97f261b1e7 builtin/init-db.c: eliminate -Wformat warning on Solaris
On Solaris systems we'd warn about an implicit cast of mode_t when we
printed things out with the %d format. We'd get this warning under GCC
4.6.0 with Solaris headers:

    builtin/init-db.c: In function ‘separate_git_dir’:
    builtin/init-db.c:354:4: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘mode_t’ [-Wformat]

We've been doing this ever since v1.7.4.1-296-gb57fb80. Just work
around this by adding an explicit cast.

b13e3eacef gitweb: Fix fallback mode of to_utf8 subroutine
e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding.,
2007-12-04) was meant to make gitweb faster by using Perl's internals
(see subsection "Messing with Perl's Internals" in Encode(3pm) manpage)

Simple benchmark confirms that (old = 00f429a, new = this version):

        old  new
  old    -- -65%
  new  189%   --

Unfortunately it made fallback mode of to_utf8 do not work...  except
for default value 'latin1' of $fallback_encoding ('latin1' is Perl
native encoding), which is why it was not noticed for such long time.

utf8::valid(STRING) is an internal function that tests whether STRING
is in a _consistent state_ regarding UTF-8.  It returns true is
well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held
as bytes (both these states are 'consistent').  For gitweb the second
option was true, as output from git commands is opened without ':utf8'
layer.

What made it work at all for STRING in 'latin1' encoding is the fact
that utf8:decode(STRING) turns on UTF-8 flag only if source string is
valid UTF-8 and contains multi-byte UTF-8 characters... and that if
string doesn't have UTF-8 flag set it is treated as in native Perl
encoding, i.e.  'latin1' / 'iso-8859-1' (unless native encoding it is
EBCDIC ;-)).  It was ':utf8' layer that actually converted 'latin1'
(no UTF-8 flag == native == 'latin1) to 'utf8'.

Let's make use of the fact that utf8:decode(STRING) returns false if
STRING is invalid as UTF-8 to check whether to enable fallback mode.

02f7914734 remote-curl: don't pass back fake refs
When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.

However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.

On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.

However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref).  But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.

Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.

Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).

This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

8496f56873 lf_to_crlf_filter(): resurrect CRLF->CRLF hack
The non-streaming version of the filter counts CRLF and LF in the whole
buffer, and returns without doing anything when they match (i.e. what is
recorded in the object store already uses CRLF). This was done to help
people who added files from the DOS world before realizing they want to go
cross platform and adding .gitattributes to tell Git that they only want
CRLF in their working tree.

The streaming version of the filter does not want to read the whole thing
before starting to work, as that defeats the whole point of streaming. So
we instead check what byte follows CR whenever we see one, and add CR
before LF only when the LF does not immediately follow CR already to keep
CRLF as is.

bd2c86ef00 make "git push -v" actually verbose
Providing a single "-v" to "git push" currently does
nothing. Giving two flags ("git push -v -v") turns on the
first level of verbosity.

This is caused by a regression introduced in 8afd8dc (push:
support multiple levels of verbosity, 2010-02-24). Before
the series containing 8afd8dc, the verbosity handling for
fetching and pushing was completely separate. Commit bde873c
refactored the verbosity handling out of the fetch side, and
then 8afd8dc converted push to use the refactored code.

However, the fetch and push sides numbered and passed along
their verbosity levels differently. For both, a verbosity
level of "-1" meant "quiet", and "0" meant "default output".
But from there they differed.

For fetch, a verbosity level of "1" indicated to the "fetch"
program that it should make the status table slightly more
verbose, showing up-to-date entries. A verbosity level of
"2" meant that we should pass a verbose flag to the
transport; in the case of fetch-pack, this displays protocol
debugging information.

As a result, the refactored code in bde873c checks for
"verbosity >= 2", and only then passes it on to the
transport. From the transport code's perspective, a
verbosity of 0 or 1 both meant "0".

Push, on the other hand, does not show its own status table;
that is always handled by the transport layer or below
(originally send-pack itself, but these days it is done by
the transport code). So a verbosity level of 1 meant that we
should pass the verbose flag to send-pack, so that it knows
we want a verbose status table. However, once 8afd8dc
switched it to the refactored fetch code, a verbosity level
of 1 was now being ignored.  Thus, you needed to
artificially bump the verbosity to 2 (via "-v -v") to have
any effect.

We can fix this by letting the transport code know about the
true verbosity level (i.e., let it distinguish level 0 or
1).

We then have to also make an adjustment to any transport
methods that assumed "verbose > 0" meant they could spew
lots of debugging information. Before, they could only get
"0" or "2", but now they will also receive "1". They need to
adjust their condition for turning on such spew from
"verbose > 0" to "verbose > 1".

2830308260 docs: brush up obsolete bits of git-fsck manpage
After the description and options, the fsck manpage contains
some discussion about what it does. Over time, this
discussion has become somewhat obsolete, both in content and
formatting. In particular:

  1. There are many options now, so starting the discussion
     with "It tests..." makes it unclear whether we are
     talking about the last option, or about the tool in
     general. Let's start a new "discussion" section and
     make our antecedent more clear.

  2. It gave an example for --unreachable using for-each-ref
     to mention all of the heads, saying that it will do "a
     _lot_ of verification". This is hopelessly out-of-date,
     as giving no arguments will check much more (reflogs,
     the index, non-head refs).

  3. It goes on to mention tests "to be added" (like tree
     object sorting). We now have these tests.

dd98d88be7 use custom rename score during --follow
If you provide a custom rename score on the command line,
like:

  git log -M50 --follow foo.c

it is completely ignored, and there is no way to --follow
with a looser rename score. Instead, let's use the same
rename score that will be used for generating diffs. This is
convenient, and mirrors what we do with the break-score.

You can see an example of it being useful in git.git:

  $ git log --oneline --summary --follow \
	    Documentation/technical/api-string-list.txt
  86d4b52 string-list: Add API to remove an item from an unsorted list

  c455c87 Rename path_list to string_list
   create mode 100644 Documentation/technical/api-string-list.txt

  $ git log --oneline --summary -M40 --follow \
	  Documentation/technical/api-string-list.txt
  86d4b52 string-list: Add API to remove an item from an unsorted list
  1d2f80f string_list: Fix argument order for string_list_append
  e242148 string-list: add unsorted_string_list_lookup()
  0dda1d1 Fix two leftovers from path_list->string_list

  328a475 path-list documentation: document all functions and data structures
  530e741 Start preparing the API documents.
   create mode 100644 Documentation/technical/api-path-list.txt

You could have two separate rename scores, one for following
and one for diff. But almost nobody is going to want that,
and it would just be unnecessarily confusing. Besides which,
we re-use the diff results from try_to_follow_renames for
the actual diff output, which means having them as separate
scores is actively wrong. E.g., with the current code, you
get:

  $ git log --oneline --diff-filter=R --name-status \
            -M90 --follow git.spec.in
  27dedf0 GIT 0.99.9j aka 1.0rc3
  R084    git-core.spec.in        git.spec.in
  f85639c Rename the RPM from "git" to "git-core"
  R098    git.spec.in     git-core.spec.in

The first one should not be considered a rename by the -M
score we gave, but we print it anyway, since we blindly
re-use the diff information from the follow (which uses the
default score). So this could also be considered simply a
bug-fix, as with the current code "-M" is completely ignored
when using "--follow".

a4ddbc33d7 http-push: enable "proactive auth"
Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.

However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).

Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and
smart-http as-is.

0521710a8b t5540: test DAV push with authentication
We don't currently test this case at all, and instead just
test the DAV mechanism over an unauthenticated push. That
isn't very realistic, as most people will want to
authenticate pushes.

Two of the tests expect_failure as they reveal bugs:

  1. Pushing without a username in the URL fails to ask for
     credentials when we get an HTTP 401. This has always
     been the case, but it would be nice if it worked like
     smart-http.

  2. Pushing with a username fails to ask for the password
     since 986bbc0 (http: don't always prompt for password,
     2011-11-04). This is a severe regression in v1.7.8, as
     authenticated push-over-DAV is now totally unusable
     unless you have credentials in your .netrc.

the remote side, and a "match" list of things we want to
fetch. We iterate through the remote refs alphabetically,
seeing if each one is wanted by the "match" list.

Since def88e9 (Commit first cut at "git-fetch-pack",
2005-07-04), we have used the "path_match" function to do a
suffix match, where a remote ref is considered wanted if
any of the "match" elements is a suffix of the remote
refname.

This enables callers of fetch-pack to specify unqualified
refs and have them matched up with remote refs (e.g., ask
for "A" and get remote's "refs/heads/A"). However, if you
provide a fully qualified ref, then there are corner cases
where we provide the wrong answer. For example, given a
remote with two refs:

   refs/foo/refs/heads/master
   refs/heads/master

asking for "refs/heads/master" will first match
"refs/foo/refs/heads/master" by the suffix rule, and we will
erroneously fetch it instead of refs/heads/master.

As it turns out, all callers of fetch_pack do provide
fully-qualified refs for the match list. There are two ways
fetch_pack can get match lists:

  1. Through the transport code (i.e., via git-fetch)

  2. On the command-line of git-fetch-pack

In the first case, we will always be providing the names of
fully-qualified refs from "struct ref" objects. We will have
pre-matched those ref objects already (since we have to
handle more advanced matching, like wildcard refspecs), and
are just providing a list of the refs whose objects we need.

In the second case, users could in theory be providing
non-qualified refs on the command-line. However, the
fetch-pack documentation claims that refs should be fully
qualified (and has always done so since it was written in
2005).

Let's change this path_match call to simply check for string
equality, matching what the callers of fetch_pack are
expecting.

e9d866e32c t5500: give fully-qualified refs to fetch-pack
The fetch-pack documentation is very clear that refs given
on the command line are to be full refs:

  <refs>...::
          The remote heads to update from. This is relative to
          $GIT_DIR (e.g. "HEAD", "refs/heads/master").  When
          unspecified, update from all heads the remote side has.

and this has been the case since fetch-pack was originally documented in
8b3d9dc ([PATCH] Documentation: clone/fetch/upload., 2005-07-14).

Let's follow our own documentation to set a good example,
and to avoid breaking when this restriction is enforced in
the next patch.

afe7c5ff1f drop "match" parameter from get_remote_heads
The get_remote_heads function reads the list of remote refs
during git protocol session. It dates all the way back to
def88e9 (Commit first cut at "git-fetch-pack", 2005-07-04).
At that time, the idea was to come up with a list of refs we
were interested in, and then filter the list as we got it
from the remote side.

Later, 1baaae5 (Make maximal use of the remote refs,
2005-10-28) stopped filtering at the get_remote_heads layer,
letting us use the non-matching refs to find common history.

As a result, all callers now simply pass an empty match
list (and any future callers will want to do the same). So
let's drop these now-useless parameters.

534376ca04 mv: be quiet about overwriting
When a user asks us to force a mv and overwrite the
destination, we print a warning. However, since a typical
use would be:

  $ git mv one two
  fatal: destination exists, source=one, destination=two
  $ git mv -f one two
  warning: overwriting 'two'

this warning is just noise. We already know we're
overwriting; that's why we gave -f!

This patch silences the warning unless "--verbose" is given.

cd40b05d13 mv: improve overwrite warning
When we try to "git mv" over an existing file, the error
message is fairly informative:

  $ git mv one two
  fatal: destination exists, source=one, destination=two

When the user forces the overwrite, we give a warning:

  $ git mv -f one two
  warning: destination exists; will overwrite!

This is less informative, but still sufficient in the simple
rename case, as there is only one rename happening.

But when moving files from one directory to another, it
becomes useless:

  $ mkdir three
  $ touch one two three/one
  $ git add .
  $ git mv one two three
  fatal: destination exists, source=one, destination=three/one
  $ git mv -f one two three
  warning: destination exists; will overwrite!

The first message is helpful, but the second one gives us no
clue about what was overwritten. Let's mention the name of
the destination file:

  $ git mv -f one two three
  warning: overwriting 'three/one'

Now that "git reset" no longer implicitly removes .git/sequencer that
the operator may or may not have wanted to keep, the logic to write a
backup copy of .git/sequencer and remove it when stale is not needed
any more.  Simplify the sequencer API and repository layout by
dropping it.

218b65fbf9 revert: do not remove state until sequence is finished
As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch.  In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:

	git cherry-pick foo
	git read-tree -m -u HEAD; # forget that; let's try a different one
	git cherry-pick bar

After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more.  In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.

So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

After messing up a difficult conflict resolution in the middle of a
cherry-pick sequence, it can be useful to be able to

	git checkout HEAD . && git cherry-pick that-one-commit

to restart the conflict resolution. The current code however errors out
saying that another cherry-pick is already in progress.

7f13334e07 revert: pass around rev-list args in already-parsed form
Since 7e2bfd3f (revert: allow cherry-picking more than one commit,
2010-07-02), the pick/revert machinery has kept track of the set of
commits to be cherry-picked or reverted using commit_argc and
commit_argv variables, storing the corresponding command-line
parameters.

Future callers as other commands are built in (am, rebase, sequencer)
may find it easier to pass rev-list options to this machinery in
already-parsed form.  Teach cmd_cherry_pick and cmd_revert to parse
the rev-list arguments in advance and pass the commit set to
pick_revisions() as a rev_info structure.

093a309136 revert: allow cherry-pick --continue to commit before resuming
When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.

This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.

Example: after encountering a conflict from running "git cherry-pick
foo bar baz":

	CONFLICT (content): Merge conflict in main.c
	error: could not apply f78a8d98c... bar!
	hint: after resolving the conflicts, mark the corrected paths
	hint: with 'git add <paths>' or 'git rm <paths>'
	hint: and commit the result with 'git commit'

We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.

	$ git cherry-pick --continue
	[editor opens to confirm commit message]
	[master 78c8a8c98] bar!
	 1 files changed, 1 insertions(+), 1 deletions(-)
	[master 87ca8798c] baz!
	 1 files changed, 1 insertions(+), 1 deletions(-)

This is done for both codepaths to pick multiple commits and a single
commit.
