1Git v2.7.1 Release Notes 2======================== 3 4Fixes since v2.7 5---------------- 6 7 * An earlier change in 2.5.x-era broke users' hooks and aliases by 8 exporting GIT_WORK_TREE to point at the root of the working tree, 9 interfering when they tried to use a different working tree without 10 setting GIT_WORK_TREE environment themselves. 11 12 * The "exclude_list" structure has the usual "alloc, nr" pair of 13 fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot 14 to reset 'alloc' to 0 when it cleared 'nr' to discard the managed 15 array. 16 17 * "git send-email" was confused by escaped quotes stored in the alias 18 files saved by "mutt", which has been corrected. 19 20 * A few unportable C construct have been spotted by clang compiler 21 and have been fixed. 22 23 * The documentation has been updated to hint the connection between 24 the '--signoff' option and DCO. 25 26 * "git reflog" incorrectly assumed that all objects that used to be 27 at the tip of a ref must be commits, which caused it to segfault. 28 29 * The ignore mechanism saw a few regressions around untracked file 30 listing and sparse checkout selection areas in 2.7.0; the change 31 that is responsible for the regression has been reverted. 32 33 * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR 34 (e.g. COMMIT_EDITMSG) that is meant to be left after the command is 35 done. This however did not work well if the repository is set to 36 be shared with core.sharedRepository and the umask of the previous 37 user is tighter. They have been made to work better by calling 38 unlink(2) and retrying after fopen(3) fails with EPERM. 39 40 * Asking gitweb for a nonexistent commit left a warning in the server 41 log. 42 43 * "git rebase", unlike all other callers of "gc --auto", did not 44 ignore the exit code from "gc --auto". 45 46 * Many codepaths that run "gc --auto" before exiting kept packfiles 47 mapped and left the file descriptors to them open, which was not 48 friendly to systems that cannot remove files that are open. They 49 now close the packs before doing so. 50 51 * A recent optimization to filter-branch in v2.7.0 introduced a 52 regression when --prune-empty filter is used, which has been 53 corrected. 54 55 * The description for SANITY prerequisite the test suite uses has 56 been clarified both in the comment and in the implementation. 57 58 * "git tag" started listing a tag "foo" as "tags/foo" when a branch 59 named "foo" exists in the same repository; remove this unnecessary 60 disambiguation, which is a regression introduced in v2.7.0. 61 62 * The way "git svn" uses auth parameter was broken by Subversion 63 1.9.0 and later. 64 65 * The "split" subcommand of "git subtree" (in contrib/) incorrectly 66 skipped merges when it shouldn't, which was corrected. 67 68 * A few options of "git diff" did not work well when the command was 69 run from a subdirectory. 70 71 * dirname() emulation has been added, as Msys2 lacks it. 72 73 * The underlying machinery used by "ls-files -o" and other commands 74 have been taught not to create empty submodule ref cache for a 75 directory that is not a submodule. This removes a ton of wasted 76 CPU cycles. 77 78 * Drop a few old "todo" items by deciding that the change one of them 79 suggests is not such a good idea, and doing the change the other 80 one suggested to do. 81 82 * Documentation for "git fetch --depth" has been updated for clarity. 83 84 * The command line completion learned a handful of additional options 85 and command specific syntax. 86 87Also includes a handful of documentation and test updates.
