e9d4f7405b branch.c: use the parsed branch name
When setting up tracking info, branch.c uses the given branch specifier
("name"). Use the parsed name ("ref.buf") instead so that

git branch --set-upstream @{-1} foo

sets up tracking info for the previous branch rather than for a branch
named "@{-1}".

2e6c012e10 setup_pager: set GIT_PAGER_IN_USE
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.

8d68a6d593 t7006: use test_config helpers
In some cases, this is just making the test script a little

d960c47a88 test-lib: add helper functions for config
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".

3beb4fc461 doc/fast-import: document feature import-marks-if-exists
fast-import command-line option --import-marks-if-exists was introduced
in commit dded4f1 (fast-import: Introduce --import-marks-if-exists, 2011-01-15)

--import-marks option can be set via a "feature" command in a fast-import
stream and --import-marks-if-exists had support for such specification
from the very beginning too due to some shared codebase. Though the
documentation for this feature wasn't written in dded4f1.

Add the documentation for "feature import-marks-if-exists=<file>". Also add
a minimalistic test for it.

127f045222 revert: plug memory leak in "cherry-pick root commit" codepath
The empty tree passed as common ancestor to merge_trees() when
cherry-picking a parentless commit is allocated on the heap and never
freed.  Leaking such a small one-time allocation is not a very big
problem, but now that "git cherry-pick" can cherry-pick multiple
commits it can start to add up.

Avoid the leak by storing the fake tree exactly once in the BSS
section (i.e., use a static).  While at it, let's add a test to make
sure cherry-picking multiple parentless commits continues to work.

8fb3ad76b1 fast-import: prevent producing bad delta
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.

9a0edb79f2 fast-import: add a test for tree delta base corruption
fast-import is able to write imported tree objects in delta format.
It holds a tree structure in memory where each tree entry may have
a delta base sha1 assigned. When delta base data is needed it is
reconstructed from this in-memory structure. Though sometimes the
delta base data doesn't match the delta base sha1 so wrong or even
corrupt pack is produced.

Add a small test that produces a corrupt pack. It uses just tree
copy and file modification commands aside from the very basic commit
and blob commands.

814f7d902b t3030: fix accidental success in symlink rename
In this test, we have merge two branches. On one branch, we
renamed "a" to "e". On the other, we renamed "a" to "e" and
then added a symlink pointing at "a" pointing to "e".

The results for the test indicate that the merge should
succeed, but also that "a" should no longer exist. Since
both sides renamed "a" to the same destination, we will end
up comparing those destinations for content.

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.

434b8525e7 merge-recursive: Consider modifications in rename/rename(2to1) conflicts
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

non-recursive merge and will result in fewer spurious conflicts.

ec61d14963 merge-recursive: Fix modify/delete resolution in the recursive case
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.)

5b448b8530 merge-recursive: When we detect we can skip an update, actually skip it
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().

51931bf08e merge-recursive: Improve handling of rename target vs. directory addition
When dealing with file merging and renames and D/F conflicts and possible
criss-cross merges (how's that for a corner case?), we did not do a
thorough job ensuring the index and working directory had the correct
contents.   Fix the logic in merge_content() to handle this.  Also,
correct some erroneous tests in t6022 that were expecting the wrong number
of unmerged index entries.  These changes fix one of the tests in t6042
(and almost fix another one from t6042 as well).

0a6b87126e merge-recursive: Make dead code for rename/rename(2to1) conflicts undead
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)
code segments to make it handle most cases.  Work is still needed to
handle higher dimensional corner cases such as rename/rename/modify/modify
issues.

531357a4cc merge-recursive: Fix deletion of untracked file in rename/delete conflicts
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.

c6966068fb t6042: Add failing testcases for rename/rename/add-{source,dest} conflicts
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.
Currently, git silently discards one of file versions.

ac6e839241 t6042: Add tests for content issues with modify/rename/directory conflicts
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.

0f64bfa956 ls-files: fix pathspec display on error
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
    error: pathspec 'nosuch.txt' did not match...

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

7f684a2aff Tolerate zlib deflation with window size < 32Kb
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.

So now you can apply patches from GMail with "git am" in three steps:

 1. choose "show original"
 2. tell the browser to "save as" (for example by pressing Ctrl+S)
 3. run "git am" on the saved file

This fixes a regression introduced by v1.6.4-rc0~15^2~2 (git-am

Change it to following. Seek to '<' or '>', check that it is '<' and is
preceeded with ' '. Seek to '<' or '>' and check that it is '>'. So now
"name> <email>" is rejected as "bad name". More strict name check is the

4b4963c0e1 fast-import: check committer name more strictly
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.

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.

4cedb78cb5 fast-import: add input format tests
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.

23ce5c39dc t3900: do not reference numbered arguments from the test script
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.

24c512803d bisect: add support for bisecting bare repositories
This enhances the support for bisecting history in bare repositories.

The "git bisect" command no longer needs to be run inside a repository

repository.

Two tests are included to demonstrate this behaviour.

a7c58f280a test: cope better with use of return for errors
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.

aa0bcf962a test: simplify return value of test_run_
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.

5a5d80f4ca revert: Introduce --continue to continue the operation
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.

21afd08062 revert: Don't implicitly stomp pending sequencer operation
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

However, the previous patches "reset: Make reset remove the sequencer
state" and "revert: Remove sequencer state when no commits are
pending" make sure that this does not happen.

2d27daa91d revert: Remove sequencer state when no commits are pending
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.

95eb88d8ee reset: Make reset remove the sequencer state
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.

6280dfdc3b fast-export: quote paths in output
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

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
  pathname patterns as expected.

"git reset" uses it later in this series.  Introducing this public API

04d3d3cfc4 revert: Save data for continuing after conflict resolution
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.

4e2e6ce450 git-p4: commit time should be most recent p4 change time
When importing a repo, the time on the initial commit had been
just "now".  But this causes problems when trying to share among
git-p4 repos that were created identically, although at different
times.  Instead, use the time in the top-most p4 change as the
time for the git import commit.

dd008b3b11 t7400: fix bogus test failure with symlinked trash
One of the tests in t7400 fails if the trash directory has a
symlink anywhere in its path. E.g.:

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

  $ ./t7400-submodule-basic --root=/tmp/git-test/real
  ...
  # passed all 44 test(s)

  $ ./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.

When using the --quiet flag "git submodule update" and "git submodule add"
didn't behave as the documentation stated. They printed progress output
from the clone, even though they should only print error messages.

Fix that by passing the -q flag to git clone in module_clone() when the

that behavior.

2579e1d293 tests: print failed test numbers at the end of the test run
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
success 7638
failed  3
broken  49
total   7723

This makes it possible to just run the test suite with -i and collect all
failed test scripts at the end for further examination.

d04520e344 reset: give better reflog messages
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.

9504bc9d5a transport-helper: change import semantics
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.

Change the semantics of the import statement such that it matches
that of the push statement. That is, the import statement is followed
by a series of import statements that are terminated by a '\n'.

be56862f19 fast-import: introduce 'done' command
Add a 'done' command that causes fast-import to stop reading from the
stream and exit.

If the new --done command line flag was passed on the command line
(or a "feature done" declaration included at the start of the stream),
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
(stdio).

b4b872994b git_remote_helpers: push all refs during a non-local export
When a remote helper exports to a non-local git repo, the
steps are roughly:

  1. fast-export into a local staging area; the set of
     interesting refs is defined by what is in the fast-export
     stream

  2. git push from the staging area to the non-local repo

In the second step, we should explicitly push all refs, not
just matching ones. This will let us push refs that do not
yet exist in the remote repo.

3ea7d09461 transport-helper: don't feed bogus refs to export push
When we want to push to a remote helper that has the
"export" capability, we collect all of the refs we want to
push and then feed them to fast-export.

However, the list of refs is actually a list of remote refs,
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).

4e51ba238f git-remote-testgit: import non-HEAD refs
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.

c00dd33b1f t5800: document some non-functional parts of remote helpers
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".

4dca1aa650 git-submodule.sh: preserve stdin for the command spawned by foreach
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.

91cd7e4b42 t/t7407: demonstrate that the command called by 'submodule foreach' loses stdin
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.  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 (e.g. git shortlog).  Demonstrate
this flaw.

b586744a86 test: skip clean-up when running under --immediate mode
Some tests try to be too careful about cleaning themselves up and

        test_when_finished "revert the above changes" &&
	the real test
    '

Which is nice to make sure that a potential failure would not have
unexpected interaction with the next test. This however interferes when
"the real test" fails and we want to see what is going on, by running the
test with --immediate mode and descending into its trash directory after
the test stops. The precondition to run the real test and cause it to fail
is all gone after the clean-up procedure defined by test_when_finished is
done.

Update test_run_ which is the workhorse of running a test script
called from test_expect_success and test_expect_failure, so that we do not
run clean-up script defined with test_when_finished when a test that is
expected to succeed fails under the --immediate mode.

ccee60862b submodule sync: do not auto-vivify uninteresting submodule
Earlier 33f072f (submodule sync: Update "submodule.<name>.url" for empty
directories, 2010-10-08) attempted to fix a bug where "git submodule sync"
command does not update the URL if the current superproject does not have
a checkout of the submodule.

However, it did so by unconditionally registering submodule.$name.url to
every submodule in the project, even the ones that the user has never
showed interest in at all by running 'git submodule init' command. This
caused subsequent 'git submodule update' to start cloning/updating submodules
that are not interesting to the user at all.

Update the code so that the URL is updated from the .gitmodules file only
for submodules that already have submodule.$name.url entries, i.e. the
ones the user has showed interested in having a checkout.

787513027a stash: Add --include-untracked option to stash and remove all untracked files
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).

84054f79de clone: accept config options on the command line
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.

1c2c9bee1b config: die on error in command-line config
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.

12bf828348 rebase -i -p: include non-first-parent commits in todo list
Consider this graph:

        D---E    (topic, HEAD)
       /   /
  A---B---C      (master)
   \
    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
for (4).

36bfb0e5f6 tests: link shell libraries into valgrind directory
When we run tests under valgrind, we symlink anything
executable that starts with git-* or test-* into a special
valgrind bin directory, and then make that our
GIT_EXEC_PATH.

However, shell libraries like git-sh-setup do not have the
executable bit marked, and did not get symlinked.  This
means that any test looking for shell libraries in our
exec-path would fail to find them, even though that is a
fine thing to do when testing against a regular git build
(or in a git install, for that matter).

t2300 demonstrated this problem. The fix is to symlink these
shell libraries directly into the valgrind directory.

15ffb7cde4 submodule update: continue when a checkout fails
"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.

2c162b56f3 gitweb: do not misparse nonnumeric content tag files that contain a digit
v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are
handled, 2011-04-29) tried to make gitweb's tag cloud feature more
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

and gitweb would treat that as a request to tag the current repository
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
^\d+$.

c1921c184c clone: always fetch remote HEAD
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.

4d68932004 submodule add: allow relative repository path even when no url is set
Adding a submodule with a relative repository path did only succeed when
the superproject's default remote was set. But when that is unset, the
superproject is its own authoritative upstream, so lets use its working
directory as upstream instead.

This allows users to set up a new superpoject where the submodules urls
are configured relative to the superproject's upstream while its default
remote can be configured later.

3de89c9d42 verify-pack: use index-pack --verify
This finally gets rid of the inefficient verify-pack implementation that
walks objects in the packfile in their object name order and replaces it
with a call to index-pack --verify. As a side effect, it also removes
packed_object_info_detail() API which is rather expensive.

As this changes the way errors are reported (verify-pack used to rely on
the usual runtime error detection routine unpack_entry() to diagnose the
CRC errors in an entry in the *.idx file; index-pack --verify checks the
whole *.idx file in one go), update a test that expected the string "CRC"
to appear in the error message.

c17b229454 checkout -b <name>: correctly detect existing branch
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
be able to use that name to refer to the object whose name is 02ac983.

08303c3636 grep: fix coloring of hunk marks between files
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.

61adfd3097 consider only branches in guess_remote_head
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.

3b368546a0 t: add tests for cloning remotes with detached 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.

af7b41c923 diff_tree: disable QUICK optimization with diff filter
We stop looking for changes early with QUICK, so our diff
queue contains only a subset of the changes. However, we
don't apply diff filters until later; it will appear at that
point as though there are no changes matching our filter,
when in reality we simply didn't keep looking for changes
long enough.

Commit 2cfe8a6 (diff --quiet: disable optimization when
--diff-filter=X is used, 2011-03-16) fixes this in some
cases by disabling the optimization when a filter is
present. However, it only tweaked run_diff_files, missing
the similar case in diff_tree. Thus the fix worked only for
diffing the working tree and index, but not between trees.

Noticed by Yasushi SHOJI.

e7af8e49cd format-patch: make zero-length subject prefixes prettier
If you give a zero-length subject prefix to format-patch
(e.g., "format-patch --subject-prefix="), we will print the
ugly:

  Subject: [ 1/2] your subject here

because we always insert a space between the prefix and
numbering. Requiring the user to provide the space in their
prefix would be more flexible, but would break existing
usage. This patch provides a DWIM and suppresses the space
for zero-length prefixes, under the assumption that nobody
actually wants "[ 1/2]".

d0042abe14 git-grep: Fix problems with recently added tests
Brian Gernhardt reported that test 'git grep -E -F -G a\\+b' fails on
OS X 10.6.7. This is because I assumed \+ is part of BRE, which isn't
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'.

53f2ffa80c rebase: write a reflog entry when finishing
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
finished: returning to refs/heads/master" can be helpful in
understanding what is going on.

9553d2b263 format-patch: preserve subject newlines with -k
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.

5b38456ec7 mailinfo: always clean up rfc822 header folding
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.

00ebc97748 t: test subject handling in format-patch / am pipeline
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").

3eafdc961f remote: allow "-t" with fetch mirrors
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.

The option can be used to check if read-tree with the same set of other
options like "-m" and "-u" would succeed without actually changing either
the index or the working tree.

The relevant tests in the t10?? range were extended to do a read-tree -n
before the real read-tree to make sure neither the index nor any local
files were changed with -n and the same exit code as without -n is
returned. The helper functions added for that purpose reside in the new
t/lib-read-tree.sh file.

The only exception is #13 in t1004 ("unlinking an un-unlink-able
symlink"). As this is an issue of wrong directory permissions it is not
detected with -n.

73546c085d handle_options(): do not miscount how many arguments were used
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.

06eb708f33 config: always parse GIT_CONFIG_PARAMETERS during git_config
Previously we parsed GIT_CONFIG_PARAMETERS lazily into a
linked list, and then checked that list during future
invocations of git_config. However, that ignores the fact
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
time. It's generally not very big, and it's no more work
than parsing the config files, anyway.

As a bonus, we can ditch all of the linked list storage code
entirely, making the code much simpler.

The test unfortunately still does not pass because of an
unrelated bug in handle_options.

0508fe533d combine-diff: respect textconv attributes
When doing a combined diff, we did not respect textconv attributes at
all. This generally lead to us printing "Binary files differ" when we
could show a combined diff of the converted text.

This patch converts file contents according to textconv attributes. The
implementation is slightly ugly; because the textconv code is tightly
linked with the diff_filespec code, we temporarily create a diff_filespec
during conversion. In practice, though, this should not create a
performance problem.

4d5f347199 combine-diff: handle binary files as binary
The combined diff code path is totally different from the
regular diff code path, and didn't handle binary files at
all. The results of a combined diff on a binary file could
range from annoying (since we spewed binary garbage,
possibly upsetting the user's terminal), to wrong (embedded
NULs caused us to show incorrect diffs, with lines truncated
at the NUL character), to potential security problems
(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
will show which parents had which blob.

f143d9c695 userdiff/perl: tighten BEGIN/END block pattern to reject here-doc delimiters
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.

f5b7ce1b90 tests: make test_expect_code quieter on success
A command exiting with the expected status is not particularly
notable.

While the indication of progress might be useful when tracking down
where in a test a failure has happened, the same applies to most other
test helpers, which are quiet about success, so this single helper's
output stands out in an unpleasant way.  An alternative method for
showing progress information might to invent a --progress option that
runs tests with "set -x", or until that is available, to run tests
using commands like

	prove -v -j2 --shuffle --exec='sh -x' t2202-add-addremove.sh

f12c66b9bb userdiff/perl: anchor "sub" and "package" patterns on the left
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.

d64d6cdc20 t4018 (funcname patterns): minor cleanups
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.

f792a0b88e t4018 (funcname patterns): make configuration easier to track
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.

5b5e45949b t4018 (funcname patterns): make .gitattributes state easier to track
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.

42536dd9b9 do not read beyond end of malloc'd buffer
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.

6db41050a3 Revert "Merge branch 'en/merge-recursive'"
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.

2d370d2fbc notes remove: --ignore-missing
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.

c3ab1a8e4c notes remove: allow removing more than one
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.

a87247731e ls-remote: the --exit-code option reports "no matching refs"
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.

ba67aaf2d0 git-sh-i18n--envsubst: our own envsubst(1) for eval_gettext()
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

d4e98b581b Submodules: Don't parse .gitmodules when it contains, merge conflicts
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.

4dd1fbc7b1 Bigfile: teach "git add" to send a large file straight to a pack
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.

28911091c1 sparse checkout: do not eagerly decide the fate for whole directory
Sparse-setting code follows closely how files are excluded in
read_directory(), every entry (including directories) are fed to
excluded_from_list() to decide if the entry is suitable. Directories
are treated no different than files. If a directory is matched (or
not), the whole directory is considered matched (or not) and the
process moves on.

This generally works as long as there are no patterns to exclude parts
of the directory. In case of sparse checkout code, the following patterns

  t
  !t/t0000-basic.sh

will produce a worktree with full directory "t" even if t0000-basic.sh
is requested to stay out.

By the same reasoning, if a directory is to be excluded, any rules to
re-include certain files within that directory will be ignored.

Fix it by always checking files against patterns. If no pattern can be
used to decide whether an entry is in our out
(ie. excluded_from_list() returns -1), the entry will be
included/excluded the same as their parent directory.

This patch makes git-grep die() when -P is used on command line together
with -E/--extended-regexp or -F/--fixed-strings.

This also makes it bail out when grep.extendedRegexp is enabled.

But `git grep -G -P pattern` and `git grep -E -G -P pattern` still work

365c2aaafc t1507: avoid "${parameter<op>'word'}" inside double-quotes
Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh.  Modern POSIX compliant shells (e.g. dash,
ksh, bash) all seem to interpret POSIX "2.6.2 Parameter Expansion" that
says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.

Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group.  We can avoid this issue and future-proof the
test by a slight rewrite.

8c5cea0095 tests: check git does not barf on merge.ff values for future versions of git
Maybe some day in the future we will want to support a syntax
like

	[merge]
		ff = branch1
		ff = branch2
		ff = branch3

in addition to the currently permitted "true", "false", and "only"
values.  So make sure we continue to treat such configurations as
though an unknown variable had been defined rather than erroring out,
until it is time to implement such a thing, so configuration files
using such a facility can be shared between present and future git.

While at it, add a few missing && and start the "combining --squash
and --no-ff" test with a known state so we can be sure it does not
succeed or fail for the wrong reason.

3fc0dbf00b tests: teach verify_parents to check for extra parents
Currently verify_parents only makes sure that the earlier parents of
HEAD match the commits given, and does not care if there are more
parents.  This makes it harder than one would like to check that, for
example, parent reduction works correctly when making an octopus.

Fix it by checking that HEAD^(n+1) is not a valid commit name.

fast-forward one commit ahead but actually created a merge.

The parsing of the additional command line parameters supplied to

branch.<name>.mergeoptions, the earlier value was overwritten.

We should first read all the merge.* configuration, override them by
reading from branch.<name>.mergeoptions and then finally read from
the command line.

This patch should fix it, even though I now strongly suspect that
branch.<name>.mergeoptions that gives a single command line that
needs to be parsed was likely to be an ill-conceived idea to begin
with.  Sigh...

73151df0cf tests: eliminate unnecessary setup test assertions
Most of git's tests write files and define shell functions and
variables that will last throughout a test script at the top of
the script, before all test assertions:

	. ./test-lib.sh

	VAR='some value'
	export VAR

	>empty

	fn () {
		do something
	}

	test_expect_success 'setup' '
		... nontrivial commands go here ...
	'

Two scripts use a different style with this kind of trivial code
enclosed by a test assertion; fix them.  The usual style is easier to
read since there is less indentation to keep track of and no need to
worry about nested quotes; and on the other hand, because the commands
in question are trivial, it should not make the test suite any worse
at catching future bugs in git.

While at it, make some other small tweaks:

 - spell function definitions with a space before () for consistency
   with other scripts;

 - use the self-contained command "git mktree </dev/null" in
   preference to "git write-tree" which looks at the index when
   writing an empty tree.

6aaeca900b merge-one-file: fix broken merges with alternate work trees
The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.

For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.

This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!

This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.

While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

cf1af1b1f3 add tests for merge-index / merge-one-file
There were no tests for either, except a brief use in
t1200-tutorial.

These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.

For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.

This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

The category is specified for each project by the $GIT_DIR/category file
or the 'gitweb.category' variable in its configuration file. By default,
projects are put in the $project_list_default_category category.

Note:
- Categories are always sorted alphabetically, with projects in
  each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
  category headers are only displayed for projects present on the page.

The feature is inspired from Sham Chukoury's patch for the XMMS2
gitweb, but has been rewritten for the current gitweb code. The CSS
for categories is inspired from Gustavo Sverzut Barbieri's patch to
group projects by path.

Thanks to Florian Ragwitz for Perl tips.

12b1443c2c gitweb: Restructure projects list generation
Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.

Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects.  Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.

Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed).  Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.

Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.

The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results).  If 'ctags' feature is disabled, then searching by tag is
too.

The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.

Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.

While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.

51670fc87e Improve error handling when parsing dirstat parameters
When encountering errors or unknown tokens while parsing parameters to the
--dirstat option, it makes sense to die() with an error message informing
the user of which parameter did not make sense. However, when parsing the
diff.dirstat config variable, we cannot simply die(), but should instead
(after warning the user) ignore the erroneous or unrecognized parameter.
After all, future Git versions might add more dirstat parameters, and
using two different Git versions on the same repo should not cripple the
older Git version just because of a parameter that is only understood by
a more recent Git version.

This patch fixes the issue by refactoring the dirstat parameter parsing
so that parse_dirstat_params() keeps on parsing parameters, even if an
earlier parameter was not recognized. When parsing has finished, it returns
zero if all parameters were successfully parsed, and non-zero if one or
more parameters were not recognized (with appropriate error messages
appended to the 'errmsg' argument).

The parse_dirstat_params() callers then decide (based on the return value
from parse_dirstat_params()) whether to warn and ignore (in case of
diff.dirstat), or to warn and die (in case of --dirstat).

The patch also adds a couple of tests verifying the correct behavior of
--dirstat and diff.dirstat in the face of unknown (possibly future) dirstat
parameters.

1c57a627bf New --dirstat=lines mode, doing dirstat analysis based on diffstat
This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.

The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).

For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.

In linux-2.6.git, running the three different --dirstat modes:

  time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null
vs.
  time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null
vs.
  time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null

yields the following average runtimes on my machine:

 - "changes" (default): ~6.0 s
 - "lines":             ~9.6 s
 - "files":             ~0.1 s

So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.

The patch also includes documentation and tests for the new dirstat mode.

333f3fb0c5 Refactor --dirstat parsing; deprecate --cumulative and --dirstat-by-file
Instead of having multiple interconnected dirstat-related options, teach
the --dirstat option itself to accept all behavior modifiers as parameters.

 - Preserve the current --dirstat=<limit> (where <limit> is an integer
   specifying a cut-off percentage)
 - Add --dirstat=cumulative, replacing --cumulative
 - Add --dirstat=files, replacing --dirstat-by-file
 - Also add --dirstat=changes and --dirstat=noncumulative for specifying the
   current default behavior. These allow the user to reset other --dirstat
   parameters (e.g. 'cumulative' and 'files') occuring earlier on the
   command line.

The deprecated options (--cumulative and --dirstat-by-file) are still
functional, although they have been removed from the documentation.

Allow multiple parameters to be separated by commas, e.g.:
  --dirstat=files,10,cumulative

Update the documentation accordingly, and add testcases verifying the
behavior of the new syntax.

58a8756a98 Make --dirstat=0 output directories that contribute < 0.1% of changes
The expected output from --dirstat=0, is to include any directory with
changes, even if those changes contribute a minuscule portion of the total
changes. However, currently, directories that contribute less than 0.1% are
not included, since their 'permille' value is 0, and there is an
'if (permille)' check in gather_dirstat() that causes them to be ignored.

This test is obviously intended to exclude directories that contribute no
changes whatsoever, but in this case, it hits too broadly. The correct
check is against 'this_dir' from which the permille is calculated. Only if
this value is 0 does the directory truly contribute no changes, and should
be skipped from the output.

This patches fixes this issue, and updates corresponding testcases to
expect the new behvaior.

Currently, t4013 is the only selftest that exercises the --dirstat machinery,

This patch adds a new selftest - t4047-diff-dirstat.sh - which prepares a
commit containing:
 - unchanged files, changed files and files with rearranged lines
 - copied files, moved files, and unmoved files

It then verifies the correct dirstat output for that commit in the following
dirstat modes:
 - --dirstat
 - -X
 - --dirstat=0
 - -X0
 - --cumulative
 - --dirstat-by-file
 - (plus combinations of the above)

Each of the above tests are also run with:
 - no rename detection
 - rename detection (-M)
 - expensive copy detection (-C -C)

9b01f0038b blame: tolerate bogus e-mail addresses a bit better
The names and e-mails are sanitized by fmt_ident() when creating commits,
so that they do not contain "<" nor ">", and the "committer" and "author"
lines in the commit object will always be in the form:

    ("author" | "committer") name SP "<" email ">" SP timestamp SP zone

When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".

We should instead look for SP followed by "<", to match the logic of the
side that formats these lines.

c192f9c865 git-rebase--interactive.sh: preserve-merges fails on merges created with no-ff
'git rebase' uses 'git merge' to preserve merges (-p).  This preserves
the original merge commit correctly, except when the original merge
commit was created by 'git merge --no-ff'.  In this case, 'git rebase'
will fail to preserve the merge, because during 'git rebase', 'git
merge' will simply fast-forward and skip the commit.  For example:

               B
              / \
             A---M
            /
    ---o---O---P---Q

If we try to rebase M onto P, we lose the merge commit and this happens:

                 A---B
                /
    ---o---O---P---Q

To correct this, we simply do a "no fast-forward" on all merge commits
when rebasing.  Since by the time we decided to do a 'git merge' inside
'git rebase', it means there was a merge originally, so 'git merge'
should always create a merge commit regardless of what the merge
branches look like. This way, when rebase M onto P from the above
example, we get:

                   B
                  / \
                 A---M
                /
    ---o---O---P---Q

4d03c18a3e pretty: quote rfc822 specials in email addresses
If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.

In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:

   From: Foo B. Bar <author@example.com>

without quotes, and properly quote the "." when they send
the actual mail.  Others may not, or may screw up harder
things like:

  From: Foo "The Baz" Bar <author@example.com>

For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.

So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all
MUAs happy.

75973b2cb5 Fix "add -u" that sometimes fails to resolve unmerged paths
"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.

It ignored the output from the diff-files that indicated that a path is
unmerged.  For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.

As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.

Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.

The changes to the test vector in t2200 illustrates the nature of the bug
and the fix.  The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

f1e9c548ce date: avoid "X years, 12 months" in relative dates
When relative dates are more than about a year ago, we start
writing them as "Y years, M months".  At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:

  Y = days / 365
  M = (days % 365 + 15) / 30

This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").

We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".

Implement this differently with months of size

  onemonth = 365/12

so that

  totalmonths = (long)( (days + onemonth/2)/onemonth )
  years = totalmonths / 12
  months = totalmonths % 12

In order to do this without floats, we write the first formula as

  totalmonths = (days*12*2 + 365) / (365*2)

c0f19bf3b9 tests: check error message from run_command
In git versions starting at v1.7.5-rc0~29^2 until v1.7.5-rc3~2 (Revert
"run-command: prettify -D_FORTIFY_SOURCE workaround", 2011-04-18)
fixed it, the run_command facility would write a truncated error
message when the command is present but cannot be executed for some
other reason.  For example, if I add a 'hello' command to git:

	$ echo 'echo hello' >git-hello
	$ chmod +x git-hello
	$ PATH=.:$PATH git hello
	hello

and make it non-executable, this is what I normally get:

	$ chmod -x git-hello
	$ git hello
	fatal: cannot exec 'git-hello': Permission denied

But with the problematic versions, we get disturbing output:

	$ PATH=.:$PATH git hello
	fatal: $

Add some tests to make sure it doesn't happen again.

The hello-script used in these tests uses cat instead of echo because
on Windows the bash spawned by git converts LF to CRLF in text written
by echo while the bash running tests does not, causing the test to
fail if "echo" is used.  Thanks to Hannes for noticing.

990f6e30eb format-patch: wrap email addresses after long names
We already wrap names in "from" headers, which tend to be
the long part of an address. But it's also possible for a
long name to not be wrapped, but to make us want to wrap the
email address. For example (imagine for the sake of
readability we want to wrap at 50 characters instead of 78):

  From: this is my really long git name <foo@example.com>

The name does not overflow the line, but the name and email
together do. So we would rather see:

  From: this is my really long git name
    <git@example.com>

Because we wrap the name separately during add_rfc2047, we
neglected this case. Instead, we should see how long the
final line of the wrapped name ended up, and decide whether
or not to wrap based on that. We can't break the address
into multiple parts, so we either leave it with the name, or
put it by itself on a line.

Two tests looked for "[Uu]sage" in the output, but we cannot expect the
l10n to use that phrase.  Mark them with test_i18ngrep so that in later
versions we can test truly localized versions with the same tests, not
just GETTEXT_POISON that happens to keep the original string in the

e3b02bc953 t3306,t5304: avoid clock skew issues
On systems where the local time and file modification time may be out of
sync (e.g. test directory on NFS) t3306 and t5305 can fail because prune
compares times such as "now" (client time) with file modification times
(server times for remote file systems). I.e., these are spurious test
failures.

Avoid this by setting the relevant modification times to the local time.

Noticed on a system with as little as 2s time skew.

ff7f089ed1 mergetool: Teach about submodules
When the index has conflicted submodules, mergetool used to mildly
clobber the module, renaming it to mymodule.BACKUP.nnnn, then failing to
copy it non-recursively.

Recognize submodules and offer a resolution instead:

  Submodule merge conflict for 'Shared':
    {local}: submodule commit ad9f12e3e6205381bf2163a793d1e596a9e211d0
    {remote}: submodule commit f5893fb70ec5646efcd9aa643c5136753ac89253
  Use (l)ocal or (r)emote, or (a)bort?

Selecting a commit will stage it, but not update the submodule (as git
does had there been no conflict). Type changes are also supported,
should the path be a submodule on one side, and a file, symlink,
directory, or deleted on the other.

cabdee2c5e i18n: do not overuse C_LOCALE_OUTPUT
It is too coarse-grained way that led to artificial splitting of a
logically single test case into "do" and "check only without poison".
As the majority of check is done by comparing expected and actual output
stored in a file with test_cmp anyway, just introduce test_i18ncmp that
pretends the actual output matched the expected one when gettext-poison
is in effect.

e96c19c50f config: support values longer than 1023 bytes
parse_value in config.c has a static buffer of 1024 bytes that it
parse the value into. This can sometimes be a problem when a
config file contains very long values.

It's particularly amusing that git-config already is able to write
such files, so it should probably be able to read them as well.

Fix this by using a strbuf instead of a fixed-size buffer.

2ff3a80334 Teach --dirstat not to completely ignore rearranged lines within a file
Currently, the --dirstat analysis ignores when lines within a file are
rearranged, because the "damage" calculated by show_dirstat() is 0.
However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.

Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.

Also, skip --dirstat analysis when the object names are the same (e.g. for
a pure file rename).

0133dab75d --dirstat-by-file: Make it faster and more correct
Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().

But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.

This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.

The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.
