   4Updates since v1.7.11

   7UI, Workflows & Features
   8
   9 * Git can be told to normalize pathnames it read from readdir(3) and
  10   all arguments it got from the command line into precomposed UTF-8
  11   (assuming that they come as decomposed UTF-8), in order to work
  12   around issues on Mac OS.
  13
  14   I think there still are other places that need conversion
  15   (e.g. paths that are read from stdin for some commands), but this
  16   should be a good first step in the right direction.
  17
  18 * Per-user $HOME/.gitconfig file can optionally be stored in
  19   $HOME/.config/git/config instead, which is in line with XDG.
  20
  21 * The value of core.attributesfile and core.excludesfile default to
  22   $HOME/.config/attributes and $HOME/.config/ignore respectively when
  23   these files exist.
  24
  25 * Scripted Porcelain writers now have access to the credential API via
  26   the "git credential" plumbing command.
  27
  28 * "git help" used to always default to "man" format even on platforms
  29   where "man" viewer is not widely available.
  30
  31 * "git clone --local $path" started its life as an experiment to
  32   optionally use link/copy when cloning a repository on the disk, but
  33   we didn't deprecate it after we made the option a no-op to always
  34   use the optimization.  The command learned "--no-local" option to
  35   turn this off, as a more explicit alternative over use of file://
  36   URL.
  37
  38 * "git fetch" and friends used to say "remote side hung up
  39   unexpectedly" when they failed to get response they expect from the
  40   other side, but one common reason why they don't get expected
  41   response is that the remote repository does not exist or cannot be
  42   read. The error message in this case was updated to give better
  43   hints to the user.
  44
  45 * git native protocol agents learned to show software version over
  46   the wire, so that the server log can be examined to see the vintage
  47   distribution of clients.
  48
  49 * "git help -w $cmd" can show HTML version of documentation for
  50   "git-$cmd" by setting help.htmlpath to somewhere other than the
  51   default location where the build procedure installs them locally;
  52   the variable can even point at a http:// URL.
  53
  54 * "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after
  55   each commit in the resulting history.
  56
  57 * "git status" gives finer classification to various states of paths
  58   in conflicted state and offer advice messages in its output.
  59
  60 * "git submodule" learned to deal with nested submodule structure
  61   where a module is contained within a module whose origin is
  62   specified as a relative URL to its superproject's origin.
  63
  64 * A rather heavy-ish "git completion" script has been split to create
  65   a separate "git prompting" script, to help lazy-autoloading of the
  66   completion part while making prompting part always available.
  67
  68
  69Foreign Interface
  70
  71 * "mediawiki" remote helper (in contrib/) learned to handle file
  72   attachments.
  73
  74 * vcs-svn has been updated to clean-up compilation, lift 32-bit
  75   limitations, etc.
  76
  77
  78Performance, Internal Implementation, etc. (please report possible regressions)
  79
  80 * Some tests showed false failures caused by a bug in ecryptofs.
  81
  82 * We no longer use AsciiDoc7 syntax in our documentation and favor a
  83   more modern style.
  84
  85 * "git am --rebasing" codepath was taught to grab authorship, log
  86   message and the patch text directly out of existing commits.  This
  87   will help rebasing commits that have confusing "diff" output in
  88   their log messages.
  89
  90 * "git index-pack" and "git pack-objects" use streaming API to read
  91   from the object store to avoid having to hold a large blob object
  92   in-core while they are doing their thing.
  93
  94 * Code to match paths with exclude patterns learned to avoid calling
  95   fnmatch() by comparing fixed leading substring literally when
  96   possible.
  97
  98
  99Also contains minor documentation updates and code clean-ups.

 102Fixes since v1.7.11
 103-------------------
 104
 105Unless otherwise noted, all the fixes since v1.7.11 in the maintenance
 106releases are contained in this release (see release notes to them for
 107details).
 108
 109 * "git show"'s auto-walking behaviour was an unreliable and
 110   unpredictable hack; it now behaves just like "git log" does when it
 111   walks.
 112   (merge c5941f1 tr/maint-show-walk later to maint).
 113
 114 * "git diff", "git status" and anything that internally uses the
 115   comparison machinery was utterly broken when the difference
 116   involved a file with "-" as its name.  This was due to the way "git
 117   diff --no-index" was incorrectly bolted on to the system, making
 118   any comparison that involves a file "-" at the root level
 119   incorrectly read from the standard input.
 120   (merge 4682d85 jc/refactor-diff-stdin later to maint).
 121
 122 * We did not have test to make sure "git rebase" without extra options
 123   filters out an empty commit in the original history.
 124   (merge 2b5ba7b mz/empty-rebase-test later to maint).
 125
 126 * "git fast-export" produced an input stream for fast-import without
 127   properly quoting pathnames when they contain SPs in them.
 128   (merge ff59f6d js/fast-export-paths-with-spaces later to maint).
 129
 130 * "git checkout --detach", when you are still on an unborn branch,
 131   should be forbidden, but it wasn't.
 132   (merge 8ced1aa cw/no-detaching-an-unborn later to maint).
 133
 134 * Some implementations of Perl terminates "lines" with CRLF even when
 135   the script is operating on just a sequence of bytes.  Make sure to
 136   use "$PERL_PATH", the version of Perl the user told Git to use, in
 137   our tests to avoid unnecessary breakages in tests.
 138   (merge ad78585 vr/use-our-perl-in-tests later to maint).
