The original intention of 72909be (Add diff-option --ext-diff, 2007-06-30)
was to optionally allow the use of external diff viewer in "git log"

external diff" bit to the UI, but forgot to adjust the "git diff" codepath
that was set up to always allow use of the external diff viewer.

We can avoid doing this stripping altogether if the user didn't use "-v"

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.

Note that a typechange may be broken into two parts: the

Diffs that have been produced with textconv almost certainly
cannot be applied, so we want to be careful not to generate

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

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.

06cbe855 (Make core.sharedRepository more generic, 2008-04-16) made
several testcases in t1301-shared-repo.sh which fail if on a system
which creates files with extended attributes (e.g. SELinux), since ls
appends a '+' sign to the permission set in such cases. In fact,
POSIX.1 allows ls to add a single printable character after the usual
3x3 permission bits to show that an optional alternate/additional access
method is associated with the path.
This fixes the testcase to strip any such sign prior to verifying the
permission set.

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.
In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.
Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. Users that want to
change the default behavior can use the format.numbering config key.

When the "git status" display code was originally converted
to C, we copied the code from ls-files to discover whether a
pathname returned by read_directory was an "other", or
untracked, file.
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.
This patch pulls the ls-files code into a new function,
cache_name_is_other, and uses it in both places. This should
leave the ls-files functionality the same and fix the bug
in status.

`rebase -i -p` got its rev-list of commits to keep by --left-right and

already in the rebase target.
The dropped commits were then forgotten about when it came to rewriting the
parents of their descendents, so the descendents would get cherry-picked with
their old, unwritten parents and essentially make the rebase a no-op.

POSIX doth sayeth:
"In the regular expression processing described in IEEE Std 1003.1-2001,
the <newline> is regarded as an ordinary character and both a period and
a non-matching list can match one. ... Those utilities (like grep) that
do not allow <newline>s to match are responsible for eliminating any
<newline> from strings before matching against the RE."
Thus far git has not been removing the trailing newline from strings matched
against regular expression patterns. This has the effect that (quoting
Jonathan del Strother) "... a line containing just 'FUNCNAME' (terminated by
a newline) will be matched by the pattern '^(FUNCNAME.$)' but not
'^(FUNCNAME$)'", and more simply not '^FUNCNAME$'.

The problem with this is that 'git diff' always returns non-zero if it

Some confusing tutorials suggested that it would be a good idea to fetch
into the current branch with something like this:
git fetch origin master:master
(or even worse: the same command line with "pull" instead of "fetch").
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.
The check for the current branch is now _only_ performed in non-bare
repositories, which is an improvement from the original behaviour.
Some newer tests were depending on the broken behaviour of "git fetch"
this patch fixes, and have been adjusted.

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.

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 ':'

The effect is that the interactive rebase helper is used but

Suppose you're using git-svn to work with a certain SVN repository.
Since you don't like 'git-svn fetch' to take forever, and you don't want
to accidentally interrupt it and end up corrupting your repository, you
set up a remote Git repository to mirror the SVN repository, which does
its own 'git-svn fetch' on a cronjob; now you can 'git-fetch' from the
Git mirror into your local repository, and still dcommit to SVN when you
have changes to push.
After you do this, though, git-svn will get very confused if you ever
try to do 'git-svn fetch' in your local repository again, since its
rev_map will differ from the branch's head, and it will be unable to
fetch new commits from SVN because of the metadata conflict. But all
the necessary metadata are there in the Git commit message; git-svn
already knows how to rebuild rev_map files that get blown away, by
using the metadata.
This patch teaches git-svn do a partial rebuild of the rev_map to
match the true state of the branch, if it ever is used to fetch again.
This will only work for projects not using either noMetadata or
useSvmProps configuration options; if you are using these options,
git-svn will fall back to the previous behaviour.

Currently, the hunk headers produced by 'diff -p' are customizable by
setting the diff.*.funcname option in the config file. The 'funcname' option
takes a basic regular expression. This functionality was designed using the
GNU regex library which, by default, allows using backslashed versions of
some extended regular expression operators, even in Basic Regular Expression
mode. For example, the following characters, when backslashed, are
interpreted according to the extended regular expression rules: ?, +, and |.
As such, the builtin funcname patterns were created using some extended
regular expression operators.
Other platforms which adhere more strictly to the POSIX spec do not
interpret the backslashed extended RE operators in Basic Regular Expression
mode. This causes the pattern matching for the builtin funcname patterns to
fail on those platforms.
Introduce a new option 'xfuncname' which uses extended regular expressions,
and advertise it _instead_ of funcname. Since most users are on GNU
platforms, the majority of funcname patterns are created and tested there.
Advertising only xfuncname should help to avoid the creation of non-portable
patterns which work with GNU regex but not elsewhere.
Additionally, the extended regular expressions may be less ugly and
complicated compared to the basic RE since many common special operators do
not need to be backslashed.
For example, the GNU Basic RE:
^[ ]*\\(\\(public\\|static\\).*\\)$
becomes the following Extended RE:
^[ ]*((public|static).*)$

The standard libc regex library on OSX does not support alternation
in POSIX Basic Regular Expression mode. This breaks the diff.funcname
functionality on OSX.
To fix this, we use the GNU regex library which is already present in
the compat/ diretory for the MinGW port. However, simply adding compat/
to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/. To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/

Tries to shorten the refname to a non-ambiguous name.
Szeder Gábor noticed that the git bash completion takes a
tremendous amount of time to strip leading components from
heads and tags refs (i.e. refs/heads, refs/tags, ...). He
proposed a new atom called 'refbasename' which removes at
most two leading components from the ref name.
I myself, proposed a more dynamic solution, which strips off
common leading components with the matched pattern.
But the current bash solution and both proposals suffer from
one mayor problem: ambiguous refs.
A ref is ambiguous, if it resolves to more than one full refs.
I.e. given the refs refs/heads/xyzzy and refs/tags/xyzzy. The
(short) ref xyzzy can point to both refs.
( Note: Its irrelevant whether the referenced objects are the
same or not. )
This proposal solves this by checking for ambiguity of the
shorten ref name.
The shortening is done with the same rules for resolving refs
but in the reverse order. The short name is checked if it
resolves to a different ref.
To continue the above example, the output would be like this:
heads/xyzzy
xyzzy
So, if you want just tags, xyzzy is not ambiguous, because it
will resolve to a tag. If you need the heads you get a also
a non-ambiguous short form of the ref.
To integrate this new format into the bash completion to get
only non-ambiguous refs is beyond the scope of this patch.

* jc/maint-log-grep:
log --author/--committer: really match only with name part
diff --cumulative is a sub-option of --dirstat
bash completion: Hide more plumbing commands
When we tried to find commits done by AUTHOR, the first implementation
tried to pattern match a line with "^author .*AUTHOR", which later was
enhanced to strip leading caret and look for "^author AUTHOR" when the
search pattern was anchored at the left end (i.e. --author="^AUTHOR").
This had a few problems:
* When looking for fixed strings (e.g. "git log -F --author=x --grep=y"),
the regexp internally used "^author .*x" would never match anything;
* To match at the end (e.g. "git log --author='google.com>$'"), the
generated regexp has to also match the trailing timestamp part the
commit header lines have. Also, in order to determine if the '$' at
the end means "match at the end of the line" or just a literal dollar
sign (probably backslash-quoted), we would need to parse the regexp
ourselves.
An earlier alternative tried to make sure that a line matches "^author "
(to limit by field name) and the user supplied pattern at the same time.
While it solved the -F problem by introducing a special override for
matching the "^author ", it did not solve the trailing timestamp nor tail
match problem. It also would have matched every commit if --author=author
was asked for, not because the author's email part had this string, but
because every commit header line that talks about the author begins with
that field name, regardleses of who wrote it.
Instead of piling more hacks on top of hacks, this rethinks the grep
machinery that is used to look for strings in the commit header, and makes
sure that (1) field name matches literally at the beginning of the line,
followed by a SP, and (2) the user supplied pattern is matched against the
remainder of the line, excluding the trailing timestamp data.

On a local clone, "git clone" would use the fully DWIMmed path as the origin
URL in the resulting repo. This was slightly inconsistent with the case of a
remote clone where the _given_ URL was used as the origin URL (because the
DWIMming was done remotely, and was therefore not available to "git clone").
This behaviour caused problems when cloning a local non-bare repo with
relative submodule URLs, because these submodule URLs would then be resolved
against the DWIMmed URL (e.g. "/repo/.git") instead of the given URL (e.g.
"/repo").
This patch teaches "git clone" to use the _given_ URL - instead of the
DWIMmed path - as the origin URL. This causes relative submodule URLs to be
resolved correctly, as long the _given_ URL indicates the correct directory
against which the submodule URLs should be resolved.
The patch also updates a testcase that contained the old-style origin URLs.

This new option does essentially the same thing as -m option when checking
unmerged paths out of the index, but it uses the specified style instead
of configured merge.conflictstyle.
Setting "merge.conflictstyle" to "diff3" is usually less useful than using
the default "merge" style, because the latter allows a conflict that
results by both sides changing the same region in a very similar way to
get simplified substancially by reducing the common lines. However, when
one side removed a group of lines (perhaps a function was moved to some
other file) while the other side modified it, the default "merge" style
does not give any clue as to why the hunk is left conflicting. You would
need the original to understand what is going on.
The recommended use would be not to set merge.conflictstyle variable so
that you would usually use the default "merge" style conflict, and when
the result in a path in a particular merge is too hard to understand, use
"git checkout --conflict=diff3 $path" to check it out with the original to
review what is going on.

When the tracked contents have CRLF line endings, colored diff output
shows "^M" at the end of output lines, which is distracting, even though
the pager we use by default ("less") knows to hide them.
The problem is that "less" hides a carriage-return only at the end of the
line, immediately before a line feed. The colored diff output does not
take this into account, and emits four element sequence for each line:
- force this color;
- the line up to but not including the terminating line feed;
- reset color
- line feed.
By including the carriage return at the end of the line in the second
item, we are breaking the smart our pager has in order not to show "^M".
This can be fixed by changing the sequence to:
- force this color;
- the line up to but not including the terminating end-of-line;
- reset color
- end-of-line.
where end-of-line is either a single linefeed or a CRLF pair. When the
output is not colored, "force this color" and "reset color" sequences are
both empty, so we won't have this problem with or without this patch.

<<<<<<<
postimage from one side;
|||||||
shared preimage;
=======
postimage of the other side; and
>>>>>>>
This is an initial step to bring that as an optional feature to git.
Only "git merge-file" has been converted, with "--diff3" option.

This lets you to check out 'our' (or 'their') version of an
unmerged path out of the index while resolving conflicts.

Earlier we made "git checkout $pathspec" to atomically refuse
the operation of $pathspec matched any path with unmerged
stages. This patch allows:
$ git checkout -f a b c
to ignore, instead of error out on, such unmerged paths. The
fix to prevent checkout of an unmerged path from random stages
is still there.

During a conflicted merge when you have unmerged stages for a
path F in the index, if you said:
$ git checkout F
we rewrote F as many times as we have stages for it, and the
last one (typically "theirs") was left in the work tree, without
resolving the conflict.
This fixes it by noticing that a specified pathspec pattern
matches an unmerged path, and by erroring out.

Even after a handfle attempts, match_beginning logic still has corner
cases:
1bf1a85 (apply: treat EOF as proper context., 2006-05-23)
65aadb9 (apply: force matching at the beginning., 2006-05-24)
4be6096 (apply --unidiff-zero: loosen sanity checks ..., 2006-09-17)
ee5a317 (Fix "git apply" to correctly enforce "match ..., 2008-04-06)
This is a tricky piece of code.
We still incorrectly enforce "match_beginning" for -U0 matches.
I noticed this while trying out an example sequence from Clemens Buchacher:
$ echo a >victim
$ git add victim
$ echo b >>victim
$ git diff -U0 >patch
$ cat patch
diff --git i/victim w/victim
index 7898192..422c2b7 100644
--- i/victim
+++ w/victim
@@ -1,0 +2 @@ a
+b
$ git apply --cached --unidiff-zero <patch
$ git show :victim
b
a
The change inserts a new line before the second line, but we insist it to
be applied at the beginning. As the result, the code refuses to apply it
at the original offset, and we end up adding the line at the beginning.
Updates to the test script are by Clemens Buchacher.

--reverse did not interact well with --parents, as the included test
case shows: in a history like
A--B.
\ \
`C--M--D
the command
git rev-list --reverse --parents --full-history HEAD
erroneously lists D as having no parents at all. (Without --reverse,
it correctly lists M.)
This is caused by the machinery driving --reverse: it first grabs all
commits through the normal routines, then runs them through the same
routines again, effectively simplifying them twice.
Fix this by moving the --reverse one level up, into get_revision().
This way we can cleanly grab all commits via the normal calls, then
just pop them off the list one by one without interfering with
get_revision_internal().

When running a command like:

as the non-user formats would do.

Unless used with --cached or grepping on a tree, "git grep" will

This fixes "git diff", "git diff-files" and "git diff-index" to work
correctly under worktree setup. Because diff* family works in many modes
and not all of them require worktree, Junio made a nice summary
(with a little modification from me):
* diff-files is about comparing with work tree, so it obviously needs a
work tree;
* diff-index also does, except "diff-index --cached" or "diff --cached TREE"
* no-index is about random files outside git context, so it obviously
doesn't need any work tree;
* comparing two (or more) trees doesn't;
* comparing two blobs doesn't;
* comparing a blob with a random file doesn't;
