Fix "git diff --stat" for interesting - but empty - file changes
The behavior of "git diff --stat" is rather odd for files that have
zero lines of changes: it will discount them entirely unless they were
renames.
Which means that the stat output will simply not show files that only
had "other" changes: they were created or deleted, or their mode was
changed.
Now, those changes do show up in the summary, but so do renames, so
the diffstat logic is inconsistent. Why does it show renames with zero
lines changed, but not mode changes or added files with zero lines
changed?
So change the logic to not check for "is_renamed", but for
"is_interesting" instead, where "interesting" is judged to be any
action but a pure data change (because a pure data change with zero
data changed really isn't worth showing, if we ever get one in our
diffpairs).
So if you did
chmod +x Makefile
git diff --stat
before, it would show empty (" 0 files changed"), with this it shows
which I think is a more correct diffstat (and then with "--summary" it
shows *what* the metadata change to Makefile was - this is completely
consistent with our handling of renamed files).
Side note: the old behavior was *really* odd. With no changes at all,
"git diff --stat" output was empty. With just a chmod, it said "0
files changed". No way is our legacy behavior sane.

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).

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
of Subversion trunk (1.8.x).

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.

git-svn: keep leading slash when canonicalizing paths (fallback case)
Subversion's svn_dirent_canonicalize() and svn_path_canonicalize()
APIs keep a leading slash in the return value if one was present on
the argument, which can be useful since it allows relative and
absolute paths to be distinguished.
When git-svn's canonicalize_path() learned to use these functions if
available, its semantics changed in the corresponding way. Some new
callers rely on the leading slash --- for example, if the slash is
stripped out then _canonicalize_url_ourselves() will transform
"proto://host/path/to/resource" to "proto://hostpath/to/resource".
Unfortunately the fallback _canonicalize_path_ourselves(), used when
the appropriate SVN APIs are not usable, still follows the old
semantics, so if that code path is exercised then it breaks. Fix it
to follow the new convention.
Noticed by forcing the fallback on and running tests. Without this
patch, t9101.4 fails:

When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.
When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.
However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.
For example, if you specify something along the lines of
branches = branches/project/{release_1,release_2}
and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch. By restricting the match regex
with anchors, this is avoided.

paint_down_to_common(): parse commit before relying on its timestamp
When refactoring the merge-base computation to reduce the pairwise
O(n*(n-1)) traversals to parallel O(n) traversals, the code forgot
that timestamp based heuristics needs each commit to have been
parsed. This caused an empty "git pull" to spend cycles, traversing
the history all the way down to 0 (because an unparsed commit object
has 0 timestamp, and any other commit object with positive timestamp
will be processed for its parents, all getting parsed), only to come
up with a merge message to be used.

t1450: the order the objects are checked is undefined
When a tag T points at an object X that is of a type that is
different from what the tag records as, fsck should report it as an
error.
However, depending on the order X and T are checked individually,
the actual error message can be different. If X is checked first,
fsck remembers X's type and then when it checks T, it notices that T
records X as a wrong type (i.e. the complaint is about a broken tag
T). If T is checked first, on the other hand, fsck remembers that we
need to verify X is of the type tag records, and when it later
checks X, it notices that X is of a wrong type (i.e. the complaint
is about a broken object X).
The important thing is that fsck notices such an error and diagnoses
the issue on object X, but the test was expecting that we happen to
check objects in the order to make us detect issues with tag T, not
with object X. Remove this unwarranted assumption.

mailinfo: don't require "text" mime type for attachments
Currently "git am" does insane things if the mbox it is given contains
attachments with a MIME type that aren't "text/*".
In particular, it will still decode them, and pass them "one line at a
time" to the mail body filter, but because it has determined that they
aren't text (without actually looking at the contents, just at the mime
type) the "line" will be the encoding line (eg 'base64') rather than a
line of *content*.
Which then will cause the text filtering to fail, because we won't
correctly notice when the attachment text switches from the commit message
to the actual patch. Resulting in a patch failure, even if patch may be a
perfectly well-formed attachment, it's just that the message type may be
(for example) "application/octet-stream" instead of "text/plain".
Just remove all the bogus games with the message_type. The only difference
that code creates is how the data is passed to the filter function
(chunked per-pred-code line or per post-decode line), and that difference
is *wrong*, since chunking things per pre-decode line can never be a
sensible operation, and cannot possibly matter for binary data anyway.
This code goes all the way back to March of 2007, in commit 87ab79923463
("builtin-mailinfo.c infrastrcture changes"), and apparently Don used to
pass random mbox contents to git. However, the pre-decode vs post-decode
logic really shouldn't matter even for that case, and more importantly, "I
fed git am crap" is not a valid reason to break *real* patch attachments.
If somebody really cares, and determines that some attachment is binary
data (by looking at the data, not the MIME-type), the whole attachment
should be dismissed, rather than fed in random-sized chunks to
"handle_filter()".
