   1 Git v1.7.7 Release Notes
   2 ========================
   3
   4 Updates since v1.7.6
   5 --------------------
   6
   7  * The scripting part of the codebase is getting prepared for i18n/l10n.
   8
   9  * Interix, Cygwin and Minix ports got updated.
  10
  11  * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
  12
  13  * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
  14    before reading from gitweb_config.perl or from /etc/gitweb.conf
  15    (this last one is read only when per-repository gitweb_config.perl
  16    does not exist).
  17
  18  * Various codepaths that invoked zlib deflate/inflate assumed that these
  19    functions can compress or uncompress more than 4GB data in one call on
  20    platforms with 64-bit long, which has been corrected.
  21
  22  * Git now recognizes loose objects written by other implementations that
  23    use a non-standard window size for zlib deflation (e.g. Agit running on
  24    Android with 4kb window). We used to reject anything that was not
  25    deflated with 32kb window.
  26
  27  * Interaction between the use of pager and coloring of the output has
  28    been improved, especially when a command that is not built-in was
  29    involved.
  30
  31  * "git am" learned to pass the "--exclude=<path>" option through to underlying
  32    "git apply".
  33
  34  * You can now feed many empty lines before feeding an mbox file to
  35    "git am".
  36
  37  * "git archive" can be told to pass the output to gzip compression and
  38    produce "archive.tar.gz".
  39
  40  * "git bisect" can be used in a bare repository (provided that the test
  41    you perform per each iteration does not need a working tree, of
  42    course).
  43
  44  * The length of abbreviated object names in "git branch -v" output
  45    now honors the core.abbrev configuration variable.
  46
  47  * "git check-attr" can take relative paths from the command line.
  48
  49  * "git check-attr" learned an "--all" option to list the attributes for a
  50    given path.
  51
  52  * "git checkout" (both the code to update the files upon checking out a
  53    different branch and the code to checkout a specific set of files) learned
  54    to stream the data from object store when possible, without having to
  55    read the entire contents of a file into memory first. An earlier round
  56    of this code that is not in any released version had a large leak but
  57    now it has been plugged.
  58
  59  * "git clone" can now take a "--config key=value" option to set the
  60    repository configuration options that affect the initial checkout.
  61
  62  * "git commit <paths>..." now lets you feed relative pathspecs that
  63    refer to outside your current subdirectory.
  64
  65  * "git diff --stat" learned a --stat-count option to limit the output of
  66    a diffstat report.
  67
  68  * "git diff" learned a "--histogram" option to use a different diff
  69    generation machinery stolen from jgit, which might give better
  70    performance.
  71
  72  * "git diff" had a weird worst case behaviour that can be triggered
  73    when comparing files with potentially many places that could match.
  74
  75  * "git fetch", "git push" and friends no longer show connection
  76    errors for addresses that couldn't be connected to when at least one
  77    address succeeds (this is arguably a regression but a deliberate
  78    one).
  79
  80  * "git grep" learned "--break" and "--heading" options, to let users mimic
  81    the output format of "ack".
  82
  83  * "git grep" learned a "-W" option that shows wider context using the same
  84    logic used by "git diff" to determine the hunk header.
  85
  86  * Invoking the low-level "git http-fetch" without "-a" option (which
  87    git itself never did--normal users should not have to worry about
  88    this) is now deprecated.
  89
  90  * The "--decorate" option to "git log" and its family learned to
  91    highlight grafted and replaced commits.
  92
  93  * "git rebase master topci" no longer spews usage hints after giving
  94    the "fatal: no such branch: topci" error message.
  95
  96  * The recursive merge strategy implementation got a fairly large
  97    fix for many corner cases that may rarely happen in real world
  98    projects (it has been verified that none of the 16000+ merges in
  99    the Linux kernel history back to v2.6.12 is affected with the
 100    corner case bugs this update fixes).
 101
 102  * "git stash" learned an "--include-untracked option".
 103
 104  * "git submodule update" used to stop at the first error updating a
 105    submodule; it now goes on to update other submodules that can be
 106    updated, and reports the ones with errors at the end.
 107
 108  * "git push" can be told with the "--recurse-submodules=check" option to
 109    refuse pushing of the supermodule, if any of its submodules'
 110    commits hasn't been pushed out to their remotes.
 111
 112  * "git upload-pack" and "git receive-pack" learned to pretend that only a
 113    subset of the refs exist in a repository. This may help a site to
 114    put many tiny repositories into one repository (this would not be
 115    useful for larger repositories as repacking would be problematic).
 116
 117  * "git verify-pack" has been rewritten to use the "index-pack" machinery
 118    that is more efficient in reading objects in packfiles.
 119
 120  * test scripts for gitweb tried to run even when CGI-related perl modules
 121    are not installed; they now exit early when the latter are unavailable.
 122
 123 Also contains various documentation updates and minor miscellaneous
 124 changes.

 126
 127 Fixes since v1.7.6
 128 ------------------
 129
 130 Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
 131 included in this release.
 132
 133  * "git branch -m" and "git checkout -b" incorrectly allowed the tip
 134    of the branch that is currently checked out updated.
