   1Git v1.8.2 Release Notes
   2========================
   3
   4Backward compatibility notes
   5----------------------------
   6
   7In the upcoming major release (tentatively called 1.8.2), we will
   8change the behavior of the "git push" command.
   9
  10When "git push [$there]" does not say what to push, we have used the
  11traditional "matching" semantics so far (all your branches were sent
  12to the remote as long as there already are branches of the same name
  13over there).  We will use the "simple" semantics that pushes the
  14current branch to the branch with the same name, only when the current
  15branch is set to integrate with that remote branch.  There is a user
  16preference configuration variable "push.default" to change this.

  19Updates since v1.8.1
  20--------------------
  21
  22UI, Workflows & Features
  23
  24 * Initial ports to QNX and z/OS UNIX System Services have started.
  25
  26 * Output from the tests is coloured using "green is okay, yellow is
  27   questionable, red is bad and blue is informative" scheme.
  28
  29 * In bare repositories, "git shortlog" and other commands now read
  30   mailmap files from the tip of the history, to help running these
  31   tools in server settings.
  32
  33 * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the
  34   "--format=" option of "git log" and friends can be disabled when
  35   the output is not sent to a terminal by prefixing them with
  36   "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)".
  37
  38 * Scripts can ask Git that wildcard patterns in pathspecs they give do
  39   not have any significance, i.e. take them as literal strings.
  40
  41 * The pathspec code learned to grok "foo/**/bar" as a pattern that
  42   matches "bar" in 0-or-more levels of subdirectory in "foo".
  43
  44 * "git blame" (and "git diff") learned the "--no-follow" option.
  45
  46 * "git cherry-pick" can be used to replay a root commit to an unborn
  47   branch.
  48
  49 * "git commit" can be told to use --cleanup=whitespace by setting the
  50   configuration variable commit.cleanup to 'whitespace'.
  51
  52 * "git fetch --mirror" and fetch that uses other forms of refspec
  53   with wildcard used to attempt to update a symbolic ref that match
  54   the wildcard on the receiving end, which made little sense (the
  55   real ref that is pointed at by the symbolic ref would be updated
  56   anyway).  Symbolic refs no longer are affected by such a fetch.
  57
  58 * "git format-patch" now detects more cases in which a whole branch
  59   is being exported, and uses the description for the branch, when
  60   asked to write a cover letter for the series.
  61
  62 * "git format-patch" learned "-v $count" option, and prepends a
  63   string "v$count-" to the names of its output files, and also
  64   automatically sets the subject prefix to "PATCH v$count". This
  65   allows patches from rerolled series to be stored under different
  66   names and makes it easier to reuse cover letter messsages.
  67
  68 * "git log" and friends can be told with --use-mailmap option to
  69   rewrite the names and email addresses of people using the mailmap
  70   mechanism.
  71
  72 * "git push" now requires "-f" to update a tag, even if it is a
  73   fast-forward, as tags are meant to be fixed points.
  74
  75 * When "git rebase" fails to generate patches to be applied (e.g. due
  76   to oom), it failed to detect the failure and instead behaved as if
  77   there were nothing to do.  A workaround to use a temporary file has
  78   been applied, but we probably would want to revisit this later, as
  79   it hurts the common case of not failing at all.
  80
  81 * "git submodule" started learning a new mode to integrate with the
  82   tip of the remote branch (as opposed to integrating with the commit
  83   recorded in the superproject's gitlink).
  84
  85
  86Foreign Interface
  87
  88 * "git fast-export" has been updated for its use in the context of
  89   the remote helper interface.
  90
  91 * A new remote helper to interact with bzr has been added to contrib/.
  92
  93
  94Performance, Internal Implementation, etc.
  95
  96 * "git fsck" has been taught to be pickier about entries in tree
  97   objects that should not be there, e.g. ".", ".git", and "..".
  98
  99 * Matching paths with common forms of pathspecs that contain wildcard
 100   characters has been optimized further.
 101
 102 * The implementation of "imap-send" has been updated to reuse xml
 103   quoting code from http-push codepath.
 104
 105 * There is a simple-minded checker for the test scripts in t/
 106   directory to catch most common mistakes (it is not enabled by
 107   default).
 108
 109
 110Also contains minor documentation updates and code clean-ups.

 113Fixes since v1.8.1
 114------------------
 115
 116Unless otherwise noted, all the fixes since v1.8.1 in the maintenance
 117track are contained in this release (see release notes to them for
 118details).
 119
 120 * An element on GIT_CEILING_DIRECTORIES list that does not name the
 121   real path to a directory (i.e. a symbolic link) could have caused
 122   the GIT_DIR discovery logic to escape the ceiling.
 123   (merge 059b379 mh/ceiling later to maint).
 124
 125 * When attempting to read the XDG-style $HOME/.config/git/config and
 126   finding that $HOME/.config/git is a file, we gave a wrong error
 127   message, instead of treating the case as "a custom config file does
 128   not exist there" and moving on.
 129   (merge 8f2bbe4 jn/warn-on-inaccessible-loosen later to maint).
 130
 131 * The behaviour visible to the end users was confusing, when they
 132   attempt to kill a process spawned in the editor that was in turn
 133   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
 134   signal and die.  We ignore these signals now.
 135   (merge 1250857 pf/editor-ignore-sigint later to maint).
 136
 137 * A child process that was killed by a signal (e.g. SIGINT) was
 138   reported in an inconsistent way depending on how the process was
 139   spawned by us, with or without a shell in between.
 140   (merge 709ca73 jk/unify-exit-code-by-receiving-signal later to maint).
 141
 142 * After failing to create a temporary file using mkstemp(), failing
 143   pathname was not reported correctly on some platforms.
 144   (merge f7be59b jc/mkstemp-more-careful-error-reporting later to maint).
 145
 146 * The attribute mechanism didn't allow limiting attributes to be
 147   applied to only a single directory itself with "path/" like the
 148   exclude mechanism does.
 149   (merge 94bc671 ja/directory-attrs later to maint).
 150
 151 * "git apply" misbehaved when fixing whitespace breakages by removing
 152   excess trailing blank lines.
 153   (merge 5de7166 jc/apply-trailing-blank-removal later to maint).
 154
 155 * A tar archive created by "git archive" recorded a directory in a
 156   way that made NetBSD's implementation of "tar" sometimes unhappy.
 157   (merge 22f0dcd rs/leave-base-name-in-name-field-of-tar later to maint).
 158
 159 * "git archive" did not record uncompressed size in the header when
 160   streaming a zip archive, which confused some implementations of unzip.
 161   (merge 5ea2c84 rs/zip-with-uncompressed-size-in-the-header later to maint).
 162
 163 * When "git clone --separate-git-dir=$over_there" is interrupted, it
 164   failed to remove the real location of the $GIT_DIR it created.
 165   This was most visible when interrupting a submodule update.
 166   (merge 9be1980 jl/interrupt-clone-remove-separate-git-dir later to maint).
 167
 168 * The way "git svn" asked for password using SSH_ASKPASS and
 169   GIT_ASKPASS was not in line with the rest of the system.
 170   (merge e9263e4 ss/svn-prompt later to maint).
 171
 172 * The --graph code fell into infinite loop when asked to do what the
 173   code did not expect.
 174   (merge 656197a mk/maint-graph-infinity-loop later to maint).
 175
 176 * http transport was wrong to ask for the username when the
 177   authentication is done by certificate identity.
 178   (merge 75e9a40 rb/http-cert-cred-no-username-prompt later to maint).
 179
 180 * "git pack-refs" that ran in parallel to another process that
 181   created new refs had a nasty race.
 182   (merge b3f1280 jk/repack-ref-racefix later to maint).
 183
 184 * After "git add -N" and then writing a tree object out of the
 185   index, the cache-tree data structure got corrupted.
 186   (merge eec3e7e nd/invalidate-i-t-a-cache-tree later to maint).
 187
 188 * "git merge --no-edit" computed who were involved in the work done
 189   on the side branch, even though that information is to be discarded
 190   without getting seen in the editor.
 191   (merge 9bcbb1c jc/maint-fmt-merge-msg-no-edit-lose-credit later to maint).
 192
 193 * "git merge" started calling prepare-commit-msg hook like "git
 194   commit" does some time ago, but forgot to pay attention to the exit
 195   status of the hook.
 196   (merge 3e4141d ap/merge-stop-at-prepare-commit-msg-failure later to maint).
 197
 198 * When users spell "cc:" in lowercase in the fake "header" in the
 199   trailer part, "git send-email" failed to pick up the addresses from
 200   there. As e-mail headers field names are case insensitive, this
 201   script should follow suit and treat "cc:" and "Cc:" the same way.
 202   (merge 6310071 nz/send-email-headers-are-case-insensitive later to maint).
 203
 204 * Output from "git status --ignored" showed an unexpected interaction
 205   with "--untracked".
 206   (merge a45fb69 ap/status-ignored-in-ignored-directory later to maint).
 207
 208 * "gitweb", when sorting by age to show repositories with new
 209   activities first, used to sort repositories with absolutely
 210   nothing in it early, which was not very useful.
 211   (merge 28dae18 md/gitweb-sort-by-age later to maint).
 212
 213 * "gitweb"'s code to sanitize control characters before passing it to
 214   "highlight" filter lost known-to-be-safe control characters by
 215   mistake.
 216   (merge 0e901d2 os/gitweb-highlight-uncaptured later to maint).
 217
 218 * When a line to be wrapped has a solid run of non space characters
 219   whose length exactly is the wrap width, "git shortlog -w" failed
 220   to add a newline after such a line.
 221   (merge e0db176 sp/shortlog-missing-lf later to maint).
 222
 223 * Command line completion leaked an unnecessary error message while
 224   looking for possible matches with paths in <tree-ish>.
 225   (merge ca87dd6 ds/completion-silence-in-tree-path-probe later to maint).
 226
 227 * Command line completion for "tcsh" emitted an unwanted space
 228   after completing a single directory name.
 229   (merge 92f1c04 mk/complete-tcsh later to maint).
 230
 231 * Some shells do not behave correctly when IFS is unset; work it
 232   around by explicitly setting it to the default value.
 233   (merge 393050c jc/maint-fbsd-sh-ifs-workaround later to maint).
 234
 235 * Some scripted programs written in Python did not get updated when
 236   PYTHON_PATH changed.
 237   (cherry-pick 96a4647fca54031974cd6ad1 later to maint).
 238
 239 * When autoconf is used, any build on a different commit always ran
 240   "config.status --recheck" even when unnecessary.
 241   (merge 1226504 jn/less-reconfigure later to maint).
 242
 243 * We have been carrying a translated and long-unmaintained copy of an
 244   old version of the tutorial; removed.
 245   (merge 0a85441 ta/remove-stale-translated-tut later to maint).
 246
 247 * t4014, t9502 and t0200 tests had various portability issues that
 248   broke on OpenBSD.
 249   (merge 27f6342 jc/maint-test-portability later to maint).
 250
 251 * t9020 and t3600 tests had various portability issues.
 252   (merge 5a02966 jc/test-portability later to maint).
 253
 254 * t9200 runs "cvs init" on a directory that already exists, but a
 255   platform can configure this fail for the current user (e.g. you
 256   need to be in the cvsadmin group on NetBSD 6.0).
 257   (merge 8666df0 jc/test-cvs-no-init-in-existing-dir later to maint).
 258
 259 * t9020 and t9810 had a few non-portable shell script construct.
 260   (merge 2797914 tb/test-t9020-no-which later to maint).
 261   (merge 6f4e505 tb/test-t9810-no-sed-i later to maint).
