1Git 2.5 Release Notes 2===================== 3 4Updates since v2.4 5------------------ 6 7Ports 8 9 10UI, Workflows & Features 11 12 * "git p4" now detects the filetype (e.g. binary) correctly even when 13 the files are opened exclusively. 14 15 * git p4 attempts to better handle branches in Perforce. 16 17 * "git p4" learned "--changes-block-size <n>" to read the changes in 18 chunks from Perforce, instead of making one call to "p4 changes" 19 that may trigger "too many rows scanned" error from Perforce. 20 21 * "git show-branch --topics HEAD" (with no other arguments) did not 22 do anything interesting. Instead, contrast the given revision 23 against all the local branches by default. 24 25 * A replacement for contrib/workdir/git-new-workdir that does not 26 rely on symbolic links and make sharing of objects and refs safer 27 by making the borrowee and borrowers aware of each other. 28 29 * Tweak the sample "store" backend of the credential helper to honor 30 XDG configuration file locations when specified. 31 32 33Performance, Internal Implementation, Development Support etc. 34 35 * "unsigned char [20]" used thoughout the code to represent object 36 names are being converted into a semi-opaque "struct object_id". 37 This effort is expected to interfere with other topics in flight, 38 but hopefully will give us one extra level of abstraction in the 39 end, when completed. 40 41 * Catch a programmer mistake to feed a pointer not an array to 42 ARRAY_SIZE() macro, by using a couple of GCC extensions. 43 (merge 89c855e ep/do-not-feed-a-pointer-to-array-size later to maint). 44 45 * Some error messages in "git config" were emitted without calling 46 the usual error() facility. 47 48 * When "add--interactive" splits a hunk into two overlapping hunks 49 and then let the user choose only one, it sometimes feeds an 50 incorrect patch text to "git apply". Add tests to demonstrate 51 this. 52 53 I have a slight suspicion that this may be $gmane/87202 coming back 54 and biting us (I seem to have said "let's run with this and see 55 what happens" back then). 56 57 * More line-ending tests. 58 59 * An earlier rewrite to use strbuf_getwholeline() instead of fgets(3) 60 to read packed-refs file revealed that the former is unacceptably 61 inefficient. 62 63 * Many long-running operations show progress eye-candy, even when 64 they are later backgrounded. Hide the eye-candy when the process 65 is sent to the background instead. 66 (merge 9a9a41d lm/squelch-bg-progress later to maint). 67 68 69Also contains various documentation updates and code clean-ups. 70 71 72Fixes since v2.4 73---------------- 74 75Unless otherwise noted, all the fixes since v2.4 in the maintenance 76track are contained in this release (see the maintenance releases' 77notes for details). 78 79 * Memory usage of "git index-pack" has been trimmed by tens of 80 per-cent. 81 (merge c6458e6 nd/slim-index-pack-memory-usage later to maint). 82 83 * "git rev-list --objects $old --not --all" to see if everything that 84 is reachable from $old is already connected to the existing refs 85 was very inefficient. 86 (merge b6e8a3b jk/still-interesting later to maint). 87 88 * "hash-object --literally" introduced in v2.2 was not prepared to 89 take a really long object type name. 90 (merge 1427a7f jc/hash-object later to maint). 91 92 * "git rebase --quiet" was not quite quiet when there is nothing to 93 do. 94 (merge 22946a9 jk/rebase-quiet-noop later to maint). 95 96 * The completion for "log --decorate=" parameter value was incorrect. 97 (merge af16bda sg/complete-decorate-full-not-long later to maint). 98 99 * "filter-branch" corrupted commit log message that ends with an 100 incomplete line on platforms with some "sed" implementations that 101 munge such a line. Work it around by avoiding to use "sed". 102 (merge df06201 jk/filter-branch-use-of-sed-on-incomplete-line later to maint). 103 104 * "git daemon" fails to build from the source under NO_IPV6 105 configuration (regression in 2.4). 106 (merge d358f77 jc/daemon-no-ipv6-for-2.4.1 later to maint). 107 108 * Some time ago, "git blame" (incorrectly) lost the convert_to_git() 109 call when synthesizing a fake "tip" commit that represents the 110 state in the working tree, which broke folks who record the history 111 with LF line ending to make their project portabile across 112 platforms while terminating lines in their working tree files with 113 CRLF for their platform. 114 (merge 4bf256d tb/blame-resurrect-convert-to-git later to maint). 115 116 * We avoid setting core.worktree when the repository location is the 117 ".git" directory directly at the top level of the working tree, but 118 the code misdetected the case in which the working tree is at the 119 root level of the filesystem (which arguably is a silly thing to 120 do, but still valid). 121 (merge 84ccad8 jk/init-core-worktree-at-root later to maint). 122 123 * "git commit --date=now" or anything that relies on approxidate lost 124 the daylight-saving-time offset. 125 (merge f6e6362 jc/epochtime-wo-tz later to maint). 126 127 * Access to objects in repositories that borrow from another one on a 128 slow NFS server unnecessarily got more expensive due to recent code 129 becoming more cautious in a naive way not to lose objects to pruning. 130 (merge ee1c6c3 jk/prune-mtime later to maint). 131 132 * The codepaths that read .gitignore and .gitattributes files have been 133 taught that these files encoded in UTF-8 may have UTF-8 BOM marker at 134 the beginning; this makes it in line with what we do for configuration 135 files already. 136 (merge 27547e5 cn/bom-in-gitignore later to maint). 137 138 * a few helper scripts in the test suite did not report errors 139 correcty. 140 (merge de248e9 ep/fix-test-lib-functions-report later to maint). 141 142 * The default $HOME/.gitconfig file created upon "git config --global" 143 that edits it had incorrectly spelled user.name and user.email 144 entries in it. 145 (merge 7e11052 oh/fix-config-default-user-name-section later to maint). 146 147 * "git cat-file bl $blob" failed to barf even though there is no 148 object type that is "bl". 149 (merge b7994af jk/type-from-string-gently later to maint). 150 151 * The usual "git diff" when seeing a file turning into a directory 152 showed a patchset to remove the file and create all files in the 153 directory, but "git diff --no-index" simply refused to work. Also, 154 when asked to compare a file and a directory, imitate POSIX "diff" 155 and compare the file with the file with the same name in the 156 directory, instead of refusing to run. 157 (merge 0615173 jc/diff-no-index-d-f later to maint). 158 159 * Code cleanups and documentation updates. 160 (merge 0269f96 mm/usage-log-l-can-take-regex later to maint). 161 (merge 64f2589 nd/t1509-chroot-test later to maint). 162 (merge f86a374 sb/test-bitmap-free-at-end later to maint). 163 (merge 05bfc7d sb/line-log-plug-pairdiff-leak later to maint). 164 (merge 846e5df pt/xdg-config-path later to maint). 165 (merge 1154aa4 jc/plug-fmt-merge-msg-leak later to maint). 166 (merge 319b678 jk/sha1-file-reduce-useless-warnings later to maint).
