gitweb: Fix 'grep' search for multiple matches in file
Commit
ff7f218 (gitweb: Fix file links in "grep" search, 2012-01-05),
added $file_href variable, to reduce duplication and have the fix
applied in single place.
Unfortunately it made variable defined inside the loop, not taking into
account the fact that $file_href was set only if file changed.
Therefore for files with multiple matches $file_href was undefined for
second and subsequent matches.
Fix this bug by moving $file_href declaration outside loop.
Adds tests for almost all forms of sarch in gitweb, which were missing
from testuite. Note that it only tests if there are no warnings, and
it doesn't check that gitweb finds what it should find.

Makefile: Change the default compiler from "gcc" to "cc"
Ever since the very first commit to git.git we've been setting CC to
"gcc". Presumably this is behavior that Linus copied from the Linux
Makefile.
However unlike Linux Git is written in ANSI C and supports a multitude
of compilers, including Clang, Sun Studio, xlc etc. On my Linux box
"cc" is a symlink to clang, and on a Solaris box I have access to "cc"
is Sun Studio's CC.
Both of these are perfectly capable of compiling Git, and it's
annoying to have to specify CC=cc on the command-line when compiling
Git when that's the default behavior of most other portable programs.
So change the default to "cc". Users who want to compile with GCC can
still add "CC=gcc" to the make(1) command-line, but those users who
don't have GCC as their "cc" will see expected behavior, and as a
bonus we'll be more likely to smoke out new compilation warnings from
our distributors since they'll me using a more varied set of compilers
by default.

commit: ignore intent-to-add entries instead of refusing
Originally, "git add -N" was introduced to help users from forgetting to
add new files to the index before they ran "git commit -a". As an attempt
to help them further so that they do not forget to say "-a", "git commit"
to commit the index as-is was taught to error out, reminding the user that
they may have forgotten to add the final contents of the paths before
running the command.
This turned out to be a false "safety" that is useless. If the user made
changes to already tracked paths and paths added with "git add -N", and
then ran "git add" to register the final contents of the paths added with
"git add -N", "git commit" will happily create a commit out of the index,
without including the local changes made to the already tracked paths. It
was not a useful "safety" measure to prevent "forgetful" mistakes from
happening.
It turns out that this behaviour is not just a useless false "safety", but
actively hurts use cases of "git add -N" that were discovered later and
have become popular, namely, to tell Git to be aware of these paths added
by "git add -N", so that commands like "git status" and "git diff" would
include them in their output, even though the user is not interested in
including them in the next commit they are going to make.
Fix this ancient UI mistake, and instead make a commit from the index
ignoring the paths added by "git add -N" without adding real contents.

As such dirtiness expressed by the suffix does not affect the result of

With problematic versions of zsh, after running
emulate sh
fn () {
var='one two'
for v in $var; do echo $v; done
}
x=$(fn)

printing "$x" results in two lines as expected, but printing "$y" results
in a single line because $var is expanded as a single word when evaluating
fn to compute y.
So avoid the construct, and use an explicit 'test -n "$foo" || foo=$(bar)'
instead.

mailmap: always return a plain mail address from map_user()
The callers of map_user() give email and name to it, and expect to get the
up-to-date email and/or name to be used in their output. The function
rewrites the given buffers in place. To optimize the majority of cases,
the function returns 0 when it did not do anything, and it returns 1 when
the caller should use the updated contents.
The 'email' input to the function is terminated by '>' or a NUL (whichever
comes first) for historical reasons, but when a rewrite happens, the value
is replaced with the mailbox inside the <> pair. However, it failed to
meet this expectation when it only rewrote the name part without rewriting
the email part, and the email in the input was terminated by '>'.
This causes an extra '>' to appear in the output of "blame -e", because the
caller does send in '>'-terminated email, and when the function returned 1
to tell it that rewriting happened, it appends '>' that is necessary when
the email part was rewritten.
The patch looks bigger than it actually is, because this change makes a
variable that points at the end of the email part in the input 'p' live
much longer than it used to, deserving a more descriptive name.

Fix build problems related to profile-directed optimization
There was a number of problems I ran into when trying the
profile-directed optimizations added by Andi Kleen in git commit
7ddc2710b9. (This was using gcc 4.4 found on many enterprise
distros.)
1) The -fprofile-generate and -fprofile-use commands are incompatible
with ccache; the code ends up looking in the wrong place for the gcda
files based on the ccache object names.
2) If the makefile notices that CFLAGS are different, it will rebuild
all of the binaries. Hence the recipe originally specified by the
INSTALL file ("make profile-all" followed by "make install") doesn't
work. It will appear to work, but the binaries will end up getting
built with no optimization.
This patch fixes this by using an explicit set of options passed via
the PROFILE variable then using this to directly manipulate CFLAGS and
EXTLIBS.
The developer can run "make PROFILE=BUILD all ; sudo make
PROFILE=BUILD install" automatically run a two-pass build with the
test suite run in between as the sample workload for the purpose of
recording profiling information to do the profile-directed
optimization.
Alternatively, the profiling version of binaries can be built using:
make PROFILE=GEN PROFILE_DIR=/var/cache/profile all
make PROFILE=GEN install
and then after git has been used for a while, the optimized version of
the binary can be built as follows:
make PROFILE=USE PROFILE_DIR=/var/cache/profile all
make PROFILE=USE install

fast forwarding.

$ git merge --ff-only v1.7.9^0

The same codepath is used to read back the timestamp that we have
already recorded in the headers of commit and tag objects; because
of this, such a commit with timestamp "0 +0000" cannot be rebased or
amended very easily.
Teach parse_date() codepath to special case a string of the form
"<digits> +<4-digits>" to work this issue around, but require that
there is no other cruft around the string when parsing a timestamp
of this format for safety.

gitweb: Allow UTF-8 encoded CGI query parameters and path_info
Gitweb forgot to turn query parameters into UTF-8. This results in a bug
that one cannot search for a string with characters outside US-ASCII. For
example searching for "Michał Kiedrowicz" (containing letter 'ł' - LATIN
SMALL LETTER L WITH STROKE, with Unicode codepoint U+0142, represented
with 0xc5 0x82 bytes in UTF-8 and percent-encoded as %C5%82) result in the
following incorrect data in search field
MichaÅ\202 Kiedrowicz
This is caused by CGI by default treating '0xc5 0x82' bytes as two
characters in Perl legacy encoding latin-1 (iso-8859-1), because 's'
query parameter is not processed explicitly as UTF-8 encoded string.
The solution used here follows "Using Unicode in a Perl CGI script"
article on http://www.lemoda.net/cgi/perl-unicode/index.html:
use CGI;
use Encode 'decode_utf8;
my $value = params('input');
$value = decode_utf8($value);
Decoding UTF-8 is done when filling %input_params hash and $path_info
variable; the former requires to move from explicit $cgi->param(<label>)
to $input_params{<name>} in a few places, which is a good idea anyway.
Also add -override=>1 parameter to $cgi->textfield() invocation in search
form. Otherwise CGI would use values from query string if it is present,
filling value from $cgi->param... without decode_utf8(). As we are using
value of appropriate parameter anyway, -override=>1 doesn't change the
situation but makes gitweb fill search field correctly.
We could simply use the '-utf8' pragma (via "use CGI '-utf8';") to solve
this, but according to CGI.pm documentation, it may cause problems with
POST requests containing binary files, and it requires CGI 3.31 (I think),

grep: pre-load userdiff drivers when threaded
The low-level grep_source code will automatically load the
userdiff driver to see whether a file is binary. However,
when we are threaded, it will load the drivers in a
non-deterministic order, handling each one as its assigned
thread happens to be scheduled.
Meanwhile, the attribute lookup code (which underlies the
userdiff driver lookup) is optimized to handle paths in
sequential order (because they tend to share the same
gitattributes files). Multi-threading the lookups destroys
the locality and makes this optimization less effective.
We can fix this by pre-loading the userdiff driver in the
main thread, before we hand off the file to a worker thread.
My best-of-five for "git grep foo" on the linux-2.6
repository went from:
real 0m0.391s
user 0m1.708s
sys 0m0.584s
to:
real 0m0.360s
user 0m1.576s

This patch teaches git-grep to use the same attribute lookup
that is used by git-diff. We could add a new "grep" flag,

Despite the name, the "-diff" attribute (or "diff=foo" and

2. Ones which really just wanted to grep a buffer (i.e.,
git log --grep).
Callers in set (1) should now be using grep_source. Callers
in set (2) always pass NULL for the "name" parameter of
grep_buffer. We can therefore get rid of this now-useless
parameter.

convert git-grep to use grep_source interface
The grep_source interface (as opposed to grep_buffer) will
eventually gives us a richer interface for telling the
low-level grep code about our buffers. Eventually this will
lead to things like better binary-file handling. For now, it
lets us drop a lot of now-redundant code.
The conversion is mostly straight-forward. One thing to note
is that the memory ownership rules for "struct grep_source"
are different than the "struct work_item" found here (the
former will copy things like the filename, rather than
taking ownership). Therefore you will also see some slight
tweaking of when filename buffers are released.

grep: refactor the concept of "grep source" into an object
The main interface to the low-level grep code is
grep_buffer, which takes a pointer to a buffer and a size.
This is convenient and flexible (we use it to grep commit
bodies, files on disk, and blobs by sha1), but it makes it
hard to pass extra information about what we are grepping
(either for correctness, like overriding binary
auto-detection, or for optimizations, like lazily loading
blob contents).
Instead, let's encapsulate the idea of a "grep source",
including the buffer, its size, and where the data is coming
from. This is similar to the diff_filespec structure used by
the diff code (unsurprising, since future patches will
implement some of the same optimizations found there).
The diffstat is slightly scarier than the actual patch
content. Most of the modified lines are simply replacing
access to raw variables with their counterparts that are now
in a "struct grep_source". Most of the added lines were
taken from builtin/grep.c, which partially abstracted the
idea of grep sources (for file vs sha1 sources).
Instead of dropping the now-redundant code, this patch
leaves builtin/grep.c using the traditional grep_buffer
interface (which now wraps the grep_source interface). That
makes it easy to test that there is no change of behavior
(yet).

grep: move sha1-reading mutex into low-level code
The multi-threaded git-grep code needs to serialize access
to the thread-unsafe read_sha1_file call. It does this with
a mutex that is local to builtin/grep.c.
Let's instead push this down into grep.c, where it can be
used by both builtin/grep.c and grep.c. This will let us
safely teach the low-level grep.c code tricks that involve
reading from the object db.

grep: make locking flag global
The low-level grep code traditionally didn't care about
threading, as it doesn't do any threading itself and didn't
call out to other non-thread-safe code. That changed with
0579f91 (grep: enable threading with -p and -W using lazy
attribute lookup, 2011-12-12), which pushed the lookup of
funcname attributes (which is not thread-safe) into the
low-level grep code.
As a result, the low-level code learned about a new global
"grep_attr_mutex" to serialize access to the attribute code.
A multi-threaded caller (e.g., builtin/grep.c) is expected
to initialize the mutex and set "use_threads" in the
grep_opt structure. The low-level code only uses the lock if
use_threads is set.
However, putting the use_threads flag into the grep_opt
struct is not the most logical place. Whether threading is
in use is not something that matters for each call to
grep_buffer, but is instead global to the whole program
(i.e., if any thread is doing multi-threaded grep, every
other thread, even if it thinks it is doing its own
single-threaded grep, would need to use the locking). In
practice, this distinction isn't a problem for us, because
the only user of multi-threaded grep is "git-grep", which
does nothing except call grep.
This patch turns the opt->use_threads flag into a global
flag. More important than the nit-picking semantic argument
above is that this means that the locking functions don't
need to actually have access to a grep_opt to know whether
to lock. Which in turn can make adding new locks simpler, as
we don't need to pass around a grep_opt.

find_pack_entry(): do not keep packed_git pointer locally
Commit
f7c22cc (always start looking up objects in the last used pack
first - 2007-05-30) introduce a static packed_git* pointer as an
optimization. The kept pointer however may become invalid if
free_pack_by_name() happens to free that particular pack.
Current code base does not access packs after calling
free_pack_by_name() so it should not be a problem. Anyway, move the
pointer out so that free_pack_by_name() can reset it to avoid running
into troubles in future.

request-pull: explicitly ask tags/$name to be pulled
When asking for a tag to be pulled, disambiguate by leaving tags/ prefix
in front of the name of the tag. E.g.
... in the git repository at:
git://example.com/git/git.git/ tags/v1.2.3
for you to fetch changes up to 123456...
This way, older versions of "git pull" can be used to respond to such a
request more easily, as "git pull $URL v1.2.3" did not DWIM to fetch
v1.2.3 tag in older versions. Also this makes it clearer for humans that
the pull request is made for a tag and he should anticipate a signed one.
