UI, Workflows & Features
+ * A new mode for push, "simple", which is a cross between "current"
+ and "upstream", has been introduced. "git push" without any refspec
+ will push the current branch out to the same name at the remote
+ repository only when it is set to track the branch with the same
+ name over there. The plan is to make this mode the new default
+ value when push.default is not configured.
+
* A third-party tool "git subtree" is distributed in contrib/
+ * Error messages given when @{u} is used for a branch without its
+ upstream configured have been clatified.
+
* Even with "-q"uiet option, "checkout" used to report setting up
tracking. Also "branch" learned the "-q"uiet option to squelch
informational message.
variables with REMOTE_USER and REMOTE_ADDR, but these variables are
now preserved when set.
+ * "include.path" mechanism of the configuration files learned to
+ understand "~/path" and "~user/path".
+
* "git am" learned the "--include" option, which is an opposite of
existing the "--exclude" option.
needed such treatment are now reported to the end user, so that the
result in them can be eyeballed with extra care.
+ * The output from "diff/log --stat" used to always allocate 4 columns
+ to show the number of modified lines, but not anymore.
+
* The "fmt-merge-msg" command learns to list the primary contributors
involved in the side topic you are merging.
* The cases "git push" fails due to non-ff can be broken into three
categories; each case is given a separate advise message.
+ * "git rebase" learned to optionally keep commits that do not
+ introduce any change in the original history.
+
+ * "git push --recurse-submodules" learned to optionally look into the
+ histories of submodules bound to the superproject and push them
+ out.
+
* A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
based on the commit date.
+ * "gitweb" learned to highlight the patch it outputs even more.
+
Foreign Interface
+ * "git svn" used to die with unwanted SIGPIPE when talking with HTTP
+ server that uses keep-alive.
-Performance
+ * "git svn" learned to use platform specific authentication
+ providers, e.g. gnome-keyring, kwallet, etc.
+ * "git p4" has been moved out of contrib/ area and has seen more work
+ on importing labels as tags from (and exporting tags as labels to)
+ p4.
-Internal Implementation (please report possible regressions)
+Performance and Internal Implementation (please report possible regressions)
+
+ * An experimental "version 4" format of the index file has been
+ introduced to reduce on-disk footprint and I/O overhead.
+
+ * The code to compute hash values for lines used by the internal diff
+ engine was optimized on little-endian machines, using the same
+ trick the kernel folks came up with.
+
+ * "git apply" had some memory leaks plugged.
+
+ * "git repack" used to write out unreachable objects as loose objects
+ when repacking, even if such loose objects will immediately pruned
+ due to its age.
+
+ * Setting up a revision traversal with many starting points was
+ inefficient as these were placed in a date-order priority queue
+ one-by-one. Now they are collected in the queue unordered first,
+ and sorted immediately before getting used.
+
+ * "git rev-parse --show-prefix" used to emit nothing when run at the
+ top-level of the working tree, but now it gives a blank line.
* Minor memory leak during unpack_trees (hence "merge" and "checkout"
to check out another branch) has been plugged.
systems, run-command API now uses SHELL_PATH, not /bin/sh, when
spawning an external command (not applicable to Windows port).
+ * The API to iterate over refs/ hierarchy has been tweaked to allow
+ walking only a subset of it more efficiently.
+
Also contains minor documentation updates and code clean-ups.
releases are contained in this release (see release notes to them for
details).
- * When PATH contains an unreadable directory, alias expansion code
- did not kick in, and failed with an error that said "git-subcmd"
- was not found.
- (merge 38f865c jk/run-command-eacces later to maint).
-
- * The 'push to upstream' implementation was broken in some corner
- cases. "git push $there" without refspec, when the current branch
- is set to push to a remote different from $there, used to push to
- $there using the upstream information to a remote unreleated to
- $there.
- (merge 135dade jc/push-upstream-sanity later to maint).
-
- * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
- working trees of independent git repositories that exist in the
- current project working tree from getting removed, but the
- protection applied only to such working trees that are at the
- top-level of the current project by mistake.
- (merge ae2f203 jc/maint-clean-nested-worktree-in-subdir later to maint).
-
- * Rename detection logic used to match two empty files as renames
- during merge-recursive, leading unnatural mismerges.
- (merge 4f7cb99 jk/diff-no-rename-empty later to maint).
-
- * An age-old corner case bug in combine diff (only triggered with -U0
- and the hunk at the beginning of the file needs to be shown) has
- been fixed.
- (merge e5e9b56 rs/combine-diff-zero-context-at-the-beginning later to maint).
-
- * When "git commit --template F" errors out because the user did not
- touch the message, it claimed that it aborts due to "empty
- message", which was utterly wrong.
- (merge 1f08c2c jc/commit-unedited-template later to maint).
-
- * "git add -p" is not designed to deal with unmerged paths but did
- not exclude them and tried to apply funny patches only to fail.
- (merge 4066bd6 jk/add-p-skip-conflicts later to maint).
-
- * "git commit --author=$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).
+ * When using a Perl script on a system where "perl" found on user's
+ $PATH could be ancient or otherwise broken, we allow builders to
+ specify the path to a good copy of Perl with $PERL_PATH. The
+ gitweb test forgot to use that Perl when running its test.
+ (merge 0754e08 jk/maint-gitweb-test-use-sane-perl later to maint).
+
+ * A contrib script "rerere-train" did not work out of the box unless
+ user futzed with her $PATH.
+ (merge 53876fc jc/rerere-train later to maint).
+
+ * "log --graph" was not very friendly with "--stat" option and its
+ output had line breaks at wrong places.
+ (merge bafa16e lp/diffstat-with-graph later to maint).
+
+ * "git config --rename-section" to rename an existing section into a
+ bogus one did not check the new name.
+ (merge 94a35b1 jk/maint-config-bogus-section later to maint).
+
+ * The test scaffolding for git-daemon was flaky.
+ (merge 46e3581 js/daemon-test-race-fix later to maint).
+
+ * The test scaffolding for fast-import was flaky.
+ (merge 7fb8e16 pw/t5800-import-race-fix later to maint).
+
+ * Octopus merge strategy did not reduce heads that are recorded in the
+ final commit correctly.
+ (merge 5802f81 jc/merge-reduce-parents-early later to maint).
+
+ * In the older days, the header "Conflicts:" in "cherry-pick" and
+ "merge" was separated by a blank line from the list of paths that
+ follow for readability, but when "merge" was rewritten in C, we lost
+ it by mistake. Remove the newline from "cherry-pick" to make them
+ match again.
+ (merge 5112068 rt/cherry-revert-conflict-summary later to maint).
+
+ * The filesystem boundary was not correctly reported when .git
+ directory discovery stopped at a mount point.
+ (merge 2565b43 cb/maint-report-mount-point-correctly-in-setup later to maint).
+
+ * The command line parser choked "git cherry-pick $name" when $name
+ can be both revision name and a pathname, even though $name can
+ never be a path in the context of the command.
+ (merge 6d5b93f cb/cherry-pick-rev-path-confusion later to maint).
+
+ * HTTP transport that requires authentication did not work correctly
+ when multiple connections are used simultaneously.
+ (merge 6f4c347 cb/http-multi-curl-auth later to maint).
+
+ * The i18n of error message "git stash save" was not properly done.
+ (merge ed3c400 rl/maint-stash-i18n-save-error later to maint).
+
+ * The report from "git fetch" said "new branch" even for a non branch
+ ref.
+ (merge 0997ada mb/fetch-call-a-non-branch-a-ref later to maint).
+
+ * The "diff --no-index" codepath used limited-length buffers, risking
+ pathnames getting truncated. Update it to use the strbuf API.
+ (merge 875b91b jm/maint-strncpy-diff-no-index later to maint).
