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.
+
+
Updates since v1.7.9
--------------------
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.
- * "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
+ file to be included in-place when Git looks up configuration
+ variables.
+
+ * 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".
+
+ * 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.
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" learned to pay attention to the "-i" option and can
+ find patch hunks that introduce or remove a string that matches the
+ given pattern ignoring the case.
+
* "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
- can export MERGE_AUTOEDIT=no to retain the historical behaviour.
+ can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior.
+ Both "git merge" and "git pull" can be given --no-edit from the
+ command line to accept the auto-generated merge message.
+
+ * The advise 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".
+
+ * "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
list of projects inside that directory.
+ * "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.
+
+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 respose 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
+Internal Implementation (please report possible regressions)
* Recursive call chains in "git index-pack" to deal with long delta
chains have been flattened, to reduce the stack footprint.
- * Use of add_extra_ref() API is slowly getting removed, to make it
- possible to cleanly restructure the overall refs API.
+ * Use of add_extra_ref() API is now gone, to make it possible to
+ cleanly restructure the overall refs API.
+
+ * The command line parser of "git pack-objects" now uses parse-options
+ API.
* The test suite supports the new "test_pause" helper function.
+ * Parallel to the test suite, there is a beginning of performance
+ benchmarking framework.
+
* 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.
+
Also contains minor documentation updates and code clean-ups.
releases are contained in this release (see release notes to them for
details).
- * "add -e" learned not to show a diff for an otherwise unmodified
- submodule that only has uncommitted local changes in the patch
- prepared by for the user to edit.
- (merge 701825d js/add-e-submodule-fix later to maint).
-
- * "rebase" and "commit --amend" failed to work on commits with ancient
- timestamps near year 1970.
- (merge 2c733fb jc/parse-date-raw later to maint).
+ * "git bundle" did not record boundary commits correctly when there
+ are many of them.
+ (merge efe4be1 tr/maint-bundle-boundary later to maint).
- * "git merge --ff-only $tag" failed because it cannot record the
- required mergetag without creating a merge, but this is so common
- operation for branch that is used _only_ to follow the upstream, so
- it is allowed to fast-forward without recording the mergetag.
- (merge b5c9f1c jc/merge-ff-only-stronger-than-signed-merge later to maint).
+ * "git diff-index" and its friends at the plumbing level showed the
+ "diff --git" header and nothing else for a path whose cached stat
+ info is dirty without actual difference when asked to produce a
+ patch. This was a longstanding bug that we could have fixed long
+ time ago.
+ (merge b3f01ff jc/maint-diff-patch-header later to maint).
- * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
- (merge c2d17ba jc/branch-desc-typoavoidance later to maint).
+ * 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).
- * rpmbuild noticed an unpackaged but installed *.mo file and failed.
- (merge 3a9f58c jn/rpm-spec 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.
