Git v1.7.12 Release Notes (draft)

Updates since v1.7.11

UI, Workflows & Features

  • Git can be told to normalize pathnames it read from readdir(3) and
    all arguments it got from the command line into precomposed UTF-8
    (assuming that they come as decomposed UTF-8), in order to work
    around issues on Mac OS.

    I think there still are other places that need conversion
    (e.g. paths that are read from stdin for some commands), but this
    should be a good first step in the right direction.

  • Per-user $HOME/.gitconfig file can optionally be stored in
    $HOME/.config/git/config instead, which is in line with XDG.

  • The value of core.attributesfile and core.excludesfile default to
    $HOME/.config/git/attributes and $HOME/.config/git/ignore respectively
    when these files exist.

  • Logic to disambiguate abbreviated object names have been taught to
    take advantage of object types that are expected in the context,
    e.g. XXXXXX in the “git describe” output v1.2.3-gXXXXXX must be a
    commit object, not a blob nor a tree. This will help us prolong
    the lifetime of abbreviated object names.

  • “git apply” learned to wiggle the base version and perform three-way
    merge when a patch does not exactly apply to the version you have.

  • Scripted Porcelain writers now have access to the credential API via
    the “git credential” plumbing command.

  • “git help” used to always default to “man” format even on platforms
    where “man” viewer is not widely available.

  • “git clone –local $path” started its life as an experiment to
    optionally use link/copy when cloning a repository on the disk, but
    we didn’t deprecate it after we made the option a no-op to always
    use the optimization. The command learned “–no-local” option to
    turn this off, as a more explicit alternative over use of file://
    URL.

  • “git fetch” and friends used to say “remote side hung up
    unexpectedly” when they failed to get response they expect from the
    other side, but one common reason why they don’t get expected
    response is that the remote repository does not exist or cannot be
    read. The error message in this case was updated to give better
    hints to the user.

  • “git help -w $cmd” can show HTML version of documentation for
    “git-$cmd” by setting help.htmlpath to somewhere other than the
    default location where the build procedure installs them locally;
    the variable can even point at a http:// URL.

  • “git rebase [-i] –root $tip” can now be used to rewrite all the
    history leading to “$tip” down to the root commit.

  • “git rebase -i” learned “-x <cmd>” to insert “exec <cmd>” after
    each commit in the resulting history.

  • “git status” gives finer classification to various states of paths
    in conflicted state and offer advice messages in its output.

  • “git submodule” learned to deal with nested submodule structure
    where a module is contained within a module whose origin is
    specified as a relative URL to its superproject’s origin.

  • A rather heavy-ish “git completion” script has been split to create
    a separate “git prompting” script, to help lazy-autoloading of the
    completion part while making prompting part always available.

  • “gitweb” pays attention to various forms of credits that are
    similar to “Signed-off-by:” lines in the commit objects and
    highlights them accordingly.

Foreign Interface

  • “mediawiki” remote helper (in contrib/) learned to handle file
    attachments.

  • “git p4” now uses “Jobs:” and “p4 move” when appropriate.

  • vcs-svn has been updated to clean-up compilation, lift 32-bit
    limitations, etc.

Performance, Internal Implementation, etc. (please report possible regressions)

  • Some tests showed false failures caused by a bug in ecryptofs.

  • We no longer use AsciiDoc7 syntax in our documentation and favor a
    more modern style.

  • “git am –rebasing” codepath was taught to grab authorship, log
    message and the patch text directly out of existing commits. This
    will help rebasing commits that have confusing “diff” output in
    their log messages.

  • “git index-pack” and “git pack-objects” use streaming API to read
    from the object store to avoid having to hold a large blob object
    in-core while they are doing their thing.

  • Code to match paths with exclude patterns learned to avoid calling
    fnmatch() by comparing fixed leading substring literally when
    possible.

  • “git log -n 1 — rarely-touched-path” was spending unnecessary
    cycles after showing the first change to find the next one, only to
    discard it.

  • “git svn” got a large-looking code reorganization at the last
    minute before the code freeze.

Also contains minor documentation updates and code clean-ups.

Fixes since v1.7.11

Unless otherwise noted, all the fixes since v1.7.11 in the maintenance
releases are contained in this release (see release notes to them for
details).

  • “git submodule add” was confused when the superproject did not have
    its repository in its usual place in the working tree and GIT_DIR
    and GIT_WORK_TREE was used to access it.

  • “git commit –amend” let the user edit the log message and then died
    when the human-readable committer name was given insufficiently by
    getpwent(3).
