When gitweb is used as a DirectoryIndex, it attempts to strip
PATH_INFO on its own, as $cgi->url() fails to do so.
However, it fails to account for the fact that PATH_INFO has
already been URL-decoded by the web server, but the value
returned by $cgi->url() has not been. This causes the stripping
to fail whenever the URL contains encoded characters.
To see this in action, setup gitweb as a DirectoryIndex and
then use it on a repository with a directory containing a
space in the name. Navigate to tree view, examine the gitweb
generated html and you'll see a link such as:
<a href="/test.git/tree/HEAD:/directory with spaces">directory with spaces</a>
When clicked on, the browser will URL-encode this link, giving
a $cgi->url() of the form:
/test.git/tree/HEAD:/directory%20with%20spaces
While PATH_INFO is:
/test.git/tree/HEAD:/directory with spaces
Fix this by calling unescape() on both $my_url and $my_uri before
stripping PATH_INFO from them.

Various subcommands of the "git submodule" command exited with 0
status even though the path given by the user did not exist.
The reason behind that was that they all pipe the output of
module_list into the while loop which then does the action on the
paths specified by the commandline. Since the exit code of the
command on the upstream side of the pipe is ignored by the shell,
the status code of "ls-files --error-unmatch" nor "module_list" was
not propagated.
In case ls-files returns with an error code, we write a special
string that is not possible in non error situations, and no other
output, so that the downstream can detect the error and die with an
error code.
The error message that there is an unmatched pathspec comes through
stderr directly from ls-files. So the user still gets a hint whats going
on.

Many scripted Porcelains rely on being able to split words at the
default $IFS characters, i.e. SP, HT and LF. If the user exports a
non-default IFS to the environment, what they read from plumbing
commands such as ls-files that use HT to delimit fields may not be
split in the way we expect.
Protect outselves by resetting it, just like we do so against CDPATH

When asciidoc converts a listing block like:
----------------------
$ git log --merge
----------------------
it marks it to be displayed in a monospace font. This works
fine when generating HTML output. However, when generating
docbook output, we override the expansion of a listingblock
to work around bugs in some versions of the docbook
toolchain. Our override did not mark the listingblock with
the "monospaced" class.
The main output that uses docbook as an intermediate format
is the manpages. We didn't notice any issue there because
the monospaced class seems to be ignored when generating
roff from the docbook manpages.
However, when generating texinfo to make info pages, docbook
does respect this class. The resulting texinfo output
properly uses "@example" blocks to display the listing in
this case. Besides possibly looking prettier in some texinfo
backends, one important effect is that the monospace font
suppresses texinfo's expansion of "--" and "---" into
en-dashes and em-dashes. With the current code, the example
above ends up looking like "git log -merge", which is
confusing and wrong.

The standard output channel of receive-pack is a structured protocol
channel, and subprocesses must never be allowed to leak anything

When receive-pack triggers 'git gc --auto' and 'git prune' is called to
remove a stale temporary object, 'git prune' prints an informational
message to stdout about the file that it will remove. Since this message
is written to stdout, it is sent back over the transport channel to the git
client which tries to interpret it as part of the pack protocol and then
promptly terminates with a complaint about a protocol error.
Introduce a test which exercises the auto-gc functionality of receive-pack
and demonstrates this breakage.

When a stdio stream is opened in update mode (e.g., "w+"),
the C standard forbids switching between reading or writing
without an intervening positioning function. Many
implementations are lenient about this, but Solaris libc
will flush the recently-read contents to the output buffer.
In this instance, that meant writing the non-echoed password
that the user just typed to the terminal.
Fix it by inserting a no-op fseek between the read and
write.
The opposite direction (writing followed by reading) is also
disallowed, but our intervening fflush is an acceptable
positioning function for that alternative.

We already purged it in b3431bc (Don't use seq in tests, not

in. They went unnoticed because they are in scripts that are not
run by default.
Replace them with test_seq that is implemented with a Perl snippet
(proposed by Jeff). This is better than inlining this snippet
everywhere it's needed because it's easier to read and it's easier
to change the implementation (e.g. to C) if we ever decide to remove
Perl from the test suite.
Note that test_seq is not a complete replacement for seq(1). It
just has what we need now, in addition that it makes it possible for
us to do something like "test_seq a m" if we wanted to in the
future.
There are also many places that do `for i in 1 2 3 ...` but I'm not sure
if it's worth converting them to test_seq. That would introduce running
more processes of Perl.

* It checks for a return value of 0 from write_in_full(), which cannot
happen: it returns this value only if count=0, but flush_buffer()
will never call write_in_full() in this case.

The RFC2047 unquoting, used to parse email addresses in From and Cc
headers, is broken in several ways:
* It erroneously substitutes ' ' for '_' in *the whole* header, even
outside the quoted field. [Noticed by Christoph.]
* It is too liberal in its matching, and happily matches the start
of one quoted chunk against the end of another, or even just
something that looks like such an end. [Noticed by Junio.]
* It fundamentally cannot cope with encodings that are not a
superset of ASCII, nor several (incompatible) encodings in the
same header.
This patch fixes the first two by doing a more careful decoding of
the outer quoting (e.g. "=AB" to represent an octet whose value is
0xAB). Fixing the fundamental issues is left for a future, more
intrusive, patch.

When you have a non-directory on your PATH, a funny thing happens:
$ PATH=$PATH:/bin/sh git foo
fatal: cannot exec 'git-foo': Not a directory?
Worse yet, as real commands always take precedence over aliases,
this behaviour interacts rather badly with them:
$ PATH=$PATH:/bin/sh git -c alias.foo=show git foo -s
fatal: cannot exec 'git-foo': Not a directory?
This is because an ENOTDIR error from the underlying execvp(2) is
reported back to the caller of our sane_execvp() wrapper as-is.
Translating it to ENOENT, just like the case where we _might_ have
the command in an unreadable directory, fixes it. Without an alias,
we would get
git: 'foo' is not a git command. See 'git --help'.
and we use the 'foo' alias when it is available, of course.
