Jeff King 99094a7ad4 t: fix trivial &&-chain breakage
These are tests which are missing a link in their &&-chain,
but during a setup phase. We may fail to notice failure in
commands that build the test environment, but these are
typically not expected to fail at all (but it's still good
to double-check that our test environment is what we
expect).

Jeff King 8fb268720e t: fix severe &&-chain breakage
These are tests which are missing a link in their &&-chain,
in a location which causes a significant portion of the test
to be missed (e.g., the test effectively does nothing, or
consists of a long string of actions and output comparisons,
and we throw away the exit code of at least one part of the
string).

Junio C Hamano c5558f80c3 fetch: allow explicit --refmap to override configuration
Since the introduction of opportunisitic updates of remote-tracking
branches, started at around f2690487 (fetch: opportunistically
update tracking refs, 2013-05-11) with a few updates in v1.8.4 era,
the remote.*.fetch configuration always kicks in even when a refspec
to specify what to fetch is given on the command line, and there is
no way to disable or override it per-invocation.

Teach the command to pay attention to the --refmap=<lhs>:<rhs>
command-line options that can be used to override the use of
configured remote.*.fetch as the refmap.

Carlos Martín Nieto e6f637122e fetch: handle overlaping refspecs on --prune
We need to consider that a remote-tracking branch may match more than
one rhs of a fetch refspec. In such a case, it is not enough to stop at
the first match but look at all of the matches in order to determine
whether a head is stale.

To this goal, introduce a variant of query_refspecs which returns all of
the matching refspecs and loop over those answers to check for
staleness.

Sebastian Schuberth ab58289eff t5510: Do not use $(pwd) when fetching / pushing / pulling via rsync
On MINGW, "pwd" is defined as "pwd -W" in test-lib.sh. This usually is the
right thing, but the absolute Windows path with a colon confuses rsync. We
could use $PWD in this case to work around the issue, but in fact there is
no need to use an absolute path in the first place, so get rid of it.

This was discovered in the context of the mingwGitDevEnv project and only
did not surface before with msysgit because the latter does not ship
rsync.

Carlos Martín Nieto f377e7a37c fetch: add a failing test for prunning with overlapping refspecs
When a remote has multiple fetch refspecs and these overlap in the
target namespace, fetch may prune a remote-tracking branch which still
exists in the remote. The test uses a popular form of this, by putting
pull requests as stored in a popular hosting platform alongside "real"
remote-tracking branches.

The fetch command makes a decision of whether to prune based
on the first matching refspec, which in this case is insufficient, as it
covers the pull request names. This pair of refspecs does work as
expected if the more "specific" refspec is the first in the list.

Jeff King 4c22408111 fetch-pack: do not filter out one-level refs
Currently fetching a one-level ref like "refs/foo" does not
work consistently. The outer "git fetch" program filters the
list of refs, checking each against check_refname_format.
Then it feeds the result to do_fetch_pack to actually
negotiate the haves/wants and get the pack. The fetch-pack
code does its own filter, and it behaves differently.

The fetch-pack filter looks for refs in "refs/", and then
feeds everything _after_ the slash (i.e., just "foo") into
check_refname_format.  But check_refname_format is not
designed to look at a partial refname. It complains that the
ref has only one component, thinking it is at the root
(i.e., alongside "HEAD"), when in reality we just fed it a
partial refname.

As a result, we omit a ref like "refs/foo" from the pack
request, even though "git fetch" then tries to store the
resulting ref.  If we happen to get the object anyway (e.g.,
because the ref is contained in another ref we are
fetching), then the fetch succeeds. But if it is a unique
object, we fail when trying to update "refs/foo".

We can fix this by just passing the whole refname into
check_refname_format; we know the part we were omitting is
"refs/", which is acceptable in a refname. This at least
makes the checks consistent with each other.

This problem happens most commonly with "refs/stash", which
is the only one-level ref in wide use. However, our test
does not use "refs/stash", as we may later want to restrict
it specifically (not because it is one-level, but because
of the semantics of stashes).

We may also want to do away with the multiple levels of
filtering (which can cause problems when they are out of
sync), or even forbid one-level refs entirely. However,
those decisions can come later; this fixes the most
immediate problem, which is the mismatch between the two.

Tom Miller 10a6cc8890 fetch --prune: Run prune before fetching
When we have a remote-tracking branch named "frotz/nitfol" from a
previous fetch, and the upstream now has a branch named "frotz",
fetch would fail to remove "frotz/nitfol" with a "git fetch --prune"
from the upstream. git would inform the user to use "git remote
prune" to fix the problem.

Change the way "fetch --prune" works by moving the pruning operation
before the fetching operation. This way, instead of warning the user
of a conflict, it autmatically fixes it.

Michael Haggerty 0838bf47b3 fetch --prune: prune only based on explicit refspecs
The old behavior of "fetch --prune" was to prune whatever was being
fetched.  In particular, "fetch --prune --tags" caused tags not only
to be fetched, but also to be pruned.  This is inappropriate because
there is only one tags namespace that is shared among the local
repository and all remotes.  Therefore, if the user defines a local
tag and then runs "git fetch --prune --tags", then the local tag is
deleted.  Moreover, "--prune" and "--tags" can also be configured via
fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it
even less obvious that an invocation of "git fetch" could result in
tag lossage.

Since the command "git remote update" invokes "git fetch", it had the
same problem.

The command "git remote prune", on the other hand, disregarded the
setting of remote.<name>.tagopt, and so its behavior was inconsistent
with that of the other commands.

So the old behavior made it too easy to lose tags.  To fix this
problem, change "fetch --prune" to prune references based only on
refspecs specified explicitly by the user, either on the command line
or via remote.<name>.fetch.  Thus, tags are no longer made subject to
pruning by the --tags option or the remote.<name>.tagopt setting.

However, tags *are* still subject to pruning if they are fetched as
part of a refspec, and that is good.  For example:

* On the command line,

      git fetch --prune 'refs/tags/*:refs/tags/*'

  causes tags, and only tags, to be fetched and pruned, and is
  therefore a simple way for the user to get the equivalent of the old
  behavior of "--prune --tag".

* For a remote that was configured with the "--mirror" option, the
  configuration is set to include

      [remote "name"]
              fetch = +refs/*:refs/*

  , which causes tags to be subject to pruning along with all other
  references.  This is the behavior that will typically be desired for
  a mirror.

Michael Haggerty c5a84e92a2 fetch --tags: fetch tags *in addition to* other stuff
Previously, fetch's "--tags" option was considered equivalent to
specifying the refspec "refs/tags/*:refs/tags/*" on the command line;
in particular, it caused the remote.<name>.refspec configuration to be
ignored.

But it is not very useful to fetch tags without also fetching other
references, whereas it *is* quite useful to be able to fetch tags *in
addition to* other references.  So change the semantics of this option
to do the latter.

If a user wants to fetch *only* tags, then it is still possible to
specifying an explicit refspec:

    git fetch <remote> 'refs/tags/*:refs/tags/*'

Please note that the documentation prior to 1.8.0.3 was ambiguous
about this aspect of "fetch --tags" behavior.  Commit

    f0cb2f137c 2012-12-14 fetch --tags: clarify documentation

made the documentation match the old behavior.  This commit changes
the documentation to match the new behavior.

Michael Haggerty 68a304d5fe t5510: check that "git fetch --prune --tags" does not prune branches
"git fetch --prune --tags" is currently interpreted as follows:

* "--tags" is equivalent to specifying a refspec
  "refs/tags/*:refs/tags/*", and supersedes any default refspecs
  configured via remote.$REMOTE.fetch.

* "--prune" only operates on the refspecs being fetched.

Therefore, "git fetch --prune --tags" prunes tags in refs/tags/* but
does not fetch or prune other references.  The fact that this command
does not prune references outside of refs/tags/* was previously
untested.  So add a test that verifies the status quo.

However, the status quo is surprising, so it will be changed later in
this patch series.

Michael Haggerty d0d06e892a t5510: prepare test refs more straightforwardly
"git fetch" was being used with contrived refspecs to create tags and
remote-tracking branches in test repositories in preparation for the
actual tests.  This is obscure and also makes one wonder whether this
is indeed just preparation or whether some side-effect of "git fetch"
is being tested.

So use the more straightforward commands "git tag" / "git update-ref"
when preparing branches in test repositories.

"git fetch" that honors remote.*.prune is fine, but I wonder if we

"push", "fetch", "both"?

Michael Schubert 737c5a9cde fetch: make --prune configurable
Without "git fetch --prune", remote-tracking branches for a branch
the other side already has removed will stay forever.  Some people
want to always run "git fetch --prune".

To accommodate users who want to either prune always or when fetching
from a particular remote, add two new configuration variables
"fetch.prune" and "remote.<name>.prune":

 - "fetch.prune" allows to enable prune for all fetch operations.

 - "remote.<name>.prune" allows to change the behaviour per remote.

The latter will naturally override the former, and the --[no-]prune
option from the command line will override the configured default.

Since --prune is a potentially destructive operation (Git doesn't
keep reflogs for deleted references yet), we don't want to prune
without users consent, so this configuration will not be on by
default.

Jeff King f269048754 fetch: opportunistically update tracking refs
When we run a regular "git fetch" without arguments, we
update the tracking refs according to the configured
refspec. However, when we run "git fetch origin master" (or
"git pull origin master"), we do not look at the configured
refspecs at all, and just update FETCH_HEAD.

We miss an opportunity to update "refs/remotes/origin/master"
(or whatever the user has configured). Some users find this
confusing, because they would want to do further comparisons
against the old state of the remote master, like:

  $ git pull origin master
  $ git log HEAD...origin/master

In the currnet code, they are comparing against whatever
commit happened to be in origin/master from the last time
they did a complete "git fetch".  This patch will update a
ref from the RHS of a configured refspec whenever we happen
to be fetching its LHS. That makes the case above work.

The downside is that any users who really care about whether
and when their tracking branches are updated may be
surprised.

We have three sequential tests for for whether tracking refs
are updated by various fetches and pulls; the first two
should not update the ref, and the third should. Each test

This is fragile (a failing early test will confuse later
tests), and means we cannot add more "should update" tests
after the third one.

Let's instead save the initial state before these tests, and
then reset to a known state before running each test.

Thomas Rast efe4be1249 bundle: keep around names passed to add_pending_object()
The 'name' field passed to add_pending_object() is used to later
deduplicate in object_array_remove_duplicates().

git-bundle had a bug in this area since 18449ab (git-bundle: avoid
packing objects which are in the prerequisites, 2007-03-08): it passed
the name of each boundary object in a static buffer.  In other words,
all that object_array_remove_duplicates() saw was the name of the
*last* added boundary object.

The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan
the log for boundary commits, 2012-02-22) made this slightly worse: we
now free the buffer at the end, so it is not even guaranteed that it
still points into addressable memory by the time object_array_remove_
duplicates looks at it.  On the plus side however, it was now
detectable by valgrind.

The fix is easy: pass a copy of the string to add_pending_object.

Joey Hess 96890f4c42 write first for-merge ref to FETCH_HEAD first
The FETCH_HEAD refname is supposed to refer to the ref that was fetched
and should be merged. However all fetched refs are written to
.git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply
takes the first ref as the FETCH_HEAD, which is often the wrong one,
when other branches were also fetched.

The solution is to write the for-merge ref(s) to FETCH_HEAD first.
Then, unless --append is used, the FETCH_HEAD refname behaves as intended.
If the user uses --append, they presumably are doing so in order to
preserve the old FETCH_HEAD.

While we are at it, update an old example in the read-tree documentation
that implied that each entry in FETCH_HEAD only has the object name, which
is not true for quite a while.

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".

When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.

Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.

So for the same reason as we added rule to allow "git fetch $there v1.0"
instead of "git fetch $there tags/v1.0" in the previous commit, here is a
bit longer rope for the users, which incidentally simplifies our code.

Carlos Martín Nieto ed43de6ec3 fetch: honor the user-provided refspecs when pruning refs
If the user gave us refspecs on the command line, we should use those
when deciding whether to prune a ref instead of relying on the
refspecs in the config.

Previously, running

    git fetch --prune origin refs/heads/master:refs/remotes/origin/master

would delete every other ref under the origin namespace because we
were using the refspec to filter the available refs but using the
configured refspec to figure out if a ref had been deleted on the
remote. This is clearly the wrong thing to do.

Change prune_refs and get_stale_heads to simply accept a list of
references and a list of refspecs. The caller of either function needs
to decide what refspecs should be used to decide whether a ref is
stale.

Brandon Casey 042cca3886 t/t5510-fetch.sh: improve testing with explicit URL and merge spec
Commit 6106ce46 introduced a test to demonstrate fetch's failure to
retrieve any objects or update FETCH_HEAD when it was supplied a repository
URL and the current branch had a configured merge spec.  This commit
expands the original test based on comments from Junio Hamano.  In addition
to actually verifying that the fetch updates FETCH_HEAD correctly, and does
not update the current branch, two more tests are added to ensure that the
merge configuration is ignored even when the supplied URL matches the URL
of the remote configured for the branch.

Jonathan Nieder 18a8269242 tests: subshell indentation stylefix
Format the subshells introduced by the previous patch (Several tests:
cd inside subshell instead of around, 2010-09-06) like so:

	(
		cd subdir &&
		...
	) &&

This is generally easier to read and has the nice side-effect that
this patch will show what commands are used in the subshell, making
it easier to check for lost environment variables and similar
behavior changes.

Brandon Casey 3ee1757bae builtin/fetch.c: ignore merge config when not fetching from branch's remote
When 'git fetch' is supplied a single argument, it tries to match it
against a configured remote and then fetch the refs specified by the
named remote's fetchspec.  Additionally, or alternatively, if the current
branch has a merge ref configured, and if the name of the remote supplied
to fetch matches the one in the branch's configuration, then git also adds
the merge ref to the list of refs to update.

If the argument to fetch does not specify a named remote, or if the name
supplied does not match the remote configured for the current branch, then
the current branch's merge configuration should not be considered.

git currently mishandles the case when the argument to fetch specifies a
GIT URL(i.e. not a named remote) and the current branch has a configured
merge ref.  In this case, fetch should ignore the branch's merge ref and
attempt to fetch from the remote repository's HEAD branch.  But, since
fetch only checks _whether_ the current branch has a merge ref configured,
and does _not_ check whether the branch's configured remote matches the
command line argument (until later), it will mistakenly enter the wrong
branch of an 'if' statement and will not fall back to fetch the HEAD branch.
The fetch ends up doing nothing and returns with a successful zero status.

Fix this by comparing the remote repository's name to the branch's remote
name, in addition to whether it has a configured merge ref, sooner, so that
fetch can correctly decide whether the branch's configuration is interesting
or not, and fall back to fetching from the remote's HEAD branch when
appropriate.

This fixes the test in t5510.

Brandon Casey 6106ce4669 t/t5510: demonstrate failure to fetch when current branch has merge ref
When 'git fetch' is supplied just a repository URL (not a remote name),
and without a fetch refspec, it should fetch from the remote HEAD branch
and update FETCH_HEAD with the fetched ref.  Currently, when 'git fetch'
is called like this, it fails to retrieve anything, and does not update
FETCH_HEAD, if the current checked-out branch has a configured merge ref.

i.e. this fetch fails to retrieve anything nor update FETCH_HEAD:

   git checkout master
   git config branch.master.merge refs/heads/master
   git fetch git://git.kernel.org/pub/scm/git/git.git

but this one does:

   git config --unset branch.master.merge
   git fetch git://git.kernel.org/pub/scm/git/git.git

Add a test to demonstrate this flaw.

Gary V. Vaughan 4fdf71be1c tests: use "test_cmp", not "diff", when verifying the result
In tests, call test_cmp rather than raw diff where possible (i.e. if
the output does not go to a pipe), to allow the use of, say, 'cmp'
when the default 'diff -u' is not compatible with a vendor diff.

When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS.

Julian Phillips 95c96d48e6 remote: fix use-after-free error detected by glibc in ref_remove_duplicates
In ref_remove_duplicates, when we encounter a duplicate and remove it
from the list we need to make sure that the prev pointer stays
pointing at the last entry and also skip over adding the just freed
entry to the string_list.

Previously fetch could crash with:
*** glibc detected *** git: corrupted double-linked list: ...

Also add a test to try and catch problems with duplicate removal in
the future.

Johannes Schindelin 7efaeba2a8 rsync transport: allow local paths, and fix tests
Earlier, the rsync tests were disabled by default, as they needed a
running rsyncd daemon.  This was only due to the limitation that our
rsync transport only allowed full URLs of the form

	rsync://<host>/<path>

Relaxing the URLs to allow

	rsync:<path>

permitted the change in the tests to run whenever rsync is available,
without requiring a fully configured and running rsyncd.

While at it, the tests were fixed so that they run in directories with a
space in their name.

Johannes Schindelin 8ee5d73137 Fix fetch/pull when run without --update-head-ok
Some confusing tutorials suggested that it would be a good idea to fetch
into the current branch with something like this:

	git fetch origin master:master

(or even worse: the same command line with "pull" instead of "fetch").
While it might make sense to store what you want to pull, it typically is
plain wrong when the current branch is "master".  This should only be
allowed when (an incorrect) "git pull origin master:master" tries to work
around by giving --update-head-ok to underlying "git fetch", and otherwise
we should refuse it, but somewhere along the lines we lost that behavior.

The check for the current branch is now _only_ performed in non-bare
repositories, which is an improvement from the original behaviour.

Some newer tests were depending on the broken behaviour of "git fetch"
this patch fixes, and have been adjusted.
