   1Git v1.8.1 Release Notes
   2========================
   3
   4Backward compatibility notes
   5----------------------------
   6
   7In the next major release (not *this* one), we will change the
   8behavior 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, and
  17"git push" will warn about the upcoming change until you set this
  18variable in this release.
  19
  20"git branch --set-upstream" is deprecated and may be removed in a
  21relatively distant future.  "git branch [-u|--set-upstream-to]" has
  22been introduced with a saner order of arguments.

  25Updates since v1.8.0
  26--------------------

  28UI, Workflows & Features
  29
  30 * We used to have a workaround for a bug in ancient "less" that
  31   causes it to exit without any output when the terminal is resized.
  32   The bug has been fixed in "less" version 406 (June 2007), and the
  33   workaround has been removed in this release.
  34
  35 * Some documentation pages that used to ship only in the plain text
  36   format are now formatted in HTML as well.
  37
  38 * "git-prompt" scriptlet (in contrib/completion) can be told to paint
  39   pieces of the hints in the prompt string in colors.
  40
  41 * A new configuration variable "diff.context" can be used to
  42   give the default number of context lines in the patch output, to
  43   override the hardcoded default of 3 lines.
  44
  45 * "git config --get" used to diagnose presence of multiple
  46   definitions of the same variable in the same configuration file as
  47   an error, but it now applies the "last one wins" rule used by the
  48   internal configuration logic.  Strictly speaking, this may be an
  49   API regression but it is expected that nobody will notice it in
  50   practice.
  51
  52 * "git format-patch" learned the "--notes=<ref>" option to give
  53   notes for the commit after the three-dash lines in its output.
  54
  55 * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
  56   configuration set to "perl".
  57
  58 * "git replace -d <object>" now interprets <object>, instead of only
  59   accepting full hex object name.
  60
  61 * "git rm $submodule" used to punt on removing a submodule working
  62   tree to avoid losing the repository embedded in it.  Because
  63   recent git uses a mechanism to separate the submodule repository
  64   from the submodule working tree, "git rm" learned to detect this
  65   case and removes the submodule working tree when it is safe.
  66
  67 * "git submodule add" learned to add a new submodule at the same
  68   path as the path where an unrelated submodule was bound to in an
  69   existing revision via the "--name" option.
  70
  71 * "git submodule sync" learned the "--recursive" option.
  72
  73 * "git symbolic-ref" learned the "-d $symref" option to delete the
  74   named symbolic ref, which is more intuitive way to spell it than
  75   "update-ref -d --no-deref".
  76
  77
  78Foreign Interface
  79
  80 * "git cvsimport" can be told to record timezones (other than GMT)
  81   per-author via its author info file.
  82
  83 * The remote helper interface to interact with subversion
  84   repositories (one of the GSoC 2012 projects) has been merged.
  85
  86
  87Performance, Internal Implementation, etc.
  88
  89 * Compilation on Cygwin with newer header files are supported now.
  90
  91 * The logic to generate the initial advertisement from
  92   "upload-pack" (what is invoked by "git fetch" on the other side
  93   of the connection) to list what refs are available in the
  94   repository has been optimized.
  95
  96 * The logic to find set of attributes that match a given path has
  97   been optimized.
  98
  99 * Use preloadindex in "git diff-index" and "git update-index", which
 100   has a nice speedup on systems with slow stat calls (and even on
 101   Linux).
 102
 103
 104Also contains minor documentation updates and code clean-ups.

 107Fixes since v1.8.0
 108------------------
 109
 110Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
 111track are contained in this release (see release notes to them for
 112details).
 113
 114 * The configuration parser had an unnecessary hardcoded limit on
 115   variable names that was not checked consistently.
 116   (merge 0971e99 bw/config-lift-variable-name-length-limit later to maint).
 117
 118 * The "say" function in the test scaffolding incorrectly allowed
 119   "echo" to interpret "\a" as if it were a C-string asking for a
 120   BEL output.
 121   (merge 7bc0911 jc/test-say-color-avoid-echo-escape later to maint).
 122
 123 * "git mergetool" feeds /dev/null as a common ancestor when dealing
 124   with an add/add conflict, but p4merge backend cannot handle
 125   it. Work it around by passing a temporary empty file.
 126   (merge 3facc60 da/mergetools-p4 later to maint).
 127
 128 * "git log -F -E --grep='<ere>'" failed to use the given <ere>
 129   pattern as extended regular expression, and instead looked for the
 130   string literally.
 131   (merge 727b6fc jc/grep-pcre-loose-ends~1 later to maint).
 132
 133 * "git grep -e pattern <tree>" asked the attribute system to read
 134   "<tree>:.gitattributes" file in the working tree, which was
 135   nonsense.
 136   (merge 55c6168 nd/grep-true-path later to maint).
 137
 138 * A symbolic ref refs/heads/SYM was not correctly removed with "git
 139   branch -d SYM"; the command removed the ref pointed by SYM
 140   instead.
 141   (merge 13baa9f rs/branch-del-symref later to maint).
 142
 143 * Update "remote tracking branch" in the documentation to
 144   "remote-tracking branch".
 145   (merge a6d3bde mm/maint-doc-remote-tracking later to maint).
 146
 147 * "git pull --rebase" run while the HEAD is detached tried to find
 148   the upstream branch of the detached HEAD (which by definition
 149   does not exist) and emitted unnecessary error messages.
 150   (merge e980765 ph/pull-rebase-detached later to maint).
 151
 152 * The refs/replace hierarchy was not mentioned in the
 153   repository-layout docs.
 154   (merge 11fbe18 po/maint-refs-replace-docs later to maint).
 155
 156 * Various rfc2047 quoting issues around a non-ASCII name on the
 157   From: line in the output from format-patch have been corrected.
 158   (merge 25dc8da js/format-2047 later to maint).
 159
 160 * Sometimes curl_multi_timeout() function suggested a wrong timeout
 161   value when there is no file descriptor to wait on and the http
 162   transport ended up sleeping for minutes in select(2) system call.
 163   A workaround has been added for this.
 164   (merge 7202b81 sz/maint-curl-multi-timeout later to maint).
 165
 166 * For a fetch refspec (or the result of applying wildcard on one),
 167   we always want the RHS to map to something inside "refs/"
 168   hierarchy, but the logic to check it was not exactly right.
 169   (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
 170
 171 * "git diff -G<pattern>" did not honor textconv filter when looking
 172   for changes.
 173   (merge b1c2f57 jk/maint-diff-grep-textconv later to maint).
 174
 175 * Some HTTP servers ask for auth only during the actual packing phase
 176   (not in ls-remote phase); this is not really a recommended
 177   configuration, but the clients used to fail to authenticate with
 178   such servers.
 179   (merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
 180
 181 * "git p4" used to try expanding malformed "$keyword$" that spans
 182   across multiple lines.
 183   (merge 6b2bf41 pw/maint-p4-rcs-expansion-newline later to maint).
 184
 185 * Syntax highlighting in "gitweb" was not quite working.
 186   (merge 048b399 rh/maint-gitweb-highlight-ext later to maint).
 187
 188 * RSS feed from "gitweb" had a xss hole in its title output.
 189   (merge 0f0ecf6 jk/maint-gitweb-xss later to maint).
 190
 191 * "git config --path $key" segfaulted on "[section] key" (a boolean
 192   "true" spelled without "=", not "[section] key = true").
 193   (merge 962c38e cn/config-missing-path later to maint).
 194
 195 * "git checkout -b foo" while on an unborn branch did not say
 196   "Switched to a new branch 'foo'" like other cases.
 197   (merge afa8c07 jk/checkout-out-of-unborn later to maint).
