dbc6c74d08 git-svn: handle empty files marked as symlinks in SVN
Broken SVN clients generate empty files with the svn:special set
to '*'.  This attempts to denote a symlink pointing to a file
with an empty path (""), which cannot be generated on a POSIX
system.

Thus, we mimic the behavior of svn(1) and create a zero-byte
file in our tree.

a83c88525e t7700: demonstrate misbehavior of 'repack -a' when local packs exist
The ability to "...fatten [the] local repository by packing everything that
is needed by the local ref into a single new pack, including things that are
borrowed from alternates"[1] is supposed to be provided by the '-a' or '-A'
options to repack when '-l' is not used, but there is a flaw.  For each
pack in the local repository without a .keep file, repack supplies a
--unpacked=<pack> argument to pack-objects.

The --unpacked option to pack-objects, with or without an argument, causes
pack-objects to ignore any object which is packed in a pack not mentioned
in an argument to --unpacked=.  So, if there are local packs, and
'repack -a' is called, then any objects which reside in packs accessible
through alternates will _not_ be packed.  If there are no local packs, then
no --unpacked argument will be supplied, and repack will behave as expected.

There are three flags involved (-w -b and --ignore-space-at-eol) which
makes 8 combinations possible in total, but only 3 cases are tested (none,
-w alone and -b alone).

This adds the other 5 cases.

f0298cf1c6 revision walker: include a detached HEAD in --all
When HEAD is detached, --all should list it, too, logically, as a
detached HEAD is by definition a temporary, unnamed branch.

It is especially necessary to list it when garbage collecting, as
the detached HEAD would be trashed.

Noticed by Thomas Rast.

Note that this affects creating bundles with --all; I contend that it
is a good change to add the HEAD, so that cloning from such a bundle
will give you a current branch.  However, I had to fix t5701 as it
assumed that --all does not imply HEAD.

72183cb297 Fix gitdir detection when in subdir of gitdir
If the current working directory is a subdirectory of the gitdir (e.g.
<repo>/.git/refs/), then setup_git_directory_gently() will climb its
parent directories until it finds itself in a gitdir.  However, no
matter how many parent directories it climbs, it sets
'GIT_DIR_ENVIRONMENT' to ".", which is obviously wrong.

This behaviour affected at least 'git rev-parse --git-dir' and hence
caused some errors in bash completion (e.g. customized command prompt
when on a detached head and completion of refs).

To fix this, we set the absolute path of the found gitdir instead.

b4285c71bc Add ctype test
Manipulating the character class table in ctype.c by hand is error prone.
To ensure that typos are found quickly, add a test program and script.

test-ctype checks the output of the character class macros isspace() et.
al. by applying them on all possible char values and consulting a list of
all characters in the particular class.  It doesn't check tolower() and
toupper(); this could be added later.

The test script t0070-fundamental.sh is created because there is no good
place for the ctype test, yet -- except for t0000-basic.sh perhaps, but
it doesn't run well on Windows, yet.

466ddf90c2 http-push: when making directories, have a trailing slash in the path name
The function lock_remote() sends MKCOL requests to make leading
directories; However, if it does not put a forward slash '/' at the end of
the path, the server sends a 301 redirect.

By leaving the '/' in place, we can avoid this additional step.

Incidentally, at least one version of Curl (7.16.3) does not resend
credentials when it follows a 301 redirect, so this commit also fixes
a bug.

c002922adc expand --pretty=format color options
Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.

Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:

  git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'

to emulate --pretty=oneline, or even

  git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'

if you want to relive the awesomeness of 4-color CGA.

the diff driver's 'wordregex' attribute.  The user can then set the
driver on a file in .gitattributes.  If a regex is given on the

We also provide built-in regexes for the languages that already had

(The patterns are designed to run UTF-8 sequences into a single chunk

2b6a5417d7 color-words: take an optional regular expression describing words
In some applications, words are not delimited by white space.  To
allow for that, you can specify a regular expression describing
what makes a word with

	git diff --color-words='[A-Za-z0-9]+'

Note that words cannot contain newline characters.

As suggested by Thomas Rast, the words are the exact matches of the
regular expression.

Note that a regular expression beginning with a '^' will match only
a word at the beginning of the hunk, not a word at the beginning of
a line, and is probably not what you want.

This commit contains a quoting fix by Thomas Rast.

2e5d2003b2 color-words: change algorithm to allow for 0-character word boundaries
Up until now, the color-words code assumed that word boundaries are
identical to white space characters.

Therefore, it could get away with a very simple scheme: it copied the
hunks, substituted newlines for each white space character, called
libxdiff with the processed text, and then identified the text to
output by the offsets (which agreed since the original text had the
same length).

This code was ugly, for a number of reasons:

- it was impossible to introduce 0-character word boundaries,

- we had to print everything word by word, and

- the code needed extra special handling of newlines in the removed part.

Fix all of these issues by processing the text such that

- we build word lists, separated by newlines,

- we remember the original offsets for every word, and

- after calling libxdiff on the wordlists, we parse the hunk headers, and
  find the corresponding offsets, and then

- we print the removed/added parts in one go.

The pre and post samples in the test were provided by Santi Béjar.

Note that there is some strange special handling of hunk headers where
one line range is 0 due to POSIX: in this case, the start is one too
low.  In other words a hunk header '@@ -1,0 +2 @@' actually means that
the line must be added after the _second_ line of the pre text, _not_
the first.

d911d1465d rebase -i: learn to rebase root commit
Teach git-rebase -i a new option --root, which instructs it to rebase
the entire history leading up to <branch>.  This is mainly for
symmetry with ordinary git-rebase; it cannot be used to edit the root
commit in-place (it requires --onto <newbase>).  Commits that already
exist in <newbase> are skipped.

In the normal mode of operation, this is fairly straightforward.  We
run cherry-pick in a loop, and cherry-pick has supported picking the
root commit since f95ebf7 (Allow cherry-picking root commits,
2008-07-04).

In --preserve-merges mode, we track the mapping from old to rewritten
commits and use it to update the parent list of each commit.  In this
case, we define 'rebase -i -p --root --onto $onto $branch' to rewrite
the parent list of all root commit(s) on $branch to contain $onto
instead.

One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN.  You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection.  This previously had to
be done by cherry-picking the root commit manually.

7eb5bbdb64 t7501-commit.sh: explicitly check that -F prevents invoking the editor
The "--signoff" test case in t7500-commit.sh was setting VISUAL while
using -F -, which indeed tested that the editor is not spawned with -F.
However, having it there was confusing, since there was no obvious reason
to the casual reader for it to be there.

This commits removes the setting of VISUAL from the --signoff test, and
adds in t7501-commit.sh a dedicated test case, where the rest of tests for
-F are.

d3240d935c filter-branch: add git_commit_non_empty_tree and --prune-empty.
git_commit_non_empty_tree is added to the functions that can be run from
commit filters. Its effect is to commit only commits actually touching the
tree and that are not merge points either.

The option --prune-empty is added. It defaults the commit-filter to
'git_commit_non_empty_tree "$@"', and can be used with any other
combination of filters, except --commit-hook that must used
'git_commit_non_empty_tree "$@"' where one puts 'git commit-tree "$@"'
usually to achieve the same result.

64912a67a4 Resurrect "git apply --flags -" to read from the standard input
The previous "parse-opt"ification broke git-apply reading from the
standard input.  "git apply A - C <B" is supposed to read patches from
files A, B and C in this order.

Before "parse-opt"ification, we used be able to:

	git apply --stat - --apply <A B

to read the patch from file A, showing only the diffstat, and then read the
patch from file B, showing the diffstat and actually applying it.  Even
with this fix we cannot do that anymore, but that is so crazy use case I
do not think anybody sane relied on such a broken behaviour.

837e5fe95d unpack-trees: fix path search bug in verify_absent
Commit 0cf73755 (unpack-trees.c: assume submodules are clean during
check-out) changed an argument to verify_absent from 'path' to 'ce',
which is however shadowed by a local variable of the same name.

The bug triggers if verify_absent is used on a tree entry, for which
the index contains one or more subsequent directories of the same
length. The affected subdirectories are removed from the index. The
testcase included in this commit bisects to 55218834 (checkout: do not

1f7903a371 builtin-apply: prevent non-explicit permission changes
A git patch that does not change the executable bit records the mode bits
on its "index" line.  "git apply" used to interpret this mode exactly the
same way as it interprets the mode recorded on "new mode" line, as the
wish by the patch submitter to set the mode to the one recorded on the
line.

The reason the mode does not agree between the submitter and the receiver
in the first place is because there is _another_ commit that only appears
on one side but not the other since their histories diverged, and that
commit changes the mode.  The patch has "index" line but not "new mode"
line because its change is about updating the contents without affecting
the mode.  The application of such a patch is an explicit wish by the
submitter to only cherry-pick the commit that updates the contents without
cherry-picking the commit that modifies the mode.  Viewed this way, the
current behaviour is problematic, even though the command does warn when
the mode of the path being patched does not match this mode, and a careful
user could detect this inconsistencies between the patch submitter and the
patch receiver.

This changes the semantics of the mode recorded on the "index" line;
instead of interpreting it as the submitter's wish to set the mode to the
recorded value, it merely informs what the mode submitter happened to
have, and the presense of the "index" line is taken as submitter's wish to
keep whatever the mode is on the receiving end.

This is based on the patch originally done by Alexander Potashev with a
minor fix; the tests are mine.

08fc060865 git-sh-setup: Fix scripts whose PWD is a symlink into a git work-dir
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
patch makes an exception for files which will be textconv'd,
and actually performs the textconv before generating the
diff.

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".

0c01857df5 diff: fix handling of binary rewrite diffs
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.

553589f782 git-svn: Make following parents atomic
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.

dbc2fb6b84 "git diff <tree>{3,}": do not reverse order of arguments
According to the message of commit 0fe7c1de16f71312e6adac4b85bddf0d62a47168,
"git diff" with three or more trees expects the merged tree first followed by
the parents, in order.  However, this command reversed the order of its
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.

a0fbc87cff git-svn: Make branch use correct svn-remote
The 'branch' subcommand incorrectly had the svn-remote to use hardcoded
as 'svn', the default remote name.  This meant that branches derived
from other svn-remotes would try to use the branch and tag configuration
for the 'svn' remote, potentially copying would-be branches to the wrong
place in SVN, into the branch namespace for another project.

Fix this by using the remote name extracted from the svn info for the
specified git ref.  Add a testcase for this behaviour.

1a66a489d0 bisect: fix "git bisect skip <commit>" and add tests cases
The patch that allows "git bisect skip" to be passed a range of
commits using the "<commit1>..<commit2>" notation is flawed because
it introduces a regression when it was passed a simple rev or commit.

"git bisect skip <commit>" doesn't work any more, because <commit>
is quoted but not properly unquoted.

This patch fixes that and add tests cases to better check when it is
passed commits and range of commits.

While at it, this patch also properly quotes the non range arguments

This uses the extended index flag mechanism introduced earlier to mark

The logic to detect an "intent to add" entry for the purpose of allowing
"git rm --cached $path" is tightened to check not just for a staged empty
blob, but with the CE_INTENT_TO_ADD bit.  This protects an empty blob that
was explicitly added and then modified in the work tree from being dropped
with this sequence:

	$ >empty
	$ git add empty
	$ echo "non empty" >empty
	$ git rm --cached empty

0b38227f28 commit: Fix stripping of patch in verbose mode.
When the "-v" option is given, we put diff of what is to be committed into
the commit template, and then strip it back out again after the user has
edited it.

We used to look for the diff by searching for the "diff --git a/"
header. With diff.mnemonicprefix set in the configuration, however, this
pattern does not match.  The pattern is loosened to cover this case.

Also, if the user puts their own diff in the message (e.g., as a sample
output), then we will accidentally trigger the pattern, removing part of
their output.

We can avoid doing this stripping altogether if the user didn't use "-v"
in the first place, so we know that any match we find will be a false
positive.

986e82396a receive-pack: detect push to current branch of non-bare repo
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".

b2dc968e60 t5516: refactor oddball tests
t5516 sets up some utility functions for starting each test
with a clean slate. However, there were a few tests added
that do not use these functions, but instead make their own
repositories.

Let's bring these in line with the rest of the tests. Not
only do we reduce the number of lines, but these tests will
benefit from any further enhancements to the utility
scripts.

The conversion is pretty straightforward. Most of the tests
created a parent/child clone relationship, for which we now
use 'testrepo' as the parent.  One test looked in testrepo,
but relied on previous tests to have set it up; it now sets
up testrepo explicitly, which makes it a bit more robust to
changes in the script, as well.

aab5720551 git-svn: respect i18n.commitencoding config
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, ...).

0e8189e270 close another possibility for propagating pack corruption
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.

c7534ef4a1 userdiff: require explicitly allowing textconv
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

suffered from being too coarse-grained.

04427ac848 refactor userdiff textconv code
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)

2b5c208f5b improve index-pack tests
Commit 9441b61dc5 introduced serious bugs in index-pack which are
described and fixed by commit ce3f6dc655.  However, despite the
boldness of those bugs, the test suite still passed.

This improves t5302-pack-index.sh so to ensure a much better code
path coverage.  With commit ce3f6dc655 reverted, 17 of the 26 tests
do fail now.

20244ea2d0 git-remote: list branches in vertical lists
Previously, branches were listed on a single line in each section. But
if there are many branches, then horizontal, line-wrapped lists are very
inconvenient to scan for a human. This makes the lists vertical, i.e one
branch per line is printed.

Since "git remote" is porcelain, we can easily make this
backwards-incompatible change.

f55527f802 rm: loosen safety valve for empty files
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.
