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>

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.

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.

With this installed in your $PATH, you can store
git-over-http passwords in your keychain by doing:
git config credential.helper osxkeychain
The code is based in large part on the work of Jay Soffian,
who wrote the helper originally for the initial, unpublished
version of the credential helper protocol.
This version will pass t0303 if you do:
GIT_TEST_CREDENTIAL_HELPER=osxkeychain \
GIT_TEST_CREDENTIAL_HELPER_SETUP="export HOME=$HOME" \
./t0303-credential-external.sh
The "HOME" setup is unfortunately necessary. The test
scripts set HOME to the trash directory, but this causes the

We already have tests for the internal helpers, but it's
nice to give authors of external tools an easy way to
sanity-check their helpers.
If you have written the "git-credential-foo" helper, you can
do so with:
GIT_TEST_CREDENTIAL_HELPER=foo \
make t0303-credential-external.sh
This assumes that your helper is capable of both storing and
retrieving credentials (some helpers may be read-only, and
they will fail these tests).
If your helper supports time-based expiration with a
configurable timeout, you can test that feature like this:
GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
make t0303-credential-external.sh

This is like "cache", except that we actually put the

course, but we do what we can to protect them by filesystem
permissions, and we warn the user in the documentation.
This is not unlike using .netrc to store entries, but it's a
little more user-friendly. Instead of putting credentials in
place ahead of time, we transparently store them after
prompting the user for them once.

When we need to prompt the user for input interactively, we
want to access their terminal directly. We can't rely on
stdio because it may be connected to pipes or files, rather
than the terminal. Instead, we use "getpass()", because it
abstracts the idea of prompting and reading from the
terminal. However, it has some problems:
1. It never echoes the typed characters, which makes it OK
for passwords but annoying for other input (like usernames).
2. Some implementations of getpass() have an extremely
small input buffer (e.g., Solaris 8 is reported to
support only 8 characters).
3. Some implementations of getpass() will fall back to
reading from stdin (e.g., glibc). We explicitly don't
want this, because our stdin may be connected to a pipe
speaking a particular protocol, and reading will
disrupt the protocol flow (e.g., the remote-curl
helper).
4. Some implementations of getpass() turn off signals, so
that hitting "^C" on the terminal does not break out of
the password prompt. This can be a mild annoyance.
Instead, let's provide an abstract "git_terminal_prompt"
function that addresses these concerns. This patch includes
an implementation based on /dev/tty, enabled by setting
HAVE_DEV_TTY. The fallback is to use getpass() as before.
