   1Git v1.7.11 Release Notes
   2=========================
   3
   4Updates since v1.7.10
   5---------------------
   6
   7UI, Workflows & Features
   8
   9 * A third-party tool "git subtree" is distributed in contrib/
  10
  11 * Error messages given when @{u} is used for a branch without its
  12   upstream configured have been clatified.
  13
  14 * Even with "-q"uiet option, "checkout" used to report setting up
  15   tracking.  Also "branch" learned the "-q"uiet option to squelch
  16   informational message.
  17
  18 * The smart-http backend used to always override GIT_COMMITTER_*
  19   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
  20   now preserved when set.
  21
  22 * "include.path" mechanism of the configuration files learned to
  23   understand "~/path" and "~user/path".
  24
  25 * "git am" learned the "--include" option, which is an opposite of
  26   existing the "--exclude" option.
  27
  28 * When "git am -3" needs to fall back to an application to a
  29   synthesized preimage followed by a 3-way merge, the paths that
  30   needed such treatment are now reported to the end user, so that the
  31   result in them can be eyeballed with extra care.
  32
  33 * The "fmt-merge-msg" command learns to list the primary contributors
  34   involved in the side topic you are merging.
  35
  36 * The cases "git push" fails due to non-ff can be broken into three
  37   categories; each case is given a separate advise message.
  38
  39 * "git push --recurse-submodules" learned to optionally look into the
  40   histories of submodules bound to the superproject and push them
  41   out.
  42
  43 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
  44   based on the commit date.
  45
  46 * "gitweb" learned to highlight the patch it outputs even more.
  47
  48Foreign Interface
  49
  50 * "git svn" used to die with unwanted SIGPIPE when talking with HTTP
  51   server that uses keep-alive.
  52
  53 * "git svn" learned to use platform specific authentication
  54   providers, e.g. gnome-keyring, kwallet, etc.
  55
  56 * "git p4" has been moved out of contrib/ area.
  57
  58Performance
  59
  60 * "git apply" had some memory leaks plugged.
  61
  62 * "git repack" used to write out unreachable objects as loose objects
  63   when repacking, even if such loose objects will immediately pruned
  64   due to its age.
  65
  66 * Setting up a revision traversal with many starting points was
  67   inefficient as these were placed in a date-order priority queue
  68   one-by-one.  Now they are collected in the queue unordered first,
  69   and sorted immediately before getting used.
  70
  71Internal Implementation (please report possible regressions)
  72
  73 * "git rev-parse --show-prefix" used to emit nothing when run at the
  74   top-level of the working tree, but now it gives a blank line.
  75
  76 * Minor memory leak during unpack_trees (hence "merge" and "checkout"
  77   to check out another branch) has been plugged.
  78
  79 * More lower-level commands learned to use the streaming API to read
  80   from the object store without keeping everything in core.
  81
  82 * Because "sh" on the user's PATH may be utterly broken on some
  83   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
  84   spawning an external command (not applicable to Windows port).
  85
  86 * The API to iterate over refs/ hierarchy has been tweaked to allow
  87   walking only a subset of it more efficiently.
  88
  89Also contains minor documentation updates and code clean-ups.

  92Fixes since v1.7.10
  93-------------------
  94
  95Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
  96releases are contained in this release (see release notes to them for
  97details).
  98
  99 * The test scaffolding for git-daemon was flaky.
 100   (merge 46e3581 js/daemon-test-race-fix later to maint).
 101
 102 * The test scaffolding for fast-import was flaky.
 103   (merge 7fb8e16 pw/t5800-import-race-fix later to maint).
 104
 105 * Octopus merge strategy did not reduce heads that are recorded in the
 106   final commit correctly.
 107   (merge 5802f81 jc/merge-reduce-parents-early later to maint).
 108
 109 * In the older days, the header "Conflicts:" in "cherry-pick" and
 110   "merge" was separated by a blank line from the list of paths that
 111   follow for readability, but when "merge" was rewritten in C, we lost
 112   it by mistake. Remove the newline from "cherry-pick" to make them
 113   match again.
 114   (merge 5112068 rt/cherry-revert-conflict-summary later to maint).
 115
 116 * The filesystem boundary was not correctly reported when .git
 117   directory discovery stopped at a mount point.
 118   (merge 2565b43 cb/maint-report-mount-point-correctly-in-setup later to maint).
 119
 120 * The command line parser choked "git cherry-pick $name" when $name
 121   can be both revision name and a pathname, even though $name can
 122   never be a path in the context of the command.
 123   (merge 6d5b93f cb/cherry-pick-rev-path-confusion later to maint).
 124
 125 * HTTP transport that requires authentication did not work correctly
 126   when multiple connections are used simultaneously.
 127   (merge 6f4c347 cb/http-multi-curl-auth later to maint).
 128
 129 * The i18n of error message "git stash save" was not properly done.
 130   (merge ed3c400 rl/maint-stash-i18n-save-error later to maint).
 131
 132 * The report from "git fetch" said "new branch" even for a non branch
 133   ref.
 134   (merge 0997ada mb/fetch-call-a-non-branch-a-ref later to maint).
 135
 136 * The "diff --no-index" codepath used limited-length buffers, risking
 137   pathnames getting truncated.  Update it to use the strbuf API.
 138   (merge 875b91b jm/maint-strncpy-diff-no-index later to maint).
 139
 140 * The parser in "fast-import" did not diagnose ":9" style references
 141   that is not followed by required SP/LF as an error.
 142   (merge 06454cb pw/fast-import-dataref-parsing later to maint).
 143
 144 * When "git fetch" encounters repositories with too many references,
 145   the command line of "fetch-pack" that is run by a helper
 146   e.g. remote-curl, may fail to hold all of them. Now such an
 147   internal invocation can feed the references through the standard
 148   input of "fetch-pack".
 149   (merge 7103d25 it/fetch-pack-many-refs later to maint).
 150
 151 * "git fetch" that recurses into submodules on demand did not check
 152   if it needs to go into submodules when non branches (most notably,
 153   tags) are fetched.
 154   (merge a6801ad jl/maint-submodule-recurse-fetch later to maint).
 155
 156 * "git blame" started missing quite a few changes from the origin
 157   since we stopped using the diff minimalization by default in v1.7.2
 158   era.
 159   (merge 059a500 jc/maint-blame-minimal later to maint).
 160
 161 * "log -p --graph" used with "--stat" had a few formatting error.
 162   (merge e2c5966 lp/maint-diff-three-dash-with-graph later to maint).
 163
 164 * Giving "--continue" to a conflicted "rebase -i" session skipped a
 165   commit that only results in changes to submodules.
 166   (merge a6754cd jk/rebase-i-submodule-conflict-only later to maint).
