- numstat_patch_list() also only computes local values and calls

When pack-objects is given --include-tag, it peels each tag
ref down to a non-tag object, and if that non-tag object is
going to be packed, we include the tag, too. But what
happens if we have a chain of tags (e.g., tag "A" points to
tag "B", which points to commit "C")?
We'll peel down to "C" and realize that we want to include
tag "A", but we do not ever consider tag "B", leading to a
broken pack (assuming "B" was not otherwise selected).
Instead, we have to walk the whole chain, adding any tags we
find to the pack.
Interestingly, it doesn't seem possible to trigger this
problem with "git fetch", but you can with "git clone
--single-branch". The reason is that we generate the correct
pack when the client explicitly asks for "A" (because we do
a real reachability analysis there), and "fetch" is more
willing to do so. There are basically two cases:
1. If "C" is already a ref tip, then the client can deduce
that it needs "A" itself (via find_non_local_tags), and
will ask for it explicitly rather than relying on the
include-tag capability. Everything works.
2. If "C" is not already a ref tip, then we hope for
include-tag to send us the correct tag. But it doesn't;
it generates a broken pack. However, the next step is
to do a follow-up run of find_non_local_tags(),
followed by fetch_refs() to backfill any tags we
learned about.
In the normal case, fetch_refs() calls quickfetch(),
which does a connectivity check and sees we have no
new objects to fetch. We just write the refs.
But for the broken-pack case, the connectivity check
fails, and quickfetch will follow-up with the remote,
asking explicitly for each of the ref tips. This picks
up the missing object in a new pack.
For a regular "git clone", we are similarly OK, because we
explicitly request all of the tag refs, and get a correct
pack. But with "--single-branch", we kick in tag
auto-following via "include-tag", but do _not_ do a
follow-up backfill. We just take whatever the server sent us
via include-tag and write out tag refs for any tag objects
we were sent. So prior to c6807a4 (clone: open a shortcut
for connectivity check, 2013-05-26), we actually claimed the
clone was a success, but the result was silently
corrupted! Since c6807a4, index-pack's connectivity
check catches this case, and we correctly complain.
The included test directly checks that pack-objects does not
generate a broken pack, but also confirms that "clone
--single-branch" does not hit the bug.
Note that tag chains introduce another interesting question:
if we are packing the tag "B" but not the commit "C", should
"A" be included?
Both before and after this patch, we do not include "A",
because the initial peel_ref() check only knows about the
bottom-most level, "C". To realize that "B" is involved at
all, we would have to switch to an incremental peel, in
which we examine each tagged object, asking if it is being
packed (and including the outer tag if so).
But that runs contrary to the optimizations in peel_ref(),
which avoid accessing the objects at all, in favor of using
the value we pull from packed-refs. It's OK to walk the
whole chain once we know we're going to include the tag (we
have to access it anyway, so the effort is proportional to
the pack we're generating). But for the initial selection,
we have to look at every ref. If we're only packing a few
objects, we'd still have to parse every single referenced
tag object just to confirm that it isn't part of a tag
chain.
This could be addressed if packed-refs stored the complete
tag chain for each peeled ref (in most cases, this would be
the same cost as now, as each "chain" is only a single
link). But given the size of that project, it's out of scope
for this fix (and probably nobody cares enough anyway, as
it's such an obscure situation). This commit limits itself
to just avoiding the creation of a broken pack.

We generate a series of packfiles test-1-$pack,
test-2-$pack, with different properties and then examine
them. However we always store the packname generated by
pack-objects in the variable packname_1. This probably was
meant to be packname_2 in the second test, but it turns out
that it doesn't matter: once we are done with the first
pack, we can just keep using the same $packname variable.
So let's drop the confusing "_1" parameter. At the same
time, let's give test-1 and test-2 more descriptive names,
which can help keep them straight (note that we _could_
likewise overwrite the packfiles in each test, but by using
separate filenames, we are sure that test 2 does not
accidentally use the packfile from test 1).

This test unpacks objects into a separate repository, and
accesses it by setting GIT_DIR in a subshell. We can do the
same thing these days by using "git init <repo>" and "git
-C". In most cases this is shorter, though when there are
multiple commands, we may end up repeating the "-C".
However, this repetition can actually be a good thing. This
patch also fixes a bug introduced by 512477b (tests: use
"env" to run commands with temporary env-var settings,
2014-03-18). That commit essentially converted:
(GIT_DIR=...; export GIT_DIR

into:
(GIT_DIR=... cmd1 &&
cmd2)
which obviously loses the GIT_DIR setting for cmd2 (we never
noticed the bug because it simply runs "cmd2" in the parent
repo, which means we were simply failing to test anything
interesting). By using "git -C" rather than a subshell, it

submodule: avoid auto-discovery in prepare_submodule_repo_env()
The function is used to set up the environment variable used in a
subprocess we spawn in a submodule directory. The callers set up a
child_process structure, find the working tree path of one submodule
and set .dir field to it, and then use start_command() API to spawn
the subprocess like "status", "fetch", etc.
When this happens, we expect that the ".git" (either a directory or
a gitfile that points at the real location) in the current working
directory of the subprocess MUST be the repository for the submodule.
If this ".git" thing is a corrupt repository, however, because
prepare_submodule_repo_env() unsets GIT_DIR and GIT_WORK_TREE, the
subprocess will see ".git", thinks it is not a repository, and
attempt to find one by going up, likely to end up in finding the
repository of the superproject. In some codepaths, this will cause
a command run with the "--recurse-submodules" option to recurse
forever.
By exporting GIT_DIR=.git, disable the auto-discovery logic in the
subprocess, which would instead stop it and report an error.
The test illustrates existing problems in a few callsites of this
function. Without this fix, "git fetch --recurse-submodules", "git
status" and "git diff" keep recursing forever.

allow do_submodule_path to work even if submodule isn't checked out
Currently, do_submodule_path will attempt locating the .git directory by
using read_gitfile on <path>/.git. If this fails it just assumes the
<path>/.git is actually a git directory.
This is good because it allows for handling submodules which were cloned
in a regular manner first before being added to the superproject.
Unfortunately this fails if the <path> is not actually checked out any
longer, such as by removing the directory.
Fix this by checking if the directory we found is actually a gitdir. In
the case it is not, attempt to lookup the submodule configuration and
find the name of where it is stored in the .git/modules/ directory of
the superproject.
If we can't locate the submodule configuration, this might occur because
for example a submodule gitlink was added but the corresponding
.gitmodules file was not properly updated. A die() here would not be
pleasant to the users of submodule diff formats, so instead, modify
do_submodule_path() to return an error code:
- git_pathdup_submodule() returns NULL when we fail to find a path.
- strbuf_git_path_submodule() propagates the error code to the caller.
Modify the callers of these functions to check the error code and fail
properly. This ensures we don't attempt to use a bad path that doesn't
match the corresponding submodule.
Because this change fixes add_submodule_odb() to work even if the
submodule is not checked out, update the wording of the submodule log
diff format to correctly display that the submodule is "not initialized"
instead of "not checked out"
Add tests to ensure this change works as expected.

Add an extension to git-diff and git-log (and any other graph-aware

"diff/log --stat" has a logic that determines the display columns

added the output_prefix_length field to diff_options structure to
allow this logic to subtract the display columns used for the
history graph part from the total "terminal width"; this matters
when the "git log --graph -p" option is in use.
The field must be set to the number of display columns needed to
show the output from the output_prefix() callback, which is error
prone. As there is only one user of the field, and the user has the
actual value of the prefix string, let's get rid of the field and
have the user count the display width itself.

Compiling color.c with gcc 6.2.0 using -O3 produces some
-Wmaybe-uninitialized false positives:
color.c: In function ‘color_parse_mem’:

out += xsnprintf(out, len, "%c8;2;%d;%d;%d", type,

color.c:208:15: note: ‘bg.blue’ was declared here
struct color bg = { COLOR_UNSPECIFIED };
^~
[ditto for bg.green, bg.red, fg.blue, etc]
This is doubly confusing, because the declaration shows it
being initialized! Even though we do not explicitly
initialize the color components, an incomplete initializer
sets the unmentioned members to zero.
What the warning doesn't show is that we later do this:
struct color c;
if (!parse_color(&c, ...)) {
if (fg.type == COLOR_UNSPECIFIED)
fg = c;
...
}
gcc is clever enough to realize that a struct assignment
from an uninitialized variable taints the destination. But
unfortunately it's _not_ clever enough to realize that we
only look at those members when type is set to COLOR_RGB, in
which case they are always initialized.
With -O2, gcc does not look into parse_color() and must
assume that "c" emerges fully initialized. With -O3, it
inlines parse_color(), and learns just enough to get
confused.
We can silence the false positive by initializing the
temporary "c". This also future-proofs us against
violating the type assumptions (the result would probably
still be buggy, but in a deterministic way).

error_errno: use constant return similar to error()
Commit e208f9c (make error()'s constant return value more

error_errno(), losing the magic from e208f9c for those
sites.

with gcc 6.2.0). Let's give error_errno() the same

The algorithm in diff-highlight only understands how to look
at two sides of a diff; it cannot correctly handle combined
diffs with multiple preimages. Often highlighting does not
trigger at all for these diffs because the line counts do
not match up. E.g., if we see:
- ours
-theirs
++resolved
we would not bother highlighting; it naively looks like a
single line went away, and then a separate hunk added
another single line.
But of course there are exceptions. E.g., if the other side
deleted the line, we might see:
- ours
++resolved
which looks like we dropped " ours" and added "+resolved".
This is only a small highlighting glitch (we highlight the
space and the "+" along with the content), but it's also the
tip of the iceberg. Even if we learned to find the true
content here (by noticing we are in a 3-way combined diff
and marking _two_ characters from the front of the line as
uninteresting), there are other more complicated cases where
we really do need to handle a 3-way hunk.
Let's just punt for now; we can recognize combined diffs by
the presence of extra "@" symbols in the hunk header, and
treat them as non-diff content.

By splitting the part that reads from a file and the part that
parses the variable definitions from the contents, make the latter
can be more reusable in the future.
Each test run generates a "count" file in t/test-results
that stores the number of successful, failed, etc tests.
If you run "t1234-foo.sh", that file is named as
"t/test-results/t1234-foo-$$.count"
The addition of the PID there is serving no purpose, and
makes analysis of the count files harder.
The presence of the PID dates back to 2d84e9f (Modify
test-lib.sh to output stats to t/test-results/*,
2008-06-08), but no reasoning is given there. Looking at the
current code, we can see that other files we write to
test-results (like *.exit and *.out) do _not_ have the PID
included. So the presence of the PID does not meaningfully
allow one to store the results from multiple runs anyway.
Moreover, anybody wishing to read the *.count files to
aggregate results has to deal with the presence of multiple
files for a given test (and figure out which one is the most
recent based on their timestamps!). The only consumer of
these files is the aggregate.sh script, which arguably gets
this wrong. If a test is run multiple times, its counts will
appear multiple times in the total (I say arguably only
because the desired semantics aren't documented anywhere,
but I have trouble seeing how this behavior could be
useful).
So let's just drop the PID, which fixes aggregate.sh, and
will make new features based around the count files easier
to write.
Note that since the count-file may already exist (when
re-running a test), we also switch the "cat" from appending
to truncating. The use of append here was pointless in the
first place, as we expected to always write to a unique file.

existing.

Instead of dying there, let the caller high up in the callchain notice
the error and handle it (by dying, still).
The function sequencer_pick_revisions() has only two callers,
cmd_revert() and cmd_cherry_pick(), both of which check the return
value and react appropriately upon errors.
So this is a safe conversion to make sequencer_pick_revisions()
callable from new callers that want it not to die, without changing
the external behaviour of anything existing.

Since 3b75ee9 ("blame: allow to blame paths freshly added to the index",
2016-07-16) git blame also looks at the index to determine if there is a
file that was freshly added to the index.
cache_name_pos returns -pos - 1 in case there is no match is found, or
if the name matches, but the entry has a stage other than 0. As git
blame should work for unmerged files, it uses strcmp to determine
whether the name of the returned position matches, in which case the
file exists, but is merely unmerged, or if the file actually doesn't
exist in the index.
If the repository is empty, or if the file would lexicographically be
sorted as the last file in the repository, -cache_name_pos - 1 is
outside of the length of the active_cache array, causing git blame to
segfault. Guard against that, and die() normally to restore the old
behaviour.

SubmittingPatches: use gitk's "Copy commit summary" format
Update the suggestion in 175d38ca ("SubmittingPatches: document how
to reference previous commits", 2016-07-28) on the format to refer
to a commit to match what gitk has been giving since last year with
its "Copy commit summary" command; also mention this as one of the
ways to obtain a commit reference in this format.

The recent i18n patch we added during this cycle did a bit too much
refactoring of the messages to avoid word-legos; the repetition has
been reduced to help translators.
* ja/i18n:
i18n: simplify numeric error reporting
i18n: fix git rebase interactive commit messages
i18n: fix typos for translation
The tempfile (hence its user lockfile) API lets the caller to open
a file descriptor to a temporary file, write into it and then
finalize it by first closing the filehandle and then either
removing or renaming the temporary file. When the process spawns a
subprocess after obtaining the file descriptor, and if the
subprocess has not exited when the attempt to remove or rename is
made, the last step fails on Windows, because the subprocess has
the file descriptor still open. Open tempfile with O_CLOEXEC flag
to avoid this (on Windows, this is mapped to O_NOINHERIT).
* bw/mingw-avoid-inheriting-fd-to-lockfile:
mingw: ensure temporary file handles are not inherited by child processes
t6026-merge-attr: child processes must not inherit index.lock handles
The "git -c var[=val] cmd" facility to append a configuration
variable definition at the end of the search order was described in
git(1) manual page, but not in git-config(1), which was more likely
place for people to look for when they ask "can I make a one-shot
override, and if so how?"
* dg/document-git-c-in-git-config-doc:
doc: mention `git -c` in git-config(1)
git ls-files: text=auto eol=lf is supported in Git 2.10
The man page for `git ls-files --eol` mentions the combination
of text attributes "text=auto eol=lf" or "text=auto eol=crlf" as not
supported yet, but may be in the future.
Now they are supported.

receive-pack: allow a maximum input size to be specified
Receive-pack feeds its input to either index-pack or
unpack-objects, which will happily accept as many bytes as
a sender is willing to provide. Let's allow an arbitrary
cutoff point where we will stop writing bytes to disk.
Cleaning up what has already been written to disk is a
related problem that is not addressed by this patch.

format-patch: show 0/1 and 1/1 for singleton patch with cover letter
Change the default behavior of git-format-patch to generate numbered
sequence of 0/1 and 1/1 when generating both a cover-letter and a single
patch. This standardizes the cover letter to have 0/N which helps
distinguish the cover letter from the patch itself. Since the behavior
is easily changed via configuration as well as the use of -n and -N this
should be acceptable default behavior.
Add tests for the new default behavior.
