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.

request-pull: do not emit "tag" before the tagname
The whole point of the recent update to allow "git pull $url $tagname" is
so that the integrator does not have to store the (signed) tag that is
used to convey authenticity to be recorded in the resulting merge in the
local repository's tag namespace. Asking for a merge be made with "git
pull $url tag $tagname" defeats it.
Note that the request can become ambiguous if the requestor has a branch
with the same name as the tag, but that is not a new problem limited to
pulling. I wouldn't mind if somebody wants to add disambiguation to the
find_matching_ref logic in the script as a separate patch, though.
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.

lf_to_crlf_filter(): tell the caller we added "\n" when draining
This can only happen when the input size is multiple of the

it added the "\n" it could not add during the last round.
request-pull: update the "pull" command generation logic
The old code that insisted on asking for the tip of a branch to be pulled
were not updated when we started allowing for a tag to be pulled. When a
tag points at an older part of the history and there is no branch that
points at the tagged commit, the script failed to say which ref is to be
pulled.
commit_tree(): refuse commit messages that contain NULs
Current implementation sees NUL as terminator. If users give a message
with NUL byte in it (e.g. editor set to save as UTF-16), the new commit
message will have NULs. However following operations (displaying or
amending a commit for example) will not keep anything after the first NUL.
Stop user right when they do this. If NUL is added by mistake, they have
their chance to fix. Otherwise, log messages will no longer be text "git
log" and friends would grok.

There wan't a way for commit_tree() to notice if the message the caller
prepared contained a NUL byte, as it did not take the length of the
message as a parameter. Use a pointer to a strbuf instead, so that we can
either choose to allow low-level plumbing commands to make commits that
contain NUL byte in its message, or forbid NUL everywhere by adding the
check in commit_tree(), in later patches.

We want to run tests in a predictable, sterile environment
so we can get repeatable results. They should take as
little input as possible from the environment outside the
test script. We already sanitize environment variables, but
leave stdin untouched. This means that scripts can
accidentally be impacted by content on stdin, or whether
stdin isatty().
Furthermore, scripts reading from stdin can be annoying to
outer loops which care about their stdin offset, like:
while read sha1; do
make test
done
A test which accidentally reads stdin would soak up all of
the rest of the input intended for the outer shell loop.
Let's redirect stdin from /dev/null, which solves both
of these problems. It won't detect tests accidentally
reading from stdin, but since doing so now gives a
deterministic result, we don't need to consider that an
error.
We'll also leave file descriptor 6 as a link to the original
stdin. Tests shouldn't need to look at this, but it can be
convenient for inserting interactive commands while
debugging tests (e.g., you could insert "bash <&6 >&3 2>&4"
to run interactive commands in the environment of the test
script).

checkout_merged(): squelch false warning from some gcc

Squelch it with an unnecessary initialization; it is not like a single
assignment matters to the performance in this codepath that writes out
to the filesystem with checkout_entry() anyway.

This script uses the following idiom to start each test in a known
good state:
test_expect_success 'some commands use a pager' '
rm -f paginated.out || cleanup_fail &&
test_terminal git log &&
test -e paginated.out
'
where "cleanup_fail" is a function that prints an error message and
errors out.
That is bogus on three levels:
- Cleanup commands like "rm -f" and "test_unconfig" are designed not
to fail, so this logic would never trip.
- If they were to malfunction anyway, it is not useful to set apart
cleanup commands as a special kind of failure with a special error
message. Whichever command fails, the next step is to investigate
which command that was, for example by running tests with
"prove -e 'sh -x'", and fix it.
- Relying on left-associativity of mixed &&/|| lists makes the code
somewhat cryptic.
The fix is simple: drop the "|| cleanup_fail" in each test and the
definition of the "cleanup_fail" function so no new callers can arise.

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.

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.

This function was used for comparing local and remote ref
names during fetch (which makes it a candidate for "most
confusingly named function of the year").
It no longer has any callers, so let's get rid of it.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
When we are determining the list of refs to fetch via
fetch-pack, we have two sets of refs to compare: those on
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.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.

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.
