This brings back some of the performance lost in optimizing recency
order inside pack objects. We were doing extreme amounts of object
re-traversal: for the 2.14 million objects in the Linux kernel
repository, we were calling add_to_write_order() over 1.03 billion times
(a 0.2% hit rate, making 99.8% of of these calls extraneous).
Two optimizations take place here- we can start our objects array
iteration from a known point where we left off before we started trying
to find our tags, and we don't need to do the deep dives required by
add_family_to_write_order() if the object has already been marked as
filled.
These two optimizations bring some pretty spectacular results via `perf
stat`:
task-clock: 83373 ms --> 43800 ms (50% faster)
cycles: 221,633,461,676 --> 116,307,209,986 (47% fewer)
instructions: 149,299,179,939 --> 122,998,800,184 (18% fewer)

strbuf.c: remove unnecessary strbuf_grow() from strbuf_getwholeline()
This use of strbuf_grow() is a historical artifact that was once used to
ensure that strbuf.buf was allocated and properly nul-terminated. This
was added before the introduction of the slopbuf in b315c5c0, which
guarantees that strbuf.buf always points to a usable nul-terminated string.
So let's remove it.

You can't currently run git-pull or git-rebase from outside
of the work tree, even with GIT_WORK_TREE set, due to an
overeager require_work_tree function. Commit e2eb527
documents this problem and provides the infrastructure for a
fix, but left it to later commits to audit and update
individual scripts.
Changing these scripts to use require_work_tree_exists is
easy to verify. We immediately call cd_to_toplevel, anyway.
Therefore no matter which function we use, the state
afterwards is one of:
1. We have a work tree, and we are at the top level.
2. We don't have a work tree, and we have died.
The only catch is that we must also make sure no code that
ran before the cd_to_toplevel assumed that we were already
in the working tree.
In this case, we will only have included shell libraries and
called set_reflog_action, neither of which care about the
current working directory at all.

The commit message for c976d41 (git-branch: add options and tests for

documented anywhere, and it does not appear in any of the tests.
Worse yet, the name of the actual file is "RENAMED-REF".
This was supposed to hold the commit object name at the tip of the branch
the most recent "branch -m/-M" renamed, but that is not necessary in order
to be able to recover from a mistake. Even when "branch -M A B" overwrites
an existing branch B, what is kept in RENAMED-REF is the commit at the tip

attr.c: respect core.ignorecase when matching attribute patterns
When core.ignorecase is true, the file globs configured in the
.gitattributes file should be matched case-insensitively against the paths
in the working directory. Let's do so.
Plus, add some tests.
The last set of tests is performed only on a case-insensitive filesystem.
Those tests make sure that git handles the case where the .gitignore file
resides in a subdirectory and the user supplies a path that does not match
the case in the filesystem. In that case^H^H^H^Hsituation, part of the
path supplied by the user is effectively interpreted case-insensitively,
and part of it is dependent on the setting of core.ignorecase. git will
currently only match the portion of the path below the directory holding
the .gitignore file according to the setting of core.ignorecase.
This is also partly future-proofing. Currently, git builds the attr stack
based on the path supplied by the user, so we don't have to do anything
special (like use strcmp_icase) to handle the parts of that path that don't
match the filesystem with respect to case. If git instead built the attr
stack by scanning the repository, then the paths in the origin field would
not necessarily match the paths supplied by the user. If someone makes a
change like that in the future, these tests will notice.

attr: read core.attributesfile from git_default_core_config
This code calls git_config from a helper function to parse the config entry
it is interested in. Calling git_config in this way may cause a problem if
the helper function can be called after a previous call to git_config by
another function since the second call to git_config may reset some
variable to the value in the config file which was previously overridden.
The above is not a problem in this case since the function passed to
git_config only parses one config entry and the variable it sets is not
assigned outside of the parsing function. But a programmer who desires
all of the standard config options to be parsed may be tempted to modify
git_attr_config() so that it falls back to git_default_config() and then it
_would_ be vulnerable to the above described behavior.
So, move the call to git_config up into the top-level cmd_* function and
move the responsibility for parsing core.attributesfile into the main
config file parser.
Which is only the logical thing to do ;-)

attr.c: avoid inappropriate access to strbuf "buf" member
This code sequence performs a strcpy into the buf member of a strbuf
struct. The strcpy may move the position of the terminating nul of the
string and effectively change the length of string so that it does not
match the len member of the strbuf struct.
Currently, this sequence works since the strbuf was given a hint when it
was initialized to allocate enough space to accomodate the string that will
be strcpy'ed, but this is an implementation detail of strbufs, not a
guarantee.
So, lets rework this sequence so that the strbuf is only manipulated by
strbuf functions, and direct modification of its "buf" member is not
necessary.

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.

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.

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

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).

merge-recursive: Do not look at working tree during a virtual ancestor merge
Fix another instance of a recursive merge incorrectly paying attention to
the working tree file during a virtual ancestor merge, that resulted in
spurious and useless "addinfo_cache failed" error message.
When running git describe --dirty the index should be refreshed. Previously
the cached index would cause describe to think that the index was dirty when,

The issue was exposed by python setuptools which hardlinks files into another
directory when building a distribution.
"git diff -p" piped to external diffstat and "git diff --stat" may see
different patch text (both are valid and describe the same change
correctly) when counting the number of added and deleted lines, arriving
at different results to confuse the users, as --stat/--numstat codepath
always uses the hardcoded -U0 as the context length.
Make --stat/--numstat codepath to honor the context length the same way
as the textual patch codepath does to avoid this problem.
get_one_patchid() uses a rather dumb heuristic to determine if the
passed buffer is part of the next commit. Whenever the first 40 bytes

next_sha1.
Once the current line is longer than the fixed buffer, this will break
(provided the additional bytes make a valid hexadecimal sha1). As a result
patch-id returns incorrect results. Instead, use strbuf and read one line
at a time.

git-read-tree.txt: correct sparse-checkout and skip-worktree description
The description of .git/info/sparse-checkout and
skip-worktree is exactly the opposite of what is true, which is:
If a file matches a pattern in sparse-checkout, then (it is to be
checked out and therefore) skip-worktree is unset for that file;
otherwise, it is set (so that it is not checked out).
Currently, the opposite is documented, and (consistently) read-tree's
behavior with respect to bit flips is descibed incorrectly.
Fix it.
In hindsight, it would have been much better to have a "sparse-ignore"

and the file logic would be analogous to that of .gitignore, excludes
and skip-worktree.

when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.

well-formed XML. Unescaped control characters cannot appear within a
contents of a valid XML document.
This will cause the browser to display one of the following warnings:
* Safari v5.1 (6534.50) & Google Chrome v13.0.782.112:
This page contains the following errors:
error on line 657 at column 38: PCDATA invalid Char value 12
Below is a rendering of the page up to the first error.
* Mozilla Firefox 3.6.19 & Mozilla Firefox 5.0:
XML Parsing Error: not well-formed
Location:
http://path/to/git/repo/blah/blah
Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7
using arch/ia64/kernel/unwind.c from the Linux kernel.
When syntax highlighter is not used, control characters are replaced
by esc_html(), but with syntax highlighter they were passed through to
browser (to_utf8() doesn't remove control characters).
Introduce sanitize() subroutine which strips forbidden characters, but
does not perform HTML escaping, and use it in git_blob() to sanitize
syntax highlighter output for XHTML.
Note that excluding "\t" (U+0009), "\n" (U+000A) and "\r" (U+000D) is
not strictly necessary, atleast for currently the only callsite: "\t"
tabs are replaced by spaces by untabify(), "\n" is stripped from each
line before processing it, and replacing "\r" could be considered
improvement.

Documentation/gitnamespaces.txt: cater to older asciidoc
Older asciidoc (e.g. 8.2.5 on Centos 5.5) is unhappy if a manpage does not
have a SYNOPSIS section. Show a sample (and a possibly bogus) command line
of running two commands that pay attention to this environment variable
with a customized value.

Filter-branch already requires that we have a clean work
tree before starting. However, it failed to refresh the
index before checking, which means it could be wrong in the
case of stat-dirtiness.
Instead of simply adding a call to refresh the index, let's
switch to using the require_clean_work_tree function
provided by git-sh-setup. It does exactly what we want, and
with fewer lines of code and more specific output messages.

t6019: avoid refname collision on case-insensitive systems
The criss-cross tests kept failing for me because of collisions of 'a'
with 'A' etc. Prefix the lowercase refnames with an extra letter to
disambiguate.

This is similar to sq_dequote_to_argv, but more convenient
if you have an argv_array. It's tempting to just feed the
components of the argv_array to sq_dequote_to_argv instead,
but:
1. It wouldn't maintain the NULL-termination invariant
of argv_array.
2. It doesn't match the memory ownership policy of
argv_array (in which each component is free-able, not a
pointer into a separate buffer).

The submodule code recently grew generic code to build a
dynamic argv array. Many other parts of the code can reuse
this, too, so let's make it generically available.
There are two enhancements not found in the original code:
1. We now handle the NULL-termination invariant properly,
even when no strings have been pushed (before, you
could have an empty, NULL argv). This was not a problem
for the submodule code, which always pushed at least
one argument, but was not sufficiently safe for
generic code.
2. There is a formatted variant of the "push" function.
This is a convenience function which was not needed by
the submodule code, but will make it easier to port
other users to the new code.

Commit 758e915 made sq_quote_next static, removing it from
quote.h. However, it forgot to update the related comment,
making it appear as a confusing description of sq_quote_to_argv.
Let's remove the crufty bits, and elaborate more on sq_quote_to_argv.
