diff_grep: use textconv buffers for add/deleted files
If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.
However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.
Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.

It has been observed that curl_multi_timeout may return a very long
timeout value (e.g., 294 seconds and some usec) just before
curl_multi_fdset returns no file descriptors for reading. The
upshot is that select() will hang for a long time -- long enough for
an https handshake to be dropped. The observed behavior is that
the git command will hang at the terminal and never transfer any
data.
This patch is a workaround for a probable bug in libcurl. The bug
only seems to manifest around a very specific set of circumstances:
- curl version (from curl/curlver.h):
#define LIBCURL_VERSION_NUM 0x071307
- git-remote-https running on an ubuntu-lucid VM.
- Connecting through squid proxy running on another VM.
Interestingly, the problem doesn't manifest if a host connects
through squid proxy running on localhost; only if the proxy is on
a separate VM (not sure if the squid host needs to be on a separate
physical machine). That would seem to suggest that this issue
is timing-sensitive.
This patch is more or less in line with a recommendation in the
curl docs about how to behave when curl_multi_fdset doesn't return
and file descriptors:
branch: show targets of deleted symrefs, not sha1s

branch: skip commit checks when deleting symref branches
Before a branch is deleted, we check that it points to a valid
commit. With -d we also check that the commit is a merged; this
check is not done with -D.
The reason for that is that commits pointed to by branches should
never go missing; if they do then something broke and it's better
to stop instead of adding to the mess. And a non-merged commit
may contain changes that are worth preserving, so we require the
stronger option -D instead of -d to get rid of them.
If a branch consists of a symref, these concerns don't apply.
Deleting such a branch can't make a commit become unreferenced,
so we don't need to check if it is merged, or even if it is
actually a valid commit. Skip them in that case. This allows
us to delete dangling symref branches.

format-patch tests: check quoting/encoding in To: and Cc: headers
git-format-patch does currently not parse user supplied extra header
values (e. g., --cc, --add-header) and just replays them. That forces
users to add them RFC 2822/2047 conform in encoded form, e.g.
which is inconvenient. We would want to update git-format-patch to
accept human-readable input
--cc 'Jan H. Schönherr <...>'
and handle the encoding, wrapping and quoting internally in the future,
similar to what is already done in git-send-email. The necessary code
should mostly exist in the code paths that handle the From: and Subject:
headers.
Whether we want to do this only for the git-format-patch options
--to and --cc (and the corresponding config options) or also for
user supplied headers via --add-header, is open for discussion.
For now, add test_expect_failure tests for To: and Cc: headers as a
reminder and fix tests that would otherwise fail should this get
implemented.

Make add_rfc2047() and is_rfc2047_special() location dependent and include
all non-allowed characters to hopefully be RFC 2047 conformant.

The wrapping logic in strbuf_add_wrapped_text() does currently not allow
lines that entirely fill the allowed width, instead it wraps the line one
character too early.
For example, the text "This is the sixth commit." formatted via
"%w(11,1,2)" (wrap at 11 characters, 1 char indent of first line, 2 char
indent of following lines) results in four lines: " This is", " the",
" sixth", " commit." This is wrong, because " the sixth" is exactly
11 characters long, and thus allowed.
Fix this by allowing the (width+1) character of a line to be a valid
wrapping point if it is a whitespace character.

When we create an http active_request_slot, we can set its
"results" pointer back to local storage. The http code will
fill in the details of how the request went, and we can
access those details even after the slot has been cleaned
up.
Commit 8809703 (http: factor out http error code handling)
switched us from accessing our local results struct directly
to accessing it via the "results" pointer of the slot. That
means we're accessing the slot after it has been marked as
finished, defeating the whole purpose of keeping the results
storage separate.
Most of the time this doesn't matter, as finishing the slot
does not actually clean up the pointer. However, when using
curl's multi interface with the dumb-http revision walker,
we might actually start a new request before handing control
back to the original caller. In that case, we may reuse the
slot, zeroing its results pointer, and leading the original
caller to segfault while looking for its results inside the
slot.
Instead, we need to pass a pointer to our local results
storage to the handle_curl_result function, rather than
relying on the pointer in the slot struct. This matches what
the original code did before the refactoring (which did not
use a separate function, and therefore just accessed the
results struct directly).

Needs to be amended with Tested-by when a report comes...
test-lib: Fix say_color () not to interpret \a\b\c in the message
When running with color disabled (e.g. under prove to produce TAP
output), say_color() helper function is defined to use echo to show
the message. With a message that ends with "\c", echo is allowed to
interpret it as "Do not end the line with LF".
That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.
Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".
When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08). Newer versions are stricter:
The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@"). Do that.
Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651). Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.
Tested with Debian Subversion 1.6.12dfsg-6 and 1.7.5-1 and r1395837

git svn: work around SVN 1.7 mishandling of svn:special changes
Subversion represents symlinks as ordinary files with content starting
with "link " and the svn:special property set to "*". Thus a file can
switch between being a symlink and a non-symlink simply by toggling
its svn:special property, and new checkouts will automatically write a
file of the appropriate type. Likewise, in subversion 1.6 and older,
running "svn update" would notice changes in filetype and update the
working copy appropriately.
Starting in subversion 1.7 (issue 4091), changes to the svn:special
property trip an assertion instead:
$ svn up svn-tree
Updating 'svn-tree':
svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \
line 1583: assertion failed (action == svn_wc_conflict_action_edit \
|| action == svn_wc_conflict_action_delete || action == \
svn_wc_conflict_action_replace)
Revisions prepared with ordinary svn commands ("svn add" and not "svn
propset") don't trip this because they represent these filetype
changes using a replace operation, which is approximately equivalent
to removal followed by adding a new file and works fine. Follow suit.
Noticed using t9100. After this change, git-svn's file-to-symlink
changes are sent in a format that modern "svn update" can handle and
tests t9100.11-13 pass again.

revisions: initialize revs->grep_filter using grep_init()
Instead of using the hand-rolled initialization sequence,
use grep_init() to populate the necessary bits. This opens
the door to allow the calling commands to optionally read
grep.* configuration variables via git_config() if they
want to.
grep: move pattern-type bits support to top-level grep.[ch]
Switching between -E/-G/-P/-F correctly needs a lot more than just
flipping opt->regflags bit these days, and we have a nice helper
function buried in builtin/grep.c for the sole use of "git grep".
Extract it so that "log --grep" family can also use it.
grep: move the configuration parsing logic to grep.[ch]
The configuration handling is a library-ish part of this program,
that is not specific to "git grep" command. It should be reusable
by "log" and others.
builtin/grep.c: make configuration callback more reusable
The grep_config() function takes one instance of grep_opt as its
callback parameter, and populates it by running git_config().
This has three practical implications:
- You have to have an instance of grep_opt already when you call
the configuration, but that is not necessarily always true. You
may be trying to initialize the grep_filter member of rev_info,
but are not ready to call init_revisions() on it yet.
- It is not easy to enhance grep_config() in such a way to make it
cascade to other callback functions to grab other variables in
one call of git_config(); grep_config() can be cascaded into from
other callbacks, but it has to be at the leaf level of a cascade.
- If you ever need to use more than one instance of grep_opt, you
will have to open and read the configuration file(s) every time
you initialize them.
Rearrange the configuration mechanism and model it after how diff
configuration variables are handled. An early call to git_config()
reads and remembers the values taken from the configuration in the
default "template", and a separate call to grep_init() uses this
template to instantiate a grep_opt.
The next step will be to move some of this out of this file so that
the other user of the grep machinery (i.e. "log") can use it.
