    1 Git v2.11.1 Release Notes
    2 =========================
    3 
    4 Fixes since v2.11
    5 -----------------
    6 
    7  * The default Travis-CI configuration specifies newer P4 and GitLFS.
    8 
    9  * The character width table has been updated to match Unicode 9.0
   10 
   11  * Update the isatty() emulation for Windows by updating the previous
   12    hack that depended on internals of (older) MSVC runtime.
   13 
   14  * "git rev-parse --symbolic" failed with a more recent notation like
   15    "HEAD^-1" and "HEAD^!".
   16 
   17  * An empty directory in a working tree that can simply be nuked used
   18    to interfere while merging or cherry-picking a change to create a
   19    submodule directory there, which has been fixed..
   20 
   21  * The code in "git push" to compute if any commit being pushed in the
   22    superproject binds a commit in a submodule that hasn't been pushed
   23    out was overly inefficient, making it unusable even for a small
   24    project that does not have any submodule but have a reasonable
   25    number of refs.
   26 
   27  * "git push --dry-run --recurse-submodule=on-demand" wasn't
   28    "--dry-run" in the submodules.
   29 
   30  * The output from "git worktree list" was made in readdir() order,
   31    and was unstable.
   32 
   33  * mergetool.<tool>.trustExitCode configuration variable did not apply
   34    to built-in tools, but now it does.
   35 
   36  * "git p4" LFS support was broken when LFS stores an empty blob.
   37 
   38  * Fix a corner case in merge-recursive regression that crept in
   39    during 2.10 development cycle.
   40 
   41  * Update the error messages from the dumb-http client when it fails
   42    to obtain loose objects; we used to give sensible error message
   43    only upon 404 but we now forbid unexpected redirects that needs to
   44    be reported with something sensible.
   45 
   46  * When diff.renames configuration is on (and with Git 2.9 and later,
   47    it is enabled by default, which made it worse), "git stash"
   48    misbehaved if a file is removed and another file with a very
   49    similar content is added.
   50 
   51  * "git diff --no-index" did not take "--no-abbrev" option.
   52 
   53  * "git difftool --dir-diff" had a minor regression when started from
   54    a subdirectory, which has been fixed.
   55 
   56  * "git commit --allow-empty --only" (no pathspec) with dirty index
   57    ought to be an acceptable way to create a new commit that does not
   58    change any paths, but it was forbidden, perhaps because nobody
   59    needed it so far.
   60 
   61  * A pathname that begins with "//" or "\\" on Windows is special but
   62    path normalization logic was unaware of it.
   63 
   64  * "git pull --rebase", when there is no new commits on our side since
   65    we forked from the upstream, should be able to fast-forward without
   66    invoking "git rebase", but it didn't.
   67 
   68  * The way to specify hotkeys to "xxdiff" that is used by "git
   69    mergetool" has been modernized to match recent versions of xxdiff.
   70 
   71  * Unlike "git am --abort", "git cherry-pick --abort" moved HEAD back
   72    to where cherry-pick started while picking multiple changes, when
   73    the cherry-pick stopped to ask for help from the user, and the user
   74    did "git reset --hard" to a different commit in order to re-attempt
   75    the operation.
   76 
   77  * Code cleanup in shallow boundary computation.
   78 
   79  * A recent update to receive-pack to make it easier to drop garbage
   80    objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot
   81    have a pathname with a colon in it (no surprise!), and this in turn
   82    made it impossible to push into a repository at such a path.  This
   83    has been fixed by introducing a quoting mechanism used when
   84    appending such a path to the colon-separated list.
   85 
   86  * The function usage_msg_opt() has been updated to say "fatal:"
   87    before the custom message programs give, when they want to die
   88    with a message about wrong command line options followed by the
   89    standard usage string.
   90 
   91  * "git index-pack --stdin" needs an access to an existing repository,
   92    but "git index-pack file.pack" to generate an .idx file that
   93    corresponds to a packfile does not.
   94 
   95  * Fix for NDEBUG builds.
   96 
   97  * A lazy "git push" without refspec did not internally use a fully
   98    specified refspec to perform 'current', 'simple', or 'upstream'
   99    push, causing unnecessary "ambiguous ref" errors.
  100 
  101  * "git p4" misbehaved when swapping a directory and a symbolic link.
  102 
  103  * Even though an fix was attempted in Git 2.9.3 days, but running
  104    "git difftool --dir-diff" from a subdirectory never worked. This
  105    has been fixed.
  106 
  107  * "git p4" that tracks multile p4 paths imported a single changelist
  108    that touches files in these multiple paths as one commit, followed
  109    by many empty commits.  This has been fixed.
  110 
  111  * A potential but unlikely buffer overflow in Windows port has been
  112    fixed.
  113 
  114  * When the http server gives an incomplete response to a smart-http
  115    rpc call, it could lead to client waiting for a full response that
  116    will never come.  Teach the client side to notice this condition
  117    and abort the transfer.
  118 
  119  * Some platforms no longer understand "latin-1" that is still seen in
  120    the wild in e-mail headers; replace them with "iso-8859-1" that is
  121    more widely known when conversion fails from/to it.
  122 
  123  * Update the procedure to generate "tags" for developer support.
  124 
  125  * Update the definition of the MacOSX test environment used by
  126    TravisCI.
  127 
  128  * A few git-svn updates.
  129 
  130  * Compression setting for producing packfiles were spread across
  131    three codepaths, one of which did not honor any configuration.
  132    Unify these so that all of them honor core.compression and
  133    pack.compression variables the same way.
  134 
  135  * "git fast-import" sometimes mishandled while rebalancing notes
  136    tree, which has been fixed.
  137 
  138  * Recent update to the default abbreviation length that auto-scales
  139    lacked documentation update, which has been corrected.
  140 
  141  * Leakage of lockfiles in the config subsystem has been fixed.
  142 
  143  * It is natural that "git gc --auto" may not attempt to pack
  144    everything into a single pack, and there is no point in warning
  145    when the user has configured the system to use the pack bitmap,
  146    leading to disabling further "gc".
  147 
  148  * "git archive" did not read the standard configuration files, and
  149    failed to notice a file that is marked as binary via the userdiff
  150    driver configuration.
  151 
  152  * "git blame --porcelain" misidentified the "previous" <commit, path>
  153    pair (aka "source") when contents came from two or more files.
  154 
  155  * "git rebase -i" with a recent update started showing an incorrect
  156    count when squashing more than 10 commits.
  157 
  158  * "git <cmd> @{push}" on a detached HEAD used to segfault; it has
  159    been corrected to error out with a message.
  160 
  161  * Tighten a test to avoid mistaking an extended ERE regexp engine as
  162    a PRE regexp engine.
  163 
  164  * Typing ^C to pager, which usually does not kill it, killed Git and
  165    took the pager down as a collateral damage in certain process-tree
  166    structure.  This has been fixed.
  167 
  168 Also contains various documentation updates and code clean-ups.
