When two or more branches point at the same commit and HEAD is
pointing at one of them, without the symref extension, there is no
way to remotely tell which one of these branches HEAD points at.
The test in question attempts to make sure that this situation is
diagnosed and results in a failure.
However, even if there _were_ a way to reliably tell which branch
the HEAD points at, "set-head --auto" would fail if there is no
remote tracking branch. Make sure that this test does not fail
for that "wrong" reason.

There is no reason not to turn on keepalives by default.
They take very little bandwidth, and significantly less than
the progress reporting they are replacing. And in the case
that progress reporting is on, we should never need to send
a keepalive anyway, as we will constantly be showing
progress and resetting the keepalive timer.
We do not necessarily know what the client's idea of a
reasonable timeout is, so let's keep this on the low side of
5 seconds. That is high enough that we will always prefer
our normal 1-second progress reports to sending a keepalive
packet, but low enough that no sane client should consider

When upload-pack has started pack-objects, there may be a quiet
period while pack-objects prepares the pack (i.e., counting objects
and delta compression). Normally we would see (and send to the
client) progress information, but if "--quiet" is in effect,
pack-objects will produce nothing at all until the pack data is
ready. On a large repository, this can take tens of seconds (or even
minutes if the system is loaded or the repository is badly packed).
Clients or intermediate proxies can sometimes give up in this
situation, assuming that the server or connection has hung.
This patch introduces a "keepalive" option; if upload-pack sees no
data from pack-objects for a certain number of seconds, it will send
an empty sideband data packet to let the other side know that we are
still working on it.

When creating an upstream relationship, we use the configured remotes and
their refspecs to determine the upstream configuration settings
branch.<name>.remote and branch.<name>.merge. However, if the matching
refspec does not have refs/heads/<something> on the remote side, we end
up rejecting the match, and failing the upstream configuration.
It could be argued that when we set up an branch's upstream, we want that
upstream to also be a proper branch in the remote repo. Although this is
typically the common case, there are cases (as demonstrated by the previous
patch in this series) where this requirement prevents a useful upstream
relationship from being formed. Furthermore:
- We have fundamentally no say in how the remote repo have organized its
branches. The remote repo may put branches (or branch-like constructs
that are insteresting for downstreams to track) outside refs/heads/*.
- The user may intentionally want to track a non-branch from a remote
repo, by using a branch and configured upstream in the local repo.
Relaxing the checking to only require a matching remote/refspec allows the
testcase introduced in the previous patch to succeed, and has no negative
effect on the rest of the test suite.
This patch fixes a behavior (arguably a regression) first introduced in
41c21f2 (branch.c: Validate tracking branches with refspecs instead of
refs/remotes/*) on 2013-04-21 (released in >= v1.8.3.2).

In 41c21f2 (branch.c: Validate tracking branches with refspecs instead of
refs/remotes/*), we changed the rules for what is considered a valid tracking
branch (a.k.a. upstream branch). We now use the configured remotes and their
refspecs to determine whether a proposed tracking branch is in fact within
the domain of a remote, and we then use that information to deduce the
upstream configuration (branch.<name>.remote and branch.<name>.merge).
However, with that change, we also check that - in addition to a matching
refspec - the result of mapping the tracking branch through that refspec
(i.e. the corresponding ref name in the remote repo) happens to start with
"refs/heads/". In other words, we require that a tracking branch refers to
a _branch_ in the remote repo.
Now, consider that you are e.g. setting up an automated building/testing
infrastructure for a group of similar "source" repositories. The build/test
infrastructure consists of a central scheduler, and a number of build/test
"slave" machines that perform the actual build/test work. The scheduler
monitors the group of similar repos for changes (e.g. with a periodic
"git fetch"), and triggers builds/tests to be run on one or more slaves.
Graphically the changes flow between the repos like this:
Source #1 -------v ----> Slave #1
/
Source #2 -----> Scheduler -----> Slave #2
\
Source #3 -------^ ----> Slave #3
... ...
The scheduler maintains a single Git repo with each of the source repos set
up as distinct remotes. The slaves also need access to all the changes from
all of the source repos, so they pull from the scheduler repo, but using the
following custom refspec:
remote.origin.fetch = "+refs/remotes/*:refs/remotes/*"
This makes all of the scheduler's remote-tracking branches automatically
available as identical remote-tracking branches in each of the slaves.
Now, consider what happens if a slave tries to create a local branch with
one of the remote-tracking branches as upstream:
git branch local_branch --track refs/remotes/source-1/some_branch
Git now looks at the configured remotes (in this case there is only "origin",
pointing to the scheduler's repo) and sees refs/remotes/source-1/some_branch
matching origin's refspec. Mapping through that refspec we find that the
corresponding remote ref name is "refs/remotes/source-1/some_branch".
However, since this remote ref name does not start with "refs/heads/", we
discard it as a suitable upstream, and the whole command fails.
This patch adds a testcase demonstrating this failure by creating two
source repos ("a" and "b") that are forwarded through a scheduler ("c")
to a slave repo ("d"), that then tries create a local branch with an
upstream. See the next patch in this series for the exciting conclusion
to this story...

We're testing that trying to --track a ref that is not covered by any remote

refs/remotes/local/master (so that the tracking setup will fail, as intended).
However, when doing "git fetch local" to ensure the existence of
refs/remotes/local/master, we must not already have changed remote.local.fetch
so as to cause refs/remotes/local/master not to be fetched. Therefore, set
remote.local.fetch to refs/heads/*:refs/remotes/local/* BEFORE we fetch, and
then reset it to refs/heads/s:refs/remotes/local/s AFTER we have fetched
(but before we test --track).

When we read a sha1 file, we first look for a packed
version, then a loose version, and then re-check the pack
directory again before concluding that we cannot find it.
This lets us handle a process that is writing to the
repository simultaneously (e.g., receive-pack writing a new
pack followed by a ref update, or git-repack packing
existing loose objects into a new pack).
However, we do not do the same trick with has_sha1_file; we
only check the packed objects once, followed by loose
objects. This means that we might incorrectly report that we
do not have an object, even though we could find it if we
simply re-checked the pack directory.
By itself, this is usually not a big deal. The other process
is running simultaneously, so we may run has_sha1_file
before it writes, anyway. It is a race whether we see the
object or not. However, we may also see other things
the writing process has done (like updating refs); and in
that case, we must be able to also see the new objects.
For example, imagine we are doing a for_each_ref iteration,
and somebody simultaneously pushes. Receive-pack may write
the pack and update a ref after we have examined the
objects/pack directory, but before the iteration gets to the
updated ref. When we do finally see the updated ref,
for_each_ref will call has_sha1_file to check whether the
ref is broken. If has_sha1_file returns the wrong answer, we
erroneously will think that the ref is broken.
For a normal iteration without DO_FOR_EACH_INCLUDE_BROKEN,
this means that the caller does not see the ref at all
(neither the old nor the new value). So not only will we
fail to see the new value of the ref (which is acceptable,
since we are running simultaneously with the writer, and we
might well read the ref before the writer commits its
write), but we will not see the old value either. For
programs that act on reachability like pack-objects or
prune, this can cause data loss, as we may see the objects
referenced by the original ref value as dangling (and either
omit them from the pack, or delete them via prune).
There's no test included here, because the success case is
two processes running simultaneously forever. But you can
replicate the issue with:
# base.sh
# run this in one terminal; it creates and pushes
# repeatedly to a repository
git init parent &&
(cd parent &&
# create a base commit that will trigger us looking at
# the objects/pack directory before we hit the updated ref
echo content >file &&
git add file &&
git commit -m base &&
# set the unpack limit abnormally low, which
# lets us simulate full-size pushes using tiny ones
git config receive.unpackLimit 1
) &&
git clone parent child &&
cd child &&
n=0 &&
while true; do
echo $n >file && git add file && git commit -m $n &&
git push origin HEAD:refs/remotes/child/master &&
n=$(($n + 1))
done
# fsck.sh
# now run this simultaneously in another terminal; it
# repeatedly fscks, looking for us to consider the
# newly-pushed ref broken. We cannot use for-each-ref
# here, as it uses DO_FOR_EACH_INCLUDE_BROKEN, which
# skips the has_sha1_file check (and if it wants
# more information on the object, it will actually read
# the object, which does the proper two-step lookup)
cd parent &&
while true; do
broken=`git fsck 2>&1 | grep remotes/child`
if test -n "$broken"; then
echo $broken
exit 1
fi
done
Without this patch, the fsck loop fails within a few seconds
(and almost instantly if the test repository actually has a
large number of refs). With it, the two can run
indefinitely.

The read_mailmap_buf function reads each line of the mailmap
using strchrnul, like:
const char *end = strchrnul(buf, '\n');
unsigned long linelen = end - buf + 1;
But that's off-by-one when we actually hit the NUL byte; our
line does not have a terminator, and so is only "end - buf"
bytes long. As a result, when we subtract the linelen from
the total len, we end up with (unsigned long)-1 bytes left
in the buffer, and we start reading random junk from memory.
We could fix it with:
unsigned long linelen = end - buf + !!*end;
but let's take a step back for a moment. It's questionable
in the first place for a function that takes a buffer and
length to be using strchrnul. But it works because we only
have one caller (and are only likely to ever have this one),
which is handing us data from read_sha1_file. Which means
that it's always NUL-terminated.
Instead of tightening the assumptions to make the
buffer/length pair work for a caller that doesn't actually
exist, let's let loosen the assumptions to what the real
caller has: a modifiable, NUL-terminated string.
This makes the code simpler and shorter (because we don't
have to correlate strchrnul with the length calculation),
correct (because the code with the off-by-one just goes
away), and more efficient (we can drop the extra allocation
we needed to create NUL-terminated strings for each line,
and just terminate in place).

The purpose of edge commits is to let pack-objects know what objects
it can use as base, but does not need to include in the thin pack
because the other side is supposed to already have them. So far we
mark uninteresting parents of interesting commits as edges. But even
an unrelated uninteresting commit (that the other side has) may
become a good base for pack-objects and help produce more efficient
packs.
This is especially true for shallow clone, when the client issues a
fetch with a depth smaller or equal to the number of commits the
server is ahead of the client. For example, in this commit history
the client has up to "A" and the server has up to "B":
-------A---B
have--^ ^
/
want--+
If depth 1 is requested, the commit list to send to the client
includes only B. The way m_e_u is working, it checks if parent
commits of B are uninteresting, if so mark them as edges. Due to
shallow effect, commit B is grafted to have no parents and the
revision walker never sees A as the parent of B. In fact it marks no
edges at all in this simple case and sends everything B has to the
client even if it could have excluded what A and also the client
already have.
In a slightly different case where A is not a direct parent of B
(iow there are commits in between A and B), marking A as an edge can
still save some because B may still have stuff from the far ancestor
A.
There is another case from the earlier patch, when we deepen a ref
from C->E to A->E:
---A---B C---D---E
want--^ ^ ^
shallow-+ /
have-------+
In this case we need to send A and B to the client, and C (i.e. the
current shallow point that the client informs the server) is a very
good base because it's closet to A and B. Normal m_e_u won't recognize
C as an edge because it only looks back to parents (i.e. A<-B) not the
opposite way B->C even if C is already marked as uninteresting commit
by the previous patch.
This patch includes all uninteresting commits from command line as
edges and lets pack-objects decide what's best to do. The upside is we
have better chance of producing better packs in certain cases. The
downside is we may need to process some extra objects on the server
side.
For the shallow case on git.git, when the client is 5 commits behind
and does "fetch --depth=3", the result pack is 99.26 KiB instead of
4.92 MiB.

According to C99, section 7.1.4:
Any function declared in a header may be additionally
implemented as a function-like macro defined in the
header.
Therefore calling our struct member function pointer "fgetc"
may run afoul of unwanted macro expansion when we call:
char c = cf->fgetc(cf);
This turned out to be a problem on uclibc, which defines
fgetc as a macro and causes compilation failure.
The standard suggests fixing this in a few ways:
1. Using extra parentheses to inhibit the function-like
macro expansion. E.g., "(cf->fgetc)(cf)". This is
undesirable as it's ugly, and each call site needs to
remember to use it (and on systems without the macro,
forgetting will compile just fine).
2. Using #undef (because a conforming implementation must
also be providing fgetc as a function). This is
undesirable because presumably the implementation was
using the macro for a performance benefit, and we are
dropping that optimization.
Instead, we can simply use non-colliding names.

fetch_pack() can remove .git/shallow file when a shallow repository
becomes a full one again. This behavior is triggered incorrectly when
tags are also fetched because fetch_pack() will be called twice. At
the first fetch_pack() call:
- shallow_lock is set up
- alternate_shallow_file points to shallow_lock.filename, which is
"shallow.lock"
- commit_lock_file is called, which sets shallow_lock.filename to "".
alternate_shallow_file also becomes "" because it points to the
same memory.
At the second call, setup_alternate_shallow() is not called and
alternate_shallow_file remains "". It's mistaken as unshallow case and
.git/shallow is removed. The end result is a broken repository.

to use the canonical name for the author found this way.
Fix it by telling the logic to find a matching existing author to
honor the mailmap, and use the name and email after applying the
mailmap.

directory_exists_in_index() takes pathname and its length, but its
helper function directory_exists_in_index_icase() reads one byte
beyond the end of the pathname and expects there to be a '/'.
This needs to be fixed, as that one-byte-beyond-the-end location may
not even be readable, possibly by not registering directories to
name hashes with trailing slashes. In the meantime, update the new
caller added recently to treat_one_path() to make sure that the path
buffer it gives the function is one byte longer than the path it is
asking the function about by appending a slash to it.

Old Bash (3.0) which is distributed with RHEL 4.X and other ancient
platforms that are still in wide use, do not have a printf that
supports -v. Neither does Zsh (which is already handled in the code).
As suggested by Junio, let's test whether printf supports the -v
option and store the result. Then later, we can use it to
determine whether 'printf -v' can be used, or whether printf
must be called in a subshell.

Old Bash (3.0) which is distributed with RHEL 4.X and other ancient
platforms that are still in wide use, does not understand the
array+=() notation. Let's use an explicit assignment to the new array
element which works everywhere, like:
array[${#array[@]}+1]=''
The right-hand side '' is not strictly necessary, but in this case
I think it is more clear.

The syntax for retrieving the number of elements in an array is:
${#name[@]}

When "merge.log" config is set, "rebase --preserve-merges" will add
the log lines to the message of the rebased merge commit. A rebase
should not modify a commit message automatically.
Teach "git-rebase" to ignore that configuration by passing
"--no-log" to the git-merge call.
