[ANNOUNCE] Git v2.8.0-rc4

[Junio C Hamano]

A release candidate Git v2.8.0-rc4 is now available for testing
at the usual places.  It is comprised of 521 non-merge commits
since v2.7.0, contributed by 73 people, 21 of which are new faces.

Relative to v2.8.0-rc3, this reverts the change to the gitignore
mechanism (which also is used in a reverse sense to implement the
sparse checkout feature), as the code seemed to be a bit premature
for general consumption (I haven't queued any replacements yet, but
after 2.8 final I do expect the effort to continue).  Also a new
workaround for GCC 4.2 that dies with "internal compiler error" has
been queued, which would help those who compile with that version of
the compiler (including MacOSX 10.6 and FreeBSD 9.x).

The tarballs are found at:

Git 2.8 Release Notes (draft)
=============================

Backward compatibility note
---------------------------

The rsync:// transport has been removed.


Updates since v2.7
------------------

UI, Workflows & Features

 * It turns out "git clone" over rsync transport has been broken when
   the source repository has packed references for a long time, and
   nobody noticed nor complained about it.

 * "push" learned that its "--delete" option can be shortened to
   "-d", just like "branch --delete" and "branch -d" are the same
   thing.

 * "git blame" learned to produce the progress eye-candy when it takes
   too much time before emitting the first line of the result.

 * "git grep" can now be configured (or told from the command line)
   how many threads to use when searching in the working tree files.

 * Some "git notes" operations, e.g. "git log --notes=<note>", should
   be able to read notes from any tree-ish that is shaped like a notes
   tree, but the notes infrastructure required that the argument must
   be a ref under refs/notes/.  Loosen it to require a valid ref only
   when the operation would update the notes (in which case we must
   have a place to store the updated notes tree, iow, a ref).

 * "git grep" by default does not fall back to its "--no-index"
   behaviour outside a directory under Git's control (otherwise the
   user may by mistake end up running a huge recursive search); with a
   new configuration (set in $HOME/.gitconfig--by definition this
   cannot be set in the config file per project), this safety can be
   disabled.

 * "git pull --rebase" has been extended to allow invoking
   "rebase -i".

 * "git p4" learned to cope with the type of a file getting changed.

 * "git format-patch" learned to notice format.outputDirectory
   configuration variable.  This allows "-o <dir>" option to be
   omitted on the command line if you always use the same directory in
   your workflow.

 * "interpret-trailers" has been taught to optionally update a file in
   place, instead of always writing the result to the standard output.

 * Many commands that read files that are expected to contain text
   that is generated (or can be edited) by the end user to control
   their behaviour (e.g. "git grep -f <filename>") have been updated
   to be more tolerant to lines that are terminated with CRLF (they
   used to treat such a line to contain payload that ends with CR,
   which is usually not what the users expect).

 * "git notes merge" used to limit the source of the merged notes tree
   to somewhere under refs/notes/ hierarchy, which was too limiting
   when inventing a workflow to exchange notes with remote
   repositories using remote-tracking notes trees (located in e.g.
   refs/remote-notes/ or somesuch).

 * "git ls-files" learned a new "--eol" option to help diagnose
   end-of-line problems.

 * "ls-remote" learned an option to show which branch the remote
   repository advertises as its primary by pointing its HEAD at.

 * New http.proxyAuthMethod configuration variable can be used to
   specify what authentication method to use, as a way to work around
   proxies that do not give error response expected by libcurl when
   CURLAUTH_ANY is used.  Also, the codepath for proxy authentication
   has been taught to use credential API to store the authentication
   material in user's keyrings.

 * Update the untracked cache subsystem and change its primary UI from
   "git update-index" to "git config".

 * There were a few "now I am doing this thing" progress messages in
   the TCP connection code that can be triggered by setting a verbose
   option internally in the code, but "git fetch -v" and friends never
   passed the verbose option down to that codepath.

 * Clean/smudge filters defined in a configuration file of lower
   precedence can now be overridden to be a pass-through no-op by
   setting the variable to an empty string.

 * A new "<branch>^{/!-<pattern>}" notation can be used to name a
   commit that is reachable from <branch> that does not match the
   given <pattern>.

 * The "user.useConfigOnly" configuration variable can be used to
   force the user to always set user.email & user.name configuration
   variables, serving as a reminder for those who work on multiple
   projects and do not want to put these in their $HOME/.gitconfig.

 * "git fetch" and friends that make network connections can now be
   told to only use ipv4 (or ipv6).

 * Some authentication methods do not need username or password, but
   libcurl needs some hint that it needs to perform authentication.
   Supplying an empty username and password string is a valid way to
   do so, but you can set the http.[<url>.]emptyAuth configuration
   variable to achieve the same, if you find it cleaner.

 * You can now set http.[<url>.]pinnedpubkey to specify the pinned
   public key when building with recent enough versions of libcURL.

 * The configuration system has been taught to phrase where it found a
   bad configuration variable in a better way in its error messages.
   "git config" learnt a new "--show-origin" option to indicate where
   the values come from.

 * The "credential-cache" daemon process used to run in whatever
   directory it happened to start in, but this made umount(2)ing the
   filesystem that houses the repository harder; now the process
   chdir()s to the directory that house its own socket on startup.

 * When "git submodule update" did not result in fetching the commit
   object in the submodule that is referenced by the superproject, the
   command learned to retry another fetch, specifically asking for
   that commit that may not be connected to the refs it usually
   fetches.

 * "git merge-recursive" learned "--no-renames" option to disable its
   rename detection logic.

 * Across the transition at around Git version 2.0, the user used to
   get a pretty loud warning when running "git push" without setting
   push.default configuration variable.  We no longer warn because the
   transition was completed a long time ago.

 * README has been renamed to README.md and its contents got tweaked
   slightly to make it easier on the eyes.


Performance, Internal Implementation, Development Support etc.

 * Add a framework to spawn a group of processes in parallel, and use
   it to run "git fetch --recurse-submodules" in parallel.

 * A slight update to the Makefile to mark ".PHONY" targets as such
   correctly.

 * In-core storage of the reverse index for .pack files (which lets
   you go from a pack offset to an object name) has been streamlined.

 * d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like
   $GIT_DIR, 2015-06-26) attempted to work around a glitch in alias
   handling by overwriting GIT_WORK_TREE environment variable to
   affect subprocesses when set_git_work_tree() gets called, which
   resulted in a rather unpleasant regression to "clone" and "init".
   Try to address the same issue by always restoring the environment
   and respawning the real underlying command when handling alias.

 * The low-level code that is used to create symbolic references has
   been updated to share more code with the code that deals with
   normal references.

 * strbuf_getline() and friends have been redefined to make it easier
   to identify which callsite of (new) strbuf_getline_lf() should
   allow and silently ignore carriage-return at the end of the line to
   help users on DOSsy systems.

 * "git shortlog" used to accumulate various pieces of information
   regardless of what was asked to be shown in the final output.  It
   has been optimized by noticing what need not to be collected
   (e.g. there is no need to collect the log messages when showing
   only the number of changes).

 * "git checkout $branch" (and other operations that share the same
   underlying machinery) has been optimized.

 * Automated tests in Travis CI environment has been optimized by
   persisting runtime statistics of previous "prove" run, executing
   tests that take longer before other ones; this reduces the total
   wallclock time.

 * Test scripts have been updated to remove assumptions that are not
   portable between Git for POSIX and Git for Windows, or to skip ones
   with expectations that are not satisfiable on Git for Windows.

 * Some calls to strcpy(3) triggers a false warning from static
   analysers that are less intelligent than humans, and reducing the
   number of these false hits helps us notice real issues.  A few
   calls to strcpy(3) in a couple of protrams that are already safe
   has been rewritten to avoid false warnings.

 * The "name_path" API was an attempt to reduce the need to construct
   the full path out of a series of path components while walking a
   tree hierarchy, but over time made less efficient because the path
   needs to be flattened, e.g. to be compared with another path that
   is already flat.  The API has been removed and its users have been
   rewritten to simplify the overall code complexity.

 * Help those who debug http(s) part of the system.
   (merge 0054045 sp/remote-curl-ssl-strerror later to maint).

 * The internal API to interact with "remote.*" configuration
   variables has been streamlined.

 * The ref-filter's format-parsing code has been refactored, in
   preparation for "branch --format" and friends.

 * Traditionally, the tests that try commands that work on the
   contents in the working tree were named with "worktree" in their
   filenames, but with the recent addition of "git worktree"
   subcommand, whose tests are also named similarly, it has become
   harder to tell them apart.  The traditional tests have been renamed
   to use "work-tree" instead in an attempt to differentiate them.
   (merge 5549029 mg/work-tree-tests later to maint).

 * Many codepaths forget to check return value from git_config_set();
   the function is made to die() to make sure we do not proceed when
   setting a configuration variable failed.
   (merge 3d18064 ps/config-error later to maint).

 * Handling of errors while writing into our internal asynchronous
   process has been made more robust, which reduces flakiness in our
   tests.
   (merge 43f3afc jk/epipe-in-async later to maint).

 * There is a new DEVELOPER knob that enables many compiler warning
   options in the Makefile.

 * The way the test scripts configure the Apache web server has been
   updated to work also for Apache 2.4 running on RedHat derived
   distros.

 * Out of maintenance gcc on OSX 10.6 fails to compile the code in
   'master'; work it around by using clang by default on the platform.

 * The "name_path" API was an attempt to reduce the need to construct
   the full path out of a series of path components while walking a
   tree hierarchy, but over time made less efficient because the path
   needs to be flattened, e.g. to be compared with another path that
   is already flat, in many cases.  The API has been removed and its
   users have been rewritten to simplify the overall code complexity.
   This incidentally also closes some heap-corruption holes.

 * Recent versions of GNU grep is pickier than before to decide if a
   file is "binary" and refuse to give line-oriented hits when we
   expect it to, unless explicitly told with "-a" option.  As our
   scripted Porcelains use sane_grep wrapper for line-oriented data,
   even when the line may contain non-ASCII payload we took from
   end-user data, use "grep -a" to implement sane_grep wrapper when
   using an implementation of "grep" that takes the "-a" option.



Also contains various documentation updates and code clean-ups.


Fixes since v2.7
----------------

Unless otherwise noted, all the fixes since v2.7 in the maintenance
track are contained in this release (see the maintenance releases'
notes for details).

 * An earlier change in 2.5.x-era broke users' hooks and aliases by
   exporting GIT_WORK_TREE to point at the root of the working tree,
   interfering when they tried to use a different working tree without
   setting GIT_WORK_TREE environment themselves.

 * The "exclude_list" structure has the usual "alloc, nr" pair of
   fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot
   to reset 'alloc' to 0 when it cleared 'nr' to discard the managed
   array.

 * Paths that have been told the index about with "add -N" are not
   quite yet in the index, but a few commands behaved as if they
   already are in a harmful way.

 * "git send-email" was confused by escaped quotes stored in the alias
   files saved by "mutt", which has been corrected.

 * A few unportable C construct have been spotted by clang compiler
   and have been fixed.

 * The documentation has been updated to hint the connection between
   the '--signoff' option and DCO.

 * "git reflog" incorrectly assumed that all objects that used to be
   at the tip of a ref must be commits, which caused it to segfault.

 * The ignore mechanism saw a few regressions around untracked file
   listing and sparse checkout selection areas in 2.7.0; the change
   that is responsible for the regression has been reverted.

 * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
   (e.g. COMMIT_EDITMSG) that is meant to be left after the command is
   done.  This however did not work well if the repository is set to
   be shared with core.sharedRepository and the umask of the previous
   user is tighter.  They have been made to work better by calling
   unlink(2) and retrying after fopen(3) fails with EPERM.

 * Asking gitweb for a nonexistent commit left a warning in the server
   log.

   Somebody may want to follow this up with an additional test, perhaps?
   IIRC, we do test that no Perl warnings are given to the server log,
   so this should have been caught if our test coverage were good.

 * "git rebase", unlike all other callers of "gc --auto", did not
   ignore the exit code from "gc --auto".

 * Many codepaths that run "gc --auto" before exiting kept packfiles
   mapped and left the file descriptors to them open, which was not
   friendly to systems that cannot remove files that are open.  They
   now close the packs before doing so.

 * A recent optimization to filter-branch in v2.7.0 introduced a
   regression when --prune-empty filter is used, which has been
   corrected.

 * The description for SANITY prerequisite the test suite uses has
   been clarified both in the comment and in the implementation.

 * "git tag" started listing a tag "foo" as "tags/foo" when a branch
   named "foo" exists in the same repository; remove this unnecessary
   disambiguation, which is a regression introduced in v2.7.0.

 * The way "git svn" uses auth parameter was broken by Subversion
   1.9.0 and later.

 * The "split" subcommand of "git subtree" (in contrib/) incorrectly
   skipped merges when it shouldn't, which was corrected.

 * A few options of "git diff" did not work well when the command was
   run from a subdirectory.

 * The command line completion learned a handful of additional options
   and command specific syntax.

 * dirname() emulation has been added, as Msys2 lacks it.

 * The underlying machinery used by "ls-files -o" and other commands
   has been taught not to create empty submodule ref cache for a
   directory that is not a submodule.  This removes a ton of wasted
   CPU cycles.

 * "git worktree" had a broken code that attempted to auto-fix
   possible inconsistency that results from end-users moving a
   worktree to different places without telling Git (the original
   repository needs to maintain backpointers to its worktrees, but
   "mv" run by end-users who are not familiar with that fact will
   obviously not adjust them), which actually made things worse
   when triggered.

 * The low-level merge machinery has been taught to use CRLF line
   termination when inserting conflict markers to merged contents that
   are themselves CRLF line-terminated.

 * "git push --force-with-lease" has been taught to report if the push
   needed to force (or fast-forwarded).

 * The emulated "yes" command used in our test scripts has been
   tweaked not to spend too much time generating unnecessary output
   that is not used, to help those who test on Windows where it would
   not stop until it fills the pipe buffer due to lack of SIGPIPE.

 * The documentation for "git clean" has been corrected; it mentioned
   that .git/modules/* are removed by giving two "-f", which has never
   been the case.

 * The vimdiff backend for "git mergetool" has been tweaked to arrange
   and number buffers in the order that would match the expectation of
   majority of people who read left to right, then top down and assign
   buffers 1 2 3 4 "mentally" to local base remote merge windows based
   on that order.

 * "git show 'HEAD:Foo[BAR]Baz'" did not interpret the argument as a
   rev, i.e. the object named by the the pathname with wildcard
   characters in a tree object.
   (merge aac4fac nd/dwim-wildcards-as-pathspecs later to maint).

 * "git rev-parse --git-common-dir" used in the worktree feature
   misbehaved when run from a subdirectory.
   (merge 17f1365 nd/git-common-dir-fix later to maint).

 * "git worktree add -B <branchname>" did not work.

 * The "v(iew)" subcommand of the interactive "git am -i" command was
   broken in 2.6.0 timeframe when the command was rewritten in C.
   (merge 708b8cc jc/am-i-v-fix later to maint).

 * "git merge-tree" used to mishandle "both sides added" conflict with
   its own "create a fake ancestor file that has the common parts of
   what both sides have added and do a 3-way merge" logic; this has
   been updated to use the usual "3-way merge with an empty blob as
   the fake common ancestor file" approach used in the rest of the
   system.
   (merge 907681e jk/no-diff-emit-common later to maint).

 * The memory ownership rule of fill_textconv() API, which was a bit
   tricky, has been documented a bit better.
   (merge a64e6a4 jk/more-comments-on-textconv later to maint).

 * Update various codepaths to avoid manually-counted malloc().
   (merge 08c95df jk/tighten-alloc later to maint).

 * The documentation did not clearly state that the 'simple' mode is
   now the default for "git push" when push.default configuration is
   not set.
   (merge f6b1fb3 mm/push-simple-doc later to maint).

 * Recent versions of GNU grep are pickier when their input contains
   arbitrary binary data, which some of our tests uses.  Rewrite the
   tests to sidestep the problem.
   (merge 3b1442d jk/grep-binary-workaround-in-test later to maint).

 * A helper function "git submodule" uses since v2.7.0 to list the
   modules that match the pathspec argument given to its subcommands
   (e.g. "submodule add <repo> <path>") has been fixed.
   (merge 2b56bb7 sb/submodule-module-list-fix later to maint).

 * "git config section.var value" to set a value in per-repository
   configuration file failed when it was run outside any repository,
   but didn't say the reason correctly.
   (merge 638fa62 js/config-set-in-non-repository later to maint).

 * The code to read the pack data using the offsets stored in the pack
   idx file has been made more carefully check the validity of the
   data in the idx.
   (merge 7465feb jk/pack-idx-corruption-safety later to maint).

 * Other minor clean-ups and documentation updates
   (merge f459823 ak/extract-argv0-last-dir-sep later to maint).
   (merge 63ca1c0 ak/git-strip-extension-from-dashed-command later to maint).
   (merge 4867f11 ps/plug-xdl-merge-leak later to maint).
   (merge 4938686 dt/initial-ref-xn-commit-doc later to maint).
   (merge 9537f21 ma/update-hooks-sample-typofix later to maint).
