"git log --show-signature" and other commands that display the
verification status of PGP signature now shows the longer key-id,
as 32-bit key-id is so last century.

Linus's original was rebased to apply to the maintenance track just
in case binary distributors that are stuck in the past want to take
it to their older codebase. Let's merge it up to more modern
codebase that has Peff's gpg-interface clean-up topic that appeared
after Git 2.9 was tagged.

Yes, gpg2 already uses the long format by default, but most
distributions seem to still have "gpg" be the older 1.x version due to
compatibility reasons. And older versions of gpg only show the 32-bit
short ID, which is quite insecure.
This doesn't actually matter for the _verification_ itself: if the
verification passes, the pgp signature is good. But if you don't
actually have the key yet, and want to fetch it, or you want to check
exactly which key was used for verification and want to check it, we
should specify the key with more precision.
In fact, we should preferentially specify the whole key fingerprint, but
gpg doesn't actually support that. Which is really quite sad.
Showing the "long" format improves things to at least show 64 bits of
the fingerprint. That's a lot better, even if it's not perfect.
This change the log format for "git log --show-signature" from

(note the longer key ID, but also the reflowing of the text) and also
changes the format in the merge messages when merging a signed
tag.
If you already use gpg2 (either because it's installed by default, or
because you have set your gpg_program configuration to point to gpg2),
that already used the long format, you'll also see a change: it will now
have the same formatting as gpg 1.x, and the verification string looks
something like

so there is certainly a chance this could break some automated scripting.
But the 32-bit key ID's really are broken. Also note that because of the
differences between gpg-1.x and gpg-2.x, hopefully any scripted key ID
parsing code (if such code exists) is already flexible enough to not care.
This was triggered by the fact that the "evil32" project keys ended up
leaking to the public key servers, so now there are 32-bit aliases for
just about every open source developer that you can easily get by
mistake if you use the 32-bit short ID format.

"git rev-parse --git-path hooks/<hook>" learned to take
core.hooksPath configuration variable (introduced during 2.9 cycle)
into account.

The idea of the --git-path option is not only to avoid having to
prefix paths with the output of --git-dir all the time, but also to
respect overrides for specific common paths inside the .git directory
(e.g. `git rev-parse --git-path objects` will report the value of the
environment variable GIT_OBJECT_DIRECTORY, if set).
When introducing the core.hooksPath setting, we forgot to adjust
git_path() accordingly. This patch fixes that.
While at it, revert the special-casing of core.hooksPath in
run-command.c, as it is now no longer needed.

"git difftool" by default ignores the error exit from the backend
commands it spawns, because often they signal that they found
differences by exiting with a non-zero status code just like "diff"
does; the exit status codes 126 and above however are special in
that they are used to signal that the command is not executable,
does not exist, or killed by a signal. "git difftool" has been
taught to notice these exit status codes.

"git checkout --detach <branch>" used to give the same advice
message as that is issued when "git checkout <tag>" (or anything

When a non-reversible CRLF conversion is done in "git add",
a warning is printed on stderr (or Git dies, depending on checksafe)
The function commit_chk_wrnNNO() in t0027 was written to test this,
but did the wrong thing: Instead of looking at the warning
from "git add", it looked at the warning from "git commit".
This is racy because "git commit" may not have to do CRLF conversion
at all if it can use the sha1 value from the index (which depends on
whether "add" and "commit" run in a single second).
Correct t0027 and replace the commit for each and every file with a commit
of all files in one go.
The function commit_chk_wrnNNO() should be renamed in a separate commit.
Now that t0027 does the right thing, it detects a bug in covert.c:
This sequence should generate the warning `LF will be replaced by CRLF`,
but does not:
$ git init
$ git config core.autocrlf false
$ printf "Line\r\n" >file
$ git add file
$ git commit -m "commit with CRLF"
$ git config core.autocrlf true
$ printf "Line\n" >file
$ git add file
"git add" calls crlf_to_git() in convert.c, which calls check_safe_crlf().
When has_cr_in_index(path) is true, crlf_to_git() returns too early and
check_safe_crlf() is not called at all.
Factor out the code which determines if "git checkout" converts LF->CRLF
into will_convert_lf_to_crlf().
Update the logic around check_safe_crlf() and "simulate" the possible
LF->CRLF conversion at "git checkout" with help of will_convert_lf_to_crlf().
Thanks to Jeff King <peff@peff.net> for analyzing t0027.

When "git rebase" tries to compare set of changes on the updated
upstream and our own branch, it computes patch-id for all of these
changes and attempts to find matches. This has been optimized by
lazily computing the full patch-id (which is expensive) to be
compared only for changes that touch the same set of paths.
* kw/patch-ids-optim:
rebase: avoid computing unnecessary patch IDs
patch-ids: add flag to create the diff patch id using header only data
patch-ids: replace the seen indicator with a commit pointer
patch-ids: stop using a hand-rolled hashmap implementation

The `rebase` family of Git commands avoid applying patches that were
already integrated upstream. They do that by using the revision walking
option that computes the patch IDs of the two sides of the rebase
(local-only patches vs upstream-only ones) and skipping those local
patches whose patch ID matches one of the upstream ones.
In many cases, this causes unnecessary churn, as already the set of
paths touched by a given commit would suffice to determine that an
upstream patch has no local equivalent.
This hurts performance in particular when there are a lot of upstream
patches, and/or large ones.
Therefore, let's introduce the concept of a "diff-header-only" patch ID,
compare those first, and only evaluate the "full" patch ID lazily.
Please note that in contrast to the "full" patch IDs, those
"diff-header-only" patch IDs are prone to collide with one another, as
adjacent commits frequently touch the very same files. Hence we now
have to be careful to allow multiple hash entries with the same hash.
We accomplish that by using the hashmap_add() function that does not even
test for hash collisions. This also allows us to evaluate the full patch ID
lazily, i.e. only when we found commits with matching diff-header-only
patch IDs.
We add a performance test that demonstrates ~1-6% improvement. In
practice this will depend on various factors such as how many upstream
changes and how big those changes are along with whether file system
caches are cold or warm. As Git's test suite has no way of catching
performance regressions, we also add a regression test that verifies
that the full patch ID computation is skipped when the diff-header-only
computation suffices.

This will allow a diff patch id to be created using only the header data
so that the contents of the file will not have to be loaded.

The cherry_pick_list was looping through the original side checking the
seen indicator and setting the cherry_flag on the commit. If we save
off the commit in the patch_id we can set the cherry_flag on the correct
commit when running through the other side when a patch_id match is found.

This change will use the hashmap from the hashmap.h to keep track of the
patch_ids that have been encountered instead of using an internal
implementation. This simplifies the implementation of the patch ids.

The http-backend (the server-side component of smart-http
transport) used to trickle the HTTP header one at a time. Now
these write(2)s are batched.

Avoid waking up the readers for unnecessary context switches for
each line of header data being written, as all the headers are
written in short succession.
It is unlikely any HTTP/1.x server would want to read a CGI
response one-line-at-a-time and trickle each to the client.
Instead, I'd expect HTTP servers want to minimize syscall and
TCP/IP framing overhead by trying to send all of its response
headers in a single syscall or even combining the headers and
first chunk of the body with MSG_MORE or writev.
Verified by strace-ing response parsing on the CGI side.

write_global_extended_header() earlier.

If the trace code cannot open a specified file, or does not
understand the contents of the GIT_TRACE variable, it falls
back to printing trace output to stderr.
This is an attempt to be helpful, but in practice it just
ends up annoying. The user was trying to get the output to
go somewhere else, so spewing it to stderr does not really
accomplish that. And as it's intended for debugging, they
can presumably re-run the command with their error
corrected.
So instead of falling back, this patch disables bogus trace
keys for the rest of the program, just as we do for write
errors. We can drop the "Defaulting to..." part of the error
message entirely; after seeing "cannot open '/foo'", the
user can assume that tracing is skipped.

This function has no callers, and is not likely to gain any
because it's confusing to use.
It unconditionally complains to stderr, but _doesn't_ die.
Yet any caller which wants a "gentle" write would generally
want to suppress the error message, because presumably
they're going to write a better one, and/or try the
operation again.
And the check_pipe() call leads to confusing behaviors. It
means we die for EPIPE, but not for other errors, which is
confusing and pointless.
On top of all that, it has unusual error return semantics,
which makes it easy for callers to get it wrong.
Let's drop the function, and if somebody ever needs to
resurrect something like it, they can fix these warts.

If we get a write error writing to a trace descriptor, the
error isn't likely to go away if we keep writing. Instead,
you'll just get the same error over and over. E.g., try:
GIT_TRACE_PACKET=42 git ls-remote >/dev/null
You don't really need to see:
warning: unable to write trace for GIT_TRACE_PACKET: Bad file descriptor
hundreds of times. We could fallback to tracing to stderr,
as we do in the error code-path for open(), but there's not
much point. If the user fed us a bogus descriptor, they're
probably better off fixing their invocation. And if they
didn't, and we saw a transient error (e.g., ENOSPC writing
to a file), it probably doesn't help anybody to have half of
the trace in a file, and half on stderr.

Our error message for write() always mentions GIT_TRACE,
even though we may be writing for a different variable
entirely. It's also not quite accurate to say "fd given by
GIT_TRACE environment variable", as we may hit this error
based on a filename the user put in the variable (we do
complain and switch to stderr if the file cannot be opened,
but it's still possible to hit a write() error on the
descriptor later).
So let's fix those things, and switch to our more usual
"unable to do X: Y" format for the error.

The error messages for the trace code are often multi-line;
the first line gets a nice "warning:", but the rest are
left-aligned. Let's give them an indentation to make sure
they stand out as a unit.
While we're here, let's also downcase the first letter of
each error (our usual style), and break up a long line of
advice (since we're already using multiple lines, one more
doesn't hurt).
We also replace "What does 'foo' for GIT_TRACE mean?". While
cute, it's probably a good idea to give more context, and
follow our usual styles. So it's now "unknown trace value
for 'GIT_TRACE': foo".

Right now we just fprintf() straight to stderr, which can
make the output hard to distinguish. It would be helpful to
give it one of our usual prefixes like "error:", "warning:",
etc.
It doesn't make sense to use error() here, as the trace code
is "optional" debugging code. If something goes wrong, we
should warn the user, but saying "error" implies the actual
git operation had a problem. So warning() is the only sane
choice.
Note that this does end up calling warn_routine() to do the
formatting. This is probably a good thing, since they are
clearly trying to hook messages before they make it to
stderr. However, it also means that in theory somebody who
tries to trace from their warn_routine() could cause a loop.
This seems rather unlikely in practice (we've never even
overridden the default warn_builtin routine before, and
recent discussions to do so would just install a noop
routine).

The write_or_whine_pipe function does two things:
1. it checks for EPIPE and converts it into a signal death
2. it prints a message to stderr on error
The first thing does not help us, and actively hurts.
Generally we would simply die from SIGPIPE in this case,
unless somebody has taken the time to ignore SIGPIPE for the
whole process. And if they _did_ do that, it seems rather
silly for the trace code, which otherwise takes pains to
continue even in the face of errors (e.g., by not using
write_or_die!), to take down the whole process for one
specific type of error.
Nor does the second thing help us; it just makes it harder
to write our error message, because we have to feed bits of
it as an argument to write_or_whine_pipe(). Translators
never get to see the full message, and it's hard for us to
customize it.
Let's switch to just using write_in_full() and writing our
own error string. For now, the error is identical to what
write_or_whine_pipe() would say, but now that it's more
under our control, we can improve it in future patches.
