Git v1.7.11 Release Notes
=========================

Updates since v1.7.10
---------------------

UI, Workflows & Features

 * A third-party tool "git subtree" is distributed in contrib/

 * Even with "-q"uiet option, "checkout" used to report setting up
   tracking.  Also "branch" learned the "-q"uiet option to squelch
   informational message.

 * The smart-http backend used to always override GIT_COMMITTER_*
   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
   now preserved when set.

 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
   based on the commit date.

Foreign Interface


Performance


Internal Implementation (please report possible regressions)

 * Minor memory leak during unpack_trees (hence "merge" and "checkout"
   to check out another branch) has been plugged.

 * More lower-level commands learned to use the streaming API to read
   from the object store without keeping everything in core.

 * Because "sh" on the user's PATH may be utterly broken on some
   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
   spawning an external command.

Also contains minor documentation updates and code clean-ups.


Fixes since v1.7.10
-------------------

Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
releases are contained in this release (see release notes to them for
details).

 * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
   working trees of independent git repositories that exist in the
   current project working tree from getting removed, but the
   protection applied only to such working trees that are at the
   top-level of the current project by mistake.
   (merge ae2f203 jc/maint-clean-nested-worktree-in-subdir later to maint).

 * Rename detection logic used to match two empty files as renames
   during merge-recursive, leading unnatural mismerges.
   (merge 4f7cb99 jk/diff-no-rename-empty later to maint).

 * An age-old corner case bug in combine diff (only triggered with -U0
   and the hunk at the beginning of the file needs to be shown) has
   been fixed.
   (merge e5e9b56 rs/combine-diff-zero-context-at-the-beginning later to maint).

 * When "git commit --template F" errors out because the user did not
   touch the message, it claimed that it aborts due to "empty
   message", which was utterly wrong.
   (merge 1f08c2c jc/commit-unedited-template later to maint).

 * "git add -p" is not designed to deal with unmerged paths but did
   not exclude them and tried to apply funny patches only to fail.
   (merge 4066bd6 jk/add-p-skip-conflicts later to maint).

 * "git commit --author=$name" did not tell the name that was being
   recorded in the resulting commit to hooks, even though it does do
   so when the end user overrode the authorship via the
   "GIT_AUTHOR_NAME" environment variable.
   (merge 7dfe8ad jc/commit-hook-authorship later to maint).

 * The regexp configured with diff.wordregex was incorrectly reused
   across files.
   (merge 6440d34 tr/maint-word-diff-regex-sticky later to maint).

 * Running "notes merge --commit" failed to perform correctly when run
   from any directory inside $GIT_DIR/.  When "notes merge" stops with
   conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
   to resolve it.
   (merge dabba59 jh/notes-merge-in-git-dir-worktree later to maint).
