1Git v1.7.10 Release Notes 2========================= 3 4Compatibility Notes 5------------------- 6 7 * From this release on, the "git merge" command in an interactive 8 session will start an editor when it automatically resolves the 9 merge for the user to explain the resulting commit, just like the 10 "git commit" command does when it wasn't given a commit message. 11 12 If you have a script that runs "git merge" and keeps its standard 13 input and output attached to the user's terminal, and if you do not 14 want the user to explain the resulting merge commits, you can 15 export GIT_MERGE_AUTOEDIT environment variable set to "no", like 16 this: 17 18 #!/bin/sh 19 GIT_MERGE_AUTOEDIT=no 20 export GIT_MERGE_AUTOEDIT 21 22 to disable this behaviour (if you want your users to explain their 23 merge commits, you do not have to do anything). Alternatively, you 24 can give the "--no-edit" option to individual invocations of the 25 "git merge" command if you know everybody who uses your script has 26 Git v1.7.8 or newer. 27 28 * The "--binary/-b" options to "git am" have been a no-op for quite a 29 while and were deprecated in mid 2008 (v1.6.0). When you give these 30 options to "git am", it will now warn and ask you not to use them. 31 32 33Updates since v1.7.9 34-------------------- 35 36UI, Workflows & Features 37 38 * Teams for localizing the messages from the Porcelain layer of 39 commands are starting to form, thanks to Jiang Xin who volunteered 40 to be the localization coordinator. An initial set of translated 41 messages for simplified chinese is available. 42 43 * The configuration mechanism learned an "include" facility; an 44 assignment to the include.path pseudo-variable causes the named 45 file to be included in-place when Git looks up configuration 46 variables. 47 48 * A content filter (clean/smudge) used to be just a way to make the 49 recorded contents "more useful", and allowed to fail; a filter can 50 now optionally be marked as "required". 51 52 * Options whose names begin with "--no-" (e.g. the "--no-verify" 53 option of the "git commit" command) can be negated by omitting 54 "no-" from its name, e.g. "git commit --verify". 55 56 * "git am" learned to pass "-b" option to underlying "git mailinfo", so 57 that a bracketed string other than "PATCH" at the beginning can be kept. 58 59 * "git clone" learned "--single-branch" option to limit cloning to a 60 single branch (surprise!); tags that do not point into the history 61 of the branch are not fetched. 62 63 * "git clone" learned to detach the HEAD in the resulting repository 64 when the user specifies a tag with "--branch" (e.g., "--branch=v1.0"). 65 Clone also learned to print the usual "detached HEAD" advice in such 66 a case, similar to "git checkout v1.0". 67 68 * When showing a patch while ignoring whitespace changes, the context 69 lines are taken from the postimage, in order to make it easier to 70 view the output. 71 72 * "git diff --stat" learned to adjust the width of the output on 73 wider terminals, and give more columns to pathnames as needed. 74 75 * "diff-highlight" filter (in contrib/) was updated to produce more 76 aesthetically pleasing output. 77 78 * "fsck" learned "--no-dangling" option to omit dangling object 79 information. 80 81 * "git log -G" and "git log -S" learned to pay attention to the "-i" 82 option. With "-i", "log -G" ignores the case when finding patch 83 hunks that introduce or remove a string that matches the given 84 pattern. Similarly with "-i", "log -S" ignores the case when 85 finding the commit the given block of text appears or disappears 86 from the file. 87 88 * "git merge" in an interactive session learned to spawn the editor 89 by default to let the user edit the auto-generated merge message, 90 to encourage people to explain their merges better. Legacy scripts 91 can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior. 92 Both "git merge" and "git pull" can be given --no-edit from the 93 command line to accept the auto-generated merge message. 94 95 * The advice message given when the user didn't give enough clue on 96 what to merge to "git pull" and "git merge" has been updated to 97 be more concise and easier to understand. 98 99 * "git push" learned the "--prune" option, similar to "git fetch". 100 101 * The whole directory that houses a top-level superproject managed by 102 "git submodule" can be moved to another place. 103 104 * "git symbolic-ref" learned the "--short" option to abbreviate the 105 refname it shows unambiguously. 106 107 * "git tag --list" can be given "--points-at <object>" to limit its 108 output to those that point at the given object. 109 110 * "gitweb" allows intermediate entries in the directory hierarchy 111 that leads to a project to be clicked, which in turn shows the 112 list of projects inside that directory. 113 114 * "gitweb" learned to read various pieces of information for the 115 repositories lazily, instead of reading everything that could be 116 needed (including the ones that are not necessary for a specific 117 task). 118 119 * Project search in "gitweb" shows the substring that matched in the 120 project name and description highlighted. 121 122 * A new script "diffall" is added to contrib/; it drives an 123 external tool to perform a directory diff of two Git revisions 124 in one go, unlike "difftool" that compares one file at a time. 125 126Foreign Interface 127 128 * Improved handling of views, labels and branches in "git-p4" (in contrib). 129 130 * "git-p4" (in contrib) suffered from unnecessary merge conflicts when 131 p4 expanded the embedded $RCS$-like keywords; it can be now told to 132 unexpand them. 133 134 * Some "git-svn" updates. 135 136 * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and 137 support incremental imports. 138 139 * "git difftool/mergetool" learned to drive DeltaWalker. 140 141Performance 142 143 * Unnecessary calls to parse_object() "git upload-pack" makes in 144 response to "git fetch", have been eliminated, to help performance 145 in repositories with excessive number of refs. 146 147Internal Implementation (please report possible regressions) 148 149 * Recursive call chains in "git index-pack" to deal with long delta 150 chains have been flattened, to reduce the stack footprint. 151 152 * Use of add_extra_ref() API is now gone, to make it possible to 153 cleanly restructure the overall refs API. 154 155 * The command line parser of "git pack-objects" now uses parse-options 156 API. 157 158 * The test suite supports the new "test_pause" helper function. 159 160 * Parallel to the test suite, there is a beginning of performance 161 benchmarking framework. 162 163 * t/Makefile is adjusted to prevent newer versions of GNU make from 164 running tests in seemingly random order. 165 166 * The code to check if a path points at a file beyond a symbolic link 167 has been restructured to be thread-safe. 168 169 * When pruning directories that has become empty during "git prune" 170 and "git prune-packed", call closedir() that iterates over a 171 directory before rmdir() it. 172 173Also contains minor documentation updates and code clean-ups. 174 175 176Fixes since v1.7.9 177------------------ 178 179Unless otherwise noted, all the fixes since v1.7.9 in the maintenance 180releases are contained in this release (see release notes to them for 181details). 182 183 * The "remaining" subcommand to "git rerere" was not documented. 184 (merge 3e7a1df ph/rerere-doc later to maint). 185 186 * "git tag -s" honored "gpg.program" configuration variable since 187 1.7.9, but "git tag -v" and "git verify-tag" didn't. 188 (merge a2c2506 az/verify-tag-use-gpg-config later to maint). 189 190 * When "git config" diagnoses an error in a configuration file and 191 shows the line number for the offending line, it miscounted if the 192 error was at the end of line. 193 (merge 4b34059 ms/maint-config-error-at-eol-linecount later to maint). 194 195 * "gitweb" used to drop warnings in the log file when "heads" view is 196 accessed in a repository whose HEAD does not point at a valid 197 branch. 198 199--- 200exec >/var/tmp/1 201O=v1.7.10-rc0-50-gd973dc0 202echo O=$(git describe) 203git log --first-parent --oneline ^maint $O.. 204echo 205git shortlog --no-merges ^maint $O..
