at that stage can be caught.
- Use <<-\EOF in preference to <<EOF to save readers the trouble of

The rev-list output in this test depends on the details of test_tick's
dummy dates and the choice of hash function. Worse, it depends on the
order and nature of commits made in the earlier tests, so adding new
tests or rearranging existing ones breaks it.
It would be nice to check that "git commit" and commit-tree name
objects consistently and that commit objects' text is as documented,
but this particular test checks everything at once and hence is not a
robust test for that. Remove it.

In prepare_index(), we refresh the index, and then write it to disk if
this changed the index data. After running hooks we re-read the index
and compute the root tree sha1 with the cache-tree machinery.
This gives us a mostly free opportunity to write up-to-date cache-tree
data: we can compute it in prepare_index() immediately before writing
the index to disk.
If we do this, we were going to write the index anyway, and the later
cache-tree update has no further work to do. If we don't do it, we
don't do any extra work, though we still don't have have cache-tree
data after the commit.
The only case that suffers badly is when the pre-commit hook changes
many trees in the index. I'm writing this off as highly unusual.

The cache-tree optimization originally helped speed up write-tree
operation. However, many commands no longer properly maintain -- or
use an opportunity to cheaply generate -- the cache-tree data. In
particular, this affects commit, checkout and reset. The notable
examples that *do* write cache-tree data are read-tree and write-tree.
This sadly means most people no longer benefit from the optimization,
as they would not normally use the plumbing commands.

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

When git apply is passed something that is not a patch, it does not produce
an error message or exit with a non-zero status if it was not actually
"applying" the patch i.e. --check or --numstat etc were supplied on the
command line.
Fix this by producing an error when apply fails to find any hunks whatsoever
while parsing the patch.
This will cause some of the output formats (--numstat, --diffstat, etc) to
produce an error when they formerly would have reported zero changes and
exited successfully. That seems like the correct behavior though. Failure
to recognize the input as a patch should be an error.

This fixes the bug uncovered by the tests added in the previous two patches.
When an existing notes ref was loaded into the fast-import machinery, the
num_notes counter associated with that ref remained == 0, even though the
true number of notes in the loaded ref was higher. This caused a fanout
level of 0 to be used, although the actual fanout of the tree could be > 0.
Manipulating the notes tree at an incorrect fanout level causes removals to
silently fail, and modifications of existing notes to instead produce an
additional note (leaving the old object in place at a different fanout level).
This patch fixes the bug by explicitly counting the number of notes in the
notes tree whenever it looks like the num_notes counter could be wrong (when
num_notes == 0). There may be false positives (i.e. triggering the counting
when the notes tree is truly empty), but in those cases, the counting should
not take long.

The previous patch exposed a bug in fast-import where _removing_ an existing

prior to this fast-import run).
This patch demostrates the same issue when _changing_ an existing note
(subject to the same circumstances).

There is a bug in fast-import where the fanout levels of an existing notes
tree being loaded into the fast-import machinery is disregarded. Instead, any
tree loaded is assumed to have a fanout level of 0. If the true fanout level
is deeper, any attempt to remove a note from that tree will silently fail
(as the note will not be found at fanout level 0).
However, this bug was covered up by the way in which the t9301 testcase was
written: When generating the fast-import commands to test mass removal of
notes, we appended these commands to an already existing 'input' file which
happened to already contain the fast-import commands used in the previous
subtest to generate the very same notes tree. This would normally be harmless
(but suboptimal) as the notes created were identical to the notes already
present in the notes tree. But the act of repeating all the notes additions
caused the internal fast-import data structures to recalculate the fanout,
instead of hanging on to the initial (incorrect) fanout (that causes the bug
described above). Thus, the subsequent removal of notes in the same 'input'
file would succeed, thereby covering up the bug described above.
This patch creates a new 'input' file instead of appending to the file from
the previous subtest. Thus, we end up properly testing removal of notes that
were added by a previous fast-import command. As a side effect, the notes
removal can no longer refer to commits using the marks set by the previous
fast-import run, instead the commits names must be referenced directly.
The underlying fast-import bug is still present after this patch, but now we
have at least uncovered it. Therefore, the affected subtests are labeled as
expected failures until the underlying bug is fixed.

The "git cherry-pick --abort" command currently renames the
.git/sequencer directory to .git/sequencer-old instead of removing it
on success due to an accident. cherry-pick --abort is designed to
work in three steps:
1) find which commit to roll back to
2) call "git reset --merge <commit>" to move to that commit
3) remove the .git/sequencer directory
But the careless author forgot step 3 entirely. The only reason the
command worked anyway is that "git reset --merge <commit>" renames the
.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.
By running "git cherry-pick --abort", the operator has clearly
indicated that she is not planning to continue cherry-picking. Remove
the (renamed) .git/sequencer directory as intended all along.

When conflicts are encountered while reverting a commit, it can be

to produce a copy of the patch to refer to while resolving conflicts:
$ git revert 2eceb2a8
error: could not revert 2eceb2a8... awesome, buggy feature
$ git show -R REVERT_HEAD >the-patch
$ edit $(git diff --name-only)
Set a REVERT_HEAD pseudoref when "git revert" does not make a commit,
for cases like this. This also makes it possible for scripts to
distinguish between a revert that encountered conflicts and other
sources of an unmerged index.
After successfully committing, resetting with "git reset", or moving
to another commit with "git checkout" or "git reset", the pseudoref is
no longer useful, so remove it.

The option to "git cherry-pick" and "git revert" to discard the
sequencer state introduced by v1.7.8-rc0~141^2~6 (revert: Introduce
--reset to remove sequencer state, 2011-08-04) has a confusing name.
Change it now, while we still have the time.
The new name for "cherry-pick, please get out of my way, since I've
long forgotten about the sequence of commits I was cherry-picking when
you wrote that old .git/sequencer directory" is --quit. Mnemonic:
this is analagous to quiting a program the user is no longer using ---
we just want to get out of the multiple-command cherry-pick procedure
and not to reset HEAD or rewind any other old state.
The "--reset" option is kept as a synonym to minimize the impact. We
might consider dropping it for simplicity in a separate patch, though.
Adjust documentation and tests to use the newly preferred name (--quit)
instead of --reset. While at it, let's clarify the short descriptions
of these operations in "-h" output.
Before:
--reset forget the current operation
--continue continue the current operation
After:
--quit end revert or cherry-pick sequence
--continue resume revert or cherry-pick sequence

Usually git is careful not to allow clients to fetch
arbitrary objects from the database; for example, objects
received via upload-pack must be reachable from a ref.
Upload-archive breaks this by feeding the client's tree-ish
directly to get_sha1, which will accept arbitrary hex sha1s,
reflogs, etc.
This is not a problem if all of your objects are publicly
reachable anyway (or at least public to anybody who can run
upload-archive). Or if you are making the repo available by
dumb protocols like http or rsync (in which case the client
can read your whole object db directly).
But for sites which allow access only through smart
protocols, clients may be able to fetch trees from commits
that exist in the server's object database but are not
referenced (e.g., because history was rewound).
This patch tightens upload-archive's lookup to use dwim_ref
rather than get_sha1. This means a remote client can only
fetch the tip of a named ref, not an arbitrary sha1 or
reflog entry.
This also restricts some legitimate requests, too:
1. Reachable non-tip commits, like:
git archive --remote=$url v1.0~5
2. Sub-trees of reachable commits, like:
git archive --remote=$url v1.7.7:Documentation
Local requests continue to use get_sha1, and are not
restricted at all.

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation

so the fetch rules table did not include "refs/remotes/%.*s/HEAD".
When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.
Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.
So for the same reason as we added rule to allow "git fetch $there v1.0"

estimate_cache_size() tries to guess how much memory is needed for the
in-memory representation of an index file. It does that by using the
file size, the number of entries and the difference of the sizes of the
on-disk and in-memory structs -- without having to check the length of
the name of each entry, which varies for each entry, but their sums are
the same no matter the representation.
Except there can be a difference. First of all, the size is really
calculated by ce_size and ondisk_ce_size based on offsetof(..., name),
not sizeof, which can be different. And entries are padded with 1 to 8
NULs at the end (after the variable name) to make their total length a
multiple of eight.
So in order to allocate enough memory to hold the index, change the
delta calculation to be based on offsetof(..., name) and round up to
the next multiple of eight.
On a 32-bit Linux, this delta was used before:
sizeof(struct cache_entry) == 72
sizeof(struct ondisk_cache_entry) == 64
---
8
The actual difference for an entry with a filename length of one was,
however (find the definitions are in cache.h):
offsetof(struct cache_entry, name) == 72
offsetof(struct ondisk_cache_entry, name) == 62
ce_size == (72 + 1 + 8) & ~7 == 80
ondisk_ce_size == (62 + 1 + 8) & ~7 == 64
---
16
So eight bytes less had been allocated for such entries. The new
formula yields the correct delta:
(72 - 62 + 7) & ~7 == 16

One of the filetypes that p4 supports is utf16. Its behavior is
odd in this case. The data delivered through "p4 -G print" is
not encoded in utf16, although "p4 print -o" will produce the
proper utf16-encoded file.
When dealing with this filetype, discard the data from -G, and
instead read the contents directly.
An alternate approach would be to try to encode the data in
python. That worked for true utf16 files, but for other files
marked as utf16, p4 delivers mangled text in no recognizable encoding.
Add a test case to check utf16 handling, and +k and +ko handling.

If the user gave us refspecs on the command line, we should use those
when deciding whether to prune a ref instead of relying on the
refspecs in the config.
Previously, running
git fetch --prune origin refs/heads/master:refs/remotes/origin/master
would delete every other ref under the origin namespace because we
were using the refspec to filter the available refs but using the
configured refspec to figure out if a ref had been deleted on the
remote. This is clearly the wrong thing to do.
Change prune_refs and get_stale_heads to simply accept a list of
references and a list of refspecs. The caller of either function needs
to decide what refspecs should be used to decide whether a ref is

cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30) broke
the expansion of aliases.
This was caused by treating %config_path_settings, newly introduced in
said patch, like %config_bool_settings instead of like %config_settings.
Copy from %config_settings, making it more readable.
While at it add basic test for expansion of aliases, and for path
expansion, which would catch this error.
Nb. there were a few issues that were responsible for this error:
1. %config_bool_settings and %config_settings despite similar name have
different semantic.
%config_bool_settings values are arrays where the first element is
(reference to) the variable to set, and second element is default
value... which admittedly is a bit cryptic. More readable if more
verbose option would be to use hash reference, e.g.:
my %config_bool_settings = (
"thread" => { variable => \$thread, default => 1},
[...]
%config_settings values are either either reference to scalar variable
or reference to array. In second case it means that option (or config
option) is multi-valued. BTW. this is similar to what Getopt::Long does.
2. In cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30)
the setting "aliasesfile" was moved from %config_settings to newly
introduced %config_path_settings. But the loop that parses settings
from %config_path_settings was copy'n'pasted *wrongly* from
%config_bool_settings instead of from %config_settings.
It looks like cec5dae author cargo-culted this change...

submodule merge search runs during the temporary merge of the two merge
bases (b,c) and prints out a suggestion that is not meaningful to the
user. Then during the main merge the submodule merge search runs again
but dies with the message

We should be able to ask for a config value both by its
canonical all-lowercase name (as git does internally), as
well as by random mixed-case (which will be canonicalized by
git-config for us).
Subsections are a tricky point, though. Since we have both
[section "Foo"]
and
[section.Foo]
you might want git-config to canonicalize the subsection or
not, depending on which you are expecting. But there's no
way to communicate this; git-config sees only the key, and
doesn't know which type of section name will be in the
config file.
So it must leave the subsection intact, and it is up to the
caller to provide a canonical version of the subsection if
they want to match the latter form.

When core.ignorecase is true, the file globs configured in the
.gitattributes file should be matched case-insensitively against the paths
in the working directory. Let's do so.
Plus, add some tests.
The last set of tests is performed only on a case-insensitive filesystem.
Those tests make sure that git handles the case where the .gitignore file
resides in a subdirectory and the user supplies a path that does not match
the case in the filesystem. In that case^H^H^H^Hsituation, part of the
path supplied by the user is effectively interpreted case-insensitively,
and part of it is dependent on the setting of core.ignorecase. git will
currently only match the portion of the path below the directory holding
the .gitignore file according to the setting of core.ignorecase.
This is also partly future-proofing. Currently, git builds the attr stack
based on the path supplied by the user, so we don't have to do anything
special (like use strcmp_icase) to handle the parts of that path that don't
match the filesystem with respect to case. If git instead built the attr
stack by scanning the repository, then the paths in the origin field would
not necessarily match the paths supplied by the user. If someone makes a
change like that in the future, these tests will notice.

Add the option -W/--function-context to git diff. It is similar to
the same option of git grep and expands the context of change hunks
so that the whole surrounding function is shown. This "natural"
context can allow changes to be understood better.
Note: GNU patch doesn't like diffs generated with the new option;
it seems to expect context lines to be the same before and after
changes. git apply doesn't complain.
This implementation has the same shortcoming as the one in grep,
namely that there is no way to explicitly find the end of a
function. That means that a few lines of extra context are shown,
right up to the next recognized function begins. It's already
useful in its current form, though.
The function get_func_line() in xdiff/xemit.c is extended to work
forward as well as backward to find post-context as well as
pre-context. It returns the position of the first found matching
line. The func_line parameter is made optional, as we don't need
it for -W.
The enhanced function is then used in xdl_emit_diff() to extend
the context as needed. If the added context overlaps with the
next change, it is merged into the current hunk.

Since much of the infrastructure does not work correctly with

Similarly, change "git check-ref-format" to reject unnormalized
refnames by default. But add an option --normalize, which causes "git
check-ref-format" to normalize the refname before checking its format,

Change check_ref_format() to take a flags argument that indicates what
is acceptable in the reference name (analogous to "git
check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This
is more convenient for callers and also fixes a failure in the test
suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.
Also rename check_ref_format() to check_refname_format() to make it
obvious that it deals with refnames rather than references themselves.

Also add tests of the new options. (Actually, one big reason to add
the new options is to make it easy to test check_ref_format(), though
the options should also be useful to other scripts.)
Interpret the result of check_ref_format() based on which types of
refnames are allowed. However, because check_ref_format() can only
return a single value, one test case is still broken. Specifically,
the case "git check-ref-format --onelevel '*'" incorrectly succeeds
because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this
refname even though the refname is also CHECK_REF_FORMAT_WILDCARD.
The type of check that leads to this failure is used elsewhere in
"real" code and could lead to bugs; it will be fixed over the next few
commits.

In a working tree of a git managed repository, "grep --untracked" would
find the specified patterns from files in untracked files in addition to
its usual behaviour of finding them in the tracked files.
By default, when working with "--no-index" option, "grep" does not pay
attention to .gitignore mechanism. "grep --no-index --exclude-standard"
can be used to tell the command to use .gitignore and stop reporting hits
from files that would be ignored. Also, when working without "--no-index",
"grep" honors .gitignore mechanism, and "grep --no-exclude-standard" can
be used to tell the command to include hits from files that are ignored.

When a push specifies deletion of non-existent refs, the post post-receive and
post-update hooks receive them as input/arguments.
For instance, for the following push, where refs/heads/nonexistent is a ref
which does not exist on the remote side:
git push origin :refs/heads/nonexistent
the post-receive hook receives from standard input:
<null-sha1> SP <null-sha1> SP refs/heads/nonexistent
and the post-update hook receives as arguments:
refs/heads/nonexistent
which does not make sense since it is a no-op.
Teach receive-pack not to pass non-existent refs to the post-receive and
post-update hooks. If the push only attempts to delete non-existent refs,
these hooks are not even called.
The update and pre-receive hooks are still notified about attempted
deletion of non-existent refs to give them a chance to inspect the
situation and act on it.

Checking paths out of a tree is (currently) defined to do:
- Grab the paths from the named tree that match the given pathspec,
and add them to the index;
- Check out the contents from the index for paths that match the
pathspec to the working tree; and while at it
- If the given pathspec did not match anything, suspect a typo from the
command line and error out without updating the index nor the working
tree.
Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running
$ git checkout other dir
would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.
Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.
In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.
In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.
This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

absence of output, such as the '! grep ...' that are quite prevalent
in t4014.
Introduce a helper check_patch() that checks that at least From, Date
and Subject are present, thus making sure it looks vaguely like a
patch (or cover letter) email. Then insert calls to it in all tests
that do have positive checks for content.
This makes two of the tests fail. Mark them as such; they'll be
fixed in a moment.

The two new stash options --include-untracked and --all do not remove the

not remove directories.

After an "exec false" stops the rebase and gives the control back to

with this message, which may technically be correct, but does not point
at the real problem:
.../git-rebase--interactive: line 774: .../.git/rebase-merge/author-script: No such file or directory
We could try auto-amending HEAD, but this goes against the logic of
.git/rebase-merge/author-script (see also the testcase 'auto-amend only
edited commits after "edit"' in t3404-rebase-interactive.sh) to
auto-amend something the user hasn't explicitely asked to edit.
Instead of doing anything automatically, detect the situation and give a

case '. "$author_script"' fails, which now corresponds to really weird

Cloning from a local repository blindly copies or hardlinks all the files
under objects/ hierarchy. This results in two issues:
- If the repository cloned has an "objects/info/alternates" file, and the
command line of clone specifies --reference, the ones specified on the
command line get overwritten by the copy from the original repository.
- An entry in a "objects/info/alternates" file can specify the object
stores it borrows objects from as a path relative to the "objects/"
directory. When cloning a repository with such an alternates file, if
the new repository is not sitting next to the original repository, such
relative paths needs to be adjusted so that they can be used in the new
repository.
This updates add_to_alternates_file() to take the path to the alternate
object store, including the "/objects" part at the end (earlier, it was
taking the path to $GIT_DIR and was adding "/objects" itself), as it is
technically possible to specify in objects/info/alternates file the path
of a directory whose name does not end with "/objects".

"git branch -M <foo> <current-branch>" allows updating the current branch
which HEAD points, without the necessary house-keeping that git reset
normally does to make this operation sensible. It also leaves the reflog
in a confusing state (you would be warned when trying to read it).
"git checkout -B <current branch> <foo>" is also partly vulnerable to this
bug; due to inconsistent pre-flight checks it would perform half of its
task and then abort just before rewriting the branch. Again this
manifested itself as the index file getting out-of-sync with HEAD.
"git branch -f" already guarded against this problem, and aborts with
a fatal error.
Update "git branch -M", "git checkout -B" and "git branch -f" to share the
same check before allowing a branch to be created. These prevent you from
updating the current branch.
We considered suggesting the use of "git reset" in the failure message
but concluded that it was not possible to discern what the user was

When working with submodules it is easy to forget to push a

When we read a color value either from a config file or from
the command line, we use git_config_colorbool to convert it
from the tristate always/never/auto into a single yes/no
boolean value.
This has some timing implications with respect to starting
a pager.
If we start (or decide not to start) the pager before
checking the colorbool, everything is fine. Either isatty(1)
will give us the right information, or we will properly
check for pager_in_use().
However, if we decide to start a pager after we have checked
the colorbool, things are not so simple. If stdout is a tty,
then we will have already decided to use color. However, the
user may also have configured color.pager not to use color
with the pager. In this case, we need to actually turn off
color. Unfortunately, the pager code has no idea which color
variables were turned on (and there are many of them
throughout the code, and they may even have been manipulated
after the colorbool selection by something like "--color" on
the command line).
This bug can be seen any time a pager is started after
config and command line options are checked. This has
affected "git diff" since 89d07f7 (diff: don't run pager if
user asked for a diff style exit code, 2007-08-12). It has
also affect the log family since 1fda91b (Fix 'git log'
early pager startup error case, 2010-08-24).
This patch splits the notion of parsing a colorbool and
actually checking the configuration. The "use_color"
variables now have an additional possible value,
GIT_COLOR_AUTO. Users of the variable should use the new
"want_color()" wrapper, which will lazily determine and
cache the auto-color decision.

We have always set a global "spawned_pager" variable when we
start the pager. This lets us make the auto-color decision
later in the program as as "we are outputting to a terminal,
or to a pager which can handle colors".
Commit 6e9af86 added support for the GIT_PAGER_IN_USE
environment variable. An external program calling git (e.g.,
git-svn) could set this variable to indicate that it had
already started the pager, and that the decision about
auto-coloring should take that into account.
However, 6e9af86 failed to do the reverse, which is to tell
external programs when git itself has started the pager.
Thus a git command implemented as an external script that
has the pager turned on (e.g., "git -p stash show") would
not realize it was going to a pager, and would suppress
colors.
This patch remedies that; we always set GIT_PAGER_IN_USE
when we start the pager, and the value is respected by both
this program and any spawned children.

There are a few common tasks when working with configuration
variables in tests; this patch aims to make them a little
easier to write and less error-prone.
When setting a variable, you should typically make sure to
clean it up after the test is finished, so as not to pollute
other tests. Like:
test_when_finished 'git config --unset foo.bar' &&
git config foo.bar baz
This patch lets you just write:
test_config foo.bar baz
When clearing a variable that does not exist, git-config
will report a specific non-zero error code. Meaning that
tests which call "git config --unset" often either rely on
the prior tests having actually set it, or must use
test_might_fail. With this patch, the previous:
test_might_fail git config --unset foo.bar
becomes:
test_unconfig foo.bar
Not only is this easier to type, but it is more robust; it
will correctly detect errors from git-config besides "key
was not set".

To produce deltas for tree objects fast-import tracks two versions
of tree's entries - base and current one. Base version stands both
for a delta base of this tree, and for a entry inside a delta base
of a parent tree. So care should be taken to keep it in sync.
tree_content_set cuts away a whole subtree and replaces it with a
new one (or NULL for lazy load of a tree with known sha1). It
keeps a base sha1 for this subtree (needed for parent tree). And
here is the problem, 'subtree' tree root doesn't have the implied
base version entries.
Adjusting the subtree to include them would mean a deep rewrite of
subtree. Invalidating the subtree base version would mean recursive
invalidation of parents' base versions. So just mark this tree as
do-not-delta me. Abuse setuid bit for this purpose.
tree_content_replace is the same as tree_content_set except that is
is used to replace the root, so just clearing base sha1 here (instead
of setting the bit) is fine.

The results for the test indicate that the merge should

both sides renamed "a" to the same destination, we will end

But what about what's left? One side (the rename only),
replaced "a" with nothing. The other side replaced it with a
symlink. The common base must also be nothing, because any
"a" before this was meaningless (it was totally unrelated
content that ended up getting renamed).
The only sensible resolution is to keep the symlink. The
rename-only side didn't touch the content versus the common
base, and the other side added content. The 3-way merge
dictates that we take the side with a change.
And this gives the overall merge an intuitive result. One
side made one change (a rename), and the other side made two
changes: an identical rename, and an addition (that just
happened to be at the same spot). The end result should
contain both changes.

Our previous conflict resolution for renaming two different files to the
same name ignored the fact that each of those files may have modifications
from both sides of history to consider. We need to do a three-way merge
for each of those files, and then handle the conflict of both sets of
merged contents trying to be recorded with the same name.
It is important to note that this changes our strategy in the recursive
case. After doing a three-way content merge of each of the files
involved, we still are faced with the fact that we are trying to put both
of the results (including conflict markers) into the same path. We could
do another two-way merge, but I think that becomes confusing. Also,
taking a hint from the modify/delete and rename/delete cases we handled
earlier, a more useful "common ground" would be to keep the three-way
content merge but record it with the original filename. The renames can
still be detected, we just allow it to be done in the o->call_depth=0
case. This seems to result in simpler & easier to understand merge
conflicts as well, as evidenced by some of the changes needed in our
testsuite in t6036. (However, it should be noted that this change will
cause problems those renames also occur along with a file being added
whose name matches the source of the rename. Since git currently cannot
detect rename/add-source situations, though, this codepath is not
currently used for those cases anyway.

When renaming one file to two files, we really should be doing a content
merge. Also, in the recursive case, undoing the renames and recording the
merged file in the index with the source of the rename (while deleting
both destinations) allows the renames to be re-detected in the
non-recursive merge and will result in fewer spurious conflicts.

When o->call_depth>0 and we have conflicts, we try to find "middle ground"
when creating the virtual merge base. In the case of content conflicts,
this can be done by doing a three-way content merge and using the result.
In all parts where the three-way content merge is clean, it is the correct
middle ground, and in parts where it conflicts there is no middle ground
but the conflict markers provide a good compromise since they are unlikely
to accidentally match any further changes.
In the case of a modify/delete conflict, we cannot do the same thing.
Accepting either endpoint as the resolution for the virtual merge base
runs the risk that when handling the non-recursive case we will silently
accept one person's resolution over another without flagging a conflict.
In this case, the closest "middle ground" we have is actually the merge
base of the candidate merge bases. (We could alternatively attempt a
three way content merge using an empty file in place of the deleted file,
but that seems to be more work than necessary.)

In 882fd11 (merge-recursive: Delay content merging for renames 2010-09-20),
there was code that checked for whether we could skip updating a file in
the working directory, based on whether the merged version matched the
current working copy. Due to the desire to handle directory/file conflicts
that were resolvable, that commit deferred content merging by first
updating the index with the unmerged entries and then moving the actual
merging (along with the skip-the-content-update check) to another function
that ran later in the merge process. As part moving the content merging
code, a bug was introduced such that although the message about skipping
the update would be printed (whenever GIT_MERGE_VERBOSITY was sufficiently
high), the file would be unconditionally updated in the working copy
anyway.
When we detect that the file does not need to be updated in the working
copy, update the index appropriately and then return early before updating
the working copy.
Note that there was a similar change in b2c8c0a (merge-recursive: When we
detect we can skip an update, actually skip it 2011-02-28), but it was
reverted by 6db4105 (Revert "Merge branch 'en/merge-recursive'"
2011-05-19) since it did not fix both of the relevant types of unnecessary
update breakages and, worse, it made use of some band-aids that caused
other problems. The reason this change works is due to the changes earlier
in this series to (a) record_df_conflict_files instead of just unlinking
them early, (b) allowing make_room_for_path() to remove D/F entries,
(c) the splitting of update_stages_and_entry() to have its functionality
called at different points, and (d) making the pathnames of the files
involved in the merge available to merge_content().

The code for rename_rename_2to1 conflicts (two files both being renamed to
the same filename) was dead since the rename/add path was always being
independently triggered for each of the renames instead. Further,
reviving the dead code showed that it was inherently buggy and would
always segfault -- among a few other bugs.
Move the else-if branch for the rename/rename block before the rename/add
block to make sure it is checked first, and fix up the rename/rename(2to1)

In the recursive case (o->call_depth > 0), we do not modify the working
directory. However, when o->call_depth==0, file renames can mean we need
to delete the old filename from the working copy. Since there have been
lots of changes and mistakes here, let's go through the details. Let's
start with a simple explanation of what we are trying to achieve:
Original goal: If a file is renamed on the side of history being merged
into head, the filename serving as the source of that rename needs to be
removed from the working directory.
The path to getting the above statement implemented in merge-recursive took
several steps. The relevant bits of code may be instructive to keep in
mind for the explanation, especially since an English-only description
involves double negatives that are hard to follow. These bits of code are:
int remove_file(..., const char *path, int no_wd)
{
...
int update_working_directory = !o->call_depth && !no_wd;
and
remove_file(o, 1, ren1_src, <expression>);
Where the choice for <expression> has morphed over time:
65ac6e9 (merge-recursive: adjust to loosened "working file clobbered"
check 2006-10-27), introduced the "no_wd" parameter to remove_file() and
used "1" for <expression>. This meant ren1_src was never deleted, leaving
it around in the working copy.
In 8371234 (Remove uncontested renamed files during merge. 2006-12-13),
<expression> was changed to "index_only" (where index_only ==
!!o->call_depth; see b7fa51da). This was equivalent to using "0" for
<expression> (due to the early logic in remove_file), and is orthogonal to
the condition we actually want to check at this point; it resulted in the
source file being removed except when index_only was false. This was
problematic because the file could have been renamed on the side of history
including head, in which case ren1_src could correspond to an untracked
file that should not be deleted.
In 183d797 (Keep untracked files not involved in a merge. 2007-02-04),
<expression> was changed to "index_only || stage == 3". While this gives
correct behavior, the "index_only ||" portion of <expression> is
unnecessary and makes the code slightly harder to follow.
There were also two further changes to this expression, though without
any change in behavior. First in b7fa51d (merge-recursive: get rid of the
index_only global variable 2008-09-02), it was changed to "o->call_depth
|| stage == 3". (index_only == !!o->call_depth). Later, in 41d70bd6
(merge-recursive: Small code clarification -- variable name and comments),
this was changed to "o->call_depth || renamed_stage == 2" (where stage was
renamed to other_stage and renamed_stage == other_stage ^ 1).
So we ended with <expression> being "o->call_depth || renamed_stage == 2".
But the "o->call_depth ||" piece was unnecessary. We can remove it,
leaving us with <expression> being "renamed_stage == 2". This doesn't
change behavior at all, but it makes the code clearer. Which is good,
because it's about to get uglier.
Corrected goal: If a file is renamed on the side of history being merged
into head, the filename serving as the source of that rename needs to be
removed from the working directory *IF* that file is tracked in head AND
the file tracked in head is related to the original file.
Note that the only difference between the original goal and the corrected
goal is the two extra conditions added at the end. The first condition is
relevant in a rename/delete conflict. If the file was deleted on the
HEAD side of the merge and an untracked file of the same name was added to
the working copy, then without that extra condition the untracked file
will be erroneously deleted. This changes <expression> to "renamed_stage
== 2 || !was_tracked(ren1_src)".
The second additional condition is relevant in two cases.
The first case the second condition can occur is when a file is deleted
and a completely different file is added with the same name. To my
knowledge, merge-recursive has no mechanism for detecting deleted-and-
replaced-by-different-file cases, so I am simply punting on this
possibility.
The second case for the second condition to occur is when there is a
rename/rename/add-source conflict. That is, when the original file was
renamed on both sides of history AND the original filename is being
re-used by some unrelated (but tracked) content. This case also presents
some additional difficulties for us since we cannot currently detect these
rename/rename/add-source conflicts; as long as the rename detection logic
"optimizes" by ignoring filenames that are present at both ends of the
diff, these conflicts will go unnoticed. However, rename/rename conflicts
are handled by an entirely separate codepath not being discussed here, so
this case is not relevant for the line of code under consideration.
In summary:
Change <expression> from "o->call_depth || renamed_stage == 2" to
"renamed_stage == 2 || !was_tracked(ren1_src)", in order to remove
unnecessary code and avoid deleting untracked files.

Add testcases that cover three failures with current git merge, all
involving renaming one file on both sides of history:
Case 1:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. Adding a new file on one of those
sides of history whose name happens to match the rename source should not
cause the merge to suddenly succeed.
Case 2:
If a single file is renamed on both sides of history but renamed
identically, there should not be a conflict. This works fine. However,
if one of those sides also added a new file that happened to match the
rename source, then that file should be left alone. Currently, the
rename/rename conflict handling causes that new file to become untracked.
Case 3:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. This works currently. However,
if those renames also involve rename/add conflicts (i.e. there are new
files on one side of history that match the destination of the rename of
the other side of history), then the resulting conflict should be recorded
in the index, showing that there were multiple files with a given filename.

Add testcases that cover a variety of merge issues with files being
renamed and modified on different sides of history, when there are
directories possibly conflicting with the rename location.
Case 1:
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a non-conflicting
way but is renamed to the location of the new directory.
Case 2:
[Same as case 1, but there is also a content conflict. In detail:]
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a conflicting way
and it is renamed to the location of the new directory.
Case 3:
[Similar to case 1, but the "conflicting" directory is the directory
where the file original resided. In detail:]
On one side of history, a file is modified. On the other side of history,
the file is modified in a non-conflicting way, but the directory it was
under is removed and the file is renamed to the location of the directory
it used to reside in (i.e. 'sub/file' gets renamed to 'sub'). This is
flagged as a directory/rename conflict, but should be able to be resolved
since the directory can be cleanly removed by the merge.
One branch renames a file and makes a file where the directory the renamed
file used to be in, and the other branch updates the file in
place. Merging them should resolve it cleanly as long as the content level
change on the branches do not overlap and rename is detected, or should
leave conflict without losing information.

The following sequence of commands reveals an issue with error
reporting of relative paths:
$ mkdir sub
$ cd sub
$ git ls-files --error-unmatch ../bbbbb
error: pathspec 'b' did not match any file(s) known to git.
$ git commit --error-unmatch ../bbbbb
error: pathspec 'b' did not match any file(s) known to git.
This bug is visible only if the normalized path (i.e., the relative
path from the repository root) is longer than the prefix.
Otherwise, the code skips over the normalized path and reads from
an unused memory location which still contains a leftover of the
original command line argument.
So instead, use the existing facilities to deal with relative paths
correctly.
Also fix inconsistency between "checkout" and "commit", e.g.
$ cd Documentation
$ git checkout nosuch.txt
error: pathspec 'Documentation/nosuch.txt' did not match...
$ git commit nosuch.txt

by propagating the prefix down the codepath that reports the error.

Git currently reports loose objects as 'corrupt' if they've been
deflated using a window size less than 32Kb, because the
experimental_loose_object() function doesn't recognise the header
byte as a zlib header. This patch makes the function tolerant of
all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice
it's accuracy in distingushing the standard loose-object format
from the experimental (now abandoned) format.
On memory constrained systems zlib may use a much smaller window
size - working on Agit, I found that Android uses a 4KB window;
giving a header byte of 0x48, not 0x78. Consequently all loose
objects generated appear 'corrupt', which is why Agit is a read-only
Git client at this time - I don't want my client to generate Git
repos that other clients treat as broken :(
This patch makes Git tolerant of different deflate settings - it
might appear that it changes experimental_loose_object() to the point
where it could incorrectly identify the experimental format as the
standard one, but the two criteria (bitmask & checksum) can only
give a false result for an experimental object where both of the
following are true:
1) object size is exactly 8 bytes when uncompressed (bitmask)
2) [single-byte in-pack git type&size header] * 256
+ [1st byte of the following zlib header] % 31 = 0 (checksum)
As it happens, for all possible combinations of valid object type
(1-4) and window bits (0-7), the only time when the checksum will be
divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which,
due the fields all Commit objects must contain, could never be as
small as 8 bytes in size.
Given this, the combination of the two criteria (bitmask & checksum)
always correctly determines the buffer format, and is more tolerant
than the previous version.
The alternative to this patch is simply removing support for the
experimental format, which I am also totally cool with.

The documentation declares following identity format:
(<name> SP)? LT <email> GT
where name is any string without LF and LT characters.
But fast-import just accepts any string up to first GT
instead of checking the whole format, and moreover just
writes it as is to the commit object.
git-fsck checks for [^<\n]* <[^<>\n]*> format. Note that the
space is mandatory. And the space quirk is already handled via
extending the string to the left when needed.
Modify fast-import input identity format to a slightly stricter
one - deny LF, LT and GT in both <name> and <email>. And check
for it.
This is stricter then git-fsck as fsck accepts "Name> <email>"
currently, but soon fsck check will be adjusted likewise.

fast-import format declares 'committer_name SP' to be optional in
'committer_name SP LT email GT'. But for a (commit) object SP is
obligatory while zero length committer_name is ok. git-fsck checks
that SP is present, so fast-import must prepend it if the name SP
part is omitted. It doesn't do so and thus for "LT email GT" ident
it writes a bad object.
Name cannot contain LT or GT, ident always comes after SP in fast-import.
So if ident starts with LT reuse the SP as if a valid 'SP LT email GT'
ident was passed.
This fixes a ident parsing bug for a well-formed fast-import input.
Though the parsing is still loose and can accept a ill-formed input.

Documentation/git-fast-import.txt says that git-fast-import is strict
about it's input format. But committer/author field parsing is a bit
loose. Invalid values can be unnoticed and written out to the commit,
either with format-conforming input or with non-format-conforming one.
Add one passing and one failing test for empty/absent committer name
with well-formed input. And a failed test with unnoticed ill-formed
input.

The call to test_expect_success is nested inside a function, whose
arguments the test code wants to access. But it is not specified that any
unexpanded $1, $2, $3, etc in the test code will access the surrounding
function's arguments. Rather, they will access the arguments of the
function that happens to eval the test code.
In this case, the reference is intended to supply '-m message' to a call of
'git commit --squash'. Remove it because -m is optional and the test case
does not check for it. There are tests in t7500 that check combinations of
--squash and -m.

* js/ls-tree-error:
Ensure git ls-tree exits with a non-zero exit code if read_tree_recursive fails.
Add a test to check that git ls-tree sets non-zero exit code on error.
In olden times, tests would quietly exit the script when they failed
at an inconvenient moment, which was a little disconcerting.
Therefore v0.99.5~24^2~4 (Trapping exit in tests, using return for
errors, 2005-08-10) switched to an idiom of using "return" instead,
wrapping evaluation of test code in a function to make that safe:
test_run_ () {
eval >&3 2>&4 "$1"
eval_ret="$?"
return 0
}
Years later, the implementation of test_when_finished (v1.7.1.1~95,
2010-05-02) and v1.7.2-rc2~1^2~13 (test-lib: output a newline before
"ok" under a TAP harness, 2010-06-24) took advantage of test_run_ as a
place to put code shared by all test assertion functions, without
paying attention to the function's former purpose:
test_run_ () {
...
eval >&3 2>&4 "$1"
eval_ret=$?
if should run cleanup
then
eval >&3 2>&4 "$test_cleanup"
fi
if TAP format requires a newline here
then
echo
fi
return 0
}
That means cleanup commands and the newline to put TAP output at
column 0 are skipped when tests use "return" to fail early. Fix it by
introducing a test_eval_ function to catch the "return", with a
comment explaining the new function's purpose for the next person who
might touch this code.

As v0.99.5~24^2~4 (Trapping exit in tests, using return for errors,
2005-08-10) explains, callers to test_run_ (such as test_expect_code)
used to check the result from eval and the return value separately so
tests that fail early could be distinguished from tests that completed
normally with successful (nonzero) status. Eventually tests that
succeed with nonzero status were phased out (see v1.7.4-rc0~65^2~19,
2010-10-03 and especially v1.5.5-rc0~271, 2008-02-01) but the weird
two-return-value calling convention lives on.
Let's get rid of it. The new rule: test_run_ succeeds (returns 0)
if and only if the test succeeded.

Introduce a new "git cherry-pick --continue" command which uses the
information in ".git/sequencer" to continue a cherry-pick that stopped
because of a conflict or other error. It works by dropping the first
instruction from .git/sequencer/todo and performing the remaining
cherry-picks listed there, with options (think "-s" and "-X") from the
initial command listed in ".git/sequencer/opts".
So now you can do:
$ git cherry-pick -Xpatience foo..bar
... description conflict in commit moo ...
$ git cherry-pick --continue
error: 'cherry-pick' is not possible because you have unmerged files.
fatal: failed to resume cherry-pick
$ echo resolved >conflictingfile
$ git add conflictingfile && git commit
$ git cherry-pick --continue; # resumes with the commit after "moo"
During the "git commit" stage, CHERRY_PICK_HEAD will aid by providing
the commit message from the conflicting "moo" commit. Note that the
cherry-pick mechanism has no control at this stage, so the user is
free to violate anything that was specified during the first
cherry-pick invocation. For example, if "-x" was specified during the
first cherry-pick invocation, the user is free to edit out the message
during commit time. Note that the "--signoff" option specified at
cherry-pick invocation time is not reflected in the commit message
provided by CHERRY_PICK_HEAD; the user must take care to add
"--signoff" during the "git commit" invocation.

Protect the user from forgetting about a pending sequencer operation
by immediately erroring out when an existing cherry-pick or revert
operation is in progress like:
$ git cherry-pick foo
... conflict ...
$ git cherry-pick moo
error: .git/sequencer already exists
hint: A cherry-pick or revert is in progress
hint: Use --reset to forget about it
fatal: cherry-pick failed
A naive version of this would break the following established ways of
working:
$ git cherry-pick foo
... conflict ...
$ git reset --hard # I actually meant "moo" when I said "foo"
$ git cherry-pick moo
$ git cherry-pick foo
... conflict ...
$ git commit # commit the resolution
$ git cherry-pick moo # New operation

state" and "revert: Remove sequencer state when no commits are

When cherry-pick or revert is called on a list of commits, and a
conflict encountered somewhere in the middle, the data in
".git/sequencer" is required to continue the operation. However, when
a conflict is encountered in the very last commit, the user will have
to "continue" after resolving the conflict and committing just so that
the sequencer state is removed. This is how the current "rebase -i"
script works as well.
$ git cherry-pick foo..bar
... conflict encountered while picking "bar" ...
$ echo "resolved" >problematicfile
$ git add problematicfile
$ git commit
$ git cherry-pick --continue # This would be a no-op
Change this so that the sequencer state is cleared when a conflict is
encountered in the last commit. Incidentally, this patch makes sure
that some existing tests don't break when features like "--reset" and
"--continue" are implemented later in the series.
A better way to implement this feature is to get the last "git commit"
to remove the sequencer state. However, that requires tighter
coupling between "git commit" and the sequencer, a goal that can be
pursued once the sequencer is made more general.

Years of muscle memory have trained users to use "git reset --hard" to
remove the branch state after any sort operation. Make it also remove
the sequencer state to facilitate this established workflow:
$ git cherry-pick foo..bar
... conflict encountered ...
$ git reset --hard # Oops, I didn't mean that
$ git cherry-pick quux..bar
... cherry-pick succeeded ...
Guard against accidental removal of the sequencer state by providing
one level of "undo". In the first "reset" invocation,
".git/sequencer" is moved to ".git/sequencer-old"; it is completely
removed only in the second invocation.

Many pathnames in a fast-import stream need to be quoted. In
particular:
1. Pathnames at the end of an "M" or "D" line need quoting
if they contain a LF or start with double-quote.
2. Pathnames on a "C" or "R" line need quoting as above,
but also if they contain spaces.
For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.
This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.
In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

Normalize the path arguments (relative to the working tree root, if
applicable) before looking up their attributes. This requires passing
the prefix down the call chain.
This fixes two test cases for different reasons:
* "unnormalized paths" is fixed because the .gitattribute-file-seeking
code is not confused into reading the top-level file twice.
* "relative paths" is fixed because the canonical pathnames are passed
to get_check_attr() or get_all_attrs(), allowing them to match the

Take the opportunity to publicly expose the sequencer paths, and a
generic function called "remove_sequencer_state" that various git
programs can use to remove the sequencer state in a uniform manner;
"git reset" uses it later in this series. Introducing this public API

Ever since v1.7.2-rc1~4^2~7 (revert: allow cherry-picking more than
one commit, 2010-06-02), a single invocation of "git cherry-pick" or
"git revert" can perform picks of several individual commits. To
implement features like "--continue" to continue the whole operation,
we will need to store some information about the state and the plan at
the beginning. Introduce a ".git/sequencer/head" file to store this
state, and ".git/sequencer/todo" file to store the plan. The head
file contains the SHA-1 of the HEAD before the start of the operation,
and the todo file contains an instruction sheet whose format is
inspired by the format of the "rebase -i" instruction sheet. As a
result, a typical todo file looks like:
pick 8537f0e submodule add: test failure when url is not configured
pick 4d68932 submodule add: allow relative repository path
pick f22a17e submodule add: clean up duplicated code
pick 59a5775 make copy_ref globally available
Since SHA-1 hex is abbreviated using an find_unique_abbrev(), it is
unambiguous. This does not guarantee that there will be no ambiguity
when more objects are added to the repository.
These two files alone are not enough to implement a "--continue" that
remembers the command-line options specified; later patches in the
series save them too.
These new files are unrelated to the existing .git/CHERRY_PICK_HEAD,
which will still be useful while committing after a conflict
resolution.

$ mkdir /tmp/git-test/real
$ ln -s real /tmp/git-test/link

$ ./t7400-submodule-basic --root=/tmp/git-test/link

not ok - 41 use superproject as upstream when path is relative and no url is set there
The failing test does:
git submodule add ../repo relative &&
...
git submodule sync relative &&
test "$(git config submodule.relative.url)" = "$submodurl/repo"
where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).
Fix this by asking pwd to canonicalize the name of the trash
directory for us.

On modern multi-core processors "make test" is often run in multiple jobs.
If one of them fails the test run does stop, but the concurrently running
tests finish their run. It is rather easy to find out which test failed by
doing a "ls -d t/trash*". But that only works when you don't use the "-i"
option to "make test" because you want to get an overview of all failing
tests. In that case all thrash directories are deleted end and the
information which tests failed is lost.
If one or more tests failed, print a list of them before the test summary:
failed test(s): t1000 t6500
fixed 0

The reset command creates its reflog entry from argv.
However, it does so after having run parse_options, which
means the only thing left in argv is any non-option
arguments. Thus you would end up with confusing reflog
entries like:
$ git reset --hard HEAD^
$ git reset --soft HEAD@{1}
$ git log -2 -g --oneline
8e46cad HEAD@{0}: HEAD@{1}: updating HEAD
1eb9486 HEAD@{1}: HEAD^: updating HEAD
However, we must also consider that some scripts may set
GIT_REFLOG_ACTION before calling reset, and we need to show
their reflog action (with our text appended). For example:
rebase -i (squash): updating HEAD
On top of that, we also set the ORIG_HEAD reflog action
(even though it doesn't generally exist). In that case, the
reset argument is somewhat meaningless, as it has nothing to
do with what's in ORIG_HEAD.
This patch changes the reset reflog code to show:
$GIT_REFLOG_ACTION: updating {HEAD,ORIG_HEAD}
as before, but only if GIT_REFLOG_ACTION is set. Otherwise,
show:
reset: moving to $rev
for HEAD, and:
reset: updating ORIG_HEAD
for ORIG_HEAD (this is still somewhat superfluous, since we
are in the ORIG_HEAD reflog, obviously, but at least we now
mention which command was used to update it).
While we're at it, we can clean up the code a bit:
- Use strbufs to make the message.
- Use the "rev" parameter instead of showing all options.
This makes more sense, since it is the only thing
impacting the writing of the ref.

Currently the helper must somehow guess how many import statements to
read before it starts outputting its fast-export stream. This is
because the remote helper infrastructure runs fast-import only once,
so the helper is forced to output one stream for all import commands
it will receive. The only reason this worked in the past was because
only one ref was imported at a time.

If the new --done command line flag was passed on the command line

make the 'done' command mandatory. So "git fast-import --done"'s
input format will be prefix-free, making errors easier to detect when
they show up as early termination at some convenient time of the
upstream of a pipe writing to fast-import.
Another possible application of the 'done' command would to be allow a
fast-import stream that is only a small part of a larger encapsulating
stream to be easily parsed, leaving the file offset after the "done\n"
so the other application can pick up from there. This patch does not
teach fast-import to do that --- fast-import still uses buffered input

not local refs. The mapped local refs are included via the
peer_ref pointer. So when we add an argument to our
fast-export command line, we must be sure to use the local
peer_ref name (and if there is no local name, it is because
we are not actually sending that ref, or we may not even
have the ref at all).

Upon receiving an "import" command, the testgit remote
helper would ignore the ref asked for by git and generate a
fast-export stream based on HEAD. Instead, we should
actually give git the ref it asked for.
This requires adding a new parameter to the export_repo
method in the remote-helpers python library, which may be
used by code outside of git.git. We use a default parameter
so that callers without the new parameter will get the same
behavior as before.

These are all things one might expect to work in a helper
that is capable of handling multiple branches (which our
testgit helper in theory should be able to do, as it is
backed by git). All of these bugs are specific to the
import/export codepaths, so they don't affect helpers like
git-remote-curl that use fetch/push commands.
The first and fourth tests are about fetching and pushing
new refs, and demonstrate bugs in the git_remote_helpers
library (so they would be most likely to impact helpers for
other VCSs which import/export git).
The second test is about importing multiple refs; it
demonstrates a bug in git-remote-testgit, which is mostly
for exercising the test code. Therefore it probably doesn't
affect anyone in practice.
The third test demonstrates a bug in git's side of the
helper code when the upstream has added refs that we do not
have locally. This could impact git users who use remote
helpers to access foreign VCSs.
All of those bugs have fixes later in this series.
The fifth test is the most complex, and does not have a fix
in this series. It tests pushing a ref via the export
mechanism to a new name on the remote side (i.e.,
"git push $remote old:new").
The problem is that we push all of the work of generating
the export stream onto fast-export, but we have no way of
communicating to fast-export that this name mapping is
happening. So we tell fast-export to generate a stream with
the commits for "old", but we can't tell it to label them
all as "new".

The user-supplied command spawned by 'submodule foreach' loses its
connection to the original standard input. Instead, it is connected to the
output of a pipe within the git-submodule script. The user-supplied
command supplied to 'submodule foreach' is spawned within a while loop
which is being piped into. Due to the way shells implement piping output
to a while loop, a subshell is created with its standard input attached to
the output of the pipe. This results in all of the commands executed
within the while loop to have their stdins modified in the same way,
including the user-supplied command.
This can cause a problem if the command requires reading from stdin or if
it changes its behavior based on whether stdin is a tty or not. For
example, this problem was noticed when trying to execute the following:
git submodule foreach git shortlog --since=two.weeks.ago
which printed a message about entering the first submodule and produced no
further output and exited with a status of zero. In this case, shortlog
detected that it was not connected to a tty, and since no revision was
supplied as an argument, it attempted to read the list of revisions from
standard input. Instead, it slurped up the list of submodules that was
being piped to the enclosing while loop and caused that loop to end early
without processing the remaining submodules.
Work around this behavior by saving the original standard input file
descriptor before the while loop, and restoring it when spawning the
user-supplied command.
This fixes the tests in t7407.

The --include-untracked option acts like the normal "git stash save" but
also adds all untracked files in the working directory to the stash and then
calls "git clean --force --quiet" to restore the working directory to a
pristine state.
This is useful for projects that need to run release scripts. With this
option, the release scripts can be from the main working directory so one
does not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:
$ git tag release-1.0
$ git stash --include-untracked
$ make release
$ git clean -f
$ git stash pop
"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to
be very clean or might let a release succeed that should actually fail (due
to a new source file being created that hasn't been committed yet).

Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.
In many cases, this is a minor convenience over something
like:
git clone git://...
git config core.whatever true
But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.
It also provides a mechanism for passing information to remote
helpers during a clone; the helpers may read the git config
to influence how they operate.

The error handling for git_config is somewhat confusing. We
collect errors from running git_config_from_file on the
various config files and carefully pass them back up. But
the two odd things are:
1. We actually die on most errors in git_config_from_file.
In fact, the only error we actually pass back up is if
fopen() fails on the file.
2. Most callers of git_config do not check the error
return at all, but will continue if git_config reports
an error.
When the code for "git -c core.foo=bar" was added, it
dutifully passed errors up the call stack, only for them to
be eventually ignored. This makes it inconsistent with the
file-parsing code, which will die when it sees malformed
config. And it's somewhat unsafe, because it means an error
in parsing a typo like:
git -c clean.requireforce=ture clean
will continue the command, ignoring the config the user
tried to give.

Consider this graph:

F (topic2)
and the following three commands:
1. git rebase -i -p A
2. git rebase -i -p --onto F A
3. git rebase -i -p B
Currently, (1) and (2) will pick B, D, C, and E onto A and F,
respectively. However, (3) will only pick D and E onto B, but not C,
which is inconsistent with (1) and (2). As a result, we cannot modify C
during the interactive-rebase.
The current behavior also creates a bug if we do:
4. git rebase -i -p C
In (4), E is never picked. And since interactive-rebase resets "HEAD"
to "onto" before picking any commits, D and E are lost after the
interactive-rebase.
This patch fixes the inconsistency and bug by ensuring that all children
of upstream are always picked. This essentially reverts the commit:
d80d6bc146
When compiling the todo list, commits reachable from "upstream" should
never be skipped under any conditions. Otherwise, we lose the ability
to modify them like (3), and create a bug like (4).
Two of the tests contain a scenario like (3). Since the new behavior
added more commits for picking, these tests need to be updated to
account for the additional pick lines. A new test has also been added

"git submodule update" stops at the first error and gives control
back to the user. Only after the user fixes the problematic
submodule and runs "git submodule update" again, the second error
is found. And the user needs to repeat until all the problems are
found and fixed one by one. This is tedious.
Instead, the command can remember which submodules it had trouble with,
continue updating the ones it can, and report which ones had errors at
the end. The user can run "git submodule update", find all the ones that
need minor fixing (e.g. working tree was dirty) to fix them in a single
pass. Then another "git submodule update" can be run to update all.
Note that the problematic submodules are skipped only when they are to
be integrated with a safer value of submodule.<name>.update option,
namely "checkout". Fixing a failure in a submodule that uses "rebase" or
"merge" may need an involved conflict resolution by the user, and
leaving too many submodules in states that need resolution would not
reduce the mental burden on the user.

v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are

intuitive for webmasters by checking whether the ctags/<label> under
a project's .git dir contains a number (representing the strength of
association to <label>) before treating it as one.
With that change, after putting '$feature{'ctags'}{'default'} = [1];'
in your $GITWEB_CONFIG, you could do
echo Linux >.git/ctags/linux

with the Linux tag, instead of the previous behavior of writing an
error page embedded in the projects list that triggers error messages
from Chromium and Firefox about malformed XML.
Unfortunately the pattern (\d+) used to match numbers is too loose,
and the "XML declaration allowed only at the start of the document"
error can still be experienced if you write "Linux-2.6" in place of
"Linux" in the example above. Fix it by tightening the pattern to

In most cases, fetching the remote HEAD explicitly is
unnecessary. It's just a symref pointing to a branch which
we are already fetching, so we will already ask for its sha1.
However, if the remote has a detached HEAD, things are less
certain. We do not ask for HEAD's sha1, but we do try to
write it into a local detached HEAD. In most cases this is
fine, as the remote HEAD is pointing to some part of the
history graph that we will fetch via the refs.
But if the remote HEAD points to an "orphan" commit (one
which was is not an ancestor of any refs), then we will not
have the object, and update_ref will complain when we try to
write the detached HEAD, aborting the whole clone.
This patch makes clone always explicitly ask the remote for
the sha1 of its HEAD commit. In the non-detached case, this
is a no-op, as we were going to ask for that sha1 anyway. In
the regular detached case, this will add an extra "want" to
the protocol negotiation, but will not change the history
that gets sent. And in the detached orphan case, we will
fetch the orphaned history so that we can write it into our
local detached HEAD.

When create a new branch, we fed "refs/heads/<proposed name>" as a string
to get_sha1() and expected it to fail when a branch already exists.
The right way to check if a ref exists is to check with resolve_ref().
A naïve solution that might appear attractive but does not work is to
forbid slashes in get_describe_name() but that will not work. A describe
name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part
comes from a original tag name used in the repository the user ran the
describe command. A sick user could have a confusing hierarchical tag
whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar")
to generate a describe name "refs/heads/foobar-6-g02ac983", and we should

Commit 431d6e7b (grep: enable threading for context line printing)
split the printing of the "--\n" mark between results from different
files out into two places: show_line() in grep.c for the non-threaded
case and work_done() in builtin/grep.c for the threaded case. Commit
55f638bd (grep: Colorize filename, line number, and separator) updated
the former, but not the latter, so the separators between files are
not colored if threads are used.
This patch merges the two. In the threaded case, hunk marks are now
printed by show_line() for every file, including the first one, and the
very first mark is simply skipped in work_done(). This ensures that the
output is properly colored and works just as well.

The guess_remote_head function tries to figure out where a
remote's HEAD is pointing by comparing the sha1 of the
remote's HEAD with the sha1 of various refs found on the
remote. However, we were too liberal in matching refs, and
would match tags or remote tracking branches, even though
these things could not possibly be referenced by the HEAD
symbolic ref (since git will detach when checking them out).
As a result, a clone of a remote repository with a detached
HEAD might write "refs/tags/*" into our local HEAD, which is
bogus. The resulting HEAD should be detached.
The other related code path is remote.c's get_head_names()
(which is used for, among other things, "set-head -a"). This was
not affected, however, as that function feeds only refs from
refs/heads to guess_remote_head.

We didn't test this setup at all, and doing so reveals a few
bugs:
1. Cloning a repository with an orphaned detached HEAD
(i.e., one that points to history that is not
referenced by any ref) will fail.
2. Cloning a repository with a detached HEAD that points
to a tag will cause us to write a bogus "refs/tags/..."
ref into the HEAD symbolic ref. We should probably
detach instead.
3. Cloning a repository with a detached HEAD that points
to a branch will cause us to checkout that branch. This
is a known limitation of the git protocol (we have to
guess at HEAD's destination, since the symref contents
aren't shown to us). This test serves to document the
desired behavior, which can only be achieved once the
git protocol learns to share symref information.

Commit 2cfe8a6 (diff --quiet: disable optimization when

If you give a zero-length subject prefix to format-patch

Brian Gernhardt reported that test 'git grep -E -F -G a\\+b' fails on

true on all platforms.
The easiest way to make this test pass is to just update expected
output, but that would make the test pointless. Its real purpose is to
check whether 'git grep -E -F -G' is different from 'git grep -E -G -F'.
To check that, let's change pattern to "a+b*c". This should return
different match for -G, -F and -E.
I also made two small tweaks to the tests. First, I added path "ab" to
all calls to future-proof tests. Second, I updated last two tests to
better show that 'git grep -P -E' is different from 'git grep -E -P'.

When we finish a rebase, our detached HEAD is at the final
result. We update the original branch ref with this result,
and then point the HEAD symbolic ref at the updated branch.
We write a reflog for the branch update, but not for the
update of HEAD.
Because we're already at the final result on the detached
HEAD, moving to the branch actually doesn't change our
commit sha1 at all. So in that sense, a reflog entry would
be pointless.
However, humans do read reflogs, and an entry saying "rebase

In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it. But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.
This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant. This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

Without the "-k" option, mailinfo will convert a folded
subject header like:
Subject: this is a
subject that doesn't
fit on one line
into a single line. With "-k", however, we assumed that
these newlines were significant and represented something
that the sending side would want us to preserve.
For messages created by format-patch, this assumption was
broken by a1f6baa (format-patch: wrap long header lines,
2011-02-23). For messages sent by arbitrary MUAs, this was
probably never a good assumption to make, as they may have
been folding subjects in accordance with rfc822's line
length recommendations all along.
This patch now joins folded lines with a single whitespace
character. This treats header folding purely as a syntactic
feature of the transport mechanism, not as something that
format-patch is trying to tell us about the original
subject.

Commit a1f6baa (format-patch: wrap long header lines,
2011-02-23) changed format-patch's behavior with respect to
long header lines, but made no accompanying changes to the
receiving side. It was thought that "git am" would handle
these folded subjects fine, but there is a regression when
using "am -k".
Let's add a test documenting this. While we're at it, let's
give more complete test coverage to document what should be
happening in each case. We test three types of subjects:
a short one, one long enough to require wrapping, and a
multiline subject. For each, we test these three
combinations:
format-patch | am
format-patch -k | am
format-patch -k | am -k
We don't bother testing "format-patch | am -k", which is
nonsense (you will be adding in [PATCH] cruft to each
subject).
This reveals the regression above (long subjects have
linebreaks introduced via "format-patch -k | am -k"),
as well as an existing non-optimal behavior (multiline
subjects are not preserved using "-k").

Commit 13fc2c1 (remote: disallow some nonsensical option
combinations, 2011-03-30) made it impossible to use "remote
add -t foo --mirror". The argument was that specifying
specific branches is useless because:
1. Push mirrors do not want a refspec at all.
2. The point of fetch mirroring is to use a broad refspec
like "refs/*", but using "-t" overrides that.
Point (1) is valid; "-t" with push mirrors is useless. But
point (2) ignored another side effect of using --mirror: it
fetches the refs directly into the refs/ namespace as they
are found upstream, instead of placing them in a
separate-remote layout.
So 13fc2c1 was overly constrictive, and disallowed
reasonable specific-branch mirroring, like:
git remote add -t heads/foo -t heads/bar --mirror=fetch
which makes the local "foo" and "bar" branches direct
mirrors of the remote, but does not fetch anything else.
This patch restores the original behavior, but only for
fetch mirrors.

Handle input in Subversion's dumpfile format, version 3. This is the
format produced by "svnrdump dump" and "svnadmin dump --deltas", and
the main difference between v3 dumpfiles and the dumpfiles already
handled is that these can include nodes whose properties and text are
expressed relative to some other node.
To handle such nodes, we find which node the text and properties are
based on, handle its property changes, use the cat-blob command to
request the basis blob from the fast-import backend, use the
svndiff0_apply() helper to apply the text delta on the fly, writing
output to a temporary file, and then measure that postimage file's
length and write its content to the fast-import stream.
The temporary postimage file is shared between delta-using nodes to
avoid some file system overhead.
The svn-fe interface needs to be more complicated to accomodate the
backward flow of information from the fast-import backend to svn-fe.
The backflow fd is not needed when parsing streams without deltas,
though, so existing scripts using svn-fe on v2 dumps should
continue to work.

The handle_options() function advances the base of the argument array and
returns the number of arguments it used. The caller in handle_alias()
wants to reallocate the argv array it passes to this function, and
attempts to do so by subtracting the returned value to compensate for the
change handle_options() makes to the new_argv.
But handle_options() did not correctly count when "-c <config=value>" is
given, causing a wrong pointer to be passed to realloc().
Fix it by saving the original argv at the beginning of handle_options(),
and return the difference between the final value of argv, which will
relieve the places that move the array pointer from the additional burden
of keeping track of "handled" counter.

Previously we parsed GIT_CONFIG_PARAMETERS lazily into a
linked list, and then checked that list during future

that the environment variable could change during our run
(e.g., because we parse more "-c" as part of an alias).
Instead, let's just re-parse the environment variable each

As a bonus, we can ditch all of the linked list storage code

NULs caused us to show incorrect diffs, with lines truncated

(embedded NULs could interfere with "-z" output, possibly
defeating policy hooks which parse diff output).
Instead, we consider a combined diff to be binary if any of
the input blobs is binary. To show a binary combined diff,
we indicate "Binary blobs differ"; the "index" meta line

A naive method of treating BEGIN/END blocks with a brace on the second
line as diff/grep funcname context involves also matching unrelated
lines that consist of all-caps letters:
sub foo {
print <<'EOF'
text goes here
...
EOF
... rest of foo ...
}
That's not so great, because it means that "git diff" and "git grep
--show-function" would write "=EOF" or "@@ EOF" as context instead of
a more useful reminder like "@@ sub foo {".
To avoid this, tighten the pattern to only match the special block
names that perl accepts (namely BEGIN, END, INIT, CHECK, UNITCHECK,
AUTOLOAD, and DESTROY). The list is taken from perl's toke.c.

The userdiff funcname mechanism has no concept of nested scopes ---
instead, "git diff" and "git grep --show-function" simply label the
diff header with the most recent matching line. Unfortunately that
means text following a subroutine in a POD section:
=head1 DESCRIPTION
You might use this facility like so:
sub example {
foo;
}
Now, having said that, let's say more about the facility.
Blah blah blah ... etc etc.
gets the subroutine name instead of the POD header in its diff/grep
funcname header, making it harder to get oriented when reading a
diff without enough context.
The fix is simple: anchor the funcname syntax to the left margin so
nested subroutines and packages like this won't get picked up. (The
builtin C++ funcname pattern already does the same thing.) This means
the userdiff driver will misparse the idiom
{
my $static;
sub foo {
... use $static ...
}
}
but I think that's worth it; we can revisit this later if the userdiff
mechanism learns to keep track of the beginning and end of nested
scopes.

Introduce a test_expect_funcname function to make a diff and apply a
regexp anchored on the left to the function name it writes, avoiding
some repetition.
Omit the space after >, <<, and < operators for consistency with
other scripts. Quote the <<here document delimiter and $ signs in
quotes so readers don't have to worry about the effect of shell
metacharacters.
Remove some unnecessary blank lines.
Run "git diff" as a separate command instead of as upstream of a pipe
that checks its output, so the exit status can be tested. In
particular, this way if "git diff" starts segfaulting the test harness
will notice.
Allow "error:" as a synonym for "fatal:" when checking error messages,
since whether a command uses die() or "return error()" is a small
implementation detail.
Anchor some more regexes on the right.
None of the above is very important on its own; the point is just to
make the script a little easier to read and the code less scary to
modify.

Introduce a "test_config" function to set a configuration variable
for use by a single test (automatically unsetting it when the
assertion finishes). If this function is used consistently, the
configuration used in a test_expect_success block can be read at the
beginning of that block instead of requiring reading all the tests
that come before. So it becomes a little easier to add new tests or
rearrange existing ones without fear of breaking configuration.
In particular, the test of alternation in xfuncname patterns also
checks that xfuncname takes precedence over funcname variable as a
sort of side-effect, since the latter leaks in from previous tests.
In the new syntax, the test has to say explicitly what variables it is
using, making the test clearer and a future regression in coverage
from carelessly editing the script less likely.

Most, but not all, tests in this script rely on attributes declaring
that files with a .java extension should use the "java" driver:
*.java diff=java
Split out a "set up" test to put such a .gitattributes in place after
the tests that do not want it have run, to make it more likely that
individual tests other than this setup test can be safely modified,
rearranged, or skipped. Presumably this setup code will learn to
request other drivers for other extensions in the same place when the
test suite learns to exercise other diff drivers.
Similarly, make sure that early test assertions that do not use these
default attributes set up .gitattributes appropriately for themselves,
so tests that run before can be modified with less risk of breaking
something.

With diff.suppress-blank-empty=true, "git diff --word-diff" would
output data that had been read from uninitialized heap memory.
The problem was that fn_out_consume did not account for the
possibility of a line with length 1, i.e., the empty context line
that diff.suppress-blank-empty=true converts from " \n" to "\n".
Since it assumed there would always be a prefix character (the space),
it decremented "len" unconditionally, thus passing len=0 to emit_line,
which would then blindly call emit_line_0 with len=-1 which would
pass that value on to fwrite as SIZE_MAX. Boom.

As the band-aid to merge-recursive seems to regress complex merges in an
unpleasant way. The merge-recursive implementation needs to be rewritten
in such a way that it resolves renames and D/F conflicts entirely in-core
and not to touch working tree at all while doing so. But in the meantime,
this reverts commit ac9666f84 that merged the topic in its entirety.
Teach the command to read object names to remove from the standard
input, in addition to the object names given from the command line.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
Depending on the application, it is not necessarily an error for an object
to lack a note, especially if the only thing the caller wants to make sure
is that notes are cleared for an object. By passing this option from the
command line, the "git notes remove" command considers it a success if the
object did not have any note to begin with.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.
Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.
Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.

The "git ls-remote" uses its exit status to indicate if it successfully
talked with the remote repository. A new option "--exit-code" makes the
command exit with status "2" when there is no refs to be listed, even when
the command successfully talked with the remote repository.
This way, the caller can tell if we failed to contact the remote, or the
remote did not have what we wanted to see. Of course, you can inspect the
output from the command, which has been and will continue to be a valid
way to check the same thing.

Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g

Commands like "git status", "git diff" and "git fetch" would fail when the
.gitmodules file contained merge conflicts because the config parser would
call die() when hitting the conflict markers:
"fatal: bad config file line <n> in <path>/.gitmodules"
While this behavior was on the safe side, it is really unhelpful to the
user to have commands like status and diff fail, as these are needed to
find out what's going on. And the error message is only mildly helpful,
as it points to the right file but doesn't mention that it is unmerged.
Users of git gui were not shown any conflicts at all when this happened.
Improve the situation by checking if the index records .gitmodules as
unmerged. When that is the case we can't make any assumptions about the
configuration to be found there after the merge conflict is resolved by
the user, so assume that all recursion is disabled unless .git/config or
the global config say otherwise.
As soon as the merge conflict is resolved and the .gitmodules file has
been staged subsequent commands again honor any configuration done there.

When adding a new content to the repository, we have always slurped
the blob in its entirety in-core first, and computed the object name
and compressed it into a loose object file. Handling large binary
files (e.g. video and audio asset for games) has been problematic
because of this design.
At the middle level of "git add" callchain is an internal API
index_fd() that takes an open file descriptor to read from the
working tree file being added with its size. Teach it to call out to
fast-import when adding a large blob.
The write-out codepath in entry.c::write_entry() should be taught to
stream, instead of reading everything in core. This should not be so
hard to implement, especially if we limit ourselves only to loose
object files and non-delta representation in packfiles.
