723f7a1387 daemon: return "access denied" if a service is not allowed
The message is chosen to avoid leaking information, yet let users know
that they are deliberately not allowed to use the service, not a fault
in service configuration or the service itself.

0b20dd8f3d Makefile: do not set setgid bit on directories on GNU/kFreeBSD
The g+s bit on directories to make group ownership inherited is a
SysVism --- BSD and most of its descendants do not need it since they
do the sane thing by default without g+s.  In fact, on some
filesystems (but not all --- tmpfs works this way but UFS does not),
the kernel of FreeBSD does not even allow non-root users to set setgid
bit on directories and produces errors when one tries:

	$ git init --shared dir
	fatal: Could not make /tmp/dir/.git/refs writable by group

Since the setgid bit would only mean "do what you were going to do
already", it's better to avoid setting it.  Accordingly, ever since
v1.5.5-rc0~59^2 (Do not use GUID on dir in git init --share=all on
FreeBSD, 2008-03-05), git on true FreeBSD has done exactly that.  Set
DIR_HAS_BSD_GROUP_SEMANTICS in the makefile for GNU/kFreeBSD, too, so
machines that use glibc with the kernel of FreeBSD get the same fix.

This fixes t0001-init.sh and t1301-shared-repo.sh on GNU/kFreeBSD
when running tests with --root pointing to a directory that uses
tmpfs.

8a55caa8a3 ident: check /etc/mailname if email is unknown
Before falling back to gethostname(), check /etc/mailname if
GIT_AUTHOR_EMAIL is not set in the environment or through config
files.  Only fall back if /etc/mailname cannot be opened or read.

The /etc/mailname convention comes from Debian policy section 11.6
("mail transport, delivery and user agents"), though maybe it could be
useful sometimes on other machines, too.  The lack of this support was
noticed by various people in different ways:

 - Ian observed that git was choosing the address
   'ian@anarres.relativity.greenend.org.uk' rather than
   'ian@davenant.greenend.org.uk' as it should have done.

 - Jonathan noticed that operations like "git commit" were needlessly
   slow when using a resolver that was slow to handle reverse DNS
   lookups.

Alas, after this patch, if /etc/mailname is set up and the [user] name
and email configuration aren't, the committer email will not provide a
charming reminder of which machine commits were made on any more.  But
I think it's worth it.

Mechanics: the functionality of reading mailname goes in its own
function, so people who care about other distros can easily add an
implementation to a similar location without making copy_email() too
long and losing clarity.  While at it, we split out the fallback
default logic that does gethostname(), too (rearranging it a little
and adding a check for errors from gethostname while at it).

Based on a patch by Gerrit Pape <pape@smarden.org>.

Instead of going through all the references again when we clear the

list of pending objects which we constructed from those references.

We simply copy the struct object_array that points to the list, set

it and it's ours.  We use it to clear the marks and  free it at the

4a43d374fc revision: add leak_pending flag
The new flag leak_pending in struct rev_info can be used to prevent
prepare_revision_walk from freeing the list of pending objects.  It
will still forget about them, so it really is leaked.  This behaviour
may look weird at first, but it can be useful if the pointer to the
list is saved before calling prepare_revision_walk.

e9c4c11165 refs: Use binary search to lookup refs faster
Currently we linearly search through lists of refs when we need to
find a specific ref.  This can be very slow if we need to lookup a
large number of refs.  By changing to a binary search we can make this
faster.

In order to be able to use a binary search we need to change from
using linked lists to arrays, which we can manage using ALLOC_GROW.

We can now also use the standard library qsort function to sort the
refs arrays.

160b81ed81 receive-pack: don't pass non-existent refs to post-{receive,update} hooks
When a push specifies deletion of non-existent refs, the post post-receive and
post-update hooks receive them as input/arguments.

For instance, for the following push, where refs/heads/nonexistent is a ref
which does not exist on the remote side:

	git push origin :refs/heads/nonexistent

the post-receive hook receives from standard input:

	<null-sha1> SP <null-sha1> SP refs/heads/nonexistent

and the post-update hook receives as arguments:

	refs/heads/nonexistent

which does not make sense since it is a no-op.

Teach receive-pack not to pass non-existent refs to the post-receive and
post-update hooks. If the push only attempts to delete non-existent refs,
these hooks are not even called.

The update and pre-receive hooks are still notified about attempted
deletion of non-existent refs to give them a chance to inspect the
situation and act on it.

[jc: mild fix-ups to avoid introducing an extra list; also added fixes to
some tests]

0a1283bc39 checkout $tree $path: do not clobber local changes in $path not in $tree
Checking paths out of a tree is (currently) defined to do:

 - Grab the paths from the named tree that match the given pathspec,
   and add them to the index;

 - Check out the contents from the index for paths that match the
   pathspec to the working tree; and while at it

 - If the given pathspec did not match anything, suspect a typo from the
   command line and error out without updating the index nor the working
   tree.

Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running

 $ git checkout other dir

would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.

Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

ccdbdc79a3 send-email: auth plain/login fix
git send-email was not authenticating properly when communicating over
TLS with a server supporting only AUTH PLAIN and AUTH LOGIN. This is
e.g. the standard server setup under debian with exim4 and probably
everywhere where system accounts are used.

The problem (only?) exists when libauthen-sasl-cyrus-perl
(Authen::SASL::Cyrus) is installed. Importing Authen::SASL::Perl
makes Authen::SASL use the perl implementation which works
better.

The solution is based on this forum thread:
http://www.perlmonks.org/?node_id=904354.

This patch is tested by sending it. Without this fix, the interaction with
the server failed like this:

$ git send-email --smtp-encryption=tls --smtp-server=... --smtp-debug=1 change1.patch
...
Net::SMTP::SSL=GLOB(0x238f668)<<< 250-AUTH LOGIN PLAIN
Password:
Net::SMTP::SSL=GLOB(0x238f668)>>> AUTH

1b74092373 tree-walk: micro-optimization in tree_entry_interesting
In the case of a wide breadth top-level tree (~2400 entries, all trees
in this case), we can see a noticeable cost in the profiler calling
strncmp() here. Most of the time we are at the base level of the
repository, so base is "" and baselen == 0, which means we will always
test true. Break out this one tiny case so we can short circuit the
strncmp() call.

Test cases are as follows. packages.git is the Arch Linux git-svn clone
of the packages repository which has the characteristics above.

Commands:
[1] packages.git, /usr/bin/time git log >/dev/null
[2] packages.git, /usr/bin/time git log -- autogen/trunk pacman/trunk wget/trunk >/dev/null
[3] linux.git, /usr/bin/time git log >/dev/null
[4] linux.git, /usr/bin/time git log -- drivers/ata drivers/uio tools >/dev/null

Results:
     before  after  %faster
[1]   2.56    2.55   0.4%
[2]  51.82   48.66   6.5%
[3]   5.58    5.61  -0.5%
[4]   1.55    1.51   0.2%

The takeaway here is this doesn't matter in many operations, but it does
for a certain style of repository and operation where it nets a 6.5%
measured improvement. The other changes are likely not significant by
reasonable statistics methods.

Note: the measured improvement when originally submitted was ~11% (43 to
38 secs) for operation [2]. At the time, the repository had 117220
commits; it now has 137537 commits.

The worktree_attributes variable (which is OPT_BOOLEAN) is initialized to

which is a bitfield of width 1. It is safe and even more correct to use

b04ba2bb42 parse-options: deprecate OPT_BOOLEAN
It is natural to expect that an option defined with OPT_BOOLEAN() could be
used in this way:

	int option = -1; /* unspecified */

	struct option options[] = {
		OPT_BOOLEAN(0, "option", &option, "set option"),
                OPT_END()
	};
	parse_options(ac, av, prefix, options, usage, 0);

        if (option < 0)
        	... do the default thing ...
	else if (!option)
		... --no-option was given ...
	else
		... --option was given ...

to easily tell three cases apart:

 - There is no mention of the `--option` on the command line;
 - The variable is positively set with `--option`; or
 - The variable is explicitly negated with `--no-option`.

Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable
every time `--option` is given, and resets it to zero when `--no-option`
is given.

As a first step to remedy this, introduce a true boolean OPT_BOOL(), and
rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN
and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and
OPTION_COUNTUP respectively.

This is what db7244b (parse-options new features., 2007-11-07) from four
years ago started by marking OPTION_BOOLEAN as "INCR would have been a
better name".

Some existing users do depend on the count-up semantics; for example,
users of OPT__VERBOSE() could use it to raise the verbosity level with
repeated use of `-v` on the command line, but they probably should be
rewritten to use OPT__VERBOSITY() instead these days.  I suspect that some
users of OPT__FORCE() may also use it to implement different level of
forcibleness but I didn't check.

On top of this patch, here are the remaining clean-up tasks that other
people can help:

 - Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the
   value that is set to the underlying variable, and if it can proven that
   the variable is only used as a boolean, replace it with OPT_BOOL(). If
   the caller does depend on the count-up semantics, replace it with
   OPT_COUNTUP() instead.

 - Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to
   set 1 to the variable for a true boolean, and otherwise replace it with
   OPTION_COUNTUP.

 - Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if
   they can be replaced with OPT__VERBOSITY().

I'll follow this message up with a separate patch as an example.

2b07ff3ffa gitweb: Fix links to lines in blobs when javascript-actions are enabled
The fixLinks() function adds 'js=1' to each link that does not already
have 'js' query parameter specified. This is used to signal to gitweb
that the browser can actually do javascript when these links are used.

There are two problems with the existing code:

  1. URIs with fragment and 'js' query parameter, like e.g.

        ...foo?js=0#l199

     were not recognized as having 'js' query parameter already.

  2. The 'js' query parameter, in the form of either '?js=1' or ';js=1'
     was appended at the end of URI, even if it included a fragment
     (had a hash part).  This lead to the incorrect links like this

        ...foo#l199?js=1

     instead of adding query parameter as last part of query, but
     before the fragment part, i.e.

        ...foo?js=1#l199

b4f223c636 Don't sort ref_list too early
get_ref_dir is called recursively for subdirectories, which means that
we were calling sort_ref_list for each directory of refs instead of
once for all the refs.  This is a massive wast of processing, so now
just call sort_ref_list on the result of the top-level get_ref_dir, so
that the sort is only done once.

In the common case of only a few different directories of refs the
difference isn't very noticable, but it becomes very noticeable when
you have a large number of direcotries containing refs (e.g. as
created by Gerrit).

f6f17885ba contrib/hooks: adapt comment about Debian install location for contrib hooks
Placing the contrib hooks into /usr/share/doc/ wasn't a good idea in the
first place.  According to the Debian policy they should be located in
/usr/share/git-core/, so let's put them there.

8557263953 apply --whitespace=error: correctly report new blank lines at end
Earlier, 77b15bb (apply --whitespace=warn/error: diagnose blank at EOF,
2009-09-03) cheated by reporting the line number of the hunk that contains
the offending line that adds new blank lines at the end of the file. All
other types of whitespace errors are reported with the line number in the
patch file that has the actual offending text.

c5aa90682f Revert removal of multi-match discard heuristic in 27af01
27af01d (xdiff/xprepare: improve O(n*m) performance in
xdl_cleanup_records(), 2011-08-17) was supposed to be a performance
boost only. However, it unexpectedly changed the behaviour of diff.

Revert a part of 27af01d that removes logic that mark lines as
"multi-match" (ie. dis[i] == 2). This was preventing the multi-match
discard heuristic (performed in xdl_cleanup_records() and
xdl_clean_mmatch()) from executing.

5e82123197 git-read-tree.txt: update sparse checkout examples
The negation example uses '*' to match everything. This used to work
before 9037026 (unpack-trees: fix sparse checkout's "unable to match
directories") because back then, the list of paths is used to match
sparse patterns, so with the patterns

    *
    !subdir/

subdir/ always matches any path that start with subdir/ and "*" has no
chance to get tested. The result is subdir is excluded.

After the said commit, a tree structure is dynamically created and
sparse pattern matching now follows closely how read_directory()
applies .gitignore. This solves one problem, but reveals another one.

With this new strategy, "!subdir/" rule will be only tested once when
"subdir" directory is examined. Entries inside subdir, when examined,
will match "*" and are (correctly) re-added again because any rules
without a slash will match at every directory level. In the end, "*"
can revert every negation rules.

In order to correctly exclude subdir, we must use

    /*
    !subdir

to limit "match all" rule at top level only.

"*" rule has no actual use in sparse checkout and can be confusing to
users. While we can automatically turn "*" to "/*", this violates
.gitignore definition. Instead, discourage "*" in favor of "/*" (in
the second example).

6d9990a959 mergetool: no longer need to save standard input
Earlier code wanted to run merge_file and prompt_after_failed_merge
both of which wanted to read from the standard input of the entire
script inside a while loop, which read from a pipe, and in order to
do so, it redirected the original standard input to another file
descriptor. We no longer need to do so after the previous change.

3e8e691abe mergetool: Use args as pathspec to unmerged files
Mergetool now treats its path arguments as a pathspec (like other git
subcommands), restricting action to the given files and directories.
Files matching the pathspec are filtered so mergetool only acts on
unmerged paths; previously it would assume each path argument was in an
unresolved state, and get confused when it couldn't check out their
other stages.

Running "git mergetool subdir" will prompt to resolve all conflicted
blobs under subdir.
