simplify-merges: drop merge from irrelevant side branch
Reimplement commit
4b7f53da on top of the new simplify-merges
infrastructure, tightening the condition to only consider root parents;
the original version incorrectly dropped parents that were TREESAME to
anything.
Original log message follows.
The merge simplification rule stated in
6546b59 (revision traversal:
show full history with merge simplification, 2008-07-31) still
treated merge commits too specially. Namely, in a history with this
shape:
---o---o---M
/
x---x---x
where three 'x' were on a history completely unrelated to the main
history 'o' and do not touch any of the paths we are following, we
still said that after simplifying all of the parents of M, 'x'
(which is the leftmost 'x' that rightmost 'x simplifies down to) and
'o' (which would be the last commit on the main history that touches
the paths we are following) are independent from each other, and
both need to be kept.
That is incorrect; when the side branch 'x' never touches the paths,
it should be removed to allow M to simplify down to the last commit
on the main history that touches the paths.

revision.c: Make --full-history consider more merges
History simplification previously always treated merges as TREESAME
if they were TREESAME to any parent.
While this was consistent with the default behaviour, this could be
extremely unhelpful when searching detailed history, and could not be
overridden. For example, if a merge had ignored a change, as if by "-s
ours", then:
git log -m -p --full-history -Schange file
would successfully locate "change"'s addition but would not locate the
merge that resolved against it.
Futher, simplify_merges could drop the actual parent that a commit
was TREESAME to, leaving it as a normal commit marked TREESAME that
isn't actually TREESAME to its remaining parent.
Now redefine a commit's TREESAME flag to be true only if a commit is
TREESAME to _all_ of its parents. This doesn't affect either the default
simplify_history behaviour (because partially TREESAME merges are turned
into normal commits), or full-history with parent rewriting (because all
merges are output). But it does affect other modes. The clearest
difference is that --full-history will show more merges - sufficient to
ensure that -m -p --full-history log searches can really explain every
change to the file, including those changes' ultimate fate in merges.
Also modify simplify_merges to recalculate TREESAME after removing
a parent. This is achieved by storing per-parent TREESAME flags on the
initial scan, so the combined flag can be easily recomputed.
This fixes some t6111 failures, but creates a couple of new ones -
we are now showing some merges that don't need to be shown.

combine-diff.c: Fix output when changes are exactly 3 lines apart
When a deletion is followed by exactly 3 (or whatever the number of
context lines) unchanged lines, followed by another change, the combined
diff output would hide the first deletion, resulting in a malformed
diff.
This happened because the 3 lines before each change are painted
interesting, but also marked as no_pre_delete to prevent showing deletes
that were previously marked as uninteresting. This behaviour was
introduced in
c86fbe53 (diff -c/--cc: do not include uninteresting
deletion before leading context). However, as a side effect, this could
also mark deletes that were already interesting as no_pre_delete. This
would happen only if the delete was exactly 3 lines away from the next
change, since lines farther away would not be touched by the "paint
three lines before the change" code and lines closer would be painted
by the "merge two adjacent hunks" code instead, which does not set the
no_pre_delete flag.

them because neither source files nor build flags have changed. (This
remained hidden for so long most likely because any other intervening
use of 'make' will change the build flags, causing a full rebuild.)
So we make an exception for *.gcno. The *.gcda are the coverage
results, written when the gcov-instrumented program is run. We still
remove those, so as to get a one-test-run view of the data; you could
probably argue the other way too.

fetch: opportunistically update tracking refs
When we run a regular "git fetch" without arguments, we
update the tracking refs according to the configured
refspec. However, when we run "git fetch origin master" (or
"git pull origin master"), we do not look at the configured
refspecs at all, and just update FETCH_HEAD.
We miss an opportunity to update "refs/remotes/origin/master"

confusing, because they would want to do further comparisons
against the old state of the remote master, like:
$ git pull origin master
$ git log HEAD...origin/master

commit happened to be in origin/master from the last time
they did a complete "git fetch". This patch will update a
ref from the RHS of a configured refspec whenever we happen

t5004: avoid using tar for checking emptiness of archive
Test 2 of t5004 checks if a supposedly empty tar archive really
contains no files.
24676f02 (t5004: fix issue with empty archive test
and bsdtar) removed our commit hash to make it work with bsdtar, but
the test still fails on NetBSD and OpenBSD, which use their own tar
that considers a tar file containing only NULs as broken.
Here's what the different archivers do when asked to create a tar
file without entries:
$ uname -v
NetBSD 6.0.1 (GENERIC)
$ gtar --version | head -1
tar (GNU tar) 1.26
$ bsdtar --version
bsdtar 2.8.4 - libarchive 2.8.4
$ : >zero.tar
$ perl -e 'print "\0" x 10240' >tenk.tar
$ sha1 zero.tar tenk.tar
SHA1 (zero.tar) =
da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA1 (tenk.tar) =
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | tar cf - -T - | sha1
da39a3ee5e6b4b0d3255bfef95601890afd80709
$ : | gtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | bsdtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
So NetBSD's native tar creates an empty file, while GNU tar and bsdtar
both give us 10KB of NULs -- just like git archive with an empty tree.
Now let's see how the archivers handle these two kinds of empty tar
files:
$ tar tf zero.tar; echo $?
tar: Unexpected EOF on archive file
1
$ gtar tf zero.tar; echo $?
gtar: This does not look like a tar archive
gtar: Exiting with failure status due to previous errors
2
$ bsdtar tf zero.tar; echo $?
0
$ tar tf tenk.tar; echo $?
tar: Cannot identify format. Searching...
tar: End of archive volume 1 reached
tar: Sorry, unable to determine archive format.
1
$ gtar tf tenk.tar; echo $?
0
$ bsdtar tf tenk.tar; echo $?
0
NetBSD's tar complains about both, bsdtar happily accepts any of them
and GNU tar doesn't like zero-length archive files. So the safest
course of action is to stay with our block-of-NULs format which is
compatible with GNU tar and bsdtar, as we can't make NetBSD's native
tar happy anyway.
We can simplify our test, however, by taking tar out of the picture.
Instead of extracting the archive and checking for the non-presence of
files, check if the file has a size of 10KB and contains only NULs.
This makes t5004 pass on NetBSD and OpenBSD.

t5004: resurrect original empty tar archive test
Add a test to verify the emptiness of an archive by extracting its
contents. Don't run this test if the version of tar doesn't support
archives containing only a comment header, though.
The existing check 'tar archive of empty tree is empty' used to work
like that (minus the tar capability check) but was changed to depend
on the exact representation of empty tar files created by git archive
instead of on the behaviour of tar in order to avoid issues with
different tar versions.
The different approaches test different things: The existing one is
for empty trees, for which we know the exact expected output and thus
we can simply check it without extracting; the new one is for commits
with empty trees, whose archives include stamps and so the more
"natural" check by extraction is a better fit because it focuses on
the interesting aspect, namely the absence of any archive entries.

24676f02 (t5004: fix issue with empty archive test
and bsdtar) removed our commit hash to make it work with bsdtar, but
the test still fails on NetBSD and OpenBSD, which use their own tar
that considers a tar file containing only NULs as broken.
Here's what the different archivers do when asked to create a tar
file without entries:
$ uname -v
NetBSD 6.0.1 (GENERIC)
$ gtar --version | head -1
tar (GNU tar) 1.26
$ bsdtar --version
bsdtar 2.8.4 - libarchive 2.8.4
$ : >zero.tar
$ perl -e 'print "\0" x 10240' >tenk.tar
$ sha1 zero.tar tenk.tar
SHA1 (zero.tar) =
da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA1 (tenk.tar) =
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | tar cf - -T - | sha1
da39a3ee5e6b4b0d3255bfef95601890afd80709
$ : | gtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | bsdtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
So NetBSD's native tar creates an empty file, while GNU tar and bsdtar
both give us 10KB of NULs -- just like git archive with an empty tree.
Now let's see how the archivers handle these two kinds of empty tar
files:
$ tar tf zero.tar; echo $?
tar: Unexpected EOF on archive file
1
$ gtar tf zero.tar; echo $?
gtar: This does not look like a tar archive
gtar: Exiting with failure status due to previous errors
2
$ bsdtar tf zero.tar; echo $?
0
$ tar tf tenk.tar; echo $?
tar: Cannot identify format. Searching...
tar: End of archive volume 1 reached
tar: Sorry, unable to determine archive format.
$ gtar tf tenk.tar; echo $?
0
$ bsdtar tf tenk.tar; echo $?
0
NetBSD's tar complains about both, bsdtar happily accepts any of them
and GNU tar doesn't like zero-length archive files. So the safest
course of action is to stay with our block-of-NULs format which is
compatible with GNU tar and bsdtar, as we can't make NetBSD's native
tar happy anyway.
We can simplify our test, however, by taking tar out of the picture.
Instead of extracting the archive and checking for the non-presence of
files, check if the file has a size of 10KB and contains only NULs.
This makes t5004 pass on NetBSD and OpenBSD.

t5004: ignore pax global header file
Versions of tar that don't know pax headers -- like the ones in NetBSD 6
and OpenBSD 5.2 -- extract them as regular files. Explicitly ignore the
file created for our global header when checking the list of extracted
files, as this is normal and harmless fall-back behaviour. This fixes
test 3 of t5004 on these platforms.

git-svn: added an --include-path flag
The SVN::Fetcher module is now able to filter for inclusion as well
as exclusion (as used by --ignore-path). Also added tests, documentation
changes and git completion script.
If you have an SVN repository with many top level directories and you
only want a git-svn clone of some of them then using --ignore-path is
difficult as it requires a very long regexp. In this case it's much
easier to filter for inclusion.

cygwin: Remove the CYGWIN_V15_WIN32API build variable
Commit
380a4d92 ("Update cygwin.c for new mingw-64 win32 api headers",
11-11-2012) solved an header include order problem on cygwin 1.7 when
using the new mingw-64 WIN32 API headers. The solution involved using
a new build variable (V15_MINGW_HEADERS) to conditionally compile the
cygwin.c source file to use an include order appropriate for the old
and new header files. (The build variable was later renamed in commit
9fca6cff to CYGWIN_V15_WIN32API).
The include order used for cygwin 1.7 includes the "win32.h" header
before "../git-compat-util.h". This order was problematic on cygwin
1.5, since it lead to the WIN32 symbol being defined along with the
inclusion of some WIN32 API headers (e.g. <winsock2.h>) which cause
compilation errors.
The header include order problem on cygwin 1.5 has since been fixed
(see commit "mingw: rename WIN32 cpp macro to GIT_WINDOWS_NATIVE"),
so we can now remove the conditional compilation along with the
associated CYGWIN_V15_WIN32API build variable.
