1Git ???? Release Notes 2====================== 3 4Updates since v2.3 5------------------ 6 7Ports 8 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 16 17UI, 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 35 * Using environment variable LANGUAGE and friends on the client side, 36 HTTP-based transports now send Accept-Language when making requests. 37 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 43 44Performance, Internal Implementation, Development Support etc. 45 46 * Implementation of N_() macro has been updated slightly to help us 47 detect mistakes. 48 49 * Implementation of "reflog expire" has been restructured to fit the 50 reflogs better with the recently updated ref API. 51 52 * The transport-helper did not give transport options such as 53 verbosity, progress, cloning, etc. to import and export based 54 helpers, like it did for fetch and push based helpers, robbing them 55 the chance to honor the wish of the end-users better. 56 57 * The tests that wanted to see that file becomes unreadable after 58 running "chmod a-r file", and the tests that wanted to make sure it 59 is not run as root, we used "can we write into the / directory?" as 60 a cheap substitute, but on some platforms that is not a good 61 heuristics. The tests and their prerequisites have been updated to 62 check what they really require. 63 (merge f400e51 jk/sanity later to maint). 64 65 * The strbuf API was explained between the API documentation and in 66 the header file. Move missing bits to strbuf.h so that programmers 67 can check only one place for all necessary information. 68 69 * The error handling functions and conventions are now documented in 70 the API manual. 71 72 * Optimize attribute look-up, mostly useful in "git grep" on a 73 project that does not use many attributes, by avoiding it when we 74 (should) know that the attributes are not defined in the first 75 place. 76 77 * Typofix in comments. 78 (merge ef2956a ak/git-pm-typofix later to maint). 79 80 * Code clean-up. 81 (merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint). 82 (merge 5d30851 dp/remove-duplicated-header-inclusion later to maint). 83 84 85 86Also contains various documentation updates and code clean-ups. 87 88 89Fixes since v2.3 90---------------- 91 92Unless otherwise noted, all the fixes since v2.3 in the maintenance 93track are contained in this release (see the maintenance releases' 94notes for details). 95 96 * "git blame HEAD -- missing" failed to correctly say "HEAD" when it 97 tried to say "No such path 'missing' in HEAD". 98 (merge a46442f jk/blame-commit-label later to maint). 99 100 * "git rerere" (invoked internally from many mergy operations) did 101 not correctly signal errors when told to update the working tree 102 files and failed to do so for whatever reason. 103 (merge 89ea903 jn/rerere-fail-on-auto-update-failure later to maint). 104 105 * Setting diff.submodule to 'log' made "git format-patch" produce 106 broken patches. 107 (merge 339de50 dk/format-patch-ignore-diff-submodule later to maint). 108 109 * After attempting and failing a password-less authentication 110 (e.g. kerberos), libcURL refuses to fall back to password based 111 Basic authentication without a bit of help/encouragement. 112 (merge 4dbe664 bc/http-fallback-to-password-after-krb-fails later to maint). 113 114 * The "git push" documentation made the "--repo=<there>" option 115 easily misunderstood. 116 (merge 57b92a7 mg/push-repo-option-doc later to maint). 117 118 * Code to read branch name from various files in .git/ directory 119 would have misbehaved if the code to write them left an empty file. 120 (merge 66ec904 jk/status-read-branch-name-fix later to maint). 121 122 * A misspelled conditional that is always true has been fixed. 123 (merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint). 124 125 * The documentation incorrectly said that C(opy) and R(ename) are the 126 only ones that can be followed by the score number in the output in 127 the --raw format. 128 (merge ac1c2d9 jc/diff-format-doc later to maint). 129 130 * A broken pack .idx file in the receiving repository prevented the 131 dumb http transport from fetching a good copy of it from the other 132 side. 133 (merge 8b9c2dd jk/dumb-http-idx-fetch-fix later to maint). 134 135 * The error message from "git commit", when a non-existing author 136 name was given as value to the "--author=" parameter, has been 137 reworded to avoid misunderstanding. 138 (merge 1044b1f mg/commit-author-no-match-malformed-message later to maint). 139 140 * "git log --help" used to show rev-list options that are irrelevant 141 to the "log" command. 142 (merge 3cab02d jc/doc-log-rev-list-options later to maint). 143 144 * "git apply --whitespace=fix" used to under-allocate the memory when 145 the fix resulted in a longer text than the original patch. 146 (merge 407a792 jc/apply-ws-fix-expands later to maint). 147 148 * The interactive "show a list and let the user choose from it" 149 interface "add -i" used showed and prompted to the user even when 150 the candidate list was empty, against which the only "choice" the 151 user could have made was to choose nothing. 152 (merge a9c4641 ak/add-i-empty-candidates later to maint). 153 154 * The insn sheet "git rebase -i" creates did not fully honor 155 core.abbrev settings. 156 (merge edb72d5 ks/rebase-i-abbrev later to maint). 157 158 * "git fetch" over a remote-helper that cannot respond to "list" 159 command could not fetch from a symbolic reference e.g. HEAD. 160 (merge 33cae54 mh/deref-symref-over-helper-transport later to maint). 161 162 * "git push --signed" gave an incorrectly worded error message when 163 the other side did not support the capability. 164 (merge 45917f0 jc/push-cert later to maint). 165 166 * We didn't format an integer that wouldn't fit in "int" but in 167 "uintmax_t" correctly. 168 (merge d306f3d jk/decimal-width-for-uintmax later to maint). 169 170 * Reading configuration from a blob object, when it ends with a lone 171 CR, use to confuse the configuration parser. 172 (merge 1d0655c jk/config-no-ungetc-eof later to maint). 173 174 * The pack bitmap support did not build with older versions of GCC. 175 (merge bd4e882 jk/pack-bitmap later to maint). 176 177 * The documentation wasn't clear that "remote.<nick>.pushURL" and 178 "remote.<nick>.URL" are there to name the same repository accessed 179 via different transports, not two separate repositories. 180 (merge 697f652 jc/remote-set-url-doc later to maint). 181 182 * Older GnuPG implementations may not correctly import the keyring 183 material we prepare for the tests to use. 184 (merge 1f985d6 ch/new-gpg-drops-rfc-1991 later to maint). 185 186 * The credential helper for Windows (in contrib/) used to mishandle 187 a user name with an at-sign in it. 188 (merge 13d261e av/wincred-with-at-in-username-fix later to maint). 189 190 * Longstanding configuration variable naming rules has been added to 191 the documentation. 192 (merge 35840a3 jc/conf-var-doc later to maint). 193 194 * An earlier workaround to squelch unhelpful deprecation warnings 195 from the complier on Mac OSX unnecessarily set minimum required 196 version of the OS, which the user might want to raise (or lower) 197 for other reasons. 198 (merge 88c03eb es/squelch-openssl-warnings-on-macosx later to maint). 199 200 * Certain older vintages of cURL give irregular output from 201 "curl-config --vernum", which confused our build system. 202 (merge 3af6792 tc/curl-vernum-output-broken-in-7.11 later to maint). 203 204 * In v2.2.0, we broke "git prune" that runs in a repository that 205 borrows from an alternate object store. 206 (merge b0a4264 jk/prune-mtime later to maint). 207 208 * "git submodule add" failed to squash "path/to/././submodule" to 209 "path/to/submodule". 210 (merge 8196e72 ps/submodule-sanitize-path-upon-add later to maint). 211 212 * "git merge-file" did not work correctly in a subdirectory. 213 (merge 204a8ff ab/merge-file-prefix later to maint). 214 215 * "git blame" died, trying to free an uninitialized piece of memory. 216 (merge e600592 es/blame-commit-info-fix later to maint). 217 218 * "git fast-import" used to crash when it could not close and 219 conclude the resulting packfile cleanly. 220 (merge 5e915f3 jk/fast-import-die-nicely-fix later to maint). 221 222 * "update-index --refresh" used to leak when an entry cannot be 223 refreshed for whatever reason. 224 (merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint).
