5f4e02e517 MinGW: update tests to handle a native eol of crlf
Some of the tests were written with the assumption that the native
eol would always be lf. After defining NATIVE_CRLF on MinGW, these
tests began failing.  This change will update the tests to also
handle a native eol of crlf.

5491e9e29e Makefile: propagate NATIVE_CRLF to C
Commit 95f31e9a (convert: The native line-ending is \r\n on MinGW,
2010-09-04) correctly points out that the NATIVE_CRLF setting is
incorrectly set on Mingw git. However, the Makefile variable is not
propagated to the C preprocessor and results in no change. This patch
pushes the definition to the C code and adds a test to validate that
when core.eol as native is crlf, we actually normalize text files to
this line ending convention when core.autocrlf is false.

466fb6742d pretty: provide a strict ISO 8601 date format
Git's "ISO" date format does not really conform to the ISO 8601
standard due to small differences, and it cannot be parsed by ISO
8601-only parsers, e.g. those of XML toolchains.

The output from "--date=iso" deviates from ISO 8601 in these ways:

  - a space instead of the `T` date/time delimiter
  - a space between time and time zone
  - no colon between hours and minutes of the time zone

Add a strict ISO 8601 date format for displaying committer and
author dates.  Use the '%aI' and '%cI' format specifiers and add
'--date=iso-strict' or '--date=iso8601-strict' date format names.

a872275098 teach fast-export an --anonymize option
Sometimes users want to report a bug they experience on
their repository, but they are not at liberty to share the
contents of the repository. It would be useful if they could
produce a repository that has a similar shape to its history
and tree, but without leaking any information. This
"anonymized" repository could then be shared with developers
(assuming it still replicates the original problem).

This patch implements an "--anonymize" option to
fast-export, which generates a stream that can recreate such
a repository. Producing a single stream makes it easy for
the caller to verify that they are not leaking any useful
information. You can get an overview of what will be shared
by running a command like:

  git fast-export --anonymize --all |
  perl -pe 's/\d+/X/g' |
  sort -u |
  less

which will show every unique line we generate, modulo any
numbers (each anonymized token is assigned a number, like
"User 0", and we replace it consistently in the output).

In addition to anonymizing, this produces test cases that
are relatively small (compared to the original repository)
and fast to generate (compared to using filter-branch, or
modifying the output of fast-export yourself). Here are
numbers for git.git:

  $ time git fast-export --anonymize --all \
         --tag-of-filtered-object=drop >output
  real    0m2.883s
  user    0m2.828s
  sys     0m0.052s

  $ gzip output
  $ ls -lh output.gz | awk '{print $5}'

26be19ba8d send-pack: take refspecs over stdin
Pushing a large number of refs works over most transports,
because we implement send-pack as an internal function.
However, it can sometimes fail when pushing over http,
because we have to spawn "git send-pack --stateless-rpc" to
do the heavy lifting, and we pass each refspec on the
command line. This can cause us to overflow the OS limits on
the size of the command line for a large push.

We can solve this by giving send-pack a --stdin option and
using it from remote-curl.  We already dealt with this on
the fetch-pack side in 078b895 (fetch-pack: new --stdin
option to read refs from stdin, 2012-04-02). The stdin
option (and in particular, its use of packet-lines for
stateless-rpc input) is modeled after that solution.

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

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.

afd11d3ebc pack-refs: prune top-level refs like "refs/foo"
After we have packed all refs, we prune any loose refs that
correspond to what we packed. We do so by first taking a
lock with lock_ref_sha1, and then deleting the loose ref
file.

However, lock_ref_sha1 will refuse to take a lock on any
refs that exist at the top-level of the "refs/" directory,
and we skip pruning the ref.  This is almost certainly not
what we want to happen here. The criteria to be pruned
should not differ from that to be packed; if a ref makes it
to prune_ref, it's because we want it both packed and
pruned (if there are refs you do not want to be packed, they
should be omitted much earlier by pack_ref_is_possible,
which we do in this case if --all is not given).

We can fix this by switching to lock_any_ref_for_update.
This behaves exactly the same with the exception of this
top-level check.

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.

c8466645ed make config --add behave correctly for empty and NULL values
Currently if we have a config file like,
[foo]
        baz
        bar =

and we try something like, "git config --add foo.baz roll", Git will
segfault. Moreover, for "git config --add foo.bar roll", it will
overwrite the original value instead of appending after the existing
empty value.

The problem lies with the regexp used for simulating --add in
`git_config_set_multivar_in_file()`, "^$", which in ideal case should
not match with any string but is true for empty strings. Instead use a
regexp like "a^" which can not be true for any string, empty or not.

For removing the segfault add a check for NULL values in `matches()` in
config.c.

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.

430875969a utf8.c: fix strbuf_utf8_replace() consuming data beyond input string
The main loop in strbuf_utf8_replace() could summed up as:

  while ('src' is still valid) {
    1) advance 'src' to copy ANSI escape sequences
    2) advance 'src' to copy/replace visible characters
  }

The problem is after #1, 'src' may have reached the end of the string
(so 'src' points to NUL) and #2 will continue to copy that NUL as if
it's a normal character. Because the output is stored in a strbuf,
this NUL accounted in the 'len' field as well. Check after #1 and
break the loop if necessary.

The test does not look obvious, but the combination of %>>() should
make a call trace like this

  show_log()
  pretty_print_commit()
  format_commit_message()
  strbuf_expand()
  format_commit_item()
  format_and_pad_commit()
  strbuf_utf8_replace()

where %C(auto)%d would insert a color reset escape sequence in the end
of the string given to strbuf_utf8_replace() and show_log() uses
fwrite() to send everything to stdout (including the incorrect NUL
inserted by strbuf_utf8_replace)

288c67caf6 stash: default listing to working-tree diff
When you list stashes, you can provide arbitrary git-log
options to change the display. However, adding just "-p"
does nothing, because each stash is actually a merge commit.

This implementation detail is easy to forget, leading to
confused users who think "-p" is not working. We can make
this easier by defaulting to "--first-parent -m", which will
show the diff against the working tree. This omits the
index portion of the stash entirely, but it's simple and it
matches what "git stash show" provides.

People who are more clueful about stash's true form can use
"--cc" to override the "-m", and the "--first-parent" will
then do nothing. For diffs, it only affects non-combined
diffs, so "--cc" overrides it. And for the traversal, we are
walking the linear reflog anyway, so we do not even care
about the parents.

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.

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.

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.

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.

1e0dacdbdb rebase: omit patch-identical commits with --fork-point
When the `--fork-point` argument was added to `git rebase`, we changed
the value of $upstream to be the fork point instead of the point from
which we want to rebase.  When $orig_head..$upstream is empty this does
not change the behaviour, but when there are new changes in the upstream
we are no longer checking if any of them are patch-identical with
changes in $upstream..$orig_head.

Fix this by introducing a new variable to hold the fork point and using
this to restrict the range as an extra (negative) revision argument so
that the set of desired revisions becomes (in fork-point mode):

	git rev-list --cherry-pick --right-only \
		$upstream...$orig_head ^$fork_point

This allows us to correctly handle the scenario where we have the
following topology:

	    C --- D --- E  <- dev
	   /
	  B  <- master@{1}
	 /
	o --- B' --- C* --- D*  <- master

where:
- B' is a fixed-up version of B that is not patch-identical with B;
- C* and D* are patch-identical to C and D respectively and conflict
  textually if applied in the wrong order;
- E depends textually on D.

The correct result of `git rebase master dev` is that B is identified as
the fork-point of dev and master, so that C, D, E are the commits that
need to be replayed onto master; but C and D are patch-identical with C*
and D* and so can be dropped, so that the end result is:

	o --- B' --- C* --- D* --- E  <- dev

If the fork-point is not identified, then picking B onto a branch
containing B' results in a conflict and if the patch-identical commits
are not correctly identified then picking C onto a branch containing D
(or equivalently D*) results in a conflict.

This change allows us to handle both of these cases, where previously we
either identified the fork-point (with `--fork-point`) but not the
patch-identical commits *or* (with `--no-fork-point`) identified the
patch-identical commits but not the fact that master had been rewritten.

f0e802ca20 t5539: update a flaky test
The test creates some unrelated commits in two separate repositories,
and then fetches from one to the other. Since the commit creation
happens in a subshell, the first commit in each ends up with the
same test_tick value. When fetch-pack looks at the two root commits
"unrelated1" and "new-too", the exact sequence of ACKs is different
depending on which one it pulls out of the queue first.

With the current code, it happens to be "unrelated1" (though this is not
at all guaranteed by the prio_queue data structure, it is deterministic
for this particular sequence of input). We see the ready-ACK, and the
test succeeds.

With the stable queue, we reliably get "new-too" out (since it is our
local tip, it is added to the queue before we even talk to the remote).
We never see a ready-ACK, and the test fails due to the grep on the
TRACE_PACKET output at the end (the fetch itself succeeds as expected).

I'm really not quite clear on what's supposed to be going on in the
test. I can make it pass with this change.

e6ce2be2d7 tests: do not pass iso8859-1 encoded parameter
git commit -m with some iso8859-1 encoded stuff is doomed to fail in MinGW,
because Windows don't let you pass encoded bytes to a process (CreateProcessW
always takes a UTF-16LE encoded string).

It is safe to pass the iso8859-1 message using a file or a pipe.

9c4d6c0297 cache-tree: Write updated cache-tree after commit
During the commit process, update the cache-tree. Write this updated
cache-tree so that it's ready for subsequent commands.

Add test code which demonstrates that git commit now writes the cache
tree.  Make all tests test the entire cache-tree, not just the root
level.

42639d2317 submodules: add the lib-submodule-update.sh test library
Add this test library to simplify covering all combinations of submodule
update scenarios without having to add those to a test of each work tree
manipulating command over and over again.

The functions test_submodule_switch() and test_submodule_forced_switch()
are intended to be called from a test script with a single argument. This
argument is either a work tree manipulating command (including any command
line options) or a function (when more than a single git command is needed
to switch work trees from the current HEAD to another commit). This
command (or function) is passed a target branch as argument. The two new
functions check that each submodule transition is handled as expected,
which currently means that submodule work trees are not affected until
"git submodule update" is called. The "forced" variant is for commands
using their '-f' or '--hard' option and expects them to overwrite local
modifications as a result. Each of these two functions contains 14
tests_expect_* calls.

Calling one of these test functions the first time creates a repository
named "submodule_update_repo". At first it contains two files, then a
single submodule is added in another commit followed by commits covering
all relevant submodule modifications. This repository is newly cloned into
the "submodule_update" for each test_expect_* to avoid interference
between different parts of the test functions (some to-be-tested commands
also manipulate refs along with the work tree, e.g. "git reset").

Follow-up commits will then call these two test functions for all work
tree manipulating commands (with a combination of all their options
relevant to what they do with the work tree) making sure they work as
expected. Later this test library will be extended to cover merges
resulting in conflicts too. Also it is intended to be easily extendable
for the recursive update functionality, where even more combinations of
submodule modifications have to be tested for.

This version documents two bugs in current Git with expected failures:

*) When a submodule is replaced with a tracked file of the same name the
   submodule work tree including any local modifications (and even the
   whole history if it uses a .git directory instead of a gitfile!) is
   silently removed.

*) Forced work tree updates happily manipulate files in the directory of a
   submodule that has just been removed in the superproject (but is of
   course still present in the work tree due to the way submodules are
   currently handled). This becomes dangerous when files in the submodule
   directory are overwritten by files from the new superproject commit, as
   any modifications to the submodule files will be lost) and is expected
   to also destroy history in the - admittedly unlikely case - the new
   commit adds a file named ".git" to the submodule directory.
