The paragraph to encourage use of "--" in scripts belongs to the
bullet point that describes the behaviour for a command line without
the explicit "--" disambiguation; it is not a supporting explanation
for the entire bulletted list, and it is wrong to make it a separate

When fed such a commit, --format='%ci' fails to parse it, and gives

Originally the "--quiet" option was parsed by the
diff-option parser into the internal QUICK option. This had
the effect of silencing diff output from the log (which was
not intended, but happened to work and people started to
use it). But it also had other odd side effects at the diff
level (for example, it would suppress the second commit in
"git show A B").
To fix this, commit 1c40c36 converted log to parse-options
and handled the "quiet" option separately, not passing it
on to the diff code. However, it simply ignored the option,
which was a regression for people using it as a synonym for
"-s". Commit 01771a8 then fixed that by interpreting the
option to add DIFF_FORMAT_NO_OUTPUT to the list of output
formats.
However, that commit did not fix it in all cases. It sets
the flag after setup_revisions is called. Naively, this
makes sense because you would expect the setup_revisions
parser to overwrite our output format flag if "-p" or
another output format flag is seen.
However, that is not how the NO_OUTPUT flag works. We
actually store it in the bit-field as just another format.
At the end of setup_revisions, we call diff_setup_done,
which post-processes the bitfield and clears any other
formats if we have set NO_OUTPUT. By setting the flag after
setup_revisions is done, diff_setup_done does not have a
chance to make this tweak, and we end up with other format
options still set.
As a result, the flag would have no effect in "git log -p
--quiet" or "git show --quiet". Fix it by setting the
format flag before the call to setup_revisions.

All of the smart-http GET requests go through the http_get_*
functions, which will prompt for credentials and retry if we
see an HTTP 401.
POST requests, however, do not go through any central point.
Moreover, it is difficult to retry in the general case; we
cannot assume the request body fits in memory or is even
seekable, and we don't know how much of it was consumed
during the attempt.
Most of the time, this is not a big deal; for both fetching
and pushing, we make a GET request before doing any POSTs,
so typically we figure out the credentials during the first
request, then reuse them during the POST. However, some
servers may allow a client to get the list of refs from
receive-pack without authentication, and then require
authentication when the client actually tries to POST the
pack.
This is not ideal, as the client may do a non-trivial amount
of work to generate the pack (e.g., delta-compressing
objects). However, for a long time it has been the
recommended example configuration in git-http-backend(1) for
setting up a repository with anonymous fetch and
authenticated push. This setup has always been broken
without putting a username into the URL. Prior to commit
986bbc0, it did work with a username in the URL, because git
would prompt for credentials before making any requests at
all. However, post-986bbc0, it is totally broken. Since it
has been advertised in the manpage for some time, we should
make sure it works.
Unfortunately, it is not as easy as simply calling post_rpc
again when it fails, due to the input issue mentioned above.
However, we can still make this specific case work by
retrying in two specific instances:
1. If the request is large (bigger than LARGE_PACKET_MAX),
we will first send a probe request with a single flush
packet. Since this request is static, we can freely
retry it.
2. If the request is small and we are not using gzip, then
we have the whole thing in-core, and we can freely
retry.
That means we will not retry in some instances, including:
1. If we are using gzip. However, we only do so when
calling git-upload-pack, so it does not apply to
pushes.
2. If we have a large request, the probe succeeds, but
then the real POST wants authentication. This is an
extremely unlikely configuration and not worth worrying
about.
While it might be nice to cover those instances, doing so
would be significantly more complex for very little
real-world gain. In the long run, we will be much better off
when curl learns to internally handle authentication as a
callback, and we can cleanly handle all cases that way.

Most of our http requests go through the http_request()
interface, which does some nice post-processing on the
results. In particular, it handles prompting for missing
credentials as well as approving and rejecting valid or
invalid credentials. Unfortunately, it only handles GET
requests. Making it handle POSTs would be quite complex, so
let's pull result handling code into its own function so
that it can be reused from the POST code paths.

Some sites set up http access to repositories such that
fetching is anonymous and unauthenticated, but pushing is
authenticated. While there are multiple ways to do this, the
technique advertised in the git-http-backend manpage is to
block access to locations matching "/git-receive-pack$".
Let's emulate that advice in our test setup, which makes it
clear that this advice does not actually work.

We do not currently test authentication for smart-http repos
at all. Part of the infrastructure to do this is recognizing
that auth/smart is indeed a smart-http repo.
The current apache config recognizes only "^/smart/*" as
smart-http. Let's instead treat anything with /smart/ in the
URL as smart-http. This is obviously a stupid thing to do
for a real production site, but for our test suite we know
that our repositories will not have this magic string in the
name.
Note that we will route /foo/smart/bar.git directly to
git-http-backend/bar.git; in other words, everything before
the "/smart/" is irrelevant to finding the repo on disk (but
may impact apache config, for example by triggering auth
checks).

Our test apache config points all of auth/ directly to the
on-disk repositories via an Alias directive. This works fine
because everything authenticated is currently in auth/dumb,
which is a subset. However, this would conflict with a
ScriptAlias for auth/smart (which will come in future
patches), so let's narrow the Alias.

The t5550 script sets up a nice askpass helper for
simulating user input and checking what git prompted for.
Let's make it available to other http scripts by migrating
it to lib-httpd.
We can use this immediately in t5540 to make our tests more
robust (previously, we did not check at all that hitting the
password-protected repo actually involved a password).
Unfortunately, we end up failing the test because the
current code erroneously prompts twice (once for
git-remote-http, and then again when the former spawns
git-http-push).
More importantly, though, it will let us easily add
smart-http authentication tests in t5541 and t5551; we
currently do not test smart-http authentication at all.
As part of making it generic, let's always look for and
store auxiliary askpass files at the top-level trash
directory; this makes it compatible with t5540, which runs
some tests from sub-repositories. We can abstract away the
ugliness with a short helper function.

In most of our tests, we put repos to be accessed by dumb
protocols in /dumb, and repos to be accessed by smart
protocols in /smart. In our test apache setup, the whole
/auth hierarchy requires authentication. However, we don't
bother to split it by smart and dumb here because we are not
currently testing smart-http authentication at all.
That will change in future patches, so let's be explicit
that we are interested in testing dumb access here. This
also happens to match what t5540 does for the push tests.

Back when "git apply" was written, we made sure that the user can
skip more than the default number of path components (i.e. 1) by
giving "-p<n>", but the logic for doing so was built around the
notion of "we skip N slashes and stop". This obviously does not
work well when running under -p0 where we do not want to skip any,
but still want to skip SP/HT that separates the pathnames of
preimage and postimage and want to reject absolute pathnames.
Stop using "stop_at_slash()", and instead introduce a new helper
"skip_tree_prefix()" with similar logic but works correctly even for
the -p0 case.
This is an ancient bug, but has been masked for a long time because
most of the patches are text and have other clues to tell us the
name of the preimage and the postimage.
