df747b81 (convert.c: refactor crlf_action, 2016-02-10) introduced a
bug to "git ls-files --eol".
The "text" attribute was shown as "text eol=lf" or "text eol=crlf",
depending on core.autocrlf or core.eol.
Correct this and add test cases in t0027.

Simplify the statistics:
lonecr counts the CR which is not followed by a LF,
lonelf counts the LF which is not preceded by a CR,
crlf counts CRLF combinations.
This simplifies the evaluation of the statistics.

Refactor the determination and usage of crlf_action.
Today, when no "crlf" attribute are set on a file, crlf_action is set to
CRLF_GUESS. Use CRLF_UNDEFINED instead, and search for "text" or "eol" as
before.
After searching for line ending attributes, save the value in
struct conv_attrs.crlf_action attr_action,
so that get_convert_attr_ascii() is able report the attributes.
Replace the old CRLF_GUESS usage:
CRLF_GUESS && core.autocrlf=true -> CRLF_AUTO_CRLF
CRLF_GUESS && core.autocrlf=false -> CRLF_BINARY
CRLF_GUESS && core.autocrlf=input -> CRLF_AUTO_INPUT
Save the action in conv_attrs.crlf_action (as before) and change
all callers.
Make more clear, what is what, by defining:
- CRLF_UNDEFINED : No attributes set. Temparally used, until core.autocrlf
and core.eol is evaluated and one of CRLF_BINARY,
CRLF_AUTO_INPUT or CRLF_AUTO_CRLF is selected
- CRLF_BINARY : No processing of line endings.
- CRLF_TEXT : attribute "text" is set, line endings are processed.
- CRLF_TEXT_INPUT: attribute "input" or "eol=lf" is set. This implies text.
- CRLF_TEXT_CRLF : attribute "eol=crlf" is set. This implies text.
- CRLF_AUTO : attribute "auto" is set.
- CRLF_AUTO_INPUT: core.autocrlf=input (no attributes)
- CRLF_AUTO_CRLF : core.autocrlf=true (no attributes)

When a filter is configured, a different code-path is used in convert.c
and entry.c via get_stream_filter(), but there are no test cases yet.
Add tests for the filter API by configuring the ident filter.
The result of the SHA1 conversion is not checked, this is already
done in other TC.
Add a parameter to checkout_files() in t0027.
While changing the signature, add another parameter for the eol= attribute.
This is currently unused, tests for e.g.
"* text=auto eol=lf" will be added in a separate commit.

When working in a cross-platform environment, a user may want to
check if text files are stored normalized in the repository and
if .gitattributes are set appropriately.
Make it possible to let Git show the line endings in the index and
in the working tree and the effective text/eol attributes.
The end of line ("eolinfo") are shown like this:
"-text" binary (or with bare CR) file
"none" text file without any EOL
"lf" text file with LF
"crlf" text file with CRLF
"mixed" text file with mixed line endings.
The effective text/eol attribute is one of these:
"", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf"
git ls-files --eol gives an output like this:
i/none w/none attr/text=auto t/t5100/empty
i/-text w/-text attr/-text t/test-binary-2.png
i/lf w/lf attr/text eol=lf t/t5100/rfc2047-info-0007
i/lf w/crlf attr/text eol=crlf doit.bat
i/mixed w/mixed attr/ locale/XX.po
to show what eol convention is used in the data in the index ('i'),
and in the working tree ('w'), and what attribute is in effect,
for each path that is shown.
Add test cases in t0027.

"git notes merge" used to limit the source of the merged notes tree
to somewhere under refs/notes/ hierarchy, which was too limiting
when inventing a workflow to exchange notes with remote
repositories using remote-tracking notes trees (located in e.g.
refs/remote-notes/ or somesuch).

Create a new expansion function, expand_loose_notes_ref which will first
check whether the ref can be found using get_sha1. If it can't be found
then it will fallback to using expand_notes_ref. The content of the
strbuf will not be changed if the notes ref can be located using
get_sha1. Otherwise, it may be updated as done by expand_notes_ref.
Since we now support merging from non-notes refs, remove the test case
associated with that behavior. Add a test case for merging from a
non-notes ref.

Many commands that read files that are expected to contain text
that is generated (or can be edited) by the end user to control
their behaviour (e.g. "git grep -f <filename>") have been updated
to be more tolerant to lines that are terminated with CRLF (they
used to treat such a line to contain payload that ends with CR,
which is usually not what the users expect).

List of patterns file could come from a DOS editor.
This is iffy; you may actually be trying to find a line with ^M in
it on a system whose line ending is LF. You can of course work it
around by having a line that has "^M^M^J", let the strbuf_getline()
eat the last "^M^J", leaving just the single "^M" as the pattern.

Our implementation of helpers never use CRLF line endings, and they
do not depend on the ability to place a CR as payload at the end of
the line, so this is essentially a no-op for in-tree users. However,
this allows third-party implementation of helpers to give us their
line with CRLF line ending (they cannot expect us to feed CRLF to
them, though).

Reading with getwholeline() and manually stripping the terminating
'\n' would leave CR at the end of the line if the input comes from
a DOS editor.
Constrasting this with the other changes around "--stdin" in this
series, one may realize that the way "log" family of commands read
the paths with "--stdin" looks inconsistent and sloppy. It does not
allow us to C-quote a textual input, neither does it accept records
that are NUL-terminated. These are unfortunately way too late to
fix X-<.

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.

Because this script has to test so many formatters, we have
the nice "test_atom" helper, but we don't use it
consistently. Let's do so. This is shorter, gets rid of some
tests that have their "expected" setup outside of a
test_expect_success block, and lets us organize the changes
better (e.g., putting "refname:short" near "refname").
We also expand the "%(push)" tests a little to match the
"%(upstream)" ones.

For users with "store-passwords = no" set in the "[auth]" section of
their ~/.subversion/config, SVN 1.9.0+ would fail with the
following message when attempting to call svn_auth_set_parameter:
Value is not a string (or undef) at Git/SVN/Ra.pm
Ironically, this breakage was caused by r1553823 in subversion:
"Make svn_auth_set_parameter() usable from Perl bindings."
Since 2007 (602015e0e6ec), git-svn has used a workaround to make
svn_auth_set_parameter usable internally. However this workaround
breaks under SVN 1.9+, which deals properly with the type mapping
and fails to recognize our workaround.
For pre-1.9.0 SVN, we continue to use the existing workaround for
the lack of proper type mapping in the bindings.
Tested under subversion 1.6.17 and 1.9.3.
I've also verified r1553823 was not backported to SVN 1.8.x:

Git tries to avoid creating a commit with an empty author
name or email. However, commits created by older, less
strict versions of git may still be in the history. There's
not much point in issuing a warning to stderr for an empty
author. The user can't do anything about it now, and we are
better off to simply include it in the shortlog output as an
empty name/email, and let the caller process it however they
see fit.
Older versions of shortlog differentiated between "author
header not present" (which complained) and "author
name/email are blank" (which included the empty ident in the
output). But since switching to format_commit_message, we
complain to stderr about either case (linux.git has a blank
author deep in its history which triggers this).
We could try to restore the older behavior (complaining only
about the missing header), but in retrospect, there's not
much point in differentiating these cases. A missing
author header is bogus, but as for the "blank" case, the
only useful behavior is to add it to the "empty name"
collection.

If we are in "--summary" mode, then we do not care about the
actual list of subject onelines associated with each author.
We care only about the number. So rather than store a
string-list for each author full of "<none>", let's just
keep a count.
This drops my best-of-five for "git shortlog -ns HEAD" on
linux.git from:
real 0m5.194s
user 0m5.028s
sys 0m0.168s
to:
real 0m5.057s
user 0m4.916s
sys 0m0.144s
That's about 2.5%.

If we are in --summary mode, we will always pass <none> to
insert_one_record, which will then do some normalization
(e.g., cutting out "[PATCH]"). There's no point in doing so
if we aren't going to use the result anyway.
This drops my best-of-five for "git shortlog -ns HEAD" on
linux.git from:
real 0m5.257s
user 0m5.104s
sys 0m0.156s
to:
real 0m5.194s
user 0m5.028s
sys 0m0.168s
That's only 1%, but arguably the result is clearer to read,
as we're able to group our variable declarations inside the
conditional block. It also opens up further optimization
possibilities for future patches.

If the user asked us only to show counts for each author,
rather than the individual summary lines, then there is no
point in us generating the summaries only to throw them
away. With this patch, I measured the following speedup for
"git shortlog -ns HEAD" on linux.git (best-of-five):
[before]
real 0m5.644s
user 0m5.472s
sys 0m0.176s
[after]
real 0m5.257s
user 0m5.104s
sys 0m0.156s
That's only ~7%, but it's so easy to do, there's no good
reason not to. We don't have to touch any downstream code,
since we already fill in the magic string "<none>" to handle
commits without a message.

When gathering the author and oneline subject for each
commit, we hand-parse the commit headers to find the
"author" line, and then continue past to the blank line at
the end of the header.
We can replace this tricky hand-parsing by simply asking the
pretty-printer for the relevant items. This also decouples
the author and oneline parsing, opening up some new
optimizations in further commits.
One reason to avoid the pretty-printer is that it might be
less efficient than hand-parsing. However, I measured no
slowdown at all running "git shortlog -ns HEAD" on
linux.git.
As a bonus, we also fix a memory leak in the (uncommon) case
that the author field is blank.

We currently use fixed-size buffers with fgets(), which
could lead to incorrect results in the unlikely event that a
line had something like "Author:" at exactly its 1024th
character.
But it's easy to convert this to a strbuf, and because we
can reuse the same buffer through the loop, we don't even
pay the extra allocation cost.

The original git-shortlog could read both the normal "git
log" output as well as "git log --format=raw". However, when
it was converted to C by b8ec592 (Build in shortlog,
2006-10-22), the trailing colon became mandatory, and we no
longer matched the raw output.
Given the amount of intervening time without any bug
reports, it's probable that nobody cares. But it's
relatively easy to fix, and the end result is hopefully more
readable than the original.
Note that this no longer matches "author: ", which we did
before, but that has never been a format generated by git.

The preliminary clean-up for jc/peace-with-crlf topic.
* jc/strbuf-getline:
strbuf: give strbuf_getline() to the "most text friendly" variant
checkout-index: there are only two possible line terminations
update-index: there are only two possible line terminations
check-ignore: there are only two possible line terminations
check-attr: there are only two possible line terminations
mktree: there are only two possible line terminations
strbuf: introduce strbuf_getline_{lf,nul}()
strbuf: make strbuf_getline_crlf() global
strbuf: miniscule style fix

Now there is no direct caller to strbuf_getline(), we can demote it
to file-scope static that is private to strbuf.c and rename it to
strbuf_getdelim(). Rename strbuf_getline_crlf(), which is designed
to be the most "text friendly" variant, and allow it to take over
this simplest name, strbuf_getline(), so we can add more uses of it
without having to type _crlf over and over again in the coming
steps.

The program by default reads LF terminated lines, with an option to
use NUL terminated records. Instead of pretending that there can be
other useful values for line_termination, use a boolean variable,
nul_term_line, to tell if NUL terminated records are used, and
switch between strbuf_getline_{lf,nul} based on it.

The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago. No useful caller that uses other value has emerged.
By now, it is clear that the interface is overly broad without a
good reason. Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.
This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them. The changes contained in this patch are:
* introduction of these two functions in strbuf.[ch]
* mechanical conversion of all callers to strbuf_getline() with
either '\n' or '\0' as the third parameter to instead call the
respective thin wrapper.
After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller. An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

Often we read "text" files that are supplied by the end user
(e.g. commit log message that was edited with $GIT_EDITOR upon 'git
commit -e'), and in some environments lines in a text file are
terminated with CRLF. Existing strbuf_getline() knows to read a
single line and then strip the terminating byte from the result, but
it is handy to have a version that is more tailored for a "text"
input that takes both '\n' and '\r\n' as line terminator (aka
<newline> in POSIX lingo) and returns the body of the line after
stripping <newline>.
Recently reimplemented "git am" uses such a function implemented
privately; move it to strbuf.[ch] and make it available for others.
Note that we do not blindly replace calls to strbuf_getline() that
uses LF as the line terminator with calls to strbuf_getline_crlf()
and this is very much deliberate. Some callers may want to treat an
incoming line that ends with CR (and terminated with LF) to have a
payload that includes the final CR, and such a blind replacement
will result in misconversion when done without code audit.
