0e15ad9b73 add tests for cloning corrupted repositories
We try not to let corruption pass unnoticed over fetches and
clones. For the most part, this works, but there are some
broken corner cases, including:

  1. We do not detect missing objects over git-aware
     transports. This is a little hard to test, because the
     sending side will actually complain about the missing
     object.

     To fool it, we corrupt a repository such that we have a
     "misnamed" object: it claims to be sha1 X, but is
     really Y. This lets the sender blindly transmit it, but
     it is the receiver's responsibility to verify that what
     it got is sane (and it does not).

  2. We do not detect missing or misnamed blobs during the
     checkout phase of clone.

d9c31e14d0 streaming_write_entry: propagate streaming errors
When we are streaming an index blob to disk, we store the
error from stream_blob_to_fd in the "result" variable, and
then immediately overwrite that with the return value of
"close". That means we catch errors on close (e.g., problems
committing the file to disk), but miss anything which
happened before then.

We can fix this by using bitwise-OR to accumulate errors in
our result variable.

While we're here, we can also simplify the error handling
with an early return, which makes it easier to see under
which circumstances we need to clean up.

7b6257b0d4 add test for streaming corrupt blobs
We do not have many tests for handling corrupt objects. This
new test at least checks that we detect a byte error in a
corrupt blob object while streaming it out with cat-file.

e721c1544f checkout: avoid unnecessary match_pathspec calls
In checkout_paths() we do this

 - for all updated items, call match_pathspec
 - for all items, call match_pathspec (inside unmerge_cache)
 - for all items, call match_pathspec (for showing "path .. is unmerged)
 - for updated items, call match_pathspec and update paths

That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.

The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..

The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched.  Although
this should be considered a bug fix, not a regression. A new test is
added for this change.

And while at there, free ps_matched after use.

The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:

git checkout -- "*[a-zA-Z]*[a-zA-Z]*[a-zA-Z]*"

99d3206010 combine-diff: coalesce lost lines optimally
This replaces the greedy implementation to coalesce lost lines by using
dynamic programming to find the Longest Common Subsequence.

The O(n²) time complexity is obviously bigger than previous
implementation but it can produce shorter diff results (and most likely
easier to read).

List of lost lines is now doubly-linked because we reverse-read it when
reading the direction matrix.

cee683b72e t7600: use test_config to set/unset git config variables
Instead of using construct such as:
    test_when_finished "git config --unset <key>"
    git config <key> <value>
uses
    test_config <key> <value>
The latter takes care of removing <key> at the end of the test.

Tests are modified to assume default configuration at entry,
and to reset the modified configuration variables at the end.

Test 'merge log message' was relying on the presence of option `--no-ff`
in the configuration. With the option, git show -s --pretty=format:%b HEAD
produces an empty line and without the option, it produces an empty file.
The test is modified to check with and without `--no-ff` option.

c19d1b4e84 Fix revision walk for commits with the same dates
Logic in still_interesting function allows to stop the commits
traversing if the oldest processed commit is not older then the
youngest commit on the list to process and the list contains only
commits marked as not interesting ones. It can be premature when dealing
with a set of coequal commits. For example git rev-list A^! --not B
provides wrong answer if all commits in the range A..B had the same
commit time and there are more then 7 of them.

To fix this problem the relevant part of the logic in still_interesting
is changed to: the walk can be stopped if the oldest processed commit is
younger then the youngest commit on the list to processed.

250b3c6c99 apply --whitespace=fix: avoid running over the postimage buffer
Originally update-pre-post-images could assume that any whitespace
fixing will make the result only shorter by unexpanding runs of
leading SPs into HTs and removing trailing whitespaces at the end of
lines.  Updating the post-image we read from the patch to match the
actual result can be performed in-place under this assumption.
These days, however, we have tab-in-indent (aka Python) rule whose
result can be longer than the original, and we do need to allocate
a larger buffer than the input and replace the result.

Fortunately the support for lengthening rewrite was already added
when we began supporting "match while ignoring whitespace
differences" mode in 86c91f9179 (git apply: option to ignore
whitespace differences, 2009-08-04).  We only need to correctly
count the number of bytes necessary to hold the updated result and
tell the function to allocate a new buffer.

2ad23273e7 do not use GIT_TRACE_PACKET=3 in tests
Some test scripts use the GIT_TRACE mechanism to dump
debugging information to descriptor 3 (and point it to a
file using the shell). On Windows, however, bash is unable
to set up descriptor 3. We do not write our trace to the
file, and worse, we may interfere with other operations
happening on descriptor 3, causing tests to fail or even
behave inconsistently.

Prior to commit 97a83fa (upload-pack: remove packet debugging
harness), these tests used GIT_DEBUG_SEND_PACK, which only
supported output to a descriptor. The tests in t5503 were
always broken on Windows, and were marked to be skipped via
the NOT_MINGW prerequisite. In t5700, the tests used to pass
prior to 97a83fa, but only because they were not careful
enough; because we only grepped the trace file, an empty
file looked successful to us. But post-97a83fa, the writing
to descriptor 3 causes "git fetch" to hang (presumably
because we are throwing random bytes into the middle of the
protocol).

Now that we are using the GIT_TRACE mechanism, we can
improve both scripts by asking git to write directly to a
file rather than a descriptor. That fixes the hang in t5700,
and should allow t5503 to successfully run on Windows.

In both cases we now also use "test -s" to double-check that
our trace file actually contains output, which should reduce
the possibility of an erroneously passing test.

c29c46fa2e pack-refs: add fully-peeled trait
Older versions of pack-refs did not write peel lines for
refs outside of refs/tags. This meant that on reading the
pack-refs file, we might set the REF_KNOWS_PEELED flag for
such a ref, even though we do not know anything about its
peeled value.

The previous commit updated the writer to always peel, no
matter what the ref is. That means that packed-refs files
written by newer versions of git are fine to be read by both
old and new versions of git. However, we still have the
problem of reading packed-refs files written by older
versions of git, or by other implementations which have not
yet learned the same trick.

The simplest fix would be to always unset the
REF_KNOWS_PEELED flag for refs outside of refs/tags that do
not have a peel line (if it has a peel line, we know it is
valid, but we cannot assume a missing peel line means
anything). But that loses an important optimization, as
upload-pack should not need to load the object pointed to by
refs/heads/foo to determine that it is not a tag.

Instead, we add a "fully-peeled" trait to the packed-refs
file. If it is set, we know that we can trust a missing peel
line to mean that a ref cannot be peeled. Otherwise, we fall
back to assuming nothing.

03a8eddfd1 pack-refs: write peeled entry for non-tags
When we pack an annotated tag ref, we write not only the
sha1 of the tag object along with the ref, but also the sha1
obtained by peeling the tag. This lets readers of the
pack-refs file know the peeled value without having to
actually load the object, speeding up upload-pack's ref
advertisement.

The writer marks a packed-refs file with peeled refs using
the "peeled" trait at the top of the file. When the reader
sees this trait, it knows that each ref is either followed
by its peeled value, or it is not an annotated tag.

However, there is a mismatch between the assumptions of the
reader and writer. The writer will only peel refs under
refs/tags, but the reader does not know this; it will assume
a ref without a peeled value must not be a tag object. Thus
an annotated tag object placed outside of the refs/tags
hierarchy will not have its peeled value printed by
upload-pack.

The simplest way to fix this is to start writing peel values
for all refs. This matches what the reader expects for both
new and old versions of git.

06f15bf1f3 upload-pack: make sure "want" objects are parsed
When upload-pack receives a "want" line from the client, it
adds it to an object array. We call lookup_object to find
the actual object, which will only check for objects already
in memory. This works because we are expecting to find
objects that we already loaded during the ref advertisement.

We use the resulting object structs for a variety of
purposes. Some of them care only about the object flags, but
others care about the type of the object (e.g.,
ok_to_give_up), or even feed them to the revision parser
(when --depth is used), which assumes that objects it
receives are fully parsed.

Once upon a time, this was OK; any object we loaded into
memory would also have been parsed. But since 435c833
(upload-pack: use peel_ref for ref advertisements,
2012-10-04), we try to avoid parsing objects during the ref
advertisement. This means that lookup_object may return an
object with a type of OBJ_NONE. The resulting mess depends
on the exact set of objects, but can include the revision
parser barfing, or the shallow code sending the wrong set of
objects.

This patch teaches upload-pack to parse each "want" object
as we receive it. We do not replace the lookup_object call
with parse_object, as the current code is careful not to let
just any object appear on a "want" line, but rather only one
we have previously advertised (whereas parse_object would
actually load any arbitrary object from disk).

7297a44012 entry: fix filter lookup
When looking up the stream filter, write_entry() should be passing the
path of the file in the repository, not the path to which the content is
going to be written.  This allows the file to be correctly looked up
against the .gitattributes files in the working tree.

This change makes the streaming case match the non-streaming case which
passes ce->name to convert_to_working_tree later in the same function.

The two tests added here test the different paths through write_entry
since the CRLF filter is a streaming filter but the user-defined smudge
filter is not streamed.

02c56314aa difftool --dir-diff: symlink all files matching the working tree
Some users like to edit files in their diff tool when using "git
difftool --dir-diff --symlink" to compare against the working tree but
difftool currently only created symlinks when a file contains unstaged
changes.

Change this behaviour so that symlinks are created whenever the
right-hand side of the comparison has the same SHA1 as the file in the
working tree.

Note that textconv filters are handled in the same way as by git-diff
and if a clean filter is not the inverse of its smudge filter we already
get a null SHA1 from "diff --raw" and will symlink the file without
going through the new hash-object based check.

bbd848633e git p4: avoid expanding client paths in chdir
The generic chdir() helper sets the PWD environment
variable, as that is what is used by p4 to know its
current working directory.  Normally the shell would
do this, but in git-p4, we must do it by hand.

However, when the path contains a symbolic link,
os.getcwd() will return the physical location.  If the
p4 client specification includes symlinks, setting PWD
to the physical location causes p4 to think it is not
inside the client workspace.  It complains, e.g.

    Path /vol/bar/projects/foo/... is not under client root /p/foo

One workaround is to use AltRoots in the p4 client specification,
but it is cleaner to handle it directly in git-p4.

Other uses of chdir still require setting PWD to an
absolute path so p4 features like P4CONFIG work.  See
bf1d68f (git-p4: use absolute directory for PWD env
var, 2011-12-09).

bd54cf17a4 archive: handle commits with an empty tree
git-archive relies on get_pathspec to convert its argv into
a list of pathspecs. When get_pathspec is given an empty
argv list, it returns a single pathspec, the empty string,
to indicate that everything matches. When we feed this to
our path_exists function, we typically see that the pathspec
turns up at least one item in the tree, and we are happy.

But when our tree is empty, we erroneously think it is
because the pathspec is too limited, when in fact it is
simply that there is nothing to be found in the tree. This
is a weird corner case, but the correct behavior is almost
certainly to produce an empty archive, not to exit with an
error.

This patch teaches git-archive to create empty archives when
there is no pathspec given (we continue to complain if a
pathspec is given, since it obviously is not matched). It
also confirms that the tar and zip writers produce sane
output in this instance.

6cd3c05327 format-patch: RFC 2047 says multi-octet character may not be split
Even though an earlier attempt (bafc478..41dd00bad) cleaned
up RFC 2047 encoding, pretty.c::add_rfc2047() still decides
where to split the output line by going through the input
one byte at a time, and potentially splits a character in
the middle.  A subject line may end up showing like this:

     ".... fö?? bar".   (instead of  ".... föö bar".)

if split incorrectly.

RFC 2047, section 5 (3) explicitly forbids such beaviour

    Each 'encoded-word' MUST represent an integral number of
    characters.  A multi-octet character may not be split across
    adjacent 'encoded- word's.

that means that e.g. for

    Subject: .... föö bar

encoding

    Subject: =?UTF-8?q?....=20f=C3=B6=C3=B6?=
     =?UTF-8?q?=20bar?=

is correct, and

    Subject: =?UTF-8?q?....=20f=C3=B6=C3?=      <-- NOTE ö is broken here
     =?UTF-8?q?=B6=20bar?=

is not, because "ö" character UTF-8 encoding C3 B6 is split here across
adjacent encoded words.

To fix the problem, make the loop grab one _character_ at a time and
determine its output length to see where to break the output line.  Note
that this version only knows about UTF-8, but the logic to grab one
character is abstracted out in mbs_chrlen() function to make it possible
to extend it to other encodings with the help of iconv in the future.

45c45e300b git add: start preparing for "git add <pathspec>..." to default to "-A"
When "git add subdir/" is run without "-u" or "-A" option, e.g.

    $ edit subdir/x
    $ create subdir/y
    $ rm subdir/z
    $ git add subdir/

the command does not notice removal of paths (e.g. subdir/z) from
the working tree.  This sometimes confuses new people, as arguably
"git add" is told to record the current state of "subdir/" as a
whole, not the current state of the paths that exist in the working
tree that matches that pathspec (the latter by definition excludes
the state of "subdir/z" because it does not exist in the working
tree).

Plan to eventually make "git add" pretend as if "-A" is given when
there is a pathspec on the command line.  When resolving a conflict
to remove a path, the current code tells you to "git rm $path", but
with such a change, you will be able to say "git add $path" (of
course you can do "git add -A $path" today).  That means that we can
simplify the advice messages given by "git status".  That all will
be in Git 2.0 or later, if we are going to do so.

For that transition to work, people need to learn either to say "git
add --no-all subdir/" when they want to ignore the removed paths
like "subdir/z", or to say "git add -A subdir/" when they want to
take the state of the directory as a whole.

"git add" without any argument will continue to be a no-op.

2cd83d10bb setup: suppress implicit "." work-tree for bare repos
If an explicit GIT_DIR is given without a working tree, we
implicitly assume that the current working directory should
be used as the working tree. E.g.,:

  GIT_DIR=/some/repo.git git status

would compare against the cwd.

Unfortunately, we fool this rule for sub-invocations of git
by setting GIT_DIR internally ourselves. For example:

  git init foo
  cd foo/.git
  git status ;# fails, as we expect
  git config alias.st status
  git status ;# does not fail, but should

What happens is that we run setup_git_directory when doing
alias lookup (since we need to see the config), set GIT_DIR
as a result, and then leave GIT_WORK_TREE blank (because we
do not have one). Then when we actually run the status
command, we do setup_git_directory again, which sees our
explicit GIT_DIR and uses the cwd as an implicit worktree.

It's tempting to argue that we should be suppressing that
second invocation of setup_git_directory, as it could use
the values we already found in memory. However, the problem
still exists for sub-processes (e.g., if "git status" were
an external command).

You can see another example with the "--bare" option, which
sets GIT_DIR explicitly. For example:

  git init foo
  cd foo/.git
  git status ;# fails
  git --bare status ;# does NOT fail

We need some way of telling sub-processes "even though
GIT_DIR is set, do not use cwd as an implicit working tree".
We could do it by putting a special token into
GIT_WORK_TREE, but the obvious choice (an empty string) has
some portability problems.

Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE,
which suppresses the use of cwd as a working tree when
GIT_DIR is set. We trigger the new variable when we know we
are in a bare setting.

The variable is left intentionally undocumented, as this is
an internal detail (for now, anyway). If somebody comes up
with a good alternate use for it, and once we are confident
we have shaken any bugs out of it, we can consider promoting

This adds a test for the fix in bf1d68f (git-p4: use absolute
directory for PWD env var, 2011-12-09).  It is necessary to
set PWD to an absolute path so that p4 can find files referenced
by non-absolute paths, like the value of the P4CONFIG environment
variable.

P4 does not open files directly; it builds a path by prepending
the contents of the PWD environment variable.

For example, if you are using the "simple", "current", or "upstream"

cf41982806 submodule: add 'deinit' command
With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).

Help those users by providing a 'deinit' command. This removes the
whole submodule.<name> section from .git/config (either for the given
submodule(s) or for all those which have been initialized if '.' is used)
together with their work tree. Fail if the current work tree contains
modifications (unless forced), but don't complain when either the work
tree is already removed or no settings are found in .git/config.

Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand
to the completion list.

8b1bd02415 Make !pattern in .gitattributes non-fatal
Before 82dce99 (attr: more matching optimizations from .gitignore,
2012-10-15), .gitattributes did not have any special treatment of a
leading '!'.  The docs, however, always said

  The rules how the pattern matches paths are the same as in
  `.gitignore` files; see linkgit:gitignore[5].

By those rules, leading '!' means pattern negation.  So 82dce99
correctly determined that this kind of line makes no sense and should
be disallowed.

However, users who actually had a rule for files starting with a '!'
are in a bad position: before 82dce99 '!' matched that literal
character, so it is conceivable that users have .gitattributes with
such lines in them.  After 82dce99 the unescaped version was
disallowed in such a way that git outright refuses to run(!) most
commands in the presence of such a .gitattributes.  It therefore
becomes very hard to fix, let alone work with, such repositories.

Let's at least allow the users to fix their repos: change the fatal
error into a warning.

2092678cd5 name-hash.c: fix endless loop with core.ignorecase=true
With core.ignorecase=true, name-hash.c builds a case insensitive index of
all tracked directories. Currently, the existing cache entry structures are
added multiple times to the same hashtable (with different name lengths and
hash codes). However, there's only one dir_next pointer, which gets
completely messed up in case of hash collisions. In the worst case, this
causes an endless loop if ce == ce->dir_next (see t7062).

Use a separate hashtable and separate structures for the directory index
so that each directory entry has its own next pointer. Use reference
counting to track which directory entry contains files.

There are only slight changes to the name-hash.c API:
- new free_name_hash() used by read_cache.c::discard_index()
- remove_name_hash() takes an additional index_state parameter
- index_name_exists() for a directory (trailing '/') may return a cache
  entry that has been removed (CE_UNHASHED). This is not a problem as the
  return value is only used to check if the directory exists (dir.c) or to
  normalize casing of directory names (read-cache.c).

Getting rid of cache_entry.dir_next reduces memory consumption, especially
with core.ignorecase=false (which doesn't use that member at all).

With core.ignorecase=true, building the directory index is slightly faster
as we add / check the parent directory first (instead of going through all
directory levels for each file in the index). E.g. with WebKit (~200k
files, ~7k dirs), time spent in lazy_init_name_hash is reduced from 176ms
to 130ms.

d3c1472fe3 archive-zip: fix compressed size for stored export-subst files
Currently ZIP archive entries of files with export-subst attribute are
broken if they are stored uncompressed.

We get the size of a file from sha1_object_info(), but this number is
likely wrong for files whose contents are changed due to export-subst
placeholder expansion.  We use sha1_file_to_archive() to get the
expanded file contents and size in that case.  We proceed to use that
size for the uncompressed size field (good), but the compressed size
field is set based on the size from sha1_object_info() (bad).

This matters only for uncompressed files because for deflated files
we use the correct value after compression is done.  And for files
without export-subst expansion the sizes from sha1_object_info() and
sha1_file_to_archive() are the same, so they are unaffected as well.

This patch fixes the issue by setting the compressed size based on the
uncompressed size only after we actually know the latter.

Also make use of the test file substfile1 to check for the breakage;
it was only stored verbatim so far.  For that purpose, set the
attribute export-subst and replace its contents with the expected
expansion after committing.

7ec30aaa5b Provide a mechanism to turn off symlink resolution in ceiling paths
Commit 1b77d83cab 'setup_git_directory_gently_1(): resolve symlinks
in ceiling paths' changed the setup code to resolve symlinks in the
entries in GIT_CEILING_DIRECTORIES.  Because those entries are
compared textually to the symlink-resolved current directory, an
entry in GIT_CEILING_DIRECTORIES that contained a symlink would have
no effect.  It was known that this could cause performance problems
if the symlink resolution *itself* touched slow filesystems, but it
was thought that such use cases would be unlikely.  The intention of
the earlier change was to deal with a case when the user has this:

	GIT_CEILING_DIRECTORIES=/home/gitster

but in reality, /home/gitster is a symbolic link to somewhere else,
e.g. /net/machine/home4/gitster. A textual comparison between the
specified value /home/gitster and the location getcwd(3) returns
would not help us, but readlink("/home/gitster") would still be
fast.

After this change was released, Anders Kaseorg <andersk@mit.edu>
reported:

> [...] my computer has been acting so slow when I’m not connected to
> the network.  I put various network filesystem paths in
> $GIT_CEILING_DIRECTORIES, such as
> /afs/athena.mit.edu/user/a/n/andersk (to avoid hitting its parents
> /afs/athena.mit.edu, /afs/athena.mit.edu/user/a, and
> /afs/athena.mit.edu/user/a/n which all live in different AFS
> volumes).  Now when I’m not connected to the network, every
> invocation of Git, including the __git_ps1 in my shell prompt, waits
> for AFS to timeout.

To allow users to work around this problem, give them a mechanism to
turn off symlink resolution in GIT_CEILING_DIRECTORIES entries.  All
the entries that follow an empty entry will not be checked for symbolic
links and used literally in comparison.  E.g. with these:

	GIT_CEILING_DIRECTORIES=:/foo/bar:/xyzzy or
	GIT_CEILING_DIRECTORIES=/foo/bar::/xyzzy

we will not readlink("/xyzzy") because it comes after an empty entry.

With the former (but not with the latter), "/foo/bar" comes after an
empty entry, and we will not readlink it, either.

c19387e799 name-hash: allow hashing an empty string
Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"

Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.

Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

a24a41ea9a git-commit: only append a newline to -m mesg if necessary
Currently, git will append two newlines to every message supplied via
the -m switch.  The purpose of this is to allow -m to be supplied
multiple times and have each supplied string become a paragraph in the
resulting commit message.

Normally, this does not cause a problem since any trailing newlines will
be removed by the cleanup operation.  If cleanup=verbatim for example,
then the trailing newlines will not be removed and will survive into the
resulting commit message.

Instead, let's ensure that the string supplied to -m is newline terminated,
but only append a second newline when appending additional messages.

Fixes the test in t7502.

5b012c80a1 t7502: demonstrate breakage with a commit message with trailing newlines
This test attempts to verify that a commit message supplied to 'git
commit' via the -m switch was used in full as the commit message for a
commit when --cleanup=verbatim was used.

But, this test has been broken since it was introduced.  Since the
commit message containing trailing newlines was supplied to 'git commit'
using a command substitution, the trailing newlines were removed by the
shell.  This means that a string without any trailing newlines was
actually supplied to 'git commit'.

The test was able to complete successfully since internally, git appends
two newlines to each string supplied via the -m switch.  So, the two
newlines removed by the shell were then re-added by git, and the
resulting commit matched what was expected.

So, let's move the initial creation of the commit message string out
from within a previous test so that it stands alone.  Assign the desired
commit message to a variable using literal newlines.  Then populate the
expect file from the contents of the commit message variable.  This way
the shell variable becomes the authoritative source of the commit
message and can be supplied via the -m switch with the trailing newlines
intact.

Mark this test as failing, since it is not handled correctly by git.
As described above, git appends two extra newlines to every string
supplied via -m, even to the ones that already end with a newline.

67dabab058 t/t7502: compare entire commit message with what was expected
This test attempts to verify that a commit in "verbatim" mode, when
supplied a commit template, produces a commit in which the commit
message matches exactly the template that was supplied.  But, since the
commit operation appends additional instructions for the user as
comments in the commit buffer, which would cause the comparison to fail,
this test decided to compare only the first three lines (the length of
the template) of the resulting commit message to the original template
file.

This has two problems.

  1. It does not allow the template to be lengthened or shortened
     without also modifying the number of lines that are considered
     significant (i.e. the argument to 'head -n').
  2. It will not catch a bug in git that causes git to append additional
     lines to the commit message.

So, let's use the --no-status option to 'git commit' which will cause
git to refrain from appending the lines of instructional text to the
commit message.  This will allow the entire resulting commit message to
be compared against the expected value.

959a26231f Unify appending signoff in format-patch, commit and sequencer
There are two implementations of append_signoff in log-tree.c and
sequencer.c, which do more or less the same thing.  Unify on top of the
sequencer.c implementation.

Add a test in t4014 to demonstrate support for non-s-o-b elements in the
commit footer provided by sequence.c:append_sob.  Mark tests fixed as
appropriate.

       2. ensure various s-o-b -like elements in the footer are handled as

04deccda11 log: re-encode commit messages before grepping
If you run "git log --grep=foo", we will run your regex on
the literal bytes of the commit message. This can provide
confusing results if the commit message is not in the same
encoding as your grep expression (or worse, you have commits
in multiple encodings, in which case your regex would need
to be written to match either encoding). On top of this, we
might also be grepping in the commit's notes, which are
already re-encoded, potentially leading to grepping in a
buffer with mixed encodings concatenated. This is insanity,
but most people never noticed, because their terminal and
their commit encodings all match.

Instead, let's massage the to-be-grepped commit into a
standardized encoding. There is not much point in adding a
flag for "this is the encoding I expect my grep pattern to
match"; the only sane choice is for it to use the log output
encoding. That is presumably what the user's terminal is
using, and it means that the patterns found by the grep will
match the output produced by git.

As a bonus, this fixes a potential segfault in commit_match
when commit->buffer is NULL, as we now build on logmsg_reencode,
which handles reading the commit buffer from disk if
necessary. The segfault can be triggered with:

        git commit -m 'text1' --allow-empty
        git commit -m 'text2' --allow-empty
        git log --graph --no-walk --grep 'text2'

which arguably does not make any sense (--graph inherently
wants a connected history, and by --no-walk the command line
is telling us to show discrete points in history without
connectivity), and we probably should forbid the
combination, but that is a separate issue.

daebaa7813 upload/receive-pack: allow hiding ref hierarchies
A repository may have refs that are only used for its internal
bookkeeping purposes that should not be exposed to the others that
come over the network.

Teach upload-pack to omit some refs from its initial advertisement
by paying attention to the uploadpack.hiderefs multi-valued
configuration variable.  Do the same to receive-pack via the
receive.hiderefs variable.  As a convenient short-hand, allow using
transfer.hiderefs to set the value to both of these variables.

Any ref that is under the hierarchies listed on the value of these
variable is excluded from responses to requests made by "ls-remote",
"fetch", etc. (for upload-pack) and "push" (for receive-pack).

Because these hidden refs do not count as OUR_REF, an attempt to
fetch objects at the tip of them will be rejected, and because these
refs do not get advertised, "git push :" will not see local branches
that have the same name as them as "matching" ones to be sent.

An attempt to update/delete these hidden refs with an explicit
refspec, e.g. "git push origin :refs/hidden/22", is rejected.  This
is not a new restriction.  To the pusher, it would appear that there
is no such ref, so its push request will conclude with "Now that I
sent you all the data, it is time for you to update the refs.  I saw
that the ref did not exist when I started pushing, and I want the
result to point at this commit".  The receiving end will apply the
compare-and-swap rule to this request and rejects the push with
"Well, your update request conflicts with somebody else; I see there
is such a ref.", which is the right thing to do. Otherwise a push to
a hidden ref will always be "the last one wins", which is not a good
default.

0722c805d6 status: show the branch name if possible in in-progress info
The typical use-case is starting a rebase, do something else, come
back the day after, run "git status" or make a new commit and wonder
what in the world's going on. Which branch is being rebased is
probably the most useful tidbit to help, but the target may help
too.

Ideally, I would have loved to see "rebasing master on

so this patch writes "rebasing master on a78c8c98b" as a
half-measure to remind future users of that potential improvement.

Earlier, a230949 (am --rebasing: get patch body from commit, not

commit object while rebasing, instead of reading from the rebase-am
front-end.  While doing so, it used "git diff-tree" but without
giving it the "--full-index" option.

This does not matter for in-repository objects; during rebasing, any
abbreviated object name should uniquely identify them.

But we may be rebasing a commit that contains a change to a gitlink,
in which case we usually should not have the object (it names a
commit in the submodule).  A full object name is necessary to later
reconstruct a fake ancestor index for them.

d040350813 branch: let branch filters imply --list
Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:

  git branch --contains=foo bar

will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:

  1. Flag an error; the arguments do not make sense.

  2. Implicitly go into `--list` mode

This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.

That leaves the case where an explicit modification option
like `-d` is given.  We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

4cea4d6608 git p4 test: use test_chmod for cygwin
This test does a commit that is a pure mode change, submits
it to p4 but causes the submit to fail.  It verifies that
the state in p4 as well as the client directory are both
unmodified after the failed submit.

On cygwin, "chmod +x" does nothing, so use the test_chmod
function to modify the index directly too.

Also on cygwin, the executable bit cannot be seen in the
filesystem, so avoid that part of the test.  The checks of
p4 state are still valid, though.

e9df0f9c7a git p4: cygwin p4 client does not mark read-only
There are some old versions of p4, compiled for cygwin, that
treat read-only files differently.

Normally, a file that is not open is read-only, meaning that
"test -w" on the file is false.  This works on unix, and it works
on windows using the NT version of p4.  The cygwin version
of p4, though, changes the permissions, but does not set the
windows read-only attribute, so "test -w" returns false.

Notice this oddity and make the tests work, even on cygiwn.

cfa96496bd git p4 test: translate windows paths for cygwin
Native windows binaries do not understand posix-like
path mapping offered by cygwin.  Convert paths to native
using "cygpath --windows" before presenting them to p4d.

This is done using the AltRoots mechanism of p4.  Both the
posix and windows forms are put in the client specification,
allowing p4 to find its location by native path even though
the environment reports a different PWD.

Shell operations in tests will use the normal form of $cli,
which will look like a posix path in cygwin, while p4 will
use AltRoots to match against the windows form of the working
directory.

This mechanism also handles the symlink issue that was fixed in
23bd0c9 (git p4 test: use real_path to resolve p4 client
symlinks, 2012-06-27).  Now that every p4 client view has
an AltRoots with the real_path in it, explicitly calculating
the real_path elsewhere is not necessary.

This requires a fix to one of the client_view callers.

be5c9fb904 logmsg_reencode: lazily load missing commit buffers
Usually a commit that makes it to logmsg_reencode will have
been parsed, and the commit->buffer struct member will be
valid. However, some code paths will free commit buffers
after having used them (for example, the log traversal
machinery will do so to keep memory usage down).

Most of the time this is fine; log should only show a commit
once, and then exits. However, there are some code paths
where this does not work. At least two are known:

  1. A commit may be shown as part of a regular ref, and
     then it may be shown again as part of a submodule diff
     (e.g., if a repo contains refs to both the superproject
     and subproject).

  2. A notes-cache commit may be shown during "log --all",
     and then later used to access a textconv cache during a
     diff.

Lazily loading in logmsg_reencode does not necessarily catch
all such cases, but it should catch most of them. Users of
the commit buffer tend to be either parsing for structure
(in which they will call parse_commit, and either we will
already have parsed, or we will load commit->buffer lazily
there), or outputting (either to the user, or fetching a
part of the commit message via format_commit_message). In
the latter case, we should always be using logmsg_reencode
anyway (and typically we do so via the pretty-print
machinery).

If there are any cases that this misses, we can fix them up
to use logmsg_reencode (or handle them on a case-by-case
basis if that is inappropriate).

5047822347 t9902: protect test from stray build artifacts
When you have random build artifacts in your build directory, left
behind by running "make" while on another branch, the "git help -a"
command run by __git_list_all_commands in the completion script that
is being tested does not have a way to know that they are not part
of the subcommands this build will ship.  Such extra subcommands may
come from the user's $PATH.  They will interfere with the tests that
expect a certain prefix to uniquely expand to a known completion.

Instrument the completion script and give it a way for us to tell
what (subset of) subcommands we are going to ship.

Also add a test to "git --help <prefix><TAB>" expansion.  It needs
to show not just commands but some selected documentation pages.

Based on an idea by Jeff King.

This is fewer lines of code, but more importantly, fixes a

9, not 3. This is a holdover from an earlier iteration of

As a result, we could erroneously reject some filters with

4db86e8b6e Update :/abc ambiguity check
:/abc may mean two things:

- as a revision, it means the revision that has "abc" in commit
  message.

- as a pathpec, it means "abc" from root.

Currently we see ":/abc" as a rev (most of the time), but never see it
as a pathspec even if "abc" exists and "git log :/abc" will gladly
take ":/abc" as rev even it's ambiguous. This patch makes it:

- ambiguous when "abc" exists on worktree
- a rev if abc does not exist on worktree
- a path if abc is not found in any commits (although better use
  "--" to avoid ambiguation because searching through commit DAG is
  expensive)

A plus from this patch is, because ":/" never matches anything as a
rev, it is never considered a valid rev and because root directory
always exists, ":/" is always unambiguously seen as a pathspec.

Add support for a pre-push hook which can be used to determine if the
set of refs to be pushed is suitable for the target repository.  The
hook is run with two arguments specifying the name and location of the
destination repository.

Information about what is to be pushed is provided by sending lines of
the following form to the hook's standard input:

  <local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF

If the hook exits with a non-zero status, the push will be aborted.

This will allow the script to determine if the push is acceptable based
on the target repository and branch(es), the commits which are to be
pushed, and even the source branches in some cases.

4b7f53da76 simplify-merges: drop merge from irrelevant side branch
The merge simplification rule stated in 6546b59 (revision traversal:
show full history with merge simplification, 2008-07-31) still
treated merge commits too specially.  Namely, in a history with this
shape:

	---o---o---M
	          /
         x---x---x

where three 'x' were on a history completely unrelated to the main
history 'o' and do not touch any of the paths we are following, we
still said that after simplifying all of the parents of M, 'x'
(which is the leftmost 'x' that rightmost 'x simplifies down to) and
'o' (which would be the last commit on the main history that touches
the paths we are following) are independent from each other, and
both need to be kept.

That is incorrect; when the side branch 'x' never touches the paths,
it should be removed to allow M to simplify down to the last commit
on the main history that touches the paths.

256b9d70a4 push: fix "refs/tags/ hierarchy cannot be updated without --force"
When pushing to update a branch with a commit that is not a
descendant of the commit at the tip, a wrong message "already
exists" was given, instead of the correct "non-fast-forward", if we
do not have the object sitting in the destination repository at the
tip of the ref we are updating.

The primary cause of the bug is that the check in a new helper
function is_forwardable() assumed both old and new objects are
available and can be checked, which is not always the case.

The way the caller uses the result of this function is also wrong.
If the helper says "we do not want to let this push go through", the
caller unconditionally translates it into "we blocked it because the
destination already exists", which is not true at all in this case.

Fix this by doing these three things:

 * Remove unnecessary not_forwardable from "struct ref"; it is only
   used inside set_ref_status_for_push();

 * Make "refs/tags/" the only hierarchy that cannot be replaced
   without --force;

 * Remove the misguided attempt to force that everything that
   updates an existing ref has to be a commit outside "refs/tags/"
   hierarchy.

The policy last one tried to implement may later be resurrected and
extended to ensure fast-forwardness (defined as "not losing
objects", extending from the traditional "not losing commits from
the resulting history") when objects that are not commit are
involved (e.g. an annotated tag in hierarchies outside refs/tags),
but such a logic belongs to "is this a fast-forward?" check that is
done by ref_newer(); is_forwardable(), which is now removed, was not
the right place to do so.

eff80a9fd9 Allow custom "comment char"
Some users do want to write a line that begin with a pound sign, #,
in their commit log message.  Many tracking system recognise
a token of #<bugid> form, for example.

The support we offer these use cases is not very friendly to the end
users.  They have a choice between

 - Don't do it.  Avoid such a line by rewrapping or indenting; and

 - Use --cleanup=whitespace but remove all the hint lines we add.

Give them a way to set a custom comment char, e.g.

    $ git -c core.commentchar="%" commit

so that they do not have to do either of the two workarounds.

40d69ac3a4 git p4: allow short ref names to --branch
For a clone or sync, --branch says where the newly imported
branch should go, or which existing branch to sync up.  It
takes an argument, which is currently either something that
starts with "refs/", or if not, "refs/heads/p4" is prepended.

Putting it in heads seems like a bad default; these should
go in remotes/p4/ in most situations.  Make that the new default,
and be more liberal in the form of the branch name.

Add failing tests to document behavior when there are multiple p4
branches, as created using the --branch option.  In particular:

Using clone --branch populates the specified branch correctly, but
dies with an error when trying to checkout master.

Calling sync without a master branch dies with an error looking for
master.  When there are two or more branches, a sync does
nothing due to branch detection code, but that is expected.

Using sync --branch to try to update just a particular branch
updates no branch, but appears to succeed.

166ec2e96e reset: allow reset on unborn branch
Some users seem to think, knowingly or not, that being on an unborn
branch is like having a commit with an empty tree checked out, but
when run on an unborn branch, "git reset" currently fails with:

  fatal: Failed to resolve 'HEAD' as a valid ref.

Instead of making users figure out that they should run

 git rm --cached -r .

, let's teach "git reset" without a revision argument, when on an
unborn branch, to behave as if the user asked to reset to an empty
tree. Don't take the analogy with an empty commit too far, though, but
still disallow explictly referring to HEAD in "git reset HEAD".

Resetting with paths does not update HEAD and there is nothing else
that a commit should be needed for. Relax the argument parsing so only
a tree is required.

The sha1 is only passed to read_from_tree(), which already only
requires a tree.

The "rev" variable we pass to run_add_interactive() will resolve to a
tree. This is fine since interactive_reset only needs the parameter to
be a treeish and doesn't use it for display purposes.

worktree is dirty after resetting, which is inconsistent with reset
without pathspec, and it makes it harder to know whether the command
really failed. Change it to exit with code 0 regardless of whether the
worktree is dirty so that non-zero indicates an error.

This makes the 4 "disambiguation" test cases in t7102 clearer since
they all used to "fail", 3 of which "failed" due to changes in the

get_shallow_commits() is used to determine the cut points at a given
depth (i.e. the number of commits in a chain that the user likes to

upload-pack always return one commit more than requested. This patch

4dcb167fc3 fetch: add --unshallow for turning shallow repo into complete one
The user can do --depth=2147483647 (*) for restoring complete repo
now. But it's hard to remember. Any other numbers larger than the
longest commit chain in the repository would also do, but some
guessing may be involved. Make easy-to-remember --unshallow an alias
for --depth=2147483647.

Make upload-pack recognize this special number as infinite depth. The
effect is essentially the same as before, except that upload-pack is
more efficient because it does not have to traverse to the bottom
anymore.

The chance of a user actually wanting exactly 2147483647 commits
depth, not infinite, on a repository with a history that long, is
probably too small to consider. The client can learn to add or
subtract one commit to avoid the special treatment when that actually
happens.

(*) This is the largest positive number a 32-bit signed integer can
    contain. JGit and older C Git store depth as "int" so both are OK
    with this number. Dulwich does not support shallow clone.

283b365e45 t1402: work around shell quoting issue on NetBSD
The test fails for me on NetBSD 6.0.1 and reports:

	ok 1 - ref name '' is invalid
	ok 2 - ref name '/' is invalid
	ok 3 - ref name '/' is invalid with options --allow-onelevel
	ok 4 - ref name '/' is invalid with options --normalize
	error: bug in the test script: not 2 or 3 parameters to test-expect-success

The alleged bug is in this line:

	invalid_ref NOT_MINGW '/' '--allow-onelevel --normalize'

invalid_ref() constructs a test case description using its last argument,
but the shell seems to split it up into two pieces if it contains a
space.  Minimal test case:

	# on NetBSD with /bin/sh
	$ a() { echo $#-$1-$2; }
	$ t="x"; a "${t:+$t}"
	1-x-
	$ t="x y"; a "${t:+$t}"
	2-x-y
	$ t="x y"; a "${t:+x y}"
	1-x y-

	# and with bash
	$ t="x y"; a "${t:+$t}"
	1-x y-
	$ t="x y"; a "${t:+x y}"
	1-x y-

This may be a bug in the shell, but here's a simple workaround: Construct
the description string first and store it in a variable, and then use
that to call test_expect_success().

55292ea25d t5003: check if unzip supports symlinks
Only add a symlink to the repository if both the filesystem and
unzip support symlinks.  To check the latter, add a ZIP file
containing a symlink, created like this with InfoZIP zip 3.0:

	$ echo sample text >textfile
	$ ln -s textfile symlink
	$ zip -y infozip-symlinks.zip textfile symlink

If we can extract it successfully, we add a symlink to the test
repository for git archive --format=zip, or otherwise skip that
step.  Users can see the skipped test and perhaps run it again
with a different unzip version.

25d3d32363 t0024, t5000: use test_lazy_prereq for UNZIP
This change makes the code smaller and we can put it at the top of
the script, its rightful place as setup code.
