1Git 2.8 Release Notes 2===================== 3 4Updates since v2.7 5------------------ 6 7UI, Workflows & Features 8 9 * "branch --delete" has "branch -d" but "push --delete" does not. 10 (merge 38a2559 ps/push-delete-option later to maint). 11 12 * "git blame" learned to produce the progress eye-candy when it takes 13 too much time before emitting the first line of the result. 14 15 * "git grep" can now be configured (or told from the command line) 16 how many threads to use when searching in the working tree files. 17 18 * Some "git notes" operations, e.g. "git log --notes=<note>", should 19 be able to read notes from any tree-ish that is shaped like a notes 20 tree, but the notes infrastructure required that the argument must 21 be a ref under refs/notes/. Loosen it to require a valid ref only 22 when the operation would update the notes (in which case we must 23 have a place to store the updated notes tree, iow, a ref). 24 25 * "git grep" by default does not fall back to its "--no-index" 26 behaviour outside a directory under Git's control (otherwise the 27 user may by mistake end up running a huge recursive search); with a 28 new configuration (set in $HOME/.gitconfig--by definition this 29 cannot be set in the config file per project), this safety can be 30 disabled. 31 32 33Performance, Internal Implementation, Development Support etc. 34 35 * Add a framework to spawn a group of processes in parallel, and use 36 it to run "git fetch --recurse-submodules" in parallel. 37 38 * A slight update to the Makefile to mark "phoney" targets 39 as such correctly. 40 41 * In-core storage of the reverse index for .pack files (which lets 42 you go from a pack offset to an object name) has been streamlined. 43 44 * d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like 45 $GIT_DIR, 2015-06-26) attempted to work around a glitch in alias 46 handling by overwriting GIT_WORK_TREE environment variable to 47 affect subprocesses when set_git_work_tree() gets called, which 48 resulted in a rather unpleasant regression to "clone" and "init". 49 Try to address the same issue by always restoring the environment 50 and respawning the real underlying command when handling alias. 51 52 53Also contains various documentation updates and code clean-ups. 54 55 56Fixes since v2.7 57---------------- 58 59Unless otherwise noted, all the fixes since v2.7 in the maintenance 60track are contained in this release (see the maintenance releases' 61notes for details). 62 63 * An earlier change in 2.5.x-era broke users' hooks and aliases by 64 exporting GIT_WORK_TREE to point at the root of the working tree, 65 interfering when they tried to use a different working tree without 66 setting GIT_WORK_TREE environment themselves. 67 (merge df1e6ea nd/stop-setenv-work-tree later to maint). 68 69 * The "exclude_list" structure has the usual "alloc, nr" pair of 70 fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot 71 to reset 'alloc' to 0 when it cleared 'nr' to discard the managed 72 array. 73 (merge 2653a8c nd/dir-exclude-cleanup later to maint). 74 75 * Paths that have been told the index about with "add -N" are not 76 quite yet in the index, but a few commands behaved as if they 77 already are in a harmful way. 78 (merge 4d55200 nd/ita-cleanup later to maint). 79 80 * "git send-email" was confused by escaped quotes stored in the alias 81 files saved by "mutt", which has been corrected. 82 (merge 2c510f2 ew/send-email-mutt-alias-fix later to maint). 83 84 * A few unportable C construct have been spotted by clang compiler 85 and have been fixed. 86 (merge a0df2e5 jk/clang-pedantic later to maint). 87 88 * The documentation has been updated to hint the connection between 89 the '--signoff' option and DCO. 90 (merge b2c150d dw/signoff-doc later to maint). 91 92 * "git reflog" incorrectly assumed that all objects that used to be 93 at the tip of a ref must be commits, which caused it to segfault. 94 (merge aecad37 dk/reflog-walk-with-non-commit later to maint). 95 96 * The ignore mechanism saw a few regressions around untracked file 97 listing and sparse checkout selection areas in 2.7.0; the change 98 that is responsible for the regression has been reverted. 99 (merge 8c72236 nd/exclusion-regression-fix later to maint). 100 101 * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR 102 (e.g. COMMIT_EDITMSG) that is meant to be left after the command is 103 done. This however did not work well if the repository is set to 104 be shared with core.sharedRepository and the umask of the previous 105 user is tighter. They have been made to work better by calling 106 unlink(2) and retrying after fopen(3) fails with EPERM. 107 (merge ea56518 js/fopen-harder later to maint). 108 109 * Asking gitweb for a nonexistent commit left a warning in the server 110 log. 111 112 Somebody may want to follow this up with an additional test, perhaps? 113 IIRC, we do test that no Perl warnings are given to the server log, 114 so this should have been caught if our test coverage were good. 115 (merge a9eb90a ho/gitweb-squelch-undef-warning later to maint). 116 117 * Other minor clean-ups and documentation updates 118 (merge 99487cf ss/user-manual later to maint). 119 (merge e914ef0 ew/for-each-ref-doc later to maint). 120 (merge 36fc7d8 sg/t6050-failing-editor-test-fix later to maint). 121 (merge 60253a6 ss/clone-depth-single-doc later to maint).
