e5ea66f9e5 gitweb: Make i18n (encoding) tests in t9500 leave clean state
The most important issue is that after unsetting `i18n.commitencoding'
config variable t9500 no longer will use author and comitter name
containing ISO-8859-1 characters, which are invalid UTF-8 characters.

Besides it is good practice in general to clean up the state in tests.

e832f43c1d vcs-svn: add binary-safe read function
buffer_read_string works well for non line-oriented input except for
one problem: it does not tell the caller how many bytes were actually
written.  This means that unless one is very careful about checking
for errors (and eof) the calling program cannot tell the difference
between the string "foo" followed by an early end of file and the
string "foo\0bar\0baz".

So introduce a variant that reports the length, too, a thinner wrapper
around strbuf_fread.  Its result is written to a strbuf so the caller
does not need to keep track of the number of bytes read.

d280f68313 t0081 (line-buffer): add buffering tests
POSIX makes the behavior of read(2) from a pipe fairly clear: a read
from an empty pipe will block until there is data available and any
other read will not block, prefering to return a partial result.
Likewise, fread(3) and fgets(3) are clearly specified to act as
though implemented by calling fgetc(3) in a simple loop.  But the
buffering behavior of fgetc is less clear.

Luckily, no sane platform is going to implement fgetc by calling the
equivalent of read(2) more than once.  fgetc has to be able to
return without filling its buffer to preserve errno when errors are
encountered anyway.  So let's assume the simpler behavior (trust) but
add some tests to catch insane platforms that violate that when they
come (verify).

First check that fread can handle a 0-length read from an empty fifo.
Because open(O_RDONLY) blocks until the writing end is open, open the
writing end of the fifo in advance in a subshell.

Next try short inputs from a pipe that is not filled all the way.

Lastly (two tests) try very large inputs from a pipe that will not fit
in the relevant buffers.  The first of these tests reads a little
more than 8192 bytes, which is BUFSIZ (the size of stdio's buffers)
on this Linux machine.  The second reads a little over 64 KiB (the
pipe capacity on Linux) and is not run unless requested by setting
the GIT_REMOTE_SVN_TEST_BIG_FILES environment variable.

8dc6a373d2 fast-import: add 'ls' command
Lazy fast-import frontend authors that want to rely on the backend to
keep track of the content of the imported trees _almost_ have what
they need in the 'cat-blob' command (v1.7.4-rc0~30^2~3, 2010-11-28).
But it is not quite enough, since

 (1) cat-blob can be used to retrieve the content of files, but
     not their mode, and

 (2) using cat-blob requires the frontend to keep track of a name
     (mark number or object id) for each blob to be retrieved

Introduce an 'ls' command to complement cat-blob and take care of the
remaining needs.  The 'ls' command finds what is at a given path
within a given tree-ish (tag, commit, or tree):

	'ls' SP <dataref> SP <path> LF

or in fast-import's active commit:

	'ls' SP <path> LF

The response is a single line sent through the cat-blob channel,
imitating ls-tree output.  So for example:

	FE> ls :1 Documentation
	gfi> 040000 tree 9e6c2b599341d28a2a375f8207507e0a2a627fe9	Documentation
	FE> ls 9e6c2b599341d28a2a375f8207507e0a2a627fe9 git-fast-import.txt
	gfi> 100644 blob 4f92954396e3f0f97e75b6838a5635b583708870	git-fast-import.txt
	FE> ls :1 RelNotes
	gfi> 120000 blob b942e49944	RelNotes
	FE> cat-blob b942e49944
	gfi> b942e49944 blob 32
	gfi> Documentation/RelNotes/1.7.4.txt

The most interesting parts of the reply are the first word, which is
a 6-digit octal mode (regular file, executable, symlink, directory,
or submodule), and the part from the second space to the tab, which is
a <dataref> that can be used in later cat-blob, ls, and filemodify (M)
commands to refer to the content (blob, tree, or commit) at that path.

If there is nothing there, the response is "missing some/path".

The intent is for this command to be used to read files from the
active commit, so a frontend can apply patches to them, and to copy
files and directories from previous revisions.

For example, proposed updates to svn-fe use this command in place of
its internal representation of the repository directory structure.
This simplifies the frontend a great deal and means support for
resuming an import in a separate fast-import run (i.e., incremental
import) is basically free.

2169ddc056 Disallow empty section and variable names
It is possible to break your repository config by creating an invalid key.  The
config parser in turn chokes on it:

  $ git init
  Initialized empty Git repository in /tmp/gittest/.git/
  $ git config .foo false
  $ git config core.bare
  fatal: bad config file line 6 in .git/config

This patch makes git-config reject keys which start or end with a dot and adds
tests for these cases.

b09c53a3e3 Sanity-check config variable names
Sanity-check config variable names when adding and retrieving them.  As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.

This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

49151d8b2c t/gitweb-lib.sh: Ensure that errors are shown for --debug --immediate
Because '--immediate' stops test suite after first error, therefore in
this mode

  test_debug 'cat gitweb.log'

was never ran, thus in effect negating effect of '--debug' option.
This made finidng the cause of errors in gitweb test sute difficult.

Modify the gitweb_run test subroutine to run test_debug itself in the
case of errors (and also remove "test_debug 'cat gitweb.log'" from
gitweb tests).

This makes it possible to run *gitweb tests* with --immediate ---debug
combination of options; also it makes gitweb tests to not output
spurious debug data that is not considered error.

They are stored in %xx notation, and when checked out, p4
converts them back to normal.

This patch does the same thing when importing into git,
converting the four special characters.  Without this change,
the files appear with literal %xx in their names.

Be careful not to produce "*" in filenames on windows.  That

a902618792 clone: die when trying to clone missing local path
Since 86ac751 (Allow cloning an empty repository,
2009-01-23), doing:

  git clone does-not-exist

has created does-not-exist as an empty repository. This was
an unintentional side effect of 86ac751. Even weirder,
doing:

  git clone does-not-exist new-dir

_does_ fail, making this "feature" (if you want to consider
it such) broken. Let's detect this situation and explicitly
die. It's almost certainly not what the user intended.

This patch also adds two tests. One for the missing path
case, and one to confirm that a similar case, cloning a
non-repository directory, fails.

339e5638b0 tests: skip terminal output tests on OS X
On Mac OS X 10.5.0, test_terminal gets stuck reading from the pty
master every once in a while.  To reproduce the problem:

 perl -MIO::Pty -MFile::Copy -e '
	for (my $i = 0;; $i++) {
		my $master = new IO::Pty;
		my $slave = $master->slave;
		if (fork == 0) {
			close $master or die "close: $!";
			open STDOUT, ">&", $slave or die "dup2: $!";
			close $slave or die "close: $!";
			exec("echo", "hi", $i) or die "exec: $!";
		}
		close $slave or die "close: $!";
		copy($master, \*STDOUT) or die "copy: $!";
		close $master or die "close: $!";
		wait;
	}
 '

It blocks after 7000 iterations or so in sysread().  The relevant
sysread() call is the second call by the parent, which presumably
executes before the child dies but after the parent has read all
output from there.

Since this is an intermitent problem, the quick check of terminal
support in lib-terminal doesn't catch it.  Skip these tests on the Mac
for now.

2f59c94704 mergetool: don't skip modify/remove conflicts
Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.

Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.

 file1: file does not need merging
 Continue merging other unresolved paths (y/n) ?

Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was
introduced in the previous commit.

48d9e6ae4b perl: command_bidi_pipe() method should set-up git environmens
When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.

command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up.  Because of this, a program that did this
did not work as expected:

    my $repo = Git->repository(Directory => '/some/where/else');
    my ($pid, $in, $out, $ctx) =
    $repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));

This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.

Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

547e8b9205 fast-import: introduce "feature notes" command
Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.

When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.

Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op.  On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like

	This version of fast-import does not support feature notes.

So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes.  (This would be especially important for backends that
do not support rewinding history after a botched import.)
