a2036d7e00 git_connect(): use common return point
Use only one return point from git_connect(), doing the

    free();
    return conn;

only at one place in the code.

There may be a little confusion what the variable "host" is for.  At
some places it is only the host part, at other places it may include
the port number, so change host into hostandport here.

c59ab2e52a connect.c: refactor url parsing
Make the function is_local() in transport.c public, rename it into
url_is_local_not_ssh() and use it in both transport.c and connect.c

Use a protocol "local" for URLs for the local file system.

One note about using file:// under Windows:

The (absolute) path on Unix like system typically starts with "/".
When the host is empty, it can be omitted, so that a shell scriptlet
url=file://$pwd
will give a URL like "file:///home/user/repo".

Windows does not have the same concept of a root directory located in "/".
When parsing the URL allow "file://C:/user/repo"
(even if RFC1738 indicates that "file:///C:/user/repo" should be used).

6a59974869 git fetch: support host:/~repo
The documentation (in urls.txt) says that

    "ssh://host:/~repo",
    "host:/~repo" or
    "host:~repo"

specify the repository "repo" in the home directory at "host".

This has not been working for "host:/~repo".

Before commit 356bec "Support [address] in URLs", the comparison
"url != hostname" could be used to determine if the URL had a scheme
or not: "ssh://host/host" != "host".

However, after 356bec "[::1]" was converted into "::1", yielding
url != hostname as well.  To fix this regression, don't use
"if (url != hostname)", but look at the separator instead.

Rename the variable "c" into "separator" to make it easier to read.

5610b7c0c6 git fetch-pack: add --diag-url
The main purpose is to trace the URL parser called by git_connect() in
connect.c

The main features of the parser can be listed as this:

- parse out host and path for URLs with a scheme (git:// file:// ssh://)
- parse host names embedded by [] correctly
- extract the port number, if present
- separate URLs like "file" (which are local)
  from URLs like "host:repo" which should use ssh

Add the new parameter "--diag-url" to "git fetch-pack", which prints
the value for protocol, host and path to stderr and exits.

d98d109979 git_connect: remove artificial limit of a remote command
Since day one, function git_connect() had a limit on the command line of
the command that is invoked to make a connection. 7a33bcbe converted the
code that constructs the command to strbuf. This would have been the
right time to remove the limit, but it did not happen. Remove it now.

git_connect() uses start_command() to invoke the command; consequently,
the limits of the system still apply, but are diagnosed only at execve()
time. But these limits are more lenient than the 1K that git_connect()
imposed.

62f162f8e7 rev-parse: be more careful with munging arguments
When rev-parse looks at whether an argument like "foo..bar" or
"foobar^@" is a difference or parent-shorthand, it internally
munges the arguments so that it can pass the individual rev
arguments to get_sha1(). However, we do not consistently un-munge
the result.

For cases where we do not match (e.g., "doesnotexist..HEAD"), we
would then want to try to treat the argument as a filename.
try_difference gets() this right, and always unmunges in this case.
However, try_parent_shorthand() never unmunges, leading to incorrect
error messages, or even incorrect results:

  $ git rev-parse foobar^@
  foobar
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar^@
  foobar

For cases where we do match, neither function unmunges. This does
not currently matter, since we are done with the argument. However,
a future patch will do further processing, and this prepares for
it. In addition, it's simply a confusing interface for some cases to
modify the const argument, and others not to.

After a86a8b9 (sb/parseopt-boolean-removal), the deprecated
OPT_BOOLEAN is not used anywhere except by OPT__* macros. Kill
OPT_BOOLEAN and make OPT__* use OPT_COUNTUP directly instead. This
should stop OPT_BOOLEAN from entering the tree again in new patches.

OPT__DRY_RUN() is converted to use OPT_BOOL though because it does not
make sense to increase the level of dryness. All OPT__DRY_RUN call
sites have been checked and they look safe for OPT_BOOL.

1418567381 rev-parse: correctly diagnose revision errors before "--"
Rev-parse understands that a "--" may separate revisions and
filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).

Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way).  However, we misdiagnose
the errors:

  $ git rev-parse foobar -- >/dev/null
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar -- >/dev/null
  fatal: bad flag '--' used after filename

In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

83786fa412 config: arbitrary number of matches for --unset and --replace-all
git-config used a static match array to hold the matches we want to
unset/replace when using --unset or --replace-all.  Use a
variable-sized array instead.

This in particular fixes the symptoms git-svn had when storing large
numbers of svn-remote.*.added-placeholder entries in the config file.

While the tests are rather more paranoid than just --unset and
--replace-all, the other operations already worked.  Indeed git-svn's
usage only breaks the first time *after* creating so many entries,
when it wants to unset and re-add them all.

1a72cfd7fa commit -v: strip diffs and submodule shortlogs from the commit message
When using the '-v' option of "git commit" the diff added to the commit
message temporarily for editing is stripped off after the user exited the
editor by searching for "\ndiff --git " and truncating the commmit message
there if it is found.

But this approach has two problems:

- when the commit message itself contains a line starting with
  "diff --git" it will be truncated there prematurely; and

- when the "diff.submodule" setting is set to "log", the diff may
  start with "Submodule <hash1>..<hash2>", which will be left in
  the commit message while it shouldn't.

Fix that by introducing a special scissor separator line starting with the
comment character ('#' or the core.commentChar config if set) followed by
two lines describing what it is for. The scissor line - which will not be
translated - is used to reliably detect the start of the diff so it can be
chopped off from the commit message, no matter what the user enters there.

Turn a known test failure fixed by this change into a successful test;
also add one for a diff starting with a submodule log and another one for
proper handling of the comment char.

956623157f strbuf: introduce starts_with() and ends_with()
prefixcmp() and suffixcmp() share the common "cmp" suffix that
typically are used to name functions that can be used for ordering,
but they can't, because they are not antisymmetric:

        prefixcmp("foo", "foobar") < 0
        prefixcmp("foobar", "foo") == 0

We in fact do not use these functions for ordering.  Replace them
with functions that just check for equality.

Add starts_with() and end_with() that will be used to replace
prefixcmp() and suffixcmp(), respectively, as the first step.  These
are named after corresponding functions/methods in programming
languages, like Java, Python and Ruby.

In vcs-svn/fast_export.c, there was already an ends_with() function
that did the same thing. Let's use the new one instead while at it.

3fb5aead29 builtin/remote: remove postfixcmp() and use suffixcmp() instead
Commit 8cc5b290 (git merge -X<option>, 25 Nov 2009) introduced
suffixcmp() with nearly the same implementation as postfixcmp()
that already existed since commit 211c8968 (Make git-remote a
builtin, 29 Feb 2008).

The only difference between the two implementations is that,
when the string is smaller than the suffix, one implementation
returns 1 while the other one returns -1.

But, as postfixcmp() is only used to compare for equality, the
distinction does not matter and does not affect the correctness of
this patch.

As postfixcmp() has always been static in builtin/remote.c
and is used nowhere else, it makes more sense to remove it
and use suffixcmp() instead in builtin/remote.c, rather than
to remove suffixcmp().

86cd8dc8e7 Merge branch 'jh/loose-object-dirs-creation-race'
When two processes created one loose object file each, which fell
into the same fan-out bucket that previously did not have any
objects, they both tried to do an equivalent of

    mkdir .git/objects/$fanout &&
    chmod $shared_perm .git/objects/$fanout

before writing into their file .git/objects/$fanout/$remainder,
one of which could have failed unnecessarily when the second
invocation of mkdir found that the directory already has been
created by the first one.

b2a0afd96a Merge branch 'ak/submodule-foreach-quoting'
A behavior change, but a worthwhile one: "git submodule foreach"
was treating its arguments as part of a single command to be
concatenated and passed to a shell, making writing buggy
scripts too easy.

This patch preserves the old "just pass it to the shell" behavior
when a single argument is passed to 'git submodule foreach' and
moves to a new "skip the shell and use the arguments passed
unmolested" behavior when more than one argument is passed.

The old behavior (always concatenating and passing to the shell)
was similar to the 'ssh' command, while the new behavior (switching
on the number of arguments) is what 'xterm -e' does.

May need more thought to make sure this change is advertised well
so that scripts that used multiple arguments but added their own
extra layer of quoting are not broken.

* ak/submodule-foreach-quoting:
  submodule foreach: skip eval for more than one argument

96174145fc t5000: simplify gzip prerequisite checks
In t5000, we test the built-in ".tar.gz" config for
git-archive. To make our tests portable, we check that we
have a way to both gzip and gunzip, and we respected
environment variables to point to alternate commands for
doing these operations.

However, the $GZIP variable did not actually do anything, as
changing it would not affect the baked-in value in
archive-tar.c. Moreover, setting the variable $GZIP
influences gzip itself. From the gzip man page:

  The environment variable GZIP can hold a set of default
  options for gzip. These options are interpreted first and
  can be overwritten by explicit command line parameters.

We could rename this variable, and use it to set up custom
config (or even have a Makefile knob to affect the built
binary), but it is not worth the trouble; nobody has ever
reported a problem with the baked-in default, and they can
always change it via config if they need to. Let's just drop
the variable and use "gzip" in the test (keeping the
prerequisite, of course).

While we're at it, we can drop the GUNZIP variable and
prerequisite; it uses "gzip -d", so if we have GZIP, we
will have both.

We can also use test_lazy_prereq for the gzip prerequisite,
which is simpler and behaves more consistently with the rest
of git (e.g., by making output available when the test is
run with "-v").

9c0495d23e gettext.c: detect the vsnprintf bug at runtime
Bug 6530 [1] in glibc causes "git show v0.99.6~1" to fail with error
"your vsnprintf is broken". The workaround avoids that, but it
corrupts system error messages in non-C locales.

The bug has been fixed since 2.17. We could know running glibc version
with gnu_get_libc_version(). But version is not a sure way to detect
the bug because downstream may back port the fix to older versions. Do
a runtime test that immitates the call flow that leads to "your
vsnprintf is broken". Only enable the workaround if the test fails.

Tested on Gentoo Linux, glibc 2.16.0 and 2.17, amd64.

2171f3d2aa t5601: add tests for ssh
Add more tests testing all the combinations:

 -IPv4 or IPv6
 -path starting with "/" or with "/~"
 -with and without the ssh:// scheme

Some tests fail; they need updates in connect.c
