bbfe5302d5 implement test_might_fail using a refactored test_must_fail
Add an (optional) first parameter "ok=<special case>" to test_must_fail
and return success for "<special case>". Add "success" as
"<special case>" and use it to implement "test_might_fail". This removes
redundancies in test-lib-function.sh.

You can pass multiple <special case> arguments divided by comma (e.g.
"test_must_fail ok=success,something")

4d2a3646d1 filter-branch: deal with object name vs. pathname ambiguity in tree-filter
'git filter-branch' fails complaining about an ambiguous argument, if
a tree-filter renames a path and the new pathname happens to match an
existing object name.

After the tree-filter has been applied, 'git filter-branch' looks for
changed paths by running:

  git diff-index -r --name-only --ignore-submodules $commit

which then, because of the lack of disambiguating double-dash, can't
decide whether to treat '$commit' as revision or path and errors out.

Add that disambiguating double-dash after 'git diff-index's revision
argument to make sure that '$commit' is interpreted as a revision.

7cb5f7c44d blame: fix object casting regression
Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.

After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.

Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.

b7638fed42 git-p4: clean up after p4 submit failure
When "p4 submit" command fails in P4Submit.applyCommit, the
workspace is left with the changes.  We already have code to revert
the changes to the workspace when the user decides to cancel
submission by aborting the editor that edits the change description,
and we should treat the "p4 submit" failure the same way.

Clean the workspace if p4_write_pipe raised SystemExit, so that the
user don't have to do it themselves.

c26f70ceb3 bash prompt: indicate dirty index even on orphan branches
__git_ps1() doesn't indicate dirty index while on an orphan branch.

To check the dirtiness of the index, __git_ps1() runs 'git diff-index
--cached ... HEAD', which doesn't work on an orphan branch,
because HEAD doesn't point to a valid commit.

Run 'git diff ... --cached' instead, as it does the right thing both
on valid and invalid HEAD, i.e. compares the index to the existing
HEAD in the former case and to the empty tree in the latter.  This
fixes the two failing tests added in the first commit of this series.

The dirtiness of the worktree is already checked with 'git diff' and
is displayed correctly even on an orphan branch.

a30d11ebdf bash prompt: test dirty index and worktree while on an orphan branch
There is only a single test exercising the dirty state indicator on an
orphan branch, and in that test neither the index nor the worktree are
dirty.

Add two failing tests to check the dirty state indicator while either
the index is dirty or while both the index and the worktree are dirty
on an orphan branch, and to show that the dirtiness of the index is
not displayed in these cases (the fourth combination, i.e. clean index
and dirty worktree are impossible on an orphan branch).  Update the
existing dirty state indicator on clean orphan branch test to match
the style of the two new tests, most importantly to use 'git checkout
--orphan' instead of cd-ing into a repository that just happens to be
empty and clean.

00ad6e3182 git-p4: work with a detached head
When submitting, git-p4 finds the current branch in
order to know if it is allowed to submit (configuration
"git-p4.allowSubmit").

On a detached head, detecting the branch would fail, and
git-p4 would report a cryptic error.

This change teaches git-p4 to recognise a detached head and
submit successfully.

b33a15b081 push: add recurseSubmodules config option
The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.

The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

17b7a83244 sendemail: teach git-send-email to dump alias names
Add an option "--dump-aliases" which changes the default behavior of
git-send-email. This mode will simply read the alias files configured by
sendemail.aliasesfile and sendemail.aliasfiletype and dump a list of all
configured aliases, one per line. The intended use case for this option
is the bash-completion script which will use it to autocomplete aliases
on the options which take addresses.

Add some tests for the new option using various alias file formats.

A possible future extension to the alias dump format could be done by
extending the --dump-aliases to take an optional argument defining the
format to display. This has not been done in this patch as no user of
this information has been identified.

0ca2972345 modernize t9300: mark here-doc words to ignore tab indentation

require that here-documents ignore the tab indentation. Prepare for
this change by marking the here-doc words accordingly. This does not

The change here is entirely automated with this perl command:

  perl -i -lpe 's/(cat.*<<) *((EOF|(EXPECT|INPUT)_END).*$)/$1-$2 &&/' t/t9300-fast-import.sh

i.e., inserts a dash between << and the EOF word (and removes blanks
that our style guide abhors) and appends the && that will become
necessary.

681390b3f6 t5813: avoid creating urls that break on cygwin
When passed an ssh:// url, git strips ssh://host from the url but does
not remove leading slashes from the path. So when this test used
ssh://remote//path/to/pwd, the path accessed by our fake SSH is
//path/to/pwd, which cygwin interprets as a UNC path, causing the test
to fail.

We may want to actually fix this in git itself, making it remove extra
slashes from urls before feeding them to transports or helpers, but
that's for another topic as it could cause regressions.

pre-push and post-rewrite, which read from standard input.
The same arguments for ignoring SIGPIPE apply.

348d4f2fc5 filter-branch: skip index read/write when possible
If the user specifies an index filter but not a tree filter,
filter-branch cleverly avoids checking out the tree
entirely. But we don't do the next level of optimization: if
you have no index or tree filter, we do not need to read the
index at all.

This can greatly speed up cases where we are only changing
the commit objects (e.g., cementing a graft into place).
Here are numbers from the newly-added perf test:

baf0a3e47d wt-status: avoid building bogus branch name with detached HEAD
If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.

Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case.  This fixes t7060 with --valgrind.

ec352401fb blame: test to describe use of blame --reverse --first-parent
Reverse blame can be used to locate removal of lines which does not
change adjacent lines. Such edits do not appear in non-reverse blame,
because the adjacent lines last changed commit is older history, before
the edit.

For a big and active project which uses topic branches, or analogous
feature, for example pull-requests, the history can contain many
concurrent branches, and even after an edit merged into the target
branch, there are still many (sometimes several tens or even hundreds)
topic branch which do not contain it:

 a0--a1-----*a2-*a3-a4...-*a100
 |\         /   /         /
 | b0-B1..bN   /         /
 |\           /         /
 | c0..   ..cN         /
 \                    /
  z0..            ..zN

Here, the '*'s mark the first parent in merge, and uppercase B1 - the
commit where the line being blamed for was removed. Since commits cN-zN
do not contain B1, they still have the line removed in B1, and
reverse blame can report that the last commit for the line was zN
(meaning that it was removed in a100). In fact it really does return
some very late commit, and this makes it unusable for finding the B1
commit.

The search could be done by blame --reverse --first-parent. For range
a0..a100 it would return a1, and then only one additional blame along
the a0..bN will return the desired commit b0. But combining --reverse
and --first-parent was forbidden in 95a4fb0eac, because incorrectly
specified range could produce unexpected and meaningless result.

Add test which describes the expected behavior of
`blame --reverse --first-parent` in the case described above.

9e468334b4 ref-filter: fallback on alphabetical comparison
In ref-filter.c the comparison of refs while sorting is handled by
cmp_ref_sorting() function. When sorting as per numerical values
(e.g. --sort=objectsize) there is no fallback comparison when both
refs hold the same value. This can cause unexpected results (i.e. the
order of listing refs with equal values cannot be pre-determined) as
pointed out by Johannes Sixt ($gmane/280117).

Hence, fallback to alphabetical comparison based on the refname
whenever the other criterion is equal.

A test in t3203 was expecting that branch-two sorts before HEAD, which
happened to be how qsort(3) on Linux sorted the array, but (1) that
outcome was not even guaranteed, and (2) once we start breaking ties
with the refname, "HEAD" should sort before "branch-two" so the
original expectation was inconsistent with the criterion we now use.

Update it to match the new world order, which we can now depend on
being stable.

cfe2d4be91 difftool: ignore symbolic links in use_wt_file
The caller is preparing a narrowed-down copy of the working tree and
this function is asked if the path should be included in that copy.
If we say yes, the path from the working tree will be either symlinked
or copied into the narrowed-down copy.

For any path that is a symbolic link, the caller later fixes up the
narrowed-down copy by unlinking the path and replacing it with a
regular file it writes out that mimics the way how "git diff"
compares symbolic links.

Let's answer "no, you do not want to copy/symlink the working tree
file" for all symbolic links from this function, as we know the
result will not be used because it will be overwritten anyway.

Incidentally, this also stops the function from feeding a symbolic
link in the working tree to hash-object, which is a wrong thing to
do to begin with. The link may be pointing at a directory, or worse
may be dangling (both would be noticed as an error).  Even if the
link points at a regular file, hashing the contents of a file that
is pointed at by the link is not correct (Git hashes the contents of
the link itself, not the pointee).

e34f80278e merge-file: clamp exit code to maximum 127
Git-merge-file is documented to return one of three exit
codes:

  - zero means the merge was successful

  - a negative number means an error occurred

  - a positive number indicates the number of conflicts

Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).

This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).

Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

39743cf554 rebase-i: work around Windows CRLF line endings
Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform.  We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.

This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.

Special case a lone CR and treat it the same way as an empty line to
work this around.

This patch (also) passes the test with Git for Windows, where the
issue was seen first.

72fac66bca merge: detect delete/modechange conflict
If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).

The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion.  In many cases that is a sane resolution, but
we should be punting to the user whenever there is any
question. So let's detect and treat this as a conflict (in
both strategies).

f78d1fe208 t6031: generalize for recursive and resolve strategies
This script tests the filemode handling of merge-recursive,
but we do not test the same thing for merge-resolve. Let's
generalize the script a little:

  1. Break out the setup steps for each test into a separate
     snippet.

  2. For each test, run it twice; once with "-s recursive"
     and once with "-s resolve". We can avoid repeating
     ourselves by adding a function.

  3. Since we have a nice abstracted function, we can make
     our tests more thorough by testing both directions
     (change on "ours" versus "theirs").

This improves our test coverage, and will make this the
place to add more tests related to merging mode changes.

29abb33978 add: simplify -u/-A without pathspec
Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory).  The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec.  At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".

The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be".  The parse_pathspec() then would give
us a pathspec that matches everything and all is well.

Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs).  The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.

When testing the untracked-cache, we previously assumed that checking

root directory as racily-dirty.  But sometimes, the checkout would
happen at 12345.999 seconds and the status at 12346.001 seconds,
meaning that the worktree's root directory would not be racily-dirty.
And since it was not truly dirty, occasionally the test would fail.
By making the root truly dirty, the test will always succeed.

710b4e8a16 t0027: improve test for not-normalized files
When a text file with mixed line endings is commited into the repo,
it is called "not normalized" (or NNO) in t0027.  The existing test
case using repoMIX did not fully test all combinations: (Especially
when core.autocrlf = true) Files with NL are not converted at
commit, but at checkout, so a warning NL->CRLF is given.  Files with
CRLF are not converted at all (so no warning will be given), unless
they are marked as "text" or "auto".

Remove repoMIX introduced in commit 8eeab92f02, and replace it with
a combination of NNO tests.

a5a4b3ff4d filter-branch: remove multi-line headers in msg filter
df062010 (filter-branch: avoid passing commit message through sed)
introduced a regression when filtering commits with multi-line headers,
if the header contains a blank line.  An example of this is a gpg-signed
commit:

  $ git cat-file commit signed-commit
  tree 3d4038e029712da9fc59a72afbfcc90418451630
  parent 110eac945dc1713b27bdf49e74e5805db66971f0
  author A U Thor <author@example.com> 1112912413 -0700

  gpgsig -----BEGIN PGP SIGNATURE-----

   pUsAnA+f3aMUsd9mNroloSmlOgL6jIMO
   =0Hgm
   -----END PGP SIGNATURE-----

  Adding gpg

As a consequence, "filter-branch --msg-filter cat" (which should leave the
commit message unchanged) spills the signature (after the internal blank
line) into the original commit message.

The reason is that although the signature is indented, making the line a
whitespace only line, the "read" call is splitting the line based on
the shell's IFS, which defaults to <space><tab><newline>.  The leading
space is consumed and $header_line is empty, causing the "skip header
lines" loop to exit.

The rest of the commit object is then re-used as the rewritten commit
message, causing the new message to include the signature of the
original commit.

Set IFS to an empty string for the "read" call, thus disabling the word
splitting, which causes $header_line to be set to the non-empty value ' '.
This allows the loop to fully consume the header lines before
emitting the original, intact commit message.

786b150c8d clone --dissociate: avoid locking pack files
When `git clone` is asked to dissociate the repository from the
reference repository whose objects were used, it is quite possible that
the pack files need to be repacked. In that case, the pack files need to
be deleted that were originally hard-links to the reference repository's
pack files.

On platforms where a file cannot be deleted if another process still
holds a handle on it, we therefore need to take pains to release all
pack files and indexes before dissociating.

This fixes https://github.com/git-for-windows/git/issues/446

The test case to demonstrate the breakage technically does not need to
be run on Linux or MacOSX. It won't hurt, either, though.

1db168ee97 rebase-i: loosen over-eager check_bad_cmd check
804098bb (git rebase -i: add static check for commands and SHA-1,
2015-06-29) tried to check all insns before running any in the todo
list, but it did so by implementing its own parser that is a lot
stricter than necessary.  We used to allow lines that are indented
(including comment lines), and we used to allow a whitespace between
the insn and the commit object name to be HT, among other things,
that are flagged as an invalid line by mistake.

Fix this by using the same tokenizer that is used to parse the todo
list file in the new check.

Whether it's a good thing to accept indented comments is
debatable (other commands like "git commit" do not accept them), but we
already accepted them in the past, and some people and scripts rely on
this behavior. Also, a line starting with space followed by a '#' cannot
have any meaning other than being a comment, hence it doesn't harm to
accept them as comments.

9c28390bda init: use strbufs to store paths
The init code predates strbufs, and uses PATH_MAX-sized
buffers along with many manual checks on intermediate sizes
(some of which make magic assumptions, such as that init
will not create a path inside .git longer than 50
characters).

We can simplify this greatly by using strbufs, which drops
some hard-to-verify strcpy calls in favor of git_path_buf.
While we're in the area, let's also convert existing calls
to git_path to the safer git_path_buf (our existing calls
were passed to pretty tame functions, and so were not a
problem, but it's easy to be consistent and safe here).

Note that we had an explicit test that "git init" rejects
long template directories. This comes from 32d1776 (init: Do
not segfault on big GIT_TEMPLATE_DIR environment variable,
2009-04-18). We can drop the test_must_fail here, as we now
accept this and need only confirm that we don't segfault,
which was the original point of the test.

a5db4b127b git-p4: add support for large file systems
Perforce repositories can contain large (binary) files. Migrating these
repositories to Git generates very large local clones. External storage
systems such as Git LFS [1], Git Fat [2], Git Media [3], git-annex [4]
try to address this problem.

Add a generic mechanism to detect large files based on extension,
uncompressed size, and/or compressed size.

0eb8548f45 status: don't say 'HEAD detached at HEAD'
After using "git checkout --detach", the reflog is left with an entry
like

  checkout: moving from ... to HEAD

This message is parsed to generate the 'HEAD detached at' message in
'git branch' and 'git status', which leads to the not-so-useful message
'HEAD detached at HEAD'.

Instead, when parsing such reflog entry, resolve HEAD to the
corresponding commit in the reflog, so that the message becomes 'HEAD
detached at $sha1'.

1f5fbe1fe2 enter_repo: allow .git files in strict mode
Strict mode is about not guessing where .git is. If the user points to a
.git file, we know exactly where the target .git dir will be. This makes
it possible to serve .git files as repository on the server side.

This may be needed even in local clone case because transport.c code
uses upload-pack for fetching remote refs. But right now the
clone/transport code goes with non-strict.

b258116462 http: limit redirection depth
By default, libcurl will follow circular http redirects
forever. Let's put a cap on this so that somebody who can
trigger an automated fetch of an arbitrary repository (e.g.,
for CI) cannot convince git to loop infinitely.

The value chosen is 20, which is the same default that
Firefox uses.

f4113cac0c http: limit redirection to protocol-whitelist
Previously, libcurl would follow redirection to any protocol
it was compiled for support with. This is desirable to allow
redirection from HTTP to HTTPS. However, it would even
successfully allow redirection from HTTP to SFTP, a protocol
that git does not otherwise support at all. Furthermore
git's new protocol-whitelisting could be bypassed by
following a redirect within the remote helper, as it was
only enforced at transport selection time.

This patch limits redirects within libcurl to HTTP, HTTPS,
FTP and FTPS. If there is a protocol-whitelist present, this
list is limited to those also allowed by the whitelist. As
redirection happens from within libcurl, it is impossible
for an HTTP redirect to a protocol implemented within
another remote helper.

When the curl version git was compiled with is too old to
support restrictions on protocol redirection, we warn the
user if GIT_ALLOW_PROTOCOL restrictions were requested. This
is a little inaccurate, as even without that variable in the
environment, we would still restrict SFTP, etc, and we do
not warn in that case. But anything else means we would
literally warn every time git accesses an http remote.

This commit includes a test, but it is not as robust as we
would hope. It redirects an http request to ftp, and checks
that curl complained about the protocol, which means that we
are relying on curl's specific error message to know what
happened. Ideally we would redirect to a working ftp server
and confirm that we can clone without protocol restrictions,
and not with them. But we do not have a portable way of
providing an ftp server, nor any other protocol that curl
supports (https is the closest, but we would have to deal
with certificates).

31cd128372 t/perf: make runner work even if Git is not installed
aggregate.perl did not work when Git.pm is not installed to a directory
contained in the default Perl library path list or PERLLIB.
This commit prepends the Perl library path of the current Git source
tree to enable this.

Note that this commit adds a hard-coded relative path

  use lib '../../perl/blib/lib';

instead of the flexible environment-based variant

  use lib (split(/:/, $ENV{GITPERLLIB}));

which is used in tests written in Perl.
The hard-coded variant is used because the whole performance test
framework does it that way (and GITPERLLIB is not set there).

df1ed03a6f remote-ext: simplify git pkt-line generation
We format a pkt-line into a heap buffer, which requires
manual computation of the required size, and uses some bare
sprintf calls. We could use a strbuf instead, which would
take care of the computation for us. But it's even easier
still to use packet_write(). Besides handling the formatting
and writing for us, it fixes two things:

  1. Our manual max-size check used 0xFFFF, while technically
     LARGE_PACKET_MAX is slightly smaller than this.

  2. Our packet will now be output as part of
     GIT_TRACE_PACKET debugging.

Unfortunately packet_write() does not let us build up the
buffer progressively, so we do have to repeat ourselves a
little depending on the "vhost" setting, but the end result
is still far more readable than the original.

Since there were no tests covering this feature at all,
we'll add a few into t5802.

495127dbcb resolve_ref: use strbufs for internal buffers
resolve_ref already uses a strbuf internally when generating
pathnames, but it uses fixed-size buffers for storing the
refname and symbolic refs. This means that you cannot
actually point HEAD to a ref that is larger than 256 bytes.

We can lift this limit by using strbufs here, too. Like
sb_path, we pass the the buffers into our helper function,
so that we can easily clean up all output paths. We can also
drop the "unsafe" name from our helper function, as it no
longer uses a single static buffer (but of course
resolve_ref_unsafe is still unsafe, because the static
buffers moved there).

As a bonus, we also get to drop some strcpy calls between
the two fixed buffers (that cannot currently overflow
because the two buffers are sized identically).

aedcb7dc75 branch.c: use 'ref-filter' APIs
Make 'branch.c' use 'ref-filter' APIs for iterating through refs
sorting. This removes most of the code used in 'branch.c' replacing it
with calls to the 'ref-filter' library.

Make 'branch.c' use the 'filter_refs()' function provided by 'ref-filter'
to filter out tags based on the options set.

We provide a sorting option provided for 'branch.c' by using the
sorting options provided by 'ref-filter'. Also by default, we sort by
'refname'.  Since 'HEAD' is alphabatically before 'refs/...' we end up
with an array consisting of the 'HEAD' ref then the local branches and
finally the remote-tracking branches.

Also remove the 'ignore' variable from ref_array_item as it was
previously used for the '--merged' option and now that is handled by
ref-filter.

Modify some of the tests in t1430 to check the stderr for a warning
regarding the broken ref. This is done as ref-filter throws a warning
for broken refs rather than directly printing them.

Add tests and documentation for the same.

362d8b6e0d t5561: get rid of racy appending to logfile
The definition of log_div() appended information to the web server's
logfile to make the test more readable. However, log_div() was called
right after a request is served (which is done by git-http-backend);
the web server waits for the git-http-backend process to exit before
it writes to the log file. When the duration between serving a request
and exiting was long, the log_div() output was written before the last
request's log, and the test failed. (This duration could become
especially long for PROFILE=GEN builds.)

To get rid of this behavior, we should not change the logfile at all.
This commit removes log_div() and its calls. The additional information
is kept in the test (for readability reasons) but filtered out before
comparing it to the actual logfile.

33cfccbbf3 submodule: allow only certain protocols for submodule fetches
Some protocols (like git-remote-ext) can execute arbitrary
code found in the URL. The URLs that submodules use may come
from arbitrary sources (e.g., .gitmodules files in a remote
repository). Let's restrict submodules to fetching from a
known-good subset of protocols.

Note that we apply this restriction to all submodule
commands, whether the URL comes from .gitmodules or not.
This is more restrictive than we need to be; for example, in
the tests we run:

  git submodule add ext::...

which should be trusted, as the URL comes directly from the
command line provided by the user. But doing it this way is
simpler, and makes it much less likely that we would miss a
case. And since such protocols should be an exception
(especially because nobody who clones from them will be able
to update the submodules!), it's not likely to inconvenience
anyone in practice.

a5adaced2e transport: add a protocol-whitelist environment variable
If we are cloning an untrusted remote repository into a
sandbox, we may also want to fetch remote submodules in
order to get the complete view as intended by the other
side. However, that opens us up to attacks where a malicious
user gets us to clone something they would not otherwise
have access to (this is not necessarily a problem by itself,
but we may then act on the cloned contents in a way that
exposes them to the attacker).

Ideally such a setup would sandbox git entirely away from
high-value items, but this is not always practical or easy
to set up (e.g., OS network controls may block multiple
protocols, and we would want to enable some but not others).

We can help this case by providing a way to restrict
particular protocols. We use a whitelist in the environment.
This is more annoying to set up than a blacklist, but
defaults to safety if the set of protocols git supports
grows). If no whitelist is specified, we continue to default
to allowing all protocols (this is an "unsafe" default, but
since the minority of users will want this sandboxing
effect, it is the only sensible one).

A note on the tests: ideally these would all be in a single
test file, but the git-daemon and httpd test infrastructure
is an all-or-nothing proposition rather than a test-by-test
prerequisite. By putting them all together, we would be
unable to test the file-local code on machines without
apache.

1f5f390711 git-p4: handle "Translation of file content failed"
A P4 repository can get into a state where it contains a file with
type UTF-16 that does not contain a valid UTF-16 BOM. If git-p4
attempts to retrieve the file then the process crashes with a
"Translation of file content failed" error.

More info here: http://answers.perforce.com/articles/KB/3117

Fix this by detecting this error and retrieving the file as binary
instead. The result in Git is the same.

Known issue: This works only if git-p4 is executed in verbose mode.
In normal mode no exceptions are thrown and git-p4 just exits.
