188ab3a JH |
122 | |
123 | * The "git push" documentation made the "--repo=<there>" option | |
124 | easily misunderstood. | |
125 | (merge 57b92a7 mg/push-repo-option-doc later to maint). | |
126 | ||
127 | * Code to read branch name from various files in .git/ directory | |
128 | would have misbehaved if the code to write them left an empty file. | |
129 | (merge 66ec904 jk/status-read-branch-name-fix later to maint). | |
130 | ||
131 | * A misspelled conditional that is always true has been fixed. | |
132 | (merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint). | |
133 | ||
134 | * The documentation incorrectly said that C(opy) and R(ename) are the | |
135 | only ones that can be followed by the score number in the output in | |
136 | the --raw format. | |
137 | (merge ac1c2d9 jc/diff-format-doc later to maint). | |
138 | ||
139 | * A broken pack .idx file in the receiving repository prevented the | |
140 | dumb http transport from fetching a good copy of it from the other | |
141 | side. | |
142 | (merge 8b9c2dd jk/dumb-http-idx-fetch-fix later to maint). | |
143 | ||
144 | * The error message from "git commit", when a non-existing author | |
145 | name was given as value to the "--author=" parameter, has been | |
146 | reworded to avoid misunderstanding. | |
147 | (merge 1044b1f mg/commit-author-no-match-malformed-message later to maint). | |
148 | ||
149 | * "git log --help" used to show rev-list options that are irrelevant | |
150 | to the "log" command. | |
151 | (merge 3cab02d jc/doc-log-rev-list-options later to maint). | |
152 | ||
153 | * "git apply --whitespace=fix" used to under-allocate the memory when | |
154 | the fix resulted in a longer text than the original patch. | |
155 | (merge 407a792 jc/apply-ws-fix-expands later to maint). | |
156 | ||
157 | * The interactive "show a list and let the user choose from it" | |
158 | interface "add -i" used showed and prompted to the user even when | |
159 | the candidate list was empty, against which the only "choice" the | |
160 | user could have made was to choose nothing. | |
161 | (merge a9c4641 ak/add-i-empty-candidates later to maint). | |
162 | ||
163 | * The insn sheet "git rebase -i" creates did not fully honor | |
164 | core.abbrev settings. | |
165 | (merge edb72d5 ks/rebase-i-abbrev later to maint). | |
166 | ||
167 | * "git fetch" over a remote-helper that cannot respond to "list" | |
168 | command could not fetch from a symbolic reference e.g. HEAD. | |
169 | (merge 33cae54 mh/deref-symref-over-helper-transport later to maint). | |
f3f40774 JH |
170 | |
171 | * "git push --signed" gave an incorrectly worded error message when | |
172 | the other side did not support the capability. | |
173 | (merge 45917f0 jc/push-cert later to maint). | |
174 | ||
175 | * We didn't format an integer that wouldn't fit in "int" but in | |
176 | "uintmax_t" correctly. | |
177 | (merge d306f3d jk/decimal-width-for-uintmax later to maint). | |
178 | ||
179 | * Reading configuration from a blob object, when it ends with a lone | |
180 | CR, use to confuse the configuration parser. | |
181 | (merge 1d0655c jk/config-no-ungetc-eof later to maint). | |
182 | ||
183 | * The pack bitmap support did not build with older versions of GCC. | |
184 | (merge bd4e882 jk/pack-bitmap later to maint). | |
185 | ||
186 | * The documentation wasn't clear that "remote.<nick>.pushURL" and | |
187 | "remote.<nick>.URL" are there to name the same repository accessed | |
188 | via different transports, not two separate repositories. | |
189 | (merge 697f652 jc/remote-set-url-doc later to maint). | |
190 | ||
191 | * Older GnuPG implementations may not correctly import the keyring | |
192 | material we prepare for the tests to use. | |
193 | (merge 1f985d6 ch/new-gpg-drops-rfc-1991 later to maint). | |
194 | ||
195 | * The credential helper for Windows (in contrib/) used to mishandle | |
196 | a user name with an at-sign in it. | |
197 | (merge 13d261e av/wincred-with-at-in-username-fix later to maint). | |
355d4e17 JH |
198 | |
199 | * Longstanding configuration variable naming rules has been added to | |
200 | the documentation. | |
201 | (merge 35840a3 jc/conf-var-doc later to maint). | |
202 | ||
203 | * An earlier workaround to squelch unhelpful deprecation warnings | |
204 | from the complier on Mac OSX unnecessarily set minimum required | |
205 | version of the OS, which the user might want to raise (or lower) | |
206 | for other reasons. | |
207 | (merge 88c03eb es/squelch-openssl-warnings-on-macosx later to maint). | |
208 | ||
209 | * Certain older vintages of cURL give irregular output from | |
210 | "curl-config --vernum", which confused our build system. | |
211 | (merge 3af6792 tc/curl-vernum-output-broken-in-7.11 later to maint). | |
212 | ||
213 | * In v2.2.0, we broke "git prune" that runs in a repository that | |
214 | borrows from an alternate object store. | |
215 | (merge b0a4264 jk/prune-mtime later to maint). | |
216 | ||
217 | * "git submodule add" failed to squash "path/to/././submodule" to | |
218 | "path/to/submodule". | |
219 | (merge 8196e72 ps/submodule-sanitize-path-upon-add later to maint). | |
220 | ||
221 | * "git merge-file" did not work correctly in a subdirectory. | |
222 | (merge 204a8ff ab/merge-file-prefix later to maint). | |
223 | ||
224 | * "git blame" died, trying to free an uninitialized piece of memory. | |
225 | (merge e600592 es/blame-commit-info-fix later to maint). | |
7f4ba4b6 JH |
226 | |
227 | * "git fast-import" used to crash when it could not close and | |
228 | conclude the resulting packfile cleanly. | |
229 | (merge 5e915f3 jk/fast-import-die-nicely-fix later to maint). | |
230 | ||
231 | * "update-index --refresh" used to leak when an entry cannot be | |
232 | refreshed for whatever reason. | |
233 | (merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint). | |
97c12a8b JH |
234 | |
235 | * The "interpolated-path" option of "git daemon" inserted any string | |
236 | client declared on the "host=" capability request without checking. | |
237 | Sanitize and limit %H and %CH to a saner and a valid DNS name. | |
238 | (merge b485373 jk/daemon-interpolate later to maint). | |
239 | ||
240 | * "git daemon" looked up the hostname even when "%CH" and "%IP" | |
241 | interpolations are not requested, which was unnecessary. | |
242 | (merge dc8edc8 rs/daemon-interpolate later to maint). | |
243 | ||
244 | * Even though we officially haven't dropped Perl 5.8 support, the | |
245 | Getopt::Long package that came with it does not support "--no-" | |
246 | prefix to negate a boolean option; manually add support to help | |
247 | people with older Getopt::Long package. | |
248 | (merge f471494 km/send-email-getopt-long-workarounds later to maint). | |
249 | ||
250 | * "git apply" was not very careful about reading from, removing, | |
251 | updating and creating paths outside the working tree (under | |
252 | --index/--cached) or the current directory (when used as a | |
253 | replacement for GNU patch). | |
254 | (merge e0d201b jc/apply-beyond-symlink later to maint). | |
5135fefa JH |
255 | |
256 | * A breakage to git-svn around v2.2 era that triggers premature | |
257 | closing of FileHandle has been corrected. | |
258 | (merge e426311 ew/svn-maint-fixes later to maint). | |
259 | ||
260 | * We did not parse username followed by literal IPv6 address in SSH | |
261 | transport URLs, e.g. ssh://user@[2001:db8::1]:22/repo.git | |
262 | correctly. | |
263 | (merge 3f55cca tb/connect-ipv6-parse-fix later to maint). | |
264 | ||
265 | * The configuration variable 'mailinfo.scissors' was hard to | |
266 | discover in the documentation. | |
267 | (merge afb5de7 mm/am-c-doc later to maint). | |
268 | ||
d67f9d5e JH |
269 | * The interaction between "git submodule update" and the |
270 | submodule.*.update configuration was not clearly documented. | |
271 | (merge 5c31acf ms/submodule-update-config-doc later to maint). | |
272 | ||
273 | * "git diff --shortstat --dirstat=changes" showed a dirstat based on | |
274 | lines that was never asked by the end user in addition to the | |
275 | dirstat that the user asked for. | |
276 | (merge ab27389 mk/diff-shortstat-dirstat-fix later to maint). | |
277 | ||
278 | * "git remote add" mentioned "--tags" and "--no-tags" and was not | |
279 | clear that fetch from the remote in the future will use the default | |
280 | behaviour when neither is given to override it. | |
281 | (merge aaba0ab mg/doc-remote-tags-or-not later to maint). | |
282 | ||
283 | * Description given by "grep -h" for its --exclude-standard option | |
284 | was phrased poorly. | |
285 | (merge 77fdb8a nd/grep-exclude-standard-help-fix later to maint). | |
286 | ||
287 | * The borrowed code in kwset API did not follow our usual convention | |
288 | to use "unsigned char" to store values that range from 0-255. | |
289 | (merge 189c860 bw/kwset-use-unsigned later to maint). | |
290 | ||
7a9409cb JH |
291 | * A corrupt input to "git diff -M" used to cause it to segfault. |
292 | (merge 4d6be03 jk/diffcore-rename-duplicate later to maint). | |
293 | ||
d67f9d5e | 294 | * Code cleanups and documentaiton updates. |
5135fefa JH |
295 | (merge 2ce63e9 rs/simple-cleanups later to maint). |
296 | (merge 33baa69 rj/no-xopen-source-for-cygwin later to maint). | |
297 | (merge 817d03e jc/diff-test-updates later to maint). | |
d67f9d5e JH |
298 | (merge eb32c66 ak/t5516-typofix later to maint). |
299 | (merge bcd57cb mr/doc-clean-f-f later to maint). |
