Merge branch 'dt/name-hash-dir-entry-fix' into maint
The name-hash subsystem that is used to cope with case insensitive
filesystems keeps track of directories and their on-filesystem
cases for all the paths in the index by holding a pointer to a
randomly chosen cache entry that is inside the directory (for its
ce->ce_name component). This pointer was not updated even when the
cache entry was removed from the index, leading to use after free.
This was fixed by recording the path for each directory instead of
borrowing cache entries and restructuring the API somewhat.

Git-merge-file is documented to return one of three exit
codes:
- zero means the merge was successful
- a negative number means an error occurred
- a positive number indicates the number of conflicts
Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).
This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).
Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform. We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the

This breaks the recently added sanity checks for the insn sheet fed

not do any adjustment--hence the double-dashes will be seen in the

Stop reusing cache_entry in dir_entry; doing so causes a
use-after-free bug.
During merges, we free entries that we no longer need in the
destination index. But those entries might have also been stored in
the dir_entry cache, and when a later call to add_to_index found them,
they would be used after being freed.
To prevent this, change dir_entry to store a copy of the name instead
of a pointer to a cache_entry. This entails some refactoring of code
that expects the cache_entry.

usage: do not insist that standard input must come from a file
The synopsys text and the usage string of subcommands that read list
of things from the standard input are often shown like this:
git gostak [--distim] < <list-of-doshes>
This is problematic in a number of ways:
* The way to use these commands is more often to feed them the
output from another command, not feed them from a file.
* Manual pages outside Git, commands that operate on the data read
from the standard input, e.g "sort", "grep", "sed", etc., are not
described with such a "< redirection-from-file" in their synopsys
text. Our doing so introduces inconsistency.
* We do not insist on where the output should go, by saying
* As it is our convention to enclose placeholders inside <braket>,
the redirection operator followed by a placeholder filename
becomes very hard to read, both in the documentation and in the

Let's clean them all up, after making sure that the documentation
clearly describes the modes that take information from the standard
input and what kind of things are expected on the input.

filter-branch: remove multi-line headers in msg filter
df062010 (filter-branch: avoid passing commit message through sed)
introduced a regression when filtering commits with multi-line headers,
if the header contains a blank line. An example of this is a gpg-signed
commit:
As a consequence, "filter-branch --msg-filter cat" (which should leave the
commit message unchanged) spills the signature (after the internal blank
line) into the original commit message.
The reason is that although the signature is indented, making the line a
whitespace only line, the "read" call is splitting the line based on
the shell's IFS, which defaults to <space><tab><newline>. The leading
space is consumed and $header_line is empty, causing the "skip header
lines" loop to exit.
The rest of the commit object is then re-used as the rewritten commit
message, causing the new message to include the signature of the
original commit.
Set IFS to an empty string for the "read" call, thus disabling the word
splitting, which causes $header_line to be set to the non-empty value ' '.
This allows the loop to fully consume the header lines before
emitting the original, intact commit message.

am -3: do not let failed merge from completing the error codepath
When "am" was rewritten in C, the codepath for falling back to
three-way merge was mistakenly made to make an internal call to
merge-recursive, disabling the error reporting code for certain
types of errors merge-recursive detects and reports by calling
die().
This is a quick-fix for correctness. The ideal endgame would be to
replace run_command() in run_fallback_merge_recursive() with a
direct call after making sure that internal call to merge-recursive
does not die().
In normalize_ceiling_entry(), we test that normalized paths end with
slash, *unless* the path to be normalized was already the root
directory.
However, normalize_path_copy() does not even enforce this condition.
Even worse: on Windows, the root directory gets translated into a
Windows directory by the Bash before being passed to `git.exe` (or
`test-path-utils.exe`), which means that we cannot even know whether
the path that was passed to us was the root directory to begin with.
This issue has already caused endless hours of trying to "fix" the
MSYS2 runtime, only to break other things due to MSYS2 ensuring that
the converted path maintains the same state as the input path with
respect to any final '/'.
So let's just forget about this test. It is non-essential to Git's
operation, anyway.

the pack files need to be repacked. In that case, the pack files need to

pack files.
On platforms where a file cannot be deleted if another process still
holds a handle on it, we therefore need to take pains to release all
pack files and indexes before dissociating.

804098bb (git rebase -i: add static check for commands and SHA-1,
2015-06-29) tried to check all insns before running any in the todo

stricter than necessary. We used to allow lines that are indented
(including comment lines), and we used to allow a whitespace between
the insn and the commit object name to be HT, among other things,
that are flagged as an invalid line by mistake.
Fix this by using the same tokenizer that is used to parse the todo
list file in the new check.
Whether it's a good thing to accept indented comments is
debatable (other commands like "git commit" do not accept them), but we
already accepted them in the past, and some people and scripts rely on
this behavior. Also, a line starting with space followed by a '#' cannot
have any meaning other than being a comment, hence it doesn't harm to
accept them as comments.

rebase-i: explicitly accept tab as separator in commands
The git-rebase-todo is parsed several times with different parsers. In
principle, the user input is normalized by transform_todo_ids and
further parsing can be stricter.
the parser of transform_todo_ids was considering the sha1 to be
"deadbeef<TAB>commit", and was leaving the tab in the transformed sheet.
In practice, this went unnoticed since the actual command interpretation
was done later in do_next which did accept the tab as a separator.
Make it explicit in the code of transform_todo_ids that tabs are
accepted. This way, code that mimicks it will also accept tabs as
separator.
A similar construct appears in skip_unnecessary_picks, but this one
comes after transform_todo_ids, hence reads the normalized format, so it
needs not be changed.

merge-file: enforce MAX_XDIFF_SIZE on incoming files
The previous commit enforces MAX_XDIFF_SIZE at the
interfaces to xdiff: xdi_diff (which calls xdl_diff) and
ll_xdl_merge (which calls xdl_merge).
But we have another direct call to xdl_merge in
merge-file.c. If it were written today, this probably would
just use the ll_merge machinery. But it predates that code,
and uses slightly different options to xdl_merge (e.g.,
ZEALOUS_ALNUM).
We could try to abstract out an xdi_merge to match the
existing xdi_diff, but even that is difficult. Rather than
simply report error, we try to treat large files as binary,
and that distinction would happen outside of xdi_merge.
The simplest fix is to just replicate the MAX_XDIFF_SIZE
check in merge-file.c.

The xdiff code is not prepared to handle extremely large
files. It uses "int" in many places, which can overflow if
we have a very large number of lines or even bytes in our
input files. This can cause us to produce incorrect diffs,
with no indication that the output is wrong. Or worse, we
may even underallocate a buffer whose size is the result of
an overflowing addition.
We're much better off to tell the user that we cannot diff
or merge such a large file. This patch covers both cases,
but in slightly different ways:
1. For merging, we notice the large file and cleanly fall
back to a binary merge (which is effectively "we cannot
merge this").
2. For diffing, we make the binary/text distinction much
earlier, and in many different places. For this case,
we'll use the xdi_diff as our choke point, and reject
any diff there before it hits the xdiff code.
This means in most cases we'll die() immediately after.
That's not ideal, but in practice we shouldn't
generally hit this code path unless the user is trying
to do something tricky. We already consider files
larger than core.bigfilethreshold to be binary, so this
code would only kick in when that is circumvented
(either by bumping that value, or by using a
.gitattribute to mark a file as diffable).
In other words, we can avoid being "nice" here, because
there is already nice code that tries to do the right
thing. We are adding the suspenders to the nice code's
belt, so notice when it has been worked around (both to
protect the user from malicious inputs, and because it
is better to die() than generate bogus output).
The maximum size was chosen after experimenting with feeding
large files to the xdiff code. It's just under a gigabyte,
which leaves room for two obvious cases:
- a diff3 merge conflict result on files of maximum size X
could be 3*X plus the size of the markers, which would
still be only about 3G, which fits in a 32-bit int.
- some of the diff code allocates arrays of one int per
record. Even if each file consists only of blank lines,
then a file smaller than 1G will have fewer than 1G
records, and therefore the int array will fit in 4G.
Since the limit is arbitrary anyway, I chose to go under a
gigabyte, to leave a safety margin (e.g., we would not want
to overflow by allocating "(records + 1) * sizeof(int)" or
similar.
