I want directories of my working tree to be linked to from various
paths on my filesystem where third-party components expect them, both
in development and production environments. A build system's install
step could solve this, but I develop scripts and web pages that don't
need to be built. Git's submodule system could solve this, but we
tend to develop, branch, and test those directories all in unison, so
one big repository feels more natural. We prefer to edit and commit
on the symlinked paths, not the canonical ones, and in that setting,
"git pull" fails to find the top-level directory of the repository
while other commands work fine.
"git pull" fails because POSIX shells have a notion of current working
directory that is different from getcwd(). The shell stores this path
in PWD. As a result, "cd ../" can be interpreted differently in a
shell script than chdir("../") in a C program. The shell interprets
"../" by essentially stripping the last textual path component from
PWD, whereas C chdir() follows the ".." link in the current directory
on the filesystem. When PWD is a symlink, these are different
destinations. As a result, Git's C commands find the correct
top-level working tree, and shell scripts do not.
Changes:
* When interpreting a relative upward (../) path in cd_to_toplevel,
prepend the cwd without symlinks, given by /bin/pwd
* Add tests for cd_to_toplevel and "git pull" in a symlinked
directory that failed before this fix, plus contrasting scenarios
that already worked

Currently we just skip rewrite diffs for binary files; this

Conceptually, rewrite diffs should be in the exact same
format as the a non-rewrite diff, except that we refuse to
share any context. Thus it makes very little sense for "git
diff" to show a textconv'd diff, but for "git diff -B" to
show "Binary files differ".

The current emit_rewrite_diff code always writes a text patch without
checking whether the content is binary. This means that if you end up with
a rewrite diff for a binary file, you get lots of raw binary goo in your
patch.
Instead, if we have binary files, then let's just skip emit_rewrite_diff
altogether. We will already have shown the "dissimilarity index" line, so
it is really about the diff contents. If binary diffs are turned off, the
"Binary files a/file and b/file differ" message should be the same in
either case. If we do have binary patches turned on, there isn't much
point in making a less-efficient binary patch that does a total rewrite;
no human is going to read it, and since binary patches don't apply with
any fuzz anyway, the result of application should be the same.

find_parent_branch generates branch@rev type branches when one has to
look back through SVN history to properly get the history for a branch
copied from somewhere not already being tracked by git-svn. If in the
process of fetching this history, git-svn is interrupted, then when one
fetches again, it will use whatever was last fetched as the parent
commit and fail to fetch any more history which it didn't get to before
being terminated. This is especially troubling in that different
git-svn copies of the same SVN repository can end up with different
commit sha1s, incorrectly showing the history as divergent and
precluding easy collaboration using git push and fetch.
To fix this, when we initialise the Git::SVN object $gs to search for
and perhaps fetch history, we check if there are any commits in SVN in
the range between the current revision $gs is at, and the top revision
for which we were asked to fill history. If there are commits we're
missing in that range, we continue the fetch from the current revision
to the top, properly getting all history before using it as the parent
for the branch we're trying to create.

checkout: Don't crash when switching away from an invalid branch.
Pushing into the currently checked out branch of a non-bare
repository can be dangerous; the HEAD then loses sync with
the index and working tree, and it looks in the receiving
repo as if the pushed changes have been reverted in the
index (since they were never there in the first place).
This patch adds a safety valve that checks for this
condition and either generates a warning or denies the
update. We trigger the check only on a non-bare repository,
since a bare repo does not have a working tree (and in fact,
pushing to the HEAD branch is a common workflow for
publishing repositories).
The behavior is configurable via receive.denyCurrentBranch,
defaulting to "warn" so as not to break existing setups
(though it may, after a deprecation period, switch to
"refuse" by default). For users who know what they are doing
and want to silence the warning (e.g., because they have a
post-receive hook that reconciles the HEAD and working
tree), they can turn off the warning by setting it to false
or "ignore".

SVN itself always stores log messages in the repository as
UTF-8. git always stores/retrieves everything as raw binary
data with no transformations whatsoever.
To interact with SVN, we need to encode log messages as UTF-8
before sending them to SVN, as SVN cannot do it for us. When
retrieving log messages from SVN, we also need to (attempt to)
reencode the UTF-8 log message back to the user-specified commit
encoding.
Note, handling i18n.logoutputencoding for "git svn log" also
needs to be done in a future change.
Also, this change only deals with the encoding of commit
messages and nothing else (path names, blob content, ...).

Abstract
--------
With index v2 we have a per object CRC to allow quick and safe reuse of
pack data when repacking. This, however, doesn't currently prevent a
stealth corruption from being propagated into a new pack when _not_
reusing pack data as demonstrated by the modification to t5302 included
here.
The Context
-----------
The Git database is all checksummed with SHA1 hashes. Any kind of
corruption can be confirmed by verifying this per object hash against
corresponding data. However this can be costly to perform systematically
and therefore this check is often not performed at run time when
accessing the object database.
First, the loose object format is entirely compressed with zlib which
already provide a CRC verification of its own when inflating data. Any
disk corruption would be caught already in this case.
Then, packed objects are also compressed with zlib but only for their
actual payload. The object headers and delta base references are not
deflated for obvious performance reasons, however this leave them
vulnerable to potentially undetected disk corruptions. Object types
are often validated against the expected type when they're requested,
and deflated size must always match the size recorded in the object header,
so those cases are pretty much covered as well.
Where corruptions could go unnoticed is in the delta base reference.
Of course, in the OBJ_REF_DELTA case, the odds for a SHA1 reference to
get corrupted so it actually matches the SHA1 of another object with the
same size (the delta header stores the expected size of the base object
to apply against) are virtually zero. In the OBJ_OFS_DELTA case, the
reference is a pack offset which would have to match the start boundary
of a different base object but still with the same size, and although this
is relatively much more "probable" than in the OBJ_REF_DELTA case, the
probability is also about zero in absolute terms. Still, the possibility
exists as demonstrated in t5302 and is certainly greater than a SHA1
collision, especially in the OBJ_OFS_DELTA case which is now the default
when repacking.
Again, repacking by reusing existing pack data is OK since the per object
CRC provided by index v2 guards against any such corruptions. What t5302
failed to test is a full repack in such case.
The Solution
------------
As unlikely as this kind of stealth corruption can be in practice, it
certainly isn't acceptable to propagate it into a freshly created pack.
But, because this is so unlikely, we don't want to pay the run time cost
associated with extra validation checks all the time either. Furthermore,
consequences of such corruption in anything but repacking should be rather
visible, and even if it could be quite unpleasant, it still has far less
severe consequences than actively creating bad packs.
So the best compromize is to check packed object CRC when unpacking
objects, and only during the compression/writing phase of a repack, and
only when not streaming the result. The cost of this is minimal (less
than 1% CPU time), and visible only with a full repack.
Someone with a stats background could provide an objective evaluation of
this, but I suspect that it's bad RAM that has more potential for data
corruptions at this point, even in those cases where this extra check
is not performed. Still, it is best to prevent a known hole for
corruption when recreating object data into a new pack.
What about the streamed pack case? Well, any client receiving a pack
must always consider that pack as untrusty and perform full validation
anyway, hence no such stealth corruption could be propagated to remote
repositoryes already. It is therefore worthless doing local validation
in that case.

These tests provide a basic sanity check that textconv'd

_should_ work; thus some of the tests are marked to expect
failure.
In particular, we fail to actually textconv anything because
the 'diff.foo.binary' config option is not set, which will
be fixed in the next patch.
This also means that some "expect_failure" tests actually

We treat symlinks as text containing the results of the

Similarly gitlink components just end up as the text
"Subproject commit $sha1", which we should leave intact.
Note that a typechange may be broken into two parts: the
removal of the old part and the addition of the new. In that
case, we _do_ show the textconv for any part which is the
addition or removal of a file we would ordinarily textconv,
since it is purely acting on the file contents.

Diffs that have been produced with textconv almost certainly
cannot be applied, so we want to be careful not to generate
them in things like format-patch.
This introduces a new diff options, ALLOW_TEXTCONV, which
controls this behavior. It is off by default, but is
explicitly turned on for the "log" family of commands, as
well as the "diff" porcelain (but not diff-* plumbing).
Because both text conversion and external diffing are
controlled by these diff options, we can get rid of the
"plumbing versus porcelain" distinction when reading the
config. This was an attempt to control the same thing, but
suffered from being too coarse-grained.

The original implementation of textconv put the conversion
into fill_mmfile. This was a bad idea for a number of
reasons:
- it made the semantics of fill_mmfile unclear. In some
cases, it was allocating data (if a text conversion
occurred), and in some cases not (if we could use the
data directly from the filespec). But the caller had
no idea which had happened, and so didn't know whether
the memory should be freed
- similarly, the caller had no idea if a text conversion
had occurred, and so didn't know whether the contents
should be treated as binary or not. This meant that we
incorrectly guessed that text-converted content was
binary and didn't actually show it (unless the user
overrode us with "diff.foo.binary = false", which then
created problems in plumbing where the text conversion
did _not_ occur)
- not all callers of fill_mmfile want the text contents. In
particular, we don't really want diffstat, whitespace
checks, patch id generation, etc, to look at the
converted contents.
This patch pulls the conversion code directly into
builtin_diff, so that we only see the conversion when
generating an actual patch. We also then know whether we are
doing a conversion, so we can check the binary-ness and free
the data from the mmfile appropriately (the previous version
leaked quite badly when text conversion was used)

If a file is different between the working tree copy, the index, and the
HEAD, then we do not allow it to be deleted without --force.
However, this is overly tight in the face of "git add --intent-to-add":
$ git add --intent-to-add file
$ : oops, I don't actually want to stage that yet
$ git rm --cached file
error: 'empty' has staged content different from both the
file and the HEAD (use -f to force removal)
$ git rm -f --cached file
Unfortunately, there is currently no way to distinguish between an empty
file that has been added and an "intent to add" file. The ideal behavior
would be to disallow the former while allowing the latter.
This patch loosens the safety valve to allow the deletion only if we are
deleting the cached entry and the cached content is empty. This covers
the intent-to-add situation, and assumes there is little harm in not
protecting users who have legitimately added an empty file. In many
cases, the file will still be empty, in which case the safety valve does
not trigger anyway (since the content remains untouched in the working
tree). Otherwise, we do remove the fact that no content was staged, but
given that the content is by definition empty, it is not terribly
difficult for a user to recreate it.
However, we still document the desired behavior in the form of two
tests. One checks the correct removal of an intent-to-add file. The other
checks that we still disallow removal of empty files, but is marked as
expect_failure to indicate this compromise. If the intent-to-add feature
is ever extended to differentiate between normal empty files and
intent-to-add files, then the safety valve can be re-tightened.

Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.
This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.
Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.
If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

When the "git status" display code was originally converted

Much later, 5698454e updated the code in ls-files to handle
some new cases caused by gitlinks. This left the code in
wt-status.c broken: it would display submodule directories
as untracked directories. Nobody noticed until now, however,
because unless status.showUntrackedFiles was set to "all",
submodule directories were not actually reported by
read_directory. So the bug was only triggered in the
presence of a submodule _and_ this config option.

Thus far git has not been removing the trailing newline from strings matched

While it might make sense to store what you want to pull, it typically is
plain wrong when the current branch is "master". This should only be
allowed when (an incorrect) "git pull origin master:master" tries to work
around by giving --update-head-ok to underlying "git fetch", and otherwise
we should refuse it, but somewhere along the lines we lost that behavior.

arguments, resulting in confusing diffs. A comment /* Again, the revs are all
reverse */ suggested there was a reason for this, but I can't figure out the
reason, so I removed the reversal of the arguments. Test case included.

Since dbf5e1e9, the '--no-validate' option is a Getopt::Long boolean
option. The '--no-' prefix (as in --no-validate) for boolean options
is not supported in Getopt::Long version 2.32 which was released with
Perl 5.8.0. This version only supports '--no' as in '--novalidate'.
More recent versions of Getopt::Long, such as version 2.34, support
either prefix. So use the older form in the tests.

We carefully verify that the input to git-apply is sane,
including cross-checking that the filenames we see in "+++"
headers match what was provided on the command line of "diff
--git". When --directory is used, however, we ended up
comparing the unadorned name to one with the prepended root,
causing us to complain about a mismatch.
We simply need to prepend the root directory, if any, when
pulling the name out of the git header.

In case there is no commit to apply (for example because you rebase to
upstream and all your local patches have been applied there), do not
fail. The non-interactive rebase already behaves that way.
Do this by introducing a new command, "noop", which is substituted for
an empty commit list, so that deleting the commit list can still abort
as before.

git init: --bare/--shared overrides system/global config
git-push.txt: Describe --repo option in more detail
git rm: refresh index before up-to-date check
Fix a few typos in relnotes
If core.bare or core.sharedRepository are set in /etc/gitconfig or
~/.gitconfig, then 'git init' will read the values when constructing a
new config file; reading them, however, will override the values
specified on the command line. In the case of --bare, this ends up
causing a segfault, without the repository being properly initialised;
in the case of --shared, the permissions are set according to the
existing config settings, not what was specified on the command line.
This fix saves any specified values for --bare and --shared prior to
reading existing config settings, and restores them after reading but
before writing the new config file. core.bare is ignored in all
situations, while core.sharedRepository will only be used if --shared
is not specified to git init.
Also includes testcases which use a specified global config file
override, demonstrating the former failure scenario.

It is sometimes desirable to disable the safety net of pre-rebase hook
when the user knows what he is doing (for example, when the original
changes on the branch have not been shown to the public yet).
This teaches --no-verify option to git-rebase, which is similar to the way
pre-commit hook is bypassed by git-commit.

When "git diff --no-index" is given an absolute pathname, it
would generate a diff header with the absolute path
prepended by the prefix, like:
diff --git a/dev/null b/foo
Not only is this nonsensical, and not only does it violate
the description of diffs given in git-diff(1), but it would
produce broken binary diffs. Unlike text diffs, the binary
diffs don't contain the filenames anywhere else, and so "git
apply" relies on this header to figure out the filename.
This patch just refuses to use an invalid name for anything
visible in the diff.
Now, this fixes the "git diff --no-index --binary a
/dev/null" kind of case (and we'll end up using "a" as the
basename), but some other insane cases are impossible to
handle. If you do
git diff --no-index --binary a /bin/echo
you'll still get a patch like
diff --git a/a b/bin/echo
old mode 100644
new mode 100755
index ...
and "git apply" will refuse to apply it for a couple of
reasons, and the diff is simply bogus.
And that, btw, is no longer a bug, I think. It's impossible
to know whethe the user meant for the patch to be a rename
or not. And as such, refusing to apply it because you don't
know what name you should use is probably _exactly_ the
right thing to do!

Since commit 6bb6b034 (builtin-commit: use commit_tree(), 2008-09-10),
builtin-commit performs a reduce_heads() unconditionally. However,
it's not always needed, and in some cases even harmful.
reduce_heads() is not needed for the initial commit or for an
"ordinary" commit, because they don't have any or have only one
parent, respectively.
reduce_heads() must be avoided when 'git commit' is run after a 'git
merge --no-ff --no-commit', otherwise it will turn the
non-fast-forward merge into fast-forward. For the same reason,
reduce_heads() must be avoided when amending such a merge commit.
To resolve this issue, 'git merge' will write info about whether
fast-forward is allowed or not to $GIT_DIR/MERGE_MODE. Based on this
info, 'git commit' will only perform reduce_heads() when it's
committing a merge and fast-forward is enabled.
Also add test cases to ensure that non-fast-forward merges are
committed and amended properly.

As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.
This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.
The test-case included in this patch was originally written
by Stephen Habermann <stephen@exigencecorp.com>, but has
been extensively modified since its creation.

We try to avoid using the "-q" or "-e" options, as they are
largely useless, as explained in aadbe44f.
There is one exception for "-e" here, which is in t7701 used
to produce an "or" of patterns. This can be rewritten as an
egrep pattern.
This patch also removes use of "grep -F" in favor of the
more widely available "fgrep".
