727c3718a5 whitespace: we cannot "catch all errors known to git" anymore
Traditionally, "*.txt whitespace" in .gitattributes file has been an
instruction to catch _all_ classes of whitespace errors known to git.

This has to change, however, in order to introduce "tab-in-indent" which
is inherently incompatible with "indent-with-non-tab".  As we do not want
to break configuration of existing users, add a mechanism to allow marking
selected rules to be excluded from "all rules known to git".

b337398266 diff: avoid useless filespec population
builtin_diff calls fill_mmfile fairly early, which in turn
calls diff_populate_filespec, which actually retrieves the
file's blob contents into a buffer. Long ago, this was
sensible as we would need to look at the blobs eventually.

These days, however, we may not ever want those blobs if we
end up using a textconv cache, and for large binary files
(exactly the sort for which you might have a textconv
cache), just retrieving the objects can be costly.

This patch just pushes the fill_mmfile call a bit later, so
we can avoid populating the filespec in some cases.  There
is one thing to note that looks like a bug but isn't. We
push the fill_mmfile down into the first branch of a
conditional. It seems like we would need it on the other
branch, too, but we don't; fill_textconv does it for us (in
fact, before this, we were just writing over the results of
the fill_mmfile on that branch).

Here's a timing sample on a commit with 45 changed jpgs and
avis. The result is fully textconv cached, but we still
wasted a lot of time just pulling the blobs from storage.
The total size of the blobs (source and dest) is about
180M.

  [before]
  $ time git show >/dev/null
  real    0m0.352s
  user    0m0.148s
  sys     0m0.200s

  [after]
  $ time git show >/dev/null
  real    0m0.009s
  user    0m0.004s
  sys     0m0.004s

And that's on a warm cache. On a cold cache, the "after"
case is not much worse, but the "before" case has to do an
extra 180M of I/O.

d9bae1a178 diff: cache textconv output
Running a textconv filter can take a long time. It's
particularly bad for a large file which needs to be spooled
to disk, but even for small files, the fork+exec overhead
can add up for something like "git log -p".

This patch uses the notes-cache mechanism to keep a fast
cache of textconv output. Caches are stored in
refs/notes/textconv/$x, where $x is the userdiff driver
defined in gitattributes.

Caching is enabled only if diff.$x.cachetextconv is true.

In my test repo, on a commit with 45 jpg and avi files
changed and a textconv to show their exif tags:

  [before]
  $ time git show >/dev/null
  real    0m13.724s
  user    0m12.057s
  sys     0m1.624s

  [after, first run]
  $ git config diff.mfo.cachetextconv true
  $ time git show >/dev/null
  real    0m14.252s
  user    0m12.197s
  sys     0m1.800s

  [after, subsequent runs]
  $ time git show >/dev/null
  real    0m0.352s
  user    0m0.148s
  sys     0m0.200s

So for a slight (3.8%) cost on the first run, we achieve an
almost 40x speed up on subsequent runs.

840383b2c2 textconv: refactor calls to run_textconv
This patch adds a fill_textconv wrapper, which centralizes
some minor logic like error checking and handling the case
of no-textconv.

In addition to dropping the number of lines, this will make
it easier in future patches to handle multiple types of
textconv.

a941d5e395 introduce notes-cache interface
Notes provide a fast lookup mechanism for data keyed by
sha1. This is ideal for caching certain operations, like
textconv filters.

This patch builds some infrastructure to make it simpler to
use notes trees as caches. In particular, caches:

  1. don't have arbitrary commit messages. They store a
     cache validity string in the commit, and clear the tree
     when the cache validity string changes.

  2. don't keep any commit history. The accumulated history
     of a a cache is just useless cruft.

  3. use a looser form of locking for ref updates. If two
     processes try to write to the cache simultaneously, it
     is OK if one overwrites the other, losing some changes.
     It's just a cache, so we will just end up with an extra
     miss.

40d52ff77b make commit_tree a library function
Until now, this has been part of the commit-tree builtin.
However, it is already used by other builtins (like commit,
merge, and notes), and it would be useful to access it from
library code.

The check_valid helper has to come along, too, but is given
a more library-ish name of "assert_sha1_type".

Otherwise, the code is unchanged. There are still a few
rough edges for a library function, like printing the utf8
warning to stderr, but we can address those if and when they
come up as inappropriate.

These should take const buffers as input data, but zlib's
next_in pointer is not const-correct. Let's fix it at the

a50dec22f2 Makefile: update defaults for modern Cygwin
Now that Cygwin 1.7.x has enabled lots of new features, and Cygwin 1.5
is no longer actively supported by the Cygwin mailing lists, we might
as well update the defaults to cater to those new features.

NO_TRUSTABLE_FILEMODE is only necessary on FAT drives; the Cygwin
community recommends NTFS drives, but there is still too much use
for FAT to switch the default.  Likewise, UNRELIABLE_FSTAT is probably
file-system specific, but worth keeping unchanged.

This commit does not change the default for NO_MMAP, although definitive
proof of whether this option is necessary is lacking.

42653c09c8 Prompt for a username when an HTTP request 401s
When an HTTP request returns a 401, Git will currently fail with a
confusing message saying that it got a 401, which is not very
descriptive.

Currently if a user wants to use Git over HTTP, they have to use one
URL with the username in the URL (e.g. "http://user@host.com/repo.git")
for write access and another without the username for unauthenticated
read access (unless they want to be prompted for the password each
time). However, since the HTTP servers will return a 401 if an action
requires authentication, we can prompt for username and password if we
see this, allowing us to use a single URL for both purposes.

This patch changes http_request to prompt for the username and password,
then return HTTP_REAUTH so http_get_strbuf can try again.  If it gets
a 401 even when a user/pass is supplied, http_request will now return
HTTP_NOAUTH which remote_curl can then use to display a more
intelligent error message that is less confusing.

21e403a7b9 Don't redefine htonl and ntohl on big-endian
Since commit 0fcabdeb52, compat/bswap.h
redefined htonl and ntohl to bswap32 not only if bswap32 has been
defined earlier in compat/bswap.h (which is done only on selected
platforms), but also if bswap32 has been defined anywhere else.  This
broke Git at least for NetBSD systems running on big-endian machines
(where ntohl and htonl should, of course, be NOOPs), since NetBSD
defines a bswap32 macro in the system headers.

So, we now undefine any previously defined bswap32 in compat/bswap.h
before defining our own.

"has_key" is a deprecated dictionary method in Python 2.6+.
Simplify the sys.path manipulation for installed scripts by
passing a default value to os.getenv() that takes a default

SCRIPT_PYTHON is currently empty but this future-proofs us.
It also fixes things for users who maintain local git forks
with their own SCRIPT_PYTHON additions.

Old code replaced the first element of sys.path[] which is
typically '' (i.e. import library files relative to the script).
It is safer to prepend the extra library path instead.

[The test is designed to exercise both arms of the 'if' in question.]

Furthermore, recording the stopped-sha (the SHA1 of the commit before
the editing) suffered from a cut&paste error from die_with_patch and
used the wrong variable, hence it never recorded anything.

This patch moves the warning code of the unlink_or_warn function into
a separate function named warn_if_unremovable so that it may be reused.

42accaec01 difftool: Fix '--gui' when diff.guitool is unconfigured
When diff.guitool is unconfigured and "--gui" is specified
git-difftool dies with the following error message:

	config diff.guitool: command returned error: 1

Catch the error so that the "--gui" flag is a no-op when
diff.guitool is unconfigured.

bb6ad28c23 fast-export: don't segfault when marks file cannot be opened
The error function only prints an error message, resulting in a
segfault if we later on try to fprintf to a NULL handle.

Fix this by using die_errno instead.
