   1Git v1.8.4 Release Notes
   2========================
   3
   4Updates since v1.8.3
   5--------------------
   6
   7Foreign interface
   8
   9 * Remote transport helper has been updated to report errors and
  10   maintain ref hierarchy used to keep track of its own state better.
  11
  12
  13UI, Workflows & Features
  14
  15 * "check-ignore" (new feature since 1.8.2) has been updated to work
  16   more like "check-attr" over bidi-pipes.
  17
  18 * "git describe" learned "--first-parent" option to limit its closest
  19   tagged commit search to the first-parent chain.
  20
  21 * "git merge foo" that might have meant "git merge origin/foo" is
  22   diagnosed with a more informative error message.
  23
  24 * "git log -L<line>,<range>:<filename>" has been added.  This may
  25   still have leaks and rough edges, though.
  26
  27 * We used the approxidate() parser for "--expire=<timestamp>" options
  28   of various commands, but it is better to treat --expire=all and
  29   --expire=now a bit more specially than using the current timestamp.
  30   "git gc" and "git reflog" have been updated with a new parsing
  31   function for expiry dates.
  32
  33 * Updates to completion (both bash and zsh) helpers.
  34
  35 * The behaviour of the "--chain-reply-to" option of "git send-email"
  36   have changed at 1.7.0, and we added a warning/advice message to
  37   help users adjust to the new behaviour back then, but we kept it
  38   around for too long.  The message has finally been removed.
  39
  40 * "git fetch origin master" unlike "git fetch origin" or "git fetch"
  41   did not update "refs/remotes/origin/master"; this was an early
  42   design decision to keep the update of remote tracking branches
  43   predictable, but in practice it turns out that people find it more
  44   convenient to opportunistically update them whenever we have a
  45   chance, and we have been updating them when we run "git push" which
  46   already breaks the original "predictability" anyway.
  47
  48 * The configuration variable core.checkstat was advertised in the
  49   documentation but the code expected core.statinfo instead.
  50   For now, we accept both core.checkstat and core.statinfo, but the
  51   latter will be removed in the longer term.
  52
  53
  54Performance, Internal Implementation, etc.
  55
  56 * The codepath to read from marks files in fast-import/export did not
  57   have to accept anything but 40-hex representation of the object
  58   name.  Further, fast-export did not need full in-core object
  59   representation to have parsed wen reading from them.  These
  60   codepaths have been optimized by taking advantage of these access
  61   patterns.
  62
  63 * Object lookup logic, when the object hashtable starts to become
  64   crowded, has been optimized.
  65
  66 * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
  67   inconsistently between the test framework and t/Makefile, and logic
  68   to summarize the results looked at a wrong place.
  69
  70 * Many warnings from sparse source checker in compat/ area has been
  71   squelched.
  72
  73 * The code to reading and updating packed-refs file has been updated,
  74   correcting corner case bugs.
  75
  76
  77Also contains various documentation updates and code clean-ups.

  80Fixes since v1.8.3
  81------------------
  82
  83Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
  84track are contained in this release (see release notes to them for
  85details).
  86
  87 * Handling of negative exclude pattern for directories "!dir" was
  88   broken in the update to v1.8.3.
  89   (merge c3c327d kb/status-ignored-optim-2 later to maint).
  90
  91 * zsh prompt script that borrowed from bash prompt script did not
  92   work due to slight differences in array variable notation between
  93   these two shells.
  94   (merge d0583da tg/maint-zsh-svn-remote-prompt later to maint).
  95
  96 * An entry for "file://" scheme in the enumeration of URL types Git
  97   can take in the HTML documentation was made into a clickable link
  98   by mistake.
  99   (merge 4c32e36 nd/urls-doc-no-file-hyperlink-fix later to maint).
 100
 101 * "git push --[no-]verify" was not documented.
 102   (merge 90d32d1 tr/push-no-verify-doc later to maint).
 103
 104 * Stop installing the git-remote-testpy script that is only used for
 105   testing.
 106   (merge 416fda6 fc/makefile later to maint).
 107
 108 * "git commit --allow-empty-message -m ''" should not start an
 109   editor.
 110   (merge 2520677 rs/commit-m-no-edit later to maint).
 111
 112 * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
 113   incorrectly when your previous branch was "frotz" (it should be
 114   rewritten to "git merge frotz~22" instead).
 115   (merge 84cf246 jc/strbuf-branchname-fix later to maint).
 116
 117 * "git diff -c -p" was not showing a deleted line from a hunk when
 118   another hunk immediately begins where the earlier one ends.
 119   (merge aac3857 mk/combine-diff-context-horizon-fix later to maint).
 120
 121 * "git log --ancestry-path A...B" did not work as expected, as it did
 122   not pay attention to the fact that the merge base between A and B
 123   was the bottom of the range being specified.
 124   (merge a765499 kb/ancestry-path-threedots later to maint).
 125
 126 * Mac OS X does not like to write(2) more than INT_MAX number of
 127   bytes; work it around by chopping write(2) into smaller pieces.
 128   (merge 6c642a8 fc/macos-x-clipped-write later to maint).
 129
 130 * Newer MacOS X encourages the programs to compile and link with
 131   their CommonCrypto, not with OpenSSL.
 132   (merge be4c828 da/darwin later to maint).
 133
 134 * "git clone foo/bar:baz" cannot be a request to clone from a remote
 135   over git-over-ssh specified in the scp style.  This case is now
 136   detected and clones from a local repository at "foo/bar:baz".
 137   (merge 6000334 nd/clone-local-with-colon later to maint).
 138
 139 * When $HOME is misconfigured to point at an unreadable directory, we
 140   used to complain and die. Loosen the check.
 141   (merge 4698c8f jn/config-ignore-inaccessible later to maint).
 142
 143 * "git subtree" (in contrib/) had one codepath with loose error
 144   checks to lose data at the remote side.
 145   (merge 3212d56 jk/subtree-do-not-push-if-split-fails later to maint).
 146
 147 * "git fetch" into a shallow repository from a repository that does
 148   not know about the shallow boundary commits (e.g. a different fork
 149   from the repository the current shallow repository was cloned from)
 150   did not work correctly.
 151   (merge 71d5f93 mh/fetch-into-shallow later to maint).
 152
 153 * "git checkout foo" DWIMs the intended "upstream" and turns it into
 154   "git checkout -t -b foo remotes/origin/foo". This codepath has been
 155   updated to correctly take existing remote definitions into account.
 156   (merge 229177a jh/checkout-auto-tracking later to maint).
