Git v1.7.10 Release Notes
=========================
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.

UI, Workflows & Features

UI, Workflows & Features
- * Improved handling of views, labels and branches in git-p4 (in contrib).
+ * Teams for localizing the messages from the Porcelain layer of
+ commands are starting to form, thanks to Jiang Xin who volunteered
+ to be the localization coordinator. An initial set of translated
+ messages for simplified chinese is available.
- * Updated command line arguments completion script for zsh (in contrib).
+ * The configuration mechanism learned an "include" facility; an
+ assignment to the include.path pseudo-variable causes the named
+ file to be included in-place when Git looks up configuration
+ variables.
- * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
- support incremental imports.
+ * 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
+ 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

- * The commands in the "git diff" family and "git apply --stat" that
- count the number of files changed and the number of lines
- inserted/deleted have been updated to match the output from
- "diffstat". This also opens the door to i18n this line.
+ 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

+
+ * 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.
+
+ * "git tag --list" can be given "--points-at <object>" to limit its
+ output to those that point at the given object.

+ * "gitweb" learned to read various pieces of information for the
+ repositories lazily, instead of reading everything that could be
+ needed (including the ones that are not necessary for a specific
+ task).
+
+ * 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.

+
+ * Improved handling of views, labels and branches in "git-p4" (in contrib).
+
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when

+ unexpand them.

- * The error message emitted when we see an empty loose object was
- not phrased correctly.
- (merge 33e42de mm/empty-loose-error-message 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).
- * "git commit" refused to create a commit when entries added with
- "add -N" remained in the index, without telling Git what their content
- in the next commit should be. We should have created the commit without
- these paths.
- (merge 3f6d56d jc/maint-commit-ignore-i-t-a later to maint).
+ * The "remaining" subcommand to "git rerere" was not documented.
+ (merge 3e7a1df ph/rerere-doc later to maint).
- * Search box in "gitweb" did not accept non-ASCII characters correctly.
- (merge 84d9e2d jn/gitweb-search-utf-8 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).
- * The code to ask for password did not fall back to the terminal
- input when GIT_ASKPASS is set but does not work (e.g. lack of X
- with GUI askpass helper).
- (merge 84d7273 jk/prompt-fallback-to-tty 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).
- * map_user() was not rewriting its output correctly, which resulted
- in the user visible symptom that "git blame -e" sometimes showed
- excess '>' at the end of email addresses.
- (merge f026358 jc/maint-mailmap-output 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.
- * "checkout -b" did not allow switching out of an unborn branch.
- (merge abe1998 jc/checkout-out-of-unborn later to maint).
+ * "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
+ branch.
