   1Git v1.8.3 Release Notes
   2========================
   3
   4Backward compatibility notes (for Git 2.0)
   5------------------------------------------
   6
   7When "git push [$there]" does not say what to push, we have used the
   8traditional "matching" semantics so far (all your branches were sent
   9to the remote as long as there already are branches of the same name
  10over there).  In Git 2.0, the default will change to the "simple"
  11semantics that pushes the current branch to the branch with the same
  12name, only when the current branch is set to integrate with that
  13remote branch.  There is a user preference configuration variable
  14"push.default" to change this.  If you are an old-timer who is used
  15to the "matching" semantics, you can set it to "matching" to keep the
  16traditional behaviour.  If you want to live in the future early,
  17you can set it to "simple" today without waiting for Git 2.0.
  18
  19When "git add -u" and "git add -A", that does not specify what paths
  20to add on the command line is run from inside a subdirectory, these
  21commands will operate on the entire tree in Git 2.0 for consistency
  22with "git commit -a" and other commands. Because there will be no
  23mechanism to make "git add -u" behave as if "git add -u .", it is
  24important for those who are used to "git add -u" (without pathspec)
  25updating the index only for paths in the current subdirectory to start
  26training their fingers to explicitly say "git add -u ." when they mean
  27it before Git 2.0 comes.

  30Updates since v1.8.2
  31--------------------
  32
  33UI, Workflows & Features
  34
  35 * When the interactive access to git-shell is not enabled, it issues
  36   a message meant to help the system admininstrator to enable it.
  37   An explicit way to help the end users who connect to the service by
  38   issuing custom messages to refuse such an access has been added.
  39
  40 * In addition to the case where the user edits the log message with
  41   the "e)dit" option of "am -i", replace the "Applying: this patch"
  42   message with the final log message contents after applymsg hook
  43   munges it.
  44
  45 * "git status" suggests users to look into using --untracked=no option
  46   when it takes too long.
  47
  48 * "git status" shows a bit more information to "git status" during a
  49   rebase/bisect session.
  50
  51 * "git fetch" learned to fetch a commit at the tip of an unadvertised
  52   ref by specifying a raw object name from the command line when the
  53   server side supports this feature.
  54
  55 * "git count-objects -v" learned to report leftover temporary
  56   packfiles and other garbage in the object store.
  57
  58 * A new read-only credential helper (in contrib/) to interact with
  59   the .netrc/.authinfo files has been added.
  60
  61 * "git send-email" can be used with the credential helper system.
  62
  63 * There was no Porcelain way to say "I no longer am interested in
  64   this submodule", once you express your interest in a submodule with
  65   "submodule init".  "submodule deinit" is the way to do so.
  66
  67 * "git pull --rebase" learned to pass "-v/-q" options to underlying
  68   "git rebase".
  69
  70 * The new "--follow-tags" option tells "git push" to push relevant
  71   annotated tags when pushing branches out.
  72
  73 * "git mergetool" now feeds files to the "p4merge" backend in the
  74   order that matches the p4 convention, where "theirs" is usually
  75   shown on the left side, which is the opposite from other backend
  76   expects.
  77
  78 * "show/log" now honors gpg.program configuration just like other
  79   parts of the code that use GnuPG.
  80
  81 * "git log" that shows the difference between the parent and the
  82   child has been optimized somewhat.
  83
  84
  85Performance, Internal Implementation, etc.
  86
  87 * Updates for building under msvc.
  88
  89 * A few codepaths knew how much data they need to put in the
  90   hashtables they use upfront, but still started from a small table
  91   repeatedly growing and rehashing.
  92
  93 * The API to walk reflog entries from the latest to older, which was
  94   necessary for operations such as "git checkout -", was cumbersome
  95   to use correctly and also inefficient.
  96
  97 * Codepaths that inspect log-message-to-be and decide when to add a
  98   new Signed-off-by line in various commands have been consolidated.
  99
 100 * The pkt-line API, implementation and its callers have been cleaned
 101   up to make them more robust.
 102
 103 * Cygwin port has a faster-but-lying lstat(2) emulation whose
 104   incorrectness does not matter in practice except for a few
 105   codepaths, and setting permission bits to directories is a codepath
 106   that needs to use a more correct one.
 107
 108
 109Also contains minor documentation updates and code clean-ups.

 112Fixes since v1.8.2
 113------------------
 114
 115Unless otherwise noted, all the fixes since v1.8.2 in the maintenance
 116track are contained in this release (see release notes to them for
 117details).
 118
 119 * "index-pack --fix-thin" used uninitialize value to compute delta
 120   depths of objects it appends to the resulting pack.
 121   (merge 57165db jk/index-pack-correct-depth-fix later to maint).
 122
 123 * "index-pack --verify-stat" used a few counters outside protection
 124   of mutex, possibly showing incorrect numbers.
 125   (merge 8f82aad nd/index-pack-threaded-fixes later to maint).
 126
 127 * The code to keep track of what directory names are known to Git on
 128   platforms with case insensitive filesystems can get confused upon a
 129   hash collision between these pathnames and looped forever.
 130   (merge 2092678 kb/name-hash later to maint).
 131
 132 * Annotated tags outside refs/tags/ hierarchy were not advertised
 133   correctly to the ls-remote and fetch with recent version of Git.
 134   (merge c29c46f jk/fully-peeled-packed-ref later to maint).
 135
 136 * Recent optimization broke shallow clones.
 137   (merge f59de5d jk/peel-ref later to maint).
 138
 139 * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
 140   instead the parser kept reading beyond the end of the string.
 141   (merge f612a67 lf/setup-prefix-pathspec later to maint).
 142
 143 * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
 144   creating a new tag (i.e. not overwriting nor updating).
 145   (merge 3ae851e ph/tag-force-no-warn-on-creation later to maint).
 146
 147 * "git p4" did not behave well when the path to the root of the P4
 148   client was not its real path.
 149   (merge bbd8486 pw/p4-symlinked-root later to maint).
 150
 151 * "git archive" reports a failure when asked to create an archive out
 152   of an empty tree.  It would be more intuitive to give an empty
 153   archive back in such a case.
 154   (merge bd54cf1 jk/empty-archive later to maint).
 155
 156 * When "format-patch" quoted a non-ascii strings on the header files,
 157   it incorrectly applied rfc2047 and chopped a single character in
 158   the middle of it.
 159   (merge 6cd3c05 ks/rfc2047-one-char-at-a-time later to maint).
 160
 161 * An aliased command spawned from a bare repository that does not say
 162   it is bare with "core.bare = yes" is treated as non-bare by mistake.
 163   (merge 2cd83d1 jk/alias-in-bare later to maint).
 164
 165 * In "git reflog expire", REACHABLE bit was not cleared from the
 166   correct objects.
 167
 168 * The logic used by "git diff -M --stat" to shorten the names of
 169   files before and after a rename did not work correctly when the
 170   common prefix and suffix between the two filenames overlapped.
 171
 172 * The "--match=<pattern>" option of "git describe", when used with
 173   "--all" to allow refs that are not annotated tags to be used as a
 174   base of description, did not restrict the output from the command
 175   to those that match the given pattern.
 176   (merge 46e1d6e jc/describe later to maint).
 177
 178 * Clarify in the documentation "what" gets pushed to "where" when the
 179   command line to "git push" does not say these explicitly.
 180
 181 * The "--color=<when>" argument to the commands in the diff family
 182   was described poorly.
 183
 184 * The arguments given to pre-rebase hook were not documented.
 185
 186 * The v4 index format was not documented.
 187
 188 * The "--match=<pattern>" argument "git describe" takes uses glob
 189   pattern but it wasn't obvious from the documentation.
 190
 191 * Some sources failed to compile on systems that lack NI_MAXHOST in
 192   their system header (e.g. z/OS).
 193
 194 * Add an example use of "--env-filter" in "filter-branch"
 195   documentation.
 196
 197 * "git bundle verify" did not say "records a complete history" for a
 198   bundle that does not have any prerequisites.
 199
 200 * In the v1.8.0 era, we changed symbols that do not have to be global
 201   to file scope static, but a few functions in graph.c were used by
 202   CGit from sideways bypassing the entry points of the API the
 203   in-tree users use.
 204
 205 * "git update-index -h" did not do the usual "-h(elp)" thing.
 206
 207 * "git index-pack" had a buffer-overflow while preparing an
 208   informational message when the translated version of it was too
 209   long.
 210
 211 * 'git commit -m "$msg"' used to add an extra newline even when
 212   $msg already ended with one.
 213   (merge 46fbf75 bc/commit-complete-lines-given-via-m-option later to maint).
 214
 215 * The SSL peer verification done by "git imap-send" did not ask for
 216   Server Name Indication (RFC 4366), failing to connect SSL/TLS
 217   sites that serve multiple hostnames on a single IP.
 218
 219 * perl/Git.pm::cat_blob slurped everything in core only to write it
 220   out to a file descriptor, which was not a very smart thing to do.
 221
 222 * "git branch" did not bother to check nonsense command line
 223   parameters and issue errors in many cases.
 224
 225 * Verification of signed tags were not done correctly when not in C
 226   or en/US locale.
 227   (merge 0174eea mg/gpg-interface-using-status later to maint).
 228
 229 * Some platforms and users spell UTF-8 differently; retry with the
 230   most official "UTF-8" when the system does not understand the
 231   user-supplied encoding name that are the common alternative
 232   spellings of UTF-8.
 233
 234 * When export-subst is used, "zip" output recorded incorrect
 235   size of the file.
 236
 237 * "git am $maildir/" applied messages in an unexpected order; sort
 238   filenames read from the maildir/ in a way that is more likely to
 239   sort messages in the order the writing MUA meant to, by sorting
 240   numeric segment in numeric order and non-numeric segment in
 241   alphabetical order.
 242
 243 * "git submodule update", when recursed into sub-submodules, did not
 244   acccumulate the prefix paths.
