1Git v2.9.3 Release Notes 2======================== 3 4Fixes since v2.9.2 5------------------ 6 7 * A helper function that takes the contents of a commit object and 8 finds its subject line did not ignore leading blank lines, as is 9 commonly done by other codepaths. Make it ignore leading blank 10 lines to match. 11 12 * Git does not know what the contents in the index should be for a 13 path added with "git add -N" yet, so "git grep --cached" should not 14 show hits (or show lack of hits, with -L) in such a path, but that 15 logic does not apply to "git grep", i.e. searching in the working 16 tree files. But we did so by mistake, which has been corrected. 17 18 * "git rebase -i --autostash" did not restore the auto-stashed change 19 when the operation was aborted. 20 21 * "git commit --amend --allow-empty-message -S" for a commit without 22 any message body could have misidentified where the header of the 23 commit object ends. 24 25 * More mark-up updates to typeset strings that are expected to 26 literally typed by the end user in fixed-width font. 27 28 * For a long time, we carried an in-code comment that said our 29 colored output would work only when we use fprintf/fputs on 30 Windows, which no longer is the case for the past few years. 31 32 * "gc.autoPackLimit" when set to 1 should not trigger a repacking 33 when there is only one pack, but the code counted poorly and did 34 so. 35 36 * One part of "git am" had an oddball helper function that called 37 stuff from outside "his" as opposed to calling what we have "ours", 38 which was not gender-neutral and also inconsistent with the rest of 39 the system where outside stuff is usuall called "theirs" in 40 contrast to "ours". 41 42 * The test framework learned a new helper test_match_signal to 43 check an exit code from getting killed by an expected signal. 44 45 * "git blame -M" missed a single line that was moved within the file. 46 47 * Fix recently introduced codepaths that are involved in parallel 48 submodule operations, which gave up on reading too early, and 49 could have wasted CPU while attempting to write under a corner 50 case condition. 51 52 * "git grep -i" has been taught to fold case in non-ascii locales 53 correctly. 54 55 * A test that unconditionally used "mktemp" learned that the command 56 is not necessarily available everywhere. 57 58 * "git blame file" allowed the lineage of lines in the uncommitted, 59 unadded contents of "file" to be inspected, but it refused when 60 "file" did not appear in the current commit. When "file" was 61 created by renaming an existing file (but the change has not been 62 committed), this restriction was unnecessarily tight. 63 64 * "git add -N dir/file && git write-tree" produced an incorrect tree 65 when there are other paths in the same directory that sorts after 66 "file". 67 68 * "git fetch http://user:pass@host/repo..." scrubbed the userinfo 69 part, but "git push" didn't. 70 71 * An age old bug that caused "git diff --ignore-space-at-eol" 72 misbehave has been fixed. 73 74 * "git notes merge" had a code to see if a path exists (and fails if 75 it does) and then open the path for writing (when it doesn't). 76 Replace it with open with O_EXCL. 77 78 * "git pack-objects" and "git index-pack" mostly operate with off_t 79 when talking about the offset of objects in a packfile, but there 80 were a handful of places that used "unsigned long" to hold that 81 value, leading to an unintended truncation. 82 83 * Recent update to "git daemon" tries to enable the socket-level 84 KEEPALIVE, but when it is spawned via inetd, the standard input 85 file descriptor may not necessarily be connected to a socket. 86 Suppress an ENOTSOCK error from setsockopt(). 87 88 * Recent FreeBSD stopped making perl available at /usr/bin/perl; 89 switch the default the built-in path to /usr/local/bin/perl on not 90 too ancient FreeBSD releases. 91 92 * "git status" learned to suggest "merge --abort" during a conflicted 93 merge, just like it already suggests "rebase --abort" during a 94 conflicted rebase. 95 96 * The .c/.h sources are marked as such in our .gitattributes file so 97 that "git diff -W" and friends would work better. 98 99 * Existing autoconf generated test for the need to link with pthread 100 library did not check all the functions from pthread libraries; 101 recent FreeBSD has some functions in libc but not others, and we 102 mistakenly thought linking with libc is enough when it is not. 103 104 * Allow http daemon tests in Travis CI tests. 105 106 * Users of the parse_options_concat() API function need to allocate 107 extra slots in advance and fill them with OPT_END() when they want 108 to decide the set of supported options dynamically, which makes the 109 code error-prone and hard to read. This has been corrected by tweaking 110 the API to allocate and return a new copy of "struct option" array. 111 112 * The use of strbuf in "git rm" to build filename to remove was a bit 113 suboptimal, which has been fixed. 114 115 * "git commit --help" said "--no-verify" is only about skipping the 116 pre-commit hook, and failed to say that it also skipped the 117 commit-msg hook. 118 119 * "git merge" in Git v2.9 was taught to forbid merging an unrelated 120 lines of history by default, but that is exactly the kind of thing 121 the "--rejoin" mode of "git subtree" (in contrib/) wants to do. 122 "git subtree" has been taught to use the "--allow-unrelated-histories" 123 option to override the default. 124 125 * The build procedure for "git persistent-https" helper (in contrib/) 126 has been updated so that it can be built with more recent versions 127 of Go. 128 129 * There is an optimization used in "git diff $treeA $treeB" to borrow 130 an already checked-out copy in the working tree when it is known to 131 be the same as the blob being compared, expecting that open/mmap of 132 such a file is faster than reading it from the object store, which 133 involves inflating and applying delta. This however kicked in even 134 when the checked-out copy needs to go through the convert-to-git 135 conversion (including the clean filter), which defeats the whole 136 point of the optimization. The optimization has been disabled when 137 the conversion is necessary. 138 139 * "git -c grep.patternType=extended log --basic-regexp" misbehaved 140 because the internal API to access the grep machinery was not 141 designed well. 142 143 * Windows port was failing some tests in t4130, due to the lack of 144 inum in the returned values by its lstat(2) emulation. 145 146 * The characters in the label shown for tags/refs for commits in 147 "gitweb" output are now properly escaped for proper HTML output. 148 149 * FreeBSD can lie when asked mtime of a directory, which made the 150 untracked cache code to fall back to a slow-path, which in turn 151 caused tests in t7063 to fail because it wanted to verify the 152 behaviour of the fast-path. 153 154 * Squelch compiler warnings for netmalloc (in compat/) library. 155 156 * The API documentation for hashmap was unclear if hashmap_entry 157 can be safely discarded without any other consideration. State 158 that it is safe to do so. 159 160 * Not-so-recent rewrite of "git am" that started making internal 161 calls into the commit machinery had an unintended regression, in 162 that no matter how many seconds it took to apply many patches, the 163 resulting committer timestamp for the resulting commits were all 164 the same. 165 166 * "git difftool <paths>..." started in a subdirectory failed to 167 interpret the paths relative to that directory, which has been 168 fixed. 169 170Also contains minor documentation updates and code clean-ups.
