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.

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.

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.

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.

git-rebase--interactive.sh: rework skip_unnecessary_picks
Commit cd035b1c introduced the exec command to interactive rebase. In
doing so, it modified the way that skip_unnecessary_picks iterates through
the list of rebase commands so that it avoided collapsing multiple spaces
into a single space. This is necessary for example if the argument to the
exec command contains a path with multiple spaces in it.
The way it did this was by reading each line of rebase commands into a
single variable, and then breaking the individual components out using
echo, sed, and cut. It used the individual broken-out components for
decision making, and was still able to write the original line to the
output file from the variable it had saved it in. But, since we only
really need to look at anything other than the first element of the line
when a 'pick' command is encountered, and even that is only necessary when
we are still searching for "unnecessary" picks, and since newer rebase
commands like 'exec' may not even require a sha1 field, let's make our read
statement parse its input into a "command" variable, and a "rest" variable,
and then only break out the sha1 from $rest, and call git-rev-parse, when
absolutely necessary.
I think this future proofs this subroutine, avoids calling git-rev-parse
unnecessarily, and possibly with bogus arguments, and still accomplishes
the goal of not mangling the $rest of the rebase command.

diff --follow: do call diffcore_std() as necessary
Usually, diff frontends populate the output queue with filepairs without
any rename information and call diffcore_std() to sort the renames out.
When --follow is in effect, however, diff-tree family of frontend has a
hack that looks like this:
diff-tree frontend
-> diff_tree_sha1()
. populate diff_queued_diff
. if --follow is in effect and there is only one change that
creates the target path, then
-> try_to_follow_renames()
-> diff_tree_sha1() with no pathspec but with -C
-> diffcore_std() to find renames
. if rename is found, tweak diff_queued_diff and put a
single filepair that records the found rename there
-> diffcore_std()
. tweak elements on diff_queued_diff by
- rename detection
- path ordering
- pickaxe filtering
We need to skip parts of the second call to diffcore_std() that is related
to rename detection, and do so only when try_to_follow_renames() did find
a rename. Earlier 1da6175 (Make diffcore_std only can run once before a
diff_flush, 2010-05-06) tried to deal with this issue incorrectly; it
unconditionally disabled any second call to diffcore_std().
This hopefully fixes the breakage.

diff --follow: do not waste cycles while recursing
The "--follow" logic is called from diff_tree_sha1() function, but the
input trees to diff_tree_sha1() are not necessarily the top-level trees
(compare_tree_entry() calls it while it recursively descends into
subtrees). When a newly created path lives in somewhere deep in the
source hierarchy, e.g. "platform/", but the rename source is in a totally
different place in the destination hierarchy, e.g. "lang-api/src/com/...",
running "try_to_find_renames()" while base is set to "platform/" is a
wasted call.
We only need to run the rename following at the very top level.

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.

configured variables are not properly set. Configure the new shellpath
accessor to handle this case.
On Windows we may not find the shell so in this case revert to simply
executing the filter command without the shell intermediate.

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)

When an error is encountered, it calls add_rejected_file() which either

(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.

merge-recursive: distinguish "removed" and "overwritten" messages
To limit the number of possible error messages, the error messages for
the case would_lose_untracked_file and would_lose_orphaned in
unpack_trees_options.msgs were handled with a single string,
parameterized by an action string ("overwritten" or "removed").
Instead, we consider them as two different cases, with unparameterized
string. This will make it easier to make separate lists sorted by error
types later.
Only the bind_overlap case still takes two %s parameters, but that's
unavoidable.

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
whitespace layout.

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.

git wrapper: allow setup_git_directory_gently() be called earlier
In the spirit of v1.4.2-rc3~34^2^2 (Call setup_git_directory() much
earlier, 2006-07-28), let run_builtin() take care of searching for a
repository for built-ins that want to make use of one if present.
So now you can mark your command with RUN_SETUP_GENTLY and use
nongit = !startup_info->have_repository;
in place of
prefix = setup_git_directory_gently(&nongit);
and everything will be the same, except the repository is
discovered a little sooner.
As v1.7.2~16^2 (2010-07-14) explains, this should allow more commands
to robustly use features like "git --paginate" that look at local
configuration before the command is actually run.
This patch sets up the infrastructure. Later patches will teach
particular commands to use it.

setup: remember whether repository was found
As v1.7.2~16^2 (git --paginate: paginate external commands
again, 2010-07-14) explains, builtins (like git config) that
do not use RUN_SETUP are not finding GIT_DIR set correctly when
it is time to launch the pager from run_builtin(). If they
were to search for a repository sooner, then the outcome of such
early repository accesses would be more predictable and reliable.
The cmd_*() functions learn whether a repository was found through the
*nongit_ok return value from setup_git_directory_gently(). If
run_builtin() is to take care of the repository search itself, that
datum needs to be retrievable from somewhere else. Use the
startup_info struct for this.
As a bonus, this information becomes available to functions such as
git_config() which might want to avoid trying to access a repository
when none is present.

The startup_info struct will collect information managed by the git
setup code, such as the prefix for relative paths passed on the
command line (i.e., path to the starting cwd from the toplevel of
the work tree) and whether a git repository has been found.
In other words, startup_info is intended to be a collection of global
variables with results that were previously returned from setup
functions. This state is global anyway (since the cwd is), even
if it is not currently tracked that way. Letting these values persist
means there is more flexibility in deciding when to run setup.
For now, the struct is empty.

gitweb: clarify search results page when no matching commit found
When searching commits for a string that never occurs, the results
page looks something like this:
projects / foo.git / search \o/
summary | ... | tree [commit] search: [ kfjdkas ] [ ]re
first ⋅ prev ⋅ next
Merge branch 'maint'
Foo: a demonstration project
Without a list of hits to compare it to, the header describing the
commit named by the hash parameter (usually HEAD) may itself look
like a hit. Add some text (“No match.”) to replace the empty
list of hits and avoid this confusion.
While at it, remove some nearby dead code, left behind from a
simplification a few years ago (v1.5.4-rc0~276^2~4, 2007-11-01).

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.

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.

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).

Add the 'diff.ignoreSubmodules' config setting
When you have a lot of submodules checked out, the time penalty to check
for dirty submodules can easily imply a multiplication of the total time
by the factor 20. This makes the difference between almost instantaneous
(< 2 seconds) and unbearably slow (> 50 seconds) here, since the disk
caches are constantly overloaded.
To this end, the submodule.*.ignore config option was introduced, but it
is per-submodule.
This commit introduces a global config setting to set a default
(porcelain) value for the --ignore-submodules option, keeping the
default at 'none'. It can be overridden by the submodule.*.ignore
setting and by the --ignore-submodules option.
Incidentally, this commit fixes an issue with the overriding logic:
multiple --ignore-submodules options would not clear the previously
set flags.

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.

git-gui: Make usage statement visible on Windows.
On Windows stdout and stderr are not connected to anything so the usage

line like 'git gui browser'. Use a messagebox on windows.
