f0e278b1b7 check_everything_connected(): refactor to use an iterator
We will be using the same "rev-list --verify-objects" logic to add a
sanity check to the receiving end of "git push" in the same way, but the
list of commits that are checked come from a structure with a different
shape over there.

Update the function to take an iterator to make it easier to reuse it in
different contexts.

6d4bb3833c fetch: verify we have everything we need before updating our ref
The "git fetch" command works in two phases. The remote side tells us what
objects are at the tip of the refs we are fetching from, and transfers the
objects missing from our side. After storing the objects in our repository,
we update our remote tracking branches to point at the updated tips of the
refs.

A broken or malicious remote side could send a perfectly well-formed pack
data during the object transfer phase, but there is no guarantee that the
given data actually fill the gap between the objects we originally had and
the refs we are updating to.

Although this kind of breakage can be caught by running fsck after a
fetch, it is much cheaper to verify that everything that is reachable from
the tips of the refs we fetched are indeed fully connected to the tips of
our current set of refs before we update them.

18322badc2 fetch: skip on-demand checking when no submodules are configured
It makes no sense to do the - possibly very expensive - call to "rev-list
<new-ref-sha1> --not --all" in check_for_new_submodule_commits() when
there aren't any submodules configured.

Leave check_for_new_submodule_commits() early when no name <-> path
mappings for submodules are found in the configuration. To make that work
reading the configuration had to be moved further up in cmd_fetch(), as
doing that after the actual fetch of the superproject was too late.

e2b239722a for-each-ref: add split message parts to %(contents:*).
The %(body) placeholder returns the whole body of a tag or
commit, including the signature. However, callers may want
to get just the body without signature, or just the
signature.

Rather than change the meaning of %(body), which might break
some scripts, this patch introduces a new set of
placeholders which break down the %(contents) placeholder
into its constituent parts.

and with tests by me]

7f6e275bc0 for-each-ref: handle multiline subjects like --pretty
Generally the format of a git tag or commit message is:

  subject

  body body body
  body body body

However, we occasionally see multiline subjects like:

  subject
  with multiple
  lines

  body body body
  body body body

The rest of git treats these multiline subjects as something
to be concatenated and shown as a single line (e.g., "git
log --pretty=format:%s" will do so since f53bd74). For
consistency, for-each-ref should do the same with its
"%(subject)".

7ec0f31eec for-each-ref: refactor subject and body placeholder parsing
The find_subpos function was a little hard to use, as well
as to read. It would sometimes write into the subject and
body pointers, and sometimes not. The body pointer sometimes
could be compared to subject, and sometimes not. When
actually duplicating the subject, the caller was forced to
figure out again how long the subject is (which is not too
big a deal when the subject is a single line, but hard to
extend).

The refactoring makes the function more straightforward, both
to read and to use. We will always put something into the
subject and body pointers, and we return explicit lengths
for them, too.

This lays the groundwork both for more complex subject
parsing (e.g., multiline), as well as splitting the body
into subparts (like the text versus the signature).

5879f5684c remove prefix argument from pathspec_prefix
Passing a prefix to a function that is supposed to find the prefix is
strange. And it's really only used if the pathspec is NULL. Make the
callers handle this case instead.

As we are always returning a fresh copy of a string (or NULL), change the

5a48d24012 rev-list --verify-object
Often we want to verify everything reachable from a given set of commits
are present in our repository and connected without a gap to the tips of
our refs. We used to do this for this purpose:

    $ rev-list --objects $commits_to_be_tested --not --all

Even though this is good enough for catching missing commits and trees,
we show the object name but do not verify their existence, let alone their
well-formedness, for the blob objects at the leaf level.

Add a new "--verify-object" option so that we can catch missing and broken
blobs as well.

b6194678b0 Documentation: clarify "git clean -e <pattern>"
The current explanation of -e can be misread as allowing the user to say

    I know 'git clean -XYZ' (substitute -XYZ with any option and/or
    parameter) will remove paths A, B, and C, and I want them all removed
    except for paths matching this pattern by adding '-e C' to the same
    command line, i.e. 'git clean -e C -XYZ'.

But that is not what this option does. It augments the set of ignore rules
from the command line, just like the same "-e <pattern>" argument does
with the "ls-files" command (the user could probably pass "-e \!C" to tell
the command to clean everything the command would normally remove, except
for C). Also error out when both -x and -e are given with an explanation of
what -e means---it is a symptom of misunderstanding what -e does.

It also fixes small style nit in the parameter to add_exclude() call. The
current code only works because EXC_CMDL happens to be defined as 0.

When asked if "refs///heads/master" is valid, check-ref-format says "Yes,
it is well formed", and when asked to print canonical form, it shows
"refs/heads/master". This is so that it can be tucked after "$GIT_DIR/"
to form a valid pathname for a loose ref, and we normalize a pathname like
"$GIT_DIR/refs///heads/master" to de-dup the slashes in it.

Similarly, when asked if "/refs/heads/master" is valid, check-ref-format
says "Yes, it is Ok", but the leading slash is not removed when printing,
leading to "$GIT_DIR//refs/heads/master".

Fix it to make sure such leading slashes are removed.  Add tests that such

e6baf4a1ae clone: clone from a repository with relative alternates
Cloning from a local repository blindly copies or hardlinks all the files
under objects/ hierarchy. This results in two issues:

 - If the repository cloned has an "objects/info/alternates" file, and the
   command line of clone specifies --reference, the ones specified on the
   command line get overwritten by the copy from the original repository.

 - An entry in a "objects/info/alternates" file can specify the object
   stores it borrows objects from as a path relative to the "objects/"
   directory. When cloning a repository with such an alternates file, if
   the new repository is not sitting next to the original repository, such
   relative paths needs to be adjusted so that they can be used in the new
   repository.

This updates add_to_alternates_file() to take the path to the alternate
object store, including the "/objects" part at the end (earlier, it was
taking the path to $GIT_DIR and was adding "/objects" itself), as it is
technically possible to specify in objects/info/alternates file the path
of a directory whose name does not end with "/objects".

55c4a67307 Prevent force-updating of the current branch
"git branch -M <foo> <current-branch>" allows updating the current branch
which HEAD points, without the necessary house-keeping that git reset
normally does to make this operation sensible. It also leaves the reflog
in a confusing state (you would be warned when trying to read it).

"git checkout -B <current branch> <foo>" is also partly vulnerable to this
bug; due to inconsistent pre-flight checks it would perform half of its
task and then abort just before rewriting the branch. Again this
manifested itself as the index file getting out-of-sync with HEAD.

"git branch -f" already guarded against this problem, and aborts with
a fatal error.

Update "git branch -M", "git checkout -B" and "git branch -f" to share the
same check before allowing a branch to be created. These prevent you from
updating the current branch.

We considered suggesting the use of "git reset" in the failure message
but concluded that it was not possible to discern what the user was
actually trying to do.

d2b17b3220 push: Don't push a repository with unpushed submodules
When working with submodules it is easy to forget to push a
submodule to the server but pushing a super-project that
contains a commit for that submodule. The result is that the
superproject points at a submodule commit that is not available
on the server.

This adds the option --recurse-submodules=check to push. When
using this option git will check that all submodule commits that
are about to be pushed are present on a remote of the submodule.

To be able to use a combined diff, disabling a diff callback has
been removed from combined-diff.c.

c9bfb95348 want_color: automatically fallback to color.ui
All of the "do we want color" flags default to -1 to
indicate that we don't have any color configured. This value
is handled in one of two ways:

  1. In porcelain, we check early on whether the value is
     still -1 after reading the config, and set it to the
     value of color.ui (which defaults to 0).

  2. In plumbing, it stays untouched as -1, and want_color
     defaults it to off.

This works fine, but means that every porcelain has to check
and reassign its color flag. Now that want_color gives us a
place to put this check in a single spot, we can do that,
simplifying the calling code.

callback that looks not only for the key that the user gave
us, but also for "diff.color" (for backwards compatibility)
and "color.ui" (as a fallback).

For the former, we use a custom variable to store the
diff.color value. For the latter, though, we store it in the
main "git_use_color_default" variable, turning on color.ui
for any other parts of git that respect this value.

In practice, this doesn't cause any bugs, because git-config
runs without caring about git_use_color_default, and then
exits. But it crosses module boundaries in an unusual and
confusing way, and it makes refactoring color handling
harder than it needs to be.

daa0c3d971 color: delay auto-color decision until point of use
When we read a color value either from a config file or from
the command line, we use git_config_colorbool to convert it
from the tristate always/never/auto into a single yes/no
boolean value.

This has some timing implications with respect to starting
a pager.

If we start (or decide not to start) the pager before
checking the colorbool, everything is fine. Either isatty(1)
will give us the right information, or we will properly
check for pager_in_use().

However, if we decide to start a pager after we have checked
the colorbool, things are not so simple. If stdout is a tty,
then we will have already decided to use color. However, the
user may also have configured color.pager not to use color
with the pager. In this case, we need to actually turn off
color. Unfortunately, the pager code has no idea which color
variables were turned on (and there are many of them
throughout the code, and they may even have been manipulated
after the colorbool selection by something like "--color" on
the command line).

This bug can be seen any time a pager is started after
config and command line options are checked. This has
affected "git diff" since 89d07f7 (diff: don't run pager if
user asked for a diff style exit code, 2007-08-12). It has
also affect the log family since 1fda91b (Fix 'git log'
early pager startup error case, 2010-08-24).

This patch splits the notion of parsing a colorbool and
actually checking the configuration. The "use_color"
variables now have an additional possible value,
GIT_COLOR_AUTO. Users of the variable should use the new
"want_color()" wrapper, which will lazily determine and
cache the auto-color decision.

06bb643b72 commit: reduce use of redundant global variables
The file-scope global variable head_sha1[] was used to hold the object
name of the current HEAD commit (unless we are about to make an initial
commit). Also there is an independent "static int initial_commit".

Fix all the functions on the call-chain that use these two variables to
take a new "(const) struct commit *current_head" argument instead, and
replace their uses, e.g. "if (initial_commit)" becomes "if (!current_head)"
and a reference to "head_sha1" becomes "current_head->object.sha1".

e269eb7946 git_config_colorbool: refactor stdout_is_tty handling
Usually this function figures out for itself whether stdout
is a tty. However, it has an extra parameter just to allow
git-config to override the auto-detection for its
--get-colorbool option.

Instead of an extra parameter, let's just use a global
variable. This makes calling easier in the common case, and
will make refactoring the colorbool code much simpler.

f1c9626105 diff: refactor COLOR_DIFF from a flag into an int
This lets us store more than just a bit flag for whether we
want color; we can also store whether we want automatic
colors. This can be useful for making the automatic-color
decision closer to the point of use.

This mostly just involves replacing DIFF_OPT_* calls with
manipulations of the flag. The biggest exception is that
calls to DIFF_OPT_TST must check for "o->use_color > 0",
which lets an "unknown" value (i.e., the default) stay at
"no color". In the previous code, a value of "-1" was not
propagated at all.

127f045222 revert: plug memory leak in "cherry-pick root commit" codepath
The empty tree passed as common ancestor to merge_trees() when
cherry-picking a parentless commit is allocated on the heap and never
freed.  Leaking such a small one-time allocation is not a very big
problem, but now that "git cherry-pick" can cherry-pick multiple
commits it can start to add up.

Avoid the leak by storing the fake tree exactly once in the BSS
section (i.e., use a static).  While at it, let's add a test to make
sure cherry-picking multiple parentless commits continues to work.

0f64bfa956 ls-files: fix pathspec display on error
The following sequence of commands reveals an issue with error
reporting of relative paths:

 $ mkdir sub
 $ cd sub
 $ git ls-files --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.
 $ git commit --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.

This bug is visible only if the normalized path (i.e., the relative
path from the repository root) is longer than the prefix.
Otherwise, the code skips over the normalized path and reads from
an unused memory location which still contains a leftover of the
original command line argument.

So instead, use the existing facilities to deal with relative paths
correctly.

Also fix inconsistency between "checkout" and "commit", e.g.

    $ cd Documentation
    $ git checkout nosuch.txt
    error: pathspec 'Documentation/nosuch.txt' did not match...
    $ git commit nosuch.txt
    error: pathspec 'nosuch.txt' did not match...

by propagating the prefix down the codepath that reports the error.

cf3e2486d6 revert: Propagate errors upwards from do_pick_commit
Currently, revert_or_cherry_pick can fail in two ways.  If it
encounters a conflict, it returns a positive number indicating the
intended exit status for the git wrapper to pass on; for all other
errors, it calls die().  The latter behavior is inconsiderate towards
callers, as it denies them the opportunity to recover from errors and
do other things.

After this patch, revert_or_cherry_pick will still return a positive
return value to indicate an exit status for conflicts as before, while
for some other errors, it will print an error message and return -1
instead of die()-ing.  The cmd_revert and cmd_cherry_pick are adjusted
to handle the fatal errors by die()-ing themselves.

While the full benefits of this patch will only be seen once all the
"die" calls are replaced with calls to "error", its immediate impact
is to change some "fatal:" messages to say "error:" and to add a new
"fatal: cherry-pick failed" message at the end when the operation
fails.

5a5d80f4ca revert: Introduce --continue to continue the operation
Introduce a new "git cherry-pick --continue" command which uses the
information in ".git/sequencer" to continue a cherry-pick that stopped
because of a conflict or other error.  It works by dropping the first
instruction from .git/sequencer/todo and performing the remaining
cherry-picks listed there, with options (think "-s" and "-X") from the
initial command listed in ".git/sequencer/opts".

So now you can do:

  $ git cherry-pick -Xpatience foo..bar
  ... description conflict in commit moo ...
  $ git cherry-pick --continue
  error: 'cherry-pick' is not possible because you have unmerged files.
  fatal: failed to resume cherry-pick
  $ echo resolved >conflictingfile
  $ git add conflictingfile && git commit
  $ git cherry-pick --continue; # resumes with the commit after "moo"

During the "git commit" stage, CHERRY_PICK_HEAD will aid by providing
the commit message from the conflicting "moo" commit.  Note that the
cherry-pick mechanism has no control at this stage, so the user is
free to violate anything that was specified during the first
cherry-pick invocation.  For example, if "-x" was specified during the
first cherry-pick invocation, the user is free to edit out the message
during commit time.  Note that the "--signoff" option specified at
cherry-pick invocation time is not reflected in the commit message
provided by CHERRY_PICK_HEAD; the user must take care to add
"--signoff" during the "git commit" invocation.

21afd08062 revert: Don't implicitly stomp pending sequencer operation
Protect the user from forgetting about a pending sequencer operation
by immediately erroring out when an existing cherry-pick or revert
operation is in progress like:

  $ git cherry-pick foo
  ... conflict ...
  $ git cherry-pick moo
  error: .git/sequencer already exists
  hint: A cherry-pick or revert is in progress
  hint: Use --reset to forget about it
  fatal: cherry-pick failed

A naive version of this would break the following established ways of
working:

  $ git cherry-pick foo
  ... conflict ...
  $ git reset --hard  # I actually meant "moo" when I said "foo"
  $ git cherry-pick moo

  $ git cherry-pick foo
  ... conflict ...
  $ git commit # commit the resolution
  $ git cherry-pick moo # New operation

However, the previous patches "reset: Make reset remove the sequencer
state" and "revert: Remove sequencer state when no commits are
pending" make sure that this does not happen.

2d27daa91d revert: Remove sequencer state when no commits are pending
When cherry-pick or revert is called on a list of commits, and a
conflict encountered somewhere in the middle, the data in
".git/sequencer" is required to continue the operation.  However, when
a conflict is encountered in the very last commit, the user will have
to "continue" after resolving the conflict and committing just so that
the sequencer state is removed.  This is how the current "rebase -i"
script works as well.

  $ git cherry-pick foo..bar
  ... conflict encountered while picking "bar" ...
  $ echo "resolved" >problematicfile
  $ git add problematicfile
  $ git commit
  $ git cherry-pick --continue # This would be a no-op

Change this so that the sequencer state is cleared when a conflict is
encountered in the last commit.  Incidentally, this patch makes sure
that some existing tests don't break when features like "--reset" and
"--continue" are implemented later in the series.

A better way to implement this feature is to get the last "git commit"
to remove the sequencer state.  However, that requires tighter
coupling between "git commit" and the sequencer, a goal that can be
pursued once the sequencer is made more general.

6280dfdc3b fast-export: quote paths in output
Many pathnames in a fast-import stream need to be quoted. In
particular:

  1. Pathnames at the end of an "M" or "D" line need quoting
     if they contain a LF or start with double-quote.

  2. Pathnames on a "C" or "R" line need quoting as above,
     but also if they contain spaces.

For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.

This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.

In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

f5114a40c0 git-check-attr: Normalize paths
Normalize the path arguments (relative to the working tree root, if
applicable) before looking up their attributes.  This requires passing
the prefix down the call chain.

This fixes two test cases for different reasons:

* "unnormalized paths" is fixed because the .gitattribute-file-seeking
  code is not confused into reading the top-level file twice.

* "relative paths" is fixed because the canonical pathnames are passed
  to get_check_attr() or get_all_attrs(), allowing them to match the
  pathname patterns as expected.

26ae337be1 revert: Introduce --reset to remove sequencer state
To explicitly remove the sequencer state for a fresh cherry-pick or
revert invocation, introduce a new subcommand called "--reset" to
remove the sequencer state.

Take the opportunity to publicly expose the sequencer paths, and a
generic function called "remove_sequencer_state" that various git
programs can use to remove the sequencer state in a uniform manner;
"git reset" uses it later in this series.  Introducing this public API
is also in line with our long-term goal of eventually factoring out
functions from revert.c into a generic commit sequencer.

21b14778a9 revert: Make pick_commits functionally act on a commit list
Apart from its central objective of calling into the picking
mechanism, pick_commits creates a sequencer directory, prepares a todo
list, and even acts upon the "--reset" subcommand.  This makes for a
bad API since the central worry of callers is to figure out whether or
not any conflicts were encountered during the cherry picking.  The
current API is like:

  if (pick_commits(opts) < 0)
     print "Something failed, we're not sure what"

So, change pick_commits so that it's only responsible for picking
commits in a loop and reporting any errors, leaving the rest to a new
function called pick_revisions.  Consequently, the API of pick_commits
becomes much clearer:

  act_on_subcommand(opts->subcommand);
  todo_list = prepare_todo_list();
  if (pick_commits(todo_list, opts) < 0)
     print "Error encountered while picking commits"

Now, callers can easily call-in to the cherry-picking machinery by
constructing an arbitrary todo list along with some options.

04d3d3cfc4 revert: Save data for continuing after conflict resolution
Ever since v1.7.2-rc1~4^2~7 (revert: allow cherry-picking more than
one commit, 2010-06-02), a single invocation of "git cherry-pick" or
"git revert" can perform picks of several individual commits.  To
implement features like "--continue" to continue the whole operation,
we will need to store some information about the state and the plan at
the beginning.  Introduce a ".git/sequencer/head" file to store this
state, and ".git/sequencer/todo" file to store the plan.  The head
file contains the SHA-1 of the HEAD before the start of the operation,
and the todo file contains an instruction sheet whose format is
inspired by the format of the "rebase -i" instruction sheet.  As a
result, a typical todo file looks like:

  pick 8537f0e submodule add: test failure when url is not configured
  pick 4d68932 submodule add: allow relative repository path
  pick f22a17e submodule add: clean up duplicated code
  pick 59a5775 make copy_ref globally available

Since SHA-1 hex is abbreviated using an find_unique_abbrev(), it is
unambiguous.  This does not guarantee that there will be no ambiguity
when more objects are added to the repository.

These two files alone are not enough to implement a "--continue" that
remembers the command-line options specified; later patches in the
series save them too.

These new files are unrelated to the existing .git/CHERRY_PICK_HEAD,
which will still be useful while committing after a conflict
resolution.

9044143ff1 revert: Don't create invalid replay_opts in parse_args
The "--ff" command-line option cannot be used with some other
command-line options.  However, parse_args still parses these
incompatible options into a replay_opts structure for use by the rest
of the program.  Although pick_commits, the current gatekeeper to the
cherry-pick machinery, checks the validity of the replay_opts
structure before before starting its operation, there will be multiple
entry points to the cherry-pick machinery in future.  To futureproof
the code and catch these errors in one place, make sure that an
invalid replay_opts structure is not created by parse_args in the
first place.  We still check the replay_opts structure for validity in
pick_commits, but this is an assert() now to emphasize that it's the
caller's responsibility to get it right.

89641472aa revert: Separate cmdline parsing from functional code
Currently, revert_or_cherry_pick sets up a default git config, parses
command-line arguments, before preparing to pick commits.  This makes
for a bad API as the central worry of callers is to assert whether or
not a conflict occured while cherry picking.  The current API is like:

  if (revert_or_cherry_pick(argc, argv, opts) < 0)
     print "Something failed, we're not sure what"

Simplify and rename revert_or_cherry_pick to pick_commits so that it
only has the responsibility of setting up the revision walker and
picking commits in a loop.  Transfer the remaining work to its
callers.  Now, the API is simplified as:

  if (parse_args(argc, argv, opts) < 0)
     print "Can't parse arguments"
  if (pick_commits(opts) < 0)
     print "Error encountered in picking machinery"

Later in the series, pick_commits will also serve as the starting
point for continuing a cherry-pick or revert.

80e1f79188 revert: Introduce struct to keep command-line options
The current code uses a set of file-scope static variables to tell the
cherry-pick/ revert machinery how to replay the changes, and
initializes them by parsing the command-line arguments.  In later
steps in this series, we would like to introduce an API function that
calls into this machinery directly and have a way to tell it what to
do.  Hence, introduce a structure to group these variables, so that
the API can take them as a single replay_options parameter.  The only
exception is the variable "me" -- remove it since it not an
independent option, and can be inferred from the action.

Unfortunately, this patch introduces a minor regression.  Parsing
strategy-option violates a C89 rule: Initializers cannot refer to
variables whose address is not known at compile time.  Currently, this
rule is violated by some other parts of Git as well, and it is
possible to get GCC to report these instances using the "-std=c89
-pedantic" option.

  commit = prepare_a_commit();

corresponding to this option is named "no_replay" for historical

corresponding to the "-x" command-line option a better name:
"record_origin".

a2ec3ad28f revert: Don't check lone argument in get_encoding
The only place get_encoding uses the global "commit" variable is when
writing an error message explaining that its lone argument was NULL.
Since the function's only caller ensures that a NULL argument isn't
passed, we can remove this check with two beneficial consequences:

1. Since the function doesn't use the global "commit" variable any
   more, it won't need to change when we eliminate the global variable
   later in the series.
2. Translators no longer need to localize an error message that will
   never be shown.

The add_message_to_msg function has some dead code, an unclear API,

git-revert & git-cherry-pick a builtin, 2007-03-01).  Today, tests in
t3505-cherry-pick-empty.sh indicate that not filling up an empty
commit message is the desired behavior.  Re-implement and inline the
function accordingly, with a beneficial side-effect: don't dereference
a NULL pointer when the commit doesn't have a delimeter after the
header.

8894d53580 commit: allow partial commits with relative paths
In order to do partial commits, git-commit overlays a tree on the
cache and checks pathspecs against the result. Currently, the
overlaying is done using "prefix" which prevents relative pathspecs
with ".." and absolute pathspec from matching when they refer to
files not under "prefix" and absent from the index, but still in
the tree (i.e.  files staged for removal).

The point of providing a prefix at all is performance optimization.
If we say there is no common prefix for the files of interest, then
we have to read the entire tree into the index.

But even if we cannot use the working directory as a prefix, we can
still figure out if there is a common prefix for all given paths,
and use that instead. The pathspec_prefix() routine from ls-files.c
does exactly that.

Any use of global variables is removed from pathspec_prefix() so
that it can be called from commit.c.

d04520e344 reset: give better reflog messages
The reset command creates its reflog entry from argv.
However, it does so after having run parse_options, which
means the only thing left in argv is any non-option
arguments. Thus you would end up with confusing reflog
entries like:

  $ git reset --hard HEAD^
  $ git reset --soft HEAD@{1}
  $ git log -2 -g --oneline
  8e46cad HEAD@{0}: HEAD@{1}: updating HEAD
  1eb9486 HEAD@{1}: HEAD^: updating HEAD

However, we must also consider that some scripts may set
GIT_REFLOG_ACTION before calling reset, and we need to show
their reflog action (with our text appended). For example:

  rebase -i (squash): updating HEAD

On top of that, we also set the ORIG_HEAD reflog action
(even though it doesn't generally exist). In that case, the
reset argument is somewhat meaningless, as it has nothing to
do with what's in ORIG_HEAD.

This patch changes the reset reflog code to show:

  $GIT_REFLOG_ACTION: updating {HEAD,ORIG_HEAD}

as before, but only if GIT_REFLOG_ACTION is set. Otherwise,
show:

   reset: moving to $rev

for HEAD, and:

   reset: updating ORIG_HEAD

for ORIG_HEAD (this is still somewhat superfluous, since we
are in the ORIG_HEAD reflog, obviously, but at least we now
mention which command was used to update it).

While we're at it, we can clean up the code a bit:

 - Use strbufs to make the message.

 - Use the "rev" parameter instead of showing all options.
   This makes more sense, since it is the only thing
   impacting the writing of the ref.

Because "diff --cached HEAD" showed an incorrect blob object name on the

6b01ecfe22 ref namespaces: Support remote repositories via upload-pack and receive-pack
Change upload-pack and receive-pack to use the namespace-prefixed refs
when working with the repository, and use the unprefixed refs when
talking to the client, maintaining the masquerade.  This allows
clone, pull, fetch, and push to work with a suitably configured
GIT_NAMESPACE.

receive-pack advertises refs outside the current namespace as .have refs
(as it currently does for refs in alternates), so that the client can
use them to minimize data transfer but will otherwise ignore them.

With appropriate configuration, this also allows http-backend to expose
namespaces as multiple repositories with different paths.  This only
requires setting GIT_NAMESPACE, which http-backend passes through to
upload-pack and receive-pack.

1b4bb16b9e pack-objects: optimize "recency order"
This optimizes the "recency order" (see pack-heuristics.txt in
Documentation/technical/ directory) used to order objects within a
packfile in three ways:

 - Commits at the tip of tags are written together, in the hope that
   revision traversal done in incremental fetch (which starts by
   putting them in a revision queue marked as UNINTERESTING) will see a
   better locality of these objects;

 - In the original recency order, trees and blobs are intermixed. Write
   trees together before blobs, in the hope that this will improve
   locality when running pathspec-limited revision traversal, i.e.
   "git log paths...";

 - When writing blob objects out, write the whole family of blobs that use
   the same delta base object together, by starting from the root of the
   delta chain, and writing its immediate children in a width-first
   manner, in the hope that this will again improve locality when reading
   blobs that belong to the same path, which are likely to be deltified
   against each other.

I tried various workloads in the Linux kernel repositories (HEAD at
v3.0-rc6-71-g4dd1b49) packed with v1.7.6 and with this patch, counting how
large seeks are needed between adjacent accesses to objects in the pack,
and the result looks promising.  The history has 2072052 objects, weighing
some 490MiB.

       Less than 2MiB seek:       81.73%      96.92%

   As the index-pack command already walks objects in the delta chain
   order, writing the blobs out in the delta chain order seems to
   drastically improve the locality of access.

Note that a half-a-gigabyte packfile comfortably fits in the buffer cache,
and you would unlikely to see much performance difference on a modern and
reasonably beefy machine with enough memory and local disks. Benchmarking
with cold cache (or over NFS) would be interesting.

This patch doesn't implement auto-detection of skew, but is the program
I used to calculate, and would provide the basis for such
auto-detection. It would be interesting to see average skew numbers for
popular repositories. You can run it as "git skew --all".

84054f79de clone: accept config options on the command line
Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.

In many cases, this is a minor convenience over something
like:

  git clone git://...
  git config core.whatever true

But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.

It also provides a mechanism for passing information to remote
helpers during a clone; the helpers may read the git config
to influence how they operate.

56baa61d01 archive: move file extension format-guessing lower
The process for guessing an archive output format based on
the filename is something like this:

  a. parse --output in cmd_archive; check the filename
     against a static set of mapping heuristics (right now
     it just matches ".zip" for zip files).

  b. if found, stick a fake "--format=zip" at the beginning
     of the arguments list (if the user did specify a
     --format manually, the later option will override our
     fake one)

  c. if it's a remote call, ship the arguments to the remote
     (including the fake), which will call write_archive on
     their end

  d. if it's local, ship the arguments to write_archive
     locally

There are two problems:

  1. The set of mappings is static and at too high a level.
     The write_archive level is going to check config for
     user-defined formats, some of which will specify
     extensions. We need to delay lookup until those are
     parsed, so we can match against them.

  2. For a remote archive call, our set of mappings (or
     formats) may not match the remote side's. This is OK in
     practice right now, because all versions of git
     understand "zip" and "tar". But as new formats are
     added, there is going to be a mismatch between what the
     client can do and what the remote server can do.

To fix (1), this patch refactors the location guessing to
happen at the write_archive level, instead of the
cmd_archive level. So instead of sticking a fake --format
field in the argv list, we actually pass a "name hint" down
the callchain; this hint is used at the appropriate time to
guess the format (if one hasn't been given already).

This patch leaves (2) unfixed. The name_hint is converted to
a "--format" option as before, and passed to the remote.
This means the local side's idea of how extensions map to
formats will take precedence.

Another option would be to pass the name hint to the remote
side and let the remote choose. This isn't a good idea for
two reasons:

  1. There's no room in the protocol for passing that
     information. We can pass a new argument, but older
     versions of git on the server will choke on it.

  2. Letting the remote side decide creates a silent
     inconsistency in user experience. Consider the case
     that the locally installed git knows about the "tar.gz"
     format, but a remote server doesn't.

     Running "git archive -o foo.tar.gz" will use the tar.gz
     format. If we use --remote, and the local side chooses
     the format, then we send "--format=tar.gz" to the
     remote, which will complain about the unknown format.
     But if we let the remote side choose the format, then
     it will realize that it doesn't know about "tar.gz" and
     output uncompressed tar without even issuing a warning.

588d0e834b tag: accept multiple patterns for --list
Until now, "git tag -l foo* bar*" would silently ignore the
second argument, showing only refs starting with "foo". It's
not just unfriendly not to take a second pattern; we
actually generated subtly wrong results (from the user's
perspective) because some of the requested tags were
omitted.

This patch allows an arbitrary number of patterns on the
command line; if any of them matches, the ref is shown.

While we're tweaking the documentation, let's also make it
clear that the pattern is fnmatch.

0c811a7a6f limit "contains" traversals based on commit timestamp
When looking for commits that contain other commits (e.g.,
via "git tag --contains"), we can end up traversing useless
portions of the graph. For example, if I am looking for a
tag that contains a commit made last week, there is not much
point in traversing portions of the history graph made five
years ago.

This optimization can provide massive speedups. For example,
doing "git tag --contains HEAD~200" in the linux-2.6
repository goes from:

  real    0m5.302s
  user    0m5.116s
  sys     0m0.184s

to:

  real    0m0.030s
  user    0m0.020s
  sys     0m0.008s

The downside is that we will no longer find some answers in
the face of extreme clock skew, as we will stop the
traversal early when seeing commits skewed too far into the
past.

Name-rev already implements a similar optimization, using a
"slop" of one day to allow for a certain amount of clock
skew in commit timestamps. This patch introduces a
"core.clockskew" variable, which allows specifying the
allowable amount of clock skew in seconds.  For safety, it
defaults to "none", causing a full traversal (i.e., no
change in behavior from previous versions).

ffc4b8012d tag: speed up --contains calculation
When we want to know if commit A contains commit B (or any
one of a set of commits, B through Z), we generally
calculate the merge bases and see if B is a merge base of A
(or for a set, if any of the commits B through Z have that
property).

When we are going to check a series of commits A1 through An
to see whether each contains B (e.g., because we are
deciding which tags to show with "git tag --contains"), we
do a series of merge base calculations. This can be very
expensive, as we repeat a lot of traversal work.

Instead, let's leverage the fact that we are going to use
the same --contains list for each tag, and mark areas of the
commit graph is definitely containing those commits, or
definitely not containing those commits. Later tags can then
stop traversing as soon as they see a previously calculated
answer.

This sped up "git tag --contains HEAD~200" in the linux-2.6
repository from:

  real    0m15.417s
  user    0m15.197s
  sys     0m0.220s

to:

  real    0m5.329s

ef49a7a012 zlib: zlib can only process 4GB at a time
The size of objects we read from the repository and data we try to put
into the repository are represented in "unsigned long", so that on larger
architectures we can handle objects that weigh more than 4GB.

But the interface defined in zlib.h to communicate with inflate/deflate
limits avail_in (how many bytes of input are we calling zlib with) and
avail_out (how many bytes of output from zlib are we ready to accept)
fields effectively to 4GB by defining their type to be uInt.

In many places in our code, we allocate a large buffer (e.g. mmap'ing a
large loose object file) and tell zlib its size by assigning the size to
avail_in field of the stream, but that will truncate the high octets of
the real size. The worst part of this story is that we often pass around
z_stream (the state object used by zlib) to keep track of the number of
used bytes in input/output buffer by inspecting these two fields, which
practically limits our callchain to the same 4GB limit.

Wrap z_stream in another structure git_zstream that can express avail_in
and avail_out in unsigned long. For now, just die() when the caller gives
a size that cannot be given to a single zlib call. In later patches in the
series, we would make git_inflate() and git_deflate() internally loop to
give callers an illusion that our "improved" version of zlib interface can
operate on a buffer larger than 4GB in one go.

c1921c184c clone: always fetch remote HEAD
In most cases, fetching the remote HEAD explicitly is
unnecessary. It's just a symref pointing to a branch which
we are already fetching, so we will already ask for its sha1.

However, if the remote has a detached HEAD, things are less
certain. We do not ask for HEAD's sha1, but we do try to
write it into a local detached HEAD. In most cases this is
fine, as the remote HEAD is pointing to some part of the
history graph that we will fetch via the refs.

But if the remote HEAD points to an "orphan" commit (one
which was is not an ancestor of any refs), then we will not
have the object, and update_ref will complain when we try to
write the detached HEAD, aborting the whole clone.

This patch makes clone always explicitly ask the remote for
the sha1 of its HEAD commit. In the non-detached case, this
is a no-op, as we were going to ask for that sha1 anyway. In
the regular detached case, this will add an extra "want" to
the protocol negotiation, but will not change the history
that gets sent. And in the detached orphan case, we will
fetch the orphaned history so that we can write it into our
local detached HEAD.

3de89c9d42 verify-pack: use index-pack --verify
This finally gets rid of the inefficient verify-pack implementation that
walks objects in the packfile in their object name order and replaces it
with a call to index-pack --verify. As a side effect, it also removes
packed_object_info_detail() API which is rather expensive.

As this changes the way errors are reported (verify-pack used to rely on
the usual runtime error detection routine unpack_entry() to diagnose the
CRC errors in an entry in the *.idx file; index-pack --verify checks the
whole *.idx file in one go), update a test that expected the string "CRC"
to appear in the error message.

Add a few more command line options that do not have to be advertised to

The eventual goal is to remove verify-pack implementation and redo it as a

c17b229454 checkout -b <name>: correctly detect existing branch
When create a new branch, we fed "refs/heads/<proposed name>" as a string
to get_sha1() and expected it to fail when a branch already exists.

The right way to check if a ref exists is to check with resolve_ref().

A naïve solution that might appear attractive but does not work is to
forbid slashes in get_describe_name() but that will not work. A describe
name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part
comes from a original tag name used in the repository the user ran the
describe command. A sick user could have a confusing hierarchical tag
whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar")
to generate a describe name "refs/heads/foobar-6-g02ac983", and we should
be able to use that name to refer to the object whose name is 02ac983.

08303c3636 grep: fix coloring of hunk marks between files
Commit 431d6e7b (grep: enable threading for context line printing)
split the printing of the "--\n" mark between results from different
files out into two places: show_line() in grep.c for the non-threaded
case and work_done() in builtin/grep.c for the threaded case.  Commit
55f638bd (grep: Colorize filename, line number, and separator) updated
the former, but not the latter, so the separators between files are
not colored if threads are used.

This patch merges the two.  In the threaded case, hunk marks are now
printed by show_line() for every file, including the first one, and the
very first mark is simply skipped in work_done().  This ensures that the
output is properly colored and works just as well.

9553d2b263 format-patch: preserve subject newlines with -k
In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it.  But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.

This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant.  This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

6bf139440c clean up calling conventions for pretty.c functions
We have a pretty_print_context representing the parameters
for a pretty-print session, but we did not use it uniformly.
As a result, functions kept growing more and more arguments.

Let's clean this up in a few ways:

  1. All pretty-print pp_* functions now take a context.
     This lets us reduce the number of arguments to these
     functions, since we were just passing around the
     context values separately.

  2. The context argument now has a cmit_fmt field, which
     was passed around separately. That's one less argument
     per function.

  3. The context argument always comes first, which makes
     calling a little more uniform.

This drops lines from some callers, and adds lines in a few
places (because we need an extra line to set the context's
fmt field). Overall, we don't save many lines, but the lines
that are there are a lot simpler and more readable.

5b38456ec7 mailinfo: always clean up rfc822 header folding
Without the "-k" option, mailinfo will convert a folded
subject header like:

  Subject: this is a
    subject that doesn't
    fit on one line

into a single line. With "-k", however, we assumed that
these newlines were significant and represented something
that the sending side would want us to preserve.

For messages created by format-patch, this assumption was
broken by a1f6baa (format-patch: wrap long header lines,
2011-02-23).  For messages sent by arbitrary MUAs, this was
probably never a good assumption to make, as they may have

This patch now joins folded lines with a single whitespace

3eafdc961f remote: allow "-t" with fetch mirrors
Commit 13fc2c1 (remote: disallow some nonsensical option
combinations, 2011-03-30) made it impossible to use "remote
add -t foo --mirror". The argument was that specifying
specific branches is useless because:

  1. Push mirrors do not want a refspec at all.

  2. The point of fetch mirroring is to use a broad refspec
     like "refs/*", but using "-t" overrides that.

Point (1) is valid; "-t" with push mirrors is useless. But
point (2) ignored another side effect of using --mirror: it
fetches the refs directly into the refs/ namespace as they
are found upstream, instead of placing them in a
separate-remote layout.

So 13fc2c1 was overly constrictive, and disallowed
reasonable specific-branch mirroring, like:

  git remote add -t heads/foo -t heads/bar --mirror=fetch

which makes the local "foo" and "bar" branches direct
mirrors of the remote, but does not fetch anything else.

This patch restores the original behavior, but only for
fetch mirrors.

The option can be used to check if read-tree with the same set of other
options like "-m" and "-u" would succeed without actually changing either
the index or the working tree.

The relevant tests in the t10?? range were extended to do a read-tree -n
before the real read-tree to make sure neither the index nor any local
files were changed with -n and the same exit code as without -n is
returned. The helper functions added for that purpose reside in the new
t/lib-read-tree.sh file.

The only exception is #13 in t1004 ("unlinking an un-unlink-able
symlink"). As this is an issue of wrong directory permissions it is not
detected with -n.

f807b3dcab checkout: make advice when reattaching the HEAD less loud
When switching away from a detached HEAD with "git checkout", we give a
listing of the commits about to be lost, and then tell how to resurrect
them since 8e2dc6a (commit: give final warning when reattaching HEAD to
leave commits behind, 2011-02-18).

This is a good safety measure for people who are not comfortable with the
detached HEAD state, but the advice on how to keep the state you just left
was given even to those who set advice.detachedHead to false.

Keep the warning and informational commit listing, but honor the setting
of advice.detachedHead to squelch the advice.

cff38a5e11 receive-pack: eliminate duplicate .have refs
When receiving a push, we advertise ref tips from any
alternate repositories, in case that helps the client send a
smaller pack. Since these refs don't actually exist in the
destination repository, we don't transmit the real ref
names, but instead use the pseudo-ref ".have".

If your alternate has a large number of duplicate refs (for
example, because it is aggregating objects from many related
repositories, some of which will have the same tags and
branch tips), then we will send each ".have $sha1" line
multiple times. This is a pointless waste of bandwidth, as
we are simply repeating the same fact to the client over and
over.

This patch eliminates duplicate .have refs early on. It does
so efficiently by sorting the complete list and skipping
duplicates. This has the side effect of re-ordering the
.have lines by ascending sha1; this isn't a problem, though,
as the original order was meaningless.

There is a similar .have system in fetch-pack, but it
does not suffer from the same problem. For each alternate
ref we consider in fetch-pack, we actually open the object
and mark it with the SEEN flag, so duplicates are
automatically culled.

114a6a889f refactor refs_from_alternate_cb to allow passing extra data
The foreach_alt_odb function triggers a callback for each
alternate object db we have, with room for a single void
pointer as data. Currently, we always call refs_from_alternate_cb
as the callback function, and then pass another callback (to
receive each ref individually) as the void pointer.

This has two problems:

  1. C technically forbids stuffing a function pointer into
     a "void *". In practice, this probably doesn't matter
     on any architectures git runs on, but it never hurts to
     follow the letter of the law.

  2. There is no room for an extra data pointer. Indeed, the
     alternate_ref_fn that refs_from_alternate_cb calls
     takes a void* for data, but we always pass it NULL.

Instead, let's properly stuff our function pointer into a
data struct, which also leaves room for an extra
caller-supplied data pointer. And to keep things simple for
existing callers, let's make a for_each_alternate_ref
function that takes care of creating the extra struct.

ea5f220821 fetch: avoid repeated commits in mark_complete
We add every local ref to a list so that we can mark them
and all of their ancestors back to a certain cutoff point.
However, if some refs point to the same commit, we will end
up adding them to the list many times.

Furthermore, since commit_lists are stored as linked lists,
we must do an O(n) traversal of the list in order to find
the right place to insert each commit. This makes building
the list O(n^2) in the number of refs.

For normal repositories, this isn't a big deal. We have a
few hundreds refs at most, and most of them are unique. But
consider an "alternates" repo that serves as an object
database for many other similar repos. For reachability, it
needs to keep a copy of the refs in each child repo. This
means it may have a large number of refs, many of which
point to the same commits.

By noting commits we have already added to the list, we can
shrink the size of "n" in such a repo to the number of
unique commits, which is on the order of what a normal repo
would contain (it's actually more than a normal repo, since child repos
may have branches at different states, but in practice it tends
to be much smaller than the list with duplicates).

Here are the results on one particular giant repo
(containing objects for all Rails forks on GitHub):

c3ab1a8e4c notes remove: allow removing more than one
While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.

Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.

Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.

a87247731e ls-remote: the --exit-code option reports "no matching refs"

command exit with status "2" when there is no refs to be listed, even when

This way, the caller can tell if we failed to contact the remote, or the
remote did not have what we wanted to see. Of course, you can inspect the
output from the command, which has been and will continue to be a valid
way to check the same thing.

feels wasteful.  No noticeable change intended.

cca2c172e0 git-grep: do not die upon -F/-P when grep.extendedRegexp is set.
The previous one made "git grep -P" fail when grep.extendedRegexp is
enabled.  That is a no-starter.  The option on the command line should
just make the command ignore the configured default.  The handling of "-F"
in the existing code has the same problem.

Instead of saying -G/-F/-E/-P incompatible with each other, just allow
the last one win.  That way, you can have "[alias] gr = grep -P" and
use Pcre for everyday work e.g. "git gr ':i?foo'", and append -G to the
aliased command line to override it e.g. "git gr -G '[Ff][Oo][Oo]'".

This patch makes git-grep die() when -P is used on command line together
with -E/--extended-regexp or -F/--fixed-strings.

This also makes it bail out when grep.extendedRegexp is enabled.

But `git grep -G -P pattern` and `git grep -E -G -P pattern` still work
because -G and -E set opts.regflags during parse_options() and there is
no way to detect `-G` or `-E -G`.

POSIX regexes, like consistent escaping rules, extended character

933e44d3a0 "add -p": work-around an old laziness that does not coalesce hunks
Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02),
"git add--interactive" behaves lazily and passes overlapping hunks to the
underlying "git apply" without coalescing.  This was partially corrected
by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are
still passed when the patch is edited.

Teach "git apply" the --allow-overlap option that disables a safety
feature that avoids misapplication of patches by not applying patches
to overlapping hunks, and pass this option form "add -p" codepath.

Do not even advertise the option, as this is merely a workaround, and the
correct fix is to make "add -p" correctly coalesce adjacent patch hunks.

9b01f0038b blame: tolerate bogus e-mail addresses a bit better
The names and e-mails are sanitized by fmt_ident() when creating commits,
so that they do not contain "<" nor ">", and the "committer" and "author"
lines in the commit object will always be in the form:

    ("author" | "committer") name SP "<" email ">" SP timestamp SP zone

When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".

We should instead look for SP followed by "<", to match the logic of the
side that formats these lines.

75973b2cb5 Fix "add -u" that sometimes fails to resolve unmerged paths
"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.

It ignored the output from the diff-files that indicated that a path is
unmerged.  For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.

As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.

Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.

The changes to the test vector in t2200 illustrates the nature of the bug
and the fix.  The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

ef803fd4b0 builtin/log.c: separate default and setup of cmd_log_init()
cmd_log_init() sets up some default rev options and then calls
setup_revisions(), so that a caller cannot set up own defaults: Either
they get overriden by cmd_log_init() (if set before) or they override
the command line (if set after). We even complain about this in a
comment to cmd_log_reflog().

Therefore, separate the two steps so that one can still call
cmd_log_init() or, alternatively, cmd_log_init_defaults() followed by
cmd_log_init_finish() (and set defaults in between).

No functional change so far.

0990248610 remote: deprecate --mirror
The configuration created by plain --mirror is dangerous and
useless, and we now have --mirror=fetch and --mirror=push to
replace it. Let's warn the user.

One alternative to this is to try to guess which type the
user wants. In a non-bare repository, a fetch mirror doesn't
make much sense, since it would overwrite local commits. But
in a bare repository, you might use either type, or even
both (e.g., if you are acting as an intermediate drop-point
across two disconnected networks).

So rather than try for complex heuristics, let's keep it
simple. The user knows what they're trying to do, so let
them tell us.

a9f5a3558d remote: separate the concept of push and fetch mirrors
git-remote currently has one option, "--mirror", which sets
up mirror configuration which can be used for either
fetching or pushing. It looks like this:

  [remote "mirror"]
    url = wherever
    fetch = +refs/*:refs/*
    mirror = true

However, a remote like this can be dangerous and confusing.
Specifically:

  1. If you issue the wrong command, it can be devastating.
     You are not likely to "push" when you meant to "fetch",
     but "git remote update" will try to fetch it, even if
     you intended the remote only for pushing. In either
     case, the results can be quite destructive. An
     unintended push will overwrite or delete remote refs,
     and an unintended fetch can overwrite local branches.

  2. The tracking setup code can produce confusing results.
     The fetch refspec above means that "git checkout -b new
     master" will consider refs/heads/master to come from
     the remote "mirror", even if you only ever intend to
     push to the mirror. It will set up the "new" branch to
     track mirror's refs/heads/master.

  3. The push code tries to opportunistically update
     tracking branches. If you "git push mirror foo:bar",
     it will see that we are updating mirror's
     refs/heads/bar, which corresponds to our local
     refs/heads/bar, and will update our local branch.

To solve this, we split the concept into "push mirrors" and
"fetch mirrors". Push mirrors set only remote.*.mirror,
solving (2) and (3), and making an accidental fetch write
only into FETCH_HEAD. Fetch mirrors set only the fetch
refspec, meaning an accidental push will not force-overwrite
or delete refs on the remote end.

The new syntax is "--mirror=<fetch|push>". For
compatibility, we keep "--mirror" as-is, setting up both
types simultaneously.

13fc2c1877 remote: disallow some nonsensical option combinations
It doesn't make sense to use "-m" on a mirror, since "-m"
sets up the HEAD symref in the remotes namespace, but with
mirror, we are by definition not using a remotes namespace.

Similarly, it does not make much sense to specify refspecs
with --mirror. For a mirror you plan to push to, those
refspecs will be ignored. For a mirror you are fetching
from, there is no point in mirroring, since the refspec
specifies everything you want to grab.

There is one case where "--mirror -t <X>" would be useful.
Because <X> is used as-is in the refspec, and because we
append it to to refs/, you could mirror a subset of the
hierarchy by doing:

  git remote add --mirror -t 'tags/*'

But using anything besides a single branch as an argument to
"-t" is not documented and only happens to work, so closing
it off is not a serious regression.

84a7e35eea Make "git notes add" more user-friendly when there are existing notes
Currently, "notes add" (without -f/--force) will abort when the given object
already has existing notes. This makes sense for the modes of "git notes add"
that would necessarily overwrite the old message (when using the -m/-F/-C/-c
options). However, when no options are given (meaning the notes are created
from scratch in the editor) it is not very user-friendly to abort on existing
notes, and forcing the user to run "git notes edit".

Instead, it is better to simply "redirect" to "git notes edit" automatically,
i.e. open the existing notes in the editor and let the user edit them.
This patch does just that.

This changes the behavior of "git notes add" without options when notes
already exist for the given object, but I doubt that many users really depend
on the previous failure from "git notes add" in this case.

44d8dc54e7 Fix potential local deadlock during fetch-pack
The fetch-pack/upload-pack protocol relies on the underlying transport
(local pipe or TCP socket) to have enough slack to allow one window worth
of data in flight without blocking the writer.  Traditionally we always
relied on being able to have two windows of 32 "have"s in flight (roughly
3k bytes) to stream.

The recent "progressive-stride" change allows "fetch-pack" to send up to
1024 "have"s without reading any response from "upload-pack".  The
outgoing pipe of "upload-pack" can be clogged with many ACK and NAK that
are unread, while "fetch-pack" is still stuffing its outgoing pipe with
more "have"s, leading to a deadlock.

Revert the change unless we are in stateless rpc (aka smart-http) mode, as
using a large window full of "have"s is still a good way to help reduce
the number of back-and-forth, and there is no buffering issue there (it is
strictly "ping-pong" without an overlap).

8e9182e091 enable "no-done" extension only when fetching over smart-http
When 'no-done' protocol extension is used, the upload-pack (i.e. the
server side) process stops listening to the fetch-pack after issuing the
final NAK, and starts sending the generated pack data back, but there may
be more "have" send by the latter in flight that the fetch-pack is
expecting to be responded with ACK/NAK.  This will typically result in a
deadlock (both will block on write that the other end never reads) or
SIGPIPE on the fetch-pack end (upload-pack will finish writing a small
pack and goes away).

Disable it unless fetch-pack is running under smart-http, where there is
no such streaming issue.

97b1b4f3a6 merge: merge unborn index before setting ref
When we merge into an unborn branch, there are basically two
steps:

  1. Write the sha1 of the new commit into the ref pointed
     to by HEAD.

  2. Update the index with the new content, and check it out
     to the working tree.

We currently do them in this order. However, (2) is the step
that is much more likely to fail, since it can be blocked by
things like untracked working tree files. When it does, the
merge fails and we are left with an empty index but an
updated HEAD.

This patch switches the order, so that a failure in updating
the index leaves us unchanged. Of course, a failure in
updating the ref now leaves us with an updated index and
mis-matched HEAD. That is arguably not much better, but it
is probably less likely to actually happen.

97d0b74a49 Improve tree_entry_interesting() handling code
t_e_i() can return -1 or 2 to early shortcut a search. Current code
may use up to two variables to handle it. One for saving return value
from t_e_i temporarily, one for saving return code 2.

The second variable is not needed. If we make sure the first variable
does not change until the next t_e_i() call, then we can do something
like this:

int ret = 0;

while (...) {
	if (ret != 2) {
		ret = t_e_i();
		if (ret < 0) /* no longer interesting */
			break;
		if (ret == 0) /* skip this round */
			continue;
	}
	/* ret > 0, interesting */
}

f0096c06bc Convert read_tree{,_recursive} to support struct pathspec
This patch changes behavior of the two functions. Previously it does
prefix matching only. Now it can also do wildcard matching.

All callers are updated. Some gain wildcard matching (archive,
checkout), others reset pathspec_item.has_wildcard to retain old
behavior (ls-files, ls-tree as they are plumbing).

ad5aeeded3 revision.c: introduce --min-parents and --max-parents options
Introduce --min-parents and --max-parents options which limit the
revisions to those commits which have at least (or at most) that many
commits, where negative arguments for --max-parents= denote infinity
(i.e. no upper limit).

In particular:

  --max-parents=1 is the same as --no-merges;
  --min-parents=2 is the same as --merges;
  --max-parents=0 shows only roots; and
  --min-parents=3 shows only octopus merges

Using --min-parents=n and --max-parents=m with n>m gives you what you ask
for (i.e. nothing) for obvious reasons, just like when you give --merges
(show only merge commits) and --no-merges (show only non-merge commits) at
the same time.

Also, introduce --no-min-parents and --no-max-parents to do the obvious
thing for convenience.

We compute the number of parents only when we limit by that, so there
is no performance impact when there are no limiters.

0be240cc65 checkout: tweak detached-orphan warning format
When orphaning a commit on a detached HEAD, the warning
currently looks like:

  Warning: you are leaving 3 commits behind, not connected to
  any of your branches:

   - commit subject 1
   - commit subject 2
   - commit subject 3

  If you want to keep them by creating a new branch, this
  may be a good time to do so with:

     git branch new_branch_name 933a615ab0bc566dcfd8c01ec8af159f770d3fe5

Instead of using the "-" list, let's provide a more
traditional oneline format, with the abbreviated sha1 before
each subject. Users are accustomed to seeing commits in this
format, and having the sha1 of each commit can be useful if
you want to cherry-pick instead of creating a new branch.

The new format looks like:

  Warning: you are leaving 3 commits behind, not connected to
  any of your branches:

    933a615 commit subject 1
    824fcde commit subject 2
    fa49b1a commit subject 3

36cfda1552 refs_from_alternate: helper to use refs from alternates
The receiving end of "git push" advertises the objects that the repository
itself does not use, but are at the tips of refs in other repositories
whose object databases are used as alternates for it. This helps it avoid
having to receive (and the pusher having to send) objects that are already
available to the receiving repository via the alternates mechanism.

Tweak the helper function that implements this feature, and move it to
transport.[ch] for future reuse by other programs.

The additional test demonstrates how this optimization is helping "git push",
and "git fetch" is ignorant about it.

31d713d069 mktag: avoid %td in format string
Since v1.7.0-rc0~34 (make "mktag" a built-in, 2010-01-22), git mktag
uses the C99-style %td format to print ptrdiff_t values.  It falls
back to %d when NO_C99_FORMAT is set, on the assumption that pre-C99
systems probably are using 32-bit pointers.

But many modern systems are 64-bit and

 * sometimes one wants to test the NO_C99_FORMAT fallbacks using a
   modern development platform;
 * some platforms (I'm looking at you, msvc) have not gotten with the
   program and are still C89-only.

These ptrdiff_t values are offsets from the beginning of a buffer, so
a size_t or uintmax_t would work about as well.  Use the latter so we
can take advantage of the PRIuMAX fallback in git-compat-util.h, even
on C99-challenged systems with 64-bit pointers.

9cba13ca5d standardize brace placement in struct definitions
In a struct definitions, unlike functions, the prevailing style is for
the opening brace to go on the same line as the struct name, like so:

 struct foo {
	int bar;
	char *baz;
 };

Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many
matches as 'struct [a-z_]*$'.

8f323c00dd config: drop support for GIT_CONFIG_NOGLOBAL
Now that test-lib sets $HOME to protect against pollution from user
settings, GIT_CONFIG_NOGLOBAL is not needed for use by the test
suite any more.  And as luck would have it, a quick code search
reveals no other users in the wild.

This patch does not affect GIT_CONFIG_NOSYSTEM, which is still
needed.

761ecf0bc7 fetch-pack: Implement no-done capability
If enabled on the connection "multi_ack_detailed no-done" as a
pair allows the remote upload-pack process to send a PACK down
to the client as soon as a "ACK %s ready" message was also sent.

Over git:// and ssh:// where a bi-directional stream is in place
this has very little difference over the classical version that
waits for the client to send a "done\n" line by itself.  It does
slightly reduce the latency involved to start the pack stream as
there is one less round-trip from client->server required.

Over smart HTTP this avoids needing to send a final RPC that has
all of the prior common objects.  Instead the server is able to
return a pack as soon as its ready to.  For many common users the
smart HTTP fetch is now just 2 requests: GET .../info/refs, and
a POST .../git-upload-pack to not only negotiate but also receive
the pack stream.  Only users who have more than 32 local unshared
commits with the remote will need additional requests to negotiate
a common merge base.

f2cba9299b fetch-pack: Finish negotation if remote replies "ACK %s ready"
If multi_ack_detailed was selected in the protocol capabilities
(both client and server are >= Git 1.6.6) the upload-pack side will
send "ACK %s ready" when it knows how to safely cut the graph and
produce a reasonable pack for the want list that was already sent
on the connection.

Upon receiving "ACK %s ready" there is no point in looking at
the remaining commits inside of rev_list.  Sending additional
"have %s" lines to the remote will not construct a smaller pack.
It is unlikely a commit older than the current cut point will have
a better delta base than the cut point itself has.

The original design of this code had fetch-pack empty rev_list by
marking a commit and its transitive ancestors COMMON whenever the
remote side said "ACK %s {continue,common}" and skipping over any
already COMMON commits during get_rev().  This approach does not
work when most of rev_list is actually COMMON_REF, commits that
are pointed to by a reference on the remote, which exist locally,
and which have not yet been sent to the remote as a "have %s" line.

Most of the common references are tags in the ref/tags namespace,
using points in the commit graph that are more than 1 commit apart.
In git.git itself, this is currently 340 tags, 339 of which point to
commits in the commit graph.  fetch-pack pushes all of these into
rev_list, but is unable to mark them COMMON and discard during a
remote's "ACK %s {continue,common}" because it does not parse through
the entire parent chain.  Not parsing the entire parent chain is
an optimization to avoid walking back to the roots of the repository.

Assuming the client is only following the remote (and does not make
its own local commits), the client needs 11 rounds to spin through
the entire list of tags (32 commits per round, ceil(339/32) == 11).
Unfortunately the server knows on the first "have %s" line that
it can produce a good pack, and does not need to see the remaining
320 tags in the other 10 rounds.

Over git:// and ssh:// this isn't as bad as it sounds, the client is
only transmitting an extra 16,000 bytes that it doesn't need to send.

Over smart HTTP, the client must do an additional 10 HTTP POST
requests, each of which incurs round-trip latency, and must upload
the entire state vector of all known common objects.  On the final
POST request, this is 16 KiB worth of data.

Fix all of this by clearing rev_list as soon as the remote side
says it can construct a pack.

dce9648916 Make the default abbrev length configurable
The default of 7 comes from fairly early in git development, when
seven hex digits was a lot (it covers about 250+ million hash
values). Back then I thought that 65k revisions was a lot (it was what
we were about to hit in BK), and each revision tends to be about 5-10
new objects or so, so a million objects was a big number.

These days, the kernel isn't even the largest git project, and even
the kernel has about 220k revisions (_much_ bigger than the BK tree
ever was) and we are approaching two million objects. At that point,
seven hex digits is still unique for a lot of them, but when we're
talking about just two orders of magnitude difference between number
of objects and the hash size, there _will_ be collisions in truncated
hash values. It's no longer even close to unrealistic - it happens all
the time.

We should both increase the default abbrev that was unrealistically
small, _and_ add a way for people to set their own default per-project
in the git config file.

This is the first step to first make it configurable; the default of 7
is not raised yet.

251df09be3 log: fix --max-count when used together with -S or -G
The --max-count limit is implemented by counting revisions in
get_revision(), but the -S and -G take effect later when running diff.
Hence "--max-count=10 -Sfoo" meant "examine the 10 first revisions, and
out of them, show only those changing the occurences of foo", not "show 10
revisions changing the occurences of foo".

In case the commit isn't actually shown, cancel the decrement of

8f0700dd33 fetch/pull: Add the 'on-demand' value to the --recurse-submodules option
Until now the --recurse-submodules option could only be used to either
fetch all populated submodules recursively or to disable recursion
completely. As fetch and pull now by default just fetch those submodules

88a21979c5 fetch/pull: recurse into submodules when necessary
To be able to access all commits of populated submodules referenced by the
superproject it is sufficient to only then let "git fetch" recurse into a
submodule when the new commits fetched in the superproject record new
commits for it. Having these commits present is extremely useful when
using the "--submodule" option to "git diff" (which is what "git gui" and
"gitk" do since 1.6.6), as all submodule commits needed for creating a
descriptive output can be accessed. Also merging submodule commits (added
in 1.7.3) depends on the submodule commits in question being present to
work. Last but not least this enables disconnected operation when using
submodules, as all commits necessary for a successful "git submodule
update -N" will have been fetched automatically. So we choose this mode as
the default for fetch and pull.

Before a new or changed ref from upstream is updated in update_local_ref()
"git rev-list <new-sha1> --not --branches --remotes" is used to determine
all newly fetched commits. These are then walked and diffed against their
parent(s) to see if a submodule has been changed. If that is the case, its
path is stored to be fetched after the superproject fetch is completed.

Using the "--recurse-submodules" or the "--no-recurse-submodules" option
disables the examination of the fetched refs because the result will be
ignored anyway.

There is currently no infrastructure for storing deleted and new
submodules in the .git directory of the superproject. That's why fetch and
pull for now only fetch submodules that are already checked out and are
not renamed.

In t7403 the "--no-recurse-submodules" argument had to be added to "git
pull" to avoid failure because of the moved upstream submodule repo.

bbc30f9963 add packet tracing debug code
This shows a trace of all packets coming in or out of a given
program. This can help with debugging object negotiation or
other protocol issues.

To keep the code changes simple, we operate at the lowest
level, meaning we don't necessarily understand what's in the
packets. The one exception is a packet starting with "PACK",
which causes us to skip that packet and turn off tracing
(since the gigantic pack data will not be interesting to
read, at least not in the trace format).

We show both written and read packets. In the local case,
this may mean you will see packets twice (written by the
sender and read by the receiver). However, for cases where
the other end is remote, this allows you to see the full
conversation.

Packet tracing can be enabled with GIT_TRACE_PACKET=<foo>,
where <foo> takes the same arguments as GIT_TRACE.

9d158601b3 apply: do not patch lines that were already patched
When looking for a place to apply a hunk, we used to check lines that
match the preimage of it, starting from the line that the patch wants to
apply the hunk at, looking forward and backward with increasing offsets
until we find a match.

Colin Guthrie found an interesting case where this misapplied a patch that
wanted to touch a preimage that consists of

                        }
                }

                return 0;
        }

which is a rather unfortunately common pattern.

The target version of the file originally had only one such location, but
the hunk immediately before that created another instance of such block of
lines, and find_pos() happily reported that the preimage of the hunk
matched what it wanted to modify.

Oops.

By marking the lines application of earlier hunks touched and preventing
match_fragment() from considering them as a match with preimage of other
hunks, we can reduce such an accident.

I also considered to teach apply_one_fragment() to take the offset we have
found while applying the previous hunk into account when looking for a
match with find_pos(), but dismissed that approach, because it would
sometimes work better but sometimes worse, depending on the difference
between the version the patch was created against and the version the
patch is being applied.

This does _not_ prevent misapplication of patches to a file that has many
similar looking blocks of lines and a preimage cannot identify which one
of them should be applied.  For that, we would need to scan beyond the
first match in find_pos(), and issue a warning (or error out).  That will
be a separate topic.

3c9fc074c2 index-pack --verify: read anomalous offsets from v2 idx file
A pack v2 .idx file usually records offset using 64-bit representation
only when the offset does not fit within 31-bit, but you can handcraft
your .idx file to record smaller offset using 64-bit, storing all zero
in the upper 4-byte.  By inspecting the original idx file when running
index-pack --verify, encode such low offsets that do not need to be in
64-bit but are encoded using 64-bit just like the original idx file so
that we can still validate the pack/idx pair by comparing the idx file
recomputed with the original.

e337a04de2 index-pack: --verify
Given an existing .pack file and the .idx file that describes it,
this new mode of operation reads and re-index the packfile and makes
sure the existing .idx file matches the result byte-for-byte.

All the objects in the .pack file are validated during this operation as
well.  Unlike verify-pack, which visits each object described in the .idx
file in the SHA-1 order, index-pack efficiently exploits the delta-chain
to avoid rebuilding the objects that are used as the base of deltified
objects over and over again while validating the objects, resulting in
much quicker verification of the .pack file and its .idx file.

This version however cannot verify a .pack/.idx pair with a handcrafted v2
index that uses 64-bit offset representation for offsets that would fit
within 31-bit. You can create such an .idx file by giving a custom offset
to --index-version option to the command.

6e7293e3ed git-add: make -A description clearer vs. -u
Currently, it sounds as if "notice removal of files" distinguishes "-A"

But both notice the removal, and only "-A" adds changes from untracked

2140b14064 commit: error out for missing commit message template
When "git commit" was rewritten in C (v1.5.4-rc0~78^2~30,
2007-11-08), a subtle bug in --template was introduced.  If the
file named by a --template parameter is missing, previously git
would error out with a message:

	Commit template file does not exist.

but in the C version the --template parameter gets ignored and
the default template is used.

t7500 has two tests for this case which would have caught it, except
that with the default $EDITOR, the commit message template is left
unmodified, causing 'git commit' to error out and the test to
succeed.

8e2dc6ac06 commit: give final warning when reattaching HEAD to leave commits behind
You can detach the HEAD at an arbitrary commit in order to browse the
files in various points in the history or build older versions of the
software, without recording any new commit, and come back to an existing
branch.  When used in this "sightseer" mode, detached HEAD is a perfectly
safe mechanism.  It also is a useful state to experiment with throw-away
commits.

When coming back to an existing branch with "git checkout master",
however, the commits that were created on the detached HEAD will become
unreachable from anywhere but the reflog of the HEAD.  Check if the commit
we are about to leave is connected to some ref, and give a final warning
otherwise to remind the user for safety.

b09c53a3e3 Sanity-check config variable names
Sanity-check config variable names when adding and retrieving them.  As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.

This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

37f7a85793 Teach commit about CHERRY_PICK_HEAD
Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).

On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.

In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.

This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.

A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

(Also removed an unused include from revert.c)

d7e5c0cbfb Introduce CHERRY_PICK_HEAD
When a cherry-pick conflicts git advises:

 $ git commit -c <original commit id>

to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:

  $ git commit -c CHERRY_PICK_HEAD

A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

a902618792 clone: die when trying to clone missing local path
Since 86ac751 (Allow cloning an empty repository,
2009-01-23), doing:

  git clone does-not-exist

has created does-not-exist as an empty repository. This was
an unintentional side effect of 86ac751. Even weirder,
doing:

  git clone does-not-exist new-dir

_does_ fail, making this "feature" (if you want to consider
it such) broken. Let's detect this situation and explicitly
die. It's almost certainly not what the user intended.

This patch also adds two tests. One for the missing path
case, and one to confirm that a similar case, cloning a
non-repository directory, fails.

ac49f5ca84 rerere "remaining"
After "rerere" resolves conflicts by reusing old resolution, there would
be three kinds of paths with conflict in the index:

 * paths that have been resolved in the working tree by rerere;
 * paths that need further work whose resolution could be recorded;
 * paths that need resolving that rerere won't help.

When the user wants a list of paths that need hand-resolving, output from
"rerere status" does not help, as it shows only the second category, but
the paths in the third category still needs work (rerere only makes sense
for regular files that have both our side and their side, and does not
help other kinds of conflicts, e.g. "we modified, they deleted").

The new subcommand "rerere remaining" can be used to show both. As
opposed to "rerere status", this subcommand also skips printing paths
that have been added to the index, since these paths are already
resolved and are no longer "remaining".

Initial patch provided by Junio. Refactored and modified to skip
resolved paths by Martin. Commit message mostly by Junio.

53c403116a push.default: Rename 'tracking' to 'upstream'
Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).

When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.

In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.

push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

dab0d4108d correct type of EMPTY_TREE_SHA1_BIN
Functions such as hashcmp that expect a binary SHA-1 value take
parameters of type "unsigned char *" to avoid accepting a textual
SHA-1 passed by mistake.  Unfortunately, this means passing the string
literal EMPTY_TREE_SHA1_BIN requires an ugly cast.  Tweak the
definition of EMPTY_TREE_SHA1_BIN to produce a value of more
convenient type.

In the future the definition might change to

	extern const unsigned char empty_tree_sha1_bin[20];
	#define EMPTY_TREE_SHA1_BIN empty_tree_sha1_bin

"git diff --cached" (without revision) used to mean "git diff --cached
HEAD" (i.e. the user was too lazy to type HEAD). This "correctly"
failed when there was no commit yet. But was that correctness useful?

This patch changes the definition of what particular command means.
It is a request to show what _would_ be committed without further "git
add". The internal implementation is the same "git diff --cached HEAD"
when HEAD exists, but when there is no commit yet, it compares the index
with an empty tree object to achieve the desired result.

ea6f0a23ac fsck: do not give up too early in fsck_dir()
When there is a random garbage file whose name happens to be 38-byte
long in a .git/objects/??/ directory, the loop terminated prematurely
without marking all the other files that it hasn't checked in the
readdir() loop.

Treat such a file just like any other garbage file, and do not break out
of the readdir() loop.

While at it, replace repeated sprintf() calls to a single one outside the
loop.

60a2e3320f remote-ext: do not segfault for blank lines
Instead of stripping space characters past the beginning of the
line and overflowing a buffer, stop at the beginning of the line
(mimicking the corresponding fix in remote-fd).

The argument to isspace does not need to be cast explicitly because
git isspace takes care of that already.

0cb6ad3c3d checkout: fix bug with ambiguous refs
The usual dwim_ref lookup prefers tags to branches. Because
checkout primarily works on branches, though, we switch that
behavior to prefer branches.

However, there was a bug in the implementation in which we
used lookup_commit_reference (which used the regular lookup
rules) to get the actual commit to checkout. Checking out an
ambiguous ref therefore ended up putting us in an extremely
broken state in which we wrote the branch ref into HEAD, but
actually checked out the tree for the tag.

This patch fixes the bug by always attempting to pull the
commit to be checked out from the branch-ified version of
the name we were given.

Patch by Junio, tests and commit message from Jeff King.

For example, this would allow cherry-picking or reverting patches from
a piece of history with a different end-of-line style, like so:

	$ git revert -Xrenormalize old-problematic-commit

Currently that is possible with manual use of merge-recursive but the
cherry-pick/revert porcelain does not expose the functionality.

While at it, document the existing support for --strategy.

e6aea2dba2 setup: limit get_git_work_tree()'s to explicit setup case only
get_git_work_tree() takes input as core.worktree, core.bare,
GIT_WORK_TREE and decides correct worktree setting.

Unfortunately it does not do its job well. core.worktree and
GIT_WORK_TREE should only be taken into account, if GIT_DIR is set
(which is handled by setup_explicit_git_dir). For other setup cases,
only core.bare matters.

Add a temporary variable setup_explicit to adjust get_git_work_tree()
behavior as such. This variable will be gone once setup_* rework is
done.

Also remove is_bare_repository_cfg check in set_git_work_tree() to
ease the rework. We are going to check for core.bare and core.worktree
early before setting worktree. For example, if core.bare is true, no
need to set worktree.

4c28e4ada0 commit: die before asking to edit the log message
When determine_author_info() returns to the calling prepare_to_commit(),
we already know the pieces of information necessary to determine what
author ident will be used in the final message, but deferred making a call
to fmt_ident() before the final commit_tree().  Most importantly, we would
open the editor to ask the user to compose the log message before it.

As one important side effect of fmt_ident() is to error out when the given
information is malformed, this resulted in us spawning the editor first
and then refusing to commit due to error, even though we had enough
information to detect the error before starting the editor, which was
annoying.

Move the fmt_ident() call to the end of determine_author_info() where we
have final determination of author info to rectify this.

d1645d02de describe: Delay looking up commits until searching for an inexact match
Now that struct commit.util is not used until after we've checked that
the argument doesn't exactly match a tag, we can wait until then to
look up the commits for each tag.

This avoids a lot of I/O on --exact-match queries in repositories with
many tags.  For example, 'git describe --exact-match HEAD' becomes
about 12 times faster on a cold cache (3.2s instead of 39s) in a
linux-2.6 repository with 2000 packed tags.  That is a huge win for the
interactivity of the __git_ps1 shell prompt helper when on a detached
HEAD.

describe is currently forced to look up the commit at each tag in
order to store the struct commit_name pointers in struct commit.util.
For --exact-match queries, those lookups are wasteful.  In preparation

commit SHA1, that can be used to quickly check for exact matches.

309be813c9 update-index: migrate to parse-options API
--refresh and --really-refresh accept flags (like -q) and modify
an error indicator.  It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.

--cacheinfo wants 3 arguments.  Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form.  (The resulting message

	$ git update-index --cacheinfo=foo
	error: option `cacheinfo' takes no value

is unfortunately incorrect.)

--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.

--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).

--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).

The order of options matters.  Each path on the command line is
affected only by the options that come before it.  A custom
argument-parsing loop with parse_options_step() brings that about.

In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.

Pass output through the pager if format-patch is run with --stdout. This
saves the user the trouble of running git with '-p' or piping through a

setup_pager() already checks if stdout is a tty, so we don't have to

35d2fffdb8 Provide 'git merge --abort' as a synonym to 'git reset --merge'
Teach 'git merge' the --abort option, which verifies the existence of
MERGE_HEAD and then invokes 'git reset --merge' to abort the current
in-progress merge and attempt to reconstruct the pre-merge state.

The reason for adding this option is to provide a user interface for
aborting an in-progress merge that is consistent with the interface
for aborting a rebase ('git rebase --abort'), aborting the application
of a patch series ('git am --abort'), and aborting an in-progress notes
merge ('git notes merge --abort').

The patch includes documentation and testcases that explain and verify
the various scenarios in which 'git merge --abort' can run. The
testcases also document the cases in which 'git merge --abort' is
unable to correctly restore the pre-merge state (look for the '###'
comments towards the bottom of t/t7609-merge-abort.sh).

a6a09095a0 git notes merge: Add another auto-resolving strategy: "cat_sort_uniq"
This new strategy is similar to "concatenate", but in addition to
concatenating the two note candidates, this strategy sorts the resulting
lines, and removes duplicate lines from the result. This is equivalent to
applying the "cat | sort | uniq" shell pipeline to the two note candidates.

This strategy is useful if the notes follow a line-based format where one
wants to avoid duplicate lines in the merge result.

Note that if either of the note candidates contain duplicate lines _prior_
to the merge, these will also be removed by this merge strategy.

The patch also contains tests and documentation for the new strategy.

6cfd6a9dea git notes merge: --commit should fail if underlying notes ref has moved
When manually resolving a notes merge, if the merging ref has moved since
the merge started, we should fail to complete the merge, and alert the user
to what's going on.

This situation may arise if you start a 'git notes merge' which results in
conflicts, and you then update the current notes ref (using for example
'git notes add/copy/amend/edit/remove/prune', 'git update-ref', etc.),
before you get around to resolving the notes conflicts and calling
'git notes merge --commit'.

We detect this situation by comparing the first parent of the partial merge
commit (which was created when the merge started) to the current value of the
merging notes ref (pointed to by the .git/NOTES_MERGE_REF symref).

If we don't fail in this situation, the notes merge commit would overwrite
the updated notes ref, thus losing the changes that happened in the meantime.

The patch includes a testcase verifying that we fail correctly in this
situation.

6abb3655ef git notes merge: Manual conflict resolution, part 2/2
When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been
resolved, we need to record a new notes commit on the appropriate notes
ref with the resolved notes.

This patch implements 'git notes merge --commit' which the user should
run after resolving conflicts in the notes merge worktree. This command
finalizes the notes merge by recombining the partial notes tree from
part 1 with the now-resolved conflicts in the notes merge worktree in a
merge commit, and updating the appropriate ref to this merge commit.

In order to correctly finalize the merge, we need to keep track of three
things:

- The partial merge result from part 1, containing the auto-merged notes.
  This is now stored into a ref called .git/NOTES_MERGE_PARTIAL.
- The unmerged notes. These are already stored in
  .git/NOTES_MERGE_WORKTREE, thanks to part 1.
- The notes ref to be updated by the finalized merge result. This is now
  stored in a symref called .git/NOTES_MERGE_REF.

In addition to "git notes merge --commit", which uses the above details
to create the finalized notes merge commit, this patch also implements
"git notes merge --reset", which aborts the ongoing notes merge by simply
removing the files/directory described above.

FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove
the information described above (.git/NOTES_MERGE_*) after the notes merge
have been successfully finalized.

The patch also contains documentation and testcases for the two new options.

This patch has been improved by the following contributions:
- Ævar Arnfjörð Bjarmason: Fix nonsense sentence in --commit description
- Sverre Rabbelier: Rename --reset to --abort

809f38c8ab git notes merge: Manual conflict resolution, part 1/2
Conflicts (that are to be resolved manually) are written into a special-
purpose working tree, located at .git/NOTES_MERGE_WORKTREE. Within this
directory, conflicting notes entries are stored (with conflict markers
produced by ll_merge()) using the SHA1 of the annotated object. The
.git/NOTES_MERGE_WORKTREE directory will only contain the _conflicting_
note entries. The non-conflicting note entries (aka. the partial merge
result) are stored in 'local_tree', and the SHA1 of the resulting commit
is written to 'result_sha1'. The return value from notes_merge() is -1.

The user is told to edit the files within the .git/NOTES_MERGE_WORKTREE
directory in order to resolve the conflicts.

The patch also contains documentation and testcases for the correct setup
of .git/NOTES_MERGE_WORKTREE.

The next part will recombine the partial notes merge result with the
resolved conflicts in .git/NOTES_MERGE_WORKTREE to produce the complete
merge result.

3228e67120 git notes merge: Add automatic conflict resolvers (ours, theirs, union)
The new -s/--strategy command-line option to 'git notes merge' allow the user
to choose how notes merge conflicts should be resolved. There are four valid
strategies to choose from:

1. "manual" (the default): This will let the user manually resolve conflicts.
   This option currently fails with an error message. It will be implemented
   properly in future patches.

2. "ours": This automatically chooses the local version of a conflict, and
   discards the remote version.

3. "theirs": This automatically chooses the remote version of a conflict, and
   discards the local version.

4. "union": This automatically resolves the conflict by appending the remote
   version to the local version.

The strategies are implemented using the combine_notes_* functions from the
notes.h API.

The patch also includes testcases verifying the correct implementation of
these strategies.

This patch has been improved by the following contributions:
- Jonathan Nieder: Future-proof by always checking add_note() return value

2085b16aef git notes merge: Handle real, non-conflicting notes merges
This continuation of the 'git notes merge' implementation teaches notes-merge
to properly do real merges between notes trees: Two diffs are performed, one
from $base to $remote, and another from $base to $local. The paths in each
diff are normalized to SHA1 object names. The two diffs are then consolidated
into a single list of change pairs to be evaluated. Each change pair consist
of:

  - The annotated object's SHA1
  - The $base SHA1 (i.e. the common ancestor notes for this object)
  - The $local SHA1 (i.e. the current notes for this object)
  - The $remote SHA1 (i.e. the to-be-merged notes for this object)

From the pair ($base -> $local, $base -> $remote), we can determine the merge
result using regular 3-way rules. If conflicts are encountered in this
process, we fail loudly and exit (conflict handling to be added in a future
patch), If we can complete the merge without conflicts, the resulting
notes tree is committed, and the current notes ref updated.

The patch includes added testcases verifying that we can successfully do real
conflict-less merges.

- Jonathan Nieder: Future-proof by always checking add_note() return value

180619a585 notes.h/c: Propagate combine_notes_fn return value to add_note() and beyond
The combine_notes_fn functions uses a non-zero return value to indicate
failure. However, this return value was converted to a call to die()
in note_tree_insert().

Instead, propagate this return value out to add_note(), and return it
from there to enable the caller to handle errors appropriately.

Existing add_note() callers are updated to die() upon failure, thus
preserving the current behaviour. The only exceptions are copy_note()
and notes_cache_put() where we are able to propagate the add_note()
return value instead.

172b6428d0 do not overwrite untracked during merge from unborn branch
In case HEAD does not point to a valid commit yet, merge is
implemented as a hard reset. This will cause untracked files to be
overwritten.

Instead, assume the empty tree for HEAD and do a regular merge. An
untracked file will cause the merge to abort and do nothing. If no
conflicting files are present, the merge will have the same effect
as a hard reset.

0188f6b3c1 add: do not rely on dtype being NULL behavior
Commit c84de70 (excluded_1(): support exclude files in index -
2009-08-20) added support for excluded() where dtype can be NULL. It
was designed specifically for index matching because there was no
other way to extract dtype information from index. It did not support
wildcard matching (for example, "a*/" pattern would fail to match).

The code was probably misread when commit 108da0d (git add: Add the
"--ignore-missing" option for the dry run - 2010-07-10) was made
because DT_UNKNOWN happens to be zero (NULL) too.

Do not pass DT_UNKNOWN/NULL to excluded(), instead pass a pointer to a
variable that contains DT_UNKNOWN. The real dtype will be extracted
from worktree by excluded(), as expected.

7dce19d374 fetch/pull: Add the --recurse-submodules option
Until now you had to call "git submodule update" (without -N|--no-fetch
option) or something like "git submodule foreach git fetch" to fetch
new commits in populated submodules from their remote.

This could lead to "(commits not present)" messages in the output of
"git diff --submodule" (which is used by "git gui" and "gitk") after
fetching or pulling new commits in the superproject and is an obstacle for
implementing recursive checkout of submodules. Also "git submodule
update" cannot fetch changes when disconnected, so it was very easy to
forget to fetch the submodule changes before disconnecting only to
discover later that they are needed.

This patch adds the "--recurse-submodules" option to recursively fetch
each populated submodule from the url configured in the .git/config of the
submodule at the end of each "git fetch" or during "git pull" in the
superproject. The submodule paths are taken from the index.

The hidden option "--submodule-prefix" is added to "git fetch" to be able
to print out the full paths of nested submodules.

24305cd700 apply: don't segfault on binary files with missing data
Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.

However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).

If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.

We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

64f003abd9 send-pack: avoid redundant "pack-objects died with strange error"
Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant.  The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).

Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.

So leave off the "strange error" messages.

The result should look something like this:

	$ git push sf master
	Counting objects: 21542, done.
	Compressing objects: 100% (4179/4179), done.
	fatal: Unable to create temporary file: Permission denied
	error: pack-objects died of signal 13
	error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
	$

Or in the "controlled exit" case (contrived example):

	[...]
	fatal: delta size changed
	error: failed to push some refs to 'ssh://example.com/foo/bar'
	$

This buffer is freed by the C runtime when commit-tree exits moments

c03c83152d do not depend on signed integer overflow
Signed integer overflow is not defined in C, so do not depend on it.

This fixes a problem with GCC 4.4.0 and -O3 where the optimizer would
consider "consumed_bytes > consumed_bytes + bytes" as a constant
expression, and never execute the die()-call.

9173912be3 init: plug tiny one-time memory leak
The buffer used to construct paths like ".git/objects/info" and
".git/objects/pack" is allocated on the heap and never freed.

So free it.  While at it, factor out the relevant code into its own
function and rename the sha1_dir variable to object_directory (to
match the change in everyday usage after the renaming of
SHA1_FILE_DIRECTORY in v0.99~603^2~7, 2005).

Noticed by valgrind while setting up tests (in test-lib).

6355e505ba builtin/revert.c: don't dereference a NULL pointer
cherry-pick will segfault when transplanting a root commit if the --ff
option is used.  This happens because the "parent" pointer is set to NULL
when the commit being cherry-picked has no parents.  Later, when "parent"
is dereferenced, the cherry-pick segfaults.

Fix this by checking whether "parent" is NULL before dereferencing it and
add a test for this case of cherry-picking a root commit with --ff.

Currently, read-tree can be run without tree-ish arguments, in which
case it will empty the index. Since this behavior is undocumented and
perhaps a bit too invasive to be the "default" action for read-tree,
deprecate it in favor of a new --empty option that does the same thing.

In the updated API, shortlog_len == 0 means no shortlog is given.

The parameter "merge_title" controls if the title of the merge commit is
autogenerated (it reads something like "Merge branch ..."), and typically
it is set to true when the caller does not give its own message.

4ce6fb8058 fast-export: ensure that a renamed file is printed after all references
t9350 sets up a commit where a file is both copied and renamed. The output
of fast-export for this commit should look like this:

  author ...
  committer ...
  from :19
  C "file2" "file4"
  R "file2" "file5"

The order of the two modification lines is derived from the result that
the diff machinery produces.

060df62 (fast-export: Fix output order of D/F changes) inserted a qsort
call that modifies the order of the diff result. Unfortunately, qsort need
not be stable. Therefore, it is possible that the 'R' line appears before
the 'C' line and the resulting fast-import stream is incorrect.

Fix it by forcing that the rename entry is printed after all other
modification lines with the same file name.

e78d01bf4e builtin/merge_recursive.c: Add an usage string and make use of it.
This improves the usage output by adding builtin_merge_recursive_usage string
that follows the same pattern used by the other builtin commands.

The previous output for git merger-recursive was:
usage: merge-recursive <base>... -- <head> <remote> ...

Now the output is:
usage: git merge-recursive <base>... -- <head> <remote> ...

Since cmd_merge_recursive is used to handle four different commands we need
the %s in the usage string, so the following example:

$ git merge-subtree -h

Will output:
usage: git merge-subtree <base>... -- <head> <remote> ...

5e65ee35dd Move "show_all_errors = 1" to setup_unpack_trees_porcelain()
Not only this makes the code clearer since setting up the porcelain error
message is meant to work with show_all_errors, but this fixes a call to
setup_unpack_trees_porcelain() in git_merge_trees() which did not set
show_all_errors.

add_rejected_path() used to double-check whether it was running in
plumbing mode. This check was ineffective since it was setting
show_all_errors too late for traverse_trees() to see it, and is made
useless by this patch. Remove it.
