Let check_preimage() use memset() to initialize "struct checkout"
Every code site except check_preimage() uses either memset() or declares
a static instance of "struct checkout" to achieve proper initialization.
Lets use memset() instead of explicit initialization of all members here
too to be on the safe side in case this structure is expanded someday.

- use "[<repository> [<refspec>...]]" to indicate that <repository> and
<refspec> are optional, and that <refspec> cannot be specified
without specifying <repository>.
Note that when called without specifying <repository> (eg. "git fetch

remote-curl: ensure that URLs have a trailing slash
Previously, we blindly assumed that URLs passed to the remote-curl
helper did not end with a trailing slash.
Use the convenience function end_url_with_slash() from http.[ch] to
ensure that URLs have a trailing slash on invocation of the remote-curl
helper, and use the URL as one with a trailing slash throughout.
It is possible for users to pass a URL with a trailing slash to
remote-curl, by, say, setting it in remote.<name>.url in their git
config. The resulting requests have an empty path component (//) and may
break implementations of the http git protocol.

In 5f856dd (fix reflog entries for "git-branch"), it is mentioned that
'git branch -f' is intended to be equivalent to 'git reset'. Since we

log.decorate: only ignore it under "log --pretty=raw"
Unlike notes that are often multi-line and disrupting to be placed in many
output formats, a decoration is designed to be a small token that can be
tacked after an existing line of the output where a commit object name sits.
Disabling log.decorate for something like "log --oneline" would defeat the
purpose of the configuration.
We _might_ want to change it further in the future to force scripts that
do not want to be broken by random end user configurations to explicitly
say "log --no-decorate", but that would be an incompatible change that
needs the usual multi-release-cycle deprecation process.
Because log.decorate now shows decorations for --pretty=oneline,
we must explicitly turn it off when scripting. Otherwise,
users with log.decorate set will get cruft like:
$ git stash
Saved working directory and index state WIP on master: 2c1f7f5 (HEAD, master) commit subject
Instead of adding --no-decorate to the log command line,
let's just use the rev-list plumbing interface instead,
which does the right thing.
git-submodule has a similar call. Since it just counts the
commit lines, nothing is broken, but let's switch it, too,
for the sake of consistency and cleanliness.

ls-remote: fall-back to default remotes when no remote specified
Instead of breaking execution when no remote (as specified in the
variable dest) is specified when git-ls-remote is invoked, continue on
and let remote_get() handle it.
This way, we are able to use the default remotes (eg. "origin",
branch.<name>.remote), as git-fetch, git-push, and other users of
remote_get(), do.
If no suitable remote is found, exit with a message describing the
issue, instead of just the usage text, as we do previously.
Add several tests to check that git-ls-remote handles the
no-remote-specified situation.
Also add a test that "git ls-remote <pattern>" does not work; we are
unable to guess the remote in that situation, as are git-fetch and
git-push.
In that test, we are testing for messages coming from two separate
processes, but we should be OK, because the second message is triggered
by closing the fd which must happen after the first message is printed.

apply: Allow blank *trailing* context lines to match beyond EOF
In 51667147be, "git apply --whitespace=fix" was extended to
allow a blank context line to match beyond the end of the file,
but only if the context line was in the leading part of the
hunk (i.e. the hunk inserted additional contents at the end
of the file).
Drop the restriction that the context line must be in the
leading part of the hunk, thus allowing a file to be changed
from:
a

to:
b
a
(blank line)
Note that the blank line will be kept, because "--whitespace=fix"
only removes trailing blank lines that a hunk would add, never
trailing blank lines in the context.

The option tells the command to expire older reflog entries that refer to
commits that are no longer reachable from the tip of the ref the reflog is
associated with. To avoid repeated merge_base() invocations, we used to
mark commits that are known to be reachable by walking the history from
the tip until we hit commits that are older than expire-total (which is
the timestamp before which all the reflog entries are expired).
However, it is a different matter if a commit is _not_ known to be
reachable and the commit is known to be unreachable. Because you can
rewind a ref to an ancient commit and then reset it back to the original
tip, a recent reflog entry can point at a commit that older than the
expire-total timestamp and we shouldn't expire it. For that reason, we
had to run merge-base computation when a commit is _not_ known to be
reachable.
This introduces a lazy/on-demand traversal of the history to mark
reachable commits in steps. As before, we mark commits that are newer
than expire-total to optimize the normal case before walking reflog, but
we dig deeper from the commits the initial step left off when we encounter
a commit that is not known to be reachable.
In many places in test suite we have "sleep"s that do not have to be
there.
- I do not simply see the point of the one in t3500. It may be making
sure that the timestamp order of commits generated during the test is
stable, in which case test_tick is the right ingredient to use without
wasting tester's time.
- The one in t4011 is to make sure that the plumbing diff-index notices
the stat-dirtyness of a removed then identically recreated symlink.
Keeping the old symlink around to make sure that a newly created
symlink gets different ino would be sufficient for that purpose.
- The one in t7600 is to make sure that "git merge" does not get confused
by stat-dirty "file" in the working tree. Again, keeping the old file
around and creating an identical copy to ensure a different ino would
be sufficient for that purpose.
The "racy git" tests in t0010 are inherently about mtime between the index
itself and index entries. The "sleep" in that test must stay as they are.

Many scripts, most notably gitk, rely on output from the log family of
command not to be molested by random user configuration. This is
especially true when --pretty=raw is given.
Just like we disable notes output unless the command line explicitly
asks for --show-notes, disable the decoration code unless --decorate is
given explicitly from the command line and --pretty or --oneline is
given.
Could it be that you are using a third party iconv library?
I've experienced this on another system and the problem was related
to curl. In that case, curl was linked against an external iconv and
not the native library, so if I tried to build with curl support, I had
to also build against the external iconv library.

or later hides symbols from programs, which leads to implicit declaration
of functions, making the return value to be assumed an int. On architectures

that all JavaScript minifiers will also minify CSS files.
This patch also adds the GITWEB_PROGRAMS variable to the Makefile

OTHER_PROGRAMS when we need to know just the gitweb dependencies.
Though the bandwidth savings will not be as dramatic as with

builtin_diff calls fill_mmfile fairly early, which in turn
calls diff_populate_filespec, which actually retrieves the
file's blob contents into a buffer. Long ago, this was
sensible as we would need to look at the blobs eventually.
These days, however, we may not ever want those blobs if we
end up using a textconv cache, and for large binary files
(exactly the sort for which you might have a textconv
cache), just retrieving the objects can be costly.
This patch just pushes the fill_mmfile call a bit later, so
we can avoid populating the filespec in some cases. There
is one thing to note that looks like a bug but isn't. We
push the fill_mmfile down into the first branch of a
conditional. It seems like we would need it on the other
branch, too, but we don't; fill_textconv does it for us (in
fact, before this, we were just writing over the results of
the fill_mmfile on that branch).
Here's a timing sample on a commit with 45 changed jpgs and
avis. The result is fully textconv cached, but we still
wasted a lot of time just pulling the blobs from storage.
The total size of the blobs (source and dest) is about
180M.
[before]
$ time git show >/dev/null
real 0m0.352s
user 0m0.148s
sys 0m0.200s
[after]
$ time git show >/dev/null
real 0m0.009s
user 0m0.004s
sys 0m0.004s
And that's on a warm cache. On a cold cache, the "after"
case is not much worse, but the "before" case has to do an
extra 180M of I/O.

Running a textconv filter can take a long time. It's
particularly bad for a large file which needs to be spooled
to disk, but even for small files, the fork+exec overhead
can add up for something like "git log -p".
This patch uses the notes-cache mechanism to keep a fast
cache of textconv output. Caches are stored in
refs/notes/textconv/$x, where $x is the userdiff driver
defined in gitattributes.
Caching is enabled only if diff.$x.cachetextconv is true.
In my test repo, on a commit with 45 jpg and avi files
changed and a textconv to show their exif tags:
[before]
$ time git show >/dev/null
real 0m13.724s
user 0m12.057s
sys 0m1.624s
[after, first run]
$ git config diff.mfo.cachetextconv true
$ time git show >/dev/null
real 0m14.252s
user 0m12.197s
sys 0m1.800s
[after, subsequent runs]
$ time git show >/dev/null
real 0m0.352s
user 0m0.148s
sys 0m0.200s
So for a slight (3.8%) cost on the first run, we achieve an
almost 40x speed up on subsequent runs.

Notes provide a fast lookup mechanism for data keyed by
sha1. This is ideal for caching certain operations, like
textconv filters.
This patch builds some infrastructure to make it simpler to
use notes trees as caches. In particular, caches:
1. don't have arbitrary commit messages. They store a
cache validity string in the commit, and clear the tree
when the cache validity string changes.
2. don't keep any commit history. The accumulated history
of a a cache is just useless cruft.
3. use a looser form of locking for ref updates. If two
processes try to write to the cache simultaneously, it
is OK if one overwrites the other, losing some changes.
It's just a cache, so we will just end up with an extra
miss.

Until now, this has been part of the commit-tree builtin.
However, it is already used by other builtins (like commit,
merge, and notes), and it would be useful to access it from
library code.
The check_valid helper has to come along, too, but is given
a more library-ish name of "assert_sha1_type".
Otherwise, the code is unchanged. There are still a few
rough edges for a library function, like printing the utf8
warning to stderr, but we can address those if and when they
come up as inappropriate.

When an HTTP request returns a 401, Git will currently fail with a
confusing message saying that it got a 401, which is not very
descriptive.
Currently if a user wants to use Git over HTTP, they have to use one
URL with the username in the URL (e.g. "http://user@host.com/repo.git")
for write access and another without the username for unauthenticated
read access (unless they want to be prompted for the password each
time). However, since the HTTP servers will return a 401 if an action
requires authentication, we can prompt for username and password if we
see this, allowing us to use a single URL for both purposes.
This patch changes http_request to prompt for the username and password,
then return HTTP_REAUTH so http_get_strbuf can try again. If it gets
a 401 even when a user/pass is supplied, http_request will now return
HTTP_NOAUTH which remote_curl can then use to display a more
intelligent error message that is less confusing.
