When we are parsing an integer or unsigned long, we use
the strto*max functions, which properly set errno to ERANGE
if we get a large value. However, we also do further range
checks after applying our multiplication factor, but do not
set ERANGE. This means that a caller cannot tell if an error
was caused by ERANGE or if the input was simply not a valid
number.
This patch teaches git_parse_signed and git_parse_unsigned to set
ERANGE for range errors, and EINVAL for other errors, so that the
caller can reliably tell these cases apart.

When we look at a config value as an integer using the
git_config_int function, we carefully range-check the value
we get and complain if it is out of our range. But the range
we compare to is that of a "long", which we then cast to an
"int" in the function's return value. This means that on
systems where "int" and "long" have different sizes (e.g.,
LP64 systems), we may pass the range check, but then return
nonsense by truncating the value as we cast it to an int.
We can solve this by converting git_parse_long into
git_parse_int, and range-checking the "int" range. Nobody
actually cared that we used a "long" internally, since the
result was truncated anyway. And the only other caller of
git_parse_long is git_config_maybe_bool, which should be
fine to just use int (though we will now forbid out-of-range
nonsense like setting "merge.ff" to "10g" to mean "true",
which is probably a good thing).

When we are parsing integers for config, we use an intmax_t
(or uintmax_t) internally, and then check against the size
of our result type at the end. We can parameterize the
maximum representable value, which will let us re-use the
parsing code for a variety of range checks.
Unfortunately, we cannot combine the signed and unsigned
parsing functions easily, as we have to rely on the signed
and unsigned C types internally.

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
refspec should fail. For that, we want to have refs/remotes/local/master
present, but we also want the remote.local.fetch refspec to NOT match
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).

2. (cd ../..; git grep foo)
3. for d in d1 d2 d3; do (cd $d && git svn rebase); done
The methods shown above are acceptable for scripting but are too
cumbersome for quick command line invocations.
With this new option, the above can be done with fewer keystrokes:

external projects and even the Python remote helpers in contrib/ don't
use this library, so it is only used by its own test suite.
Since this is the only Python library in Git, removing it will make

Pass a list of open bzrlib.transport.Transport objects to each bzrlib
function that might create a transport. This enables bzrlib to reuse
existing transports when possible, avoiding multiple concurrent
connections to the same remote server.
If the remote server is accessed via ssh, this fixes a couple of
problems:
* If the user does not have keys loaded into an ssh agent, the user
may be prompted for a password multiple times.
* If the user is using OpenSSH and the ControlMaster setting is set
to auto, git-remote-bzr might hang. This is because bzrlib closes
the multiple ssh sessions in an undefined order and might try to
close the master ssh session before the other sessions. The
master ssh process will not exit until the other sessions have
exited, causing a deadlock. (The ssh sessions are closed in an
undefined order because bzrlib relies on the Python garbage
collector to trigger ssh session termination.)

Historically, "git status" needed to prefix each output line with '#' so
that the output could be added as comment to the commit message. This
prefix comment has no real purpose when "git status" is ran from the
command-line, and this may distract users from the real content.
Disable this prefix comment by default, and make it re-activable for
users needing backward compatibility with status.displayCommentPrefix.

comment unconditionnaly when writing to COMMIT_EDITMSG (but not when
writing to stdout for an error message or with --dry-run).

Users replacing an object with one of a different type were not

To avoid mistakes, it is better to just forbid that though.
If -f option, which means '--force', is used, we can allow an object
to be replaced with one of a different type, as the user should know
what (s)he is doing.
If one object is replaced with one of a different type, the only way
to keep the history valid is to also replace all the other objects
that point to the replaced object. That's because:
* Annotated tags contain the type of the tagged object.
* The tree/parent lines in commits must be a tree and commits, resp.
* The object types referred to by trees are specified in the 'mode'
field:
100644 and 100755 blob
160000 commit
040000 tree
(these are the only valid modes)
* Blobs don't point at anything.

git-svn used in combination with serf to talk to svn repository

This is caused by a bug in serf, and the most recent serf release
1.3.1 still exhibits the problem; a fix for the bug exists (see

Until the bug is fixed, work around the issue within the git perl
module Ra.pm by freeing the private copy of the remote access object
on termination, which seems to be sufficient to prevent the error
from happening.
Note: Since subversion-1.8.0 and later do require serf-1.2.1 or

Not ignored are submodules that are added, deleted, or moved (which is

determine the old path once a move has occurred, nor is it easily possible to
