For the pager choice (and the choice to paginate) to reflect the
current repository configuration, the repository needs to be
located first.

Without this change, “git -p bundle” does not always
respect the repository-local “[core] pager” setting.

It is hard to notice because subcommands other than

Jonathan Nieder 314eeb6e48 cherry-pick/revert: Use advise() for hints
When cherry-pick fails after picking a large series of commits, it can
be hard to pick out the error message and advice.  Prefix the advice

      After resolving the conflicts,
    mark the corrected paths with 'git add <paths>' or 'git rm <paths>'

Jonathan Nieder 130ab8ab9c Eliminate “Finished cherry-pick/revert” message
When cherry-pick was written (v0.99.6~63, 2005-08-27), “git commit”
was quiet, and the output from cherry-pick provided useful information
about the progress of a rebase.

Now next to the output from “git commit”, the cherry-pick notification
is so much noise (except for the name of the picked commit).

 $ git cherry-pick ..topic

The noise is especially troublesome when sifting through the output of
a rebase or multiple cherry-pick that eventually failed.

With the commit subject, it is already not hard to figure out where
the commit came from.  So drop the “Finished” message.

David D. Kilzer 3235b7053c git-svn: fix fetch with deleted tag
Currently git-svn assumes that two tags created from the same
revision will have the same repo url, so it uses a ref to the
tag without checking that its url matches the current url.

This causes issues when fetching an svn repo where a tag was
created, deleted, and then recreated under the following
circumstances:

- Both tags were copied from the same revision.
- Both tags had the same name.
- Both tags had different repository paths.
- [Optional] Both tags have a file with the same name but
  different content.

When all four conditions are met, a checksum mismatch error
occurs because the content of two files with the same path
differs (see t/t9155--git-svn-fetch-deleted-tag.sh):

    Checksum mismatch: ChangeLog 065854....
    expected: ce771b....
         got: 9563fd....

When only the first three conditions are met, no error occurs
but the tag in git matches the first (deleted) tag instead of
the last (most recent) tag (see
t/t9156-git-svn-fetch-deleted-tag-2.sh).

The fix is to verify that the repo url for the ref matches the
current url.  If the urls do not match, then a "tail" is grown
on the tag name by appending a dash and rechecking the new ref's
repo url until either a matching repo url is found or a new tag
is created.

Jonathan Nieder 24f1136894 t9010 (svn-fe): use Unix-style path in URI
Ever since v1.6.3-rc0~101^2~14 (Tests on Windows: $(pwd) must return
Windows-style paths, 2009-03-13), there is a subtle difference between
$(pwd) and $PWD in tests: the former returns Windows-style paths as
might be output by git and the latter Unix-style paths which msys
programs tend to prefer.

In file:// URIs, Unix-style paths are needed.  Before: “svn export”
declares it cannot find

Jason Evans 951f316470 Add treap implementation
Provide macros to generate a type-specific treap implementation and
various functions to operate on it. It uses obj_pool.h to store memory
nodes in a treap.  Previously committed nodes are never removed from
the pool; after any *_commit operation, it is assumed (correctly, in
the case of svn-fast-export) that someone else must care about them.

Treaps provide a memory-efficient binary search tree structure.
Insertion/deletion/search are about as about as fast in the average
case as red-black trees and the chances of worst-case behavior are
vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
behavior is a small price to pay, given that treaps are much simpler
to implement.

David Barr 4709455db3 Add memory pool library
Add a memory pool library implemented using C macros. The
obj_pool_gen() macro creates a type-specific memory pool.

The memory pool library is distinguished from the existing specialized
allocators in alloc.c by using a contiguous block for all allocations.
This means that on one hand, long-lived pointers have to be written as
offsets, since the base address changes as the pool grows, but on the
other hand, the entire pool can be easily written to the file system.
This could allow the memory pool to persist between runs of an
application.

For the svn importer, such a facility is useful because each svn
revision can copy trees and files from any previous revision.  The
relevant information for all revisions has to persist somehow to
support incremental runs.

[rr: minor cleanups]

Elijah Newren cf65426de6 pull --rebase: Avoid spurious conflicts and reapplying unnecessary patches
Prior to c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), pull --rebase would run

  git rebase $merge_head

which resulted in a call to

  git format-patch ... --ignore-if-in-upstream $merge_head..$cur_branch

This resulted in patches from $merge_head..$cur_branch being applied, as
long as they did not already exist in $cur_branch..$merge_head.

Unfortunately, when upstream is rebased, $merge_head..$cur_branch also
refers to "old" commits that have already been rebased upstream, meaning
that many patches that were already fixed upstream would be reapplied.
This could result in many spurious conflicts, as well as reintroduce
patches that were intentionally dropped upstream.

So the algorithm was changed in c85c792 (pull --rebase: be cleverer with
rebased upstream branches, 2008-01-26) and d44e712 (pull: support rebased
upstream + fetch + pull --rebase, 2009-07-19).  Defining $old_remote_ref to
be the most recent entry in the reflog for @{upstream} that is an ancestor
of $cur_branch, pull --rebase was changed to run

  git rebase --onto $merge_head $old_remote_ref

which results in a call to

  git format-patch ... --ignore-if-in-upstream $old_remote_ref..$cur_branch

The whole point of this change was to reduce the number of commits being
reapplied, by avoiding commits that upstream already has or had.

In the rebased upstream case, this change achieved that purpose.  It is
worth noting, though, that since $old_remote_ref is always an ancestor of
$cur_branch (by its definition), format-patch will not know what upstream
is and thus will not be able to determine if any patches are already
upstream; they will all be reapplied.

In the non-rebased upstream case, this new form is usually the same as the
original code but in some cases $old_remote_ref can be an ancestor of

   $(git merge-base $merge_head $cur_branch)

meaning that instead of avoiding reapplying commits that upstream already
has, it actually includes more such commits.  Combined with the fact that
format-patch can no longer detect commits that are already upstream (since
it is no longer told what upstream is), results in lots of confusion for
users (e.g. "git is giving me lots of conflicts in stuff I didn't even
change since my last push.")

Cases where additional commits could be reapplied include forking from a
commit other than the tracking branch, or amending/rebasing after pushing.
Cases where the inability to detect upstreamed commits cause problems
include independent discovery of a fix and having your patches get
upstreamed by some alternative route (e.g. pulling your changes to a third
machine, pushing from there, and then going back to your original machine
and trying to pull --rebase).

Fix the non-rebased upstream case by ignoring $old_remote_ref whenever it
is contained in $(git merge-base $merge_head $cur_branch).  This should
have no affect on the rebased upstream case.

Raja R Harinath 7e7db5e452 fast-import: export correctly marks larger than 2^20-1
dump_marks_helper() has a bug when dumping marks larger than 2^20-1,
i.e., when the sparse array has more than two levels.  The bug was
that the 'base' counter was being shifted by 20 bits at level 3, and
then again by 10 bits at level 2, rather than a total shift of 20 bits
in this argument to the recursive call:

  (base + k) << m->shift

There are two ways to fix this correctly, the elegant:

  (base + k) << 10

and the one I chose due to edit distance:

  base + (k << m->shift)

Matthieu Moy e6c111b4c0 unpack_trees: group error messages by type
When an error is encountered, it calls add_rejected_file() which either
- directly displays the error message and stops if in plumbing mode
  (i.e. if show_all_errors is not initialized at 1)
- or stores it so that it will be displayed at the end with display_error_msgs(),

Storing the files by error type permits to have a list of files for
which there is the same error instead of having a serie of almost
identical errors.

As each bind_overlap error combines a file and an old file, a list cannot be
done, therefore, theses errors are not stored but directly displayed.

Matthieu Moy cd035b1cef rebase -i: add exec command to launch a shell command
The typical usage pattern would be to run a test (or simply a compilation
command) at given points in history.

The shell command is ran (from the worktree root), and the rebase is
stopped when the command fails, to give the user an opportunity to fix
the problem before continuing with "git rebase --continue".

This needs a little rework of skip_unnecessary_picks, which wasn't robust
enough to deal with lines like

  exec >"file    name with many spaces"

in the todolist. The new version extracts command, sha1 and rest from
each line, but outputs the line itself verbatim to avoid changing the

Jakub Narebski d8faea9d18 diff: strip extra "/" when stripping prefix
There are two ways a user might want to use "diff --relative":

  1. For a file in a directory, like "subdir/file", the user
     can use "--relative=subdir/" to strip the directory.

  2. To strip part of a filename, like "foo-10", they can
     use "--relative=foo-".

We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".

We can do what the user means here and strip the extra "/" (and only a
slash).  We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

Nguyễn Thái Ngọc Duy 74da98f9c7 unpack-trees: mark new entries skip-worktree appropriately
Sparse checkout narrows worktree down based on the skip-worktree bit
before and after $GIT_DIR/info/sparse-checkout application. If it does
not have that bit before but does after, a narrow is detected and the
file will be removed from worktree.

New files added by merge, however, does not have skip-worktree bit. If
those files appear to be outside checkout area, the same rule applies:
the file gets removed from worktree even though they don't exist in
worktree.

Just pretend they have skip-worktree before in that case, so the rule
is ignored.

Nguyễn Thái Ngọc Duy 700e66d661 unpack-trees: let read-tree -u remove index entries outside sparse area
To avoid touching the worktree outside a sparse checkout,
when the update flag is enabled unpack_trees() clears the
CE_UPDATE and CE_REMOVE flags on entries that do not match the
sparse pattern before actually committing any updates to the
index file or worktree.

The effect on the index was unintentional; sparse checkout was
never meant to prevent index updates outside the area checked
out.  And the result is very confusing: for example, after a
failed merge, currently "git reset --hard" does not reset the
state completely but an additional "git reset --mixed" will.

So stop clearing the CE_REMOVE flag.  Instead, maintain a
CE_WT_REMOVE flag to separately track whether a particular
file removal should apply to the worktree in addition to the
index or not.

The CE_WT_REMOVE flag is used already to mark files that
should be removed because of a narrowing checkout area.  That
usage will still apply; do not clear the CE_WT_REMOVE flag
in that case (detectable because the CE_REMOVE flag is not
set).

This bug masked some other bugs illustrated by the test
suite, which will be addressed by later patches.

Nguyễn Thái Ngọc Duy eec3fc0309 unpack-trees: only clear CE_UPDATE|CE_REMOVE when skip-worktree is always set
The purpose of this clearing is, as explained in comment, because
verify_*() may set those bits before apply_sparse_checkout() is
called. By that time, it's not clear whether an entry will stay in
checkout area or out. After $GIT_DIR/info/sparse-checkout is applied,
we know what entries will be in finally. It's time to clean unwanted
bits.

That works perfectly when checkout area remains unchanged. When
checkout area changes, apply_sparse_checkout() may set CE_UPDATE
or CE_WT_REMOVE to widen/narrow checkout area. Doing the clearing
after apply_sparse_checkout() may clear those widening/narrowing
bits unexpectedly.

So, only do that on entries that are not affected by checkout area
changes (i.e. skip-worktree bit does not change after
apply_sparse_checkout).

This code does not actually fix anything though, just
future-proof. The removed code and the narrow/widen code inside
apply_sparse_checkout are currently independent (narrow code never
sets CE_REMOVE, widen code sets CE_UPDATE, but ce_skip_worktree()
would be false).

Jens Lehmann aee9c7d654 Submodules: Add the new "ignore" config option for diff and status
The new "ignore" config option controls the default behavior for "git
status" and the diff family. It specifies under what circumstances they
consider submodules as modified and can be set separately for each
submodule.

The command line option "--ignore-submodules=" has been extended to accept
the new parameter "none" for both status and diff.

Users that chose submodules to get rid of long work tree scanning times
might want to set the "dirty" option for those submodules. This brings
back the pre 1.7.0 behavior, where submodule work trees were never
scanned for modifications. By using "--ignore-submodules=none" on the
command line the status and diff commands can be told to do a full scan.

This option can be set to the following values (which have the same name
and meaning as for the "--ignore-submodules" option of status and diff):

"all": All changes to the submodule will be ignored.

"dirty": Only differences of the commit recorded in the superproject and
	the submodules HEAD will be considered modifications, all changes
	to the work tree of the submodule will be ignored. When using this
	value, the submodule will not be scanned for work tree changes at
	all, leading to a performance benefit on large submodules.

"untracked": Only untracked files in the submodules work tree are ignored,
	a changed HEAD and/or modified files in the submodule will mark it
	as modified.

"none" (which is the default): Either untracked or modified files in a
	submodules work tree or a difference between the subdmodules HEAD
	and the commit recorded in the superproject will make it show up
	as changed. This value is added as a new parameter for the
	"--ignore-submodules" option of the diff family and "git status"
	so the user can override the settings in the configuration.

The dcommit command fails if an otherwise unmodified file has

    Cannot dcommit with a dirty index.  Commit your changes

This happens because "git diff-index" reports a difference
between the index and the filesystem:

The fix is to run "git update-index --refresh" before
"git diff-index" as is done in git-rebase and
git-rebase--interactive before "git diff-files".

This changes dcommit to display a list of modified files before
exiting.

Also add a similar test case for "git svn rebase".

Brandon Casey 938791cd01 git-rebase--interactive.sh: use printf instead of echo to print commit message
On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences.  This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences.  In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail.  Neither is desirable.

So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.

Also, add a test to test for this breakage.

 - Do not hard-code object IDs.  We may use a different hash some day.

 - Use test_cmp in preference to the test builtin.  The former

 - Guard all test code with test_expect_success.  This makes it much

 - Use subshells to make the current directory easier to track.
   Outside of any subshell, the current directory is always

Since 9d2e942 (decode file:// and ssh:// URLs, 2010-05-23) the URL
logic unquotes escaped URLs.  For the %2B type of escape, this is
conformant with RFC 2396.  However, it also unquotes + into a space
character, which is only appropriate for the query strings in HTTP.
This notably broke fetching from the gtk+ repository.

We cannot just remove the corresponding code since the same
url_decode_internal() is also used by the HTTP backend to decode query
parameters.  Introduce a new argument that controls whether the +
decoding happens, and use it only in the (client-side) url_decode().

Christian Couder 6bc83cdd0b t3508: add check_head_differs_from() helper function and use it
In a test like:

test "$(git rev-parse --verify HEAD)" != "$(git rev-parse --verify fourth)"

the --verify does not accomplish much, since the exit status of
git rev-parse is not propagated to test. So it is more robust to
define and use the helper functions check_head_differs_from() and
check_head_equals() as done by this patch.

Junio C Hamano 840b3ca758 rebase: protect against diff.renames configuration
We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".

The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.

For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.

In any case, here is a much straightforward fix for "rebase".

Jonathan Nieder e877a4c11a t3400 (rebase): whitespace cleanup
This test used 5-space indents since it was added in 2005, but
recently the temptation to use tabs to indent has been too
strong, resulting in uneven whitespace.  Switch over completely
to tabs.

While at it, use a more modern style for consistency with other
tests:

 - names of tests go on the same line as test_expect_success;
 - extra whitespace after > redirection operators is removed.

Junio C Hamano 18cdf802ca Teach "apply --index-info" to handle rename patches
With v1.5.3.2~14 (apply --index-info: fall back to current index for
mode changes, 2007-09-17), git apply learned to stop worrying
about the lack of diff index line when a file already present in the
current index had no content change.

But it still worries too much: for rename patches, it is checking
that both the old and new filename are present in the current
index.  This makes no sense, since a file rename generally
involves creating a file there was none before.

So just check the old filename.

Noticed while trying to use “git rebase” with diff.renames = copies.

Jonathan Nieder 5d27485944 t4150 (am): futureproof against failing tests
Most tests in t4150 begin by navigating to a sane state and
applying some patch:

	git checkout first &&
	git am patch1

If a previous test left behind unmerged files or a .git/rebase-apply
directory, they are untouched and the test fails, causing later tests
to fail, too.  This is not a problem in practice because none of the
tests leave a mess behind.

But as a futureproofing measure, it is still best to avoid the problem
and clean up at the start of each test.  In particular, this
simplifies the process of adding new tests that are known to fail.

Jonathan Nieder 800f11040d t4150 (am): style fix
Place setup commands in test_expect_success blocks.  This makes the
rare event of the setup commands breaking on some platform easier to
diagnose, and more importantly, it visually distinguishes where
each test begins and ends.

Instead of running test -z against the result of "git diff" command
substitution, use "git diff --exit-code", to improve output when
running with the "-v" option.

Use test_cmp in place of "test $(foo) = $(bar)" for similar reasons.

Remove whitespace after the > and < redirection operators for
consistency with other tests.

The order of arguments to test_cmp is "test_cmp expected actual".

These two tests weren't about how "git reflog show <branch>" exits when
there is no reflog, but were about "checkout" and "branch" create or not
create reflog when creating a new <branch>.  Update the tests to check

Brandon Casey 77b5be2aba t/{t5541,lib-httpd}: replace problematic '!()' notation with test_must_fail
The '!()' notation is interpreted as a pattern-list on Ksh.  The Ksh man
page describe it as follows:

   !(pattern-list)
      Matches anything except one of the given patterns.

Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list.  If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.

Brandon Casey 460d562eab t/t3700: convert two uses of negation operator '!' to use test_must_fail
These two lines use the negation '!' operator to negate the result of a
simple command.  Since these commands do not contain any pipes or other
complexities, the test_must_fail function can be used and is preferred
since it will additionally detect termination due to a signal.

This was noticed because the second use of '!' does not include a space
between the '!' and the opening parens.  Ksh interprets this as follows:

   !(pattern-list)
      Matches anything except one of the given patterns.

Elijah Newren 7f40ab0916 fast-export: Add a --full-tree option
This option adds symmetry with fast-import, enabling it to also work with
complete trees instead of just incremental changes.  It works by issuing a
'deleteall' directive with each commit and then listing the full set of
files that make up that commit, rather than just showing the list of files
that have changed since the (first) parent commit.  Note that this
functionality is automatically turned on when using --import-marks together
with path limiting in order to avoid dropping important but unchanged
files.

This functionality is desired when using hand-written filters along with
'fast-export | some-filter | fast-import' as it can be easier to write
<some-filter> in terms of complete trees than incremental changes.

We could avoid the need to add this option by simply always turning it on.
While the end result would be identical, it would slow things down slightly
by printing many more filenames per commit which goes somewhat against the
'fast' in 'fast-export'.

Elijah Newren 4087a02e45 fast-export: Fix dropping of files with --import-marks and path limiting
Since fast-export operates by listing file changes since the (first) parent
commit, when using --import-marks and path limiting and using a wider list
of paths than in previous runs, files from the new path(s) will silently be
omitted from the result unless or until a commit which explicitly changes
those files.  The resulting repository in such cases is broken and makes no
sense.

This commit fixes this by having fast-export work with complete trees
instead of incremental changes (when both --import-marks and path limiting
are used).  It works by issuing a 'deleteall' directive with each commit and
then listing the full set of files that make up that commit, rather than
just showing the list of files that have changed since the (first) parent
commit.

Christian Couder 7b53b92fdb revert: report success when using option --strategy
"git cherry-pick foo" has always reported success with
"Finished one cherry-pick" but "cherry-pick --strategy"
does not print anything. So move the code to write that
message from do_recursive_merge() to do_cherry_pick()
so other strategies can share it.

This patch also refactors the code that prints a message
like "Automatic cherry-pick failed. <help message>". This
code was duplicated in both do_recursive_merge() and
do_pick_commit().

To do that, now do_recursive_merge() returns an int to signal
success or failure. And in case of failure we just return 1
from do_pick_commit() instead of doing "exit(1)" from either
do_recursive_merge() or do_pick_commit().
