1Git v1.7.6 Release Notes 2======================== 3 4Updates since v1.7.5 5-------------------- 6 7 * Various git-svn updates. 8 9 * Updates the way content tags are handled in gitweb. Also adds 10 a UI to choose common timezone for displaying the dates. 11 12 * Similar to branch names, tagnames that begin with "-" are now 13 disallowed. 14 15 * Clean-up of the C part of i18n (but not l10n---please wait) 16 continues. 17 18 * The scripting part of the codebase is getting prepared for i18n/l10n. 19 20 * Pushing and pulling from a repository with large number of refs that 21 point to identical commits are optimized by not listing the same commit 22 during the common ancestor negotiation exchange with the other side. 23 24 * Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig) 25 using "git add" will send the contents straight to a packfile without 26 having to hold it and its compressed representation both at the same 27 time in memory. 28 29 * Processes spawned by "[alias] <name> = !process" in the configuration 30 can inspect GIT_PREFIX environment variable to learn where in the 31 working tree the original command was invoked. 32 33 * A magic pathspec ":/" tells a command that limits its operation to 34 the current directory when ran from a subdirectory to work on the 35 entire working tree. In general, ":/path/to/file" would be relative 36 to the root of the working tree hierarchy. 37 38 After "git reset --hard; edit Makefile; cd t/", "git add -u" would 39 be a no-op, but "git add -u :/" would add the updated contents of 40 the Makefile at the top level. If you want to name a path in the 41 current subdirectory whose unusual name begins with ":/", you can 42 name it by "./:/that/path" or by "\:/that/path". 43 44 * "git blame" learned "--abbrev[=<n>]" option to control the minimum 45 number of hexdigits shown for commit object names. 46 47 * "git blame" learned "--line-porcelain" that is less efficient but is 48 easier to parse. 49 50 * Aborting "git commit --interactive" discards updates to the index 51 made during the interactive session. 52 53 * "git commit" learned a "--patch" option to directly jump to the 54 per-hunk selection UI of the interactive mode. 55 56 * "git diff" and its family of commands learned --dirstat=0 to show 57 directories that contribute less than 0.1% of changes. 58 59 * "git diff" and its family of commands learned --dirstat=lines mode to 60 assess damage to the directory based on number of lines in the patch 61 output, not based on the similarity numbers. 62 63 * "git format-patch" learned "--quiet" option to suppress the output of 64 the names of generated files. 65 66 * "git format-patch" quotes people's names when it has RFC822 special 67 characters in it, e.g. "Junio C. Hamano" <jch@example.com>. Earlier 68 it was up to the user to do this when using its output. 69 70 * "git format-patch" can take an empty --subject-prefix now. 71 72 * "git grep" learned the "-P" option to take pcre regular expressions. 73 74 * "git log" and friends learned a new "--notes" option to replace the 75 "--show-notes" option. Unlike "--show-notes", "--notes=<ref>" does 76 not imply showing the default notes. 77 78 * They also learned a log.abbrevCommit configuration variable to augment 79 the --abbrev-commit command line option. 80 81 * "git ls-remote" learned "--exit-code" option to consider it a 82 different kind of error when no remote ref to be shown. 83 84 * "git merge" learned "-" as a short-hand for "the previous branch", just 85 like the way "git checkout -" works. 86 87 * "git merge" uses "merge.ff" configuration variable to decide to always 88 create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create 89 a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes 90 (or not setting it at all) restores the default behaviour of allowing 91 fast-forward to happen when possible. 92 93 * p4-import (from contrib) learned a new option --preserve-user. 94 95 * "git read-tree -m" learned "--dry-run" option that reports if a merge 96 would fail without touching the index nor the working tree. 97 98 * "git rebase" that does not specify on top of which branch to rebase 99 the current branch now uses @{upstream} of the current branch. 100 101 * "git rebase" finished either normally or with --abort did not 102 update the reflog for HEAD to record the event to come back to 103 where it started from. 104 105 * "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier 106 a fetch-mode mirror meant mirror everything, but now it only means refs are 107 not renamed. 108 109 * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked 110 commits separately, producing more a useful output. 111 112 * "git submodule update" learned "--force" option to get rid of local 113 changes in submodules and replace them with the up-to-date version. 114 115 * "git status" and friends ignore .gitmodules file while the file is 116 still in a conflicted state during a merge, to avoid using information 117 that is not final and possibly corrupt with conflict markers. 118 119Also contains various documentation updates and minor miscellaneous 120changes. 121 122 123Fixes since v1.7.5 124------------------ 125 126Unless otherwise noted, all the fixes in 1.7.5.X maintenance track are 127included in this release. 128 129 * "git config" used to choke with an insanely long line. 130 (merge ef/maint-strbuf-init later) 131 132 * "git diff --quiet" did not work well with --diff-filter. 133 (merge jk/diff-not-so-quick later) 134 135 * "git status -z" did not default to --porcelain output format. 136 (merge bc/maint-status-z-to-use-porcelain later)
