Git v1.7.10 Release Notes
=========================
+Compatibility Notes
+-------------------
+
+ * From this release on, the "git merge" command in an interactive
+ session will start an editor when it automatically resolves the
+ merge for the user to explain the resulting commit, just like the
+ "git commit" command does when it wasn't given a commit message.
+
+ If you have a script that runs "git merge" and keeps its standard
+ input and output attached to the user's terminal, and if you do not
+ want the user to explain the resulting merge commits, you can
+ export GIT_MERGE_AUTOEDIT environment variable set to "no", like
+ this:
+
+ #!/bin/sh
+ GIT_MERGE_AUTOEDIT=no
+ export GIT_MERGE_AUTOEDIT
+
+ to disable this behaviour (if you want your users to explain their
+ merge commits, you do not have to do anything). Alternatively, you
+ can give the "--no-edit" option to individual invocations of the
+ "git merge" command if you know everybody who uses your script has
+ Git v1.7.8 or newer.
+
+ * The "--binary/-b" options to "git am" have been a no-op for quite a
+ while and were deprecated in mid 2008 (v1.6.0). When you give these
+ options to "git am", it will now warn and ask you not to use them.
+
+
Updates since v1.7.9
--------------------
* A content filter (clean/smudge) used to be just a way to make the
recorded contents "more useful", and allowed to fail; a filter can
- new optionally be marked as "required".
+ now optionally be marked as "required".
* Options whose names begin with "--no-" (e.g. the "--no-verify"
option of the "git commit" command) can be negated by omitting
"no-" from its name, e.g. "git commit --verify".
* "git am" learned to pass "-b" option to underlying "git mailinfo", so
- that bracketed string other than "PATCH" at the beginning can be kept.
+ that a bracketed string other than "PATCH" at the beginning can be kept.
* "git clone" learned "--single-branch" option to limit cloning to a
- single branch (surprise!).
+ single branch (surprise!); tags that do not point into the history
+ of the branch are not fetched.
* "git clone" learned to detach the HEAD in the resulting repository
- when the source repository's HEAD does not point to a branch.
+ when the user specifies a tag with "--branch" (e.g., "--branch=v1.0").
+ Clone also learned to print the usual "detached HEAD" advice in such
+ a case, similar to "git checkout v1.0".
* When showing a patch while ignoring whitespace changes, the context
lines are taken from the postimage, in order to make it easier to
view the output.
+ * "git diff --stat" learned to adjust the width of the output on
+ wider terminals, and give more columns to pathnames as needed.
+
* "diff-highlight" filter (in contrib/) was updated to produce more
aesthetically pleasing output.
* "fsck" learned "--no-dangling" option to omit dangling object
information.
+ * "git log -G" and "git log -S" learned to pay attention to the "-i"
+ option. With "-i", "log -G" ignores the case when finding patch
+ hunks that introduce or remove a string that matches the given
+ pattern. Similarly with "-i", "log -S" ignores the case when
+ finding the commit the given block of text appears or disappears
+ from the file.
+
* "git merge" in an interactive session learned to spawn the editor
by default to let the user edit the auto-generated merge message,
to encourage people to explain their merges better. Legacy scripts
Both "git merge" and "git pull" can be given --no-edit from the
command line to accept the auto-generated merge message.
+ * The advice message given when the user didn't give enough clue on
+ what to merge to "git pull" and "git merge" has been updated to
+ be more concise and easier to understand.
+
* "git push" learned the "--prune" option, similar to "git fetch".
+ * The whole directory that houses a top-level superproject managed by
+ "git submodule" can be moved to another place.
+
* "git symbolic-ref" learned the "--short" option to abbreviate the
refname it shows unambiguously.

* "gitweb" allows intermediate entries in the directory hierarchy

list of projects inside that directory.
* "gitweb" learned to read various pieces of information for the
* Project search in "gitweb" shows the substring that matched in the
project name and description highlighted.
+ * A new script "diffall" is added to contrib/; it drives an
+ external tool to perform a directory diff of two Git revisions
+ in one go, unlike "difftool" that compares one file at a time.
+
Foreign Interface
- * Improved handling of views, labels and branches in git-p4 (in contrib).

* "git-p4" (in contrib) suffered from unnecessary merge conflicts when
p4 expanded the embedded $RCS$-like keywords; it can be now told to
* "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
support incremental imports.
+ * "git difftool/mergetool" learned to drive DeltaWalker.
+
Performance
- * During "git upload-pack" in response to "git fetch", unnecessary calls
- to parse_object() have been eliminated, to help performance in

Internal Implementation (please report possible regressions)
* t/Makefile is adjusted to prevent newer versions of GNU make from
running tests in seemingly random order.
+ * The code to check if a path points at a file beyond a symbolic link
+ has been restructured to be thread-safe.
+
+ * When pruning directories that has become empty during "git prune"
+ and "git prune-packed", call closedir() that iterates over a
+ directory before rmdir() it.
+
Also contains minor documentation updates and code clean-ups.
releases are contained in this release (see release notes to them for
details).
- * The code to synthesize the fake ancestor tree used by 3-way merge
- fallback in "git am" was not prepared to read a patch created with
- a non-standard -p<num> value.
- (merge a61ba26 jc/am-3-nonstandard-popt later to maint).
+ * "git fast-import" accepted "ls" command with an empty path by
+ mistake.
+ (merge 178e1de jn/maint-fast-import-empty-ls later to maint).
+
+ * The "remaining" subcommand to "git rerere" was not documented.
+ (merge 3e7a1df ph/rerere-doc later to maint).
+
+ * "git tag -s" honored "gpg.program" configuration variable since
+ 1.7.9, but "git tag -v" and "git verify-tag" didn't.
+ (merge a2c2506 az/verify-tag-use-gpg-config later to maint).
+
+ * When "git config" diagnoses an error in a configuration file and
+ shows the line number for the offending line, it miscounted if the
+ error was at the end of line.
+ (merge 4b34059 ms/maint-config-error-at-eol-linecount later to maint).
+
+ * "configure" script learned to take "--sane-tool-path" from the
+ command line to record SANE_TOOL_PATH (used to avoid broken
+ platform tools in /usr/bin) in config.mak-autogen. This may be useful
+ for people on Solaris who have saner tools outside /usr/xpg[46]/bin.
* "gitweb" used to drop warnings in the log file when "heads" view is
accessed in a repository whose HEAD does not point at a valid
