+GIT v1.6.1.1 Release Notes
+==========================
+
+Fixes since v1.6.1
+------------------
+
+* "git add frotz/nitfol" when "frotz" is a submodule should have errored
+ out, but it didn't.
+
+* "git apply" took file modes from the patch text and updated the mode
+ bits of the target tree even when the patch was not about mode changes.
+
+* "git bisect view" on Cygwin did not launch gitk
+
+* "git checkout $tree" did not trigger an error.
+
+* "git commit" tried to remove COMMIT_EDITMSG from the work tree by mistake.
+
+* "git describe --all" complained when a commit is described with a tag,
+ which was nonsense.
+
+* "git diff --no-index --" did not trigger no-index (aka "use git-diff as
+ a replacement of diff on untracked files") behaviour.
+
+* "git format-patch -1 HEAD" on a root commit failed to produce patch
+ text.
+
+* "git fsck branch" did not work as advertised; instead it behaved the same
+ way as "git fsck".
+
+* "git log --pretty=format:%s" did not handle a multi-line subject the
+ same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
+
+* "git daemon", and "git merge-file" are more careful when freopen fails
+ and barf, instead of going on and writing to unopened filehandle.
+
+* "git http-push" did not like some RFC 4918 compliant DAV server
+ responses.
+
+* "git merge -s recursive" mistakenly overwritten an untracked file in the
+ work tree upon delete/modify conflict.
+
+* "git merge -s recursive" didn't leave the index unmerged for entries with
+ rename/delete conflictd.
+
+* "git merge -s recursive" clobbered untracked files in the work tree.
+
+* "git mv -k" with more than one errorneous paths misbehaved.
+
+* "git read-tree -m -u" hence branch switching incorrectly lost a
+ subdirectory in rare cases.
+
+* "git rebase -i" issued an unnecessary error message upon a user error of
+ marking the first commit to be "squash"ed.
+
+* "git shortlog" did not format a commit message with multi-line
+ subject correctly.
+
+Many documentation updates.

+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output. This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command. We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+ can run gitk from its blame view.
+
+* Various git-gui updates including updated translations.
+
+* Various gitweb updates from repo.or.cz installation.
+
+* Updates to emacs bindings.
+
+(portability)
+
+* A few test scripts used nonportable "grep" that did not work well on
+ some platforms, e.g. Solaris.
+
+* Sample pre-auto-gc script has OS X support.
+
+* Makefile has support for (ancient) FreeBSD 4.9.
+
+(performance)
+
+* Many operations that are lstat(3) heavy can be told to pre-execute
+ necessary lstat(3) in parallel before their main operations, which
+ potentially gives much improved performance for cold-cache cases or in
+ environments with weak metadata caching (e.g. NFS).
+
+* The underlying diff machinery to produce textual output has been
+ optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+ can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+ refs has been optimized.
+
+* Cygwin port uses native stat/lstat implementations when applicable,
+ which leads to improved performance.
+
+* "git push" pays attention to alternate repositories to avoid sending
+ unnecessary objects.
+
+* "git svn" can rebuild an out-of-date rev_map file.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+ you might have meant to say. help.autocorrect configuration can be set
+ to a non-zero value to accept the suggestion when git can uniquely
+ guess.
+
+* The packfile machinery hopefully is more robust when dealing with
+ corrupt packs if redundant objects involved in the corruption are
+ available elsewhere.
+
+* "git add -N path..." adds the named paths as an empty blob, so that
+ subsequent "git diff" will show a diff as if they are creation events.
+
+* "git add" gained a built-in synonym for people who want to say "stage
+ changes" instead of "add contents to the staging area" which amounts
+ to the same thing.
+
+* "git apply" learned --include=paths option, similar to the existing
+ --exclude=paths option.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+ merge base first when good is not a strict ancestor of bad.
+
+* "git bisect skip" can take a range of commits.
+
+* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
+ by default.
+
+* "git check-attr --stdin" can check attributes for multiple paths.
+
+* "git checkout --track origin/hack" used to be a syntax error. It now
+ DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+ said "git checkout --track -b hack origin/hack".
+
+* "git checkout --ours/--theirs" can be used to check out one side of a
+ conflicting merge during conflict resolution.
+
+* "git checkout -m" can be used to recreate the initial conflicted state
+ during conflict resolution.
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git clone" learned to be verbose with -v
+
+* "git commit --author=$name" can look up author name from existing
+ commits.
+
+* output from "git commit" has been reworded in a more concise and yet
+ more informative way.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+ their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git daemon" exports REMOTE_ADDR to record client address, so that
+ spawned programs can act differently on it.
+
+* "git describe --tags" favours closer lightweight tags than farther
+ annotated tags now.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+ configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python,
+ HTML and ObjC contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+ being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git diff" learned --dirstat-by-file to count changed files, not number
+ of lines, when summarizing the global picture.
+
+* "git diff" learned "textconv" filters --- a binary or hard-to-read
+ contents can be munged into human readable form and the difference
+ between the results of the conversion can be viewed (obviously this
+ cannot produce a patch that can be applied, so this is disabled in
+ format-patch among other things).
+
+* "--cached" option to "git diff has an easier to remember synonym "--staged",
+ to ask "what is the difference between the given commit and the
+ contents staged in the index?"
+
+* "git for-each-ref" learned "refname:short" token that gives an
+ unambiguously abbreviated refname.
+
+* Auto-numbering of the subject lines is the default for "git
+ format-patch" now.
+
+* "git grep" learned to accept -z similar to GNU grep.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+ using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+ completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+ status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+ "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log" learned "--source" to show what ref each commit was reached
+ from.
+
+* "git log" also learned "--simplify-by-decoration" to show the
+ birds-eye-view of the topology of the history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+ names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+ noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+ command "git-merge-$strategy" on your $PATH.
+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
+ "-q"uietly.
+
+* "git push" can be told to reject deletion of refs with receive.denyDeletes
+ configuration.
+
+* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
+
+* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+ refs/heads/branch".
+
+* "git remote show $remote" lists remote branches one-per-line now.
+
+* "git send-email" can be given revision range instead of files and
+ maildirs on the command line, and automatically runs format-patch to
+ generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+ out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+ recorded in submodule directories from the toplevel .gitmodules file.
+
+* "git svn branch" can create new branches on the other end.
+
+* "gitweb" can use more saner PATH_INFO based URL.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+ correct gitattributes processing can be done while hashing contents
+ stored in a temporary file.
+
+* various callers of git-merge-recursive avoid forking it as an external
+ process.
+
+* Git class defined in "Git.pm" can be subclasses a bit more easily.
+
+* We used to link GNU regex library as a compatibility layer for some
+ platforms, but it turns out it is not necessary on most of them.
+
+* Some path handling routines used fixed number of buffers used alternately
+ but depending on the call depth, this arrangement led to hard to track
+ bugs. This issue is being addressed.
+
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* Porcelains implemented as shell scripts were utterly confused when you
+ entered to a subdirectory of a work tree from sideways, following a
+ symbolic link (this may need to be backported to older releases later).
+
+* Tracking symbolic links would work better on filesystems whose lstat()
+ returns incorrect st_size value for them.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+ is a tracked symlink that points at a directory D that has a path F in
+ it (we still need to fix a similar nonsense when S is a submodule and F
+ is a path in it).
+
+* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
+ --3way options given from the command line initially.
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+ but we dropped support for such a use case long time ago. This has
+ been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git http-push" did not understand URI scheme other than opaquelocktoken
+ when acquiring a lock from the server (this may need to be backported to
+ older releases later).
+
+* After "git rebase -p" stopped with conflicts while replaying a merge,
+ "git rebase --continue" did not work (may need to be backported to older
+ releases).
+
+* "git revert" records relative to which parent a revert was made when
+ reverting a merge. Together with new documentation that explains issues
+ around reverting a merge and merging from the updated branch later, this
+ hopefully will reduce user confusion (this may need to be backported to
+ older releases later).
+
+* "git rm --cached" used to allow an empty blob that was added earlier to
+ be removed without --force, even when the file in the work tree has
+ since been modified.
+
+* "git push --tags --all $there" failed with generic usage message without
+ telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+ timestamp part, exposing internal implementation detail. Also these did
+ not work with --fixed-strings match at all.
+
+* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
+ correctly.

DESCRIPTION
-----------
-'git-merge-base' finds as good a common ancestor as possible between
-the two commits. That is, given two commits A and B, `git merge-base A
-B` will output a commit which is reachable from both A and B through
-the parent relationship.
+'git-merge-base' finds best common ancestor(s) between two commits to use
+in a three-way merge. One common ancestor is 'better' than another common
+ancestor if the latter is an ancestor of the former. A common ancestor
+that does not have any better common ancestor is a 'best common
+ancestor', i.e. a 'merge base'. Note that there can be more than one
+merge base for a pair of commits.
-Given a selection of equally good common ancestors it should not be
-relied on to decide in any particular way.
-
-The 'git-merge-base' algorithm is still in flux - use the source...
+Among the two commits to compute the merge base from, one is specified by
+the first commit argument on the command line; the other commit is a
+(possibly hypothetical) commit that is a merge across all the remaining
+commits on the command line. As the most common special case, specifying only
+two commits on the command line means computing the merge base between
+the given two commits.
OPTIONS
-------
--all::
- Output all common ancestors for the two commits instead of
- just one.
+ Output all merge bases for the commits, instead of just one.
+
+DISCUSSION
+----------
+
+Given two commits 'A' and 'B', `git merge-base A B` will output a commit
+which is reachable from both 'A' and 'B' through the parent relationship.
+
+For example, with this topology:
+
+ o---o---o---B
+ /
+ ---o---1---o---o---o---A
+
+the merge base between 'A' and 'B' is '1'.
+
+Given three commits 'A', 'B' and 'C', `git merge-base A B C` will compute the
+merge base between 'A' and a hypothetical commit 'M', which is a merge
+between 'B' and 'C'. For example, with this topology:
+
+ o---o---o---o---C
+ /
+ / o---o---o---B
+ / /
+ ---2---1---o---o---o---A
+
+the result of `git merge-base A B C` is '1'. This is because the
+equivalent topology with a merge commit 'M' between 'B' and 'C' is:
+
+
+ o---o---o---o---o
+ / \
+ / o---o---o---o---M
+ / /
+ ---2---1---o---o---o---A
+
+and the result of `git merge-base A M` is '1'. Commit '2' is also a
+common ancestor between 'A' and 'M', but '1' is a better common ancestor,
+because '2' is an ancestor of '1'. Hence, '2' is not a merge base.
+
+When the history involves criss-cross merges, there can be more than one
+'best' common ancestor for two commits. For example, with this topology:
+
+ ---1---o---A
+ \ /
+ X
+ / \
+ ---2---o---o---B
+
+both '1' and '2' are merge-bases of A and B. Neither one is better than
+the other (both are 'best' merge bases). When the `--all` option is not given,
+it is unspecified which best one is output.

+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge. Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim. When both sides made changes to the same area,
+however, git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, git uses the same style as that is used by "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area where a pair of conflicting changes happened is marked with markers
+"`<<<<<<<`", "`=======`", and "`>>>>>>>`". The part before the "`=======`"
+is typically your side, and the part afterwards is typically their side.
+
+The default format does not show what the original said in the conflicting
+area. You cannot tell how many lines are deleted and replaced with
+Barbie's remark on your side. The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictstyle"
+configuration variable to "diff3". In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+|||||||
+Conflict resolution is hard.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+In addition to the "`<<<<<<<`", "`=======`", and "`>>>>>>>`" markers, it uses
+another "`|||||||`" marker that is followed by the original text. You can
+tell that the original just stated a fact, and your side simply gave in to
+that statement and gave up, while the other side tried to have a more
+positive attitude. You can sometimes come up with a better resolution by
+viewing the original.
+
+
+HOW TO RESOLVE CONFLICTS
+------------------------
+
After seeing a conflict, you can do two things:
- * Decide not to merge. The only clean-up you need are to reset
+ * Decide not to merge. The only clean-ups you need are to reset
the index file to the `HEAD` commit to reverse 2. and to clean
up working tree changes made by 2. and 3.; 'git-reset --hard' can
be used for this.
- * Resolve the conflicts. `git diff` would report only the
- conflicting paths because of the above 2. and 3.
- Edit the working tree files into a desirable shape
- ('git mergetool' can ease this task), 'git-add' or 'git-rm'
- them, to make the index file contain what the merge result
- should be, and run 'git-commit' to commit the result.
+ * Resolve the conflicts. Git will mark the conflicts in
+ the working tree. Edit the files into shape and
+ 'git-add' them to the index. Use 'git-commit' to seal the deal.
+

+RECOVERING FROM UPSTREAM REBASE
+-------------------------------
+
+Rebasing (or any other form of rewriting) a branch that others have
+based work on is a bad idea: anyone downstream of it is forced to
+manually fix their history. This section explains how to do the fix
+from the downstream's point of view. The real fix, however, would be
+to avoid rebasing the upstream in the first place.
+
+To illustrate, suppose you are in a situation where someone develops a
+'subsystem' branch, and you are working on a 'topic' that is dependent
+on this 'subsystem'. You might end up with a history like the
+following:
+
+------------
+ o---o---o---o---o---o---o---o---o master
+ \
+ o---o---o---o---o subsystem
+ \
+ *---*---* topic
+------------
+
+If 'subsystem' is rebased against 'master', the following happens:
+
+------------
+ o---o---o---o---o---o---o---o master
+ \ \
+ o---o---o---o---o o'--o'--o'--o'--o' subsystem
+ \
+ *---*---* topic
+------------
+
+If you now continue development as usual, and eventually merge 'topic'
+to 'subsystem', the commits from 'subsystem' will remain duplicated forever:
+
+------------
+ o---o---o---o---o---o---o---o master
+ \ \
+ o---o---o---o---o o'--o'--o'--o'--o'--M subsystem
+ \ /
+ *---*---*-..........-*--* topic
+------------
+
+Such duplicates are generally frowned upon because they clutter up
+history, making it harder to follow. To clean things up, you need to
+transplant the commits on 'topic' to the new 'subsystem' tip, i.e.,
+rebase 'topic'. This becomes a ripple effect: anyone downstream from
+'topic' is forced to rebase too, and so on!
+
+There are two kinds of fixes, discussed in the following subsections:
+
+Easy case: The changes are literally the same.::
+
+ This happens if the 'subsystem' rebase was a simple rebase and
+ had no conflicts.
+
+Hard case: The changes are not the same.::
+
+ This happens if the 'subsystem' rebase had conflicts, or used
+ `\--interactive` to omit, edit, or squash commits; or if the
+ upstream used one of `commit \--amend`, `reset`, or
+ `filter-branch`.
+
+
+The easy case
+~~~~~~~~~~~~~
+
+Only works if the changes (patch IDs based on the diff contents) on
+'subsystem' are literally the same before and after the rebase
+'subsystem' did.
+
+In that case, the fix is easy because 'git-rebase' knows to skip
+changes that are already present in the new upstream. So if you say
+(assuming you're on 'topic')
+------------
+ $ git rebase subsystem
+------------
+you will end up with the fixed history
+------------
+ o---o---o---o---o---o---o---o master
+ \
+ o'--o'--o'--o'--o' subsystem
+ \
+ *---*---* topic
+------------
+
+
+The hard case
+~~~~~~~~~~~~~
+
+Things get more complicated if the 'subsystem' changes do not exactly
+correspond to the ones before the rebase.
+
+NOTE: While an "easy case recovery" sometimes appears to be successful
+ even in the hard case, it may have unintended consequences. For
+ example, a commit that was removed via `git rebase
+ \--interactive` will be **resurrected**!
+
+The idea is to manually tell 'git-rebase' "where the old 'subsystem'
+ended and your 'topic' began", that is, what the old merge-base
+between them was. You will have to find a way to name the last commit
+of the old 'subsystem', for example:
+
+* With the 'subsystem' reflog: after 'git-fetch', the old tip of
+ 'subsystem' is at `subsystem@\{1}`. Subsequent fetches will
+ increase the number. (See linkgit:git-reflog[1].)
+
+* Relative to the tip of 'topic': knowing that your 'topic' has three
+ commits, the old tip of 'subsystem' must be `topic~3`.
+
+You can then transplant the old `subsystem..topic` to the new tip by
+saying (for the reflog case, and assuming you are on 'topic' already):
+------------
+ $ git rebase --onto subsystem subsystem@{1}
+------------
+
+The ripple effect of a "hard case" recovery is especially bad:
+'everyone' downstream from 'topic' will now have to perform a "hard
+case" recovery too!

+If a file `.mailmap` exists at the toplevel of the repository,
+it is used to map an author email address to a canonical real name. This
+can be used to coalesce together commits by the same person where their
+name was spelled differently (whether with the same email address or
+not).
+
+Each line in the file consists, in this order, of the canonical real name
+of an author, whitespace, and an email address (enclosed by '<' and '>')
+to map to the name. Use hash '#' for comments, either on their own line,
+or after the email address.
+
+A canonical name may appear in more than one line, associated with
+different email addresses, but it doesn't make sense for a given address
+to appear more than once (if that happens, a later line overrides the
+earlier ones).
+
+So, for example, if your history contains commits by two authors, Jane
+and Joe, whose names appear in the repository under several forms:
+
+------------
+Joe Developer <joe@example.com>
+Joe R. Developer <joe@example.com>
+Jane Doe <jane@example.com>
+Jane Doe <jane@laptop.(none)>
+Jane D. <jane@desktop.(none)>
+------------
+
+Then, supposing Joe wants his middle name initial used, and Jane prefers
+her family name fully spelled out, a proper `.mailmap` file would look like:
------------
-# Keep alphabetized
-Adam Morrow <adam@localhost.localdomain>
-Eve Jones <eve@laptop.(none)>
+# Note how we don't need an entry for <jane@laptop.(none)>, because the
+# real name of that author is correct already, and coalesced directly.

+Performing text diffs of binary files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Sometimes it is desirable to see the diff of a text-converted
+version of some binary files. For example, a word processor
+document can be converted to an ASCII text representation, and
+the diff of the text shown. Even though this conversion loses
+some information, the resulting diff is useful for human
+viewing (but cannot be applied directly).
+
+The `textconv` config option is used to define a program for
+performing such a conversion. The program should take a single
+argument, the name of a file to convert, and produce the
+resulting text on stdout.
+
+For example, to show the diff of the exif information of a
+file instead of the binary information (assuming you have the
+exif tool installed):
+
+------------------------
+[diff "jpg"]
+ textconv = exif
+------------------------
+
+NOTE: The text conversion is generally a one-way conversion;
+in this example, we lose the actual image contents and focus
+just on the text data. This means that diffs generated by
+textconv are _not_ suitable for applying. For this reason,
+only `git diff` and the `git log` family of commands (i.e.,
+log, whatchanged, show) will perform text conversion. `git
+format-patch` will never generate this output. If you want to
+send somebody a text-converted diff of a binary file (e.g.,
+because it quickly conveys the changes you have made), you
+should generate it separately and send it as a comment _in
+addition to_ the usual binary diff that you might send.

+===============
+
+NAME
+----
+gitworkflows - An overview of recommended workflows with git
+
+SYNOPSIS
+--------
+git *
+
+
+DESCRIPTION
+-----------
+
+This document attempts to write down and motivate some of the workflow
+elements used for `git.git` itself. Many ideas apply in general,
+though the full workflow is rarely required for smaller projects with
+fewer people involved.
+
+We formulate a set of 'rules' for quick reference, while the prose
+tries to motivate each of them. Do not always take them literally;
+you should value good reasons for your actions higher than manpages
+such as this one.
+
+
+SEPARATE CHANGES
+----------------
+
+As a general rule, you should try to split your changes into small
+logical steps, and commit each of them. They should be consistent,
+working independently of any later commits, pass the test suite, etc.
+This makes the review process much easier, and the history much more
+useful for later inspection and analysis, for example with
+linkgit:git-blame[1] and linkgit:git-bisect[1].
+
+To achieve this, try to split your work into small steps from the very
+beginning. It is always easier to squash a few commits together than
+to split one big commit into several. Don't be afraid of making too
+small or imperfect steps along the way. You can always go back later
+and edit the commits with `git rebase \--interactive` before you
+publish them. You can use `git stash save \--keep-index` to run the
+test suite independent of other uncommitted changes; see the EXAMPLES
+section of linkgit:git-stash[1].
+
+
+MANAGING BRANCHES
+-----------------
+
+There are two main tools that can be used to include changes from one
+branch on another: linkgit:git-merge[1] and
+linkgit:git-cherry-pick[1].
+
+Merges have many advantages, so we try to solve as many problems as
+possible with merges alone. Cherry-picking is still occasionally
+useful; see "Merging upwards" below for an example.
+
+Most importantly, merging works at the branch level, while
+cherry-picking works at the commit level. This means that a merge can
+carry over the changes from 1, 10, or 1000 commits with equal ease,
+which in turn means the workflow scales much better to a large number
+of contributors (and contributions). Merges are also easier to
+understand because a merge commit is a "promise" that all changes from
+all its parents are now included.
+
+There is a tradeoff of course: merges require a more careful branch
+management. The following subsections discuss the important points.
+
+
+Graduation
+~~~~~~~~~~
+
+As a given feature goes from experimental to stable, it also
+"graduates" between the corresponding branches of the software.
+`git.git` uses the following 'integration branches':
+
+* 'maint' tracks the commits that should go into the next "maintenance
+ release", i.e., update of the last released stable version;
+
+* 'master' tracks the commits that should go into the next release;
+
+* 'next' is intended as a testing branch for topics being tested for
+ stability for master.
+
+There is a fourth official branch that is used slightly differently:
+
+* 'pu' (proposed updates) is an integration branch for things that are
+ not quite ready for inclusion yet (see "Integration Branches"
+ below).
+
+Each of the four branches is usually a direct descendant of the one
+above it.
+
+Conceptually, the feature enters at an unstable branch (usually 'next'
+or 'pu'), and "graduates" to 'master' for the next release once it is
+considered stable enough.
+
+
+Merging upwards
+~~~~~~~~~~~~~~~
+
+The "downwards graduation" discussed above cannot be done by actually
+merging downwards, however, since that would merge 'all' changes on
+the unstable branch into the stable one. Hence the following:
+
+.Merge upwards
+[caption="Rule: "]
+=====================================
+Always commit your fixes to the oldest supported branch that require
+them. Then (periodically) merge the integration branches upwards into each
+other.
+=====================================
+
+This gives a very controlled flow of fixes. If you notice that you
+have applied a fix to e.g. 'master' that is also required in 'maint',
+you will need to cherry-pick it (using linkgit:git-cherry-pick[1])
+downwards. This will happen a few times and is nothing to worry about
+unless you do it very frequently.
+
+
+Topic branches
+~~~~~~~~~~~~~~
+
+Any nontrivial feature will require several patches to implement, and
+may get extra bugfixes or improvements during its lifetime.
+
+Committing everything directly on the integration branches leads to many
+problems: Bad commits cannot be undone, so they must be reverted one
+by one, which creates confusing histories and further error potential
+when you forget to revert part of a group of changes. Working in
+parallel mixes up the changes, creating further confusion.
+
+Use of "topic branches" solves these problems. The name is pretty
+self explanatory, with a caveat that comes from the "merge upwards"
+rule above:
+
+.Topic branches
+[caption="Rule: "]
+=====================================
+Make a side branch for every topic (feature, bugfix, ...). Fork it off
+at the oldest integration branch that you will eventually want to merge it
+into.
+=====================================
+
+Many things can then be done very naturally:
+
+* To get the feature/bugfix into an integration branch, simply merge
+ it. If the topic has evolved further in the meantime, merge again.
+ (Note that you do not necessarily have to merge it to the oldest
+ integration branch first. For example, you can first merge a bugfix
+ to 'next', give it some testing time, and merge to 'maint' when you
+ know it is stable.)
+
+* If you find you need new features from the branch 'other' to continue
+ working on your topic, merge 'other' to 'topic'. (However, do not
+ do this "just habitually", see below.)
+
+* If you find you forked off the wrong branch and want to move it
+ "back in time", use linkgit:git-rebase[1].
+
+Note that the last point clashes with the other two: a topic that has
+been merged elsewhere should not be rebased. See the section on
+RECOVERING FROM UPSTREAM REBASE in linkgit:git-rebase[1].
+
+We should point out that "habitually" (regularly for no real reason)
+merging an integration branch into your topics -- and by extension,
+merging anything upstream into anything downstream on a regular basis
+-- is frowned upon:
+
+.Merge to downstream only at well-defined points
+[caption="Rule: "]
+=====================================
+Do not merge to downstream except with a good reason: upstream API
+changes affect your branch; your branch no longer merges to upstream
+cleanly; etc.
+=====================================
+
+Otherwise, the topic that was merged to suddenly contains more than a
+single (well-separated) change. The many resulting small merges will
+greatly clutter up history. Anyone who later investigates the history
+of a file will have to find out whether that merge affected the topic
+in development. An upstream might even inadvertently be merged into a
+"more stable" branch. And so on.
+
+
+Throw-away integration
+~~~~~~~~~~~~~~~~~~~~~~
+
+If you followed the last paragraph, you will now have many small topic
+branches, and occasionally wonder how they interact. Perhaps the
+result of merging them does not even work? But on the other hand, we
+want to avoid merging them anywhere "stable" because such merges
+cannot easily be undone.
+
+The solution, of course, is to make a merge that we can undo: merge
+into a throw-away branch.
+
+.Throw-away integration branches
+[caption="Rule: "]
+=====================================
+To test the interaction of several topics, merge them into a
+throw-away branch. You must never base any work on such a branch!
+=====================================
+
+If you make it (very) clear that this branch is going to be deleted
+right after the testing, you can even publish this branch, for example
+to give the testers a chance to work with it, or other developers a
+chance to see if their in-progress work will be compatible. `git.git`
+has such an official throw-away integration branch called 'pu'.
+
+
+DISTRIBUTED WORKFLOWS
+---------------------
+
+After the last section, you should know how to manage topics. In
+general, you will not be the only person working on the project, so
+you will have to share your work.
+
+Roughly speaking, there are two important workflows: merge and patch.
+The important difference is that the merge workflow can propagate full
+history, including merges, while patches cannot. Both workflows can
+be used in parallel: in `git.git`, only subsystem maintainers use
+the merge workflow, while everyone else sends patches.
+
+Note that the maintainer(s) may impose restrictions, such as
+"Signed-off-by" requirements, that all commits/patches submitted for
+inclusion must adhere to. Consult your project's documentation for
+more information.
+
+
+Merge workflow
+~~~~~~~~~~~~~~
+
+The merge workflow works by copying branches between upstream and
+downstream. Upstream can merge contributions into the official
+history; downstream base their work on the official history.
+
+There are three main tools that can be used for this:
+
+* linkgit:git-push[1] copies your branches to a remote repository,
+ usually to one that can be read by all involved parties;
+
+* linkgit:git-fetch[1] that copies remote branches to your repository;
+ and
+
+* linkgit:git-pull[1] that does fetch and merge in one go.
+
+Note the last point. Do 'not' use 'git-pull' unless you actually want
+to merge the remote branch.
+
+Getting changes out is easy:
+
+.Push/pull: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+`git push <remote> <branch>` and tell everyone where they can fetch
+from.
+=====================================
+
+You will still have to tell people by other means, such as mail. (Git
+provides the linkgit:git-request-pull[1] to send preformatted pull
+requests to upstream maintainers to simplify this task.)
+
+If you just want to get the newest copies of the integration branches,
+staying up to date is easy too:
+
+.Push/pull: Staying up to date
+[caption="Recipe: "]
+=====================================
+Use `git fetch <remote>` or `git remote update` to stay up to date.
+=====================================
+
+Then simply fork your topic branches from the stable remotes as
+explained earlier.
+
+If you are a maintainer and would like to merge other people's topic
+branches to the integration branches, they will typically send a
+request to do so by mail. Such a request looks like
+
+-------------------------------------
+Please pull from
+ <url> <branch>
+-------------------------------------
+
+In that case, 'git-pull' can do the fetch and merge in one go, as
+follows.
+
+.Push/pull: Merging remote topics
+[caption="Recipe: "]
+=====================================
+`git pull <url> <branch>`
+=====================================
+
+Occasionally, the maintainer may get merge conflicts when he tries to
+pull changes from downstream. In this case, he can ask downstream to
+do the merge and resolve the conflicts themselves (perhaps they will
+know better how to resolve them). It is one of the rare cases where
+downstream 'should' merge from upstream.
+
+
+Patch workflow
+~~~~~~~~~~~~~~
+
+If you are a contributor that sends changes upstream in the form of
+emails, you should use topic branches as usual (see above). Then use
+linkgit:git-format-patch[1] to generate the corresponding emails
+(highly recommended over manually formatting them because it makes the
+maintainer's life easier).
+
+.format-patch/am: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+* `git format-patch -M upstream..topic` to turn them into preformatted
+ patch files
+* `git send-email --to=<recipient> <patches>`
+=====================================
+
+See the linkgit:git-format-patch[1] and linkgit:git-send-email[1]
+manpages for further usage notes.
+
+If the maintainer tells you that your patch no longer applies to the
+current upstream, you will have to rebase your topic (you cannot use a
+merge because you cannot format-patch merges):
+
+.format-patch/am: Keeping topics up to date
+[caption="Recipe: "]
+=====================================
+`git pull --rebase <url> <branch>`
+=====================================
+
+You can then fix the conflicts during the rebase. Presumably you have
+not published your topic other than by mail, so rebasing it is not a
+problem.
+
+If you receive such a patch series (as maintainer, or perhaps as a
+reader of the mailing list it was sent to), save the mails to files,
+create a new topic branch and use 'git-am' to import the commits:
+
+.format-patch/am: Importing patches
+[caption="Recipe: "]
+=====================================
+`git am < patch`
+=====================================
+
+One feature worth pointing out is the three-way merge, which can help
+if you get conflicts: `git am -3` will use index information contained
+in patches to figure out the merge base. See linkgit:git-am[1] for
+other options.

+ after the offending branch is fixed.
+Message-ID: <7vocz8a6zk.fsf@gitster.siamese.dyndns.org>

+Alan <alan@clueserver.org> said:
+
+ I have a master branch. We have a branch off of that that some
+ developers are doing work on. They claim it is ready. We merge it
+ into the master branch. It breaks something so we revert the merge.
+ They make changes to the code. they get it to a point where they say
+ it is ok and we merge again.
+
+ When examined, we find that code changes made before the revert are
+ not in the master branch, but code changes after are in the master
+ branch.
+
+and asked for help recovering from this situation.
+
+The history immediately after the "revert of the merge" would look like
+this:
+
+ ---o---o---o---M---x---x---W
+ /
+ ---A---B
+
+where A and B are on the side development that was not so good, M is the
+merge that brings these premature changes into the mainline, x are changes
+unrelated to what the side branch did and already made on the mainline,
+and W is the "revert of the merge M" (doesn't W look M upside down?).
+IOW, "diff W^..W" is similar to "diff -R M^..M".
+
+Such a "revert" of a merge can be made with:
+
+ $ git revert -m 1 M
+
+After the develpers of the side branch fixes their mistakes, the history
+may look like this:
+
+ ---o---o---o---M---x---x---W---x
+ /
+ ---A---B-------------------C---D
+
+where C and D are to fix what was broken in A and B, and you may already
+have some other changes on the mainline after W.
+
+If you merge the updated side branch (with D at its tip), none of the
+changes made in A nor B will be in the result, because they were reverted
+by W. That is what Alan saw.
+
+Linus explains the situation:
+
+ Reverting a regular commit just effectively undoes what that commit
+ did, and is fairly straightforward. But reverting a merge commit also
+ undoes the _data_ that the commit changed, but it does absolutely
+ nothing to the effects on _history_ that the merge had.
+
+ So the merge will still exist, and it will still be seen as joining
+ the two branches together, and future merges will see that merge as
+ the last shared state - and the revert that reverted the merge brought
+ in will not affect that at all.
+
+ So a "revert" undoes the data changes, but it's very much _not_ an
+ "undo" in the sense that it doesn't undo the effects of a commit on
+ the repository history.
+
+ So if you think of "revert" as "undo", then you're going to always
+ miss this part of reverts. Yes, it undoes the data, but no, it doesn't
+ undo history.
+
+In such a situation, you would want to first revert the previous revert,
+which would make the history look like this:
+
+ ---o---o---o---M---x---x---W---x---Y
+ /
+ ---A---B-------------------C---D
+
+where Y is the revert of W. Such a "revert of the revert" can be done
+with:
+
+ $ git revert W
+
+This history would (ignoring possible conflicts between what W and W..Y
+changed) be equivalent to not having W nor Y at all in the history:
+
+ ---o---o---o---M---x---x-------x----
+ /
+ ---A---B-------------------C---D
+
+and merging the side branch again will not have conflict arising from an
+earlier revert and revert of the revert.
+
+ ---o---o---o---M---x---x-------x-------*
+ / /
+ ---A---B-------------------C---D
+
+Of course the changes made in C and D still can conflict with what was
+done by any of the x, but that is just a normal merge conflict.
+
+On the other hand, if the developers of the side branch discarded their
+faulty A and B, and redone the changes on top of the updated mainline
+after the revert, the history would have looked like this:
+
+ ---o---o---o---M---x---x---W---x---x
+ / \
+ ---A---B A'--B'--C'
+
+If you reverted the revert in such a case as in the previous example:
+
+ ---o---o---o---M---x---x---W---x---x---Y---*
+ / \ /
+ ---A---B A'--B'--C'
+
+where Y is the revert of W, A' and B'are rerolled A and B, and there may
+also be a further fix-up C' on the side branch. "diff Y^..Y" is similar
+to "diff -R W^..W" (which in turn means it is similar to "diff M^..M"),
+and "diff A'^..C'" by definition would be similar but different from that,
+because it is a rerolled series of the earlier change. There will be a
+lot of overlapping changes that result in conflicts. So do not do "revert
+of revert" blindly without thinking..
+
+ ---o---o---o---M---x---x---W---x---x
+ / \
+ ---A---B A'--B'--C'
+
+In the history with rebased side branch, W (and M) are behind the merge
+base of the updated branch and the tip of the mainline, and they should
+merge without the past faulty merge and its revert getting in the way.
+
+To recap, these are two very different scenarios, and they want two very
+different resolution strategies:
+
+ - If the faulty side branch was fixed by adding corrections on top, then
+ doing a revert of the previous revert would be the right thing to do.
+
+ - If the faulty side branch whose effects were discarded by an earlier
+ revert of a merge was rebuilt from scratch (i.e. rebasing and fixing,
+ as you seem to have interpreted), then re-merging the result without
+ doing anything else fancy would be the right thing to do.
+
+However, there are things to keep in mind when reverting a merge (and
+reverting such a revert).
+
+For example, think about what reverting a merge (and then reverting the
+revert) does to bisectability. Ignore the fact that the revert of a revert
+is undoing it - just think of it as a "single commit that does a lot".
+Because that is what it does.
+
+When you have a problem you are chasing down, and you hit a "revert this
+merge", what you're hitting is essentially a single commit that contains
+all the changes (but obviously in reverse) of all the commits that got
+merged. So it's debugging hell, because now you don't have lots of small
+changes that you can try to pinpoint which _part_ of it changes.
+
+But does it all work? Sure it does. You can revert a merge, and from a
+purely technical angle, git did it very naturally and had no real
+troubles. It just considered it a change from "state before merge" to
+"state after merge", and that was it. Nothing complicated, nothing odd,
+nothing really dangerous. Git will do it without even thinking about it.
+
+So from a technical angle, there's nothing wrong with reverting a merge,
+but from a workflow angle it's something that you generally should try to
+avoid.

History Simplification
~~~~~~~~~~~~~~~~~~~~~~
-When optional paths are given, 'git rev-list' simplifies commits with
-various strategies, according to the options you have selected.
+Sometimes you are only interested in parts of the history, for example the
+commits modifying a particular <path>. But there are two parts of
+'History Simplification', one part is selecting the commits and the other
+is how to do it, as there are various strategies to simplify the history.
+
+The following options select the commits to be shown:
+
+<paths>::
+
+ Commits modifying the given <paths> are selected.
+
+--simplify-by-decoration::
+
+ Commits that are referred by some branch or tag are selected.
+
+Note that extra commits can be shown to give a meaningful history.
+
+The following options affect the way the simplification is performed:
+
+Default mode::
+
+ Simplifies the history to the simplest history explaining the
+ final state of the tree. Simplest because it prunes some side
+ branches if the end result is the same (i.e. merging branches
+ with the same content)
+
+--full-history::
+
+ As the default mode but does not prune some history.
+
+--dense::
+
+ Only the selected commits are shown, plus some to have a
+ meaningful history.
+
+--sparse::
+
+ All commits in the simplified history are shown.
+
+--simplify-merges::
+
+ Additional option to '--full-history' to remove some needless
+ merges from the resulting history, as there are no selected
+ commits contributing to this merge.
+
+A more detailed explanation follows.
Suppose you specified `foo` as the <paths>. We shall call commits
that modify `foo` !TREESAME, and the rest TREESAME. (In a diff
@@ -413,6 +472,56 @@ Note that without '\--full-history', this still simplifies merges: if
one of the parents is TREESAME, we follow only that one, so the other
sides of the merge are never walked.
+Finally, there is a fourth simplification mode available:
+
+--simplify-merges::
+
+ First, build a history graph in the same way that
+ '\--full-history' with parent rewriting does (see above).
++
+Then simplify each commit `C` to its replacement `C'` in the final
+history according to the following rules:
++
+--
+* Set `C'` to `C`.
++
+* Replace each parent `P` of `C'` with its simplification `P'`. In
+ the process, drop parents that are ancestors of other parents, and
+ remove duplicates.
++
+* If after this parent rewriting, `C'` is a root or merge commit (has
+ zero or >1 parents), a boundary commit, or !TREESAME, it remains.
+ Otherwise, it is replaced with its only parent.
+--
++
+The effect of this is best shown by way of comparing to
+'\--full-history' with parent rewriting. The example turns into:
++
+-----------------------------------------------------------------------
+ .-A---M---N---O
+ / / /
+ I B D
+ \ / /
+ `---------'
+-----------------------------------------------------------------------
++
+Note the major differences in `N` and `P` over '\--full-history':
++
+--
+* `N`'s parent list had `I` removed, because it is an ancestor of the
+ other parent `M`. Still, `N` remained because it is !TREESAME.
++
+* `P`'s parent list similarly had `I` removed. `P` was then
+ removed completely, because it had one parent and is TREESAME.
+--
+
+The '\--simplify-by-decoration' option allows you to view only the
+big picture of the topology of the history, by omitting commits
+that are not referenced by tags. Commits are marked as !TREESAME
+(in other words, kept after history simplification rules described
+above) if (1) they are referenced by tags, or (2) they change the
+contents of the paths given on the command line. All other
+commits are marked as TREESAME (subject to be simplified away).
