On Windows, there is no SIGPIPE. A consequence of this is that the
upstream process of a pipe does not notice the death of the downstream
process until the pipe buffer is full and writing more data returns an
error. This behavior is the reason for an annoying delay during the
execution of t7610-mergetool.sh: There are a number of test cases where
'yes' is invoked upstream. Since the utility is basically an endless
loop it runs, on Windows, until the pipe buffer is full. This does take
a few seconds.
The test suite has its own implementation of 'yes'. Modify it to produce
only a limited amount of output that is sufficient for the test suite.
The amount chosen should be sufficiently high for any test case, assuming
that future test cases will not exaggerate their demands of input from
an upstream 'yes' invocation.

When merging files with CR/LF line endings, the conflict markers should
match those, lest the output file has mixed line endings.
This is particularly of interest on Windows, where some editors get
*really* confused by mixed line endings.
The original version of this patch by Beat Bolli respected core.eol, and
a subsequent improvement by this developer also respected gitattributes.
This approach was suboptimal, though: `git merge-file` was invented as a
drop-in replacement for GNU merge and as such has no problem operating
outside of any repository at all!
Another problem with the original approach was pointed out by Junio
Hamano: legacy repositories might have their text files committed using
CR/LF line endings (and core.eol and the gitattributes would give us a
false impression there). Therefore, the much superior approach is to
simply match the context's line endings, if any.
We actually do not have to look at the *entire* context at all: if the
files are all LF-only, or if they all have CR/LF line endings, it is
sufficient to look at just a *single* line to match that style. And if
the line endings are mixed anyway, it is *still* okay to imitate just a
single line's eol: we will just add to the pile of mixed line endings,
and there is nothing we can do about that.
So what we do is: we look at the line preceding the conflict, falling
back to the line preceding that in case it was the last line and had no
line ending, falling back to the first line, first in the first
post-image, then the second post-image, and finally the pre-image.
If we find consistent CR/LF (or undecided) end-of-line style, we match
that, otherwise we use LF-only line endings for the conflict markers.
Note that while it is true that there have to be at least two lines we
can look at (otherwise there would be no conflict), the same is not true
for line *endings*: the three files in question could all consist of a
single line without any line ending, each. In this case we fall back to
using LF-only.

Since b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-07-11),
git-tag has started showing tags with ambiguous names (i.e.,
when both "heads/foo" and "tags/foo" exists) as "tags/foo"
instead of just "foo". This is both:
- pointless; the output of "git tag" includes only
refs/tags, so we know that "foo" means the one in
"refs/tags".
and
- ambiguous; in the original output, we know that the line
"foo" means that "refs/tags/foo" exists. In the new
output, it is unclear whether we mean "refs/tags/foo" or
"refs/tags/tags/foo".
The reason this happens is that commit b7cc53e9 switched
git-tag to use ref-filter's "%(refname:short)" output
formatting, which was adapted from for-each-ref. This more
general code does not know that we care only about tags, and
uses shorten_unambiguous_ref to get the short-name. We need
to tell it that we care only about "refs/tags/", and it
should shorten with respect to that value.
In theory, the ref-filter code could figure this out by us
passing FILTER_REFS_TAGS. But there are two complications
there:
1. The handling of refname:short is deep in formatting
code that does not even have our ref_filter struct, let
alone the arguments to the filter_ref struct.
2. In git v2.7.0, we expose the formatting language to the
user. If we follow this path, it will mean that
"%(refname:short)" behaves differently for "tag" versus
"for-each-ref" (including "for-each-ref refs/tags/"),
which can lead to confusion.
Instead, let's add a new modifier to the formatting
language, "strip", to remove a specific set of prefix
components. This fixes "git tag", and lets users invoke the
same behavior from their own custom formats (for "tag" or
"for-each-ref") while leaving ":short" with its same
consistent meaning in all places.
We introduce a test in t7004 for "git tag", which fails
without this patch. We also add a similar test in t3203 for
"git branch", which does not actually fail. But since it is
likely that "branch" will eventually use the same formatting
code, the test helps defend against future regressions.

When we want to look up a submodule ref, we use
get_ref_cache(path) to find or auto-create its ref cache.
But if we feed a path that isn't actually a git repository,
we blindly create the ref cache, and then may die deeper in
the code when we try to access it. This is a problem because
many callers speculatively feed us a path that looks vaguely
like a repository, and expect us to tell them when it is
not.
This patch teaches resolve_gitlink_ref to reject
non-repository paths without creating a ref_cache. This
avoids the die(), and also performs better if you have a
large number of these faux-submodule directories (because
the ref_cache lookup is linear, under the assumption that
there won't be a large number of submodules).
To accomplish this, we also break get_ref_cache into two
pieces: the lookup and auto-creation (the latter is lumped
into create_ref_cache). This lets us first cheaply ask our
cache "is it a submodule we know about?" If so, we can avoid
repeating our filesystem lookup. So lookups of real
submodules are not penalized; they examine the submodule's
.git directory only once.
The test in t3000 demonstrates a case where this improves
correctness (we used to just die). The new perf case in
p7300 shows off the speed improvement in an admittedly
pathological repository:

Commit 348d4f2 (filter-branch: skip index read/write when
possible, 2015-11-06) taught filter-branch to optimize out
the final "git write-tree" when we know we haven't touched
the tree with any of our filters. It does by simply putting
the literal text "$commit^{tree}" into the "$tree" variable,
avoiding a useless rev-parse call.
However, when we pass this to git_commit_non_empty_tree(),
it gets confused; it resolves "$commit^{tree}" itself, and
compares our string to the 40-hex sha1, which obviously
doesn't match. As a result, "--prune-empty" (or any custom
filter using git_commit_non_empty_tree) will fail to drop
an empty commit (when filter-branch is used without a tree
or index filter).
Let's resolve $tree to the 40-hex ourselves, so that
git_commit_non_empty_tree can work. Unfortunately, this is a
bit slower due to the extra process overhead:
$ cd t/perf && ./run 348d4f2 HEAD p7000-filter-branch.sh
[...]
Test 348d4f2 HEAD
--------------------------------------------------------------
7000.2: noop filter 3.76(0.24+0.26) 4.54(0.28+0.24) +20.7%
We could try to make git_commit_non_empty_tree more clever.
However, the value of $tree here is technically
user-visible. The user can provide arbitrary shell code at
this stage, which could itself have a similar assumption to
what is in git_commit_non_empty_tree. So the conservative
choice to fix this regression is to take the 20% hit and
give the pre-348d4f2 behavior. We still end up much faster
than before the optimization:
$ cd t/perf && ./run 348d4f2^ HEAD p7000-filter-branch.sh
[...]
Test 348d4f2^ HEAD
--------------------------------------------------------------
7000.2: noop filter 9.51(4.32+0.40) 4.51(0.28+0.23) -52.6%

git reflog (ab)uses the log machinery to display its list of log
entries. To do so it must fake commit parent information for the log
walker.
For refs in refs/heads this is no problem, as they should only ever
point to commits. Tags and other refs however can point to anything,
thus their reflog may contain non-commit objects.
To avoid segfaulting, we check whether reflog entries are commits before
feeding them to the log walker and skip any non-commits. This means that
git reflog output will be incomplete for such refs, but that's one step
up from segfaulting. A more complete solution would be to decouple git
reflog from the log walker machinery.

'git replace --edit' should error out when the invoked editor fails,
but the test checking this behavior would not notice if this weren't
the case.
The test in question, ever since it was added in 85f98fc037
(replace: add tests for --edit, 2014-05-17), has simulated a failing
editor in an unconventional way:
test_must_fail env GIT_EDITOR='./fakeeditor;false' git replace --edit
I presume the reason for this unconventional editor was the fact that
'git replace --edit' requires the edited object to be different from
the original, but a mere 'false' as editor would leave the object
unchanged and 'git replace --edit' would error out anyway complaining
about the new and the original object files being the same. Running
'fakeeditor' before 'false' was supposed to ensure that the object
file is modified and thus 'git replace --edit' errors out because of
the failed editor.
However, this editor doesn't actually modify the edited object,
because start_command() turns this editor into:
/bin/sh -c './fakeeditor;false "$@"' './fakeeditor;false' \
'.../.git/REPLACE_EDITOBJ'
This means that the test's fakeeditor script doesn't even get the path
of the object to be edited as argument, triggering error messages from
the commands executed inside the script ('sed' and 'mv'), and
ultimately leaving the object file unchanged.
If a patch were to remove the die() from the error path after
launch_editor(), the test would not catch it, because 'git replace'
would continue execution past launch_editor() and would error out a
bit later due to the unchanged edited object. Though 'git replace'
would error out for the wrong reason, this would satisfy
'test_must_fail' just as well, and the test would succeed leaving the
undesired change unnoticed.
Create a proper failing fake editor script for this test to ensure
that the edited object is in fact modified and 'git replace --edit'
won't error out because the new and original object files are the
same.

When we unwrap a tag to find its commit for a traversal, we
do not propagate the "name" field of the tag in the pending
array (i.e., the ref name the user gave us in the first
place) to the commit (instead, we use an empty string). This
means that "git log --source" will never show the tag-name
for commits we reach through it.
This was broken in 2073949 (traverse_commit_list: support
pending blobs/trees with paths, 2014-10-15). That commit
tried to be careful and avoid propagating the path
information for a tag (which would be nonsensical) to trees
and blobs. But it should not have cut off the "name" field,
which should carry forward to children.
Note that this does mean that the "name" field will carry
forward to blobs and trees, too. Whereas prior to 2073949,
we always gave them an empty string. This is the right thing
to do, but in practice no callers probably use it (since now
we have an explicit separate "path" field, which was the
point of 2073949).
We add tests here not only for the broken case, but also a
basic sanity test of "log --source" in general, which did
not have any coverage in the test suite.

If the user explicitly specified a merge strategy or strategy
options, continue to use that strategy/option after
"rebase --continue". Add a test of the corrected behavior.
If --merge is specified or implied by -s or -X, then "strategy and
"strategy_opts" are set to values from which "strategy_args" can be
derived; otherwise they are set to empty strings. Either way,
their values are propagated from one step of an interactive rebase
to the next via state files.
"do_merge", on the other hand, is *not* propagated to later steps of
an interactive rebase. Therefore, making the initialization of
"strategy_args" conditional on "do_merge" being set prevents later
steps of an interactive rebase from setting it correctly.
Luckily, we don't need the "do_merge" guard at all. If the rebase
was started without --merge, then "strategy" and "strategy_opts"
are both the empty string, which results in "strategy_args" also
being set to the empty string, which is just what we want in that
situation. So remove the "do_merge" guard and derive
"strategy_args" from "strategy" and "strategy_opts" every time.
