   1 Git v2.37 Release Notes
   2 =======================
   3
   4 UI, Workflows & Features
   5
   6  * "vimdiff[123]" mergetool drivers have been reimplemented with a
   7    more generic layout mechanism.
   8
   9  * "git -v" and "git -h" are now understood as "git --version" and
  10    "git --help".
  11
  12  * The temporary files fed to external diff command are now generated
  13    inside a new temporary directory under the same basename.
  14
  15  * "git log --since=X" will stop traversal upon seeing a commit that
  16    is older than X, but there may be commits behind it that is younger
  17    than X when the commit was created with a faulty clock.  A new
  18    option is added to keep digging without stopping, and instead
  19    filter out commits with timestamp older than X.
  20
  21  * "git -c branch.autosetupmerge=simple branch $A $B" will set the $B
  22    as $A's upstream only when $A and $B shares the same name, and "git
  23    -c push.default=simple" on branch $A would push to update the
  24    branch $A at the remote $B came from.  Also more places use the
  25    sole remote, if exists, before defaulting to 'origin'.
  26
  27  * A new doc has been added that lists tips for tools to work with
  28    Git's codebase.
  29
  30  * "git remote -v" now shows the list-objects-filter used during
  31    fetching from the remote, if available.
  32
  33
  34 Performance, Internal Implementation, Development Support etc.
  35
  36  * The performance of the "untracked cache" feature has been improved
  37    when "--untracked-files=<mode>" and "status.showUntrackedFiles"
  38    are combined.
  39
  40  * "git stash" works better with sparse index entries.
  41
  42  * "git show :<path>" learned to work better with the sparse-index
  43    feature.
  44
  45  * Introduce and apply coccinelle rule to discourage an explicit
  46    comparison between a pointer and NULL, and applies the clean-up to
  47    the maintenance track.

  50 Fixes since v2.36
  51 -----------------
  52
  53  * "git submodule update" without pathspec should silently skip an
  54    uninitialized submodule, but it started to become noisy by mistake.
  55    (merge 4f1ccef87c gc/submodule-update-part2 later to maint).
  56
  57  * "diff-tree --stdin" has been broken for about a year, but 2.36
  58    release broke it even worse by breaking running the command with
  59    <pathspec>, which in turn broke "gitk" and got noticed.  This has
  60    been corrected by aligning its behaviour to that of "log".
  61    (merge f8781bfda3 jc/diff-tree-stdin-fix later to maint).
  62
  63  * Regression fix for 2.36 where "git name-rev" started to sometimes
  64    reference strings after they are freed.
  65    (merge 45a14f578e rs/name-rev-fix-free-after-use later to maint).
  66
  67  * "git show <commit1> <commit2>... -- <pathspec>" lost the pathspec
  68    when showing the second and subsequent commits, which has been
  69    corrected.
  70    (merge 5cdb38458e jc/show-pathspec-fix later to maint).
  71
  72  * "git fast-export -- <pathspec>" lost the pathspec when showing the
  73    second and subsequent commits, which has been corrected.
  74    (merge d1c25272f5 rs/fast-export-pathspec-fix later to maint).
  75
  76  * "git format-patch <args> -- <pathspec>" lost the pathspec when
  77    showing the second and subsequent commits, which has been
  78    corrected.
  79    (merge 91f8f7e46f rs/format-patch-pathspec-fix later to maint).
  80
  81  * "git clone --origin X" leaked piece of memory that held value read
  82    from the clone.defaultRemoteName configuration variable, which has
  83    been plugged.
  84    (merge 6dfadc8981 jc/clone-remote-name-leak-fix later to maint).
  85
  86  * Get rid of a bogus and over-eager coccinelle rule.
  87    (merge 08bdd3a185 jc/cocci-xstrdup-or-null-fix later to maint).
  88
  89  * The path taken by "git multi-pack-index" command from the end user
  90    was compared with path internally prepared by the tool withut first
  91    normalizing, which lead to duplicated paths not being noticed,
  92    which has been corrected.
  93    (merge 11f9e8de3d ds/midx-normalize-pathname-before-comparison later to maint).
  94
  95  * Correct choices of C compilers used in various CI jobs.
  96    (merge 3506cae04f ab/cc-package-fixes later to maint).
  97
  98  * Various cleanups to "git p4".
  99    (merge 4ff0108d9e jh/p4-various-fixups later to maint).
 100
 101  * The progress meter of "git blame" was showing incorrect numbers
 102    when processing only parts of the file.
 103    (merge e5f5d7d42e ea/progress-partial-blame later to maint).
 104
 105  * "git rebase --keep-base <upstream> <branch-to-rebase>" computed the
 106    commit to rebase onto incorrectly, which has been corrected.
 107    (merge 9e5ebe9668 ah/rebase-keep-base-fix later to maint).
 108
 109  * Fix a leak of FILE * in an error codepath.
 110    (merge c0befa0c03 kt/commit-graph-plug-fp-leak-on-error later to maint).
 111
 112  * Avoid problems from interaction between malloc_check and address
 113    sanitizer.
 114    (merge 067109a5e7 pw/test-malloc-with-sanitize-address later to maint).
 115
 116  * The commit summary shown after making a commit is matched to what
 117    is given in "git status" not to use the break-rewrite heuristics.
 118    (merge 84792322ed rs/commit-summary-wo-break-rewrite later to maint).
 119
 120  * Update a few end-user facing messages around eol conversion.
 121    (merge c970d30c2c ah/convert-warning-message later to maint).
 122
 123  * Trace2 documentation updates.
 124    (merge a6c80c313c js/trace2-doc-fixes later to maint).
 125
 126  * Build procedure fixup.
 127    (merge 1fbfd96f50 mg/detect-compiler-in-c-locale later to maint).
 128
 129  * "git pull" without "--recurse-submodules=<arg>" made
 130    submodule.recurse take precedence over fetch.recurseSubmodules by
 131    mistake, which has been corrected.
 132    (merge 5819417365 gc/pull-recurse-submodules later to maint).
 133
 134  * "git bisect" was too silent before it is ready to start computing
 135    the actual bisection, which has been corrected.
 136    (merge f11046e6de cd/bisect-messages-from-pre-flight-states later to maint).
 137
 138  * macOS CI jobs have been occasionally flaky due to tentative version
 139    skew between perforce and the homebrew packager.  Instead of
 140    failing the whole CI job, just let it skip the p4 tests when this
 141    happens.
 142    (merge f15e00b463 cb/ci-make-p4-optional later to maint).
 143
 144  * A bit of test framework fixes with a few fixes to issues found by
 145    valgrind.
 146    (merge 7c898554d7 ab/valgrind-fixes later to maint).
 147
 148  * "git archive --add-file=<path>" picked up the raw permission bits
 149    from the path and propagated to zip output in some cases, without
 150    normalization, which has been corrected (tar output did not have
 151    this issue).
 152    (merge 6a61661967 jc/archive-add-file-normalize-mode later to maint).
 153
 154  * "make coverage-report" without first running "make coverage" did
 155    not produce any meaningful result, which has been corrected.
 156    (merge 96ddfecc5b ep/coverage-report-wants-test-to-have-run later to maint).
 157
 158  * The "--current" option of "git show-branch" should have been made
 159    incompatible with the "--reflog" mode, but this was not enforced,
 160    which has been corrected.
 161    (merge 41c64ae0e7 jc/show-branch-g-current later to maint).
 162
 163  * "git fetch" unnecessarily failed when an unexpected optional
 164    section appeared in the output, which has been corrected.
 165    (merge 7709acf7be jt/fetch-peek-optional-section later to maint).
 166
 167  * The way "git fetch" without "--update-head-ok" ensures that HEAD in
 168    no worktree points at any ref being updated was too wasteful, which
 169    has been optimized a bit.
 170    (merge f7400da800 os/fetch-check-not-current-branch later to maint).
 171
 172  * "git fetch --recurse-submodules" from multiple remotes (either from
 173    a remote group, or "--all") used to make one extra "git fetch" in
 174    the submodules, which has been corrected.
 175    (merge 0353c68818 jc/avoid-redundant-submodule-fetch later to maint).
 176
 177  * With a recent update to refuse access to repositories of other
 178    people by default, "sudo make install" and "sudo git describe"
 179    stopped working.  This series intends to loosen it while keeping
 180    the safety.
 181    (merge b9063afda1 cb/path-owner-check-with-sudo later to maint).
 182
 183  * Other code cleanup, docfix, build fix, etc.
 184    (merge e6b2582da3 cm/reftable-0-length-memset later to maint).
