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 behavior (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.
+
+ * When you do not tell which branches and tags to push to the "git
+ push" command in any way, the command used "matching refs" rule to
+ update remote branches and tags with branches and tags with the
+ same name you locally have. In future versions of Git, this will
+ change to push out only your current branch according to either the
+ "upstream" or the "current" rule. Although "upstream" may be more
+ powerful once the user understands Git better, the semantics
+ "current" gives is simpler and easier to understand for beginners
+ and may be a safer and better default option. We haven't decided
+ yet which one to switch to.
+
+
Updates since v1.7.9
--------------------
UI, Workflows & Features
+ * various "gitk" updates.
+ - show the path to the top level directory in the window title
+ - update preference edit dialog
+ - display file list correctly when directories are given on command line
+ - make "git-describe" output in the log message into a clickable link
+ - avoid matching the UNIX timestamp part when searching all fields
+ - give preference to symbolic font names like sans & monospace
+ - allow comparing two commits using a mark
+ - "gitk" honors log.showroot configuration.
+
* 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.
-
- * 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
- unexpand them.
-
- * Some "git-svn" updates.
-
- * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
- support incremental imports.

* The configuration mechanism learned an "include" facility; an
assignment to the include.path pseudo-variable causes the named
* 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
- 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.
+
* "git tag --list" can be given "--points-at <object>" to limit its
output to those that point at the given object.
* "gitweb" allows intermediate entries in the directory hierarchy
- that leads to a projects to be clicked, which in turn shows the
+ that leads to a project to be clicked, which in turn shows the
list of projects inside that directory.
* "gitweb" learned to read various pieces of information for the
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.
+
+ * HTTP transport learned to authenticate with a proxy if needed.
+
+ * 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
+ unexpand them.
+
+ * Some "git-svn" updates.
+
+ * "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
- repositories with excessive number of refs.
+ * Unnecessary calls to parse_object() "git upload-pack" makes in
+ response to "git fetch", have been eliminated, to help performance
+ in repositories with excessive number of refs.
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).
- * "git branch --with $that" assumed incorrectly that the user will never
- ask the question with nonsense value in $that.
- (merge 6c41e97 cn/maint-branch-with-bad later to maint).
-
- * An invalid regular expression pattern given by an end user made
- "gitweb" to return garbled response.
- (merge 36612e4 jn/maint-gitweb-invalid-regexp later to maint).
-
- * "git rev-list --verify-objects -q" omitted the extra verification
- it needs to do over "git rev-list --objects -q" by mistake.
- (merge 9899372 nd/maint-verify-objects later to maint).
-
- * The bulk check-in codepath streamed contents that needs
- smudge/clean filters without running them, instead of punting and
- delegating to the codepath to run filters after slurping everything
- to core.
- (merge 4f22b10 jk/maint-avoid-streaming-filtered-contents later to maint).
-
- * When the filter driver exits before reading the content before the
- main git process writes the contents to be filtered to the pipe to
- it, the latter could be killed with SIGPIPE instead of ignoring
- such an event as an error.
- (merge 6424c2a jb/filter-ignore-sigpipe later to maint).
-
- * When a remote helper exits before reading the blank line from the
- main git process to signal the end of commands, the latter could be
- killed with SIGPIPE. Instead we should ignore such event as a
- non-error.
- (merge c34fe63 sp/smart-http-failure-to-push later to maint).
-
- * "git bundle create" produced a corrupt bundle file upon seeing
- commits with excessively long subject line.
- (merge 8a557bb tr/maint-bundle-long-subject 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.
