5a2df368c2 config: Give error message when not changing a multivar
When trying to set a multivar with "git config var value", "git config"
issues

warning: remote.repoor.push has multiple values

leaving the user under the impression that the operation succeeded,
unless one checks the return value.

Instead, make it

warning: remote.repoor.push has multiple values
error: cannot overwrite multiple values with a single value
       Use a regexp, --add or --set-all to change remote.repoor.push.

to be clear and helpful.

Note: The "warning" is raised through other code paths also so that it
needs to remain a warning for these (which do not raise the error). Only
the caller can determine how to go on from that.

fad2652673 revert: allow reverting a root commit
Although it is probably an uncommon operation, there is no
reason to disallow it, as it works just fine. It is the
reverse of a cherry-pick of a root commit, which is already
allowed.

We do have to tweak one check on whether we have a merge
commit, which assumed we had at least one parent.

161807349a cherry-pick: handle root commits with external strategies
The merge-recursive strategy already handles root commits;
it cherry-picks the difference between the empty tree and
the root commit's tree.

However, for external strategies, we dereference NULL and
segfault while building the argument list. Instead, let's
handle this by passing the empty tree sha1 to the merge
script.

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]'".

258a618849 git-grep: Bail out when -P is used with -F or -E
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`.

63e7e9d8b6 git-grep: Learn PCRE
This patch teaches git-grep the --perl-regexp/-P options (naming
borrowed from GNU grep) in order to allow specifying PCRE regexes on the
command line.

PCRE has a number of features which make them more handy to use than
POSIX regexes, like consistent escaping rules, extended character
classes, ungreedy matching etc.

git isn't build with PCRE support automatically. USE_LIBPCRE environment
variable must be enabled (like `make USE_LIBPCRE=YesPlease`).

e86226e340 blame: refactor porcelain output
This is in preparation for adding more porcelain output
options. The three changes are:

  1. emit_porcelain now receives the format option flags

  2. emit_one_suspect_detail takes an optional "repeat"
     parameter to suppress the "show only once" behavior

  3. The code for emitting porcelain suspect is factored
     into its own function for repeatability.

There should be no functional changes.

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.

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 */

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

    933a615 commit subject 1
    824fcde commit subject 2

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.

6e0332ec3e branch: split off function that writes tracking info and commit subject
Introduce a add_verbose_info function that takes care of adding

 - an abbreviated object name;
 - a summary of the form [ahead x, behind y] of the relationship
   to the corresponding upstream branch;
 - a one line commit subject

for the tip commit of a branch, for use in "git branch -v" output.

No functional change intended.  This just unindents the code a little
and makes it easier to skip on first reading.

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_]* {$' yields about 5 times as many
matches as 'struct [a-z_]*$'.

Linus sayeth:

 Heretic people all over the world have claimed that this inconsistency
 is ...  well ...  inconsistent, but all right-thinking people know that
 (a) K&R are _right_ and (b) K&R are right.

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.
