Jonathan Nieder 6a143aa2b2 checkout -m: attempt merge when deletion of path was staged
twoway_merge() is missing an o->gently check in the case where a file
that needs to be modified is missing from the index but present in the
old and new trees.  As a result, in this case 'git checkout -m' errors
out instead of trying to perform a merge.

Fix it by checking o->gently.  While at it, inline the o->gently check
into reject_merge to prevent future call sites from making the same
mistake.

Noticed by code inspection.  The test for the motivating case was
added by JC.

Jeff King e09867f060 intersect_paths: respect mode in git's tree-sort
When we do a combined diff, we individually diff against
each parent, and then use intersect_paths to do a parallel
walk through the sorted results and come up with a final
list of interesting paths.

The sort order here is that returned by the diffs, which
means it is in git's tree-order which sorts sub-trees as if
their paths have "/" at the end. When we do our parallel
walk, we need to use a comparison function which provides
the same order.

Since 8518ff8 (combine-diff: optimize combine_diff_path sets
intersection, 2014-01-20), we use a simple strcmp to
compare the pathnames, and get this wrong. It's somewhat
hard to trigger because normally a diff does not produce
tree entries at all, and therefore the sort order is the
same as a strcmp. However, if the "-t" option is used with
the diff, then we will produce diff_filepairs for both trees
and files.

We can use base_name_compare to do the comparison, just as
the tree-diff code does. Even though what we have are not
technically base names (they are full paths within the
tree), the end result is the same (we do not care about
interior slashes at all, only about the final character).

However, since we do not have the length of each path
stored, we take a slight shortcut: if neither of the entries
is a sub-tree then the comparison is equivalent to a strcmp.
This lets us skip the extra strlen calls in the common case
without having to reimplement base_name_compare from
scratch.

Johannes Sixt 41ca19b6a6 tests: fix negated test_i18ngrep calls
The helper function test_i18ngrep pretends that it found the expected
results when it is running under GETTEXT_POISON. For this reason, it must
not be used negated like so

   ! test_i18ngrep foo bar

because the test case would fail under GETTEXT_POISON. The function offers
a special syntax to test that a pattern is *not* found:

   test_i18ngrep ! foo bar

Convert incorrect uses to this syntax.

Jeff King f7f91086a3 pack-objects: turn off bitmaps when we see --shallow lines
Reachability bitmaps do not work with shallow operations,
because they cache a view of the object reachability that
represents the true objects. Whereas a shallow repository
(or a shallow operation in a repository) is inherently
cutting off the object graph with a graft.

We explicitly disallow the use of bitmaps in shallow
repositories by checking is_repository_shallow(), and we
should continue to do that. However, we also want to
disallow bitmaps when we are serving a fetch to a shallow
client, since we momentarily take on their grafted view of
the world.

It used to be enough to call is_repository_shallow at the
start of pack-objects.  Upload-pack wrote the other side's
shallow state to a temporary file and pointed the whole
pack-objects process at this state with "git --shallow-file",
and from the perspective of pack-objects, we really were
in a shallow repo.  But since b790e0f (upload-pack: send
shallow info over stdin to pack-objects, 2014-03-11), we do
it differently: we send --shallow lines to pack-objects over
stdin, and it registers them itself.

This means that our is_repository_shallow check is way too
early (we have not been told about the shallowness yet), and
that it is insufficient (calling is_repository_shallow is
not enough, as the shallow grafts we register do not change
its return value). Instead, we can just turn off bitmaps
explicitly when we see these lines.

Lukas Fleischer 2c8544ab91 bundle: fix exclusion of annotated tags
In commit c9a42c4 (bundle: allow rev-list options to exclude annotated
tags, 2009-01-02), support for excluding annotated tags outside the
specified date range was added. However, the wrong order of parameters
was chosen when calling memchr().

Fix this by swapping the character to search for with the maximum length
parameter.  Also cover this behavior with an additional test.

Junio C Hamano 477a08af04 apply: omit ws check for excluded paths
Whitespace breakages are checked while the patch is being parsed.
Disable them at the beginning of parse_chunk(), where each
individual patch is parsed, immediately after we learn the name of
the file the patch applies to and before we start parsing the diff
contained in the patch.

One may naively think that we should be able to not just skip the
whitespace checks but simply fast-forward to the next patch without
doing anything once use_patch() tells us that this patch is not
going to be used.  But in reality we cannot really skip much of the
parsing in order to do such a "fast-forward", primarily because
parsing "@@ -k,l +m,n @@" lines and counting the input lines is how
we determine the boundaries of individual patches.

Junio C Hamano d487b0ba50 apply: use the right attribute for paths in non-Git patches
We parse each patchfile and find the name of the path the patch
applies to, and then use that name to consult the attribute system
to find the whitespace rules to be used, and also the target file
(either in the working tree or in the index) to replay the changes
against.

Unlike a Git-generated patch, a non-Git patch is taken to have the
pathnames relative to the current working directory.  The names
found in such a patch are modified by prepending the prefix by the
prefix_patches() helper function introduced in 56185f49 (git-apply:
require -p<n> when working in a subdirectory., 2007-02-19).

However, this prefixing is done after the patch is fully parsed and
affects only what target files are patched.  Because the attributes
are checked against the names found in the patch during the parsing,
not against the final pathname, the whitespace check that is done
during parsing ends up using attributes for a wrong path for non-Git
patches.

Fix this by doing the prefix much earlier, immediately after the
header part of each patch is parsed and we learn the name of the
path the patch affects.

Junio C Hamano a789ca70e7 config: teach "git -c" to recognize an empty string
In a config file, you can do:

  [foo]
  bar

to turn the "foo.bar" boolean flag on, and you can do:

  [foo]
  bar=

to set "foo.bar" to the empty string. However, git's "-c"
parameter treats both:

  git -c foo.bar

and

  git -c foo.bar=

as the boolean flag, and there is no way to set a variable
to the empty string. This patch enables the latter form to
do that.

Karsten Blees e8d08871c9 t800[12]: work around MSys limitation
MSys works very hard to convert Unix-style paths into DOS-style ones.
*Very* hard.

So hard, indeed, that

	git blame -L/hello/,/green/

is translated into something like

	git blame -LC:/msysgit/hello/,C:/msysgit/green/

As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line
3204ff:

	case '-':
	  //
	  // here we check for POSIX paths as attributes to a POSIX switch.
	  //
	...

seemingly absolute POSIX paths in single-letter options get expanded by
msys.dll unless they contain '=' or ';'.

So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign
works only when it is before a comma, so in the above example, /=*green/
would still be converted to a DOS-style path.)

The -L mangling can be done by the script, just before the parameter is
passed to the executable.  This version does not modify the body of the
tests and is active on MinGW only.

Karsten Blees 32f4cb6cee MinGW: disable legacy encoding tests
On Windows, all native APIs are Unicode-based. It is impossible to pass
legacy encoded byte arrays to a process via command line or environment
variables. Disable the tests that try to do so.

In t3901, most tests still work if we don't mess up the repository encoding
in setup, so don't switch to ISO-8859-1 on MinGW.

Note that i18n tests that do their encoding tricks via encoded files (such
as t3900) are not affected by this.
